imagine that the necessity for labour is only an evil must be either grossly ignorant or wilfully wicked4 ,whoever wastes his life in idleness1 either because he need not work in order to live1 or because he will not live to work1 will be a wretched creature1 and at the close of a listless existence will regret the loss of precious gifts and the neglect of great opportunities4 ,our daily work1 however common or humble it may seem1 is our daily duty1 and by doing it well we may even make it a part of our daily worship4 ,for these reasons the choice of a trade is a most important event in every boy's life1 and it is no less difficult than important1 because when a boy has just left school he seldom knows much about the operations of any trade1 and cannot be expected to express any preference for one more than another4 ,whether this book will be of any use in this respect1 by directing attention to some of the principal industries of the country in which we live1 must after all depend upon the tastes of each particular reader2 but it may at all events claim to be useful in making known what are the operations necessary to some of our great manufactures1 and in explaining the method of using the tools employed by those engaged in them4 ,a volume like the present can scarcely be said to have an ,author1 since much of its contents must necessarily be the work of the compiler1 who condenses the valuable material supplied by other writers1 and adapts it to his purpose4 ,it is impossible that any great part of the matter can be original2 and in some parts of the following pages the writer has found it altogether inexpedient to change even the manner of those who are regarded as the principal authorities on scientific subjects4 ,he believes1 however1 that even where he has borrowed1 he has borrowed with some discretion4 ,whether he has succeeded in explaining and simplifying the reader will be able to judge4 ,,the ,,brickmaker4 ,illustration3 ,,brickfield1 ,,shed1 ,,kiln1 ,c4 ,it would be very difficult1 and perhaps impossible1 to discover at what time in the history of the world the art of brickmaking was first practised4 ,in the earliest records of the human race the making of bricks is mentioned2 this was part of the labour imposed upon the children of ,israel1 when they were in captivity in ,egypt1 and bricks of excellent quality are found in some of the most ancient buildings1 the remains of which have been discovered4 ,though uncivilized nations1 and even some which had made great progress in civilization1 but lived in very warm or exceedingly cold climates1 frequently built dwellings of wood1 of wattles or strips of trees and branches covered with clay and lime1 and of rough stone and earth2 and though whole tribes lived and still live under tents1 or in mere log huts and wigwams1 or lodges made of the skins of animals1 the manufacture of bricks formed of clay1 and either burnt with fire or dried in the sun1 is amongst the oldest of all known trades4 ,in our own day it has arrived at such perfection and the varieties of bricks and tiles are so great in order to provide for the great diversity in buildings1 that it is one of the most important branches of ,english industry4 ,we learn from the ,bible that burnt bricks were used in building the ,tower of ,babel1 and from early historians1 as well as from recent discoveries1 we know that they were also made for the walls of ,babylon4 ,the bricks of the ancient ,egyptians were made of clay tempered with water and mixed with chopped straw1 and afterwards dried in the sun1 and the labour of the ,israelites was made more severe by their being compelled to find straw for themselves4 ,in ,rome both burnt or kiln-dried bricks and those dried in the sun were employed1 and though at a later date the art of brickmaking seems to have fallen into disuse1 it was revived again in ,italy after some hundreds of years4 ,the trade seems to have been brought to ,england by the ,romans1 and many of the most ancient buildings in this country are made of very fine brickwork1 though1 till the reign of ,elizabeth1 only large mansions were so built1 the common houses being formed of frame-works of timber filled in with coarse plaster supported by laths of wood4 ,there are few more interesting sights than a brick-field in full work with its great sheds1 its horses going slowly round and round in the mills1 grinding the clay which has been dug out of the deep pits2 its great stacks covered with hurdles and screens made of reeds and its immense kilns1 so cleverly and evenly built1 where the smoke rises lazily from the dull fires by which the drying or burning is completed4 ,illustration3 ,clay ,mill4 ,the methods of brickmaking differ considerably in various parts of ,england1 but that which we most commonly see in practice near ,london will very well represent them all1 and it is this which will now be described4 ,the earth used for making bricks is found after digging till the labourers reach the loamy soil lying just above that blue clay which is known as ,london clay2 and this earth is known as strong clay1 mild clay1 and malm1 and this earth requires preparation by mixing with them chalk and the dust of burnt ashes from the dust bins4 ,these burnt ashes the brickmakers call 8breeze40 ,the chalk mill and the clay mill are placed close together on large mounds1 high enough to allow the 8malm0 7which is a mixture of chalk and clay ground to a thin paste7 to run down to the brick earth4 ,the chalk mill is a round trough where the chalk is ground by heavy wheels fitted with spikes on their tires or hoops1 and turned by one or two horses4 ,the trough is supplied with water from a pump1 and the chalk1 as it is ground1 runs off by a wooden gutter into the clay mill1 where it is again stirred and ground till it mixes with the clay2 the mixture then runs through a grating and through other gutters to the brick earth1 which has been placed in heaps to receive it4 ,illustration3 ,hack ,barrow4 ,barrow4 ,when the earth is mixed in this way1 it becomes brick-clay1 and is taken in barrows up a sloping board1 to the pug mill4 ,the pug mill is a great tub1 the top of which is larger than the bottom1 and in the centre of it there revolves an upright iron shaft fitted with knives4 ,these knives cut and break the clay as it passes through the mill1 and they also force it downwards till it reaches the bottom1 where it passes through a hole on to a machine called the ,cuckhold1 which is a sort of table containing a trough where the clay is cut into lumps ready for the moulder4 ,illustration3 ,pug ,mill4 ,illustration3 ,barrow for carrying baked ,bricks4 ,illustration3 ,kick and ,stockboard4 ,mould4 ,board for ,moulding4 ,strike4 ,brick-mould4 ,the moulder who shapes the clay into bricks uses moulding sand1--a peculiar sort of sand brought from the bed of the river1 and spread out in the sun1 where it is turned over and over till it is quite dry4 ,it prevents the clay from shrinking1 gives a harder surface to the bricks1 and prevents them from sticking to the mould1 or to each other2 it also gives the ,london bricks their grey colour4 ,the moulder stands at the moulding stool1 which has a rim at each end to keep the moulding sand from falling off1 and has a stockboard1 which forms the bottom of the brick-mould1 and a page1 or two iron rods nailed at each end to wooden rails1 used to slide the raw bricks from the moulder to the place from which the 8taking-off boy0 takes them to place on the 8hack barrow10 by which they are carried away4 ,the moulder is served with the lumps of clay by the 8clot moulder40 ,the 8brick-mould0 is a kind of box without top or bottom1 and the moulder dashes the tempered clay into the mould with sufficient force to make the clay completely fill it2 after which the superfluous clay is removed from the surface of the mould with the strike4 ,the brick is then turned out on to a pallet or board1 on which it is wheeled by the boy to the 8hack ground10 where the bricks are built up to dry in low walls called 8hacks40 ,the brick moulds are made of brass or iron1 and often of wood4 ,sometimes the bricks are dried on a floor under a shed1 but often in the open air1 where they are covered with straw1 reed-flats1 or canvas and tarpauline screens1 to protect them from wet1 frost1 or excessive heat4 ,the bricks are afterwards burnt either in 8clamps0 or in 8kilns40 ,in clamp burning the bricks are built up close together1 and the bottom ones only are heated with burning breeze or cinders1 the heat spreading to those at the top4 ,a kiln is a sort of large chamber in which the bricks are loosely stacked with spaces between them for the heat to pass through1 and they are baked by fires placed either in arched furnaces under the floors of the kiln1 or in fire holes made in the side walls4 ,the kilns are built of various shapes1 and one of the principal arts in the trade of the ,brickmaker is to construct them that the heat may be properly distributed1 and the bricks equally and thoroughly baked4 ,illustration3 ,shovel4 ,pick4 ,reed ,flats4 ,,the ,,mason4 ,illustration3 ,,masons ,,at ,,work4 ,having already given a description of the way in which bricks are made1 we come to the work of the ,mason1 whose duty it is to prepare the stone work used in building and for other purposes4 ,in the mason's trade great skill is required1 as well as some hard manual labour1 since he has to cut the stones for arches1 windows1 columns1 cornices1 and porches1 into various shapes2 and to fit the separate pieces with perfect accuracy1 that the ,builder or the ,architect may be able at once to set them in their proper places4 ,the business of the monumental mason1 who erects pedestals for statues1 tombs1 and ornamental structures in parks and gardens1 is generally distinct from that of the builder or architectural mason1 although many of the same tools are used in both trades4 ,the stone used by the mason is of various kinds1 and is brought from different parts of the world2 but our own country contains stone of nearly every sort which can be well employed in ordinary building4 ,granite comes principally from ,scotland1 though a smaller quantity is brought from ,ireland2 red and white sandstone is plentiful in ,yorkshire1 ,lancashire1 and ,derbyshire1 as well as in ,scotland and ,ireland2 a sort of slate stone is found in ,wales2 and the most common building stone1 which is called limestone1 or free-stone1 is brought from several counties in ,england1 where it is constantly worked4 ,the stone is generally found under the surface of the earth1 and the places from which it is dug are called quarries2 the business of quarrying being to extract from the ground1 or from the sides of rocks1 large masses of stone or marble4 ,when these lie directly under the ground1 the earth at the top is removed1 and the stone is afterwards separated into blocks and lifted out by machinery2 but it is sometimes necessary to mine for the stone by making galleries underground1 and leaving pillars to support the earth above them4 ,in large quarries1 the earth at top is first removed1 and the first layer of stone1 which is generally of a common sort1 is broken or blasted with gunpowder1 and afterwards taken away4 ,the lower layers of stone are then divided by wedges driven into them1 until they split in the required direction2 the blocks are afterwards made of a regular square1 by a tool called a kevel1 pointed at one end and flat at the other1 and are then lifted by cranes on to low waggons1 upon which they are drawn away4 ,it is the business of the mason to work these stones1 which are to be used in building1 into their required shape2 but before the mason receives them the stone cutter hews and cuts the large blocks roughly into the form in which they are wanted2 and when the block is to form top of a doorway1 part of a cornice1 or any other portion of a building where ornament is necessary1 the carver executes these ornaments1 and cuts the stone into a pattern of fruit1 flowers1 or figures4 ,illustration3 ,peck or ,point4 ,stone ,axe4 ,when the stone is valuable it is sent from the quarry to the mason's yard1 or to the building where it is to be used in large blocks1 and there cut into slabs or thin pieces called 8scantlings10 of the required size1 with a stone mason's saw 7see large cut74 ,this saw differs from those used in other trades because it has no teeth4 ,it is a long thin plate of steel slightly jagged on the bottom edge1 and fixed in a frame2 and being drawn backwards and forwards in a horizontal position1 cuts the stone by its own weight4 ,to make this the easier1 a heap of sharp sand is placed on a sloping board over the stone1 and water trickling upon it from a barrel washes it into the cut made by the saw4 ,in large establishments the sawing of the stone is often effected by steam machinery4 ,some of the freestones are so soft as easily to be cut with a toothed saw1 worked backwards and forwards by two persons4 ,the tools used by the mason are the peck or point for chipping the surface of the stone1 the stone axe for breaking the irregular portions from the block1 the iron mallet and beetle1 for breaking pieces from the edge of the slab or driving in wedges4 ,illustration3 ,wooden ,beetle4 ,wedge4 ,iron ,mallet4 ,illustration3 ,rubber4 ,mallet4 ,brush4 ,chisels4 ,the tools used for cutting stone are the mallet and chisels of various sizes4 ,the mason's mallet differs from that used by other workmen1 being of a sort of half pear shape1 and with a short handle only just long enough to allow it to be firmly grasped in the hand4 ,the rubber is used for smoothing the surface of the stone1 after it has been worked by the tools2 sand and water are placed on the stone1 and the rubber is pushed backwards and forwards for the purpose of grinding the face of the slab to a smooth surface2 another block of stone is sometimes applied to the same purpose4 ,in ,london the tools used to work the faces of the stone are--the point1 a very small chisel only about a quarter of an inch broad at the cutting edge2 the inch tool1 which is a broader chisel2 the booster1 broader still2 and the broad tool1 which is three inches and a half wide3 beside these1 there are tools of the same kind for working mouldings and carvings4 ,illustration3 ,square4 ,bevel ,square4 ,straight ,edge4 ,trowel4 ,point4 ,besides these cutting tools1 the mason uses a banker or bench1 on which he places his stone for convenience of working1 and straight edges1 squares1 and bevels1 for marking the shapes into which the blocks are to be cut1 and seeing that his edges and surfaces are even by trying them as the work proceeds4 ,the bevel square is a square the stock1 or lower part1 of which is moveable1 so that it may be set to any angle or level as required4 ,sometimes a pattern called a templet is used for cutting a block to any particular shape1 and when the work is moulded1 the templet is called a mould4 ,moulds are commonly made of sheet zinc1 carefully cut to the profile of the mouldings with shears and files4 ,it often happens that the mason has not only to prepare the stone1 but to set it in its place in the building1 and this is properly part of his work4 ,he then uses the trowel1 for applying the composition for cementing the stones together2 lines and pins to show whether his edges are straight and square1 the square and level for a similar purpose2 and various rules for adjusting the stone faces of upright walls4 ,illustration ,,the ,,bricklayer4 ,illustration3 ,,the ,,bricklayer4 ,the ,bricklayer has so much to do with the erection of buildings that the ,master ,bricklayer is generally a ,builder2 that is1 he understands not only brickwork and the building of walls1 but also the other trades necessary for completing a house1 and can superintend the ,mason's1 ,carpenters'1 and ,plumbers' work4 ,of course1 the first consideration in building a house is the preparation of the foundations1 which are formed in various ways1 according to the nature of the soil on which they are laid2 unless the ground itself is firm enough to receive the walls1 sometimes thick layers of concrete 7a sort of mortar7 is used1 sometimes layers of planking are put down1 or even cross beams of timber1 and in some cases1 where the earth is very loose and damp1 timber piles are driven into it on which to lay the foundation4 ,the foundation once laid1 the vaults or cellars are built either in the ordinary way1 or in a series of arches of various forms2 then follow the abutments1 the wing-walls1 the main-walls1 with iron 8,bressumers0 for supporting those parts of the walls which are above large openings like great doors or shop fronts4 ,the partitions1 or interior walls1 may be either solid brick or stone1 or may be constructed entirely of timber1 or they may be frames of timber filled in with masonry or brickwork4 ,then come the floors1 the roofs and roof-coverings1 and finally the ceilings and the doors and windows4 ,the materials used in building are principally timber1 stone1 slate1 bricks1 tiles1 mortar1 lime1 cement1 iron1 glass1 lead1 zinc1 colours and varnishes4 ,those with which the working bricklayer has most to do are bricks1 slates1 tiles1 stonework1 cement1 and mortar1 for these are principally used in making walls and roofs1 which is the greater part of his trade4 ,the stone and slate come from the quarries1 and we have already seen how bricks are made4 ,mortar is made in the following way4 #ast4 ,the soft chalky stone known as limestone1 is calcined or burnt1 by exposure to strong heat in a lime kiln2 the heat drives off a gas which is contained in it 7called carbonic acid gas71 and leaves it in a state in which it is known as quick-lime4 #b;d4 ,the quick-lime is 8slaked10 by pouring water upon it1 when it swells and becomes very hot1 afterwards falling into a fine powder4 #c;d4 ,this powder is mixed into a rather stiff paste1 more water is added1 and when a certain quantity of sand is added becomes mortar1 and may be used for cementing bricks together4 ,concrete is made by mixing gravel1 sand1 and ground unslaked lime together with water2 it is used for foundations1 and filling in apertures requiring strength and firmness4 ,iron is used by the builder in two different states1 as cast iron and wrought iron2 the girders for supporting roofs and walls are mostly cast in moulds 7see ,iron ,founder71 though both these and other parts of the ironwork used in building1 are frequently of iron wrought by hand4 ,lead is used by the mason for securing and coating the iron clamps which hold the blocks of stone together2 it is also used in the plumbers' work of a house 7see ,plumber74 ,zinc is used in the manufacture of gutters1 pipes1 and portions of roofs4 ,illustration3 ,trowel4 ,the excavator having dug out the space where the foundation of the house is to be laid1 the work of the bricklayer begins1 and his tools are the trowel1 to take up and spread the mortar1 and cut bricks by a sharp blow to the requisite length2 then there are the brick axe or hammer1 for shaping the bricks to a level2 the tin saw for making an incision on bricks to be cut with the axe2 the rubbing stone on which to rub the bricks smooth in the parts where they have been cut1 and the mortar rake and shovel1 for mixing the mortar and cement4 ,illustration3 ,mortar ,rake4 ,crowbar4 ,shovel4 ,brick ,hammer4 ,pickaxe4 ,the crowbar and pick-axe are the tools used for demolishing old brickwork or clearing out rubbish2 the sieve 7see large cut7 for sifting the lime of which the mortar is made1 and the rammer for hardening the ground to render the foundation firm4 ,the raker is used for raking out the mortar from the joints of old brickwork which requires re-pointing1 or the joints refilled with mortar4 ,to 8set out0 the work1 which means to measure the spaces1 and to keep the lines1 curves1 and angles1 straight and true1 the bricklayer uses the square1 the level1 the plumb-rule2 the square shows whether the proper angle has been preserved2 the plumb-rule is an upright rule1 with a string at one end1 to which is attached a leaden ball4 ,if the work is straight on its perpendicular lines1 and the plumb-rule be applied to it1 this leaden ball will hang exactly in the centre1 and swing through a hole in the rule1 while1 if the work be crooked1 it will swing to one side4 ,the level is a rule on the same principle1 but for testing horizontal lines1 such as a cornice on the top of a wall4 ,the good bricklayer will frequently test his work by these tools1 and will also use a line stretched to two pins1 to guide him as he builds up his courses of bricks4 ,the bricks and mortar are supplied to him by a labourer1 who carries them in a hod4 ,the labourer also makes the mortar1 and builds up and takes down the scaffolding 7see large cut74 ,the scaffolding1 or that frame of poles and planks erected in front of the building as it is in progress1 is constructed of standards1 ledgers1 and putlogs4 ,the standards are poles made of fir trees1 from forty to fifty feet long1 and six or seven inches thick at the butt ends1 which are firmly fixed in the ground4 ,when one pole is not long enough1 two are lashed together1 the rope lashings being tightened by wedges driven in between the coils in a peculiar way4 ,the ledgers are horizontal poles placed parallel to the walls and lashed to the standards2 these support the putlogs1 or cross pieces1 which are about six feet long1 one end of them resting in the wall1 the other on the ledgers4 ,on these putlogs are fastened the scaffold boards1 which are stout boards with pieces of iron hoop placed round the ends1 to keep them from splitting4 ,illustration3 ,level4 ,cutting ,chisel4 ,square4 ,line and ,plumb4 ,hod4 ,a bricklayer and his labourer will lay about a thousand bricks1 or two cubic yards of brickwork1 in a day4 ,the tools used for tiling1 or placing the tiles on a roof1 are the lathing hammer1 the iron lathing staff to clinch the nails1 the trowel1 which is longer and narrower than that used for brickwork1 the bosse1 for holding mortar and tiles1 with an iron hook to hang it to the laths or to a ladder1 and the striker a piece of lath about ten inches long for clearing off the superfluous mortar at the feet of the tiles4 ,illustration ,,the ,,plasterer ,,and ,,whitewasher4 ,illustration3 ,,whitewasher ,,and ,,plasterer4 ,when the walls1 or what is called the carcase of the house1 have been built1 the roof made1 the inner walls and partitions set up1 and the joists and woodwork of the floors laid down1 the work of the ,plasterer begins4 ,he covers the brickwork and bare timbers of walls1 ceilings1 and partitions with plaster1 to prepare them for painting or papering3 he also forms the cornices for ceilings1 and the mouldings and decorations1 which are usually made in plaster or cement4 ,the materials which the ,plasterer uses for these purposes are3--#ast4 ,coarse stuff1 or a paste made with lime1 much in the same way as common mortar1 and afterwards mixed with hair1 which is obtained from the tanner's yard1 after it has been removed from the skins1 which are there made into leather4 ,this hair is raked together1 and mixed with the mortar1 with the hair hook1 and a sort of three pronged rake called the drag4 ,illustration3 ,hair ,hook4 ,fine ,sieve4 #b;d4 ,fine stuff is made from pure lime1 slaked with a small quantity of water1 after which enough water is added to bring it to a state in which it resembles cream2 it is then left to settle1 the superfluous water is poured off1 and the mixture is left in a tub1 till still more of the water has evaporated1 and it is thick enough to use4 ,this stuff is often used for ceilings1 and then a small quantity of white hair is mixed with it1 to help to make it firmer and more binding4 ,for these finer kinds of plaster it is necessary to use the fine sieve1 in order to sift the lime and other ingredients1 that only the portion which has been reduced to powder may be retained4 #c;d4 ,stucco1 which is made by mixing fine stuff with cleaned-washed sand4 ,stucco is used for house fronts1 or other finishing work1 which is intended to be painted4 #dth4 ,gauged stuff is used for forming cornices1 which run round a ceiling1 and for mouldings2 it is made by mixing fine stuff with plaster of ,paris1 which is a fine white powder easily made into a paste1 and drying very quickly4 ,these are only the ordinary materials used by the ,plasterer for his work1 but there are a great number of cements1 which are also applied in the course of his trade2 such as ,roman and ,portland cements1 and mixtures made and sold for special purposes of decoration1 and the manufacture of ornaments4 ,these ornaments1 such as centre pieces for ceilings1 flowers drooping from cornices1 bosses or groups on walls1 c4 are first modelled in clay1 and are afterwards cast in plaster of ,paris1 placed in moulds made of wax or plaster4 ,in this trade1 as in that of the picture frame maker1 ornaments are frequently made of papier mach1 or the pulp of paper 7literally smashed paper71 which is a very light1 hard1 and durable substance for the purpose4 ,the moulds for cornices are made of sheet copper1 and are fixed in a wooden frame4 ,illustration3 ,gauging ,trowel4 ,hammer4 ,salve4 ,plasterer's ,hawk4 ,check ,line and ,reel4 ,the various tools used by the ,plasterer are shown in the engravings1 and the manner in which some of them are used may be seen by the large cut at the commencement of this description of the ,plasterer's trade4 ,the peculiar hammer1 with one edge like an axe1 is used for breaking down old plaster1 and clearing away the mortar from walls and ceilings previous to plastering them afresh2 the hawk is a flat board with a handle in the centre1 used for holding the plaster or cement1 which is being laid on with the trowel4 ,the gauging trowel is the long narrow trowel1 used for taking up the fine stuff for cornices and mouldings2 these trowels are of various lengths1 from three to seven inches4 ,the salve is a sort of small spade1 on which the plasterer's boy lifts the mortar or cement1 and places it on the hawk1 which the workman holds in his hand2 as the salve has a long handle1 the plaster can be conveyed to the hawk even when the man is at work on a ladder4 ,the square is similar to that used by the bricklayer1 and shows that the corners of the work are straight and even2 the compasses are used for measuring distances2 the check line for marking out the spaces of the work to be done1 and the joint rules for measuring the parts where different portions of the work come together1 either at the corners1 or in making the mouldings4 ,the set square is also used1 for showing that the surface or the line of the work is straight and even4 ,illustration3 ,joint ,rule4 ,joint ,rule4 ,compasses4 ,set ,square4 ,when the ,plasterer has to cover a ceiling or a partition1 he commences by lathing4 ,this is nailing laths over the whole space which is to receive the plaster4 ,laths are long narrow strips of either oak or fir wood1 of various thicknesses2 the thicker being used for ceilings1 where they have to bear a greater strain than in upright walls4 ,the next operation is pricking up1 or placing the first coat of coarse stuff upon the laths2 this is called pricking up1 because when the plaster is laid1 its whole surface is pricked and scratched with the end of a lath1 that it may be rough enough for the next coat4 ,the laying on of this second coat of plaster is called floating1 and is performed in the following way4 ,the surface is surrounded with narrow strips of plastering1 called screeds1 held fast by lines of nails1 and these are made perfectly level1 by means of the plumb rule 7see ,builder's tools71 and the use of the hand float4 ,the spaces within these lines of plaster work are then filled with coarse stuff1 till the whole forms a flat surface1 which is made perfectly level1 or 8floated0 with the floating rule4 ,other screeds are then formed and filled up in the same way1 until the whole ceiling1 or wall1 forms one flat surface4 ,the operations are the same for ceilings and walls1 except that the plumb rule is used for adjusting the level of walls1 and the level for that of ceilings4 ,illustration3 ,square4 ,modelling ,tools4 ,brush4 ,floating ,rule4 ,after the work has been brought to an even surface with the floating rule1 the ,plasterer goes over it again with the hand float1 using a little soft stuff to make good any deficiencies4 ,illustration3 ,hand ,float4 ,when the floating is about half dry1 the setting or finishing coat of fine stuff is laid on1 and is first wetted with a brush1 and then worked over with a smoothing tool until a fine surface is obtained4 ,stucco is laid on with the largest trowel1 and worked over with the hand float--being at the same time sprinkled with water--until it becomes hard and solid2 after which it is rubbed over with a dry brush4 ,the water has the effect of hardening the face of the stucco2 which1 after several sprinklings and trowellings1 becomes very hard1 and as smooth as glass4 ,illustration3 ,setting ,trowels4 ,the commonest kind of ,plasterer's work is laying on one coat of stuff3 when this is done on brickwork it is called rendering1 and when on laths it is called laying4 ,when there is a second coat it is called render set1 or lath-lay and set3 and when it is three-coat work it is called render1 float1 and set1 or1 lath-lay1 float1 and set2 this is done in ceilings and partitions with fine stuff mixed with hair2 or1 when the walls are to be papered1 with fine stuff and sand4 ,rough stucco is used for finishing staircases and passages in imitation of stone4 ,it is mixed with a great deal of coarse sand1 and is not smoothed1 the hand float being covered with a piece of felt1 so that when it is applied to the stucco the grit of the sand sticks to it and is drawn to the surface1 giving the plaster the appearance of rough stone4 ,rough casting is used for outside walls1 and is done by throwing a layer of gravel1 mixed with lime and water1 over the second coat of plaster while it is quite wet4 ,in some counties of ,england1 and especially near ,nottingham1 the plasterers use reeds instead of laths2 and even floors are often made by laying down a quantity of coarse stuff upon a foundation of reeds4 ,these floors are almost as hard as stone1 and possess the good quality of being almost always fireproof4 ,illustration ,,the ,,carpenter4 ,illustration3 ,,the ,,carpenter',s ,,shop4 ,an account of the tools and implements used for working in wood would scarcely be complete without some remarks upon wood itself1 and you can have no better information on this subject than that which has been written by a gentleman#a who is thoroughly acquainted with the different kinds of timber1 and with all the materials used in building4 #a ,mr4 ,e4 ,,dobson1 ,assoc4 ,inst4 ,c4 ,e4 ,if we examine a transverse section of the stem of a tree1 we perceive it to consist of three distinct parts2 the bark1 the wood1 and the pith4 ,the wood appears disposed in rings round the pith1 the outer rings being softer1 and containing more sap1 than those immediately round the pith1 which form what is called the heart-wood4 ,these rings are also traversed by rays extending from the centre of the stem to the bark1 called medullary rays4 ,the whole structure of a tree consists of minute vessels and cells1 the former conveying the sap through the wood in its ascent1 and through the bark to the leaves in its descent2 and the latter performing the functions of secretion and nutrition during the life of the tree4 ,the solid parts of a tree consist almost entirely of the fibrous parts composing the sides of the vessels and cells4 ,by numerous experiments it has been ascertained that the sap begins to ascend in the spring of the year1 through the minute vessels in the wood1 and descends through the bark to the leaves1 and1 after passing through them1 is deposited in an altered state between the bark and the last year's wood1 forming a new layer of bark and sap-wood1 the old bark being pushed forward4 ,as the annual layers increase in number1 the sap-wood ceases to perform its original functions2 the fluid parts are evaporated or absorbed by the new wood1 and1 the sides of the vessels being pressed together by the growth of the latter1 the sap-wood becomes heart-wood or perfect wood1 and until this change takes place it is unfit for the purposes of the builder4 ,the vessels in each layer of wood are largest on the side nearest the centre of the stem1 and smallest at the outside4 ,this arises from the first being formed in the spring1 when vegetation is most active4 ,the oblong cells which surround the vessels are filled with fluids in the early growth2 but1 as the tree increases in size1 these become evaporated and absorbed2 and the cells become partly filled with depositions of woody matter and indurated secretions1 depending on the nature of the soil1 and affecting the quality of the timber4 ,thus ,honduras mahogany is full of black specks1 while the ,spanish is full of minute white particles1 giving the wood the appearance of having been rubbed over with chalk4 ,the best time for felling trees is either in mid-winter1 when the sap has ceased to flow1 or in midsummer1 when the sap is temporarily expended in the production of leaves4 ,an excellent plan is1 to bark the timber in the spring and fell it in winter1 by which means the sap-wood is dried up and hardened2 but as the bark of most trees is valueless1 the oak tree 7whose bark is used in tanning7 is almost the only one that will pay for being thus treated4 ,the seasoning of timber consists in the extraction or evaporation of the fluid parts1 which are liable to decomposition on the cessation of the growth of the tree4 ,this is usually effected by steeping the green timber in water1 to dilute and wash out the sap as much as possible1 and then drying it thoroughly by exposure to the air in an airy situation4 ,the time required to season timber thoroughly in this manner will of course much depend on the sizes of the pieces to be seasoned2 but for general purposes of carpentry1 two years is the least that can be allowed1 and1 in seasoning timber for the use of the ,joiner1 a much longer time is usually required4 ,properly seasoned timber1 placed in a dry situation with a free circulation of air round it1 is very durable1 and has been known to last for several hundred years without apparent deterioration4 ,this is not1 however1 the case when exposed to moisture1 which is always more or less prejudicial to its durability4 ,when timber is constantly under water1 the action of the water dissolves a portion of its substance1 which is made apparent by its becoming covered with a coat of slime4 ,if it be exposed to alternations of dryness and moisture1 as in the case of piles in tidal waters1 the dissolved parts being continually removed by evaporation and the action of the water1 new surfaces are exposed1 and the wood rapidly decays4 ,where timber is exposed to heat and moisture1 the albumen or gelatinous matter in the sap-wood speedily putrefies and decomposes1 causing what is called rot4 ,the rot in timber is commonly divided into two kinds1 the wet and the dry1 but the chief difference between them is1 that where the timber is exposed to the air1 the gaseous products are freely evaporated2 whilst1 in a confined situation1 they combine in a new form1 viz4 the dry-rot fungus1 which1 deriving its nourishment from the decaying timber1 often grows to a length of many feet1 spreading in every direction1 and insinuating its delicate fibres even through the joints of brick walls4 ,in addition to the sources of decay above mentioned1 timber placed in sea water is very liable to be completely destroyed by the perforations of the worm1 unless protected by copper sheathing1 the expense of which causes it to be seldom used for this purpose4 ,in modern houses the labours of the ,builder1 the ,mason1 and the ,plasterer1 would be of little use unless they were accompanied by that of the ,carpenter1 since a very large proportion of every building consists of the woodwork of which its interior structure is greatly composed4 ,as it is one of the most useful1 so the ,carpenter's may be considered the most ancient of trades1 for nearly all other handicrafts require the preparation or manufacture of the materials1 but the ,carpenter originally found his materials in the forest1 and at once set to work to construct various articles from the trunks and stems of the trees best suited for the purpose4 ,we can only imagine one trade older than that of the ,carpenter1 and that is the ,tool ,maker1 and as the earliest tools1 or at all events some portion of them1 were probably made of hard wood1 the ,tool ,maker may in some sense be said to have been a ,carpenter also4 ,illustration3 ,axe4 ,adze4 ,illustration3 ,saw4 ,compasses4 ,plumb ,rule4 ,hammer4 ,square4 ,mallet4 ,strictly speaking1 the business of the ,carpenter is only with the larger portions of buildings and the rough timber frameworks which support them1 and his principal tools are the axe and the adze1 for chopping and roughly smoothing timbers2 the saw1 for sawing beams and planks2 the chisel1 for making mortis holes for joining beams together1 and for cutting and paring wood2 the chalk line1 a line rubbed with chalk1 and used to make a straight line upon a board or beam1 to mark the direction in which it is to be sawn2 the plumb rule1 already described amongst the ,builder's tools2 the level2 the square2 the compasses2 all of which have been described in previous trades2 the hammer2 the mallet1 and various sorts of nails4 ,the other tools represented in the engravings belong more properly to the ,joiner1 but as the trades of the ,carpenter and the ,joiner are almost always united1 we will speak of all the tools as belonging to one business4 ,carpenter's work1 then1 consists of the framing roofs1 partitions1 and floors1 in making the various joints used in beams1 ties1 rafters1 and joists for supporting floors1 and the proper way of supporting buildings by posts and girders4 ,the ,carpenter requires to be strong and active1 that he may properly handle the heavy timbers on which he has to work2 he should have a knowledge of the science of mechanics1 that he may be able to provide for the strains and thrusts to which the different parts of his work are exposed1 and supply the proper means of resisting them2 and he should also be able to understand how to make what are called 8working drawings10 that he may 8set out10 or properly draw a plan of the work he has to do1 from the designs of the ,architect4 ,the ,carpenter being concerned with the portions of a building which are made of timber1 you will be better able to understand his trade by a short description of what these are2 and we will then speak a little of the ,joiner1 whose trade is generally confounded with that of the ,carpenter4 ,first3 ,partitions1 or inner divisions of a building1 may be either of brick1 stone1 or wood2 and1 in the latter case1 they are generally 8framed10 or supported in a more solid framework1 which should form a portion of the main building1 that is1 of the outer wall2 and should be quite independent of the floors1 which should not support1 but be supported by them4 ,second3 ,flooring is formed by joists or strong beams of timber reaching from wall to wall1 where they rest upon other beams1 called wall plates1 which are built into the walls themselves4 ,the floor boards are nailed over the upper edges of the joists1 and the lower edges receive the laths and plaster1 which form the ceilings of the rooms beneath4 ,large buildings are sometimes fitted with double framed floors1 with two sets of joists1 and building joists resting on girders2 and in superior houses1 the wall plates are often supported by 8corbels10 or1 portions of the timber projecting from the inside of the wall1 which prevents the necessity of opening the wall to admit the ends of the joists4 ,third3 ,roofing consists of the roof covering1 which is laid upon rafters or slender beams1 which are supported by stronger horizontal beams called purlins2 and these1 again1 rest on upright trusses1 or strong frames of timber1 placed on the walls at regular distances from each other4 ,upon the strength and firmness of these trusses1 and the skill of the carpenter's work1 depends the entire safety of the roof4 ,large roofs are supported by cross beams1 called collars1 or tie beams2 and they are further strengthened by an upright pillar in the centre1 called a ,king post1 from which slanting beams1 called 8struts10 support the rafters4 ,we have now only spoken of common roofs1 but there are many roofs of open timber-work in churches and other public buildings1 which are wonderful specimens of the skill of the ,carpenter and the ,joiner4 ,one of these1 perhaps the grandest as well as the most ancient1 is that of ,westminster ,hall2 but there is one also in the ,great ,hall1 at ,hampton ,court ,palace2 and others may be seen in ,churches and ,halls in various parts of ,england4 ,the ,joiner1 as his name implies1 frames and joins together the wooden finishings and decorations of buildings1 such as floors1 staircases1 skirtings1 door and window frames1 sashes1 or1 the sliding parts of windows that contain the glass1 shutters1 doors1 chimney-pieces1 c4 ,this work requires much greater nicety and finish than that of the ,carpenter1 and is brought to a smooth surface with the plane wherever it is likely to be seen1 while the carpenter's work is left rough as it comes from the saw4 ,the principal cutting tools used by the ,joiner are1 saws1 planes1 and chisels4 ,the saws are of various sizes1 and are called rippers1 half rippers1 hand saws1 and panel saws1 according to their shape1 and the number of teeth to each inch4 ,illustration3 ,chisel4 ,gouge4 ,screw ,driver4 ,screw4 ,tenon ,saw4 ,narrow ,saw4 ,the tenon saw is used for cutting tenons1 or flat slices from the ends of beams1 that other beams cut in the same way may rest upon them and yet leave a flat surface4 ,the thick back of the tenon saw keeps the blade from 8buckling10 or twisting2 as it would be very likely to do while sawing in a horizontal direction4 ,the dove-tail saw is similar to the tenon saw1 but smaller1 and with a brass back instead of an iron one4 ,it is used for dove-tailing1 or cutting notches in a board