,,uncle ,,robert',s ,,visit ,,by ,,francis ,w4 ,,parker ,,and ,,nellie ,,lathrop ,,helm ,,preface ,,by ,,the ,,editor ,,of ,,the ,,home-,,reading ,,books4 ,the publishers take pleasure in offering to the public1 in their ,home-,reading ,series1 some books relating to the farm and other aspects of country life as the center of interest1 written by ,colonel ,francis ,w4 ,parker1 the ,president of the famous ,cook ,county ,normal ,school1 in ,chicago4 ,for many years the teachers of the common schools of the country have been benefited by the inventions of ,colonel ,parker in the way of methods of teaching in the schoolroom4 ,his enthusiasm has led him to consider the best means of arousing the interest of the child and of promoting his self-activity for reasonable purposes4 ,the ,pestalozzian movement in the history of education is justly famed for its effort to connect in a proper manner the daily experience of the child with the school course of study4 ,the branches of learning taught to the child by the schoolmaster are necessarily dry and juiceless if they are not thus brought into relation with the child's world of experience4 ,almost all of the school reforms that have been proposed in the past one hundred years have moved in this line4 ,the effort to seize upon the child's interest and make it the agency for progress has formed the essential feature in each4 ,in this reform movement ,colonel ,parker has made himself one of the chief influences4 ,the rural school has held a low rank among educational institutions on account of the inferior methods of instruction which have prevailed by reason of the fact that the children were too few and their qualifications too various to permit the forming of classes4 ,children in various degrees of advancement from ,,abc's to higher arithmetic1 and yet numbering only ten1 twenty1 or thirty in all1 are enrolled under one teacher4 ,most branches of study could muster only one or two pupils in each class3 ,five to ten minutes a day is all that can be allowed in such cases for a recitation4 ,no thoroughness of instruction on the part of the teacher is possible1 nor is there much improvement to be expected in the method of instruction where classes can not be formed4 ,the benefactor of the country school therefore looks to other devices than class instruction1 and the author of this book has shown in what ways the teacher of one of these small schools may extend his influence into the families of his district1 encourage home study initiate practical experiments4 ,it is expected that the teacher1 besides his daily register in which he records the names and attendance of his own pupils1 will keep a list of the youth of the district who have been in attendance on the school but have left to take up the work of the farm1 and that he will endeavor by proper means to persuade them to enter upon well-planned courses of reading4 ,occasional meetings in the evening at central places1 or on some afternoons of the week at the schoolhouse itself1 will furnish occasions for the discussion of the contents of the books that have been read1 and experiments will be suggested in the way of verifying the theories advanced in them4 ,not only can the mind of the country youth be broadened and enlarged in the direction of literature and art1 and of science and history1 but it can be made more practical by focusing it upon the problems connected with the agriculture and manufactures of the district4 ,this indicates a career of usefulness for the ambitious teacher of a rural school4 ,there is a large field for the discipline of the directive power open even for the humblest of teachers in the land4 ,these books of ,colonel ,parker1 if read by the school children1 and especially by the elder youth who have left school1 will suggest a great variety of ways in which real mental growth and increase of practical power may be obtained4 ,the ideal of education in the ,united ,states is that the child in school shall be furnished with a knowledge of the printed page and rendered able to get out of books the experience of his fellow-men1 and at the same time be taught how to verify and extend his book knowledge by investigations on his environment4 ,this having been achieved by the school1 nothing except his indolence1 or1 to give it a better name1 want of enterprise1 prevents the individual citizen from growing intellectually and practically throughout his whole life4 ,w4 ,t4 ,,harris4 ,,washington1 ,d4,c41 ,august #ab1 #ahig4 ,,author',s ,,preface ,fortunate are the children whose early years are spent in the country in close contact with the boundless riches which ,nature bestows4 ,amid these environments instinct and spontaneity do a marvelous work in the growing minds of children1 arousing and sustaining varied and various interests1 enhancing mental activities1 and furnishing an educative outlet for lively energies4 ,most fortunate are they to whom1 at the moment when the unconscious teachings of ,nature need to be supplemented by thoughtful suggestion1 wise leadings1 and judicious instruction1 there comes one with a deep and loving sympathy with child life1 an active interest in all that interests them1 and a profound respect for all that children do well and for all that they know4 ,such an one is ,uncle ,robert4 ,he comes to the children at just the right moment4 ,he directs the sweet strong streams of their lives onward into a channel of earnest inquiry and exalted labor1 which is ever broadening and deepening4 ,uncle ,robert's aim in education is to fill each day with acts which make home better1 the community better1 mankind better2 to take from ,god's bounteous and boundless store of truth and convert it into human life by using it4 ,his method is simple and direct1 founded upon the firm rock1 ,common ,sense4 ,it may be briefly stated as follows3 #a4 ,a strong belief in the sacredness of work--that work which inspires thought1 strengthens the body as well as the mind1 and develops the feeling of usefulness4 #b4 ,the images the children have acquired and the inferences they have made are used as stepping stones to higher and broader views4 #c4 ,so far as it is possible1 each child is to discover facts for himself and make original inferences4 #d4 ,he understands the limits of children's power to observe and the demand on their part for glimpses into1 to them1 the great unknown4 ,so he tells them stories of those things which lie beyond their horizon1 in order to excite their wonder1 intensify their love for the objects that surround them1 and make them more careful observers4 ,in this way a hunger and thirst for books is created4 #e4 ,he watches carefully the interests of each child1 adapting his teachings to the differences in age and personality4 #f4 ,some questions are left unanswered in order to stimulate that healthy curiosity which can be satisfied only by persistent study--the study that begets courage and confidence4 #g4 ,he makes farm work and farm life full of intensely interesting problems1 ever keeping in mind that the things of which the common environments of common lives are made up are as well worthy of study as are those which lie beyond4 ,uncle ,robert's enthusiasm has for its prime impulse a boundless faith in human progress1 brought about by a knowledge of childhood and its possibilities4 ,he believes that every normal child1 under wise and loving guidance1 may become useful to his fellows1 moral in character1 strong in intellect1 with a body which is an efficient instrument of the soul2 in other words1 truly educated4 ,those who read ,uncle ,robert's ,visit should read through the eyes of ,susie1 ,donald1 and ,frank4 ,the reading1 so far as possible1 should be accompanied by personal observation1 investigation1 and experiment4 ,,francis ,w4 ,,parker4 ,,chicago ,,normal ,,school1 ,august #ca1 #ahig4 ,,contents4 ,i4 ,,uncle ,,robert',s

plant1 animal1 and human life4 ,popular opinion has given the name of geography to these correlated subjects4 ,,chapter ,i4--,,uncle ,,robert',s ,,coming4 ,the value of the children's knowledge of the farm is warmly recognized by ,uncle ,robert4 ,the children feel his sympathy for their work1 and through it are led to closer study and investigation4 ,the feeling that everything they may see and do is of importance1 exalts their daily life4 ,encourage children to describe the farms on which they live4 ,in such descriptions should come plant and animal life1 and the means and processes of farm work4 ,extend these descriptions to other farms and to any landscapes which the children have observed4 ,,chapter ,,ii4--,,frank ,,draws ,a ,,map ,,of ,,the ,,farm4 ,all children love to draw1 and they will draw with great confidence and boldness unless their critical faculty outruns their skill4 ,modeling and painting may be very profitably introduced at an early age4 ,frank's efforts in drawing strengthened his images of the landscape4 ,arithmetic has a very important place in farm life4 ,it may be used in many ways in forming habits of accuracy and exactness4 ,,chapter ,,iii4--,,the ,,new ,,thermometer4 ,the children have their first lesson on the agent of all physical movement and change in organic and inorganic matter4 ,the simple experiments suggested should be continued and enlarged1 thus beginning a life study of a subject which is practically unlimited in its importance to man4 ,,chapter ,,iv4--,,with ,,the ,,animals4 ,children look upon animals as their particular friends and acquaintances4 ,they talk to them and believe that the animals understand them4 ,a desire to know the habits and habitats of animals is among their strongest interests4 ,by a little wise direction1 this interest may be so enhanced as to form a substantial beginning of the study of zoology4 ,,chapter ,v4--,,in ,,the ,,flower ,,garden4 ,children worship flowers4 ,probably there are no objects on earth so universally loved by little folks as buds and flowers4 ,children seek eagerly for flowers by the roadside1 in the pastures1 fields1 and woods4 ,this love1 like all instincts1 should be carefully cultivated4 ,children may easily be led to study the forms1 colors1 and habits of plants4 ,they will always take the keenest interest in the mystery of seeds and shoots1 of roots and growing leaves1 if there is a teacher to direct them4 ,,chapter ,,vi4--,,sunlight ,,and ,,shadow4 ,we have heat again1 and now as an elementary lesson in the distribution of sunshine4 ,children love to observe continual changes4 ,the shadow is an object of interest4 ,it has an element of mystery about it which borders upon the supernatural4 ,children observe spontaneously the long shadows of morning and the lengthening shadows of the descending sun4 ,most farm boys can tell the moment of noon by their shadows4 ,these are all steps in the more difficult problems of lengthening and shortening shadows that mark the changing seasons1 and that lead to the theories of the earth's rotation and revolution4 ,day by day children should note the changes of slant upon the shadow stick which they can easily make for themselves4 ,,chapter ,,vii4--,,the ,,barometer4 ,our little friends have their first lesson concerning one of the three great envelopes of the earth-the atmosphere4 ,the knowledge that air has weight does not often come by unaided intuition4 ,the initial experiments may be made very interesting and profitable4 ,the ,united ,states ,weather ,reports are an excellent means for the home study of geography4 ,,chapter ,,viii4--,a ,,walk ,,in ,,the ,,woods4 ,there is pleasure in the pathless woods and ,the groves were ,god's first temples are lines which appeal strongly to those who have spent hours in the shadows and flickering sunlight of the forest4 ,trees well arranged make many farmhouses beautiful4 ,trees by the roadside add much beauty to the landscape and afford places of rest to the traveler4 ,forests mean moisture to the soil4 ,their leaves and roots make the best reservoirs for water1 to be given out when needed by the growing crops4 ,the forests are full of lessons for the children and the experienced scientist4 ,,chapter ,,ix4--,,the ,,birds ,,and ,,the ,,flowers4 ,the knowledge of a farm child is quite extensive1 and generally neither the child nor the parent has any suspicion that such knowledge is of any appreciable value in education4 ,it is clearly within the bounds of possibility for every farm boy and girl to know every bird that lives on the farm in summer or winter1 and those who rest there in their migrating flight2 to know also the names1 the plumage1 the habits of all the birds2 and to know the nests and nesting places of those who make the farm their summer home4 ,all this study cultivates the child's sense of the beautiful4 ,there is no better color study in the world than that which springs from discriminating love of flowers and of the plumage of birds4 ,such study creates a kindly feeling toward both animals and plants on the part of the child4 ,it exercises a strong moral power over him4 ,,chapter ,x4--,,the ,,thundershower4 ,a thundershower is always a phenomenon of interest and often of fear on the part of children4 ,the clouds of the cumulus form1 the rolling of thunder1 the lightning flashes1 the rushing wind1 and the pouring rain are full of important lessons4 ,fear vanishes as knowledge comes4 ,in the thundershower is the question of the distribution of moisture over the earth's surface1 the question of the nature and use of clouds1 the movement of the air and wind1 the condensation of vapor1 and the marvelous powers of electricity4 ,,chapter ,,xi4--,,the ,,village4 ,geography should ever be in the closest touch with the human side4 ,nature does a marvelous work1 but ,nature without society is like a vast storehouse of treasure without a demand for its use4 ,the one weak point in farm life is the lack of opportunity for contact with society4 ,,chapter ,,xii4--,a ,,day ,,on ,,the ,,river4 ,a river1 creek1 lake--in fact1 any body of water--is a source of perpetual delight to children4 ,frank1 ,donald1 and ,susie have had the river and creek before them all their lives4 ,now1 under ,uncle ,robert's teaching1 the river will mean very much more to them4 ,they take their first lessons in the work of streams in carving and shaping the earth's surface4 ,the pebbles on the beach and the large1 rounded stones will soon have stories of the distant past to tell them4 ,the ,big ,book is opened to them1 and they read the stories directly from its pages4 ,,chapter ,,xiii4--,a ,,rainy ,,day4 ,the children get closer to the question of moisture1 its use1 and distribution4 ,the rain gauge helps them to measure the rainfall4 ,then comes the problem of where the water goes after it reaches the ground4 ,how far down does some of it go8 ,when and where does it come out of the ground8 ,arithmetic is brought in in measuring the rainfall and its distribution4 ,,chapter ,,xiv4--,,the ,,walk ,,after ,,the ,,rain4 ,the problems in ,chapter ,,xiii move toward their solution1 and new questions are opened4 ,the gully tells of the wearing of the water1 and foretells a river valley4 ,the spring helps in the question of underground water4 ,the flowing river quickens the imagination in the direction of the great ocean4 ,,chapter ,,xv4--,,the ,,big ,,book4 ,this chapter should be read by parents to the children1 as many sentences need expansion and explanation4 ,hints are given of great things which lie beyond the child's horizon4 ,discoveries that have changed mankind are referred to4 ,children's permanent interests are the keynotes of instruction and the infallible guides of the teacher4 ,to continue and sustain their spontaneous observation and desire for investigation leads directly to the study of the best books1 and lays the basis for a thorough and profound study of ,god's universe4 ,,chapter ,i4 ,,uncle ,,robert',s ,,coming4 ,uncle ,robert was coming4 ,his letter1 telling when they should expect him1 had been received a week before4 ,every day since had been full of talks and plans for his visit1 and now the day was come4 ,everything was ready4 ,frank and ,donald had harnessed ,nell1 the old white horse1 to the little spring wagon1 and had driven to the village to meet the train which was to bring ,uncle ,robert from ,new ,york4 ,susie1 in her prettiest white apron1 ran out of the house every few minutes1 to be the first to see them when they should come along the road4 ,mrs4 ,leonard was putting finishing touches here and there4 ,she went into the kitchen to give ,jane a last direction about the supper4 ,then she went to the east room upstairs1 ,uncle ,robert's room1 to be sure that everything was just as she knew he would like it4 ,susie followed her mother1 to see if the violets in the glass on his table were still bright and fresh4 ,she had gathered them herself in the woods that morning4 ,there they come6 she cried4 ,i hear the wagon crossing the bridge at the creek6 ,she ran quickly downstairs and out upon the piazza4 ,a moment more1 and the wagon turned in at the gate4 ,mother1 mother1 called ,susie1 they're here6 ,but ,mrs4 ,leonard was already beside her4 ,her pleasant face glowed with a happy smile as ,frank drew rein before the door4 ,then such a time6 ,uncle ,robert sprang from the seat beside ,frank1 hugged ,mrs4 ,leonard1 then ,susie1 then both together4 ,donald1 who was seated in the back of the wagon on ,uncle ,robert's trunk1 turned a handspring1 landed on his feet somehow or other1 and stood grinning at ,susie4 ,mr4 ,leonard had also heard the sound of the wheels4 ,he hurried from the barn1 calling ,peter to come and help him carry ,uncle ,robert's trunk upstairs4 ,jane came to the door of the dining-room1 eager to see the ,uncle ,robert of whom she had heard so much4 ,then1 with a nod of her head1 she ran back1 slipped the pan of biscuits into the oven1 and put the kettle on to boil4 ,uncle ,robert had come6 ,everybody was happy4 ,no one more so than ,uncle ,robert himself4 ,now1 this is good1 he said1 when at length they were seated around the supper table4 ,i feel at home already4 ,susie1 did those violets on my table grow in your garden8 ,illustration3 ,violets4 ,oh1 no1 replied ,susie4 ,i found them in the woods by the creek4 ,and the buttercups1 didn't you see them in the glass1 too8 ,buttercups so early 8 asked ,uncle ,robert4 ,oh1 yes1 the low ones do come early4 ,you must take me down where they grow some day4 ,we'll go to-morrow1 said ,susie4 ,uncle ,robert smiled at the eager little face1 and1 turning to ,mr4 ,leonard1 said3 ,frank tells me the farm is looking well this spring4 ,yes1 it looks fairly well1 replied ,mr4 ,leonard4 ,the seed is all in but the corn4 ,that is a little late4 ,the water on the bottom land stayed longer than usual this year4 ,peter thinks we can start the planting to-morrow1 said ,frank4 ,yes1 replied his father1 ,i think so1 too4 ,when supper was over they all went out on the side porch4 ,the sun was setting4 ,the air was soft and spring-like4 ,the lilacs along the fence filled the air with fragrance4 ,don't you want to see ,susie's garden1 ,robert8 asked ,mrs4 ,leonard1 ,yes1 indeed1 said ,uncle ,robert4 ,susie wrote me some nice little letters about that garden4 ,as they walked along the narrow paths ,susie showed him where the seeds were already planted1 and told him what she thought she would have in the other beds4 ,this is phlox1 said ,susie1 leading ,uncle ,robert by the hand2 and marigolds are here1 and sweet peas over there by the fence4 ,that place between mother's garden and mine is filled with rosebushes1 syringas1 and hollyhocks4 ,i still call the vegetable garden mine1 but the boys do most of the work1 said ,mrs4 ,leonard4 ,that big bush at the end of the row is an elder4 ,this is to be my pansy bed1 said ,susie4 ,the pansies are not set out yet4 ,they are growing in a box in the kitchen window4 ,i love them best of all4 ,don't they look like funny little faces in bonnets8 ,illustration3 ,pansies4 ,that is what the ,germans think1 ,susie1 said ,uncle ,robert1 laughing4 ,they call them 'little stepmothers4' ,i think it will be safe to put them out soon1 ,susie1 said ,mrs4 ,leonard4 ,mother1 called ,donald from the vegetable garden1 the lettuce and radishes are growing finely1 and here's a bean4 ,oh1 there are lots of them just putting their heads through6 ,they all went over to look at the beans1 and then walked down to the end of the garden where the currant and gooseberry bushes grew4 ,oh1 uncle1 exclaimed ,susie1 ,i wish you had come in time to see the trees in blossom6 ,they were all pink and white4 ,it was just lovely6 only the flowers stayed such a little while4 ,i think ,susie lived in the orchard those days1 said ,mrs4 ,leonard1 smiling4 ,if ,i wanted her ,i was very sure to find her there4 ,i don't blame ,susie1 said ,uncle ,robert4 ,i would have stayed1 too4 ,there is nothing sweeter than apple blossoms4 ,but you have other fruits besides apples1 haven't you8 ,illustration3 ,apple ,blossoms4 ,oh1 yes1 said ,frank1 who had just come from the barn1 where he had gone after supper with his father4 ,there are pears and cherries and a few peach trees4 ,but peaches don't do well here4 ,the blossoms are lovely1 said ,susie4 ,i believe ,susie cares more for the flowers than she does for the fruit1 said ,donald4 ,i don't4 ,i like the fruit1 and plenty of it4 ,how many kinds of apples have you8 asked ,uncle ,robert4 ,about ten1 replied ,frank4 ,but father budded quite a number last year4 ,the twigs came from ,kansas4 ,they have fine apples in ,kansas some years1 said ,uncle ,robert4 ,i wonder if the budding is done as it was when ,i was a boy on the farm in ,new ,england4 ,this is the way father did it1 said ,frank4 ,first he cut a little piece of the bark off the twig with the bud on it4 ,he had to do it very carefully with a sharp knife4 ,then he cut the bark on the branch of the tree like the letter ,t4 ,he laid it back1 and slipped the piece of bark with the bud on under it4 ,then he bound it all up with soft cotton1 and left it to take care of itself4 ,did it8 asked ,uncle ,robert4 ,yes1 answered ,donald4 ,in a few weeks we took the binding off1 and the bark had all grown together around the little bud4 ,illustration3 ,budding ,there were ever so many of them1 said ,susie1 and they were all alike4 ,i wish they would hurry up and have some apples on them1 said ,donald4 ,if they're better than some we had last year1 they'll be pretty good4 ,come1 children1 said ,mrs4 ,leonard4 ,it is getting damp4 ,i think we'd better go in now4 ,,chapter ,,ii4 ,,frank ,,draws ,a ,,map ,,of ,,the ,,farm4 ,after the lamps were lighted and they were all gathered in the sitting-room ,uncle ,robert began asking the children about the farm4 ,what do you raise besides corn8 he asked4 ,wheat1 oats1 rye1 and potatoes1 said ,frank4 ,then we have the hay fields and the pasture4 ,the woods we drove through coming from town belong to us too4 ,the house faces east1 doesn't it8 said ,uncle ,robert4 ,that would make the woods north4 ,where are all these other fields8 ,back of the barn and the other side of the orchard1 said ,donald4 ,can't some one show me on paper how it is8 asked ,uncle ,robert4 ,i don't mean make a picture1 but just a plan of it4 ,well1 ,i can try1 said ,frank4 ,i know just how it is really1 but ,i don't know that ,i can get it right4 ,frank found paper and pencil and set to work1 while the rest gathered eagerly around and looked on4 ,this is the river1 he said4 ,there's a big curve in it along our farm4 ,the road runs along the top of the slope1 and this is where the house is4 ,what lies between the house and the river8 asked ,uncle ,robert4 ,the big cornfield1 said ,frank4 ,that's where we are going to plant to-morrow if it is a pleasant day4 ,and right here1 in the corner by the woods1 is the spring4 ,the water comes right out of the ground1 said ,susie2 and it is as cold as ice4 ,here1 said ,frank1 is the wood4 ,you know we drove through it this afternoon4 ,the woods are on both sides of the creek4 ,see the crooked line he makes for the creek1 said ,donald4 ,that is where the violets and buttercups grow1 uncle1 said ,susie1 pointing to the map4 ,where does the creek come from8 asked ,uncle ,robert4 ,there's a pond away back in the woods1 said ,donald4 ,it comes from that2 but it is a swamp part of the year4 ,the cat-tails grow there1 said ,susie4 ,well1 said ,uncle ,robert1 the house1 the cornfield1 and the woods--is that all of the farm8 ,oh1 no6 said ,frank4 ,it is low along the river1 but back of the cornfield it gets higher1 and that's where the grapes are4 ,on this side of the road is the orchard2 and here1 between the orchard and the woods1 come in the yard and garden4 ,don't leave out the barnyard1 said ,donald4 ,what's back of the barn8 asked ,uncle ,robert4 ,the field of timothy2 and next to it is the clover field4 ,that is as far as the farm goes that way4 ,illustration3 ,,clover ,,timothy ,,wheat ,,oats ,,rye ,the wheat field is on the other side of the timothy1 ,frank1 said ,donald1 and the oats between that and the road1 beside the orchard4 ,put in the potatoes along the road1 said ,susie4 ,now all we have left is the rye field over in the corner1 said ,donald4 ,that is the way it is this year1 said ,mr4 ,leonard1 who sat with his paper in his hand4 ,but the paper was unread4 ,he found the group around the table much more interesting4 ,now it is all done1 said ,susie1 hopping about on one foot4 ,isn't it fun8 ,let's draw the garden4 ,i can do it4 ,all right1 said ,uncle ,robert1 you shall2 but ,i think we'd better finish the farm first4 ,who can tell how many acres there are in each of these lots8 ,i know there are twenty in the timothy meadow1 said ,donald1 because father always calls it the twenty-acre lot4 ,write it down on the map1 ,frank1 said ,uncle ,robert4 ,how much in the clover field8 ,it seems about half as large as the timothy meadow1 said ,frank4 ,that's right1 said ,mr4 ,leonard2 it is4 ,there are twenty acres in the wood lot1 aren't there1 father8 asked ,frank4 ,it isn't quite so wide1 but it is longer than the timothy meadow4 ,yes1 said ,mr4 ,leonard1 there are twenty acres there2 and it is as fine woodland as any ,i know4 ,there are ten acres in the orchard1 said ,frank2 and the cornfield is the largest of all4 ,that must be thirty acres1 said ,donald4 ,i remember when father made the pasture smaller1 so that we could have more corn4 ,yes1 said ,frank2 and that left ten in the pasture4 ,i remember4 ,and there are fifteen acres each in oats1 wheat1 and rye2 but ,i don't know how large the potato field is4 ,it is smaller than the others1 though--it must be about ten4 ,right again1 said ,mr4 ,leonard4 ,illustration3 7figures1 addition1 subtraction7 ,now we have it all but the yard and garden1 said ,uncle ,robert4 ,does any one know how much land they cover8 ,the father and mother looked on smiling1 but said nothing4 ,it's all the rest of the farm1 anyhow1 said ,susie4 ,oh1 ,i know how to find out1 said ,frank4 ,we know the whole farm is one hundred and sixty acres4 ,we can add all these figures1 and the difference between that and one hundred and sixty will be what's in the yard and garden4 ,so he added all the numbers together and found them to be one hundred and fifty-five4 ,yes1 exclaimed ,donald2 and five more would make it one hundred and sixty4 ,then there must be five acres in the yard and garden4 said ,susie1 ,write it down4 ,frank4 ,there1 said ,frank1 looking at his work with some pride4 ,it's all in4 ,now shall ,i draw it again and make the lines straighter8 ,illustration3 ,map of the farm4 ,oh1 no2 this tells the story very well1 said ,uncle ,robert4 ,the next time we will measure it off1 and make it more carefully4 ,not so bad1 said ,mr4 ,leonard1 as ,frank showed him the drawing4 ,i think it is very good for a first time1 said ,mrs4 ,leonard1 with an encouraging smile4 ,with a little practice1 my boy1 ,i believe you would draw well4 ,mother always believes we can do things1 said ,frank1 laughing4 ,tell me more about the river1 said ,uncle ,robert4 ,our side is bottom land1 said ,frank2 but across the river the bank is high and steep4 ,farther down it is just the other way4 ,the steep bank is on this side1 and the low land is opposite4 ,the river bends the other way down there1 said ,donald4 ,i see1 said ,uncle ,robert4 ,how high is the bank8 ,i don't know1 answered ,frank4 ,how high is it1 father8 ,about twenty feet1 said ,mr4 ,leonard4 ,do you go on the river much8 asked ,uncle ,robert4 ,oh1 yes1 said ,donald4 ,we have an old boat1 and we have been miles on it4 ,that is1 downstream1 said ,frank4 ,we have never taken the boat up the river beyond the village1 on account of the milldam4 ,there's an island in the river1 said ,susie1 between here and the village4 ,we have been there4 ,how large an island is it8 asked ,uncle ,robert--large enough to have a picnic there while ,i am here8 ,oh1 yes1 said ,susie4 ,it's just the loveliest place for a picnic6 ,there are trees all over it1 and all kinds of wild flowers4 ,can't you extend your map1 ,frank1 so as to put in the river to the village1 showing the milldam and the island8 suggested ,uncle ,robert4 ,you might draw it this way1 too1 said ,donald1 and show how the river bends the other way down here4 ,now ,i want to draw my garden1 said ,susie1 when ,frank had finished4 ,just then the clock on the kitchen shelf struck loudly4 ,it's bedtime now1 dear1 said ,mrs4 ,leonard4 ,can't you draw your garden to-morrow8 ,we'll plant those pansies to-morrow1 said ,uncle ,robert1 and see what can be put in all the other beds4 ,then we'll draw it1 and tell just where everything is4 ,so ,susie went to bed happy1 and ,frank and ,donald soon followed4 ,and all were glad that ,uncle ,robert was really come4 ,,chapter ,,iii4 ,,the ,,new ,,thermometer4 ,the next morning as they left the breakfast table ,donald said3 ,it's going to be warmer to-day4 ,i think not1 said ,frank4 ,when ,i went to the barn it seemed quite cool4 ,what do you think1 ,susie8 asked ,uncle ,robert4 ,it was cool under the trees when ,i went to the spring for a pitcher of water1 said ,susie1 but it seemed rather warm in the sun4 ,i think it is a lovely morning4 ,what makes it warm8 asked ,uncle ,robert4 ,why1 the sun1 replied ,donald1 looking rather surprised at such a question4 ,but does the sun make it warm in the winter8 asked ,uncle ,robert4 ,the sun is nearer the earth in spring and summer1 said ,frank confidently4 ,you are mistaken1 said ,uncle ,robert4 ,the sun is farther from us in summer than it is in winter4 ,but it's almost over our heads in summer1 said ,frank4 ,how can it be farther away8 ,the story of the warmth that the sun gives us is not told by distance1 said ,uncle ,robert1 but by the length of the shadows at noon4 ,how is that8 asked ,donald4 ,when is your shadow the longest8 asked ,uncle ,robert4 ,in the evening1 said ,donald4 ,in the morning1 said ,susie4 ,when is your shadow the shortest8 ,at noon6 they all shouted4 ,when is it coolest8 ,morning1 they replied together4 ,when is it warmest8 ,noon1 said ,susie quickly4 ,now you are wrong1 said ,frank4 ,it is often warmer at one or two o'clock4 ,frank is right1 said ,uncle ,robert4 ,how can we tell just how warm it is at any time8 ,if we had a thermometer1 said ,donald1 that would tell1 but we haven't4 ,there's one at the post office1 said ,frank1 but ,i never saw any one look at it unless it was very cold or very hot4 ,perhaps we can find one nearer than the post office1 said ,uncle ,robert4 ,susie1 would you know one if you saw it8 ,susie shook her head4 ,i would1 said ,donald4 ,well1 said ,uncle ,robert1 please go to my room1 and if you find a thermometer bring it to me4 ,donald soon returned1 and when ,susie saw what he had in his hand she exclaimed3 ,is that a thermometer8 ,i never saw anything like that at the post office4 ,well1 ,i should think not1 said ,donald4 ,this isn't much like the old thing they have up there4 ,what does it say8 asked ,uncle ,robert4 ,sixty-eight degrees above zero1 said ,frank1 taking the thermometer in his hand4 ,illustration3 ,thermometer4 ,that isn't cold1 is it1 uncle8 asked ,donald4 ,that's just right for the house1 said ,uncle ,robert4 ,how is it out of doors8 ,let's take it out and see1 said ,frank4 ,out on the porch they went and eagerly watched the thermometer4 ,it's moving--it's going down6 cried ,donald4 ,i'll hang it on this nail1 said ,frank4 ,when they looked again ,donald said3 ,it's fifty-six now4 ,how much colder is it than it was in the house8 asked ,uncle ,robert4 ,twelve degrees1 said ,frank1 counting up the column4 ,oh1 let's take it in by the stove1 said ,susie1 and see how far it will go up4 ,what makes you think it will go up by the stove8 asked ,uncle ,robert4 ,well1 answered ,susie1 if it goes down when it is cold ,i should think it would go up when it is warm4 ,susie took the little instrument1 and1 going into the kitchen1 held it close to the stove4 ,come1 she called1 it is going up already4 ,see6 ,how fast it moves6 said ,donald4 ,hold it close to the stove1 ,susie4 ,maybe it will go to the very top4 ,let us put it in cold water1 said ,frank4 ,it won't hurt the thermometer1 will it8 ,not at all1 was the reply4 ,try it4 ,so they held it in the bucket of cold spring water4 ,how fast it goes down now6 said ,susie4 ,i wonder if it will go lower than it did out on the porch4 ,it's down to forty-eight4 ,why does ,jane set the kettle of cold water on the stove8 asked ,uncle ,robert1 pointing to it4 ,to boil the water1 answered ,susie4 ,what makes the water boil8 ,why1 the fire1 of course4 ,how long will the stove stay hot8 ,as long as there is fire in it4 ,longer than that1 said ,donald4 ,it doesn't grow cold the minute the fire is out4 ,what becomes of all the heat8 asked ,uncle ,robert4 ,oh1 it goes all round the room4 ,let's put the thermometer in the hot water1 said ,susie4 ,oh1 see it go up6 said ,donald4 ,it is one hundred and fifteen already4 ,what is the difference in degrees between the cold and the hot water8 asked ,uncle ,robert4 ,sixty-seven degrees1 said ,frank4 ,what makes the difference in degrees8 ,the difference in the heat1 said ,frank4 ,if the water was boiling and the thermometer large enough1 said ,uncle ,robert1 it would go to two hundred and twelve4 ,that would be ninety-seven degrees higher1 said ,frank4 ,wouldn't that be a big thermometer6 exclaimed ,susie4 ,now put the thermometer on the floor1 said ,uncle ,robert4 ,it's seventy-two degrees now1 said ,donald in a few minutes4 ,let's put it on the broom1 said ,susie1 and hold it up to the ceiling4 ,it's warmer up there1 said ,frank1 looking at the little gray cylinder when they brought it down4 ,it is six degrees higher than it was on the floor4 ,why8 asked ,uncle ,robert4 ,the heat must go up there1 said ,donald4 ,it goes into the next room when the door is open1 said ,frank4 ,does it go outdoors8 asked ,uncle ,robert4 ,let's open the window and see1 said ,susie4 ,frank opened the window1 but1 instead of feeling the warm air going out1 he felt the cool air coming in4 ,uncle1 asked ,donald1 isn't the room full of air already8 ,yes1 answered ,uncle ,robert4 ,then ,i don't see how any more can come in at the window4 ,are you sure none goes out8 ,i could feel it coming in1 said ,frank4 ,jane1 asked ,uncle ,robert1 have you a candle8 ,here is one1 sir1 said ,jane1 taking a candlestick from beside the clock on the shelf4 ,uncle ,robert lighted it and held it near the window1 just below the sill4 ,the flame flickered as the air from the window struck it1 and then turned straight into the room4 ,he raised it just above the opening4 ,instantly the flame pointed toward the window1 but it did not flicker as it had when held below the sill4 ,the air must be going out up there1 said ,frank1 but it doesn't blow so strongly as the air coming in4 ,the air that comes in is cooler than the air that goes out1 said ,donald4 ,what makes the water boil8 asked ,uncle ,robert1 turning to the kettle on the stove1 which had now begun to sing4 ,why1 the heat1 of course1 said ,donald4 ,what raises the lid8 asked ,uncle ,robert4 ,the kettle is too full1 said ,frank4 ,it is going to boil over4 ,why didn't the water run over when it was cold8 asked ,uncle ,robert4 ,the kettle didn't seem full then4 ,somehow it seems to get more than full when it boils1 said ,donald4 ,see1 it is boiling over4 ,just then ,jane took a pan of apples out of the oven4 ,each one looked like a small volcano4 ,what happens to the apples when they bake8 asked ,uncle ,robert4 ,they just swell up so big their jackets won't hold them1 said ,donald1 laughing4 ,it is heat that makes the bread rise1 isn't it8 asked ,frank4 ,of course1 said ,susie4 ,don't you know sometimes if the bread doesn't rise1 mother says it is because it is too cold8 ,there is something besides heat that makes the bread rise1 said ,uncle ,robert4 ,yes1 replied ,susie1 the yeast2 but it must be warm--,i know it must4 ,it seems as though everything is bigger when it is hot than when it is cold1 said ,frank4 ,and now ,i believe ,i understand something that happened not long ago4 ,what was it8 asked ,uncle ,robert4 ,peter and ,i were driving to town1 began ,frank1 and the tire of one of the wagon wheels slipped right off4 ,we managed to get to the blacksmith's shop1 and he put the tire in the fire until it was hot4 ,then he put it on the wheel1 but it was still loose4 ,we couldn't have gone a step without its coming off again4 ,he brought cold water and poured over it1 and soon it was as tight as could be4 ,i thought the water made the wood of the wheel swell up--you know water does that to the pails and tubs when they leak2 but now ,i believe the fire made the tire larger1 and then the cold water made it small again4 ,that is just what happened4 ,illustration3 ,the blacksmith shop4 ,but air can't grow bigger1 can it8 asked ,donald4 ,if you can find an empty bottle1 ,donald1 said ,uncle ,robert1 perhaps we can soon find out about it4 ,uncle ,robert took a piece of thin rubber out of his pocket and tied it tightly over the mouth of the bottle4 ,by the way1 he said1 is there anything in this bottle8 ,no1 said ,susie1 looking through the glass4 ,oh1 yes1 said ,donald1 there is air in it4 ,well1 replied ,uncle ,robert1 please get a pan of hot water1 ,frank4 ,frank brought the water1 and as ,uncle ,robert began to put the bottle into it they all exclaimed3 ,be careful2 you'll break the bottle6 ,what will make it break8 asked ,uncle ,robert1 pausing4 ,why1 the hot water1 said ,susie4 ,it always breaks glass if you put it in too quickly1 said ,donald4 ,illustration ,well1 we'll warm it a little first1 holding the bottle close to the water4 ,i think ,i can try it now4 ,as he spoke he lowered the bottle into the water1 and the rubber tied over the neck began to bulge out4 ,see6 cried ,susie4 ,what makes it do that8 ,try the cold now1 said ,uncle ,robert4 ,here1 ,donald1 hold the bottle in this pail of cold water4 ,the rubber is going down1 said ,donald in a moment4 ,it is going right into the bottle4 ,does the air in the bottle pull the rubber in with it8 asked ,susie4 ,but1 ,uncle ,robert1 said ,donald1 what if wagon tires1 apples1 and air do swell up when they are hot8 ,i don't see what all that has to do with the thermometer4 ,i think ,i see1 said ,frank4 ,why wouldn't this gray stuff in the thermometer get bigger when it's hot1 if everything else does8 ,what is it that moves up and down in the thermometer8 asked ,susie4 ,it is mercury1 answered ,uncle ,robert1 which is sometimes called quicksilver4 ,it looks like silver1 said ,susie1 examining it closely4 ,perhaps you can see this better1 said ,uncle ,robert1 taking a small bottle of mercury from his pocket and pouring a little into ,donald's hand4 ,how heavy it is6 exclaimed he1 letting it roll about4 ,it feels just like lead4 ,it is almost twice as heavy as lead1 replied ,uncle ,robert4 ,put it in my hand1 ,donald1 said ,susie4 ,there1 you've spilled it on the floor6 ,just see it run around6 ,is it always soft like this8 asked ,frank4 ,no1 it becomes hard when it is very1 very cold4 ,how cold1 uncle8 asked ,donald1 looking at the thermometer4 ,thirty-nine or forty degrees below zero1 was the reply4 ,in the coldest of countries alcohol thermometers are used4 ,it must be much colder than that to freeze alcohol4 ,why is mercury used1 uncle8 asked ,frank4 ,because it takes a very great heat to make it boil4 said ,uncle ,robert4 ,then you have seen how quickly it shows a change of temperature4 ,when it is warm we call it a high temperature1 and when it is cold it is called a low temperature4 ,that is because the mercury goes up when it is hot1 and down when it is cold1 isn't it8 said ,donald4 ,i wonder how it would feel if it was forty degrees below zero4 ,see1 it is away down to there6 ,do you remember that day last winter when ,peter froze his ears driving to town8 asked ,frank4 ,well1 it was twenty below that day at the post office4 ,i saw it4 ,but father is calling me2 ,i must go4 ,,chapter ,,iv4 ,,with ,,the ,,animals4 ,don't forget to set that hen1 ,donald1 called ,mr4 ,leonard1 as he and ,frank went away together4 ,i think there are enough of those ,plymouth ,rock eggs for one more setting4 ,you ought to see our little chickens1 ,uncle ,robert1 said ,susie4 ,they are just too cunning for anything4 ,when you go to set the hen1 ,donald1 said ,uncle ,robert1 ,i will go with you4 ,then you can show me everything about the barn4 ,donald went to the storeroom and soon came back with the eggs4 ,there are thirteen1 he said1 as he joined ,uncle ,robert in the porch1 but ,i think she can take care of them4 ,she's one of the largest hens we have4 ,then together they went to the henhouse1 which stood next to the barn4 ,the chickens1 seeing the basket in ,donald's hand1 ran toward him4 ,you needn't think ,i am going to feed you again so soon1 he said4 ,you have had one breakfast this morning4 ,donald always talked to all the animals as though they could understand him4 ,illustration3 ,the poultry yard4 ,the mother hens paid no attention4 ,with quiet dignity they walked about1 their broods of fluffy little chicks looking like balls of gold in the sunshine4 ,with a ,cluck6 cluck6 each anxious mother called her children to her as her sharp eyes discovered some new dainty4 ,then the greedy little yellow things ran as fast as their short legs could carry them to be the first to take the good things from the self-sacrificing mother4 ,how many little chickens are there8 asked ,uncle ,robert as they stopped to watch them4 ,there are forty-six hatched1 said ,donald4 ,three hens are setting1 and this one will make four4 ,i see you have some fine turkeys1 too1 said ,uncle ,robert4 ,the big turkey cock spread his tail and strutted about before them as if he understood how much he was admired4 ,mother thinks a great deal of her turkeys1 said ,donald4 ,they are much harder to raise than the chickens4 ,but mother knows just how to do it4 ,we don't lose many4 ,have you ducks and geese1 too8 asked ,uncle ,robert4 ,yes1 said ,donald1 but ,i don't see any of them about4 ,they must have gone to the creek4 ,there they are1 and ,donald pointed toward the pasture where a line of white could be seen moving slowly along under the trees4 ,they march pretty well1 don't they8 said ,uncle ,robert4 ,do they always go that way8 ,not always1 said ,donald1 but very often4 ,when that old drake wants to take a swim1 he starts and the rest follow4 ,you'd never catch him walking behind4 ,as the head of the family ,i suppose he thinks it is his place to lead1 said ,uncle ,robert1 smiling4 ,donald laughed4 ,wouldn't it he funny1 he said1 if father made us follow him that way8 ,they found the hen to whom they were carrying the eggs on an empty nest4 ,donald drove her off that he might put in the eggs1 but she was very cross with him for disturbing her4 ,she walked about with her feathers ruffled up1 clucking angrily1 but eagerly went back to her nest as soon as they were gone4 ,she moved the eggs about with her feet1 placed them to suit herself1 and contentedly settled down4 ,donald then led ,uncle ,robert into the barn1 where old white ,nell stood in her stall4 ,besides ,nell there were three strong ,normandies in other stalls1 and two stalls that were empty4 ,mr4 ,leonard had a very large barn4 ,there was the main floor1 running through from the two big rolling doors at either end4 ,the great hay mows on both sides1 reached by short ladders1 held some of last year's cutting4 ,under the mows were the stalls for the horses and the stanchions for the cattle4 ,a machine for cutting hay stood on the barn floor4 ,under the barn was a deep1 roomy cellar1 in one corner of which was the sheep pen1 lighted by large windows4 ,near the barn was a tool house1 in which all the tools and machinery were housed during the winter4 ,it pays to have a nice warm barn and a good place to keep the tools from rusting1 said ,uncle ,robert4 ,do you always keep the horses in the barn when they are not in use8 ,oh1 no1 said ,donald4 ,sometimes they run in the pasture along the creek4 ,the cows and sheep are there now4 ,after the timothy and clover are cut we'll put them in those fields4 ,do you keep many cows8 ,we have six cows and two calves1 replied ,donald4 ,father gave one calf to ,frank and one to me4 ,they're beauties4 ,all our cows are ,jerseys4 ,frank and ,i are going to keep ours until they're grown4 ,then if they give as much milk as the other cows do--and ,i'm sure they will--we are going to take it to the creamery and sell it4 ,there's a creamery not far from here4 ,does your father sell the milk there now8 asked ,uncle ,robert4 ,not now1 said ,donald4 ,mother likes to make the butter herself4 ,that's why it is so good1 said ,uncle ,robert4 ,has ,susie a calf too8 ,illustration3 ,the ,barn4 ,susie1 tired of waiting for them to return1 had come to see what they were doing4 ,so she answered for herself4 ,no1 uncle1 she said1 but ,i have the prettiest little lambs you ever saw4 ,they always run to me when they see me coming4 ,please come out to the lot and see them4 ,how many have you8 asked ,uncle ,robert4 ,two1 replied ,susie4 ,they're twins1 and are just alike4 ,their mother is dead4 ,it was cold when they were born4 ,there was snow on the ground4 ,father brought them into the