Naturally many suggestions as +to changes, additions, and other improvements have reached its authors. +Naturally, too, the authors have busied themselves in devising methods +to add to the effectiveness of the book. Some additions have been made +almost every year since the book was published. To embody all these +changes and helpful suggestions into a strictly unified volume; to add +some further topics and sections; to bring all farm practices up to the +ideals of to-day; to include the most recent teaching of scientific +investigators--these were the objects sought in the thorough revision +which has just been given the book. The authors hope and think that the +remaking of the book has added to its usefulness and attractiveness. + +They believe now, as they believed before, that there is no line of +separation between the science of agriculture and the practical art of +agriculture. They are assured by the success of this book that +agriculture is eminently a teachable subject. They see no difference +between teaching the child the fundamental principles of farming and +teaching the same child the fundamental truths of arithmetic, geography, +or grammar. They hold that a youth should be trained for the farm just +as carefully as he is trained for any other occupation, and that it is +unreasonable to expect him to succeed without training. + +If they are right in these views, the training must begin in the public +schools. This is true for two reasons: + +1. It is universally admitted that aptitudes are developed, tastes +acquired, and life habits formed during the years that a child is in the +public school. Hence, during these important years every child intended +for the farm should be taught to know and love nature, should be led to +form habits of observation, and should be required to begin a study of +those great laws upon which agriculture is based. A training like this +goes far toward making his life-work profitable and delightful. + +2. Most boys and girls reared on a farm get no educational training +except that given in the public schools. If, then, the truths that +unlock the doors of nature are not taught in the public schools, nature +and nature's laws will always be hid in night to a majority of our +bread-winners. They must still in ignorance and hopeless drudgery tear +their bread from a reluctant soil. + +The authors return hearty thanks to Professor Thomas F. Hunt, University +of California; Professor Augustine D. Selby, Ohio Experiment Station; +Professor W. F. Massey, horticulturist and agricultural writer; and +Professor Franklin Sherman, Jr., State Entomologist of North Carolina, +for aid in proofreading and in the preparation of some of the material. + + CONTENTS + + CHAPTER I.

LIFE IN THE COUNTRY 330 + + + APPENDIX 339 + + + GLOSSARY 342 + + + INDEX 351 + + + + +TO THE TEACHER + + +Teachers sometimes shrink from undertaking the teaching of a simple +textbook on agriculture because they are not familiar with all the +processes of farming. By the same reasoning they might hesitate to teach +arithmetic because they do not know calculus or to teach a primary +history of the United States because they are not versed in all history. +The art of farming is based on the sciences dealing with the growth of +plants and animals. This book presents in a simple way these fundamental +scientific truths and suggests some practices drawn from them. Hence, +even though many teachers may not have plowed or sowed or harvested, +such teachers need not be embarrassed in mastering and heartily +instructing a class in nature's primary laws. + +If teachers realize how much the efficiency, comfort, and happiness of +their pupils will be increased throughout their lives from being taught +to coöperate with nature and to take advantage of her wonderful laws, +they will eagerly begin this study. They will find also that their +pupils will be actively interested in these studies bearing on their +daily lives, and this interest will be carried over to other subjects. +Whenever you can, take the pupils into the field, the garden, the +orchard, and the dairy. Teach them to make experiments and to learn by +the use of their own eyes and brains. They will, if properly led, +astonish you by their efforts and growth. + +You will find in the practical exercises many suggestions as to +experiments that you can make with your class or with individual +members. Do not neglect this first-hand teaching. It will be a delight +to your pupils. In many cases it will be best to finish the experiments +or observational work first, and later turn to the text to amplify the +pupil's knowledge. + +Although the book is arranged in logical order, the teacher ought to +feel free to teach any topic in the season best suited to its study. +Omit any chapter or section that does not bear on your crops or does not +deal with conditions in your state. + +The United States government and the different state experiment stations +publish hundreds of bulletins on agricultural subjects. These are sent +without cost, on application. It will be very helpful to get such of +these bulletins as bear on the different sections of the book. These +will be valuable additions to your school library. The authors would +like to give a list of these bulletins bearing on each chapter, but it +would soon be out of date, for the bulletins get out of print and are +supplanted by newer ones. However, the United States Department of +Agriculture prints a monthly list of its publications, and each state +experiment station keeps a list of its bulletins. A note to the +Secretary of Agriculture, Washington, D.C., or to your own state +experiment station will promptly bring you these lists, and from them +you can select what you need for your school. + + + + +AGRICULTURE FOR BEGINNERS + +CHAPTER I + +THE SOIL + + +SECTION I. ORIGIN OF THE SOIL + +The word _soil_ occurs many times in this little book. In agriculture +this word is used to describe the thin layer of surface earth that, like +some great blanket, is tucked around the wrinkled and age-beaten form of +our globe. The harder and colder earth under this surface layer is +called the _subsoil_. It should be noted, however, that in waterless and +sun-dried regions there seems little difference between the soil and the +subsoil. + +Plants, insects, birds, beasts, men,--all alike are fed on what grows in +this thin layer of soil. If some wild flood in sudden wrath could sweep +into the ocean this earth-wrapping soil, food would soon become as +scarce as it was in Samaria when mothers ate their sons. The face of the +earth as we now see it, daintily robed in grass, or uplifting waving +acres of corn, or even naked, water-scarred, and disfigured by man's +neglect, is very different from what it was in its earliest days. How +was it then? How was the soil formed? + +Learned men think that at first the surface of the earth was solid rock. +How was this rock changed into workable soil? Occasionally a curious boy +picks up a rotten stone, squeezes it, and finds his hands filled with +dirt, or soil. Now, just as the boy crumbled with his fingers this +single stone, the great forces of nature with boundless patience +crumbled, or, as it is called, disintegrated, the early rock mass. The +simple but giant-strong agents that beat the rocks into powder with a +clublike force a millionfold more powerful than the club force of +Hercules were chiefly (1) heat and cold; (2) water, frost, and ice; (3) +a very low form of vegetable life; and (4) tiny animals--if such minute +bodies can be called animals. In some cases these forces acted singly; +in others, all acted together to rend and crumble the unbroken stretch +of rock. Let us glance at some of the methods used by these skilled +soil-makers. + +Heat and cold are working partners. You already know that most hot +bodies shrink, or contract, on cooling. The early rocks were hot. As the +outside shell of rock cooled from exposure to air and moisture it +contracted. This shrinkage of the rigid rim of course broke many of the +rocks, and here and there left cracks, or fissures. In these fissures +water collected and froze. As freezing water expands with irresistible +power, the expansion still further broke the rocks to pieces. The +smaller pieces again, in the same way, were acted on by frost and ice +and again crumbled. This process is still a means of soil-formation. + +Running water was another giant soil-former. If you would understand its +action, observe some usually sparkling stream just after a washing rain. +The clear waters are discolored by mud washed in from the surrounding +hills. As though disliking their muddy burden, the waters strive to +throw it off. Here, as low banks offer chance, they run out into +shallows and drop some of it. Here, as they pass a quiet pool, they +deposit more. At last they reach the still water at the mouth of the +stream, and there they leave behind the last of their mud load, and +often form of it little three-sided islands called _deltas_. In the same +way mighty rivers like the Amazon, the Mississippi, and the Hudson, when +they are swollen by rain, bear great quantities of soil in their sweep +to the seas. Some of the soil they scatter over the lowlands as they +whirl seaward; the rest they deposit in deltas at their mouths. It is +estimated that the Mississippi carries to the ocean each year enough +soil to cover a square mile of surface to a depth of two hundred and +sixty-eight feet. + +[Illustration: FIG. 1. ROCK MARKED BY THE SCRAPING OF A GLACIER OVER IT] + +The early brooks and rivers, instead of bearing mud, ran oceanward +either bearing ground stone that they themselves had worn from the rocks +by ceaseless fretting, or bearing stones that other forces had already +dislodged. The large pieces were whirled from side to side and beaten +against one another or against bedrock until they were ground into +smaller and smaller pieces. The rivers distributed this rock soil just +as the later rivers distribute muddy soil. For ages the moving waters +ground against the rocks. Vast were the waters; vast the number of +years; vast the results. + +Glaciers were another soil-producing agent. Glaciers are streams "frozen +and moving slowly but irresistibly onwards, down well-defined valleys, +grinding and pulverizing the rock masses detached by the force and +weight of their attack." Where and how were these glaciers formed? + +Once a great part of upper North America was a vast sheet of ice. +Whatever moisture fell from the sky fell as snow. No one knows what made +this long winter of snow, but we do know that snows piled on snows until +mountains of white were built up. The lower snow was by the pressure of +that above it packed into ice masses. By and by some change of climate +caused the masses of ice to break up somewhat and to move south and +west. These moving masses, carrying rock and frozen earth, ground them +to powder. King thus describes the stately movement of these snow +mountains: "Beneath the bottom of this slowly moving sheet of ice, which +with more or less difficulty kept itself conformable with the face of +the land over which it was riding, the sharper outstanding points were +cut away and the deeper river cañons filled in. Desolate and rugged +rocky wastes were thrown down and spread over with rich soil." + +The joint action of air, moisture, and frost was still another agent of +soil-making. This action is called _weathering_. Whenever you have +noticed the outside stones of a spring-house, you have noticed that tiny +bits are crumbling from the face of the stones, and adding little by +little to the soil. This is a slow way of making additions to the soil. +It is estimated that it would take 728,000 years to wear away limestone +rock to a depth of thirty-nine inches. But when you recall the +countless years through which the weather has striven against the rocks, +you can readily understand that its never-wearying activity has added +immensely to the soil. + +In the rock soil formed in these various ways, and indeed on the rocks +themselves, tiny plants that live on food taken from the air began to +grow. They grew just as you now see mosses and lichens grow on the +surface of rocks. The decay of these plants added some fertility to the +newly formed soil. The life and death of each succeeding generation of +these lowly plants added to the soil matter accumulating on the rocks. +Slowly but unceasingly the soil