+UNCLE ROBERT'S VISIT
+
+BY FRANCIS W. PARKER AND NELLIE LATHROP HELM
+
+
+
+
+PREFACE BY THE EDITOR OF THE HOME-READING BOOKS.
+
+
+The publishers take pleasure in offering to the public, in their
+Home-Reading Series, some books relating to the farm and other aspects
+of country life as the center of interest, written by Colonel Francis W.
+Parker, the President of the famous Cook County Normal School, in
+Chicago. 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 schoolroom. 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 purposes.
+
+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 study. 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 experience. Almost all of the school reforms that have been
+proposed in the past one hundred years have moved in this line. The
+effort to seize upon the child's interest and make it the agency for
+progress has formed the essential feature in each. In this reform
+movement Colonel Parker has made himself one of the chief influences.
+
+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 classes. Children in
+various degrees of advancement from ABC's to higher arithmetic, and
+yet numbering only ten, twenty, or thirty in all, are enrolled under one
+teacher. Most branches of study could muster only one or two pupils in
+each class: Five to ten minutes a day is all that can be allowed in such
+cases for a recitation. No thoroughness of instruction on the part of
+the teacher is possible, nor is there much improvement to be expected in
+the method of instruction where classes can not be formed. The
+benefactor of the country school therefore looks to other devices than
+class instruction, 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 district, encourage home study initiate practical
+experiments.
+
+It is expected that the teacher, besides his daily register in which he
+records the names and attendance of his own pupils, 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 farm, and that he will endeavor by
+proper means to persuade them to enter upon well-planned courses of
+reading. Occasional meetings in the evening at central places, or on
+some afternoons of the week at the schoolhouse itself, will furnish
+occasions for the discussion of the contents of the books that have been
+read, and experiments will be suggested in the way of verifying the
+theories advanced in them.
+
+Not only can the mind of the country youth be broadened and enlarged in
+the direction of literature and art, and of science and history, but it
+can be made more practical by focusing it upon the problems connected
+with the agriculture and manufactures of the district.
+
+This indicates a career of usefulness for the ambitious teacher of a
+rural school. There is a large field for the discipline of the directive
+power open even for the humblest of teachers in the land.
+
+These books of Colonel Parker, if read by the school children, and
+especially by the elder youth who have left school, will suggest a great
+variety of ways in which real mental growth and increase of practical
+power may be obtained. 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-men, and at the same time be taught how to verify and extend his
+book knowledge by investigations on his environment. This having been
+achieved by the school, nothing except his indolence, or, to give it a
+better name, want of enterprise, prevents the individual citizen from
+growing intellectually and practically throughout his whole life.

+
+AUTHOR'S PREFACE
+
+
+Fortunate are the children whose early years are spent in the country in
+close contact with the boundless riches which Nature bestows.
+
+Amid these environments instinct and spontaneity do a marvelous work in
+the growing minds of children, arousing and sustaining varied and
+various interests, enhancing mental activities, and furnishing an
+educative outlet for lively energies.
+
+Most fortunate are they to whom, at the moment when the unconscious
+teachings of Nature need to be supplemented by thoughtful suggestion,
+wise leadings, and judicious instruction, there comes one with a deep
+and loving sympathy with child life, an active interest in all that
+interests them, and a profound respect for all that children do well and
+for all that they know.
+
+Such an one is Uncle Robert. He comes to the children at just the right
+moment. He directs the sweet strong streams of their lives onward into a
+channel of earnest inquiry and exalted labor, which is ever broadening
+and deepening.
+
+Uncle Robert's aim in education is to fill each day with acts which make
+home better, the community better, mankind better; to take from God's
+bounteous and boundless store of truth and convert it into human life by
+using it. His method is simple and direct, founded upon the firm rock,
+Common Sense. It may be briefly stated as follows:
+
+1. A strong belief in the sacredness of work--that work which inspires
+thought, strengthens the body as well as the mind, and develops the
+feeling of usefulness.
+
+2. The images the children have acquired and the inferences they have
+made are used as stepping stones to higher and broader views.
+
+3. So far as it is possible, each child is to discover facts for himself
+and make original inferences.
+
+4. He understands the limits of children's power to observe and the
+demand on their part for glimpses into, to them, the great unknown. So
+he tells them stories of those things which lie beyond their horizon, in
+order to excite their wonder, intensify their love for the objects that
+surround them, and make them more careful observers. In this way a
+hunger and thirst for books is created.
+
+5. He watches carefully the interests of each child, adapting his
+teachings to the differences in age and personality.
+
+6. 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 confidence.
+
+7. He makes farm work and farm life full of intensely interesting
+problems, 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 beyond.
+
+Uncle Robert's enthusiasm has for its prime impulse a boundless faith in
+human progress, brought about by a knowledge of childhood and its
+possibilities.
+
+He believes that every normal child, under wise and loving guidance, may
+become useful to his fellows, moral in character, strong in intellect,
+with a body which is an efficient instrument of the soul; in other
+words, truly educated.
+
+Those who read Uncle Robert's Visit should read through the eyes of
+Susie, Donald, and Frank. The reading, so far as possible, should be
+accompanied by personal observation, investigation, and experiment.

+
+TOPICAL ANALYSIS OF UNCLE ROBERT'S VISIT.
+
+NOTE.--The direct study of earth, air, and water involves the study of
+plant, animal, and human life. Popular opinion has given the name of
+geography to these correlated subjects.
+
+
+CHAPTER I.--UNCLE ROBERT'S COMING.
+
+The value of the children's knowledge of the farm is warmly recognized
+by Uncle Robert. The children feel his sympathy for their work, and
+through it are led to closer study and investigation. The feeling that
+everything they may see and do is of importance, exalts their daily
+life.
+
+Encourage children to describe the farms on which they live. In such
+descriptions should come plant and animal life, and the means and
+processes of farm work. Extend these descriptions to other farms and to
+any landscapes which the children have observed.
+
+CHAPTER II.--FRANK DRAWS A MAP OF THE FARM.
+
+All children love to draw, and they will draw with great confidence and
+boldness unless their critical faculty outruns their skill. Modeling and
+painting may be very profitably introduced at an early age. Frank's
+efforts in drawing strengthened his images of the landscape.
+
+Arithmetic has a very important place in farm life. It may be used in
+many ways in forming habits of accuracy and exactness.
+
+CHAPTER III.--THE NEW THERMOMETER.
+
+The children have their first lesson on the agent of all physical
+movement and change in organic and inorganic matter. The simple
+experiments suggested should be continued and enlarged, thus beginning a
+life study of a subject which is practically unlimited in its importance
+to man.
+
+CHAPTER IV.--WITH THE ANIMALS.
+
+Children look upon animals as their particular friends and
+acquaintances. They talk to them and believe that the animals understand
+them. A desire to know the habits and habitats of animals is among their
+strongest interests. By a little wise direction, this interest may be so
+enhanced as to form a substantial beginning of the study of zoology.
+
+CHAPTER V.--IN THE FLOWER GARDEN.
+
+Children worship flowers. Probably there are no objects on earth so
+universally loved by little folks as buds and flowers. Children seek
+eagerly for flowers by the roadside, in the pastures, fields, and woods.
+This love, like all instincts, should be carefully cultivated.
+
+Children may easily be led to study the forms, colors, and habits of
+plants. They will always take the keenest interest in the mystery of
+seeds and shoots, of roots and growing leaves, _if there is a teacher
+to direct them_.
+
+CHAPTER VI.--SUNLIGHT AND SHADOW.
+
+We have heat again, and now as an elementary lesson in the distribution
+of sunshine. Children love to observe continual changes. The shadow is
+an object of interest. It has an element of mystery about it which
+borders upon the supernatural. Children observe spontaneously the long
+shadows of morning and the lengthening shadows of the descending sun.
+Most farm boys can tell the moment of noon by their shadows.
+
+These are all steps in the more difficult problems of lengthening and
+shortening shadows that mark the changing seasons, and that lead to the
+theories of the earth's rotation and revolution. Day by day children
+should note the changes of slant upon the shadow stick which they can
+easily make for themselves.
+
+CHAPTER VII.--THE BAROMETER.
+
+Our little friends have their first lesson concerning one of the three
+great envelopes of the earth-the atmosphere. The knowledge that air has
+weight does not often come by unaided intuition. The initial experiments
+may be made very interesting and profitable. The United States Weather
+Reports are an excellent means for the home study of geography.
+
+CHAPTER VIII.--A WALK IN THE WOODS.
+
+"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 forest. Trees well
+arranged make many farmhouses beautiful. Trees by the roadside add much
+beauty to the landscape and afford places of rest to the traveler.
+
+Forests mean moisture to the soil. Their leaves and roots make the best
+reservoirs for water, to be given out when needed by the growing crops.
+The forests are full of lessons for the children and the experienced
+scientist.
+
+CHAPTER IX.--THE BIRDS AND THE FLOWERS.
+
+The knowledge of a farm child is quite extensive, and generally neither
+the child nor the parent has any suspicion that such knowledge is of any
+appreciable value in education. 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 winter, and those who rest there in their
+migrating flight; to know also the names, the plumage, the habits of all
+the birds; and to know the nests and nesting places of those who make
+the farm their summer home.
+
+All this study cultivates the child's sense of the beautiful. There is
+no better color study in the world than that which springs from
+discriminating love of flowers and of the plumage of birds.
+Such study creates a kindly feeling toward both animals and plants on
+the part of the child. It exercises a strong moral power over him.
+
+CHAPTER X.--THE THUNDERSHOWER.
+
+A thundershower is always a phenomenon of interest and often of fear on
+the part of children. The clouds of the cumulus form, the rolling of
+thunder, the lightning flashes, the rushing wind, and the pouring rain
+are full of important lessons. Fear vanishes as knowledge comes. In the
+thundershower is the question of the distribution of moisture over the
+earth's surface, the question of the nature and use of clouds, the
+movement of the air and wind, the condensation of vapor, and the
+marvelous powers of electricity.
+
+CHAPTER XI.--THE VILLAGE.
+
+Geography should ever be in the closest touch with the human side.
+Nature does a marvelous work, but Nature without society is like a vast
+storehouse of treasure without a demand for its use. The one weak point
+in farm life is the lack of opportunity for contact with society.
+
+CHAPTER XII.--A DAY ON THE RIVER.
+
+A river, creek, lake--in fact, any body of water--is a source of
+perpetual delight to children. Frank, Donald, and Susie have had the
+river and creek before them all their lives. Now, under Uncle Robert's
+teaching, the river will mean very much more to them. They take their
+first lessons in the work of streams in carving and shaping the earth's
+surface. The pebbles on the beach and the large, rounded stones will
+soon have stories of the distant past to tell them. The "Big Book" is
+opened to them, and they read the stories directly from its pages.
+
+CHAPTER XIII.--A RAINY DAY.
+
+The children get closer to the question of moisture, its use, and
+distribution. The rain gauge helps them to measure the rainfall. Then
+comes the problem of where the water goes after it reaches the ground.
+"How far down does some of it go?" "When and where does it come out of
+the ground?"
+
+Arithmetic is brought in in measuring the rainfall and its distribution.
+
+CHAPTER XIV.--THE WALK AFTER THE RAIN.
+
+The problems in Chapter XIII move toward their solution, and new
+questions are opened. The gully tells of the wearing of the water, and
+foretells a river valley. The spring helps in the question of
+underground water. The flowing river quickens the imagination in the
+direction of the great ocean.
+
+CHAPTER XV.--THE BIG BOOK.
+
+This chapter should be read by parents to the children, as many
+sentences need expansion and explanation. Hints are given of great
+things which lie beyond the child's horizon. Discoveries that have
+changed mankind are referred to.
+
+Children's permanent interests are the keynotes of instruction and the
+infallible guides of the teacher. To continue and sustain their
+spontaneous observation and desire for investigation leads directly to
+the study of the best books, and lays the basis for a thorough and
+profound study of God's universe.
+
+
+
+
+CHAPTER I.
+
+UNCLE ROBERT'S COMING.
+
+
+Uncle Robert was coming. His letter, telling when they should expect
+him, had been received a week before. Every day since had been full of
+talks and plans for his visit, and now the day was come. Everything was
+ready.
+
+Frank and Donald had harnessed Nell, the old white horse, to the little
+spring wagon, and had driven to the village to meet the train which was
+to bring Uncle Robert from New York.
+
+Susie, in her prettiest white apron, ran out of the house every few
+minutes, to be the first to see them when they should come along the
+road.
+
+Mrs. Leonard was putting finishing touches here and there. She went into
+the kitchen to give Jane a last direction about the supper. Then she
+went to the east room upstairs, Uncle Robert's room, to be sure that
+everything was just as she knew he would like it.
+
+Susie followed her mother, to see if the violets in the glass on his
+table were still bright and fresh. She had gathered them herself in the
+woods that morning.
+
+"There they come!" she cried. "I hear the wagon crossing the bridge at
+the creek!"
+
+She ran quickly downstairs and out upon the piazza. A moment more, and
+the wagon turned in at the gate.
+
+"Mother, mother," called Susie, "they're here!"
+
+But Mrs. Leonard was already beside her. Her pleasant face glowed with a
+happy smile as Frank drew rein before the door.
+
+Then such a time!
+
+Uncle Robert sprang from the seat beside Frank, hugged Mrs. Leonard,
+then Susie, then both together.
+
+Donald, who was seated in the back of the wagon on Uncle Robert's trunk,
+turned a handspring, landed on his feet somehow or other, and stood
+grinning at Susie.
+
+Mr. Leonard had also heard the sound of the wheels. He hurried from the
+barn, calling Peter to come and help him carry Uncle Robert's trunk
+upstairs.
+
+Jane came to the door of the dining-room, eager to see the Uncle Robert
+of whom she had heard so much. Then, with a nod of her head, she ran
+back, slipped the pan of biscuits into the oven, and put the kettle on
+to boil.
+
+Uncle Robert had come! Everybody was happy. No one more so than Uncle
+Robert himself.
+
+"Now, this is good," he said, when at length they were seated around the
+supper table. "I feel at home already. Susie, did those violets on my
+table grow in your garden?"
+
+[Illustration: Violets.]
+
+"Oh, no," replied Susie. "I found them in the woods by the creek. And
+the buttercups, didn't you see them in the glass, too?"
+
+"Buttercups so early ?" asked Uncle Robert. "Oh, yes, the low ones do
+come early. You must take me down where they grow some day."
+
+"We'll go to-morrow," said Susie.
+
+Uncle Robert smiled at the eager little face, and, turning to Mr.
+Leonard, said:
+
+"Frank tells me the farm is looking well this spring."
+
+"Yes, it looks fairly well," replied Mr. Leonard. "The seed is all in
+but the corn. That is a little late. The water on the bottom land stayed
+longer than usual this year."
+
+"Peter thinks we can start the planting to-morrow," said Frank.
+
+"Yes," replied his father, "I think so, too."
+
+When supper was over they all went out on the side porch. The sun was
+setting. The air was soft and spring-like. The lilacs along the fence
+filled the air with fragrance.
+
+"Don't you want to see Susie's garden, Robert?" asked Mrs. Leonard,
+
+"Yes, indeed," said Uncle Robert. "Susie wrote me some nice little
+letters about that garden."
+
+As they walked along the narrow paths Susie showed him where the seeds
+were already planted, and told him what she thought she would have in
+the other beds.
+
+"This is phlox," said Susie, leading Uncle Robert by the hand; "and
+marigolds are here, and sweet peas over there by the fence. That place
+between mother's garden and mine is filled with rosebushes, syringas,
+and hollyhocks."
+
+"I still call the vegetable garden mine, but the boys do most of the
+work," said Mrs. Leonard. "That big bush at the end of the row is an
+elder."
+
+"This is to be my pansy bed," said Susie. "The pansies are not set out
+yet. They are growing in a box in the kitchen window. I love them best
+of all. Don't they look like funny little faces in bonnets?"
+
+[Illustration: Pansies.]
+
+"That is what the Germans think, Susie," said Uncle Robert, laughing.
+"They call them 'little stepmothers.'"
+
+"I think it will be safe to put them out soon, Susie," said Mrs.
+Leonard.
+
+"Mother," called Donald from the vegetable garden, "the lettuce and
+radishes are growing finely, and here's a bean. Oh, there are lots of
+them just putting their heads through!"
+
+They all went over to look at the beans, and then walked down to the end
+of the garden where the currant and gooseberry bushes grew.
+
+"Oh, uncle," exclaimed Susie, "I wish you had come in time to see the
+trees in blossom! They were all pink and white. It was just lovely! only
+the flowers stayed such a little while."
+
+"I think Susie lived in the orchard those days," said Mrs. Leonard,
+smiling. "If I wanted her I was very sure to find her there."
+
+"I don't blame Susie," said Uncle Robert. "I would have stayed, too.
+There is nothing sweeter than apple blossoms. But you have other fruits
+besides apples, haven't you?"
+
+[Illustration: Apple Blossoms.]
+
+"Oh, yes," said Frank, who had just come from the barn, where he had
+gone after supper with his father. "There are pears and cherries and a
+few peach trees. But peaches don't do well here."
+
+"The blossoms are lovely," said Susie.
+
+"I believe Susie cares more for the flowers than she does for the
+fruit," said Donald. "I don't. I like the fruit, and plenty of it."
+
+"How many kinds of apples have you?" asked Uncle Robert.
+
+"About ten," replied Frank. "But father budded quite a number last year.
+The twigs came from Kansas."
+
+"They have fine apples in Kansas some years," said Uncle Robert. "I
+wonder if the budding is done as it was when I was a boy on the farm
+in New England."
+
+"This is the way father did it," said Frank. "First he cut a little
+piece of the bark off the twig with the bud on it. He had to do it very
+carefully with a sharp knife. Then he cut the bark on the branch of the
+tree like the letter T. He laid it back, and slipped the piece of bark
+with the bud on under it. Then he bound it all up with soft cotton, and
+left it to take care of itself."
+
+"Did it?" asked Uncle Robert.
+
+"Yes," answered Donald. "In a few weeks we took the binding off, and the
+bark had all grown together around the little bud."
+
+[Illustration: Budding]
+
+"There were ever so many of them," said Susie, "and they were all
+alike."
+
+"I wish they would hurry up and have some apples on them," said Donald.
+"If they're better than some we had last year, they'll be pretty good.
+
+"Come, children," said Mrs. Leonard. "It is getting damp. I think we'd
+better go in now."
+
+
+
+
+CHAPTER II.
+
+FRANK DRAWS A MAP OF THE FARM.
+
+
+After the lamps were lighted and they were all gathered in the
+sitting-room Uncle Robert began asking the children about the farm.
+
+"What do you raise besides corn?" he asked.
+
+"Wheat, oats, rye, and potatoes," said Frank. "Then we have the hay
+fields and the pasture. The woods we drove through coming from town
+belong to us too."
+
+"The house faces east, doesn't it?" said Uncle Robert. "That would make
+the woods north. Where are all these other fields?"
+
+"Back of the barn and the other side of the orchard," said Donald.
+
+"Can't some one show me on paper how it is?" asked Uncle Robert. "I
+don't mean make a picture, but just a plan of it."
+
+"Well, I can try," said Frank. "I know just how it is really, but I
+don't know that I can get it right."
+
+Frank found paper and pencil and set to work, while the rest gathered
+eagerly around and looked on.
+
+"This is the river," he said. "There's a big curve in it along our farm.
+The road runs along the top of the slope, and this is where the house
+is."
+
+"What lies between the house and the river?" asked Uncle Robert.
+
+"The big cornfield," said Frank. "That's where we are going to plant
+to-morrow if it is a pleasant day. And right here, in the corner by the
+woods, is the spring."
+
+"The water comes right out of the ground," said Susie; "and it is as
+cold as ice."
+
+"Here," said Frank, "is the wood. You know we drove through it this
+afternoon. The woods are on both sides of the creek."
+
+"See the crooked line he makes for the creek," said Donald.
+
+"That is where the violets and buttercups grow, uncle," said Susie,
+pointing to the map.
+
+"Where does the creek come from?" asked Uncle Robert.
+
+"There's a pond away back in the woods," said Donald. "It comes from
+that; but it is a swamp part of the year."
+
+"The cat-tails grow there," said Susie.
+
+"Well," said Uncle Robert, "the house, the cornfield, and the woods--is
+that all of the farm?"
+
+"Oh, no!" said Frank. "It is low along the river, but back of the
+cornfield it gets higher, and that's where the grapes are. On this side
+of the road is the orchard; and here, between the orchard and the woods,
+come in the yard and garden."
+
+"Don't leave out the barnyard," said Donald.
+
+"What's back of the barn?" asked Uncle Robert.
+
+"The field of timothy; and next to it is the clover field. That is as
+far as the farm goes that way."
+
+[Illustration: CLOVER TIMOTHY WHEAT OATS RYE]
+
+"The wheat field is on the other side of the timothy, Frank," said
+Donald, "and the oats between that and the road, beside the orchard."
+
+"Put in the potatoes along the road," said Susie.
+
+"Now all we have left is the rye field over in the corner," said Donald.
+
+"That is the way it is this year," said Mr. Leonard, who sat with his
+paper in his hand. But the paper was unread. He found the group around
+the table much more interesting.
+
+"Now it is all done," said Susie, hopping about on one foot. "Isn't it
+fun? Let's draw the garden. I can do it."
+
+"All right," said Uncle Robert, "you shall; but I think we'd better
+finish the farm first. Who can tell how many acres there are in each of
+these lots?"
+
+"I know there are twenty in the timothy meadow," said Donald, "because
+father always calls it the twenty-acre lot."
+
+"Write it down on the map, Frank," said Uncle Robert. "How much in the
+clover field?"
+
+"It seems about half as large as the timothy meadow," said Frank.
+
+"That's right," said Mr. Leonard; "it is."
+
+"There are twenty acres in the wood lot, aren't there, father?" asked
+Frank. "It isn't quite so wide, but it is longer than the timothy
+meadow."
+
+"Yes," said Mr. Leonard, "there are twenty acres there; and it is as
+fine woodland as any I know."
+
+"There are ten acres in the orchard," said Frank; "and the cornfield is
+the largest of all."
+
+"That must be thirty acres," said Donald. "I remember when father made
+the pasture smaller, so that we could have more corn."
