as a work of science1 nor as a dry1 chemical treatise1 but as a plain statement of the more simple operations by which nature produces many results1 so common to our observation1 that we are thoughtless of their origin4 ,on these results depend the existence of man and the lower animals4 ,no man should be ignorant of their production4 ,in the early prosecution of the study1 you will find1 perhaps1 nothing to relieve its tediousness2 but1 when the foundation of agricultural knowledge is laid in your mind so thoroughly that you know the character and use of every stone1 then may your thoughts build on it fabrics of such varied construction1 and so varied in their uses1 that there will be opened to you a new world1 even more wonderful and more beautiful than the outward world1 which exhibits itself to the senses4 ,thus may you live two lives1 each assisting in the enjoyment of the other4 ,but you may ask the practical use of this4 ,the world is made up of little things1 saith the proverb4 ,so with the productive arts4 ,the steam engine consists of many parts1 each part being itself composed of atoms too minute to be detected by our observation4 ,the earth itself1 in all its solidity and life1 consists entirely of atoms too small to be perceived by the naked eye1 each visible particle being an aggregation of thousands of constituent elements4 ,the crop of wheat1 which the farmer raises by his labor1 and sells for money1 is produced by a combination of particles equally small4 ,they are not mysteriously combined1 nor irregularly1 but each atom is taken from its place of deposit1 and carried to its required location in the living plant1 by laws as certain as those which regulate the motion of the engine1 or the revolutions of the earth4 ,it is the business of the practical farmer to put together these materials1 with the assistance of nature4 ,he may learn her ways1 assist her action1 and succeed2 or he may remain ignorant of her operations1 often counteract her beneficial influences1 and often fail4 ,a knowledge of the inner world of material things about us will produce pleasure to the thoughtful1 and profit to the practical4

,,chapter ,i4 ,,introduction4 ,what is the object of cultivating the soil8 ,what is necessary in order to cultivate with economy8 ,are plants created from nothing8 ,the object of cultivating the soil is to raise from it a crop of plants4 ,in order to cultivate with economy1 we must raise the largest possible quantity with the least expense1 and without permanent injury to the soil4 ,before this can be done we must study the character of plants1 and learn their exact composition4 ,they are not created by a mysterious power1 they are merely made up of matters already in existence4 ,they take up water containing food and other matters1 and discharge from their roots those substances that are not required for their growth4 ,it is necessary for us to know what kind of matter is required as food for the plant1 and where this is to be obtained1 which we can learn only through such means as shall separate the elements of which plants are composed2 in other words1 we must take them apart1 and examine the different pieces of which they are formed4 ,what must we do to learn the composition of plants8 ,what takes place when vegetable matter is burned8 ,what do we call the two divisions produced by burning8 ,where does organic matter originate8 ,inorganic8 ,how much of chemistry should farmers know8 ,if we burn any vegetable substance it disappears1 except a small quantity of earthy matter1 which we call ashes4 ,in this way we make an important division in the constituents of plants4 ,one portion dissipates into the atmosphere1 and the other remains as ashes4 ,that part which burns away during combustion is called organic matter2 the ashes are called inorganic matter4 ,the organic matter has become air1 and hence we conclude that it was originally obtained from air4 ,the inorganic matter has become earth1 and was obtained from the soil4 ,this knowledge can do us no good except by the assistance of chemistry1 which explains the properties of each part1 and teaches us where it is to be found4 ,it is not necessary for farmers to become chemists4 ,all that is required is1 that they should know enough of chemistry to understand the nature of the materials of which their crops are composed1 and how those materials are to be used to the best advantage4 ,this amount of knowledge may be easily acquired1 and should be possessed by every person1 old or young1 whether actually engaged in the cultivation of the soil or not4 ,all are dependent on vegetable productions1 not only for food1 but for every comfort and convenience of life4 ,it is the object of this book to teach children the first principles of agriculture3 and it contains all that is absolutely necessary to an understanding of the practical operations of cultivation1 etc4 ,is organic matter lost after combustion8 ,of what does it consist8 ,how large a part of plants is carbon8 ,we will first examine the organic part of plants1 or that which is driven away during combustion or burning4 ,this matter1 though apparently lost1 is only changed in form4 ,it consists of one solid substance1 carbon 7or charcoal71 and three gases1 oxygen1 hydrogen and nitrogen4 ,these four kinds of matter constitute nearly the whole of most plants1 the ashes forming often less than one part in one hundred of their dry weight4 ,what do we mean by gas8 ,does oxygen unite with other substances8 ,give some instances of its combinations ,when wood is burned in a close vessel1 or otherwise protected from the air1 its carbon becomes charcoal4 ,all plants contain this substance1 it forming usually about one half of their dry weight4 ,the remainder of their organic part consists of the three gases named above4 ,by the word gas1 we mean air4 ,oxygen1 hydrogen and nitrogen1 when pure1 are always in the form of air4 ,oxygen has the power of uniting with many substances1 forming compounds which are different from either of their constituents alone4 ,thus3 oxygen unites with iron and forms oxide of iron or iron-rust1 which does not resemble the gray metallic iron nor the gas oxygen2 oxygen unites with carbon and forms carbonic acid1 which is an invisible gas1 but not at all like pure oxygen2 oxygen combines with hydrogen and forms water4 ,all of the water1 ice1 steam1 etc41 are composed of these two gases4 ,we know this because we can artificially decompose1 or separate1 all water1 and obtain as a result simply oxygen and hydrogen1 or we can combine these two gases and thus form pure water2 oxygen combines with nitrogen and forms nitric acid4 ,these chemical changes and combinations take place only under certain circumstances1 which1 so far as they affect agriculture1 will be considered in the following pages4 ,as the organic elements of plants are obtained from matters existing in the atmosphere which surrounds our globe1 we will examine its constitution4 ,,chapter ,,ii4 ,,atmosphere4 ,what is atmospheric air composed of8 ,in what proportions8 ,what is the use of nitrogen in air8 ,does the atmosphere contain other matters useful to vegetation8 ,what are they8 ,atmospheric air is composed of oxygen and nitrogen4 ,their proportions are1 one part of oxygen to four parts of nitrogen4 ,oxygen is the active agent in the combustion1 decay1 and decomposition of organized bodies 7those which have possessed animal or vegetable life1 that is1 organic matter71 and others also1 in the breathing of animals4 ,experiments have proved that if the atmosphere consisted of pure oxygen every thing would be speedily destroyed1 as the processes of combustion and decay would be greatly accelerated1 and animals would be so stimulated that death would soon ensue4 ,the use of the nitrogen in the air is to dilute the oxygen1 and thus reduce the intensity of its effect4 ,besides these two great elements1 the atmosphere contains certain impurities which are of great importance to vegetable growth2 these are1 carbonic acid1 water1 ammonia1 etc4 ,,carbonic ,,acid4 ,what is the source of the carbon of plants8 ,what is carbonic acid8 ,what is its proportion in the atmosphere8 ,where else is it found8 ,how does it enter the plant8 ,what are the offices of leaves8 ,carbonic acid is in all probability the only source of the carbon of plants1 and consequently is of more importance to vegetation than any other single sort of food4 ,it is a gas1 and is not1 under natural circumstances1 perceptible to our senses4 ,it constitutes about #a_/bejj of the atmosphere1 and is found in combination with many substances in nature4 ,marble1 limestone and chalk1 are carbonate of lime1 or carbonic acid and lime in combination2 and carbonate of magnesia is a compound of carbonic acid and magnesia4 ,this gas exists in combination with many other mineral substances1 and is contained in all water not recently boiled4 ,its supply1 though small1 is sufficient for the purposes of vegetation4 ,it enters the plant in two ways--through the roots in the water which goes to form the sap1 and at the leaves1 which absorb it from the air in the form of gas4 ,the leaf of the plant seems to have three offices3 that of absorbing carbonic acid from the atmosphere--that of assisting in the chemical preparation of the sap--and that of evaporating its water4 ,if we examine leaves with a microscope we shall find that some have as many as #agj1jjj openings1 or mouths1 in a square inch2 others have a much less number4 ,usually1 the pores on the under side of the leaf absorb the carbonic acid4 ,this absorptive power is illustrated when we apply the lower side of a cabbage leaf to a wound1 as it draws strongly--the other side of the leaf has no such action4 ,young sprouts may have the power of absorbing and decomposing carbonic acid4 ,what parts of roots absorb food8 ,how much of their carbon may plants receive through their roots8 ,what change does carbonic acid undergo after entering the plant8 ,in what parts of the plant1 and under what influence1 is carbonic acid decomposed8 ,the roots of plants terminate at their ends in minute spongioles1 or mouths for the absorption of fluids containing nutriment4 ,in these fluids there exist greater or less quantities of carbonic acid1 and a considerable amount of this gas enters into the circulation of the plants and is carried to those parts where it is required for decomposition4 ,plants1 under favorable circumstances1 may thus obtain about one-third of their carbon4 ,carbonic acid1 it will be recollected1 consists of carbon and oxygen1 while it supplies only carbon to the plant4 ,it is therefore necessary that it be divided1 or decomposed1 and that the carbon be retained while the oxygen is sent off again into the atmosphere1 to reperform its office of uniting with carbon4 ,this decomposition takes place in the green parts of plants and only under the influence of daylight4 ,it is not necessary that the sun shine directly on the leaf or green shoot1 but this causes a more rapid decomposition of carbonic acid1 and consequently we find that plants which are well exposed to the sun's rays make the most rapid growth4 ,explain the condition of different latitudes4 ,does the proportion of carbonic acid in the atmosphere remain about the same8 ,the fact that light is essential to vegetation explains the conditions of different latitudes1 which1 so far as the assimilation of carbon is concerned1 are much the same4 ,at the ,equator the days are but about twelve hours long4 ,still1 as the growth of plants is extended over eight or nine months of the year1 the duration of daylight is sufficient for the requirements of a luxuriant vegetation4 ,at the ,poles1 on the contrary1 the summer is but two or three months long2 here1 however1 it is daylight all summer1 and plants from continual growth develop themselves in that short time4 ,it will be recollected that carbonic acid constitutes but about #a_/bejj of the air1 yet1 although about one half of all the vegetable matter in the world is derived from this source1 as well as all of the carbon required by the growth of plants1 its proportion in the atmosphere is constantly about the same4 ,in order that we may understated this1 it becomes necessary for us to consider the means by which it is formed4 ,carbon1 by the aid of fire1 is made to unite with oxygen1 and always when bodies containing carbon are burnt with the presence of atmospheric air1 the oxygen of that air unites with the carbon1 and forms carbonic acid4 ,the same occurs when bodies containing carbon decay1 as this is simply a slower burning and produces the same results4 ,the respiration 7or breathing7 of animals is simply the union of the carbon of the blood with the oxygen of the air drawn into the lungs1 and their breath1 when thrown out1 always contains carbonic acid4 ,from this we see that the reproduction of this gas is the direct effect of the destruction of all organized bodies1 whether by fire1 decay1 or consumption by animals4 ,explain some of the operations in which this reproduction takes place4 ,how is it reproduced8 ,furnaces are its wholesale manufactories4 ,every cottage fire is continually producing a new supply1 and the blue smoke issuing from the cottage-chimney1 as described by so many poets1 possesses a new beauty1 when we reflect that besides indicating a cheerful fire on the hearth1 it contains materials for making food for the cottager's tables and new faggots for his fire4 ,the wick of every burning lamp draws up the carbon of the oil to be made into carbonic acid at the flame4 ,all matters in process of combustion1 decay1 fermentation1 or putrefaction1 are returning to the atmosphere those constituents1 which they obtained from it4 ,every living animal1 even to the smallest insect1 by respiration1 spends its life in the production of this material necessary to the growth of plants1 and at death gives up its body in part for such formation by decay4 ,thus we see that there is a continual change from the carbon of plants to air1 and from air back to plants1 or through them to animals4 ,as each dollar in gold that is received into a country permanently increases its amount of circulating medium1 and each dollar sent out permanently decreases it until returned1 so the carbonic acid sent into the atmosphere by burning1 decay1 or respiration1 becomes a permanent stock of constantly changeable material1 until it shall be locked up for a time1 as in a house which may last for centuries1 or in an oak tree which may stand for thousands of years4 ,still1 at the decay of either of these1 the carbon which they contain must be again resolved into carbonic acid4 ,what are the coal-beds of ,pennsylvania8 ,what are often found in them8 ,the coal-beds of ,pennsylvania are mines of carbon once abstracted from the atmosphere by plants4 ,in these coal-beds are often found fern leaves1 toads1 whole trees1 and in short all forms of organized matter4 ,these all existed as living things before the great floods1 and at the breaking away of the barriers of the immense lakes1 of which our present lakes were merely the deep holes in their beds1 they were washed away and deposited in masses so great as to take fire from their chemical changes4 ,it is by many supposed that this fire acting throughout the entire mass 7without the presence of air to supply oxygen except on the surface7 caused it to become melted carbon1 and to flow around those bodies which still retained their shapes1 changing them to coal without destroying their structures4 ,this coal1 so long as it retains its present form1 is lost to the vegetable kingdom1 and each ton that is burned1 by being changed into carbonic acid1 adds to the ability of the atmosphere to support an increased amount of vegetation4 ,explain the manner in which they become coal4 ,how does the burning of coal benefit vegetation8 ,is carbon ever permanent in any of its forms8 ,what enables it to change its condition8 ,thus we see that1 in the provisions of nature1 carbon1 the grand basis1 on which all organized matter is founded1 is never permanent in any of its forms4 ,oxygen is the carrier which enables it to change its condition4 ,for instance1 let us suppose that we have a certain quantity of charcoal2 this is nearly pure carbon4 ,we ignite it1 and it unites with the oxygen of the air1 becomes carbonic acid1 and floats away into the atmosphere4 ,the wind carries it through a forest1 and the leaves of the trees with their millions of mouths drink it in4 ,by the assistance of light it is decomposed1 the oxygen is sent off to make more carbonic acid1 and the carbon is retained to form a part of the tree4 ,so long as that tree exists in the form of wood1 the carbon will remain unaltered1 but when the wood decays1 or is burned1 it immediately takes the form of carbonic acid1 and mingles with the atmosphere ready to be again taken up by plants1 and have its carbon deposited in the form of vegetable matter4 ,give an instance of such change4 ,how do plants and animals benefit each other8 ,describe the experiment with the glass tube4 ,the blood of animals contains carbon derived from their food4 ,this unites with the oxygen of the air drawn into the lungs and forms carbonic acid4 ,without this process1 animals could not live4 ,thus1 while by the natural operation of breathing1 they make carbonic acid for the uses of the vegetable world1 plants1 in taking up carbon1 throw off oxygen to keep up the life of animals4 ,there is perhaps no way in which we can better illustrate the changes of form in carbon than by describing a simple experiment4 ,take a glass tube filled with oxygen gas1 and put in it a lump of charcoal1 cork the ends of the tube tightly1 and pass through the corks the wires of an electrical battery4 ,by passing a stream of electrical fluid over the charcoal it may be ignited1 when it will burn with great brilliancy4 ,in burning it is dissolved in the oxygen forming carbonic acid1 and disappears4 ,it is no more lost1 however1 than is the carbon of wood which is burned in a stove2 although invisible1 it is still in the tube1 and may be detected by careful weighing4 ,a more satisfactory proof of its presence may be obtained by decomposing the carbonic acid by drawing the wires a short distance apart1 and giving a spark of electricity4 ,this immediately separates the oxygen from the carbon which forms a dense black smoke in the tube4 ,by pushing the corks together we may obtain a wafer of charcoal of the same weight as the piece introduced4 ,in this experiment we have changed carbon from its solid form to an invisible gas and back again to a solid1 thus fully representing the continual changes of this substance in the destruction of organic matter and the growth of plants4 ,,chapter ,,iii4 ,,hydrogen1 ,,oxygen ,,and ,,nitrogen4 ,,hydrogen ,,and ,,oxygen4 ,what is water composed of8 ,if analyzed1 what does it yield8 ,how do plants obtain their hydrogen and oxygen8 ,let us now consider the three gases1 hydrogen1 oxygen and nitrogen1 which constitute the remainder of the organic part of plants4 ,hydrogen and oxygen compose water1 which1 if analyzed1 yields simply these two gases4 ,plants perform such analysis1 and in this way are able to obtain a sufficient supply of these materials1 as their sap is composed chiefly of water4 ,whenever vegetable matter is destroyed by burning1 decay1 or otherwise1 its hydrogen and oxygen unite and form water1 which is parted with usually in the form of an invisible vapor4 ,the atmosphere of course contains greater or less quantities of watery vapor arising from this cause and from the evaporation of liquid water4 ,this vapor condenses1 forming rains1 etc4 ,hydrogen and oxygen are never taken into consideration in manuring lands1 as they are so readily obtained from the water constituting the sap of the plant1 and consequently should not occupy our attention in this book4 ,,nitrogen4 ,if vegetable matter be destroyed1 what becomes of these constituents8 ,what is the remaining organic constituent8 ,why is it worthy of close attention8 ,do plants appropriate the nitrogen of the atmosphere8 ,nitrogen1 the only remaining organic constituent of vegetable matter1 is for many reasons worthy of close attention4 #a4 ,it is necessary to the growth and perfection of all cultivated plants4 #b4 ,it is necessary to the formation of animal muscle4 #c4 ,it is often deficient in the soil4 #d4 ,it is liable to be easily lost from manures4 ,although about four fifths of atmospheric air are pure nitrogen1 it is almost certain that plants get no nutriment at all from this source4 ,it is all obtained from some of its compounds1 chiefly from the one called ammonia4 ,nitric acid is also a source from which plants may obtain nitrogen1 though to the farmer of less importance than ammonia4 ,,ammonia4 ,what is the principal source from which they obtain nitrogen8 ,what is ammonia8 ,how is it formed8 ,where does it always exist8 ,how do plants take up ammonia8 ,ammonia is composed of nitrogen and hydrogen4 ,it has a pungent smell and is familiarly known as hartshorn4 ,the same odor is perceptible around stables and other places where animal matter is decomposing4 ,all animal muscle1 certain parts of plants1 and other organized substances1 consist of compounds containing nitrogen4 ,when these compounds undergo combustion1 or are in any manner decomposed1 the nitrogen which they contain usually unites with hydrogen1 and forms ammonia4 ,in consequence of this the atmosphere always contains more or less of this gas1 arising from the decay1 etc41 which is continually going on all over the world4 ,this ammonia in the atmosphere is the capital stock to which all plants1 not artificially manured1 must look for their supply of nitrogen4 ,as they can take up ammonia only through their roots1 we must discover some means by which it may be conveyed from the atmosphere to the soil4 ,does water absorb it8 ,what is spirits of hartshorn8 ,why is this power of water important in agriculture8 ,what instance may be cited to prove this8 ,water may be made to absorb many times its bulk of this gas1 and water with which it comes in contact will immediately take it up4 ,spirits of hartshorn is merely water through which ammonia has been passed until it is saturated4,a ,this power of water has a direct application to agriculture1 because the water constituting rains1 dews1 c41 absorbs the ammonia which the decomposition of nitrogenous matter had sent into the atmosphere1 and we find that all rain1 snow and dew1 contain ammonia4 ,this fact may be chemically proved in various ways1 and is perceptible in the common operations of nature4 ,every person must have noticed that when a summer's shower falls on the plants in a flower garden1 they commence their growth with fresh vigor while the blossoms become larger and more richly colored4 ,this effect cannot be produced by watering with spring water1 unless it be previously mixed with ammonia1 in which case the result will be the same4 ,although ammonia is a gas and pervades the atmosphere1 few1 if any1 plants can take it up1 as they do carbonic acid1 through their leaves4 ,it must all enter through the roots in solution in the water which goes to form the sap4 ,although the amount received from the atmosphere is of great importance1 there are few cases where artificial applications are not beneficial4 ,the value of farm-yard and other animal manures1 depends chiefly on the ammonia which they yield on decomposition4 ,this subject1 also the means for retaining in the soil the ammoniacal parts of fertilizing matters1 will be fully considered in the section on manures4 ,can plants use more ammonia than is received from the atmosphere8 ,on what does the value of animal manure chiefly depend8 ,what changes take place after ammonia enters the plant8 ,may the same atom of nitrogen perform many different offices8 ,after ammonia has entered the plant it may be decomposed1 its hydrogen sent off1 and its nitrogen retained to answer the purposes of growth4 ,the changes which nitrogen undergoes1 from plants to animals1 or1 by decomposition1 to the form of ammonia in the atmosphere1 are as varied as those of carbon and the constituents of water4 ,the same little atom of nitrogen may one year form a part of a plant1 and the next become a constituent of an animal1 or1 with the decomposed dead animal1 may form a part of the soil4 ,if the animal should fall into the sea he may become food for fishes1 and our atom of nitrogen may form a part of a fish4 ,that fish may be eaten by a larger one1 or at death may become food for the whale1 through the marine insect1 on which it feeds4 ,after the abstraction of the oil from the whale1 the nitrogen may1 by the putrefaction of his remains1 be united to hydrogen1 form ammonia1 and escape into the atmosphere4 ,from here it may be brought to the soil by rains1 and enter into the composition of a plant1 from which1 could its parts speak as it lies on our table1 it could tell us a wonderful tale of travels1 and assure us that1 after wandering about in all sorts of places1 it had returned to us the same little atom of nitrogen which we had owned twenty years before1 and which for thousands of years had been continually going through its changes4 ,is the same true of the other constituents of plants8 ,is any atom of matter ever lost8 ,the same is true of any of the organic or inorganic constituents of plants4 ,they are performing their natural offices1 or are lying in the earth1 or floating in the atmosphere1 ready to be lent to any of their legitimate uses1 sure again to be returned to their starting point4 ,thus no atom of matter is ever lost4 ,it may change its place1 but it remains for ever as a part of the capital of nature4 ,,footnotes3 ,a ,by saturated1 we mean that it contains all that it is capable of holding4 ,,chapter ,,iv4 ,,inorganic ,,matter4 ,what are ashes called8 ,how many kinds of matter are there in the ashes of plants8 ,into what three classes may they be divided8 ,what takes place when alkalies and acids are brought together8 ,we will now examine the ashes left after burning vegetable substances4 ,this we have called inorganic matter1 and it is obtained from the soil4 ,organic matter1 although forming so large a part of the plant1 we have seen to consist of four different substances4 ,the inorganic portion1 on the contrary1 although forming so small a part1 consists of no less than nine or ten different kinds of matter4,b ,these we will consider in order4 ,in their relations to agriculture they may be divided into three classes--alkalies1 acids1 and neutrals4,c ,is the character of a compound the same as that of its constituents8 ,give an instance of this4 ,do neutrals combine with other substances8 ,name the four alkalies found in the ashes of plants4 ,alkalies and acids are of opposite properties1 and when brought together they unite and neutralize each other1 forming compounds which are neither alkaline nor acid in their character4 ,thus1 carbonic acid 7a gas17 unites with lime--a burning1 caustic substance--and forms marble1 which is a hard tasteless stone4 ,alkalies and acids are characterized by their desire to unite with each other1 and the compounds thus formed have many and various properties1 so that the characters of the constituents give no indication of the character of the compound4 ,for instance1 lime causes the gases of animal manure to escape1 while sulphate of lime 7a compound of sulphuric acid and lime7 produces an opposite effect1 and prevents their escape4 ,the substances coming under the signification of neutrals1 are less affected by the laws of combination1 still they often combine feebly with other substances1 and some of the resultant compounds are of great importance to agriculture4 ,,alkalies4 ,the alkalies which are found in the ashes of plants are four in number2 they are potash1 soda1 lime and magnesia4 ,,potash4 ,how may we obtain potash from ashes8 ,what are some of its agricultural uses8 ,when we pour water over wood ashes it dissolves the potash which they contain1 and carries it through in solution4 ,this solution is called ley1 and if it be boiled to dryness it leaves a solid substance from which pure potash may be made4 ,potash left exposed to the air absorbs carbonic acid and becomes carbonate of potash1 or pearlash2 if another atom of carbonic acid be added1 it becomes super-carbonate of potash1 or salratus4 ,potash has many uses in agriculture4 #a4 ,it forms a constituent of nearly all plants4 #b4 ,it unites with silica 7a neutral71 and forms a compound which water can dissolve and carry into the roots of plants2 thus supplying them with an ingredient which gives them much of their strength4,d #c4 ,it is a strong agent in the decomposition of vegetable matter1 and is thus of much importance in preparing manures4 #d4 ,it roughens the smooth round particles of sandy soils1 and prevents their compacting1 as they are often liable to do4 #e4 ,it is also of use in killing certain kinds of insects1 and1 when artificially applied1 in smoothing the bark of fruit trees4 ,the source from which this and the other inorganic matters required are to be obtained1 will be fully considered in the section on manures4 ,,soda4 ,where is soda found most largely8 ,what is ,glauber's salts8 ,what is washing soda8 ,what are some of the uses of lime8 ,soda1 one of the alkalies contained in the ashes of plants1 is very much the same as potash in its agricultural character4 ,its uses are the same as those of potash--before enumerated4 ,soda exists very largely in nature1 as it forms an important part of common salt1 whether in the ocean or in those inland deposits known as rock salt4 ,when combined with sulphuric acid it forms sulphate of soda or ,glauber's salts4 ,in combination with carbonic acid1 as carbonate of soda1 it forms the common washing soda of the shops4 ,it is often necessary to render soils fertile4 ,,lime4 ,lime is in many ways important in agriculture3 #a4 ,it is a constituent of plants and animals4 #b4 ,it assists in the decomposition of vegetable matter in the soil4 #c4 ,it corrects the acidity,e of sour soils4 #d4 ,as chloride or sulphate of lime it is a good absorbent of fertilizing gases4 ,how is caustic lime made8 ,how much carbonic acid is thus liberated8 ,how does man resemble ,sinbad the sailor8 ,in nature it usually exists in the form of carbonate of lime3 that is1 as marble1 limestone1 and chalk--these all being of the same composition4 ,in manufacturing caustic 7or quick7 lime1 it is customary to burn the carbonate of lime in a kiln2 by this means the carbonic acid is thrown off into the atmosphere and the lime remains in a pure or caustic state4 ,a ,french chemist states that every cubic yard of limestone that is burned1 throws off ten thousand cubic yards of carbonic acid1 which may be used by plants4 ,this reminds us of the story of ,sinbad the sailor1 where we read of the immense genie who came out of a very small box by the sea-shore1 much to the surprise of ,sinbad1 who could not believe his eyes1 until the genie changed himself into a cloud of smoke and went into the box again4 ,sinbad fastened the lid1 and the genie must have remained there until the box was destroyed4 ,now man is very much like ,sinbad1 he lets the carbonic acid out from the limestone 7when it expands and becomes a gas72 and then he raises a crop1 the leaves of which drink it in and pack the carbon away in a very small compass as vegetable matter4 ,here it must remain until the plant is destroyed1 when it becomes carbonic acid again1 and occupies just as much space as ever4 ,the burning of limestone is a very prolific source of carbonic acid4 ,,magnesia4 ,what do you know about magnesia8 ,what is phosphoric acid composed of8 ,with what substance does it form its most important compound8 ,magnesia is the remaining alkali of vegetable ashes4 ,it is well known as a medicine1 both in the form of calcined magnesia1 and1 when mixed with sulphuric acid1 as epsom salts4 ,magnesia is necessary to nearly all plants1 but too much of it is poisonous1 and it should be used with much care1 as many soils already contain a sufficient quantity4 ,it is often found in limestone rocks 7that class called dolomites71 and the injurious effects of some kinds of lime1 as well as the barrenness of soils made from dolomites1 may be attributed entirely to the fact that they contain too much magnesia4 ,,acids4 ,,phosphoric ,,acid4 ,phosphoric acid4--,this subject is one of the greatest interest to the farmer4 ,phosphoric acid is composed of phosphorus and oxygen4 ,the end of a loco-foco match contains phosphorus1 and when it is lighted it unites with the oxygen of the atmosphere and forms phosphoric acid2 this constitutes the white smoke which is seen for a moment before the sulphur commences burning4 ,being an acid1 this substance has the power of combining with any of the alkalies4 ,its most important compound is with lime4 ,will soils1 deficient in phosphate of lime1 produce good crops8 ,from what source do plants obtain their phosphorus8 ,phosphate of lime forms about #fe per cent4 of the dry weight of the bones of all animals1 and it is all derived from the soil through the medium of plants4 ,as plants are intended as food for animals1 nature has provided that they shall not attain their perfection without taking up a supply of phosphate of lime as well as of the other earthy matters2 consequently1 there are many soils which will not produce good crops1 simply because they are deficient in phosphate of lime4 ,it is one of the most important ingredients of manures1 and its value is dependent on certain conditions which will be hereafter explained4 ,another use of phosphoric acid in the plant is to supply it with a small amount of phosphorus1 which seems to be required in the formation of the seed4 ,,sulphuric ,,acid4 ,what is sulphuric acid composed of8 ,what is plaster8 ,what is silica8 ,why is it necessary to the growth of plants8 ,what compounds does it form with alkalies8 ,sulphuric acid is important to vegetation and is often needed to render soils fertile4 ,it is composed of sulphur and oxygen1 and is made for manufacturing purposes1 by burning sulphur4 ,with lime it forms sulphate of lime1 which is gypsum or 'plaster4' ,in this form it is often found in nature1 and is generally used in agriculture4 ,other important methods for supplying sulphuric acid will be described hereafter4 ,it gives to the plant a small portion of sulphur1 which is necessary to the formation of some of its parts4 ,,neutrals4 ,,silica4 ,how can you prove its existence in corn stalks8 ,what instance does ,liebig give to show its existence in grass8 ,how do we supply silicates8 ,why does grain lodge8 ,what is the most important compound of chlorine8 ,this is sand1 the base of flint4 ,it is necessary for the growth of all plants1 as it gives them much of their strength4 ,in connection with an alkali it constitutes the hard shining surface of corn stalks1 straw1 etc4 ,silica unites with the alkalies and forms compounds1 such as silicate of potash1 silicate of soda1 etc41 which are soluble in water1 and therefore available to plants4 ,if we roughen a corn stalk with sand-paper we may sharpen a knife upon it4 ,this is owing to the hard particles of silica which it contains4 ,window glass is silicate of potash1 rendered insoluble by additions of arsenic and litharge4 ,liebig tells us that some persons discovered1 between ,manheim and ,heidelberg in ,germany1 a mass of melted glass where a hay-stack had been struck by lightning4 ,they supposed it to be a meteor1 but chemical analysis showed that it was only the compound of silica and potash which served to strengthen the grass4 ,there is always enough silica in the soil1 but it is often necessary to add an alkali to render it available4 ,when grain1 etc41 lodge or fall down from their own weight1 it is altogether probable that they are unable to obtain from the soil a sufficient supply of the soluble silicates1 and some form of alkali should be added to the soil to unite with the sand and render it soluble4 ,,chlorine4 ,of what use is chloride of lime8 ,what is oxide of iron8 ,what is the difference between the peroxide and the protoxide of iron8 ,chlorine is an important ingredient of vegetable ashes1 and is often required to restore the balance to the soil4 ,it is not found alone in nature1 but is always in combination with other substances4 ,its most important compound is with sodium1 forming chloride of sodium 7or common salt74 ,sodium is the base of soda1 and common salt is usually the best source from which to obtain both soda and chlorine4 ,chlorine unites with lime and forms chloride of lime1 which is much used to absorb the unpleasant odors of decaying matters1 and in this character it is of use in the treatment of manures4 ,,oxide ,,of ,,iron4 ,oxide of iron1 one of the constituents of ashes1 is common iron rust4 ,iron itself is naturally of a grayish color1 but when exposed to the atmosphere1 it readily absorbs oxygen and forms a reddish compound4 ,it is in this form that it usually exists in nature1 and many soils as well as the red sandstones are colored by it4 ,it is seldom1 if ever1 necessary to apply this as a manure1 there being usually enough of it in the soil4 ,this red oxide of iron1 of which we have been speaking1 is called by chemists the peroxide4 ,there is another compound which contains less oxygen than this1 and is called the protoxide of iron1 which is poisonous to plants4 ,when it exists in the soil it is necessary to use such means of cultivation as shall expose it to the atmosphere and allow it to take up more oxygen and become the peroxide4 ,the black scales which fly from hot iron when struck by the blacksmith's hammer are protoxide of iron4 ,the peroxide of iron is a very good absorbent of ammonia1 and consequently1 as will be hereafter described1 adds to the fertility of the soil4 ,what can you say of the oxide of manganese8 ,how do you classify the inorganic constituents8 ,,oxide ,,of ,,manganese1 though often found in small quantities in the ashes of cultivated plants1 cannot be considered indispensable4 ,having now examined all of the materials from which the ashes of plants are formed1,f we are enabled to classify them in a simple manner1 so that they may be recollected4 ,they are as follows3-- ,,alkalies4 ,,acids4 ,,neutrals4 ,potash4 ,sulphuric acid4 ,silica4 ,soda4 ,phosphoric ,chlorine4 ,lime4 ,oxide of ,iron4 ,magnesia4 ,manganese4 ,,footnotes3 ,b ,bromine1 iodine1 etc41 are sometimes detected in particular plants1 but need not occupy the attention of the farmer4 ,c ,this classification is not strictly scientific1 but it is one which the learner will find it well to adopt4 ,these bodies are called neutrals because they have no decided alkaline or acid character4 ,d ,in some soils the fluorides undoubtedly supply plants with soluble silicates1 as fluoric acid has the power of dissolving silica4 ,thus1 in ,derbyshire 7,england71 where the soil is supplied with fluoric acid1 grain is said never to lodge4 ,e ,sourness4 ,f ,there is reason to suppose that alumina is an essential constituent of many plants4 ,,chapter ,v4 ,,growth4 ,of what does a perfect young plant consist8 ,how must the food of plants be supplied8 ,can carbon and earthy matter be taken up at separate stages of growth1 or must they both be supplied at once8 ,having examined the materials of which plants are made1 it becomes necessary to discover how they are put together in the process of growth4 ,let us therefore suppose a young wheat-plant for instance to be in condition to commence independent growth4 ,it consists of roots which are located in the soil2 leaves which are spread in the air1 and a stem which connects the roots and leaves4 ,this stem contains sap vessels 7or tubes7 which extend from the ends of the roots to the surfaces of the leaves1 thus affording a passage for the sap1 and consequently allowing the matters taken up to be distributed throughout the plant4 ,what seems to be nature's law with regard to this8 ,what is the similarity between making a cart and raising a crop8 ,in the growth of a young plant1 what operations take place about the same time8 ,it is necessary that the materials of which plants are made should be supplied in certain