kitchen in a basket to keep them warm4 ,mother and ,i taught them to drink milk1 so father gave them to me4 ,i'm going to keep them always4 ,father likes us to have our own things to take care of1 said ,donald4 ,i think it's ever so much more fun1 don't you1 uncle8 ,yes1 indeed1 said ,uncle ,robert4 ,but you help take care of all the animals1 don't you8 ,oh1 yes1 replied ,donald1 and ,i like them all2 but my calf seems just a little nicer than the rest4 ,i know it isn't any better1 really1 but ,i like to think it is my very own4 ,they stopped to watch the pigeons circling about the pigeon house4 ,i love to watch the pigeons1 said ,susie4 ,see all the pretty colors in their feathers6 ,illustration ,are they very wild8 asked ,uncle ,robert4 ,oh1 no1 said ,susie1 they're very tame4 ,when we throw grain to them they come down all around us4 ,come and see my pigs6 shouted ,donald1 who had run ahead and was looking into the pen4 ,four white1 fat ,berkshire pigs lay in the straw1 lazily rolling their little eyes toward their friend and feeder4 ,a succession of grunts served for conversation4 ,i put in fresh straw every day1 said ,donald1 so my pigs can keep themselves clean4 ,and they have a patent trough to eat out of4 ,i thought farmers in the ,west let their pigs run in the woods1 said ,uncle ,robert4 ,we had a lot of razorbacks for a while1 but they didn't pay1 said ,donald4 ,our ,berkshires make nice pork4 ,how warm the sun is getting6 said ,uncle ,robert as they turned away from the pigpen4 ,the wind is from the southwest1 said ,donald1 looking at the weather vane on top of the barn4 ,it always gets warmer when the wind is from that direction4 ,uncle1 said ,susie1 before we begin to plant the seeds let's go and see my lambs4 ,you go ahead1 and ,i'll get some salt for the sheep1 said ,donald4 ,they always run to me when they see me coming with a pan4 ,they know what that means4 ,donald soon joined them with the pan of salt4 ,mother says she can't work in the garden until afternoon1 he said1 so we needn't hurry back4 ,as they entered the pasture the sheep were quietly grazing on the slope of the hill1 where the grass was nibbled very short4 ,a few lambs were frisking together at the foot of the hill4 ,see the lambs playing1 uncle1 said ,susie4 ,the two little ones with long tails and black noses are mine4 ,aren't they cunning8 ,they'll see me in a minute4 ,then how they will run6 ,the quick ears of the sheep caught the sound of their voices4 ,they raised their heads4 ,donald held out the pan of salt1 shaking it gently4 ,in a moment one of the flock started slowly toward them4 ,donald stopped under one of the large oak trees that grew on the top of the hill4 ,uncle ,robert and ,susie stood beside him4 ,the old sheep came nearer4 ,one by one the rest of the flock began to follow4 ,the lambs stopped playing4 ,susie held out her hand and called softly1 ,come1 ,sally6 ,come1 ,billy6 ,illustration3 ,feeding the sheep4 ,the two little lambs switched their tails and started up the hill4 ,donald sprinkled a little of the salt on the ground4 ,then the whole flock broke into a run1 and the sheep were soon eagerly licking up the salt as ,donald scattered it about for them4 ,susie's lambs came straight to her side and began to lick her hands and sniff about her dress4 ,they think ,i have something for them1 she said4 ,let me have some salt1 please1 ,donald4 ,filling each of her hands with salt1 she held them out1 and the lambs eagerly licked it from the little round palms4 ,the cows are down by the creek1 uncle1 said ,donald4 ,shall we go to see them8 ,you must see my calf4 ,come on1 cried ,susie1 and began to run as fast as she could go4 ,the little lambs1 always ready for a play1 skipped about her4 ,how merrily ,susie did laugh as they ran ahead and then turned around with their noses to the ground and their tails in the air1 waiting for her to come and catch them6 ,they always want me to play with them1 she said1 quite out of breath1 when ,uncle ,robert and ,donald caught up4 ,what beautiful cows6 exclaimed ,uncle ,robert as the little ,jerseys lifted their shy faces from the grass to look at them4 ,i never saw finer ones4 ,that is my calf1 said ,donald1 pointing it out with much pride1 and that one over there is ,frank's4 ,the only way we can tell them apart is that ,frank's has more black on its face than mine has4 ,illustration3 ,donald's calf4 ,toot-toot-t-o-o-t6 ,the sound came from the house4 ,there's the horn6 exclaimed ,susie4 ,it must be dinner time4 ,so soon8 said ,uncle ,robert4 ,how quickly the morning has gone6 ,i tell you ,i'm hungry1 said ,donald4 ,i didn't think of it before1 but ,i'm almost starving4 ,,chapter ,v4 ,,in ,,the ,,flower ,,garden4 ,in the afternoon they all went into the garden4 ,donald and ,mrs4 ,leonard began at once to set out the tomato plants that had been started in a box4 ,susie and ,uncle ,robert walked about1 planning where the flower seeds should be planted4 ,the verbenas are in this bed1 said ,susie4 ,i had them last year4 ,i wish they would begin to come up4 ,don't you think1 uncle1 it will be nice to have the mignonette in with them8 ,yes1 replied ,uncle ,robert1 but where are your nasturtiums8 ,i haven't any nasturtiums1 said ,susie4 ,i wish ,i had4 ,jennie ,wilson's mother had them last year4 ,they bloomed all summer4 ,we can send for some seeds and get them in time to plant1 said ,uncle ,robert4 ,oh1 thank you1 uncle1 exclaimed ,susie4 ,how nice6 ,i'll save this big bed for nasturtiums1 and the bachelor's buttons can go over there4 ,illustration3 ,poppies ,the nasturtiums would do better by the fence and the porch1 said ,uncle ,robert4 ,they like to climb4 ,all right1 said ,susie2 then we can have this bed for something else4 ,have you any poppies8 asked ,uncle ,robert1 smiling4 ,poppies are my favorite flowers4 ,are they1 uncle8 ,then we'll have poppies in this bed4 ,thank you1 dear1 replied ,uncle ,robert1 taking out his notebook4 ,we'll send for the poppy seeds1 too4 ,i think that finishes the beds1 said ,susie4 ,let me see1 and1 walking down the path1 she pointed out where each kind of flower was to grow4 ,you might draw it now1 said ,uncle ,robert2 then we'll make no mistake4 ,oh1 goody6 cried ,susie4 ,that's what ,i'll do4 ,wait until ,i get a pencil and paper4 ,here is a pencil1 said ,uncle ,robert1 taking one from his pocket1 and perhaps this old envelope will do to draw it on4 ,but ,susie thought not4 ,it's too small1 she said4 ,i'll get a nice piece of paper in a minute4 ,away she ran to the house1 and soon came back with a large sheet of fresh white letter paper in one hand and ,frank's geography in the other4 ,i'm going to draw my garden1 she called to ,donald and her mother1 holding up the paper for them to see4 ,i'll make the paths first1 she said1 laying the paper on the geography1 and taking the pencil from ,uncle ,robert4 ,then ,i can put in the beds afterward4 ,when the paths were drawn1 ,susie named the beds and marked them off on the paper4 ,please write the names for me1 ,uncle ,robert1 she said4 ,i can't spell all the big words4 ,i will write them on this paper1 said ,uncle ,robert1 and when you see how they look you can write them on your plan4 ,oh1 yes1 said ,susie1 that will be the nicest way4 ,see1 mother1 cried ,susie1 running to her1 this is my garden4 ,now ,i know just what is to be in every bed4 ,illustration3 ,susie's garden4 ,where are you going to get poppies8 asked ,donald1 looking at the plan on the paper4 ,uncle ,robert is going to send for the seed1 answered ,susie4 ,he likes poppies best of all the flowers4 ,we are going to have nasturtiums1 too4 ,they are to grow by the porch and the fence4 ,that will be fine1 dear1 said ,mrs4 ,leonard4 ,what a beautiful garden we shall have6 ,i can hardly wait1 cried ,susie1 dancing along the walk4 ,come1 uncle1 let's plant what seeds we have now4 ,do we need to do anything to the ground1 asked ,uncle ,robert1 before the seeds are put in8 ,only rake over the top a little1 said ,susie1 taking up her rake and going to work4 ,it has been spaded4 ,see how light and fine it is underneath6 ,ugh6 ,i wish the old worms would keep out6 ,don't be too hard on the worms1 said ,uncle ,robert4 ,they are your best helpers4 ,i don't see how that is1 uncle1 said ,susie1 looking up in surprise4 ,you just said the soil was light and fine1 said ,uncle ,robert4 ,don't you know you have to thank the worms for keeping it so8 ,are you sure1 uncle8 asked ,susie4 ,i thought the worms ate the plants4 ,the earthworms never eat the plants1 said ,uncle ,robert4 ,they eat the soil1 and so keep it worked over4 ,it is the cutworm that eats the plants4 ,just then ,donald came over from the vegetable garden4 ,why1 you've only just begun1 he said4 ,we're all through4 ,don't those tomato plants look nice8 ,well1 said ,susie1 you didn't draw your garden4 ,that took a long time1 didn't it1 uncle8 ,you rake those beds for me1 ,don1 while ,i put the seeds in4 ,i'd just as soon1 said ,donald1 taking the rake4 ,what goes here8 ,mignonette1 said ,susie4 ,when any one wants to know about my garden now1 they can look at the drawing4 ,uncle ,robert smiled4 ,what makes you think you'll have mignonette there8 he asked1 as ,susie marked a little furrow with a stick in the soft1 warm soil4 ,why1 these are mignonette seeds1 she replied4 ,i gathered them myself4 ,don't you think they'll grow1 uncle8 ,certainly ,i do1 replied ,uncle ,robert4 ,it would be a pretty dead seed1 said ,donald1 that wouldn't grow in this soil4 ,are seeds alive8 asked ,uncle ,robert1 smiling4 ,why1 ,i--,i don't know1 said ,donald1 looking puzzled4 ,i never thought about it4 ,i just said that4 ,they don't look like it1 that's a fact1 but they surely wouldn't grow if they were dead1 would they8 ,do all seeds grow in the same way8 asked ,uncle ,robert4 ,i never thought about it1 said ,donald4 ,neither did ,i1 said ,susie4 ,i just know if ,i plant mignonette1 mignonette will grow2 and if ,i plant sweet peas1 sweet peas will grow4 ,that's all ,i ever thought about it4 ,would you like to know8 asked ,uncle ,robert4 ,oh1 yes1 said ,susie4 ,how can we8 asked ,donald4 ,the seeds are in the ground1 and we can't see them4 ,if ,susie is willing to dig up one of her sweet peas1 said ,uncle ,robert1 perhaps it will tell us what it has been doing since she planted it last week4 ,oh1 yes1 said ,susie4 ,see if you can find one1 ,don4 ,i put lots in4 ,down on their knees went ,susie and ,donald1 and began digging in the soil4 ,here is one1 said ,donald1 just ready to come up1 and another close to it4 ,the tip of it must have been through4 ,see1 it is green4 ,wouldn't it be green in the ground8 asked ,susie1 looking closely at the tiny plant4 ,why1 no1 said ,donald4 ,things are never green when they're covered up4 ,it's light that makes things green4 ,don't you know how yellow the grass gets if a board lies on it1 and what yellow stalks the potatoes have when they sprout in the cellar8 ,it must be the light that makes them green4 ,oh1 yes1 said ,susie4 ,but see how big that pea is6 ,it's about twice as big as it was when ,i planted it4 ,illustration3 ,sprouting pea4 ,see1 said ,donald1 the roots grow from the same place that the stem does4 ,i should think it would be better if one came from one side of the pea1 and one from the other4 ,what becomes of the rest of the seed8 asked ,uncle ,robert4 ,i don't know1 said ,susie4 ,is it of any use8 ,it is of the greatest use1 replied ,uncle ,robert4 ,the little pea plant couldn't live without it4 ,it is its food that the mother sweet pea gathered last summer from the soil and air1 and stored away in the little round ball for her baby to feed on until it should be big enough to get its own food4 ,do you really mean1 uncle1 cried ,susie1 with shining eyes1 that the sweet peas ,i have planted in that bed are the children of those ,i had last year8 ,why not8 asked ,uncle ,robert1 with a smile4 ,i never thought of it before1 said ,susie1 looking at the tiny plant in her hand2 but ,i like it4 ,it seems just like a family4 ,and that's what it is1 said ,uncle ,robert4 ,don't you think this baby had better go back to bed8 said ,susie1 making a deep hole in the ground4 ,wait a moment1 ,susie1 said ,uncle ,robert4 ,suppose we take it for a visit to the beans1 and see if they grow like it4 ,so they went to the vegetable garden1 where they found a great many plants1 each with two strong1 thick leaves sticking through the soil4 ,some were quite green and showed a tiny shoot between them4 ,others were yellow1 with only the tips turned green4 ,dig one up1 ,don1 said ,susie1 and let's see if it is like the baby pea4 ,donald pulled one up1 but no bean was to be seen4 ,the stem grew straight into the ground1 ending with a little bunch of roots4 ,where's the bean8 asked ,susie4 ,these two leaves must be the bean1 said ,donald4 ,don't they look like it8 ,he took a bean from his pocket and held it close to the little plant4 ,well1 ,i never6 cried ,susie4 ,if those two leaves aren't just the bean split open6 ,are they any good that way1 uncle8 ,yes1 indeed1 said ,uncle ,robert1 smiling4 ,they feed the little bean just as the pea does4 ,but they do even more4 ,what do you think they will do when the sun goes down and the air gets cool8 ,illustration3 ,sprouting bean4 ,oh1 ,i know4 said ,donald4 ,i've seen them lots of times4 ,they just shut together tight4 ,and that keeps the little bud you see in there as warm as you are in your bed4 ,isn't that wonderful8 said ,susie4 ,why1 uncle1 it's just as if they could think6 ,the leaves drop off after a while1 said ,donald4 ,i often see them lying on the ground4 ,yes1 said ,uncle ,robert4 ,when the plant is strong enough to take care of itself1 their work is done4 ,are there any other plants that make leaves out of the seeds1 uncle8 asked ,donald4 ,oh8 yes1 replied ,uncle ,robert4 ,squashes and pumpkins do1 and many others4 ,some have more perfect leaves than these4 ,let us look at the morning glories by the porch4 ,illustration3 ,morning glory4 ,they come up every year by themselves1 said ,susie4 ,she ran to her garden1 saying1 ,i'm going to put this pea-baby to bed again4 ,do you think it will grow1 uncle8 ,it may1 but it is not good for it to be out of bed too long4 ,i'll put a stick by it1 said ,susie1 so ,i can watch it4 ,good-by1 baby1 giving the ground a little pat2 go to sleep4 ,then she ran after ,uncle ,robert and ,donald4 ,how thick the morning glories are6 said ,donald4 ,some of them have several leaves on1 but here is one with only two4 ,they don't look as the bean leaves do1 said ,susie4 ,the beans are so thick6 ,these have real leaves4 ,yes1 said ,uncle ,robert1 and if you could see them in the seed1 you would see these leaves all curled up in their hard coat4 ,this one is just putting its head through the ground1 said ,susie1 and it has part of the shell on it yet4 ,it looks as the little chickens do sometimes1 laughed ,donald1 when they come out of the nest with a piece of the shell sticking to their backs4 ,that hard shell is a great protection to the tender plant as it works its way up through the soil1 said ,uncle ,robert4 ,if these seed leaves are real leaves1 uncle1 asked ,donald1 what feeds the baby morning glories8 ,there is plenty of food in the seed around the leaves1 said ,uncle ,robert4 ,when the seed gets moist in the ground1 it becomes so soft that the plant can use it4 ,have you ever noticed when you were eating corn the little hard bud that grows in each grain close to the cob8 ,yes1 uncle1 answered ,susie4 ,that is the sweetest part of the corn4 ,that is the part1 said ,uncle ,robert1 from which the new plant grows1 and all the rest of the grain is the food stored up for it4 ,i wish we had some corn1 said ,susie1 so we could see it4 ,i'll go and get some1 said ,donald4 ,oh1 do1 ,don1 said ,susie1 and while he's gone1 ,uncle ,robert1 ,i can plant the rest of my seeds4 ,i have only a few left4 ,so ,donald ran to the cornfield and ,susie went to the garden4 ,when he came back she had finished1 and they joined ,uncle ,robert on the piazza4 ,the corn grows out of the side of the seed1 said ,donald4 ,see what a big root it has for such a little plant6 ,illustration3 ,sprouting corn4 ,how pretty those leaves are6 said ,susie4 ,they look like two little green feathers4 ,some one else had the same thought1 ,susie1 said ,uncle ,robert4 ,did you ever hear the story the poet ,longfellow tells about how the corn came to the ,indians8 ,you know it is called ',indian corn4' ,no1 uncle1 said ,susie4 ,do tell us4 ,so as they sat beside him on the piazza4 ,uncle ,robert told the story of ,hiawatha and ,mondamin4 ,hiawatha was a brave young ,indian chief1 began ,uncle ,robert1 who wanted to help his people4 ,he knew that there were times when they had no food4 ,in the winter the birds flew away4 ,the 'big sea water1' as they called the great lake1 was frozen over1 and they could catch no fish4 ,there were no wild berries in the woods4 ',master of ,life1' he cried1'must our lives depend on these things8' ,he was very unhappy4 ,he could not eat4 ,he lay in his wigwam1 fasting and praying for some good to come to his people4 ,one evening as he lay watching the setting sun he saw a youth coming toward him4 ,his dress was green and yellow1 and over his yellow hair he wore a bright green plume4 ',the ,master of ,life has sent me1' said the youth4 ',i am ,mondamin4 ,it is only by hard labor ,hiawatha1 that you can gain the answer to your prayer4 ,rise now1 and wrestle with me4' ,hiawatha was weak from fasting1 but he did as ,mondamin commanded4 ,until the sun had set they wrestled together4 ,then ,mondamin went away as silently as he had come4 ,a second time he came1 and a third4 ,then he said3 ',you have fought bravely1 ,hiawatha4 ,i shall come once more4 ,you will conquer me4 ,then you must take off my dress of green and yellow and my nodding plumes4 ,make a bed in the soft warm earth for me to lie in4 ,let nothing come to disturb me as ,i slumber4 ,only let the sunshine and the rain fall upon me4 ,you must watch beside me1 ,hiawatha1 until my sleep is over4' ,then he was gone4 ,when they wrestled the next night it was as ,mondamin had said4 ,he was conquered4 ,then1 day after day1 ,hiawatha came and watched1 ',till at length a small green feather ,from the earth shot slowly upward4' ,there it is1 whispered ,susie4 ,sh6 said ,donald4 ,then another and another1 continued ,uncle ,robert1 and before long the corn was waving its long1 green foliage in the sunshine4 ',it is ,mondamin6' cried ,hiawatha1'the friend of man1 ,mondamin6' ,what a lovely story6 cried ,susie as ,uncle ,robert finished4 ,i wish ,frank could have heard it4 ,we'll find it in your mother's book of ,longfellow's poems and let ,frank read it1 said ,uncle ,robert4 ,let's tell him about the seeds first1 said ,donald4 ,he'll like it better then4 ,illustration3 ,a stalk of corn4 ,,chapter ,,vi4 ,,sunlight ,,and ,,shadow4 ,it was a busy time on the farm4 ,only when the day's work was over and they were gathered in the sitting-room was there time for the long talks with ,uncle ,robert that they all enjoyed so much4 ,it's wonderful1 said ,mr4 ,leonard one evening1 looking up from his paper1 how fast the corn is growing4 ,even the late planting is coming on4 ,that's because the weather is so warm1 said ,donald4 ,i wonder what makes it warm8 said ,uncle ,robert4 ,why1 ,uncle ,robert1 exclaimed ,susie1 it's spring6 ,that's what makes it warm4 ,but what makes it spring1 little girl8 asked ,uncle ,robert4 ,why1 it is always spring in ,may1 said ,susie4 ,i know of a country where it is spring in ,september1 replied ,uncle ,robert4 ,how can it be8 asked ,susie4 ,i thought springtime always came in ,may4 ,what makes us know that it is spring8 asked ,uncle ,robert4 ,oh1 it gets warmer all the time4 ,the birds come1 things begin to grow1 and the flowers bloom4 ,but what makes all this happen just now8 ,it's the sun1 answered ,donald from the floor1 where he was playing with his great ,st4 ,bernard dog1 ,barri4 ,you know it rises earlier and sets later every day now than it did a while ago4 ,it's hotter too4 ,it goes higher at noon1 said ,frank4 ,in the middle of summer it is almost straight over our heads1 and in the winter it seems ever so much farther to the south4 ,i've often noticed that4 ,so have ,i1 said ,donald4 ,and in the winter the shadows are longer than they are in summer4 ,it must be because the sun isn't so high up4 ,aren't shadows funny8 said ,susie4 ,one day when ,i was coming in to dinner1 just for fun ,i tried to walk on my shadow1 and ,i could step on my head4 ,i've done that lots of times1 said ,donald4 ,but it's a strange thing4 ,sometimes ,i can step clear over my head--,i mean in the shadow--and then again ,i have to step on it4 ,and when you jump1 said ,susie1 it spoils it4 ,the shadow always jumps too4 ,what kind of weather was it when you had to jump to it8 asked ,uncle ,robert4 ,i don't remember1 said ,donald4 ,would the weather make any difference8 ,i remember1 said ,susie1 because one time when ,i was jumping that way ,i fell down and was almost buried in the snow4 ,then it was winter1 wasn't it8 asked ,uncle ,robert4 ,it must have been1 said ,frank4 ,illustration3 ,shadow stick4 ,and since you told us that the shadows at noon tell why it is warmer in summer than in winter ,i've been watching them4 ,they get shorter all the time4 ,how would you like to measure the shadows every day1 said ,uncle ,robert1 and see if you can find out when they are shortest and when they are longest8 ,how can we8 asked ,susie4 ,shadows are so queer4 ,yes1 said ,uncle ,robert1 shadows are queer1 but1 if we take one that doesn't jump as yours does1 don't you think we can measure it8 ,of course we can1 said ,frank4 ,we can use the house4 ,that always stands still4 ,the house might do1 said ,uncle ,robert2 but wouldn't it be better to have a shadow stick8 ,where can we get one8 asked ,donald4 ,what is it made of8 asked ,frank4 ,it is like this1 said ,uncle ,robert1 taking paper and pencil from his pocket4 ,there is one long piece of board1 and one short one nailed to the end--so1 drawing it on the paper4 ,oh1 that's easy enough made1 said ,donald4 ,we can do it ourselves right here in the tool house4 ,let's make it to-morrow1 ,don1 said ,frank4 ,it must be set up some place with the upright end turned toward the south1 so that just at noon the shadow of the short piece may fall straight on the board4 ,by drawing a line across the board at the top of the shadow and marking the date on it1 we can tell how the length of the shadow changes4 ,uncle1 asked ,donald1 when it is winter here1 is it summer in some other part of the world8 ,yes1 was the reply1 and now that our summer is coming1 the people there are beginning to have winter4 ,then1 said ,frank1 when it gets cooler here in the fall it is growing warmer there1 and that would make their spring come in ,september1 wouldn't it8 ,do you see1 ,susie8 ,illustration3 ,eskimo scene4 ,yes1 answered ,susie1 but it seems all mixed up4 ,i thought it was the same as it is here all over the world4 ,oh1 ,i didn't1 said ,donald4 ,i've read about countries where it is summer