or beam1 into which projections in another board or beam are fitted1 in order that the two may be held together1 as we see the sides of a box are fitted to the back and front4 ,then there is the compass saw1 for circular work1 and the keyhole1 or narrow saw1 for cutting out holes4 ,the planes are used for bringing the edges and sides of beams1 boards1 or other wooden fitting1 to a perfectly smooth surface3 the first of these1 used upon the rough wood1 is called the jack plane2 another is called the trying or trueing plane2 and a third1 the smoothing plane4 ,illustration3 ,trying ,plane4 ,smoothing ,plane4 #b-;foot ,rule4 ,glue ,pot4 ,the plane1 as you will see1 is a solid piece of hard smooth wood1 with a hole in the centre containing the cutting tool1 or1 as it is called1 the plane iron1 which is firmly fixed with a wedge1 so that its sharp cutting edge only slightly projects at the bottom4 ,the wood which is to be smoothed is fixed on the joiner's bench by means of a screwed board1 called a shooting board1 and1 by means of the handle at the top1 the plane is made to slide swiftly along its surface1 so that the edge of the tool cuts off a thin shaving4 ,there are various sorts of planes besides these1 used for cutting various parts of the work1 but they are most of them of similar construction4 ,chisels are either for paring the wood1 and are used with the hand2 or are intended to cut into the thickness of the wood1 and are then struck with a large wooden hammer1 called the mallet4 ,the gouge is a curved chisel1 used for cutting mouldings or making round edges4 ,illustration3 ,clout ,nail4 ,cut ,clasp ,nail4 ,brad4 ,spike ,nail4 ,bradawl4 ,chisel4 ,gimlet4 ,the boring tools are the bradawl1 the gimlet1 and the stock and bit4 ,the bradawl is a small sharp wire fixed in a handle1 and used for making holes to receive large nails1 which1 if driven in at once by the hammer1 would split the wood4 ,nails are of various kinds1 the difference in which may be seen in the engraving4 ,the best kinds of nails are made from thin bar iron1 pointed1 cut off to the proper length1 and the head formed by stamping4 ,the gimlet is a hollow blade with a screw at the end1 and fixed to a cross handle4 ,it is used for boring a larger and rougher hole than the bradawl1 for receiving screws1 which are screwed into their place by the screw driver1 a sort of chisel1 the edge or point of which enters the notch in the head of the screw1 so that the workman may turn it round4 ,the bit is a tool not unlike a large bradawl1 which fits into a stock or handle4 ,the bits are of various sizes1 and are used for boring large holes4 ,illustration3 ,centre ,bit4 ,the brace and bit1 or centre bit1 is a tool with a centre and two sharp points1 one on each side2 it is placed in a bow-shaped stock with a round loose end4 ,this loose end the workman holds firmly1 while he places the point of the tool against the wood required to be bored2 he then turns the bow briskly round1 and the two points revolving rapidly1 cut out a circular piece4 ,the pincers are used for removing nails from wood1 and it is easy to see how they are applied4 ,there are some other tools which belong to the trade of the ,joiner1 but they are used less frequently1 and a description of them will be given when we have to say something of the trade of the ,cabinet ,maker1 whose work resembles the finer part of that which the ,joiner does at his own workshop4 ,the bench 7see large cut7 is the great table of thick planks supported on a timber frame1 at which the ,joiner works2 it is furnished with a 8side-board0 perforated with holes to receive a pin1 against which one end of the wood on which he is operating rests1 the other being firmly fixed in the bench screw4 ,illustration3 ,pincers4 ,illustration ,,the ,,house ,,painter ,,and ,,glazier4 ,illustration3 ,,house-,,painting ,,and ,,glazing4 ,although we have spoken of the trade of the ,plumber separately1 and have placed the ,painter and ,glazier together1 it generally happens that the three trades are carried on by the same persons1 and you will often have noticed 8,plumber1 ,painter1 and ,glazier0 over the fronts of shops1 where leaden pipes and taps1 casements1 and squares of coloured glass1 and specimens of 8graining10 or imitations of various woods in painting1 are placed for show in the windows1 to represent the different businesses carried on4 ,it is the duty of the ,house ,painter to cover with his colours such portions of the ,joiner's1 ,smith's1 or ,plasterer's work as require to be protected from the action of the air1 which would cause them to rust or decay4 ,he has also to choose the colours which will be best suited for decorating walls and cornices1 and generally to apply the proper shades for all the ornaments of the house1 and this part of the business1 which is called 8decorative painting10 requires a great degree of skill and taste in the workman1 who may properly be called an artist4 ,the materials used by the ,painter are principally white lead1 linseed oil1 spirits of turpentine1 8dryers10 and putty4 ,white lead1 which forms the basis of almost all the colours used in house painting1 is prepared by exposing strips of lead to the action of acid2 but the ,painter buys it ready made1 in the form of small cakes1 or lumps4 ,this white lead is used in all the under coats of paint1 and generally makes the body of most of the colours which are afterwards applied4 ,unfortunately1 while it is in the half-fluid state1 when it is used by ,painters1 it is very poisonous and unwholesome1 and many workmen suffer severely in their health from its use2 but it will be found that this is often caused by their own carelessness in working1 and by the want of personal cleanliness4 ,the ,painter should not only thoroughly wash his hands before every meal1 but as soon as his work is done should entirely change his clothes1 and wash hands and face thoroughly1 or even take a bath4 ,beside this1 he should wear1 over his working clothes1 a coarse linen frock or blouse1 which will protect him from the spots of paint1 and may be frequently washed4 ,linseed oil and spirits of turpentine are used for mixing and thinning the colours2 linseed oil is obtained from the seeds of the flax plant1 which are heated1 beaten1 and pressed by machinery1 until the greater part of the oil is extracted2 the seeds crushed into cakes are then used as food for cattle4 ,nut oil1 or the oil pressed from various kinds of nuts1 such as walnuts1 hazel and beech nuts1 is also frequently used for mixing colours where they are likely to be exposed to the weather1 but linseed oil is cheaper and is most generally adapted to the purpose4 ,oil of turpentine1 which the ,painter calls 8turps10 is the oil obtained by distilling crude turpentine2 and is used by the ,house ,painter to make his colours work more smoothly and freely in the brush1 to cause them to dry more quickly1 and to take away that shiny unpleasant glare that would otherwise be seen on the surface of paint mixed with linseed oil alone4 ,it is necessary1 too1 to take some means to make the linseed oil dry more rapidly than it would in its raw state2 or the paint would remain moist and greasy upon the walls for a very long time4 ,for this purpose the oil is boiled1 and is then known as 8boiled oil10 this is bought ready prepared1 the ,painter having by him preparations of lead or vitriol1 called 8dryers10 which he mixes with his colours1 after they are made1 in order to increase the rapidity with which they set upon the places where they are applied4 ,the ,painter has only a few tools1 and these are very simple2 they consist principally of the grinding stone1 or slab and muller1 for grinding his colours2 earthen pots for holding the paints2 cans for oil and turps2 a few tin pots1 or open cans and kettles1 for colour to be applied to outside places or walls where he has to work on ladders2 a palette knife1 for spreading the white lead on the stone1 or removing the paint to the palette1 for fine work1 or to the paint pot2 and brushes of different sizes4 ,illustration3 ,slab and ,muller4 ,paint ,pot4 ,palette ,knife4 ,oil ,can4 ,paint ,pot4 ,paint ,kettle4 ,the various colours1 which are mostly made from earths and minerals1 are purchased by the ,painter in powder or small dry lumps1 and have to be brought to a fine state1 and made quite free from grit1 before they can be used4 ,the slab1 or grindstone1 is generally of marble or porphyry1 and must have a perfectly smooth surface2 and the muller is a large oval or egg-shaped pebble1 with one end broken off1 and the surface made as smooth as that of the slab4 ,a small quantity of the colour which requires grinding is placed on the stone1 and moistened with a little oil2 and the muller is then worked over it1 by a circular movement1 until it is gradually driven to the edge of the stone4 ,the colour is then removed by the spatula1 or palette knife1 and placed in the paint pot4 ,illustration3 ,paint ,brushes4 ,in this state1 however1 the colour is too thick to use1 and of course requires to be thinned by adding the oil until it is sufficiently fluid4 ,in painting woodwork1 the first business is called 8knotting10 that is1 removing the turpentine from the knots1 which would otherwise ooze and spoil the paint4 ,they are first covered with fresh slaked lime1 which dries up and burns out the turpentine2 this is afterwards scraped off1 and the knots painted with a mixture of red and white lead mixed with glue size1 and afterwards with white lead and linseed oil4 ,when dry1 they must be rubbed smooth with a piece of pumice stone4 ,the next operation is to put on the 8priming10 which is the first coat of paint1 composed of red and white lead and linseed oil4 ,the nail-holes1 and other imperfections1 are then stopped up with putty 7a mixture of linseed oil and whiting1 made into a paste71 applied with the stopping knife2 and then the other coats of paint are laid on2 three coats being generally considered sufficient2 and the last being of the required colour4 ,illustration3 ,stopping ,knife4 ,the brushes used by the ,painter1 are either round or flat1 the latter being used in varnishing or graining2 they are made of hog's bristles4 ,the smaller kinds of brushes are called tools or fitches1 and are used for small surfaces1 such as ornaments and mouldings round panels1 when the colour is generally taken from a palette--a round slab of wood1 with a hole through which the thumb of the left hand passes in order to hold it4 ,the brushes must never be allowed to get dry1 but when not in use must be kept in water3 it is always best to keep a brush for each colour4 ,another part of the ,painter's business which requires more skill1 is graining and marbling2 or the imitation in colours of the marks and grains of various kinds of wood1 and the veins and spots in marbles4 ,this is of course a part of the trade which requires a knowledge of the thing to be imitated1 and great care and taste in doing it well4 ,graining is generally done with 8distemper colour10 that is a kind of paint in which whiting and size are used instead of white lead and oil1 for the basis of the colour2 but the colours depend on the sort of grain to be imitated1 and they are applied in various ways and with different sorts of brushes1 some of the colour being occasionally removed with a piece of wash leather1 in order to give the appearance of the light marks seen in the 8heart0 of the wood4 ,the appearance of the 8grain0 of the wood is effected by the graining comb1 a comb with short thick straight teeth1 which is drawn along the paint in a wavy line4 ,illustration3 ,graining ,comb4 ,painter's ,brush4 ,marbles are imitated in oil if it is outside work and exposed to the weather1 but for inside work distemper colour is frequently used4 ,occasionally walls are coloured in distemper1 and it then frequently happens that a pattern or some ornamental design is painted in the centres of the panels1 or round the mouldings4 ,this is a part of the ,painter's trade which requires much skill1 and a knowledge of artistic drawing and design4 ,varnishing is an operation requiring great care to perform it properly1 since it is necessary not only to choose the right kind of varnish1 but also to apply it to the surface of the paint with a light but firm hand4 ,varnishes are made of gums or resins melted1 spirits of wine1 oil of turpentine1 or strong white drying oil4 ,the hard varnishes dry rapidly1 and are made of the harder kinds of gums1 such as copal1 mastic1 c41 and the soft of ,canada balsam1 elemi1 turpentine1 c4 ,the most useful for the ,house ,painter are those of copal1 linseed oil1 and turpentine4 ,the brushes used in varnishing are generally flat1 so as to enable the workman to lay an even surface on the work4 ,varnishes are usually kept in wide-mouthed bottles2 from which they are poured into little tin pans with a false bottom above the real bottom1 the space between the two being filled with sand4 ,the use of this is that when the pan is placed over the fire1 the sand becomes heated1 and the varnish is kept a long time from becoming chilled4 ,illustration3 ,,the ,,glazier4 ,illustration3 ,glazing ,knife4 ,hacking ,knife4 ,chisel ,knife4 ,clicker's ,knife4 ,the trade of the ,glazier1 though now very important1 was unknown in this country till the eleventh century1 and even long afterwards the use of glass for windows was extremely rare2 pieces of horn1 and oiled paper1 supplying its place in almost every building except palaces and churches4 ,as we have here to do with the ,glazier1 and not with the manufacturer of glass1 we need say little about the method of making the materials used2 so that it will suffice to know that the 8crown glass10 mostly sold for windows of houses1 is composed principally of white sand1 pearlash1 and saltpetre4 ,this glass the ,glazier purchases in sheets of a circular form1 each of which is called a table1 since the mode in which it is made renders such a shape necessary2 and the first thing he has to learn1 is how to cut out square pieces of the proper size without wasting much of the round edge4 ,the glass when cut is fixed either into lead work or sashes2 the former of these is the oldest description of glazing2 and in the common kind the leaden frames are soldered together1 so as to form squares or diamonds2 the sides of the grooves in which the glass is placed being soft enough to bend back to receive the panes1 and then bend back again to hold them firmly4 ,in wooden sashes1 such as are now commonly used1 the space or frame for each pane of glass is 8rebated10 that is1 it has outside a small groove all round to receive the pane1 and a ledge against which it rests4 ,in this 8rebate0 each square of glass is placed1 and then firmly bedded and fastened smoothly with a rim of putty filling up the groove4 ,illustration3 ,rule4 ,square4 #b-;foot ,rule4 ,tilter4 ,the ,glazier uses a hacking knife for cutting out old putty from broken squares2 and the stopping knife1 or glazing knife1 for laying and smoothing the putty4 ,for setting glass into lead work1 the setting knife1 or chisel knife1 and the broad-bladed knife is used4 ,as much of the ,glazier's work is done outside the house1 he is sometimes compelled to use a board which is fastened with screws1 and projects from the window so that he may sit astride on the outside4 ,no one should ever attempt this where the sash can be easily taken out and the work done inside4 ,illustration3 ,diamond4 ,pincers4 ,the rest of the ,glazier's tools are a square1 and a straight edge rule for cutting against1 a two-foot rule1 and compasses for measuring2 pincers for breaking off the edges of glass that have been partially cut through2 and the diamond1 which is used for cutting1 and is his principal tool4 ,this is made of a small unpolished diamond fixed in lead1 and fastened to a handle of hard wood4 ,,the ,,plumber4 ,illustration3 ,casting ,lead4 ,in trades connected with building1 the work of the ,plumber is of so much importance that it must come next to that of the ,bricklayer1 and the ,carpenter4 ,at one time the ,plumber 7who takes his name from the ,latin word for lead#b7 was principally employed in making leaden roofs of churches or large public buildings and in forming casements for windows2 window frames being then made of strips of lead soldered or riveted together and holding the little diamond-shaped panes of glass between their edges4 ,in those days all the water used in the house was carried from the well or from the conduit in the main street1 or was brought in casks set upon wheels from the nearest running stream3 while rain-water for washing was collected in tubs or vats as it ran off the roofs4 ,not much more than a century ago the poets wrote of the misery of the streets of ,london on a wet night1 when there were no waste pipes to carry off the rain from the overcharged gutters on the tiles1 and nobody could venture out of doors without being half drowned by the sudden discharge of a shower bath from some overhanging gable4 ,then1 as there was no proper system of pipes for carrying off the wet1 there was very little drainage except by means of open gutters1 and the bye-ways1 as well as some of the principal thoroughfares and large houses1 were extremely unhealthy4 #b ,plumbum4 ,we are not quite perfect even yet in these respects1 and there are still neighbourhoods in ,london where a few ,plumbers might be able to make vast improvements2 but we are a great deal better off than our great grandfathers were4 ,the ,plumbers do not make quite so many leaden casements as they made in the olden time1 but they are well employed in constructing roofs2 carrying water into houses by means of leaden pipes2 making cisterns to contain a good supply of it1 and providing other pipes and gutters for conveying all the dirty water and drainage into the sewers that are under the roadway1 where it runs quite away from the streets1 and 7in ,london at least7 goes into the sea from near the mouth of the ,thames at ,erith4 ,illustration3 ,ladle4 ,grate4 ,soldering ,iron4 ,now as the ,plumber has to do a great deal of his work in roofs and other places where he is liable to fall1 he should be clear-headed1 and able to go up a ladder or look over a ledge at a height from the ground without being afraid1 and this is all the more necessary because he has to handle tools1 and sometimes to pour melted solder out of a hot iron ladle while he is at his work on these places4 ,for the purpose of melting the solder he has to carry his fire grate and melting pot with him to some place near where he is at work1 since unless the solder can be used rapidly it cools1 and will not make a sound joint4 ,the rest of the ,plumber's tools are the pouring stick for applying the melted solder in the places where it is required1 the soldering iron which is made red-hot1 and passed over the soldered joints to smooth them and make them all firm and sound2 the chisel1 shave hooks1 drawing knife1 and chipping knife1 for cutting the lead and scraping it on the surface1 or at the edges that are to be fastened together2 the hammers and mallets for beating the lead into shape and flattening the ridges1 the bossing mallet and dresser for bringing the sheet of lead to a proper shape1 and forming it over the ridge of a roof1 the chased wedge1 the screw-driver1 the dunring and the turnpin for various uses in making roofs1 laying down leaden pipes and fixing taps1 and the sucker hook used in repairing or fixing pumps when the part of the pump called the sucker requires to be rectified4 ,illustration3 ,pouring ,stick4 ,chipping ,knife4 ,dunring4 ,drawing ,knife4 ,chased ,wedge4 ,shave ,hook4 ,turnpin4 ,shave ,hook4 ,there are other tools beside these1 such as planes for making the surface of the lead smooth and even1 gouges and centre-bits for circular openings in the lead to receive nails or clamps1 measuring rules and compasses1 and pads of carpet or cloth to hold under a pipe when it is being soldered1 that the solder may be pressed round the joint before it cools1 and without its dropping on the ground4 ,illustration3 ,mallet4 ,hammer4 ,plumbers now buy their sheet lead as well as their leaden pipe at the warehouses1 but those in a large way of business formerly cast the lead themselves4 ,for this purpose they used a casting table1 which is a great wooden bench about six yards long and two yards wide1 made of smooth planks1 and with a raised wooden frame round the edge4 ,on this table the ,plumber spreads a layer of finely-sifted sand1 which was made level by a strike--a flat piece of wood with two handles--drawn from end to end of the table2 after this the surface was made still more smooth by a planer1 which was a flat plate of copper fastened to a handle4 ,illustration3 ,sucker ,hook4 ,screwdriver4 ,dresser4 ,bossing ,mallet4 ,chisel4 ,a trough called the pan ran along the whole length of the table1 and into this the melted lead was poured from the melting pot4 ,there were two ways of making the sheet lead3 one of them was to tilt the trough up1 and pour out the lead on to the table1 two men immediately passing a wooden strike over it so as to spread it evenly over the whole surface4 ,in this case the thickness of the sheet of lead depended on the distance between the edge of the 8strike0 and the surface of the sand4 ,another way was to have a narrow opening all along the bottom of the trough1 the trough itself moving from end to end of the table as the lead flowed out4 ,when this method was used the thickness of the sheet depended on the size of the opening1 and the rapidity with which the trough was moved along the table4 ,neither of these methods are now used1 the lead being rolled into sheets by machinery4 ,water-pipes are made by lead being cast in moulds with a steel rod passing through their middles1 according to the size required4 ,the lead is poured into the space between the rod and the mould4 ,after it is cool the rod is drawn out by machinery1 and the mould which is made in halves is opened and the pipe taken out4 ,the pipe is then much thicker and shorter than is required for use1 but it is afterwards drawn between powerful iron rollers with grooves cut in their surfaces1 an iron rod being again placed inside it4 ,as these grooves gradually decrease in size1 and the pipe is drawn through several1 it is very considerably lengthened1 and at the same time diminished1 in thickness1 by the time the operation is finished4 ,another method of making lead pipes is by the use of the forcing pump1 which pumps the melted metal out of the boiler into a mould containing a 8mandril10 or pipe of the required size4 ,pipes made in this way do not require to be rolled4 ,illustration3 ,forcing ,pump4 ,the work which the ,plumber is called upon to do on the roofs of houses requires experience before it can be properly performed4 ,the foundation of the roof which is to be covered with lead is made either of boards or plaster1 so that the surface may be even1 and if it be of boards they must be thick and well seasoned to prevent their warping4 ,the foundation slopes a little in order to carry off the rain towards one end4 ,when the roof is so large that it needs two widths of lead1 there are three ways of joining the edges of the lead together3 one is by fastening to the roof long slips of wood 7flat at bottom and round at top7 at the places where the lead will be joined4 ,over these strips the edge of the first sheet of lead is folded and hammered down quite close1 then the edge of the second sheet is folded and hammered over that1 so that water cannot get between them4 ,this is called 8rolling40 ,another method is to bring the two edges up just as though they were to be sewn together1 then to fold them tightly one over the other1 and hammer them down3 this is called 8overlapping10 but it is not so good as rolling for keeping out the rain4 ,the third way is to solder the edges together3 the solder1 which is in constant use by the ,plumber1 being a metal made by mixing lead and tin together4 ,these two metals when mixed adhere very strongly to the lead that they are meant to join1 and the surface to which they are applied is made hot enough to unite with the solder by means of the soldering iron1 while very often a little resin1 borax1 or tallow is placed on the surface of the lead to cause it to combine more rapidly with the molten metal4 ,besides the fixing of roofs the ,plumber makes leaden cisterns1 fixes rain-water gutters1 and waste pipes1 and arranges taps and drains2 and in some of these operations he will use zinc instead of lead4 ,not the least important part of his business1 however1 is the construction and arrangement of pumps1 and for this purpose it is necessary that he should study mechanics1 and those branches of science which refer to the properties of water1 and to the laws which govern the air and other fluids4 ,he is always the best workman who goes to his business with a knowledge of the natural laws and scientific facts connected with it1 and a very little study will save a world of blundering2 during which the ignorant man will remain a labourer1 because it takes him half a lifetime to learn his business4 ,illustration ,,the ,,gasfitter4 ,illustration3 ,,gasfitters ,,at ,,work4 ,as there are now few large houses which are not lighted by gas1 the trade of the ,gasfitter is one of considerable importance2 and though the materials used are generally bought ready made from the ,brassfounders1 the glass-works1 the ,ironfounders1 or the lead warehouse1 considerable skill is required1 as well as some taste in properly adapting the chandeliers and burners1 and skilfully adjusting the tubes and pipes so that they may easily be repaired1 or any escape of gas quickly detected4 ,the various tools used by the ,gasfitter are simple enough1 but careful practice is necessary for their proper use2 and1 as any flaw or imperfection in the work may lead to very dangerous consequences1 all the operations should be thoroughly tested1 and every joint and fitting in the various parts made sound and strong4 ,before the gas is taken into a house1 or as it is called in the trade 8laid on0 in the house1 it is of course necessary to obtain the permission of the ,company to whom the works where the gas is made belong1 and to agree to pay for the quantity that is burnt1 which is charged by the thousand cubic feet1 and varies in price according to the cost of the coal from which it is made1 and the difficulty of conveying this coal to the works4 ,illustration3 ,spade4 ,crowbar4 ,rammer4 ,the first operation is to take up the roadway in front of the house1 in order to connect the pipe which is to convey the gas to the meter with that which conducts it from the works to the different streets of the neighbourhood4 ,for this purpose the spade and crowbar are necessary1 while sometimes the pickaxe also has to be used2 and the rammer serves to beat the earth down more closely after the pipe is laid4 ,illustration3 ,brick ,bit4 ,brick ,auger4 ,the pipe which is joined to the larger pipe1 or main1 is generally of iron1 and is made with a screw and socket1 that it may not be easily displaced by the pressure of the roadway or footpath1 and this1 passing into the basement of the house1 supplies the gas to the meter4 ,the meter is a mechanical contrivance1 which is so constructed that the quantity of gas passing through it is registered by a plate something like a clock face1 with a hand to point to the figures which represent the number of cubic feet consumed4 ,there are different kinds of meters1 and the construction of them varies very considerably1 but they all answer this purpose3 so that when the inspector visits the house once a quarter he may directly see what quantity is to be charged for4 ,the pipe leading from the meter is fitted with a strong tap1 by turning which1 all the gas may be shut off from the tubes that convey it to the different burners in the house1 and from this pipe the smaller pipes 7made of a sort of solder or of lead7 are taken to the various rooms4 ,in order to carry the tubes through a wall1 it is necessary to use the brick bit and the brick auger for boring a hole to receive it1 while to support it against a wall or along the top of a ceiling the ,gasfitter uses wall hooks1 the hammer and the tongs for holding and bending the pipe to its proper direction4 ,in kitchens and basement rooms the pipe is generally carried from the meter up the wall and along the ceiling to the place where the burner is to be fixed3 but in upper rooms the pipe is taken up the house wall1 and carried under the flooring of the room above to the centre of the middle joist1 where a hole is bored quite through the ceiling of the room below4 ,for this purpose the twisted auger is generally used2 and for the preliminary work of taking up the floor and cutting a groove in the joist to receive the pipe1 that it may not be injured by the pressure of the boards above1 the saw and the hammer are required4 ,illustration3 ,wall ,hooks4 ,nuts4 ,grease ,pot4 ,hammer4 ,illustration3 ,twisted ,auger4 ,saw4 ,blowpipe4 ,tongs4 ,illustration3 ,waxed ,rushes4 ,rasp4 ,of course one length of pipe is not sufficient to go to any great distance1 and a joint has frequently to be made1 the solder used for this purpose being so easily melted and so readily combining with the pipe itself1 which is of almost the same material1 that the flame from prepared tow blown to an intense heat by the blow pipe is sufficient for the purpose4 ,the rasp is used for filing the surface at the ends of the pipes where they are to be joined1 and the waxed rushes to try the joints in order to see that there is no escape of gas through some small hole4 ,when the pipes are all laid and brought to their proper positions the fittings are fixed4 ,those which descend from the centres of ceilings are generally called chandeliers1 and consist of a tube of metal fastened to the gas pipe1 the end of which coming through the ceiling is furnished with an iron screw to fit the end of the tube4 ,this tube is placed within a larger tube1 from the bottom of which a still smaller one passes within the first4 ,the gas therefore descends the tube from the ceiling1 and enters the smallest tube1 which communicates with the burners that spring from the largest4 ,the larger tube is intended to receive water1 in which the end of the first tube rests1 so that the gas is prevented from escaping1 while by a nice adjustment of weights running over pulleys attached to the larger1 the burners can be raised or lowered1 as one tube slides within the other 7see large cut74 ,the taps are placed at the burners to turn on or turn off the gas as it is required1 and in order to fix and screw these1 as well as to fasten joints in the fittings by means of screw nuts1 the pliers and the wrench are used4 ,illustration3 ,wrench4 ,tow4 ,tap4 ,rimmer4 ,clamps4 ,pliers4 ,drill ,stock4 ,the clamps are a sort of vice with grooved holes1 for holding the taps and metal joints firmly while they are filed or otherwise prepared2 the drill stock is used for boring small pipes in order to make a branch to some other direction1 and the drill brace is intended for boring the main pipes1 under which the large hooks are placed while a stock and bit attached to the upper screw makes the hole2 the ordinary braces are fitted to a ratchet or cog wheel at one end1 and are also used for making incisions by being worked backwards and forwards4 ,illustration3 ,drill ,brace4 ,braces4 ,stocks and ,dies4 ,the several kinds of burners are pierced or cut in such a way as to make the flame from the gas of different shapes1 such as fish tail1 cock spur1 star1 or argand1 the names of which tell pretty well in what shape they appear4 ,small rooms are sometimes fitted with 8telescopes0 instead of chandeliers1 the telescope being one tube sliding within another1 and the space carefully filled with a properly adjusted cork or some other flexible and impervious substance4 ,bedrooms1 and apartments where light is required at the walls or chimney pieces1 are furnished with brackets1 which either simply project from the wall1 or are made with an arm moving on a ball and socket joint4 ,the manufacture of the various portions of the apparatus used in gas fitting will be mostly found described under the trade of the ,brassfounder4 ,illustration ,,manufacture ,,of ,,gas4 ,illustration3 ,,gasometers4 ,very few of the readers of this book will remember the appearance presented by ,london streets before the introduction of gas2 when all the thoroughfares were darker than even the commonest streets are now1 and the only light emanated either from the shop windows or from dim oil lamps1 which the rain or the wind would frequently put out1 even when they did not burn out of themselves for want of being trimmed and replenished4 ,a century ago these oil lamps were quite insufficient to light even the main streets1 and people who walked out at night generally hired a 8link boy0 to light them as they went1 with a great flambeau of hemp and pitch1 which smoked and smelt insufferably4 ,the nobility and gentlefolks who rode in carriages were also attended by footmen with flambeaux of a better sort1 and outside the doors of some of the oldest houses in ,london there may still be seen the great iron extinguishers attached to the railings1 where the torch-bearers put out their lights till it was time to escort their masters and mistresses home4 ,the poet ,gay1 who wrote the celebrated fables1 describes the link boys1 and gives them rather a bad character for so often being connected with the bands of thieves and footpads which infested ,london streets1 and robbed people with impunity in the dark4 ,he says3-- 8,though thou art tempted by the link man's call1 ,yet trust him not along the lonely wall2 ,in the midway he'll quench the flaming brand1 ,and share the booty with the pilfering band4 ,still keep the public streets1 where oily rays1 ,shot from the crystal lamp1 o'erspread thy ways40 ,long before this1 however1 the inflammable nature of the vapour which streamed from burning coal had been observed by scientific men1 and it was thought by many people that some method might be invented for making this gas useful for the purpose of lighting streets or houses4 ,it had also been observed that the air suddenly escaping from the shafts of coal mines was often highly inflammable1 and some experiments were made in the distillation of coal as early as #agbf4 ,in #agfe ,lord ,lonsdale proposed to the magistrates of ,whitehaven to convey the gas from the neighbouring mines through pipes for lighting the town4 ,a number of eminent men afterwards made experiments with gas1 but no decided practical result followed until a ,mr4 ,murdock1 of ,cornwall1 began to manufacture gas for lighting his house and offices at ,redruth4 ,in #agih the same gentleman used gas for lighting the ,soho ,foundry1 where four years afterwards a public exhibition of the new invention was made by means of an illumination to celebrate the proclamation of peace4 ,in #ahjc a gentleman named ,winsor first publicly showed at the ,lyceum ,theatre1 in ,london1 a system of illumination by gas1 which was the commencement of our present method of lighting our streets and houses2 and after great difficulties and various experiments1 a company was formed for the purpose of carrying out the undertaking of superseding the old oil lamps and making use of the new invention4 ,the premises of the company and their factory were situated in ,pall ,mall1 where the ,carlton ,club now stands1 and the lights first appeared from the corner of ,st4 ,james's ,street to the ,haymarket1 while several jets were placed in front of ,carlton ,house1 the residence of the ,prince ,regent1 afterwards ,george the ,fourth4 ,by slow degrees1 and by the assistance of ,mr4 ,clegg1 an eminent engineer1 the manufacture of gas improved1 and in #ahad1 when the allied sovereigns visited this country1 and a general illumination was ordered1 a magnificent pagoda in ,st4 ,james's ,park was erected for the exhibition of the new light4 ,the following year ,guildhall was fitted with gas burners2 and1 although it had been predicted that the new invention would ruin the navy by superseding the use of the oil brought by the whalers1 and though some people declared that it was only a scheme for blowing up ,london1 the success of these experiments led to its rapid adoption in most of the large towns of ,europe4 ,it will now be necessary to say something of coal1 of which more than #djj1jjj tons are used every year for the manufacture of gas in ,london alone4 ,the name coal was originally given to any substance used for fuel1 and the use of mineral coal1 or1 as it was formerly termed1 sea-coal1 from the fact of its being brought by sea1 has not prevailed for longer than #bjj years4 ,coal is found in this country in extensive deposits called coal-fields1 the most important of which are3--#a4 ,those of the great northern district1 including the coal-fields north of the river ,trent4 #b4 ,those of the central district1 including the ,leicester1 ,warwick1 ,stafford1 and ,shropshire coal-fields4 #c4 ,those of the western districts in ,north ,wales1 ,south ,wales1 and ,gloucester4 ,the coal occurs in a number of layers1 or beds1 termed seams1 and these are separated from each other by layers of slatey clay1 called shale1 and coarse1 hard sandstone1 known as grit4 ,the seams of coal are mostly comparatively thin1 but varying from a few inches to six or eight feet in thickness1 and underneath the layers is usually found a bed of mountain limestone extending beyond the coal-field1 and rising to the surface of the ground around it4 ,the first process for finding coal is to bore with iron tools a perpendicular hole in the ground2 then if coal is discovered1 a shaft1 or pit1 from ten to fifteen feet in diameter1 is sunk1 and lined with brick1 cast iron1 or wood1 to prevent the admission of water and the falling in of the sides4 ,when the shaft reaches a seam of coal1 passages are made1 twelve to fourteen feet wide1 and varying in height with the coal2 from these proceed smaller ones1 which are again crossed by large ones1 enormous blocks of coal being left to support the earth above4 ,as the mine becomes larger1 a second shaft is sunk at some distance from the first1 in order that air may be supplied to the mine1 and that the gas that escapes from the coal may be carried away4 ,a current of air is caused by burning a large fire in one shaft1 and the draught is directed to the part of the mine where it is required1 by doors1 which close up some of the passages and leave others open4 ,there are several varieties of coal found in this country4 ,the most important are3 the common1 or bituminous coal1 which soils the fingers on handling2 the cannel1 or candle coal1 which burns with a bright flame1 but does not soil2 the anthracite1 or culm coal1 which burns without flame1 does not form cinder when half consumed1 and is most useful for furnaces1 in consequence of its intense heat and the absence of smoke4 ,although often classed amongst the minerals1 coal is evidently of vegetable origin2 many sorts of it being distinctly fibrous1 and showing the grain of the wood from which it is composed4 ,upon examination with the microscope1 coal shows vegetable remains2 and these are frequently so perfect that they prove its formation from such plants as ferns and fir-trees1 of a kind somewhat different from those which now exist4 ,the value of coal depends entirely upon its inflammable and combustible properties4 ,it is used as the source of artificial warmth in our dwellings1 and our manufactures are mainly dependent on it4 ,without coal there would scarcely be any working in iron1 copper1 lead1 or other metals1 as in populous countries the supply of wood is soon exhausted4 ,our potteries and our glass works are also carried on by its use1 and the power of steam which moves all our great engines and machines is dependent on coal for its existence4 ,great ,britain produces more than one-half the coal that is consumed in the world1 and about #ahj1jjj persons are employed in obtaining it in our collieries4 ,the first process in the manufacture of gas is to subject the coal to a great heat1 by which it is carbonised1 or burnt until only the cinder1 or coke1 remains after the gas has flown off4 ,this is done by placing the coal in retorts of fire-clay or iron1 which are previously heated4 ,these retorts1 which occupy a building called the retort house1 having been charged with coal1 are perfectly closed1 and the door luted1 or stopped1 with a sort of cement1 so that the gas can only escape up the ascension pipe1 the coke being left in the retort4 ,illustration3 ,retort ,house4 ,the gas from the coal then passes through the ascension pipe by what is called the dip pipe1 into a main1 a large horizontal tube extending along the length of the furnaces4 ,this main is about half filled with water or tar1 in which the ends of the dip pipes are immersed1 so that as the gas runs in1 it ascends through the liquid into the space above1 but cannot flow back again into the dip pipes4 ,in this way it is all collected in the upper part of the main pipe1 and is ready for purification4 ,where double retorts are used1 each end is worked with at least three stokers1 and an extra man for preparing the lids of the mouth-pieces4 ,others are required for extinguishing the coke1 wheeling the coal into the retort house1 clinkering furnaces1 and attending to fires4 ,three stokers1 assisted by a man to extinguish the coke1 will perform all the work of taking off the lids1 raking out the coke1 extinguishing and wheeling it away from a bench of seven retorts1 in twelve or thirteen minutes2 they will then put the proper charge for each retort in the scoop1 deliver its contents1 and be ready for charging another bench in a further space of seven minutes1 while a fourth workman will in the meantime have put on the lids1 so that the whole work of discharging and charging the seven retorts will occupy barely twenty minutes4 ,this extreme dexterity is of course only acquired by long practice1 and it must be admitted the labour is very severe2 but this is moderated by the time the men have for repose between the charges4 ,the first process in discharging or drawing is for one or two of the men to relieve the