+
+"Yes," said Frank; "and that left ten in the pasture. I remember. And
+there are fifteen acres each in oats, wheat, and rye; but I don't know
+how large the potato field is. It is smaller than the others, though--it
+must be about ten."
+
+"Right again," said Mr. Leonard.
+
+[Illustration: (figures, addition, subtraction)]
+
+"Now we have it all but the yard and garden," said Uncle Robert. "Does
+any one know how much land they cover?"
+
+The father and mother looked on smiling, but said nothing.
+
+"It's all the rest of the farm, anyhow," said Susie.
+
+"Oh, I know how to find out," said Frank. "We know the whole farm is one
+hundred and sixty acres. We can add all these figures, and the
+difference between that and one hundred and sixty will be what's in the
+yard and garden."
+
+So he added all the numbers together and found them to be one hundred
+and fifty-five.
+
+"Yes," exclaimed Donald; "and five more would make it one hundred and
+sixty."
+
+"Then there must be five acres in the yard and garden." said Susie,
+"Write it down. Frank."
+
+"There," said Frank, looking at his work with
+some pride. "It's all in. Now shall I draw it again and make the lines
+straighter?"
+
+[Illustration: Map of the farm.]
+
+"Oh, no; this tells the story very well," said Uncle Robert. "The next
+time we will measure it off, and make it more carefully."
+
+"Not so bad," said Mr. Leonard, as Frank showed him the drawing.
+
+"I think it is very good for a first time," said Mrs. Leonard, with an
+encouraging smile. "With a little practice, my boy, I believe you would
+draw well."
+
+"Mother always believes we can do things," said Frank, laughing.
+
+"Tell me more about the river," said Uncle Robert.
+
+"Our side is bottom land," said Frank; "but across the river the bank is
+high and steep. Farther down it is just the other way. The steep bank is
+on this side, and the low land is opposite."
+
+"The river bends the other way down there," said Donald.
+
+"I see," said Uncle Robert. "How high is the bank?"
+
+"I don't know," answered Frank. "How high is it, father?"
+
+"About twenty feet," said Mr. Leonard.
+
+"Do you go on the river much?" asked Uncle Robert.
+
+"Oh, yes," said Donald. "We have an old boat, and we have been miles on
+it."
+
+"That is, downstream," said Frank. "We have never taken the boat up the
+river beyond the village, on account of the milldam."
+
+"There's an island in the river," said Susie, "between here and the
+village. We have been there."
+
+"How large an island is it?" asked Uncle Robert--"large enough to have
+a picnic there while I am here?"
+
+"Oh, yes," said Susie. "It's just the loveliest place for a picnic!
+There are trees all over it, and all kinds of wild flowers."
+
+"Can't you extend your map, Frank, so as to put in the river to the
+village, showing the milldam and the island?" suggested Uncle Robert.
+
+"You might draw it this way, too," said Donald, "and show how the river
+bends the other way down here."
+
+"Now I want to draw my garden," said Susie, when Frank had finished.
+
+Just then the clock on the kitchen shelf struck loudly.
+
+"It's bedtime now, dear," said Mrs. Leonard. "Can't you draw your garden
+to-morrow?"
+
+"We'll plant those pansies to-morrow," said Uncle Robert, "and see what
+can be put in all the other beds. Then we'll draw it, and tell just where
+everything is."
+
+So Susie went to bed happy, and Frank and Donald soon followed. And all
+were glad that Uncle Robert was really come.
+
+
+
+
+CHAPTER III.
+
+THE NEW THERMOMETER.
+
+
+The next morning as they left the breakfast table Donald said:
+
+"It's going to be warmer to-day."
+
+"I think not," said Frank. "When I went to the barn it seemed quite
+cool."
+
+"What do you think, Susie?" asked Uncle Robert.
+
+"It was cool under the trees when I went to the spring for a pitcher of
+water," said Susie, "but it seemed rather warm in the sun. I think it is
+a lovely morning."
+
+"What makes it warm?" asked Uncle Robert.
+
+"Why, the sun," replied Donald, looking rather surprised at such a
+question.
+
+"But does the sun make it warm in the winter?" asked Uncle Robert.
+
+"The sun is nearer the earth in spring and summer," said Frank
+confidently.
+
+"You are mistaken," said Uncle Robert. "The sun is farther from us in
+summer than it is in winter."
+
+"But it's almost over our heads in summer," said Frank. "How can it be
+farther away?"
+
+"The story of the warmth that the sun gives us is not told by
+distance," said Uncle Robert, "but by the length of the shadows at noon."
+
+"How is that?" asked Donald.
+
+"When is your shadow the longest?" asked Uncle Robert.
+
+"In the evening," said Donald.
+
+"In the morning," said Susie.
+
+"When is your shadow the shortest?"
+
+"At noon!" they all shouted.
+
+"When is it coolest?"
+
+"Morning," they replied together.
+
+"When is it warmest?"
+
+"Noon," said Susie quickly.
+
+"Now you are wrong," said Frank. "It is often warmer at one or two
+o'clock."
+
+"Frank is right," said Uncle Robert. "How can we tell just how warm it
+is at any time?"
+
+"If we had a thermometer," said Donald, "that would tell, but we
+haven't."
+
+"There's one at the post office," said Frank, "but I never saw any one
+look at it unless it was very cold or very hot."
+
+"Perhaps we can find one nearer than the post office," said Uncle
+Robert. "Susie, would you know one if you saw it?"
+
+Susie shook her head.
+
+"I would," said Donald.
+
+"Well," said Uncle Robert, "please go to my room, and if you find a
+thermometer bring it to me."
+
+Donald soon returned, and when Susie saw what he had in his hand she
+exclaimed:
+
+"Is that a thermometer? I never saw anything like that at the post
+office."
+
+"Well, I should think not," said Donald. "This isn't much like the
+old thing they have up there."
+
+"What does it say?" asked Uncle Robert.
+
+"Sixty-eight degrees above zero," said Frank, taking the thermometer in
+his hand.
+
+[Illustration: Thermometer.]
+
+"That isn't cold, is it, uncle?" asked Donald.
+
+"That's just right for the house," said Uncle Robert. "How is it out of
+doors?"
+
+"Let's take it out and see," said Frank.
+
+Out on the porch they went and eagerly watched the thermometer.
+
+"It's moving--it's going down!" cried Donald.
+
+"I'll hang it on this nail," said Frank.
+
+"When they looked again Donald said:
+
+"It's fifty-six now."
+
+"How much colder is it than it was in the house?" asked Uncle Robert.
+
+"Twelve degrees," said Frank, counting up the column.
+
+"Oh, let's take it in by the stove," said Susie, "and see how far it
+will go up."
+
+"What makes you think it will go up by the stove?" asked Uncle Robert.
+
+"Well," answered Susie, "if it goes down when it is cold I should think
+it would go up when it is warm."
+
+Susie took the little instrument, and, going into the kitchen, held it
+close to the stove.
+
+"Come," she called, "it is going up already. See!"
+
+"How fast it moves!" said Donald. "Hold it close to the stove, Susie.
+Maybe it will go to the very top."
+
+"Let us put it in cold water," said Frank. "It won't hurt the
+thermometer, will it?"
+
+"Not at all," was the reply. "Try it."
+
+So they held it in the bucket of cold spring water.
+
+"How fast it goes down now!" said Susie. "I wonder if it will go lower
+than it did out on the porch. It's down to forty-eight."
+
+"Why does Jane set the kettle of cold water on the stove?" asked Uncle
+Robert, pointing to it.
+
+"To boil the water," answered Susie.
+
+"What makes the water boil?"
+
+"Why, the fire, of course."
+
+"How long will the stove stay hot?"
+
+"As long as there is fire in it."
+
+"Longer than that," said Donald. "It doesn't grow cold the minute the
+fire is out."
+
+"What becomes of all the heat?" asked Uncle Robert.
+
+"Oh, it goes all round the room."
+
+"Let's put the thermometer in the hot water," said Susie.
+
+"Oh, see it go up!" said Donald. "It is one hundred and fifteen
+already."
+
+"What is the difference in degrees between the cold and the hot water?"
+asked Uncle Robert.
+
+"Sixty-seven degrees," said Frank.
+
+"What makes the difference in degrees?"
+
+"The difference in the heat," said Frank.
+
+"If the water was boiling and the thermometer large enough," said Uncle
+Robert, "it would go to two hundred and twelve."
+
+"That would be ninety-seven degrees higher," said Frank.
+
+"Wouldn't that be a big thermometer!" exclaimed Susie.
+
+"Now put the thermometer on the floor," said Uncle Robert.
+
+"It's seventy-two degrees now," said Donald in a few minutes.
+
+"Let's put it on the broom," said Susie, "and hold it up to the
+ceiling."
+
+"It's warmer up there," said Frank, looking at the little gray cylinder
+when they brought it down. "It is six degrees higher than it was on the
+floor."
+
+"Why?" asked Uncle Robert.
+
+"The heat must go up there," said Donald.
+
+"It goes into the next room when the door is open," said Frank.
+
+"Does it go outdoors?" asked Uncle Robert.
+
+"Let's open the window and see," said Susie.
+
+Frank opened the window, but, instead of feeling the warm air going out,
+he felt the cool air coming in.
+
+"Uncle," asked Donald, "isn't the room full of air already?"
+
+"Yes," answered Uncle Robert.
+
+"Then I don't see how any more can come in at the window."
+
+"Are you sure none goes out?"
+
+"I could feel it coming in," said Frank.
+
+"Jane," asked Uncle Robert, "have you a candle?"
+
+"Here is one, sir," said Jane, taking a candlestick from beside the
+clock on the shelf.
+
+Uncle Robert lighted it and held it near the window, just below the
+sill. The flame flickered as the air from the window struck it, and then
+turned straight into the room. He raised it just above the opening.
+Instantly the flame pointed toward the window, but it did not flicker as
+it had when held below the sill.
+
+"The air must be going out up there," said Frank, "but it doesn't blow
+so strongly as the air coming in."
+
+"The air that comes in is cooler than the air that goes out," said
+Donald.
+
+"What makes the water boil?" asked Uncle Robert, turning to the kettle
+on the stove, which had now begun to sing.
+
+"Why, the heat, of course," said Donald.
+
+"What raises the lid?" asked Uncle Robert.
+
+"The kettle is too full," said Frank. "It is going to boil over."
+
+"Why didn't the water run over when it was cold?" asked Uncle Robert.
+"The kettle didn't seem full then."
+
+"Somehow it seems to get more than full when it boils," said Donald.
+"See, it is boiling over."
+
+Just then Jane took a pan of apples out of the oven. Each one looked
+like a small volcano.
+
+"What happens to the apples when they bake?" asked Uncle Robert.
+
+"They just swell up so big their jackets won't hold them," said Donald,
+laughing.
+
+"It is heat that makes the bread rise, isn't it?" asked Frank.
+
+"Of course," said Susie. "Don't you know sometimes if the bread doesn't
+rise, mother says it is because it is too cold?"
+
+"There is something besides heat that makes the bread rise," said Uncle
+Robert.
+
+"Yes," replied Susie, "the yeast; but it must be warm--I know it must."
+
+"It seems as though everything is bigger when it is hot than when it is
+cold," said Frank. "And now I believe I understand something that
+happened not long ago."
+
+"What was it?" asked Uncle Robert.
+
+"Peter and I were driving to town," began Frank, "and the tire of one of
+the wagon wheels slipped right off. We managed to get to the
+blacksmith's shop, and he put the tire in the fire until it was hot. Then
+he put it on the wheel, but it was still loose. We couldn't have gone a
+step without its coming off again. He brought cold water and poured over
+it, and soon it was as tight as could be. I thought the water made the
+wood of the wheel swell up--you know water does that to the pails and
+tubs when they leak; but now I believe the fire made the tire larger, and
+then the cold water made it small again. That is just what happened."
+
+[Illustration: The blacksmith shop.]
+
+"But air can't grow bigger, can it?" asked Donald.
+
+"If you can find an empty bottle, Donald," said Uncle Robert, "perhaps
+we can soon find out about it."
+
+Uncle Robert took a piece of thin rubber out of his pocket and tied it
+tightly over the mouth of the bottle."
+
+"By the way," he said, "is there anything in this bottle?
+
+"No," said Susie, looking through the glass.
+
+"Oh, yes," said Donald, "there is air in it."
+
+"Well," replied Uncle Robert, "please get a pan of hot water, Frank."
+
+Frank brought the water, and as Uncle Robert began to put the bottle
+into it they all exclaimed:
+
+"Be careful; you'll break the bottle!"
+
+"What will make it break?" asked Uncle Robert, pausing.
+
+"Why, the hot water," said Susie.
+
+"It always breaks glass if you put it in too quickly," said Donald.
+
+[Illustration]
+
+"Well, we'll warm it a little first," holding the
+bottle close to the water. "I think I can try it now."
+
+As he spoke he lowered the bottle into the water, and the rubber tied
+over the neck began to bulge out.
+
+"See!" cried Susie. "What makes it do that?"
+
+"Try the cold now," said Uncle Robert. "Here, Donald, hold the bottle in
+this pail of cold water."
+
+"The rubber is going down," said Donald in a moment. "It is going right
+into the bottle."
+
+"Does the air in the bottle pull the rubber in with it?" asked Susie.
+
+"But, Uncle Robert," said Donald, "what if wagon tires, apples, and air
+do swell up when they are hot? I don't see what all that has to do with
+the thermometer."
+
+"I think I see," said Frank. "Why wouldn't this gray stuff in the
+thermometer get bigger when it's hot, if everything else does?"
+
+"What is it that moves up and down in the thermometer?" asked Susie.
+
+"It is mercury," answered Uncle Robert, "which is sometimes called
+quicksilver."
+
+"It looks like silver," said Susie, examining it closely.
+
+"Perhaps you can see this better," said Uncle Robert, taking a small
+bottle of mercury from his pocket and pouring a little into Donald's
+hand.
+
+"How heavy it is!" exclaimed he, letting it roll about. "It feels just
+like lead."
+
+"It is almost twice as heavy as lead," replied Uncle Robert.
+
+"Put it in my hand, Donald," said Susie. "There, you've spilled it on
+the floor! Just see it run around!"
+
+"Is it always soft like this?" asked Frank.
+
+"No, it becomes hard when it is very, very cold."
+
+"How cold, uncle?" asked Donald, looking at the thermometer.
+
+"Thirty-nine or forty degrees below zero," was the reply. "In the
+coldest of countries alcohol thermometers are used. It must be much
+colder than that to freeze alcohol."
+
+"Why is mercury used, uncle?" asked Frank.
+
+"Because it takes a very great heat to make it boil." said Uncle Robert.
+"Then you have seen how quickly it shows a change of temperature. When
+it is warm we call it a high temperature, and when it is cold it is
+called a low temperature."
+
+"That is because the mercury goes up when it is hot, and down when it is
+cold, isn't it?" said Donald. "I wonder how it would feel if it was
+forty degrees below zero. See, it is away down to there!"
+
+"Do you remember that day last winter when Peter froze his ears driving
+to town?" asked Frank. "Well, it was twenty below that day at the post
+office. I saw it. But father is calling me; I must go."
+
+
+
+
+CHAPTER IV.
+
+WITH THE ANIMALS.
+
+
+"Don't forget to set that hen, Donald," called Mr. Leonard, as he and
+Frank went away together. "I think there are enough of those Plymouth
+Rock eggs for one more setting."
+
+"You ought to see our little chickens, Uncle Robert," said Susie. "They
+are just too cunning for anything."
+
+"When you go to set the hen, Donald," said Uncle Robert, "I will go with
+you. Then you can show me everything about the barn."
+
+Donald went to the storeroom and soon came back with the eggs.
+
+"There are thirteen," he said, as he joined Uncle Robert in the porch,
+"but I think she can take care of them. She's one of the largest hens
+we have."
+
+Then together they went to the henhouse, which stood next to the barn.
+The chickens, seeing the basket in Donald's hand, ran toward him.
+
+"You needn't think I am going to feed you again so soon," he said. "You
+have had one breakfast this morning."
+
+Donald always talked to all the animals as though they could understand
+him.
+
+[Illustration: The poultry yard.]
+
+The mother hens paid no attention. With quiet dignity they walked about,
+their broods of fluffy little chicks looking like balls of gold in the
+sunshine. With a "Cluck! cluck!" each anxious mother called her children
+to her as her sharp eyes discovered some new dainty. 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 mother.
+
+"How many little chickens are there?" asked Uncle Robert as they stopped
+to watch them.
+
+"There are forty-six hatched," said Donald. "Three hens are setting, and
+this one will make four."
+
+"I see you have some fine turkeys, too," said Uncle Robert.
+
+The big turkey cock spread his tail and strutted about before them as if
+he understood how much he was admired.
+
+"Mother thinks a great deal of her turkeys," said Donald. "They are much
+harder to raise than the chickens. But mother knows just how to do it.
+We don't lose many."
+
+"Have you ducks and geese, too?" asked Uncle Robert.
+
+"Yes," said Donald, "but I don't see any of them about. They must have
+gone to the creek. There they are," and Donald pointed toward the
+pasture where a line of white could be seen moving slowly along under
+the trees.
+
+"They march pretty well, don't they?" said Uncle Robert. "Do they always
+go that way?"
+
+"Not always," said Donald, "but very often. When that old drake wants to
+take a swim, he starts and the rest follow. You'd never catch him
+walking behind."
+
+"As the head of the family I suppose he thinks it is his place to lead,"
+said Uncle Robert, smiling.
+
+Donald laughed. "Wouldn't it he funny," he said, "if father made us
+follow him that way?"
+
+They found the hen to whom they were carrying the eggs on an empty nest.
+Donald drove her off that he might put in the eggs, but she was very
+cross with him for disturbing her. She walked about with her feathers
+ruffled up, clucking angrily, but eagerly went back to her nest as soon
+as they were gone. She moved the eggs about with her feet, placed them
+to suit herself, and contentedly settled down.
+
+Donald then led Uncle Robert into the barn, where old white Nell stood
+in her stall. Besides Nell there were three strong Normandies in other
+stalls, and two stalls that were empty.
+
+Mr. Leonard had a very large barn. There was the main floor, running
+through from the two big rolling doors at either end. The great hay mows
+on both sides, reached by short ladders, held some of last year's
+cutting. Under the mows were the stalls for the horses and the
+stanchions for the cattle. A machine for cutting hay stood on the barn
+floor.
+
+Under the barn was a deep, roomy cellar, in one corner of which was the
+sheep pen, lighted by large windows.
+
+Near the barn was a tool house, in which all the tools and machinery
+were housed during the winter.
+
+"It pays to have a nice warm barn and a good place to keep the tools
+from rusting," said Uncle Robert. "Do you always keep the horses in the
+barn when they are not in use?"
+
+"Oh, no," said Donald. "Sometimes they run in the pasture along the
+creek. The cows and sheep are there now. After the timothy and clover
+are cut we'll put them in those fields."
+
+"Do you keep many cows?"
+
+"We have six cows and two calves," replied Donald. "Father gave one calf
+to Frank and one to me. They're beauties. All our cows are Jerseys.
+Frank and I are going to keep ours until they're grown. 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 it. There's a creamery not far
+from here."
+
+"Does your father sell the milk there now?" asked Uncle Robert.
+
+"Not now," said Donald. "Mother likes to make the butter herself."
+
+"That's why it is so good," said Uncle Robert.
+
+"Has Susie a calf too?"
+
+[Illustration: The Barn.]
+
+Susie, tired of waiting for them to return, had come to see what they
+were doing. So she answered for herself.
+
+"No, uncle," she said, "but I have the prettiest little lambs you ever
+saw. They always run to me when they see me coming. Please come out to
+the lot and see them."
+
+"How many have you?" asked Uncle Robert.
+
+"Two," replied Susie. "They're twins, and are just alike. Their mother
+is dead. It was cold when they were born. There was snow on the ground.
+Father brought them into the kitchen in a basket to keep them warm.
+Mother and I taught them to drink milk, so father gave them to me. I'm
+going to keep them always."
+
+"Father likes us to have our own things to take care of," said Donald.
+"I think it's ever so much more fun, don't you, uncle?"
+
+"Yes, indeed," said Uncle Robert. "But you help take care of all the
+animals, don't you?"
+
+"Oh, yes," replied Donald, "and I like them all; but my calf seems just
+a little nicer than the rest. I know it isn't any better, really, but I
+like to think it is my very own."
+
+They stopped to watch the pigeons circling about the pigeon house.
+
+"I love to watch the pigeons," said Susie. "See all the pretty colors in
+their feathers!"
+
+[Illustration]
+
+"Are they very wild?" asked Uncle Robert.
+
+"Oh, no," said Susie, "they're very tame. When we throw grain to them
+they come down all around us."
+
+"Come and see my pigs!" shouted Donald, who had run ahead and was
+looking into the pen.
+
+Four white, fat Berkshire pigs lay in the straw, lazily rolling their
+little eyes toward their friend and feeder. A succession of grunts
+served for conversation.
+
+"I put in fresh straw every day," said Donald, "so my pigs can keep
+themselves clean. And they have a patent trough to eat out of."
+
+"I thought farmers in the West let their pigs run in the woods," said
+Uncle Robert.
+
+"We had a lot of razorbacks for a while, but they didn't pay," said
+Donald. "Our Berkshires make nice pork."
+
+"How warm the sun is getting!" said Uncle Robert as they turned away
+from the pigpen.
+
+"The wind is from the southwest," said Donald, looking at the weather
+vane on top of the barn. "It always gets warmer when the wind is from
+that direction."
+
+"Uncle," said Susie, "before we begin to plant the seeds let's go and
+see my lambs."
+
+"You go ahead, and I'll get some salt for the sheep," said Donald. "They
+always run to me when they see me coming with a pan. They know what that
+means."
+
+Donald soon joined them with the pan of salt.
+
+"Mother says she can't work in the garden until afternoon," he said, "so
+we needn't hurry back."
+
+As they entered the pasture the sheep were quietly grazing on the slope
+of the hill, where the grass was nibbled very short. A few lambs were
+frisking together at the foot of the hill.
+
+"See the lambs playing, uncle," said Susie. "The two little ones with
+long tails and black noses are mine. Aren't they cunning? They'll see me
+in a minute. Then how they will run!"
+
+The quick ears of the sheep caught the sound of their voices. They
+raised their heads. Donald held out the pan of salt, shaking it gently.