increased in depth until higher +vegetable forms could flourish and add their dead bodies to it. This +vegetable addition to the soil is generally known as _humus_. + +[Illustration: FIG. 2. GROUND ROCK AT END OF A GLACIER] + +In due course of time low forms of animal life came to live on these +plants, and in turn by their work and their death to aid in making a +soil fit for the plowman. + +Thus with a deliberation that fills man with awe, the powerful forces of +nature splintered the rocks, crumbled them, filled them with plant food, +and turned their flinty grains into a soft, snug home for vegetable +life. + + +SECTION II. TILLAGE OF THE SOIL + +A good many years ago a man by the name of Jethro Tull lived in England. +He was a farmer and a most successful man in every way. He first taught +the English people and the world the value of thorough tillage of the +soil. Before and during his time farmers did not till the soil very +intelligently. They simply prepared the seed-bed in a careless manner, +as a great many farmers do to-day, and when the crops were gathered the +yields were not large. + +Jethro Tull centered attention on the important fact that careful and +thorough tillage increases the available plant food in the soil. He did +not know why his crops were better when the ground was frequently and +thoroughly tilled, but he knew that such tillage did increase his yield. +He explained the fact by saying, "Tillage is manure." We have since +learned the reason for the truth that Tull taught, and, while his +explanation was incorrect, the practice that he was following was +excellent. The stirring of the soil enables the air to circulate through +it freely, and permits a breaking down of the compounds that contain the +elements necessary to plant growth. + +You have seen how the air helps to crumble the stone and brick in old +buildings. It does the same with soil if permitted to circulate freely +through it. The agent of the air that chiefly performs this work is +called carbonic acid gas, and this gas is one of the greatest helpers +the farmer has in carrying on his work. We must not forget that in soil +preparation the air is just as important as any of the tools and +implements used in cultivation. + +[Illustration: FIG. 3. SLOPE TO WATER SHOWS SOIL WEATHERED FROM FACE +OF CLIFF] + +If the soil is fertile and if deep plowing has always been done, good +crops will result, other conditions being favorable. If, however, the +tillage is poor, scanty harvests will always result. For most soils a +two-horse plow is necessary to break up and pulverize the land. + +A shallow soil can always be improved by properly deepening it. The +principle of greatest importance in soil-preparation is the gradual +deepening of the soil in order that plant-roots may have more +comfortable homes. If the farmer has been accustomed to plow but four +inches deep, he should adjust the plow so as to turn five inches at the +next plowing, then six, and so on until the seed-bed is nine or ten +inches deep. This gradual deepening will not injure the soil but will +put it quickly in good condition. If to good tillage rotation of crops +be added, the soil will become more fertile with each succeeding year. + +[Illustration: FIG. 4. MIXED GRASSES GROWN FOR FORAGE] + +The plow, harrow, and roller are all necessary to good tillage and to a +proper preparation of the seed-bed. The soil must be made compact and +clods of all sizes must be crushed. Then the air circulates freely, and +paying crops are the rule and not the exception. + +Tillage does these things: it increases the plant-food supply, destroys +weeds, and influences the moisture content of the soil. + + + =EXERCISE= + + 1. What tools are used in tillage? + + 2. How should a poor and shallow soil be treated? + + 3. Why should a poor and shallow soil be well compacted before + sowing the crop? + + 4. Explain the value of a circulation of air in the soil. + + 5. What causes iron to rust? + + 6. Why is a two-horse turning-plow better than a one-horse plow? + + 7. Where will clods do the least harm--on top of the soil or below + the surface? + + 8. Do plant roots penetrate clods? + + 9. Are earthworms a benefit or an injury to the soil? + + 10. Name three things that tillage does. + + +SECTION III. THE MOISTURE OF THE SOIL + +Did any one ever explain to you how important water is to the soil, or +tell you why it is so important? Often, as you know, crops entirely fail +because there is not enough water in the soil for the plants to drink. +How necessary is it, then, that the soil be kept in the best possible +condition to catch and hold enough water to carry the plant through dry, +hot spells! Perhaps you are ready to ask, "How does the mouthless plant +drink its stored-up water?" + +The plant gets all its water through its roots. You have seen the tiny +threadlike roots of a plant spreading all about in fine soil; they are +down in the ground taking up plant food and water for the stalk and +leaves above. The water, carrying plant food with it, rises in a simple +but peculiar way through the roots and stems. + +The plants use the food for building new tissue, that is, for growth. +The water passes out through the leaves into the air. When the summers +are dry and hot and there is but little water in the soil, the leaves +shrink up. This is simply a method they have of keeping the water from +passing too rapidly off into the air. I am sure you have seen the corn +blades all shriveled on very hot days. This shrinkage is nature's way of +diminishing the current of water that is steadily passing through the +plant. + +A thrifty farmer will try to keep his soil in such good condition that +it will have a supply of water in it for growing crops when dry and hot +weather comes. He can do this by deep plowing, by subsoiling, by adding +any kind of decaying vegetable matter to the soil, and by growing crops +that can be tilled frequently. + +The soil is a great storehouse for moisture. After the clouds have +emptied their waters into this storehouse, the water of the soil comes +to the surface, where it is evaporated into the air. The water comes to +the surface in just the same way that oil rises in a lamp-wick. This +rising of the water is called _capillarity_. + +[Illustration: FIG. 5. AN ENLARGED VIEW OF A SECTION OF MOIST SOIL, +SHOWING AIR SPACES AND SOIL PARTICLES] + +It is necessary to understand what is meant by this big word. If into a +pan of water you dip a glass tube, the water inside the tube rises above +the level of the water in the pan. The smaller the tube the higher will +the water rise. The greater rise inside is perhaps due to the fact that +the glass attracts the particles of water more than the particles of +water attract one another. Now apply this principle to the soil. + +[Illustration: FIG. 6. THE RIGHT WAY TO PLOW] + +The soil particles have small spaces between them, and the spaces act +just as the tube does. When the water at the surface is carried away by +drying winds and warmth, the water deeper in the soil rises through +the soil spaces. In this way water is brought from its soil storehouse +as plants need it. + +[Illustration: FIG. 7. APPARATUS FOR TESTING THE HOLDING OF WATER BY +DIFFERENT SOILS] + +Of course when the underground water reaches the surface it evaporates. +If we want to keep it for our crops, we must prepare a trap to hold it. +Nature has shown us how this can be done. Pick up a plank as it lies on +the ground. Under the plank the soil is wet, while the soil not covered +by the plank is dry. Why? Capillarity brought the water to the surface, +and the plank, by keeping away wind and warmth, acted as a trap to hold +the moisture. Now of course a farmer cannot set a trap of planks over +his fields, but he can make a trap of dry earth, and that will do just +as well. + +When a crop like corn or cotton or potatoes is cultivated, the fine, +loose dirt stirred by the cultivating-plow will make a mulch that serves +to keep water in the soil in the same way that the plank kept moisture +under it. The mulch also helps to absorb the rains and prevents the +water from running off the surface. Frequent cultivation, then, is one +of the best possible ways of saving moisture. Hence the farmer who most +frequently stirs his soil in the growing season, and especially in +seasons of drought, reaps, other things being equal, a more abundant +harvest than if tillage were neglected. + + + =EXERCISE= + + 1. Why is the soil wet under a board or under straw? + + 2. Will a soil that is fine and compact produce better crops than + one that is loose and cloddy? Why? + + 3. Since the water which a plant uses comes through the roots, can + the morning dew afford any assistance? + + 4. Why are weeds objectionable in a growing crop? + + 5. Why does the farmer cultivate growing corn and cotton? + + +SECTION IV. HOW THE WATER RISES IN THE SOIL + +[Illustration: FIG. 8. USING LAMP-CHIMNEYS TO SHOW THE RISE OF WATER +IN SOIL] + +When the hot, dry days of summer come, the soil depends upon the +subsoil, or undersoil, for the moisture that it must furnish its growing +plants. The water was stored in the soil during the fall, winter, and +spring months when there was plenty of rain. If you dig down into the +soil when everything is dry and hot, you will soon reach a cool, moist +undersoil. The moisture increases as you dig deeper into the soil. + +Now the roots of plants go down into the soil for this moisture, because +they need the water to carry the plant food up into the stems and +leaves. + +You can see how the water rises in the soil by performing a simple +experiment. + + + =EXPERIMENT= + + Take a lamp-chimney and fill it with fine, dry dirt. The dirt from + a road or a field will do. Tie over the smaller end of the + lamp-chimney a piece of cloth or a pocket handkerchief, and place + this end in a shallow pan of water. If the soil in the lamp-chimney + is clay and well packed, the water will quickly rise to the top. + + By filling three or four lamp-chimneys with as many different + soils, the pupil will see that the water rises more slowly in some + than in others. + + Now take the water pan away, and the water in the lamp-chimneys + will gradually evaporate. Study for a few days the effect of + evaporation on the several soils. + + +SECTION V. DRAINING THE SOIL + +A wise man was once asked, "What is the most valuable improvement ever +made in agriculture?" He answered, "Drainage." Often soils unfit for +crop-production because they contain too much water are by drainage +rendered the most valuable of farming lands. + +Drainage benefits land in the following ways: + +1. It deepens the subsoil by removing unnecessary water from the spaces +between the soil particles. This admits air. Then the oxygen which is in +the air, by aiding decay, prepares plant food for vegetation. + +2. It makes the surface soil, or topsoil, deeper. It stands to reason +that the deeper the soil the more plant food becomes available for plant +use. + +3. It improves the texture of the soil. Wet soil is sticky. Drainage +makes this sticky soil crumble and fall apart. + +4. It prevents washing. + +5. It increases the porosity of soils and permits roots to go deeper +into the soil for food and moisture. + +6. It increases the warmth of the soil. + +7. It permits earlier working in spring and after rains. + +[Illustration: FIG. 9. LAYING A TILE DRAIN] + +8. It favors the growth of germs which change the unavailable nitrogen +of the soil into nitrates; that is, into the form of nitrogen most +useful to plants. + +9. It enables plants to resist drought better because the roots go into +the ground deeper early in the season. + +A soil that is hard and wet will not grow good crops. The +nitrogen-gathering crops will store the greatest quantity of nitrogen in +the soil when the soil is open to the free circulation of the air. +These valuable crops cannot do this when the soil is wet and cold. + +Sandy soils with sandy subsoils do not often need drainage; such soils +are naturally drained. With clay soils it is different. It is very +important to remove the stagnant water in them and to let the air in. + +When land has been properly drained the other steps in improvement are +easily taken. After soil has been dried and mellowed by proper drainage, +then commercial fertilizers, barnyard manure, cowpeas, and clover can +most readily do their great work of improving the texture of the soil +and of making it fitter for plant growth. + +[Illustration: FIG. 10. A TILE IN POSITION] + +=Tile Drains.