proportions1 and at the same time4 ,for instance1 carbon could not be taken up in large quantities by the leaves1 unless the roots1 at the same time1 were receiving from the soil those mineral matters which are necessary to growth4 ,on the other hand1 no considerable amount of earthy matter could be appropriated by the roots unless the leaves were obtaining carbon from the air4 ,this same rule holds true with regard to all of the constituents required2 ,nature seeming to have made it a law that if one of the important ingredients of the plant is absent1 the others1 though they may be present in sufficient quantities1 cannot be used4 ,thus1 if the soil is deficient in potash1 and still has sufficient quantities of all of the other ingredients1 the plant cannot take up these ingredients1 because potash is necessary to its life4 ,if a farmer wishes to make a cart he prepares his wood and iron1 gets them all in the proper condition1 and then can very readily put them together4 ,but if he has all of the wood necessary and no iron1 he cannot make his cart1 because bolts1 nails and screws are required1 and their place cannot be supplied by boards4 ,this serves to illustrate the fact that in raising plants we must give them every thing that they require1 or they will not grow at all4 ,in the case of our young plant the following operations are going on at about the same time4 ,the leaves are absorbing carbonic acid from the atmosphere1 and the roots are drinking in water from the soil4 ,what becomes of the carbonic acid8 ,how is the sap disposed of8 ,what does it contain8 ,how does the plant obtain its carbon8 ,its oxygen and hydrogen8 ,its nitrogen8 ,its inorganic matter8 ,under the influence of daylight1 the carbonic acid is decomposed2 its oxygen returned to the atmosphere1 and its carbon retained in the plant4 ,the water taken in by the roots circulates through the sap vessels of the plant1 and1 from various causes1 is drawn up towards the leaves where it is evaporated4 ,this water contains the nitrogen and the inorganic matter required by the plant and some carbonic acid1 while the water itself consists of hydrogen and oxygen4 ,thus we see that the plant obtains its food in the following manner3-- ,,carbon4--,in the form of carbonic acid from the atmosphere1 and from that contained in the sap1 the oxygen being returned to the air4 ,,oxygen ,from the elements of the water constituting the sap4 ,,hydrogen4 ,,nitrogen4--,from the soil 7chiefly in form of ammonia74 ,it is carried into the plant through the roots in solution in water4 ,,inorganic ,from the soil1 and only in solution in water4 ,,matter4 ,what changes does the food taken up by the plant undergo8 ,many of the chemical changes which take place in the interior of the plant are well understood1 but they require too much knowledge of chemistry to be easily comprehended by the young learner1 and it is not absolutely essential that they should be understood by the scholar who is merely learning the elements of the science4 ,it is sufficient to say that the food taken up by the plant undergoes such changes as are required for its growth2 as in animals1 where the food taken into the stomach1 is digested1 and formed into bone1 muscle1 fat1 hair1 etc41 so in the plant the nutritive portions of the sap are resolved into wood1 bark1 grain1 or some other necessary part4 ,the results of these changes are of the greatest importance in agriculture1 and no person can call himself a practical farmer who does not thoroughly understand them4 ,,chapter ,,vi4 ,,proximate ,,division ,,of ,,plants1 ,,etc4 ,we have hitherto examined what is called the ultimate division of plants4 ,that is1 we have looked at each one of the elements separately1 and considered its use in vegetable growth4 ,of what do wood1 starch and the other vegetable compounds chiefly consist8 ,are their small ashy parts important8 ,what are these compounds called8 ,into how many classes may proximate principles be divided8 ,of what do the first class consist8 ,the second8 ,what vegetable compounds do the first class comprise8 ,we will now examine another division of plants1 called their proximate division4 ,we know that plants consist of various substances1 such as wood1 gum1 starch1 oil1 etc41 and on examination we shall discover that these substances are composed of the various organic and inorganic ingredients described in the preceding chapters4 ,they are made up almost entirely of organic matter1 but their ashy parts1 though very small1 are 7as we shall soon see7 sometimes of great importance4 ,these compounds are called proximate principles1,g or vegetable proximates4 ,they may be divided into two classes4 ,the first class are composed of carbon1 hydrogen1 and oxygen4 ,the second class contain the same substances and nitrogen4 ,are these substances of about the same composition8 ,can they be artificially changed from one to another8 ,give an instance of this4 ,is the ease with which these changes take place important8 ,from what may the first class of proximates be formed8 ,the first class 7those compounds not containing nitrogen7 comprise the wood1 starch1 gum1 sugar1 and fatty matter which constitute the greater part of all plants1 also the acids which are found in sour fruits1 etc4 ,various as are all of these things in their characters1 they are entirely composed of the same ingredients 7carbon1 hydrogen and oxygen71 and usually combined in about the same proportion4 ,there may be a slight difference in the composition of their ashes1 but the organic part is much the same in every case1 so much so1 that they can often be artificially changed from one to the other4 ,as an instance of this1 it may be recollected by those who attended the ,fair of the ,american ,institute1 in #ahcd1 that ,prof4 ,mapes exhibited samples of excellent sugar made from the juice of the cornstalk1 starch1 linen1 and woody fibre4 ,the ease with which these proximates may be changed from one to the other is their most important agricultural feature1 and should be clearly understood before proceeding farther4 ,it is one of the fundamental principles on which the growth of both vegetables depends4 ,the proximates of the first class constitute usually the greater part of all plants1 and they are readily formed from the carbonic acid and water which in nature are so plentifully supplied4 ,why are those of the second class particularly important to farmers8 ,what is the general name under which they are known8 ,what is the protein of wheat called8 ,why is flour containing much gluten preferred by bakers8 ,can protein be formed without nitrogen8 ,if plants were allowed to complete their growth without a supply of this ingredient1 what would be the result8 ,the second class of proximates1 though forming only a small part of the plant1 are of the greatest importance to the farmer1 being the ones from which animal muscle,h is made4 ,they consist1 as will be recollected1 of carbon1 hydrogen1 oxygen and nitrogen1 or of all of the organic elements of plants4 ,they are all of much the same character1 though each kind of plant has its peculiar form of this substance1 which is known under the general name of protein4 ,the protein of wheat is called gluten--that of ,indian corn is zein--that of beans and peas is legumin4 ,in other plants the protein substances are vegetable albumen1 casein1 etc4 ,gluten absorbs large quantities of water1 which causes it to swell to a great size1 and become full of holes4 ,flour which contains much gluten1 makes light1 porous bread1 and is preferred by bakers1 because it absorbs so large an amount of water4 ,what is the result if a field be deficient in nitrogen8 ,the protein substances are necessary to animal and vegetable life1 and none of our cultivated plants will attain maturity 7complete their growth71 unless allowed the materials required for forming this constituent4 ,to furnish this condition is the object of nitrogen given to plants as manure4 ,if no nitrogen is supplied the protein substances cannot be formed1 and the plant must cease to grow4 ,when on the contrary ammonia is given to the soil 7by rains or otherwise71 it furnishes nitrogen1 while the carbonic acid and water yield the other constituents of protein1 and a healthy growth continues1 provided that the soil contains the mineral matters required in the formation of the ash1 in a condition to be useful4 ,the wisdom of this provision is evident when we recollect that the protein substances are necessary to the formation of muscle in animals1 for if plants were allowed to complete their growth without a supply of this ingredient1 our grain and hay might not be sufficiently well supplied with it to keep our oxen and horses in working condition1 while under the existing law plants must be of nearly a uniform quality 7in this respect71 and if a field is short of nitrogen1 its crop will not be large1 and of a very poor quality1 but the soil will produce good plants as long as the nitrogen lasts1 and then the growth must cease4,i ,,animals4 ,that this principle may be clearly understood1 it may be well to explain more fully the application of the proximate constituents of plants in feeding animals4 ,of what are the bodies of animals composed8 ,what is the office of vegetation8 ,what part of the animal is formed from the first class of proximates8 ,from the second8 ,which contains the largest portions of inorganic matter1 plants or animals8 ,must animals have a variety of food1 and why8 ,animals are composed 7like plants7 of organic and inorganic matter1 and every thing necessary to build them up exists in plants4 ,it seems to be the office of the vegetable world to prepare the gases in the atmosphere1 and the minerals in the earth for the uses of animal life1 and to effect this plants put these gases and minerals together in the form of the various proximates 7or compound substances7 which we have just described4 ,in animals the compounds containing no nitrogen comprise the fatty substances1 parts of the blood1 etc41 while the protein compound1 or those which do contain nitrogen1 form the muscle1 a part of the bones1 the hair1 and other portions of the animal4 ,animals contain a larger proportion of inorganic matter than plants do4 ,bones contain a large quantity of phosphate of lime1 and we find other inorganic materials performing important offices in the system4 ,in order that animals may be perfectly developed1 they must of course receive as food all of the materials required to form their bodies4 ,they cannot live if fed entirely on one ingredient4 ,thus1 if starch alone be eaten by the animal1 he might become fat1 but his strength would soon fail1 because his food contains nothing to keep up the vigor of his muscles4 ,if on the contrary the food of an animal consisted entirely of gluten1 he might be very strong from a superior development of muscle1 but would not be fat4 ,hence we see that in order to keep up the proper proportion of both fat and muscle in our animals 7or in ourselves71 the food must be such as contains a proper proportion of the two kinds of proximates4 ,why is grain good for food8 ,on what does the value of flour depend8 ,is there any relation between the ashy part of plants and those of animals8 ,how may we account for unhealthy bones and teeth8 ,it is for this reason that grain1 such as wheat for instance1 is so good for food4 ,it contains both classes of proximates1 and furnishes material for the formation of both fat and muscle4 ,the value of flour depends very much on the manner in which it is manufactured4 ,this will be soon explained4 ,what is a probable cause of consumption8 ,what is an important use of the first class of proximates8 ,what may lungs be called8 ,explain the production of heat during decomposition4 ,why is the heat produced by decay not perceptible8 ,apart from the relations between the proximate principles of plants1 and those of animals1 there exists an important relation between their ashy or inorganic parts2 and1 food in order to satisfy the demands of animal life1 must contain the mineral matter required for the purposes of that life4 ,take bones for instance4 ,if phosphate of lime is not always supplied in sufficient quantities by food1 animals are prevented from the formation of healthy bones4 ,this is particularly to be noticed in teeth4 ,where food is deficient of phosphate of lime1 we see poor teeth as a result4 ,some physicians have supposed that one of the causes of consumption is the deficiency of phosphate of lime in food4 ,why is the heat produced by combustion apparent8 ,explain the production of heat in the lungs of animals8 ,why does exercise augment the animal heat8 ,under what circumstances is the animal's own fat used in the production of heat8 ,the first class of proximates 7starch1 sugar1 gum1 etc471 perform an important office in the animal economy aside from their use in making fat4 ,they constitute the fuel which supplies the animal's fire1 and gives him his heat4 ,the lungs of men and other animals may be called delicate stoves1 which supply the whole body with heat4 ,but let us explain this matter more fully4 ,if wood1 starch1 gum1 or sugar1 be burned in a stove1 they produce heat4 ,these substances consist1 as will be recollected1 of carbon1 hydrogen1 and oxygen1 and when they are destroyed in any way 7provided they be exposed to the atmosphere71 the hydrogen and oxygen unite and form water1 and the carbon unites with the oxygen of the air and forms carbonic acid1 as was explained in a preceding chapter4 ,this process is always accompanied by the liberation of heat1 and the intensity of this heat depends on the time occupied in its production4 ,in the case of decay1 the chemical changes take place so slowly that the heat1 being conducted away as soon as formed1 is not perceptible to our senses4 ,in combustion 7or burning7 the same changes take place with much greater rapidity1 and the same amount of heat being concentrated1 or brought out in a far shorter time1 it becomes intense1 and therefore apparent4 ,in the lungs of animals the same law holds true4 ,the blood contains matters belonging to this carbonaceous class1 and they undergo in the lungs the changes which have been described under the head of combustion and decay4 ,their hydrogen and oxygen unite1 and form the moisture of the breath1 while their carbon is combined with the oxygen of the air drawn into the lungs1 and is thrown out as carbonic acid4 ,the same consequence--heat--results in this1 as in the other cases1 and this heat is produced with sufficient rapidity for the animal necessities4 ,when an animal exercises violently1 his blood circulates with increased rapidity1 thus carrying carbon more rapidly to the lungs4 ,the breath also becomes quicker1 thus supplying increased quantities of oxygen4 ,in this way the decomposition becomes more rapid1 and the animal is heated in proportion4 ,thus we see that food has another function besides that of forming animal matter1 namely to supply heat4 ,when the food does not contain a sufficient quantity of starch1 sugar1 etc41 to answer the demands of the system the animal's own fat is carried to the lungs1 and there used in the production of heat4 ,this important fact will be referred to again4 ,,footnotes3 ,g ,by proximate principle1 we mean that combination of vegetable elements which is known as a vegetable product1 such as wood1 etc4 ,h ,muscle is lean meat1 it gives to animals their strength and ability to perform labor4 ,i ,this1 of course1 supposes that the soil is fertile in other respects4 ,,chapter ,,vii4 ,,location ,,of ,,the ,,proximates ,,and ,,variations ,,in ,,the ,,ashes ,,of ,,plants4 ,of what proximate are plants chiefly composed8 ,what is the principal constituent of the potato root8 ,of the carrot and turnip8 ,what part of the plant contains usually the most nutriment8 ,let us now examine plants with a view to learning the location of the various plants4 ,the stem or trunk of the plant or tree consists almost entirely of woody fibre2 this also forms a large portion of the other parts except the seeds1 and1 in some instances1 the roots4 ,the roots of the potato contain large quantities of starch4 ,other roots such as the carrot and turnip contain pectic acid1,j a nutritious substance resembling starch4 ,it is in the seed however that the more nutritive portions of most plants exist1 and here they maintain certain relative positions which it is well to understand1 and which can be best explained by reference to the following figures1 as described by ,prof4 ,johnston3-- ,illustration3 ,fig4 #a4 ,thus a shows the position of the oil in the outer part of the seed--it exists in minute drops1 inclosed in six-sided cells1 which consists chiefly of gluten2 b1 the position and comparative quantity of the starch1 which in the heart of the seed is mixed with only a small proportion of gluten2 c1 the germ or chit which contains much gluten4,k ,is the composition of the inorganic matter of different parts of the plant the same1 or different8 ,what is the difference between the ash of the straw and that of the grain of wheat8 ,the location of the inorganic part of plants is one of much interest1 and shows the adaptation of each part to its particular use4 ,take a wheat plant1 for instance--the stalk1 the leaf1 and the grain1 show in their ashes1 important difference of composition4 ,the stalk or straw contains three or four times as large a proportion of ash as the grain1 and a no less remarkable difference of composition may be noticed in the ashes of the two parts4 ,in that of the straw1 we find a large proportion of silica and scarcely any phosphoric acid1 while in that of the grain there is scarcely a trace of silica1 although phosphoric acid constitutes more than one half of the entire weight4 ,the leaves contain a considerable quantity of lime4 ,what is the reason for this difference8 ,in what part of the grain does phosphoric acid exist most largely8 ,this may at first seem an unimportant matter1 but on examination we shall see the use of it4 ,the straw is intended to support the grain and leaves1 and to convey the sap from the roots to the upper portions of the plant4 ,to perform these offices1 strength is required1 and this is given by the silica1 and the woody fibre which forms so large a proportion of the stalk4 ,the silica is combined with an alkali1 and constitutes the glassy coating of the straw4 ,while the plant is young1 this coating is hardly apparent1 but as it grows older1 as the grain becomes heavier1 7verging towards ripeness71 the silicious coating of the stalk assumes a more prominent character1 and gives to the straw sufficient strength to support the golden head4 ,the straw is not the most important part of the plant as food1 and therefore requires but little phosphoric acid4 ,why is ,graham flour more wholesome than fine flour8 ,are the ashes of all plants the same in their composition8 ,the grain1 on the contrary1 is especially intended as food1 and therefore must contain a large proportion of phosphoric acid--this being1 as we have already learned1 necessary to the formation of bone--while1 as it has no necessity for strength1 and as silica is not needed by animals1 this ingredient exists in the grain only in a very small proportion4 ,it may be well to observe that the phosphoric acid of grain exists most largely in the hard portions near the shell1 or bran4 ,this is one of the reasons why ,graham flour is more wholesome than fine flour4 ,it contains all of the nutritive materials which render the grain valuable as food1 while flour which is very finely bolted,l contains only a small part of the outer portions of the grain 7where the phosphoric acid1 protein and fatty matters exist most largely74 ,the starchy matter in the interior of the grain1 which is the least capable of giving strength to the animal1 is carefully separated1 and used as food for man1 while the better portions1 not being ground so finely1 are rejected4 ,this one thing alone may be sufficient to account for the fact1 that the lives of men have become shorter and less blessed with health and strength1 than they were in the good old days when a stone mortar and a coarse sieve made a respectable flour mill4 ,another important fact concerning the ashes of plants is the difference of their composition in different plants4 ,thus1 the most prominent ingredient in the ash of the potato is potash2 of wheat and other grains1 phosphoric acid2 of meadow hay1 silica2 of clover1 lime2 of beans1 potash1 etc4 ,in grain1 potash 7or soda71 etc41 are among the important ingredients4 ,of what advantage are these differences to the farmer8 ,of what are plants composed8 ,these differences are of great importance to the practical farmer1 as by understanding what kind of plants use the most of one ingredient1 and what kind requires another in large proportion1 he can regulate his crops so as to prevent his soil from being exhausted more in one ingredient than in the others1 and can also manure his land with reference to the crop which he intends to grow4 ,the tables of analyses in the fifth section will point out these differences accurately4 ,,footnotes3 ,j ,this pectic acid gelatinizes food in the stomach1 and thus renders it more digestible4 ,k ,see ,johnston's ,elements1 page #da4 ,l ,sifted through a fine cloth called a bolting cloth4 ,,chapter ,,viii4 ,,recapitulation4 ,we have now learned as much about the plant as is

is that which burns away in the fire4 ,inorganic matter is the ash left after burning4 ,the organic matter of plants consists of three gases1 oxygen1 hydrogen and nitrogen1 and one solid substance carbon 7or charcoal74 ,the inorganic matter of plants consists of potash1 soda1 lime1 magnesia1 sulphuric acid1 phosphoric acid1 chlorine1 silica1 oxide of iron1 and oxide of manganese4 ,plants obtain their organic food as follows3--,oxygen and hydrogen from water1 nitrogen from some compound containing nitrogen 7chiefly from ammonia71 and carbon from the atmosphere where it exists as carbonic acid--a gas4 ,they obtain their inorganic food from the soil4 ,the water which supplies oxygen and hydrogen to plants is readily obtained without the assistance of manures4 ,ammonia is obtained from the atmosphere1 by being absorbed by rain and carried into the soil1 and it enters plants through their roots4 ,it may be artificially supplied in the form of animal manure with profit4 ,carbonic acid is absorbed from the atmosphere by leaves1 and decomposed in the green parts of plants under the influence of daylight2 the carbon is retained1 and the oxygen is returned to the atmosphere4 ,when plants are destroyed by combustion or decay1 what becomes of their constituents8 ,how does the inorganic matter enter the plant8 ,are the alkalies soluble in their pure forms8 ,which one of them is injurious when too largely present8 ,how may sulphuric acid be supplied8 ,is phosphoric acid important8 ,how must silica be treated8 ,from what source may we obtain chlorine8 ,when plants are destroyed by decay1 or burning1 their organic constituents pass away as water1 ammonia1 carbonic acid1 etc41 ready again to be taken up by other plants4 ,the inorganic matters in the soil can enter the plant only when dissolved in water4 ,potash1 soda1 lime1 and magnesia1 are soluble in their pure forms4 ,magnesia is injurious when present in too large quantities4 ,sulphuric acid is often necessary as a manure1 and is usually most available in the form of sulphate of lime or plaster4 ,it is also valuable in its pure form to prevent the escape of ammonia from composts4 ,phosphoric acid is highly important1 from its frequent deficiency in worn-out soils4 ,it is available only under certain conditions which will be described in the section on manures4 ,silica is the base of common

they obtain the materials from which to form their growth8 ,oxide of iron is iron rust4 ,there are two oxides of iron1 the peroxide 7red7 and the protoxide 7black74 ,the former is a fertilizer1 and the latter poisons plants4 ,oxide of manganese is often absent from the ashes of our cultivated plants4 ,the food of plants1 both organic and inorganic1 must be supplied in certain proportions1 and at the time when it is required4 ,in the plant1 this food undergoes such chemical changes as are necessary to growth4 ,the compounds formed by these chemical combinations are called proximates4 ,proximates are of two classes1 those not containing nitrogen1 and those which do contain it4 ,the first class constitute nearly the whole plant4 ,the second class1 although small in quantity1 are of the greatest importance to the farmer1 as from them all animal muscle is made4 ,animals1 like plants1 are composed of both organic and inorganic matter1 and their bodies are obtained directly or indirectly from plants4 ,what parts of the animal belong to the first class of proximates8 ,what to the second8 ,what is necessary to the perfect development of animals8 ,why are seeds valuable for working animals8 ,what other important use1 in animal economy1 have proximates of the first class8 ,under what circumstances is animal fat decomposed8 ,the first class of proximates in animals comprise the fat1 and like tissues4 ,the second class form the muscle1 hair1 gelatine of the bones1 etc4 ,in order that they may be perfectly developed1 animals must eat both classes of proximates1 and in the proportions required by their natures4 ,they require the phosphate of lime and other inorganic food which exist in plants4 ,seeds are the best adapted to the uses of working animals1 because they are rich in all kinds of food required4 ,aside from their use in the formation of fat1 proximates of the first class are employed in the lungs1 as fuel to keep up animal heat1 which is produced 7as in fire and decay7 by the decomposition of these substances4 ,when the food is insufficient for the purposes of heat1 the animal's own fat is decomposed1 and carried to the lungs as fuel4 ,the stems1 roots1 branches1 etc41 of most plants consist principally of woody fibre4 ,their seeds1 and sometimes their roots1 contain considerable quantities of starch4 ,name the parts of the plant in which the different proximates exist4 ,state what you know about flour4 ,do we know that different plants have ashes of different composition8 ,the protein and the oils of most plants exist most largely in the seeds4 ,the location of the proximates1 as well as of the inorganic parts of the plant1 show a remarkable reference to the purposes of growth1 and to the wants of the animal world1 as is noticed in the difference between the construction of the straw and that of the kernel of wheat4 ,the reason why the fine flour now made is not so healthfully nutritious as that which contained more of the coarse portions1 is that it is robbed of a large proportion of protein and phosphate of lime1 while it contains an undue amount of starch1 which is available only to form fat1 and to supply fuel to the lungs4 ,different plants have ashes of different composition4 ,thus--one may take from the soil large quantities of potash1 another of phosphoric acid1 and another of lime4 ,by understanding these differences1 we shall be able so to regulate our rotations1 that the soil may not be called on to supply more of one ingredient than of another1 and thus it may be kept in balance4 ,how are farmers to be benefited by such knowledge8 ,the facts contained in this chapter are the alphabet of agriculture1 and the learner should not only become perfectly familiar with them1 but should also clearly understand the reasons why they are true1 before proceeding further4 ,,section ,,second4 ,,the ,,soil4 ,,chapter ,i4 ,,formation ,,and ,,character ,,of ,,the ,,soil4 ,what is a necessary condition of growth8 ,in the foregoing section1 we have studied the character of plants and the laws which govern their growth4 ,we learned that one necessary condition for growth is a fertile soil1 and therefore we will examine the nature of different soils1 in order that we may understand the relations between them and plants4 ,what is a fixed character of soils8 ,how is the chemical character of the soil to be ascertained8 ,what do we first learn in analyzing a soil8 ,how do the proportions of organic or inorganic parts of soils compare with those of plants8 ,of what does the organic part of soils consist8 ,the soil is not to be regarded as a mysterious mass of dirt1 whereon crops are produced by a mysterious process4 ,well ascertained scientific knowledge has proved beyond question that all soils1 whether in ,america or ,asia1 whether in ,maine or ,california1 have certain fixed properties1 which render them fertile or barren1 and the science of agriculture is able to point out these characteristics in all cases1 so that we can ascertain from a scientific investigation what would be the chances for success in cultivating any soil which we examine4 ,the soil is a great chemical compound1 and its chemical character is ascertained 7as in the case of plants7 by analyzing it1 or taking it apart4 ,we first learn that fertile soils contain both organic and inorganic matter2 but1 unlike the plant1 they usually possess much more of the latter than of the former4 ,in the plant1 the organic matter constitutes the most considerable portion of the whole4 ,in the soil1 on the contrary1 it usually exists in very small quantities1 while the inorganic portions constitute nearly the whole bulk4 ,can the required proportion be definitely indicated8 ,from what source is the inorganic part of soils derived8 ,do all soils decompose with equal facility8 ,how does frost affect rocks8 ,does it affect soils in the same way8 ,the organic part of soils consists of the same materials that constitute the organic part of the plants1 and it is in reality decayed vegetable and animal matter4 ,it is not necessary that this organic part of the soil should form any particular proportion of the whole1 and indeed we find it varying from one and a half to fifty1 and sometimes1 in peaty soils1 to over seventy per cent4 ,all fertile soils contain some organic matter1 although it seems to make but little difference in fertility1 whether it be ten or fifty per cent4 ,the inorganic part of soils is derived from the crumbling of rocks4 ,some rocks 7such as the slates in ,central ,new ,york7 decompose1 and crumble rapidly on being exposed to the weather2 while granite1 marble1 and other rocks will last for a long time without perceptible change4 ,the causes of this crumbling are various1 and are not unimportant to the agriculturist2 as by the same processes by which his soil was formed1 he can increase its depth1 or otherwise improve it4 ,this being the case1 we will in a few words explain some of the principal pulverizing agents4 #a4 ,the action of frost4 ,when water lodges in the crevices of rocks1 and freezes1 it expands1 and bursts the rock1 on the same principle as causes it to break a pitcher in winter4 ,this power is very great1 and by its assistance1 large cannon may be burst4 ,of course the action of frost is the same on a small scale as when applied to large masses of matter1 and1 therefore1 we find that when water freezes in the pores,m of rocks or stones1 it separates their particles and causes them to crumble4 ,the same rule holds true with regard to stiff clay soils4 ,if they are ridged in autumn1 and left with a rough surface exposed to the frosts of winter1 they will become much lighter1 and can afterwards be worked with less difficulty4 ,what is the effect of water on certain rocks8 ,how are some rocks affected by exposure to the atmosphere8 ,give an instance of this4 #b4 ,the action of water4 ,many kinds of rock become so soft on being soaked with water1 that they readily crumble4 #c4 ,the chemical changes of the constituents of the rock4 ,many kinds of rock are affected by exposure to the atmosphere1 in such a manner1 that changes take place in their chemical character1 and cause them to fall to pieces4 ,the red kellis of ,new ,jersey 7a species of sandstone71 is1 when first quarried1 a very hard stone1 but on exposure to the influences of the atmosphere1 it becomes so soft that it may be easily crushed between the thumb and finger4 ,what is the similarity between the composition of soils and the rocks from which they were formed8 ,what does feldspar rock yield8 ,talcose slate8 ,marls8 ,does a soil formed entirely from rock contain organic matter8 ,how is it affected by the growth of plants8 ,other actions1 of a less simple kind1 exert an influence on the stubbornness of rocks1 and cause them to be resolved into soils4,n ,of course1 the composition of the soil must be similar to that of the rock from which it was formed2 and1 consequently1 if we know the chemical character of the rock1 we can tell whether the soil formed from it can be brought under profitable cultivation4 ,thus feldspar1 on being pulverized1 yields potash2 talcose slate yields magnesia2 marls yield lime1 etc4 ,the soil formed entirely from rock1 contains1 of course1 no organic matter4,o ,still it is capable of bearing plants of a certain class1 and when these die1 they are deposited in the soil1 and thus form its organic portions1 rendering it capable of supporting those plants which furnish food for animals4 ,thousands of years must have been occupied in preparing the earth for habitation by man4 ,as the inorganic or mineral part of the soil is usually the largest1 we will consider it first4 ,as we have stated that this portion is formed from rocks1 we will examine their character1 with a view to showing the different qualities of soils4 ,what is the general rule concerning the composition of rocks8 ,do these distinctions affect the fertility of soils formed from them8 ,what do we mean by the mechanical character of the soil8 ,is its fertility indicated by its mechanical character8 ,as a general rule1 it may be stated that all rocks are either sandstones1 limestones1 or clays2 or a mixture of two or more of these ingredients4 ,hence we find that all mineral soils are either sandy1 calcareous1 7limey71 or clayey2 or consist of a mixture of these1 in which one or another usually predominates4 ,thus1 we speak of a sandy soil1 a clay soil1 etc4 ,these distinctions 7sandy1 clayey1 loamy1 etc47 are important in considering the mechanical character of the soil1 but have little reference to its fertility4 ,by mechanical character1 we mean those qualities which affect the ease of cultivation--excess or deficiency of water1 ability to withstand drought1 etc4 ,for instance1 a heavy clay soil is difficult to plow--retains water after rains1 and bakes quite hard during drought2 while a light sandy soil is plowed with ease1 often allows water to pass through immediately after rains1 and becomes dry and powdery during drought4 ,notwithstanding those differences in their mechanical character1 both soils may be very fertile1 or one more so than the other1 without reference to the clay and sand which they contain1 and which1 to our observation1 form their leading characteristics4 ,the same facts exist with regard to a loam1 a calcareous 7or limey7 soil1 or a vegetable mould4 ,their mechanical texture is not essentially an index to their fertility1 nor to the manures required to enable them to furnish food to plants4 ,it is true1 that each kind of soil appears to have some general quality of fertility or barrenness which is well known to practical men1 yet this is not founded on the fact that the clay or the sand1 or the vegetable matter1 enter more largely into the constitution of plants than they do when they are not present in so great quantities1 but on certain other facts which will be hereafter explained4 ,what is a sandy soil8 ,a clay soil8 ,a loamy soil8 ,a marl8 ,a calcareous soil8 ,a peaty soil8 ,as the following names are used to denote the character of soils1 in ordinary agricultural description1 we will briefly explain their application3 ,a ,sandy soil is1 of course1 one in which sand largely predominates4 ,clay soil1 one where clay forms a large proportion of the soil4 ,loamy soil1 where sand and clay are about equally mixed4 ,marl contains from five to twenty per cent4 of carbonate of lime4 ,calcareous soil more than twenty per cent4 ,peaty soils1 of course1 contain large quantities of organic matter4,p ,how large a part of the soil may be used as food by plants8 ,what do we learn from the analyses of barren and fertile soils8 ,we will now take under consideration that part of the soil on which depends its ability to supply food to the plant4 ,this portion rarely constitutes more than five or ten per cent4 of the entire soil1 sometimes less--and it has no reference to the sand1 clay1 and vegetable matters which they contain4 ,from analyses of many fertile soils1 and of others which are barren or of poorer quality1 it has been ascertained that the presence of certain ingredients is necessary to fertility4 ,this may be better explained by the assistance of the following table3 ---------------------------------------- ------------------------ ,in one hundred pounds4 ,soil fertile ,good ,barren4 without wheat soil4 manure4 ---------------------------------------- ------------------------ ,organic matter1 #i4g #g4j #d4j ,silica 7sand71 #fd4h #gd4c #gg4h ,alumina 7clay71 #e4g #e4e #i4a ,lime1 #e4i #a4d 4#d ,magnesia1 4#i