screws of the mouth-pieces of the retorts about to be discharged1 by giving three or four rapid turns2 another man instantly gives a knock to each of the cross bars to disengage them from the ears of the lid1 and at the same time strikes the lid a blow with a piece of iron or hammer1 in order to break the luting1 and a light is immediately applied to prevent explosion1 which would be likely to crack the retort if of clay4 ,for want of this precaution1 many lamentable accidents have happened through the gas exploding when combined with atmospheric air4 ,the men then lift off the cross bar and screw of each retort1 placing them on the ground1 and then each seizes hold of a lid in both hands1 lifting it by the projecting ears1 and placing it aside to cool1 ready for luting for another charge4 ,illustration3 ,fender4 ,wheelbarrow4 ,bus4 ,three of the stokers then take up their iron rakes1 which are simply rods of -inch iron1 about #ab feet long1 having a handle at one end2 the other end being turned at right angles is flat1 about #f inches long1 #b inches wide1 and -inch thick4 ,these are inserted in the retort1 and the red-hot coke drawn to the mouth1 whence it drops into the coke vault1 where there is a man ready to extinguish by throwing water on it2 or when there is no vault the coke drops into iron barrows placed ready to receive it1 and wheeled rapidly away when the charge is withdrawn4 ,if the coke were not immediately extinguished it would smoulder1 and the surface become covered with earthy ash1 and detract from its appearance and value4 ,illustration3 ,rake4 ,clinkering ,spud4 ,scoop4 ,fire ,shovel4 ,key4 ,auger4 ,formerly1 in charging retorts1 the operation being comparatively very protracted1 there was a considerable loss of gas1 in addition to the time and extra fatigue to the men4 ,in order to remedy these inconveniences1 a method has been contrived for depositing the whole charge in the retort at once2 for this purpose an iron scoop is used1 this being a semi-cylinder of sheet iron1 from #h to #aj feet long and #aj or #ab inches diameter1 with a cross handle at the end to assist in lifting and turning it round to empty the coals in the retort4 ,illustration3 ,shovel4 ,clinking ,bat4 ,the charge of coal is placed in the scoop while it rests on the ground1 having a bent rod underneath for the purpose of lifting it3 one man takes hold of the cross handle1 and two others lift the other end by the bent rod1 and introduce it into the mouth of the retort4 ,the scoop with its contents is then pushed forward to the further end1 turned completely over1 and immediately withdrawn1 leaving the coal in the retort1 which is raked into a layer of uniform thickness1 when the lid1 previously luted and ready1 is placed in its position and screwed up as quickly as possible4 ,the operation of charging a retort with the scoop does not occupy more than thirty or forty seconds1 so that very little escape of gas can take place4 ,the shovel is used for lifting the coal to the scoop1 the clinking bat for breaking or removing the coke in the vault1 the spud for a similar purpose4 ,the gas in the hydraulic main is of course very impure1 having undergone no alteration since it came from the coal in the retort4 ,it contains a quantity of tar and ammoniacal liquor in vapour1 and these have to be separated from it and this can be effected by what is called condensation1 the instrument used being known as a condenser4 ,there are two or three forms of condensers in use1 but a common one1 which is represented in the engraving1 is called the horizontal condenser1 and is a rectangular box or chest formed of cast iron plates1 put together with flanges1 and perfectly tight joints4 ,its interior is provided with a series of iron trays1 containing each about two inches in depth of water1 and so arranged that the gas1 entering at the bottom of the chest1 passes in succession over the surface of the water in each tray1 and traversing the whole length of trough ten or twelve times1 passes off at the upper side4 ,in the mean time a continuous stream of water enters at the top1 and in its descent absorbs a portion of the ammonia1 at the same time cooling and condensing the vapours in combination with the gas4 ,illustration3 ,condensers4 ,horizontal condensers are sometimes composed of a series of pipes placed in a horizontal position1 and immersed in water4 ,illustration3 ,wet ,purifier4 ,the other form of condenser1 which is very generally employed1 consists of a series of vertical pipes1 connected in pairs by semicircular bends at top1 and attached to a cast-iron box or chest at bottom4 ,this chest has a series of divisions1 the ends of which are sealed by liquid placed therein1 so that the gas in its passage has to pass through the whole series of pipes4 ,the pipes by their contact with the atmosphere radiate the heat acquired from the gas in its passage1 and it being in consequence cooled1 deposits the vapours as liquid in the form of tar1 and water saturated with ammonia1 generally called ammoniacal liquor4 ,this condenser is sometimes used with an application of cold water on its exterior1 in order to increase the cooling effect4 ,the other part of the purification is by a chemical process1 in which a solution of lime is used to remove other impurities in the gas4 ,this is called wet lime purification1 or when the lime is only slackened 7or moistened7 it is called dry lime purification1 and the process takes the sulphuretted hydrogen1 the carbonic acid1 and other matters from the gas before it is stored for use4 ,illustration3 ,dry ,purifier4 ,the wet lime purifier consists of a cast-iron cylinder entirely closed at top and bottom1 except where the inlet and outlet pipes join it1 and where an opening is required for charging it with lime-water1 which same opening is also used for drawing off the charge4 ,to the inside of the cover of this outer cylinder is bolted an inlet cylinder usually made of wrought-iron plate4 ,this inlet cylinder is open at the lower part1 and reaches to within a foot from the bottom of the outer cylinder1 but has bolted to its lower flange a wide ring or dash plate of sheet iron1 the outer diameter being only #h or #i inches less than that of the outer cylinder1 so that a space of about #d or #e inches is left between the outside of the ring and the interior of the large cylinder4 ,the gas passes down through the inlet cylinder1 and by its pressure forces its way up through the fluid lime1 the surface of which is #h or #i inches above the dash plate4 ,the wet lime purifiers are variously worked2 when four are used1 two vessels are employed at one time1 and when the lime in the first is incapable of absorbing the impurity1 that purifier is put out of action1 and the second and third are worked1 and so on in succession4 ,when quick lime is slackened1 reduced to powder1 and slightly moistened with water1 chemically this is called the hydrate of lime1 and is often employed to absorb the sulphuretted hydrogen and carbonic acid from the gas4 ,the process is termed dry lime purification4 ,dry lime purifiers are generally rectangular cast-iron vessels1 varying from #c feet to #cj feet square1 and from #c feet to #d feet #f inches deep4 ,sometimes in small works they are made circular2 this1 however1 is not very frequent1 and is done for convenience or economy in construction4 ,each purifier contains a series of perforated shelves1 trays1 or sieves1 supported by suitable bearers of wrought or cast iron1 the ends of which are attached to 8snuggs0 cast on the purifier4 ,in large apparatus there are also pillars placed at intermediate distances to carry the weight of the sieves and purifying material4 ,the upper part of the purifier is surrounded by a cistern or reservoir of from #f inches to #bd inches deep1 and from #c inches to #f inches wide1 which is often cast with the purifier1 and forms part of it1 or at other times is attached thereto by bolts and cement1 and is for the purpose of containing water to seal the cover4 ,the cover of the purifier is of boiler plate or cast iron1 the latter being preferable on account of its durability2 but the increased weight is an impediment to its adoption4 ,the rim or border of the cover is rather deeper than the cistern into which it is placed1 and is effectually sealed by the water1 so preventing the gas escaping from that point4 ,often the purifier is divided into two compartments1 so that the gas ascends through a set of sieves on the one side1 and descends through another set on the other side1 answering the purpose of two sets of apparatus4 ,in all establishments1 however small they may be1 two distinct purifiers at least are necessary1 to enable the impure lime to be removed from the one whilst the gas is being purified by the other4 ,the next subject for consideration is that of the gasholders1 or vessels in which the gas is stored ready for delivery into the mains1 which distribute it throughout the districts to be lighted4 ,these vessels were originally termed gasometers1 which name is sometimes even now applied to them2 but as they have nothing whatever to do with the measurement of gas1 but are mere vessels of capacity or stores1 the simple name of gasholder is more expressive and appropriate4 ,the gasholder is composed of two distinct parts1 one of which contains water1 and is called the tank1 the other is the vessel which contains the gas1 being really the gasholder4 ,on the ,continent the former is very generally termed the 8cistern10 and the latter the 8bell40 ,the tank is a large cylindrical vessel1 constructed usually1 for the sake of economy1 of brickwork or masonry1 but when the ground is marshy1 or when water exists abundantly a short distance below the surface of the earth1 which would prevent the construction in masonry at a moderate price1 these tanks are made in cast-iron1 and1 indeed1 in small works1 are often of wrought iron4 ,in the interior of the tank there are two vertical pipes for the admission and egress of the gas1 called the inlet and outlet pipes2 the former being in direct communication with the manufacturing apparatus1 the latter with the mains which convey the gas to the town4 ,these pipes rise a few inches above the level of the top of the tank1 so that the water cannot overflow into them4 ,a series of columns1 generally of cast-iron1 but sometimes of wood1 or brick piers1 are placed at equal distances around the tank for the purpose of guiding the holder4 ,the holder is a cylindrical vessel closed at the top1 which is termed the roof1 and open at the bottom1 made of sheet iron1 varying in thickness according to the dimensions of the apparatus1 the smaller sizes being constructed of thin material in order to avoid an excess of pressure1 whilst those of very large dimensions are made of stout plates for the purpose of obtaining sufficient pressure to expel the gas to the burners4 ,the holder is somewhat less in diameter1 but of the same depth as the tank in which it is placed1 sometimes being partially suspended by chains which pass over grooved pulleys and counter-balance weights1 but more frequently only guided by rollers attached around its lower and upper edges1 which work against suitable guides in the tank and on the columns in such a manner as to permit the holder to ascend and descend in the tank with the greatest freedom4 ,the action of the gasholder is very simple4 ,the tank being filled with water1 and the holder immersed therein ready for use1 there is a space between the surface of the water and the roof of the holder2 the gas enters by the inlet pipe into this space1 and with the force it acquires in being expelled from the coal1 pressing on the surface of the water and underneath the roof1 and over the whole area of both1 causes the holder to rise4 ,thus1 by its own force or pressure1 the gas provides room for itself1 and in proportion to the quantity entering so does the holder rise out of the water4 ,for instance1 a holder having #ajj feet area1 or about #aa feet #d inches diameter1 in rising #aj feet will receive #a1jjj cubic feet of gas1 and in descending1 the same quantity would be expelled4 ,gasholders1 though often suspended1 are never entirely counter-balanced1 having always sufficient weight to give the necessary pressure for forcing the gas through the mains and smaller pipes to the burners1 all through the neighbourhood which is supplied from it4 ,the gasholder should be so constructed that1 when it is full or at its greatest height1 its lower edge will be so far under water as to prevent the gas from escaping4 ,the water in the tank serves three purposes2 it is the means of resistance for the gas to lift the holder1 it prevents the gas escaping or mixing with the atmosphere2 and it is the means of expelling or forcing out the gas as the holder descends4 ,,the ,,ironfounder4 ,illustration3 ,,foundry4 ,having already described the various operations of the trades employed in building and fitting a house1 we will say something of the manufacture of those cast iron columns1 girders1 gratings1 balconies1 pipes1 gutters1 air traps1 coal plates1 stoves1 and other articles which are so necessary to the ,builder before his work can be completed4 ,all these1 as well as a great variety of other goods made in black or bronze iron1 such as gates1 bridges1 pieces of furniture 7like umbrella stands71 iron taps1 and even pots and frying pans1 are made at the ,iron ,foundry4 ,iron is a metal of a bluish gray colour2 but in its pure state it looks almost white when polished1 and has a brilliant lustre1 while when it is broken the broken portion looks dull and fibrous4 ,it is the hardest of all the malleable and ductile metals1 and the most tenacious of all metals1 an iron wire of th of an inch in diameter bearing a weight of #fj pounds4 ,in the pure state it requires the strongest heat of what is called a wind furnace to melt it4 ,iron may be called the most precious of all metals2 it is certainly the most beneficial to man1 and its uses are innumerable2 indeed1 there is not a branch of human industry that could well afford to dispense with its aid and services2 nearly all the tools1 implements1 instruments1 and engines used by man are wholly or partly made of it1 and we could better afford to give up all the other metals than to part with this1 which is the most useful4 ,iron is used in two different states1 as cast iron and wrought iron1 the differences between them depending on the proportion of carbon combined with the metal1 cast iron containing the most and wrought iron the least4 ,for the production of wrought iron in the ordinary way1 two distinct sets of processes are required2 first the extraction of the metal from the 8ore0 that is brought up from the mine1 which metal is cast iron2 and secondly the conversion of this cast iron into malleable or bar iron1 by remelting1 puddling1 and forging4 ,bar iron is turned into steel by placing it in contact with charcoal in a peculiar kind of furnace4 ,when the ore is taken from the mine it is first burnt or calcined1 and then removed to a blast furnace to be smelted4 ,these blast furnaces are generally built of brick1 and look like small towers4 ,the ore is mixed with limestone1 which causes it to melt more easily1 and the fire is lighted with pit coal or coke4 ,the melted metal sinks to the bottom of the furnace in consequence of its weight1 while the limestone and dross float on the top1 and are allowed to run off when they cool into a mass of what is called 8slag40 ,the melted metal is run off from the bottom of the furnace1 either into moulds for some sort of castings1 or into a large furrow made in a bed of sand4 ,this large furrow has several smaller furrows on each side of it1 and has received the name of the 8sow20 the smaller furrows being called 8pigs20--and the iron when it is formed in this shape to be afterwards made malleable is called 8pig iron40 ,the pig iron is taken to other and smaller furnaces called puddling furnaces1 the bottoms of which are lined with clay mixed with the slag just mentioned1 and forming a substance which the puddlers call 8bull-dog10 though it would be difficult to discover why it received that name4 ,about four hundred weight of the pigs is placed in the furnace1 and as it melts the puddler stands at the furnace mouth with a long iron rod bent at the end1 and stirs it about1 until it comes to resemble several great balls of iron paste4 ,these balls are removed1 and fall into iron trucks pushed along a small railway by boys1 who wheel them at once to the 8shingling hammer10 an immensely powerful hammer worked by steam1 and this beats the iron into small square bars called 8blooms40 ,the blooms are next carried to the rolling mill1 which is a pair of great rollers cut into grooves of various sizes1 and between these grooves the bars are squeezed1 as the rollers turn round1 until they become much longer and narrower1 when they are known as 8forged bars40 ,some of the rolling mills1 however1 are plain cylinders without grooves1 and when a slab of white-hot iron is placed between these it comes out from the pressure in a great broad sheet of metal4 ,these operations require great bodily strength as well as considerable skill on the part of the workmen1 who are obliged to seize the heated metal with long tongs1 and to catch it in the same way as it comes out from the mill4 ,illustration3 ,casting ,ladle4 ,the iron which is intended for castings is melted in a 8cupola furnace10 so called on account of the dome-like shape in which it is built1 which has something to do with the more perfect heating of the metal4 ,when the iron is completely melted so that it will run freely1 the lower portion of the furnace is opened1 and the white-hot stream is received in the casting ladle1 or1 where it has to be carried for some distance1 and the casting is large1 in great iron pails carried in a sort of frame by two men4 ,from the casting ladle it is at once poured into the mould4 ,illustration3 ,mould4 ,small ,casting ,ladle4 ,the mould is a sort of iron box filled with a peculiar sort of sand1 into which a wooden pattern of the intended casting is pressed1 and the sand firmly rammed down and made solid4 ,there are1 in fact1 two boxes of sand1 each of which is impressed with one half of the thickness of the required casting1 so that when they are brought together1 and firmly fastened with the pins1 as shown in the picture1 the patterns which have been taken out have left a half of the impression in each box1 each corresponding exactly to the other4 ,a hole in the box receives the melted metal1 for which a channel has been left in the sand1 that it may freely run into the hollows left by the pattern1 and completely fill them2 then1 when it has sufficiently cooled1 the casting is removed1 and when the rough edges have been removed1 and the irregularities trimmed off1 it is ready for use1 and may be fitted to its other parts1 which have perhaps been separately cast1 as in the case of garden seats1 fenders1 chandeliers1 umbrella stands1 or ornamental girders and columns4 ,illustration3 ,furnace ,iron4 ,brush4 ,trowel4 ,bellows4 ,foot ,rule4 ,level4 ,shovel4 ,spatera4 ,hammer4 ,mould ,weight4 ,rammer4 ,we have only described solid castings1 but as ornamental iron work is generally made hollow1 this has to be cast in rather a different way1 though the only difference is that what are called 8cores0 are used4 ,these cores are in fact solid metal patterns made a little smaller than the hollow left by the real pattern1 and allowed to remain in the mould4 ,the melted iron then flows between the surface of the core and the surface of the mould1 and the casting is hollow1 so that when the core is removed the metal is only the thickness of the space left between the two surfaces4 ,you will see what is meant by placing a small teacup inside a larger one1 and then pouring water between them4 ,the tools used by the ,ironfounder are not very numerous3 the casting ladles and mould have already been mentioned2 the uses of the shovel and the mould weight1 the rammer1 and the furnace iron need no description4 ,the designers1 and pattern makers1 and the mould maker have the most important duties1 and the latter will have to use a small trowel and a spatera for arranging his sand and loam1 a level that it may be perfectly true1 and a brush and a pair of bellows for removing any particles of grit from the surface of the channels where the pattern has been impressed4 ,almost all irons are improved by admixture with others1 and1 therefore1 when superior castings are required they should not be run direct from the smelting furnace1 but the metal should be remelted in a cupola furnace1 which gives the opportunity of suiting the quality of the iron to its intended use4 ,thus1 for delicate ornamental work1 a soft and very fluid iron will be required1 whilst for girders and castings exposed to cross strain the metal will require to be harder and more tenacious4 ,for bed-plates and castings which have merely to sustain a compressing force1 the chief point to be attended to is the hardness of the metal4 ,castings should be allowed to remain in the sand until cool1 as the quality of the metal is greatly injured by the rapid and irregular cooling which takes place from exposure to air if removed from the moulds in a red hot state1 which is sometimes done in small foundries to economise room4 ,illustration ,,the ,,blacksmith4 ,illustration3 ,,forge4 ,in the building and fitting of the house a large portion of the iron work will have to be furnished by the ,smith1 and as we have already given some description of iron founding1 it will be necessary to say something about the ,blacksmith1 or the worker in iron or black metal1 whose business is different from that of the whitesmith1 which has to do more particularly with white or yellow metal4 ,the way in which malleable iron1 that is1 iron fit for the hammer1 is produced has been mentioned in connexion with the trade of the iron founder1 who in fact supplies the ,blacksmith with the raw material4 ,it is not very easy to tell you much about the way in which the ,blacksmith makes the great variety of articles which his trade furnishes1 for there is no business the success of which depends more upon personal skill4 ,as the trade of the ,smith1 or at all events the worker in metal1 is one of the most ancient1 and existed in times when there were few tools1--as1 in fact1 it is the ,smith who has to make tools1--so at the present day1 he has to depend chiefly on his own ability in the use of the hammer and a few other simple instruments to fashion the articles that come out of his workshop4 ,it is he who supplies the various articles of wrought iron work used in a building2 as pileshoes1 straps1 screw bolts1 dog-irons1 chimney-bars1 gratings1 and wrought-iron railings and balustrades for staircases4 ,wrought iron was formerly much used for many purposes for which cast iron is now generally employed2 the improvements made in casting during the present century having caused a great alteration in this respect4 ,it is not only for building purposes that the ,blacksmith is employed1 however1 since there is scarcely anything constructed of iron in which his aid is not required1 from important portions of machinery to the rough horse-shoes which have to be finished and fitted by the farrier4 ,in the forge1 where the great bellows suspended to the ceiling make the furnace roar1 and the sparks fly1 the clinking of hammers is heard all day long4 ,illustration3 ,hammer4 ,sledge ,hammer4 ,set ,hammers4 ,vice4 ,anvil4 ,tongs4 ,file4 ,the anvil1 on which the iron is beaten into shape1 the bench1 fitted with a vice for holding such portions of the work as require the file1 the tongs1 with which the red hot metal is held1 the sledge hammer1 and the set hammers1 are the principal tools4 ,illustration3 ,callipers4 ,compasses4 ,heading ,tools4 ,gauges4 ,square4 ,bottom ,tool4 ,the sledge hammer is used for beating the metal until it is tempered and easily formed into shape1 and it is in the tempering of the metal by beating that the great skill of the ,smith is often displayed4 ,the set hammers are used for setting out the work1 and have heads of different shapes1 according to the form which the metal is required to assume4 ,the various gauges are placed upon the anvil for the similar purpose of shaping the work1 and the callipers1 compasses1 and square1 measuring and adjusting it4 ,the heading tools consist of cutting1 punching1 and stamping instruments1 and are probably so called1 because they are furnished with heads to receive the blows of the heavy hammer1 by which they are forced into the hot metal on the anvil4 ,illustration3 ,double ,hooks4 ,punch4 ,slice4 ,fire ,irons4 ,these heading tools are held1 not by handles of their own1 which would break off with the concussion of the hammer1 but by a sort of withe of birch1 or some other tree fastened loosely round them at their heads1 and bound by a ring to keep them from parting4 ,the punch is used in making bolts or rivets1 the slice and fire irons for arranging the fuel in the furnace1 and removing small articles after they are heated1 the double hooks for removing or suspending bars1 and for some other purposes4 ,,the ,,brassfounder4 ,illustration3 ,casting4 ,next to iron1 perhaps brass is the metal chiefly employed in the manufacture of articles of daily use1 and the trade of the ,brassfounder is therefore of very great importance1 especially in connexion with the small metal fittings1 such as catches1 locks1 bolts1 hooks1 screws1 and other objects used in completing and furnishing the house4 ,brass is not a pure metal1 but is what is called an alloy1 that is1 a mixture of various metals4 ,it is composed of copper and zinc in such proportions as may be necessary to obtain various degrees of hardness and colour1 according to the use for which the compound is to be employed4 ,the best proportions for common brass are about two parts of copper to one part of zinc4 ,formerly brass was made by heating copper with calamine 7which is the ore of zinc7 and charcoal1 but it is now formed from melting the two metals together4 ,it is then cast into plates1 which are either broken up for recasting into any required form1 or rolled into sheets4 ,common brass is very malleable1 is more easily melted than copper1 and may be cast into any form4 ,it will take a very high polish1 does not rust or tarnish by exposure to the air1 and1 although it is durable in wear1 is sufficiently soft to yield readily to the file and other tools used by the workmen4 ,these properties make it useful for a great variety of purposes where steel or iron could not be so well employed4 ,illustration3 ,crucible4 ,magnet4 ,the smelting or mixing houses where the brass is made are fitted with air furnaces1 and in some of the best workshops the crucibles or melting pots are made of plumbago or pure blacklead1 which1 although it is more expensive1 is much more durable than the ,stourbridge clay1 of which the commoner crucibles are formed4 ,a very fine quality of brass for best castings consists of three parts of best selected copper1 and two of spelter1 with some best scrap brass and a little tin2 while a second quality is formed of two parts of ordinary copper and one part of spelter1 melted into ingots with a proportion of scrap brass and brass filings4 ,before the latter are used the iron filings are separated from them by a magnet1 or by a series of magnets fastened to a revolving chain frame4 ,the sheet brass is procured from the mills where it is rolled1 and the brass wire is also supplied from the special manufactories where it is drawn ready for use4 ,illustration3 ,making ,moulds4 ,the method of making moulds for casting iron has already been mentioned1 and those employed by the ,brassfounder are quite similar1 the tools used by the mould maker being the trowel1 mallet1 rule1 and sand hook1 the shovel for removing the sand1 the brush for sweeping the surface1 the bellows for blowing off the dust1 and the compasses for measuring accurately4 ,illustration3 ,brush4 ,sand ,hook4 ,compasses4 ,bellows4 ,shovel4 ,rule4 ,trowel4 ,mallet4 ,the principal materials for making foundry moulds for brass castings are fine sand and loam mixed in various proportions1 according to the nature of the work4 ,new sand is used for fine castings1 old sand for ordinary work4 ,the requisite external support is given by a couple of shallow rectangular iron frames without tops or bottoms1 called flasks or casting boxes4 ,the two halves constituting a casting box carry ears corresponding exactly with one another1 one set pierced with holes1 the other furnished with points entering truly into these holes1 and which may be made fast in them by cross-pins or wedges4 ,one of the flasks is laid face downward on a board longer and wider than it1 and is then rammed full of moulding sand2 the surface is struck off level with a straight metal bar or scraper1 a little loose sand is sprinkled upon it1 and another board of proper size placed over it and rubbed down close4 ,the two boards and the flask contained between them are turned over and the top board is taken off2 the clean surface of moist sand now exposed is dusted over with perfectly dry fine parting sand1 or very fine red brickdust4 ,the patterns or models are now properly arranged on the surface of the same1 the cylindrical or thick parts being partly sunk in the latter1 and care being also taken to leave sufficient space between the several patterns to prevent one part breaking into the other1 and also passages or ingates1 by which to pour in the metal and allow the air to escape4 ,the patterns are arranged on both sides a central passage or runner1 technically called a ridge1 from which again small lateral passages are made1 leading into every section of the mould4 ,the general surface is then properly arranged with the aid of small trowels1 and a little fine parting sand or brickdust is shaken over it4 ,when this has been accomplished1 the upper part of the flask is fitted to the lower by the pins1 and then also rammed full of mould sand4 ,the fine dry parting sand or brickdust serves to prevent the two halves from sticking together4 ,a board is now placed on the top of the upper half1 and struck smartly in different places with a mallet1 after which the upper half and its board are lifted up very gently and quite level1 and then turned over1 so that the upper half rests inverted on its board4 ,the models are next removed1 and channels scooped out from the cavities left by them to the hollows or pouring holes 7ingates7 at the end of the flask4 ,solid cores of sand or metal are adjusted in the proper places when the article is required to be cast hollow 7brass cocks1 for instance71 and also iron rails intended to have brass heads cast on them1 or such other articles of iron as are required to be solidly united with the brass4 ,the faces of both halves are now finally dusted with waste flour or meal dust2 the two halves are then replaced upon each other1 and the box is fixed together by screw clamps4 ,the moulds for fine castings 7articles with ornamental surfaces1 as screens1 sconces1 bell-levers1 c47 are faced with various fine substances1 such as charcoal1 loamstone1 rottenstone1 c4 that they may retain a sharp impression2 after which they are most carefully dried4 ,for ordinary work it is generally considered better that the sand should retain a little moisture1 though great care must be taken in this respect1 to guard against the danger of explosion4 ,illustration3 ,braces4 ,set ,moulds4 ,cores4 ,the mould then is a square frame1 mostly of iron1 filled with peculiar dark red sand1 which is pressed into a firm mass1 in which the patterns of the casting are imbedded and their perfect shape impressed4 ,the casters work at a large trough filled with the sand1 and the workshop1 with its forge1 has some resemblance to a bakehouse where black bread is being kneaded into loaves4 ,the first mould is made for what is called the 8odd side0 of the pattern--that is to say 7in solid castings71 the lower1 or inferior side--and this serves as a sort of pattern to which the moulder refers in fine castings4 ,the pattern being lifted off or out as soon as the sand-mould is sufficiently solid1 the whole surface1 in which the chasing of the pattern is clearly defined1 is dusted with bean-floor or pounded 8pot0 first1 and afterwards with loam1 sand1 charcoal1 or coal-dust4 ,this has the effect of making a smooth surface1 and effectually filling the interstices in the sand1 so as to prevent any raggedness in the casting4 ,each mould1 or rather the two sides of the mould1 are then placed near the surface and slightly baked1 a channel having been made in the edge of each for conducting the melted metal to the pattern4 ,the two sides are then placed together and held firmly by their pins and sockets1 and the mould is ready for the casting4 ,the 8pots10 or crucibles of greyish clay1 which turn red by the action of the fire1 are in the furnaces like so many tall flower-pots4 ,the dirty yellowish brass ingots1 made on the premises at a large mixing furnace1 having been first placed across the tops of the pots1 that they may expand before being melted1 are about twenty minutes afterwards reduced to a molten mass1 above which hovers a light sea-green flame mingled with streaks of brilliant colour1 like the water from a dyehouse2 meanwhile the moulds have been placed in a slanting position1 with the opening in the side upwards1 against a bank of sand or brickwork1 and everything is prepared for pouring4 ,a man1 who should be strong in the wrist1 stands on the furnace1 which has the openings at the top1 like a ,french cooking-stove1 and taking off the brick covers from the square aperture1 whence rushes out a tongue of green flame1 lifts out the pot with a pair of tongs1 and after the dross is removed by the skimmer or grunter1 hands it to the pourer1 who fills each mould in succession4 ,the fumes which rise from the midst of the coloured fire are peculiar and penetrating1 and the zinc eliminated from the molten brass falls in a metallic snowstorm1 its flaky particles adhering to everything with which they come in contact1 while the resistance of the sand to the metal causes a series of reports like muffled pistol-shots4 ,illustration3 ,large ,tongs4 ,small ,tongs4 ,pot ,holes4 ,skimmer4 ,grunter4 ,the brass cocks and plugs used in gas-fittings are all cast in one central stem1 like cherries on a stick1 their hollow forms being secured by means of cores made of hardened sand placed in the shape impressed in the mould4 ,these are broken off the central stem with a pair of pincers immediately after casting4 ,the ornamental 8vases0 and larger ornaments which form the body of ordinary gas chandeliers and lamps are formed out of thin metal by a process called 8stamping out10 the plates of metal being placed on a hollow die1 upon which a heavy hammer1 or rather weight1 is brought down1 being released from a latch and worked by the foot4 ,the depth of the casting would make so heavy a blow necessary that there would be danger of splitting the metal1 an accident which is prevented by the introduction of a leaden shape and a layer of clay1 which is decreased after each blow of the hammer until the proper depth is gradually secured without injury4 ,the process called 8reversing0 is an operation which secures a hollow casting1 the inner or hollow side being called the 8reverse40 ,for this purpose a mould is made from one in wax1 and the impression in the mould hardened1 so that another model can be taken from it4 ,this enables the moulder to secure a core which fits the impression in the mould1 as one cup would stand inside another2 and between the mould containing the sunk pattern and that with the projecting core there are placed strips of black clay1 to secure sufficient thickness of metal1 by not allowing the hollow to be too accurately filled4 ,the pattern when cast is 8laid out0 on a hollow hemisphere of iron filled with pitch1 and the irregularities of the casting removed by hand tools1 files1 rasps1 and knives4 ,in the case of figures1 such as cupids1 c4 forming ornaments for candelabra1 the various limbs have often to be modelled in separate 8cores10 which are afterwards baked hard1 and put together like a puzzle-map1 imbedded in the sand of the mould previous to casting4 ,this requires great skill to effect successfully1 and an experienced 8reverser0 is a man of mark in the factory4 ,illustration3 ,fork4 ,vent ,wire4 ,sleeking ,tool4 ,rasp4 ,file4 ,vice4 ,pincers4 ,hammer4 ,double-headed ,knife4 ,saw4 ,drawing ,knife4 ,knife4 ,the completed castings are now removed to the chasing-room1 where we may watch the gradual process of beautifying to which they are subjected1 and the sharpening of the ornamental details by means of tool and graver1 in a similar way to the first rough 8laying-out10 which removes the irregularities of the pattern4 ,the arms and branches which form a part of the gas chandelier work1 as well as many of the scroll-work ornaments1 are cast in halves1 which are taken to the soldering-room1 where a workman1 seated at a forge-like furnace1 heats them in the burning embers1 and applies to the edges the solder1 with which is mingled a flux of borax and water to secure its melting4 ,the heat is increased by a blowpipe1 which is in reality a double or jacketed tube1 the inner one supplying gas1 and the outer being connected with a large pair of bellows1 and mixing atmospheric air with the lighted gas at the point of combustion4 ,the pickling room is a large shed-like place filled with tubs1 troughs1 and earthen pans4 ,into one of these1 containing diluted aqua-fortis1 the metal is plunged for the purpose of removing the scale produced on the surface by the action of the fire2 from this it is dipped in a stronger solution1 to undergo the process called 8fizzing10 and its final baptism in pure acid restores the beautiful primrose colour which properly belongs to it4 ,it is still dull1 however1 and goes to be 8scratched10 an operation effected by means of a revolving wire-brush1 turned by a wheel and treadle1 and kept continually wet with water4 ,the ornamental processes have next to be considered1 and these are many4 ,previous to burnishing1 the work is dipped in argot or tartar 7the lees of wine-casks steeped in water71 so that it may be subject to a strong antioxyde4 ,the burnishing itself produces those bright veins and ornamental surfaces so often seen in brass work1 and is effected by fixing the work in a vice1 and rubbing the parts of the pattern which are to be brightened with a steel tool having a smooth bevel edge4 ,after being treated with ox-gall1 bean flour1 and acid1 to remove any still adhering grease1 the work is dried1 by being first dipped in hot water and afterwards buried in a pan of warm sawdust4 ,then there is lacquering1 both black and white1 a simple process enough1 since the lacquer is laid on with a brush1 and the work dried on a warm plate4 ,much of the work of the ,brassfounder1 as far as regards these latter operations1 is of course effected by machinery1 but the casting itself is entirely completed by the skill of the workmen4 ,illustration ,,the ,,gilder4 ,illustration3 ,a ,gilder's ,workshop4 ,when once the house is built and the work of bricklayer1 carpenter1 plumber1 painter1 glazier1 and mason is finished1 it is necessary to set about those decorations which accompany the furnishing2 and one of the first of the trades needed for this purpose is that of the ,gilder1 who has to do not only with cornices1 mouldings and other ornaments1 but also with the frames of pictures and looking-glasses that adorn the walls and chimney-pieces4 ,these frames1 however1 have first to be made by the joiner1 and then receive the work of the carver1 or the ornament maker4 ,the joiner does little more than put the plain groundwork of the frame together2 but the duty of the carver is of a very artistic description2 and to be a good carver in wood requires an education and a taste very nearly equal to that of the sculptor1 with whom the artists in wood formerly held a high rank4 ,most of the ornaments now used for frames1 however1 are less expensive than those formerly produced by the carver who added a fresh value to the painting or the looking-glass by exercising his skill upon the costly settings in which they appeared4 ,composition ornaments are now in general demand for all but the most expensive frames1 and as this composition--which is formed of glue1 water1 linseed oil1 resin1 and whiting--is pressed into moulds when it is of about the consistence of dough1 it is evident that the mould maker has partially taken the carver's place4 ,a new substance1 however1 has to a great extent superseded the old composition1 and this is papier-mch1 or the pulp of paper 7literally1 mashed or beaten paper71 which1 from its lightness1 its greater strength and durability1 and the thinness to which ornaments made of it can be reduced1 is preferable for all large decorations4 ,whatever may be the size or pattern of the frame1 however1 we will suppose that the ornament maker received it from the joiner1 who puts it together after it has been covered with coatings of hot size and whiting2 the size being made from parchment cuttings or kid leather parings boiled to a sort of jelly4 ,the nail or screw holes are then filled up with putty by the help of the putty knife1 and the surface of the frame smoothed with pieces of pumice stone4 ,the ornament maker next fixes on the decorations and hands it to the ,gilder1 whose first business is to wash the ornaments carefully in order to remove any oil that may have remained on their surface from the inside of the cast4 ,illustration3 ,size4 ,whiting4 ,putty ,knife4 ,badger ,tool4 ,duster4 ,gold ,leaf ,knife4 ,cushion4 ,tip4 ,the principal tools required by the ,gilder are1 first3 the cushion1 which is a flat board covered with several layers of woollen or flannel and afterwards with a piece of leather1 which is stretched tightly over it and nailed down to the edges1 thus forming a firm but soft and elastic bed4 ,a rim of parchment carried round one end of the cushion serves to hold the gold leaf4 ,second3 a gold leaf knife--which is a straight smooth-edged instrument1 not very sharp1 but carefully