= Tile drains are the best and cheapest that can be used. +It would not be too strong to say that draining by tiles is the most +perfect drainage. Thousands of practical tests in this country have +proved the superiority of tile draining for the following reasons: + +1. Good tile drains properly laid last for years and do not fill up. + +2. They furnish the cheapest possible means of removing too much water +from the soil. + +3. They are out of reach of all cultivating tools. + +4. Surface water in filtering through the tiles leaves its nutritious +elements for plant growth. + + + =EXPERIMENTS= + + =To show the Effect of Drainage.= Take two tomato cans and fill + both with the same kind of soil. Punch several holes in the bottom + of one to drain the soil above and to admit air circulation. Leave + the other unpunctured. Plant seeds of any kind in both cans and + keep in a warm place. Add every third day equal quantities of + water. Let seeds grow in both cans and observe the difference in + growth for two or three weeks. + + =To show the Effect of Air in Soils.= Take two tomato cans; fill + one with soil that is loose and warm, and the other with wet clay + or muck from a swampy field. Plant a few seeds of the same kind in + each and observe how much better the dry, warm, open soil is for + growing farm crops. + + +SECTION VI. IMPROVING THE SOIL + +We hear a great deal about the exhaustion or wearing out of the soil. +Many uncomfortable people are always declaring that our lands will no +longer produce profitable crops, and hence that farming will no longer +pay. + +Now it is true, unfortunately, that much land has been robbed of its +fertility, and, because this is true, we should be most deeply +interested in everything that leads to the improvement of our soils. + +When our country was first discovered and trees were growing everywhere, +we had virgin soils, or new soils that were rich and productive because +they were filled with vegetable matter and plant food. There are not +many virgin soils now because the trees have been cut from the best +lands, and these lands have been farmed so carelessly that the vegetable +matter and available plant food have been largely used up. Now that +fresh land is scarce it is very necessary to restore fertility to these +exhausted lands. What are some of the ways in which this can be done? + +[Illustration: FIG. 11. CLOVER IS A SOIL-IMPROVER] + +There are several things to be done in trying to reclaim worn-out land. +One of the first of these is to till the land well. Many of you may have +heard the story of the dying father who called his sons about him and +whispered feebly, "There is great treasure hidden in the garden." The +sons could hardly wait to bury their dead father before, thud, thud, +thud, their picks were going in the garden. Day after day they dug; they +dug deep; they dug wide. Not a foot of the crop-worn garden escaped the +probing of the pick as the sons feverishly searched for the expected +treasure. But no treasure was found. Their work seemed entirely useless. + +[Illustration: FIG. 12. INCREASING THE PRODUCTIVE POWER OF THE SOIL +Second crop of cowpeas on old, abandoned land] + +"Let us not lose every whit of our labor; let us plant this pick-scarred +garden," said the eldest. So the garden was planted. In the fall the +hitherto neglected garden yielded a harvest so bountiful, so unexpected, +that the meaning of their father's words dawned upon them. "Truly," they +said, "a treasure was hidden there. Let us seek it in all our fields." + +The story applies as well to-day as it did when it was first told. +Thorough culture of the soil, frequent and intelligent tillage--these +are the foundations of soil-restoration. + +Along with good tillage must go crop-rotation and good drainage. A +supply of organic matter will prevent heavy rains from washing the soil +and carrying away plant food. Drainage will aid good tillage in allowing +air to circulate between the soil particles and in arranging plant food +so that plants can use it. + +But we must add humus, or vegetable matter, to the soil. You remember +that the virgin soils contained a great deal of vegetable matter and +plant food, but by the continuous growing of crops like wheat, corn, and +cotton, and by constant shallow tillage, both humus and plant food have +been used up. Consequently much of our cultivated soil to-day is hard +and dead. + +There are three ways of adding humus and plant food to this lifeless +land: the first way is to apply barnyard manure (to adopt this method +means that livestock raising must be a part of all farming); the second +way is to adopt rotation of crops, and frequently to plow under crops +like clover and cowpeas; the third way is to apply commercial +fertilizers. + +To summarize: if we want to make our soil better year by year, we must +cultivate well, drain well, and in the most economical way add humus and +plant food. + + + =EXPERIMENT= + + Select a small area of ground at your home and divide it into four + sections, as shown in the following sketch: + + On Section _A_ apply barnyard manure; on Section _B_ apply + commercial fertilizers; on Section _C_ apply nothing, but till + well; on Section _D_ apply nothing, and till very poorly. + + _A_, _B_, and _C_ should all be thoroughly plowed and harrowed. + Then add barnyard manure to _A_, commercial fertilizers to _B_, and + harrow _A_, _B_, and _C_ at least four times until the soil is + mellow and fine. _D_ will most likely be cloddy, like many fields + that we often see. Now plant on each plat some crop like cotton, + corn, or wheat. When the plats are ready to harvest, measure the + yield of each and determine whether the increased yield of the best + plats has paid for the outlay for tillage and manure. The pupil + will be much interested in the results obtained from the first + crop. + + [Illustration: FIG. 13] + + Now follow a system of crop-rotation on the plats. Clover can + follow corn or cotton or wheat; and cowpeas, wheat. Then determine + the yield of each plat for the second crop. By following these + plats for several years, and increasing the number, the pupils will + learn many things of greatest value. + + + + +SECTION VII. MANURING THE SOIL + +In the early days of our history, when the soil was new and rich, we +were not compelled to use large amounts of manures and fertilizers. Yet +our histories speak of an Indian named Squanto who came into one of the +New England colonies and showed the first settlers how, by putting a +fish in each hill of corn, they could obtain larger yields. + +If people in those days, with new and fertile soils, could use manures +profitably, how much more ought we to use them in our time, when soils +have lost their virgin fertility, and when the plant food in the soil +has been exhausted by years and years of cropping! + +To sell year after year all the produce grown on land is a sure way to +ruin it. If, for example, the richest land is planted every year in +corn, and no stable or farmyard manure or other fertilizer returned to +the soil, the land so treated will of course soon become too poor to +grow any crop. If, on the other hand, clover or alfalfa or corn or +cotton-seed meal is fed to stock, and the manure from the stock returned +to the soil, the land will be kept rich. Hence those farmers who do not +sell such raw products as cotton, corn, wheat, oats, and clover, but who +market articles made from these raw products, find it easier to keep +their land fertile. For illustration: if instead of selling hay, farmers +feed it to sheep and sell meat and wool; if instead of selling cotton +seed, they feed its meal to cows, and sell milk and butter; if instead +of selling stover, they feed it to beef cattle, they get a good price +for products and in addition have all the manure needed to keep their +land productive and increase its value each year. + +[Illustration:FIG. 14. RELATION OF HUMUS TO GROWTH OF CORN +1, clay subsoil; 2, same, with fertilizer; 3, same, with humus] + +If we wish to keep up the fertility of our lands we should not allow +anything to be lost from our farms. All the manures, straw, roots, +stubble, healthy vines--in fact everything decomposable--should be +plowed under or used as a top-dressing. Especial care should be taken in +storing manure. It should be watchfully protected from sun and rain. If +a farmer has no shed under which to keep his manure, he should scatter +it on his fields as fast as it is made. + +[Illustration: FIG. 15. THE COTTON PLANT WITH AND WITHOUT FOOD +In left top pot, no plant food; in left bottom pot, plant food scanty; +in both right pots, all elements of plant food present] + +He should understand also that liquid manure is of more value than +solid, because that important plant food, nitrogen, is found almost +wholly in the liquid portion. Some of the phosphoric acid and +considerable amounts of the potash are also found in the liquid manure. +Hence economy requires that none of this escape either by leakage or by +fermentation. Sometimes one can detect the smell of ammonia in the +stable. This ammonia is formed by the decomposition of the liquid +manure, and its loss should be checked by sprinkling some floats, acid +phosphate, or muck over the stable floor. + +Many farmers find it desirable to buy fertilizers to use with the manure +made on the farm. In this case it is helpful to understand the +composition, source, and availability of the various substances +composing commercial fertilizers. The three most valuable things in +commercial fertilizers are nitrogen, potash, and phosphoric acid. + +The nitrogen is obtained from (1) nitrate of soda mined in Chile, (2) +ammonium sulphate, a by-product of the gas works, (3) dried blood and +other by-products of the slaughter-houses, and (4) cotton-seed meal. +Nitrate of soda is soluble in water and may therefore be washed away +before being used by plants. For this reason it should be applied in +small quantities and at intervals of a few weeks. + +Potash is obtained in Germany, where it is found in several forms. It is +put on the market as muriate of potash, sulphate of potash, kainite, +which contains salt as an impurity, and in other impure forms. Potash is +found also in _unleached_ wood ashes. + +Phosphoric acid is found in various rocks of Tennessee, Florida, and +South Carolina, and also to a large extent in bones. The rocks or bones +are usually treated with sulphuric acid. This treatment changes the +phosphoric acid into a form ready for plant use. + +These three kinds of plant food are ordinarily all that we need to +supply. In some cases, however, lime has to be added. Besides being a +plant food itself, lime helps most soils by improving the structure of +the grains; by sweetening the soil, thereby aiding the little living +germs called _bacteria_; by hastening the decay of organic matter; and +by setting free the potash that is locked up in the soil. + + + + +CHAPTER II + +THE SOIL AND THE PLANT + + +SECTION VIII. ROOTS + + +[Illustration: FIG. 16. ROOT-HAIRS ON A RADISH] + +You have perhaps observed the regularity of arrangement in the twigs and +branches of trees. Now pull up the roots of a plant, as, for example, +sheep sorrel, Jimson weed, or some other plant. Note the branching of +the roots. In these there is no such regularity as is seen in the twig. +Trace the rootlets to their finest tips. How small, slender, and +delicate they are! Still we do not see the finest of them, for in taking +the plant from the ground we tore the most delicate away. In order to +see the real construction of a root we must grow one so that we may +examine it uninjured. To do this, sprout some oats in a germinator or in +any box in which one glass side has been arranged and allow the oats to +grow till they are two or more inches high. Now examine the roots and +you will see very fine hairs, similar to those shown in the accompanying +figure, forming a fuzz over the surface of the roots near the tips. This +fuzz is made of small hairs standing so close together that there are +often as many as 38,200 on a single square inch. Fig. 17 shows how a +root looks when it has been cut crosswise into what is known as a cross +section. The figure is much increased in size. You can see how the +root-hairs extend from the root in every direction. Fig. 18 shows a +single