+In a moment one of the flock started slowly toward them. Donald stopped
+under one of the large oak trees that grew on the top of the hill. Uncle
+Robert and Susie stood beside him. The old sheep came nearer. One by one
+the rest of the flock began to follow. The lambs stopped playing. Susie
+held out her hand and called softly, "Come, Sally! Come, Billy!"
+
+[Illustration: Feeding the sheep.]
+
+The two little lambs switched their tails and started up the hill.
+Donald sprinkled a little of the salt on the ground. Then the whole
+flock broke into a run, and the sheep were soon eagerly licking up the
+salt as Donald scattered it about for them.
+
+Susie's lambs came straight to her side and began to lick her hands and
+sniff about her dress.
+
+"They think I have something for them," she said. "Let me have some
+salt, please, Donald."
+
+Filling each of her hands with salt, she held them out, and the lambs
+eagerly licked it from the little round palms.
+
+"The cows are down by the creek, uncle," said Donald. "Shall we go to
+see them? You must see my calf."
+
+"Come on," cried Susie, and began to run as fast as she could go.
+
+The little lambs, always ready for a play, skipped about her. How
+merrily Susie did laugh as they ran ahead and then turned around with
+their noses to the ground and their tails in the air, waiting for her to
+come and catch them!
+
+"They always want me to play with them," she said, quite out of breath,
+when Uncle Robert and Donald caught up.
+
+"What beautiful cows!" exclaimed Uncle Robert as the little Jerseys
+lifted their shy faces from the grass to look at them. "I never saw
+finer ones."
+
+"That is my calf," said Donald, pointing it out with much pride, "and
+that one over there is Frank's. The only way we can tell them apart is
+that Frank's has more black on its face than mine has."
+
+[Illustration: Donald's calf.]
+
+"Toot-toot-t-o-o-t!" The sound came from the house.
+
+"There's the horn!" exclaimed Susie. "It must be dinner time."
+
+"So soon?" said Uncle Robert. "How quickly the morning has gone!"
+
+"I tell you I'm hungry," said Donald. "I didn't think of it before, but
+I'm almost starving."
+
+
+
+
+CHAPTER V.
+
+IN THE FLOWER GARDEN.
+
+
+In the afternoon they all went into the garden. Donald and Mrs. Leonard
+began at once to set out the tomato plants that had been started in a
+box. Susie and Uncle Robert walked about, planning where the flower
+seeds should be planted.
+
+"The verbenas are in this bed," said Susie. "I had them last year. I
+wish they would begin to come up. Don't you think, uncle, it will be
+nice to have the mignonette in with them?"
+
+"Yes," replied Uncle Robert, "but where are your nasturtiums?"
+
+"I haven't any nasturtiums," said Susie. "I wish I had. Jennie Wilson's
+mother had them last year. They bloomed all summer."
+
+"We can send for some seeds and get them in time to plant," said Uncle
+Robert.
+
+"Oh, thank you, uncle," exclaimed Susie. "How nice! I'll save this big
+bed for nasturtiums, and the bachelor's buttons can go over there."
+
+[Illustration: Poppies]
+
+"The nasturtiums would do better by the fence and the porch," said Uncle
+Robert. "They like to climb."
+
+"All right," said Susie; "then we can have this bed for something else."
+
+"Have you any poppies?" asked Uncle Robert, smiling. "Poppies are my
+favorite flowers."
+
+"Are they, uncle? Then we'll have poppies in this bed."
+
+"Thank you, dear," replied Uncle Robert, taking out his notebook. "We'll
+send for the poppy seeds, too."
+
+"I think that finishes the beds," said Susie. "Let me see," and, walking
+down the path, she pointed out where each kind of flower was to grow.
+
+"You might draw it now," said Uncle Robert; "then we'll make no
+mistake."
+
+"Oh, goody!" cried Susie. "That's what I'll do. Wait until I get a
+pencil and paper."
+
+"Here is a pencil," said Uncle Robert, taking one from his pocket, "and
+perhaps this old envelope will do to draw it on."
+
+But Susie thought not. "It's too small," she said. "I'll get a nice
+piece of paper in a minute."
+
+Away she ran to the house, and soon came back with a large sheet of
+fresh white letter paper in one hand and Frank's geography in the other.
+
+"I'm going to draw my garden," she called to Donald and her mother,
+holding up the paper for them to see.
+
+"I'll make the paths first," she said, laying the paper on the
+geography, and taking the pencil from Uncle Robert. "Then I can put in
+the beds afterward."
+
+When the paths were drawn, Susie named the beds and marked them off on
+the paper.
+
+"Please write the names for me, Uncle Robert," she said. "I can't spell
+all the big words."
+
+"I will write them on this paper," said Uncle Robert, "and when you see
+how they look you can write them on your plan."
+
+"Oh, yes," said Susie, "that will be the nicest way."
+
+"See, mother," cried Susie, running to her, "this is my garden. Now I
+know just what is to be in every bed."
+
+[Illustration: Susie's garden.]
+
+"Where are you going to get poppies?" asked Donald, looking at the plan
+on the paper.
+
+"Uncle Robert is going to send for the seed," answered Susie. "He likes
+poppies best of all the flowers. We are going to have nasturtiums, too.
+They are to grow by the porch and the fence."
+
+"That will be fine, dear," said Mrs. Leonard. "What a beautiful garden
+we shall have!"
+
+"I can hardly wait," cried Susie, dancing along the walk. "Come, uncle,
+let's plant what seeds we have now."
+
+"Do we need to do anything to the ground," asked Uncle Robert, "before
+the seeds are put in?"
+
+"Only rake over the top a little," said Susie, taking up her rake and
+going to work. "It has been spaded. See how light and fine it is
+underneath! Ugh! I wish the old worms would keep out!"
+
+"Don't be too hard on the worms," said Uncle Robert. "They are your best
+helpers."
+
+"I don't see how that is, uncle," said Susie, looking up in surprise.
+
+"You just said the soil was light and fine," said Uncle Robert. "Don't
+you know you have to thank the worms for keeping it so?"
+
+"Are you sure, uncle?" asked Susie. "I thought the worms ate the
+plants."
+
+"The earthworms never eat the plants," said Uncle Robert. "They eat the
+soil, and so keep it worked over. It is the cutworm that eats the
+plants."
+
+Just then Donald came over from the vegetable garden.
+
+"Why, you've only just begun," he said. "We're all through. Don't those
+tomato plants look nice?"
+
+"Well," said Susie, "you didn't draw your garden. That took a long time,
+didn't it, uncle? You rake those beds for me, Don, while I put the seeds
+in."
+
+"I'd just as soon," said Donald, taking the rake. "What goes here?"
+
+"Mignonette," said Susie. "When any one wants to know about my garden
+now, they can look at the drawing."
+
+Uncle Robert smiled.
+
+"What makes you think you'll have mignonette there?" he asked, as Susie
+marked a little furrow with a stick in the soft, warm soil.
+
+"Why, these are mignonette seeds," she replied. "I gathered them myself.
+Don't you think they'll grow, uncle?"
+
+"Certainly I do," replied Uncle Robert.
+
+"It would be a pretty dead seed," said Donald, "that wouldn't grow in
+this soil."
+
+"Are seeds alive?" asked Uncle Robert, smiling.
+
+"Why, I--I don't know," said Donald, looking puzzled. "I never thought
+about it. I just said that. They don't look like it, that's a fact, but
+they surely wouldn't grow if they were dead, would they?"
+
+"Do all seeds grow in the same way?" asked Uncle Robert.
+
+"I never thought about it," said Donald.
+
+"Neither did I," said Susie. "I just know if I plant mignonette,
+mignonette will grow; and if I plant sweet peas, sweet peas will grow.
+That's all I ever thought about it."
+
+"Would you like to know?" asked Uncle Robert.
+
+"Oh, yes," said Susie.
+
+"How can we?" asked Donald. "The seeds are in the ground, and we can't
+see them."
+
+"If Susie is willing to dig up one of her sweet peas," said Uncle
+Robert, "perhaps it will tell us what it has been doing since she
+planted it last week."
+
+"Oh, yes," said Susie. "See if you can find one, Don. I put lots in."
+
+Down on their knees went Susie and Donald, and began digging in the
+soil.
+
+"Here is one," said Donald, "just ready to come up, and another close to
+it. The tip of it must have been through. See, it is green."
+
+"Wouldn't it be green in the ground?" asked Susie, looking closely at
+the tiny plant.
+
+"Why, no," said Donald. "Things are never green when they're covered up.
+It's light that makes things green. Don't you know how yellow the grass
+gets if a board lies on it, and what yellow stalks the potatoes have
+when they sprout in the cellar? It must be the light that makes them
+green."
+
+"Oh, yes," said Susie. "But see how big that pea is! It's about twice as
+big as it was when I planted it."
+
+[Illustration: Sprouting pea.]
+
+"See," said Donald, "the roots grow from the same place that the stem
+does. I should think it would be better if one came from one side of the
+pea, and one from the other."
+
+"What becomes of the rest of the seed?" asked Uncle Robert.
+
+"I don't know," said Susie. "Is it of any use?"
+
+"It is of the greatest use," replied Uncle Robert. "The little pea plant
+couldn't live without it. It is its food that the mother sweet pea
+gathered last summer from the soil and air, and stored away in the
+little round ball for her baby to feed on until it should be big enough
+to get its own food."
+
+"Do you really mean, uncle," cried Susie, with shining eyes, "that the
+sweet peas I have planted in that bed are the children of those I had
+last year?"
+
+"Why not?" asked Uncle Robert, with a smile.
+
+"I never thought of it before," said Susie, looking at the tiny plant in
+her hand; "but I like it. It seems just like a family."
+
+"And that's what it is," said Uncle Robert.
+
+"Don't you think this baby had better go back to bed?" said Susie,
+making a deep hole in the ground.
+
+"Wait a moment, Susie," said Uncle Robert.
+
+"Suppose we take it for a visit to the beans, and see if they grow like
+it."
+
+So they went to the vegetable garden, where they found a great many
+plants, each with two strong, thick leaves sticking through the soil.
+Some were quite green and showed a tiny shoot between them. Others were
+yellow, with only the tips turned green.
+
+"Dig one up, Don," said Susie, "and let's see if it is like the baby
+pea."
+
+Donald pulled one up, but no bean was to be seen. The stem grew straight
+into the ground, ending with a little bunch of roots.
+
+"Where's the bean?" asked Susie.
+
+"These two leaves must be the bean," said Donald. "Don't they look like
+it?" He took a bean from his pocket and held it close to the little
+plant.
+
+"Well, I never!" cried Susie. "If those two leaves aren't just the bean
+split open! Are they any good that way, uncle?"
+
+"Yes, indeed," said Uncle Robert, smiling.
+
+"They feed the little bean just as the pea does. But they do even more.
+What do you think they will do when the sun goes down and the air gets
+cool?"
+
+[Illustration: Sprouting bean.]
+
+"Oh, I know." said Donald. "I've seen them lots of times. They just shut
+together tight." "And that keeps the little bud you see in there as warm
+as you are in your bed."
+
+"Isn't that wonderful?" said Susie. "Why, uncle, it's just as if they
+could think!"
+
+"The leaves drop off after a while," said Donald. "I often see them
+lying on the ground."
+
+"Yes," said Uncle Robert. "When the plant is strong enough to take care
+of itself, their work is done."
+
+"Are there any other plants that make leaves out of the seeds, uncle?"
+asked Donald.
+
+"Oh? yes," replied Uncle Robert. "Squashes and pumpkins do, and many
+others. Some have more perfect leaves than these. Let us look at the
+morning glories by the porch."
+
+[Illustration: Morning glory.]
+
+"They come up every year by themselves," said Susie.
+
+She ran to her garden, saying, "I'm going to put this pea-baby to bed
+again. Do you think it will grow, uncle?"
+
+"It may, but it is not good for it to be out of bed too long."
+
+"I'll put a stick by it," said Susie, "so I can watch it. Good-by,
+baby," giving the ground a little pat; "go to sleep."
+
+Then she ran after Uncle Robert and Donald.
+
+"How thick the morning glories are!" said Donald. "Some of them have
+several leaves on, but here is one with only two."
+
+"They don't look as the bean leaves do," said Susie. "The beans are so
+thick! These have real leaves."
+
+"Yes," said Uncle Robert, "and if you could see them in the seed, you
+would see these leaves all curled up in their hard coat."
+
+"This one is just putting its head through the ground," said Susie, "and
+it has part of the shell on it yet."
+
+"It looks as the little chickens do sometimes," laughed Donald, "when
+they come out of the nest with a piece of the shell sticking to their
+backs."
+
+"That hard shell is a great protection to the tender plant as it works
+its way up through the soil," said Uncle Robert.
+
+"If these seed leaves are real leaves, uncle," asked Donald, "what feeds
+the baby morning glories?"
+
+"There is plenty of food in the seed around the leaves," said Uncle
+Robert. "When the seed gets moist in the ground, it becomes so soft that
+the plant can use it. Have you ever noticed when you were eating corn
+the little hard bud that grows in each grain close to the cob?"
+
+"Yes, uncle," answered Susie. "That is the sweetest part of the corn."
+
+"That is the part," said Uncle Robert, "from which the new plant grows,
+and all the rest of the grain is the food stored up for it."
+
+"I wish we had some corn," said Susie, "so we could see it."
+
+"I'll go and get some," said Donald.
+
+"Oh, do, Don," said Susie, "and while he's gone, Uncle Robert, I can
+plant the rest of my seeds. I have only a few left."
+
+So Donald ran to the cornfield and Susie went to the garden. When he
+came back she had finished, and they joined Uncle Robert on the piazza.
+
+"The corn grows out of the side of the seed," said Donald. "See what a
+big root it has for such a little plant!"
+
+[Illustration: Sprouting corn.]
+
+"How pretty those leaves are!" said Susie. "They look like two little
+green feathers." "Some one else had the same thought, Susie," said Uncle
+Robert. "Did you ever hear the story the poet Longfellow tells about how
+the corn came to the Indians? You know it is called 'Indian corn.'"
+
+"No, uncle," said Susie. "Do tell us."
+
+So as they sat beside him on the piazza. Uncle Robert told the story of
+Hiawatha and Mondamin.
+
+"Hiawatha was a brave young Indian chief," began Uncle Robert, "who
+wanted to help his people. He knew that there were times when they had
+no food. In the winter the birds flew away. The 'big sea water,' as they
+called the great lake, was frozen over, and they could catch no fish.
+There were no wild berries in the woods.
+
+"'Master of Life,' he cried,'must our lives depend on these things?'
+
+"He was very unhappy. He could not eat. He lay in his wigwam, fasting
+and praying for some good to come to his people.
+
+"One evening as he lay watching the setting sun he saw a youth coming
+toward him. His dress was green and yellow, and over his yellow hair he
+wore a bright green plume.
+
+"'The Master of Life has sent me,' said the youth. 'I am Mondamin. It is
+only by hard labor Hiawatha, that you can gain the answer to your
+prayer. Rise now, and wrestle with me.'
+
+"Hiawatha was weak from fasting, but he did as Mondamin commanded. Until
+the sun had set they wrestled together. Then Mondamin went away as
+silently as he had come.
+
+"A second time he came, and a third. Then he said: "'You have fought
+bravely, Hiawatha. I shall come once more. You will conquer me. Then you
+must take off my dress of green and yellow and my nodding plumes. Make a
+bed in the soft warm earth for me to lie in. Let nothing come to disturb
+me as I slumber. Only let the sunshine and the rain fall upon me. You
+must watch beside me, Hiawatha, until my sleep is over.'
+
+"Then he was gone.
+
+"When they wrestled the next night it was as Mondamin had said. He was
+conquered. Then, day after day, Hiawatha came and watched,
+
+ "'Till at length a small green feather
+ From the earth shot slowly upward.'"
+
+"There it is," whispered Susie.
+
+"Sh!" said Donald.
+
+"Then another and another," continued Uncle Robert, "and before long the
+corn was waving its long, green foliage in the sunshine.
+
+"'It is Mondamin!' cried Hiawatha,'the friend of man, Mondamin!'"
+
+"What a lovely story!" cried Susie as Uncle Robert finished. "I wish
+Frank could have heard it."
+
+"We'll find it in your mother's book of Longfellow's poems and let Frank
+read it," said Uncle Robert.
+
+"Let's tell him about the seeds first," said Donald. "He'll like it
+better then."
+
+[Illustration: A stalk of corn.]
+
+
+
+
+CHAPTER VI.
+
+SUNLIGHT AND SHADOW.
+
+
+It was a busy time on the farm. 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 much.
+
+"It's wonderful," said Mr. Leonard one evening, looking up from his
+paper, "how fast the corn is growing. Even the late planting is coming
+on."
+
+"That's because the weather is so warm," said Donald.
+
+"I wonder what makes it warm?" said Uncle Robert.
+
+"Why, Uncle Robert," exclaimed Susie, "it's spring! That's what makes it
+warm."
+
+"But what makes it spring, little girl?" asked Uncle Robert.
+
+"Why, it is always spring in May," said Susie.
+
+"I know of a country where it is spring in September," replied Uncle
+Robert.
+
+"How can it be?" asked Susie. "I thought springtime always came in May."
+
+"What makes us know that it is spring?" asked Uncle Robert.
+
+"Oh, it gets warmer all the time. The birds come, things begin to grow,
+and the flowers bloom."
+
+"But what makes all this happen just now?"
+
+"It's the sun," answered Donald from the floor, where he was playing
+with his great St. Bernard dog, Barri. "You know it rises earlier and
+sets later every day now than it did a while ago. It's hotter too."
+
+"It goes higher at noon," said Frank. "In the middle of summer it is
+almost straight over our heads, and in the winter it seems ever so much
+farther to the south. I've often noticed that."
+
+"So have I," said Donald. "And in the winter the shadows are longer than
+they are in summer. It must be because the sun isn't so high up."
+
+"Aren't shadows funny?" said Susie. "One day when I was coming in to
+dinner, just for fun I tried to walk on my shadow, and I could step on
+my head."
+
+"I've done that lots of times," said Donald. "But it's a strange thing.
+Sometimes I can step clear over my head--I mean in the shadow--and then
+again I have to step on it."
+
+"And when you jump," said Susie, "it spoils it. The shadow always jumps
+too."
+
+"What kind of weather was it when you had to jump to it?" asked Uncle
+Robert.
+
+"I don't remember," said Donald. "Would the weather make any
+difference?"
+
+"I remember," said Susie, "because one time when I was jumping that way
+I fell down and was almost buried in the snow.
+
+"Then it was winter, wasn't it?" asked Uncle Robert.
+
+"It must have been," said Frank.
+
+[Illustration: Shadow stick.]
+
+"And since you told us that the shadows at noon tell why it is warmer in
+summer than in winter I've been watching them. They get shorter all the
+time." "How would you like to measure the shadows every day," said Uncle
+Robert, "and see if you can find out when they are shortest and when
+they are longest?"
+
+"How can we?" asked Susie. "Shadows are so queer."
+
+"Yes," said Uncle Robert, "shadows are queer, but, if we take one that
+doesn't jump as yours does, don't you think we can measure it?"
+
+"Of course we can," said Frank. "We can use the house. That always
+stands still."
+
+"The house might do," said Uncle Robert; "but wouldn't it be better to
+have a shadow stick?"
+
+"Where can we get one?" asked Donald.
+
+"What is it made of?" asked Frank.
+
+"It is like this," said Uncle Robert, taking paper and pencil from his
+pocket. "There is one long piece of board, and one short one nailed to
+the end--so," drawing it on the paper.
+
+"Oh, that's easy enough made," said Donald. "We can do it ourselves
+right here in the tool house."
+
+"Let's make it to-morrow, Don," said Frank.
+
+"It must be set up some place with the upright end turned toward the
+south, so that just at noon the shadow of the short piece may fall
+straight on the board. By drawing a line across the board at the top of
+the shadow and marking the date on it, we can tell how the length of the
+shadow changes."
+
+"Uncle," asked Donald, "when it is winter here, is it summer in some
+other part of the world?"
+
+"Yes," was the reply, "and now that our summer is coming, the people
+there are beginning to have winter."
+
+"Then," said Frank, "when it gets cooler here in the fall it is growing
+warmer there, and that would make their spring come in September,
+wouldn't it? Do you see, Susie?"
+
+[Illustration: Eskimo scene.]
+
+"Yes," answered Susie, "but it seems all mixed up. I thought it was the
+same as it is here all over the world."
+
+"Oh, I didn't," said Donald. "I've read about countries where it is
+summer all the time, and is so hot that the people don't do anything but
+lie under the trees and sleep. And there are other countries where it is
+winter all the time, and the people dress in furs and make their houses
+of snow and ice. I read all about it in a book once, but it didn't tell
+why it was so. I knew, of course, the sun had something to do with it."
+
+"Why, you know, Don," said Frank, "we learned all that in our geography
+at school."
+
+"Yes," said Donald, "but I never thought about that in the geography as
+meaning any real country."
+
+"What did you think it meant?" asked Uncle Robert.
+
+"Oh," said Donald, "just a lesson in the book."
+
+"Well," said Frank, "I always thought it was some country, but I never
+knew where. I didn't think much about it after I said the lesson."
+
+"I should think not," said Uncle Robert, not sorry that the teacher had
+gone away and the school had been closed.
+
+"I wish when books tell things they'd tell why they're so," said Frank.
+
+"Perhaps if we think about these things," said Uncle Robert, "we may be
+able to answer some of the 'whys' for ourselves."
+
+"We can tell by the thermometer just how warm it is every day," said
+Susie, "but it won't tell us why."
+
+"The shadow stick may help us there," said Uncle Robert.
+
+"I am afraid I shall forget," said Donald.
+
+"I have some little notebooks in my trunk," said Uncle Robert. "Suppose
+I give you each one and let you write down what the thermometer and the
+shadow stick say every day."
+
+"What fun that'll be!" cried Susie. "When may we begin?"
+
+"To-morrow morning, if you like," replied her uncle. "I will get the
+books for you now."
+
+He went away to his room, and soon returned with the notebooks.
+
+"I'll tell you, uncle," said Frank as he thanked Uncle Robert for his
+book, "how would it do for each of us to look at the thermometer at a
+different time of the day?"