pointed at the end4 ,third3 the tip--a tool generally made of two pieces of card or very thin board glued together and holding between them a row of camel's hairs4 ,it is also necessary to have a badger tool and a duster2 the first for removing the loose edges and flying scraps of gold leaf1 after the gilding is completed1 and the latter for brushing away dust from the frame4 ,illustration3 ,miniature ,burnisher4 ,burnisher4 ,no4 #a4 ,burnisher4 ,no4 #b4 ,burnisher4 ,no4 #c4 ,chisel4 ,putter-down4 ,gold ,leaf ,box4 ,the burnishers are pieces of smooth stone 7flint or agate7 set in handles1 and are used for rubbing some parts of the gold1 when it is set on the frame1 until it attains a brilliant polish and smoothness of surface3 the bright gold portions of a frame being known as burnish1 and the dull parts or 8dead gold0 as matt4 ,a chisel and knife are necessary for removing any inequalities or overflowings of size from the edge of the frame2 the feather duster is used to dust the new gilding before it is sent home2 the size pot is the vessel in which the size is melted1 and the pan receives it before it is laid on4 ,the putter-down is a large soft brush used for pressing down the gold into the ornaments1 and removing the ragged edges of the gold-leaf from those parts of the frame where it is most difficult to place it smoothly4 ,illustration3 ,feather ,duster4 ,size ,pot4 ,pan4 ,gold ,book4 ,the gold box is of course a receptacle for the gold leaf1 and as the leaf is sent from the gold beaters in sheets placed between leaves of paper sewn together like a volume1 this is naturally called the gold book4 ,having received his frame1 then1 the ,gilder first gives it two or three coatings of 8thin white10 which is the name by which the size and whiting is known in the trade4 ,if any part of the frame is to be burnished1 it afterwards receives a coat or two of rather thicker size4 ,when these are dry1 strong warm size is laid on with a brush2 this is called clear cole1 and produces a smooth glossy surface1 which prevents the oil gold size from sinking through4 ,oil gold size is the next coating given to the frame1 and it is made of ochre and boiled linseed oil1 ground up together into a smooth creamy liquid1 which is thinned with more boiled linseed oil1 and put on very carefully with a soft brush4 ,in a few hours1 after the oil gold size is put on1 it is sufficiently dry to receive the gold leaf2 the surface being then slightly sticky1 so that it will hold it firmly and without its own surface being disturbed4 ,illustration3 ,pipkin4 ,rule4 ,gold ,size ,pot4 ,the ,gilder now commences the most important part of his work by taking the cushion on his left hand1 with his thumb through a loop which is attached to the bottom of the leather2 between the fingers of the same hand he places the tools that he will have to use1--namely1 the tip1 the gold knife1 and the camel-hair pencil4 ,he then takes a gold book and carefully blows out a leaf at a time on to the cushion1 until he has eight or ten leaves all heaped together within the rim of parchment which holds them from flying away4 ,this is a very delicate operation1 since if he should blow too hard the leaves would be carried all over the room4 ,he next separates one of the leaves from the rest with his knife1 and without cutting or tearing it lays it down smoothly upon the front part of the cushion1 partly by a gentle use of the knife itself1 and partly by skilfully blowing upon it4 ,then taking the tip in his right-hand he carefully presses it on the leaf1 to which it adheres1 and by this means transfers it to that part of the frame where he is at work4 ,where the ornaments are very deep1 the same part is gilt three or four times over1 and the gold is sometimes pressed in with a wad of cotton4 ,illustration3 ,skewing ,brush4 ,small ,pencil4 ,after the whole surface is carefully skewed1 or gone over with the brush which removes the ragged edges and still further presses the gold into the ornaments1 the frame is well dusted with another soft brush1 and then sized with clear size1 after which the work is complete4 ,supposing however that any part of the frame is to be of burnished gilt1 the clear cole and the oil gold size must not be suffered to touch that portion1--burnish gold size1 a substance made of grease1 clay1 black lead1 red chalk1 and bullock's blood1 is used instead of the oil gold size4 ,several coats of this are laid on the part to be burnished1 each being allowed to dry1 and perfectly smoothed1 before the other is applied4 ,the surface is then washed with a sponge and clean water1 another coating of gold size is laid on1 the gold leaf is applied1 and the burnishing tools used to impart the required lustre4 ,,the ,,cabinet ,,maker ,,and ,,upholsterer4 ,illustration3 ,,cabinet ,,maker',s ,,shop4 ,the trades of the ,carpenter and the ,joiner having been considered1 we may now turn to that of the ,cabinet ,maker1 who1 though he makes the furniture of the house1 and seldom has anything to do with building or fitting the house itself1 uses many of the same tools as the joiner4 ,illustration3 ,panel ,plane4 ,veneer ,plane4 ,smoothing ,plane4 ,floats4 ,rebate ,plane4 ,hand ,saw4 ,rebate ,plane4 ,as the ,cabinet ,maker mostly works in more costly woods1 and the operations of his trade have to be performed with greater nicety1 his implements are generally of rather a better sort2 while he has to fashion the articles in which he deals in so many different shapes that some of his tools1 such as planes and gouges1 are constructed especially for him1 like the panel plane1 used as its name implies in smoothing and forming the edges of panels for wardrobes1 chiffoniers1 and other pieces of furniture before they are placed in their frames1 and the veneer plane1 intended for putting on veneers1 or the thin slabs of costly wood with which more common woods are frequently covered4 ,the smoothing plane and the rebate plane1 as well as the hand saw1 the tenon saw1 the gimlet1 and the rule and square1 have already been mentioned in connexion with the joiner's business4 ,then there are moulding planes1 with their blades shaped hollow so that they will cut a strip of wood into a rounded form1 or shaped round so as to cut a hollow groove4 ,illustration3 ,square4 ,hand ,saw4 ,gimlet4 ,rule4 ,sometimes boards are joined at the edges by a process called match boarding3 a groove being made along the edge of one board while the edge of another is cut with a tongue along the middle to fit accurately into the groove4 ,for this purpose a pair of match planes are used1 one of which makes the groove and the other the tongue exactly of the proper size to fit perfectly4 ,this kind of joint is used for common doors1 which it is not worth while to frame together in panels4 ,the boards after being matched are nailed close together to strong cross-pieces4 ,the operations of mortising and dovetailing have been described in the description of joiner's work4 ,the various fittings and joints used in making chairs1 couches1 tables1 cabinets1 side-boards1 and other furniture are adaptations of the same kind1 or differ only according to the shape and position of the various parts4 ,in ornamental cabinet work the separate parts1 such as pillars1 legs1 arms1 and other pieces1 are often supplied by the turner and the wood carver1 who sometimes carry out their designs under the direction of the ,cabinet ,maker4 ,mahogany and many other of the harder woods are difficult to work1 as the grain does not all run the same way1 so that in planing them the wood is likely to split or chip where it should be shaved off smoothly4 ,to remedy this inconvenience1 the ,cabinet ,maker's planes are furnished with double irons1 that is1 an iron with a flat dull edge is screwed on to the face of the cutting iron1 so as to prevent the shavings chipping against the grain4 ,the more cross-grained the wood is the closer the workman brings down the dull iron towards the edge of the sharp one1 and his shavings are consequently finer4 ,the veneering plane is about the same size as the smoothing plane1 but the iron instead of having a smooth edge is toothed like a fine saw1 so that1 instead of taking off shavings1 it makes scratches all along the grain of the wood4 ,this is applied to the veneer as well as to the wood to which the veneer is to be glued1 so that the glue may easily hold the two rough surfaces together4 ,illustration3 ,tool ,chest4 ,previous to the veneer being put on1 the work is well warmed before a fire1 and the glue brush worked freely over both the veneer and wood to which it is to be applied4 ,when the veneer is put on1 it is rubbed backward and forward1 at the same time being pressed down with the hands until it sticks in the right place4 ,there are often lumps here and there where there is too much glue1 and these are remedied by the veneering hammer1 the head of which is made of wood furnished with a strip of iron plate4 ,this strip is laid flat on the veneer1 and the head of the hammer pressed with the hand while it is worked about by the handle1 pressing out the glue as it moves towards the edge4 ,when a piece of furniture is too large to be covered with one veneer1 these thin slabs of wood are laid on in several pieces1 the edges being first planed quite straight and made to meet with the greatest accuracy4 ,the whole surface is afterwards worked with the toothing plane1 and then scraped with a flat square piece of steel1 which takes off a wonderfully fine thin shaving and leaves the surface perfectly smooth4 ,it is afterwards finished with sandpaper4 ,it is then ,french polished with a liquid composed mostly of rectified spirits of wine1 gum1 shellac1 gum seed lac1 and ,venice turpentine1 the furniture being previously well oiled that it may better receive this sort of varnish4 ,clamps are a sort of screw vice for holding the various parts of the work4 ,the bow saw is a small fine blade of steel notched like a saw1 and fixed to a short handle1 from which a wooden or metal bow extends to the other end of the blade4 ,the bow keeps the saw from buckling or breaking1 and the tool is used for small work1 like the fretwork in front of pianos1 where a corner has to be turned and the piece sawn out4 ,the screws seen in the larger picture hanging above the ,cabinet ,maker's bench are used for holding pieces together after being glued1 or on other occasions4 ,illustration3 ,bow ,saw4 ,clamps4 ,it is supposed that there are about #ej1jjj workers in wood in ,london1 and #cej1jjj in all ,england4 ,about #afj1jjj timber trees of average size are required to make the furniture for the new houses built every year in ,england and ,wales4 ,in cabinet making there are many departments1 such as the chair maker1 the bedstead maker1 the carver1 the general manufacturer of tables1 drawers1 side-boards1 wardrobes1 c4 and the fancy ,cabinet ,maker1 who uses costly woods and makes workboxes1 desks1 dressing-cases1 and similar articles4 ,a good set of ,cabinet ,maker's tools is worth from #cj to #dj4 ,the ,upholsterer1 whose trade is generally joined to that of the master ,cabinet ,maker1 does what is called the 8soft work10 that is1 he undertakes the curtains1 hangings1 cushions1 carpets1 beds1 and the stuffing of the seats of chairs4 ,for these operations he requires but few tools4 ,illustration3 ,upholsterer's ,shop4 ,illustration3 ,devil4 ,strainer4 ,web ,strainer4 ,bench ,screw4 ,square4 ,the devil is the ugly and very absurd name given to a machine consisting of a box1 inside which a spiked wheel turns2 the use of this implement is to separate and tear to pieces such woven substances as1 when reduced to shreds1 serve for the stuffing of furniture1 as also to soften and make finer hemp or tow for the same purpose1 when horsehair1 which is the best and most expensive material1 is not used4 ,cocoa-nut fibre is now sometimes applied for this purpose2 and in the commonest furniture hay is frequently placed as a foundation1 with a small quantity of horsehair on the top4 ,the bench screw is a kind of vice which will hold a very thick substance1 like the seat of a chair or sofa1 without injuring the woodwork2 the web strainer is used for stretching strong cross-pieces of webbing across the bottom of the seats of chairs or couches1 to make a firm foundation for the stuffing to rest upon1 and with the ordinary strainer to bring the canvas cover that confines the stuffing tightly and firmly to its place1 an operation which requires great care1 especially when metal springs are placed beneath the horsehair to make the seat more elastic4 ,the ,upholsterer's hammer is of such a shape that it will drive a small nail deeply down in a space when it is hidden by the damask or leather covering of the furniture4 ,the punches are for a similar purpose2 while the needle and the regulator are used in stuffing the seats and properly adjusting the hair or other material4 ,illustration3 ,upholsterer's ,hammers4 ,punches4 ,float4 ,screwdriver4 ,needle4 ,regulator4 ,bradawl4 ,,floor-,,cloth ,,manufacturer4 ,illustration3 ,,drying ,,warehouse4 ,the trade of manufacturing floor-cloth may be said to be connected with the furnishing of the house1 since this very useful covering for the floors of halls and passages is now in almost universal use4 ,floor-cloth is generally made in large factories built for the purpose1 since considerable space is required1 not only for preparing1 painting1 and putting the pattern upon the cloth1 but also for drying it when it is finished1 the great lengths in which it is made rendering it necessary to hang it from a great height1 in order that it may dry without the paint being damaged 7see drying warehouse74 ,the smell of the paint and other substances also makes it desirable to have the factory well ventilated1 and situated at some distance from dwelling-houses4 ,the cloth is made partly of hemp and partly of flax1 the former being the cheaper of the two1 but the latter being fitted to retain the oil and paint on the surface without allowing it so easily to sink or soak through4 ,in order to avoid the necessity for seams or joinings in the cloth1 looms are constructed expressly for weaving canvas of the greatest width likely to be required4 ,when the pieces of cloth are taken to the floor-cloth factories1 they are generally either #ajj yards long and #f yards wide1 #ajh yards long and #g yards wide1 or #aac yards long and #h yards wide4 ,the flax and hemp are spun and the canvas woven principally in ,scotland1 in the town of ,dundee4 ,illustration3 ,shears4 ,cutting ,knife4 ,the canvas is cut into pieces 7see cutting knife and shears71 varying from #fj to #ajj feet long1 and each of these pieces is stretched over a frame in a vertical position1 most factories having a large number of such frames1 some often #ajj feet long by #ah or #bj feet high1 and others of smaller dimensions4 ,a wash of melted size is applied by means of a brush to each surface2 and while this is wet the surface is well rubbed with a flat piece of pumice stone1 by which the little irregularities of the canvas are worn down1 and a foundation is laid for the oil and colour afterwards to be applied4 ,the preparation of japanned cottons1 which are used for table covers1 or what is known as 8oil-cloth10 is very similar4 ,the paint employed for floor-cloth consists of the same mineral colours as that used in house painting1 and is mixed with linseed oil in the same way2 but it is very much thicker and stiffer in consistence1 and has very little turpentine added to it4 ,the canvas receives several coatings on the back as well as on the front1 and is well dried and smoothed at intervals4 ,illustration3 ,blocks4 ,the finished ,pattern4 ,pattern for ,floor ,cloth4 ,back of ,printing ,block4 ,illustration3 ,preparing ,japanned ,cottons4 ,the pattern is placed on by means of wooden blocks1 on the first of which the rudiments1 or ground work1 of the design is cut1 and on the rest other portions of the pattern1 so that1 as they are covered with paint and applied to the cloth by the workman1 the pattern is gradually printed1 and appears in the different colours which are successively applied to each block4 ,illustration3 ,printing ,floor ,cloth4 ,the blocks are made of pear-tree wood on one side and of deal on the other1 the pear-tree wood being more easily engraved with the pattern4 ,the blocks 7which we will suppose to be four for one pattern--red1 yellow1 blue1 and green7 being ready1 and the prepared canvas spread out on a flat table1 the printing commences4 ,the paint 7say red7 is applied with a brush to the surface of a pad or cushion formed of flannel covered with floor cloth2 the block held by a handle at the back is placed face downwards on this cushion1 and the layer of paint thus obtained on the surface of the block is printed on the canvas by pressing the block smartly down upon the surface of the latter4 ,a second impression is made in the same way1 by the side of and close to the first1 until the whole surface of the canvas is printed over with the pattern of this first block1 which is generally about #ae inches square4 ,then the second block is applied1 and adds a little more to the pattern in another colour2 the third follows1 adding still more2 and then the fourth1 which completes the printing4 ,illustration3 ,trowel4 ,claw4 ,scrubbing ,brush4 ,palette ,knife4 ,paint ,brushes4 ,roughing ,comb4 ,hammer4 ,the trowel and palette knife spreading and mixing the paint1 the roughing comb for patterns where the grain of wood is imitated1 and the pots1 cans1 and jars1 for the colours1 are the principal tools besides those already described4 ,,the ,,paper ,,stainer4 ,illustration3 ,,printing ,,press4 ,the trade of the ,paper ,stainer has grown to be one of considerable importance1 and this is not to be wondered at when we consider how much the art of paper staining has increased the means of decorating our houses1 by hanging the walls with elegant patterns printed in beautiful colours1 instead of leaving them of one dull uniform hue1 or a bare surface of wood and plaster4 ,in old times the walls of rooms were either of panelled wood1 sometimes carved and polished1 or were hung with tapestry made with the needle1 or with woven silk1 cotton1 or linen1 but the former was extremely costly1 and the latter neither cleanly nor healthy4 ,the trade of the ,paper ,stainer has to a great extent superseded both1 and the interior walls of houses are now seldom formed entirely of wood1 since they are intended to be covered with various qualities of paper hangings4 ,illustration3 ,front of ,printing ,block4 ,back of ,wooden ,block for ,printing4 ,the mode of printing or painting a pattern on large sheets of paper has now been in use for nearly two hundred years1 although1 of course1 improved methods are at present employed4 ,there are three modes of producing the pattern on paper hangings4 #ast4 ,wooden blocks are carved with the outlines of the figures only in relief2 with these the paper is printed1 and the pattern is afterwards finished by hand painting with a pencil4 ,this mode is slow and too expensive for ordinary use4 #b;dly4 ,a sheet of leather1 tin1 or copper1 is cut with holes in the required pattern1 and a brush dipped in colour is worked over the sheet after it is laid upon the paper1 so that the paint goes through the holes1 and leaves the pattern in colour4 ,this is called stencilling1 and is only employed for very common hangings4 ,the third process consists of carving a wood block for each of the colours used in the pattern1 and printing the paper by almost exactly the same method as that employed for printing floor-cloth1 an operation which has already been described4 ,illustration3 ,crutch4 ,ladle4 ,hand ,brush4 ,spat4 ,paint ,brushes4 ,the paper is printed in pieces twelve yards long4 ,a piece is laid out on a long bench and the ground colour applied1 consisting of whiting tinted with some sort of pigment and liquefied with melted size4 ,this is laid on with large brushes4 ,when the paper is dry it is ready to receive the print at the printing press1 where the blocks are pressed upon it by a sort of weighted arm which comes down from above the centre of the bench4 ,there must generally be as many blocks as there are colours in the pattern4 ,illustration3 ,colour ,sieve4 ,paint ,pot4 ,colour ,drum4 ,size ,can4 ,some paper hangings have a glossy or satin ground4 ,to produce this a ground of satin white1 properly tinted1 is laid on2 this ground is then rubbed with powdered ,french chalk1 and worked with a brush till a gloss is produced4 ,sometimes these papers are passed between heated rollers which have been engraved with a sort of pattern1 and this produces a pattern without any additional colour1 like that of figured or watered silk4 ,flock papers are those in which part of the pattern resembles cloth4 ,to produce this the pattern is printed1 not in paint1 but in size1 and then the paper being passed through the flock drum1 the flock 7which is composed of fragments of woollen cloth7 adheres to the pattern4 ,illustration3 ,drum for laying on ,flock4 ,striped hangings are sometimes produced by the paper being quickly passed on a roller beneath a trough1 the colour in which flows through a number of parallel slits in the bottom2 and occasionally various coloured stripes are obtained by dividing the trough into cells1 with one cell and one slit for each colour4 ,some papers1 in order to bear washing or cleaning1 are printed with colours mixed with oil or varnish instead of size4 ,illustration3 ,paper ,staining ,machine4 ,,the ,,calico ,,printer4 ,illustration3 ,,cylinder ,,printing ,,machine4 ,the trade of the ,calico ,printer may be said to be one of the most important in this country1 since we export such immense quantities of cotton prints to our various colonies1 as well as to other countries in the world1 that this business forms a very considerable part of ,british commerce4 ,calicoes1 muslins1 c4 intended for printing must first have the fibres removed from their surface by the operation of the singeing machine2 which consists of a half-cylinder of iron or copper laid horizontally1 and kept at a bright heat by a range of gas-flames or a furnace2 over this half-cylinder the length of cloth is drawn with a steady motion till the down or fibre is singed off4 ,illustration3 ,bowking ,kiers4 ,the next process is that of bleaching1 because the whiter the cotton cloth becomes1 the more light it will reflect from the surface1 and the more brilliant the colour of the dyes will appear4 ,the principal chemical substance used for bleaching cotton is chloride of lime1 which is known as bleaching powder2 but there are several processes employed in its application1 as well as various methods which are adopted by different manufacturers to increase its effects by mechanical contrivances1 the application of heat1 or otherwise4 ,illustration3 ,dash ,wheel4 ,the first operation of bleaching1 however1 and that which immediately follows singeing1 is boiling the cloth in an alkaline bath consisting of a solution of soda4 ,for this purpose a bowking apparatus is used4 ,this machine 7see cut7 is1 in fact1 a large cauldron1 with a flat false bottom to protect the cloth from being scorched by the fire beneath4 ,through the centre of this false bottom a vertical pipe rises from near the real bottom to a height above the top of the cauldron1 and carries a conical cap like an umbrella above its open end at top4 ,when the liquid in the cauldron begins to boil thoroughly the steam forces a constant stream of liquid up the pipe1 which stream is scattered by forcing against the umbrella-shaped cap1 and so falls with some force back on to the cotton in the cauldron4 ,when this process has continued long enough1 the liquor is allowed to cool1 and the cotton is taken to be rinsed at the dash wheel1 where it is subjected to the free action of water1 or to a rinsing machine1 so constructed that the web travels on rollers1 and is thoroughly washed during its course4 ,illustration3 ,wringing ,machine4 ,the simplest and earliest method of imprinting figures upon calico is by means of a wooden block1 upon the face of which the design is cut in relief1 as in an ordinary wood-cut4 ,the block is of sycamore1 holly1 or pear-tree wood1 or more commonly of deal1 faced with one of these woods4 ,the block varies in size from nine to twelve inches long1 and from four to seven inches broad1 and it is furnished on the back with a strong handle4 ,when the design is complicated1 and a very distinct impression is required1 the figure is sometimes formed by the insertion of narrow slips of flattened copper wire1 the space between being filled with felt4 ,illustration3 ,face of ,block for ,calico ,printing4 ,back of ,calico ,block4 ,the printing block1 which is worked by hand1 is charged with colour by pressing it gently upon a piece of superfine woollen cloth called the sieve1 stretched tightly over a wooden drum1 which floats in a tub full of size or thick varnish to give it elasticity1 so that every part of the raised device may acquire a sufficient coating of colour4 ,the sieve is kept uniformly covered with the colouring matter by a boy or girl called the tearer1 who takes up with a brush a small quantity of the colour contained in a small pot1 and distributes it uniformly over the surface2 for if this were not done1 the block would take up the colour unequally4 ,the printing shop is a long well-lighted apartment1 the air of which is kept warm for the purpose of drying the cloth as it is printed2 to insure which it is passed over hanging rollers1 so as to expose a large surface to the air4 ,the printing table1 which is about six feet long1 is made of some well seasoned hard wood1 such as mahogany1 or of marble1 or flag-stone1 the object being to present a perfectly flat hard surface4 ,this table is covered with a blanket1 upon which the calico is extended1 and the block1 being charged with colour1 is applied to its surface1 a blow being given with a wooden mallet to transfer the impression fully to the cloth4 ,it is necessary1 of course1 to join the different parts of the design with precision1 and in doing so the printer is guided by small pins at the corners of the block4 ,thus1 by repeated applications of the block to the woollen cloth and to the calico alternately1 the whole length of calico is printed4 ,illustration3 ,drying ,room4 ,by this method1 a single block prints only one colour1 so that1 if the design contain three or more colours1 three or more blocks will be required1 all of equal size1 the raised parts in each corresponding with the depressed parts in all the others2 in order1 therefore1 to print a piece of cloth twenty-eight yards long1 and thirty inches broad1 with three blocks1 each measuring nine inches by five1 no less than #fgb applications of each1 or #b1jaf applications of the three blocks1 are necessary4 ,thus it will be seen that printing by hand is a tedious operation1 requiring more diligence than skill4 ,illustration3 ,brush4 ,when the design1 however1 consists of straight parallel stripes of different colours1 they may be applied by one block at a single impression4 ,for this purpose the colours are contained in as many small tin troughs as there are colours to be printed4 ,these troughs are arranged in a line1 and a small portion of each colour is transferred from them to the woollen cloth by a kind of wire-brush4 ,the colour is distributed evenly in stripes over the surface of the sieve by a wooden roller covered with woollen cloth4 ,for the rainbow style1 as a peculiar pattern is called1 the colours are blended into one another at their edges by a brush or rubber4 ,an important improvement has been made in the construction of hand-blocks1 by the application of a stereotype plate as the printing surface4 ,a small mould is produced from a model of the pattern1 and the stereotype copies are then made by pouring mixed metal into it4 ,a number of the stereotype plates are then formed into a printing block1 by being arranged in a stout piece of wood4 ,illustration3 ,one of the ,cylinders of the ,machine1 showing the way by which it is coloured4 ,the greatest mechanical improvement in the art of calico printing was the invention of the cylinder or roller printing at the end of the last century4 ,this style of printing has been generally adopted in ,lancashire1 and is the cause of the success of the ,english over the continental printers4 ,one cylinder machine1 attended by one man to regulate the rollers1 is capable of printing as many pieces as one hundred men and one hundred girls could print with hand blocks in the same time4 ,a mile length of calico can be printed off with four different colours in a single hour4 ,this cylinder machine consists of a hollow cylinder or roller of copper1 about three feet long and three or four inches in diameter1 the pattern on which has been produced by the pressure of a mill1 on which the design has been originally stamped by the pressure of a hard steel roller which has been engraved4 ,the copper cylinders are mounted on a strong iron shaft with a toothed wheel at its end1 in order to put it in train with the rotatory printing machine for one1 two1 or more colours4 ,on a roller at the upper part of this apparatus are wound the calico webs stitched together1 the end of which is brought between the engraved copper cylinder and a large centre roller covered with blankets1 against which it is made to bear with a regular pressure4 ,the engraved cylinder turns on the top of another cylinder covered with woollen cloth1 which revolves at the same time as the former1 while its under part dips in an oblong trough containing the dyeing matter1 which is of a pasty consistence4 ,the engraved cylinder is in this way supplied with plenty of printing colour1 and is cleared from the superfluity by the thin edge of a blade made of bronze1 called the doctor1 which is applied to it as it turns1 and gently scrapes the surface4 ,after this the cylinder acts upon the calico1 which receives the impression of the pattern in colour1 and rolls onward at a great rate of speed4 ,there are various kinds of colours or dye stuffs used in calico printing1 some of which impart fast colours by themselves1 and others which require the web to be first prepared in order that they may become fixed4 ,in almost all the modes of calico printing the processes are very numerous to ensure the beauty and permanence of the colours4 ,in what is called the steam colour printing1 the agency of steam is applied to aid in fixing the colours to the cloth4 ,the cloth is first steeped in a mordant or fixing liquor1 then printed by the cylinder in various colours1 called steam colours4 ,it is then hung up to dry1 and is afterwards exposed to the action of steam by means of various apparatus1 which are adapted to the particular effect intended1 to be produced in fixing the dye4 ,the designs for calico printing are very expensive1 and such a constant succession of new patterns are demanded1 that some of the ,lancashire printers expend several thousands a year on designing and engraving alone4 ,illustration ,,the ,,tinman4 ,illustration3 ,,workshop4 ,tin is never found existing in an uncombined or native state4 ,tin ore occurs most abundantly in ,cornwall and ,devon1 the mines of these counties having been celebrated for this metal from very ancient times4 ,the district in ,cornwall where tin mines are most abundant is termed the 8,stannaries40 ,the ,prince of ,wales for the time being derives a large income from the mines1 and is termed ,lord ,warden of the ,stannaries4 ,the word 8,stannaries0 is derived from the ,latin stannum1 tin4 ,the amount of tin ore annually obtained from the ,cornwall and ,devon mines amounts to #aa1jjj tons1 which1 at the average value of #fc per ton1 is worth #fic1jjj4 ,this ore yields about #g1jjj tons of the metal1 having an average value of #aai per ton4 ,about four-fifths of all the tin raised in the world is produced in these mines4 ,the ore is a heavy1 hard1 brittle1 and usually dark brown mineral1 which occurs chiefly in granular masses of various sizes4 ,these grains are obtained in mines1 where they occur in veins mixed with other minerals1 and also from the beds of streams1 where they have been washed out of the soil by the action of running water4 ,in the former case they are termed tin stone2 in the latter stream-tin4 ,tin is obtained from the ore by first breaking up the latter1 whilst a current of water flows over it and carries off the impurities1 which are lighter1 and therefore more readily borne away than the heavier tin ore4 ,after being thus freed from the admixture of other minerals1 the ore is usually roasted or burned1 to drive off any traces of sulphur it may contain2 it is afterwards heated to redness with blind coal or culm1 and a small portion of lime1 when the melted metal separates from the dross1 and runs into cavities prepared for its reception4 ,it is afterwards refined by being remelted1 and other impurities separated1 which either sink or float on the surface4 ,the purest metal is yielded by the ore called stream-tin1 which is smelted with charcoal instead of coal4 ,if a block of tin thus obtained is heated slightly1 and then allowed to fall from a height1 it separates into a number of prisms which adhere together in pyramidal masses4 ,in this state it is termed grain-tin4 ,tin is a silvery-white metal possessed of a high degree of metallic lustre4 ,it is sufficiently soft to be cut with a knife1 and may be readily bent1 when it gives out a peculiar crackling noise2 if repeatedly bent and straightened1 it becomes hot from the friction of its particles with one another1 and ultimately breaks4 ,it is inelastic and moderately ductile1 but very malleable1 the thickness of tin-foil being about one thousandth part of an inch4 ,it has but little tenacity1 a wire of one-tenth of an inch in diameter not being able to support a heavier weight than #di lbs4 ,tin is the most easily melted of all the common metals1 and it possesses the valuable property of not rusting when exposed at ordinary temperatures to the conjoined action of air and water1 or even to weak vegetable acids4 ,tin1 in a pure state1 is seldom employed2 but in combination with other metals it is a substance of great value4 ,its most important uses depend on its power of resisting the action of air and moisture2 it is therefore largely employed for protecting the surfaces of copper and iron1 that rust so readily4 ,tin plate1 or more properly tinned plate1 which is so largely employed in the manufacture of saucepans1 coffee-pots1 tea-kettles1 c4 by the tinman is not1 as its ordinary name seems to imply1 made of tin1 but is formed of the best sheet iron1 rolled out to the required thickness1 and coated on each side with a layer of tin4 ,copper vessels ought to be invariably tinned inside1 to prevent the rusting of the copper by the action of acids4 ,tinfoil is largely employed for the purpose of preserving moist articles from becoming dry1 and is used instead of paper for enclosing fancy soap1 chocolate1 and other substances of a similar nature4 ,it is also extensively used in the manufacture of looking-glasses1 and is sometimes placed behind paper-hangings to exclude the damp of the walls4 ,the most important alloys into the composition of which tin enters are bronze1 pewter1 bell-metal1 and solder4 ,tin dissolved in acids is largely employed by dyers in fixing or rendering permanent various colours used in dyeing4 ,the preparation termed putty powder is a rust of tin1 obtained by exposing the melted metal to the air2 it is employed in polishing metals and other articles4 ,illustration3 ,mallet4 ,soldering ,iron4 ,hammer4 ,block ,hammer4 ,the tinning of the inner surfaces of cooking utensils and other vessels of capacity is effected by scouring the surface until it is perfectly bright and clean2 then heating the vessel1 pouring in some melted tin and rolling it about1 and rubbing the tin all over the surface with a piece of cloth or a handful of tow2 powdered rosin is used to prevent the formation of oxide4 ,bridle bits1 stirrups1 and many other small articles1 are tinned by immersing them in fluid tin4 ,tin-plate working1 or the forming sheets of tinned iron into a variety of useful vessels and utensils1 is carried on by means of bench and hand shears1 mallets1 and hammers1 steel heads and wooden blocks1 soldering irons and swages4 ,in the formation of a vessel1 the first operation is to cut the plate to the proper size and form with shears1 and1 when the dimensions of the article require it1 to join them together1 which is done either by simply laying the edge of one plate over that of the other1 and then soldering them together1 or by folding the edges together with laps and then soldering them4 ,similar joints are required when gores or other pieces are to be inserted1 and also at the junction by which a cylinder is closed in4 ,the usual method of forming laps1 bends1 or folds1 for this or other purposes1 is to lay the plate over the edge of the bench and to bend it by repeated strokes with a hammer2 but a machine is sometimes used for this purpose4 ,illustration3 ,straight ,snips4 ,scotch ,snips4 ,large ,shears4 ,bent ,snips4 ,after a tin vessel has been rounded upon a block or mandril by striking it with a wooden mallet1 and the seams finished1 all its exterior edges are strengthened by bending a thick iron wire into the proper form1 applying it to what would otherwise be the raw edges of the metal1 and dexterously folding them over it with a hammer4 ,illustration3 ,two-handed ,wrench4 ,soldering ,pile4 ,pudding ,stake4 ,punches4 ,hatchet ,stake4 ,tongs4 ,a superior kind of tin ware1 commonly known as block tin ware1 is carefully finished by beating or planishing with a polished steel hammer upon a metal stake4 ,the process of swaging is resorted to as a ready means of producing grooved or ridged borders1 or other embossed ornaments4 ,this process consists in striking the metal between two steel dies or swages1 the faces of which bear the desired pattern1 and are made counterparts of each other4 ,many ornamental articles are produced by embossing or stamping tin plate1 in the same manner as other metallic sheets1 with a fly-press or other machinery4 ,cheap coffin-plates are manufactured at ,birmingham in this way2 and these and similar articles are sometimes lacquered1 painted1 or japanned4 ,tin forms the principal ingredients in various kinds of pewter and other white-metal alloys1 which are manufactured into domestic utensils by casting1 stamping1 and other processes4 ,illustration3 ,chisels4 ,charcoal ,stove4 ,polishing ,anvil4 ,britannia metal is a mixture of tin1 antimony1 copper1 and brass1 which is melted1 cast into slabs1 and rolled into sheets4 ,the principal use of this metal is for candlesticks1 teapots1 coffee-biggins1 and other vessels for containing liquids4 ,the feet of candlesticks1 the bodies of teapots1 and other articles containing embossed work1 are stamped between dies2 while articles of a more globular shape are stamped in two or more pieces1 and afterwards soldered together4 ,the sheet metal has a ductility which enables it to be bent into various curved forms by pressure on a model or core3 this process is called spinning4 ,illustration3 ,funnel ,stake4 ,punches4 ,horse4 ,punches4 ,bick ,irons4 ,crease ,iron4 ,many small vessels1 spoons1 and other articles1 are cast in an alloy somewhat harder than that which is rolled into sheets4 ,most of the tools employed by the ,tinman are the irons1 stakes1 and bickers1 on which the tin is hammered into proper shape1 with shears for cutting1 the punches for piercing holes1 and the soldering iron and charcoal stove for making joints4 ,illustration ,,the ,,farrier4 ,illustration3 ,,farrier',s ,,shed4 ,when we remember how usefully horses are employed for our advantage1 how generously and willingly they work1 and how docile and obedient they are when properly treated1 we shall begin to see that the trade of the ,farrier is one which should be studied very carefully1 and that nobody should follow the business who has not become tolerably skilful4 ,the ,farrier who shoes the horses1 is very often consulted when those animals are ill1 so that he should have some knowledge of simple remedies in cases when the veterinary surgeon lives at a distance1 or is out of the way4 ,especially the ,farrier should thoroughly understand the construction of the horse's hoof1 which1 hard and simple as it may look1 is very delicate1 and is composed of several important parts4 ,one thing should never be forgotten in shoeing a horse1--first that1 although the hoof is a hard horny covering1 it has an inside portion which is very tender and liable to be hurt2 and secondly1 that the hoof itself expands as the weight of the horse presses upon it4 ,illustration3 ,anvil4 ,stool4 ,staple4 ,pointing ,stake4 ,punch4 ,shoe4 ,illustration3 ,nippers4 ,drawing ,knife4 ,rasp4 ,buffer4 ,the ,farrier's shed is fitted with a forge1 or furnace where the iron is heated1 and in which the fire is blown to great heat by the huge bellows fastened above it2 it also contains an anvil1 on which the horseshoes are made or shaped1 a stool on which the ,farrier sometimes sits to examine a horse's hoof1 and staples and rings1 to which the horses' heads are fastened by halters during the process of shoeing4 ,when a horse is taken to be shod1 the ,farrier should begin by taking off one of the old shoes4 ,he first raises the clenches with a tool called the buffer and if the shoe does not then come off easily1 loosens some of the nails with the punch1 till it can be gently removed4 ,when the shoe is off he rasps the edge of the hoof all round1 and with the nippers or pincers takes out any stubs that may be left in the hoof4 ,he then pares the hard portions of the foot1 and this is an operation which requires great care and skill as well as a good deal of practice in the use of the drawing knife4 ,the ,farrier must always remember the state of the roads when he is paring the horse's feet1 for if the roads are dry and stony he must take off very little of the horn1 or the foot will be bruised4 ,illustration3 ,fulter4 ,damper4 ,slice4 ,pretchel4 ,swage4 ,tongs4 ,turning ,hammer4 ,the horseshoes are frequently purchased by the ,farrier of the ,blacksmith who makes