root-hair very greatly enlarged, with particles of sand sticking +to it. + +[Illustration: FIG. 17. A SLICE OF A ROOT +Highly magnified] + +These hairs are the feeding-organs of the roots, and they are formed +only near the tips of the finest roots. You see that the large, coarse +roots that you are familiar with have nothing to do with _absorbing_ +plant food from the soil. They serve merely to _conduct_ the sap and +nourishment from the root-hairs to the tree. + +When you apply manure or other fertilizer to a tree, remember that it is +far better to supply the fertilizer to the roots that are at some +distance from the trunk, for such roots are the real feeders. The plant +food in the manure soaks into the soil and immediately reaches the +root-hairs. You can understand this better by studying the distribution +of the roots of an orchard tree, shown in Fig. 19. There you can see +that the fine tips are found at a long distance from the main trunk. + +[Illustration: FIG. 18. A ROOT-HAIR WITH PARTICLES OF SOIL STICKING +TO IT] + +You can now readily see why it is that plants usually wilt when they are +transplanted. The fine, delicate root-hairs are then broken off, and the +plant can but poorly keep up its food and water supply until new hairs +have been formed. While these are forming, water has been evaporating +from the leaves, and consequently the plant does not get enough moisture +and therefore droops. + +[Illustration: FIG. 19. DISTRIBUTION OF APPLE-TREE ROOTS] + +Would you not conclude that it is very poor farming to till deeply any +crop after the roots have extended between the rows far enough to be cut +by the plow or cultivator? In cultivating between corn rows, for +example, if you find that you are disturbing fine roots, you may be sure +that you are breaking off millions of root-hairs from each plant and +hence are doing harm rather than good. Fig. 20 shows how the roots from +one corn row intertangle with those of another. You see at a glance how +many of these roots would be destroyed by deep cultivation. Stirring +the upper inch of soil when the plants are well grown is sufficient +tillage and does no injury to the roots. + +[Illustration: FIG. 20. CORN ROOTS REACH FROM ROW TO ROW] + +A deep soil is much better than a shallow soil, as its depth makes it +just so much easier for the roots to seek deep food. Fig. 21 illustrates +well how far down into the soil the alfalfa roots go. + +[Illustration: FIG. 21 ALFALFA ROOT] + + + =EXERCISE= + + Dig up the roots of several cultivated plants and weeds and compare + them. Do you find some that are fine or fibrous? some fleshy like + the carrot? The dandelion is a good example of a tap-root. + Tap-roots are deep feeders. Examine very carefully the roots of a + medium-sized corn plant. Sift the dirt away gently so as to loosen + as few roots as possible. How do the roots compare in area with the + part above the ground? Try to trace a single root of the corn plant + from the stalk to its very tip. How long are the roots of mature + plants? Are they deep or shallow feeders? Germinate some oats or + beans in a glass-sided box, as suggested, and observe the + root-hairs. + + +SECTION IX. HOW THE PLANT FEEDS FROM THE SOIL + +Plants receive their nourishment from two sources--from the air and from +the soil. The soil food, or mineral food, dissolved in water, must reach +the plant through the root-hairs with which all plants are provided in +great numbers. Each of these hairs may be compared to a finger reaching +among the particles of earth for food and water. If we examine the +root-hairs ever so closely, we find no holes, or openings, in them. It +is evident, then, that no solid particles can enter the root-hairs, but +that all food must pass into the root in solution. + +An experiment just here will help us to understand how a root feeds. + +[Illustration: FIG. 22. EXPERIMENT TO SHOW HOW ROOTS TAKE UP FOOD] + + + =EXPERIMENT= + + Secure a narrow glass tube like the one in Fig. 22. If you cannot + get a tube, a narrow, straight lamp-chimney will, with a little + care, do nearly as well. From a bladder made soft by soaking, cut a + piece large enough to cover the end of the tube or chimney and to + hang over a little all around. Make the piece of bladder secure to + the end of the tube by wrapping tightly with a waxed thread, as at + B. Partly fill the tube with molasses (or it may be easier in case + you use a narrow tube to fill it before attaching the bladder). Put + the tube into a jar or bottle of water so placed that the level of + the molasses inside and the water outside will be the same. Fasten + the tube in this position and observe it frequently for three or + four hours. At the end of the time you should find that the + molasses in the tube has risen above the level of the liquid + outside. It may even overflow at the top. If you use the + lamp-chimney the rise will not be so clearly seen, since a greater + volume is required to fill the space in the chimney. This increase + in the contents of the tube is due to the entrance of water from + the outside. The water has passed through the thin bladder, or + membrane, and has come to occupy space in the tube. There is also a + passage the other way, but the molasses can pass through the + bladder membrane so slowly that the passage is scarcely noticeable. + There are no holes, or openings, in the membrane, but still there + is a free passage of liquids in both directions, although the more + heavily laden solution must move more slowly. + +A root-hair acts in much the same way as the tube in our experiment, +with the exception that it is so made as to allow certain substances to +pass in only one direction, that is, toward the inside. The outside of +the root-hair is bathed in solutions rich in nourishment. The +nourishment passes from the outside to the inside through the delicate +membrane of the root-hair. Thus does food enter the plant-root. From the +root-hairs, foods are carried to the inside of the root. + +From this you can see how important it is for a plant to have fine, +loose soil for its root-hairs; also how necessary is the water in the +soil, since the food can be used only when it is dissolved in water. + +This passage of liquids from one side of a membrane to another is called +_osmosis_. It has many uses in the plant kingdom. We say a root takes +nourishment by osmosis. + + +SECTION X. ROOT-TUBERCLES + +Tubercle is a big word, but you ought to know how to pronounce it and +what is meant by root-tubercles. We are going to tell you what a +root-tubercle is and something about its importance to agriculture. When +you have learned this, we are sure you will want to examine some plants +for yourself in order that you may see just what tubercles look like on +a real root. + +Root-tubercles do not form on all kinds of plants that farmers grow. +They are formed only on those kinds that botanists call _legumes_. The +clovers, cowpeas, vetches, soy beans, and alfalfa are all legumes. The +tubercles are little knotty, wart-like growths on the roots of the +plants just named. These tubercles are caused by tiny forms of life +called, as you perhaps already know, bacteria, or _germs_. + +[Illustration: FIG. 23. TUBERCLES ON CLOVER ROOTS +The specimen at the right was grown in soil inoculated with soil from an +old clover field. The one at the left was grown in soil not inoculated] + +Instead of living in nests in trees like birds or in the ground like +moles and worms, these tiny germs, less than one twenty-five thousandth +of an inch long, make their homes on the roots of legumes. Nestling +snugly together, they live, grow, and multiply in their sunless homes. +Through their activity the soil is enriched by the addition of much +nitrogen from the air. They are the good fairies of the farmer, and no +magician's wand ever blessed a land so much as these invisible folk +bless the land that they live in. + +Just as bees gather honey from the flowers and carry it to the hives, +where they prepare it for their own future use and for the use of +others, so do these root-tubercles gather nitrogen from the air and fix +it in their root homes, where it can be used by other crops. + +[Illustration: FIG. 24. SOY BEANS AND COWPEAS, TWO GREAT SOIL-IMPROVERS] + +In the earlier pages of this book you were told something about the food +of plants. One of the main elements of plant food, perhaps you remember, +is nitrogen. Just as soon as the roots of the leguminous plants begin to +push down into the soil, the bacteria, or germs that make the tubercles, +begin to build their homes on the roots, and in so doing they add +nitrogen to the soil. You now see the importance of growing such crops +as peas and clover on your land, for by their tubercles you can +constantly add plant food to the soil. Now this much-needed nitrogen is +the most costly part of the fertilizers that farmers buy every year. If +every farmer, then, would grow these tubercle-bearing crops, he would +rapidly add to the richness of his land and at the same time escape the +necessity of buying so much expensive fertilizer. + + + =EXPERIMENT= + + Take a spade or shovel and dig carefully around the roots of a + cowpea and a clover plant; loosen the earth thoroughly and then + pull the plants up, being careful not to break off any of the + roots. Now wash the roots, and after they become dry count the + nodules, or tubercles, on them. Observe the difference in size. How + are they arranged? Do all leguminous plants have equal numbers of + nodules? How do these nodules help the farmer? + + +SECTION XI. THE ROTATION OF CROPS + +Doubtless you know what is meant by rotation, for your teacher has +explained to you already how the earth rotates, or turns, on its axis +and revolves around the sun. When we speak of crop-rotation we mean not +only that the same crop should not be planted on the same land for two +successive years but that crops should follow one another in a regular +order. + +Many farmers do not follow a system of farming that involves a change of +crops. In some parts of the country the same fields are planted to corn +or wheat or cotton year after year. This is not a good practice and +sooner or later will wear out the soil completely, because the +soil-elements that furnish the food of that constant crop are soon +exhausted and good crop-production is no longer possible. + +Why is crop-rotation so necessary? There are different kinds of plant +food in the soil. If any one of these is used up, the soil of course +loses its power to feed plants properly. Now each crop uses more of some +of the different kinds of foods than others do, just as you like some +kinds of food better than others. But the crop cannot, as you can, learn +to use the kinds of food it does not like; it must use the kind that +nature fitted it to use. Not only do different crops feed upon different +soil foods, but they use different quantities of these foods. + +Now if a farmer plant the same crop in the same field each year, that +crop soon uses up all of the available plant food that it likes. Hence +the soil can no longer properly nourish the crop that has been year by +year robbing it. If that crop is to be successfully grown again on the +land, the exhausted element must be restored. + +[Illustration: FIG. 25. GRASS FOLLOWING CORN] + +This can be done in two ways: first, by finding out what element has +here been exhausted, and then restoring this element by means either of +commercial fertilizers or manure; second, by planting on the land crops +that feed on different food and that will allow or assist kind Mother +Nature "to repair her waste places." An illustration may help you to +remember this fact. Nitrogen is, as already explained, one of the +commonest plant foods. It may almost be called plant bread. The wheat +crop uses up a good deal of nitrogen. Suppose a field were planted in +wheat year after year. Most of the available nitrogen would be taken out +of the soil after a while, and a new wheat crop, if planted on the +field, would not get enough of its proper food to yield a paying +harvest. This same land, however, that could not grow wheat could +produce other crops that do not require so much nitrogen. For example, +it could grow cowpeas. Cowpeas, aided by their root-tubercles, are able +to gather from the air a great part of the nitrogen needed for their +growth. Thus a good crop of peas can be obtained even if there is little +available