+
+"The very thing!" replied Uncle Robert, well pleased. "You are always up
+early, Frank, so suppose you look at six in the morning, Susie at twelve
+o'clock, and Donald at six in the evening. How will that do? Then we
+shall have the record for the whole day."
+
+"I think it will be such fun!" said Susie. "I wonder if our books will
+be very different."
+
+"What makes you think they will be different?" asked Uncle Robert.
+
+"It's always hotter at noon than it is at night or in the morning," said
+Susie.
+
+"Do you know," said Uncle Robert, "there are places all over the United
+States where such records are kept? They are published, and I am to have
+them sent to me every week."
+
+"I wonder if ours will be like them," said Donald, turning over the
+pages of his notebook.
+
+"Even if they should be different." said Uncle Robert, "they may be just
+as true."
+
+"We'll get up early and start the shadow stick the first thing in the
+morning," said Frank, "so as to have it ready by noon."
+
+"How do you know when it is noon?" asked Uncle Robert.
+
+"We look at the clock," said Susie.
+
+"But noon by the clock is not always noon by the sun," replied Uncle
+Robert.
+
+"How can that be?" asked Donald.
+
+"It is noon somewhere on the globe every minute of the twenty-four
+hours," said Uncle Robert. "The sun is always setting and always rising
+somewhere."
+
+The children were puzzled.
+
+"I don't see how that is," said Donald.
+
+"Let us see if we can find out," said Uncle Robert. "Frank, you stand at
+the east end of the room, Donald at the west, and Susie in the middle.
+Now, we'll play that Frank is in New York, Susie here at home in
+Illinois, and Donald in Denver. I'll take the lamp and be the sun. You
+are shadow sticks, you know. Now watch the shadows, and see when they
+point directly north."
+
+Uncle Robert took the lamp and walked slowly from the east side of the
+room.
+
+"My shadow points north," said Frank as Uncle Robert passed him.
+
+"Now mine does," said Susie.
+
+"And mine last of all," said Donald.
+
+Uncle Robert took out his watch. It was ten minutes past eight.
+
+"That is Susie's time," he said. "Would it be the same in New York,
+Frank?"
+
+"I think it would be past that," said Frank, "but I don't know how
+much."
+
+"It is ten minutes past nine by the watch in New York," said Uncle
+Robert.
+
+"When would it be that time in Denver?" asked Donald.
+
+"In an hour by the watch," said Uncle Robert, "but it would not be the
+same by the sun."
+
+"Then the watches don't tell the true time, do they?" said Frank.
+
+"The sun's shadows give us the true time," said Uncle Robert. "We will
+study the shadows, and by and by may learn how the watches and clocks
+are regulated. But how do you think people told the time before they had
+clocks?"
+
+"It must have been by the sun," replied Frank.
+
+"I can tell by the sun when it is noon," said Donald, "but I don't see
+how any one can tell any other hour that way."
+
+"How do you know when it is noon?"
+
+"Why, the sun is highest at noon." said Donald. "and the shadows point
+straight toward the north."
+
+"Early in the morning they point to the west," said Frank, "and in the
+evening they point to the east."
+
+"The people who lived in the world many hundred years ago observed the
+same thing," said Uncle Robert. "There was nothing so strange to them as
+the rising and setting of the sun. They loved the light that came with
+it. They feared the darkness that followed its going away. They told
+many interesting stories to explain this continued appearance and
+disappearance. Some thought the sun was a king riding through the sky in
+a golden chariot. Others looked upon it as a god and worshiped it.
+
+"They soon learned that when it went away it was sure to come again, and
+as they saw how regularly it moved, they felt there must be some power
+back of it to guide it. Through this they were led to a belief in a Being
+that controlled all things.
+
+"They watched the shadows, too, and saw them change just as you see them
+every day. They learned that the shadow is shortest when the day is half
+gone, and they called that time midday. So, by studying the length and
+direction of the shadows, they soon became able to judge the time of
+day.
+
+"Then some one thought to set up a rod and mark the places where the
+shadow fell at sunrise, at sunset, and at midday. The space in between
+was divided for the hours. This was called a sun dial and was the first
+instrument ever made for telling time."
+
+"When was the first one made?" asked Frank.
+
+"That is not known," replied Uncle Robert, "but we read in the Bible of
+the sun dial of King Ahaz, who lived about eight hundred years before
+the time of Christ. That is the first record we have of one."
+
+"How was it made?" asked Donald.
+
+"I do not know how the one King Ahaz used was made," said Uncle Robert,
+"but I can show you how one looked that I saw in an old garden in
+England. This," drawing a half circle, "is the dial on which
+the hours were marked. Around this dial there was a border, much
+cracked, and crumbling away, but I could read the words, 'The sun guides
+me, the shadow you.' The rod, or gnomon, as it is sometimes called,
+stood just halfway between the ends. Where would the noon shadow fall,
+Susie?"
+
+[Illustration]
+
+"In the middle, wouldn't it?" answered Susie.
+
+"And the morning shadow would fall on the west and the evening shadow on
+the east side," said Frank.
+
+"Now we'll put in the shadow stick," said Uncle Robert, drawing a
+triangle on the paper.
+
+"Why don't you make it stand up straight?" asked Donald.
+
+"The shadow does not tell the truth," said Uncle Robert, "unless it
+points in the same way that the north pole does, and that, we know,
+points to the north star. I will explain this some other time."
+
+"Couldn't we make a sun dial?" asked Donald. "I don't believe it would
+be very hard."
+
+"You could make one easily," answered Uncle Robert.
+
+"But let's have the shadow stick first," said Frank.
+
+Susie went to the window and looked out at the clear star-lighted sky.
+
+"Uncle," she said, "the stars all look alike to me, only some are little
+and some are big. How can people know them by their names?"
+
+"Just as anything else is known, dear," replied Uncle Robert, "by close
+and careful study."
+
+"I wish we could study the stars," said Frank.
+
+"We will some time," replied Uncle Robert. "Come out on the piazza now,
+and I will show you the north star. That will be a good beginning."
+
+
+
+
+CHAPTER VII.
+
+THE BAROMETER.
+
+
+One day when it was Donald's turn to go for the mail he found among
+Uncle Robert's letters a small paper. On the wrapper he read "United
+States Weather Report."
+
+It had come. There was already quite a line of figures in each of their
+notebooks. Now they could see what this other record was like. As he
+left the post office he stopped to look at the old thermometer beside
+the door. Then he mounted Nell and rode down the village street and out
+into the pleasant country road.
+
+Uncle Robert was waiting for him on the porch, and as Donald rode away
+to the barn, after giving him the mail, he heard him say:
+
+"Here, Frank, is the Weather Report. Open it and look at it while I read
+my letters."
+
+Donald took off the saddle and gave the horse her supper. Then he
+hurried back to see what Frank had found on the inside of the
+important-looking wrapper. It proved to be a map with queer, crooked
+lines all over it, but it did not look at all interesting.
+
+"Here it says temperature," said Frank, pointing to a list of figures in
+the corner. "Perhaps this is what we want."
+
+"I don't see any numbers there like mine," said Donald, taking his
+notebook from his pocket.
+
+"Let me help you," said Uncle Robert, laying aside his letters and
+coming to where they sat on the steps.
+
+They made room for him, and, as he took the map, he explained:
+
+"This, you see, is a map of the United States. These dotted lines tell
+about the temperature. For instance, look at this one which is marked
+fifty degrees. 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 made."
+
+[Illustration: United States weather map.]
+
+"See," said Susie, "how crooked the line is. Why isn't it straight,
+uncle?"
+
+"Because," was the reply, "as I told you, it goes wherever the
+temperature was fifty degrees. You remember, the first day we had our
+thermometer, we found that there are many things which affect the
+temperature. At some places along this line there are prairies, at
+others forests, at others lakes, and here," pointing to the map, "there
+are high mountains. All of these things affect the temperature, and that,
+of course, changes the direction of the line."
+
+"You say Chicago is the nearest station to us, uncle," said Frank,
+looking down the temperature column. "My record for that day is not so
+very different from the one given here for Chicago."
+
+"Which shows that yours is probably as nearly correct as this is," said
+Uncle Robert, with an encouraging smile.
+
+"But I haven't one number in my book like that," said Susie, looking
+disappointed. "I don't see why."
+
+[Illustration: Susie's notebook]
+
+"I do," replied Uncle Robert. "You make your record at noon, and of
+course, it is warmer then. That is what your book says, does it not?"
+
+"Yes," said Susie, "every number in my book is more than that one."
+
+"That is right," was the reply, "for this record was made at eight
+o'clock in the morning, which is nearer Frank's hour than it is yours.
+So we would expect his to be nearer like this than yours, wouldn't we?"
+
+"It isn't like mine either," said Donald.
+
+"We may have one some time that will be more like yours," said Uncle
+Robert, "for these records are made at eight in the evening as well as
+in the morning."
+
+"Uncle," said Frank, looking closely at the map, "here it says 'High,'
+and there it says 'Low.' What does that mean?"
+
+"It means," said Uncle Robert, "that here there is a low barometer, and
+there the barometer is high."
+
+"Barometer," said Donald. "What is a barometer, uncle? Is it like a
+thermometer?"
+
+"Well, not exactly," was the reply. "With the thermometer, you know, we
+tell the temperature of the air, and with the barometer we tell how
+heavy it is."
+
+"How heavy the air is!" exclaimed Susie. "How funny! Why, uncle, air
+doesn't weigh anything, does it?"
+
+"More than you think, little girl," said Uncle Robert, smiling. "But
+perhaps we can prove whether it does or not. Frank, will you get a pail
+of water? Donald, see if you can find a cork some place; and Susie, run
+in and get a tumbler."
+
+When all was ready Uncle Robert asked Frank to fill the pan with water,
+and Donald to put the cork into it.
+
+[Illustration: Experiment No. 1.]
+
+"There," said Donald, as the cork floated about on the pan of water.
+
+"But I want the cork on the bottom of the pan," said Uncle Robert, "not
+on the top of the water."
+
+"It won't stay there," declared Donald, pushing it into the water again
+and again with his finger. "It is too light. Corks always float."
+
+"How can we make it go to the bottom?"
+
+No one could tell. The children looked puzzled.
+
+"Let us see what this will do," and, taking the glass from Susie's hand,
+Uncle Robert turned it over the cork, pressed it down into the water as
+far as it would go, and held it there. Looking through the glass, they
+could see the cork lying on the bottom of the pan.
+
+"Why, Uncle Robert!" exclaimed Susie, "what--how--"
+
+"It's the glass that does it," declared Donald.
+
+"But the glass doesn't touch the cork," objected his uncle.
+
+"There's air in the glass," said Frank, who had been looking at it
+quietly as the others talked. "That is what presses it down."
+
+"If it's air," said Donald, "why didn't it go down before the glass was
+put over it? There was just as much air about it then, and more, too."
+
+"Let go of the glass, uncle," said Frank, "and see what it will do."
+
+Uncle Robert did so, and the glass instantly turned over, while a big
+bubble of air escaped through the water.
+
+"There," said Frank, smiling, "I told you so!"
+
+"Then air only presses on things when there is something like the glass
+to hold it down. Is that so, uncle?" asked Donald.
+
+"Let us see," was the reply.
+
+[Illustration: Air Pressure. Experiment No. 2.]
+
+Filling the glass with water, he placed a piece of paper over it, and
+quickly turned it upside down. Not a drop of water fell from the glass.
+The paper, now beneath the water, stayed there as though glued.
+
+"Uncle," said Frank, "is it truly the air that holds the paper on and
+keeps the water in the glass? If it presses that way everywhere, why
+don't we feel it?"
+
+"It is because it presses equally in every direction," replied Uncle
+Robert. "Put your hand in this pail of water. Do you feel it pressing on
+your hand?"
+
+"No," said Frank.
+
+"Place it lower in the water. Does it feel any heavier now?"
+
+"Not at all," answered Frank.
+
+"But you know that the water is heavy. Lift the pail, Donald."
+
+"It is heavy," said Donald, setting it down. "I don't see why Frank
+didn't feel a little of the weight of it when his hand was under all the
+water."
+
+"It is this way," explained Uncle Robert. "The water pressed on his hand
+from below as much as from above, and the same on both sides. When you
+lifted it you felt its weight pressing downward only. Now it is just so
+with the air. It presses with such equal pressure that we do not realize
+its weight. It is only when it presses harder from one direction than
+from another that we feel it."
+
+"That's when the wind blows, isn't it, uncle?" asked Donald.
+
+"Yes, my boy," was the reply. "You can see how it is out among the trees
+now."
+
+"But, uncle," said Donald, "how can the air be weighed if it presses the
+same in all directions? It was only when I lifted the whole pail of
+water that I felt how heavy it was. The air can't be weighed if it
+presses up just as much as it does down."
+
+"But if in some way it could be shut off so that it would only press in
+one direction?"
+
+"It might be," answered Donald, "but I don't see how."
+
+Uncle Robert told Susie to put the glass in the water so that it would
+all be below the surface, and, without taking it from the water, to turn
+it upside down. She did so, and then began to lift it slowly out of the
+water.
+
+"See," cried Susie, "the water comes with it. The glass is full. Could I
+lift it clear out that way?"
+
+"Try it," said Uncle Robert, smiling.
+
+But no; when the edge of the glass came out of the water in the pail,
+down went the water with a splash.
+
+"I see how it is," said Frank, who had watched it closely. "There wasn't
+any air in the glass to keep the water out, as there was when we turned
+it over the cork, so the water stayed in it."
+
+"But what made it come up out of the pail?" asked Donald. "There wasn't
+any air under it to press it up."
+
+"Would the air pressing on the water around the glass make it do so,
+uncle?" asked Frank, placing the glass in the water and raising it as
+Susie had done. "It seems as if it might be that."
+
+"That is what it is," replied his uncle. "The air pressing on the water
+in the pail forces it into the glass, where there is nothing to keep it
+from rising."
+
+"If the glass was longer would the water stay in it just the same?"
+asked Donald.
+
+"Yes," was the reply. "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 chance. But come, let us sit down on the steps again,
+and I will tell you about it."
+
+When they were settled he continued:
+
+"Over two hundred and fifty years ago there lived a man named Galileo,
+who learned a great many wonderful things by studying the stars and
+doing just such things as we have been doing. It was he who made the
+first thermometer. But there was one question that he could not answer.
+He found that in a hollow glass tube, closed at one end, water would
+rise thirty-four feet high, but no higher. He could not tell why. A pupil
+of his thought he would try the same thing with the heaviest liquid
+known----"
+
+"That was mercury, wasn't it, uncle?" interrupted Donald.
+
+"Yes; he used mercury, and found that it rose in the tube just thirty
+inches. He knew that the mercury was thirteen and six-tenths times as
+heavy as the water, so he felt sure that it was the pressure of the air
+that made them both rise in the tube, for thirty-four feet is just
+thirteen and six-tenths times thirty inches. But they wanted to see if
+it was really the air, so they took the tube up on a high mountain."
+
+"What difference would that make?" asked Susie.
+
+"Look at the woodpile out there," said her uncle. "Where do you think
+the weight of the wood would be the greater? On the ground or halfway to
+the top?"
+
+"On the ground, of course," answered Susie.
+
+"Well, they found it was the same with the air. As they went up the
+mountain the mercury in the tube fell."
+
+"That showed that the weight on it was less, didn't it, uncle?" said
+Frank. "I think that was a very wonderful discovery, don't you?"
+
+"It was, indeed," replied Uncle Robert, "and that is how the first
+barometer was made."
+
+[Illustration: Barometer.]
+
+"Is that what a barometer is?" asked Donald.
+
+"Yes," was the reply, "simply a glass tube about thirty-three or
+thirty-four inches long, closed at the top, and filled with mercury. It
+is then placed in a small open cup, called the cistern, into which the
+mercury flows until the air pressing on it there will let it fall no
+farther."
+
+"Does it always stay at the same height in the tube?" asked Donald.
+
+"Oh, no," his uncle answered. "Some days the air is heavier than others,
+and so presses harder on the mercury."
+
+"That would make it rise, wouldn't it?" asked Susie.
+
+"Yes, dear."
+
+"So, uncle," said Frank, taking up the Weather Report, "where it says
+'High' here, it means that the air is heavier than where it says 'Low.'
+Is that it?"
+
+"That's right," replied Uncle Robert; "and when the barometer is low we
+know there will be a storm."
+
+"Well"--and Donald stood up and stretched himself--"I wish I could see a
+barometer."
+
+"You shall," said Uncle Robert "I will send for one. You may carry the
+letter to the post office to-morrow when you go for the mail."
+
+
+
+
+CHAPTER VIII.
+
+A WALK IN THE WOODS.
+
+
+It was a beautiful Sunday afternoon. The sun had marked its shortest
+shadows. They were now pointing toward the northeast.
+
+The family had returned from the little village church. Dinner was over,
+and they had all gone into the cool, shady piazza. Mrs. Leonard and
+Susie had settled themselves cozily in one corner and were reading
+together. Mr. Leonard was nodding over the pages of his weekly
+newspaper. Frank, stretched out on the settee, was absorbed in a new
+book, while not far away Donald lay under the spreading branches of a
+spruce tree with Barri by his side. Uncle Robert stood gazing at the
+green woods, which looked so cool and inviting.
+
+"'The groves were God's first temples,'" he said to himself, and then,
+turning to the others, asked, "Who wants to go for a walk?"
+
+"I do," said Frank, springing up. "Come on, Don. Don-ald!" he called,
+"we're going for a walk."
+
+"You'd better come with us," said Uncle Robert to Mrs. Leonard.
+
+"I'll get your hat, mother," cried Susie eagerly, running into the
+house.
+
+"Shall we go to the cornfield?" asked Mr. Leonard, picking up his straw
+hat.
+
+"I think it would be cooler in the woods," said Mrs. Leonard.
+
+"Oh, yes," said Donald, "let's go up the creek to the pond."
+
+The country was in the full glory of early summer. Just beyond the rich
+green of the great cornfield could be seen the peaceful river. The
+yellowing grain on the upland waved gently in the breeze. Under the
+wide-spreading oak trees in the pasture the cows were lazily chewing
+their cuds. A feeling of quiet pleasure filled the air.
+
+"I planted all these trees," said Mr. Leonard as they walked under the
+maples that grew on either side of the road. "It is wonderful how they
+have grown. They were like little sticks when I set them out."
+
+"The one at the end of the row," said Mrs. Leonard, "was planted the day
+Frank was born."
+
+"It is the largest of them all," said Frank.
+
+"That's because it was planted first," said Susie. "I have a tree, too,
+uncle."
+
+"So have I," said Donald. "It is the spruce in the front yard."
+
+"We call them our birthday trees," said Susie. "Mine is the elm by the
+corner of the porch."
+
+"That is a very nice custom," said Uncle Robert. "But the trees grow
+faster than you do."
+
+"They don't have anything to do but grow," said Donald.
+
+When they reached the bridge they paused to look up and down the creek
+valley. Through the trees they caught glimpses of the shining river and
+the waving corn. The creek, a little stream, flowed between the two
+gentle slopes that formed its valley.
+
+"There's a gate under this bridge, uncle," said Donald, "to keep the
+cows from going down the creek to the cornfield. In the fall, after the
+corn is cut, we open it, and let them go to the river."
+
+"How pleasant it is in here!" said Uncle Robert as they walked farther
+into the wood.
+
+"Just see how damp the ground is under these dead leaves!" said Susie as
+she pushed them back from a little violet that she was trying to pick
+with a long stem. "Poor little flowers! How do they ever get through all
+these leaves? It would be so much easier for them if it was just green
+grass."
+
+[Illustration: The bridge. ]
+
+"But then there wouldn't be any flowers," said Mr. Leonard, "or at least
+they would be very different."
+
+[Illustration: HICKORY OAK WILLOW BUTTER-NUT MAPLE WALNUT (leaves)]
+
+"It's the leaves that make the soil so rich," said Frank, digging into
+the ground with a stick. "See how they are mixed all through it!"
+
+"Do you know the names of all these trees?" asked Uncle Robert.
+
+"I do," said Frank. "I can tell every tree in the wood."
+
+"How?" asked Uncle Robert.
+
+"By the leaves is the easiest way," said Frank, "but I know some trees
+by the bark."
+
+"I can tell them by the leaves," said Donald. "Try me."
+
+So as Uncle Robert pointed to them Donald called them all by name. There
+were oaks and maples, hickories, walnuts, and butternuts, and close to
+the creek the overhanging willows.
+
+"Can you tell a tree by its shape when you look at it from a distance?"
+asked Uncle Robert.
+
+"I can tell the willows and poplars," said Frank, "and maples, too."
+
+"The trees in the pasture have a different shape from those in the
+woods," said Uncle Robert. "I mean trees of the same kind. How do you
+explain that?"
+
+"Why, the trees in the pasture have a chance to spread out," said
+Donald. "There isn't so much room in here."
+
+"But these trees are taller," said Frank, "and they are straighter,
+too."
+
+"Can you tell the direction of the winds that blow the strongest and
+longest by the shape of the trees?" asked Uncle Robert.
+
+"I never thought of that," said Frank.
+
+"The wind doesn't blow in the woods," said Donald.
+
+"When we get out into the pasture we'll notice the trees there," said
+Mr. Leonard.
+
+"Isn't this a tiny tree?" said Susie. "I wonder what it is."
+
+"That's an oak," said Frank. "The leaves tell that."
+
+"Oaks grow from acorns," said Donald. "I'm going to dig this up and see
+if it grows like the seeds in the garden."
+
+"What a long root it has!" said Susie as Donald dug about it. "Don't
+take it out, Don. Put the dirt back and let it grow to be a tree."
+
+[Illustration: Oak sprout.]
+
+"How long will it be before it gets as big as these trees, uncle?" asked
+Frank.
+
+"A great many years. Perhaps your father can tell about how old some of
+these trees are."
+
+"I have cut some," said Mr. Leonard, "that were about a hundred years
+old."
+
+"Why, father," exclaimed Susie, "how could you tell?"
+
+"Do you know how the end of a log looks when it is sawed off straight?"
+
+"I do," said Frank. "There are light and dark rings in it."
+
+"Well," was the reply, "one of these rings grows every year."
+
+"So if you count the rings you can tell how old the tree is," said
+Donald. "Isn't that great!"
+
+[Illustration: End of a log.]