them1 but some ,farriers are also ,smiths1 and both make and fit the horseshoes4 ,in either case the ,farrier keeps a stock of rough shoes which he alters at the time that they are wanted1 so that they may fit the horse1 and one of the first things to be done is to make the groove all round the shoe1 and drill the holes in it for the nails4 ,this groove1 in which the heads of the nails sink1 is called the 8fuller10 and the tool with which it is made is also called the 8fuller10 or 8fulter40 ,having cut off the ends or heels of the shoe1 made the fuller1 and opened the nail holes1 the ,farrier next makes what is called the 8clip10 which means turning up the toe of the shoe1 to prevent its being forced back on the hoof4 ,in these parts of his work he has probably used the chisel1 turning hammer1 swage and pretchel1 while for the work at the forge he has had to employ the poker1 the tongs for holding the shoe on the anvil1 the slice for taking small things from the fire1 and the damper1 which is a wisp of wet straw held by wooden tongs for lessening the heat of the shoe during hammering4 ,he next begins to fit the shoe1 the horse being tied up to the staple in the wall of the shed4 ,the fitting of the shoe is an operation requiring the greatest care and attention1 and the good ,farrier will spare no pains to do his work perfectly1 as many a valuable horse has been ruined by an ill-fitting shoe4 ,when the shoe is fitted it is 8filed up10 by which all roughness is removed from the edges of the nail holes1 and the sharp edges of the shoe itself are taken off4 ,illustration3 ,nail4 ,nail ,bag4 ,shoeing ,hammer4 ,the ,farrier generally makes his own nails since they are of a peculiar shape1 and the heads should completely fill the nail holes1 that they may not allow the shoe to shift on the horse's hoof4 ,they are made from long rods of iron called nail rods1 and when finished are spread about the smithy to cool1 because when they are allowed to cool gradually they become harder1 and less liable to break4 ,if the nails are of a proper shape1 the holes straight through the shoe1 and the shoe fits the foot1 very little skill is required to nail it on1 and clench the ends of the nails to the hoof4 ,before the shoe is nailed on1 however1 it is usual1 when the horse has tender feet1 to cover the sole of the foot with leather1 gutta-percha1 or felt made waterproof1 8felt0 being made of woollen cloth torn to shreds which are then pressed together and formed into sheets4 ,in any case the ,farrier is expected to 8stop the foot10 that is1 to fill the hollow and tender portion of the foot within the shoe1 with tow or oakum dipped in tar4 ,illustration3 ,fleam4 ,stamp4 ,scissors4 ,ladle and ,spatula4 ,brush4 ,poker4 ,reaching ,iron4 ,the shoe is now nailed on1 and a good ,farrier will often be able to secure it with only five nails4 ,the hind shoes are of course different in shape to those which are placed on the fore feet1 and it is generally necessary to use seven nails to fix them on to the hoofs1 since the hind foot expands less than the fore1 and there is more drag upon it when the horse is in motion1 so that the shoe is more easily shifted4 ,the time at which a horse's shoes want removing depends on several causes4 ,if a horse wear out his shoes in less than a month they had better not be removed1 but whether the shoes are worn or not the horse's hoofs should be looked to by the ,farrier1 every three or four weeks1 as the hoofs sometimes outgrow the shoes1 and the shoes require refitting4 ,from what has been said about the ,farrier's business it will be seen that it is a most important one1 but besides the knowledge and experience required for the more mechanical part of his work1 he should also know something of the diseases and ailments of horses1 and be able to apply the proper remedies4 ,it is true that this part of the business belongs properly to the veterinary surgeon1 but the ,farrier should at all events understand what is proper to be done in any ordinary disorder or in cases of emergency4 ,he will of course know how to use the fleam when the animals require bleeding1 as they frequently do4 ,this instrument is a sort of knife1 the sharp part of which is the small spade-shaped pieces at the ends of the blades4 ,the ladle for melting the ingredients of ointment1 for sprains or swellings1 and the spatula for mixing it1 or for spreading and mixing the drugs for boluses or the large pills frequently given to horses1 are some of the instruments used in this part of the ,farrier's business4 ,,the ,,needle ,,maker4 ,illustration3 ,,grinding ,,needle ,,points4 ,there is perhaps no implement of greater importance than that smallest of all tools1 the needle1 and in all civilized countries the number of needles consumed is so great1 and such an enormous supply is required for the sewing of the clothes of mankind1 that the manufacture is one of the most remarkable in this country1 whence by far the greater part of the whole supply is derived4 ,it will only be proper in this place for the author to acknowledge his obligations to ,mr4 ,w4 ,b4 ,tegetmeier1 whose most useful little work on 8,common ,objects0 affords brief and reliable information on this as well as on many other interesting subjects4 ,the material from which needles are made is soft steel wire of the requisite degree of fineness4 ,this is obtained from the manufacturer in large coils1 each containing sufficient wire to form several thousand needles4 ,these coils are first cut up into pieces of the length required to make two needles1 usually about three inches1 large shears being used1 capable of cutting a coil of one hundred wires4 ,illustration3 ,shears4 ,needles placed in iron rings4 ,soft ,straight ,liner4 ,trowel for hardening4 ,five or six thousands of these lengths are made into a bundle kept together by a ring of steel at each end4 ,they are then heated to redness in a furnace1 and afterwards laid upon a flat iron plate1 and rubbed backwards and forwards with a steel bar until each wire is perfectly straight4 ,the next stage is to grind a point at each end of the wire4 ,this is done by the aid of grindstones about eighteen inches in diameter and four inches thick2 they are made to revolve so rapidly that they are liable to fly into pieces1 and are therefore partially enclosed in iron plates to avoid injury to the grinder1 should such an accident occur4 ,the grinder takes from fifty to sixty wires between the thumb and forefinger of his right hand2 and as he presses them against the stone1 he causes all the wires to roll round1 and thus each is ground to a point4 ,so expert do the grinders become by practice1 that they point a handful of these wires1 usually about sixty1 in half a minute1 or about seven thousand in an hour4 ,during the grinding every wire gives out a stream of sparks1 and these together form a bright glare of light4 ,illustration3 ,rubbing4 ,pointing these wires is the most unhealthy part of the manufacture2 the fine dust is carried into the lungs of the workmen1 and destroys them in a few years1 very few living beyond the age of forty4 ,wet grindstones cannot be used1 as the points of the needles would be rapidly rusted4 ,illustration3 ,drill for making the ,eyes4 ,smooth ,file for rubbing4 ,hammer4 ,cullender4 ,packet of ,needles4 ,flat ,file4 ,the wires thus pointed at each end are stamped by a heavy hammer1 raised by a lever moved by the workman's foot4 ,the under surface of this hammer is so formed1 that when it falls on the wire midway between the two ends it stamps on one side the gutters1 or grooves1 in which the eye is afterwards made2 and the anvil on which the wire rests when the hammer strikes it forms the two grooves on the opposite side4 ,this stamping also makes a slight depression or pit on each side at the spot intended for the eye4 ,the wires are then passed to a boy1 who takes a number of them in his left hand1 whilst with his right he works a press1 moving two hard steel points or piercers4 ,these come down upon the wire as it is placed beneath them1 and pierce the eyes for the two needles4 ,each wire now resembles two rough unpolished needles united together by their heads2 and as it would require much trouble to divide them separately into two needles1 a number are threaded upon two very thin wires1 and are separated by filing and bending4 ,illustration3 ,hand ,press for piercing the ,eyes4 ,stamping4 ,any needles which may have been bent in the several processes are straightened by rolling under a steel bar1 and are hardened by heating in a furnace1 and suddenly cooled in cold water or oil4 ,after hardening they are tempered by being slightly heated1 and if any are bent during hardening1 they are straightened by being hammered on anvils with small hammers2 finally1 the whole are polished by laying twenty or thirty thousand side by side upon a piece of thick canvas1 smearing them with oil and emery1 rolling up the canvas1 and rubbing them under a press for several hours or even days4 ,illustration3 ,soft ,straightening4 ,needles placed ready to be filed4 ,needles in different ,stages of ,manufacture4 ,drilled-eyed needles undergo another operation--a fine drill is made to revolve rapidly in the eye of each1 to take off the rough edge and to prevent their cutting the thread when used2 finally1 the points are finished on a revolving stone1 and polished on a wheel covered with leather1 and enclosed in a paper for sale4 ,simple as the construction of a needle may appear1 it has to pass through the hands of #abj workmen1 from the time it leaves the iron mine until the manufacture is completed4 ,the chief seat of the needle manufacture in this country is ,redditch1 in ,worcestershire1 where upwards of seventy millions are made weekly4 ,english needles are far superior to those of foreign manufacture4 ,illustration ,,the ,,calenderer ,,and ,,hotpresser4 ,illustration3 ,,mill4 ,the business of the ,calenderer and ,hotpresser in so many respects resembles part of that already described as preceding the printing of calico1 that only a brief notice of it will be necessary4 ,the singeing and bleaching of the cotton has been explained1 and calendering is the name generally applied in the manufacturing districts to the processes of smoothing1 dressing1 and glazing cotton and linen goods2 the object being either to prepare them for the operations of the calico printer1 or to impart the last finish to the goods before they are folded and packed for the market4 ,the earlier calenders1 or calendering machines1 closely resembled a common mangle in their action1 but were very large and heavy1 and worked by a horse-wheel or other sufficient power1 but the process was greatly improved by the invention of a machine in which the pressure is produced between rollers1 instead of between rollers and flat surfaces1 and in which consequently the alternating movement is got rid of1 and also it is easier to give a uniform and equal pressure4 ,illustration3 ,singeing ,cotton ,goods before ,calendering4 ,iron ,plate4 ,roller4 ,windlass4 ,scissors4 ,tongs4 ,illustration3 ,embossed ,roller for ,machine ,printing4 ,presses4 ,the rollers or cylinders were formerly made of wood2 they are now usually of paper or cast iron4 ,the paper cylinders are formed by packing a great number of circular pieces of stout pasteboard upon an iron axis1 and compressing them very tightly by means of iron bolts passed through them1 acting upon circular end-plates of cast iron4 ,the surface is brought to a perfectly even and polished state by turning in a lathe4 ,iron rollers are made hollow and when necessary heated from the inside4 ,when a glazed or polished surface is required on the goods to be calendered1 mechanism is employed to cause two adjacent rollers to revolve with different velocities1 so as to produce a rubbing action4 ,illustration3 ,printing ,press4 ,chair with ,rollers4 ,tin ,block4 ,the furnace for heating the rollers1 the chair with rollers1 the presses and tin blocks for hotpressing1 and the windlass for turning1 are easily understood in relation to this trade4 ,the printing press and embossed cylinder have been mentioned in the trade of calico printing4 ,the mill1 turned by a horse1 is used where steam power is not employed to put the machinery in motion4 ,illustration3 ,furnace4 ,,the ,,cutler ,,and ,,file-,,cutter4 ,illustration3 ,,grinding4 ,amongst all the trades that occupy the attention of mankind1 that of the ,cutler1 which also includes the tool maker1 is certainly one of the most essential1 since without tools no other manufactures could be carried on4 ,cutting instruments of various kinds have been in use from the earliest ages1 if for no other purposes1 for cutting food1 slaughtering animals1 and making war upon each other4 ,in ancient times1 as well as amongst some barbarous tribes at the present day1 these implements were frequently made of shells1 edged flints1 or hardened wood1 fashioned into sharp weapons2 at a late period1 cutting as well as warlike instruments were formed of brass or bronze2 but at the present time1 in all civilized nations they are formed exclusively of steel or iron4 ,steel is formed from the purest bar iron--that which comes from the ,swedish mines being preferred4 ,this is buried in powdered charcoal and heated to whiteness for several days1 without exposure to the air2 during this time the metal becomes much harder1 whiter in colour1 crystalline in texture1 and blistered on the surface4 ,the blistered steel so produced is prepared for use1 either by binding several bars together and hammering them into one1 or by melting them in earthenware pots1 called crucibles1 and pouring the melted metal into moulds of the size required4 ,in the latter state it is called cast steel4 ,cutlery is generally understood to comprise all kinds of knives1 razors1 lancets1 and edge tools1 including scythes1 saws1 scissors1 shears1 spades1 and many others2 and the manufacture of forks1 files1 and some other instruments not possessing cutting edges1 is frequently included in the business4 ,it will be impossible to give a detailed description of how all these are made1 so only two or three must be selected4 ,in a ,cutler's factory knife blades are forged from steel bars in a number of small rooms1 each containing a fireplace or hearth1 a trough to hold water1 and another trough for coke1 which is specially prepared for this kind of work2 there are also an anvil1 hammers1 and some other tools4 ,illustration3 ,cutler's ,hammers4 ,anvil4 ,two persons are engaged in each room1 one being called the maker or forger1 the other the striker4 ,the forger buries the end of the steel bar in the fire to the extent required2 and to determine when it should be removed requires some judgment1 since if it be overheated or 8burnt10 it will be quite unfit for cutting purposes4 ,on the other hand1 it must be sufficiently heated to acquire the proper degree of softness for the operation of shaping the blade from it4 ,when the end of the bar has been properly heated it is brought to the anvil1 where it is fashioned by the striker into the required shape by means of a few blows of the hammer4 ,this roughly shaped blade is then cut off from the end of the bar1 which is again heated for forming the next shape1 and so on to the end4 ,the cutting part of the blade thus rudely formed is next welded to a piece of iron1 which forms the bolster1 or shoulder1 that is1 the part that rises round the handle of the knife4 ,to make the shoulder of the size and shape required1 and to give it neatness and finish1 it is introduced into a die by the side of the anvil1 and a swage 7see ,blacksmith7 placed upon it1 to which a few smart blows in the proper direction are given by the striker4 ,illustration3 ,shoulder-iron4 ,the die and swage are called prints by the workpeople4 ,besides the bolster1 the part which fastens into the handle1 technically termed the tang1 is also shaped from the piece of iron welded on to the cutting part of the blade4 ,after the bolster and tang have been properly finished1 the blade is heated again1 and then well hammered on the anvil4 ,this operation1 which is termed smithing1 requires particular care and attention4 ,it is intended to consolidate the steel1 and to render it brighter4 ,the next process the blade has to undergo is that of marking4 ,this is done with a broad punch made of the very best and hardest steel1 and having the name and corporate or trade mark of the firm carved on the bottom end or point4 ,the blade is heated to a dull red 7worm-red1 as it is termed by the workmen71 and the mark cut in on one side of the blade with the punch by a single blow of the hammer4 ,now comes the most important process of all1 viz4 the hardening and tempering of the blades4 ,upon the effectual performance of these operations depends the practical value of the articles4 ,the ,sheffield workmen have justly and deservedly acquired the very highest reputation for peculiar skill in this most difficult department of the cutlery business4 ,the hardening of the blade is effected by heating it to bright redness1 then plunging it perpendicularly into cold water1 which operation renders it extremely hard1 but at the same time very brittle1 which is an inconvenience1 of course1 requiring to be remedied4 ,this is done by the process of tempering4 ,to this end1 the hardened blades are first rubbed with finely powdered sand1 to remove scales1 c4 from the surface2 they are then placed on an oblong tray made of steel1 and on this exposed to the fire until they acquire a bright blue tint4 ,the workman judges of the proper degree of tempering entirely by the colour1 and the utmost attention is bestowed upon this point to ensure the most perfect unanimity in this respect4 ,the hardened and tempered blades are then submitted to the manager's inspection1 who applies various tests to them1 and rejects any that may turn out imperfect in any one point4 ,the blades that have been examined and passed by the manager are next taken to the grinding mill1 or1 as it is technically termed1 the wheel4 ,each separate shop in the building in which the grinders work is called a hull4 ,the grinding is done on stones of various qualities and sizes1 according to the kind of articles to be ground4 ,the rough grit stones come mostly from ,wickersley1 near ,rotherham2 the finer and smoother grained stones1 and the so-called whitning stones1 come mostly from the more immediate neighbourhood of ,sheffield4 ,the blades of table-knives are ground on wet stones1 the grinding stone being suspended1 for that purpose1 in an iron trough filled with water to a sufficient height to make the surface of the fluid just touch the face of the stone4 ,the grinding stones1 as well as the glazers and polishers1 are turned by machinery worked by steam power4 ,a flat stick is used by the grinder to keep the blade pressed to the surface of the stone4 ,the ground blades are then glazed1 which simply means that a higher degree of lustre and smoothness is given them by grinding on a tool termed a glazer4 ,this consists of a wheel made of a number of pieces of wood1 put together in such a manner that the edge or face always presents the end way of the wood1 which is done to preserve the circular shape by preventing contraction of the parts4 ,the grinding face of the wheel is covered with so-called emery cake1 which consists of a composition of beeswax1 tallow1 and emery4 ,the glazing wheels have a diameter of four feet4 ,the tang of the blade is stuck into a temporary handle to facilitate the operation4 ,illustration3 ,grindstones4 ,chisel4 ,buskin4 ,flat ,file or ,rasp4 ,gauge4 ,the last process to which the blades of table-knives are subjected in the grinding mill is that of polishing2 this is done on circular pieces of wood covered with buff leather1 with a coat of finer emery 7flour emery7 composition upon it1 which are made to revolve with much less velocity than the grinding stones and the glazers4 ,the ground blades are again taken to the manager1 who applies several very severe tests to them1 to try their temper and edge4 ,illustration3 ,shears4 ,flat ,stick4 ,haft ,moulds4 ,knife-handles are made of horn1 ivory1 ebony1 silver1 ,german silver1 mother of pearl1 c4 ,two sorts of ivory are principally used1 the ,egyptian and the ,african2 the latter is the more beautiful and transparent of the two1 the ,egyptian looking more like horn4 ,the tusks are sawn in appropriate lengths1 which are then cut by a small circular saw into handles of the required size4 ,the handles are properly filed1 and occasionally also carved or fluted in different patterns4 ,a variety of files are used for these purposes1 such as flat files1 threading files1 hollow files1 half round files1 c4 ,the handle is then bored to receive the tang4 ,the bolster of the blade having been properly filed1 the tang is inserted into the bore1 and fixed in by cement in the usual way4 ,it is afterwards farther secured by a ,german silver pin passing through the handle and tang4 ,the silver and ,german silver handles are stamped in dies4 ,the mother of pearl handles are carved or fluted in different patterns4 ,illustration3 ,fire-irons4 ,crooked ,tongs4 ,tongs4 ,dies4 ,the knives thus finished by the hafter are now taken once more to the manager1 to undergo a final examination preparatory to their removal to the warehouse4 ,the forging of razors is performed by a foreman and striker in the same manner as in making the blades of table-knives4 ,the bars or rods as they come from the tilt and rolling mill are about half an inch broad1 and no thicker than is sufficient for the back of the razor4 ,the anvil on which the razor-blades are forged is rounded at the sides2 by dexterously working the blade on the rounded edge of the anvil1 a concave surface is given to the sides1 and the edge part thus made thinner1 which saves the grinder a deal of labour4 ,the blade having been cut off the bar1 the tang is formed by drawing out the steel4 ,the blade is then properly hardened and tempered4 ,the last and most important process which the razor-blade has to undergo is that of grinding4 ,the difference in the prices of blades1 make all of them of the same material1 is owing entirely to the circumstance that stones of much smaller diameter are used for grinding the higher priced blades1 and much more time and labour are given to the operation than is the case with the cheaper sorts4 ,in making a fork1 the end of a steel bar is first made red-hot2 it is hammered so as to give a rough approximation to the shape of the shank or tang2 it is again heated1 and a blow from a die or stamp gives the proper contour2 the prongs are cut out by a powerful blow from a stamp of peculiar form1 and the fork is finally annealed1 hardened1 ground1 and polished4 ,it is this process of fork grinding which has so often been made a subject for comment2 the fork is ground dry upon a stone wheel1 and the particles of steel and grit are constantly entering the lungs of the workmen1 thereby ruining the health and shortening the duration of life4 ,many contrivances have been devised for obviating this evil1 but the fork-grinders have not seconded these efforts so zealously as might have been expected4 ,in making pen and pocket-knives1 a slender rod of steel is heated at the end1 hammered to the form of a blade1 and carried through many subsequent processes4 ,but the putting together of these hinged knives requires more time than the making of the blades1 and affords a curious example of minute detail4 ,when the pieces of bone1 ivory1 pearl1 tortoise-shell1 horn1 or other substances1 which are to form the outer surface of the handle1 are roughly cut to shape2 when the blade has been forged and ground1 and when the steel for the spring is procured1 the whole are placed in the hand of a workman1 who proceeds to build up a clasp-knife from the little fragments placed at his disposal4 ,so many are the details to be attended to1 that a common two-bladed knife has to pass through his hands seventy or eighty times before it is finished4 ,a file1 as every one knows1 is a steel instrument1 having flat or curved surfaces so notched or serrated as to produce a series of fine teeth or cutting edges1 which are employed for the abrasion of metal1 ivory1 wood1 c4 ,steel for making files being required to be of unusual hardness1 is more highly converted than for other purposes1 and is sometimes said to be double converted4 ,small files are mostly made of cast steel4 ,the very large files called smiths' rubbers are generally forged immediately from the converted bars4 ,smaller files are forged from bars which are wrought to the required form and size by the action of tilt-hammers1 either from blistered bars or from ingots of cast steel4 ,these bars are cut into pieces suitable for making one file each1 which are heated in a forge-fire1 and then wrought to the required shape on an anvil by two men1 one of whom superintends the work while the other acts as general assistant4 ,the next operation upon the blanks which are to be converted into files is that of softening or lightening1 to render the steel capable of being cut with the toothing instruments4 ,this is effected by a gradual heating and a gradual cooling4 ,the surface is then rendered smooth1 either by filing or grinding4 ,illustration3 ,file ,cutting4 ,file ,cutting4 ,the cutting of the teeth is usually performed by workmen sitting astride upon a board or saddle-shaped seat in front of a bench1 upon which is fixed a kind of small anvil4 ,laying the blank file across the anvil1 the ,cutler secures it from moving by a strap which passes over each end and under his feet1 like the stirrup of the shoemaker4 ,he then takes in his left hand a very carefully ground chisel made of the best steel1 and in his right a peculiarly shaped hammer4 ,if the file be flat1 or have one or more flat surfaces1 the operator places the steel chisel upon it at a particular angle or inclination1 and with one blow of the hammer cuts an indentation or furrow completely across its face from side to side1 and then moves the chisel to the requisite positions for making similar and parallel cuts4 ,if it be a half round file1 as a straight-edged chisel is used1 a number of small cuts are necessary to extend across the file from edge to edge4 ,so minute are these cuts in some kinds of files1 that in one specimen about ten inches long1 flat on one side and round on the other1 there are more than #bj1jjj cuts1 each made with a separate blow from the hammer1 and the cutting tool being shifted after each blow4 ,the range of manufactures afford few more striking examples of the peculiar manual skill acquired by long practice4 ,several highly ingenious machines have been contrived for superseding the tedious operation of file cutting by hand2 but suited as the process may appear to be for the use of machinery1 it has been found to present such great difficulties1 that we believe no file-cutting engine has been brought successfully or extensively into operation4 ,one very serious difficulty arises from the fact that1 if one part of the file be either a little softer than the adjacent parts1 or a little narrower1 so as to present less resistance to the blow of the hammer1 a machine would1 owing to the perfect uniformity of its stroke1 make a deeper cut there than elsewhere4 ,after the files have been cut1 the steel is brought to a state of great hardness2 this is effected in various ways1 according to the purpose to which the file is to be applied2 they are generally coated with a sort of temporary varnish1 then heated in a stove1 and then suddenly quenched4 ,after hardening1 the files are scoured1 washed1 dried1 and tested4 ,it will be seen that the tools employed by the ,cutler are few1 and consist mostly of the hammers1 moulds1 dies1 anvils1 grinding stones1 and others already mentioned4 ,illustration ,,cotton ,,manufacturer4 ,illustration3 ,,carding4 ,the extremely valuable substance1 called ,cotton1 which is now raised in such abundance as to furnish the cheapest and most extensively-used clothing1 is produced in the seed vessels of the cotton plant1 of which there are many varieties2 some are herbaceous annual plants1 growing from eighteen to twenty-four inches high2 others1 shrubs about the size of our currant bushes1 and of from two to ten years' duration2 whilst a third kind attain the growth of small trees1 with a height of from twelve to twenty feet4 ,the leaves of the cotton plant are of a bright dark green colour1 deeply divided into five lobes2 the flowers are large and showy1 of a bright sulphur or lemon colour1 and closely resemble in appearance and botanical structure those of the single hollyhock2 each flower is succeeded by a triangular three-celled seed vessel1 which attains the size of a small walnut1 and when ripe bursts open from the swelling of the cotton contained in the three cells2 the seeds1 which are rather larger than those of grapes1 are inclosed in the cotton wool1 which adheres very firmly to them4 ,one variety of cotton1 cultivated in ,china1 and some parts of ,america1 has a yellow tint2 this tint it preserves when woven into the fabric called 8nankeen40 ,illustration3 ,cotton ,plant4 ,bale of ,cotton4 ,the cotton plant is largely cultivated in ,india1 ,china1 ,united ,states1 ,west ,indies1 on the shores of the ,mediterranean1 and1 in short1 in almost all the warmer parts of the world2 it flourishes readily in soils too poor for the growth of grain1 and other crops1 and succeeds perfectly well in dry seasons4 ,the cotton1 when perfectly ripe1 is gathered by women and children1 the seeds and wool being picked out of the pod2 it is dried in the sun1 and is then ready for the removal of the seeds4 ,in ,india this operation is performed by means of two parallel rollers1 which are fixed in a frame at a small distance apart1 so that when they are turned round the cotton is drawn through whilst the seeds1 which from their size are unable to pass1 are torn off and separated4 ,with this simple machine a man can separate the seeds from about fifty pounds of cotton in a day4 ,in ,america a still more rapid process is adopted3 the cotton is placed in a box1 one side of which is formed of stout parallel wires1 placed about one-eighth of an inch apart2 by the side of this box is a roller1 carrying a number of circular saws with curved teeth1 which project through the wires into the box4 ,on the roller being made to revolve1 the teeth of the saws drag the cotton through the wires1 the seeds remaining behind2 after being thus separated1 the cotton is powerfully compressed into bags1 and is ready for transport to this and other manufacturing countries4 ,the cotton is seldom unpacked until it arrives at the mill1 the purchases being all managed by samples4 ,when it is unpacked1 the first thing to be done is the sorting1 and in this much care and skill are required2 for the different bags furnish different qualities of cotton1 and it is necessary to produce yarn of uniform quality at the cheapest rate4 ,in order1 therefore1 to equalize the different qualities1 the contents of all the bags are mixed together in the following manner4 ,a space being cleared and marked out on the floor1 the cotton contained in the first bag is scattered over this space1 so as exactly to cover it2 the contents of the second bag are in like manner spread over the first1 and the cotton in all the other bags is disposed in a similar manner2 men and boys tread down the heap1 which is called a bing or bunker1 until at length it rises up in shape and dimensions very much like a haystack4 ,whenever a supply of cotton is taken from the bing it is torn down with a rake from top to bottom1 by which means it is evident the contents of the different bags are collected together in a mass of uniform quality and colour4 ,in mixing different qualities of cotton it is usual to bring together such only as have a similar length of staple4 ,a portion of the waste cotton of the mill is also mixed in the bing1 for making the lower qualities of yarn4 ,for higher numbers1 as well as for warps1 a finer quality of cotton must be selected2 and thus it will be seen that the formation of a bing is an important operation1 the quality of the goods produced depending upon it4 ,in this state the cotton contains sand1 dirt1 and other impurities1 and the fibres are matted together by the pressure they were subjected to in packing4 ,to open the fibres and get rid of the sand1 c4 the cotton is put into a machine called a willow4 ,this consists of a box or case1 containing a conical wooden beam1 studded over with iron spikes2 this beam is made to turn round five or six hundred times a minute4 ,the cotton1 as it is torn down from the bing1 is put in at one end of the machine1 where it is caught by the spikes1 tossed about with great violence1 and gradually driven forward to the other end4 ,the sand and other impurities fall out of the machine through an open grating at the bottom2 the dust and lighter matter pass off through a series of wire openings1 and the cleaned cotton is sent down a shoot into the room below4 ,if the cotton is of fine quality it is beaten1 or batted1 with hazel or holly twigs4 ,for this purpose1 it is spread on a frame1 the upper part of which is made of cords and is quite elastic4 ,a woman1 with a rod about three or four feet long in each hand1 beats the cotton with great violence1 and so entirely separates the fibre4 ,any loose impurities which remain fall out between the cords2 seeds and fragments of seed-pods1 which adhere to the cotton somewhat firmly1 are picked out by hand4 ,by this method the cotton is thoroughly opened1 and made quite clean1 without injuring the staple4 ,illustration3 ,opening the ,cotton4 ,the coarser qualities are passed at once from the willow to the scutching or blowing machine1 which does the work of batting1 only in a more violent manner1 and is therefore not adapted for fine qualities2 but in coarser spinning is in general use1 to prepare the cotton for the carding engine4 ,the cotton1 which is still in a confused and tangled state1 has now to be carded1 upon the regularity and perfection of which process depends much of the success of spinning1 and also the durability and beauty of the stuff to be woven4 ,a cotton card is a sort of brush1 containing wires instead of bristles4 ,the cards are made of bands or fillets of leather1 or are formed of alternate layers of cotton1 linen1 and india-rubber pierced with numerous holes1 in which are fixed bent pieces of iron wire1 called dents or teeth4 ,the fibres of the cotton are not yet sufficiently level to be twisted into yarn2 and it often happens that the teeth of the card lay hold of a fibre by the middle and thus double it together1 in which state it is unfit for spinning4 ,the cardings are therefore doubled and drawn out by a machine called a drawing frame1 the principle of which depends upon different pairs of rollers revolving with different degrees of rapidity4 ,if1 however1 the riband1 as it leaves the carding-engine1 were simply extended in length by drawing it out1 it would be liable to tear across1 or to be of a different thickness at different parts of its length4 ,to prevent the tearing and to equalize the thickness1 a number of cardings are joined together and drawn out to a length equal to the sum of the length of all the separate cardings4 ,the effect produced is the same as taking a piece of cotton wool between the finger and thumb and drawing it out many times1 laying the drawn filaments over each other1 before each drawing4 ,if the cotton be then examined it will be found that all the fibres are parallel and of equal length4 ,this effect is accomplished very perfectly in the drawing frame1 which consists of a number of rollers arranged in what are called heads1 each head consisting of three pairs of rollers1 of which the second pair moves with greater speed than the first1 and the third moves quicker than the second4 ,illustration3 ,drawing4 ,thread ,frame4 ,by the process of doubling and drawing1 the cotton is formed into a loose porous cord1 the fibres of which are arranged side by side4 ,this cord is still too thick for yarn1 but it cannot be reduced in size by drawing merely1 for if this were attempted it would break2 a slight twist is therefore given1 which by condensing the fibres allows the drawing to proceed4 ,this is the commencement of the spinning process 7which is1 in fact1 little more than a combination of drawing and twisting7 and is called roving4 ,illustration3 ,cotton ,bobbins4 ,buffaloes with ,bobbins4 ,roving4 ,the bobbin-and-fly frame is an exceedingly complicated machine1 although the objects to be accomplished by it are sufficiently simple2 namely1 to give the roving a slight twist1 and then to wind it on the bobbin4 ,the first is easily done by the revolutions of the spindle2 the second is more difficult4 ,it is scarcely necessary to explain that the bobbins now under notice differ in no way from the reels in common use1 except in being of very large size4 ,the spindle which holds the bobbin is a round steel rod1 driven by a small cog-wheel1 fastened on the lower part of the spindle4 ,the bobbin is slid upon the spindle1 and the small bed or platform on which it rests is made to revolve by another series of small wheels4 ,the spindle has two arms1 called the fly or flyer4 ,this fly is fixed on the top of the spindle in such a way that it can be taken off in an instant1 for the purpose of putting on or taking off the bobbin4 ,one arm of the fly is hollow1 the other solid1 and all this serves to balance the machinery4 ,one machine contains from thirty to a hundred and twenty spindles1 which1 for economy of space1 are placed in two rows1 each spindle in the back row standing opposite the space left between two spindles of the front row4 ,the action of the machine is this3--,the sliver having been drawn by the rollers1 is twisted by the rapid revolutions of the spindle into a soft cord or roving2 this enters a hole in the top of the spindle1 and passes down the hollow arm of the fly2 it is then twisted round a steel finger1 which winds it on the bobbin with a certain pressure4 ,illustration3 ,throstle4 ,flyer4 ,the throstle machine is usually made double1 a row of bobbins1 spindles1 c4 occupying each side of the frame4 ,the bobbins filled with rovings from the bobbin-and-fly frame1 are mounted at the upper part of the frame in two ranges4 ,the roving from each bobbin passes through three pairs of drawing rollers1 where it is stretched out to the requisite fineness4 ,on quitting the last pair of rollers1 each thread is guided by a little ring or a notch of smooth glass1 let into the frame1 towards the spindles1 which revolve with great rapidity1 producing by the motion of their flyers through the air a low musical hum1 which is supposed to have given the name of throstle to this machine4 ,the roving1 which may now be called yarn1 passing through an eyelet formed at the end of one of the arms of the flyer1 proceeds at once to other bobbins4 ,the yarn is wound upon the bobbins by a curious contrivance4 ,the bobbin fits very loosely upon the spindle1 and rests on its end upon a kind of platform4 ,the bobbin is not connected with the spindle1 except by the thread of yarn1 which has to be wound2 therefore1 as soon as the flyer is set spinning1 the thread drags the bobbin after it1 and makes it follow the motion of the spindle and fly2 but the weight of the bobbin1 and its friction on the platform1 which is promoted by covering the end with coarse cloth1 causes it to hang back1 and thus the double purpose is served1 of keeping the thread stretched and winding it on the bobbin much more slowly than the flyer revolves4 ,the yarn is equally distributed on the bobbin by a slow up-and-down movement of the platform4 ,illustration3 ,mule4 ,these effects are the same as were produced by the bobbin and fly-frame1 but in the throstle they are attained by simpler means4 ,in the former machine a distinct movement caused the bobbin to revolve quicker than the spindle4 ,in the throstle the bobbin is made to revolve by the pull of the yarn1 which is now sufficiently strong for the purpose2 but the roving in the bobbin-and-fly frame would not bear the strain4 ,the throstle is not often employed for very fine spinning1 because fine yarn would not bear the drag of the bobbin2 but in mule-spinning the yarn is wound at once upon the spindles without any strain4 ,in the mule the rolling is first drawn by the usual system of rollers1 and then stretched by a moveable carriage4 ,the effect of first drawing and then stretching is to make the yarn finer and more uniform1 as will be explained presently4 ,the spinning mule is the most interesting and impressive spectacle in a large cotton mill--on account of its vast extent1 the great quantity of work performed by it1 and the wonderful complication and ingenuity of its parts4 ,the spinning-mule consists of two principal portions3 the first1 which is fixed1 contains the bobbins of rovings and the drawing rollers2 the second is a sort of carriage1 moving upon an iron railroad1 and capable of being drawn out to a distance of about five feet from the fixed frame4 ,this carriage carries the spindles1 the number of which is half that of the bobbins of rovings4 ,motion is given to the spindles by means of vertical drums1 round which are passed slender cords1 communicating with the spindles4 ,there is one drum to every twenty-four spindles4 ,the carriage being run up to the point from which it starts in spinning1 the spindles are near to the roller-beam2 the rollers now begin to turn1 and to give out yarn1 which is immediately twisted by the revolution of the spindles2 the carriage then moves away from the roller-beam1 somewhat quicker than the threads are delivered1 so that they receive a certain amount of stretching1 which gives value to this machine4 ,the beneficial effect is produced in this way1--when the thread leaves the rollers1 it is thicker in some parts than in others1 and those thicker parts not being so much twisted as the thinner ones are softer1 and yield to the stretching power of the mule1 so that the twist is equalised throughout1 and the yarn becomes more uniform4 ,when the carriage has completed a stretch1 or is drawn out from about fifty-four to sixty-four inches