all the time1 and is so hot that the people don't do anything but lie under the trees and sleep4 ,and there are other countries where it is winter all the time1 and the people dress in furs and make their houses of snow and ice4 ,i read all about it in a book once1 but it didn't tell why it was so4 ,i knew1 of course1 the sun had something to do with it4 ,why1 you know1 ,don1 said ,frank1 we learned all that in our geography at school4 ,yes1 said ,donald1 but ,i never thought about that in the geography as meaning any real country4 ,what did you think it meant8 asked ,uncle ,robert4 ,oh1 said ,donald1 just a lesson in the book4 ,well1 said ,frank1 ,i always thought it was some country1 but ,i never knew where4 ,i didn't think much about it after ,i said the lesson4 ,i should think not1 said ,uncle ,robert1 not sorry that the teacher had gone away and the school had been closed4 ,i wish when books tell things they'd tell why they're so1 said ,frank4 ,perhaps if we think about these things1 said ,uncle ,robert1 we may be able to answer some of the 'whys' for ourselves4 ,we can tell by the thermometer just how warm it is every day1 said ,susie1 but it won't tell us why4 ,the shadow stick may help us there1 said ,uncle ,robert4 ,i am afraid ,i shall forget1 said ,donald4 ,i have some little notebooks in my trunk1 said ,uncle ,robert4 ,suppose ,i give you each one and let you write down what the thermometer and the shadow stick say every day4 ,what fun that'll be6 cried ,susie4 ,when may we begin8 ,to-morrow morning1 if you like1 replied her uncle4 ,i will get the books for you now4 ,he went away to his room1 and soon returned with the notebooks4 ,i'll tell you1 uncle1 said ,frank as he thanked ,uncle ,robert for his book1 how would it do for each of us to look at the thermometer at a different time of the day8 ,the very thing6 replied ,uncle ,robert1 well pleased4 ,you are always up early1 ,frank1 so suppose you look at six in the morning1 ,susie at twelve o'clock1 and ,donald at six in the evening4 ,how will that do8 ,then we shall have the record for the whole day4 ,i think it will be such fun6 said ,susie4 ,i wonder if our books will be very different4 ,what makes you think they will be different8 asked ,uncle ,robert4 ,it's always hotter at noon than it is at night or in the morning1 said ,susie4 ,do you know1 said ,uncle ,robert1 there are places all over the ,united ,states where such records are kept8 ,they are published1 and ,i am to have them sent to me every week4 ,i wonder if ours will be like them1 said ,donald1 turning over the pages of his notebook4 ,even if they should be different4 said ,uncle ,robert1 they may be just as true4 ,we'll get up early and start the shadow stick the first thing in the morning1 said ,frank1 so as to have it ready by noon4 ,how do you know when it is noon8 asked ,uncle ,robert4 ,we look at the clock1 said ,susie4 ,but noon by the clock is not always noon by the sun1 replied ,uncle ,robert4 ,how can that be8 asked ,donald4 ,it is noon somewhere on the globe every minute of the twenty-four hours1 said ,uncle ,robert4 ,the sun is always setting and always rising somewhere4 ,the children were puzzled4 ,i don't see how that is1 said ,donald4 ,let us see if we can find out1 said ,uncle ,robert4 ,frank1 you stand at the east end of the room1 ,donald at the west1 and ,susie in the middle4 ,now1 we'll play that ,frank is in ,new ,york1 ,susie here at home in ,illinois1 and ,donald in ,denver4 ,i'll take the lamp and be the sun4 ,you are shadow sticks1 you know4 ,now watch the shadows1 and see when they point directly north4 ,uncle ,robert took the lamp and walked slowly from the east side of the room4 ,my shadow points north1 said ,frank as ,uncle ,robert passed him4 ,now mine does1 said ,susie4 ,and mine last of all1 said ,donald4 ,uncle ,robert took out his watch4 ,it was ten minutes past eight4 ,that is ,susie's time1 he said4 ,would it be the same in ,new ,york1 ,frank8 ,i think it would be past that1 said ,frank1 but ,i don't know how much4 ,it is ten minutes past nine by the watch in ,new ,york1 said ,uncle ,robert4 ,when would it be that time in ,denver8 asked ,donald4 ,in an hour by the watch1 said ,uncle ,robert1 but it would not be the same by the sun4 ,then the watches don't tell the true time1 do they8 said ,frank4 ,the sun's shadows give us the true time1 said ,uncle ,robert4 ,we will study the shadows1 and by and by may learn how the watches and clocks are regulated4 ,but how do you think people told the time before they had clocks8 ,it must have been by the sun1 replied ,frank4 ,i can tell by the sun when it is noon1 said ,donald1 but ,i don't see how any one can tell any other hour that way4 ,how do you know when it is noon8 ,why1 the sun is highest at noon4 said ,donald4 and the shadows point straight toward the north4 ,early in the morning they point to the west1 said ,frank1 and in the evening they point to the east4 ,the people who lived in the world many hundred years ago observed the same thing1 said ,uncle ,robert4 ,there was nothing so strange to them as the rising and setting of the sun4 ,they loved the light that came with it4 ,they feared the darkness that followed its going away4 ,they told many interesting stories to explain this continued appearance and disappearance4 ,some thought the sun was a king riding through the sky in a golden chariot4 ,others looked upon it as a god and worshiped it4 ,they soon learned that when it went away it was sure to come again1 and as they saw how regularly it moved1 they felt there must be some power back of it to guide it4 ,through this they were led to a belief in a ,being that controlled all things4 ,they watched the shadows1 too1 and saw them change just as you see them every day4 ,they learned that the shadow is shortest when the day is half gone1 and they called that time midday4 ,so1 by studying the length and direction of the shadows1 they soon became able to judge the time of day4 ,then some one thought to set up a rod and mark the places where the shadow fell at sunrise1 at sunset1 and at midday4 ,the space in between was divided for the hours4 ,this was called a sun dial and was the first instrument ever made for telling time4 ,when was the first one made8 asked ,frank4 ,that is not known1 replied ,uncle ,robert1 but we read in the ,bible of the sun dial of ,king ,ahaz1 who lived about eight hundred years before the time of ,christ4 ,that is the first record we have of one4 ,how was it made8 asked ,donald4 ,i do not know how the one ,king ,ahaz used was made1 said ,uncle ,robert1 but ,i can show you how one looked that ,i saw in an old garden in ,england4 ,this1 drawing a half circle1 is the dial on which the hours were marked4 ,around this dial there was a border1 much cracked1 and crumbling away1 but ,i could read the words1 ',the sun guides me1 the shadow you4' ,the rod1 or gnomon1 as it is sometimes called1 stood just halfway between the ends4 ,where would the noon shadow fall1 ,susie8 ,illustration ,in the middle1 wouldn't it8 answered ,susie4 ,and the morning shadow would fall on the west and the evening shadow on the east side1 said ,frank4 ,now we'll put in the shadow stick1 said ,uncle ,robert1 drawing a triangle on the paper4 ,why don't you make it stand up straight8 asked ,donald4 ,the shadow does not tell the truth1 said ,uncle ,robert1 unless it points in the same way that the north pole does1 and that1 we know1 points to the north star4 ,i will explain this some other time4 ,couldn't we make a sun dial8 asked ,donald4 ,i don't believe it would be very hard4 ,you could make one easily1 answered ,uncle ,robert4 ,but let's have the shadow stick first1 said ,frank4 ,susie went to the window and looked out at the clear star-lighted sky4 ,uncle1 she said1 the stars all look alike to me1 only some are little and some are big4 ,how can people know them by their names8 ,just as anything else is known1 dear1 replied ,uncle ,robert1 by close and careful study4 ,i wish we could study the stars1 said ,frank4 ,we will some time1 replied ,uncle ,robert4 ,come out on the piazza now1 and ,i will show you the north star4 ,that will be a good beginning4 ,,chapter ,,vii4 ,,the ,,barometer4 ,one day when it was ,donald's turn to go for the mail he found among ,uncle ,robert's letters a small paper4 ,on the wrapper he read ,united ,states ,weather ,report4 ,it had come4 ,there was already quite a line of figures in each of their notebooks4 ,now they could see what this other record was like4 ,as he left the post office he stopped to look at the old thermometer beside the door4 ,then he mounted ,nell and rode down the village street and out into the pleasant country road4 ,uncle ,robert was waiting for him on the porch1 and as ,donald rode away to the barn1 after giving him the mail1 he heard him say3 ,here1 ,frank1 is the ,weather ,report4 ,open it and look at it while ,i read my letters4 ,donald took off the saddle and gave the horse her supper4 ,then he hurried back to see what ,frank had found on the inside of the important-looking wrapper4 ,it proved to be a map with queer1 crooked lines all over it1 but it did not look at all interesting4 ,here it says temperature1 said ,frank1 pointing to a list of figures in the corner4 ,perhaps this is what we want4 ,i don't see any numbers there like mine1 said ,donald1 taking his notebook from his pocket4 ,let me help you1 said ,uncle ,robert1 laying aside his letters and coming to where they sat on the steps4 ,they made room for him1 and1 as he took the map1 he explained3 ,this1 you see1 is a map of the ,united ,states4 ,these dotted lines tell about the temperature4 ,for instance1 look at this one which is marked fifty degrees4 ,at every place in the country that is touched by this line on the map the thermometer stood at fifty degrees at the time the map was made4 ,illustration3 ,united ,states weather map4 ,see1 said ,susie1 how crooked the line is4 ,why isn't it straight1 uncle8 ,because1 was the reply1 as ,i told you1 it goes wherever the temperature was fifty degrees4 ,you remember1 the first day we had our thermometer1 we found that there are many things which affect the temperature4 ,at some places along this line there are prairies1 at others forests1 at others lakes1 and here1 pointing to the map1 there are high mountains4 ,all of these things affect the temperature1 and that1 of course1 changes the direction of the line4 ,you say ,chicago is the nearest station to us1 uncle1 said ,frank1 looking down the temperature column4 ,my record for that day is not so very different from the one given here for ,chicago4 ,which shows that yours is probably as nearly correct as this is1 said ,uncle ,robert1 with an encouraging smile4 ,but ,i haven't one number in my book like that1 said ,susie1 looking disappointed4 ,i don't see why4 ,illustration3 ,susie's notebook ,i do1 replied ,uncle ,robert4 ,you make your record at noon1 and of course1 it is warmer then4 ,that is what your book says1 does it not8 ,yes1 said ,susie1 every number in my book is more than that one4 ,that is right1 was the reply1 for this record was made at eight o'clock in the morning1 which is nearer ,frank's hour than it is yours4 ,so we would expect his to be nearer like this than yours1 wouldn't we8 ,it isn't like mine either1 said ,donald4 ,we may have one some time that will be more like yours1 said ,uncle ,robert1 for these records are made at eight in the evening as well as in the morning4 ,uncle1 said ,frank1 looking closely at the map1 here it says ',high1' and there it says ',low4' ,what does that mean8 ,it means1 said ,uncle ,robert1 that here there is a low barometer1 and there the barometer is high4 ,barometer1 said ,donald4 ,what is a barometer1 uncle8 ,is it like a thermometer8 ,well1 not exactly1 was the reply4 ,with the thermometer1 you know1 we tell the temperature of the air1 and with the barometer we tell how heavy it is4 ,how heavy the air is6 exclaimed ,susie4 ,how funny6 ,why1 uncle1 air doesn't weigh anything1 does it8 ,more than you think1 little girl1 said ,uncle ,robert1 smiling4 ,but perhaps we can prove whether it does or not4 ,frank1 will you get a pail of water8 ,donald1 see if you can find a cork some place2 and ,susie1 run in and get a tumbler4 ,when all was ready ,uncle ,robert asked ,frank to fill the pan with water1 and ,donald to put the cork into it4 ,illustration3 ,experiment ,no4 #a4 ,there1 said ,donald1 as the cork floated about on the pan of water4 ,but ,i want the cork on the bottom of the pan1 said ,uncle ,robert1 not on the top of the water4 ,it won't stay there1 declared ,donald1 pushing it into the water again and again with his finger4 ,it is too light4 ,corks always float4 ,how can we make it go to the bottom8 ,no one could tell4 ,the children looked puzzled4 ,let us see what this will do1 and1 taking the glass from ,susie's hand1 ,uncle ,robert turned it over the cork1 pressed it down into the water as far as it would go1 and held it there4 ,looking through the glass1 they could see the cork lying on the bottom of the pan4 ,why1 ,uncle ,robert6 exclaimed ,susie1 what--how-- ,it's the glass that does it1 declared ,donald4 ,but the glass doesn't touch the cork1 objected his uncle4 ,there's air in the glass1 said ,frank1 who had been looking at it quietly as the others talked4 ,that is what presses it down4 ,if it's air1 said ,donald1 why didn't it go down before the glass was put over it8 ,there was just as much air about it then1 and more1 too4 ,let go of the glass1 uncle1 said ,frank1 and see what it will do4 ,uncle ,robert did so1 and the glass instantly turned over1 while a big bubble of air escaped through the water4 ,there1 said ,frank1 smiling1 ,i told you so6 ,then air only presses on things when there is something like the glass to hold it down4 ,is that so1 uncle8 asked ,donald4 ,let us see1 was the reply4 ,illustration3 ,air ,pressure4 ,experiment ,no4 #b4 ,filling the glass with water1 he placed a piece of paper over it1 and quickly turned it upside down4 ,not a drop of water fell from the glass4 ,the paper1 now beneath the water1 stayed there as though glued4 ,uncle1 said ,frank1 is it truly the air that holds the paper on and keeps the water in the glass8 ,if it presses that way everywhere1 why don't we feel it8 ,it is because it presses equally in every direction1 replied ,uncle ,robert4 ,put your hand in this pail of water4 ,do you feel it pressing on your hand8 ,no1 said ,frank4 ,place it lower in the water4 ,does it feel any heavier now8 ,not at all1 answered ,frank4 ,but you know that the water is heavy4 ,lift the pail1 ,donald4 ,it is heavy1 said ,donald1 setting it down4 ,i don't see why ,frank didn't feel a little of the weight of it when his hand was under all the water4 ,it is this way1 explained ,uncle ,robert4 ,the water pressed on his hand from below as much as from above1 and the same on both sides4 ,when you lifted it you felt its weight pressing downward only4 ,now it is just so with the air4 ,it presses with such equal pressure that we do not realize its weight4 ,it is only when it presses harder from one direction than from another that we feel it4 ,that's when the wind blows1 isn't it1 uncle8 asked ,donald4 ,yes1 my boy1 was the reply4 ,you can see how it is out among the trees now4 ,but1 uncle1 said ,donald1 how can the air be weighed if it presses the same in all directions8 ,it was only when ,i lifted the whole pail of water that ,i felt how heavy it was4 ,the air can't be weighed if it presses up just as much as it does down4 ,but if in some way it could be shut off so that it would only press in one direction8 ,it might be1 answered ,donald1 but ,i don't see how4 ,uncle ,robert told ,susie to put the glass in the water so that it would all be below the surface1 and1 without taking it from the water1 to turn it upside down4 ,she did so1 and then began to lift it slowly out of the water4 ,see1 cried ,susie1 the water comes with it4 ,the glass is full4 ,could ,i lift it clear out that way8 ,try it1 said ,uncle ,robert1 smiling4 ,but no2 when the edge of the glass came out of the water in the pail1 down went the water with a splash4 ,i see how it is1 said ,frank1 who had watched it closely4 ,there wasn't any air in the glass to keep the water out1 as there was when we turned it over the cork1 so the water stayed in it4 ,but what made it come up out of the pail8 asked ,donald4 ,there wasn't any air under it to press it up4 ,would the air pressing on the water around the glass make it do so1 uncle8 asked ,frank1 placing the glass in the water and raising it as ,susie had done4 ,it seems as if it might be that4 ,that is what it is1 replied his uncle4 ,the air pressing on the water in the pail forces it into the glass1 where there is nothing to keep it from rising4 ,if the glass was longer would the water stay in it just the same8 asked ,donald4 ,yes1 was the reply4 ,if there was no air in the glass it would have to be very many times as long as this glass is to hold the water that would rise if it had a chance4 ,but come1 let us sit down on the steps again1 and ,i will tell you about it4 ,when they were settled he continued3 ,over two hundred and fifty years ago there lived a man named ,galileo1 who learned a great many wonderful things by studying the stars and doing just such things as we have been doing4 ,it was he who made the first thermometer4 ,but there was one question that he could not answer4 ,he found that in a hollow glass tube1 closed at one end1 water would rise thirty-four feet high1 but no higher4 ,he could not tell why4 ,a pupil of his thought he would try the same thing with the heaviest liquid known---- ,that was mercury1 wasn't it1 uncle8 interrupted ,donald4 ,yes2 he used mercury1 and found that it rose in the tube just thirty inches4 ,he knew that the mercury was thirteen and six-tenths times as heavy as the water1 so he felt sure that it was the pressure of the air that made them both rise in the tube1 for thirty-four feet is just thirteen and six-tenths times thirty inches4 ,but they wanted to see if it was really the air1 so they took the tube up on a high mountain4 ,what difference would that make8 asked ,susie4 ,look at the woodpile out there1 said her uncle4 ,where do you think the weight of the wood would be the greater8 ,on the ground or halfway to the top8 ,on the ground1 of course1 answered ,susie4 ,well1 they found it was the same with the air4 ,as they went up the mountain the mercury in the tube fell4 ,that showed that the weight on it was less1 didn't it1 uncle8 said ,frank4 ,i think that was a very wonderful discovery1 don't you8 ,it was1 indeed1 replied ,uncle ,robert1 and that is how the first barometer was made4 ,illustration3 ,barometer4 ,is that what a barometer is8 asked ,donald4 ,yes1 was the reply1 simply a glass tube about thirty-three or thirty-four inches long1 closed at the top1 and filled with mercury4 ,it is then placed in a small open cup1 called the cistern1 into which the mercury flows until the air pressing on it there will let it fall no farther4 ,does it always stay at the same height in the tube8 asked ,donald4 ,oh1 no1 his uncle answered4 ,some days the air is heavier than others1 and so presses harder on the mercury4 ,that would make it rise1 wouldn't it8 asked ,susie4 ,yes1 dear4 ,so1 uncle1 said ,frank1 taking up the ,weather ,report1 where it says ',high' here1 it means that the air is heavier than where it says ',low4' ,is that it8 ,that's right1 replied ,uncle ,robert2 and when the barometer is low we know there will be a storm4 ,well--and ,donald stood up and stretched himself--,i wish ,i could see a barometer4 ,you shall1 said ,uncle ,robert ,i will send for one4 ,you may carry the letter to the post office to-morrow when you go for the mail4 ,,chapter ,,viii4 ,a ,,walk ,,in ,,the ,,woods4 ,it was a beautiful ,sunday afternoon4 ,the sun had marked its shortest shadows4 ,they were now pointing toward the northeast4 ,the family had returned from the little village church4 ,dinner was over1 and they had all gone into the cool1 shady piazza4 ,mrs4 ,leonard and ,susie had settled themselves cozily in one corner and were reading together4 ,mr4 ,leonard was nodding over the pages of his weekly newspaper4 ,frank1 stretched out on the settee1 was absorbed in a new book1 while not far away ,donald lay under the spreading branches of a spruce tree with ,barri by his side4 ,uncle ,robert stood gazing at the green woods1 which looked so cool and inviting4 ',the groves were ,god's first temples1' he said to himself1 and then1 turning to the others1 asked1 ,who wants to go for a walk8 ,i do1 said ,frank1 springing up4 ,come on1 ,don4 ,don-ald6 he called1 we're going for a walk4 ,you'd better come with us1 said ,uncle ,robert to ,mrs4 ,leonard4 ,i'll get your hat1 mother1 cried ,susie eagerly1 running into the house4 ,shall we go to the cornfield8 asked ,mr4 ,leonard1 picking up his straw hat4 ,i think it would be cooler in the woods1 said ,mrs4 ,leonard4 ,oh1 yes1 said ,donald1 let's go up the creek to the pond4 ,the country was in the full glory of early summer4 ,just beyond the rich green of the great cornfield could be seen the peaceful river4 ,the yellowing grain on the upland waved gently in the breeze4 ,under the wide-spreading oak trees in the pasture the cows were lazily chewing their cuds4 ,a feeling of quiet pleasure filled the air4 ,i planted all these trees1 said ,mr4 ,leonard as they walked under the maples that grew on either side of the road4 ,it is wonderful how they have grown4 ,they were like little sticks when ,i set them out4 ,the one at the end of the row1 said ,mrs4 ,leonard1 was planted the day ,frank was born4 ,it is the largest of them all1 said ,frank4 ,that's because it was planted first1 said ,susie4 ,i have a tree1 too1 uncle4 ,so have ,i1 said ,donald4 ,it is the spruce in the front yard4 ,we call them our birthday trees1 said ,susie4 ,mine is the elm by the corner of the porch4 ,that is a very nice custom1 said ,uncle ,robert4 ,but the trees grow faster than you do4 ,they don't have anything to do but grow1 said ,donald4 ,when they reached the bridge they paused to look up and down the creek valley4 ,through the trees they caught glimpses of the shining river and the waving corn4 ,the creek1 a little stream1 flowed between the two gentle slopes that formed its valley4 ,there's a gate under this bridge1 uncle1 said ,donald1 to keep the cows from going down the creek to the cornfield4 ,in the fall1 after the corn is cut1 we open it1 and let them go to the river4 ,how pleasant it is in here6 said ,uncle ,robert as they walked farther into the wood4 ,just see how damp the ground is under these dead leaves6 said ,susie as she pushed them back from a little violet that she was trying to pick with a long stem4 ,poor little flowers6 ,how do they ever get through all these leaves8 ,it would be so much easier for them if it was just green grass4 ,illustration3 ,the bridge4 ,but then there wouldn't be any flowers1 said ,mr4 ,leonard1 or at least they would be very different4 ,illustration3 ,,hickory ,,oak ,,willow ,,butter-,,nut ,,maple ,,walnut 7leaves7 ,it's the leaves that