during the analysis #a4d #c4f 4#d ------------------------------------- #ajj4j #ajj4j #ajj4j ---------------------------------------- ------------------------ ,what can you say of the soils represented in the table of analyses8 ,what proportion of the fertilizing ingredients is required8 ,if the soil represented in the third column contained all the ingredients required except potash and soda1 would it be fertile8 ,what would be necessary to make it so8 ,what is the reason for this8 ,what are the offices performed by the inorganic part of soils8 ,the soil represented in the first column might still be fertile with less organic matter1 or with a larger proportion of clay 7alumina71 and less sand 7silica74 ,these affect its mechanical character2 but1 if we look down the column1 we notice that there are small quantities of lime1 magnesia1 and the other constituents of the ashes of plants 7except ox4 of manganese74 ,it is not necessary that they should be present in the soil in the exact quantity named above1 but not one must be entirely absent1 or greatly reduced in proportion4 ,by referring to the third column1 we see that these ingredients are not all present1 and the soil is barren4 ,even if it were supplied with all but one or two1 potash and soda for instance1 it could not support a crop without the assistance of manures containing these alkalies4 ,the reason for this must be readily seen1 as we have learned that no plant can arrive at maturity without the necessary supply of materials required in the formation of the ash1 and these materials can be obtained only from the soil2 consequently1 when they do not exist there1 it must be barren4 ,the inorganic part of soils has two distinct offices to perform4 ,the clay and sand form a mass of material into which roots can penetrate1 and thus plants are supported in their position4 ,these parts also absorb heat1 air and moisture to serve the purposes of growth1 as we shall see in a future chapter4 ,the minute portions of soil1 which comprise the acids1 alkalies1 and neutrals1 furnish plants with their ashes1 and are the most necessary to the fertility of the soil4 ,,geology4 ,what is geology8 ,is the same kind of rock always of the same composition8 ,how do rocks differ8 ,the relation between the inorganic part of soils and the rocks from which it was formed1 is the foundation of ,agricultural ,geology4 ,geology may be briefly named the science of rocks4 ,it would not be proper in an elementary work to introduce much of this study1 and we will therefore simply state that the same kind of rock is of the same composition all over the world2 consequently1 if we find a soil in ,new ,england formed from any particular rock1 and a soil from the same rock in ,asia1 their natural fertility will be the same in both localities4 ,some rocks consist of a mixture of different kinds of minerals2 and some1 consisting chiefly of one ingredient1 are of different degrees of hardness4 ,both of these changes must affect the character of the soil1 but it may be laid down as rule that1 when the rocks of two locations are exactly alike1 the soils formed from them will be of the same natural fertility1 and in proportion as the character of rocks changes1 in the same proportion will the soils differ4 ,what rule may be given in relation to soils formed from the same or different rocks8 ,are all soils formed from the rocks on which they lie8 ,what instances can you give of this8 ,in most districts the soil is formed from the rock on which it lies2 but this is not always the case4 ,soils are often formed by deposits of matter brought by water from other localities4 ,thus the alluvial banks of rivers consist of matters brought from the country through which the rivers have passed4 ,the river ,nile1 in ,egypt1 yearly overflows its banks1 and deposits large quantities of mud brought from the uninhabited upper countries4 ,the prairies of the ,west owe a portion of their soil to deposits by water4 ,swamps often receive the washings of adjacent hills2 and1 in these cases1 their soil is derived from a foreign source4 ,we might continue to enumerate instances of the relations between soils and the sources whence they originated1 thus demonstrating more fully the importance of geology to the farmer2 but it would be beyond the scope of this work1 and should be investigated by scholars more advanced than those who are studying merely the elements of agricultural science4 ,the mind1 in its early application to any branch of study1 should not be charged with intricate subjects4 ,it should master well the rudiments1 before investigating those matters which should follow such understanding4 ,in what light will plants and soils be regarded by those who understand them8 ,by pursuing the proper course1 it is easy to learn all that is necessary to form a good foundation for a thorough acquaintance with the subject4 ,if this foundation is laid thoroughly1 the learner will regard plants and soils as old acquaintances1 with whose formation and properties he is as familiar as with the construction of a building or simple machine4 ,a simple spear of grass will become an object of interest1 forming itself into a perfect plant1 with full development of roots1 stem1 leaves1 and seeds1 by processes with which he feels acquainted4 ,the soil will cease to be mere dirt2 it will be viewed as a compound substance1 whose composition is a matter of interest1 and whose care is productive of intellectual pleasure4 ,the commencement of study in any science must necessarily be wearisome to the young mind1 but its more advanced stages amply repay the trouble of early exertions4 ,,footnotes3 ,m ,the spaces between the particles4 ,n ,in very many instances the crevices and seams of rocks are permeated by roots1 which1 by decaying and thus inducing the growth of other roots1 cause these crevices to become filled with organic matter4 ,this1 by the absorption of moisture1 may expand with sufficient power to burst the rock4 ,o ,some rocks contain sulphur1 phosphorus1 etc41 and these may1 perhaps1 be considered as organic matter4 ,p ,these distinctions are not essential to be learned1 but are often convenient4 ,,chapter ,,ii4 ,,uses ,,of ,,organic ,,matter4 ,what proportion of organic matter is required for fertility8 ,how does the soil obtain its organic matter8 ,how does the growth of clover1 etc41 affect the soil8 ,it will be recollected that1 in addition to its mineral portions1 the soil contains organic matter in varied quantities4 ,it may be fertile with but one and a half per cent4 of organic matter1 and some peaty soils contain more than fifty per cent4 or more than one half of the whole4 ,the precise amount necessary cannot be fixed at any particular sum2 perhaps five parts in a hundred would be as good a quantity as could be recommended4 ,the soil obtains its organic matter in two ways4 ,first1 by the decay of roots and dead plants1 also of leaves1 which have been brought to it by wind1 etc4 ,second1 by the application of organic manures4 ,when organic matter decays in the soil1 what becomes of it8 ,is charcoal taken up by plants8 ,are humus and humic acid of great practical importance8 ,when a crop of clover is raised1 it obtains its carbon from the atmosphere2 and1 if it be plowed under1 and allowed to decay1 a portion of this carbon is deposited in the soil4 ,carbon constitutes nearly the whole of the dry weight of the clover1 aside from the constituents of water2 and1 when we calculate the immense quantity of hay1 and roots grown on an acre of soil in a single season1 we shall find that the amount of carbon thus deposited is immense4 ,if the clover had been removed1 and the roots only left to decay1 the amount of carbon deposited would still have been very great4 ,the same is true in all cases where the crop is removed1 and the roots remain to form the organic or vegetable part of the soil4 ,while undergoing decomposition1 a portion of this matter escapes in the form of gas1 and the remainder chiefly assumes the form of carbon 7or charcoal71 in which form it will always remain1 without loss1 unless driven out by fire4 ,if a bushel of charcoal be mixed with the soil now1 it will be the same bushel of charcoal1 neither more nor less1 a thousand years hence1 unless some influence is brought to bear on it aside from the growth of plants4 ,it is true that1 in the case of the decomposition of organic matter in the soil1 certain compounds are formed1 known under the general names of humus and humic acid1 which may1 in a slight degree1 affect the growth of plants1 but their practical importance is of too doubtful a character to justify us in considering them4 ,the application of manures1 containing organic matter1 such as peat1 muck1 animal manure1 etc41 supplies the soil with carbon on the same principle1 and the decomposing matters also generate,q carbonic acid gas while being decomposed4 ,the agricultural value of carbon in the soil depends 7as we have stated71 not on the fact that it enters into the composition of plants1 but on certain other important offices which it performs1 as follows3-- ,on what does the agricultural value of the carbon in the soil depend8 ,why does it make the soil more retentive of manure8 ,what is the experiment with the barrels of sand8 #a4 ,it makes the soil more retentive of manures4 #b4 ,it causes it to appropriate larger quantities of the fertilizing gases of the atmosphere4 #c4 ,it gives it greater power to absorb moisture4 #d4 ,it renders it warmer4 #a4 ,carbon 7or charcoal7 makes the soil retentive of manures1 because it has in itself a strong power to absorb1 and retain,r fertilizing matters4 ,there is a simple experiment by which this power can be shown4 ,ex4--,take two barrels of pure beach sand1 and mix with the sand in one barrel a few handfuls of charcoal dust1 leaving that in the other pure4 ,pour the brown liquor of the barn-yard through the pure sand1 and it will pass out at the bottom unaltered4 ,pour the same liquor through the barrel1 containing the charcoal1 and pure water will be obtained as a result4 ,the reason for this is that the charcoal retains all of the impurities of the liquor1 and allows only the water to pass through4 ,charcoal is often employed to purify water for drinking1 or for manufacturing purposes4 ,will charcoal purify water8 ,if a piece of tainted meat1 or a fishy duck be buried in a rich garden soil1 what takes place8 ,what is the reason of this8 ,how does charcoal overcome offensive odors8 ,how can you prove that charcoal absorbs the mineral impurities of water8 ,a rich garden-soil contains large quantities of carbonaceous matter2 and1 if we bury in such a soil a piece of tainted meat or a fishy duck1 it will1 in a short time1 be deprived of its odor1 because the charcoal in the soil will entirely absorb it4 ,carbon absorbs gases as well as the impurities of water2 and1 if a little charcoal be sprinkled over manure1 or any other substance1 emitting offensive odors1 the gases escaping will be taken up by the charcoal1 and the odor will cease4 ,it has also the power of absorbing mineral matters1 which are contained in water4 ,if a quantity of salt water be filtered through charcoal1 the salt will be retained1 and the water will pass through pure4 ,we are now able to see how carbon renders the soil retentive of manures4 #ast4 ,manures1 which resemble the brown liquor of barn-yards1 have their fertilizing matters taken out1 and retained by it4 ,how does charcoal in the soil affect the manures applied8 ,why does charcoal in the soil cause it to appropriate the gases of the atmosphere8 ,what fertilizing gases exist in the atmosphere8 ,how are they carried to the soil8 ,does the carbon retain them after they reach the soil8 ,what can you say of the air circulating through the soil8 ,how does carbon give the soil power to absorb moisture8 #b;d4 ,the gases arising from the decomposition 7rotting7 of manure are absorbed by it4 #c;d4 ,the soluble mineral portions of manure1 which might in some soils leach down with water1 are arrested and retained at a point at which they can be made use of by the roots of plants4 #b4 ,charcoal in the soil causes it to appropriate larger quantities of the fertilizing gases of the atmosphere1 on account of its power1 as just named1 to absorb gases4 ,the atmosphere contains results1 which have been produced by the breathing of animals and by the decomposition of various kinds of organic matter1 which are exposed to atmospheric influences4 ,these gases are chiefly ammonia and carbonic acid1 both of which are largely absorbed by water1 and consequently are contained in rain1 snow1 etc41 which1 as they enter the soil1 give up these gases to the charcoal1 and they there remain until required by plants4 ,even the air itself1 in circulating through the soil1 gives up fertilizing gases to the carbon1 which it may contain4 #c4 ,charcoal gives to the soil power to absorb moisture1 because it is itself one of the best absorbents in nature2 and it has been proved by accurate experiment that peaty soils absorb moisture with greater rapidity1 and part with it more slowly than any other kind4 ,how does it render it warmer8 ,is the heat produced by the decomposition of organic matter perceptible to our senses8 ,is it so to the growing plant8 ,what is another important part of the organic matter in the soil8 #d4 ,carbon in the soil renders it warmer1 because it darkens its color4 ,black surfaces absorb more heat than light ones1 and a black coat1 when worn in the sun1 is warmer than one of a lighter color4 ,by mixing carbon with the soil1 we darken its color1 and render it capable of absorbing a greater amount of heat from the sun's rays4 ,it will be recollected that1 when vegetable matter decomposes in the soil1 it produces certain gases 7carbonic acid1 etc471 which either escape into the atmosphere1 or are retained in the soil for the use of plants4 ,the production of these gases is always accompanied by heat1 which1 though scarcely perceptible to our senses1 is perfectly so to the growing plant1 and is of much practical importance4 ,this will be examined more fully in speaking of manures4 ,how is it obtained by the soil8 ,what offices does the organic matter in the soil perform8 ,another important part of the organic matter in the soil is that which contains nitrogen4 ,this forms but a very small portion of the soil1 but it is of the greatest importance to vegetables4 ,as the nitrogen in food is of absolute necessity to the growth of animals1 so the nitrogen in the soil is indispensable to the growth of cultivated plants4 ,it is obtained by the soil in the form of ammonia 7or nitric acid71 from the atmosphere1 or by the application of animal matter4 ,in some cases1 manures called nitrates,s are used2 and1 in this manner1 nitrogen is given to the soil4 ,we have now learned that the organic matter in the soil performs the following offices3-- ,organic matter thoroughly decomposed is carbon1 and has the various effects ascribed to this substance on p4 #gi4 ,organic matter in process of decay produces carbonic acid1 and sometimes ammonia in the soil2 also its decay causes heat4 ,organic matter containing nitrogen1 such as animal substances1 etc41 furnish ammonia1 and other nitrogenous substances to the roots of plants4 ,,footnotes3 ,q ,produce4 ,r ,by absorbing and retaining1 we mean taking up and holding4 ,s ,nitrates are compounds of nitric acid 7which consists of nitrogen and oxygen71 and alkaline substances4 ,thus nitrate of potash 7saltpetre71 is composed of nitric acid and potash3 nitrate of soda 7cubical nitre71 of nitric acid and soda4 ,,chapter ,,iii4 ,,uses ,,of ,,inorganic ,,matter4 ,what effect has clay besides the one already named8 ,how does it compare with charcoal for this purpose8 ,the offices performed by the inorganic constituents of the soil are many and important4 ,these1 as well as the different conditions in which the bodies exist1 are necessary to be thoroughly studied4 ,those parts which constitute the larger proportion of the soil1 namely the clay1 sand1 and limy portions1 are useful for purposes which have been named in the first part of this section1 while the clay has an additional effect in the absorption of ammonia4 ,for this purpose1 it is as effectual as charcoal1 the gases escaping from manures1 as well as those existing in the atmosphere1 and in rain-water1 being arrested by clay as well as charcoal4,t ,what particular condition of inorganic matter is requisite for fertility8 ,what is the fixed rule with regard to this8 ,what is the condition of the alkalies in most of their combinations8 ,of the acids8 ,what is said of phosphate of lime8 ,the more minute ingredients of the soil--those which enter into the construction of plants--exist in conditions which are more or less favorable or injurious to vegetable growth4 ,the principal condition necessary to fertility is capacity to be dissolved1 it being 7so far as we have been able to ascertain7 a fixed rule1 as was stated in the first section1 that no mineral substance can enter into the roots of a plant except it be dissolved in water4 ,the alkalies potash1 soda1 lime1 and magnesia1 are in nearly all of their combinations in the soil sufficiently soluble for the purposes of growth4 ,the acids are1 as will be recollected1 sulphuric and phosphoric4 ,these exist in the soil in combination with the alkalies1 as sulphates and phosphates1 which are more or less soluble under natural circumstances4 ,phosphoric acid in combination with lime as phosphate of lime is but slightly soluble2 but1 when it exists in the compound known as super-phosphate of lime1 it is much more soluble1 and consequently enters into the composition of plants with much greater facility4 ,this matter will be more fully explained in the section on manures4 ,how may silica be rendered soluble8 ,what is the condition of chlorine in the soil8 ,do peroxide and protoxide of iron affect plants in the same way8 ,how would you treat a soil containing protoxide of iron8 ,on what does the usefulness of all these matters in the soil depend8 ,the neutrals1 silica1 chlorine1 oxide of iron1 and oxide of manganese1 deserve a careful examination4 ,silica exists in the soil usually in the form of sand1 in which it is1 as is well known1 perfectly insoluble2 and1 before it can be used by plants1 which often require it in large quantities1 it must be made soluble1 which is done by combining it with an alkali4 ,for instance1 if the silica in the soil is insoluble1 we must make an application of an alkali1 such as potash1 which will unite with the silica1 and form the silicate of potash1 which is in the exact condition to be dissolved and carried into the roots of plants4 ,chlorine in the soil is probably always in an available condition4 ,oxide of iron exists1 as has been previously stated1 usually in the form of the peroxide 7or red oxide74 ,sometimes1 however1 it exists in the form of the protoxide 7or black oxide71 which is poisonous to plants1 and renders the soil unfertile4 ,by loosening the soil in such a manner as to admit air and water1 this compound takes up more oxygen1 which renders it a peroxide1 and makes it available for plants4 ,the oxide of manganese is probably of little consequence4 ,the usefulness of all of these matters in the soil depends on their exposure2 if they are in the interior of particles1 they cannot be made use of2 while1 if the particles are so pulverized that their constituents are exposed1 they become available1 because water can immediately attack to dissolve1 and carry them into roots4 ,what is one of the chief offices of plowing and hoeing8 ,is the subsoil usually different from the surface soil8 ,what circumstances have occasioned the difference8 ,in what way8 ,this is one of the great offices of plowing and hoeing2 the lumps of soil being thereby more broken up and exposed to the action of atmospheric influences1 which are often necessary to produce a fertile condition of soil1 while the trituration of particles reduces them in size4 ,,subsoil4 ,may the subsoil be made to resemble the surface soil8 ,may all soils be brought to the highest state of fertility8 ,on what examination must improvement be based8 ,what is the difference between the soil of some parts of ,massachusetts and that of the ,miami valley8 ,the subsoil is usually of a different character from the surface soil1 but this difference is more often the result of circumstances than of formation4 ,the surface soil from having been long cultivated has been more opened to the influences of the air than is the case with the subsoil1 which has never been disturbed so as to allow the same action4 ,again the growth of plants has supplied the surface soil with roots1 which by decaying have given it organic matter1 thus darkening its color1 rendering it warmer1 and giving greater ability to absorb heat and moisture1 and to retain manures4 ,all of these effects render the surface soil of a more fertile character than it was before vegetable growth commenced2 and1 where frequent cultivation and manures have been applied1 a still greater benefit has resulted4 ,in most instances the subsoil may by the same means be gradually improved in condition until it equals the surface soil in fertility4 ,the means of producing this result1 also farther accounts of its advantages1 will be given under the head of ,cultivation 7,sect4 ,,iv47 ,,improvement4 ,from what has now been said of the character of the soil1 it must be evident that1 as we know the causes of fertility and barrenness1 we may by the proper means improve the character of all soils which are not now in the highest state of fertility4 ,chemical analysis will tell us the composition of a soil1 and an examination1 such as any farmer may make1 will inform us of its deficiencies in mechanical character1 and we may at once resort to the proper means to secure fertility4 ,in some instances the soil may contain every thing that is required1 but not in the necessary condition4 ,for instance1 in some parts of ,massachusetts1 there are nearly barren soils which show by analysis precisely the same chemical composition as the soil of the ,miami valley of ,ohio1 one of the most fertile in the world4 ,the cause of this great difference in their agricultural capabilities1 is that the ,miami soil has its particles finely pulverized2 while in the ,massachusetts soil the ingredients are combined within particles 7such as pebbles1 etc471 where they are out of the reach of roots4 ,why do soils of the same degree of fineness sometimes differ in fertility8 ,can soils always be rendered fertile with profit8 ,can we determine the cost before commencing the work8 ,what must be done before a soil can be cultivated understandingly8 ,what must be done to keep up the quality of the soil8 ,in other cases1 we find two soils1 which are equally well pulverized1 and which appear to be of the same character1 having very different power to support crops4 ,chemical analysis will show in these instances a difference of composition4 ,all of these differences may be overcome by the use of the proper means4 ,sometimes it could be done at an expense which would be justified by the result2 and1 at others1 it might require too large an outlay to be profitable4 ,it becomes a question of economy1 not of ability1 and science is able to estimate the cost4 ,soil cannot be cultivated understandingly until it has been subjected to such an examination as will tell us exactly what is necessary to render it fertile4 ,even after fertility is perfectly restored it requires thought and care to maintain it4 ,the ingredients of the soil must be returned in the form of manures as largely as they are removed by the crop1 or the supply will eventually become too small for the purposes of vegetation4 ,,footnotes3 ,t ,it is due to our country1 as well as to ,prof4 ,mapes and others1 who long ago explained this absorptive power of clay and carbon1 to say that the subject was perfectly understood and practically applied in ,america a number of years before ,prof4 ,way published the discovery in ,england as original4 ,,section ,,third4 ,,manures4 ,,chapter ,i4 ,,character ,,and ,,varieties ,,of ,,manures4 ,what must a farmer know in order to avoid failures8 ,can this be learned entirely from observation8 ,what kind of action have manures8 ,give examples of each of these4 ,may mechanical effects be produced by chemical action8 ,how does potash affect the soil8 ,to understand the science of manures is the most important branch of practical farming4 ,no baker would be called a good practical baker who kept his flour exposed to the sun and rain4 ,no shoemaker would be called a good practical shoemaker1 who used morocco for the soles of his shoes1 and heavy leather for the uppers4 ,no carpenter would be called a good practical carpenter1 who tried to build a house without nails1 or other fastenings4 ,so with the farmer4 ,he cannot be called a good practical farmer if he keeps the materials1 from which he is to make plants1 in such a condition1 that they will have their value destroyed1 uses them in the wrong places1 or tries to put them together without having every thing present that is necessary4 ,before he can avoid failures with certainty1 he must know what manures are composed of1 how they are to be preserved1 where they are needed1 and what kinds are required4 ,true1 he may from observation and experience1 guess at results1 but he cannot know that he is right until he has learned the facts above named4 ,in this section of our work1 we mean to convey some of the information necessary to this branch of practical farming4 ,we shall adopt a classification of the subject somewhat different from that found in most works on manures1 but the facts are the same4 ,the action of manures is either mechanical or chemical1 or a combination of both4 ,for instance3 some kinds of manure improve the mechanical character of the soil1 such as those which loosen stiff clay soils1 or others which render light sandy soils compact--these are called mechanical manures4 ,some again furnish food for plants--these are called chemical manures4 ,many mechanical manures produce their effects by means of chemical action4 ,thus potash combines chemically with sand in the soil4 ,in so doing1 it roughens the surfaces of the particles of sand1 and renders the soil less liable to be compacted by rains4 ,in this manner1 it acts as a mechanical manure4 ,the compound of sand and potash1,u as well as the potash alone1 may enter into the composition of plants1 and hence it is a chemical manure4 ,in other words1 potash belongs to both classes described above4 ,it is important that this distinction should be well understood by the learner1 as the words mechanical and chemical in connection with manures will be made use of throughout the following pages4 ,what are absorbents8 ,what kind of manure is charcoal8 ,there is another class of manures which we shall call absorbents4 ,these comprise those substances which have the power of taking up fertilizing matters1 and retaining them for the use of plants4 ,for instance1 charcoal is an absorbent4 ,as was stated in the section on soils1 this substance is a retainer of all fertilizing gases and many minerals4 ,other matters made use of in agriculture have the same effect4 ,these absorbents will be spoken of more fully in their proper places4 ,,table4 ,,mechanical ,,manures are those which improve the mechanical condition of soils4 ,,chemical are those which serve as food for plants4 ,,absorbents are those substances which absorb and retain fertilizing matters4 ,into what classes may manures be divided8 ,what are organic manures8 ,inorganic8 ,atmospheric8 ,manures may be divided into three classes1 viz43 organic1 inorganic1 and atmospheric4 ,,organic manures comprise all animal and vegetable matters which are used to fertilize the soil1 such as dung1 muck1 etc4 ,,inorganic manures are those which are of a purely mineral character1 such as lime1 ashes1 etc4 ,,atmospheric manures consist of those organic manures which are in the form of gases in the atmosphere1 and which are absorbed by rains and carried to the soil4 ,these are of immense importance4 ,the ammonia and carbonic acid in the air are atmospheric manures4 ,,footnotes3 ,u ,silicate of potash4 ,,chapter ,,ii4 ,,excrements ,,of ,,animals4 ,of what is animal excrement composed8 ,explain the composition of the food of animals4 ,what does hay contain8 ,to what does ,liebig compare the consumption of food by animals1 and why8 ,the first organic manure which we shall examine1 is animal excrement4 ,this is composed of those matters which have been eaten by the animal as food1 and have been thrown off as solid or liquid manure4 ,in order that we may know of what they consist1 we must refer to the composition of food and examine the process of digestion4 ,the food of animals1 we have seen to consist of both organic and inorganic matter4 ,the organic part may be divided into two classes1 i4 e41 that portion which contains nitrogen--such as gluten1 albumen1 etc41 and that which does not contain nitrogen--such as starch1 sugar1 oil1 etc4 ,the inorganic part of food may also be divided into soluble matter and insoluble matter4 ,,digestion ,,and ,,its ,,products4 ,of what does that part of dung consist which resembles soot8 ,what else does the dung contain8 ,in what manner does the digested part of food escape from the body8 ,let us now suppose that we have a full-grown ox1 which is not increasing in any of his parts1 but only consumes food to keep up his respiration1 and to supply the natural wastes of his body4 ,to this ox we will feed a ton of hay which contains organic matter1 with and without nitrogen1 and soluble and insoluble inorganic substances4 ,now let us try to follow it through its changes in the animal1 and observe its destination4 ,liebig compares the consumption of food by animals to the imperfect burning of wood in a stove1 where a portion of the fuel is resolved into gases and ashes 7that is1 it is completely burned71 and another portion1 which is not thoroughly burned1 passes off as soot4 ,in the animal action in question1 the food undergoes changes which are similar to this burning of wood4 ,a part of the food is digested and taken up by the blood1 while another portion remains undigested1 and passes the bowels as solid dung--corresponding to soot4 ,this part of the dung then1 we see is merely so much of the food as passes through the system without being materially changed4 ,its nature is easily understood4 ,it contains organic and inorganic matter in nearly the same condition as they existed in the hay4 ,they have been rendered finer and softer1 but their chemical character is not materially altered4 ,the dung also contains small quantities of nitrogenous matter1 which leaked out1 as it were1 from the stomach and intestines4 ,the digested food1 however1 undergoes further changes which affect its character1 and it escapes from the body in three ways--i4 e41 through the lungs1 through the bladder1 and through the bowels4 ,it will be recollected from the first section of this book1 p4 #bb1 that the carbon in the blood of animals1 unites with the oxygen of the air drawn into the lungs1 and is thrown off in the breath as carbonic acid4 ,the hydrogen and oxygen unite to form a part of the water which constitutes the moisture of the breath4 ,explain the escape of carbon1 hydrogen and oxygen4 ,what becomes of the nitrogenous parts8 ,how is the soluble ash of the digested food parted with8 ,the insoluble8 ,if any portions of the food are not returned in the dung1 how are they disposed of8 ,that portion of the organic part of the hay which has been taken up by the blood of the ox1 and which does not contain nitrogen 7corresponding to the first class of proximates1 as described in ,sect4 ,i71 is emitted through the lungs4 ,it consists1 as will be recollected1 of carbon1 hydrogen and oxygen1 and these assume1 in respiration1 the form of carbonic acid and water4 ,the organic matter of the digested hay1 in the blood1 which contains nitrogen 7corresponding to the second class of proximates1 described in ,sect4 ,i71 goes to the bladder1 where it assumes the form of urea--a constituent of urine or liquid manure4 ,we have now disposed of the imperfectly digested food 7dung71 and of the organic matter which was taken up by the blood4 ,all that remains to be examined is the inorganic or mineral matter in the blood1 which would have become ashes1 if the hay had been burned4 ,the soluble part of this inorganic matter passes into the bladder1 and forms the inorganic part of urine4 ,the insoluble part passes the bowels1 in connection with the dung4 ,how is their place supplied8 ,is food put out of existence when it is fed to animals8 ,what does the solid dung contain8 ,liquid manure8 ,the breath8 ,if any of the food taken up by the blood is not returned as above stated1 it goes to form fat1 muscle1 hair1 bones1 or some other part of the animal1 and as he is not growing 7not increasing in weight7 an equivalent amount of the body of the animal goes to the manure to take the place of the part retained4,v ,we now have our subject in a form to be readily understood4 ,we learn that when food is given to animals it is not put out of existence1 but is merely changed in form2 and that in the impurities of the breath1 we have a large portion of those parts of the food which plants obtain from air and from water2 while the solid and liquid excrements contain all that was taken by the plants from the soil and manures4 ,the ,,solid ,,dung contains the undigested parts of the food1 the insoluble parts of the ash1 and the nitrogenous matters which have escaped from the digestive organs4 ,,liquid ,,manure the nitrogenous or second class of proximates of the digested food1 and the soluble parts of the ash4 ,,the ,,breath contains the first class of proximates1 those which contain carbon1 hydrogen and oxygen1 but no nitrogen4,w ,,footnotes3 ,v ,this account of digestion is not1 perhaps1 strictly accurate in a physiological point of view1 but it is sufficiently so to give an elementary understanding of the character of excrements as manures4 ,w ,the excrements of animals contain more or less of sulphur1 and sometimes small quantities of phosphorus4 ,,chapter ,,iii4 ,,waste ,,of ,,manure4 ,what are the first causes of loss of manure8 ,what is evaporation8 ,the loss of manure is a subject which demands most serious attention4 ,until within a few years1 little was known about the true character of manures1 and consequently1 of the importance of protecting them against loss4 ,the first causes of waste are evaporation and leaching4 ,,evaporation4 ,name a solid body which evaporates4 ,what takes place when a dead animal is exposed to the atmosphere for a sufficient time8 ,what often assist the evaporation of solids8 ,evaporation is the changing of a solid or liquid body to a vapory form4 ,thus common smelling salts1 a solid1 if left exposed1 passes into the atmosphere in the form of a gas or vapor4 ,water1 a liquid1 evaporates1 and becomes a vapor in the atmosphere4 ,this is the case with very many substances1 and in organic nature1 both solid and liquid1 they are liable to assume a gaseous form1 and become mixed with the atmosphere4 ,they are not destroyed1 but are merely changed in form4 ,as an instance of this action1 suppose an animal to die and to decay on the surface of the earth4 ,after a time1 the flesh will entirely disappear1 but is not lost4 ,it no longer exists as the flesh of an animal1 but its carbon1 hydrogen1 oxygen1 and nitrogen1 still exist in the air4 ,they have been liberated from the attractions which held them together1 and have passed away2 but 7as we already know from what has been said in a former section7 they are ready to be again taken up by plants1 and pressed into the service of life4 ,the evaporation of liquids may take place without the aid of any thing but heat2 still1 in the case of solids1 it is often assisted by decay and combustion1 which break up the bonds that hold the constituents of bodies together1 and thus enable them to return to the atmosphere1 from which they were originally derived4 ,what is the cause of odor8 ,when we perceive an odor1 what is taking place8 ,why do manures give off offensive odors8 ,how may we detect ammonia escaping from manure8 ,it must be recollected that every thing1 which has an odor 7or can be smelled71 is evaporating4 ,the odor is caused by parts of the body floating in the air1 and acting on the nerves of the nose4 ,this is an invariable rule2 and1 when we perceive an odor1 we may be sure that parts of the material1 from which it emanates1 are escaping4 ,if we perceive the odor of an apple1 it is because parts of the volatile oils of the apple enter the nose4 ,the same is true when we smell hartshorn1 cologne1 etc4 ,manures made by animals have an offensive odor1 simply because volatile parts of the manure escape into the air1 and are therefore made perceptible4 ,all organic parts in turn become volatile1 assuming a gaseous form as they decompose4 ,we do not see the gases rising1 but there are many ways by which we can detect them4 ,if we wave a feather over a manure heap1 from which ammonia is escaping1 the feather having been recently dipped in manure1 white fumes will appear around the feather1 being the muriate of ammonia formed by the union of the escaping gas with the muriatic acid4 ,not only ammonia1 but also carbonic acid1 and other gases which are useful to vegetation escape1 and are given to the winds4 ,indeed it may be stated in few words that all of the organic part of plants 7all that was obtained from the air1 water1 and ammonia71 constituting more than nine tenths of their dry weight1 may be evaporated by the assistance of decay or combustion4 ,the organic part of manures may be lost in the same manner2 and1 if the process of decomposition be continued long enough1 nothing but a mass of mineral matter will remain1 except perhaps a small quantity of carbon which has not been resolved into carbonic acid4 ,what remains after manure has been long exposed to decomposition8 ,what gaseous compounds are formed by the decomposition of manures8 ,the proportion of solid manure lost by evaporation 7made by the assistance of decay71 is a very large part of the whole4 ,manure cannot be kept a single day in its natural state without losing something4 ,it commences to give out an offensive odor immediately1 and this odor is occasioned1 as was before stated1 by the loss of some of its fertilizing parts4 ,animal manure contains1 as will be seen by reference to p4 #ajj1 all of the substances contained in plants1 though not always in the correct relative proportions to each other4 ,when decomposition commences1 the carbon unites with the oxygen of the air1 and passes off as carbonic acid2 the hydrogen and oxygen combine to form water 7which evaporates71 and the nitrogen is mostly resolved into ammonia1 which escapes into the atmosphere4 ,describe fire-fanging4 ,what takes place when animal manure is exposed in an open barn-yard8 ,what does liquid manure lose by evaporation8 ,if manure is thrown into heaps1 it often ferments so rapidly as to produce sufficient heat to set fire to some parts of the manure1 and cause it to be thrown off with greater rapidity4 ,this may be observed in nearly all heaps of animal excrement4 ,when they have lain for some time in mild weather1 gray streaks of ashes are often to be seen in the centre of the pile4 ,the organic part of the manure having been burned away1 nothing but the ash remains1--this is called fire-fanging4 ,manures kept in cellars without being mixed with refuse matter are subject to the same losses4 ,when kept in the yard1 they are still liable to be lost by evaporation4 ,they are here often saturated with water1 and this water in its evaporation carries away the ammonia1 and carbonic acid which it has obtained from the rotting mass4 ,the evaporation of the water is rapidly carried on1 on account of the great extent of surface4 ,the whole mass is spongy1 and soaks the liquids up from below 7through hollow straws1 etc471 to be evaporated at the surface on the same principle as causes the wick of a lamp to draw up the oil to supply fuel for the flame4 ,,liquid ,,manure containing large quantities of nitrogen1 and forming much ammonia1 is also liable to lose all of its organic part from evaporation 7and fermentation71 so that it is rendered as much less valuable as is the solid dung4,x ,when does the waste of exposed manure commence8 ,what does economy of manure require8 ,what is the effect of leaching8 ,give an illustration of leaching4 ,from these remarks1 it may be justly inferred that a very large portion of the value of solid and liquid manure as ordinarily kept is lost by evaporation in a sufficient length of time1 depending on circumstances1 whether it be three months or several years4 ,the wasting commences as soon as the manure is dropped1 and continues1 except in very cold weather1 until the destruction is complete4 ,hence we see that true economy requires that the manures of the stable1 stye1 and poultry-house1 should be protected from evaporation 7as will be hereafter described71 as soon as possible after they are made4 ,,leaching4 ,the subject of leaching is as important in considering the inorganic parts of manures as evaporation is to the organic1 while leaching also affects the organic gases1 they being absorbed by water in a great degree4 ,a good illustration of leaching is found in the manufacture of potash4 ,when water is poured over wood-ashes1 it dissolves their potash which it carries through in solution1 making ley4 ,if ley is boiled to dryness1 it leaves the potash in a solid form1 proving that this substance had been dissolved by the water and removed from the insoluble parts of the ashes4 ,how does water affect decomposing manures8 ,does continued decomposition continue to prepare material to be leached away8 ,how far from the surface of the soil may organic constituents be carried by water8 ,in the same way water in passing through manures takes up the soluble portions of the ash as fast as liberated by decomposition1 and carries them into the soil below2 or1 if the water runs off from the surface1 they accompany it4 ,in either case they are lost to the manure4 ,there is but a small quantity of ash exposed for leaching in recent manures2 but1 as the decomposition of the organic part proceeds1 it continues to develope it more and more 7in the same manner as burning would do1 only slower71 thus preparing fresh supplies to be carried off with each shower4 ,in this way1 while manures are largely injured by evaporation1 the soluble inorganic parts are removed by water until but a small remnant of its original fertilizing properties remains4 ,what arrests their farther progress8 ,what would be the effect of allowing these matters to filter downwards8 ,what does evaporation remove from manure8 ,leaching8 ,it is a singular fact concerning leaching1 that water is able to carry no part of the organic constituents of vegetables more than about thirty-four inches below the surface in a fertile soil4 ,they would probably be carried to an unlimited distance in pure sand1 as it contains nothing which is capable of