from the roller-beam1 the drawing rollers cease to give out yarn1 but the spindles continue to whirl until the threads are properly twisted4 ,in spinning the finer yarns1 the carriage sometimes makes what is called a second stretch1 during which the spindles are made to revolve much more rapidly than before4 ,the drawing1 stretching1 and twisting1 of a length of thread being thus completed1 the mule disengages itself from the parts of the machinery by which it has hitherto been driven1 and the spinner then pushes the carriage with his knee back to the roller-beam1 turning at the same time with his right hand a fly wheel1 which gives motion to the spindles4 ,at the same time a copping wire1 as it is called1 is pressed upon the threads by the spinners' left hand1 and they are thus made to traverse the whole length of the spindle1 upon which they are then wound or built in a conical form1 which is called a cop4 ,these cops are used for placing in the shuttle in weaving1 and form the weft or short cross threads of the cloth4 ,illustration3 ,machinery for moving ,shuttle4 ,shuttle for ,power ,loom4 ,the yarn is now disposed of in various ways1 according to the use for which it is intended2 but it is often found convenient to make it up into hanks4 ,when the yarn is completed it is usually sent to the doubling and twisting mill1 for the purpose of being converted into what is now properly called thread4 ,although we are accustomed to apply the word thread to a thin narrow line of any fibrous material1 the manufacturer limits the term to that compound cord produced by doubling or twisting two or more single lines4 ,the single line he calls yarn1 two or more single lines1 laid parallel and twisted together1 he calls thread2 and of this there are many varieties1 such as bobbin-net-lace-thread1 stocking-thread1 sewing-thread1 c4 ,illustration3 ,gassing4 ,in fine spinning1 the yarn1 when doubled1 is for some purposes singed or gassed1 in order to get rid of the loose fibres1 and to make it more level and compact4 ,the process of singeing yarn strikes a stranger as being more remarkable than anything else in the mill4 ,in a long room in the upper part of the mill1 or in a shed attached to it1 are several tables1 lighted up with a large number of jets of flame1 about twelve inches apart1 producing a singular but pleasing effect4 ,above each flame is a little hood or chimney4 ,on entering this room the smell of burnt cotton is immediately perceived1 and on approaching the table1 one is surprised to see a fine delicate thread crossing each flame in two or three directions1 and apparently at rest2 but on following the course of this thread1 it is found to proceed from one bobbin1 which is rapidly spinning round1 and to pass through the flame to another bobbin1 which is also in rapid motion4 ,it is then seen that the thread is also moving at a rapid rate1 by which means alone does it escape being consumed4 ,the thread is led over pulleys1 so as to pass two or three times through the flame1 which singes off the loose fibres1 converting them into a reddish powder or dust1 which1 if blown about and inhaled1 would do great injury to the lungs2 this is why the gassing-room is in a remote or retired part of the building1 to prevent the air being disturbed by the bustle of the heavier parts4 ,illustration3 ,warping ,machines4 ,when cotton is intended to be woven into a fabric1 such as calico1 c4 the first operation consists in laying the requisite number of threads together to form the width of the cloth2 this is called warping4 ,supposing there to be #a1jjj threads in the width of a piece of cloth1 then the yarn1 wound on the bobbins as it leaves the hands of the spinner1 must be so unwound and laid out as to form #a1jjj lengths1 constituting1 when laid parallel1 the warp of the intended cloth4 ,the ancient method was to draw out the warp from the bobbins at full length on an open field 7and this is still practised in ,india and ,china71 but the warping-frame is now employed1 in which the threads are arranged1 by means of a frame turning on an upright centre4 ,when the warp is arranged round this machine1 the warper takes it off and winds it on a stick into a ball1 preparatory to the process of beaming or winding it on the beam of the loom4 ,the threads in this latter process are wound as evenly as possible on the beam2 a separator1 ravel1 or comb being used to lay them parallel1 and to spread them out to about the intended width of the cloth4 ,arrangements are then made for drawing or attaching the warp-threads individually to certain mechanism of the loom4 ,in this process all the threads are attached to stays fixed to two frames1 called treadles1 in such a manner that all the alternate threads 7#ast1 #c;d1 #eth17 can be drawn up or down by one heddle1 and all the rest 7#b;d1 #dth1 #fth1 c47 by the other4 ,there are three movements attending every thread of weft which the weaver throws across the warp4 ,in the first place he presses down one of the two treadles1 by which one of the two heddles is depressed1 thereby forming a kind of opening called the shed4 ,into this shed1 at the second movement1 he throws the shuttle1 containing the weft-thread1 with sufficient force to drive it across the whole web4 ,then at the third movement he grasps the batten1 which is a kind of frame1 carrying at its lower edge a comb-like piece1 having as many teeth as there are threads in the warp1 and with this he drives up the thread of weft close to those previously thrown4 ,one thread of weft is thus completed1 and the weaver proceeds to throw another in a similar way1 but in a reverse order1 that is1 by depressing the left treadle instead of the right1 and by throwing the shuttle from left to right1 instead of from right to left4 ,in the commonest mode of weaving the shuttle is thrown by both hands alternately2 but1 about a century ago1 ,john ,kay invented the fly-shuttle1 in which a string and handle are so placed that the weaver can work the shuttle both ways with one hand4 ,illustration3 ,weaving by hand4 ,in #afgh ,m4 de ,gennes invented a rude kind of weaving-machine1 intended to increase the power of the common loom2 and other looms were invented1 which were to be worked by a winch1 by water power1 or by some contrivance more expeditious than common hand-weaving2 but a greater step in advance was made by the invention of ,dr4 ,cartwright's power-loom in #aghe4 ,one cause which delayed the adoption of power-looms was the necessity for stopping the machine frequently1 in order to dress the warp with paste or size as it unrolled from the beam1 which operation required a person to be employed for each loom1 so that there was no saving of expense4 ,but the successive inventions of ,radcliffe1 ,horrocks1 ,marsland1 ,roberts1 and others1 have since brought the dressing-machine and the power-loom to a high state of efficiency4 ,illustration3 ,power ,loom4 ,taking a piece of calico as the representative of plain fabrics generally1 the mode of proceeding in power-loom factories may be shortly sketched as follows4 ,the warping-frame is so arranged as to be worked by steam-power1 and to bring the yarns into a parallel layer1 which is transferred to the dressing-machine4 ,this latter is a large piece of mechanism1 in which the threads dip into paste on their way to the warp-beam3 undergoing a process of brushing after the dipping4 ,after this dressing the drawing and mounting for the loom are attended to4 ,when the warp is properly arranged in the loom1 steam-power does all the rest2 it forms the shed or division of the warp into two parts1 it throws the shuttle1 it drives up the weft with the batten1 it unwinds the warp from the warp-roller1 and winds the woven material on the cloth-roller4 ,illustration3 ,spinning by hand4 ,,the ,,tailor4 ,illustration3 ,,workshop4 ,it would perhaps be too much to say that the more civilized a nation becomes1 the greater is the attention bestowed upon dress2 since it has happened that in countries not very far removed from barbarism1 vast importance has been given to external display1 and robes and trappings have been used to cover the savagery which had only just learned to delight in the pomp and magnificence of costly ornaments4 ,it is certain1 however1 that in all civilized nations dress is more than mere clothing1 and has a significance beyond the mere utility of protecting the body from cold or heat1 and adding to our physical comfort4 ,it is an old saying that some people may be clothed1 but that they are never dressed2 and the meaning of this is1 that dress is frequently an expression of character1 and will even make known the disposition of the wearer4 ,in the same way a change of fashion is often an indication of an alteration in the manners and way of living of a whole nation4 ,it is the business of the ,tailor1 then1 not only to make garments1 but to study the prevailing fashion1 and1 indeed1 to advise what alterations or slight differences in the cut and colour of clothes will be best suited to different people1 since on the way in which our clothes are made our personal appearance will very greatly depend1 and personal appearance is of no little importance1 since there are few people who are not strongly influenced by it4 ,the trade of the ,tailor is one of which very little can be said in the way of explanation1 since it mainly consists in cutting out cloth to the shapes necessary to be applied to each other in order to make the various garments2 and as this cannot be described without numerous diagrams1 and even with them could not easily be understood1 we must be satisfied to quote the instructions of a practical ,tailor on the subject of sewing4#c #c ,from the ,industrial ,library4 ,and1 first as to the different sorts of stitches1 which are3--the basting-stitch1 the back and fore-stitch1 the back-stitch1 the side-stitch1 and the fore-stitch2 also the back pricking-stitch1 the fore pricking-stitch1 the serging-stitch1 the cross-stitch1 and the button-hole-stitch2 besides which there is a distinct kind of stitch for hemming1 filling1 stotting1 rantering1 fine-drawing1 prick-drawing1 over-casting1 and also for making what are called covered buttons4 ,the basting-stitch is a long and slight stitch1 intended to be merely temporary1 or to fasten together some of the inner and concealed parts of the garment4 ,it is commonly used to keep the work in its proper position while being sewed4 ,illustration3 ,sleeve ,board4 ,the back and fore-stitch is made1 as the name implies1 by the union of back stitching and fore stitching2 in this stitch the needle is first put through the cloth1 and turned up in as short a space as is possible1 so as to make a neat and strong stitch when completed2 it is then put through the cloth again in the same place as at first1 and again turned up1 taking care that it passes through the cloth as nearly as possible within the same space as before4 ,this being done1 the first back-stitch is completed4 ,the second stitch is made by passing the needle forward upon the surface of the cloth1 but without taking hold of it1 over a space equal to the length of the first stitch2 the needle is again put through the cloth1 turned up1 and brought back to the place where it was last put through1 so as to form another back-stitch2 which is followed by another putting of the needle forward1 or1 in plainer terms1 another fore-stitch1 and so on in the same order1 until the seam is finished4 ,this kind of stitch is used for sewing linings1 pockets1 flannel garments1 and other thin fabrics4 ,there is no need to say much respecting the back-stitch1 as this may be understood from what is said above respecting the first stitch in back and fore-stitching4 ,this stitch is used for seams where strength is required2 it is also used for ornament instead of the side-stitch1 but in this case it must be very neatly and regularly made4 ,illustration3 ,goose4 ,flat ,iron4 ,french ,chalk4 ,thimble4 ,measure ,book4 ,rule4 ,the side-stitch is used for the edges of garments1 to keep them from rolling over1 or from being drawn out of shape4 ,it is always intended for ornament as well as use1 and requires a very quick eye and a careful hand to do it well4 ,in this stitch the needle is put through the cloth a little above or below the place from which it came out in the former stitch1 but it must be at a very little distance from this place1 or the sewing-silk will be visible on the surface of the cloth1 which is a great blemish1 and yet it must be far enough away from where it came out to prevent its breaking through1 in which case the stitch is lost both as to use and ornament4 ,care must also be taken that the stitches are at regular distances from each other1 and that the whole of them are placed at the same distance from the edge of the cloth4 ,in the fore-stitch1 as has been already hinted1 the needle1 when drawn out from the seam1 is always put forward1 so that an equal quantity of thread1 or a stitch of the same length1 is visible on each side of the cloth4 ,serge-stitching is done by passing the needle through the cloth from the under to the upper piece1 throwing the thread over the edges of the cloth1 so as to keep them closely together4 ,it is also used to join selvages together1 as also to prevent taking up more space for seams than can be spared1 when the pieces are barely large enough for the required purpose4 ,it is not1 however1 much used by tailors1 except when no great degree of strength is required4 ,the cross-stitch is formed by two parallel rows of stitches1 so placed as that the stitch in the upper row is opposite to the vacant space in the lower one1 the thread passing from one stitch to the other in diagonal lines4 ,it is used for keeping open the seams of such garments as require washing1 and also for securing the edges from ravelling out in such fabrics as are too loosely made to allow of their edges being fastened down by the filling-stitch4 ,in the button-hole-stitch the needle is first put through the cloth from the inner to the outer surface1 and before it is drawn out the twist is passed round the point of the needle1 and kept in that position till the needle be drawn out to the full length of the twist2 this forms a kind of loop1 called by ,tailors the 8purl10 at the top or edge of the opening1 and when regularly made is both ornamental and useful4 ,to increase the strength of this stitch1 and also to aid in making it true or exact1 a 8bar0 is formed on each side of the opening before the hole is begun to be worked4 ,this 8bar10 as it is called1 is made by passing the needle from one end of the opening to the other 7twice or three times71 so that there is a layer1 if it may be so called1 of twist stretching along its whole length 7and on each side7 upon which the whole is worked1 the workman taking care to keep the 8bar0 as near to the edge of the opening as possible1 without allowing it to come over1 in which case the button-hole would be neither strong nor neat4 ,illustration3 ,trousers ,pattern ,book4 ,the filling stitch is similar to that used in hemming2 the chief difference being in the direction given to the needle4 ,in hemming1 its point is directed outwards1 or from the workman1 but in filling it is directed inwards1 or towards him1 and in each should be a little1 but only a little1 slanted1 in order to give the sewing a neat appearance4 ,this stitch is used for sewing on facings1 and when made with neatness1 and without showing itself much on the outer side of the cloth1 is considered to be ornamental1 as well as useful4 ,illustration3 ,whisk4 ,measure4 ,hard ,brush4 ,reel4 ,iron ,holder4 ,stotting 7pronounced stoating7 is the stitch used for joining pieces of cloth so neatly that the join shall be but little visible1 and yet so strongly as to prevent the pieces from being easily parted4 ,in this kind of seam the pieces of cloth are not laid the one upon the other1 as in back-stitching1 but are placed side by side1 the edges being carefully fitted1 so as to prevent any irregularity or roughness in the work4 ,they are then sewn together by passing the needle half through the thickness of the cloth4 ,care must be taken to keep the stitches as near to each edge of the cloth as can be done without incurring the danger of its breaking through4 ,the needle is put in on the nearest edge of the two1 and must not be slanted in the direction given to it1 but put as straight forward as possible4 ,the stitch should be drawn close enough home to prevent the silk thread from showing itself on the right side of the cloth1 but yet not so close as to draw the edges into a ridge4 ,if the join be as neatly made as it may be1 it will1 when properly pressed1 be barely perceptible4 ,this stitch is used for joining the pieces of cloth of which facings1 collar-linings1 and other fillings-up of the inner sides of garments1 are made1 and also in other cases to prevent the taking up too much of the cloth by making a back-stitched seam4 ,illustration3 ,shears4 ,coat ,pattern ,book4 ,wax4 ,goose ,stand4 ,needle and ,thread4 ,rantering1 like stotting1 is intended to conceal a join in the cloth4 ,here1 however1 it is requisite to make a strong as well as a neat joining2 and therefore a seam is first sewn with a fore-stitch1 and then the rantering-stitch is worked upon or over this seam4 ,it should be worked with a very fine silk thread1 or with twist that has had one of the strands taken out4 ,the needle should be both long and slender1 and must be passed forwards and backwards over the seam1 so as to catch hold of its two sides1 and draw them closely together4 ,but in doing this care must be taken not to take a deep hold of the cloth3 the nap or wool is all that should be taken hold of1 and this must be done with a light hand1 while the stitches must be placed close to each other1 so that the seam may be well covered with wool2 when this is done1 the seam has to be 8rubbed up10 that is to say1 it must be held between the fore-finger and thumb of each hand1 these being placed upon the fore-stitching1 and its two edges brought as closely together as possible4 ,the rantering must then be slightly carded or scratched backwards and forwards with the point of a needle1 in order to bring the wool out again where it has been drawn in with the stitch2 the seam is then ready for pressing1 and1 if this operation be properly performed1 will be as much concealed as may be necessary2 while it will be much stronger than if it had been merely back-stitched4 ,in fine-drawing1 the stitch is formed in the same manner as in rantering1 but there is a difference in the way of placing the pieces that are to be joined1 i4e4 if they be separate pieces1 for this stitch is mostly used to close up places that have been accidentally cut1 or torn2 the two edges of the place requiring to be fine-drawn are first trimmed by cutting away the loose threads or ends of the cloth which may be upon them2 they are then placed and kept in as level or flat a position as is possible1 either with the fingers1 or by fastening them to a piece of stiff paper4 ,the needle should be both very small and long1 and the thread used1 whether it be of silk or twist1 should be very slender4 ,greater care is here necessary than in rantering1 to avoid taking a deep hold of the cloth2 the needle should be passed forwards and backwards1 over the opening1 and the thread should be drawn no closer or tighter than is quite needful in order to hide it in the wool4 ,the stitches must be placed as near to each other as is possible1 so as to prevent the edges of the cloth from being visible between them2 if it be needful to make a strong as well as a neat joining1 the fine-drawing should be repeated on the under side of the cloth1 but here it will not be needful to put the stitches so close together4 ,when the fine-drawing is done it must be pressed1 but with as light a hand and in as short a time as is practicable1 otherwise the sewing1 however neatly done1 will be visible1 and so far as it is so1 the design of the fine-drawing stitch will not be answered4 ,the stitch called prick-drawing is now but seldom used1 yet it may be proper to notice it briefly4 ,when this stitch is intended to be employed1 the edges of the cloth are first stotted together1 after which the needle is passed backwards and forwards in diagonal lines1 under the stotting1 so as to make the join more strong and durable than it can be made by merely stotting the pieces together4 ,this stitch is used where the cloth is very thick1 or hard and unyielding1 and1 consequently1 where the stotting-stitch would quickly give way without this support4 ,it is also better than a back-stitch seam for cloths of this description1 inasmuch as it can be made to lie more flat1 and thus to be more neat in its appearance1 than a common seam4 ,overcasting is used merely to secure the edges of thin and loose fabrics from 8ravelling out40 ,in using it1 the edges of the cloth1 whether it be woollen1 linen1 or cotton1 are first trimmed clear of the loose threads2 the needle is then passed through the cloth in a forward direction1 at about the distance of one-eighth part of an inch from the edge of the cloth1 and when drawn out it is carried 7from the left to the right1 and not1 as in other stitches1 from the right to the left7 about a quarter of an inch2 it is then again put through1 and on being drawn out it is made to pass over the thread leading from the preceding stitch1 so as to form a kind of loop on the edge2 which loop secures the edge from becoming too much frayed1 or ravelled4 ,all the tools that the apprentice or even the journeyman requires may be bought for a few shillings4 ,a yard of linen for a lap-cloth2 two pairs of scissors1 one pair moderately large1 for common use1 and the other small1 for button-holes2 a thimble2 a small piece of bees-wax2 and threepennyworth of needles1 are all that he will have occasion to buy so long as he is not a master1 or a journeyman working at home1 when he must procure a sleeve-board and an iron4 ,the more expensive part of even these few implements1 viz4 the scissors1 will1 with tolerable care1 last for a number of years with only the trifling expense of being occasionally sharpened by the cutler4 ,all the implements used by the ,tailor are so well known as to need no particular description2 the sleeve-board is used to place in the sleeve of a coat while the seams are pressed with the heated iron or the goose4 ,in the measure book the dimensions are written when measurement of a customer is made1 and the ,french chalk marks the direction in which the cloth is cut to the pattern of the various shapes1 which are afterwards sewn together to make complete garments4 ,,the ,,tanner4 ,illustration3 ,,the ,,pits4 ,leather is a substance universally used amongst civilized and very generally amongst barbarous nations2 it is made from the skins of animals1 which are tanned1 or prepared with some substance1 having the power of converting the perishable skin1 that decays readily when wet or moist1 into a lasting and comparatively imperishable leather4 ,the preparation of skins by tanning or other similar processes has been practised from the earliest times2 and although it has engaged the attention of several scientific men1 and has been the subject of many curious experiments1 it has received less alteration from recent improvements in chemical science than many other manufacturing processes4 ,several plans1 which have been suggested with a view to expediting the process1 which on the old system is a very tedious one1 have been found to injure the quality of the leather1 and have therefore been wholly or partially abandoned2 and others1 which appear to be more successful1 are as yet adopted by a few manufacturers only4 ,the larger and heavier skins operated upon by the ,tanner1 as those of bulls1 buffaloes1 oxen1 and cows1 are technically distinguished as hides1 while the name skins is applied to those of smaller animals1 as calves1 sheep1 and goats4 ,the process necessary to convert hides into the thick hard leather used for the soles of boots and shoes1 and for similar purposes will first be noticed4 ,the hides are brought to the ,tanner either in a fresh state1 when from animals recently slaughtered1 or1 when imported from other countries1 dried or salted1 and sometimes both1 for the sake of preserving them from decomposition4 ,in the former case the horns are removed1 and the hide is scraped to cleanse it from any small portions of flesh or fatty matter that may adhere to the inner skin2 but in the latter it is necessary to soften the hides1 and bring them as nearly as possible to the fresh state1 by steeping them in water1 and repeated rubbing or beating4 ,after this the hair is removed1 sometimes by steeping the hides for several days in a solution of lime and water1 which has the effect of loosening the hair and epidermis1 or outer skin2 and sometimes by suspending them in a close chamber called a smoke-house1 heated a little above the ordinary temperature of the atmosphere by means of a smouldering fire1 in which case the epidermis is loosened by a very slight putrefaction4 ,in either case1 when the hair and epidermis1 or cuticle1 are sufficiently loosened1 they are removed by scraping with a curved knife1 the hide being laid upon a convex bench or beam4 ,illustration3 ,unhairing the ,hides4 ,striking the ,hides4 ,the hides are prepared for the actual tanning1 or immersion in a solution of bark1 by steeping them for a few days in a pit containing a sour solution of rye or barley flour1 or in a very weak menstruum1 consisting of one part of sulphuric acid mixed with from five hundred to a thousand parts of water4 ,by this process1 which is called 8raising10 the pores of the hides are distended and rendered more susceptible of the action of the tan4 ,oak-bark is the substance most commonly used to supply the astringent principle1 and it is crushed or ground to powder in a bark-mill4 ,in the old method of tanning1 which is not yet entirely abandoned1 the hides and powdered bark were laid in alternate layers in the tan pit1 which was then filled with water to the brim4 ,after some months the pit was emptied1 and refilled with fresh bark and water2 and this process was repeated whenever the strength of the bark was exhausted4 ,in this way1 the time required for impregnating the hides varied1 according to their thickness and other circumstances1 from one to four years4 ,the process has been greatly expedited by the improvement1 introduced in consequence of the experiments of ,m4 ,seguin1 a ,french chemist1 of tanning with concentrated solutions of bark1 formed by passing water through a mass of powdered bark1 until1 by successive filtrations1 it is completely deprived of its soluble tanning principle4 ,illustration3 ,bark ,box4 ,barrow4 ,the variations of practice among different ,tanners extend to the substance used as an astringent1 as well as to the manner of applying it4 ,ground oak-bark1 which was formerly the only material in common use1 and is still the most general1 produces good leather of a light fawn colour4 ,valonia1 of which considerable quantities are imported for the use of ,tanners1 produces leather of great solidity and weight1 the colour of which is inclined to grey1 and which is more impervious to water than that made with oak-bark4 ,valonia consists of the acorns of the ,quercus gilops1 and is brought from the ,levant and the ,morea4 ,catechu1 or terra japonica1 the extract of the ,acacia ,catechu1 produces leather of a dark reddish fawn colour1 which is light1 spongy1 and very pervious to water4 ,illustration3 ,fleshing ,knife1 and ,section4 ,shaving ,knife1 and ,section4 ,striking ,pin1 and ,section4 ,unhairing ,knife1 and ,section4 ,when the process is complete1 the hides are hung up in a shed and allowed to dry slowly2 and while they are drying they are compressed by beating1 or rubbing1 or by passing them between rollers1 to give them firmness and density4 ,a yellow deposit is now found upon the surface of the leather1 to which the name of 8bloom0 or 8pitching0 is technically given4 ,we have hitherto alluded chiefly to the preparation of the thick hides used for sole leather1 among which several varieties may be found1 each distinguished by a different technical name1 by which its thickness1 quality1 or mode of preparation is known2 but the thinnest and weakest hides1 as well as the skins of calves and other animals1 are also prepared for use as upper leathers1 in which case it is necessary to reduce their thickness by shaving or paring them down upon the flesh or inner side1 before they are subjected to the action of the tanning infusions4 ,such hides or skins also require1 after leaving the hands of the ,tanner1 to be rubbed1 softened1 and dressed by the currier1 in order to bring them to the necessary degree of flexibility and smoothness4 ,the currier also has recourse to shaving or paring with a peculiarly formed knife1 to bring the skin to the requisite tenuity2 and it is his office to blacken the surface1 which1 for common shoe leather1 is done on the flesh side1 although for some purposes leather is blackened on the outer or grain side4 ,horse-hides1 which are comparatively weak and thin1 are sometimes dressed in the latter way1 under the name of ,cordovan hides1 from the circumstance of such leather having been formerly made at ,cordova1 in ,spain4 ,calf-skins supply the quality of leather most generally preferred for the upper part of boots and shoes4 ,of the thin skins prepared for ornamental purposes1 many are tanned with a substance called sumach1 prepared from a plant of the same name4 ,the tanning is performed by sewing up each skin into the form of a bag1 with the grain or hair side outwards1 and nearly filling it with a strong solution of sumach in water4 ,the bag is then fully distended by blowing into it1 and the aperture is tied up2 after which it is thrown into a large shallow vessel filled with hot water containing a little sumach4 ,the distended bags float in this vessel1 and are occasionally moved about with a wooden instrument until the solution which they contain has thoroughly penetrated their substance4 ,owing to the thinness of the skins and the heat to which they are exposed1 this operation is performed in a few hours4 ,the process is expedited by taking the bags out of the solution1 and piling them upon a perforated bench or rack at the side of the tub1 so that their own weight may force the confined liquid through the pores4 ,illustration3 ,apron4 ,gloves4 ,whetter4 ,roller4 ,leoline4 ,when the tanning is completed1 the bags are opened to remove the sediment of the sumach2 the skins are washed1 rubbed on a board1 and dried2 after which they are ready for dyeing and finishing with a ridged instrument1 which imparts to the surface that peculiar grain by which morocco leather is distinguished4 ,an inferior kind of leather1 known as 8imitation morocco10 is prepared in a similar manner from sheepskins4 ,illustration3 ,plungers4 ,tongs4 ,jet4 ,hook4 8,tawing0 is the name applied to the process by which the skins of lambs and kids are converted into soft leather by the action of alum4 ,of this kind of leather gloves are usually made4 ,the jet and plungers used for immersing the hides in the tan1 the tongs and hook for removing them1 and the other implements1 are easily understood as applied to the various processes here mentioned4 ,illustration ,,the ,,shoemaker4 ,illustration3 ,,workshop4 ,the trade of the ,shoemaker naturally follows that of the tanner1 since leather is the material principally employed in making coverings for the feet2 the tough hides of animals being used for the same purpose in countries where the art of tanning is either unknown or not practised4 ,scarcely any handicraft employment engages the attention of so many persons in this country as boot and shoe making4 ,from the fashionable bootmaker to the poor cobbler1 who crouches in a stall under a house in some narrow street1 is a wide interval1 and this interval is filled up by numerous grades4 ,at ,northampton boots and shoes are made on a very large scale for the ,london markets2 they include chiefly the cheap varieties1 but at some of the recent exhibitions of manufactures the ,northampton bootmakers have exhibited specimens of workmanship which are considered to be quite equal to those of ,london or ,paris4 ,at ,edenbridge1 in ,kent1 and at other places1 the strong coarse 8hob-nailed0 shoes are made1 which are so much worn by waggoners and others4 ,the ,london makers import from ,paris very large quantities of boot fronts1 which1 when combined with other parts of ,english manufacture1 constitute many of the 8,french boots0 which now glisten in the windows4 ,notwithstanding the large number of persons employed in these avocations in ,england1 and the abundant supply of leather1 there is still a considerable import of boots and shoes from abroad1 chiefly ,france4 ,in the old statutes a ,shoemaker is called a cordwainer1 apparently a corruption of the ,french cordonnier1 which means a worker of ,cordova leather4 ,the companies of ,shoemakers in our ancient towns were incorporated under this name2 and where some of these companies now exist1 they are known by the same name4 ,as a legal term1 cordwainer is still used4 ,the trade1 as now followed in ,london and other principal places1 is subdivided into about twenty branches4 ,the following may be set down as the chief3 the shoeman1 or maker of the sole part of the shoe2 the bootman1 or maker of the sole part of the boot2 and the boot closer1 or joiner together of the leg1 vamp1 c4 ,the labour of these is especially directed to what is called the men's line2 whilst others make the ladies' shoes or boots4 ,there are many women1 too1 who get a livelihood by closing the shoe1 while others again follow the various sorts of binding4 ,the mechanical processes1 after marking and cutting out the leather1 consist chiefly in various kinds of strong needlework1 such as the lasting or tacking of the upper leather to the in-sole1 the sewing in of the welt1 the stitching to this welt of the out or top sole1 the building and sewing down of the heel1 and the sewing or closing of boot legs4 ,the boot closer is the most skilful of the persons employed1 and receives the highest wages4 ,the materials with which the ,shoemaker works are generally called the grindery1--they are so called at least through ,england and ,scotland1 though in ,dublin it is called finding4 8,the cause of this technicality10 says ,mr4 ,james ,devlin1 in his most interesting description of the trade of the ,shoemaker in the ,industrial ,library1 8is now1 ,i believe1 scarcely known to any one in the trade4 ,the relation to whom ,i was apprenticed1 a man of a very active and inquisitive turn of mind1 told me its history1 which it may be worth while here to relate4 8,formerly1 before hemp1 flax1 wax1 hairs1 or any description of tools1 were sold1 as now1 in shops set apart to this particular business1 the shoemaker1 not using the peculiar sort of stone rubber or the emery composition which he now uses to sharpen his knives upon1 was in the habit occasionally of taking his knives to be ground 7as the ,french shoemaker does at the present day7 to some of the common knife-grinders of the neighbourhood4 ,the knife-grinder having thus the ,shoemaker for a regular customer1 began in time to add to his usual business that of selling hemp1 c42 hence his little shop being termed the grindery1 every thing he sold became known under this name1 and is still continued40 ,the tools of the ,shoemaker are in their collective form denominated his kit4 ,anciently1 and in the old songs of the trade1 they were called 8,st4 ,hugh's bones10 from a now almost forgotten1 though somewhat pleasant tradition4 ,in ,stow1 and in ,randle ,holme's 8,academie of ,armorie10 #afhh1 we find this term2 as1 also1 in the still older romance of 8,crispin and ,crispianus20 and in two plays1 8,the ,shoemaker is a ,gentleman10 and the 8,shoemaker's ,holiday10 of the beginning of the seventeenth century4 ,the kit of the ,shoemaker is1 however1 no longer now1 as formerly1 made up of 8bones0--saint or infidel1 human or brute1--but principally of good and kindly steel2 purchased ready-made at the grinder's1 or the grindery establishments before spoken of1 and kept afterwards 7in this country1 at least1 and in ,america7 in repair and proper order by the ingenuity and care of the workman himself2 though in ,france1 and generally on the continent1 much of this is done by another person1 to whom such occupation is the sole means of livelihood4 ,under the general term kit is comprehended the pincers1 nippers1 hammer1 the various descriptions of awls1 of setting irons1 and many other articles4 ,it has often been a matter for great surprise that the ,shoemaker should sit in such a cramped and unhealthy position at his work1 crouched over his clamps as he holds the leather in them between his knees while engaged in sewing1 or over the block1 which he holds fast to his thigh with the stirrup that passes underneath his foot4 ,illustration3 ,nippers4 ,awl4 ,stirrup4 ,lapstone4 ,hammer4 ,clamps4 ,many inventions and improvements have been made for enabling the ,shoemaker to stand during a great part of his time1 and some of these seem well adapted to supersede the old position1 but at present they have been only partially adopted4 ,the ,shoemaker's thread being tipped with bristles1 no needle is required for sewing2 but the thread itself is passed through the hole made with the awl4 ,quickly goes in the awl1 and as quickly is out again1 but not before the hair from the fingers of the left hand has found the passage1 without being at all directed by the sight1 but literally in the dark2 and hence the term blind stabbing1 the right hand hair immediately following in the opposite course1 the closed thumb and fore-finger of either hand nipping at the moment the hairs from these different directions1 and drawing the same as instantly out1 at once completing the stitch4 ,a proficient closer1 or closer's boy--for here1 in general1 the boy is even more expert than the man--will in the space of half an hour stab the four side rows and the two back rows of the counter of a boot1 each inch of stitching taking about twenty stitches1 and the entire work averaging about fifteen inches1 three hundred stitches being thus put in in thirty minutes1 or fifty every five minutes1 each stitch requiring in itself six distinct operations--the skill of sight or distance1 the putting in of the awl1 and again its withdrawal1 the putting in the left-hand hair1 and again of the right1 and lastly1 the careful though rapid drawing1 or rather twitching1 out of the thread itself4 ,the closer needs little kit3 a slip of board to fit or prepare the work upon2 a pair of clamps2 a block2 a knife2 about three awls1 two differently-sized closing awls1 and one stabbing awl2 two seam-sets1 or it may be three--one for the stabbed sides2 a stirrup2 a case of needles 7short blunts71 and a thimble4 ,illustration3 ,fore-part ,iron4 ,seat ,iron4 ,seat ,file4 ,gigger ,iron4 ,jim ,crow4 ,breaker4 ,glazing ,iron4 ,bevel ,iron4 ,the lining in all shoes1 at least1 but those of the very strongest kind1 is entirely the work of the woman1 being done with the needle1 and elegantly it often is done4 ,after the lining1 the upper has to be set2 a matter soon effected2 the flat-seam-set1 or1 if stabbed1 the stabbing-side-set1 being heated at a candle 7though this is not necessary1 and might from the danger of the practice be well dispensed with7 and a little dissolved gum being rubbed on the seam1 the set is immediately to be somewhat forcibly and briskly pressed along the line of stitching1 which thus takes an almost instant polish1 and being also hardened1 the upper becomes ready for shop2 that is1 to be sent to the maker1 or shoeman1 to finish by putting in the welt1 soles1 and other parts of the shoe2 the 8stitching0 being effected with a square awl4 ,illustration3 ,knife4 ,last4 ,paste ,horn4 ,the number of tools used by the ,boot and ,shoemaker who combines all the branches of the trade is very great1 although few of them are remarkably expensive1 except some of the patent metal or hardwood lasts1 on which the shoes or boots are placed4 ,the lapstone on which the leather is hammered after being damped2 and the various kinds of irons used for rubbing1 paring1 or shaping the soles and other parts of the shoe1 are the principal implements1 beside the awls1 knives1 hammers1 and rasp4 ,the glazing iron is used for burnishing the heel of the boot or shoe2 the paste horn for containing the paste used in the inside lining of the shoe or boot2 the irons for setting up the leather beside the stitching1 and the ,jim-crow1 which is a small toothed wheel running in a handle for the same purpose4 ,the long stick is used for 8sleeking10 or smoothing and softening the upper part of the boot or shoe1 after it has been made and placed on the block1 in order to take out any wrinkles that may remain4 ,illustration3 ,long ,stick4 ,rasp4 ,it would be impossible to give any clear description of all the operations of the trade of the ,shoemaker in the space devoted here to this particular business1 and even were it attempted1 no very clear idea could be conveyed of the various portions of his work2 since1 like the tailor1 he has first to cut out the leather to the proper shape for making the various parts1 which have afterwards to be put together4 ,indeed1 beyond mentioning the uses of the various tools1 most of which are simple enough1 little can be said to explain the operation of the ,shoemaker that would not require actual inspection of the different processes2 although many of them may be understood by looking at a shoe1 after having observed the accompanying pictures and having read what has been said about the tools employed4 ,,the ,,saddler ,,and ,,harness ,,maker4 ,illustration3 ,,workshop4 ,the manufacture of saddles and harness for horses is one requiring very considerable skill and no little patience1 since on the ability of the ,saddler depends not only the health and comfort of the horse1 but the safety of the rider4 ,the beauty and finish of the harness and its appurtenances are so essential to the proper appearance presented by the whole equipage1 that a very great deal of