make the soil so rich1 said ,frank1 digging into the ground with a stick4 ,see how they are mixed all through it6 ,do you know the names of all these trees8 asked ,uncle ,robert4 ,i do1 said ,frank4 ,i can tell every tree in the wood4 ,how8 asked ,uncle ,robert4 ,by the leaves is the easiest way1 said ,frank1 but ,i know some trees by the bark4 ,i can tell them by the leaves1 said ,donald4 ,try me4 ,so as ,uncle ,robert pointed to them ,donald called them all by name4 ,there were oaks and maples1 hickories1 walnuts1 and butternuts1 and close to the creek the overhanging willows4 ,can you tell a tree by its shape when you look at it from a distance8 asked ,uncle ,robert4 ,i can tell the willows and poplars1 said ,frank1 and maples1 too4 ,the trees in the pasture have a different shape from those in the woods1 said ,uncle ,robert4 ,i mean trees of the same kind4 ,how do you explain that8 ,why1 the trees in the pasture have a chance to spread out1 said ,donald4 ,there isn't so much room in here4 ,but these trees are taller1 said ,frank1 and they are straighter1 too4 ,can you tell the direction of the winds that blow the strongest and longest by the shape of the trees8 asked ,uncle ,robert4 ,i never thought of that1 said ,frank4 ,the wind doesn't blow in the woods1 said ,donald4 ,when we get out into the pasture we'll notice the trees there1 said ,mr4 ,leonard4 ,isn't this a tiny tree8 said ,susie4 ,i wonder what it is4 ,that's an oak1 said ,frank4 ,the leaves tell that4 ,oaks grow from acorns1 said ,donald4 ,i'm going to dig this up and see if it grows like the seeds in the garden4 ,what a long root it has6 said ,susie as ,donald dug about it4 ,don't take it out1 ,don4 ,put the dirt back and let it grow to be a tree4 ,illustration3 ,oak sprout4 ,how long will it be before it gets as big as these trees1 uncle8 asked ,frank4 ,a great many years4 ,perhaps your father can tell about how old some of these trees are4 ,i have cut some1 said ,mr4 ,leonard1 that were about a hundred years old4 ,why1 father1 exclaimed ,susie1 how could you tell8 ,do you know how the end of a log looks when it is sawed off straight8 ,i do1 said ,frank4 ,there are light and dark rings in it4 ,well1 was the reply1 one of these rings grows every year4 ,so if you count the rings you can tell how old the tree is1 said ,donald4 ,isn't that great6 ,illustration3 ,end of a log4 ,what time of the year do the trees grow the most8 asked ,uncle ,robert4 ,in the spring ,i should think1 said ,frank4 ,that's when the sap begins to run4 ,what is sap8 ,it must be the water that the trees take up from the ground1 said ,frank4 ,we've tapped some maple trees for sap1 said ,donald4 ,and we could see it run right out of the tree1 said ,susie4 ,i've told the children how we used to make maple sugar in ,new ,england1 said ,mrs4 ,leonard4 ,do you remember1 ,robert1 what a quantity of sap it took to make just a little sugar8 ,yes1 and ,i also remember how long ,i thought it took to boil it down into the wax ,i was so fond of4 ,about thirty gallons of sap can be taken from one tree each year1 said ,mr4 ,leonard4 ,but ,i should think that would hurt the tree1 said ,frank4 ,no1 replied ,uncle ,robert1 for the hole they make is only about an inch across4 ,if they were to cut all around the tree1 you see1 it would stop the running of the sap and kill the tree4 ,that is called girdling1 said ,mr4 ,leonard4 ,they used to clear off hundreds of acres of land in that way when this country was first settled4 ,instead of cutting down the trees1 they girdled them near the ground4 ,in a very short time they died1 because they could get no food from the earth4 ,the dead trees lost their strength1 and a strong wind would blow them over4 ,then they were piled up and burned4 ,how do you know when a tree is dying8 asked ,uncle ,robert4 ,the leaves turn yellow1 said ,donald4 ,but the leaves turn yellow in the fall1 said ,frank1 and the trees do not die4 ,the leaves of my spruce don't turn yellow in the fall1 said ,donald4 ,they stay green all winter4 ,what makes the leaves green8 asked ,uncle ,robert4 ,no one answered4 ,what is the color of the potato sprouts in the cellar8 ,yellow1 said ,susie4 ,when you take up a board that has lain on the grass1 what is the color of the grass8 ,yellow1 said ,donald4 ,why8 asked ,uncle ,robert4 ,because they don't get any light1 said ,frank4 ,you know why we put our plants in the south window in winter8 said ,mrs4 ,leonard4 ,oh1 yes1 said ,susie1 because the sun shines in at that window4 ,warmth and water and air help trees and plants to grow1 said ,uncle ,robert1 but without sunlight their leaves would be yellow and their stems and branches weak4 ,the greatest forests on earth are where it is very hot and moist4 ,the sun is a wonderful artist1 and every leaf it paints makes the tree stronger4 ,but what makes the leaves turn yellow and red just before they fall off8 asked ,frank4 ,does the sun paint them then8 ,that is a question that no one has been able to answer1 replied his uncle4 ,but how can the sap flow up the tree8 said ,donald4 ,i should think it would run down4 ,it would unless there was something to draw it up1 said ,uncle ,robert4 ,i suppose the sun does that1 too1 said ,frank4 ,where does it go after it reaches the leaves8 asked ,uncle ,robert4 ,why1 back again1 said ,susie4 ,no1 it doesn't go back--not a drop1 laughed ,uncle ,robert4 ,does it dry up8 asked ,donald4 ,what do you mean by drying up8 ,it evap-o-rates1 said ,donald1 who liked to use large words4 ,does it all go into the air8 asked ,frank4 ,i want you to answer these questions yourselves1 children4 ,what do you see on the corn leaves in the early morning8 ,drops of water2 but that is dew1 isn't it8 asked ,frank4 ,uncle ,robert had a way of stopping or changing the subject when he had asked certain questions4 ,he knew that the children would think of them again and try to answer them4 ,let's sit down on this log1 said ,susie4 ,i want to fix my flowers4 ,as they sat there squirrels ran up the trunks of the trees and laughed at them from the branches4 ,that is a good shot1 said ,frank1 pointing to a large fox squirrel4 ,but he knows we won't kill him1 and that's the reason he shows himself4 ,is it right to shoot the pretty squirrels1 ,uncle ,robert8 asked ,susie4 ,i thought so when ,i was a boy4 ,i shot a great many of them then4 ,it was fun for me1 and ,i felt very proud when ,i brought home half a dozen grays4 ,once ,i went home from the city for a summer's rest4 ,i took my gun for a stroll in the oak woods where ,i had shot so many squirrels4 ,i put my gun against a tree and lay down upon the leaves4 ,soon ,i was fast asleep4 ,i dreamed of a group of merry1 laughing children running1 scampering1 playing4 ,illustration3 ,the squirrel ,then my dream became real--not children1 but the gray coats1 five or six of them1 close to me1 were running up the trees1 jumping from limb to limb1 scampering over the ground1 chasing each other1 laughing as squirrels laugh1 and screaming as squirrels scream4 ,i watched the happy playmates1 brim full of fun4 ,i have never shot a squirrel since4 ,,chapter ,,ix4 ,,the ,,birds ,,and ,,the ,,flowers ,the little family party strolled on through the beautiful woods1 following the windings of the creek that was now a tiny stream4 ,illustration3 ,the creek in the woods ,here and there were little holes hollowed out by the spring floods4 ,miniature falls gurgled over dead leaves4 ,graceful ferns fringed the creek's banks4 ,mosses covered the bowlders4 ,through the foliage danced the rays of the bright sun1 casting wavering shadows over the leaf-covered ground4 ,here is the pond6 cried ,susie4 ,but the pond that formed the reservoir of the creek was now nearly drained1 and in place of water there was a swamp filled with reeds1 rushes1 and grasses4 ,a small clear pool remained in the center4 ,illustration3 ,blackbirds4 ,on the tall reeds swaying to and fro piped a family of blackbirds1 busily chattering to each other4 ,overhead in the cloudless sky floated a huge hawk4 ,in the spring this ground is all covered with water2 it makes quite a large lake1 said ,mr4 ,leonard4 ,you thought of draining off the water and turning the pond into a cornfield1 didn't you1 father8 asked ,mrs4 ,leonard4 ,yes1 said ,mr4 ,leonard2 by digging a ditch or making the channel deeper at the outlet1 this would become dry land the year around4 ,the soil is deep and rich-better even than the bottom land4 ,that would spoil the creek1 wouldn't it1 father8 asked ,frank4 ,yes1 it would run in the spring only1 said ,mr4 ,leonard4 ,where would the cattle drink in the summer8 asked ,donald4 ,that's the difficulty4 ,the swamp holds enough to keep the cattle in water all summer4 ,would the corn more than pay for the loss of the water8 asked ,frank4 ,yes1 ,i think so1 answered his father4 ,but it would spoil my beautiful creek1 said ,susie4 ,don't do that4 ,if this swamp were in ,new ,england1 said ,uncle ,robert1 the farmers would dig out this rich mud for their poor land4 ,oh1 cried ,susie1 the blue flags are almost in bloom6 ,there is one all blossomed out1 said ,donald4 ,i'll get it4 ,the boys took an old log and threw it across the wet place1 and ,donald1 balancing himself carefully1 went out and picked the blooming flag with its buds4 ,thank you1 ,donald1 said ,susie1 as he handed her the pretty flowers4 ,i'll put the buds in water and they will open4 ,illustration3 ,blue ,flag4 ,do you know the names of all the flowers in your bouquet8 asked ,uncle ,robert4 ,every one of them1 said ,susie4 ,this is phlox4 ,there is ever so much of it in the woods now4 ,and this is a trillium4 ,isn't it big and white8 ,here is another1 only it is red4 ,we used to call the red ones 'wake-robin' in ,new ,england1 said ,uncle ,robert4 ,i thought they came earlier than the white ones4 ,they do1 said ,susie4 ,they've been here a long time4 ,the violets are just as pretty as when ,i came1 aren't they8 said ,uncle ,robert4 ,do they stay all summer8 ,not quite1 replied ,susie4 ,but they stay a long time in the woods4 ,what is this8 asked ,uncle ,robert1 pointing to a pale-pink flower on a hairy stem1 surrounded by rough green leaves4 ,that's a wild geranium1 said ,susie2 but do you think it looks-much like a geranium8 ,i don't4 ,no1 but here is a seed pod1 said ,uncle ,robert4 ,it looks like the seed of the geranium that grows in the garden4 ,perhaps that is what gave it the name4 ,illustration3 ,wild geranium4 ,i have a flower that you haven't1 ,susie1 said ,mrs4 ,leonard1 holding it up for them to see4 ,oh1 cried ,susie1 a yellow lady's slipper6 ,i didn't know they were out yet4 ,where did you find it8 ,i picked it on the bank near the creek while you were talking about the trees1 replied her mother4 ,i wish ,i could find a pink one1 said ,susie1 looking around4 ,isn't it too early for them8 asked ,uncle ,robert4 ,they come about the same time as the yellow ones1 said ,donald1 but we don't find very many of them4 ,i like the ,indian name for that flower1 said ,mr4 ,leonard4 ,do you mean moccasin flower1 father8 asked ,frank4 ,i like that too4 ,illustration3 ,yellow lady's slipper4 ,why don't we call it that8 asked ,donald4 ,lady's slipper is easier to remember1 said ,susie4 ,here are some bluebells1 ,susie1 said ,frank1 holding up a handful of the dainty1 graceful blossoms4 ,give some to mother1 and you may have the rest4 ,how many blue flowers we have6 said ,susie4 ,there aren't any red ones excepting the red trillium1 and that's so dark it isn't really red4 ,it's more purple than red1 said ,donald4 ,this isn't the time of the year for red flowers1 said ,mrs4 ,leonard4 ,they come later in the summer and in the fall4 ,i wonder why there are no red ones in the spring1 said ,susie4 ,i saw painted cups along the edge of the timothy meadow yesterday1 said ,donald4 ,illustration3 ,moccasin flower4 ,oh1 did you1 ,don8 ,were they truly red1 or just yellow8 ,no1 they were in bloom4 ,they were red4 ,let's go home that way1 said ,susie1 and get some4 ,i wish all the people in ,new ,york could know how restful these woods are1 said ,uncle ,robert1 breathing a long breath of the sweet1 pure air4 ,it always seems to me more quiet in the woods on ,sunday than on any other day1 said ,mrs4 ,leonard4 ,do the birds know when it is ,sunday8 asked ,susie4 ,if they do1 said ,uncle ,robert1 those blue jays must have forgotten4 ,just hear how they scream6 said ,frank4 ,they must be up to their usual trick1 said ,mr4 ,leonard1 of tormenting some other bird4 ,listen6 said ,donald4 ,it's a sparrow hawk they're after4 ,that's the sparrow hawk's cry1 but it's a blue jay that made it4 ,they always mimic them when they chase them4 ,i've watched them lots of times4 ,illustration3 ,blue jay4 ,i wish we could see them now6 said ,frank4 ,the hawk will turn on them soon4 ,then they'll change their tune4 ,they are having a good time shouting and screaming to each other1 said ,susie4 ,what a horrid noise they make6 ,they scare away the other birds1 said ,donald4 ,how many birds do you know8 asked ,uncle ,robert4 ,illustration3 ,robin4 ,i know all the birds that come around the house and the barn1 said ,donald4 ,there are the robins1 sparrows1 pewees1 wrens1 swallows1 and martins4 ,then there are the birds in the fields--the larks and the crows4 ,the names of some of the little birds in the woods ,i do not know4 ,you have left out the woodpeckers1 said ,frank1 and the thrushes and catbirds4 ,and the cherry birds1 that look like canaries1 said ,susie4 ,get up early in the morning1 just as the sun is rising1 and you will hear a chorus1 said ,mrs4 ,leonard4 ,it is a regular morning praise meeting4 ,illustration3 ,woodpecker4 ,the oriole1 or golden robin1 is the handsomest bird of all1 said ,donald4 ,a great many birds come in the spring which stay only a few days1 said ,frank4 ,where do they come from1 and where do they go8 asked ,uncle ,robert4 ,they come from the south1 ,i suppose1 where it is warmer4 ,i wonder how they know when it is time to start1 said ,frank4 ,and which way to go1 added ,donald4 ,and how they decide where to stop and build their nests1 said ,mrs4 ,leonard4 ,illustration3 ,oriole4 ,very interesting questions1 but no one has answered them yet1 said ,uncle ,robert4 ,migrating birds are all found in the south in winter1 and we see them in the spring4 ,what do you mean by mi-grat-ing birds8 asked ,susie4 ,birds that fly from one part of the country to another1 said ,uncle ,robert4 ,the bluebird is the first to come1 said ,donald4 ,a patch of blue sky1 said ,uncle ,robert4 ,you forget the geese that screech over our heads in the early spring1 said ,frank4 ,they fly in flocks shaped like an arrow4 ,illustration3 ,bluebird4 ,the 'bobwhite' is the funniest little bird4 ,one comes right up to my garden fence4 ,it is a shame to shoot them6 said ,susie4 ,it is a shame to kill any bird unless you need it for food4 ,every time a bird is killed the farmer loses one of his best helpers4 ,the birds work for the farmer from morning to night4 ,oh1 now you are making fun1 ,uncle ,robert1 said ,susie4 ,the birds don't work at all4 ,they just fly around and have a good time4 ,the crows don't work for the farmer when they pull up his corn1 said ,frank4 ,nor the hawks when they steal his chickens1 added ,mr4 ,leonard4 ,the cherry birds steal the cherries1 and the sparrows eat the strawberries1 said ,susie4 ,you would soon find out how much the birds do if they should all fly away1 said ,uncle ,robert4 ,illustration3 ,crow4 ,the cankerworms would eat the leaves of the apple and other trees1 and insects of all kinds would destroy the crops4 ,the crow taxes the corn in payment for all the good he does4 ,the hawks eat a thousand mice to one chicken--in fact1 very few hawks eat chickens1 anyway4 ,the cherry birds and sparrows should be allowed a little toll for all the fruit they save4 ,i want you to read a charming book called ,the ,great ,world's ,farm4 ,the author calls birds ',nature's militia4' ,the morning song of the birds means ',we are going to help the farmer to-day4' ,that's true1 said ,mr4 ,leonard4 ,the farmers are just learning what a help the birds are to them4 ,we have found that they eat the grubs1 the worms1 and the bugs before they eat everything else4 ,would there be very many more worms than there are now1 asked ,susie1 if the birds should go away8 ,you don't remember1 do you1 ,susie1 said her mother1 how many caterpillars there were in the village the year they tried to drive the sparrows away8 ,i do1 said ,donald4 ,wasn't it dreadful8 ,why1 ,uncle ,robert1 the leaves were all eaten off the trees1 and you could hardly take a step without squashing a caterpillar4 ,ugh6 said ,susie with a shudder4 ,i'm glad ,i was too little to remember it4 ,but the strange part of it was1 said ,frank1 that out here we hardly saw a caterpillar all summer4 ,and our trees were never more beautiful1 said ,mrs4 ,leonard4 ,perhaps the village sparrows came to visit you1 said ,uncle ,robert4 ,they must have1 said ,donald4 ,the woods were full of them4 ,i have read1 said ,uncle ,robert1 that some small birds eat every day as much as their own weight in worms and insects4 ,oh1 my6 said ,susie4 ,i wonder how many worms that would be4 ,the appetite of the small bird1 said ,mr4 ,leonard1 looking at ,donald with a smile1 must be something like that of a small boy4 ,they had now left the woods and were going toward the timothy meadow to get the painted cups4 ,donald was right4 ,one corner of the meadow was bright with the vivid red patches4 ,the sun was setting when they reached home4 ,as they passed the woodpile in the back yard ,donald said3 ,i wonder how old that wood is6 ,i'm going to see if ,i can count the rings4 ,show them to me1 ,donald1 said ,susie4 ,i never saw them4 ,just then the clear1 rich song of a bird rang out from the top of a tree on the edge of the woods4 ,hark6 said ,mr4 ,leonard4 ,that is the thrush4 ,they listened until the song was ended4 ,what a lovely walk we have had6 said ,susie4 ,i'm not a bit tired4 ,are you1 mother8 ,well1 a little1 said ,mrs4 ,leonard1 but we never had a more delightful afternoon4 ,thank you1 dear1 as ,frank brought an easy-chair from the house to the porch for her4 ,now ,i shall be rested in a few minutes4 ,let me put your flowers in water with mine1 mother1 said ,susie4 ,tell ,jane to bring our supper out here1 said ,mrs4 ,leonard4 ,it is too pleasant to go in the house4 ,and tell her to be quick about it1 said ,donald4 ,i'm starving6 ,as hungry as a sparrow1 said ,uncle ,robert1 smiling4 ,while they were eating1 the twilight came on4 ,listen6 whispered ,frank1 as a queer1 clucking sound was heard among the bushes4 ,then came the cry3 ,whip-poor-will6 whip-poor-will6 ,i wish ,i could see a whip-poor-will1 said ,donald4 ,they never let me get near enough to them to see how they look4 ,let's try this one1 said ,frank4 ,it's very near4 ,on tiptoe they slipped off the porch1 but the shy bird heard them and flew away4 ,soon they heard it again3 ,whip-poor-will6 whip-poor-will6 ,and another one answered from the edge of the cornfield3 ,whip-poor-will6 whip-poor-will6 ,illustration3 ,whip-poor-will4 ,,chapter ,x4 ,,the ,,thundershower4 ,it had been growing warmer all day4 ,when ,susie looked at the thermometer at noon she wrote #hb degrees in her little book4 ,as they sat around the dinner table ,uncle ,robert asked3 ,do you find it hot in the meadow to-day8 ,rather warm1 replied ,mr4 ,leonard1 but it is fine haying weather4 ,by night we shall have the hay in off that twenty acres1 and it will be the finest crop of timothy ,i have had in years4 ,the haying had begun four days before4 ,for a week ,mr4 ,leonard had visited the field of timothy daily1 and when he found the long heads of the graceful grass in full bloom he said3 ,it is ready4 ,we must begin to-morrow4 ,so the next morning the horses were hitched to the mowing machine1 and ,peter drove out to the meadow4 ,the plumy heads of the tall timothy swayed on their slender stalks as they bowed before the breeze that swept over the meadow1 making it look in the sunshine like the rippling surface of a quiet lake4 ,illustration3 ,mowing the meadow4 ,it seemed a pity to cut it down1 but ,peter thought only of the fine hay it would make1 as he drove around the meadow again and again1 each time coming nearer the center4 ,no sound broke the stillness but the click1 click of the sharp knives1 at the touch of which the tall grass quivered a moment and then fell4 ,in the afternoon ,donald rode the rake1 to which one of the horses1 strong and steady1 was hitched4 ,the horse knew his business4 ,he needed no direction from ,donald as up and down the meadow he went1 with slow and even steps4 ,donald sat on the small round seat1 his hand grasping the lever by which he raised and lowered the long curved teeth of the rake that gathered up the hay and dropped it in long rows called windrows4 ,mr4 ,leonard and ,frank followed with their pitchforks1 and piled the windrows into big round cocks4 ,the sun shone hot and clear4 ,a strong1 dry south wind was blowing1 and the air was filled with the sweet smell of the newly mown hay4 ,the second day ,mr4 ,leonard rode the machine while ,peter and ,frank opened the hay that had been cocked the day before1 so that it would be nicely dried4 ,by noon it was all cut4 ,the next day they raked it up for the last time and began to stow it away in the big haymows in the barn1 where the very smell of it would make the horses hungry4 ,susie and ,i are coming out to help this afternoon1 said ,uncle ,robert1 as1 after a short rest in the cool porch1 the haymakers1 started for the meadow again4 ,we'll take all the help we can get1 replied ,mr4 ,leonard4 ,i am afraid it is going to rain1 said ,uncle ,robert1 as he started a little later with ,susie for the hayfield4 ,the barometer has fallen since morning4 ,but1 uncle1 said ,susie1 ,i don't see any clouds4 ,illustration3 ,raking and cocking hay4 ,watch1 and you'll see them before long1 returned ,uncle ,robert4 ,what is that in the west now8 ,it looks like the beginning of a cloud1 said ,susie4 ,mr4 ,leonard1 ,peter1 and ,frank were loading the hay into a big wagon1 while ,donald raked after them4 ,there's a shower coming1 said ,uncle ,robert1 pointing toward the west4 ,all paused and looked at the bank of clouds just coming into sight along the western horizon4 ,the air was still and sultry4 ,great beads of perspiration rolled down the faces of the haymakers4 ,it's going to rain1 sure1 shouted ,mr4 ,leonard1 and we must hurry or this fine hay will be spoiled4 ,harness up the horses to the other hayrack1 ,frank and ,donald--be quick6 ,the boys did not need urging4 ,they felt the need1 and ran to the barn4 ,bring some extra pitchforks6 shouted their father after them4 ,uncle ,robert pulled off his coat1 and the spirit of his boyhood days came back4 ,susie seized a rake and began to gather the scattered hay and pile it on the cocks4 ,the fresh span of horses galloped into the field4 ,frank brought them to a stand between two long rows of haycocks4 ,how they all worked6 ,the very horses seemed to understand4 ,they started with a jump to each