arresting them2 but1 in most soils1 the clay and carbon which they contain retain all of the ammonia2 also nearly all of the matters which go to form the inorganic constituents of plants within about the above named distance from the surface of the soil4 ,if such were not the case1 the fertility of the earth must soon be destroyed1 as all of those elements which the soil must supply to growing plants would be carried down out of the reach of roots1 and leave the world a barren waste1 its surface having lost its elements of fertility1 while the downward filtration of these would render the water of wells unfit for our use4 ,now1 however1 they are all retained near the surface of the soil1 and the water issues from springs comparatively pure4 ,,evaporation removes from manure-- ,carbon1 in the form of carbonic acid4 ,hydrogen and oxygen1 in the form of water4 ,nitrogen1 in the form of ammonia4 ,,leaching removes from manure-- ,the soluble and most valuable parts of the ash in solution in water1 besides carrying away some of the named above forms of organic matter4 ,,footnotes3 ,x ,it should be recollected that every bent straw may act as a syphon1 and occasion much loss of liquid manure4 ,,chapter ,,iv4 ,,absorbents4 ,what substances are called absorbents8 ,what is the most important of these8 ,what substances are called charcoal in agriculture8 ,how is vegetable matter rendered useful as charcoal8 ,before considering farther the subject of animal excrement1 it is necessary to examine a class of manures known as absorbents4 ,these comprise all matters which have the power of absorbing1 or soaking up1 as it were1 the gases which arise from the evaporation of solid and liquid manures1 and retaining them until required by plants4 ,the most important of these is undoubtedly carbon or charcoal4 ,,charcoal4 ,charcoal1 in an agricultural sense1 means all forms of carbon1 whether as peat1 muck1 charcoal dust from the spark-catchers of locomotives1 charcoal hearths1 river and swamp deposits1 leaf mould1 decomposed spent tanbark or sawdust1 etc4 ,in short1 if any vegetable matter is decomposed with the partial exclusion of air 7so that there shall not be oxygen enough supplied to unite with all of the carbon71 a portion of its carbon remains in the exact condition to serve the purposes of charcoal4 ,what is the first-named effect of charcoal8 ,the second8 ,third8 ,fourth8 ,explain the first action4 ,the offices performed in the soil by carbonaceous matter were fully explained in a former section 7p4 #gi1 ,sect4 #b71 and we will now examine merely its action with regard to manures4 ,when properly applied to manures1 in compost1 it has the following effects3 #a4 ,it absorbs and retains the fertilizing gases evaporating from decomposing matters4 #b4 ,it acts as a divisor1 thereby reducing the strength 7or intensity7 of powerful manures--thus rendering them less likely to injure the roots of plants2 and also increases their bulk1 so as to prevent fire fanging in composts4 #c4 ,it in part prevents the leaching out of the soluble parts of the ash4 #d4 ,it keeps the compost moist4 ,the first-named office of charcoal1 i4 e41 absorbing and retaining gases1 is one of the utmost importance4 ,it is this quality that gives to it so high a position in the opinion of all who have used it4 ,as was stated in the section on soils1 carbonaceous matter seems to be capable of absorbing every thing which may be of use to vegetation4 ,it is a grand purifier1 and while it prevents offensive odors from escaping1 it is at the same time storing its pores with food for the nourishment of plants4 ,explain its action as a divisor4 ,how does charcoal protect composts against injurious action of rains8 ,how does it keep them moist8 #b;d4 ,in its capacity as a divisor for manures1 charcoal should be considered as excellent in all cases1 especially to use with strongly concentrated 7or heating7 animal manures4 ,these1 when applied in their natural state to the soil1 are very apt to injure young roots by the violence of their action4 ,when mixed with a divisor1 such manures are diluted1 made less active1 and consequently less injurious4 ,in composts1 manures are liable1 as has been before stated1 to become burned by the resultant heat of decomposition2 this is called fire fanging1 and is prevented by the liberal use of divisors1 because1 by increasing the bulk1 the heat being diffused through a larger mass1 becomes less intense4 ,the same principle is exhibited in the fact that it takes more fire to boil a cauldron of water than a tea-kettle full4 #c;d4 ,charcoal has much power to arrest the passage of mineral matters in solution2 so much so1 that compost heaps1 well supplied with muck1 are less affected by rains than those not so supplied4 ,all composts1 however1 should be kept under cover4 #dth4 ,charcoal keeps the compost moist from the ease with which it absorbs water1 and its ability to withstand drought4 ,what source of carbon is within the reach of most farmers8 ,what do we mean by muck8 ,of what does it consist8 ,how does it differ in quality8 ,with these advantages before us1 we must see the importance of an understanding of the modes for obtaining charcoal4 ,many farmers are so situated that they can obtain sufficient quantities of charcoal dust4 ,others have not equal facilities4 ,nearly all1 however1 can obtain muck1 and to this we will now turn our attention4 ,,muck1 ,,and ,,the ,,lime ,,and ,,salt ,,mixture4 ,what is the first step in preparing muck for decomposition8 ,with what proportion of the lime and salt mixture should it be composted8 ,why should this compost be made under cover8 ,what is this called after decomposition8 ,why should we not use muck immediately after taking it from the swamp8 ,by muck1 we mean the vegetable deposits of swamps and rivers4 ,it consists of decayed organic substances1 mixed with more or less earth4 ,its principal constituent is carbon1 in different degrees of development1 which has remained after the decomposition of vegetable matter4 ,muck varies largely in its quality1 according to the amount of carbon which it contains1 and the perfection of its decomposition4 ,the best muck is usually found in comparatively dry locations1 where the water which once caused the deposit has been removed4 ,muck which has been long in this condition1 is usually better decomposed than that which is saturated with water4 ,the muck from swamps1 however1 may soon be brought to the best condition4 ,it should be thrown out1 if possible1 at least one year before it is required for use 7a less time may suffice1 except in very cold climates7 and left1 in small heaps or ridges1 to the action of the weather1 which will assist in pulverizing it1 while1 from having its water removed1 its decomposition goes on more rapidly4 ,after the muck has remained in this condition a sufficient length of time1 it may be removed to the barn-yard and composted with the lime and salt mixture 7described on page #aae7 in the proportion of one cord of muck to four bushels of the mixture4 ,this compost ought to be made under cover1 lest the rain leach out the constituents of the mixture1 and thus occasion loss2 at the end of a month or more1 the muck in the compost will have been reduced to a fine pulverulent mass1 nearly equal to charcoal dust for application to animal excrement4 ,when in this condition it is called prepared muck1 by which name it will be designated in the following pages4 ,muck should not be used immediately after being taken from the swamp1 as it is then almost always sour1 and is liable to produce sorrel4 ,its sourness is due to acids which it contains1 and these must be rectified by the application of an alkali1 or by long exposure to the weather1 before the muck is suitable for use4 ,,lime ,,and ,,salt ,,mixture4 ,what proportions of lime and salt are required for the decomposing mixture8 ,explain the process of making it4 ,why should it be made under cover8 ,the lime and salt mixture1 used in the decomposition of muck1 is made in the following manner3 ,,recipe4--,take three bushels of shell lime1 hot from the kiln1 or as fresh as possible1 and slake it with water in which one bushel of salt has been dissolved4 ,care must be taken to use only so much water as is necessary to dissolve the salt1 as it is difficult to induce the lime to absorb a larger quantity4 ,in dissolving the salt1 it is well to hang it in a basket in the upper part of the water1 as the salt water will immediately settle towards the bottom 7being heavier71 and allow the freshest water to be nearest to the salt4 ,in this way1 the salt may be all dissolved1 and thus make the brine used to slake the lime4 ,it may be necessary to apply the brine at intervals of a day or two1 and to stir the mass often1 as the amount of water is too great to be readily absorbed4 ,this mixture should be made under cover1 as1 if exposed1 it would obtain moisture from rain or dew1 which would prevent the use of all the brine4 ,another objection to its exposure to the weather is its great liability to be washed away by rains4 ,it should be at least ten days old before being used1 and would probably be improved by an age of three or four months1 as the chemical changes it undergoes will require some time to be completed4 ,explain the character of this mixture as represented in the diagram4 7,black board47 ,the character of this mixture may be best described by the following diagram3-- ,we have originally-- ---------------------------------- ,lime- ,salt consisting of ---,chlorine ,chloride and of -,sodium4 ,sodium4 --,carbonic acid and --,oxygen in the air4 -,chloride of lime4- -,carbonate of ,soda4 ,y ,the lime unites with the chlorine of the salt and forms chloride of lime4 ,the sodium1 after being freed from the chlorine1 unites with the oxygen of the air and forms soda1 which1 combining with the carbonic acid of the atmosphere1 forms carbonate of soda4 ,chloride of lime and carbonate of soda are better agents in the decomposition of muck than pure salt and lime2 and1 as these compounds are the result of the mixture1 much benefit ensues from the operation4 ,when shell lime cannot be obtained1 ,thomaston1 or any other very pure lime1 will answer1 though care must be taken that it do not contain much magnesia4 ,,lime4 ,what effect has lime on muck8 ,on what does the energy of this effect depend8 ,why should a compost of muck and lime be protected from rain8 ,muck may be decomposed by the aid of other materials4 ,lime is very efficient1 though not as much so as when combined with salt4 ,the action of lime1 when applied to the muck1 depends very much on its condition4 ,air-slaked lime 7carbonate of lime71 and hydrate of lime1 slaked with water1 have but a limited effect compared with lime freshly burned and applied in a caustic 7or pure7 form4 ,when so used1 however1 the compost should not be exposed to rains1 as this would have a tendency to make mortar which would harden it4 ,,potash4 ,is potash valuable for this use8 ,from what sources may potash be obtained8 ,in what proportion should ashes be applied to muck8 ,sparlings8 ,potash is a very active agent in decomposing vegetable matter1 and may be used with great advantage1 especially where an analysis of the soil which is to be manured shows a deficiency of potash4 ,unleached wood ashes are generally the best source from which to obtain this1 and from five to twenty-five bushels of these mixed with one cord of muck will produce the desired result4,z ,the sparlings 7or refuse7 of potash warehouses may often be purchased at sufficiently low rates to be used for this purpose1 and answer an excellent end4 ,they may be applied at the rate of from twenty to one hundred pounds to each cord of muck4 99 99 99 99 99 ,by any of the foregoing methods1 muck may be prepared for use in composting4 ,,footnotes3 ,y ,there is1 undoubtedly1 some of this lime which does not unite with the chlorine2 this1 however1 is still as valuable as any lime4 ,z ,leached ashes will not supply the place of these1 as the leaching has deprived them of their potash4 ,,chapter ,v4 ,,composting ,,stable ,,manure4 ,what principles should regulate us in composting8 ,in what condition is solid dung of value as a fertilizer8 ,what do we aim to do in composting8 ,in composting stable manure in the most economical manner1 the evaporation of the organic parts and the leaching of the ashy 7and other7 portions must be avoided1 while the condition of the mass is such as to admit of the perfect decomposition of the manure4 ,solid manures in their fresh state are of but very little use to plants4 ,it is only as they are decomposed1 and have their nitrogen turned into ammonia1 and their other ingredients resolved into the condition required by plants1 that they are of much value as fertilizers4 ,we have seen that1 if this decomposition takes place without proper precautions being made1 the most valuable parts of the manure would be lost4 ,nor would it be prudent to keep manures from decomposing until they are applied to the soil1 for then they are not immediately ready for use1 and time is lost4 ,by composting1 we aim to save every thing while we prepare the manures for immediate use4 ,,shelter4 ,what is the first consideration for composts8 ,describe the arrangement of floor4 ,the first consideration in preparing for composting1 is to provide proper shelter4 ,this may be done either by means of a shed or by arranging a cellar under the stables1 or in any other manner that may be dictated by circumstances4 ,it is no doubt better to have the manure shed enclosed so as to make it an effectual protection2 this however is not absolutely necessary if the roof project far enough over the compost to shelter it from the sun's rays and from driving rains4 ,the importance of some protection of this kind1 is evident from what has already been said1 and indeed it is impossible to make an economical use of manures without it4 ,the trifling cost of building a shed1 or preparing a cellar1 is amply repaid in the benefit resulting from their uses4 ,,the ,,floor4 ,the floor or foundation on which to build the compost deserves some consideration4 ,it may be of plank tightly fitted1 a hard bed of clay1 or better1 a cemented surface4 ,whatever material is used in its construction 7and stiff clay mixed with water and beaten compactly down answers an excellent purpose71 the floor must have such an inclination as will cause it to discharge water only at one point4 ,that is1 one part of the edge must be lower than the rest of the floor1 which must be so shaped that water will run towards this point from every part of it2 then--the floor being water-tight--all of the liquids of the compost may be collected in a ,,tank4 ,how should the tank be attached8 ,this tank used to collect the liquids of the manure may be made by sinking a barrel or hogshead 7according to the size of the heap7 in the ground at the point where it is required1 or in any other convenient manner4 ,in the tank a pump of cheap construction may be placed1 to raise the liquid to a sufficient height to be conveyed by a trough to the centre of the heap1 and there distributed by means of a perforated board with raised edges1 and long enough to reach across the heap in any direction4 ,by altering the position of this board1 the liquid may be carried evenly over the whole mass4 ,the appearance of the apparatus required for composting1 and the compost laid up1 may be better shown by the following figure4 ,illustration3 ,fig4 #b4 a1 tank2 b1 pump2 c g1 perforated board2 d1 muck2 e1 manure2 f1 floor4 ,how is the compost made8 ,the compost is made by laying on the floor ten or twelve inches of muck1 and on that a few inches of manure1 then another heavy layer of muck1 and another of manure1 continuing in this manner until the heap is raised to the required height1 always having a thick layer of muck at the top4 ,what liquids are best for moistening the compost8 ,how should they be applied8 ,what are the advantages of this moistening8 ,how does it compare with forking over8 ,after laying up the heap1 the tank should be filled with liquid manure from the stables1 slops from the house1 soap-suds1 or other water containing fertilizing matter1 to be pumped over the mass4 ,there should be enough of the liquid to saturate the heap and filter through to fill the tank twice a week1 at which intervals it should be again pumped up1 thus continually being passed through the manure4 ,this liquid should not be changed1 as it contains much soluble manure4 ,should the liquid manures named above not be sufficient1 the quantity may be increased by the use of rain-water4 ,that falling during the first ten minutes of a shower is the best1 as it contains much ammonia4 ,the effects produced by frequently watering the compost is one of the greatest advantages of this system4 ,the soluble portions of the manure are equally diffused through every part of the heap4 ,should the heat of fermentation be too great1 the watering will reduce it4 ,when the compost is saturated with water1 the air is driven out2 and1 as the water subsides1 fresh air enters and takes its place4 ,this fresh air contains oxygen1 which assists in the decomposition of the manure4 ,in short1 the watering does all the work of forking over by hand much better and much more cheaply4 ,why will the ammonia of manure thus made1 not escape if it be used as a top dressing8 ,what are the advantages of preparing manures in this manner8 ,what is the profit attending it8 ,at the end of a month or more1 this compost will be ready for use4 ,the layers in the manure will have disappeared1 the whole mass having become of a uniform character1 highly fertilizing1 and ready to be immediately used by plants4 ,it may be applied to the soil1 either as a top-dressing1 or otherwise1 without fear of loss1 as the muck will retain all of the gases which would otherwise evaporate4 ,the cost and trouble of the foregoing system of composting are trifling compared with its advantages4 ,the quantity of the manure is much increased1 and its quality improved4 ,the health of the animals is secured by the retention of those gases1 which1 when allowed to escape1 render impure the air which they have to breathe4 ,the cleanliness of the stable and yard is much advanced as the effete matters1 which would otherwise litter them1 are carefully removed to the compost4 ,as an instance of the profit of composting1 it may be stated that ,prof4 ,mapes has decomposed ninety-two cords of swamp muck1 with four hundred bushels of the lime and salt mixture1 and then composted it with eight cords of fresh horse dung1 making one hundred cords of manure fully equal to the same amount of stable-manure alone1 which has lain one year exposed to the weather4 ,indeed one cord of muck well decomposed1 and containing the chlorine lime and soda of four bushels of the mixture1 is of itself equal in value to the same amount of manure which has lain in an open barn-yard during the heat and rain of one season1 and is then applied to the land in a raw or undecomposed state4 ,in what other manners may muck be used in the preservation of manures8 ,how may liquid manure be made most useful8 ,the foregoing system of composting is the best that has yet been suggested for making use of solid manures4 ,many other methods may be adopted when circumstances will not admit of so much attention4 ,it is a common and excellent practice to throw prepared muck into the cellar under the stables1 to be mixed and turned over with the manure by swine4 ,in other cases the manures are kept in the yard1 and are covered with a thin layer of muck every morning4 ,the principle which renders these systems beneficial is the absorbent power of charcoal4 ,,liquid ,,manure4 ,liquid manure from animals may1 also1 be made useful by the assistance of prepared muck4 ,where a tank is used in composting1 the liquids from the stable may all be employed to supply moisture to the heap2 but where any system is adopted1 not requiring liquids1 the urine may be applied to muck heaps1 and then allowed to ferment4 ,fermentation is necessary in urine as well as in solid dung1 before it is very active as a manure4 ,urine1 as will be recollected1 contains nitrogen and forms ammonia on fermentation4 ,describe the manner of digging out the bottoms of stalls4 ,it is a very good plan to dig out the bottoms of the stalls in a circular or gutter-like form1 three or four feet deep in the middle1 cement the ground1 or make it nearly water-tight1 by a plastering of stiff clay1 and fill them up with prepared muck4 ,the appearance of a cross section of the floor thus arranged would be as follows3 ,illustration3 ,fig4 #c4 ,the prepared muck in the bottom of the stalls would absorb the urine as soon as voided1 while yet warm with the animal heat1 and receive heat from the animal's body while lying down at night4 ,this heat will hasten the decomposition of the urea1,,aa and if the muck be renewed twice a month1 and that which is removed composted under cover1 it will be found a most prolific source of good manure4 ,in ,flanders1 the liquid manure of a cow is considered worth #aj per year1 and it is not less valuable here4 ,as was stated in the early part of this section1 the inorganic 7or mineral7 matter contained in urine1 is soluble1 and consequently is immediately useful as food for plants4 ,by referring to the analysis of liquid and solid manure1 in section ,v41 their relative value may be seen4 ,,chapter ,,vi4 ,,different ,,kinds ,,of ,,animal ,,excrement4 ,the manures of different animals are1 of course1 of different value1 as fertilizers1 varying according to the food1 the age of the animals1 etc4 ,,stable ,,manure4 ,by stable manure we mean1 usually1 that of the horse1 and that of horned cattle4 ,the case described in chap4 #b 7of this section71 was one where the animal was not increasing in any of its parts1 but returned1 in the form of manure1 and otherwise1 the equivalent of every thing eaten4 ,this case is one of the most simple kind1 and is subject to many modifications4 ,is the manure of full-grown animals of the same quality as that of other animals8 ,why does that of the growing animal differ8 ,why does not the formation of fat reduce the quality of manure8 ,what does milk remove from the food8 ,the growing animal is increasing in size1 and as he derives his increase from his food1 he does not return in the form of manure as much as he eats4 ,if his bones are growing1 he is taking from his food phosphate of lime and nitrogenous matter2 consequently1 the manure will be poorer in these ingredients4 ,the same may be said of the formation of the muscles1 in relation to nitrogen4 ,the fatting animal1 if full grown1 makes manure which is as good as that from animals that are not increasing in size1 because the fat is taken from those parts of the food which is obtained by plants from the atmosphere1 and from nature1 7i4 e4 from the #ast class of proximates74 ,fat contains no nitrogen1 and1 consequently1 does not lessen the amount of this ingredient in the manure4 ,milch ,cows turn a part of their food to the formation of milk1 and consequently1 they produce manure of reduced value4 ,how do the solid and liquid manure of the horse and ox compare8 ,what occasions these differences8 ,the solid manure of the horse is better than that of the ox1 while the liquid manure of the ox is comparatively better than that of the horse4 ,the cause of this is that the horse has poorer digestive organs than the ox1 and consequently passes more of the valuable parts of his food1 in an undigested form1 as dung1 while the ox1 from chewing the cud and having more perfect organs1 turns more of his food into urine than the horse4 ,,recapitulation4 ,,full ,,grown animals not producing milk1 and full make the best manure4 grown animals fattening ,,growing ,,animals reduce the value of their manure1 taking portions of their food to form their bodies4 ,,milch ,,cows reduce the value of their manure by changing a part of their food into milk4 ,,the ,,ox makes poor dung and rich urine4 ,,the ,,horse makes rich dung and poor urine4,,ab ,,night ,,soil4 ,what is the most valuable manure accessible to the farmer8 ,what is the probable value of the night soil yearly lost in the ,united ,states8 ,of what does the manure of man consist8 ,the best manure within the reach of the farmer is night soil1 or human excrement4 ,there has always been a false delicacy about mentioning this fertilizer1 which has caused much waste1 and great loss of health1 from the impure and offensive odors which it is allowed to send forth to taint the air4 ,the value of the night soil yearly lost in the ,united ,states is1 probably1 about fifty millions of dollars 7#ej1jjj1jjj72 an amount nearly equal to the entire expenses of our ,national ,government4 ,much of the ill health of our people is undoubtedly occasioned by neglecting the proper treatment of night soil4 ,describe this manure as compared with the excrements of other animals4 ,does the use of night soil produce disagreeable properties in plants8 ,that which directly affects agriculture1 as treated of in this book1 is the value of this substance as a fertilizer4 ,the manure of man consists 7as is the case with that of other animals7 of those parts of his food which are not retained in the increase of his body4 ,if he be growing1 his manure is poorer1 as in the case of the ox1 and it is subject to all the other modifications named in the early part of this chapter4 ,his food is usually of a varied character1 and is rich in nitrogen1 the phosphates1 and other inorganic constituents2 consequently1 his manure is made valuable by containing large quantities of these matters4 ,as is the case with the ox1 the dung contains the undigested food1 the secretions 7or leakings7 of the digestive organs1 and the insoluble parts of the ash of the digested food4 ,the urine1 in like manner1 contains a large proportion of the nitrogen and the soluble inorganic parts of the digested food4 ,when we consider how much richer the food of man is than that of horned cattle1 we shall see the superior value of his excrement4 ,night soil has been used as a manure1 for ages1 in ,china1 which is1 undoubtedly1 one great secret of their success in supporting a dense population1 for so long a time1 without impoverishing the soil4 ,it has been found1 in many instances1 to increase the productive power of the natural soil three-fold4 ,that is1 if a soil would produce ten bushels of wheat per acre1 without manure1 it would produce thirty bushels if manured with night soil4 ,some have supposed that manuring with night soil would give disagreeable properties to plants3 such is not the case2 their quality is invariably improved4 ,the color and odor of the rose become richer and more delicate by the use of the most offensive night soil as manure4 ,what is the direct object of plants8 ,what would result if this were not the case8 ,how may night soil be easily prepared for use1 and its offensive odor prevented8 ,it is evident that this is the case from the fact that plants have it for their direct object to make over and put together the refuse organic matter1 and the gases and the minerals found in nature1 for the use of animals4 ,if there were no natural means of rendering the excrement of animals available to plants1 the earth must soon be shorn of its fertility1 as the elements of growth when once consumed would be essentially destroyed1 and no soil could survive the exhaustion4 ,there is no reason why the manure of man should be rejected by vegetation more than that of any other animal2 and indeed it is not1 for ample experience has proved that for most soils there is no better manure in existence4 ,a single experiment will suffice to show that night soil may be so kept that there shall be no loss of its valuable gases1 and consequently no offensive odor arising from it1 while it may be removed and applied to crops without unpleasantness4 ,all that is necessary to effect this wonderful change in night soil1 and to turn it from its disagreeable character to one entirely inoffensive1 is to mix with it a little charcoal dust1 prepared muck1 or any other good absorbent--thus making what is called poudrette4 ,the mode of doing this must depend on circumstances4 ,in many cases1 it would be expedient to keep a barrel of the absorbent in the privy and throw down a small quantity every day4 ,the effect on the odor of the house would amply repay the trouble4 ,should pure night soil be used as a manure8 ,what precaution is necessary in preparing hog manure for use8 ,the manure thus made is of the most valuable character1 and may be used under any circumstances with a certainty of obtaining a good crop4 ,it should not be used unmixed with some absorbent1 as it is of such strength as to kill plants4 ,for an analysis of human manure1 see ,section ,v4 ,,hog ,,manure4 ,hog ,manure is very valuable1 but it must be used with care4 ,it is so violent in its action that1 when applied in a pure form to crops1 it often produces injurious results4 ,it is liable to make cabbages clump-footed1 and to induce a disease in turnips called ambury 7or fingers and toes74 ,the only precaution necessary is to supply the stye with prepared muck1 charcoal-dust1 leaf-mould1 or any absorbent in plentiful quantities1 often adding fresh supplies4 ,the hogs will work this over with the manure2 and1 when required for use1 it will be found an excellent fertilizer4 ,the absorbent will have overcome its injurious tendency1 and it may be safely applied to any crop4 ,from the variety and rich character of the food of this animal1 his manure is of a superior quality4 ,why is the manure from butchers' hog-pens very valuable8 ,how does the value of poultry manure compare with that of guano8 ,how may it be protected against loss8 ,butchers' hog-pen manure is one of the best fertilizers known4 ,it is made by animals that live almost entirely on blood and other animal refuse1 and is very rich in nitrogen and the phosphates4 ,it should be mixed with prepared muck1 or its substitute1 to prevent the loss of its ammonia1 and as a protection against its injurious effect on plants4 ,,poultry ,,house ,,manure4 ,next in value to night soil1 among domestic manures1 are the excrements of poultry1 pigeons1 etc4 ,birds live on the nice bits of creation1 seeds1 insects1 etc41 and they discharge their solid and liquid excrements together4 ,poultry-dung is nearly equal in value to guano 7except that it contains more water71 and it deserves to be carefully preserved and judiciously used4 ,it is as well worth twenty-five cents per bushel as guano is worth fifty dollars a ton 7at which price it is now sold74 ,poultry-manure is liable to as much injury from evaporation and leaching as is any other manure1 and equal care should be taken 7by the same means7 to prevent such loss4 ,good shelter over the roosts1 and daily sprinkling with prepared muck or charcoal-dust will be amply repaid by the increased value of the manure1 and its better action and greater durability in the soil4 ,the value of this manure should be taken into consideration in calculating the profit of keeping poultry 7as indeed with all other stock74 ,it has been observed by a gentleman of much experience1 in poultry raising1 that the yearly manure of a hundred fowls applied to previously unmanured land would produce extra corn enough to keep them for a year4 ,this is probably a large estimate1 but it serves to show that this fertilizer is very valuable1 and also that poultry may be kept with great profit1 if their excrements are properly secured4 ,the manure of pigeons has been a favorite fertilizer in some countries for more than #bjjj years4 ,market gardeners attach much value to rabbit-manure4 ,,sheep ,,manure4 ,what can you say of the manure of sheep8 ,the manure of sheep is less valuable than it would be1 if so large a quantity of the nitrogen and mineral parts of the food were not employed in the formation of wool4 ,this has a great effect on the richness of the excrements1 but they are still a very good fertilizer1 and should be protected from loss in the same way as stable manure4 ,,guano4 ,should the use of guano induce us to disregard other manures8 ,where and in what manner is the best guano deposited8 ,guano as a manure has become world renowned4 ,the worn-out tobacco lands of ,virginia1 and other fields in many parts of the country1 which seemed to have yielded to the effect of an ignorant course of cultivation1 and to have sunk to their final repose1 have in many cases been revived to the production of excellent crops1 and have had their value multiplied many fold by the use of guano4 ,although an excellent manure1 it should not cause us to lose sight of those valuable materials which exist on almost every farm4 ,every ton of guano imported into the ,united ,states is an addition to our national wealth1 but every ton of stable-manure1 or poultry-dung1 or night soil evaporated or carried away in rivers1 is equally a deduction from our riches4 ,if the imported manure is to really benefit us1 we must not allow it to occasion the neglect and consequent loss of our domestic fertilizers4 ,the ,peruvian guano 7which is considered the best7 is brought from islands near the coast of ,peru4 ,the birds which frequent these islands live almost entirely on fish1 and drop their excrements here in a climate where rain is almost unknown1 and where1 from the dryness of the air1 there is but little loss sustained by the manure4 ,it is brought to this country in large quantities1 and is an excellent fertilizer1 superior even to night soil4 ,how should it be prepared for use8 ,it should be mixed with an absorbent before being used1 unless it is plowed deeply under the soil1 as it contains much ammonia which would be lost from evaporation4 ,it would probably also injure plants4 ,the best way to use guano1 is in connection with sulphuric acid and bones1 as will be described hereafter4 ,the composition of the various kinds of guano may be found in the section on analysis4 ,,footnotes3 ,,aa ,the nitrogenous compound in the urine4 ,,ab ,comparatively4 ,,chapter ,,vii4 ,,other ,,organic ,,manures4 ,the number of organic manures is almost countless4 ,the most common of these have been described in the previous chapters on the excrements of animals4 ,the more prominent of the remaining ones will now be considered4 ,as a universal rule1 it may be stated that all organic matter 7every thing which has had vegetable or animal life7 is capable of fertilizing plants4 ,,dead ,,animals4 ,what are the chief fertilizing constituents of dead animals8 ,what becomes of these when exposed to the atmosphere8 ,how may this be prevented8 ,the bodies of animals contain much nitrogen1 as well as valuable quantities1 the phosphates and other inorganic materials required in the growth of plants4 ,on their decay1 the nitrogen is resolved into ammonia1,,ac and the mineral matters become valuable as food for the inorganic parts of plants4 ,if the decomposition of animal bodies takes place in exposed situations1 and without proper precautions1 the ammonia escapes into the atmosphere1 and much of the mineral portion is leached out by rains4 ,the use of absorbents1 such as charcoal-dust1 prepared muck1 etc41 will entirely prevent evaporation1 and will in a great measure serve as a protection against leaching4 ,if a dead horse be cut in pieces and mixed with ten loads of muck1 the whole mass will1 in a single season1 become a most valuable compost4 ,small animals1 such as dogs1 cats1 etc41 may be with advantage buried by the roots of grape-vines or trees4 ,,bones4 ,of what do the bones of animals consist8 ,what is gelatine8 ,describe the fertilizing qualities of fish4 ,the bones of animals contain phosphate of lime and gelatine4 ,the gelatine is a nitrogenous substance1 and produces ammonia on its decomposition4 ,this subject will be spoken of more fully under the head of 'phosphate of lime' in the chapter on mineral manures1 as the treatment of bones is more directly with reference to the fertilizing value of their inorganic matter4 ,,fish4 ,in many localities near the sea-shore large quantities of fish are caught and applied to the soil4 ,these make excellent manure4 ,they contain much nitrogen1 which renders them strongly ammoniacal on decomposition4 ,their bones consist of phosphate and carbonate of lime2 and1 being naturally soft1 they decompose in the soil with great facility1 and become available to plants4 ,the scales of fish contain valuable quantities of nitrogen1 phosphate of lime1 etc41 all of which are highly useful4 ,refuse fishy matters from markets and from the house are well worth saving4 ,these and fish caught for manure may be made into compost with prepared muck1 etc42 and1 as they putrefy rapidly1 they soon become ready for use4 ,they may be added to the compost of stable manure with great advantage4 ,should these be applied as a top dressing to the soil8 ,what are the fertilizing properties of woollen rags8 ,what is the best way to use them8 ,fish 7like all other nitrogenous manures7 should never be applied as a top dressing1 unless previously mixed with a good absorbent of ammonia1 but should when used alone be immediately plowed under to considerable depth1 to prevent the evaporation--and consequent loss--of their fertilizing gases4 ,,woollen ,,rags1 ,,etc4 ,woollen rags1 hair1 waste of woollen factories1 etc41 contain both nitrogen and phosphate of lime2 and1 like all other matters containing these ingredients1 are excellent manures1 but must be used in such a way as to prevent the escape of their fertilizing gases4 ,they decompose slowly1 and are therefore considered a lasting manure4 ,like all lasting manures1 however1 they are slow in their effects1 and the most advantageous way to use them is to compost them with stable manure1 or with some other rapidly fermenting substance1 which will hasten their decomposition and render them sooner available4 ,rags1 hair1 etc41 thus treated1 will in a short time be reduced to such a condition that they may be immediately used by plants instead of lying in the soil to be slowly taken up4 ,it is better in all cases to have manures act quickly and give an immediate return for their cost1 than to lie for a long time in the soil before their influence is felt4 ,what is their value compared with that of farm-yard manure8 ,how should old leather be treated8 ,describe the manurial properties of tanners' refuse4 ,how should they be treated8 ,are horn piths1 etc4 valuable8 ,a pound of woollen rags is worth1 as a manure1 twice as much as is paid for good linen shreds for paper making2 still1 while the latter are always preserved1 the former are thrown away1 although considered by good judges to be worth forty times as much as barn-yard manure4 ,old leather should not be thrown away4 ,it decomposes very slowly1 and consequently is of but a little value2 but1 if put at the roots of young trees1 it will in time produce appreciable effects4 ,tanners' and curriers' refuse1 and all other animal offal1 including that of the slaughter-house1 is well worth attention1 as it contains more or less of those two most important ingredients of manures1 nitrogen and phosphate of lime4 ,it is unnecessary to add that1 in common with all other animal manures1 these substances must be either composted1 or immediately plowed under the soil4 ,horn piths1 and horn shavings1 if decomposed in compost1 with substances which ferment rapidly1 make very good manure1 and are worth fully the price charged for them4 ,,organic ,,manures ,,of ,,vegetable ,,origin4 ,muck1 the most important of the purely vegetable manures1 has been already sufficiently described4 ,it should be particularly borne in mind that1 when first taken from the swamp it is often sour1 or cold1 but that if exposed for a long time to the air1 or if well treated with lime1 unleached ashes1 the lime and salt mixture1 or any other alkali1 its acids will be neutralized 7or overcome71 and it becomes a good application to any soil1 except peat or other soils already containing large quantities of organic matter4 ,in applying muck to the soil 7as has been before stated71 it should be made a vehicle for carrying ammoniacal manures4 ,,spent ,,tan ,,bark4 ,why is decomposed bark more