+
+"What time of the year do the trees grow the most?" asked Uncle Robert.
+
+"In the spring I should think," said Frank. "That's when the sap begins
+to run."
+
+"What is sap?"
+
+"It must be the water that the trees take up from the ground," said
+Frank.
+
+"We've tapped some maple trees for sap," said Donald.
+
+"And we could see it run right out of the tree," said Susie.
+
+"I've told the children how we used to make maple sugar in New England,"
+said Mrs. Leonard. "Do you remember, Robert, what a quantity of sap it
+took to make just a little sugar?"
+
+"Yes, and I also remember how long I thought it took to boil it down
+into the wax I was so fond of."
+
+"About thirty gallons of sap can be taken from one tree each year," said
+Mr. Leonard.
+
+"But I should think that would hurt the tree," said Frank.
+
+"No," replied Uncle Robert, "for the hole they make is only about an
+inch across. If they were to cut all around the tree, you see, it would
+stop the running of the sap and kill the tree."
+
+"That is called girdling," said Mr. Leonard. "They used to clear off
+hundreds of acres of land in that way when this country was first
+settled. Instead of cutting down the trees, they girdled them near the
+ground. In a very short time they died, because they could get no food
+from the earth. The dead trees lost their strength, and a strong wind
+would blow them over. Then they were piled up and burned."
+
+"How do you know when a tree is dying?" asked Uncle Robert.
+
+"The leaves turn yellow," said Donald.
+
+"But the leaves turn yellow in the fall," said Frank, "and the trees do
+not die."
+
+"The leaves of my spruce don't turn yellow in the fall," said Donald.
+"They stay green all winter."
+
+"What makes the leaves green?" asked Uncle Robert.
+
+No one answered.
+
+"What is the color of the potato sprouts in the cellar?"
+
+"Yellow," said Susie.
+
+"When you take up a board that has lain on the grass, what is the color
+of the grass?"
+
+"Yellow," said Donald.
+
+"Why?" asked Uncle Robert.
+
+"Because they don't get any light," said Frank.
+
+"You know why we put our plants in the south window in winter?" said
+Mrs. Leonard.
+
+"Oh, yes," said Susie, "because the sun shines in at that window."
+
+"Warmth and water and air help trees and plants to grow," said Uncle
+Robert, "but without sunlight their leaves would be yellow and their
+stems and branches weak. The greatest forests on earth are where it is
+very hot and moist. The sun is a wonderful artist, and every leaf it
+paints makes the tree stronger."
+
+"But what makes the leaves turn yellow and red just before they fall
+off?" asked Frank. "Does the sun paint them then?"
+
+"That is a question that no one has been able to answer," replied his
+uncle.
+
+"But how can the sap flow up the tree?" said Donald. "I should think it
+would run down."
+
+"It would unless there was something to draw it up," said Uncle Robert.
+
+"I suppose the sun does that, too," said Frank.
+
+"Where does it go after it reaches the leaves?" asked Uncle Robert.
+
+"Why, back again," said Susie.
+
+"No, it doesn't go back--not a drop," laughed Uncle Robert.
+
+"Does it dry up?" asked Donald.
+
+"What do you mean by drying up?"
+
+"It evap-o-rates," said Donald, who liked to use large words.
+
+"Does it all go into the air?" asked Frank.
+
+"I want you to answer these questions yourselves, children. What do you
+see on the corn leaves in the early morning?"
+
+"Drops of water; but that is dew, isn't it?" asked Frank.
+
+Uncle Robert had a way of stopping or changing the subject when he had
+asked certain questions. He knew that the children would think of them
+again and try to answer them.
+
+"Let's sit down on this log," said Susie. "I want to fix my flowers."
+
+As they sat there squirrels ran up the trunks of the trees and laughed
+at them from the branches.
+
+"That is a good shot," said Frank, pointing to a large fox squirrel.
+"But he knows we won't kill him, and that's the reason he shows
+himself."
+
+"Is it right to shoot the pretty squirrels, Uncle Robert?" asked Susie.
+
+"I thought so when I was a boy. I shot a great many of them then. It was
+fun for me, and I felt very proud when I brought home half a dozen
+grays.
+
+"Once I went home from the city for a summer's rest. I took my gun for a
+stroll in the oak woods where I had shot so many squirrels. I put my gun
+against a tree and lay down upon the leaves. Soon I was fast asleep. I
+dreamed of a group of merry, laughing children running, scampering,
+playing."
+
+[Illustration: The squirrel]
+
+"Then my dream became real--not children, but the gray coats, five or
+six of them, close to me, were running up the trees, jumping from limb
+to limb, scampering over the ground, chasing each other, laughing as
+squirrels laugh, and screaming as squirrels scream. I watched the happy
+playmates, brim full of fun. I have never shot a squirrel since."
+
+
+
+
+CHAPTER IX.
+
+THE BIRDS AND THE FLOWERS
+
+
+The little family party strolled on through the beautiful woods,
+following the windings of the creek that was now a tiny stream.
+
+[Illustration: The creek in the woods]
+
+Here and there were little holes hollowed out by the spring floods.
+Miniature falls gurgled over dead leaves. Graceful ferns fringed
+the creek's banks. Mosses covered the bowlders.
+
+Through the foliage danced the rays of the bright sun, casting wavering
+shadows over the leaf-covered ground.
+
+"Here is the pond!" cried Susie.
+
+But the pond that formed the reservoir of the creek was now nearly
+drained, and in place of water there was a swamp filled with reeds,
+rushes, and grasses. A small clear pool remained in the center.
+
+[Illustration: Blackbirds.]
+
+On the tall reeds swaying to and fro piped a family of blackbirds,
+busily chattering to each other. Overhead in the cloudless sky floated a
+huge hawk.
+
+"In the spring this ground is all covered with water; it makes quite a
+large lake," said Mr. Leonard.
+
+"You thought of draining off the water and turning the pond into a
+cornfield, didn't you, father?" asked Mrs. Leonard.
+
+"Yes," said Mr. Leonard; "by digging a ditch or making the channel
+deeper at the outlet, this would become dry land the year around. The
+soil is deep and rich-better even than the bottom land."
+
+"That would spoil the creek, wouldn't it, father?" asked Frank.
+
+"Yes, it would run in the spring only," said Mr. Leonard.
+
+"Where would the cattle drink in the summer?" asked Donald.
+
+"That's the difficulty. The swamp holds enough to keep the cattle in
+water all summer."
+
+"Would the corn more than pay for the loss of the water?" asked Frank.
+
+"Yes, I think so," answered his father.
+
+"But it would spoil my beautiful creek," said Susie. "Don't do that."
+
+"If this swamp were in New England," said Uncle Robert, "the farmers
+would dig out this rich mud for their poor land."
+
+"Oh," cried Susie, "the blue flags are almost in bloom!"
+
+"There is one all blossomed out," said Donald. "I'll get it."
+
+The boys took an old log and threw it across the wet place, and Donald,
+balancing himself carefully, went out and picked the blooming flag with
+its buds.
+
+"Thank you, Donald," said Susie, as he handed her the pretty flowers.
+"I'll put the buds in water and they will open."
+
+[Illustration: Blue Flag.]
+
+"Do you know the names of all the flowers in your bouquet?" asked Uncle
+Robert.
+
+"Every one of them," said Susie. "This is phlox. There is ever so much
+of it in the woods now. And this is a trillium. Isn't it big and white?
+Here is another, only it is red."
+
+"We used to call the red ones 'wake-robin' in New England," said Uncle
+Robert. "I thought they came earlier than the white ones."
+
+"They do," said Susie. "They've been here a long time."
+
+"The violets are just as pretty as when I came, aren't they?" said Uncle
+Robert. "Do they stay all summer?"
+
+"Not quite," replied Susie. "But they stay a long time in the woods."
+
+"What is this?" asked Uncle Robert, pointing to a pale-pink flower on a
+hairy stem, surrounded by rough green leaves.
+
+"That's a wild geranium," said Susie; "but do you think it looks-much
+like a geranium? I don't."
+
+"No, but here is a seed pod," said Uncle Robert. "It looks like the seed
+of the geranium that grows in the garden. Perhaps that is what gave it
+the name."
+
+[Illustration: Wild geranium.]
+
+"I have a flower that you haven't, Susie," said Mrs. Leonard, holding it
+up for them to see.
+
+"Oh," cried Susie, "a yellow lady's slipper! I didn't know they were out
+yet. Where did you find it?"
+
+"I picked it on the bank near the creek while you were talking about the
+trees," replied her mother.
+
+"I wish I could find a pink one," said Susie, looking around.
+
+"Isn't it too early for them?" asked Uncle Robert.
+
+"They come about the same time as the yellow ones," said Donald, "but we
+don't find very many of them."
+
+"I like the Indian name for that flower," said Mr. Leonard.
+
+"Do you mean moccasin flower, father?" asked Frank. "I like that too."
+
+[Illustration: Yellow lady's slipper.]
+
+"Why don't we call it that?" asked Donald.
+
+"Lady's slipper is easier to remember," said Susie.
+
+"Here are some bluebells, Susie," said Frank, holding up a handful of
+the dainty, graceful blossoms. "Give some to mother, and you may have
+the rest."
+
+"How many blue flowers we have!" said Susie. "There aren't any red ones
+excepting the red trillium, and that's so dark it isn't really red."
+
+"It's more purple than red," said Donald.
+
+"This isn't the time of the year for red flowers," said Mrs. Leonard.
+"They come later in the summer and in the fall."
+
+"I wonder why there are no red ones in the spring," said Susie.
+
+"I saw painted cups along the edge of the timothy meadow yesterday,"
+said Donald.
+
+[Illustration: Moccasin flower.]
+
+"Oh, did you, Don? Were they truly red, or just yellow?"
+
+"No, they were in bloom. They were red."
+
+"Let's go home that way," said Susie, "and get some."
+
+"I wish all the people in New York could know how restful these woods
+are," said Uncle Robert, breathing a long breath of the sweet, pure air.
+
+"It always seems to me more quiet in the woods on Sunday than on any
+other day," said Mrs. Leonard.
+
+"Do the birds know when it is Sunday?" asked Susie.
+
+"If they do," said Uncle Robert, "those blue jays must have forgotten."
+
+"Just hear how they scream!" said Frank.
+
+"They must be up to their usual trick," said Mr. Leonard, "of tormenting
+some other bird."
+
+"Listen!" said Donald. "It's a sparrow hawk they're after. That's the
+sparrow hawk's cry, but it's a blue jay that made it. They always mimic
+them when they chase them. I've watched them lots of times."
+
+[Illustration: Blue jay.]
+
+"I wish we could see them now!" said Frank. "The hawk will turn on them
+soon. Then they'll change their tune."
+
+"They are having a good time shouting and screaming to each other," said
+Susie. "What a horrid noise they make!"
+
+"They scare away the other birds," said Donald.
+
+"How many birds do you know?" asked Uncle Robert.
+
+[Illustration: Robin.]
+
+"I know all the birds that come around the house and the barn," said
+Donald. "There are the robins, sparrows, pewees, wrens, swallows, and
+martins. Then there are the birds in the fields--the larks and the
+crows. The names of some of the little birds in the woods I do not
+know."
+
+"You have left out the woodpeckers," said Frank, "and the thrushes and
+catbirds."
+
+"And the cherry birds, that look like canaries," said Susie.
+
+"Get up early in the morning, just as the sun is rising, and you will
+hear a chorus," said Mrs. Leonard. "It is a regular morning praise
+meeting."
+
+[Illustration: Woodpecker.] "The oriole, or golden robin, is the
+handsomest bird of all," said Donald.
+
+"A great many birds come in the spring which stay only a few days," said
+Frank.
+
+"Where do they come from, and where do they go?" asked Uncle Robert.
+
+"They come from the south, I suppose, where it is warmer. I wonder how
+they know when it is time to start," said Frank.
+
+"And which way to go," added Donald.
+
+"And how they decide where to stop and build their nests," said Mrs.
+Leonard.
+
+[Illustration: Oriole.]
+
+"Very interesting questions, but no one has answered them yet," said
+Uncle Robert. "Migrating birds are all found in the south in winter, and
+we see them in the spring."
+
+"What do you mean by mi-grat-ing birds?" asked Susie.
+
+"Birds that fly from one part of the country to another," said Uncle
+Robert.
+
+"The bluebird is the first to come," said Donald.
+
+"A patch of blue sky," said Uncle Robert.
+
+"You forget the geese that screech over our heads in the early
+spring," said Frank. "They fly in flocks shaped like an arrow."
+
+[Illustration: Bluebird.]
+
+"The 'bobwhite' is the funniest little bird. One comes right up to my
+garden fence. It is a shame to shoot them!" said Susie.
+
+"It is a shame to kill any bird unless you need it for food. Every time
+a bird is killed the farmer loses one of his best helpers. The birds
+work for the farmer from morning to night."
+
+"Oh, now you are making fun, Uncle Robert," said Susie. "The birds don't
+work at all. They just fly around and have a good time."
+
+"The crows don't work for the farmer when they pull up his corn," said
+Frank.
+
+"Nor the hawks when they steal his chickens," added Mr. Leonard.
+
+"The cherry birds steal the cherries, and the sparrows eat the
+strawberries," said Susie.
+
+"You would soon find out how much the birds do if they should all fly
+away," said Uncle Robert.
+
+[Illustration: Crow. ]
+
+"The cankerworms would eat the leaves of the
+apple and other trees, and insects of all kinds would destroy the crops.
+The crow taxes the corn in payment for all the good he does. The hawks
+eat a thousand mice to one chicken--in fact, very few hawks eat
+chickens, anyway. The cherry birds and sparrows should be allowed a
+little toll for all the fruit they save. I want you to read a charming
+book called The Great World's Farm. The author calls birds 'Nature's
+militia.' The morning song of the birds means 'We are going to help the
+farmer to-day.'"
+
+"That's true," said Mr. Leonard. "The farmers are just learning what a
+help the birds are to them. We have found that they eat the grubs, the
+worms, and the bugs before they eat everything else."
+
+"Would there be very many more worms than there are now," asked Susie,
+"if the birds should go away?"
+
+"You don't remember, do you, Susie," said her mother, "how many
+caterpillars there were in the village the year they tried to drive the
+sparrows away?"
+
+"I do," said Donald. "Wasn't it dreadful? Why, Uncle Robert, the leaves
+were all eaten off the trees, and you could hardly take a step without
+squashing a caterpillar."
+
+"Ugh!" said Susie with a shudder. "I'm glad I was too little to remember
+it."
+
+"But the strange part of it was," said Frank, "that out here we hardly
+saw a caterpillar all summer."
+
+"And our trees were never more beautiful," said Mrs. Leonard.
+
+"Perhaps the village sparrows came to visit you," said Uncle Robert.
+
+"They must have," said Donald. "The woods were full of them."
+
+"I have read," said Uncle Robert, "that some small birds eat every day
+as much as their own weight in worms and insects."
+
+"Oh, my!" said Susie. "I wonder how many worms that would be."
+
+"The appetite of the small bird," said Mr. Leonard, looking at Donald
+with a smile, "must be something like that of a small boy."
+
+They had now left the woods and were going toward the timothy meadow to
+get the painted cups. Donald was right. One corner of the meadow was
+bright with the vivid red patches.
+
+The sun was setting when they reached home. As they passed the woodpile
+in the back yard Donald said:
+
+"I wonder how old that wood is! I'm going to see if I can count the
+rings."
+
+"Show them to me, Donald," said Susie. "I never saw them."
+
+Just then the clear, rich song of a bird rang out from the top of a tree
+on the edge of the woods.
+
+"Hark!" said Mr. Leonard. "That is the thrush."
+
+They listened until the song was ended.
+
+"What a lovely walk we have had!" said Susie. "I'm not a bit tired. Are
+you, mother?"
+
+"Well, a little," said Mrs. Leonard, "but we never had a more delightful
+afternoon. Thank you, dear," as Frank brought an easy-chair from the
+house to the porch for her. "Now I shall be rested in a few minutes."
+
+"Let me put your flowers in water with mine, mother," said Susie.
+
+"Tell Jane to bring our supper out here," said Mrs. Leonard. "It is too
+pleasant to go in the house."
+
+"And tell her to be quick about it," said Donald. "I'm starving!"
+
+"As hungry as a sparrow," said Uncle Robert, smiling.
+
+While they were eating, the twilight came on.
+
+"Listen!" whispered Frank, as a queer, clucking sound was heard among
+the bushes. Then came the cry:
+
+"Whip-poor-will! whip-poor-will!"
+
+"I wish I could see a whip-poor-will," said Donald. "They never let me
+get near enough to them to see how they look."
+
+"Let's try this one," said Frank. "It's very near."
+
+On tiptoe they slipped off the porch, but the shy bird heard them and
+flew away. Soon they heard it again:
+
+"Whip-poor-will! whip-poor-will!"
+
+And another one answered from the edge of the cornfield:
+
+"Whip-poor-will! whip-poor-will!"
+
+[Illustration: Whip-poor-will. ]

+
+
+CHAPTER X.
+
+THE THUNDERSHOWER.
+
+
+It had been growing warmer all day. When Susie looked at the thermometer
+at noon she wrote "82 degrees" in her little book. As they sat around
+the dinner table Uncle Robert asked:
+
+"Do you find it hot in the meadow to-day?" "Rather warm," replied Mr.
+Leonard, "but it is fine haying weather. By night we shall have the hay
+in off that twenty acres, and it will be the finest crop of timothy I
+have had in years."
+
+The haying had begun four days before. For a week Mr. Leonard had
+visited the field of timothy daily, and when he found the long heads of
+the graceful grass in full bloom he said:
+
+"It is ready. We must begin to-morrow."
+
+So the next morning the horses were hitched to the mowing machine, and
+Peter drove out to the meadow. The plumy heads of the tall timothy
+swayed on their slender stalks as they bowed before the breeze that
+swept over the meadow, making it look in the sunshine like the rippling
+surface of a quiet lake.
+
+[Illustration: Mowing the meadow.]
+
+It seemed a pity to cut it down, but Peter thought only of the fine hay
+it would make, as he drove around the meadow again and again, each time
+coming nearer the center.
+
+No sound broke the stillness but the "click, click" of the sharp knives,
+at the touch of which the tall grass quivered a moment and then fell.
+
+In the afternoon Donald rode the rake, to which one of the horses,
+strong and steady, was hitched. The horse knew his business. He needed
+no direction from Donald as up and down the meadow he went, with slow
+and even steps.
+
+Donald sat on the small round seat, 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 windrows.
+
+Mr. Leonard and Frank followed with their pitchforks, and piled the
+windrows into big round cocks. The sun shone hot and clear. A strong,
+dry south wind was blowing, and the air was filled with the sweet smell
+of the newly mown hay.
+
+The second day Mr. Leonard rode the machine while Peter and Frank opened
+the hay that had been cocked the day before, so that it would be nicely
+dried. By noon it was all cut.
+
+The next day they raked it up for the last time and began to stow it
+away in the big haymows in the barn, where the very smell of it would
+make the horses hungry.
+
+"Susie and I are coming out to help this afternoon," said Uncle Robert,
+as, after a short rest in the cool porch, the haymakers, started for the
+meadow again.
+
+"We'll take all the help we can get," replied Mr. Leonard.
+
+"I am afraid it is going to rain," said Uncle Robert, as he started a
+little later with Susie for the hayfield. "The barometer has fallen
+since morning."
+
+"But, uncle," said Susie, "I don't see any clouds."
+
+[Illustration: Raking and cocking hay.]
+
+"Watch, and you'll see them before long," returned Uncle Robert. "What
+is that in the west now?"
+
+"It looks like the beginning of a cloud," said Susie.
+
+Mr. Leonard, Peter, and Frank were loading the hay into a big wagon,
+while Donald raked after them.
+
+"There's a shower coming," said Uncle Robert, pointing toward the west.
+
+All paused and looked at the bank of clouds just coming into sight along
+the western horizon.
+
+The air was still and sultry. Great beads of perspiration rolled down
+the faces of the haymakers.
+
+"It's going to rain, sure," shouted Mr. Leonard, "and we must hurry or
+this fine hay will be spoiled. Harness up the horses to the other
+hayrack, Frank and Donald--be quick!"
+
+The boys did not need urging. They felt the need, and ran to the barn.
+
+"Bring some extra pitchforks!" shouted their father after them.
+
+Uncle Robert pulled off his coat, and the spirit of his boyhood days
+came back.
+
+Susie seized a rake and began to gather the scattered hay and pile it on
+the cocks.
+
+The fresh span of horses galloped into the field. Frank brought them to
+a stand between two long rows of haycocks.
+
+How they all worked! The very horses seemed to understand. They started
+with a jump to each new cock, and stood perfectly still as one after the
+other was added to their load.
+
+"It is coming!" shouted Peter, swinging his fork to spread the great
+bundles of hay which came flying up to him.
+
+The clouds looked like mountains with snowy peaks as they rose rapidly
+in the southwest. The mass moved under the sun and the bright silver
+color changed to blackness. Lightning flashes followed one another
+quickly. The low rumbling of thunder stirred the still air.
+
+"It is coming!" cried Donald, as he took the reins to move to another
+cock. "G'long!"
+
+All was hurry and excitement. Mrs. Leonard and Jane appeared on the
+scene with rakes in hand. Barri bounded from horse to horse as if that
+was some help.
+
+Suddenly it grew darker. The leaves began to quiver. A curious light
+crept over the fields.
+
+"There is the wind," shouted Frank. "The rain will be here in a minute."
+
+Clouds completely covered the sky. Black forms seemed to dart out of
+their heavy masses.
+
+"There's a drop," cried Susie.
+
+Then what a wind! Straw hats were whirled away, but there was no time to
+run after them.
+
+"Pile up the hay!"
+
+The great loads staggered.
+
+"Drive for the barn!" shouted Mr. Leonard. "Some of it must spoil, I
+suppose. We have done our best."
+
+The horses moved off on the run, Frank's team ahead.
+
+A roll and a crash of thunder followed a zigzag flash.
+
+The hay was under cover, and the rain poured down.
+
+[Illustration: The coming storm.]
+
+They reached the porch just as it began to fall thick and fast. A moment
+more and it came down in floods, while at the same time the darkness
+passed away.
+
+"How cool it is growing!" said Mrs. Leonard.