new cock1 and stood perfectly still as one after the other was added to their load4 ,it is coming6 shouted ,peter1 swinging his fork to spread the great bundles of hay which came flying up to him4 ,the clouds looked like mountains with snowy peaks as they rose rapidly in the southwest4 ,the mass moved under the sun and the bright silver color changed to blackness4 ,lightning flashes followed one another quickly4 ,the low rumbling of thunder stirred the still air4 ,it is coming6 cried ,donald1 as he took the reins to move to another cock4 ,g'long6 ,all was hurry and excitement4 ,mrs4 ,leonard and ,jane appeared on the scene with rakes in hand4 ,barri bounded from horse to horse as if that was some help4 ,suddenly it grew darker4 ,the leaves began to quiver4 ,a curious light crept over the fields4 ,there is the wind1 shouted ,frank4 ,the rain will be here in a minute4 ,clouds completely covered the sky4 ,black forms seemed to dart out of their heavy masses4 ,there's a drop1 cried ,susie4 ,then what a wind6 ,straw hats were whirled away1 but there was no time to run after them4 ,pile up the hay6 ,the great loads staggered4 ,drive for the barn6 shouted ,mr4 ,leonard4 ,some of it must spoil1 ,i suppose4 ,we have done our best4 ,the horses moved off on the run1 ,frank's team ahead4 ,a roll and a crash of thunder followed a zigzag flash4 ,the hay was under cover1 and the rain poured down4 ,illustration3 ,the coming storm4 ,they reached the porch just as it began to fall thick and fast4 ,a moment more and it came down in floods1 while at the same time the darkness passed away4 ,how cool it is growing6 said ,mrs4 ,leonard4 ,it is twelve degrees cooler than it was at noon1 said ,donald1 looking at the thermometer4 ,see1 the wind has changed4 ,it is from the northeast now4 ,frank went into the dining-room1 and when he came back he said1 ,the barometer has risen two-tenths of an inch since we looked at it last4 ,it seemed to rain harder than ever4 ,the water was driven in sheets before the strong northeast wind4 ,a stream began to run down the garden path4 ,a vivid flash of lightning was followed quickly by a loud crash of thunder4 ,that struck somewhere near1 said ,frank4 ,i believe it was over in the wood1 said ,mrs4 ,leonard4 ,see1 said ,uncle ,robert in a few moments1 pointing to a line of light in the western sky1 it is clearing already4 ,the shower will soon be over4 ,the light in the west grew rapidly4 ,the lightning became less frequent4 ,the thunder rolled farther and farther away4 ,the rain fell less and less heavily4 ,the weather vane that had pointed to the northeast began to waver1 and then turned toward the southwest again4 ,it rained steadily but more gently as the clouds rolled away eastward4 ,and then the sun1 lower now by two hours than when it was first hidden by the cloud1 shone out clear and bright4 ,instantly everything glistened as with millions of diamonds4 ,even the air seemed to be filled with them1 as though each raindrop was turned into a jewel as it fell4 ,uncle ,robert went to the front of the house and looked toward the dark cloud that was now piled up in the eastern sky4 ,come and see the rainbow6 he called4 ,as they looked at the bright and perfect arch that lay against the dark mass of clouds1 ,susie asked1 ,what makes rainbows1 uncle8 ,it is the sun shining on the rain1 replied ,uncle ,robert ,this beautiful sunlight is made up of many1 many rays4 ,these rays fly from the sun as straight as arrows from a bow1 unless something comes in their way to stop them4 ,it seems as though such sharp little arrows of light would go right through raindrops4 ,but they don't4 ,they glance off the little round balls of water and bound up again like rubber balls4 ,now you know if you throw a ball straight down at your feet it bounds back into your hands4 ,if you throw it from you1 when it strikes the ground it bounds farther away4 ,it is just so with these little arrows of light that we call rays4 ,if the sun is high1 as it is at noon1 the rays are thrown back to it again4 ,that is why we never have rainbows at noon4 ,but when the sun is low1 as it is now1 instead of going back to the place they came from1 they bound up against that cloud1 and so make the wonderful rainbow4 ,but1 uncle1 asked ,donald1 why do we see so many colors in the rainbow8 ,they are not in the sunlight4 ,oh1 yes1 they are1 was the answer4 ,these rays of light are of the same colors that we see in the rainbow4 ,it takes all of them mixed together to make the clear white light which we call sunlight1 and without which nothing could live or grow4 ,as the raindrops throw them up against that cloud1 they are separated again1 because some colors are more easily bent than others4 ,the red1 you see1 is the highest and the violet the lowest in the bow4 ,the raindrops make a prism4 ,you have seen a prism4 ,but through the prism the colors are turned the other way2 the red is lowest and the violet highest4 ,how fast the rainbow is fading away6 said ,susie4 ,i wish it would stay4 ,the rain is over1 announced ,donald1 leaving them and walking out toward the garden4 ,the sky is quite clear4 ,it is getting warm again1 said ,frank1 looking at the thermometer1 but it does not feel hot as it did before the rain4 ,the barometer is just where it was this morning1 said ,susie1 coming from the dining-room4 ,it is drying off very fast1 said ,uncle ,robert4 ,let us walk out and see how the garden stood its drenching4 ,put on your rubbers1 ,susie1 called ,mrs4 ,leonard from the house4 ,as they crossed the yard they passed a pan in the bottom of which the water stood an inch or more deep4 ,that shows how much rain fell1 said ,uncle ,robert1 pointing to the pan4 ,do you mean if it had stayed on the ground where it fell it would have been that deep all over8 asked ,susie4 ,would that have been very much8 ,i think it would1 was the smiling reply4 ,you might try to find out how much fell on the garden alone if it was an inch deep all over4 ,susie shook her head4 ,i don't know how1 she said4 ,uncle1 said ,frank1 in the weather reports they always tell how much rain falls1 even if it is only a small part of an inch4 ,how can they tell when it is so little8 ,they have what is called a rain gauge1 by which a very small amount of rainfall can be measured4 ,by the way1 we might have a rain-gauge of our own4 ,it would be easy to make one with the help of a tinsmith4 ,is there a tinsmith in the village8 ,yes1 answered ,frank1 but ,i don't believe he has much to do4 ,so much the better for us1 laughed ,uncle ,robert4 ,susie1 while these other people are busy tomorrow1 shall we drive to the village and see if we can get the tinsmith to help us make a rain-gauge8 ,i have a little book somewhere that tells just how it should be done4 ,susie was delighted at the thought of such a day with ,uncle ,robert1 and the boys were so interested in the prospect of having a rain-gauge of their own that they could hardly wait for to-morrow to come4 ,,chapter ,,xi4 ,,the ,,village4 ,the next morning ,frank harnessed ,nell for ,uncle ,robert and ,susie to drive into the village to see the tinsmith4 ,it was a delightful ride through the woods and the fields washed clean by the rain4 ,the birds were singing gayly4 ,the air was fresh and clear4 ,long shadows lay along the road4 ,the tinsmith was sitting by his open door1 tilted back in an old wooden chair4 ,as ,nell stopped1 he brought his chair down on its four legs and said3 ,good morning4 ,uncle ,robert lifted ,susie out of the wagon and hitched ,nell to a post4 ,the tinsmith rose to his feet1 smiling to ,susie1 who said3 ,this is my ,uncle ,robert1 ,mr4 ,mills4 ,we've come to have a rain-gauge made4 ,good morning1 said ,uncle ,robert1 turning to ,mr4 ,mills1 who looked as if he thought rain gauges were not exactly in his line4 ,can you spare us a little time this morning8 ,susie must have her rain-gauge before the next shower4 ,come right in1 said ,mr4 ,mills1 and tell me what your rain-gauge looks like4 ,i never heard of such a thing4 ,with ,uncle ,robert's careful direction he soon understood what they wanted4 ,they saw him well started in the work1 and then ,uncle ,robert said3 ,come1 ,susie1 let's go to the post office4--,how long before the rain-gauge will be finished8 he asked of ,mr4 ,mills4 ,shall we have time to get dinner8 ,i think ,i can have it ready by two o'clock1 answered ,mr4 ,mills4 ,then we'll take ,nell to the hotel1 said ,uncle ,robert4 ,they drove slowly under the big cottonwood trees which shaded the street4 ,isn't it nice that it takes such a long time to make a rain-gauge8 said ,susie4 ,here we are at the hotel now1 ,uncle ,robert4 ,it's such a little way4 ,from the hotel they strolled to the store1 the center of life and interest in the village4 ,illustration3 ,the village street4 ,one corner of the store was taken up by the post office4 ,back from that ran long lines of shelves which reached to the ceiling4 ,beneath them were bins for flour and sugar4 ,on the lower shelves were canisters of tea1 coffee1 and spices1 and glass candy jars1 which looked very inviting to ,susie4 ,some were filled with gay-striped sticks4 ,there were also jars of peppermint lozenges1 star--and heart-shaped1 with pink mottoes on their white faces4 ,on the upper shelves were rows upon rows of cans covered with gay pictures of fruits and vegetables4 ,opposite the groceries were long shelves of dry goods4 ,a glass case at one end of the counter was filled with bright-colored ribbons4 ,in the darkness at the back of the store stood the barrels of vinegar1 molasses1 and kerosene oil4 ,above them hung rows of well-cured hams and sides of bacon4 ,near the barrels stood an old rusty stove which bore the marks of long use4 ,uncle ,robert asked for the mail4 ,susie looked longingly at the glass jars upon the shelf1 trusting that ,uncle ,robert would understand her even if she didn't say anything4 ,we must have some candy1 he said4 ,tell ,mr4 ,jenkins what you would like1 ,susie1 while ,i look at my letters4 ,susie carefully picked out three sticks of peppermint1 three sticks of lemon1 and three of cinnamon4 ,if you please1 ,i'd like some of the mottoes1 too4 ,mr4 ,jenkins handed down the jar1 spread out a clean sheet of wrapping paper1 and turned out the candies4 ,susie selected a dozen hearts1 rounds1 and stars1 with different mottoes1 and then wondered if she ought to have lemon drops1 too4 ,do you think ,i have enough1 uncle8 she asked4 ,uncle ,robert knew pretty well what little girls like4 ,no1 ,susie1 he said1 you have forgotten the lemon drops1 and1 let me see1 nut candy--we must carry home enough for mother and the boys4 ,just then a little girl in a pink sunbonnet1 carrying an oil can in her hand1 came through the open door4 ,how d' do1 ,susie1 she said1 with a shy glance at ,uncle ,robert4 ,how d' do1 said ,susie4 ,have some of my candy1 ,jennie8 holding it out to her4 ,uncle ,robert bought it for me4 ,there he is1 in a loud whisper4 ,good morning1 ,jennie1 said ,uncle ,robert1 putting his letters in his pocket4 ,you haven't been out to see ,susie since ,i have been here4 ,it's ,jennie's mother who had the nasturtiums last year1 said ,susie4 ,have you any now ,jennie8 ,yes1 but they don't grow well this year1 answered ,jennie4 ,perhaps you need new seeds1 said ,uncle ,robert4 ,they are apt to do better if they are raised on different soil4 ,i have some nasturtiums this year1 ,jennie1 said ,susie4 ,they are just beginning to blossom4 ,i'll save you some seed if you want me to4 ,come out some day and see ,susie's flowers1 ,jennie1 said ,uncle ,robert kindly1 as they left the store4 ,good-by1 ,jennie1 said ,susie4 ,time for dinner1 said ,uncle ,robert4 ,i'm hungry4 ,susie's eyes danced4 ,they went into the dining-room and sat down at the long table4 ,through the window they could see the hotel garden from which the flowers on the table had been gathered4 ,what shall we do now8 asked ,uncle ,robert as1 after dinner1 they stood upon the porch1 looking up and down the street4 ,no sound was heard but the sleepy noonday song of the grasshopper and the occasional rattle of a wagon going down to the store4 ,let's go to the mill1 said ,susie4 ,the mill wasn't running when we passed there this morning1 said ,uncle ,robert4 ,suppose we wait until some time when the boys are with us4 ,then we can go all through it1 and see just how wheat is changed into flour4 ,oh1 yes1 said ,susie1 that will be the nicest4 ,we might go to the station and see the train come in1 suggested ,uncle ,robert1 looking at his watch4 ,oh1 that's fun6 ,come on1 uncle1 cried ,susie1 running down the steps4 ,see1 they are all going down now6 ,all right1 said ,uncle ,robert1 but don't hurry2 there's plenty of time4 ,as they looked down the track they could see the steel rails gleaming in the hot sunshine4 ,the two shining lines stretched away until they seemed to meet in the distance4 ,in the other direction a faint line of smoke appeared over the trees4 ,it grew more and more distinct1 until at last an engine rounded the curve and came puffing heavily up the track1 pulling a long line of cars behind it4 ,that's a freight train1 said ,uncle ,robert4 ,it stops here to let the passenger go by1 said the station master1 who stood near4 ,expecting some one to-day1 sir8 ,the train isn't due for ten minutes4 ,not to-day1 replied ,uncle ,robert4 ,do many trains stop here8 ,not many1 said the station master as he hurried away to the switch4 ,illustration3 ,a freight train4 ,the great engine1 drawing its heavy load after it1 turned into the side track4 ,when the small caboose at the end had passed the switch a man1 who was running upon the tops of the cars1 waved his arms and the long line stood still4 ,the engine breathes hard--just like ,barri after a long run1 said ,susie4 ,i wonder what is in all these cars1 uncle4 ,here is one marked ',furniture1' from a large factory in ,grand ,rapids1 said ,uncle ,robert1 reading the white card that was tacked on the side4 ,it is going to a town in ,nebraska4 ,what funny cars these open ones are6 said ,susie2 the ones with the shelves in4 ,what are they for8 ,they're empty1 too4 ,i shouldn't think they'd want to drag empty cars about4 ,these are the cars poultry is shipped in1 explained ,uncle ,robert4 ,perhaps they have been to ,chicago with chickens for the market1 and are on the way back to the place they came from for more4 ,how many of these big yellow cars there are6 said ,susie4 ,they all have re-frig-re-frig-- ,refrigerator1 prompted ,uncle ,robert4 ,oh1 ,i know what a refrigerator is1 said ,susie4 ,it's an ice box4 ,are these cars ice boxes1 uncle8 ,yes2 the great packing houses at the stock yards in ,chicago ship beef all over the country in them4 ,the fruit from ,california comes in refrigerator cars1 too4 ,there's the train6 cried ,susie1 and here comes ,mr4 ,jenkins with the mail4 ,the train came rushing on4 ,susie thought it was not going to stop4 ,but suddenly it slowed up4 ,the conductor leaped upon the platform4 ,the train stood still4 ,heads were thrust out of the windows4 ,a few passengers alighted4 ,brakemen ran along the platform4 ,all aboard6 shouted the conductor1 waving his hand to the engineer1 who was leaning out of the cab window watching for the signal4 ,ding-dong1 ding-dong1 puff1 puff1 toot1 toot1 and the train was off4 ,now we'll go and see if there is any mail for us1 said ,uncle ,robert4 ,then we'll go to the tinsmith's4 ,illustration3 ,rain-gauge4 ,the rain-gauge was just finished4 ,so ,susie waited in the shop while ,uncle ,robert went to the stable for ,nell1 who pricked up her ears when she saw him4 ,she was beginning to think she had been forgotten4 ,it was late in the afternoon when they reached home4 ,mrs4 ,leonard and the boys were looking for them when they drove in at the gate4 ,it took some time to choose just the right place for the rain-gauge1 but at last they decided upon a little rise of ground that lay between the house and the orchard4 ,there was first the funnel-shaped receiver1 one and one-half inches deep and eight inches in diameter4 ,below this was a tube two and five-tenths inches in diameter and twenty inches long4 ,at the top of this tube1 close to the receiver1 there was a small hole4 ,what is that hole for8 asked ,donald4 ,so if it rains more than enough to fill this tube1 explained ,susie1 who knew all about it1 it can run out of the hole4 ,then it will be lost1 said ,donald4 ,no1 replied ,uncle ,robert1 it is to be set inside of this cylinder1 which is twenty-three and one-half inches long1 but only six inches in diameter1 and so is smaller than the top of the receiver4 ,the water that runs from that hole falls into this4 ,by measuring it in the small tube1 and adding it to what the tube held before1 we can know how much there is in all4 ,one inch in the tube would be one-tenth of an inch in the receiver4 ,then twenty inches1 or the tube full1 would be two inches in the receiver1 said ,frank4 ,yes1 said his uncle2 but how shall we make this stand up8 ,we might pile stones around it1 suggested ,donald4 ,that will be a good way1 said ,uncle ,robert4 ,there were some stones in a pile near the orchard fence4 ,frank and ,donald picked them up and placed them about the rain-gauge until it stood firm4 ,well1 these stones are of some use after all1 said ,frank4 ,i'm glad of it1 said ,donald4 ,it seemed as though we should never get them all picked up4 ,i believe stones grow4 ,these stones tell a wonderful story1 said ,uncle ,robert1 smiling4 ,oh1 uncle1 when are you going to tell it to us8 ,to-night8 asked ,susie4 ,not to-night1 my dear4 ,you have had stories enough for one day1 and ,uncle ,robert took her by the hand and started for the house4 ,we have a regular weather bureau of our own now1 said ,donald4 ,i hope it will rain all day long to-morrow4 ,,chapter ,,xii4 ,a ,,day ,,on ,,the ,,river4 ,father1 can't we have a picnic on the river8 asked ,susie4 ,please1 do let us have a picnic1 said ,donald4 ,i think you may1 said ,mr4 ,leonard4 ,you might have it to-morrow4 ,i won't need the boys4 ,hurrah6 cried ,donald1 and ,susie skipped and danced for joy4 ,we'll have to have a nice lunch1 said ,frank4 ,what shall it be8 asked ,mrs4 ,leonard4 ,oh1 we can take some ham sandwiches-- ,and some cake and jelly1 put in ,susie4 ,and some cold chicken and boiled eggs1 added ,donald4 ,oh1 cried ,susie1 let us take our eggs along all fresh and boil them6 ,we can take a little pail and-- ,i'll tell you what we'll do1 interrupted ,frank4 ,we'll take some salt pork1 and catch some fish1 and have a fry4 ,frank looked at the barometer and said it was going to be a nice day4 ,the sun was setting clear and bright4 ,the children went to bed happy and dreamed of the fun to-morrow4 ,in the morning ,susie rushed out to see if it was good weather4 ,the sun was shining brightly1 and she turned and looked at her long shadow that reached clear over the barn4 ,the direction of the shadow was southwest4 ,donald took a tin can and went out into one corner of the garden1 where the soil was dark1 rich1 and damp1 and with a shovel dug up great mud worms1 and almost filled his can4 ,frank got out two cane poles1 rigged the lines and hooks1 and put on the sinkers4 ,i want to catch a fish1 said ,susie4 ,all right1 said ,frank2 we'll cut a pole for you when we get on the island4 ,we shall not fish till we get there4 ,uncle ,robert watched the enthusiasm of the children with a pleasant smile4 ,mrs4 ,leonard and ,susie put up the lunch4 ,put in a paper of salt for the fish1 please1 called ,frank4 ,don't believe you will catch many fish1 said ,mr4 ,leonard4 ,you know the last time you went you didn't catch any4 ,it is not a good day for fish1 said ,uncle ,robert2 it is too bright4 ,we'll get some sunfish1 anyway1 said ,donald1 and perhaps we shall catch a perch or two and a catfish4 ,at last all was ready ,frank took the oars from the beams of the shed1 ,uncle ,robert carried the big basket1 ,donald followed with the fish poles and the can of worms1 while ,susie brought up the rear with a small tin bucket4 ,away they went1 down the slope and over the bottom land to the mouth of the creek1 where the boat was moored4 ,soon they glided out from the shore under ,frank's steady stroke4 ,we will go up on this side1 where it is easier to row1 he said4 ,the current is on the other side next to the bank4 ,why do you suppose the current is over there8 asked ,uncle ,robert4 ,i don't know1 said ,frank4 ,last spring we had a big flood1 and the current was so strong that it took away a lot of earth from that bank4 ,the earth fell down into the river and was carried away4 ,mr4 ,davis lost a good deal of land4 ,tell me about the flood1 ,frank1 said ,uncle ,robert4 ,last ,march the ice broke up in the river and went tearing downstream in great blocks1 began ,frank4 ,just below the dam1 between the island and that shore1 pointing to the woods1 it piled up until there was a big ice jam4 ,you could cross over to the island on foot4 ,then the water began to rise until it was nearly even with the top of the dam4 ,at first it went round close to the ridge4 ,you see the land is lower there4 ,the part of our cornfield next to the river was an island4 ,then the water rose higher1 and spread all over the bottom land4 ,it made the mouth of the creek close to the slope1 and the water came up around the trunks of the trees4 ,on the other side1 where the current is1 it didn't get over the bank1 but it tore away lots of earth4 ,three big trees fell into the water and were carried down the river4 ,ever so many trees came down4 ,peter and ,i caught a lot and piled them up for firewood4 ,don't you remember1 ,frank1 said ,susie1 two or three sheds came down1 too8 ,the miller thought it would carry away the mill1 said ,donald4 ,the water looks pretty clear now4 ,how did it look then8 asked ,uncle ,robert4 ,at first it was clear1 said ,frank4 ,then it got just like coffee4 ,that was the dirt in the water1 said ,donald4 ,when the water went down1 continued ,frank1 the bottom land was all covered with the stuff the river left4 ,father says the dirt it brought makes the land better4 ,what do you suppose made the freshet8 asked ,uncle ,robert4 ,oh1 they said it was the snow melting1 away up the river1 answered ,donald4 ,the snow was gone here1 but we had lots of rain4 ,where is the deepest part of the river8 asked ,uncle ,robert4 ,it is quite deep on the other side1 said ,frank1 but it is shallow over here4 ,farther down it is deeper in the middle4 ,where is the current down there8 asked ,uncle ,robert4 ,in the middle of the river1 said ,frank4 ,when we go in swimming we can wade out here a long ways before we go over our heads1 said ,donald4 ,i wish ,i could swim1 said ,susie4 ,you should learn1 said ,uncle ,robert4 ,the boys could easily teach you4 ,they rowed steadily up the river4 ,at last they reached the island and landed4 ,it was long and narrow1 covered with trees and green grass4 ,here and there low bushes grew down to the water's edge1 while at the upper end there were many boulders1 stones1 pebbles1 and clean white sand4 ,illustration3 ,a string of fish4 ,they brought up the basket and put it