fertilizing than that of decayed wood8 ,spent tan bark1 if previously decomposed by the use of the lime and salt mixture1 or potash1 answers all the purposes of prepared muck1 but is more difficult of decomposition4 ,how may bark be decomposed8 ,why should tan bark be composted with an alkali8 ,why is it good for mulching8 ,is sawdust of any value8 ,the bark of trees contains a larger proportion of inorganic matter than the wood1 and much of this1 on the decomposition of the bark1 becomes available as manure4 ,the chemical effect on the bark1 of using it in the tanning of leather1 is such as to render it difficult to be rotted by the ordinary means1 but1 by the use of the lime and salt mixture it may be reduced to the finest condition1 and becomes a most excellent manure4 ,it probably contains small quantities of nitrogen 7obtained from the leather71 which adds to its value4 ,unless tan bark be composted with lime1 or some other alkali1 it may produce injurious effects from the tannic acid which it is liable to contain4 ,alkaline substances will neutralize this acid1 and prevent it from being injurious4 ,one great benefit resulting from the use of spent tan bark1 is due to its power of absorbing moisture from the atmosphere4 ,for this reason it is very valuable for mulching,,ad young trees and plants when first set out4 ,,sawdust4 ,why is sawdust a good addition to the pig-stye8 ,what is the peculiarity of sawdust from the beech1 etc48 ,what is a peculiarity of soot8 ,why may soot be used as a top dressing without losing its ammonia8 ,sawdust in its natural state is of very little value to the land1 but when decomposed1 as may be done by the same method as was described for tan bark1 it is of some importance1 as it contains a large quantity of carbon4 ,its ash1 too1 which becomes available1 contains soluble inorganic matter1 and in this way it acts as a direct manure4 ,so far as concerns the value of the ash1 however1 the bark is superior to sawdust4 ,sawdust may be partially rotted by mixing it with strong manure 7as hog manure71 while it acts as a divisor1 and prevents the too rapid action of this when applied to the soil4 ,some kinds of sawdust1 such as that from beech wood1 form acetic acid on their decomposition1 and these should be treated with1 at least1 a sufficient quantity of lime to correct the acid4 ,soot is a good manure4 ,it contains much carbon1 and has1 thus far1 all of the beneficial effects of charcoal dust4 ,the sulphur1 which is one of its constituents1 not only serves as food for plants1 but1 from its odor1 is a good protection against some insects4 ,by throwing a handful of soot on a melon vine1 or young cabbage plant1 it will keep away many insects4 ,soot contains some ammonia1 and as this is in the form of a sulphate1 it is not volatile1 and consequently does not evaporate when the soot is applied as a top dressing1 which is the almost universal custom4 ,,green ,,crops4 ,what plants are most used as green crops8 ,what office is performed by the roots of green crops8 ,how do such manures increase the organic matter of soils8 ,green crops1 to plow under1 are in many places largely raised1 and are always beneficial4 ,the plants most used for this purpose1 in our country1 are clover1 buckwheat1 and peas4 ,these plants have very long roots1 which they send deep in the soil1 to draw up mineral matter for their support4 ,this mineral matter is deposited in the plant4 ,the leaves and roots receive carbonic acid and ammonia from the air1 and from water4 ,in this manner they obtain their carbon4 ,when the crop is turned under the soil1 it decomposes1 and the carbon1 as well as the mineral ingredients obtained from the subsoil1 are deposited in the surface soil1 and become of use to succeeding crops4 ,the hollow stalks of the buckwheat and pea1 serve as tubes1 in the soil1 for the passage of air1 and thus1 in heavy soils1 give a much needed circulation of atmospheric fertilizers4 ,what office is performed by the straw of the buckwheat and pea8 ,what treatment may be substituted for the use of green crops8 ,which course should be adopted in high farming8 ,why is the use of green crops preferable in ordinary cultivation8 ,name some other valuable manures4 ,although green crops are of great benefit1 and are managed with little labor1 there is no doubt but the same results may be more economically produced4 ,a few loads of prepared muck will do more towards increasing the organic matter in the soil1 than a very heavy crop of clover1 while it would be ready for immediate cultivation1 instead of having to lie idle during the year required in the production and decomposition of the green crop4 ,the effect of the roots penetrating the subsoil is1 as we have seen1 to draw up inorganic matter1 to be deposited within reach of the roots of future crops4 ,in the next section we shall show that this end may be much more efficiently attained by the use of the sub-soil plow1 which makes a passage for the roots into the subsoil1 where they can obtain for themselves what would1 in the other case1 be brought up for them by the roots of the green crop4 ,the offices of the hollow straws may be performed by a system of ridging and back furrowing1 having previously covered the soil with leaves1 or other refuse organic material4 ,in high farming1 where the object of the cultivator is to make a profitable investment of labor1 these last named methods will be found most expedient2 but1 if the farmer have a large quantity of land1 and can afford but a limited amount of labor1 the raising of green crops1 to be plowed under in the fall1 will probably be adopted4 ,before closing this chapter1 it may be well to remark that there are various other fertilizers1 such as the ammoniacal liquor of gas-houses1 soapers' wastes1 bleachers' lye1 lees of old oil casks1 etc41 which we have not space to consider at length1 but which are all valuable as additions to the compost heap1 or as applications1 in a liquid form1 to the soil4 ,what are the advantages arising from burying manure in its green state8 ,which is generally preferable1 this course1 or composting8 ,why8 ,in many cases 7when heavy manuring is practised71 it may be well to apply organic manures to the soil in a green state1 turn them under1 and allow them to undergo decomposition in the ground4 ,the advantages of this system are1 that the heat1 resulting from the chemical changes1 will hasten the growth of plants1 by making the soil warmer2 the carbonic acid formed will be presented to the roots instead of escaping into the atmosphere2 and if the soil be heavy1 the rising of the gases will tend to loosen it1 and the leaving vacant of the spaces occupied by the solid matters will1 on their being resolved into gases1 render the soil of a more porous character4 ,as a general rule1 however1 in ordinary farming1 where the amount of manure applied is only sufficient for the supply of food to the crop1 it is undoubtedly better to have it previously decomposed--cooked as it were1 for the uses of the plants--as they can then obtain the required amount of nutriment as fast as needed4 ,,absorption ,,of ,,moisture4 ,it is often convenient to know the relative power of different manures to absorb moisture from the atmosphere1 especially when we wish to manure lands that suffer from drought4 ,the following results are given by ,c4 ,w4 ,johnson1 in his essay on salt1 7pp4 #h and #ai74 ,in these experiments the animal manures were employed without any admixture of straw4 ,,parts #ajjj parts of horse dung1 dried in a temperature of #ajj1 absorbed by exposure for three hours1 to air saturated with moisture1 of the temperature of #fb #ade #ajjj parts of cow dung1

,muck is a most excellent absorbent of moisture1 when thoroughly decomposed4 ,,distribution ,,of ,,manures4 ,the following table from ,johnson1 on manures1 will be found convenient in the distribution of manures4 ,by its assistance the farmer will know how many loads of manure he requires1 dividing each load into a stated number of heaps1 and placing them at certain distances4 ,in this manner manure may be applied evenly1 and calculation may be made as to the amount1 per acre1 which a certain quantity will supply4,,af ---------------------------------------- -----------------------------

book4 ,,ae ,working ,farmer1 vol4 #a1 p4 #ee4 ,,af ,it is not necessary that this and the foregoing table should be learned by the scholar1 but they will be found valuable for reference by the farmer4 ,,chapter ,,viii4 ,,mineral ,,manures4 ,how many kinds of action have inorganic manures8 ,what is the first of these8 ,the second8 ,third8 ,fourth8 ,do all mineral manures possess all of these qualities8 ,the second class of manures named in the general division of the subject1 in the early part of this chapter1 comprises those of a mineral character1 or inorganic manures4 ,these manures have four kinds of action when applied to the soil4 #ast4 ,they furnish food for the inorganic part of plants4 #b;d4 ,they prepare matters already in the soil1 for assimilation by roots4 #c;d4 ,they improve the mechanical condition of the soil4 #dth4 ,they absorb ammonia4 ,some of the mineral manures produce in the soil only one of these effects1 and others are efficient in two or all of them4 ,the principles to be considered in the use of mineral manures are essentially given in the first two sections of this book4 ,it may be well1 however1 to repeat them briefly in this connection1 and to give the reasons why any of these manures are needed1 from which we may learn what rules are to be observed in their application4 ,relate what you know of the properties of vegetable ashes8 ,how does this relate to the fertility of the soil8 ,according to what two rules may we apply mineral manures8 ,what course would you pursue to raise potatoes on a soil containing a very little phosphoric acid and no potash8 #ast4 ,those which are used as food by plants4 ,it will be recollected that the ash left after burning plants1 and which formed a part of their structures1 has a certain chemical composition2 that is1 it consists of alkalies1 acids1 and neutrals4 ,it was also stated that the ashes of plants of the same kind are always of about the same composition1 while the ashes of different kinds of plants may vary materially4 ,different parts of the same plant too1 as we learned1 are supplied with different kinds of ash4 ,for instance1 clover1 on being burned1 leaves an ash containing lime1 as one of its principal ingredients1 while the ash of potatoes contains more of potash than of any thing else4 ,in the second section 7on soils71 we learned that some soils contain every thing necessary to make the ashes of all plants1 and in sufficient quantity to supply what is required1 while other soils are either entirely deficient in one or more ingredients1 or contain so little of them that they are unfertile for certain plants4 ,would you manure it in the same way for wheat8 ,why8 ,from this1 we see that we may pursue either one of two courses4 ,after we know the exact composition of the soil--which we can learn only from correct analysis--we may manure it with a view either to making it fertile for all kinds of plants or only for one particular plant4 ,for instance1 we may find that a soil contains a very little phosphoric acid1 and no potash4 ,if we wish to raise potatoes on such a soil1 we have only to apply potash 7if the soil is good in other particulars71 which is largely required by this plant1 though it needs but little phosphoric acid2 while1 if we wish to make it fertile for wheat1 and all other plants1 we must apply more phosphoric acid as well as potash4 ,as a universal rule1 it may be stated that to render a soil fertile for any particular plant1 we must supply it 7unless it already contains them7 with those matters which are necessary to make the ash of that plant2 and1 if we would render it capable of producing all kinds of plants1 it must be furnished with the materials required in the formation of all kinds of vegetable ashes4 ,it is not absolutely necessary to have the soil analyzed before it can be cultivated with success1 but it is the cheapest way4 ,how is the fertility of the soil to be maintained1 if the crops are sold8 ,what rule is given for general treatment8 ,give an instance of matters in the soil that are to be rendered available by mineral manures8 ,we might proceed from an analysis of the plant required 7which will be found in ,section ,v471 and apply to the soil in the form of manure every thing that is necessary for the formation of the ash of that plant4 ,this would give a good crop on any soil that was in the proper mechanical condition1 and contained enough organic matter2 but a moment's reflection will show that1 if the soil contained a large amount of potash1 or of phosphate of lime1 it would not be necessary to make an application of more of these ingredients--at an expense of perhaps three times the cost of an analysis4 ,it is true that1 if the crop is sold1 and it is desired to maintain the fertility of the soil1 the full amount of the ash must be applied1 either before or after the crop is grown2 but1 in the ordinary use of crops for feeding purposes1 a large part of the ash will exist in the excrements of the animals2 so that the judicious farmer will be able to manure his land with more economy than if he had to apply to each crop the whole amount and variety required for its ash4 ,the best rule for practical manuring is probably to strengthen the soil in its weaker points1 and prevent the stronger ones from becoming weaker4 ,in this way1 the soil may be raised to the highest state of fertility1 and be fully maintained in its productive powers4 #b;d4 ,those manures which render available matter already contained in the soil4 ,how may silica be developed8 ,how does lime affect soils containing coarse particles8 ,how do mineral manures sometimes improve the mechanical texture of the soil8 ,silica 7or sand71 it will be recollected1 exists in all soils2 but1 in its pure state1 is not capable of being dissolved1 and therefore cannot be used by plants4 ,the alkalies 7as has been stated71 have the power of combining with this silica1 making compounds1 which are called silicates4 ,these are readily dissolved by water1 and are available in vegetable growth4 ,now1 if a soil is deficient in these soluble silicates1 it is well known that grain1 etc41 grown on it1 not being able to obtain the material which gives them strength1 will fall down or lodge2 but1 if such measures be taken1 as will render the sand soluble1 the straw will be strong and healthy4 ,alkalies used for this purpose1 come under the head of those manures which develope the natural resources of the soil4 ,again1 much of the mineral matter in the soil is combined within particles1 and is therefore out of the reach of roots4 ,lime1 among other thing1 has the effect of causing these particles to crumble and expose their constituents to the demand of roots4 ,therefore1 lime has for one of its offices the development of the fertilizing ingredients of the soil4 #c;d4 ,those manures which improve the mechanical condition of the soil4 ,the alkalies1 in combining with sand1 commence their action on the surfaces of the particles1 and roughen them--rust them as it were4 ,this roughening of particles of the soil prevents them from moving among each other as easily as they do when they are smooth1 and thus keeps the soil from being compacted by heavy rains1 as it is liable to be in its natural condition4 ,in this way1 the mechanical texture of the soil is improved4 ,it has just been said that lime causes the pulverization of the particles of the soil2 and thus1 by making it finer1 improves its mechanical condition4 ,some mineral manures1 as plaster and salt1 have the power of absorbing moisture from the atmosphere2 and this is a mechanical improvement to dry soils4 ,name some mineral manures which absorb ammonia8 #dth4 ,those mineral manures which have the power of absorbing ammonia4 ,plaster1 chloride of lime1 alumina 7clay71 etc41 are large absorbents of ammonia1 whether arising from the fermentation of animal manures or washed down from the atmosphere by rains4 ,the ammonia thus absorbed is of course very important in the vegetation of crops4 ,having now explained the reasons why mineral manures are necessary1 and the manner in which they produce their effects1 we will proceed to examine the various deficiencies of soils and the character of many kinds of this class of fertilizers4 ,,chapter ,,ix4 ,,deficiencies ,,of ,,soils1 ,,means ,,of ,,restoration1 ,,etc4 ,as will be seen by referring to the analyses of soils on p4 #gb1 they may be deficient in certain ingredients1 which it is the object of mineral manures to supply4 ,these we will take up in order1 and endeavor to show in a simple manner the best means of managing them in practical farming4 ,,alkalies4 ,,potash4 ,do all soils contain a sufficient amount of potash8 ,how may its deficiency have been caused8 ,how may its absence be detected8 ,does barn-yard manure contain sufficient potash to supply its deficiency in worn-out soils8 ,potash is often deficient in the soil4 ,its deficiency may have been caused in two ways4 ,either it may not have existed largely in the rock from which the soil was formed1 and consequently is equally absent from the soil itself1 or it may have once been present in sufficient quantities1 and been carried away in crops1 without being returned to the soil in the form of manure until too little remains for the requirements of fertility4 ,in either case1 its absence may be accurately detected by a skilful chemist1 and it may be supplied by the farmer in various ways4 ,potash1 as well as all of the other mineral manures1 is contained in the excrements of animals1 but not 7as is also the case with the others7 in sufficient quantities to restore the proper balance to soils where it is largely deficient1 nor even to make up for what is yearly removed with each crop1 except that crop 7or its equivalent7 has been fed to such animals as return all of the fertilizing constituents of their food in the form of manure1 and this be all carefully preserved and applied to the soil4 ,in all other cases1 it is necessary to apply more potash than is contained in the excrements of animals4 ,what is generally the most available source from which to obtain this alkali8 ,will leached ashes answer the same purpose8 ,how may ashes be used8 ,unleached wood ashes is generally the most available source from which to obtain this alkali4 ,the ashes of all kinds of wood contain potash 7more or less according to the kind--see analysis section ,v47 ,if the ashes are leached1 the potash is removed2 and1 hence for the purpose of supplying it1 they are worthless2 but unleached ashes are an excellent source from which to obtain it4 ,they may be made into compost with muck1 as directed in a previous chapter1 or applied directly to the soil4 ,in either case the potash is available directly to the plant1 or is capable of uniting with the silica in the soil to form silicate of potash4 ,neither potash nor any other alkali should ever be applied to animal manures unless in compost with an absorbent1 as they cause the ammonia to be thrown off and lost4 ,from what other sources may potash be obtained8 ,how may we obtain soda8 ,in what quantities should pure salt be applied to the soil8 ,potash sparlings1 or the refuse of potash warehouses1 is an excellent manure for lands deficient in this constituent4 ,potash marl1 such as is found in ,new ,jersey1 contains a large proportion of potash1 and is an excellent application to soils requiring it4 ,feldspar1 kaolin1 and other minerals containing potash1 are1 in some localities1 to be obtained in sufficient quantities to be used for manurial purposes4 ,granite contains potash1 and if it can be crushed 7as is the case with some of the softer kinds17 it serves a very good purpose4 ,,soda4 ,if applied in large quantities will it produce permanent injury8 ,in what quantities should salt be applied to composts8 ,to asparagus8 ,soda1 the requirement of which is occasioned by the same causes as create a deficiency of potash1 and all of the other ingredients of vegetable ashes1 may be very readily supplied by the use of common salt 7chloride of sodium71 which consists of about one half sodium 7the base of soda74 ,the best way to use salt is in the lime and salt mixture1 previously described1 or as a direct application to the soil4 ,if too much salt be given to the soil it will kill any plant4 ,in small quantities1 however1 it is highly beneficial1 and if six bushels per acre be sown broadcast over the land1 to be carried in by rains and dews1 it will not only destroy many insects 7grubs1 worms1 etc471 but will1 after decomposing and becoming chlorine and soda1 prove an excellent manure4 ,salt1 even in quantities large enough to denude the soil of all vegetation1 is never permanently injurious4 ,after the first year1 it becomes resolved into its constituents1 and furnishes chlorine and soda to plants1 without injuring them4 ,one bushel of salt in each cord of compost will not only hasten the decomposition of the manures1 but will kill all seeds and grubs--a very desirable effect4 ,while small quantities of salt in a compost heap are beneficial1 too much 7as when applied to the soil7 is positively injurious1 as it arrests decomposition2 fairly pickles the manures1 and prevents them from rotting4 ,what is generally the best way to use salt8 ,what is nitrate of soda8 ,what plants contain lime8 ,for asparagus1 which is a marine plant1 salt is an excellent manure1 and may be applied in almost unlimited quantities1 while the plants are growing1 if used after they have gone to top1 it is injurious4 ,salt has been applied to asparagus beds in such quantities as to completely cover them1 and with apparent benefit to the plants4 ,of course large doses of salt kill all weeds1 and thus save labor and the injury to the asparagus roots1 which would result from their removal by hoeing4 ,salt may be used advantageously in any of the foregoing manners1 but should always be applied with care4 ,for ordinary farm purposes1 it is undoubtedly most profitable to use the salt with lime1 and make it perform the double duty of assisting in the decomposition of vegetable matter1 and fertilizing the soil4 ,soda unites with the silica in the soil1 and forms the valuable silicate of soda4 ,nitrate of soda1 or cubical nitre1 which is found in ,south ,america1 consists of soda and nitric acid4 ,it furnishes both soda and nitrogen to plants1 and is an excellent manure4 ,,lime4 ,the subject of lime is one of most vital importance to the farmer2 indeed1 so varied are its modes of action and its effects1 that some writers have given it credit for every thing good in the way of farming1 and have gone so far as to say that all permanent improvement of agriculture must depend on the use of lime4 ,although this is far in excess of the truth 7as lime cannot plow1 nor drain1 nor supply any thing but lime to the soil71 its many beneficial effects demand for it the closest attention4 ,do all soils contain enough lime for the use of plants8 ,what amount is needed for this purpose8 ,what is its first-named effect on the soil8 ,its second8 ,third8 ,fourth8 ,fifth8 ,how are acids produced in the soil8 ,as food for plants1 lime is of considerable importance4 ,all plants contain lime--some of them in large quantities4 ,it is an important constituent of straw1 meadow hay1 leaves of fruit trees1 peas1 beans1 and turnips4 ,it constitutes more than one third of the ash of red clover4 ,many soils contain lime enough for the use of plants1 in others it is deficient1 and must be supplied artificially before they can produce good crops of those plants of which lime is an important ingredient4 ,the only way in which the exact quantity of lime in the soil can be ascertained is by chemical analysis4 ,however1 the amount required for the mere feeding plants is not large1 7much less than one per cent471 but lime is often necessary for other purposes2 and setting aside1 for the present1 its feeding action1 we will examine its various effects on the mechanical and chemical condition of the soil4 #a4 ,it corrects acidity 7sourness74 #b4 ,it hastens the decomposition of the organic matter in the soil4 #c4 ,it causes the mineral particles of the soil to crumble4 #d4 ,by producing the above effects1 it prepares the constituents of the soil for assimilation by plants4 #e4 ,it is said to exhaust the soil1 but it does so in a very desirable manner1 the injurious effects of which may be easily avoided4 ,how does lime correct them8 ,how does it affect animal manures in the soil8 #a4 ,the decomposition of organic matter in the soil1 often produces acids which makes the land sour1 and cause it to produce sorrel and other weeds1 which interfere with the healthy growth of crops4 ,lime is an alkali1 and if applied to soils suffering from sourness1 it will unite with the acids1 and neutralize them1 so that they will no longer be injurious4 #b4 ,we have before stated that lime is a decomposing agent1 and hastens the rotting of muck and other organic matter4 ,it has the same effect on the organic parts of the soil1 and causes them to be resolved into the gases and minerals of which they are formed4 ,it has this effect1 especially1 on organic matters containing nitrogen1 causing them to throw off ammonia2 consequently1 it liberates this gas from the animal manures in the soil4 #c4 ,various inorganic compounds in the soil are so affected by lime1 that they lose their power of holding together1 and crumble1 or are reduced to finer particles1 while some of their constituents are rendered soluble4 ,one way in which this is accomplished is by the action of the lime on the silica contained in these compounds1 forming the silicate of lime4 ,this crumbling effect improves the mechanical as well as the chemical condition of the soil4 #d4 ,we are now enabled to see how lime prepares the constituents of the soil for the use of plants4 ,inorganic compounds8 ,how does lime prepare the constituents of the soil for use8 ,what can you say of the remark that lime exhausts the organic matter in the soil8 ,by its action on the roots1 buried stubble1 and other organic matter in the soil1 it causes them to be decomposed1 and to give up many of their gaseous and inorganic constituents for the use of roots4 ,in this manner the organic matter is prepared for use more rapidly than would be the case1 if there were no lime present to hasten its decomposition4 ,by the decomposing action of lime on the mineral parts of the soil 7#c71 they also are placed more rapidly in a useful condition than would be the case1 if their preparation depended on the slow action of atmospheric influences4 ,thus1 we see that lime1 aside from its use directly as food for plants1 exerts a beneficial influence on both the organic and inorganic parts of the soil4 #e4 ,many contend that lime exhausts the soil4 ,if we examine the manner in which it does so1 we shall see that this is no argument against its use4 ,how can lime exhaust the mineral parts of the soil8 ,must the matter taken away be returned to the soil8 ,it exhausts the organic parts of the soil1 by decomposing them1 and resolving them into the gases and minerals of which they are composed4 ,if the soil do not contain a sufficient quantity of absorbent matter1 such as clay or charcoal1 the gases arising from the organic matter are liable to escape2 but when there is a sufficient amount of these substances present 7as there always should be71 these gases are all retained until required by the roots of plants4 ,hence1 although the organic matter of manure and vegetable substances may be altered in form1 by the use of lime1 it can escape 7except in very poor soils7 only as it is taken up by roots to feed the crop1 and such exhaustion is certainly profitable2 still1 in order that the fertility of the soil may be maintained1 enough of organic manure should be applied1 to make up for the amount taken from the soil by the crop1 after liberation for its use by the action of the lime4 ,this will be but a small proportion of the organic matter contained in the crop1 as it obtains the larger part from the atmosphere4 ,the only way in which lime can exhaust the inorganic part of the soil is1 by altering its condition1 so that plants can use it more readily4 ,that is1 it exposes it for solution in water4 ,we have seen that fertilizing matter cannot be leached out of a good soil1 in any material quantity1 but can only be carried down to a depth of about thirty-four inches4 ,hence1 we see that there can be no loss in this direction2 and1 as inorganic matter cannot evaporate from the soil1 the only way in which it can escape is through the structure of plants4 ,if this course be pursued1 will the soil suffer from the use of lime8 ,is it the lime1 or its crop1 that exhausts the soil8 ,is lime containing magnesia better than pure lime8 ,what is the best kind of lime8 ,if lime is applied to the soil1 and increases the amount of crops grown by furnishing a larger supply of inorganic matter1 of course1 the removal of inorganic substances from the soil will be more rapid than when only a small amount of crop is grown1 and the soil will be sooner exhausted--not by the lime1 but by the plants4 ,in order to make up for this exhaustion1 it is necessary that a sufficient amount of inorganic matter be supplied to compensate for the increased quantity taken away by plants4 ,thus we see1 that it is hardly fair to accuse the lime of exhausting the soil1 when it only improves its character1 and increases the amount of its yield4 ,it is the crop that takes away the fertility of the soil 7the same as would be the case if no lime were used1 only faster as the crop is larger71 and in all judicious cultivation1 this loss will be fully compensated by the application of manures1 thereby preventing the exhaustion of the soil4 ,is the purchase of marl to be recommended8 ,how is lime prepared for use8 7,note47 ,describe the burning and slaking of lime4 ,kind of lime to be used4 ,the first consideration in procuring lime for manuring land1 is to select that which contains but little1 if any magnesia4 ,nearly all stone lime contains more or less of this1 but some kinds contain more than others4 ,when magnesia is applied to the soil1 in too large quantities1 it is positively injurious to plants1 and great care is necessary in making selection4 ,as a general rule1 it may be stated1 that the best plastering lime makes the best manure4 ,such kinds only should be used as are known from experiment not to be injurious4 ,shell lime is undoubtedly the best of all1 for it contains no magnesia1 and it does contain a small quantity of phosphate of lime4 ,in the vicinity of the sea-coast1 and near the lines of railroads1 oyster shells1 clam shells1 etc41 can be cheaply procured4 ,these may be prepared for use in the same manner as stone lime4,,ag ,the preparation of the lime is done by first burning and then slaking1 or by putting it directly on the land1 in an unslaked condition1 after its having been burned4 ,shells are sometimes ground1 and used without burning2 this is hardly advisable1 as they cannot be made so fine as by burning and slaking4 ,as was stated in the first section of this book1 lime usually exists in nature1 in the form of carbonate of lime1 as limestone1 chalk1 or marble 7being lime and carbonic acid combined71 and when this is burned1 the carbonic acid is thrown off1 leaving the lime in a pure or caustic form4 ,this is called burned lime1 quick-lime1 lime shells1 hot lime1 etc4 ,if the proper quantity of water be poured on it1 it is immediately taken up by the lime1 which falls into a dry powder1 called slaked lime4 ,if quick-lime were left exposed to the weather1 it would absorb moisture from the atmosphere1 and become what is termed air slaked4 ,what is air slaking8 ,if slaked lime be exposed to the air1 what change does it undergo8 ,what is the object of slaking lime8 ,how much carbonic acid is contained in a ton of carbonate of lime8 ,how much lime does a ton of slaked lime contain8 ,what is the most economical form for transportation8 ,when slaked lime 7consisting of lime and water7 is exposed to the atmosphere1 it absorbs carbonic acid1 and becomes carbonate of lime again2 but it is now in the form of a very fine powder1 and is much more useful than when in the stone4 ,if quick-lime is applied directly to the soil1 it absorbs first moisture1 and then carbonic acid1 becoming finally a powdered carbonate of lime4 ,one ton of carbonate of lime contains #aa cwt4 of lime2 the remainder is carbonic acid4 ,one ton of slaked lime contains about #ae cwt4 of lime2 the remainder is water4 ,hence we see that lime should be burned1 and not slaked1 before being transported1 as it would be unprofitable to transport the large quantity of carbonic acid and water contained in carbonate of lime and slaked lime4 ,the quick-lime may be slaked1 and carbonated after reaching its destination1 either before or after being applied to the land4 ,what is the best form for immediate action on the inorganic matter in the soil8 ,for most other purposes8 ,as has been before stated1 much is gained by slaking lime with salt water1 thus imitating the lime and salt mixture4 ,indeed in many cases1 it will be found profitable to use all lime in this way4 ,where a direct action on the inorganic matters contained in the soil is desired1 it may be well to apply the lime directly in the form of quick-lime2 but1 where the decomposition of the vegetable and animal constituents of the soil is desired1 the correction of sourness1 or the supplying of lime to the crop1 the mixture with salt would be advisable4 ,the amount of lime required by plants is1 as was before observed1 usually small compared with the whole amount contained in the soil2 still it is not unimportant4 ,,of ,,lime4 #be bus4 of wheat contain about #ac lbs4 #be barley #aj #be oats #aa #b tons of turnips #ab #b potatoes #e #b red clover #gg #b rye grass #cj ,,ah ,what is the best guide concerning the quantity of lime to be applied8 ,what is said of the sinking of lime in the soil8 ,what is plaster of ,paris composed of8 ,why is it called plaster of ,paris8 ,the amount of lime required at each application1 and the frequency of those applications1 must depend on the chemical and mechanical condition of the soil4 ,no exact rule can be given1 but probably the custom of each district--regulated by long experience--is the best guide4 ,lime sinks in the soil2 and therefore1 when used alone1 should always be applied as a top dressing to be carried into the soil by rains4 ,the tendency of lime to settle is so great that1 when cutting drains1 it may often be observed in a whitish streak on the top of the subsoil4 ,after heavy doses of lime have been given to the soil1 and have settled so as to have apparently ceased from their action1 they may be brought up and mixed with the soil by deeper plowing4 ,lime should never be mixed with animal manures1 unless in compost with muck1 or some other good absorbent1 as it is liable to cause the escape of their ammonia4 ,,plaster ,,of ,,paris4 ,plaster of ,paris or ,gypsum 7sulphate of lime7 is composed of sulphuric acid and lime in combination4 ,it is called 'plaster of ,paris1' because it constitutes the rock underlying the city of ,paris4 ,is it a constituent of plants8 ,what else does it furnish them8 ,how does it affect manure8 ,how does it produce sorrel in the soil8 ,how may the acidity be overcome8 ,it is a constituent of many plants4 ,it also furnishes them with sulphur--a constituent of the sulphuric acid which it contains4 ,it is an excellent absorbent of ammonia1 and is very useful to sprinkle around stables1 poultry houses1 pig-styes1 and privies1 where it absorbs the escaping gases1 saving them for the use of plants1 and purifying the air1 thus rendering stables1 etc41 more healthy than when not so supplied4 ,it has been observed that the extravagant use of plaster sometimes induces the growth of sorrel4 ,this is probably the case only where the soil is deficient in lime4 ,in such instances1 the lime required by plants is obtained by the decomposition of the plaster4 ,the lime enters into the construction of the plant1 and the sulphuric acid remains free1 rendering the soil sour1 and therefore in condition to produce sorrel4 ,in such a case1 an application of lime will correct the acid by uniting with it and converting it into plaster4 ,,chloride ,,of ,,lime4 ,what does chloride of lime supply to plants8 ,how does it affect manures8 ,how may it be used8 ,how may magnesia be supplied1 when wanting8 ,what care is necessary concerning the use of magnesia8 ,chloride of lime is a compound of lime and chlorine4 ,it furnishes both of these constituents to plants1 and it is an excellent absorbent of ammonia and other gases arising from decomposition--hence its usefulness in destroying bad odors1 and in preserving fertilizing matters for the use of crops4 ,it may be used like plaster1 or in the decomposition of organic matters1 where it not only hastens decay1 but absorbs and retains the escaping gases4 ,it will be recollected that chloride of lime is one of the products of the lime and salt mixture4 ,lime in combination with phosphoric acid forms the valuable phosphate of lime1 of which so large a portion of the ash of grain1 and the bones of animals1 is formed4 ,this will be spoken of more at length under the head of 'phosphoric acid4' ,,magnesia4 ,magnesia is a constituent of vegetable ashes1 and is almost always present in the soil in sufficient quantities4 ,when analysis indicates that it is needed1 it may be applied in the form of magnesian lime1 or refuse epsom salts1 which are composed of sulphuric acid and magnesia 7sulphate of magnesia74 ,the great care necessary concerning the use of magnesia is1 not to apply too much of it1 it being1 when in excess1 as has been previously remarked1 injurious to the fertility of the soil4 ,some soils are hopelessly barren from the fact that they contain too much magnesia4 ,,acids4 ,,sulphuric ,,acid4 ,what is sulphuric acid commonly called8 ,how may it be used8 ,how does it prevent the escape of ammonia8 ,sulphuric acid is a very important constituent of vegetable ashes1 especially of oats and the root-crops4 ,it is often deficient in the soil1 particularly where potatoes have been long cultivated4 ,one of the reasons why plaster 7sulphate of lime7 is so beneficial to the potato crop is undoubtedly that it supplies it with sulphuric acid4 ,sulphuric acid is commonly known by the name of oil vitriol1 and may be purchased for agricultural purposes at a low price4 ,it may be used in a very dilute form 7weakened by mixing it with a large quantity of water7 to the compost heap1 where it will change the ammonia to a sulphate as soon as formed1 and thus prevent its loss1 as the sulphate of ammonia is not volatile2 and1 being soluble in water1 is useful to plants4 ,some idea of the value of this compound may be formed from the fact that manufacturers of manures are willing to pay seven cents per lb41 or even more1 for sulphate of ammonia1 to insure the success of their fertilizers4 ,notwithstanding this1 many farmers persist in throwing away hundreds of pounds of ammonia every year1 as a tax for their ignorance 7or indolence71 while a small tax in money--not more valuable1 nor more necessary to their success--for the support of common schools1 and the better education of the young1 is too often unwillingly paid4 ,what is the effect of using too much sulphuric acid8 ,if a tumbler full of sulphuric acid 7costing a few cents71 be thrown into the tank of the compost heap once a month1 the benefit to the manure would be very great4 ,where a deficiency of sulphuric acid in the soil is indicated by analysis1 it may be supplied in this way1 or by the use of plaster or refuse epsom salts4 ,care is necessary that too much sulphuric acid be not used1 as it would prevent the proper decomposition of manures1 and would induce a growth of sorrel in the soil by making it sour4 ,in many instances1 it will be found profitable to use sulphuric acid in the manufacture of super-phosphate of lime 7as directed under