+
+"It is twelve degrees cooler than it was at noon," said Donald, looking
+at the thermometer. "See, the wind has changed. It is from the northeast
+now."
+
+Frank went into the dining-room, and when he came back he said, "The
+barometer has risen two-tenths of an inch since we looked at it last."
+
+It seemed to rain harder than ever. The water was driven in sheets
+before the strong northeast wind. A stream began to run down the garden
+path. A vivid flash of lightning was followed quickly by a loud crash of
+thunder.
+
+"That struck somewhere near," said Frank.
+
+"I believe it was over in the wood," said Mrs. Leonard.
+
+"See," said Uncle Robert in a few moments, pointing to a line of light
+in the western sky, "it is clearing already. The shower will soon be
+over."
+
+The light in the west grew rapidly. The lightning became less frequent.
+The thunder rolled farther and farther away. The rain fell less and less
+heavily. The weather vane that had pointed to the northeast began to
+waver, and then turned toward the southwest again. It rained steadily
+but more gently as the clouds rolled away eastward.
+
+And then the sun, lower now by two hours than when it was first hidden
+by the cloud, shone out clear and bright. Instantly everything glistened
+as with millions of diamonds. Even the air seemed to be filled with them,
+as though each raindrop was turned into a jewel as it fell.
+
+Uncle Robert went to the front of the house and looked toward the dark
+cloud that was now piled up in the eastern sky.
+
+"Come and see the rainbow!" he called.
+
+As they looked at the bright and perfect arch that lay against the dark
+mass of clouds, Susie asked, "What makes rainbows, uncle?"
+
+"It is the sun shining on the rain," replied Uncle Robert "This
+beautiful sunlight is made up of many, many rays. These rays fly from
+the sun as straight as arrows from a bow, unless something comes in
+their way to stop them. It seems as though such sharp little arrows of
+light would go right through raindrops. But they don't. They glance off
+the little round balls of water and bound up again like rubber balls.
+
+"Now you know if you throw a ball straight down at your feet it bounds
+back into your hands. If you throw it from you, when it strikes the
+ground it bounds farther away. It is just so with these little arrows of
+light that we call rays. If the sun is high, as it is at noon, the rays
+are thrown back to it again. That is why we never have rainbows at noon.
+But when the sun is low, as it is now, instead of going back to the
+place they came from, they bound up against that cloud, and so make the
+wonderful rainbow."
+
+"But, uncle," asked Donald, "why do we see so many colors in the
+rainbow? They are not in the sunlight."
+
+"Oh, yes, they are," was the answer. "These rays of light are of the
+same colors that we see in the rainbow. It takes all of them mixed
+together to make the clear white light which we call sunlight, and
+without which nothing could live or grow.
+
+"As the raindrops throw them up against that cloud, they are separated
+again, because some colors are more easily bent than others. The red,
+you see, is the highest and the violet the lowest in the bow. The
+raindrops make a prism. You have seen a prism. But through the prism the
+colors are turned the other way; the red is lowest and the violet
+highest."
+
+"How fast the rainbow is fading away!" said Susie. "I wish it would
+stay."
+
+"The rain is over," announced Donald, leaving them and walking out
+toward the garden. "The sky is quite clear."
+
+"It is getting warm again," said Frank, looking at the thermometer, "but
+it does not feel hot as it did before the rain."
+
+"The barometer is just where it was this morning," said Susie, coming
+from the dining-room.
+
+"It is drying off very fast," said Uncle Robert. "Let us walk out and
+see how the garden stood its drenching."
+
+"Put on your rubbers, Susie," called Mrs. Leonard from the house.
+
+As they crossed the yard they passed a pan in the bottom of which the
+water stood an inch or more deep.
+
+"That shows how much rain fell," said Uncle Robert, pointing to the pan.
+
+"Do you mean if it had stayed on the ground where it fell it would have
+been that deep all over?" asked Susie. "Would that have been very much?"
+
+"I think it would," was the smiling reply. "You might try to find out
+how much fell on the garden alone if it was an inch deep all over."
+
+Susie shook her head.
+
+"I don't know how," she said.
+
+"Uncle," said Frank, "in the weather reports they always tell how much
+rain falls, even if it is only a small part of an inch. How can they
+tell when it is so little?"
+
+"They have what is called a rain gauge, by which a very small amount of
+rainfall can be measured. By the way, we might have a rain-gauge of our
+own. It would be easy to make one with the help of a tinsmith. Is there
+a tinsmith in the village?"
+
+"Yes," answered Frank, "but I don't believe he has much to do."
+
+"So much the better for us," laughed Uncle Robert. "Susie, while these
+other people are busy tomorrow, shall we drive to the village and see if
+we can get the tinsmith to help us make a rain-gauge? I have a little
+book somewhere that tells just how it should be done."
+
+Susie was delighted at the thought of such a day with Uncle Robert, 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 come.
+
+
+
+
+CHAPTER XI.
+
+THE VILLAGE.
+
+
+The next morning Frank harnessed Nell for Uncle Robert and Susie to
+drive into the village to see the tinsmith.
+
+It was a delightful ride through the woods and the fields washed clean
+by the rain. The birds were singing gayly. The air was fresh and clear.
+Long shadows lay along the road.
+
+The tinsmith was sitting by his open door, tilted back in an old wooden
+chair. As Nell stopped, he brought his chair down on its four legs and
+said:
+
+"Good morning."
+
+Uncle Robert lifted Susie out of the wagon and hitched Nell to a post.
+The tinsmith rose to his feet, smiling to Susie, who said:
+
+"This is my Uncle Robert, Mr. Mills. We've come to have a rain-gauge
+made."
+
+"Good morning," said Uncle Robert, turning to Mr. Mills, who looked as
+if he thought rain gauges were not exactly in his line. "Can you spare
+us a little time this morning? Susie must have her rain-gauge before the
+next shower."
+
+"Come right in," said Mr. Mills, "and tell me what your rain-gauge looks
+like. I never heard of such a thing."
+
+With Uncle Robert's careful direction he soon understood what they
+wanted. They saw him well started in the work, and then Uncle Robert
+said:
+
+"Come, Susie, let's go to the post office.--How long before the
+rain-gauge will be finished?" he asked of Mr. Mills. "Shall we have time
+to get dinner?"
+
+"I think I can have it ready by two o'clock," answered Mr. Mills.
+
+"Then we'll take Nell to the hotel," said Uncle Robert.
+
+They drove slowly under the big cottonwood trees which shaded the
+street.
+
+"Isn't it nice that it takes such a long time to make a rain-gauge?"
+said Susie. "Here we are at the hotel now, Uncle Robert. It's such a
+little way."
+
+From the hotel they strolled to the store, the center of life and
+interest in the village.
+
+[Illustration: The village street.]
+
+One corner of the store was taken up by the post office. Back from that
+ran long lines of shelves which reached to the ceiling. Beneath them
+were bins for flour and sugar. On the lower shelves were canisters of
+tea, coffee, and spices, and glass candy jars, which looked very inviting
+to Susie. Some were filled with gay-striped sticks. There were also jars
+of peppermint lozenges, star--and heart-shaped, with pink mottoes on
+their white faces.
+
+On the upper shelves were rows upon rows of cans covered with gay
+pictures of fruits and vegetables.
+
+Opposite the groceries were long shelves of dry goods. A glass case at
+one end of the counter was filled with bright-colored ribbons.
+
+In the darkness at the back of the store stood the barrels of vinegar,
+molasses, and kerosene oil. Above them hung rows of well-cured hams and
+sides of bacon. Near the barrels stood an old rusty stove which bore the
+marks of long use.
+
+Uncle Robert asked for the mail. Susie looked longingly at the glass
+jars upon the shelf, trusting that Uncle Robert would understand her
+even if she didn't say anything.
+
+"We must have some candy," he said. "Tell Mr. Jenkins what you would
+like, Susie, while I look at my letters."
+
+Susie carefully picked out three sticks of peppermint, three sticks of
+lemon, and three of cinnamon.
+
+"If you please, I'd like some of the mottoes, too."
+
+Mr. Jenkins handed down the jar, spread out a clean sheet of wrapping
+paper, and turned out the candies.
+
+Susie selected a dozen hearts, rounds, and stars, with different
+mottoes, and then wondered if she ought to have lemon drops, too.
+
+"Do you think I have enough, uncle?" she asked.
+
+Uncle Robert knew pretty well what little girls like.
+
+"No, Susie," he said, "you have forgotten the lemon drops, and, let me
+see, nut candy--we must carry home enough for mother and the boys."
+
+Just then a little girl in a pink sunbonnet, carrying an oil can in her
+hand, came through the open door.
+
+"How d' do, Susie," she said, with a shy glance at Uncle Robert.
+
+"How d' do," said Susie. "Have some of my candy, Jennie?" holding it out
+to her. "Uncle Robert bought it for me. There he is," in a loud whisper.
+
+"Good morning, Jennie," said Uncle Robert, putting his letters in his
+pocket. "You haven't been out to see Susie since I have been here."
+
+"It's Jennie's mother who had the nasturtiums last year," said Susie.
+"Have you any now Jennie?"
+
+"Yes, but they don't grow well this year," answered Jennie.
+
+"Perhaps you need new seeds," said Uncle Robert. "They are apt to do
+better if they are raised on different soil."
+
+"I have some nasturtiums this year, Jennie," said Susie. "They are just
+beginning to blossom. I'll save you some seed if you want me to."
+
+"Come out some day and see Susie's flowers, Jennie," said Uncle Robert
+kindly, as they left the store.
+
+"Good-by, Jennie," said Susie.
+
+"Time for dinner," said Uncle Robert. "I'm hungry."
+
+Susie's eyes danced.
+
+They went into the dining-room and sat down at the long table. Through
+the window they could see the hotel garden from which the flowers on the
+table had been gathered.
+
+"What shall we do now?" asked Uncle Robert as, after dinner, they stood
+upon the porch, looking up and down the street.
+
+No sound was heard but the sleepy noonday song of the grasshopper and
+the occasional rattle of a wagon going down to the store.
+
+"Let's go to the mill," said Susie.
+
+"The mill wasn't running when we passed there this morning," said Uncle
+Robert. "Suppose we wait until some time when the boys are with us. Then
+we can go all through it, and see just how wheat is changed into flour."
+
+"Oh, yes," said Susie, "that will be the nicest."
+
+"We might go to the station and see the train come in," suggested Uncle
+Robert, looking at his watch.
+
+"Oh, that's fun! Come on, uncle," cried Susie, running down the steps.
+"See, they are all going down now!"
+
+"All right," said Uncle Robert, "but don't hurry; there's plenty of
+time."
+
+As they looked down the track they could see the steel rails gleaming in
+the hot sunshine. The two shining lines stretched away until they seemed
+to meet in the distance.
+
+In the other direction a faint line of smoke appeared over the trees. It
+grew more and more distinct, until at last an engine rounded the curve
+and came puffing heavily up the track, pulling a long line of cars
+behind it.
+
+"That's a freight train," said Uncle Robert.
+
+"It stops here to let the passenger go by," said the station master, who
+stood near. "Expecting some one to-day, sir? The train isn't due for ten
+minutes."
+
+"Not to-day," replied Uncle Robert. "Do many trains stop here?"
+
+"Not many," said the station master as he hurried away to the switch.
+
+[Illustration: A freight train.]
+
+The great engine, drawing its heavy load after it, turned into the side
+track. When the small caboose at the end had passed the switch a man,
+who was running upon the tops of the cars, waved his arms and the long
+line stood still.
+
+"The engine breathes hard--just like Barri after a long run," said
+Susie. "I wonder what is in all these cars, uncle."
+
+"Here is one marked 'Furniture,' from a large factory in Grand Rapids,"
+said Uncle Robert, reading the white card that was tacked on the side.
+"It is going to a town in Nebraska."
+
+"What funny cars these open ones are!" said Susie; "the ones with the
+shelves in. What are they for? They're empty, too. I shouldn't think
+they'd want to drag empty cars about."
+
+"These are the cars poultry is shipped in," explained Uncle Robert.
+"Perhaps they have been to Chicago with chickens for the market, and are
+on the way back to the place they came from for more."
+
+"How many of these big yellow cars there are!" said Susie. "They all
+have re-frig-re-frig--"
+
+"Refrigerator," prompted Uncle Robert.
+
+"Oh, I know what a refrigerator is," said Susie. "It's an ice box. Are
+these cars ice boxes, uncle?"
+
+"Yes; the great packing houses at the stock yards in Chicago ship beef
+all over the country in them. The fruit from California comes in
+refrigerator cars, too."
+
+"There's the train!" cried Susie, "and here comes Mr. Jenkins with the
+mail."
+
+The train came rushing on. Susie thought it was not going to stop. But
+suddenly it slowed up. The conductor leaped upon the platform. The train
+stood still. Heads were thrust out of the windows. A few passengers
+alighted. Brakemen ran along the platform.
+
+"All aboard!" shouted the conductor, waving his hand to the engineer,
+who was leaning out of the cab window watching for the signal.
+
+"Ding-dong, ding-dong, puff, puff, toot, toot," and the train was off.
+
+"Now we'll go and see if there is any mail for us," said Uncle Robert.
+"Then we'll go to the tinsmith's."
+
+[Illustration: Rain-gauge.]
+
+The rain-gauge was just finished. So Susie waited in the shop while
+Uncle Robert went to the stable for Nell, who pricked up her ears when
+she saw him. She was beginning to think she had been forgotten.
+
+It was late in the afternoon when they reached home. Mrs. Leonard and
+the boys were looking for them when they drove in at the gate.
+
+It took some time to choose just the right place for the rain-gauge, but
+at last they decided upon a little rise of ground that lay between the
+house and the orchard.
+
+There was first the funnel-shaped receiver, one and one-half inches deep
+and eight inches in diameter. Below this was a tube two and five-tenths
+inches in diameter and twenty inches long. At the top of this tube,
+close to the receiver, there was a small hole.
+
+"What is that hole for?" asked Donald.
+
+"So if it rains more than enough to fill this tube," explained Susie,
+who knew all about it, "it can run out of the hole."
+
+"Then it will be lost," said Donald.
+
+"No," replied Uncle Robert, "it is to be set inside of this cylinder,
+which is twenty-three and one-half inches long, but only six inches in
+diameter, and so is smaller than the top of the receiver.
+
+"The water that runs from that hole falls into this. By measuring it in
+the small tube, and adding it to what the tube held before, we can know
+how much there is in all. One inch in the tube would be one-tenth of an
+inch in the receiver."
+
+"Then twenty inches, or the tube full, would be two inches in the
+receiver," said Frank.
+
+"Yes," said his uncle; "but how shall we make this stand up?"
+
+"We might pile stones around it," suggested Donald.
+
+"That will be a good way," said Uncle Robert.
+
+There were some stones in a pile near the orchard fence. Frank and
+Donald picked them up and placed them about the rain-gauge until it
+stood firm.
+
+"Well, these stones are of some use after all," said Frank.
+
+"I'm glad of it," said Donald. "It seemed as though we should never get
+them all picked up. I believe stones grow."
+
+"These stones tell a wonderful story," said Uncle Robert, smiling.
+
+"Oh, uncle, when are you going to tell it to us? To-night?" asked Susie.
+
+"Not to-night, my dear. You have had stories enough for one day," and
+Uncle Robert took her by the hand and started for the house.
+
+"We have a regular weather bureau of our own now," said Donald. "I hope
+it will rain all day long to-morrow."
+
+
+
+
+CHAPTER XII.
+
+A DAY ON THE RIVER.
+
+
+"Father, can't we have a picnic on the river?" asked Susie.
+
+"Please, do let us have a picnic," said Donald.
+
+"I think you may," said Mr. Leonard. "You might have it to-morrow. I
+won't need the boys."
+
+"Hurrah!" cried Donald, and Susie skipped and danced for joy.
+
+"We'll have to have a nice lunch," said Frank.
+
+"What shall it be?" asked Mrs. Leonard.
+
+"Oh, we can take some ham sandwiches--"
+
+"And some cake and jelly," put in Susie.
+
+"And some cold chicken and boiled eggs," added Donald.
+
+"Oh," cried Susie, "let us take our eggs along all fresh and boil them!
+We can take a little pail and--"
+
+"I'll tell you what we'll do," interrupted Frank. "We'll take some salt
+pork, and catch some fish, and have a fry."
+
+Frank looked at the barometer and said it was going to be a nice day.
+The sun was setting clear and bright. The children went to bed happy and
+dreamed of the fun to-morrow.
+
+In the morning Susie rushed out to see if it was good weather. The sun
+was shining brightly, and she turned and looked at her long shadow that
+reached clear over the barn. The direction of the shadow was southwest.
+
+Donald took a tin can and went out into one corner of the garden, where
+the soil was dark, rich, and damp, and with a shovel dug up great mud
+worms, and almost filled his can.
+
+Frank got out two cane poles, rigged the lines and hooks, and put on the
+sinkers.
+
+"I want to catch a fish," said Susie.
+
+"All right," said Frank; "we'll cut a pole for you when we get on the
+island. We shall not fish till we get there."
+
+Uncle Robert watched the enthusiasm of the children with a pleasant
+smile. Mrs. Leonard and Susie put up the lunch.
+
+"Put in a paper of salt for the fish, please," called Frank.
+
+"Don't believe you will catch many fish," said Mr. Leonard. "You know
+the last time you went you didn't catch any."
+
+"It is not a good day for fish," said Uncle Robert; "it is too bright."
+
+"We'll get some sunfish, anyway," said Donald, "and perhaps we shall
+catch a perch or two and a catfish."
+
+At last all was ready Frank took the oars from the beams of the shed,
+Uncle Robert carried the big basket, Donald followed with the fish poles
+and the can of worms, while Susie brought up the rear with a small tin
+bucket.
+
+Away they went, down the slope and over the bottom land to the mouth of
+the creek, where the boat was moored. Soon they glided out from the
+shore under Frank's steady stroke.
+
+"We will go up on this side, where it is easier to row," he said. "The
+current is on the other side next to the bank."
+
+"Why do you suppose the current is over there?" asked Uncle Robert.
+
+"I don't know," said Frank. "Last spring we had a big flood, and the
+current was so strong that it took away a lot of earth from that bank.
+The earth fell down into the river and was carried away. Mr. Davis lost
+a good deal of land."
+
+"Tell me about the flood, Frank," said Uncle Robert.
+
+"Last March the ice broke up in the river and went tearing downstream in
+great blocks," began Frank. "Just below the dam, between the island and
+that shore," pointing to the woods, "it piled up until there was a big
+ice jam. You could cross over to the island on foot. Then the water began
+to rise until it was nearly even with the top of the dam. At first it
+went round close to the ridge. You see the land is lower there. The part
+of our cornfield next to the river was an island. Then the water rose
+higher, and spread all over the bottom land. It made the mouth of the
+creek close to the slope, and the water came up around the trunks of the
+trees.
+
+"On the other side, where the current is, it didn't get over the bank,
+but it tore away lots of earth. Three big trees fell into the water and
+were carried down the river. Ever so many trees came down. Peter and I
+caught a lot and piled them up for firewood."
+
+"Don't you remember, Frank," said Susie, "two or three sheds came down,
+too?"
+
+"The miller thought it would carry away the mill," said Donald.
+
+"The water looks pretty clear now. How did it look then?" asked Uncle
+Robert.
+
+"At first it was clear," said Frank. "Then it got just like coffee."
+
+"That was the dirt in the water," said Donald.
+
+"When the water went down," continued Frank, "the bottom land was all
+covered with the stuff the river left. Father says the dirt it brought
+makes the land better."
+
+"What do you suppose made the freshet?" asked Uncle Robert.
+
+"Oh, they said it was the snow melting, away up the river," answered
+Donald. "The snow was gone here, but we had lots of rain."
+
+"Where is the deepest part of the river?" asked Uncle Robert.
+
+"It is quite deep on the other side," said Frank, "but it is shallow
+over here. Farther down it is deeper in the middle."
+
+"Where is the current down there?" asked Uncle Robert.
+
+"In the middle of the river," said Frank.
+
+"When we go in swimming we can wade out here a long ways before we go
+over our heads," said Donald.
+
+"I wish I could swim," said Susie.
+
+"You should learn," said Uncle Robert. "The boys could easily teach
+you."
+
+They rowed steadily up the river. At last they reached the island and
+landed. It was long and narrow, covered with trees and green grass. Here
+and there low bushes grew down to the water's edge, while at the upper
+end there were many boulders, stones, pebbles, and clean white sand.
+
+[Illustration: A string of fish.]
+
+They brought up the basket and put it in a cool place under a tree.
+
+"Now for the fishing!" said Frank.
+
+Up the river they could see the dam, and on the left of the dam the
+flour mill.
+
+"There is a nice big pond up above the dam," said Susie. "We ought to go
+up there some day."
+
+"I think it is better fishing there," said Frank, "but we would have to
+drag the boat around the dam."
+
+Uncle Robert stretched himself under the shade of an elm tree. Susie
+rolled up her sack and put it under his head. The boys went off to try
+their luck at fishing. They cut a pole for Susie, but she soon tired of
+sitting still, and came back to pick up sticks for the fire so that
+everything would be ready to fry the fish.
+
+When the boys came back they brought three little sunfish, two perch,
+and one funny-looking fish with horns, which Frank said was a catfish.
+
+Frank and Uncle Robert dressed the fish, while Donald rowed across the
+river to a place where he knew there was a spring, and soon returned
+with a pail of clear, sparkling water.
+
+Susie spread the cloth in a nice shady place, and unpacked the basket.
+The eggs were boiled in the tin bucket over the fire. Frank fried the
+fish, and at last dinner was ready.
+
+"Oh, isn't this fun!" said Susie.
+
+"Grand!" said Frank.
+
+"I'd like to be an Indian and live in the woods all the time," said
+Donald.
+
+"We could make a fort," said Frank, "on that bank of the island and
+mount cannon, and not allow any ships to come up the river."
+
+"Oho!" laughed Donald. "Ships don't come up this river. The water isn't
+deep enough."
+
+"That doesn't matter," said Susie; "we could play they do."
+
+After the luncheon was over and the basket packed again they sat about
+under the trees.
+
+"What a good view of the dam there is from here!" said Uncle Robert.
+
+"I know why they built the dam there," said Frank. "Just above the dam
+the water was quite swift."