nitrogen in the soil. On the other hand wheat and corn and +cotton cannot use the free nitrogen of the air, and they suffer if there +is an insufficient quantity present in the soil; hence the necessity of +growing legumes to supply what is lacking. + +[Illustration: FIG. 26. COWPEAS AND CORN--AUGUST] + +Let us now see how easily plant food may be saved by the rotation of +crops. + +If you sow wheat in the autumn it is ready to be harvested in time for +planting cowpeas. Plow or disk the wheat stubble, and sow the same field +to cowpeas. If the wheat crop has exhausted the greater part of the +nitrogen of the soil, it makes no difference to the cowpea; for the +cowpea will get its nitrogen from the air and not only provide for its +own growth but will leave quantities of nitrogen in the queer nodules of +its roots for the crops coming after it in the rotation. + +[Illustration: FIG. 27. COWPEAS AND CORN--OCTOBER] + +If corn be planted, there should be a rotation in just the same way. The +corn plant, a summer grower, of course uses a certain portion of the +plant food stored in the soil. In order that the crop following the corn +may feed on what the corn did not use, this crop should be one that +requires a somewhat different food. Moreover, it should be one that fits +in well with corn so as to make a winter crop. We find just such a +plant in clover or wheat. Like the cowpea, all the varieties of clover +have on their roots tubercles that add the important element, nitrogen, +to the soil. + +From these facts is it not clear that if you wish to improve your land +quickly and keep it always fruitful you must practice crop-rotation? + + +AN ILLUSTRATION OF CROP-ROTATION + +Here are two systems of crop-rotation as practiced at one or more +agricultural experiment stations. Each furnishes an ideal plan for +keeping up land. + + ---------------------++----------------------++---------------------- + ---------------------++----------------------++---------------------- + FIRST YEAR || SECOND YEAR || THIRD YEAR + ----------+----------++-----------+----------++-----------+---------- + Summer | Winter || Summer | Winter || Summer | Winter + ----------+----------++-----------+----------++-----------+---------- + Corn | Crimson || Cotton | Wheat || Cowpeas | Rye for + | clover || | || | pasture + ----------+----------++-----------+----------++-----------+---------- + + or + + ----------+----------++-----------+----------++-----------+---------- + Summer | Winter || Summer | Winter || Summer | Winter + ----------+----------++-----------+----------++-----------+---------- + Corn | Wheat || Clover | Clover || Grass | Grass for + | || and grass | and grass|| |pasture or + | || | || | meadow + ----------+----------++-----------+----------++-----------+---------- + ----------+----------++-----------+----------++-----------+---------- + +In these rotations the cowpeas and clovers are nitrogen-gathering crops. +They not only furnish hay but they enrich the soil. The wheat, corn, and +cotton are money crops, but in addition they are cultivated crops; hence +they improve the physical condition of the soil and give opportunity to +kill weeds. The grasses and clovers are of course used for pasturage and +hay. This is only a suggested rotation. Work out one that will meet your +home need. + + + =EXERCISE= + + Let the pupils each present a system of rotation that includes the + crops raised at home. The system presented should as nearly as + possible meet the following requirements: + + 1. Legumes for gathering nitrogen. + 2. Money crops for cash income. + 3. Cultivated crops for tillage and weed-destruction. + 4. Food crops for feeding live stock. + + + + +CHAPTER III + +THE PLANT + + +SECTION XII. HOW A PLANT FEEDS FROM THE AIR + +If you partly burn a match you will see that it becomes black. This +black substance into which the match changes is called _carbon_. Examine +a fresh stick of charcoal, which is, as you no doubt know, burnt wood. +You see in the charcoal every fiber that you saw in the wood itself. +This means that every part of the plant contains carbon. How important, +then, is this substance to the plant! + +You will be surprised to know that the total amount of carbon in plants +comes from the air. All the carbon that a plant gets is taken in by the +leaves of the plant; not a particle is gathered by the roots. A large +tree, weighing perhaps 11,000 pounds, requires in its growth carbon from +16,000,000 cubic yards of air. + +Perhaps, after these statements, you may think there is danger that the +carbon of the air may sometime become exhausted. The air of the whole +world contains about 1,760,000,000,000 pounds of carbon. Moreover, this +is continually being added to by our fires and by the breath of animals. +When wood or coal is used for fuel the carbon of the burning substance +is returned to the air in the form of gas. Some large factories burn +great quantities of coal and thus turn much carbon back to the air. A +single factory in Germany is estimated to give back to the air daily +about 5,280,000 pounds of carbon. You see, then, that carbon is +constantly being put back into the air to replace that which is used by +growing plants. + +The carbon of the air can be used by none but green plants, and by them +only in the sunlight. We may compare the green coloring matter of the +leaf to a machine, and the sunlight to the power, or energy, which keeps +the machine in motion. By means, then, of sunlight and the green +coloring matter of the leaves, the plant secures carbon. The carbon +passes into the plant and is there made into two foods very necessary to +the plant; namely, starch and sugar. + +Sometimes the plant uses the starch and sugar immediately. At other +times it stores both away, as it does in the Irish and the sweet potato +and in beets, cabbage, peas, and beans. These plants are used as food by +man because they contain so much nourishment; that is, starch and sugar +which were stored away by the plant for its own future use. + + + =EXERCISE= + + Examine some charcoal. Can you see the rings of growth? Slightly + char paper, cloth, meat, sugar, starch, etc. What does the turning + black prove? What per cent of these substances do you think is pure + carbon? + + +SECTION XIII. THE SAP CURRENT + +The root-hairs take nourishment from the soil. The leaves manufacture +starch and sugar. These manufactured foods must be carried to all parts +of the plant. There are two currents to carry them. One passes from the +roots through the young wood to the leaves, and one, a downward current, +passes through the bark, carrying needed food to the roots (see Fig. +28). + +If you should injure the roots, the water supply to the leaves would be +cut off and the leaves would immediately wither. On the other hand, if +you remove the bark, that is, girdle the tree, you in no way interfere +with the water supply and the leaves do not wither. Girdling does, +however, interfere with the downward food current through the bark. + +[Illustration: FIG. 28 MOVEMENT OF THE SAP CURRENT] + +If the tree be girdled the roots sooner or later suffer from lack of +food supply from the leaves. Owing to this food stoppage the roots will +cease to grow and will soon be unable to take in sufficient water, and +then the leaves will begin to droop. This, however, may not happen until +several months after the girdling. Sometimes a partly girdled branch +grows much in thickness just above the girdle, as is shown in Fig. 29. +This extra growth seems to be due to a stoppage of the rich supply of +food which was on its way to the roots through the bark. It could go no +farther and was therefore used by the tree to make an unnatural growth +at this point. You will now understand how and why trees die when they +are girdled to clear new ground. + +[Illustration: FIG. 29. A THICKENING ABOVE THE WIRE THAT CAUSED THE +GIRDLING] + +It is, then, the general law of sap-movement that the upward current +from the roots passes through the woody portion of the trunk, and that +the current bearing the food made by the leaves passes downward through +the bark. + + + =EXERCISE= + + Let the teacher see that these and all other experiments are + performed by the pupils. Do not allow them to guess, but make them + see. + + Girdle valueless trees or saplings of several kinds, cutting the + bark away in a complete circle around the tree. Do not cut into the + wood. How long before the tree shows signs of injury? Girdle a + single small limb on a tree. What happens? Explain. + + +SECTION XIV. THE FLOWER AND THE SEED + +Some people think that the flowers by the wayside are for the purpose of +beautifying the world and increasing man's enjoyment. Do you think this +is true? Undoubtedly a flower is beautiful, and to be beautiful is one +of the uses of many flowers; but it is not the chief use of a flower. + +You know that when peach or apple blossoms are nipped by the spring +frost the fruit crop is in danger. The fruit of the plant bears the +seed, and the flower produces the fruit. That is its chief duty. + +[Illustration: FIG. 30. PARTS OF THE PISTIL] + +Do you know any plant that produces seed without flowers? Some one +answers, "The corn, the elm, and the maple all produce seed, but have no +flower." No, that is not correct. If you look closely you will find in +the spring very small flowers on the elm and on the maple, while the ear +and the tassel are really the blossoms of the corn plant. Every plant +that produces seed has flowers, although they may sometimes seem very +curious flowers. + +[Illustration: FIG. 31. A BUTTERCUP] + +Let us see what a flower really is. Take, for example, a buttercup, +cotton, tobacco, or plum blossom (see Figs. 31 and 32). You will find on +the outside a row of green leaves inclosing the flower when it is still +a bud. These leaves are the _sepals_. Next on the inside is a row of +colored leaves, or _petals_. Arranged inside of the petals are some +threadlike parts, each with a knob on the end. These are the _stamens_. +Examine one stamen closely (Fig. 33). On the knob at its tip you should +find, if the flower is fully open, some fine grains, or powder. In the +lily this powder is so abundant that in smelling the flower you often +brush a quantity of it off on your nose. This substance is called +_pollen_, and the knob on the end of the stamen, on which the pollen is +borne, is the _anther_. + +[Illustration: FIG. 32. A PLUM BLOSSOM] + +The pollen is of very great importance to the flower. Without it there +could be no seeds. The stamens as pollen-bearers, then, are very +important. But there is another part to each flower that is of equal +value. This part you will find in the center of the flower, inside the +circle of stamens. It is called the _pistil_ (Fig. 32). The swollen tip +of the pistil is the _stigma_. The swollen base of the pistil forms the +_ovary_. If you carefully cut open this ovary you will find in it +very small immature seeds. + +[Illustration: FIG. 33. STAMENS +_a_, anther; _f_, filament] + +Some plants bear all these parts in the same flower; that is, each +blossom has stamens, pistil, petals, and sepals. The pear blossom and +the tomato blossom represent such flowers. Other plants bear their +stamens and pistils in separate blossoms. Stamens and pistils may even +occur in separate plants, and some blossoms have no sepals or petals at +all. Look at the corn plant. Here the tassel is a cluster of many +flowers, each of which bears only stamens. The ear is likewise a cluster +of many flowers, each of which bears only a pistil. The dust that you +see falling from the tassel is the pollen, and the long silky threads of +the ear are the stigmas. + +[Illustration: FIG. 34. A TOMATO BLOSSOM] + +Now no plant can bear seeds unless the pollen of the stamen falls on the +stigma. Corn cannot therefore form seed unless the dust of the tassel +falls upon the silk. Did you ever notice how poorly the cob is filled on +a single cornstalk standing alone in a field? Do you see why? It is +because when a plant stands alone the wind blows the pollen away from +the tassel, and little or none is received on the stigmas below. + +[Illustration: FIG. 35. CUCUMBER BLOSSOMS] + +In the corn plant the stamens and pistils are separate; that is, they do +not occur on the same flower, although they are on the same plant. This +is also true of the cucumber (see Fig. 35). In many plants, however, +such as the hemp, hop, sassafras, willow, and