the head of 'phosphoric acid1'7 thus making it perform the double purpose of preparing an available form of phosphate1 and of supplying sulphur and sulphuric acid to the plant4 ,,phosphoric ,,acid4 ,how large a part of the ashes of grain consists of phosphoric acid8 ,of what other substances does it form a leading ingredient8 ,how many pounds of sulphuric acid are contained in one hundred bushels of wheat8 ,we come now to the consideration of one of the most important of all subjects connected with agriculture1 that is1 phosphoric acid4 ,phosphoric acid1 forming about one half of the ashes of wheat1 rye1 corn1 buckwheat1 and oats2 nearly the same proportion of those of barley1 peas1 beans and linseed2 an important ingredient of the ashes of potatoes and turnips2 one quarter of the ash of milk and a large proportion of the bones of animals1 often exists in the soil in the proportion of only about one or two pounds in a thousand4 ,the cultivation of our whole country has been such1 as to take away the phosphoric acid from the soil without returning it1 except in very minute quantities4 ,every hundred bushels of wheat sold contains 7and removes permanently from the soil7 about sixty pounds of phosphoric acid4 ,other grains1 as well as the root crops and grasses1 remove likewise a large quantity of it4 ,it has been said by a contemporary writer1 that for each cow kept on a pasture through the summer1 there is carried off in veal1 butter and cheese1 not less than fifty lbs4 of phosphate of lime 7bone-earth7 on an average4 ,this would be one thousand lbs4 for twenty cows2 and it shows clearly why old dairy pastures become so exhausted of this substance1 that they will no longer produce those nutritious grasses1 which are favorable to butter and cheese-making4 ,how much phosphate of lime will twenty cows remove from a pasture during a summer8 ,what has this removal of phosphate of lime occasioned8 ,how have the ,genesee and ,mohawk valleys been affected by this removal of phosphoric acid8 ,that this removal of the most valuable constituent of the soil1 has been the cause of more exhaustion of farms1 and more emigration1 in search of fertile districts1 than any other single effect of injudicious farming1 is a fact which multiplied instances most clearly prove4 ,it is stated that the ,genesee and ,mohawk valleys1 which once produced an average of thirty-five or forty bushels of wheat1 per acre1 have since been reduced in their average production to twelve and a half bushels4 ,hundreds of similar cases might be stated2 and in a large majority of these1 could the cause of the impoverishment be ascertained1 it would be found to be the removal of the phosphoric acid from the soil4 ,how may this devastation be arrested8 ,is any soil inexhaustible8 ,what is usually the best source from which to obtain phosphoric acid8 ,the evident tendency of cultivation being to continue this murderous system1 and to prey upon the vital strength of the country1 it is necessary to take such measures as will arrest the outflow of this valuable material4 ,this can never be fully accomplished until laws shall be made preventing the wastes of cities and towns4 ,such laws have existed for a long time in ,china1 and have doubtlessly been the secret of the long subsistence and present prosperity of the millions of people inhabiting that country4 ,we have1 nevertheless1 a means of restoring to fertility many of our worn-out lands1 and preserving our fertile fields from so rapid impoverishment as they are now suffering4 ,many suppose that soils which produce good crops1 year after year1 are inexhaustible1 but time will prove to the contrary4 ,they may possess a sufficiently large stock of phosphoric acid1 and other constituents of plants1 to last a long time1 but when that stock becomes so reduced1 that there is not enough left for the uses of full crops1 the productive power of the soil will yearly decrease1 until it becomes worthless4 ,it may last a long time1 a century1 or even more1 but as long as the system is--to remove every thing1 and return nothing1--the fate of the most fertile soil is evident4 ,the source mentioned1 from which to obtain phosphoric acid1 is the bones of animals4 ,these contain large quantities of phosphate of lime4 ,they are the receptacles which collect nearly all of the phosphates in crops1 which are fed to animals1 and are not returned in their excrements4 ,for the grain1 etc41 sent out of the country1 there is no way to be repaid except by the importation of this material2 but1 all that is fed to animals1 or to human beings1 may1 if a proper use be made of their excrement1 and of their bones after death1 be returned to the soil4 ,with the treatment of animal excrements we are already familiar1 and we will now turn our attention to the subject of ,,bones4 ,of what do dried bones consist8 ,what is the organic matter of bones8 ,the inorganic8 ,what can you say of the use of whole bones8 ,bones consist1 when dried1 of about one third organic matter1 and two thirds inorganic matter4 ,the organic matter consists chiefly of gelatine--a compound containing nitrogen4 ,the inorganic part is chiefly phosphate of lime4 ,hence1 we see that bones are excellent1 as both organic and mineral manure4 ,the organic part1 containing nitrogen1 forms ammonia1 and the inorganic part supplies the much needed phosphoric acid to the soil4 ,liebig says that1 as a producer of ammonia1 #ajj lbs4 of dry bones are equivalent to #bej lbs4 of human urine4 ,how does the value of bone dust compare with that of broken bones8 ,what is the reason of the superiority of bone dust8 ,how is bone-black made8 ,of what does it consist8 ,bones are applied to the soil in almost every conceivable form4 ,whole bones are often used in very large quantities2 their action1 however1 is extremely slow1 and it is never advisable to use bones in this form4 ,ten bushels of bones1 finely ground1 will produce larger results1 during the current ten years after application1 than would ensue from the use of one hundred bushels merely broken1 not because the dust contains more fertilizing matter than the whole bones1 but because that which it does contain is in a much more available condition4 ,it ferments readily1 and produces ammonia1 while the ashy parts are exposed to the action of roots4 ,should farmers burn bones before using them8 ,how would you compost bones with ashes8 ,in what way would you prevent the escape of ammonia8 ,bone-black4 ,if bones are burned in retorts1 or otherwise protected from the atmosphere1 their organic matter will all be driven off1 except the carbon1 which not being supplied with oxygen cannot escape4 ,in this form bones are called ivory black1 or bone-black4 ,it consists of the inorganic matter1 and the carbon of the bones4 ,the nitrogen having been expelled it can make no ammonia1 and thus far the original value of bones is reduced by burning2 that is1 one ton of bones contains more fertilizing matter before1 than after burning2 but one ton of bone black is more valuable than one ton of raw bones1 as the carbon is retained in a good form to act as an absorbent in the soil1 while the whole may be crushed or ground much more easily than before being burned4 ,this means of pulverizing bones is adopted by manufacturers1 who replace the ammonia in the form of guano1 or otherwise2 but it is not to be recommended for the use of farmers1 who should not lose the ammonia1 forming a part of bones1 more than that of other manure4 ,composting bones with ashes is a good means of securing their decomposition4 ,they should be placed in a water-tight vessel 7such as a cask72 first1 three or four inches of bones1 then the same quantity of strong unleached wood ashes1 continuing these alternate layers until the cask is full1 and keeping them always wet4 ,if they become too dry they will throw off an offensive odor1 accompanied by the escape of ammonia1 and consequent loss of value4 ,in about one year1 the whole mass of bones 7except1 perhaps1 those at the top7 will be softened1 so that they may be easily crushed1 and they are in a good condition for manuring4 ,the ashes are1 in themselves1 valuable1 and this compost is excellent for many crops1 particularly for ,indian corn4 ,a little dilute sulphuric acid1 occasionally sprinkled on the upper part of the matter in the cask1 will prevent the escape of the ammonia4 ,what is the effect of boiling bones under pressure8 ,how is super-phosphate of lime made8 ,describe the composition of phosphate of lime1 and the chemical changes which take place in altering it to super-phosphate of lime4 ,boiling bones under pressure1 whereby their gelatine is dissolved away1 and the inorganic matter left in an available condition1 from its softness1 is a very good way of rendering them useful2 but1 as it requires1 among other things1 a steam boiler1 it is hardly probable that it will be largely adopted by farmers of limited means4 ,any or all of these methods are good1 but bones cannot be used with true economy1 except by changing their inorganic matter into ,,super-,,phosphate ,,of ,,lime4 ,super-phosphate of lime is made by treating phosphate of lime1 or the ashes of bones1 with sulphuric acid4 ,phosphate of lime1 as it exists in bones1 consists of one atom of phosphoric acid and three atoms of lime4 ,it may be represented as ,lime ,phosphoric acid ,lime ,lime ,by adding a proper quantity of sulphuric acid with this1 it becomes super-phosphate of lime2 that is1 the same amount of phosphoric acid1 with a smaller proportion of lime 7or a super-abundance of phosphoric acid71 the sulphuric acid1 taking two atoms of lime away from the compound1 combined with it making sulphate of lime 7plaster74 ,the changes may be thus represented4 ,phosphoric acid ,super-phosphate ,phosphate of lime ,lime of lime4 ,lime ,lime ,sulphate of lime4 ,sulphuric acid ,super-phosphate of lime may be made from whole bones1 bone dust1 bone-black1 or from the pure ashes of bones4 ,how should sulphuric acid be applied to whole bones8 ,what is the necessity for so large an amount of water8 ,the process of making it from whole bones is slow and troublesome1 as it requires a long time for the effect to diffuse itself through the whole mass of a large bone4 ,when it is made in this way1 the bones should be dry1 and the acid should be diluted in many times its bulk of water1 and should be applied to the bones 7which may be placed in a suitable cask1 with a spiggot at the bottom71 in quantities sufficient to cover them1 about once in ten days2 and at the end of that time1 one half of the liquid should be drawn off by the spiggot4 ,this liquid is a solution of super-phosphate of lime1 containing sulphate of lime1 and may be applied to the soil in a liquid form1 or through the medium of a compost heap4 ,the object of using so much water is to prevent an incrustation of sulphate of lime on the surfaces of the bones1 this must be removed by stirring the mass1 which allows the next application of acid to act directly on the phosphate remaining4 ,the amount of acid required is about #ej or #fj lbs4 to each #ajj lbs4 of bones4 ,the gelatine will remain after the phosphate is all dissolved1 and may be composted with muck1 or plowed under the soil1 where it will form ammonia4 ,may less water be employed in making super-phosphate from bone dust or crushed bones8 ,bone dust1 or crushed bones1 may be much more easily changed to the desired condition1 as the surface exposed is much greater1 and the acid can act more generally throughout the whole mass4 ,the amount of acid required is the same as in the other case1 but it may be used stronger1 two or three times its bulk of water being sufficient1 if the bones are finely ground or crushed--more or less water should be used according to the fineness of the bones4 ,the time occupied will also be much less1 and the result of the operation will be in better condition for manure4 ,bones may be made fine enough for this operation1 either by grinding1 etc41 or by boiling under pressure1 as previously described2 indeed1 by whatever method bones are pulverized1 they should always be treated with sulphuric acid before being applied to the soil1 as this will more than double their value for immediate use4 ,bone-black is chiefly used by manufacturers of super-phosphate of lime1 who treat it with acid the same as has been directed above1 only that they grind the black very finely before applying the acid4 ,what other forms of bones may be used in making super-phosphate of lime8 ,why is super-phosphate of lime a better fertilizer than phosphate of lime8 ,what can you say of the lasting manures8 ,bone ashes1 or bones burned to whiteness1 may be similarly treated4 ,indeed1 in all of the forms of bones here described1 the phosphate of lime remains unaltered1 as it is indestructible by heat2 the differences of composition are only in the admixture of organic constituents4 ,the reason why super-phosphate of lime is so much better than phosphate1 may be easily explained4 ,the phosphate is very slowly soluble in water1 and consequently furnishes food to plants slowly4 ,a piece of bone as large as a pea may lie in the soil for years without being all consumed2 consequently1 it will be years before its value is returned1 and it pays no interest on its cost while lying there4 ,the super-phosphate dissolves very rapidly and furnishes food for plants with equal facility2 hence its much greater value as a manure4 ,it is true that the phosphate is the most lasting manure2 but1 once for all1 let us caution farmers against considering this a virtue in mineral manures1 or in organic manures either1 when used on soils containing the proper absorbents of ammonia4 ,they are lasting1 only in proportion as they are lazy4 ,manures are worthless unless they are in condition to be immediately used4 ,the farmer who wishes his manures to last in the soil1 and to lose their use1 may be justly compared with the miser1 who buries his gold and silver in the ground for the satisfaction of knowing that he owns it4 ,it is an old and a true saying that a nimble sixpence is better than a slow shilling4 ,,improved ,,super-,,phosphate ,,of ,,lime4 ,what are the ingredients of the improved super-phosphate of lime8 ,to show the manner in which super-phosphate of lime is perfected1 and rendered the best manure for general uses1 which has yet been made1 containing large quantities of phosphoric acid and a good supply of ammonia1--hereby covering the two leading deficiencies in a majority of soils1 it may be well to explain the composition of the improved super-phosphate of lime invented by ,prof4 ,mapes4 ,this manure consists of the following ingredients in the proportions named3-- #ajj lbs4 bone-black 7phosphate of lime and carbon74 #ef sulphuric acid4 #cf guano4 #bj sulphate of ammonia4 ,explain the uses of these different constituents4 ,what is nitrogenized phosphate8 ,the sulphuric acid has the before-mentioned effect on the bone-black1 and fixes the ammonia of the guano by changing it to a sulphate4 ,the twenty pounds of sulphate of ammonia added increase the amount1 so as to furnish nitrogen to plants in sufficient quantities to give them energy1 and induce them to take up the super-phosphate of lime in the manure more readily than would be done1 were there not a sufficient supply of ammonia in the soil4 ,the addition of the guano1 which contains all of the elements of fertility1 and many of them in considerable quantities1 renders the manure of a more general character1 and enables it to produce very large crops of almost any kind1 while it assists in fortifying the soil in what is usually its weakest point--phosphoric acid4 ,prof4 ,mapes has more recently invented a new fertilizer called nitrogenized super-phosphate of lime1 composed of the improved super-phosphate of lime and blood1 dried and ground before mixture1 in equal proportions4 ,this manure1 from its highly nitrogenous character1 theoretically surpasses all others1 and probably will be found in practice to have great value2 its cost will be rather greater than guano4 ,we understand its manufacture will shortly be commenced by a company now forming for that purpose4 ,what should be learned before purchasing amendments for the soil8 ,what do you know of silica8 ,many farmers will find it expedient to purchase bones1 or bone dust1 and manufacture their own super-phosphate of lime2 others will prefer to purchase the prepared manure4 ,in doing so1 it should be obtained of men of known respectability1 as manures are easily adulterated with worthless matters2 and1 as their price is so high1 that such deception may occasion great loss4 ,we would not recommend the application of any artificial manure1 without first obtaining an analysis of the soil1 and knowing to a certainty that the manure is needed2 still1 when no analysis has been procured1 it may be profitable to apply such manures as most generally produce good results--such as stable manure1 night soil1 the improved super-phosphate of lime2 or1 if this cannot be procured1 guano4 ,,neutrals4 ,,silica4 ,silica 7or sand7 always exists in the soil in sufficient quantities for the supply of food for plants2 but1 as has been often stated in the preceding pages1 not always in the proper condition4 ,this subject has been so often explained to the student of this book1 that it is only necessary to repeat here1 that when the weakness of the straw or stalk of plants grown on any soil indicates an inability in that soil to supply the silicates required for strength1 not more sand should be added1 but alkalies1 to combine with the sand already contained in it1 and make soluble silicates which are available to roots4 ,sand is often necessary to stiff clays1 as a mechanical manure1 to loosen their texture and render them easier of cultivation1 and more favorable to the distribution of roots1 and to the circulation of air and water4 ,,chlorine4 ,how may chlorine be applied8 ,chlorine1 a necessary constituent of plants1 and often deficient in the soil 7as indicated by analysis71 may be applied in the form of salt 7chloride of sodium71 or chloride of lime4 ,the former may be dissolved in the water used to slake lime1 and the latter may1 with much advantage1 be sprinkled around stables and other places where fertilizing gases are escaping1 and1 after being saturated with ammonia1 applied to the soil1 thus serving a double purpose4 ,,oxide ,,of ,,iron4 ,how may the protoxide of iron be changed to peroxide8 ,nearly all soils contain sufficient quantities of oxide of iron1 or iron rust1 so that this substance can hardly be required as a manure4 ,some soils1 however1 contain the protoxide of iron in such quantities as to be injurious to plants1--see page #hf4 ,when this is the case1 it is necessary to plow the soil thoroughly1 and use such other mechanical means as shall render it open to the admission of air4 ,the protoxide of iron will then take up more oxygen1 and become the peroxide--which is not only inoffensive1 but is absolutely necessary to fertility4 ,,oxide ,,of ,,manganese4 ,this can hardly be called an essential constituent of plants1 and is never taken into consideration in manuring lands4 ,,various ,,other ,,mineral ,,manures4 ,,leached ,,ashes4 ,why are leached ashes inferior to those that have not been leached8 ,on what do the benefits of leached ashes depend8 ,can these ingredients be more cheaply obtained in another form8 ,why do unleached ashes1 applied in the spring1 sometimes cause grain to lodge8 ,among the mineral manures which have not yet been mentioned--not coming strictly under any of the preceding heads1 is the one known as leached ashes4 ,these are not without their benefits1 though worth much less than unleached ashes1 which1 besides the constituents of those which have been leached1 contain much potash1 soda1 etc4 ,farmers have generally overrated the value of leached ashes1 because they contain small quantities of available phosphate of lime1 and soluble silicates1 in which most old soils are deficient4 ,while we witness the good results ensuing from their application1 we should not forget that the fertilizing ingredients of thirty bushels of these ashes may be bought in a more convenient form for ten or fifteen cents1 or for less than the cost of spreading the ashes on the soil4 ,in many parts of ,long ,island farmers pay as much as eight or ten cents per bushel for this manure1 and thousands of loads of leached ashes are taken to this locality from the river counties of ,new ,york1 and even from the ,state of ,maine1 and are sold for many times their value1 producing an effect which could be as well and much more cheaply obtained by the use of small quantities of super-phosphate of lime and potash4 ,these ashes often contain a little charcoal 7resulting from the imperfect combustion of the wood71 which acts as an absorbent of ammonia4 ,it is sometimes observed that unleached ashes1 when applied in the spring1 cause grain to lodge4 ,when this is the case1 as it seldom is1 it may be inferred that the potash which they contain causes so rapid a growth1 that the soil is not able to supply silicates as fast as they are required by the plants1 but after the first year1 the potash will have united with the silica in the soil1 and overcome the difficulty4 ,,old ,,mortar4 ,what are the most fertilizing ingredients of old mortar8 ,old mortar is a valuable manure1 because it contains nitrate of potash and other compounds of nitric acid with alkalies4 ,these are slowly formed in the mortar by the changing of the nitrogen of the hair 7in the mortar7 into nitric acid1 and the union of this with the small quantities of potash1 or with the lime of the plaster4 ,nitrogen1 presented in other forms1 as ammonia1 for instance1 may be transformed into nitric acid1 by uniting with the oxygen of the air1 and this nitric acid combines immediately with the alkalies of the mortar4,,ai ,the lime contained in the mortar may be useful in the soil for the many purposes accomplished by other lime4 ,,gas ,,house ,,lime4 ,how may gas-house lime be prepared for use8 ,why should it not be used fresh1 from the gas house8 ,on what do its fertilizing properties depend8 ,what use may be made of its offensive odor8 ,the refuse lime of gas works1 where it can be cheaply obtained1 may be advantageously used as a manure4 ,it consists1 chiefly1 of various compounds of sulphur and lime4 ,it should be composted with earth or refuse matter1 so as to expose it to the action of air4 ,it should never be used fresh from the gas house4 ,in a few months the sulphur will have united with the oxygen of the air1 and become sulphuric acid1 which unites with the lime and makes sulphate of lime 7plaster71 which form it must assume1 before it is of much value4 ,having been used to purify gas made from coal1 it contains a small quantity of ammonia1 which adds to its value4 ,it is considered a profitable manure in ,england1 at the price there paid for it 7forty cents a cartload71 and1 if of good quality1 it may be worth double that sum1 especially for soils deficient in plaster1 or for such crops as are much benefited by plaster4 ,its price must1 of course1 be regulated somewhat by the price of lime1 which constitutes a large proportion of its fertilizing parts4 ,the offensive odor of this compound renders it a good protection against many insects4 ,the refuse liquor of gas works contains enough ammonia to make it a valuable manure4 ,,soapers' ,,ley ,,and ,,bleachers' ,,ley4 ,what use may be made of the refuse ley of soap-makers and bleachers8 ,what peculiar qualities does soapers' ley possess8 ,the refuse ley of soap factories and bleaching establishments contains greater or less quantities of soluble silicates and alkalies 7especially soda and potash71 and is a good addition to the tank of the compost heap1 or it may be used directly as a liquid application to the soil4 ,the soapers' ley1 especially1 will be found a good manure for lands on which grain lodges4 ,much of the benefit of this manure arises from the soluble silicates it contains1 while its nitrogenous matter1,,aj obtained from those parts of the fatty matters which cannot be converted into soap1 and consequently remains in this solution1 forms a valuable addition4 ,heaps of soil saturated with this liquid in autumn1 and subjected to the freezings of winter1 form an admirable manure for spring use4 ,mr4 ,crane1 near ,newark 7,n4 ,j471 has long used a mixture of spent ley and stable manure1 applied in the fall to trenches plowed in the soil1 and has been most successful in obtaining large crops4 ,,irrigation4 ,on what does the benefit arising from irrigation chiefly depend8 ,what kind of water is best for irrigation8 ,how do under-drains increase the benefits of irrigation8 ,irrigation does not come strictly under the head of inorganic manures1 as it often supplies ammonia to the soil4 ,its chief value1 however1 in most cases1 must depend on the amount of mineral matter which it furnishes4 ,the word irrigation means simply watering4 ,in many districts water is in various ways made to overflow the land1 and is removed when necessary for the purposes of cultivation4 ,all river and spring water contains some impurities1 many of which are beneficial to vegetation4 ,these are derived from the earth over1 or through which1 the water has passed1 and ammonia absorbed from the atmosphere4 ,when water is made to cover the earth1 especially if its rapid motion be arrested1 much of this fertilizing matter settles1 and is deposited on the soil4 ,the water which sinks into the soil carries its impurities to be retained for the uses of plants4 ,when1 by the aid of under-drains1 or in open soils1 the water passes through the soil1 its impurities are arrested1 and become available in vegetable growth4 ,it is1 of course1 impossible to say exactly what kind of mineral matter is supplied by water1 as that depends on the kind of rock or soil from which the impurities are derived2 but1 whatever it may be1 it is generally soluble and ready for immediate use by plants4 ,what is the difference between water which only runs over the surface of the earth1 and that which runs out of the earth8 ,why should strong currents of water not be allowed to traverse the soil8 ,water which has run over the surface of the earth contains both ammonia and mineral matter1 while that which has arisen out of the earth1 contains usually only mineral matter4 ,the direct use of the water of irrigation as a solvent for the mineral ingredients of the soil1 is one of its main benefits4 ,to describe the many modes of irrigation would be too long a task for our limited space4 ,it may be applied in any way in which it is possible to cover the land with water1 at stated times4 ,care is necessary1 however1 that it do not wash more fertilizing matter from the soil than it deposits on it1 as would often be the case1 if a strong current of water were run over it4 ,brooks may be dammed up1 and thus made to cover a large quantity of land4 ,in such a case the rapid current would be destroyed1 and the fertilizing matter would settle2 but1 if the course of the brook were turned1 so that it would run in a current over any part of the soil1 it might carry away more than it deposited1 and thus prove injurious4 ,small streams turned on to land1 from the washing of roads1 or from elevated springs1 are good means of irrigation1 and produce increased fertility1 except where the soil is of such a character as to prevent the water from passing away1 in which case it should be under-drained4 ,irrigation was one of the oldest means of fertility ever used by man1 and still continues in great favor wherever its effects have been witnessed4 ,,mixing ,,soils4 ,how are soils improved by mixing8 ,the mixing of soils is often all that is necessary to render them fertile1 and to improve their mechanical condition4 ,for instance1 soils deficient in potash1 or any other constituent1 may have that deficiency supplied1 by mixing with them soil containing this constituent in excess4 ,it is very frequently the case1 that such means of improvement are easily availed of4 ,while these chemical effects are being produced1 there may be an equal improvement in the mechanical character of the soil4 ,thus stiff clay soils are rendered lighter1 and more easily workable1 by an admixture of sand1 while light blowy sands are compacted1 and made more retentive of manure1 by a dressing of clay or of muck4 ,why may the same effect sometimes be produced by deep plowing8 ,what is absolutely necessary to economical manuring8 ,of course1 this cannot be depended on as a sure means of chemical improvement1 unless the soils are previously analyzed1 so as to know their requirements2 but1 in a majority of cases1 the soil will be benefited1 by mixing with it soil of a different character4 ,it is not always necessary to go to other locations to procure the soil to be applied1 as the subsoil is often very different from the surface soil1 and simple deep plowing will suffice1 in such cases1 to produce the required admixture1 by bringing up the earth from below to mingle it with that of a different character at the surface4 99 99 99 99 99 ,in the foregoing remarks on the subject of mineral manures1 the writer has endeavored to point out such a course as would produce the greatest good to the greatest number1 and1 consequently1 has neglected much which might discourage the farmer with the idea1 that the whole system of scientific agriculture is too expensive for his adoption4 ,still1 while he has confined his remarks to the more simple improvements on the present system of management1 he would say1 briefly1 that no manuring can be strictly economical that is not based on an analysis of the soil1 and a knowledge of the best means of overcoming the deficiencies indicated1 together with the most scrupulous care of every ounce of evaporating or soluble manure4 ,,footnotes3 ,,ag ,marl is earth containing lime1 but its use is not to be recommended in this country1 except where it can be obtained at little cost1 as the expenses of carting the earth would often be more than the value of the lime4 ,,ah ,the straw producing the grain and the turnip and potato tops contain more lime than the grain and roots4 ,,ai ,see ,working ,farmer1 vol4 #b1 p4 #bgh4 ,,aj ,glycerine1 etc4 ,,chapter ,x4 ,,atmospheric ,,fertilizers4 ,are the gases in the atmosphere manures8 ,what would be the result if they were not so8 ,it is not common to look on the gases in the atmosphere in the light of manures1 but they are decidedly so4 ,indeed1 they are almost the only organic manure ever received by the uncultivated parts of the earth1 as well as a large portion of that which is occupied in the production of food for man4 ,if these gases were not manures2 if there were no means by which they could be used by plants1 the fertility of the soil would long since have ceased1 and the earth would now be in an unfertile condition4 ,that this must be true1 will be proved by a few moments' reflection on the facts stated in the first part of this book4 ,the fertilizing gases in the atmosphere being composed of the constituents of decayed plants and animals1 it is as necessary that they should be again returned to the form of organized matter1 as it is that constituents taken from the soil should not be put out of existence4 ,,ammonia4 ,how is ammonia used by plants8 ,how may it be carried to the soil8 ,how may the value of organic manures be estimated8 ,what effects has ammonia beside supplying food to plants8 ,the ammonia in the atmosphere probably cannot be appropriated by the leaves of plants1 and must1 therefore1 enter the soil to be assimilated by roots4 ,it reaches the soil in two ways4 ,it is either arrested from the air circulating through the soil1 or it is absorbed by rains in the atmosphere1 and thus carried to the earth1 where it is retained by clay and carbon1 for the uses of plants4 ,in the soil1 ammonia is the most important of all organic manures4 ,in fact1 the value of organic manure may be estimated1 either by the amount of ammonia which it will yield1 or by its power of absorbing ammonia from other sources4 ,the most important action of ammonia in the soil is the supply of nitrogen to plants2 but it has other offices which are of consequence4 ,it assists in some of the chemical changes necessary to prepare the matters in the soil for assimilation4 ,some argue that ammonia stimulates the roots of plants1 and causes them to take up increased quantities of inorganic matter4 ,the discussion of this question would be out of place here1 and we will simply say1 that it gives them such vigor that they require increased amounts of ashy matter1 and enables them to take this from the soil4 ,to how great a degree can the farmer control atmospheric fertilizers8 ,what should be the condition of the soil8 ,what substances are good absorbents in the soil8 ,how may sandy soils be made retentive of ammonia8 ,although1 in the course of nature1 the atmospheric fertilizers are plentifully supplied to the soil1 without the immediate attention of the farmer1 it is not beyond his power to manage them in such a manner as to arrest a greater quantity4 ,the precautions necessary have been repeatedly given in the preceding pages1 but it may be well to name them again in this chapter4 ,the condition of the soil is the main point to be considered4 ,it must be such as to absorb and retain ammonia--to allow water to pass through it1 and be discharged below the point to which the roots of crops are searching for food--and to admit of a free circulation of air4 ,the power of absorbing and retaining ammonia is not possessed by sand1 but it is a prominent property of clay1 charcoal1 and some other matters named as absorbents4 ,hence1 if the soil consists of nearly pure sand1 it will not make use of the ammonia brought to it from the atmosphere1 but will allow it to evaporate immediately after a shower4 ,soils in this condition require additions of absorbent matters1 to enable them to use the ammonia received from the atmosphere4 ,soils already containing a sufficient amount of clay or charcoal1 are thus far prepared to receive benefit from this source4 ,why does under-draining increase the absorptive power of the soil8 ,how do plants obtain their carbonic acid8 ,how does carbonic acid affect caustic lime in the soil8 ,the next point is to cause the water of rains to pass through the soil4 ,if it lies on the surface1 or runs off without entering the soil1 or even if it only enters to a slight depth1 and comes in contact with but a small quantity of the absorbents1 it is not probable that the fertilizing matters which it contains will all be abstracted4 ,some of them will undoubtedly return to the atmosphere on the evaporation of the water2 but1 if the soil contains a sufficient supply of absorbents1 and will allow all rain water to pass through it1 the fertilizing gases will all be retained4 ,they will be filtered 7or raked7 out of the water4 ,this subject will be more fully treated in ,section ,,iv4 in connection with under-draining4 ,besides the properties just described1 the soil must possess the power of admitting a free circulation of air4 ,to effect this1 it is necessary that the soil should be well pulverized to a great depth4 ,if1 in addition to this1 the soil be such as to admit water to pass through1 it will allow that circulation of air necessary to the greatest supply of ammonia4 ,,carbonic ,,acid4 ,what power does it give to water8 ,what condition of the soil is necessary for the reception of the largest quantity of carbonic acid8 ,may oxygen be considered a manure8 ,what is the effect of the oxidation of the constituents of the soil8 ,carbonic acid is received from the atmosphere1 both by the leaves and roots of plants4 ,if there is caustic lime in the soil1 it unites with it1 and makes it milder and finer4 ,it is absorbed by the water in the soil1 and gives it the power of dissolving many more substances than it would do without the carbonic acid4 ,this use is one of very great importance1 as it is equivalent to making the minerals themselves more soluble4 ,water dissolves carbonate of lime1 etc41 exactly in proportion to the amount of carbonic acid which it contains4 ,we should1 therefore1 strive to have as much carbonic acid as possible in the water in the soil2 and one way1 in which to effect this1 is to admit to the soil the largest possible quantity of atmospheric air which contains this gas4 ,the condition of soil necessary for this1 is the same as is required for the deposit of ammonia by the same circulation of air4 ,,oxygen4 ,how does it affect the protoxide of iron8 ,how does it neutralize the acids in the soil8 ,how does it affect its organic parts8 ,how does it form nitric acid8 ,how may it affect excrementitious matter of plants8 ,what effect has it on the mechanical condition of the soil8 ,oxygen1 though not taken up by plants in its pure form1 may justly be classed among manures1 if we consider its effects both chemical and mechanical in the soil4 #a4 ,by oxidizing or rusting some of the constituents of the soil1 it prepares them for the uses of plants4 #b4 ,it unites with the protoxide of iron1 and changes it to the peroxide4 #c4 ,if there are acids in the soil1 which make it sour and unfertile1 it may be opened to the circulation of the air1 and the oxygen will prepare some of the mineral matters contained in the soil to unite with the acids and neutralize them4 #d4 ,oxygen combines with the carbon of organic matters in the soil1 and causes them to decay4 ,the combination produces carbonic acid4 #e4 ,it combines with the nitrogen of decaying substances and forms nitric acid1 which is serviceable as food for plants4 #f4 ,it undoubtedly affects in some way the matter which is thrown out from the roots of plants4 ,this1 if allowed to accumulate1 and remain unchanged1 is often very injurious to plants2 but1 probably1 the oxygen and carbonic acid of the air in the soil change it to a form to be inoffensive1 or even make it again useful to the plant4 #g4 ,it may also improve the mechanical condition of the soil1 as it causes its particles to crumble1 thus making it finer2 and it roughens the surfaces of particles1 making them less easy to move among each other4 ,these properties of oxygen claim for it a high place among the atmospheric fertilizers4 ,,water4 ,why may water be considered an atmospheric manure8 ,what classes of action have manures8 ,what are chemical manures8 ,mechanical8 ,water may be considered an atmospheric manure1 as its chief supply to vegetation is received from the air in the form of rain or dew4 ,its many effects are already too well known to need farther comment4 ,the means of supplying water to the soil by the deposit of dew will be fully explained in ,section ,,iv4 ,,chapter ,,xi4 ,,recapitulation4 ,manures have two distinct classes of action in the soil1 namely1 chemical and mechanical4 ,chemical manures are those which enter into the construction of plants1 or produce such chemical effects on matters in the soil as shall prepare them for use4 ,mechanical manures are those which improve the mechanical condition of the soil1 such as loosening stiff clays1 compacting light sands1 pulverizing large particles1 etc4 ,what are the three kinds of manures8 ,what are organic manures1 and what are their uses8 ,mineral8 ,atmospheric8 ,manures are of three distinct kinds1 namely1 ,organic1 mineral1 and atmospheric4 ,organic manures comprise all vegetable and animal matters 7except ashes7 which are used to fertilize the soil4 ,vegetable manures supply carbonic acid1 and inorganic matter to plants4 ,animal manures supply the same substances and ammonia4 ,mineral manures comprise ashes1 salt1 phosphate of lime1 plaster1 etc4 ,they supply plants with inorganic matter4 ,their usefulness depends on their solubility4 ,many of the organic and mineral manures have the power of absorbing ammonia arising from the decomposition of animal manures1 as well as that which is brought to the soil by rains--these are called absorbents4 ,atmospheric manures consist of ammonia1 carbonic acid1 oxygen and water4 ,their greatest usefulness requires the soil to allow the water of rains to pass through it1 to admit of a free circulation of air among its particles1 and to