+
+"What makes the water swift?" asked Donald.
+
+"Because the bed of the river slopes more there than down here," said
+Uncle Robert; "and in places on rivers where there are rapids they build
+dams in order to use the water for the mills."
+
+"Oh, yes, I know how they use the water," said Donald. "They have a
+sluice, and they lift the gate, and the water comes through, and that
+turns the mill wheels."
+
+"In some rivers there are ponds larger than that pond up there, where
+there are no dams," said Uncle Robert.
+
+"Yes," said Frank, "there is a little lake down the river. We will go
+there some day. It is good fishing. How much better our corn looks than
+the corn on that hill over there! I tell you, it takes bottom land like
+ours to raise good corn."
+
+"What makes the corn such a beautiful green?" asked Susie.
+
+"That is quite a question," said Uncle Robert. "We will try and find out
+some day. But I want to know what makes the bottom land richer than the
+land up on the prairie?"
+
+"Well," said Frank slowly, "I suppose that the dirt brought down by the
+river and spread out over it makes it richer."
+
+"Where does that dirt come from?"
+
+"Way up the river."
+
+"If I should call the bottom land a flood-plain," said Uncle Robert,
+"would you know why?"
+
+"Oh, I know," said Donald. "Because the water covers it when there is a
+flood."
+
+"Now what made that flood-plain?"
+
+"Wasn't it always there?"
+
+"No," said Uncle Robert. "The river made it."
+
+"How could the river make the flood-plain?" asked Susie.
+
+"Why, you told me a moment ago that the river brought down great
+quantities of dirt and left it all along the shores," said Uncle Robert.
+
+"But it wouldn't bring down enough to make all that field, would it?"
+asked Donald.
+
+"The river is a great worker," said Uncle Robert. "It is at work now,
+and has been working for many, many long years. It has not only made
+this flood-plain, but many others. Sometimes the river carries this dirt
+clear out into the sea, and sometimes it piles it up at its mouth so
+that a delta is formed."
+
+"Oh, yes," said Donald, "we studied about that in geography when we had
+school, but I didn't know a delta was made that way."
+
+"Are there any deltas in this part of the river?" asked Susie.
+
+"There may be," replied Uncle Robert, "wherever one stream flows into
+another."
+
+[Illustration: The mill and dam.]
+
+"Is there one at the mouth of our creek?" asked Frank.
+
+"We will look when we go back," replied Uncle Robert. "Shall we take a
+walk now?"
+
+When they reached the upper end of the island they sat down on some
+large boulders that formed part of the tiny beach. Just above them was
+the flood of water pouring over the dam. The bright sunshine made the
+foam look white and glistening, lighted here and there with colors of
+the rainbow.
+
+The water rumbled and roared as it rushed out of the mill pond. To the
+left were the flour mill and the village. They could hear the mill wheel
+turning. They could see a little white church half hidden among the
+trees.
+
+A kingfisher swept by them with a voice like a watchman's rattle.
+
+"He knows how to catch fish better than we do," said Donald.
+
+Susie picked up some pebbles and put them in her apron. She tried to get
+a number of colors. Some were nearly red, some were blue, and some were
+white.
+
+"Can you find one that is exactly round?" asked Uncle Robert.
+
+"Here's a white one that's almost round," and Susie held up a quartz
+pebble.
+
+"Where do you suppose this little white pebble came from?" asked Uncle
+Robert.
+
+"Did it come from away up the river--a long way?" said Donald.
+
+"I think so. One day this pebble was a part of some rock or quarry. How
+it was broken off, how it came down, how it was made round, is well worth
+studying."
+
+"Oh, tell us about it, please," begged Susie.
+
+"We'll read about it together," said Uncle Robert, "in the Big Book."
+
+"What book?" asked Donald.
+
+"The book that lies all around us, which was written by the Creator of
+the world," said Uncle Robert. "We are reading a page of it now."
+
+"Just under the current out there," said Frank, "the bed of the river is
+covered with all kinds of stones. Some of them are as big as these
+boulders. I suppose the river brought them down."
+
+"What do you think makes the pebbles round?" asked Uncle Robert.
+
+"Maybe the river wears off the rough edges," suggested Frank,
+thoughtfully.
+
+"Yes," said Uncle Robert, "the current of the river rolls them over and
+over on the river bed, and they rub and grind against each other."
+
+"What becomes of the stuff that is worn off from them?" asked Frank.
+
+"Don't you see it--there?" said Uncle Robert, pointing to the beach.
+
+"Oh, you mean the sand," said Donald, taking up a handful and examining
+it.
+
+"Is that the way the nice white sand is made?" asked Susie.
+
+"That's what you meant when you said the river worked," said Frank. "Did
+these boulders come down the river too?"
+
+"The story of the boulders," said Uncle Robert, "is different from the
+story of the pebbles. The water helped grind the pebbles, but it took
+ice to make the boulders."
+
+"Ice!" the children all exclaimed.
+
+"Yes, ice. A long, long while ago this land was covered by a great
+river, or sea of ice, and that was the time these boulders were made,"
+said Uncle Robert.
+
+"Can we read about that in the Big Book?" asked Donald.
+
+"Some of it," said Uncle Robert. "There are many wonderful stories in
+this beautiful world--stories more wonderful than any fairy tale. But we
+must go home now, children; it's getting late."
+
+The setting sun threw long shadows of the trees over the river as they
+rowed home, and the happy day was done.
+
+
+
+
+CHAPTER XIII.
+
+A RAINY DAY.
+
+
+It was raining, but no one was surprised. They had expected it.
+
+The day before had been one of those warm, midsummer days, beginning
+with a clear sky and a strong south wind. By noon heavy white clouds
+that looked like heaps of down floated slowly overhead.
+
+[Illustration: The weather vane.]
+
+The weather vane, which in the morning had pointed to the south, turned
+from side to side, as though uncertain which direction it liked best.
+Toward afternoon it seemed to settle the question in favor of the east.
+
+The clouds did not rise higher and become thinner and more scattered, as
+such clouds do if the weather is fair. They kept their white, billowy
+edges, and rested heavily on straight bands of dull gray.
+
+When the sun set, the scroll--like edges of the clouds were tinged with
+gold and rose color, but under the glittering fringe remained the solid
+banks of gray and misty purple.
+
+The thermometer had been high all day, for it was very warm. The
+barometer had slowly but surely fallen.
+
+Then, too, the Weather Report, just received, told of a storm that had
+started in the southwestern part of the country and was moving
+northeast. Uncle Robert had said, at the rate it was traveling, it might
+reach them some time the next day.
+
+And now it was raining in a quiet, steady way. The clouds had lost their
+billowy whiteness. They were one dull, heavy, unbroken mass of gray. The
+wind blew steadily from the southeast.
+
+A rainy day was before them.
+
+"The very thing we need," said Mr. Leonard. "The corn is just ready for
+it, and the pastures are beginning to look pretty dry."
+
+"Let's go fishing, Don," said Frank. "I'll go and dig some worms while
+you get the lines ready."
+
+"Say we do," said Donald, starting off at once.
+
+"Do you want some company, boys?" asked Uncle Robert, smiling.
+
+"You bet-ter believe!" said Donald, catching himself just in time.
+
+"Hurrah for the rainy day!" cried Frank as he pulled on his rubber boots
+and coat and went out to dig the worms.
+
+"Shall we take the boat?" asked Uncle Robert.
+
+"Oh, yes," said Donald. "I'll get the oars."
+
+"We'll have fish for dinner to-day, mother," said Frank.
+
+"Be sure you come back in time, then," said Mrs. Leonard, smiling.
+
+"I wish I was a boy and could go fishing in the rain," said Susie as she
+watched them start off.
+
+Down the hill they went, and Susie, watching them from the front porch,
+saw them push the boat from the landing and throw out their lines as
+they drifted down the stream. Then the trees hid them from sight.
+
+It was dinner time when they returned.
+
+"I told you we'd have fish to-day," said Frank triumphantly, holding up
+a string of bass and perch.
+
+"You boys will have to clean them," said Mrs. Leonard. "Jane is ready to
+cook them now."
+
+"Come on, Don," called Frank. "My, won't they be good!"
+
+In the afternoon it ceased to rain. It became lighter and the clouds
+looked higher and thinner.
+
+"It's going to clear off," said Susie, going to the window.
+
+"I wonder how much rain has fallen," said Uncle Robert.
+
+"I'm going to look at the rain-gauge," said Frank.
+
+"I'll go too," said Donald.
+
+When they came back they said there were fifteen inches of water in the
+measuring tube, which, in the receiver, would be an inch and a half.
+
+"That would just fill it," said Donald.
+
+"Does that mean," asked Susie, "that if the rain had stayed on the
+ground it would be an inch and a half deep all over?"
+
+"Yes," answered Uncle Robert.
+
+"Would that be very much?" she asked, taking the rod by which the rain
+in the gauge was measured and finding the mark for an inch and a half.
+
+"We might find out how much it would be on Susie's garden," said Uncle
+Robert. "Does any one know how large the garden is?"
+
+No one knew.
+
+"Let's get father's tapeline and measure it," said Frank.
+
+"Oh, do," said Susie, always interested in anything about her garden.
+
+When they came in Donald said:
+
+"It is muddy, but it's beginning to dry off in some places already."
+
+"How big is the garden?" asked Susie.
+
+"It is forty feet one way," said Frank, "and twenty-five feet the
+other."
+
+"Take your paper and pencil, Frank," said Uncle Robert, "and draw a plan
+of it. You might make one inch for every ten feet, and see how that will
+come out."
+
+Frank took the paper, pencil, and ruler, and soon he said:
+
+"It makes it four inches long and two inches and a half wide."
+
+"But remember," said Uncle Robert, "that means forty feet long and
+twenty-five feet wide."
+
+"I'll write it down," said Frank; "then we'll remember."
+
+So he wrote "40" on the long side and "25" on the short one.
+
+"But we must find out how many square feet there are on the whole
+surface," said Uncle Robert.
+
+"Well," said Frank, "there are forty this way."
+
+"So we might think of it as a row across the garden of forty square
+feet, might we not?" suggested Uncle Robert.
+
+"Yes," said Frank; "and if we do that there will be twenty-five rows
+just like it, won't there?"
+
+"Exactly," said Uncle Robert. "How many does that make in all?"
+
+"Twenty-five forties," said Frank, pencil in hand. "Why, that's just one
+thousand."
+
+"That sounds pretty big," said Susie.
+
+"Especially when you think of the weeds," said Uncle Robert, smiling,
+"How many square inches would that be, Frank?"
+
+"Well," said Frank, "a foot is twelve inches long, and if it is square
+it is twelve inches wide, too."
+
+"Then," said Uncle Robert, "if you call them rows of twelve square
+inches, how many rows would there be?"
+
+"Why, twelve," said Donald.
+
+"And so it would be--"
+
+"One hundred forty-four," said Frank.
+
+"Then," said Uncle Robert, "if there are one hundred forty-four square
+inches in one foot, how many in one thousand feet?"
+
+"One hundred forty-four thousand," said Frank, after a moment's thought.
+
+"But the rain-gauge says that an inch and a half of rain has fallen,"
+said Uncle Robert, "and when an inch is as deep as it is long and broad,
+it is called a cubic inch. How much would one and one-half cubic inches
+be?"
+
+"If this is one inch," said Frank, looking at the paper, "half an inch
+deep would be half of this, and that, added to this, would be an inch
+and a half. Isn't that right?"
+
+He went to work again, and after a few minutes' silence he said:
+
+"It makes two hundred and sixteen thousand inches in all."
+
+"What kind of inches did we call them, Donald?"
+
+"Cubic inches," said Donald.
+
+"If you were to bring a pail of water from the spring," said Uncle
+Robert, "would you say you had so many inches of water?"
+
+"No," said Frank, "it would be quarts, or gallons, or something like
+that."
+
+"Do you know how much a quart or gallon is, Susie?" asked Uncle Robert.
+
+"Mother has a quart cup in the pantry," said Susie, "that she measures
+the milk in sometimes, but I don't know how much a gallon is."
+
+"My new milk pail," said Mrs. Leonard, who sat beside the window sewing,
+"holds just two gallons."
+
+"Let's see how many quarts it takes to fill it," said Susie.
+
+So they went into the kitchen, and Susie dipped the water with the quart
+cup into the tin pail.
+
+"Eight," she said, when the pail would hold no more.
+
+"If the pail holds two gallons, Susie." said Uncle Robert, "how many
+quarts are there in one gallon?"
+
+"Four." said Susie, counting on her fingers.
+
+[Illustration: Two gallons. One quart.]
+
+"Well," said Uncle Robert as they went back into the dining-room, "now
+we have found how many quarts there are in a gallon; how shall we find
+how many gallons two hundred and sixteen thousand cubic inches will
+make?"
+
+"If I knew how many cubic inches there are in one gallon," said Frank,
+"I could do it."
+
+"How shall we find out?" asked Uncle Robert.
+
+"We might measure a gallon," said Donald, "and then if we could empty it
+into a flat pan couldn't we measure that?"
+
+"We can try," said Uncle Robert, "if your mother has the pan."
+
+"You may use one of those tins I bake biscuit in," said Mrs. Leonard.
+
+"I'll get it," said Susie.
+
+They measured it and found it was eleven inches long, seven inches wide,
+and two inches deep. The gallon of water filled it one and one half
+time.
+
+"If it had been three inches deep," said Frank, "the water would have
+just filled it."
+
+"Well," said Uncle Robert, "can you find out how many inches there are
+in all?"
+
+It took some time and several suggestions from Uncle Robert, but at last
+they found it to be two hundred thirty-one cubic inches.
+
+"Now," said Uncle Robert, "can you find how many two hundred thirty-one
+cubic inches there are in two hundred and sixteen thousand cubic
+inches?"
+
+"I know how," said Frank, figuring rapidly.
+
+In a short time he found that two hundred and sixteen thousand cubic
+inches would make over nine hundred thirty-five gallons.
+
+"If you were going to water the garden with the new two-gallon pail,"
+said Uncle Robert, "how many times would you have to fill it?"
+
+"If we took two gallons at a time," said Frank, "it would be--wait a
+minute--it would be four hundred sixty-seven and one half."
+
+"My," said Donald, "it makes my arms ache to think of it."
+
+"I'm going to find out how much fell on the whole farm some time," said
+Frank, "but I'm just tired out now."
+
+"Where does all the rain come from?" asked Susie. "I don't see how so
+much water can stay in the clouds."
+
+"It doesn't," said Donald, laughing. "That's why it rains."
+
+"But where does it all go to?" asked Uncle Robert.
+
+"Oh," said Susie, "it just goes into the ground."
+
+"Some of it runs off into the river," said Donald. "That's what makes it
+rise when it rains hard."
+
+"I wonder if it has risen much to-day?" said Frank.
+
+"We might put on our rubber boots and walk down and see," said Uncle
+Robert. "It is clearing off finely."
+
+"It is almost supper time now," said Mrs. Leonard. "If you'll wait I'll
+help Jane get it ready, and then you can go as soon as it is over."
+
+So they waited, and by the time they started the sun was shining
+brightly. It would be a whole hour before it would set.
+
+
+
+
+CHAPTER XIV.
+
+THE WALK AFTER THE RAIN.
+
+
+The sky was clear and bright as if it had been washed by the rain. The
+trees took on a fresher green. The corn held up its tasseled heads as if
+conscious of the strength the clouds had given it. The birds, too,
+rejoiced as they flew from tree to tree, singing their sweetest songs.
+
+"How nice it is to get out after being in the house all day," said
+Susie, skipping along by Uncle Robert's side. "See that lovely blue sky.
+I wish I had a dress for my doll just that color."
+
+"And when we came out this morning," said Uncle Robert, "Donald thought
+the clouds looked as though they were solid and could never break away."
+
+"They're all gone now," said Donald. "I wonder where they went. Aren't
+the clouds lovely sometimes, uncle? I love to watch them when they look
+like great piles of snow."
+
+"Yes," replied Uncle Robert, "when I was a boy I used to lie for hours
+under an old apple tree and watch the clouds. I fancied they had very
+wonderful forms, sometimes giants and dragons and all kinds of animals."
+
+[Illustration: The clouds.]
+
+"You can see things in them," said Donald. "I often do."
+
+"What are clouds made of, uncle?" asked Susie. "I wish I could get close
+to one and see what it is like."
+
+"When people go up in balloons," said Donald, "they go through clouds
+sometimes."
+
+"Have you never been in a cloud?" asked Uncle Robert, smiling.
+
+"Oh, no," said Susie. "How could I? I've never been up in a balloon."
+
+"I know," was the reply, "but have you never seen anything near the
+ground that looked at all like a cloud?"
+
+"I don't remember," said Susie, shaking her head.
+
+"We've seen fogs along the river," said Frank. "They look a little like
+clouds. You know we see them almost every morning."
+
+"Oh, yes," exclaimed Donald. "Don't you remember that fog we had early
+last spring? Why, uncle, it was so thick we couldn't see the barn from
+the house."
+
+"And, uncle," said Susie, "I went out to the barn with father, and in a
+few minutes there were little drops of water on my hair, and all over my
+cloak."
+
+"Did it last all day?" asked Uncle Robert.
+
+"Oh, no," said Frank, "only for a little while in the morning. Then it
+went away and the sun came out."
+
+"How did it go away?" asked Uncle Robert.
+
+"Why," said Donald, "at first it began to get lighter, and we could see
+things plainer."
+
+"And then," chimed in Susie, "it looked as though the fog broke up into
+pieces that rolled up in the sky, and floated off just like clouds."
+
+[Illustration: The gully.]
+
+"But what is that we see over the bottom land yonder?"
+
+"It looks like fog," said Frank.
+
+"More like steam, I think," said Donald.
+
+"If it was up there against that blue sky instead of on the ground--"
+said Uncle Robert.
+
+"Then it would be a cloud," said Susie. "Why, I never thought of that."
+
+They had gone through the gate in front of the house, and were following
+the path that led down the slope to the spring.
+
+"See how the water has plowed through the ground," said Frank, pointing
+to a gully the rain had made in the path.
+
+"It took a good many rains to make that gully," said Donald.
+
+"There was a little creek here for a while," said Frank. "The water has
+all run off now, but it has spoiled the path."
+
+"Will the gully get deeper every time it rains?" asked Susie.
+
+"Of course," said Donald. "That's what makes it."
+
+"Why does the water run along the path?" asked Uncle Robert.
+
+"Because it is lower than the ground on each side," said Frank.
+
+"How deep do you think the water will dig into the path if we do not
+fill it up?" asked Uncle Robert.
+
+"Oh, way, way down. I suppose," said Donald.
+
+"But if grass grew on the path," said Frank, "the water wouldn't wear
+the ground away. We will have to fill it up with stones."
+
+"See these pebbles, uncle," said Susie. "How did they get here? They
+look just like those we saw on the island."
+
+"Do you remember what I told you about the bowlders on the island?"
+
+"Yes, you said the bowlders were made by ice," answered Susie. "Did the
+ice make these pebbles?"
+
+"Perhaps so, and perhaps the river made them and left them here."
+
+"What! that river away down there? How could it get up here?"
+
+"That river away down there once flowed right over this ground," said
+Uncle Robert. "This slope," pointing just above, "was its bank, and the
+ground under our feet its bed."
+
+"That must have been a hundred years ago," said Donald.
+
+"Yes, a great many hundred years ago. You see the work this bit of a
+stream has done in the path? Many rivers begin just this way. They are
+cutting and changing the earth all the time."
+
+They had now come to the spring nearly at the foot of the slope. On
+sultry summer days it was a cool, inviting spot. The low-spreading
+branches of a beautiful bur oak shaded the little stream where it gushed
+from the outcropping limestone.
+
+"Do you want a drink?" asked Susie, taking the tin dipper which always
+hung by the spring.
+
+"Thank you, dear. How cool it is! It makes me think of the old spring in
+the hayfield where I used to work when I was a boy."
+
+"The rain has not made the spring run any faster," said Donald.
+
+"Where does this water come from?" asked Uncle Robert.
+
+"From out of the ground," said Susie. "How does it get into the ground?"
+
+[Illustration: The spring.]
+
+"It's always there, isn't it?" said Susie. "The spring runs all the
+time. I fill my pail here every day in the summer."
+
+"Yes, don't you remember when the wells all dried up last summer," said
+Frank, "that the spring was all right?"
+
+"Well, then, where has the water gone that fell to-day?" asked Uncle
+Robert.
+
+"Most of it has run off into the creek and river," said Donald. "It would
+look just like a lake if it was an inch and a half deep all over
+the ground."
+
+"Some of it has soaked into the ground," said Frank.
+
+"How deep down into the ground?" asked Uncle Robert.
+
+"Down to China," laughed Donald.
+
+"How deep do you have to dig to find water--to China?"
+
+"Our wells are about thirty feet deep," said Frank. "In a dry time
+there's no water in them."
+
+"How is it when you have a long wet spell?"
+
+"They are more than half full then."
+
+"Have both wells the same depth?"
+
+"I think so."
+
+"Where does the water in the wells come from?"
+
+"It is the rain that has soaked into the ground," said Frank.
+
+"How far down does it go?"
+
+"It must go down till it finds some hard clay or rock that stops it,"
+said Frank.
+
+"What does it do then?"
+
+"Then," said Frank slowly, "it must go along on top of the rock or
+clay."
+
+"When does it come out of the ground?"
+
+"Oh, I see! The rain goes down until it comes to that lime rock. Then it
+goes along the rock, and comes out there," said Donald, pointing to the
+spring.
+
+"Does it always?" asked Frank. "I have read of very deep wells that are
+bored down into the ground more than a thousand feet, and when the augur
+strikes water the water comes right up to the top of the ground."
+
+"You are talking about artesian wells," said Uncle Robert.
+
+"Yes, that is the name."
+
+[Illustration: Section of hillside.]
+
+They had left the spring and were walking down toward the mouth of the
+creek. The rain had swollen the little stream, and the water was dark
+with dirt.
+
+"See how muddy the water is," said Susie.
+
+"The creek must bring down a lot of earth," said Frank.
+
+"There are Joe and Dick Davis," said Donald, pointing across the river.
+"I wonder what they are doing? I'm going to see."
+
+Donald ran along to the mouth of the creek, which he reached as the
+Davis boys began to scramble down the steep bank to the edge of the
+river.