in a cool place under a tree4 ,now for the fishing6 said ,frank4 ,up the river they could see the dam1 and on the left of the dam the flour mill4 ,there is a nice big pond up above the dam1 said ,susie4 ,we ought to go up there some day4 ,i think it is better fishing there1 said ,frank1 but we would have to drag the boat around the dam4 ,uncle ,robert stretched himself under the shade of an elm tree4 ,susie rolled up her sack and put it under his head4 ,the boys went off to try their luck at fishing4 ,they cut a pole for ,susie1 but she soon tired of sitting still1 and came back to pick up sticks for the fire so that everything would be ready to fry the fish4 ,when the boys came back they brought three little sunfish1 two perch1 and one funny-looking fish with horns1 which ,frank said was a catfish4 ,frank and ,uncle ,robert dressed the fish1 while ,donald rowed across the river to a place where he knew there was a spring1 and soon returned with a pail of clear1 sparkling water4 ,susie spread the cloth in a nice shady place1 and unpacked the basket4 ,the eggs were boiled in the tin bucket over the fire4 ,frank fried the fish1 and at last dinner was ready4 ,oh1 isn't this fun6 said ,susie4 ,grand6 said ,frank4 ,i'd like to be an ,indian and live in the woods all the time1 said ,donald4 ,we could make a fort1 said ,frank1 on that bank of the island and mount cannon1 and not allow any ships to come up the river4 ,oho6 laughed ,donald4 ,ships don't come up this river4 ,the water isn't deep enough4 ,that doesn't matter1 said ,susie2 we could play they do4 ,after the luncheon was over and the basket packed again they sat about under the trees4 ,what a good view of the dam there is from here6 said ,uncle ,robert4 ,i know why they built the dam there1 said ,frank4 ,just above the dam the water was quite swift4 ,what makes the water swift8 asked ,donald4 ,because the bed of the river slopes more there than down here1 said ,uncle ,robert2 and in places on rivers where there are rapids they build dams in order to use the water for the mills4 ,oh1 yes1 ,i know how they use the water1 said ,donald4 ,they have a sluice1 and they lift the gate1 and the water comes through1 and that turns the mill wheels4 ,in some rivers there are ponds larger than that pond up there1 where there are no dams1 said ,uncle ,robert4 ,yes1 said ,frank1 there is a little lake down the river4 ,we will go there some day4 ,it is good fishing4 ,how much better our corn looks than the corn on that hill over there6 ,i tell you1 it takes bottom land like ours to raise good corn4 ,what makes the corn such a beautiful green8 asked ,susie4 ,that is quite a question1 said ,uncle ,robert4 ,we will try and find out some day4 ,but ,i want to know what makes the bottom land richer than the land up on the prairie8 ,well1 said ,frank slowly1 ,i suppose that the dirt brought down by the river and spread out over it makes it richer4 ,where does that dirt come from8 ,way up the river4 ,if ,i should call the bottom land a flood-plain1 said ,uncle ,robert1 would you know why8 ,oh1 ,i know1 said ,donald4 ,because the water covers it when there is a flood4 ,now what made that flood-plain8 ,wasn't it always there8 ,no1 said ,uncle ,robert4 ,the river made it4 ,how could the river make the flood-plain8 asked ,susie4 ,why1 you told me a moment ago that the river brought down great quantities of dirt and left it all along the shores1 said ,uncle ,robert4 ,but it wouldn't bring down enough to make all that field1 would it8 asked ,donald4 ,the river is a great worker1 said ,uncle ,robert4 ,it is at work now1 and has been working for many1 many long years4 ,it has not only made this flood-plain1 but many others4 ,sometimes the river carries this dirt clear out into the sea1 and sometimes it piles it up at its mouth so that a delta is formed4 ,oh1 yes1 said ,donald1 we studied about that in geography when we had school1 but ,i didn't know a delta was made that way4 ,are there any deltas in this part of the river8 asked ,susie4 ,there may be1 replied ,uncle ,robert1 wherever one stream flows into another4 ,illustration3 ,the mill and dam4 ,is there one at the mouth of our creek8 asked ,frank4 ,we will look when we go back1 replied ,uncle ,robert4 ,shall we take a walk now8 ,when they reached the upper end of the island they sat down on some large boulders that formed part of the tiny beach4 ,just above them was the flood of water pouring over the dam4 ,the bright sunshine made the foam look white and glistening1 lighted here and there with colors of the rainbow4 ,the water rumbled and roared as it rushed out of the mill pond4 ,to the left were the flour mill and the village4 ,they could hear the mill wheel turning4 ,they could see a little white church half hidden among the trees4 ,a kingfisher swept by them with a voice like a watchman's rattle4 ,he knows how to catch fish better than we do1 said ,donald4 ,susie picked up some pebbles and put them in her apron4 ,she tried to get a number of colors4 ,some were nearly red1 some were blue1 and some were white4 ,can you find one that is exactly round8 asked ,uncle ,robert4 ,here's a white one that's almost round1 and ,susie held up a quartz pebble4 ,where do you suppose this little white pebble came from8 asked ,uncle ,robert4 ,did it come from away up the river--a long way8 said ,donald4 ,i think so4 ,one day this pebble was a part of some rock or quarry4 ,how it was broken off1 how it came down1 how it was made round1 is well worth studying4 ,oh1 tell us about it1 please1 begged ,susie4 ,we'll read about it together1 said ,uncle ,robert1 in the ,big ,book4 ,what book8 asked ,donald4 ,the book that lies all around us1 which was written by the ,creator of the world1 said ,uncle ,robert4 ,we are reading a page of it now4 ,just under the current out there1 said ,frank1 the bed of the river is covered with all kinds of stones4 ,some of them are as big as these boulders4 ,i suppose the river brought them down4 ,what do you think makes the pebbles round8 asked ,uncle ,robert4 ,maybe the river wears off the rough edges1 suggested ,frank1 thoughtfully4 ,yes1 said ,uncle ,robert1 the current of the river rolls them over and over on the river bed1 and they rub and grind against each other4 ,what becomes of the stuff that is worn off from them8 asked ,frank4 ,don't you see it--there8 said ,uncle ,robert1 pointing to the beach4 ,oh1 you mean the sand1 said ,donald1 taking up a handful and examining it4 ,is that the way the nice white sand is made8 asked ,susie4 ,that's what you meant when you said the river worked1 said ,frank4 ,did these boulders come down the river too8 ,the story of the boulders1 said ,uncle ,robert1 is different from the story of the pebbles4 ,the water helped grind the pebbles1 but it took ice to make the boulders4 ,ice6 the children all exclaimed4 ,yes1 ice4 ,a long1 long while ago this land was covered by a great river1 or sea of ice1 and that was the time these boulders were made1 said ,uncle ,robert4 ,can we read about that in the ,big ,book8 asked ,donald4 ,some of it1 said ,uncle ,robert4 ,there are many wonderful stories in this beautiful world--stories more wonderful than any fairy tale4 ,but we must go home now1 children2 it's getting late4 ,the setting sun threw long shadows of the trees over the river as they rowed home1 and the happy day was done4 ,,chapter ,,xiii4 ,a ,,rainy ,,day4 ,it was raining1 but no one was surprised4 ,they had expected it4 ,the day before had been one of those warm1 midsummer days1 beginning with a clear sky and a strong south wind4 ,by noon heavy white clouds that looked like heaps of down floated slowly overhead4 ,illustration3 ,the weather vane4 ,the weather vane1 which in the morning had pointed to the south1 turned from side to side1 as though uncertain which direction it liked best4 ,toward afternoon it seemed to settle the question in favor of the east4 ,the clouds did not rise higher and become thinner and more scattered1 as such clouds do if the weather is fair4 ,they kept their white1 billowy edges1 and rested heavily on straight bands of dull gray4 ,when the sun set1 the scroll--like edges of the clouds were tinged with gold and rose color1 but under the glittering fringe remained the solid banks of gray and misty purple4 ,the thermometer had been high all day1 for it was very warm4 ,the barometer had slowly but surely fallen4 ,then1 too1 the ,weather ,report1 just received1 told of a storm that had started in the southwestern part of the country and was moving northeast4 ,uncle ,robert had said1 at the rate it was traveling1 it might reach them some time the next day4 ,and now it was raining in a quiet1 steady way4 ,the clouds had lost their billowy whiteness4 ,they were one dull1 heavy1 unbroken mass of gray4 ,the wind blew steadily from the southeast4 ,a rainy day was before them4 ,the very thing we need1 said ,mr4 ,leonard4 ,the corn is just ready for it1 and the pastures are beginning to look pretty dry4 ,let's go fishing1 ,don1 said ,frank4 ,i'll go and dig some worms while you get the lines ready4 ,say we do1 said ,donald1 starting off at once4 ,do you want some company1 boys8 asked ,uncle ,robert1 smiling4 ,you bet-ter believe6 said ,donald1 catching himself just in time4 ,hurrah for the rainy day6 cried ,frank as he pulled on his rubber boots and coat and went out to dig the worms4 ,shall we take the boat8 asked ,uncle ,robert4 ,oh1 yes1 said ,donald4 ,i'll get the oars4 ,we'll have fish for dinner to-day1 mother1 said ,frank4 ,be sure you come back in time1 then1 said ,mrs4 ,leonard1 smiling4 ,i wish ,i was a boy and could go fishing in the rain1 said ,susie as she watched them start off4 ,down the hill they went1 and ,susie1 watching them from the front porch1 saw them push the boat from the landing and throw out their lines as they drifted down the stream4 ,then the trees hid them from sight4 ,it was dinner time when they returned4 ,i told you we'd have fish to-day1 said ,frank triumphantly1 holding up a string of bass and perch4 ,you boys will have to clean them1 said ,mrs4 ,leonard4 ,jane is ready to cook them now4 ,come on1 ,don1 called ,frank4 ,my1 won't they be good6 ,in the afternoon it ceased to rain4 ,it became lighter and the clouds looked higher and thinner4 ,it's going to clear off1 said ,susie1 going to the window4 ,i wonder how much rain has fallen1 said ,uncle ,robert4 ,i'm going to look at the rain-gauge1 said ,frank4 ,i'll go too1 said ,donald4 ,when they came back they said there were fifteen inches of water in the measuring tube1 which1 in the receiver1 would be an inch and a half4 ,that would just fill it1 said ,donald4 ,does that mean1 asked ,susie1 that if the rain had stayed on the ground it would be an inch and a half deep all over8 ,yes1 answered ,uncle ,robert4 ,would that be very much8 she asked1 taking the rod by which the rain in the gauge was measured and finding the mark for an inch and a half4 ,we might find out how much it would be on ,susie's garden1 said ,uncle ,robert4 ,does any one know how large the garden is8 ,no one knew4 ,let's get father's tapeline and measure it1 said ,frank4 ,oh1 do1 said ,susie1 always interested in anything about her garden4 ,when they came in ,donald said3 ,it is muddy1 but it's beginning to dry off in some places already4 ,how big is the garden8 asked ,susie4 ,it is forty feet one way1 said ,frank1 and twenty-five feet the other4 ,take your paper and pencil1 ,frank1 said ,uncle ,robert1 and draw a plan of it4 ,you might make one inch for every ten feet1 and see how that will come out4 ,frank took the paper1 pencil1 and ruler1 and soon he said3 ,it makes it four inches long and two inches and a half wide4 ,but remember1 said ,uncle ,robert1 that means forty feet long and twenty-five feet wide4 ,i'll write it down1 said ,frank2 then we'll remember4 ,so he wrote #dj on the long side and #be on the short one4 ,but we must find out how many square feet there are on the whole surface1 said ,uncle ,robert4 ,well1 said ,frank1 there are forty this way4 ,so we might think of it as a row across the garden of forty square feet1 might we not8 suggested ,uncle ,robert4 ,yes1 said ,frank2 and if we do that there will be twenty-five rows just like it1 won't there8 ,exactly1 said ,uncle ,robert4 ,how many does that make in all8 ,twenty-five forties1 said ,frank1 pencil in hand4 ,why1 that's just one thousand4 ,that sounds pretty big1 said ,susie4 ,especially when you think of the weeds1 said ,uncle ,robert1 smiling1 ,how many square inches would that be1 ,frank8 ,well1 said ,frank1 a foot is twelve inches long1 and if it is square it is twelve inches wide1 too4 ,then1 said ,uncle ,robert1 if you call them rows of twelve square inches1 how many rows would there be8 ,why1 twelve1 said ,donald4 ,and so it would be-- ,one hundred forty-four1 said ,frank4 ,then1 said ,uncle ,robert1 if there are one hundred forty-four square inches in one foot1 how many in one thousand feet8 ,one hundred forty-four thousand1 said ,frank1 after a moment's thought4 ,but the rain-gauge says that an inch and a half of rain has fallen1 said ,uncle ,robert1 and when an inch is as deep as it is long and broad1 it is called a cubic inch4 ,how much would one and one-half cubic inches be8 ,if this is one inch1 said ,frank1 looking at the paper1 half an inch deep would be half of this1 and that1 added to this1 would be an inch and a half4 ,isn't that right8 ,he went to work again1 and after a few minutes' silence he said3 ,it makes two hundred and sixteen thousand inches in all4 ,what kind of inches did we call them1 ,donald8 ,cubic inches1 said ,donald4 ,if you were to bring a pail of water from the spring1 said ,uncle ,robert1 would you say you had so many inches of water8 ,no1 said ,frank1 it would be quarts1 or gallons1 or something like that4 ,do you know how much a quart or gallon is1 ,susie8 asked ,uncle ,robert4 ,mother has a quart cup in the pantry1 said ,susie1 that she measures the milk in sometimes1 but ,i don't know how much a gallon is4 ,my new milk pail1 said ,mrs4 ,leonard1 who sat beside the window sewing1 holds just two gallons4 ,let's see how many quarts it takes to fill it1 said ,susie4 ,so they went into the kitchen1 and ,susie dipped the water with the quart cup into the tin pail4 ,eight1 she said1 when the pail would hold no more4 ,if the pail holds two gallons1 ,susie4 said ,uncle ,robert1 how many quarts are there in one gallon8 ,four4 said ,susie1 counting on her fingers4 ,illustration3 ,two gallons4 ,one quart4 ,well1 said ,uncle ,robert as they went back into the dining-room1 now we have found how many quarts there are in a gallon2 how shall we find how many gallons two hundred and sixteen thousand cubic inches will make8 ,if ,i knew how many cubic inches there are in one gallon1 said ,frank1 ,i could do it4 ,how shall we find out8 asked ,uncle ,robert4 ,we might measure a gallon1 said ,donald1 and then if we could empty it into a flat pan couldn't we measure that8 ,we can try1 said ,uncle ,robert1 if your mother has the pan4 ,you may use one of those tins ,i bake biscuit in1 said ,mrs4 ,leonard4 ,i'll get it1 said ,susie4 ,they measured it and found it was eleven inches long1 seven inches wide1 and two inches deep4 ,the gallon of water filled it one and one half time4 ,if it had been three inches deep1 said ,frank1 the water would have just filled it4 ,well1 said ,uncle ,robert1 can you find out how many inches there are in all8 ,it took some time and several suggestions from ,uncle ,robert1 but at last they found it to be two hundred thirty-one cubic inches4 ,now1 said ,uncle ,robert1 can you find how many two hundred thirty-one cubic inches there are in two hundred and sixteen thousand cubic inches8 ,i know how1 said ,frank1 figuring rapidly4 ,in a short time he found that two hundred and sixteen thousand cubic inches would make over nine hundred thirty-five gallons4 ,if you were going to water the garden with the new two-gallon pail1 said ,uncle ,robert1 how many times would you have to fill it8 ,if we took two gallons at a time1 said ,frank1 it would be--wait a minute--it would be four hundred sixty-seven and one half4 ,my1 said ,donald1 it makes my arms ache to think of it4 ,i'm going to find out how much fell on the whole farm some time1 said ,frank1 but ,i'm just tired out now4 ,where does all the rain come from8 asked ,susie4 ,i don't see how so much water can stay in the clouds4 ,it doesn't1 said ,donald1 laughing4 ,that's why it rains4 ,but where does it all go to8 asked ,uncle ,robert4 ,oh1 said ,susie1 it just goes into the ground4 ,some of it runs off into the river1 said ,donald4 ,that's what makes it rise when it rains hard4 ,i wonder if it has risen much to-day8 said ,frank4 ,we might put on our rubber boots and walk down and see1 said ,uncle ,robert4 ,it is clearing off finely4 ,it is almost supper time now1 said ,mrs4 ,leonard4 ,if you'll wait ,i'll help ,jane get it ready1 and then you can go as soon as it is over4 ,so they waited1 and by the time they started the sun was shining brightly4 ,it would be a whole hour before it would set4 ,,chapter ,,xiv4 ,,the ,,walk ,,after ,,the ,,rain4 ,the sky was clear and bright as if it had been washed by the rain4 ,the trees took on a fresher green4 ,the corn held up its tasseled heads as if conscious of the strength the clouds had given it4 ,the birds1 too1 rejoiced as they flew from tree to tree1 singing their sweetest songs4 ,how nice it is to get out after being in the house all day1 said ,susie1 skipping along by ,uncle ,robert's side4 ,see that lovely blue sky4 ,i wish ,i had a dress for my doll just that color4 ,and when we came out this morning1 said ,uncle ,robert1 ,donald thought the clouds looked as though they were solid and could never break away4 ,they're all gone now1 said ,donald4 ,i wonder where they went4 ,aren't the clouds lovely sometimes1 uncle8 ,i love to watch them when they look like great piles of snow4 ,yes1 replied ,uncle ,robert1 when ,i was a boy ,i used to lie for hours under an old apple tree and watch the clouds4 ,i fancied they had very wonderful forms1 sometimes giants and dragons and all kinds of animals4 ,illustration3 ,the clouds4 ,you can see things in them1 said ,donald4 ,i often do4 ,what are clouds made of1 uncle8 asked ,susie4 ,i wish ,i could get close to one and see what it is like4 ,when people go up in balloons1 said ,donald1 they go through clouds sometimes4 ,have you never been in a cloud8 asked ,uncle ,robert1 smiling4 ,oh1 no1 said ,susie4 ,how could ,i8 ,i've never been up in a balloon4 ,i know1 was the reply1 but have you never seen anything near the ground that looked at all like a cloud8 ,i don't remember1 said ,susie1 shaking her head4 ,we've seen fogs along the river1 said ,frank4 ,they look a little like clouds4 ,you know we see them almost every morning4 ,oh1 yes1 exclaimed ,donald4 ,don't you remember that fog we had early last spring8 ,why1 uncle1 it was so thick we couldn't see the barn from the house4 ,and1 uncle1 said ,susie1 ,i went out to the barn with father1 and in a few minutes there were little drops of water on my hair1 and all over my cloak4 ,did it last all day8 asked ,uncle ,robert4 ,oh1 no1 said ,frank1 only for a little while in the morning4 ,then it went away and the sun came out4 ,how did it go away8 asked ,uncle ,robert4 ,why1 said ,donald1 at first it began to get lighter1 and we could see things plainer4 ,and then1 chimed in ,susie1 it looked as though the fog broke up into pieces that rolled up in the sky1 and floated off just like clouds4 ,illustration3 ,the gully4 ,but what is that we see over the bottom land yonder8 ,it looks like fog1 said ,frank4 ,more like steam1 ,i think1 said ,donald4 ,if it was up there against that blue sky instead of on the ground-- said ,uncle ,robert4 ,then it would be a cloud1 said ,susie4 ,why1 ,i never thought of that4 ,they had gone through the gate in front of the house1 and were following the path that led down the slope to the spring4 ,see how the water has plowed through the ground1 said ,frank1 pointing to a gully the rain had made in the path4 ,it took a good many rains to make that gully1 said ,donald4 ,there was a little creek here for a while1 said ,frank4 ,the water has all run off now1 but it has spoiled the path4 ,will the gully get deeper every time it rains8 asked ,susie4 ,of course1 said ,donald4 ,that's what makes it4 ,why does the water run along the path8 asked ,uncle ,robert4 ,because it is lower than the ground on each side1 said ,frank4 ,how deep do you think the water will dig into the path if we do not fill it up8 asked ,uncle ,robert4 ,oh1 way1 way down4 ,i suppose1 said ,donald4 ,but if grass grew on the path1 said ,frank1 the water wouldn't wear the ground away4 ,we will have to fill it up with stones4 ,see these pebbles1 uncle1 said ,susie4 ,how did they get here8 ,they look just like those we saw on the island4 ,do you remember what ,i told you about the bowlders on the island8 ,yes1 you said the bowlders were made by ice1 answered ,susie4 ,did the ice make these pebbles8 ,perhaps so1 and perhaps the river made them and left them here4 ,what6 that river away down there8 ,how could it get up here8 ,that river away down there once flowed right over this ground1 said ,uncle ,robert4 ,this slope1 pointing just above1 was its bank1 and the ground under our feet its bed4 ,that must have been a hundred years ago1 said ,donald4 ,yes1 a great many hundred years ago4 ,you see the work this bit of a stream has done in the path8 ,many rivers begin just this way4 ,they are cutting and changing the earth all the time4 ,they had now come to the spring nearly at the foot of the slope4 ,on sultry summer days it was a cool1 inviting spot4 ,the low-spreading branches of a beautiful bur oak shaded the little stream where it gushed from the outcropping limestone4 ,do you want a drink8 asked ,susie1 taking the tin dipper which always hung by the spring4 ,thank you1 dear4 ,how cool it is6 ,it makes me think of the old spring in the hayfield where ,i used to work when ,i was a boy4 ,the rain has not made the spring run any faster1 said ,donald4 ,where does this water come from8 asked ,uncle ,robert4 ,from out of the ground1 said ,susie4 ,how does it get into the ground8 ,illustration3 ,the spring4 ,it's always there1 isn't it8 said ,susie4 ,the spring runs all the time4 ,i fill my pail here every day in the summer4 ,yes1 don't you remember when the wells all dried up last summer1 said ,frank1 that the spring was all right8 ,well1 then1 where has the water gone that fell to-day8 asked ,uncle ,robert4 ,most of it has run off into the creek and river1 said ,donald4 ,it would look just like a lake if it was an inch and a half deep all over the ground4 ,some of it has soaked into the ground1 said ,frank4 ,how deep down into the ground8 asked ,uncle ,robert4 ,down to ,china1 laughed ,donald4 ,how deep do you have to dig to find water--to ,china8 ,our wells are about thirty feet deep1 said ,frank4 ,in a dry time there's no water in them4 ,how is it when you have a long wet spell8 ,they are more than half full then4 ,have both wells the same depth8 ,i think so4 ,where does the