contain a sufficient amount of absorbent matter to arrest and retain all ammonia and carbonic acid presented to it4 ,what rule should regulate the application of manures8 ,how must organic manures be managed8 ,atmospheric8 ,manures should never be applied to the soil without regard to its requirements4 ,ammonia and carbon are almost always useful1 but mineral manures become mere dirt when applied to soils not deficient of them4 ,the only true guide to the exact requirements of the soil is chemical analysis2 and this must always be obtained before farming can be carried on with true economy4 ,organic manures must be protected against the escape of their ammonia and the leaching out of their soluble parts4 ,one cord of stable manure properly preserved1 is worth ten cords which have lost all of their ammonia by evaporation1 and their soluble parts by leaching--as is the case with much of the manure kept exposed in open barn-yards4 ,atmospheric manures cost nothing1 and are of great value when properly employed4 ,in consequence of this1 the soil which is enabled to make the largest appropriation of the atmospheric fertilizers1 is worth many times as much as that which allows them to escape4 ,,section ,,fourth4 ,,mechanical ,,cultivation4 ,,chapter ,i4 ,,the ,,mechanical ,,character ,,of ,,soils4 ,what is the first office of the soil8 ,how does it hold water for the uses of the plant8 ,how does it obtain a part of its moisture8 ,the mechanical character of the soil is well understood from preceding remarks1 and the learner knows that there are many offices to be performed by the soil aside from the feeding of plants4 #a4 ,it admits the roots of plants1 and holds them in their position4 #b4 ,by a sponge-like action1 it holds water for the uses of the plant4 #c4 ,it absorbs moisture from the atmosphere to supply the demands of plants4 ,how may it obtain heat8 ,what is the use of the air circulating among its particles8 ,could most soils be brought to the highest state of fertility8 ,what is the first thing to be done8 ,should its color be darkened8 #d4 ,it absorbs heat from the sun's rays to assist in the process of growth4 #e4 ,it admits air to circulate among roots1 and supply them with a part of their food1 while the oxygen of that air renders available the minerals of the soil2 and its carbonic acid1 being absorbed by the water in the soil1 gives it the power of dissolving1 and carrying into roots more inorganic matter than would be contained in purer water4 #f4 ,it allows the excrementitious matter thrown out by roots to be carried out of their reach4 ,all of these actions the soil must be capable of performing1 before it can be in its highest state of fertility4 ,there are comparatively few soils now in this condition1 but there are also few which could not be profitably rendered so1 by a judicious application of the modes of cultivation to be described in the following chapters4 ,the three great objects to be accomplished are3-- #a4 ,to adopt such a system of drainage as will cause all of the water of rains to pass through the soil1 instead of evaporating from the surface4 #b4 ,to pulverize the soil to a considerable depth4 #c4 ,to darken its color1 and render it capable of absorbing atmospheric fertilizers4 ,name some of the means used to secure these effects4 ,why are under-drains superior to open drains8 ,the means used to secure these effects are under-draining1 sub-soil and surface-plowing1 digging1 applying muck1 etc4 ,,chapter ,,ii4 ,,under-,,draining4 ,the advantages of under-drains over open drains are very great4 ,when open drains are used1 much water passes into them immediately from the surface1 and carries with it fertilizing parts of the soil1 while their beds are often compacted by the running water and the heat of the sun1 so that they become water-tight1 and do not admit water from the lower parts of the soil4 ,the sides of these drains are often covered with weeds1 which spread their seeds throughout the whole field4 ,open drains are not only a great obstruction to the proper cultivation of the land1 but they cause much waste of room1 as we can rarely plow nearer than within six or eight feet of them4 ,there are none of these objections to the use of under-drains1 as these are completely covered1 and do not at all interfere with the cultivation of the surface4 ,with what materials may under-drains be constructed8 ,describe the tile4 ,under drains may be made with brush1 stones1 or tiles4 ,brush is a very poor material1 and its use is hardly to be recommended4 ,small stones are better1 and if these be placed in the bottoms of the trenches1 to a depth of eight or ten inches1 and covered with sods turned upside down1 having the earth packed well down on to them1 they make very good drains4 ,,tile ,,draining4 ,the best under-drains are those made with tiles1 or burnt clay pipes4 ,the first form of these used was that called the horse-shoe tile1 which was in two distinct pieces2 this was superseded by a round pipe1 and we have now what is called the sole tile1 which is much better than either of the others4 ,illustration3 ,fig4 #d--,sole ,tile4 ,why is the sole tile superior to those of previous construction8 ,how are these tiles laid8 ,how may the trenches be dug8 ,this tile is made 7like the horse-shoe and pipe tile7 of common brick clay1 and is burned the same as bricks4 ,it is about one half or three quarters of an inch thick1 and is so porous that water passes directly through it4 ,it has a flat bottom on which to stand1 and this enables it to retain its position1 while making the drain1 better than would be done by the round pipe4 ,the orifice through which the water passes is egg-shaped1 having its smallest curve at the bottom4 ,this shape is the one most easily kept clear1 as any particles of dirt which get into the drain must fall immediately to the point where even the smallest stream of water runs1 and are thus removed4 ,an orifice of about two inches is sufficient for the smaller drains1 while the main drains require larger tiles4 ,these tiles are laid1 so that their ends will touch each other1 on the bottoms of the trenches1 and are kept in position by having the earth tightly packed around them4 ,care must be taken that no space is left between the ends of the tiles1 as dirt would be liable to get in and choke the drain4 ,it is advisable to place a sod--grass side down--over each joint1 before filling the trench1 as this more effectually protects them against the entrance of dirt4 ,there is no danger of keeping the water out by this operation1 as it will readily pass through any part of the tiles4 ,in digging the trenches it is not necessary 7except in very stony ground7 to dig out a place wide enough for a man to stand in1 as there are tools made expressly for the purpose1 by which a trench may be dug six or seven inches wide1 and to any required depth4 ,one set of these implements consists of a long narrow spade and a hoe to correspond1 such as are represented in the accompanying figure4 ,illustration3 ,fig4 #e4 ,upton tool4 ,spade and hoe4 ,with these tools1 and a long light crowbar1 for hard soils1 trenches may be dug much more cheaply than with the common spade and pickaxe4 ,where there are large boulders in the soil1 these draining tools may dig under them so that they will not have to be removed4 ,when the trenches are dug to a sufficient depth1 the bottoms must be made perfectly smooth1 with the required descent 7from six inches to a few feet in one hundred feet74 ,then the tiles may be laid in1 so that their ends will correspond1 be packed down1 and the trenches filled up4 ,such a drain1 if properly constructed1 may last for ages4 ,unlike the stone drain1 it is not liable to be frequented by rats1 nor choked up by the soil working into it4 ,the position of the tile may be best represented by a figure1 also the mode of constructing stone drains4 ,why are small stones better than large stones in the construction of drains8 ,on what must the depth of under-drains depend8 ,it will be seen that the tile drain is made with much less labor than the stone drain1 as it requires less digging1 while the breaking up of the stone for the stone drain will be nearly1 or quite as expensive as the tiles4 ,drains made with large stones are not nearly so good as with small ones1 because they are more liable to be choked up by animals working in them4,,ak ,illustration3 ,fig4 #f4 a--,tile drain trench4 b--,stone drain trench4 c--,sod laid on the stone4 ,describe the principle which regulates these relative depths and distances4 7,blackboard47 ,which is usually the cheaper plan of constructing drains8 ,the depth of the drains must depend on the distances at which they are placed4 ,if but twenty feet apart1 they need be but three feet deep2 while1 if they are eighty feet apart1 they must be five feet deep1 to produce the same effect4 ,the reason for this is1 that the water in the drained soil is not level1 but is higher midway between the drains1 than at any other point4 ,it is necessary that this highest point should be sufficiently far from the surface not to interfere with the roots of plants1 consequently1 as the water line between two drains is curved1 the most distant drains must be the deepest4 ,this will be understood by referring to the following diagram4 ,illustration3 ,fig4 #g4 aa--#e feet drains1 #hj ft4 apart4 bb--#c feet drains1 #bj ft4 apart4 ,the curved line represents the position of the water4 ,in most soils it will be easier to dig one trench five feet deep1 than four trenches three feet deep1 and the deep trenches will be equally beneficial2 but where the soil is very hard below a depth of three feet1 the shallow trenches will be the cheapest1 and in such soils they will often be better1 as the hard mass might not allow the water to pass down to enter the deeper drains4 ,by following out these instructions1 land may be cheaply1 thoroughly1 and permanently drained4 ,,footnotes3 ,,ak ,it is probable that a composition of hydraulic cement and some soluble material will be invented1 by which a continuous pipe may be laid in the bottoms of trenches1 becoming porous as the soluble material is removed by water4 ,,chapter ,,iii4 ,,advantages ,,of ,,under-,,draining4 ,the advantages of under-draining are many and important4 #a4 ,it entirely prevents drought4 #b4 ,it furnishes an increased supply of atmospheric fertilizers4 #c4 ,it warms the lower portions of the soil4 #d4 ,it hastens the decomposition of roots and other organic matter4 #e4 ,it accelerates the disintegration of the mineral matters in the soil4 #f4 ,it causes a more even distribution of nutritious matters among those parts of soil traversed by roots4

us to work sooner after rains4 #ad4 ,it keeps off the effects of cold weather longer in the fall4 #ae4 ,it prevents the formation of acetic and other organic acids1 which induce the growth of sorrel and similar weeds4 #af4 ,it hastens the decay of vegetable matter1 and the finer comminution of the earthy parts of the soil4 #ag4 ,it prevents1 in a great measure1 the evaporation of water1 and the consequent abstraction of heat from the soil4 #ah4 ,it admits fresh quantities of water from rains1 etc41 which are always more or less imbued with the fertilizing gases of the atmosphere1 to be deposited among the absorbent parts of soil1 and given up to the necessities of plants4 #ai4 ,it prevents the formation of so hard a crust on the surface of the soil as is customary on heavy lands4 99 99 99 99 99 ,how does under-draining prevent drought8 #a4 ,under-draining prevents drought1 because it gives a better circulation of air in the soil2 7it does so by making it more open74 ,there is always the same amount of water in and about the surface of the earth4 ,in winter1 there is more in the soil than in summer1 while in summer1 that which has been dried out of the soil exists in the atmosphere in the form of a vapor4 ,it is held in the vapory form by heat1 which acts as braces to keep it distended4 ,when vapor comes in contact with substances sufficiently colder than itself1 it gives up its heat--thus losing its braces--contracts1 and becomes liquid water4 ,this may be observed in hundreds of common operations4 ,why is there less water in the soil in summer than in winter1 and where does it exist8 ,what holds it in its vapory form8 ,how is it affected by cold substances8 ,describe the deposit of moisture on the outside of a pitcher in summer4 ,what other instances of the same action can be named8 ,it is well known that a cold pitcher in summer robs the vapor in the atmosphere of its heat1 and causes it to be deposited on its own surface4 ,it looks as though the pitcher were sweating1 but the water all comes from the atmosphere1 not1 of course1 through the sides of the pitcher4 ,if we breathe on a knife-blade1 it condenses in the same manner the moisture of the breath1 and becomes covered with a film of water4 ,stone houses are damp in summer1 because the inner surfaces of the walls1 being cooler than the atmosphere1 cause its moisture to be deposited in the manner described4 ,by leaving a space1 however1 between the walls and the plaster1 this moisture is prevented from being troublesome4 ,how does this principle affect the soil8 ,explain the experiment with the two boxes of soil4 ,nearly every night in the summer season1 the cold earth receives moisture from the atmosphere in the form of dew4 ,a cabbage1 which at night is very cold1 condenses water to the amount of a gill or more4 ,the same operation takes place in the soil4 ,when the air is allowed to circulate among its lower and cooler particles1 they receive moisture from the same process of condensation4 ,therefore1 when1 by the aid of under-drains1 the lower soil becomes sufficiently open to admit of a circulation of air1 the deposit of atmospheric moisture will keep the soil supplied with water at a point easily accessible to the roots of plants4 ,if we wish to satisfy ourselves that this is practically correct1 we have only to prepare two boxes of finely pulverized soil1 one1 five or six inches deep1 and the other fifteen or twenty inches deep1 and place them in the sun at mid-day in summer4 ,the thinner soil will be completely dried1 while the deeper one1 though it may have been perfectly dry at first1 will soon accumulate a large amount of water on those particles which1 being lower and more sheltered from the sun's heat than the particles of the thin soil1 are made cooler4 ,with an open condition of subsoil1 then1 such as may be secured by under-draining1 we entirely overcome drought4 ,how does under-draining supply to the soil an increased amount of atmospheric fertilizers8 ,how does it warm the lower parts of the soil8 #b4 ,under-draining furnishes an increased supply of atmospheric fertilizers1 because it secures a change of air in the soil4 ,this change is produced whenever the soil becomes filled with water1 and then dried2 when the air above the earth is in rapid motion1 and when the comparative temperature of the upper and lower soils changes4 ,it causes new quantities of the ammonia and carbonic acid which it contains to be presented to the absorbent parts of the soil4 #c4 ,under-draining warms the lower parts of the soil1 because the deposit of moisture 7#a7 is necessarily accompanied by an abstraction of heat from the atmospheric vapor1 and because heat is withdrawn from the whole amount of air circulating through the cooler soil4 ,when rain falls on the parched surface soil1 it robs it of a portion of its heat1 which is carried down to equalize the temperature for the whole depth4 ,the heat of the rain-water itself is given up to the soil1 leaving the water from one to ten degrees cooler1 when it passes out of the drains1 than when received by the earth4 ,there is always a current of air passing from the lower to the upper end of a well constructed drain2 and this air is always cooler in warm weather1 when it issues from1 than when it enters the drain4 ,its lost heat is imparted to the soil4 ,how does it hasten the decomposition of roots and other organic matter in the soil8 ,how does it accelerate the disintegration of its mineral parts8 ,why is this disintegration necessary to fertility8 ,this heating of the lower soil renders it more favorable to vegetation1 partially by expanding the spongioles at the end of the roots1 thus enabling them to absorb larger quantities of nutritious matters4 #d4 ,under-draining hastens the decomposition of roots and other organic matters in the soil1 by admitting increased quantities of air1 thus supplying oxygen1 which is as essential in decay as it is in combustion4 ,it also allows the resultant gases of decomposition to pass away1 leaving the air around the decaying substances in a condition to continue the process4 ,this organic decay1 besides its other benefits1 produces an amount of heat perfectly perceptible to the smaller roots of plants1 though not so to us4 #e4 ,draining accelerates the disintegration of the mineral matters in the soil1 by admitting water and oxygen to keep up the process4 ,this disintegration is necessary to fertility1 because the roots of plants can feed only on matters dissolved from surfaces2 and the more finely we pulverize the soil1 the more surface we expose4 ,for instance1 the interior of a stone can furnish no food for plants2 while1 if it were finely crushed1 it might make a fertile soil4 ,any thing1 tending to open the soil to exposure1 facilitates the disintegration of its particles1 and thereby increases its fertility4 ,how does under-draining equalize the distribution of the fertilizing parts of the soil8 ,why does this distribution lessen the impoverishment of the soil8 ,how does under-draining improve the mechanical texture of the soil8 ,how do drains affect the excrementitious matter of plants8 #f4 ,draining causes a more even distribution of nutritious matters among those parts of soil traversed by roots1 because it increases the ease with which water travels around1 descending by its own weight1 moving sideways by a desire to find its level1 or carried upward by attraction to supply the evaporation at the surface4 ,by this continued motion of the water1 soluble matter of one part of the soil may be carried to some other part2 and another constituent from this latter position may be carried back to the former4 ,thus the food of vegetables is continually circulating around among their roots1 ready for absorption at any point where it is needed1 while the more open character of the soil enables roots to occupy larger portions1 making a more even drain on the whole1 and preventing the undue impoverishment of any part4 #g4 ,under-drains improve the mechanical texture of the soil2 because1 by the decomposition of its parts1 as previously described 7#d and #e71 it is rendered of a character to be more easily worked2 while smooth round particles1 which have a tendency to pack1 are roughened by the oxidation of their surfaces1 and move less easily among each other4 #h4 ,drains cause the excrementitious matter of plants to be carried out of the reach of their roots4 ,nearly all plants return to the soil those parts of their food1 which are not adapted to their necessities1 and usually in a form that is poisonous to plants of the same kind4 ,in an open soil1 this matter may be carried by rains to a point where roots cannot reach it1 and where it may undergo such changes as will fit it to be again taken up4 ,why do they prevent grasses from running out8 #i4 ,by under-draining1 grasses are prevented from running out1 partly by preventing the accumulation of the poisonous excrementitious matter1 and partly because these grasses usually consist of tillering plants4 ,these plants continually reproduce themselves in sprouts from the upper parts of their roots4 ,these sprouts become independent plants1 and continue to tiller 7thus keeping the land supplied with a full growth71 until the roots of the stools 7or clumps of tillers71 come in contact with an uncongenial part of the soil1 when the tillering ceases2 the stools become extinct on the death of their plants1 and the grasses run out4 ,the open and healthy condition of soil produced by draining prevents the tillering from being stopped1 and thus keeps up a full growth of grass until the nutriment of the soil is exhausted4 #aj4 ,draining enables us to deepen the surface-soil1 because the admission of air and the decay of roots render the condition of the subsoil such that it may be brought up and mixed with the surface-soil1 without injuring its quality4 ,the second class of advantages of under-draining1 arising in the removal of the excess of water in the soil1 are quite as important as those just described4 ,how does the removal of water render soils earlier in spring8 ,why does it prevent the throwing out of grain in winter8 ,why does it enable us to work sooner after rains8 ,why does it keep off the effects of cold weather longer in the fall8 #aa4 ,soils are1 thereby1 rendered earlier in spring1 because the water1 which rendered them cold1 heavy1 and untillable1 is earlier removed1 leaving them earlier in a growing condition4 #ab4 ,the throwing out of grain in winter is prevented1 because the water falling on the earth is immediately removed instead of remaining to throw up the soil by freezing1 as it always does from the upright position taken by the particles of ice4 #ac4 ,we are enabled to work sooner after rains1 because the water descends1 and is immediately removed instead of lying to be taken off by the slow process of evaporation1 and sinking through a heavy soil4 #ad4 ,the effects of cold weather are kept off longer in the fall1 because the excess of water is removed1 which would produce an unfertile condition on the first appearance of cold weather4 ,the drains also1 from causes already named 7#c71 keep the soil warmer than before being drained1 thus actually lengthening the season1 by making the soil warm enough for vegetable growth earlier in spring1 and later in autumn4 ,how does it prevent lands from becoming sour8 ,why does it hasten the decay of roots1 and the comminution of mineral matters8 ,how does it prevent the abstraction of heat from the soil8 #ae4 ,lands are prevented from becoming sour by the formation of acetic acid1 etc41 because these acids are produced in the soil only when the decomposition of organic matter is arrested by the antiseptic 7preserving7 powers of water4 ,if the water is removed1 the decomposition of the organic matter assumes a healthy form1 while the acids already produced are neutralized by atmospheric influences1 and the soil is restored from sorrel to a condition in which it is fitted for the growth of more valuable plants4 #af4 ,the decay of roots1 etc41 is allowed to proceed1 because the preservative influence of too much water is removed4 ,wood1 leaves1 or other vegetable matter kept continually under water1 will last for ages2 while1 if exposed to the action of the weather1 as in under-drained soils1 they soon decay4 ,the presence of too much water1 by excluding the oxygen of the air1 prevents the comminution of matters necessary to fertility4 ,how much heat does water take up in becoming vapor8 ,why does water sprinkled on a floor render it cooler8 ,why is not a cubic inch of vapor warmer than a cubic inch of water8 ,why does a wet cloth on the head make it cooler when fanned8 ,how does this principle apply to the soil8 #ag4 ,the evaporation of water1 and the consequent abstraction of heat from the soil1 is in a great measure prevented by draining the water out at the bottom of the soil1 instead of leaving it to be dried off from the surface4 ,when water assumes the gaseous 7or vapory7 form1 it takes up #agbc times as much heat as it contained while a liquid4 ,a large part of this heat is derived from surrounding substances4 ,when water is sprinkled on the floor1 it cools the room2 because1 as it becomes a vapor1 it takes heat from the room4 ,the reason why vapor does not feel hotter than liquid water is1 that1 while it contains #agbc times as much heat1 it is #agbc as large4 ,hence1 a cubic inch of vapor1 into which we place the bulb of a thermometer1 contains no more heat than a cubic inch of water4 ,the principle is the same in some other cases4 ,a sponge containing a table-spoonful of water is just as wet as one twice as large and containing two spoonsful4 ,if a wet cloth be placed on the head1 and the evaporation of its water assisted by fanning1 the head becomes cooler--a portion of its heat being taken to sustain the vapory condition of the water4 ,the same principle holds true with the soil4 ,when the evaporation of water is rapidly going on1 by the assistance of the sun1 wind1 etc41 a large quantity of heat is abstracted1 and the soil becomes cold4 ,when there is no evaporation taking place1 except of water which has been deposited on the lower portions of soil1 and carried to the surface by capillary attraction 7as is nearly true on under-drained soils71 the loss of heat is compensated by that taken from the moisture in the atmosphere by the soil1 in the above-named manner4 ,this cooling of the soil by the evaporation of water1 is of very great injury to its powers of producing crops1 and the fact that under-drains avoid it1 is one of the best arguments in favor of their use4 ,some idea may1 perhaps1 be formed of the amount of heat taken from the soil in this way1 from the fact that1 in midsummer1 #be hogsheads of water may be evaporated from a single acre in twelve hours4 ,when rains are allowed to enter the soil1 how do they benefit it8 ,how do under-drains prevent the formation of a crust on the surface of a soil8 #ah4 ,when not saturated with water the soil admits the water of rains1 etc41 which bring with them fertilizing gases from the atmosphere1 to be deposited among the absorbent parts of soil1 and given up to the necessities of the plant4 ,when this rain falls on lands already saturated1 it cannot enter the soil1 but must run off from the surface1 or be removed by evaporation1 either of which is injurious4 ,the first1 because fertilizing matter is washed away4 ,the second1 because the soil is deprived of necessary heat4 #ai4 ,the formation of crust on the surface of the soil is due to the evaporation of water1 which is drawn up from below by capillary attraction4 ,it arises from the fact that the water in the soil is saturated with mineral substances1 which it leaves at its point of evaporation at the surface4 ,this soluble matter from below1 often forms a very hard crust1 which is a complete shield to prevent the admission of air with its ameliorating effects1 and should1 as far as possible1 be avoided4 ,under-draining is the best means of doing this1 as it is the best means of lessening the evaporation4 ,the foregoing are some of the more important reasons why under-draining is always beneficial4 ,thorough experiments have amply proved the truth of the theory4 ,what kinds of soil are benefited by under-draining8 ,the kinds of soil benefited by under-draining are nearly as unlimited as the kinds of soil in existence4 ,it is a common opinion1 among farmers1 that the only soils which require draining are those which are at times covered with water1 such as swamps and other low lands2 but the facts stated in the early part of this chapter1 show us that every kind of soil--wet1 dry1 compact1 or light--receives benefit from the treatment4 ,the fact that land is too dry1 is as much a reason why it should be drained1 as that it is too wet1 as it overcomes drought as effectually as it removes the injurious effects of too much water4 ,all soils in which the water of heavy rains does not immediately pass down to a depth of at least thirty inches1 should be under-drained1 and the operation1 if carried on with judgment1 would invariably result in profit4 ,what do ,english farmers name as the profits of under-draining8 ,what stand has been taken by the ,english government with regard to under-draining8 ,of the precise profits of under-draining this is not the place to speak3 many of the agricultural papers contain numerous accounts of its success4 ,it may be well to remark here1 that many ,english farmers give it1 as their experience1 that under-drains pay for themselves every three years1 or that they produce a perpetual profit of #cc-a_/c per cent41 or their original cost4 ,this is not the opinion of theorists and book farmers4 ,it is the conviction of practical men1 who know1 from experience1 that under-drains are beneficial4 ,the best evidence of the utility of under-draining is the position1 with regard to it1 which has been taken by the ,english national government1 which affords much protection to the agricultural interests of her people--a protection which in this country is unwisely and unjustly withheld4 ,in ,england a very large sum from the public treasury has been appropriated as a fund for loans1 on under-drains1 which is lent to farmers for the purpose of under-draining their estates1 the only security given being the increased value of the soil4 ,the time allowed for payments is twenty years1 and only five per cent4 interest is charged4 ,by the influence of this patronage1 the actual wealth of the kingdom is being rapidly increased1 while the farmers themselves1 can raise their farms to any desired state of fertility1 without immediate investment4 ,how does under-draining affect the healthfulness of marshy countries8 ,describe the sub-soil plow4 ,the best proof that the government has not acted injudiciously in this matter is1 that private capitalists are fast employing their money in the same manner1 and loans on under-drains are considered a very safe investment4 ,there is no doubt that we may soon have similar facilities for improving our farms1 and when we do1 we shall find that it is unnecessary to move ,west to find good soil4 ,the districts nearer market1 where the expense of transportation is much less1 may1 by the aid of under-drains1 and a judicious system of cultivation1 be made equally fertile4 ,one very important1 though not strictly agricultural1 effect of thorough drainage is its removal of certain local diseases1 peculiar to the vicinity of marshy or low moist soils4 ,the health-reports in several places in ,england1 show that where fever and ague was once common1 it has almost entirely disappeared since the general use of under-drains in those localities4 ,,chapter ,,iv4 ,,sub-,,soil ,,plowing4 ,describe the ,mapes plow4 ,why is the motion in the soil of one and a half inches sufficient8 ,how does the oxidation of the particles of the soil resemble the rusting of cannon balls in a pile8 ,the sub-soil plow is an implement differing in figure from the surface plow4 ,it does not turn a furrow1 but merely runs through the subsoil like a mole--loosening and making it finer by lifting1 but allowing it to fall back and occupy its former place4 ,it usually follows the surface plow1 entering the soil to the depth of from twelve to eighteen inches below the bottom of the surface furrow4 ,the best pattern now made 7the ,mapes plow7 is represented in the following figure4 ,illustration3 ,fig4 #h4 ,the ,mapes plow and its mode of action4 a--,shape of the foot of the plow1 b--,its effect on the soil4 ,the sub-soil plows first made raised the whole soil about eight inches1 and required very great power in their use often six1 eight1 or even ten oxen4 ,the ,mapes plow1 raising the soil but slightly1 may be worked with much less power1 and produces equally good results4 ,it may be run to its full depth in most soils by a single yoke of oxen4 ,of course a motion in the soil of but one and a half inches is very slight1 but it is sufficient to move each particle from the one next to it which1 in dry soils1 is all that is necessary4 ,whoever has examined a pile of cannon-balls must have observed that at the points where they touch each other1 there is a little rust4 ,in the soil1 the same is often the case4 ,where the particles touch each other1 there is such a chemical change produced as renders them fit for the use of plants4 ,while these particles remain in their first position1 the changed portions are out of the reach of roots2 but1 if1 by the aid of the sub-soil plow1 their position is altered1 these parts are exposed for the uses of plants4 ,if we hold in the hand a ball of dry clay1 and press it hard enough to produce the least motion among its particles1 the whole mass becomes pulverized4 ,on the same principle1 the sub-soil plow renders the compact lower soil sufficiently fine for the requirements of fertility4 ,why are the benefits of sub-soiling not permanent on wet lands8 ,does sub-soiling overcome drought8 ,how does it deepen the surface soil8 ,notwithstanding its great benefits on land1 which is sufficiently dry1 sub-soiling cannot be recommended for wet lands2 for1 in such case1 the rains of a single season would often be sufficient to entirely overcome its effects by packing the subsoil down to its former hardness4 ,on lands not overcharged with water1 it is productive of the best results1 it being often sufficient to turn the balance between a gaining and a losing business in farming4 ,it increases nearly every effect of under-draining2 especially does it overcome drought1 by loosening the soil1 and admitting air to circulate among the particles of the subsoil and deposit its moisture on the principle described in the chapter on under-draining4 ,it deepens the surface-soil1 because it admits roots into the subsoil where they decay and leave carbon1 while the circulation of air so affects the mineral parts1 that they become of a fertilizing character4 ,the deposit of carbon gives to the subsoil the power of absorbing1 and retaining the atmospheric fertilizers1 which are more freely presented1 owing to the fact that the air is allowed to circulate with greater freedom4 ,as a majority of roots decay in the surface-soil1 they there deposit much mineral matter obtained from the subsoil4 ,why is the retention of atmospheric manures ensured by sub-soiling8 ,why are organic manures plowed deeply under the soil1 less liable to evaporation than when deposited near the surface8 ,how does sub-soiling resemble under-draining in relation to the tillering of grasses8 ,when the subsoil consists of a thin layer of clay on a sandy bed1 what use may be made of the sub-soil plow8 ,the retention of atmospheric manures is more fully ensured by the better exposure of the clayey portions of the soil4 ,those manures which are artificially applied1 by being plowed under to greater depths1 are less liable to evaporation1 as1 from the greater amount of soil above them1 their escape will more probably be arrested2 and1 from the greater prevalence of roots1 they are more liable to be taken up by plants4 ,the subsoil often contains matters which are deficient in the surface-soil4 ,by the use of the sub-soil plow1 they are rendered available4 ,sub-soiling is similar to under-draining in continuing the tillering of grasses1 and in getting rid of the poisonous excrementitious matter of plants4 ,when the subsoil is a thin layer of clay on a sandy bed 7as in some plants of ,cumberland ,co4 ,maine71 the sub-soil plow1 by passing through it1 opens a passage for water1 and often affords a sufficient drainage4 ,to how great a depth will the roots of plants usually occupy the soil8 ,what is the object of loosening the soil8 ,how are these various effects better produced in deep than in shallow soils8 ,if plants will grow better on a soil six inches deep than on one of three inches1 there is no reason why they should not be benefited in proportion1 by disturbing the soil to the whole depth to which roots will travel--which is usually more than two feet4 ,the minute rootlets of corn and most other plants1 will1 if allowed by cultivation1 occupy the soil to the depth or thirty-four inches1 having a fibre in nearly every cubic inch of the soil for the whole distance4 ,there are very few cultivated plants whose roots would not travel to a depth of thirty inches or more4 ,even the onion sends its roots to the depth of eighteen inches when the soil is well cultivated4 ,the object of loosening the soil is to admit roots to a sufficient depth to hold the plant in its position--to obtain the nutriment necessary to its growth--to receive moisture from the lower portions of the soil--and1 if it be a bulb1 tuber1 or tap1 to assume the form requisite for its largest development4 ,it must be evident that roots1 penetrating the soil to a depth of two feet1 anchor the plant with greater stability than those which are spread more thinly near the surface4 ,the roots of plants traversing the soil to such great distances1 and being located in nearly every part1 absorb mineral and other food1 in solution in water1 only through the spongioles at their ends4 ,consequently1 by having these ends in every part of the soil1 it is all brought under contribution1 and the amount supplied is greater1 while the demand on any particular part may be less than when the whole requirements of plants have to be supplied from a depth of a few inches4 ,may garden soils be profitably imitated in field culture8 ,the ability of roots1 to assume a natural shape in the soil1 and grow to their largest sizes1 must depend on the condition of the soil4 ,if it is finely pulverized to the whole depth to which they ought to go1 they will be fully developed2 while1 if the soil be too hard for penetration1 they will be deformed or small4 ,thus a carrot may grow to the length of two and a half feet1 and be of perfect shape1 while1 if it meet in its course at a depth of eight or ten inches a cold1 hard subsoil1 its growth must be arrested1 or its form injured4 ,roots are turned aside by a hard sub-soil1 as they would be if received by the surface of a plate of glass4 ,add to this the fact that cold1 impenetrable subsoils are chemically uncongenial to vegetation1 and we have sufficient evidence of the importance1 and in many cases the absolute necessity of sub-soiling and under-draining4 ,it is unnecessary to urge the fact that a garden soil of two feet is more productive than a field soil of six inches2 and it is certain that proper attention to these two modes of cultivation will in a majority of cases make a garden of the field--more than doubling its value in ease of working1 increased produce1 certain security against drought1 and more even distribution of the demands on the soil--while the outlay will be immediately repaid by an increase of crops4 ,is the use of the sub-soil plow increasing8 ,will its use ever injure crops8 ,the subsoil will be much improved in its character the first year1 and a continual advancement renders it in time equal to the original surface-soil1 and extending to a depth of two feet or more4 ,the sub-soil plow is coming rapidly into use4 ,there are now in ,new ,jersey more foundries casting sub-soil plows than there were sub-soil plows in the ,state six years ago4 ,the implement has there1 as well as in many other places1 ceased to be a curiosity2 and the man who now objects to its use1 is classed with him who shells his corn on a shovel over a half-bushel1 instead of employing an improved machine1 which will enable him to do more in a day than he can do in the good old way in a week4 ,had we space1 we might give many instances of the success of sub-soiling1 but the agricultural papers of the present day 7at least one of which every farmer should take7 have so repeatedly published its advantages1 that we will not do so4 ,in no case will its use be found any thing but satisfactory1 except in occasional instances where there is some chemical difficulty in the subsoil1 which an analysis will tell us how to overcome4 ,as was before stated1 its use on wet lands is not advisable until they have been under-drained1 as excess of water prevents its effects from being permanent4 ,,chapter ,v4 ,,plowing ,,and ,,other ,,modes ,,of ,,pulverizing ,,the ,,soil4 ,may the satisfaction attending labor be increased by an understanding of the natural laws which regulate our operations8 ,on what depends the kind of plow to be used8 ,the advantages of pulverizing the soil1 and the reasons why it is necessary1 are now too well known to need remark4 ,few farmers1 when they plow1 dig1 or harrow1 are enabled to give substantial reasons for