others, the staminate +parts are on one plant and the pistillate parts are on another. This is +also true in several other cultivated plants. For example, in some +strawberries the stamens are absent or useless; that is, they bear no +good pollen. In such cases the grower must see to it that near by are +strawberry plants that bear stamens, in order that those plants which do +not bear pollen may become _pollinated_; that is, may have pollen +carried to them. After the stigma has been supplied with pollen, a +single pollen grain sends a threadlike sprout down through the stigma +into the ovary. This process, if successfully completed, is called +_fertilization_. + + + =EXERCISE= + + Examine several flowers and identify the parts named in the last + section. Try in the proper season to find the pollen on the maple, + willow, alder, and pine, and on wheat, cotton, and the + morning-glory. + + How fast does the ovary of the apple blossom enlarge? Measure one + and watch it closely from day to day. Can you find any plants that + have their stamens and ovaries on separate individuals? + + +SECTION XV. POLLINATION + +Nature has several interesting ways of bringing about pollination. In +the corn, willow, and pine the pollen is picked up by the wind and +carried away. Much of it is lost, but some reaches the stigmas, or +receptive parts, of other corn, willow, or pine flowers. This is a very +wasteful method, and all plants using it must provide much pollen. + +Many plants employ a much better method. They have learned how to make +insects bear their pollen. In plants of this type the parts of the +blossom are so shaped and so placed as to deposit pollen from the stamen +on the insect and to receive pollen from the insect on the stigmas. + +When you see the clumsy bumblebee clambering over and pushing his way +into a clover blossom, you may be sure that he is getting well dusted +with pollen and that the next blossom which he visits will secure a full +share on its stigmas. + +When flowers fit themselves to be pollinated by insects they can no +longer use the wind and are helpless if insects do not visit them. They +therefore cunningly plan two ways to invite the visits of insects. +First, they provide a sweet nectar as a repast for the insect visitor. +The nectar is a sugary solution found in the bottom of the flower and is +used by the visitor as food or to make honey. Second, flowers advertise +to let each insect know that they have something for it. The advertising +is done either by showy colors or by perfume. Insects have wonderful +powers of smell. When you see showy flowers or smell fragrant ones, you +will know that such flowers are advertising the presence either of +nectar or of pollen (to make beebread) and that such flowers depend on +insects for pollination. + +[Illustration: FIG. 36. BEES CARRYING POLLEN] + +A season of heavy, cold rains during blossoming-time may often injure +the fruit crop by preventing insects from carrying pollen from flower to +flower. You now also understand why plants often fail to produce seeds +indoors. Since they are shut in, they cannot receive proper insect +visits. Plants such as tomatoes or other garden fruits dependent upon +insect pollination must, if raised in the greenhouse where insects +cannot visit them, be pollinated by hand. + + + =EXERCISE= + + Exclude insect visitors from some flower or flower cluster, for + example, clover, by covering with a paper bag, and see whether the + flower can produce seeds that are capable of growing. Compare as to + number and vitality the seeds of such a flower with those of an + uncovered flower. Observe insects closely. Do you ever find pollen + on them? What kinds of insects visit the clover? the cowpea? the + sourwood? the flax? Is wheat pollinated by insects or by the wind + or by some other means? Do bees fly in rainy weather? How will a + long rainy season at blossoming-time affect the apple crop? Why? + Should bees be kept in an orchard? Why? + + +SECTION XVI. CROSSES, HYBRIDS, AND CROSS-POLLINATION + +In our study of flowers and their pollination we have seen that the seed +is usually the descendant of two parents, or at least of two organs--one +the ovary, producing the seed; the other the pollen, which is necessary +to fertilize the ovary. + +It happens that sometimes the pollen of one blossom fertilizes the ovary +of its own flower, but more often the pollen from one plant fertilizes +the ovary of another plant. This latter method is called +_cross-pollination_. As a rule cross-pollination makes seed that will +produce a better plant than simple pollination would. Cross-pollination +by hand is often used by plant-breeders when, for purposes of +seed-selection, a specially strong plant is desired. The steps in hand +pollination are as follows: (1) remove the anthers before they open, to +prevent them from pollinating the stigma (the steps in this process are +illustrated in Figs. 37, 38-39); (2) cover the flower thus treated with +a paper bag to prevent stray pollen from getting on it (see Fig. 40); +(3) when the ovary is sufficiently developed, carry pollen to the stigma +by hand from the anthers of another plant which you have selected to +furnish it, and rebag to keep out any stray pollen which might +accidentally get in; (4) collect the seeds when they are mature and +label them properly. + +Hand pollination has this advantage--you know both parents of your seed. +If pollination occur naturally you know the maternal but have no means +of judging the paternal parent. You can readily see, therefore, how hand +pollination enables you to secure seed derived from two well-behaved +parents. + +Sometimes we can breed one kind of plant on another. The result of such +cross-breeding is known as a _hybrid_. In the animal kingdom the mule is +a common example of this cross-breeding. Plant hybrids were formerly +called mules also, but this suggestive term is almost out of use. + +[Illustration: FIG. 37 +The bud on right at top is in proper condition for removal of anthers; +the anthers have been removed from the buds below] + +It is only when plants of two distinct kinds are crossed that the result +is called a hybrid; for example, a blackjack oak on a white oak, an +apple on a pear. If the parent plants are closely related, for example, +two kinds of apples, the resulting plant is known simply as a _cross_. + +Hybrids and crosses are valuable in that they usually differ from both +parents and yet combine some qualities of each. + +[Illustration: FIG. 38. ORANGE BLOSSOM PREPARED FOR CROSSING +First, bud; second, anthers unremoved; third, anthers removed] + +[Illustration: FIG. 39. TOMATO BLOSSOM READY TO CROSS +First, bud; second, anthers unremoved; third, anthers removed] + +[Illustration: FIG. 40. +First, blossom bagged to keep out stray pollen; second, fruit bagged for +protection] + +They often leave off some of the qualities of the parent +plants and at other times have such qualities more markedly than did +their parents. Thus they often produce an interesting new kind of plant. +Sometimes we are able by hybridization to combine in one plant the good +qualities of two other plants and thus make a great advance in +agriculture. The new forms brought about by hybridization may be fixed, +or made permanent, by such selection as is mentioned in Section XVIII. +Hybridization is of great aid in originating new plants. + +It often happens that a plant will be more fruitful when pollinated by +one variety than by some other variety. This is well illustrated in Fig. +41. A fruit-grower or farmer should know much about these subjects +before selecting varieties for his orchard, vineyard, etc. + + + =EXERCISE= + + With the help of your teacher try to cross some plants. Such an + experiment will take time, but will be most interesting. You must + remember that many crosses must be attempted in order to gain + success with even a few. + + +SECTION XVII. PROPAGATION BY BUDS + +It is the business of the farmer to make plants grow, or, as it is +generally called, to propagate plants. This he does in one of two ways: +by buds (that is, by small pieces cut from parent plants), or by seeds. +The chief aim in both methods should be to secure in the most convenient +manner the best-paying plants. + +Many plants are most easily and quickly propagated by buds; for example, +the grape, red raspberry, fig, and many others that we cultivate for the +flower only, such as the carnation, geranium, rose, and begonia. + +[Illustration: FIG. 41. +Brighton pollinated by 1, Salem; 2, Creveling; 3, Lindley; 4, Brighton; +5, Self-pollinated; 6, Nectar; 7, Jefferson; 8, Niagara] + +In growing plants from cuttings, a piece is taken from the kind of plant +that one wishes to grow. The greatest care must be exercised in order to +get a healthy cutting. If we take a cutting from a poor plant, what can +we expect but to grow a poor plant like the one from which our cutting +was taken? On the other hand, if a fine, strong, vigorous, fruitful +plant be selected, we shall expect to grow just such a fine, healthy, +fruitful plant. + +We expect the cutting to make exactly the same variety of plant as the +parent stock. We must therefore decide on the variety of berry, grape, +fig, carnation, or rose that we wish to propagate, and then look for the +strongest and most promising plants of this variety within our reach. +The utmost care will not produce a fine plant if we start from poor +stock. + +[Illustration: FIG. 42. GERANIUM CUTTING +Dotted line shows depth to which cutting should be planted] + +What qualities are most desirable in a plant from which cuttings are to +be taken? First, it should be productive, hardy, and suited to your +climate and your needs; second, it should be healthy. Do not take +cuttings from a diseased plant, since the cutting may carry the +disease. + +Cuttings may be taken from various parts of the plant, sometimes even +from parts of the leaf, as in the begonia (Fig. 46). More often, +however, they are drawn from parts of the stem (Figs. 43-45). As to the +age of the twig from which the cutting is to be taken, Professor Bailey +says: "For most plants the proper age or maturity of wood for the making +of cuttings may be determined by giving the twig a quick bend; if it +snaps and hangs by the bark, it is in proper condition. If it bends +without breaking, it is too young and soft or too old. If it splinters, +it is too old and woody." Some plants, as the geranium (Fig. 42), +succeed best if the cuttings from which they are grown are taken from +soft, young parts of the plant; others, for example, the grape or rose, +do better when the cutting is made from more mature wood. + +[Illustration: FIG. 43 GRAPE CUTTING +Showing depth to which cutting should be planted] + +[Illustration: FIG. 44. CARNATION CUTTING] + +Cuttings may vary in size and may include one or more buds. After a +hardy, vigorous cutting is made, insert it about one half or one third +of its length in soil. A soil free from organic matter is much the best, +since in such soil the cuttings are much less liable to disease. A fine, +clean sand is commonly used by professional gardeners. When cuttings +have rooted well--this may require a month or more--they may be +transplanted to larger pots. + +Sometimes, instead of cutting off a piece and rooting it, portions of +branches are made to root before they are separated from the parent +plant. This method is often followed, and is known as _layering_. It is +a simple process. Just bend the tip of a bough down and bury it in the +earth (see Fig. 47). The black raspberry forms layers naturally, but +gardeners often aid it by burying the over-hanging tips in the earth, so +that more tips may easily take root. Strawberries develop runners that +root themselves in a similar fashion. + +Grafts and buds are really cuttings which, instead of being buried in +sand to produce roots of their own, are set on the roots of other +plants. + +[Illustration: FIG. 45. ROSE CUTTING] + +Grafting and budding are practiced when these methods are more +convenient than cuttings or when the gardener thinks there is danger of +failure to get plants to take root as cuttings. Neither grafting nor +budding is, however, necessary for the raspberry or the grape, for these +propagate most readily from cuttings. + +It is often the case that a budded or grafted plant is more fruitful +than a plant on its own roots. In cases of this kind, of course, grafts +or buds are used. + +The white, or Irish, potato is usually propagated from pieces of the +potato itself. Each piece used for planting bears one eye or more. The +potato itself is really an underground stem and the eyes are buds. This +method of propagation is therefore really a peculiar kind of cutting. + +Since the eye is a bud and our potato plant for next year is to develop +from this bud, it is of much importance, as we have seen, to know +exactly what _kind_ of plant our potato comes from. If the potato is +taken from a small plant that had but a few poor potatoes in the hill, +we may expect the bud to produce a similar plant and a correspondingly +poor crop. We must see to it, then, that our seed potatoes are drawn +from vines that were good producers, because new potato plants are like +the plants from which they were grown. Of course when our potatoes are +in the bin we cannot tell from what kind of plants they came. We must +therefore _select our seed potatoes in the field_. Seed potatoes should +always be selected from those hills that produce most bountifully. Be +assured that the increased yield will richly repay this care in +selecting. It matters not so much whether the seed potato be large or +small; it must, however, come from a hill bearing a large yield of fine +potatoes. + +[Illustration: FIG. 46. BEGONIA-LEAF CUTTING] + +Sweet-potato plants are produced from shoots, or growing buds, taken +from the potato itself, so that in their case too the piece that we use +in propagating is a part of the original plant, and will therefore be +like it under similar conditions. Just as with the Irish potato, it is +important to know how good a yielder you are planting. You should watch +during harvest and select for propagation for the next year only such +plants as yield best. + +We should exercise fully as much care in selecting proper individuals +from which to make a cutting or a layer as we do in selecting a proper +animal to breed from. Just as we select the finest Jersey in the herd +for breeding purposes, so we should choose first the variety of plant we +desire and then the finest individual plant of that variety. + +If the variety of the potato that we desire to raise be Early Rose, it +is not enough to select _any_ Early Rose plants, but the very best Early +Rose plants, to furnish our seed. + +[Illustration: FIG. 47. LAYERING] + +It is not enough to select large, fine potatoes for cuttings. A large +potato may not produce a bountifully yielding plant. _It will produce a +plant like the one that produced it._ It may be that this one large +potato was the only one produced by the original plant. If so, the plant +that grows from it will tend to be similarly unproductive. Thus you see +the importance of _selecting in the field a plant that has exactly the +qualities desired in the new plant_. + +One of the main reasons why gardeners raise plants from buds instead of +from seeds is that the seed of many plants will not produce plants like +the parent. This failure to "come true," as it is called, is sometimes +of value, for it occasionally leads to improvement. For example, suppose +that a thousand apple or other fruit or flower seeds from plants usually +propagated by cuttings be planted; it may be that one out of a thousand +or a million will be a very valuable plant. If a valuable plant be so +produced, it should be most carefully guarded, multiplied by cuttings or +grafts, and introduced far and wide. It is in this way that new +varieties of fruits and flowers are produced from time to time. + +Sometimes, too, a single bud on a tree will differ from the other buds +and will produce a branch different from the other branches. This is +known as _bud variation_. When there is thus developed a branch which +happens to be of a superior kind, it should be propagated by cuttings +just as you would propagate it if it had originated from a seed. + +[Illustration: FIG. 48. CURRANT CUTTING] + +Mr. Gideon of Minnesota planted many apple seeds, and from them all +raised one tree that was very fruitful, finely flavored, and able to +withstand the cold Minnesota winter. This tree he multiplied by grafts +and named the Wealthy apple. It is said that in giving this one apple to +the world he benefited mankind to the value of more than one million +dollars. It will be well to watch for any valuable bud or seed variant +and never let a promising one be lost. Plants grown in this way from +seeds are usually spoken of as seedlings. + +[Illustration: A LUSCIOUS AND EASILY GROWN BERRY] + + +PLANTS TO BE PROPAGATED FROM BUDS + +The following list gives the names and methods by which our common +garden fruits and flowers are propagated: + + _Figs_: use cuttings 8 to 10 inches long or layer. + _Grapes_: use long cuttings, layer, or graft upon old vines. + + _Apples_: graft upon seedlings, usually crab seedlings one + year old. + + _Pears_: bud upon pear seedlings. + + _Cherries_: bud upon cherry stock. + + _Plums_: bud upon peach stock. + + _Peaches_: bud upon peach or plum seedlings. + + _Quinces_: use cuttings or layer. + + _Blackberries_: propagate by suckers; cut from parent stem. + + _Black raspberries_: layer; remove old stem. + + _Red raspberries_: propagate by root-cuttings or suckers. + + _Strawberries_: propagate by runners. + + _Currants_ and _gooseberries_: use long cuttings (these plants + grow well only in cool climates; if attempted in warm + climates, set in cold exposure). + + _Carnations_, _geraniums_, _roses_, _begonias_, etc.: propagate by + cuttings rooted in sand and then transplanted to small pots. + + =EXERCISE= + + Propagate fruits (grape, fig, strawberry) of various kinds; also + ornamental plants. How long does it take them to root? Geraniums + rooted in the spring will bloom in the fall. Do you know any one + who selects seed potatoes properly? Make a careful selection of + seed at the next harvest-time. + + +SECTION XVIII. PLANT SEEDING + +In propagating by seed, as in reproducing by buds, we select a portion +of the parent plant--for a seed is surely a part of the parent +plant--and place it in the ground. There is, however, one great +difference between a seed and a bud. The bud is really a piece of the +parent plant, but a piece of _one_ plant only, while a seed comes from +the parts of two plants. + +You will understand this fully if you read carefully Sections XIV-XVI. +Since the seed is made of two plants, the plant that springs from a seed +is much more likely to differ from its mother plant, that is, from the +plant that produces the seed, than is a plant produced merely by buds. +In some cases plants "come true to seed" very accurately. In others they +vary greatly. For example, when we plant the seed of wheat, turnips, +rye, onions, tomatoes, tobacco, or cotton, we get plants that are in +most respects like the parent plant. On the other hand the seed of a +Crawford peach or a Baldwin apple or a Bartlett pear will not produce +plants like its parent, but will rather resemble its wild forefathers. +These seedlings, thus taking after their ancestors, are always far +inferior to our present cultivated forms. In such cases seeding is not +practicable, and we must resort to bud propagation of one sort or +another. + +While in a few plants like those just mentioned the seed does not "come +true," most plants, for example, cotton, tobacco, and others, do "come +true." When we plant King cotton we may expect to raise King cotton. +There will be, however, as every one knows, some or even considerable +variation in the field. Some plants, even in exactly the same soil, will +be better than the average, and some will be poorer. Now we see this +variation in the plants of our field, and we believe that the plant will +be in the main like its parent. What should we learn from this? Surely +that if we wish to produce sturdy, healthy, productive plants we must go +into our fields and _pick out just such plants to secure seed from as we +wish to produce another year_. If we wait until the seed is separated +from the plant that produced it before we select our cotton seed, we +shall be planting seed from poor as well as from good plants, and must +be content with a crop of just such stock as we have planted. By +selecting seed from the most productive plants _in the field_ and by +repeating the selection each year, you can continually improve the breed +of the plant you are raising. In selecting seed for cotton you may +follow the plan suggested below for wheat. + +[Illustration: FIGS. 49 AND 50. CHRYSANTHEMUMS AND ASPARAGUS] + +The difference that you see between the wild and the cultivated +chrysanthemums and between the samples of asparagus shown in Figs. 49 +and 50 was brought about by just such continuous seed-selection from the +kind of plant wanted. + +[Illustration: FIG. 51. TWO VARIETIES OF FLAX FROM ONE PARENT STOCK] + +By the careful selection of seed from the longest flax plants the +increase in length shown in the accompanying figure was gained. The +selection of seed from those plants bearing the most seed, regardless of +the height of the plant, has produced flax like that to the right in the +illustration. These two kinds of flax are from the same parent stock, +but slight differences have been emphasized by continued seed-selection, +until we now have really two varieties of flax, one a heavy seed-bearer, +the other producing a long fiber. + +You can in a similar way improve your cotton or any other seed crop. +Sugar beets have been made by seed-selection to produce about double the +percentage of sugar that they did a few years ago. Preparing and +tilling land costs too much in money and work to allow the land to be +planted with poor seed. When you are trying by seed-selection to +increase the yield of cotton, there are two principles that should be +borne in mind: first, seed should be chosen only from plants that bear +many well-filled bolls of long-staple cotton; second, seed should be +taken from no plant that does not by its healthy condition show +hardihood in resisting disease and drouth. + +The plan of choosing seeds from selected plants may be applied to wheat; +but it would of course be too time-consuming to select enough single +wheat plants to furnish all of the seed wheat for the next year. In this +case adopt the following plan: In Fig. 52 let _A_ represent the total +size of your wheat field and let _B_ represent a plat large enough to +furnish seed for the whole field. At harvest-time go into section _A_ +and select the best plants you can find. Pick the heads of these and +thresh them by hand. The seed so obtained must be carefully saved for +your next sowing. + +[Illustration: FIG. 52.] + +In the fall sow these selected seeds in area _B_. This area should +produce the best wheat. At the next harvest cull not from the whole +field but from the finest plants of plat _B_, and again save these as +seed for plat _B_. Use the unculled seed from plat _B_ to sow your crop. +By following this plan continuously you will every year have seed from +several generations of choice plants, and each year you will improve +your seed. + +It is of course advisable to move your seed plat _B_ every year or two. +For the new plat select land that has recently been planted in legumes. +Always give this plat unwearying care. + +In the selection of plants from which to get seed, you must know what +kind of plants are really the best seed plants. First, _you must not +regard single heads or grains, but must select seed from the most +perfect plant_, looking at the plant as a whole and not at any single +part of it. A first consideration is yield. Select the plants that yield +best and are at the same time resistant to drouth, resistant to rust and +to winter, early to ripen, plump of grain, and nonshattering. What a +fine thing it would be to find even one plant free from rust in the +midst of a rusted field! It would mean a _rust-resistant plant_. Its +offspring also would probably be rust-resistant. If you should ever find +such a plant, be sure to save its seed and plant it in a plat by itself. +The next year again save seed from those plants least rusted. Possibly +you can develop a rust-proof race of wheat! Keep your eyes open. + +In England the average yield of wheat is thirty bushels an acre, in the +United States it is less than fifteen bushels! In some states the yield +is even less than nine bushels an acre. Let us select our seed with +care, as the English people