water in the wells come from8 ,it is the rain that has soaked into the ground1 said ,frank4 ,how far down does it go8 ,it must go down till it finds some hard clay or rock that stops it1 said ,frank4 ,what does it do then8 ,then1 said ,frank slowly1 it must go along on top of the rock or clay4 ,when does it come out of the ground8 ,oh1 ,i see6 ,the rain goes down until it comes to that lime rock4 ,then it goes along the rock1 and comes out there1 said ,donald1 pointing to the spring4 ,does it always8 asked ,frank4 ,i have read of very deep wells that are bored down into the ground more than a thousand feet1 and when the augur strikes water the water comes right up to the top of the ground4 ,you are talking about artesian wells1 said ,uncle ,robert4 ,yes1 that is the name4 ,illustration3 ,section of hillside4 ,they had left the spring and were walking down toward the mouth of the creek4 ,the rain had swollen the little stream1 and the water was dark with dirt4 ,see how muddy the water is1 said ,susie4 ,the creek must bring down a lot of earth1 said ,frank4 ,there are ,joe and ,dick ,davis1 said ,donald1 pointing across the river4 ,i wonder what they are doing8 ,i'm going to see4 ,donald ran along to the mouth of the creek1 which he reached as the ,davis boys began to scramble down the steep bank to the edge of the river4 ,hello there6 called ,donald4 ,what are you fellows doing8 ,sticking in the mud1 replied ,joe ,davis1 holding up first one foot and then the other1 heavy with the stiff clay that hung to it4 ,why don't they go around by the path8 said ,susie1 coming up with ,frank and ,uncle ,robert4 ,they'll always take the short cut if there is one1 laughed ,frank4 ,come along over here6 he shouted4 ,all right1 sang out ,dick1 scraping the mud from his shoes4 ,an eddy in the stream just above the steep bank made a quiet place in the current4 ,here their boat was moored4 ,as they pushed out from the shore they were swept down the stream1 but a few strong pulls carried them beyond the swiftest part of the current1 and then they easily rowed back to the landing at the mouth of the creek1 where the ,leonards were waiting for them4 ,i wish our bank was low like this1 said ,joe as he leaped from the boat4 ,we have to go so far downstream before we find a low bank on our side4 ,i should think you'd rather walk a mile1 said ,susie1 looking at ,joe's shoes1 than come down that bank when it's so muddy4 ,humph6 we don't mind a little mud1 said ,dick1 wiping his feet on the grass4 ,you've brought some of your land over to us1 ,i see1 laughed ,uncle ,robert4 ,mr4 ,leonard will be obliged to you4 ,he is always glad when the soil is left on his side4 ,i don't see why it is1 said ,joe1 that our land is being cut away all the time and yours is getting bigger4 ,it isn't fair4 ,we can't help it1 ,joe1 said ,susie4 ,it's the river that does it4 ,you ask ,uncle ,robert4 ,he'll tell you all about it4 ,i can tell you how it is1 said ,donald4 ,you know how strong the current is over on your side8 ,well1 that's the reason your land is washed away4 ,the water flows slower here1 so it drops all the stuff it brings with it on our side4 ,see8 ,my6 said ,dick1 with a mischievous twinkle in his eyes1 doesn't he know a lot6 ,well1 it's so1 declared ,donald1 giving his head a nod4 ,you can see it yourself if you keep your eyes open4 ,my eyes are always open1 said ,dick1 but that doesn't keep our land4 ,you ought to have a creek1 said ,frank1 if you want your land to grow4 ,just look1 uncle1 what a lot of dirt has been left here4 ,it makes quite a delta1 doesn't it8 replied ,uncle ,robert4 ,sure enough1 said ,donald4 ,you remember the day of our picnic we were going to see if there was one here1 and we forgot it4 ,now you see where some of the dirt or silt that is brought down by the creek goes1 said ,uncle ,robert4 ,and all this must have been left here since the flood in the spring4 ,frank is right4 ,the creek is really building land all the time4 ,most of the dirt or--what did you call it--silt goes down the river1 doesn't it8 asked ,frank4 ,our land goes down the river1 said ,joe2 ,i've seen it4 ,and the river is building land for us1 said ,donald4 ,yes1 said ,uncle ,robert1 the river works all the time1 tearing down in some places and building up in others4 ,the clouds give us rain1 the rain goes down into the ground1 and then comes out and runs into the streams1 and then-- ,into the ocean1 said ,frank4 ,and then-- ,no one spoke4 ,and then it rises up from the ocean and comes back again in clouds4 ,did those clouds we had this morning come all the way from the ocean8 asked ,joe4 ,i don't see how they could come so far8 ,the clouds have swift wings to carry them1 replied ,uncle ,robert4 ,they travel very far without tiring4 ,the wind brings the clouds1 doesn't it1 uncle8 asked ,susie4 ,yes1 they come on the wings of the wind4 ,oh1 said ,joe1 ,i see4 ,there's father blowing the horn1 said ,dick4 ,we must go4 ,come again1 said ,uncle ,robert and the children together4 ,i wish we could hear more about the river1 said ,joe to ,frank as he helped them push off the boat4 ,come over again any day1 said ,frank4 ,uncle ,robert will tell you all about it4 ,i wish he was my uncle1 too1 said ,dick as they pulled out into the stream4 ,he isn't a bit stuck up and he knows a lot4 ,,chapter ,,xv4 ,,the ,,big ,,book4 ,please tell us another story from the ,big ,book1 begged ,susie as the family were all seated on the piazza one beautiful summer evening4 ,the great full moon1 like a ball of molten iron1 was rising in the east4 ,it plowed a silver path across the river4 ,fireflies glimmered and sparkled in the dusky shadows of the meadow and in and out of the garden shrubs4 ,the merry chirping of the crickets and the low hum of insect voices filled the air4 ,down by the creek the whip-poor-will told his one story over and over4 ,a story from the ,big ,book6 repeated ,uncle ,robert4 ,there are so many and they are all so wonderful4 ,ever since man was created he has read stories in the earth1 water1 and sky1 and in all living things4 ,everything he has found in ,nature helps him to live and grow wiser and better4 ,we could never understand printed books unless we studied the ,big ,book4 ,the more we read what ,god has written the more we shall want to read what other people have found out and put into printed books4 ,the true desire to read these books springs from our love and study of ,nature4 ,it was written for many years that the sun moved around the earth4 ,but ,copernicus studied the sun1 earth1 and stars anew1 and he showed that the printed books were wrong by proving that the earth moved around the sun4 ,galileo read the same story through the telescope that he made4 ,steam had always been a very common thing4 ,hot vapor had risen from heated water ever since fire was discovered1 but the real story of steam had not been read until ,watt sat long hours by a boiling teakettle4 ,then came the locomotive1 the railroad1 and mighty engines driving wheels that work for man4 ,wasn't that a good story to read from the ,big ,book6 said ,frank4 ,lightning had flashed and thunder rolled throughout the ages4 ,men feared1 wondered1 and worshiped that mighty hidden power4 ,franklin looked straight at the forked lightning and asked1 ',what are you8' ,the answer came in the telegraph that is fast making the nations of the earth one great family4 ,bell listened long and carefully to sounds1 and now ,i can talk from ,new ,york to my friends in ,chicago4 ,are not these stories from the ,big ,book as wonderful as miracles8 ,these are only a few of the many stories that have been read4 ,countless more will be read when children really open their eyes to the 'law of the ,lord that converteth the soul4' ,great men and great minds have road ,nature's revelation in the past1 but the time is coming when you and ,i and all children will read every day and hour the hidden things that surround us like light and press upon us like air4 ,the ,creator is writing the ,big ,book all the time for us--,his children4 ,should we not read what ,he says there8 ,the children did not understand all that ,uncle ,robert said1 yet they loved to listen4 ,we have found that our farm is a very interesting page of the ,book1 said ,mrs4 ,leonard4 ,yes1 that is the precious thing about it all4 ,whether we look1 or whether we listen1 ,we hear life murmur or see it glisten4 ,all eyes were gazing at the moon as it seemed to rise above the trees4 ,the great face of the man in the moon became distinct as he looked down upon the rolling earth4 ,a beautiful and wonderful world1 continued ,uncle ,robert1 but probably not a bit more wonderful than the countless worlds we see up there4 ,just think6 we are on a great round ball1 and it is moving on its axis from west to east toward the moon4 ,the moon1 you know1 does not really move over our heads as it seems to do4 ,the round earth rolls upon its axis1 and that makes the moon seem to rise higher and higher1 and then sink away below the western horizon4 ,to-morrow night it will come up in the east a little later1 said ,frank4 ,round and round we go upon our ball of earth4 ,the sun seems to rise and set just as the moon does1 but it is the world itself that makes the sun and moon seem to rise and set1 said ,uncle ,robert4 ,what is our earth made of8 asked ,donald4 ,just what you see before you1 answered ,uncle ,robert4 ,under our feet we have the ground1 the soil1 gravel1 sand1 and loam1 which is made of-- ,ground-up rock1 said ,frank4 ,and underneath the soil there is-- ,the solid rock1 said ,frank4 ,and underneath that8 asked ,mr4 ,leonard4 ,we do not know1 but it is quite certain the solid earth is made of ground-up rock and rock that may be ground4 ,the mills are all at work1 grinding all the time4 ,the mills6 said ,susie4 ,where are the mills8 ,i know one1 said ,donald4 ,the river is a great mill4 ,don't you remember about the pebbles8 ,and the glaciers are mills1 too1 said ,frank4 ,illustration3 ,glaciers on the ,coast of ,norway ,yes1 the rivers1 the ice rivers or glaciers1 the wind1 the frost1 heat and cold1 all grind masses of rock into bowlders1 pebbles1 and sand4 ,the rock has been ground so long ,i should think there would be nothing left but soil1 said ,frank4 ,you saw the limestone down by the spring8 asked ,uncle ,robert4 ,yes1 the children said together4 ,that limestone was once soft mud spread out upon the bottom of the ocean in shallow water4 ,how do you know that is so1 uncle8 questioned ,frank4 ,illustration3 ,fossil fish4 ,there are many proofs1 but the best proof is that in the limestone are found shells of animals that live in the sea1 said ,uncle ,robert4 ,fossils1 said ,mrs4 ,leonard4 ,yes1 fossils4 ,they are the remains of plants and animals that lived a very long time ago4 ,many rocks are almost entirely made of fossils4 ,fish and shells also have been covered with soft clay and left their imprints4 ,great beasts have walked in the mud1 and we now find their footprints in the hard stone4 ,coral--you have seen coral8--is often found in limestone4 ,it is made of the shells of little animals1 called the polyp1 which live in the sea4 ,illustration3 ,coral ,so you see that the firm ground under foot is made of rock1 some of which has been ground up over and over again4 ,but there is something else besides rock that makes the world ,water1 said ,donald promptly as he looked down upon the river4 ,yes1 the water is just as much a part of our world as the solid rock and the soil4 ,there is water in the soil and in the solid rock1 too4 ,it comes out to us in---- ,springs1 said ,donald4 ,water fills hollows in the earth---- ,ponds and lakes1 said ,frank4 ,water runs down the slopes-- ,streams1 said ,frank4 ,rivers1 said ,donald4 ,there is water in the air--mist1 fogs1 and clouds--and there is much water in the air which we can not see4 ,vapor8 asked ,frank4 ,sometimes water is so thin we can not see it1 and again it is so thick and hard that we may walk over it4 ,ice1 said ,susie4 ,tiny bits of vapor come together until they become so heavy that they fall to the ground4 ,raindrops1 said ,donald4 ,water is sometimes frozen in the clouds in beautiful white crystals1 and then they sail down to the earth4 ,snowflakes1 said ,susie4 ,sometimes drops start from the clouds and go through very cold air4 ,the cold air freezes them quickly1 and then they rattle on the roof and dash on the ground4 ,they cut the corn leaves and destroy the crops4 ,hailstones1 said ,donald4 ,oh1 said ,susie1 ,i saw a hailstone once as big as an egg4 ,the lakes are hollows in the ground filled with water4 ,there are many small hollows1 and some big ones1 but there is one so great that we may call it immense4 ,it is the largest hollow in the world--so large that it occupies three-fourths of the earth's surface4 ,illustration3 ,ocean islands ,the ocean1 said ,frank4 ,yes1 the ocean is only a great big hollow filled with water4 ,how deep is the ocean8 asked ,frank4 ,very deep in some places--deeper than the height of the highest mountains4 ,in others it is very shallow4 ,in some places bits and masses of land rise out of the ocean4 ,islands8 asked ,donald4 ,four great masses of land rise above the ocean level4 ,these immense rock masses are called-- ,continents1 said ,frank4 ,yes1 said ,uncle ,robert4 ,we live on one of them4 ,the continent of ,north ,america1 said ,donald4 ,our island rises right out of the river1 said ,susie4 ,rock and water make only a part of our world4 ,we live on the firm earth4 ,but we live in something4 ,indeed1 we live at the bottom of a great1 deep ocean1 deeper than the water ocean1 and broader than the rock and water surface taken all together4 ,we live at the bottom of an ocean6 said ,donald in surprise4 ,now you are joking1 ,uncle ,robert1 said ,susie4 ,if we lived on the bottom of an ocean we should all drown4 ,fish live in the ocean1 and we live in an ocean1 too--a very deep one1 how deep no one really knows4 ,it may be a hundred1 or hundreds of miles deep4 ,we see a part of the surface of the earth and of the water1 but no one has ever seen the surface of the mighty ocean in which we live4 ,susie and ,donald were puzzled4 ,frank's face lighted up as he said3 ,i think you mean the air1 ,uncle ,robert4 ,you are right1 ,frank4 ,the great ocean in which we live is the air1 or1 as it is called1 the atmosphere4 ,the atmosphere is just as much a part of our world as the rock and the water4 ,the rock we may call solid1 the water fluid1 and the air gaseous4 ,solid1 fluid1 gas4 ,how do we know that the atmosphere is so deep8 asked ,frank4 ,we do not know exactly1 but there are ways of proving that it is very1 very deep4 ,when people began to study the atmosphere they thought it extended about fifty miles from the surface of the earth4 ,now they are sure that it is much deeper4 ,we know that air has weight1 like soil and water4 ,it presses on us and everything else-- ,fifteen pounds to the square inch1 said ,donald4 ,we weigh the air with the--- ,barometer1 said ,susie4 ,it is heavier at the ocean level than it is on the tops of mountains4 ,we are sure that the higher we go up--- ,the less the air weighs1 said ,frank4 ,at the height of fifty miles it is thought to have little or no weight1 and so people believed that was as far as it extended4 ,but in time they discovered another way of measuring the atmosphere4 ,you have seen falling stars1 haven't you8 asked ,uncle ,robert4 ,illustration3 ,meteors4 ,oh1 yes1 said the three children together4 ,i saw a star fall1 so fast--just like a rocket4 ,then the light went out1 and ,i wondered where it went1 said ,susie4 ,falling stars are not stars at all1 though they look like them4 ,they are pieces of rock that break off from other worlds and whiz through space4 ,oh6 said ,susie4 ,outside of our atmosphere there may be nothing for these masses of rock to strike against1 but just as soon as they come into the air1 it tries to stop them4 ,the air is not strong enough to stop them1 but it grinds them up4 ,grinds them up6 exclaimed ,donald4 ,isn't that wonderful8 ,but1 uncle1 what makes them look just like fire8 ,if you put an axe or scythe on a dry grindstone and turn the crank1 what do you see8 ,sparks of fire1 said ,frank4 ,why do you put grease or oil upon the axles of your buggy8 ,to keep them from becoming hot and dry1 said ,frank4 ,one time when father and ,i were on a train there was a hot box1 and we had to stop to cool it4 ,the heat and the sparks of fire are caused by one body rubbing against another4 ,the faster they move1 the greater the heat4 ,this rubbing is called friction4 ,there was a time1 said ,mr4 ,leonard1 when fires were started by rubbing two pieces of wood together4 ,some ,indians do so now4 ,then the great pieces of rock rub against the air when they whiz through it1 and that makes the sparks8 asked ,frank4 ,you are right4 ,we can see the blaze of fire caused by the friction4 ,i should think the rocks would fall on us and kill us1 said ,donald4 ,most of them are probably ground up into bits of dust before they reach the ground4 ,some of them1 indeed1 do strike the ground1 and very large ones bury themselves deep in the earth4 ,when we go to the ,field ,columbian ,museum1 in ,chicago1 we shall see these visitors from other worlds4 ,they are called meteoric stones1 or meteorites4 ,when they are in the air we call them meteors4 ,i am going to watch the next one ,i see1 said ,susie4 ,they fly so fast that you hardly see them before they are gone1 said ,donald4 ,men who study the heavens tell of the depth of the atmosphere by the angle the meteor makes in falling1 but perhaps you can not understand that now4 ,so you see1 children1 we live on the bottom of a great ocean of air1 and that air1 or atmosphere1 is a part of our world--the outside part4 ,how plain it all is1 said ,mrs4 ,leonard1 when we think of it this way6 ,now we have the land and the water1 said ,uncle ,robert4 ,and the atmosphere1 put in ,donald4 ,and they are all right here close to us4 ,here is the land with its hollows1 and there1 pointing to the river glistening in the moonlight1 is the water1 and-- ,you can't see the air1 said ,donald4 ,we can feel it1 anyway1 said ,susie4 ,how large is the earth1 uncle8 asked ,frank4 ,eight thousand miles through it and twenty-five thousand miles around it1 answered ,uncle ,robert4 ,but1 uncle1 is it all solid rock for eight thousand miles8 ,no one knows4 ,the rocky outside of the ball is called the crust of the earth4 ,miners have dug down nearly four thousand feet1 and makers of artesian wells have bored still farther4 ,they always find rock4 ,i wonder how far four thousand feet would be1 said ,donald4 ,a little over three quarters of a mile1 said ,mr4 ,leonard4 ,the farther they go down into the crust of the earth1 the warmer they find it4 ,i have been down in a mine thirty-two hundred feet1 and it was very hot4 ,no one could have lived there if cool air had not been brought down from the surface4 ,some people have thought that inside the crust of the earth the rock is all a molten mass1 like melted iron4 ,you have read about volcanoes1 and of the lava that is thrown out of them8 ,does that come out of the inside of the earth8 asked ,donald4 ,illustration3 ,down in a ,gold ,mine ,it comes from somewhere in the earth4 ,some men give their whole lives to the study of these questions1 but you know they can not see beneath the crust of the earth4 ,it is thought by some that the weight of the crust would keep the center of the earth a solid mass4 ,so you see there are still many questions unsettled4 ,we know that the crust is moving up and down all the time4 ,oh1 ,i hope the land won't rise here6 said ,susie4 ,you wouldn't know it1 ,susie1 if it did1 said ,uncle ,robert1 laughing4 ,unless there was an earthquake1 said ,frank4 ,or a volcano1 said ,donald4 ,i'd like to see one4 ,i would like to see the ocean1 said ,frank4 ,it must be grand to stand on the shore and look way off and not see anything but water4 ,it is a grand sight1 ,frank4 ,i have sat on the beach many a time and watched the waves roll in1 and thought of the wonderful work the ocean is doing4 ,you know it is the great reservoir that supplies all the land with water4 ,illustration3 ,view of the ,ocean ,the heat of the sun lifts the water up1 or evaporates it4 ,the vapor that makes the clouds rises into the air4 ,the winds blow the vapor many long miles1 and some of the clouds come right over our heads4 ,the cold air draws the little bits of vapor together and makes the clouds heavy1 and down they fall upon the earth as drops of rain4 ,some of the rain runs directly into the streams4 ,some of the rain water sinks down into the earth2 in the gravel it sinks fast2 in the sand it sinks slower2 and in the loam1 clay1 and rock it sinks very slowly indeed4 ,the water in the ground dissolves the rock or the loose earth into little particles so fine that the tiny roots1 or root hairs1 drink them up1 and so the rock furnishes a part of the nourishment1 or food1 of plants4 ,without the water that the clouds bring no plant could grow4 ,it gives life and growth to everything that lives1 and then sinks deep into the earth4 ,it comes out of the ground again in springs1 and flows away in rivulets1 brooks1 creeks1 and rivers--away1 and away1 back to the ocean again4 ,on its way to the ocean it wears down the land1 carries silt from place to place1 spreads it out on beaches1 sand bars1 bottom lands1 deltas1 and on the bottom of shallow places in the ocean4 ,isn't it strange how everything changes1 and how all the changes help us8 said ,frank thoughtfully4 ,yes1 ,frank1 it is wonderful how the ,creator of all things is constantly moving earth1 air1 and water1 and1 as you say1 making all these changes to help man4 ,it is the ,big ,book that tells us of this marvelous world of ours and of other worlds as well4 ,it lies open before us for us to read every day4 ,god has created and is still creating our home1 the dwelling place of ,his children4 ,we must study ,him1 my dear children1 in all ,he has made4 ,we must learn of ,his works in order to use everything to make man happier1 better1 and more useful4 ,mr4 ,leonard1 who had been listening very attentively to the story1 said1 as his face lighted with a happy smile3 ,i never thought of it all in that way before4 ,every day1 in all our work on the farm and in the house--indeed1 wherever we may be--we should learn new and beautiful revelations from our ,heavenly ,father2 how much ,he is constantly giving us1 and how thankful we should be4 ,the moon had risen to its full glory over the earth4 ,the waters of the river glistened4 ,the trees1 cornfields1 and meadows were peaceful and grand1 as though they1 too1 felt the power of the glorious light4 ,susie put her brown arms around her mother's neck and kissed her good-night4 ,oh1 how ,i love the ,big ,book6 she said4 ,i wish ,i could read it as all those great men have read it1 said ,frank4 ,so do ,i1 said ,donald4 ',day unto day uttereth speech1 and night unto night sheweth knowledge1' mused the mother as her loved ones went to bed with sweet thoughts of a beautiful world and a loving ,god4