attention is now given even to the smallest details1 such as buckles1 mounts and ornamental sewing on straps and traces4 ,illustration3 ,spokeshave4 ,cutting ,gauge4 ,dead ,punch4 ,compasses4 ,mallet4 ,hand ,iron4 ,the operations in the trade of the ,saddler are so similar to those of the shoemaker1 as far as the stitching and cutting of leather are concerned1 that they require very little description4 ,the most difficult part of his business is the skilful making of saddles4 ,to fit the pigskin over the iron shape1 and skilfully to arrange the padding1 is often a very troublesome task1 where a horse requires some peculiarity of make before he can be well fitted2 and to ensure a perfect smoothness and finish a skilful use of the hand iron and the spokeshave is necessary4 ,similar care has to be taken in forming the collars to which the harness is attached2 and indeed no part of the ,saddler's work can be carelessly performed without serious risk either to the horse or its owner4 ,illustration3 ,needle and ,thread4 ,clamps4 ,lead ,piece4 ,hand ,knife4 ,punch4 ,round ,knife4 ,pricking ,iron4 ,hand ,knife4 ,hammer4 ,as a great part of the ,saddlers' work consists of sewing1 he uses the clamps to hold the leather between his knees1 in the same way as they are used by the shoemaker2 but although he employs the sewing awl for drilling holes1 or1 at all events1 the pricking iron1 the sewing is done with needles and strongly waxed thread4 ,the various kinds of knives are used for cutting and paring the leather2 the cutting gauge and compasses for regulating the cutting1 the hammer for driving the small nails used in the work1 and the mallet for striking the pricking iron or punches4 ,the punch is used for making the holes in the straps to receive the tongue of the buckle1 and is therefore a hollow tube with a sharp cutting edge1 so that it will cut out a little round piece of the leather4 ,the dead punch is made solid1 and is not intended for cutting4 ,the leather1 when it has to be cut with the punch1 is placed on the lead piece1 a small square block of lead1 which being soft allows a slight yielding of the leather1 and at the same time does not blunt the edge of the punch when it has passed through the hole4 ,illustration3 ,edging ,iron4 ,seat ,awl4 ,packing ,awl4 ,sewing ,awl4 ,double ,crease4 ,single ,crease4 ,nail ,claw4 ,the seat awl and packing awl are used in the padding and making of saddles and collars2 the nail claw for removing nails by which the leather has been fastened down4 ,the various kinds of creases are for the purpose of making channels in the leather along the edges which have to be sewn1 so that the stitches are sunk below the surface1 and the thread will not so easily wear out4 ,the edging iron is for a similar purpose4 ,in common saddlery some of the comparatively unimportant straps1 or the smaller gear1 are not sewn at the edges1 and indeed do not require it1 although a great deal of the ,saddler's sewing is for ornamental purposes4 ,in order to make the whole look uniform1 however1 these straps are not left plain1 but are creased at the edges1 and the channels thus made are marked with the pricking iron1 to give them the appearance of having been stitched4 ,the ,saddler is better off than the shoemaker1 inasmuch as he generally sits to work at a bench1 and need not occupy such a constrained and unhealthy position4 ,some account has already been given of the preparation of leather1 but it will be desirable here to mention other sorts1 some of which particularly belong to the business of harness making4 ,illustration3 ,screw ,crease4 ,varnish ,pot4 ,sponge4 ,sheep-skins1 when simply tanned1 are employed for inferior bookbinding1 for leathering bellows1 and for various other purposes for which a cheap leather is required4 ,all the whit-leather1 as it is termed1 which is used for whip-lashes1 bags1 aprons1 c4 is of sheep-skin2 as are also the cheaper kinds of wash-leather1 of which gloves1 under-waistcoats1 and other articles of dress1 are made4 ,mock1 or imitation morocco1 and most of the other coloured and dyed leathers used for women's and children's shoes1 carriage-linings1 and the covering of stools1 chairs1 sofas1 writing-tables1 c4 are also made of sheep-skin4 ,lamb-skins are mostly dressed white or coloured for gloves2 and those of goats and kids supply the best qualities of light leather1 the former being the material of the best morocco1 while kid leather affords the finest material for gloves and ladies' shoes4 ,leather from goat-skins1 ornamented and sometimes gilt1 was formerly used as a hanging or covering for walls4 ,illustration3 ,harness4 ,deer and antelope skins1 dressed in oil1 are used chiefly for riding breeches4 ,horse-hides1 which1 considering their size1 are thin1 are tanned and curried1 and are used by the ,harness ,maker1 especially for collars1 and occasionally1 when pared thin1 for the upper leathers of ladies' walking shoes4 ,dog-skins are thick and rough1 and make excellent leather4 ,seal-skins produce a leather similar but inferior to that supplied by dog-skins2 and hog-skins afford a thin but dense leather1 which is used mostly for covering the seats of saddles4 ,currying is the general name given to the various operations of dressing leather after the tanning is completed1 by which the requisite smoothness1 lustre1 colour1 and suppleness1 are imparted4 ,the processes of the ,currier are various4 ,the first is styled 8dipping0 the leather4 ,it consists in moistening with water1 and beating upon a trellis-work of wooden spars with a mallet or mace4 ,after this beating1 by which the stiffness of the hide or skin is destroyed1 it is laid over an inclined board1 and scraped and cleaned1 and1 wherever it is too thick1 pared or shaved down on the flesh side by the careful application of various two-handled knives1 and then thrown again into water1 and well scoured by rubbing the grain or hair side with pumice-stone1 or with a piece of slatey grit1 by which means the bloom1 a whitish matter which is found upon the surface in tanning1 is removed4 ,illustration3 ,rule4 ,pincers4 ,file4 ,pliers4 ,the leather is then rubbed with the pommel1 a rectangular piece of hard wood1 about twelve inches long by five broad1 grooved on the under surface1 and fastened to the hand4 ,the ,currier uses several of these instruments1 with grooves of various degrees of fineness1 and also1 for some purposes1 pommels of cork1 which are not grooved at all4 ,the object of this rubbing is to give grain and pliancy to the leather4 ,the leather is then scraped with tools applied nearly perpendicular to its surface1 and worked forcibly with both hands1 to reduce such parts as may yet be left too thick1 to a uniform substance4 ,after this it is dressed with the round knife1 a singular instrument which pares off the coarser fleshy parts of the skin4 ,in addition to these operations1 the ,currier uses occasionally polishers of smooth wood or glass1 for rubbing the surface of the leather2 and when the leather is intended for the use of the shoemaker1 he applies to it some kind of greasy composition called dubbing or stuffing4 ,leather is occasionally dressed 8black on the grain10 or having the grain side instead of the flesh coloured4 ,the currying operations in such a case are similar to those above described1 but the finishing processes are rather different4 ,the leather is rubbed with a grit-stone1 to remove any wrinkles and smooth down the coarse grain4 ,the grain is finally raised by repeatedly rubbing over the surface1 in different directions1 with the pommel or graining board4 ,japanned leather of various kinds is used in coach making1 harness making1 and for various other purposes4 ,patent leather is covered with a coat of elastic japan1 which gives a surface like polished glass1 impermeable to water2 and hides prepared in a more perfectly elastic mode of japanning1 which will permit folding without cracking the surface1 are called enamelled leather4 ,such leather has the japan annealed1 something in the same mode as glass2 the hides are laid between blankets1 and subjected to the heat of an oven at a peculiar temperature during several hours4 ,,the ,,hatter4 ,illustration3 ,,cutting ,,machine4 ,the trade of the ,hatter is confined to a few countries of ,europe2 but1 as the fashion of hats is at present mostly restricted1 both here and in most parts of the ,continent1 to those black stiff cylindrical coverings of silk which custom has ordained we shall wear1 greatly to our own discomfort1 and at a great expense1 the business is of considerable importance1 and the making of hats has grown into a large branch of industry4 ,before the introduction of that kind of silk which bears a long pile1 like velvet1 and is known as plush1 beaver was the material principally used for hat making2 but beaver hats are much more expensive1 though they are now seldom made of the skin or fur of the beaver1 which has grown remarkably scarce1 in consequence of the land which the animals formerly occupied having become inhabited4 ,illustration3 ,cutting out4 ,bowing4 ,beaver hats of the finest quality are made with lamb's wool and the fur of ,english rabbits4 ,to form the body of the hat1 the wool and rabbit's fur are separately bowed by bringing a set of strings attached to a bow in contact with a heap of the material1 and then striking the strings1 so as to cause violent vibrations1 and thus separate the filaments4 ,the two substances are next bowed together until they are intimately mixed2 after which the mass is spread evenly1 covered with an oil-cloth1 and pressed to the state of an imperfectly tangled felt4 ,the next process is to cover the felt with a triangular piece of damp brown paper1 and then to fold it in a damp cloth1 and work it well with the hand1 pressing and bending1 rolling and unrolling it1 until the interlacing or felting is much more perfect1 and the mass is compact4 ,the felt thus prepared is next taken to the wide brim of a boiler charged with hot water and beer grounds1 and a small quantity of sulphuric acid2 it is well rubbed and rolled until it no longer contracts4 ,the felt is next stiffened with shellac1 a solution of which is applied by means of a brush to both sides of the felt2 after which it is heated in a stove1 and by this means the whole substance becomes duly impregnated with the resin2 this renders the hat nearly waterproof4 ,illustration3 ,bow for ,beaver4 ,to form the nap of a hat1 one half or three-fourths of an ounce of beaver1 and some other less costly fur1 are bowed together and imperfectly felted in the manner already described1 and shaped the same as the body to which it is to be applied2 that body is then softened by immersing it in the boiler1 when the nap is applied and worked as in felting1 until the required union is effected between the two bodies4 ,the felt thus covered is brought to the proper shape by working it on a wooden block1 and is then dyed black4 ,the hat is softened by steam1 the crown is strengthened by placing in it a disc of scaleboard1 and linen is pasted over this4 ,the nap is raised and a uniform direction given to its fibres by means of warm irons and hair brushes4 ,the last processes are lining and binding1 when the hat is ready to be worn4 ,in the low-priced hats of the present day1 commoner wool and fur1 and smaller quantities of each1 are used4 ,illustration3 ,lathe4 ,finishing4 ,silk hats consist of a cover or exterior part made of silk plush1 which is laid upon a foundation of chip1 stiffened linen1 or some other light material1 previously blocked into shape4 ,the so-called velvet and satin hats deserve those titles only so far as the plush resemble those materials4 ,the plush is mostly woven in the north of ,england4 ,paris hats are for the most part made in ,england1 the silk plush being imported from ,france4 ,illustration3 ,rounding ,card1 ,no4 #a4 ,rounding ,card1 ,no4 #b4 ,finishing ,iron4 ,brow-piece4 ,blistering ,iron4 ,card4 ,polishing ,block4 ,multer4 ,brush4 ,the various tools employed are mostly used for shaping the different parts of the hat4 ,the cutting machine1 for dividing and preparing the felt and other materials2 the block1 on which the body of the hat is formed previous to its being placed in the lathe1 where it is made perfectly round2 the brow-piece1 for shaping the hat where it fits the head2 the card1 a sort of wire brush for scratching up or carding the fibre of the silk or beaver after the hat is made2 the rounding cards1 for pressing and completing the hat near the brim2 the curler1 for turning up and shaping the brim2 the multer1 finishing iron1 and blistering iron1 are used for shaping and smoothing2 the polishing block holds the hat while it receives the final process of brushing and smoothing with a pad of velvet called the veleure4 ,illustration3 ,curler4 ,block4 ,veleure4 ,,the ,,miller4 ,illustration3 ,,water-,,mill4 ,there is scarcely a boy to be found who1 when he has been into the country and seen the wheel of the old water mill going round1 or the fans of the windmill slowly revolving in the air1 has not thought that it would be pleasant to follow the business of a ,miller4 ,millers are proverbially jolly fellows1 and their houses and the mills themselves are generally very picturesque1 and stand in pleasant country places2 then1 again1 what wonderful fat perch and chub and pike can be caught in the weir or the mill stream1 and what a quiet sleepy occupation it must be to lie on the grass or in some great room in the mill1 watching the fans1 or listening to the summer breeze wafting through the sails6 ,if anybody should think1 however1 that the ,miller's life is a lazy one he had better alter his opinion2 for1 unless he wishes to starve amidst plenty1 the ,miller must be up betimes1 and1 besides working himself1 keeping a good look-out amongst his men1 lest both he and his customers should suffer by their negligence4 ,the mortar would seem to be the earliest machine used for the purpose of bruising or reducing grain to a powder1 or into a state fit for the making of bread4 ,by means of the handle the pestle would with tolerable facility be driven round the mortar1 and the grain reduced to a powder1 as is done with certain drugs by the pestle of the apothecary of the present day4 ,in process of time1 shafts were added to these machines2 and in the opinion of ,beckmann1 the oldest cattle mills resembled those described in ,sonnerat's ,voyage to the ,east ,indies1 in which the pestle of a mortar1 fastened to a stake driven into the earth1 is affixed to a shaft1 to which two oxen are yoked4 ,these oxen are driven by a man1 while another is employed in dropping the grain into the mortar and placing it under the pestle4 ,we have good reason for knowing that the ,romans1 for a long time1 used no other instrument than the pestle and mortar4 ,pounding continued in use among the ,romans so late as after the era of ,vespasian4 ,this fact clearly proves that the ,romans were many ages behind the ,eastern world in the arts of civilization1 for grinding of corn into flour was practised1 we know1 in the times of the patriarchs1 and was probably the invention of the antediluvian world4 ,the subject-,britons universally adopted the ,roman name1 but applied it1 as we their successors apply it at present1 only to the ,roman mill2 still distinguishing their own original mill as we distinguish it1 by its own original denomination of a quern4 ,a ,roman or water mill was probably erected at every stationary town in the kingdom1 and it is quite certain that one was erected at ,mancunium 7,manchester71 serving equally the purposes of the town and the uses of the garrison4 ,one alone would be sufficient1 as the use of hand-mills was at that time very common in both1 many such having been found about the site of the station particularly1 and the use of them generally having being retained among us very nearly to the present period4 ,such mills it would be particularly necessary to have in the station1 that the garrison might be prudently provided against a siege4 ,the ancient ,asiatic hand-mill consists of two flat round stones1 about twenty inches or two feet in diameter1 kept rolling one on the other by means of a stick1 which does the office of a handle4 ,the corn falls down on the undermost stone1 through a hole in the middle of the uppermost1 which by its circular motion spreads it on the undermost1 where it is bruised and reduced to flour2 this flour1 working out at the rim of the millstones1 lights on a board set on purpose to receive it4 ,the bread made of it is said to be better tasted than that made by either wind or water mills3 these hand-mills cost only a few shillings of ,english money4 ,this description of mill is frequently alluded to in the ,scriptures1 and it was the practice for the women to grind corn every morning by means of hand-mills2 and in the ,east1 or at least in many parts of it1 it continues to be the practice to this day4 ,water wheels1 as far as the figure and construction are concerned1 may be reduced to three kinds1 and they are usually known by the names--overshot wheel1 balance wheel1 breast wheel1 and undershot wheel4 ,illustration3 ,mill4 ,in an overshot wheel1 the water is conducted over the top of the wheel1 and acts first by its momentum or mere movement1 or motion1 and then by its weight--the weight being its principal power in impelling the wheel round1 the mere movement or motion of the water producing in this case little effect4 ,the water is received into buckets placed all around the circle of the wheel4 ,it first strikes the wheel at the top1 and filling the first bucket1 by its momentum or moving power1 and more particularly by its weight1 it sets the wheel in motion1 and consequently makes that side heavier2 and as fresh buckets rise to receive the water1 while those below have emptied themselves1 a constant tendency to motion is created1 and rotation is produced4 ,in a balance wheel1 the water strikes the wheel not at the top1 but always more or less above its centre1 or axle4 ,this wheel differs in no respect from the overshot wheel in its construction4 ,it is employed where there is not a sufficient fall for an overshot wheel1 which requires less water in consequence of its commanding a much greater leverage4 ,in an undershot wheel the water acts only by its momentum1 or moving power4 ,the circumference of the wheel1 instead of being supplied with buckets1 as in the overshot1 and breast or balance wheels1 is furnished with floats1 or float boards1 as they are called1 and1 being exposed to the action of a running stream1 generally1 if not always1 increased in rapidity by making an artificial fall1 is thus driven round1 and in flour-mills its force is communicated by cog-wheels to the stones employed in reducing corn to meal4 ,in a breast wheel1 the water has no previous fall1 and therefore does not strike the floats at the bottom of the wheels1 as in the undershot wheel1 with an increased velocity4 ,the breast wheel is therefore fixed in what is called a race1 formed of stone or brick work1 agreeing with the curvature of the wheel1 and being thus let on from its own level1 acts both by its weight and momentum1 or movement4 ,this wheel is unlike the undershot wheel1 being close boarded round its circumference1 like an overshot or balance wheel1 the undershot wheel being always open2 in short1 it is a sort of bucket wheel2 the buckets1 however1 being constructed differently from those of the overshot and balance wheels4 ,a tide-mill1 as the name imports1 is worked by the ebbing and flowing of the tide4 ,of these mills there are various kinds2 first1 those in which the water wheel turns one way when the tide is rising1 and the other when it is falling2 secondly1 those in which the wheel turns the same way whether it is rising or falling2 thirdly1 those in which the wheel itself rises or falls as the tide flows or ebbs2 and fourthly1 those in which the axle of the water wheel is so fixed1 that it shall neither rise nor fall2 the rotary motion being still given to the wheel1 whether it be partially or wholly immersed in the water4 ,all the machines for grinding corn and seeds are mills1 whatever may be their particular application4 ,one very common form is that of an iron machine1 supported on four legs1 having a winch handle on one side1 a fly wheel on another1 a hopper at the top1 and a crushing apparatus in the centre4 ,the grain or seed is put into the hopper1 the winch handle is turned1 the grain becomes crushed to powder1 and falls out at the bottom of the apparatus4 ,sometimes the mill is made chiefly of wood1 but with iron wheel and crushing apparatus4 ,one kind of wheat mill1 in addition to the usual mill apparatus1 has a chest which acts as a flour-dressing machine4 ,some mills are adapted for crushing beans rather than seeds4 ,the crushing apparatus in mills is of two kinds1 either one stone working round in contact with another1 or two metallic surfaces1 between which the substance is forced1 but between which it cannot pass except in a fine state4 ,the millstones employed in grinding corn require to be made of a peculiar kind of stone4 ,the greater proportion of our millstones are procured from a particular spot in ,western ,germany4 ,at about ten miles from ,coblentz is a small town called ,andernach1 the chief trade of which is in millstones1 procured from the neighbouring quarries of ,nieder ,mendig4 ,there are several quarries1 averaging about fifty feet in depth1 each quarry shaped like an inverted cone1 down the sides of which the quarrymen descend by a spiral path4 ,the quarrymen have to cut away through a superincumbent layer of soft porous stone1 till they come to a layer of hard1 blackish1 heavy stone1 regularly porous1 and yielding sparks when struck with iron4 ,this is the millstone1 and requires good and well-prepared tools to work it2 it is supposed to be a compact lava from some extinct volcano2 and as there are fissures or gaps at intervals1 these facilitate the separation of the stone into blocks suitable for millstones4 ,all round the bottom of the conical cavities1 the stone has been excavated in galleries or horizontal passages4 ,the stones are brought to shape by means of hammers and chisels4 ,a deep socket is cut through the middle of such stones as are intended for runners1 or upper stones4 ,the furrows on the surfaces of the stones are produced by means of a double-edged hammer1 about #ad lbs4 weight4 ,windmills are of two kinds2 in one the wind is made to act upon vanes or sails1 generally four1 which are disposed so as to revolve by that action in a plane which is nearly vertical2 and in the other1 the axis of revolution being precisely vertical1 any point on the surface of a vane revolves in a horizontal plane4 ,the former is called a vertical windmill1 and the latter a horizontal windmill4 ,the building for a vertical windmill is generally a wall of timber or brickwork1 in the form of a frustrum of a cone1 and terminated above by a wooden dome1 which is capable of revolving horizontally upon it4 ,a ring of wood1 forming the lower part of the dome1 rests upon a ring of the same material at the top of the wall1 and the surfaces in contact being made very smooth1 the dome may easily be turned round upon the wall2 and is prevented from sliding off by a rim which projects from it1 and descends over the interior circumference of the lower ring4 ,the dome in turning carries with it the windsails and their axle2 and thus the wind sails may be adjusted to agree with the direction of the wind1 or the plane in which the radii of the sails turn may be made perpendicular to that direction4 ,the revolution is sometimes accomplished by the force of a man applied to a winch near the ground1 but in general the wind itself is made to turn the dome or the mill by means of a set of small vanes1 which are situated at the extremity of a long horizontal arm projecting from the dome1 in a plane passing through the vertical shaft of the mill1 and on the side opposite to the great sails4 ,a horizontal windmill is a great cylindrical frame of timber1 which is made to revolve about an upright centre1 and its convex surface is formed of boards attached in vertical positions to the upper and lower parts of the frame4 ,the whole is enclosed in a fixed cylinder having the same upright centre as the other2 this consists of a revolving screen or a number of boards1 which are so disposed that in whatever direction the wind may blow1 it may enter between them on one side only of a vertical plane1 passing through the axis1 and thus give motion to the interior cylinder4 ,the effective power of the vertical windmill is1 however1 so much greater than that of the horizontal windmill1 that the latter is now seldom constructed4 ,illustration3 ,dressing ,machine or ,bolter4 ,jack4 ,the dressing machine consists of a hollow cylinder1 or frame1 covered with wire cloth of different degrees of fineness1 the finest being at the elevated1 or upper end of the cylinder1 which is inclined in the same way as the bolting mill4 ,within the cylinder1 which may be made of pieces of wood rendered circular1 and1 like the ribs of an animal1 placed at certain distances from each other1 a reel is placed with its axle in the centre of the cylinder1 which is fixed1 or stationary4 ,to the rails of this reel are attached hair brushes1 which1 when made to revolve1 or turn round1 brush against the interior cloth wire surface of the cylinder4 ,the machine is provided with a shoe or jigger1 very similar to that of the millstones1 to cause a regular supply of flour or meal in the same state in which it came from the millstones through a spout from the floor above1 to which it is elevated by the sack tackle1 or elevator1 after being ground4 ,the meal by this means being gradually let1 or fed into the cylinder1 is1 by the motion of the brushes of the reel1 sifted or rubbed through the cloth wire with which the cylinder is covered4 ,the finest of the flour will go through the upper end1 where the finest wire cloth is placed2 the next finest through the next division of the wire cloth1 which is coarser1 the middlings through the following division1 the pollard1 or sharps1 through the last1 and the bran1 not being able to get through the wire cloth at all1 on account of its coarseness1 is thrown out at the end of the cylinder4 ,the cylinder is enclosed in a large and close box1 to prevent the waste of flour by its going off in dust4 ,this box is divided into several compartments1 or partitions1 by means of moveable boards4 ,some millers have more partitions than others1 and indeed they all vary the number to suit the nature or sort of flour which they are manufacturing4 ,in a dressing machine of three divisions1 the flour deposited in the first is called household1 or seconds1 that in the second middlings1 and in the third pollard1 which is not flour1 but a fine description of bran4 ,illustration3 ,revolving ,screen4 ,jacob's ,ladder4 ,when wheat arrives at a mill to be ground the sacks are received in the lower part of the mill1 and hoisted by means of the sack tackle to the upper storeys1 generally the uppermost4 ,the mode of this operation is as follows1 and it is performed with little bodily labour4 ,the rope or chain of the sack tackle is firmly fastened round the mouth of the sack by the man below1 who by means of a rope attached to a lever throws the tackle into gear4 ,the sack then immediately ascends1 without any further aid from the man1 through the different trap doors1 till it has arrived at the place of its destination4 ,there another man is ready to receive it1 who1 as soon as he has landed it by pulling it on one side1 throws the tackle out of gear1 and returns the rope or chain to the man below4 ,the wheat is then shot into a garner or bin1 and thus the same process goes on till the whole load or cargo is safely deposited in the bin or garner4 ,the wheat remains there till it is wanted to be ground1 when1 by means of a spout1 it is conveyed to the hoppers below1 and from thence runs in between the stones4 ,in its progress to the stones1 it may1 or may not1 be subjected to a cleansing process4 ,the wheat being reduced to a flour1 escapes through an aperture of the floor into a spout1 by which it is conveyed to the trough4 ,it is then either put into sacks1 and drawn up again into one of the higher storeys1 and deposited in bins over the dressing machines1 or this is effected by a machine called an elevator1 which performs the operation without the assistance of manual labour4 ,in this bin the flour should be left till1 at any rate1 it is perfectly cold1 but is will be all the better if it remain for three or four weeks1 provided it be occasionally turned4 ,from this bin it is passed1 by means of a spout1 to the hopper of the bolting mill or dressing machine1 by which it is separated from the bran or pollard1 and is then fit for use4 ,illustration3 ,smutter4 ,scoop4 ,claw4 ,the screening machine consists of a roller-shaped sieve1 so divided1 that the corn which is placed at one end passes over a large surface of wire as the sieve revolves1 and this operation removes from it external impurities1 such as sand and dirt4 ,when it arrives at the end of the screw the wheat falls into a hopper1 by which it is conveyed by spouts into small hoppers1 placed over one side of each pair of millstones4 ,from these hoppers there are spouts placed in nearly a horizontal line1 which spouts conduct the corn from the hoppers to the eye of the millstone4 ,they are attached to the hopper1 so as to admit of a horizontal motion1 which is effected by a projecting part of the axle or spindle of the stone1 called a damsel4 ,it is shaped like a cross1 so that1 by the revolution of the millstone1 it keeps tapping the end of the spout1 and gives a rapid vibratory motion to it1 which causes a regular supply of corn to enter the eye of the stone2 by the action of the stones the corn is reduced to flour1 which passes1 by means of spouts1 into the troughs on the ground floor4 ,illustration3 ,scales and ,weights4 ,troughs4 ,the troughs in which the flour is kept2 the scoop and scales for weighing small quantities2 the claw for moving and the steelyard for weighing sacks1 are the other principal objects seen in a mill4 ,jacob's ladder is the name given to a revolving band fitted with a number of leathern cups4 ,these revolve with the band through the flour and serve to carry it up a shaft from one floor to another4 ,illustration3 ,steelyard4 ,,the ,,baker4 ,illustration3 ,,baking ,,oven ,,and ,,kneading ,,trough4 ,of all the trades that are carried on in large towns there is none more important than that of the ,baker4 ,in some parts of the country1 where people make their own bread at home1 or at all events have all the materials for making it1 and know how to mix the different ingredients1 it is of less consequence2 but only imagine what would be our dismay in ,london1 if we got up some morning and heard that all the bakers had agreed not to send in the rolls for breakfast1 and that we must be satisfied to live upon puddings and vegetables until they set to work again to make bread4 ,and yet1 in the early part of their history1 several nations of which we read at school had no knowledge of the trade of a ,baker4 ,until they discovered the art of making proper bread1 and somebody showed them the use of an oven1 the ,romans made their meal into a sort of porridge1 or knew no better than to mix it into flat cakes1 which they cooked on hot stones or in the wood ashes of their fires4 ,the ,anglo-,saxons were a little better off1 for they mixed leaven with their dough1 to make the cakes lighter and better2 but you will remember--by the story of ,king ,alfred1 who when he was in disguise and going to watch the ,danish camp1 was left in the neatherd's hut to watch the cooking of the cakes--that they were baked in the embers of burnt wood upon the hearth4 ,in many parts of ,europe they still use a sort of cake-bread or rolls instead of loaves2 and in some parts of northern ,germany and ,russia the bread of the peasants is nearly black1 and is so coarse and sour that few ,english people could eat it1 especially as it is kept till it grows quite hard1 and sometimes has to be cut with a saw4 ,the ,eastern nations understood the use of ovens1 however1 and the ,jews especially were very good ,bakers1 as were probably the ,egyptians1 for we read of ,pharaoh's ,baker1 whose dream ,joseph interpreted4 ,the trade of baking was held in very high esteem amongst the nations of antiquity1 and included not only the making of bread1 but of those cakes and sweetmeats of which all ,oriental people1 and some ,european people too1 are so fond4 ,by reading the history of the ,jews and the ,egyptians we learn that fermented or leavened bread was in common use amongst them1 at a very early period of their history1 so that the pulse-eating people1 or the people of ,europe who could only eat grain made into porridge1 or simply cooked1 were for a long time behind the ,orientals in this respect4 ,it was not till #fjj years after the establishment of the ,roman state that a public bakery was opened in ,rome itself1 and before this time1 which was about #afg years before the birth of ,christ1 all the baking and bread making was done1 amongst the rest of the family cooking1 in the kitchens of private houses4 ,when the public bakeries were established1 however1 those who followed the trade were held in great respect1 and a code of laws was made to regulate the manner in which their business should be conducted4 ,the same importance was given to the trade in ,england1 when ,bakers first set up business in the large towns1 and people began to buy their loaves instead of making them at home4 ,the early statutes and laws place ,bakers above mere handicraftsmen1 and ranked them with gentlemen1 and very severe punishments were inflicted on fraudulent ,bakers1 who neglected to mark their loaves so that 8wheaten0 bread might be distinguished from 8household20 the same laws condemned that ,baker to the pillory who gave short weight1 even by so much as the fraction of an ounce1 and the bakehouses were placed under the control of the magistrates4 ,there are many people who think that some such stringent laws might be usefully employed now1 and there can be no doubt that the ,baker has too many opportunities of adulterating his bread1 or sending short weight3 the first seriously injuring the health1 and the second the pockets1 of his customers4 ,one of the worst features of the ,baker's trade in our time1 however1 is the dirty condition of the bakehouses and places where bread is made1 the filthy habits which such places give rise to1 and the very long hours during which journeymen ,bakers are at work4 ,all these matters have lately been made the subject of inquiry1 and it may be hoped that they will be greatly improved4 ,illustration3 ,egg ,whisk4 ,flour ,basket and ,scoop4 ,egg ,brush4 ,illustration3 ,sieve4 ,brush4 ,rasp4 ,cleaning ,net4 ,paste ,cutter4 ,biscuit ,marker4 ,knife4 ,iron ,peel4 ,wooden ,peel4 ,the tools that are used in most bakeries are1 beside the oven1 where the bread is baked1 and the kneading trough1 in which the dough is mixed3 a seasoning tub for mixing other ingredients to be mingled with the dough1 a wire sieve for sifting the flour1 and a seasoning sieve made of tin pierced with small holes2 a flour basket lined with tin1 and a flour scoop1 a pail1 a bowl1 a salt-bin1 which should be near the oven1 a yeast tub1 a dough knife1 scales and weights for weighing the dough before it is moulded into a loaf1 a scraper for removing the dough from the trough and the board where the loaves are shaped1 wooden and iron peels1 a sort of shovels with long handles1 for placing the bread in the oven or removing loaves1 dishes and cakes1 after they are baked1 a rasp1 like a coarse broad file with a bent handle1 for rasping off any portion of burnt crust2 a dusting brush for sweeping away refuse of flour or dust from the boards where the loaves are made or placed after baking1 an egg whisk for beating eggs used in pastry1 and an egg brush for putting a glazing of egg on the outside of buns or cakes1 differently shaped tins or moulds for rolls or other articles of fancy bakery1 coarse squares of baize or flannel for covering the dough or the newly-made bread1 and a scuttle1 swabber1 or cleaning net1 made of a quantity of rough netting fastened on the end of a pole1 and which1 after being wetted1 is used for the final removal of all dirt from the oven just before 8setting the batch10 or placing the loaves for baking4 ,beside these there are in most bakehouses set ups1 or oblong pieces of beech wood1 to be placed in the oven for the purpose of keeping the loaves in their places4 ,illustration3 ,tin for ,french ,rolls4 ,tin for ,sponge ,cakes4 ,illustration3 ,scales and ,weights4 ,it would be impossible to give instructions here how to make the various sorts of bread1 but the ordinary kind sold by ,london ,bakers is made much in the following way3-- ,suppose that the ,baker desires to make up a sack of flour2 he empties it into the kneading trough1 and then proceeds to sift it1 in order to make it lie more lightly and to break up any lumps4 ,he then takes from eight to ten pounds of potatoes and boils them1 without removing the skins1 afterwards mashing them in the seasoning tub1 with about half the quantity of flour1 and adding a couple of pails of water4 ,to this mixture he pours about two quarts of yeast1 made from the liquor of boiled hops1 malt1 and patent yeast already made and sold for the purpose4 ,this is the leaven1 which makes the difference between bread and meal-cake1 or the ,english loaf and the ,australian 8damper10 which is made only of flour and water1 and baked at a bush fire2 the yeast or leaven is1 in fact1 meal in its early state of decomposition4 ,this mixture then is left in the seasoning tub1 covered with a sack for several hours1 and allowed to ferment4 ,then the ,baker separates about a quarter of the flour in the trough by means of a board1 and piles it up at one end apart from the larger quantity1 and it is upon this that he pours the contents of the seasoning tub1 taking care that it passes through a sieve placed on a couple of sticks across the trough4 ,this portion upon which the liquor has been poured is called the sponge1 and he proceeds to 8set it0 by thoroughly mixing1 and finally giving it a dust of flour at the top1 after which it is kept for five or six hours1 or until it has twice 8risen10 or puffed out by means of the fermenting liquor within it4 ,just as it has risen a second time1 and air bubbles are breaking through it to the surface1 about three more pailfuls of water are poured upon it1 and in this water about three pounds of salt have been dissolved2 this is well mixed with the sponge1 and then1 the board being removed1 the sponge and the rest of the flour is worked into one mass4 ,it is this kneading and breaking up the sponge which is the hard labour of the ,baker1 and that it is hard labour may be known from the fact that he works nearly naked1 and that1 as he lifts and pummels the tenacious mass1 he heaves great sighs and groans like those with which paviors ram down the stones in the roads4 ,in many of the best bakehouses now a machine is used1 which supersedes this manual labour2 the mass of dough being placed in a cylinder1 within which an axle fitted with bent blades1 or arms of iron1 revolves1 passing through and through the dough as it moves from end to end4 ,by another system 7that of ,dr4 ,dauglish7 the use of yeast is dispensed with1 and the bread1 made by machinery1 is leavened by carbonic acid gas1 which is forced into the cylinder after the atmospheric air is pumped out1 and so goes through the dough and produces the results of fermentation4 ,the dough having been thoroughly mixed in the trough1 is left for an hour or two to 8prove10 and then1 after being sprinkled with flour to prevent its sticking1 is thrown out upon a board1 or the lid of the next trough1 and cut into pieces which are weighed1 and afterwards moulded into loaves4 ,the moulding is only learnt by practice4 ,the piece of dough is cut in half and shaped according to the kind of loaf required1 one piece forming the top of the loaf1 being laid in a hollow of that which is to be the bottom1 and the joint made by a skilful turn of the knuckles4 ,the loaves are placed in the oven by means of the peel1 and are packed at the back and sides as closely as possible1 the cottage bread only being separate1 that it may be crusted all round4 ,the batch takes about two hours to bake4 ,biscuits are now mostly made by machinery1 which in large establishments turns them out ready for the oven2 but when they are wholly or partially made by hand1 the dough is prepared and afterwards moulded into shapes1 and each shape pricked with the docker1 before being placed in the oven4 ,illustration3 ,cornfield4 ,,the ,,sugar ,,refiner4 ,illustration3 ,,boiling ,,house4 ,although sugar was known from very early times1 it was used only in medicine1 and was supposed to be a sort of honey found upon canes in ,india and ,arabia4 ,it is frequently mentioned by the very early writers4 ,the culture of the canes seems to have been confined to the islands of the ,indian ,archipelago1 and the kingdoms of ,bengal1 ,siam1 c4 ,the traffic in sugar was so lucrative that the ,indians concealed the mode of preparing it1 stating to the merchants of ,ormus1 who imported it with gums and spices1 that it was extracted from a reed1 whereupon many unsuccessful attempts were made to find it in the reed-like plants of ,arabia4 ,in #abej the great discoverer1 ,marco ,polo1 visited the country of the sugar cane1 and the merchants afterwards sent to the place of its growth1 instead of buying it at ,ormus4 ,for a long period the use of sugar in ,england was confined to medicines1 or to preparing choice dishes at feasts2 and this continued till #aehj1 when it was brought from ,brazil to ,portugal1 and thence to our country4 ,cultivators distinguish three great varieties of canes--the ,creole1 the ,batavian1 and the ,otaheite4 ,the ,creole cane is indigenous to ,india1 and was transplanted thence to ,sicily1 the ,canary ,isles1 the ,antilles1 ,south ,america1 and to the ,west ,indies4 ,it has dark