so doing4 ,if they will reflect on what has been said in the previous chapters1 concerning the supply of mineral food to the plant by the soil1 and the effect of air and moisture about roots1 they will find more satisfaction in their labor than it can afford when applied without thought4 ,,plowing4 ,what is a general rule with regard to this8 ,should deep plowing be immediately adopted8 ,why8 ,why is this course of treatment advisable for garden culture8 ,the kind of plow used in cultivating the surface-soil must be decided by the kind of soil4 ,this question the practical1 observing farmer will be able to solve4 ,as a general rule1 it may be stated that the plow which runs the deepest1 with the same amount of force1 is the best4 ,we might enter more fully into this matter but for want of space4 ,the advantages of deep plowing cannot be too strongly urged4 ,the statement that the deeper and the finer the soil is rendered1 the more productive it will become1 is in every respect true1 and which no single instance will contradict4 ,it must not be inferred from this1 that we would advise a farmer1 who has always plowed his soil to the depth of only six inches1 to double the depth at once4 ,such a practice in some soils would be highly injurious1 as it would completely bury the more fertile and better cultivated soil1 and bring to the top one which contains no organic matter1 and has never been subject to atmospheric influences4 ,this would1 perhaps1 be so little fitted for vegetation that it would scarcely sustain plants until their roots could reach the more fertile parts below4 ,such treatment of the soil 7turning it upside down7 is excellent in garden culture1 where the great amount of manures applied is sufficient to overcome the temporary barrenness of the soil1 but it is not to be recommended for all field cultivation1 where much less manure is employed4 ,how should field plowing be conducted8 ,how does such treatment affect soils previously limed8 ,how may it sometimes improve sandy or clay soils8 ,the course to be pursued in such cases is to plow one inch deeper each year4 ,by this means the soil maybe gradually deepened to any desired extent4 ,the amount of uncongenial soil which will thus be brought up1 is slight1 and will not interfere at all with the fertility of the soil1 while the elevated portion will become1 in one year1 so altered by exposure1 that it will equal the rest of the soil in fertility4 ,often where lime has been used in excess1 it has sunk to the subsoil1 where it remains inactive4 ,the slight deepening of the surface plowing would mix this lime with the surface-soil1 and render it again useful4 ,when the soil is light and sandy1 resting on a heavy clay subsoil1 or clay on sand1 the bringing up of the mass from below will improve the texture of the soil4 ,as an instance of the success of deep plowing1 we call to mind the case of a farmer in ,new ,jersey1 who had a field which had yielded about twenty-five bushels of corn per acre4 ,it had been cultivated at ordinary depths4 ,after laying it out in eight step lands 7#bd feet71 he plowed it at all depths from five to ten inches1 on the different lands1 and sowed oats evenly over the whole field4 ,the crop on the five inch soil was very poor1 on the six inch rather better1 on the seven inch better still1 and on the ten inch soil it was as fine as ever grew in ,new ,jersey2 it had stiff straw and broad leaves1 while the grain was also much better than on the remainder of the field4 ,what kind of soils are benefited by fall plowing8 ,there is an old anecdote of a man who died1 leaving his sons with the information that he had buried a pot of gold for them1 somewhere on the farm4 ,they commenced digging for the gold1 and dug over the whole farm to a great depth without finding the gold4 ,the digging1 however1 so enriched the soil that they were fully compensated for their disappointment1 and became wealthy from the increased produce of their farm4 ,farmers will find1 on experiment1 that they have gold buried in their soil1 if they will but dig deep enough to obtain it4 ,the law gives a man the ownership of the soil for an indefinite distance from the surface1 but few seem to realize that there is another farm below the one they are cultivating1 which is quite as valuable as the one on the surface1 if it were but properly worked4 ,fall plowing1 especially for heavy lands1 is a very good means of securing the action of the frosts of winter to pulverize the soil4 ,if it be a stiff clay1 it may be well to throw the soil up into ridges 7by ridging and back furrowing71 so as to expose the largest possible amount of surface to the freezing and thawing of winter4 ,sandy soils should not be plowed in the fall1 as it renders them too light4 ,,digging ,,machines4 ,what is the digging machine8 ,a recent invention has been made in ,england1 known as the digging machine or rotary spade1 which--although from having too much gearing between the power and the part performing the labor1 it is not adapted to general use--has given such promise of future success1 that ,mr4 ,mechi 7an agricultural writer of the highest standing7 has said that the plow is doomed4 ,this can hardly be true1 for the varied uses to which it may be applied1 will guarantee its continuance in the favor of the farmer4 ,already1 in this country1 ,messrs4 ,gibbs ,mapes1 have invented a digging machine of very simple construction1 which seems calculated to serve an excellent purpose1 even in the hands of the farmer of limited means4 ,its friends assert that1 with one pair of oxen1 it will dig perfectly three feet wide1 and for a depth of fifteen inches4 ,an experiment with an unperfected machine1 in the presence of the writer1 seemed to justify their hopes4 ,this machine thoroughly pulverizes the soil to a considerable depth1 and for smooth land must prove far superior to the plow4 ,,the ,,harrow ,,and ,,cultivator4 ,why is the harrow a defective implement8 ,why is the cultivator superior to the harrow8 ,the harrow1 an implement largely used in all parts of the world1 to pulverize the soil1 and break clods1 has become so firmly rooted in the affections of farmers1 that it must be a very long time before they can be convinced that it is not the best implement for the use to which it is devoted4 ,it is true that it pulverizes the soil for a depth of two or three inches1 and thus much improves its appearance1 benefiting it1 without doubt1 for the earliest stages of the growth of plants4 ,its action1 however1 is very defective1 because1 from the wedge shape of its teeth1 it continually acts to pack the soil2 thus--although favorable for the germination of the seed--it is not calculated to benefit the plant during the later stages of its growth1 when the roots require the soil to be pulverized to a considerable depth4 ,the cultivator may be considered an improved harrow4 ,the principal difference between them being1 that while the teeth of the harrow are pointed at the lower end1 those of the cultivator are shaped like a small double plow1 being large at the bottom and growing smaller towards the top4 ,they lift the earth up1 instead of pressing it downwards1 thus loosening instead of compacting the soil4 ,many styles of cultivators are now sold at agricultural warehouses4 ,a very good one1 for field use1 may be made by substituting the cultivator teeth for the spikes in an old harrow frame4 ,,chapter ,,vi4 ,,rolling1 ,,mulching1 ,,weeding1 ,,etc4 ,,rolling4 ,name some of the benefits of rolling8 ,rolling the soil with a large roller1 arranged to be drawn by a team1 is in many instances a good accessory to cultivation4 ,by its means1 the following results are obtained3-- #a4 ,the soil at the surface is pulverized without the compacting of the lower parts1 the area of contact being large4 #b4 ,the stones on the land are pressed down so as to be out of the way of the scythe in mowing4 #c4 ,the soil is compacted around seeds after sowing in such a manner as to exclude light and to touch them in every part1 both of which are essential to their germination and to the healthfulness of the plants4 ,under what circumstances should the roller be used8 #d4 ,the soil is so compacted at the surface1 that it is less frequented by grubs1 etc41 than when it is more loose4 #e4 ,when the soil is smoothed in this manner1 there is less surface exposed for the evaporation of water with its cooling effect4 #f4 ,light sandy lands1 by being rolled in the fall1 are rendered more compact1 and the loosening effects of frequent freezing and thawing are avoided4 ,although productive of these various effects1 rolling should be adopted only with much care1 and should never be applied to very heavy lands1 except in dry weather when lumpy after plowing1 as its tendency in such cases would be to render them still more difficult of cultivation4 ,soils in which air does not circulate freely1 are not improved by rolling1 as it presses the surface-particles still more closely together1 and prevents the free admission of the atmosphere4 ,if well under-drained1 a large majority of soils would doubtless be benefited by a judicious use of the roller4,,al ,,mulching4 ,what is mulching8 ,what are some of its benefits8 ,mulching 7called ,gurneyism in ,england7 consists in covering the soil with salt hay1 litter1 seaweed1 leaves1 spent tanbark1 chips1 or other refuse matter4 ,every farmer must have noticed that1 if a board or rail1 or an old brush-heap be removed in spring from soil where grass is growing1 the grass afterwards grows in those places much larger and better than in other parts of the field4 ,this improvement arises from various causes4 #a4 ,the evaporation of water from the soil is prevented during drought by the shade afforded by the mulch2 and it is therefore kept in better condition1 as to moisture and temperature1 than when evaporation goes on more freely4 ,this condition is well calculated to advance the chemical changes necessary to prepare the matters--both organic and mineral--in the soil for the use of plants4 #b4 ,by preventing evaporation1 we partially protect the soil from losing ammonia resultant from decaying organic matter4 #c4 ,a heavy mulch breaks the force of rains1 and prevents them from compacting the soil1 as would be the result1 were no such precaution taken4 #d4 ,mulching protects the surface-soil from freezing as readily as when exposed1 and thus keeps it longer open for the admission of air and moisture4 ,when unprotected1 the soil early becomes frozen2 and all water falling1 instead of entering as it should do1 passes off on the surface4 ,why does mulching take the place of artificial watering8 ,why is the late sowing of oats beneficial8 ,from what arises the chief benefit of top dressing the soil with manure in autumn8 #e4 ,the throwing out of winter grain is often prevented1 because this is due to the freezing of the surface-soil4 #f4 ,mulching prevents the growth of some weeds1 because it removes from them the fostering heat of the sun4 ,many of the best nursery-men keep the soil about the roots of young trees mulched continually4 ,one of the chief arguments for this treatment is1 that it prevents the removal of the moisture from the soil and the consequent loss of heat4 ,also that it keeps up a full supply of water for the uses of the roots1 because it keeps the soil cool1 and causes a deposit of dew4 #g4 ,it also prevents the baking of the soil1 or the formation of a crust4 ,it is to be recommended in nearly all cases to sow oats very thinly over land intended for winter fallow after the removal of crops1 as they will grow a little before being killed by the frost1 when they will fall down1 thus affording a very beneficial mulch to the soil4 ,when farmers spread manure on their fields in the fall to be plowed under in the spring1 they benefit the land by the mulching more than by the addition of fertilizing matter1 because they give it the protecting influence of the straw1 etc41 while they lose much of the ammonia of their manure by evaporation4 ,the same mulching might be more cheaply done with leaves1 or other refuse matter1 and the ammonia of the manure made available by composting with absorbents4 ,why is snow particularly beneficial8 ,it is an old and true saying that snow is the poor man's manure4 ,the reason why it is so beneficial is1 chiefly1 that it acts as a most excellent mulch4 ,it contains no more ammonia than rain-water does2 and1 were it not for the fact that it protects the soil against loss of heat1 and produces other benefits of mulching1 it would have no more advantageous effect4 ,the severity of winters at the ,north is partially compensated by the long duration of snow4 ,it is a well known fact that when there is but little snow in cold countries1 wheat is very liable to be winter killed4 ,the same protection is afforded by artificial mulching4 ,this treatment is peculiarly applicable to the cultivation of flowers1 both in pots and in beds out of doors4 ,it is almost indispensable to the profitable production of strawberries1 and many other garden crops1 such as asparagus1 rhubarb1 etc4 ,many say that the best treatment for trees is to put stones about their roots4 ,this is simply mulching them1 and might be done more cheaply by the use of leaves1 copying the action of nature in forests2,,am for1 unless these stones be removed in spring1 they will sink and compact the soil in part during open weather4 ,,weeding4 ,what are some of the uses of weeds8 ,their disadvantages8 ,if a farmer were asked--what is the use of weeds8 he might make out quite a list of their benefits1 among which might be some of the following3-- #a4 ,they shade tender plants1 and in a measure serve as a mulch to the ground4 #b4 ,some weeds1 by their offensive odor1 drive away many insects4 #c4 ,they may serve as a green crop to be plowed into the soil1 and increase its organic matter4 #d4 ,they make us stir the soil1 and thus increase its fertility4 ,still1 while thinking out these excuses for weeds1 he would see other and more urgent reasons why they should not be allowed to grow4 #a4 ,they occupy the soil to the disadvantage of crops4 #b4 ,they exclude light and heat from cultivated plants1 and thus interfere with their growth4 #c4 ,they take up mineral and other matters from the soil1 and hold them during the growing season1 thus depriving crops of their use4 ,it is not necessary to argue the injury done by weeds4 ,every farmer is well convinced that they should be destroyed1 and the best means of accomplishing this are of the greatest importance4 ,how may we protect ourselves against their increase8 ,why is it especially important for this purpose to maintain the balance of the soil8 ,in the first place1 we should protect ourselves against their increase4 ,this may be done3-- ,by decomposing all manures in compost1 whereby the seeds contained will be killed by the heat of fermentation2 or1 if one bushel of salt be mixed through each cord of compost 7as before recommended71 it will kill seeds as well as grubs1-- ,by hoeing1 or1 otherwise1 destroying growing weeds before they mature their seeds1 and ,by keeping the soil in the best chemical condition4 ,this last point is one of much importance4 ,it is well known that soils deficient in potash1 will naturally produce one kind of plants1 while soils deficient in phosphoric acid will produce plants of another species1 etc4 ,many soils produce certain weeds which would not grow on them if they were made chemically perfect1 as indicated by analysis4 ,it is also believed that those weeds1 which naturally grow on the most fertile soils1 are the ones most easily destroyed4 ,there are exceptions 7of which the ,thistle is one71 but this is given as a general rule4 ,how much salt may be used with advantage8 ,why is the scuffle-hoe superior to the common hoe8 ,by careful attention to the foregoing points1 weeds may be kept from increasing while those already in the soil may be eradicated in various ways1 chiefly by mechanical means1 such as hoeing1 plowing1 etc4,,an ,prof4 ,mapes says that six bushels of salt annually sown broadcast over each acre of land1 will destroy very many weeds as well as grubs and worms4 ,the common hoe is a very imperfect tool for the purpose of removing weeds1 as it prepares a better soil for1 and replants in a position to grow1 nearly as many weeds as it destroys4 ,the scuffle-hoe 7or push-hoe7 is much more effective1 as1 when worked by a man walking backwards1 and retiring as he works1 it leaves nearly all of the weeds on the surface of the soil to be killed by the sun4 ,when used in this way1 the earth is not trodden on after being hoed--as is the case when the common hoe is employed4 ,this treading1 besides compacting the soil1 covers the roots of many weeds1 and causes them to grow again4 ,how may much labor be saved in removing weeds8 ,what is the ,langdon horse-hoe8 ,describe the universal cultivator8 ,much of the labor of weeding usually performed by men1 might be more cheaply done by horses4 ,there are various implements for this purpose1 some of which are coming1 in many parts of the country1 into very general use4 ,one of the best of these is the ,langdon ,horse ,hoe1 which is a shovel-shaped plow1 to be run one or two inches deep4 ,it has a wing on each side to prevent the earth from falling on to the plants in the rows4 ,at the rear1 or upper edge1 is a kind of rake or comb1 which allows the earth to pass through1 while the weeds pass over the comb and fall on the surface of the soil1 to be killed by the heat of the sun4 ,it is a simple and cheap tool1 and will perform the work of twenty men with hoes4 ,the hand hoe will be necessary only in the rows4 ,,cultivator4 ,the cultivator1 which was described in the preceding chapter1 and of which there are various patterns in use1 is excellent for weeding1 and for loosening the soil between the rows of corn1 etc4 ,the one called the universal cultivator1 having its side bars made of iron1 curved so that at whatever distance it is placed the teeth will point straight forward1 is a much better tool than those of the older patterns1 which had the teeth so arranged that when set for wide rows1 they pointed towards the clevis4 ,it is difficult to keep such a cultivator in its place1 while the universal is as difficult to move out of a straight line4 ,,improved ,,horse-,,hoe4 ,what is the improved horse-hoe8 ,the improved horse-hoe is a combination of the ,langdon horse hoe and the cultivator1 and is the best implement1 for many purposes1 that has yet been made4,,ao ,illustration3 ,fig4 #i ,,harvesting ,,machines4 ,until within a comparatively short period1 but little attention has been paid to the production of machines for harvesting the various crops4 ,during the past few years1 however1 many valuable inventions have appeared4 ,among these we notice ,ketchum's mower1 ,hussey's mower and reaper1 and ,wagener's grain and grass seed harvester4 ,the latter machine gathers only the grain and seeds of the crop1 leaving the straw to be plowed under the soil1 thus maintaining its supply of soluble silicates1 and increasing its amount of organic matter4 ,after taking the seed heads from the standing straw and grasses1 it thrashes them1 blows out the chaff1 separates the different kinds of seeds1 and discharges them into bags ready for market4 ,it consists of a car containing the machinery2 to this may be attached any required number of horses4 ,the inventor affirms that it has harvested the grain of two acres in one hour1 performing the work with accuracy4,,ap 99 99 99 99 99 ,there is much truth in the following proverbs3 ,a garden that is well kept1 is kept easily4 ,you must conquer weeds1 or weeds will conquer you4 ,what are the two great rules in mechanical cultivation8 ,it is almost impossible to give a recapitulation of the matters treated in this section1 as it is1 itself1 but an outline of subjects which might occupy our whole book4 ,the scholar and the farmer should understand every principle which it contains1 as well as they understand the multiplication table2 and their application will be found1 in every instance1 to produce the best results4 ,the two great rules of mechanical cultivation are-- ,,thorough ,,under-,,draining4 ,,deep ,,and ,,frequent ,,disturbance ,,of ,,the ,,soil4 ,,footnotes3 ,,al ,field rollers should be made in sections1 for ease of turning4 ,,am ,the beneficial effects of mulching is so great as to lead us to the conclusion that it has other means of action than those mentioned in this book4 ,future experiments may lead to more knowledge on this subject4 ,,an ,it is possible that the excrementitious matter thrown out by some plants may be sufficiently destructive to other kinds to exterminate them from the soil--thus1 farmers in ,maine say that a single crop of turnips will entirely rid the soil of witch grass4 ,this is1 undoubtedly1 the effect of the excrementitious matter of the turnips4 ,this subject is one of practical importance1 and demands close investigation by farmers1 which may lead to its being reduced to a system4 ,,ao ,the improved horse-hoe is made and sold by ,ruggles1 ,nourse ,mason1 of ,worcester1 ,mass41 and ,quincy ,hall1 ,boston4 ,,ap ,this machine is more fully noticed in the advertising pages4 ,,section ,,fifth4 ,,analysis4 ,,chapter ,i4 ,why does true practical economy require that the soil should be analyzed8 ,at the present time1 when such marked improvements have been1 and are still being made1 in the practice of agriculture1 the farmer cannot be too strongly advised to procure an analysis of his soil1 and for obvious reasons4 ,it has been sufficiently proved that the plant draws from the soil certain kinds of mineral matter1 in certain proportions2 also1 that if the soil do not contain the constituents required1 the plants cannot obtain them1 and consequently cannot grow4 ,furthermore1 in proportion to the ability of the soil to supply these materials1 in exactly the same proportion will it1 when under good treatment1 produce good and abundant crops4 ,can each farmer make his own analyses8 ,why will not travelling chemists answer the purpose8 ,how must an analysis be used8 ,all admit the value and the necessity of manures2 they are required to make up deficiencies in the soil1 and consequently1 they must supply to it the matters which are wanting4 ,in order to know what is wanting1 we must know the composition of the soil4 ,this can be learned only by accurate chemical analysis4 ,such an analysis every farmer must possess before he can conduct his operations with true practical economy4 ,an important question now arises as to whether each farmer can make his own analyses4 ,he cannot do so without long study and practice4 ,the late ,prof4 ,norton said that1 at least two years' time would be necessary to enable a man to become competent to make a reliable analysis4 ,when we reflect that a farmer may never need more than five or six analyses1 we shall see that the time necessary to learn the art would be much more valuable than the cost of the analyses 7at #e or #aj each71 setting aside the cost of apparatus1 and the fact that while practising in the laboratory1 he must not use his hands for any labor that would unfit them for the most delicate manipulations4 ,neither will travelling chemists be able to make analyses as accurately and as cheaply as those who work in their own laboratories1 where their apparatus is not liable to the many injuries consequent on frequent removal4 ,the cost of sending one hundred samples of soil to a distant chemist1 would be much less than the expense of having his apparatus brought to the town where his services are required4 ,how may a farmer obtain the requisite knowledge8 ,when are the services of a consulting agriculturist required8 ,the way in which an analysis should be used is a matter of much importance4 ,to a man who knows nothing of chemistry 7be he ever so successful a farmer71 an analysis1 as received from a chemist1 would be as useless and unintelligible as though it were written in ,chinese2 while1 if a chemist who knew nothing of farming1 were to give him advice concerning the application of manures1 he would be led equally astray1 and his course would be any thing but practical4 ,it is necessary that chemical and practical knowledge should be combined1 and then the value of analysis will be fully demonstrated4 ,the amount of knowledge required is not great1 but it must be thorough4 ,the information contained in this little book is sufficient1 but it would be folly for a man to attempt to use an analysis from reading it once hurriedly over4 ,it must be studied and thought on with great care1 before it can be of material assistance4 ,the evenings of one winter1 devoted to this subject1 will enable a farmer to understand the application of analysis to practical farming1 especially if other and more compendious works are also read4 ,a less time could hardly be recommended4 ,is there any doubt as to the practical value of analysis8 ,how should samples of soil for analysis be selected8 ,where this attention cannot be given to the subject1 the services of a ,consulting ,agriculturist should be employed to advise the treatment necessary to render fertile the soil analyzed4 ,every farmer1 however1 should learn enough of the principles of agriculture to be able to use an analysis1 when procured1 without such assistance4,,aq ,nearly all scientific men 7all of the highest merit7 are unanimous in their conviction of the practical value of an analysis of soils2 and a volume of instances of their success1 with hardly a single failure1 might be published4 ,prof4 ,mapes says1 in the ,working ,farmer1 that he has given advice on hundreds of different soils1 and not a single instance can be found where he has failed to produce a profit greater than the cost of analysis and advice4 ,dr4 ,t4 ,c4 ,jackson1 of ,boston1 the late ,prof4 ,norton1 of ,yale ,college1 and others1 have had universal success in this matter4 ,analysis must be considered the only sure road to economical farming4 ,to select samples of soil for analysis1 take a spadeful from various parts of the field--going to exactly the depth to which it has been plowed--until1 say a wheel-barrow full1 has been obtained4 ,mix this well together1 and send about a quart or a pint of it 7free from stones7 to the chemist4 ,this will represent all of that part of the farm which has been subject to the same cultivation1 and is of the same mechanical character4 ,if there are marked differences in the kinds of soil1 separate analyses will be necessary4 ,give an instance of the success of treatment according to analysis8 ,when an analysis is obtained1 a regular debtor and creditor account may be kept with the soil2 and the farmer may know by the composition of the ashes of his crops1 and the manures supplied1 whether he is maintaining the fertility of his soil4 ,prof4 ,mapes once purchased some land which could not produce corn at all1 and by applying only such manures as analysis indicated to be necessary1 at a cost of less than #b per acre1 he obtained the first year over fifty bushels of shelled corn per acre4 ,the land has since continued to improve1 and is as fertile as any in the ,state4 ,it has produced in one season a sufficient crop of cabbages to pay the expense of cultivation1 and over #bej per acre besides1 though it was apparently worthless when he purchased it4 ,these are strong facts1 and should arouse the farmers of the whole country to their true interests4 ,let them not call the teachings of science book-farming1 but prove all things--hold fast that which is good4 ,,footnotes3 ,,aq ,see ,author's card in the front of the book4 ,,chapter ,,ii4 ,,tables ,,of

,who is the practical farmer8 ,let us look at two pictures and decide4 ,here is a farm of #ajj acres in ordinary condition4 ,it is owned and tilled by a hard-working man1 who1 in the busy season1 employs one or two assistants4 ,the farm is free from debt1 but it does not produce an abundant income2 therefore1 its owner cannot afford to purchase the best implements1 or make other needed improvements2 besides1 he don't believe in such things4 ,his father was a good solid farmer2 so was his grandfather2 and so is he1 or thinks he is4 ,he is satisfied that 'the good old way' is best1 and he sticks to it4 ,he works from morning till night2 from spring till fall4 ,in the winter1 he rests1 as much as his lessened duties will allow4 ,during this time1 he reads little1 or nothing4 ,least of all does he read about farming4 ,he don't want to learn how to dig potatoes out of a book4 ,book farming is nonsense4 ,many other similar ideas keep him from agricultural reading4 ,his house is comfortable1 and his barns are quite as good as his neighbors'1 while his farm gives him a living4 ,it is true that his soil does not produce as much as it did ten years ago2 but prices are better1 and he is satisfied4 ,let us look at his premises1 and see how his affairs are managed4 ,first1 examine the land4 ,well1 it is good fair land4 ,some of it is a little springy1 but is not to be called wet4 ,it will produce a ton and a half of hay to the acre--it used to produce two tons4 ,there are some stones on the land1 but not enough in his estimation to do harm4 ,the plowed fields are pretty good2 they will produce #ce bushels of corn1 #ac bushels of wheat1 or #cj bushels of oats per acre1 when the season is not dry4 ,his father used to get more2 but1 somehow1 the weather is not so favorable as it was in old times4 ,he has thought of raising root crops1 but they take more labor than he can afford to hire4 ,over1 in the back part of the land there is a muck-hole1 which is the only piece of worthless land on the whole farm4 ,now1 let us look at the barns and barn-yards4 ,the stables are pretty good4 ,there are some wide cracks in the siding1 but they help to ventilate1 and make it healthier for the cattle4 ,the manure is thrown out of the back windows1 and is left in piles under the eaves on the sunny side of the barn4 ,the rain and sun make it nicer to handle4 ,the cattle have to go some distance for water2 and this gives them exercise4 ,all of the cattle are not kept in the stable2 the fattening stock are kept in the various fields1 where hay is fed out to them from the stack4 ,the barn-yard is often occupied by cattle1 and is covered with their manure1 which lies there until it is carted on to the land4 ,in the shed are the tools of the farm1 consisting of carts1 plows--not deep plows1 this farmer thinks it best to have roots near the surface of the soil where they can have the benefit of the sun's heat1--a harrow1 hoes1 rakes1 etc4 ,these tools are all in good order2 and1 unlike those of his less prudent neighbor1 they are protected from the weather4 ,the crops are cultivated with the plow1 and hoe1 as they have been since the land was cleared1 and as they always will be until this man dies4 ,here is the 'practical farmer' of the present day4 ,hard working1 out of debt1 and economical--of dollars and cents1 if not of soil and manures4 ,he is a better farmer than two thirds of the three millions of farmers in the country4 ,he is one of the best farmers in his town--there are but few better in the county1 not many in the ,state4 ,he represents the better class of his profession4 ,with all this1 he is1 in matters relating to his business1 an unreading1 unthinking man4 ,he knows nothing of the first principles of farming1 and is successful by the indulgence of nature1 not because he understands her1 and is able to make the most of her assistance4 ,this is an unpleasant fact1 but it is one which cannot be denied4 ,we do not say this to disparage the farmer1 but to arouse him to a realization of his position and of his power to improve it4 ,but let us see where he is wrong4 ,he is wrong in thinking that his land does not need draining4 ,he is wrong in being satisfied with one and a half tons of hay to the acre when he might easily get two and a half4 ,he is wrong in not removing as far as possible every stone that can interfere with the deep and thorough cultivation of his soil4 ,he is wrong in reaping less than his father did1 when he should get more4 ,he is wrong in ascribing to the weather1 and similar causes1 what is due to the actual impoverishment of his soil4 ,he is wrong in not raising turnips1 carrots1 and other roots1 which his winter stock so much need1 when they might be raised at a cost of less than one third of their value as food4 ,he is wrong in considering worthless a deposit of muck1 which is a mine of wealth if properly employed4 ,he is wrong in ventilating his stables at the cost of heat4 ,he is wrong in his treatment of his manures1 for he loses more than one half of their value from evaporation1 fermentation1 and leaching4 ,he is wrong in not having water at hand for his cattle--their exercise detracts from their accumulation of fat and their production of heat1 and it exposes them to cold4 ,he is wrong in not protecting his fattening stock from the cold of winter2 for1 under exposure to cold1 the food1 which would otherwise be used in the formation of fat1 goes to the production of the animal heat necessary to counteract the chilling influence of the weather1 p4 #ej4 ,he is wrong in allowing his manure to lie unprotected in the barn-yard4 ,he is wrong in not adding to his tools the deep surface plow1 the subsoil plow1 the cultivator1 and many others of improved construction4 ,he is wrong in cultivating with the plow and hoe1 those crops which could be better or more cheaply managed with the cultivator or horse-hoe4 ,he is wrong in many things more1 as we shall see if we examine all of his yearly routine of work4 ,he is right in a few things2 and but a few1 as he himself would admit1 had he that knowledge of his business which he could obtain in the leisure hours of a single winter4 ,still1 he thinks himself a practical farmer4 ,in twenty years1 we shall have fewer such1 for our young men have the mental capacity and mental energy necessary to raise them to the highest point of practical education1 and to that point they are gradually but surely rising4 ,let us now place this same farm in the hands of an educated and understanding cultivator2 and1 at the end of five years1 look at it again4 ,he has sold one half of it1 and cultivates but fifty acres4 ,the money for which the other fifty were sold has been used in the improvement of the farm4 ,the land has all been under-drained1 and shows the many improvements consequent on such treatment4 ,the stones and small rocks have been removed1 leaving the surface of the soil smooth1 and allowing the use of the sub-soil plow1 which with the under-drains have more than doubled the productive power of the farm4 ,sufficient labor is employed to cultivate with improved tools1 extensive root crops1 and they invariably give a large yield4 ,the grass land produces a yearly average of #b tons of hay per acre4 ,from #hj to #ajj bushels of corn1 #cj bushels of wheat1 and #de bushels of oats are the average of the crops reaped4 ,the soil has been analyzed1 and put in the best possible condition1 while it is yearly supplied with manures containing every thing taken away in the abundant crops4 ,the analysis is never lost sight of in the regulation of crops and the application of manures4 ,the worthless muck bed was retained1 and is made worth one dollar a load to the compost heap1 especially as the land requires an increase of organic matter4 ,a new barn has been built large enough to store all of the hay produced on the farm4 ,it has stables1 which are tight and warm1 and are well ventilated above the cattle4 ,the stock being thus protected from the loss of their heat1 give more milk1 and make more fat on a less amount of food than they did under the old system4 ,water is near at hand1 and the animals are not obliged to over exercise4 ,the manure is carefully composted1 either under a shed constructed for the purpose with a tank and pump1 or is thrown into the cellar below1 where the hogs mix it with a large amount of muck1 which has been carted in after being thoroughly decomposed by the lime and salt mixture4 ,they are thus protected against all loss1 and are prepared for the immediate use of crops4 ,no manures are allowed to lie in the barn-yard1 but they are all early removed to the compost heap1 where they are preserved by being mixed with carbonaceous matter4 ,in the tool shed1 we find deep surface-plows1 sub-soil plows1 cultivators1 horse-hoes1 seed-drills1 and many other valuable improvements4 ,this farmer takes one or more agricultural papers1 from which he learns many new methods of cultivation1 while his knowledge of the reasons of various agricultural effects enables him to discard the injudicious suggestions of mere book farmers and uneducated dreamers4 ,here are two specimens of farmers4 ,neither description is over-drawn4 ,the first is much more careful in his operations than the majority of our rural population4 ,the second is no better than many who may be found in ,america4 ,we appeal to the common sense of the reader of this work to know which of the two is the practical farmer--let him imitate

,geology1 a ,catechism of ,agricultural ,chemistry and ,geology1 c4 ,,advertisement4 ,the common life of man is full of wonders1 ,chemical and ,physiological4 ,most of us pass through this life without seeing or being sensible of them1 though every day our existence and our comforts ought to recall them to our minds4 ,one main cause of this is1 that our schools tell us nothing about them--do not teach those parts of modern learning which would fit us for seeing them4 ,what most concerns the things that daily occupy our attention and cares1 are in early life almost sedulously kept from our knowledge4 ,those who would learn any thing regarding them1 must subsequently teach themselves through the help of the press3 hence the necessity for a ,popular ,chemical ,literature4 ,it is with a view to meet this want of the ,public1 and at the same time to supply a ,manual for the ,schools1 that the present work has been projected4 ,it treats1 in what appears to be their natural order1 of ,,the ,,air ,,we ,,breathe and ,,the ,,water ,,we ,,drink1 in their relations to human life and health--,,the ,,soil ,,we ,,cultivate ,,and ,,the ,,plant ,,we ,,rear1 as the sources from which the chief sustenance of all life is obtained--,,the ,,bread ,,we ,,eat ,,and ,,the ,,beef ,,we ,,cook1 as the representatives of the two grand divisions of human food--,,the ,,beverages ,,we ,,infuse1 from which so much of the comfort of modern life1 both savage and civilized1 is derived--,,the ,,sweets ,,we ,,extract1 the history of which presents so striking an illustration of the economical value of chemical science--,,the ,,liquors ,,we ,,ferment1 so different from the sweets in their action on the system1 and yet so closely connected with them in chemical history--,,the ,,narcotics ,,we ,,indulge ,,in1 as presenting us with an aspect of the human constitution which1 both chemically and physiologically1 is more mysterious and wonderful than any other we are acquainted with--,,the ,,odours ,,we ,,enjoy ,,and ,,the ,,smells ,,we ,,dislike2 the former because of the beautiful illustration it presents of the recent progress of organic chemistry in its relations to comforts of common life1 and the latter because of its intimate connection with our most important sanitary arrangements--,,what ,,we ,,breathe ,,for and ,,why ,,we ,,digest1 as functions of the body at once the most important to life1 and the most purely chemical in their nature--,,the ,,body ,,we ,,cherish1 as presenting many striking phenomena1 and performing many interesting chemical functions not touched upon in the discussion of the preceding topics--and lastly1 ,,the ,,circulation ,,of ,,matter1 as exhibiting in one view the end1 purpose1 and method of all the changes in the natural body1 in organic nature1 and in the mineral kingdom1 which are connected with and determine the existence of life4 ,it has been the object of the ,author in this ,work to exhibit the present condition of chemical knowledge and of matured scientific opinion upon the subjects to which it is devoted4 ,the reader will not be surprised1 therefore1 should he find in it some things which differ from what is to be