+
+"Hello there!" called Donald. "What are you fellows doing?"
+
+"Sticking in the mud," replied Joe Davis, holding up first one foot and
+then the other, heavy with the stiff clay that hung to it.
+
+"Why don't they go around by the path?" said Susie, coming up with Frank
+and Uncle Robert.
+
+"They'll always take the short cut if there is one," laughed Frank.
+"Come along over here!" he shouted.
+
+"All right," sang out Dick, scraping the mud from his shoes.
+
+An eddy in the stream just above the steep bank made a quiet place in
+the current. Here their boat was moored. As they pushed out from the
+shore they were swept down the stream, but a few strong pulls carried
+them beyond the swiftest part of the current, and then they easily rowed
+back to the landing at the mouth of the creek, where the Leonards were
+waiting for them.
+
+"I wish our bank was low like this," said Joe as he leaped from the
+boat. "We have to go so far downstream before we find a low bank on our
+side."
+
+"I should think you'd rather walk a mile," said Susie, looking at Joe's
+shoes, "than come down that bank when it's so muddy."
+
+"Humph! we don't mind a little mud," said Dick, wiping his feet on the
+grass.
+
+"You've brought some of your land over to us, I see," laughed Uncle
+Robert. "Mr. Leonard will be obliged to you. He is always glad when the
+soil is left on his side."
+
+"I don't see why it is," said Joe, "that our land is being cut away all
+the time and yours is getting bigger. It isn't fair."
+
+"We can't help it, Joe," said Susie. "It's the river that does it. You
+ask Uncle Robert. He'll tell you all about it."
+
+"I can tell you how it is," said Donald. "You know how strong the
+current is over on your side? Well, that's the reason your land is
+washed away. The water flows slower here, so it drops all the stuff it
+brings with it on our side. See?"
+
+"My!" said Dick, with a mischievous twinkle in his eyes, "doesn't he
+know a lot!"
+
+"Well, it's so," declared Donald, giving his head a nod. "You can see it
+yourself if you keep your eyes open."
+
+"My eyes are always open," said Dick, "but that doesn't keep our land."
+
+"You ought to have a creek," said Frank, "if you want your land to grow.
+Just look, uncle, what a lot of dirt has been left here."
+
+"It makes quite a delta, doesn't it?" replied Uncle Robert.
+
+"Sure enough," said Donald. "You remember the day of our picnic we were
+going to see if there was one here, and we forgot it."
+
+"Now you see where some of the dirt or silt that is brought down by the
+creek goes," said Uncle Robert. "And all this must have been left here
+since the flood in the spring. Frank is right. The creek is really
+building land all the time."
+
+"Most of the dirt or--what did you call it--silt goes down the river,
+doesn't it?" asked Frank.
+
+"Our land goes down the river," said Joe; "I've seen it."
+
+"And the river is building land for us," said Donald.
+
+"Yes," said Uncle Robert, "the river works all the time, tearing down in
+some places and building up in others. The clouds give us rain, the rain
+goes down into the ground, and then comes out and runs into the streams,
+and then--"
+
+"Into the ocean," said Frank.
+
+"And then--"
+
+No one spoke.
+
+"And then it rises up from the ocean and comes back again in clouds."
+
+"Did those clouds we had this morning come all the way from the ocean?"
+asked Joe. "I don't see how they could come so far?"
+
+"The clouds have swift wings to carry them," replied Uncle Robert. "They
+travel very far without tiring."
+
+"The wind brings the clouds, doesn't it, uncle?" asked Susie.
+
+"Yes, they come on the wings of the wind."
+
+"Oh," said Joe, "I see."
+
+"There's father blowing the horn," said Dick. "We must go."
+
+"Come again," said Uncle Robert and the children together.
+
+"I wish we could hear more about the river," said Joe to Frank as he
+helped them push off the boat.
+
+"Come over again any day," said Frank. "Uncle Robert will tell you all
+about it."
+
+"I wish he was my uncle, too," said Dick as they pulled out into the
+stream. "He isn't a bit stuck up and he knows a lot."
+
+
+
+
+CHAPTER XV.
+
+THE BIG BOOK.
+
+
+"Please tell us another story from the Big Book," begged Susie as the
+family were all seated on the piazza one beautiful summer evening.
+
+The great full moon, like a ball of molten iron, was rising in the east.
+It plowed a silver path across the river. Fireflies glimmered and
+sparkled in the dusky shadows of the meadow and in and out of the garden
+shrubs. The merry chirping of the crickets and the low hum of insect
+voices filled the air. Down by the creek the whip-poor-will told his one
+story over and over.
+
+"A story from the Big Book!" repeated Uncle Robert. "There are so many
+and they are all so wonderful. Ever since man was created he has read
+stories in the earth, water, and sky, and in all living things.
+Everything he has found in Nature helps him to live and grow wiser and
+better. We could never understand printed books unless we studied the
+Big Book. 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 books.
+The true desire to read these books springs from our love and study of
+Nature.
+
+"It was written for many years that the sun moved around the earth. But
+Copernicus studied the sun, earth, and stars anew, and he showed that
+the printed books were wrong by proving that the earth moved around the
+sun. Galileo read the same story through the telescope that he made.
+
+"Steam had always been a very common thing. Hot vapor had risen from
+heated water ever since fire was discovered, but the real story of steam
+had not been read until Watt sat long hours by a boiling teakettle. Then
+came the locomotive, the railroad, and mighty engines driving wheels
+that work for man."
+
+"Wasn't that a good story to read from the Big Book!" said Frank.
+
+"Lightning had flashed and thunder rolled throughout the ages. Men
+feared, wondered, and worshiped that mighty hidden power. Franklin
+looked straight at the forked lightning and asked, 'What are you?' The
+answer came in the telegraph that is fast making the nations of the
+earth one great family. Bell listened long and carefully to sounds, and
+now I can talk from New York to my friends in Chicago.
+
+"Are not these stories from the Big Book as wonderful as miracles? These
+are only a few of the many stories that have been read. Countless more
+will be read when children really open their eyes to the 'law of the
+Lord that converteth the soul.' Great men and great minds have road
+Nature's revelation in the past, 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 air. The Creator is
+writing the Big Book all the time for us--His children. Should we not
+read what He says there?"
+
+The children did not understand all that Uncle Robert said, yet they
+loved to listen.
+
+"We have found that our farm is a very interesting page of the Book,"
+said Mrs. Leonard.
+
+"Yes, that is the precious thing about it all.
+
+ "Whether we look, or whether we listen,
+ We hear life murmur or see it glisten."
+
+All eyes were gazing at the moon as it seemed to rise above the trees.
+The great face of the man in the moon became distinct as he looked down
+upon the rolling earth.
+
+"A beautiful and wonderful world," continued Uncle Robert, "but probably
+not a bit more wonderful than the countless worlds we see up there.
+
+"Just think! we are on a great round ball, and it is moving on its axis
+from west to east toward the moon. The moon, you know, does not really
+move over our heads as it seems to do. The round earth rolls upon its
+axis, and that makes the moon seem to rise higher and higher, and then
+sink away below the western horizon."
+
+"To-morrow night it will come up in the east a little later," said
+Frank.
+
+"Round and round we go upon our ball of earth. The sun seems to rise and
+set just as the moon does, but it is the world itself that makes the sun
+and moon seem to rise and set," said Uncle Robert.
+
+"What is our earth made of?" asked Donald.
+
+"Just what you see before you," answered Uncle Robert. "Under our feet
+we have the ground, the soil, gravel, sand, and loam, which is made
+of--"
+
+"Ground-up rock," said Frank.
+
+"And underneath the soil there is--"
+
+"The solid rock," said Frank.
+
+"And underneath that?" asked Mr. Leonard.
+
+"We do not know, but it is quite certain the solid earth is made of
+ground-up rock and rock that may be ground. The mills are all at work,
+grinding all the time."
+
+"The mills!" said Susie. "Where are the mills?"
+
+"I know one," said Donald. "The river is a great mill. Don't you
+remember about the pebbles?"
+
+"And the glaciers are mills, too," said Frank.
+
+[Illustration: Glaciers on the Coast of Norway]
+
+"Yes, the rivers, the ice rivers or glaciers, the wind, the frost, heat
+and cold, all grind masses of rock into bowlders, pebbles, and sand."
+
+"The rock has been ground so long I should think there would be nothing
+left but soil," said Frank.
+
+"You saw the limestone down by the spring?" asked Uncle Robert.
+
+"Yes," the children said together.
+
+"That limestone was once soft mud spread out upon the bottom of the
+ocean in shallow water."
+
+"How do you know that is so, uncle?" questioned Frank.
+
+[Illustration: Fossil fish.]
+
+"There are many proofs, but the best proof is that in the limestone are
+found shells of animals that live in the sea," said Uncle Robert.
+
+"Fossils," said Mrs. Leonard.
+
+"Yes, fossils. They are the remains of plants and animals that lived a
+very long time ago. Many rocks are almost entirely made of fossils. Fish
+and shells also have been covered with soft clay and left their
+imprints. Great beasts have walked in the mud, and we now find their
+footprints in the hard stone. Coral--you have seen coral?--is often found
+in limestone. It is made of the shells of little animals, called the
+polyp, which live in the sea."
+
+[Illustration: Coral]
+
+"So you see that the firm ground under foot is made of rock, some of
+which has been ground up over and over again. But there is something
+else besides rock that makes the world"
+
+"Water," said Donald promptly as he looked down upon the river.
+
+"Yes, the water is just as much a part of our world as the solid rock
+and the soil. There is water in the soil and in the solid rock, too. It
+comes out to us in----"
+
+"Springs," said Donald.
+
+"Water fills hollows in the earth----"
+
+"Ponds and lakes," said Frank.
+
+"Water runs down the slopes--"
+
+"Streams," said Frank.
+
+"Rivers," said Donald.
+
+"There is water in the air--mist, fogs, and clouds--and there is much
+water in the air which we can not see."
+
+"Vapor?" asked Frank.
+
+"Sometimes water is so thin we can not see it, and again it is so thick
+and hard that we may walk over it."
+
+"Ice," said Susie.
+
+"Tiny bits of vapor come together until they become so heavy that they
+fall to the ground."
+
+"Raindrops," said Donald.
+
+"Water is sometimes frozen in the clouds in beautiful white crystals,
+and then they sail down to the earth."
+
+"Snowflakes," said Susie.
+
+"Sometimes drops start from the clouds and go through very cold air. The
+cold air freezes them quickly, and then they rattle on the roof and dash
+on the ground. They cut the corn leaves and destroy the crops."
+
+"Hailstones," said Donald.
+
+"Oh," said Susie, "I saw a hailstone once as big as an egg."
+
+"The lakes are hollows in the ground filled with water. There are many
+small hollows, and some big ones, but there is one so great that we may
+call it immense. It is the largest hollow in the world--so large that it
+occupies three-fourths of the earth's surface."
+
+[Illustration: Ocean islands]
+
+"The ocean," said Frank.
+
+"Yes, the ocean is only a great big hollow filled with water."
+
+"How deep is the ocean?" asked Frank.
+
+"Very deep in some places--deeper than the height of the highest
+mountains. In others it is very shallow. In some places bits and masses
+of land rise out of the ocean."
+
+"Islands?" asked Donald.
+
+"Four great masses of land rise above the ocean level. These immense
+rock masses are called--"
+
+"Continents," said Frank.
+
+"Yes," said Uncle Robert. "We live on one of them."
+
+"The continent of North America," said Donald.
+
+"Our island rises right out of the river," said Susie.
+
+"Rock and water make only a part of our world. We live on the firm
+earth. But we live in something. Indeed, we live at the bottom of a
+great, deep ocean, deeper than the water ocean, and broader than the
+rock and water surface taken all together."
+
+"We live at the bottom of an ocean!" said Donald in surprise.
+
+"Now you are joking, Uncle Robert," said Susie. "If we lived on the
+bottom of an ocean we should all drown."
+
+"Fish live in the ocean, and we live in an ocean, too--a very deep one,
+how deep no one really knows. It may be a hundred, or hundreds of miles
+deep. We see a part of the surface of the earth and of the water, but no
+one has ever seen the surface of the mighty ocean in which we live."
+
+Susie and Donald were puzzled. Frank's face lighted up as he said:
+
+"I think you mean the air, Uncle Robert."
+
+"You are right, Frank. The great ocean in which we live is the air, or,
+as it is called, the atmosphere. The atmosphere is just as much a part
+of our world as the rock and the water. The rock we may call solid, the
+water fluid, and the air gaseous. Solid, fluid, gas."
+
+"How do we know that the atmosphere is so deep?" asked Frank.
+
+"We do not know exactly, but there are ways of proving that it is very,
+very deep. When people began to study the atmosphere they thought it
+extended about fifty miles from the surface of the earth. Now they are
+sure that it is much deeper. We know that air has weight, like soil and
+water. It presses on us and everything else--"
+
+"Fifteen pounds to the square inch," said Donald.
+
+"We weigh the air with the---"
+
+"Barometer," said Susie.
+
+"It is heavier at the ocean level than it is on the tops of mountains.
+We are sure that the higher we go up---"
+
+"The less the air weighs," said Frank.
+
+"At the height of fifty miles it is thought to have little or no weight,
+and so people believed that was as far as it extended. But in time they
+discovered another way of measuring the atmosphere. You have seen
+falling stars, haven't you?" asked Uncle Robert.
+
+[Illustration: Meteors.]
+
+"Oh, yes," said the three children together.
+
+"I saw a star fall, so fast--just like a rocket. Then the light went
+out, and I wondered where it went," said Susie.
+
+"Falling stars are not stars at all, though they look like them. They
+are pieces of rock that break off from other worlds and whiz through
+space."
+
+"Oh!" said Susie.
+
+"Outside of our atmosphere there may be nothing for these masses of rock
+to strike against, but just as soon as they come into the air, it tries
+to stop them. The air is not strong enough to stop them, but it grinds
+them up."
+
+"Grinds them up!" exclaimed Donald. "Isn't that wonderful? But, uncle,
+what makes them look just like fire?"
+
+"If you put an axe or scythe on a dry grindstone and turn the crank,
+what do you see?"
+
+"Sparks of fire," said Frank.
+
+"Why do you put grease or oil upon the axles of your buggy?"
+
+"To keep them from becoming hot and dry," said Frank. "One time when
+father and I were on a train there was a hot box, and we had to stop to
+cool it."
+
+"The heat and the sparks of fire are caused by one body rubbing against
+another. The faster they move, the greater the heat. This rubbing is
+called friction."
+
+"There was a time," said Mr. Leonard, "when fires were started by
+rubbing two pieces of wood together. Some Indians do so now."
+
+"Then the great pieces of rock rub against the air when they whiz
+through it, and that makes the sparks?" asked Frank.
+
+"You are right. We can see the blaze of fire caused by the friction."
+
+"I should think the rocks would fall on us and kill us," said Donald.
+
+"Most of them are probably ground up into bits of dust before they reach
+the ground. Some of them, indeed, do strike the ground, and very large
+ones bury themselves deep in the earth. When we go to the Field Columbian
+Museum, in Chicago, we shall see these visitors from other worlds. They
+are called meteoric stones, or meteorites. When they are in the air we
+call them meteors."
+
+"I am going to watch the next one I see," said Susie.
+
+"They fly so fast that you hardly see them before they are gone," said
+Donald.
+
+"Men who study the heavens tell of the depth of the atmosphere by the
+angle the meteor makes in falling, but perhaps you can not understand
+that now. So you see, children, we live on the bottom of a great ocean
+of air, and that air, or atmosphere, is a part of our world--the outside
+part."
+
+"How plain it all is," said Mrs. Leonard, "when we think of it this
+way!"
+
+"Now we have the land and the water," said Uncle Robert.
+
+"And the atmosphere," put in Donald.
+
+"And they are all right here close to us. Here is the land with its
+hollows, and there," pointing to the river glistening in the moonlight,
+"is the water, and--"
+
+"You can't see the air," said Donald.
+
+"We can feel it, anyway," said Susie.
+
+"How large is the earth, uncle?" asked Frank.
+
+"Eight thousand miles through it and twenty-five thousand miles around
+it," answered Uncle Robert.
+
+"But, uncle, is it all solid rock for eight thousand miles?"
+
+"No one knows. The rocky outside of the ball is called the crust of the
+earth. Miners have dug down nearly four thousand feet, and makers of
+artesian wells have bored still farther. They always find rock."
+
+"I wonder how far four thousand feet would be," said Donald.
+
+"A little over three quarters of a mile," said Mr. Leonard.
+
+"The farther they go down into the crust of the earth, the warmer they
+find it. I have been down in a mine thirty-two hundred feet, and it was
+very hot. No one could have lived there if cool air had not been brought
+down from the surface.
+
+"Some people have thought that inside the crust of the earth the rock is
+all a molten mass, like melted iron. You have read about volcanoes, and
+of the lava that is thrown out of them?"
+
+"Does that come out of the inside of the earth?" asked Donald.
+
+[Illustration: Down in a Gold Mine]
+
+"It comes from somewhere in the earth. Some men give their whole lives to
+the study of these questions, but you know they can not see beneath the
+crust of the earth. It is thought by some that the weight of the crust
+would keep the center of the earth a solid mass. So you see there are
+still many questions unsettled. We know that the crust is moving up and
+down all the time."
+
+"Oh, I hope the land won't rise here!" said Susie.
+
+"You wouldn't know it, Susie, if it did," said Uncle Robert, laughing.
+
+"Unless there was an earthquake," said Frank.
+
+"Or a volcano," said Donald. "I'd like to see one."
+
+"I would like to see the ocean," said Frank. "It must be grand to stand
+on the shore and look way off and not see anything but water."
+
+"It is a grand sight, Frank. I have sat on the beach many a time and
+watched the waves roll in, and thought of the wonderful work the ocean
+is doing. You know it is the great reservoir that supplies all the land
+with water."
+
+[Illustration: View of the Ocean]
+
+"The heat of the sun lifts the water up, or evaporates it. The vapor
+that makes the clouds rises into the air. The winds blow the vapor many
+long miles, and some of the clouds come right over our heads. The cold
+air draws the little bits of vapor together and makes the clouds heavy,
+and down they fall upon the earth as drops of rain.
+
+"Some of the rain runs directly into the streams. Some of the rain water
+sinks down into the earth; in the gravel it sinks fast; in the sand it
+sinks slower; and in the loam, clay, and rock it sinks very slowly
+indeed. The water in the ground dissolves the rock or the loose earth
+into little particles so fine that the tiny roots, or root hairs, drink
+them up, and so the rock furnishes a part of the nourishment, or food,
+of plants.
+
+"Without the water that the clouds bring no plant could grow. It gives
+life and growth to everything that lives, and then sinks deep into the
+earth. It comes out of the ground again in springs, and flows away in
+rivulets, brooks, creeks, and rivers--away, and away, back to the ocean
+again.
+
+"On its way to the ocean it wears down the land, carries silt from place
+to place, spreads it out on beaches, sand bars, bottom lands, deltas,
+and on the bottom of shallow places in the ocean."
+
+"Isn't it strange how everything changes, and how all the changes help
+us?" said Frank thoughtfully.
+
+"Yes, Frank, it is wonderful how the Creator of all things is constantly
+moving earth, air, and water, and, as you say, making all these changes
+to help man."
+
+"It is the Big Book that tells us of this marvelous world of ours and of
+other worlds as well. It lies open before us for us to read every day.
+God has created and is still creating our home, the dwelling place of
+His children. We must study Him, my dear children, in all He has made.
+We must learn of His works in order to use everything to make man
+happier, better, and more useful."
+
+Mr. Leonard, who had been listening very attentively to the story, said,
+as his face lighted with a happy smile:
+
+"I never thought of it all in that way before. Every day, in all our
+work on the farm and in the house--indeed, wherever we may be--we should
+learn new and beautiful revelations from our Heavenly Father; how much
+He is constantly giving us, and how thankful we should be."
+
+The moon had risen to its full glory over the earth. The waters of the
+river glistened. The trees, cornfields, and meadows were peaceful and
+grand, as though they, too, felt the power of the glorious light.
+
+Susie put her brown arms around her mother's neck and kissed her
+good-night.
+
+"Oh, how I love the Big Book!" she said.
+
+"I wish I could read it as all those great men have read it," said
+Frank.
+
+"So do I," said Donald.
+
+"'Day unto day uttereth speech, and night unto night sheweth
+knowledge,'" mused the mother as her loved ones went to bed with sweet
+thoughts of a beautiful world and a loving God.

+Project Gutenberg eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the US
+unless a copyright notice is included. Thus, we usually do not
+keep eBooks in compliance with any particular paper edition.
+
+We are now trying to release all our eBooks one year in advance
+of the official release dates, leaving time for better editing.
+Please be encouraged to tell us about any error or corrections,
+even years after the official publication date.
+
+Please note neither this listing nor its contents are final til
+midnight of the last day of the month of any such announcement.
+The official release date of all Project Gutenberg eBooks is at
+Midnight, Central Time, of the last day of the stated month. A
+preliminary version may often be posted for suggestion, comment
+and editing by those who wish to do so.
+
+Most people start at our Web sites at:
+https://gutenberg.org or
+http://promo.net/pg
+
+These Web sites include award-winning information about Project
+Gutenberg, including how to donate, how to help produce our new
+eBooks, and how to subscribe to our email newsletter (free!).
+
+
+Those of you who want to download any eBook before announcement
+can get to them as follows, and just download by date. This is
+also a good way to get them instantly upon announcement, as the
+indexes our cataloguers produce obviously take a while after an
+announcement goes out in the Project Gutenberg Newsletter.

+
+We produce about two million dollars for each hour we work. The
+time it takes us, a rather conservative estimate, is fifty hours
+to get any eBook selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. Our
+projected audience is one hundred million readers. If the value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour in 2002 as we release over 100 new text
+files per month: 1240 more eBooks in 2001 for a total of 4000+
+We are already on our way to trying for 2000 more eBooks in 2002
+If they reach just 1-2% of the world's population then the total
+will reach over half a trillion eBooks given away by year's end.
+
+The Goal of Project Gutenberg is to Give Away 1 Trillion eBooks!
+This is ten thousand titles each to one hundred million readers,
+which is only about 4% of the present number of computer users.