green leaves1 and a thin but very knotty stem4 ,the ,batavian or striped cane1 which has a dense foliage1 and is covered with purpled stripes1 is a native of ,java1 where it is chiefly cultivated for the manufacture of rum2 it is also met with in some parts of the ,new ,world and the ,west ,indies4 ,the ,otaheite variety grows most luxuriantly1 is the most juicy1 and yields the largest product4 ,it is cultivated chiefly in the ,west ,indies and ,south ,america2 it ripens in ten months1 and is hardier than the other varieties4 ,the sugar cane1 being originally a bog-plant requires a moist1 nutritive soil1 and a hot tropical or sub-tropical climate4 ,it is propagated by slips or pieces of the stem1 with buds on them1 and about two feet long4 ,it arrives at maturity in twelve or sixteen months1 according to the temperature2 the leaves fall off towards the following season1 and the stem acquires a straw-yellow colour4 ,the cane is cut by some planters before the flowering season1 but it is more usual to cut it some weeks after4 ,the plantations are so arranged that the various divisions of the fields may ripen in succession4 ,the land should be supplied with manure rich in nitrogen1 but not containing much saline matter4 ,after the harvest the roots strike again1 and produce a fresh crop of canes2 but in about six years they require to be removed4 ,the time for cutting the canes varies with the soil and season1 and the different varieties of cane4 ,in a state of maturity the canes are from six feet to fifteen feet in length1 and from one and a half inch to two inches in diameter4 ,the usual signs of maturity are a dry1 smooth1 brittle skin1 a heavy cane1 a grey pith1 and sweet and glutinous juice4 ,canes should be cut in dry weather1 or the juice will be found diluted with an excess of water4 ,when cut they are tied up in bundles1 and conveyed to the crushing mill1 particular attention being paid that the supply should not exceed the demand1 otherwise the cut canes would ferment and spoil4 ,the sugar cane grows from pieces or slips of itself1 containing germs1 and these develop rootlets at the joints1 which draw sustenance to the young shoot as it increases4 ,in the course of time the buds in the radicle1 or root-joints of the first cane1 throw out roots1 and form a radicle for a second stem2 and in this way1 under favourable circumstances1 several canes are produced from the parent stock for a period of about six years1 and sometimes for several more4 ,they1 however1 diminish every year in length of joint and circumference1 and are inferior in appearance to the original plant2 but they yield richer juice1 and produce finer sugar4 ,illustration3 ,filtering ,bag4 ,the sugar exists in the cells of the cane in a state of solution1 and is extracted therefrom by pressure4 ,with this1 as with other branches of industry1 science has of late years stepped in1 and has greatly facilitated the process of extraction and manufacture4 ,it may be as well to give here a summary of the processes employed in the preparation of raw sugar3 ,the canes are passed through the mill1 and the juice thus extracted from them runs from the mill into a tank1 whence it is pumped to cisterns for supplying the clarifiers1 heated by steam1 where it is purified4 ,from thence it is run into bag filters1 by which the mechanical impurities are removed4 ,it is then run into charcoal filters to remove the colouring matter of the juice4 ,the filtered juice is then run off into tanks and is drawn thence by vacuum into the vacuum pan1 where it is granulated1 and from whence it is finally discharged for packing4 ,when the steam clarifiers are not employed the cane juice is run into a series of pans or teaches over open fires4 ,this apparatus is also known as a 8battery10 and forms another method of purification4 ,illustration3 ,stirring ,rod4 ,ladle4 ,scraper4 ,crowbar ,wrench4 ,the original crushing apparatus of ,india was a kind of squeezing mortar1 made out of the hollow trunk of a tamarind tree1 and worked by a yoke of oxen1 the pestle or stamper being a strong beam eighteen feet long1 and rounded at the bottom so as to squeeze or crush the canes in the mortar4 ,mills similar to those used for crushing oil seeds were used--as were also several other forms of apparatus--before rollers were introduced4 ,stone and iron rollers were first used1 with the axes in a vertical position1 but the horizontal was soon found to be the more convenient and economical4 ,the importance of a systematic mechanical arrangement appears to have awakened attention during the reign of ,charles the ,second1 for in #affc1 ,lord ,willoughby and ,lawrence ,hyde 7second son of ,edward1 ,earl of ,clarendon1 ,high ,chancellor of ,england7 associated themselves with one ,david de ,marcato1 an inventor1 and obtained a patent for twenty-one years for making and framing sugar mills4 ,in #afia1 ,john ,tizack patented an engine for milling sugar canes1 c42 but in this1 as in the previous case1 it is not specified how the mill should be made4 ,later on in #agba1 ,william ,harding1 a smith1 of ,london1 who had been many years in ,jamaica1 and was skilled in the manufacture of sugar mills1 having observed their imperfections1 how that they were chiefly made with large wooden cogs cased with iron1 endeavoured while abroad to improve their construction1 but failed for want of competent workmen4 ,on his return to ,london he made models of sugar mills which were approved by the ,royal ,society4 ,these mills were fitted with cast iron rollers and cog wheel gearing1 and were worked by water power2 from description they appear to be the type of mills of the present day4 ,some forty-five years later1 ,yonge and ,barclay1 ironfounders1 of ,allhallowslane1 ,city1 applied friction wheels to sugar mills4 ,in #aggc1 ,john ,fleming1 a mill carpenter1 proposed an arrangement of windmill sails which turned a vertical timber shaft shod with iron1 and which gave motion to two hard wooden rollers1 between which the cane was guided and squeezed4 ,in #ahjg1 ,h4 ,c4 ,newman1 of ,st4 ,christopher1 ,west ,indies1 designed a mill to be worked by horse power4 ,he used cog and crown wheels to give motion to three upright rollers1 and the arrangement was considered one which greatly augmented the power and execution of this class of machinery4 ,in #ahba1 ,john ,collinge1 of ,lambeth1 improved cast iron sugar mills by casting the rollers on wrought iron shafts1 instead of keying them on1 as previously done4 ,in #ahdj1 ,james ,robinson patented improvements in sugar mills1 which consisted in using four rollers1 one large one and three smaller ones beneath1 placed horizontally1 and gearing by cogs into each other4 ,up to that time three rollers only appear to have been used4 ,he also proposed to use six rollers1 which are fed from an endless band passing over the rollers4 ,he cast the rollers and shafts in one piece1 cored out to admit steam to facilitate the extraction of the juice from the cane during crushing4 ,he also proposed to tin the interior of vacuum pans1 c4 ,various other arrangements have been patented1 but it is unnecessary here to enumerate1 much less to describe1 them4 ,the foregoing examples give an idea of the progress of the subject during nearly two hundred years4 ,the last ten years have seen rapid strides made in improving the make of mills1 and the general arrangement of sugar works4 ,illustration3 ,sparla4 ,trowel4 ,chisel4 ,hammer4 ,loosening ,stove4 ,crowbar ,hammer4 ,scoop for filling ,moulds4 ,cane juice1 as expressed by the mill1 is an opaque1 slightly viscid fluid1 of a dull grey1 olive1 or olive green colour1 and of a sweet balmy taste4 ,the juice is so exceedingly fermentable that1 in the climate of the ,west ,indies1 it would often run into the acetous fermentation in twenty minutes after leaving the mill1 if the process of clarifying were not immediately commenced4 ,the processes followed in the ,west ,indies for separating the sugar from the juice are as follows3 ,the juice is conducted by channels from the mill to large flat-bottomed clarifiers1 which contain from three hundred to a thousand gallons each4 ,when the clarifier is filled with juice1 a little slaked lime is added to it2 and when the liquor in the clarifier becomes hot by a fire underneath1 the solid portions of the cane juice coagulate1 and are thrown up in the form of scum4 ,the clarified juice1 which is bright1 clear1 and of a yellow wine colour1 is transferred to the largest of a series of evaporating coppers or pans1 three or more in number1 in which it is reduced in bulk by boiling2 it is transferred from one pan to another1 and heated until the sugar is brought to the state of a soft mass of crystals imbedded in molasses--a thick1 viscid1 and uncrystallizable fluid4 ,the soft concrete sugar is removed from the coolers into a range of casks1 in which the molasses gradually drains from the crystalline portion1 percolating through spongy plantain stalks placed in a hole at the bottom of each cask1 which act as so many drains to convey the liquid to a large cistern beneath4 ,with sugar of average quality1 three or four weeks is sufficient for this purpose4 ,the liquid portion constitutes molasses1 which is employed to make rum4 ,the crystallized portion is packed in hogsheads for shipment as raw1 brown1 or muscovado sugar2 and in this state it is commonly exported from our ,west ,indian colonies4 ,illustration3 ,besom4 ,lump ,mould4 ,loaf ,mould4 ,the refining of sugar is mainly a bleaching process1 conducted on a large scale in ,england4 ,there are two varieties produced by this bleaching1 viz4 clayed and loaf sugar4 ,for clayed sugar1 the sugar is removed from the coolers into conical earthen moulds called formes1 each of which has a small hole at the apex4 ,these holes being stopped up1 the forms are placed apex downwards in other earthen vessels4 ,the syrup1 after being stirred round1 is left for from fifteen to twenty hours to crystallize4 ,the plugs are then withdrawn1 to let out the uncrystallized syrup2 and the base of the crystallized loaf being removed1 the forme is filled up with pulverized white sugar4 ,this is well pressed down1 and then a quantity of clay mixed with water is placed upon the sugar1 the formes being put into fresh empty pots4 ,the moisture from the clay1 filtering through the sugar1 carries with it a portion of the colouring matter1 which is more soluble than the crystals themselves4 ,by a repetition of this process1 the sugar attains nearly a white colour1 and is then dried and crushed for sale4 ,but loaf sugar is the kind most usually produced by the refining processes4 ,the brown sugar is dissolved with hot water1 and then filtered through canvas bags1 from which it exudes as a clear1 transparent1 though reddish syrup4 ,the removal of this red tinge is effected by filtering the syrup through a mass of powdered charcoal1 and we have then a perfectly transparent colourless liquid4 ,in the evaporation or concentration of the clarified syrup1 which forms the next part of the refining process1 the boiling is effected 7under the admirable system introduced by ,mr4 ,howard7 in a vacuum1 at a temperature of about #adj ,fahrenheit4 ,the sugar pan is a large copper vessel1 with arrangements for extracting the air1 admitting the syrup1 admitting steam pipes1 and draining off the sugar when concentrated4 ,in using the pan a quantity of syrup is admitted1 and an air pump is set to work to extract all the air from the pan1 in order that the contents may boil at a low temperature4 ,the evaporation proceeds1 and when completed the evaporated syrup flows out of the pan through a pipe into an open vessel beneath1 called the granulating vessel1 around which steam circulates1 and within which the syrup is brought to a partially crystallized state4 ,from the granulators the syrup or sugar is transferred into moulds of a conical form1 which were formerly made of coarse pottery1 but are now usually of iron4 ,in these moulds the sugar whitens and crystallizes1 the remaining uncrystallized syrup flowing out at an opening at the bottom of the moulds4 ,this syrup is reboiled with raw sugar1 so as to yield an inferior quality of sugar2 and1 when all the crystallizable matter has been extracted from it1 the remainder is sold as treacle4 ,the loaves of sugar1 after a few finishing processes1 are ready for sale4 ,,the ,,dyer ,,and ,,scourer4 ,illustration3 ,,dyers ,,at ,,work4 ,the trade of the ,dyer may be placed amongst the most ancient of the arts1 and the tools that are used in it are so few that they need scarcely any description1 since almost all the apparatus required are the various coppers1 vats1 and other vessels used for boiling the fabrics to be dyed1 and immersing them completely in the liquors which have been prepared from the dye stuffs1 the proper use of which is the principal secret in the business4 ,with regard to the scouring or cleaning of fabrics1 whether made into garments or not1 the operation consists in applying detergents1 or substances like soap and turpentine1 for removing grease and dirt1 or other liquids which have a detergent property but will not injure the colours2 the use of these1 with a sponge and a hard brush1 is nearly all that is required2 the garment sent to be cleaned being stretched on a frame and dried1 either in the dyer's drying room1 or in some open situation1 where they are least likely to be soiled or spotted4 ,illustration3 ,drying ,room4 ,sponge4 ,hard ,brush4 ,the art of dyeing was practised to a very great extent by the ancient ,egyptians1 ,phnicians1 ,greeks1 and ,romans2 and the island of ,tyre was1 in very early times1 celebrated for a purple dye which was1 perhaps from its costliness1 used for colouring the robes of kings and emperors1 from which practice purple became the imperial colour4 ,illustration3 ,garment ,frame4 ,the art of modern dyeing very greatly consists in the proper use of what are called mordants1 that is1 substances which1 although they do not of themselves produce colour1 so act upon the dyes as to cause them to give an intenser hue to the fabric1 and also serve to make the colour permanent4 ,the modern dyers have obtained several dye drugs unknown to the ancients1 such as cochineal1 quercitron1 ,brazil and logwood1 arnotts1 and indigo1 which was only known to the ,romans as a paint2 but the vast superiority of our dyes must be principally ascribed to the employment of alum and solution of tin mixed with other substances as mordants1 which give depth1 durability1 and lustre to the colours4 ,another improvement in dyeing is the application of metallic compounds1 such as ,prussian blue1 chrome yellow1 and manganese brown1 to textile or woven fabrics4 ,our readers will see from what has been said of mordants how what are called fast colours are obtained1 fast colours meaning colours which will not be affected even by the liquor of the dye bath4 ,another very necessary subject of information in relation to dyeing is the fact that different substances1 such as silk and wool1 will not be equally affected by the dye in which they are placed1 since the particles contained in the composition of these substances have different degrees of what is called affinity1 that is1 they combine in a greater or less degree with the component matter of the dye stuff4 ,illustration3 ,vats and ,copper ,pan4 ,wringing ,machine4 ,we have already said something of the preparation of cotton4 ,the operations to which silk and wool are subjected before being dyed are intended to separate superfluous substances from the animal fibre1 and to make that fibre more easily unite with the colouring particles4 ,silk is scoured by means of being boiled in water and soap1 whereby the animal varnish is removed from the surface2 if intended to be very white1 it is bleached by humid sulphurous acid4 ,wool is first washed in running water to separate its coarse impurities1 and is then freed from the greasy animal matter secreted from the skin of the sheep by means of ammoniacal liquor1 soap and water1 or a solution of soda4 ,it is finally bleached by the fumes of burning sulphur1 or by aqueous sulphuric acid4 ,illustration3 ,dipping ,copper1 ,winch1 ,punching1 c4 ,what are called tinctorial colours1 as distinguished from mordants1 are either simple or compound4 ,the simple are black1 brown or dun1 blue1 yellow1 and red2 the compounds are grey1 purple1 green1 orange1 and others4 ,gall nuts1 pyrolignite of iron1 logwood1 copperas1 and verdigris1 are the chief materials for producing black4 ,walnuts1 sumach1 madder1 cochineal1 cudbear1 acetate of iron1 catechu1 ,brazil wood1 arnotts1 are all employed in producing brown4 ,indigo1 ,prussian blue1 and woad for blue4 ,fustic1 ,persian berries1 quercitron1 turmeric1 and weld for yellow4 ,cudbear1 ,brazil wood1 cochineal1 kermes1 lac1 logwood1 madder1 safflower1 for red2 and various compounds for purple1 green1 orange1 c4 ,illustration3 ,carboy for ,spirits4 ,syphon4 ,puncheon4 ,pole for ,stirring4 ,the dye materials imported from foreign countries are principally cochineal1 fustic1 gum arabic1 gum senegal1 gum animi1 gum copal1 gum tragacanth1 indigo1 lac dye1 shellac1 logwood1 madder1 smalts1 valonia1 yellow berries1 and zaffre4 ,the tools shown in the engravings explain themselves1 and1 as has been already said1 principally consist of the various coppers and vats1 the syphons or tubes by which liquor will flow from one vessel to another1 and the puncheons1 for stirring and thoroughly immersing the articles in the dye stuff4 ,illustration3 ,rail4 ,thermometer and ,measure4 ,measure4 ,,the ,,coppersmith4 ,illustration3 ,,workshop4 ,the very great variety of purposes for which the metal called copper is used1 renders it one of the most valuable productions of this country1 and several very important manufactures would be incomplete without it1 since it is the principal material of which many large vessels are formed1 and is also largely employed as an alloy for other metals4 ,although the metal is sometimes found in a pure or native state1 its most abundant ore is that known as copper pyrites1 of which there are many kinds4 ,the most common yellow copper ore is a very abundant mineral1 found in large quantities in ,cornwall1 ,devon1 and the ,isle of ,anglesea1 and is a compound of about equal parts of copper1 iron1 and sulphur4 ,the mines of ,devon and ,cornwall yield more than three-fourths of the copper obtained in ,england1 or about #aij1jjj tons of ore in a year1 the value of which is above a million sterling4 ,the amount of copper annually obtained in the ,united ,kingdom is about #ae1jjj tons1 worth more than a million and a half of money4 ,about the same quantity is imported into this country from ,chili and ,cuba1 and a very valuable copper ore is also found at the ,burra ,burra mines in ,australia4 ,the copper ores of ,cornwall and other parts of the country are generally shipped to ,swansea1 where coal is abundant1 in order to be separated from the metal4 ,for this purpose the ore is heated to redness1 or roasted in an open furnace1 in order to burn away the sulphur1 and the fumes given out by this process are most pernicious4 ,the ore is afterwards melted several times to separate the other impurities1 which1 when fused1 float like scum on the surface of the liquid metal1 and are then easily removed4 ,copper has a peculiar reddish colour1 and will bear a brilliant polish2 its smell and taste are both disagreeable4 ,it is one of the most malleable of metals1 and can be so readily worked by the hammer that it is beaten out into thin leaves1 which1 under the name of 8,dutch metal10 are employed in ornamenting toys1 c4 in imitation of gilding4 ,it is also so ductile that it can be drawn out into finer wires than any ordinary metal1 except gold1 silver1 and iron1 and its tenacity is so great that a wire one-tenth of an inch in diameter will bear a weight of #age lbs4 ,this wire is very flexible1 and not very elastic1 but when rolled into sheets copper is one of the most elastic1 and when struck one of the most vibratory and loud sounding metals4 ,if taken into the animal system all preparations of copper are violent poisons2 and1 as this metal is directly acted upon by vinegar and other acids1 it should not be employed for making vessels used in cooking or preparing food4 ,the easy malleability of copper allows it to be rolled into thin sheets1 which can easily be hammered into any form that may be desired1 and it is this operation which belongs to the trade of the ,coppersmith4 ,sheet copper is employed in covering the bottoms of ships1 to protect them from the attacks of marine animals2 it is also used for coins1 which are punched out of the sheet of metal and stamped with dies1 and for plates on which pictures are engraved2 the metal being soft enough to yield to the tool of the engraver1 but yet sufficiently hard to resist the pressure necessary to print the picture4 ,as an ingredient in alloys copper is most valuable1 especially in bell metal1 which is composed of three parts of copper and one part of tin2 in bronze1 which is nine-tenths copper and one-tenth tin2 and in ,german silver1 argentine1 nickel silver1 and other alloys used for making forks1 spoons1 dishes1 c4 which are composed of copper1 zinc1 and nickel4 ,these are very beautiful alloys1 closely resembling silver2 but the copper they contain is liable to be partially dissolved by any long exposure to the action of acids4 ,copper is used in small quantities as an alloy for gold and silver both in coinage and in plate1 to give the requisite degree of hardness4 ,gold used for coins1 or what is called standard gold1 is formed of eleven parts of pure gold and one part of copper4 ,being a better conductor of electricity than any other metal1 it is largely employed in the formation of telegraphic wires2 and1 as it is not hard enough to strike fire with flint or grit1 it is used in gunpowder mills and magazines instead of iron4 ,the processes of casting and rolling copper into sheets are so much like those already described in the manufacture of iron that they need not be repeated1 but the trade of the ,coppersmith is distinct from those of the workers in other metals1 though they mostly consist in forming the sheet copper into various shapes and utensils by means of hammers1 of which the smoothing hammer1 the set hammer1 and the riveting hammer1 explain their own uses by their names4 ,illustration3 ,copper ,bit4 ,oval ,wedge4 ,riveting ,hammer4 ,smoothing ,hammer4 ,cob ,hammer4 ,set ,hammer4 ,in manufacturing the large vessels with circular bottoms which are so frequently made of copper1 the metal is first cast in a shape resembling a round spectacle glass1 that is to say1 a flat cake1 thick in the middle and gradually diminishing in thickness towards the edge4 ,it is then subjected to the powerful blows of a tilt hammer1 the beating being principally confined to the centre4 ,the effect of this is not only to reduce the thickness of the copper1 but to cause the disc to turn up at the edges and assume the form of a hollow dish4 ,illustration3 ,punches4 ,hand ,vice4 ,cutting ,punch4 ,spanner4 ,anvil4 ,shears for ,sheet ,copper4 ,hand ,shears4 ,another operation of the ,coppersmith is called planishing1 or hammering the metal until it becomes more dense1 firm1 and tough2 any one who looks at the surface of a large copper vessel will see the marks of the hammer by which it has been planished4 ,it is by the combined operation of casting1 rolling1 hammering1 and planishing1 as well as by the processes of fastening1 either with rivets or with solder1 that nearly all copper articles are made4 ,illustration3 ,plumber's ,iron4 ,iron ,horse4 ,pouncing ,block and ,hammer4 ,of the tools used by the ,coppersmith1 beside those already mentioned1 the principal are punches for cutting or piercing holes1 shears for cutting the sheets of metal1 the spanner for turning heads of screws or nuts1 the anvil1 the blocks and horses for receiving the work in such a position as to operate on any part where the hammer or the punch is required1 and the iron for soldering4 ,there are five different modes of forming copper piping out of sheet metal2 in the first the edges of the sheet1 which is curved round a mandril1 are made to meet without overlapping1 and are joined with hard solder2 in the second they overlap and are united by soft solder2 in the third they overlap and are secured by rivets2 in the fourth the edges are folded one over the other1 and are made close and firm by hammering2 and in the fifth both edges of the pipe are turned back and covered with a strip of sheet metal1 the two edges of which are turned in and hammered down4 ,illustration3 ,wood ,horse4 ,,the ,,gun ,,manufacturer4 ,illustration3 ,,the ,,proof ,,house4 ,by guns1 only muskets1 rifles1 and fowling-pieces are here meant1 since the manufacture of cannons1 to which the term guns is now commonly applied1 is an entirely different business to that of making what are called 8small arms20 the latter including1 in fact1 swords1 pistols1 bayonets1 muskets1 rifles1 and some other implements of war4 ,there are so many varieties of fire arms1 and they are sold at prices varying so greatly1 that it would be almost impossible to give any detailed description of each kind of piece4 ,the finely-finished rifle or sporting gun1 fitted with the last improvements1 breech-loading or otherwise1 and finished with marvellous perfection and accuracy1 is worth four times as many pounds as the common muskets1 made for exportation to ,africa for the use of the natives1 are worth shillings4 ,we may1 therefore1 describe some of the ordinary processes of the gunmaker's trade1 and the various improvements will then be better understood when the reader has an opportunity of seeing finished guns1 in which such improvements may be pointed out to him4 ,the barrels of guns are either plain or twisted2 twisted barrels are made of long and very narrow strips of iron1 one of which1 being moderately heated to increase pliancy1 is wrapped spirally round a cylindrical mandril in such a way as to form a tube1 which may be slipped off the mandril at pleasure4 ,as the rods are not usually made of sufficient length for one to form a barrel1 several are usually joined end to end1 those which form the breech being thicker than those at the muzzle end4 ,by heating and hammering these pieces are welded into a continuous and very strong and tough tube4 ,partially worn iron1 called 8scrap iron10 is best for these purposes4 ,the twisted barrels which are known as 8wire twist0 are formed of narrow rods of iron and steel forged together1 and then rolled out to the proper thinness4 ,damascus barrels are composed of similar metal1 but the rods are twisted on their own centres until the fibres which they contain have from twelve to fourteen turns in an inch by which the rods are doubled in thickness and proportionately reduced in length4 ,two such rods are welded together side by side1 their respective twists being reversed4 ,there are many modes of making twisted barrels1 but these are the most common4 ,after being welded1 the barrels are carefully examined1 and1 if needful1 straightened by a few blows of the hammer4 ,they are then bored in a machine with an angular plug of tempered steel1 which is caused to revolve rapidly within the barrel1 while a stream of water is directed upon the outside to check the heat caused by the tremendous friction4 ,the outside is brought to a smooth surface either by grinding on a large grindstone1 or turning in a lathe4 ,the breech end of the barrel is bored with a screw-thread1 to receive the breech plug1 which closes it at that end4 ,illustration3 ,mandril1 with ,damascus ,barrel in progress4 ,tool for boring ,barrel4 ,testing ,barrel4 ,the barrels are then proved by being fired at the proof-house1 a large building where they are loaded with a charge five times as great as they will have to bear when in use4 ,a great number of barrels are fired at once by laying them upon a strong framework of wood with their touch-holes downwards1 and connected with a train of gunpowder which is ignited outside the building4 ,a heap of sand is piled inside the building1 opposite the muzzles of the barrels to receive the bullets4 ,those which bear this test without injury are marked as perfect4 ,guns used in field sports are often made with two barrels fixed side by side upon one stock4 ,the barrels are made separately1 and each with one flat side1 that they may lie close together4 ,they are secured together by ribs running between them from end to end4 ,the wooden stock upon which the barrel is fixed is generally made of walnut-tree wood4 ,it is first shaped1 and afterwards shod with brass or steel2 the trigger guard and other fittings are let into the wood1 and every part is furnished with the proper screws and fastenings4 ,with regard to the manufacture of rifles and other small arms in general1 the author of the present work some time ago wrote a description of a visit to the factory at ,birmingham known as the ,toledo ,works1 and it may be useful to give an extract from that account of what he saw there4 ,the steel from which the swords are made is supplied in long pieces somewhat tapering at the ends1 and having a square portion in the middle1 which1 being cut through1 leaves material for two blades1 the bisection of the square leaving a shoulder at one end to receive the iron 8tang0 by which the blade is afterwards fixed into the handle4 ,the manufacture of these blades is almost entirely effected by the forgers1 who hammer them into the required shape upon the anvil1 a mould running down the centre of which secures the hollow which in swords extends for about two-thirds of the length from hilt to point4 ,in a little street of smithies the musical clink is being sounded by a score of stalwart arms1 either forging the rough steel into form1 or hammering the formed blade into perfect shape and symmetry1 an operation which requires it to be kept at a certain heat1 lest the embryo blade should be injured in the process4 ,once perfected as to proportion1 the hardening commences1 and the blade is thrust backwards and forwards into the furnace until it has acquired a proper and uniform heat1 at which point it is removed and instantly plunged into cold water4 ,this process1 which has obviously suggested the ,turkish bath1 renders it hard indeed1 but at the same time so extremely brittle that we whisperingly suggest the propriety of contracting to supply our enemies with weapons1 and neglecting to carry them beyond that particular stage of preparation1 when they may be snapped with the fingers4 ,carefully supported1 however1 the blade is again subjected to the fiery ordeal until it attains a slaty blue colour1 and a beautiful and elastic temper1 which has been partially secured by the previous hammering4 ,by the process of forging it has become about six inches longer than the pristine steel shape1 and by the tempering it has attained a springy strength which enables it to be bent in a curve sufficient to bring the hand five inches nearer to the point than when the blade is straight4 ,many of the best bayonets are forged in the same way as the sword-blades1 and1 as in almost every manufacturing process1 human intelligence has an unmistakable advantage over mere mechanical force1 these possess some superior qualities4 ,the greater number of bayonets1 however1 are made from a square bar of drawn steel1 five inches and a half long by nine-sixteenths square4 ,this bar is passed between a series of about sixteen pairs of rollers1 which are worked by steam power1 and so grooved as gradually to mould the blade to the required shape4 ,sixteen times the short steel bar undergoes the merciless pressure of a progressively-increased power1 until its length is increased from five and a half to twenty-six inches1 when some portion is cut off from the point to leave it the regulation length4 ,the matchets1 which are made from bevel-edged steel1 passed twice through the rollers1 are cut into the requisite shape by means of powerful shears4 ,illustration3 ,steam ,hammer4 ,these operations are conducted in a large shed1 where the rollers stand like awful combinations of infernal machines and patent mangles2 where a boding and vengeful tilt-hammer1 worked by steam1 is tended by a man1 who sits like a calm fate beside its crushing bulk1 and supplies it with fresh victims2 where the awful boom seems to shatter the very atmosphere1 and deafness reigns triumphant4 ,in obedience to a signal1 however1 the monster is suddenly stopped1 and we are enabled to hear that the great two-pot furnace on our left is used for making the steel from those long laths of bevel-edged iron stacked against the wall2 that the furnace is constructed with wide flues on each side and under the bottom1 while the fire-grate occupies the centre between the two pots2 that the pots themselves are some four feet deep1 and two feet and a half wide1 are airtight1 contain layers of charcoal and iron covered with loam sand1 will remain seven days and nights in the furnace1 until their contents are white hot1 and that at the end of that time the iron will have been converted into steel of a slaty-blue colour4 ,the inexorable hammer resuming its work at this point1 we follow the bayonet to its completion1 and once more visit the forges1 to witness the 8shutting on0 or welding the blade to a piece of iron1 which ultimately forms the socket by which the bayonet itself is fixed on to the barrel of the rifle or musket4 ,there is yet another operation before the blades are taken to the finishing shop1 one of the most important1 too1 since it is no other than grinding1 a process which secures an exact and uniform thickness and increases their elasticity4 ,we are standing at the open end of a long1 vast1 and gloomy shed-like building1 supported by iron pillars4 ,on each side through the entire length a series of enormous grindstones spin round amidst sand and water1 and the mud from both4 ,seated astride the bodies of wooden horses1 whose heads seem to have been transformed into these wheels1 the grinders seize upon the blades1 and each fearless rider rising in his stirrups1 or1 what looks much the same1 standing tiptoe till he no longer touches his saddle1 throws himself forward1 and presses the sword1 matchet1 or bayonet on the wheel1 at the same time guiding it deftly with its left hand1 till its whole surface has been smoothly ground4 ,along the whole line of whirling stones fly the lurid red sparks1 and the grinders1 with squared elbows1 seem to curb the struggling and impetuous wheels4 ,after polishing1 which is completed by wooden wheels bearing a coating of leather covered with emery1 the swords and matchets go to receive handles1 and the bayonets locking rings4 ,the handles of swords are made of walnut-wood covered with the skin of the dogfish1 while the hilt and guard are formed from a plain flat sheet of steel1 in shape not unlike one side of a pair of bellows4 ,the solid socket of the bayonet is hammered into form1 and afterwards stamped into shape with the rim complete1 from which process it is conveyed to a shop where it is drilled by steam power4 ,it then only remains to secure a smooth surface1 by means of a revolving barrel1 containing an instrument with a number of flanged blades1 against which the socket of the bayonet is pressed4 ,it is not a little remarkable to see the solid steel pared and shaved like wax1 and no less wonderful to notice the simple machinery by which it is accomplished4 ,the locking rings are stamped out by a lever and die1 pierced by a punch1 and afterwards 8bored10 8faced10 and their shapes secured by a triple circular saw1 worked by a lathe4 ,illustration3 ,mandril1 with ,common ,musket ,barrel in progress4 ,welding by ,hand4 ,forging ,hammer4 ,the most important manufacture in the ,toledo ,works1 however1 is assuredly rifles1 and1 with the intention of following it through its principal processes1 we return to the vicinity of the still inveterate hammer1 where we are shown a rudimentary barrel in the shape of a slab of best wrought iron1 twelve inches long1 and weighing nine pounds and a quarter4 ,this uninviting slab is heated in a furnace1 and roughly bent into the tubular shape by means of our enemy the tilt-hammer1 after which it is once more placed in a furnace of an enormously high temperature1 with a small trap-opening4 ,when sufficiently heated1 the short rudimentary tube is taken out on a long round iron rod1 fitted with a hand-guard1 and looking like a huge burlesque rapier4 ,this rod approximates to the size of the intended bore of the barrel1 and is inserted1 with the rough tube upon it1 between two steam rollers1 each of which is furnished with a series of corresponding grooves or cuts4 ,the barrel1 which is taken up at one end by a rod1 is placed between the first pair of grooves1 and1 as the rollers revolve1 is drawn out at the other side1 a long1 hollow1 welded tube4 ,this much more graceful and better formed tube is then consigned to another rod of smaller diameter1 and to a corresponding pair of grooves2 until1 after the eighth repetition of the same process1 the barrel has attained its proper dimensions4 ,the next operation1 which is called 8lumping10 consists of welding a piece of wrought iron on to the breech end of the barrel1 for the purpose of forming the percussion-lump1 and is succeeded by 8rough-boring40 ,this is accomplished by a long1 sharp-ended bit1 which1 being placed in the end of the barrel1 revolves at the rate of1 perhaps1 a thousand turns a minute by means of a pulley and fly-wheel1 while the barrel is pushed on by a lever1 and kept cool by means of water thrown upon its surface4 ,the 8setting0 of the barrel is next effected by means of hammer and anvil1 the setting meaning simply rectifying any bend which it may have received during the previous operation4 ,we are not a little interested in the setting1 since the first intimation of it on entering the shop is the sudden discovery of a number of workmen gazing resolutely at an opposite window1 through what look like attenuated telescopes4 ,they are engaged1 however1 in one of the processes which require the greatest experience1 as each of them is expected to detect the most trifling bias in the barrel4 ,the 8spilling-up10 or cutting the inside of the barrel to the proper bore1 is similar to the rough-boring1 except that only one edge of the bit is allowed to operate1 the others being sheathed by a half cylinder of wood1 called a spill2 this ensures a smooth surface1 and prepares for the 8fine-boring10 which is six times repeated1 the final surface being insured by keeping one edge of the bit perfectly smooth1 by which means the particles of steel drop in a fine and almost soft powder4 ,the outside of the barrel is next turned in a long lathe1 which not only reduces the roughness1 but1 by a beautiful arrangement of cutting tools1 gives it the required substance or 8pattern10 for a light or heavy rifle4 ,the grinding of the barrels is effected by means of stones1 larger than those used for the sword blades1 but in a similar manner1 and is preliminary to 8filing10 which carries the barrel to the shop1 where it is prepared for the lock4 ,illustration3 ,grinding ,gun ,barrels4 ,these preparations consist of 8chambering10 or making the chamber which holds the pin2 8breeching10 or cutting the worm intended for the breech-pin1 that helps to hold the barrel to the stock by means of a breech-nail2 cutting out the little slice into which the 8sight0 is to be dovetailed2 machining the lump2 filing the tail-pin1 and making the square lump the proper shape for receiving the lock and stock4 ,we are not a little surprised to learn that every part of the lock is finished by hand1 the cock being cut with a die worked by a heavy weight1 and the smaller pieces being wrought with forge1 hammer1 and file4 ,illustration3 ,section of ,breech4 ,section of ,lock1 c4 ,bullet ,mould4 ,nipple ,key4 ,the great art in lock-making is to obtain a perfect spring1 and those properly tempered are so elastic that1 although when fitted in the lock1 the two sides are so close as almost to touch1 they will1 when released1 spread to two inches below the edge of the lock-plate4 ,the lock and barrel are now ready for the stock1 which awaits them in another shop1 where it has been sawn out of walnut wood1 and finished by carpenters' tools4 ,the barrel let into its groove1 and the lock properly in its place1 the stock is more perfectly shaped and rounded before 8screwing together10 or the addition of the different parts of the 8furniture10 heel-plate1 trigger-plate and guard1 trigger1 nose-cap1 rod1 and bayonet4 ,we are now told that the rifle is 8finished10 by which1 understanding completion1 we are not quite prepared to learn that it is to be taken to pieces4 ,we suddenly remember1 however1 that it is not yet a rifle at all1 inasmuch as it has not been rifled4 ,everything is made perfect before this delicate operation is attempted1 in order that no injury may be sustained by the barrel when the complete rifle is again put together4 ,the process of rifling is similar to that of boring1 except that a spiral cutter is substituted for the bit4 ,previous to the reunion of the barrel1 the whole work is polished1 and the stock stained and finished ready for completion4 ,illustration3 8,finishing40 ,the pistol barrels undergo the same processes as that of the rifle1 except that1 after being drilled1 they are planed1 by machines which carry them along a sort of bed under tools that cut them perfectly smooth1 and accurately shape the octagonal barrels4 ,these chisels move by means of screws over the entire surface as it is drawn backwards and forwards on the slide4 ,the revolver chambers are drilled out of solid iron1 by a drilling machine or lathe1 with a centrebit and an eccentric motion1 which causes each barrel of the chamber-nest to become the centre in succession2 while1 by means of a slide1 the motion can be made to suit either a large or small chamber4 ,the recesses communicating with the lock and trigger are cut by reversing the chamber in the eccentric 8chuck10 and using a different cutting-tool1 while another alteration effects the drilling of the nipple holes4 ,,the ,,end ,r4 ,,clay1 ,,son1 ,,and ,,taylor1 ,,printers1 ,,bread ,,street