do, and then we can increase our yield. By +careful seed-selection a plant-breeder in Minnesota increased the yield +of his wheat by one fourth. Think what it would mean if twenty-five per +cent were added to the world's supply of wheat at comparatively no cost; +that is, at the mere cost of careful seed-selection. This would mean an +addition to the world's income of about $500,000,000 each year. The +United States would get about one fifth of this profit. + +It often happens that a single plant in a crop of corn, cotton, or wheat +will be far superior to all others in the field. Such a plant deserves +special care. Do not use it merely as a seed plant, but carefully plant +its seeds apart and tend carefully. The following season select the best +of its offspring as favorites again. Repeat this selection and culture +for several years until you fix the variety. This is the way new +varieties are originated from plants propagated by seed. + +In 1862 Mr. Abraham Fultz of Pennsylvania, while passing through a field +of bearded wheat, found three heads of beardless, or bald, wheat. These +he sowed by themselves that year, and as they turned out specially +productive he continued to sow this new variety. Soon he had enough seed +to distribute over the country. It became known as the Fultz wheat and +is to-day one of the best varieties in the United States and in a number +of foreign countries. Think how many bushels of wheat have been added to +the world's annual supply by a few moments of intelligent observation +and action on the part of this one man! He saw his opportunity and used +it. How many similar opportunities do you think are lost? How much does +your state or country lose thereby? + + + =EXERCISE= + + Select one hundred seeds from a good, and one hundred from a poor, + plant of the same variety. Sow them in two plats far enough apart + to avoid cross-pollination, yet try to have soil conditions about + the same. Give each the same care and compare the yield. Try this + with corn, cotton, and wheat. Select seeds from the best plant in + your good plat and from the poorest in your poor plat and repeat + the experiment. This will require but a few feet of ground, and the + good plat will pay for itself in yield, while the poor plat will + more than pay in the lesson that it will teach you. + + Write to the Department of Agriculture, Washington, D.C., and to + your state experiment station for bulletins concerning + seed-selection and methods of plant-improvement. + + +SECTION XIX. SELECTING SEED CORN + +If a farmer would raise good crops he must, as already stated, select +good seed. Many of the farmer's disappointments in the quantity and +quality of his crops--disappointments often thought to come from other +causes--are the result of planting poor seed. Seeds not fully ripened, +if they grow at all, produce imperfect plants. Good seed, therefore, is +the first thing necessary for a good crop. The seed of perfect plants +only should be saved. + +By wise and persistent selection, made in the field before the crop is +fully matured, corn can be improved in size and made to mature earlier. +Gather ears only from the most productive plants and save only the +largest and best kernels. + +[Illustration: FIG. 53. THE KIND OF EAR TO SELECT] + +You have no doubt seen the common American blackbirds that usually +migrate and feed in such large numbers. They all look alike in every +way. Now, has it ever occurred to you to ask why all blackbirds are +black? The blackbirds are black simply because their parents are black. + +Now in the same way that the young blackbirds resemble their parents, +corn will resemble its parent stock. How many ears of corn do you find +on a stalk? One, two, sometimes three or four. You find two ears of corn +on a stalk because it is the nature of that particular stalk to produce +two ears. In the same way the nature of some stalks is to produce but +one ear, while it is the nature of others sometimes to produce two or +more. + +This resemblance of offspring to parent is known to scientists as +heredity, or as "like producing like." + +Some Southern corn-breeders take advantage of this law to improve their +corn crop. If a stalk can be made to produce two ears of corn just as +large as the single ear that most stalks bear, we shall get twice as +much corn from a field in which the "two-eared" variety is planted. In +the North and West the best varieties of corn have been selected to make +but one ear to the stalk. It is generally believed that this is the best +practice for the shorter growing seasons of the colder states. + +[Illustration: FIG. 54. SELECT SEED FROM A STALK LIKE THAT ON LEFT] + +These facts ought to be very helpful to us next year when our fathers +are planting corn. We should get them to plant seed secured only from +stalks that produced the most corn, whether the stalk had two or more +ears or only one. If we follow this plan year by year, each acre of land +will be made to produce more kernels and hence a larger crop of corn, +and yet no more work will be required to raise the crop. + +In addition to enlarging the yield of corn, you can, by proper selection +of the best and most productive plants in the field, grow a new variety +of seed corn. To do this you need only take the largest and best +kernels from stalks bearing two ears; plant these, and at the next +harvest again save the best kernels from stalks bearing the best ears. +If you keep up this practice with great care for several years, you will +get a vigorous, fruitful variety that will command a high price for +seed. + + + =EXPERIMENT= + + [Illustration: FIG. 55. IMPROVEMENT OF CORN BY SELECTION + Boone County white corn on left, and original type, from which it + was developed by selection, on right] + + Every school boy and girl can make this experiment at leisure. From + your own field get two ears of corn, one from a stalk bearing only + one ear and the other from a stalk bearing two well-grown ears. + Plant the grains from one ear in one plat, and the grains from the + other in a plat of equal size. Use for both the same soil and the + same fertilizer. Cultivate both plats in the same way. When the + crop is ready to harvest, husk the corn, count the ears, and weigh + the corn. Then write a short essay on your work and on the results + and get your teacher to correct the story for your home paper. + + +SECTION XX. WEEDS + +Have you ever noticed that some weeds are killed by one particular +method, but that this same method may entirely fail to kill other kinds +of weeds? If we wish to free our fields of weeds with the greatest ease, +we must know the nature of each kind of weed and then attack it in the +way in which we can most readily destroy it. + +[Illustration: FIG. 56. PIGWEED] + +The ordinary pigweed (Fig. 56) differs from many other weeds in that it +lives for only one year. When winter comes, it must die. Each plant, +however, bears a great number of seeds. If we can prevent the plant from +bearing seed in its first year, there will not be many seeds to come up +the next season. In fact, only those seeds that were too deeply buried +in the soil to come up the previous spring will be left, and of these +two-year-old seeds many will not germinate. During the next season some +old seeds will produce plants, but the number will be very much +diminished. If care be exercised to prevent the pigweed from seeding +again, and the same watchfulness be continued for a few seasons, this +weed will be almost entirely driven from our fields. + +A plant like the pigweed, which lives only one year, is called an +_annual_ and is one of the easiest weeds to destroy. Mustard, plantain, +chess, dodder, cockle, crab grass, and Jimson weed are a few of our most +disagreeable annual weeds. + +The best time to kill any weed is when it is very small; therefore the +ground in early spring should be constantly stirred in order to kill the +young weeds before they grow to be strong and hardy. + +[Illustration: FIG. 57. WILD CARROT] + +The wild carrot differs from an annual in this way: it lives throughout +one whole year without producing seeds. During its first year it +accumulates a quantity of nourishment in the root, then rests in the +winter. Throughout the following summer it uses this nourishment rapidly +to produce its flowers and seeds. Then the plant dies. Plants that live +through two seasons in this way are called _biennials_. Weeds of this +kind may be destroyed by _cutting the roots below the leaves_ with a +grubbing-hoe or spud. A spud may be described as a chisel on a long +handle (see Fig. 58). If biennials are not cut low enough they will +branch out anew and make many seeds. Among the most common biennials are +the thistle, moth mullein, wild carrot, wild parsnip, and burdock. + +[Illustration: FIG. 58. A SPUD] + +[Illustration: FIG. 59. HOUND'S TONGUE] + +A third group of weeds consists of those that live for more than two +years. These weeds are usually most difficult to kill. They propagate by +means of running rootstocks as well as by seeds. Plants that live more +than two seasons are known as _perennials_ and include, for example, +many grasses, dock, Canada thistle, poison ivy, passion flower, horse +nettle, etc. There are many methods of destroying perennial weeds. They +may be dug entirely out and removed. Sometimes in small areas they may +be killed by crude sulphuric acid or may be starved by covering them +with boards or a straw stack or in some other convenient way. A method +that is very effective is to smother the weeds by a dense growth of +some other plant, for example, cowpeas or buckwheat. Cowpeas are to be +preferred, since they also enrich the soil by the nitrogen that the +root-tubercles gather. + +[Illustration: FIG. 60. CANADA THISTLE] + +Weeds do injury in numerous ways; they shade the crop, steal its +nourishment, and waste its moisture. Perhaps their only service is to +make lazy people till their crops. + + + =EXERCISE= + + You should learn to know by name the twenty worst weeds of your + vicinity and to recognize their seeds. If there are any weeds you + are not able to recognize, send a sample of each to your state + experiment station. Make a collection, properly labeled, of weeds + and weed seeds for your school. + + +SECTION XXI. SEED PURITY AND VITALITY + +Seeds produce plants. The difference between a large and a small yield +may depend upon the kind of plants we raise, and the kind of plant in +turn is dependent upon the seeds that we sow. + +Two things are important in the selection of seeds--purity and vitality. +Seeds should be _pure_; that is, when sown they should produce no other +plant than the one that we wish to raise. They should be able to grow. +The ability of a seed to grow is termed its _vitality_. Good seed should +be nearly or quite pure and should possess high vitality. The vitality +of seeds is expressed as a per cent; for example, if 97 seeds out of 100 +germinate, or sprout, the vitality is said to be 97. The older the seed +the less is its vitality, except in a few rare instances in which seeds +cannot germinate under two or three years. + +Cucumber seeds may show 90 per cent vitality when they are one year old, +75 per cent when two years old, and 70 per cent when three years +old--the per cent of vitality diminishing with increase of years. The +average length of life of the seeds of cultivated plants is short: for +example, the tomato lives four years; corn, two years; the onion, two +years; the radish, five years. The cucumber seed may retain life after +ten years; but the seeds of this plant too lose their vitality with an +increase in years. + +It is important when buying seeds to test them for purity and vitality. +Dealers who are not honest often sell old seeds, although they know that +seeds decrease in value with age. Sometimes, however, to cloak +dishonesty they mix some new seeds with the old, or bleach old and +yellow seeds in order to make them resemble fresh ones. + +It is important, therefore, that all seeds bought of dealers should be +thoroughly examined and tested; for if they do not grow, we not only pay +for that which is useless but we are also in great danger of producing +so few plants in our fields that we shall not get full use of the land, +and thus we may suffer a more serious loss than merely paying for a few +dead seeds. It will therefore be both interesting and profitable to +learn how to test the vitality of seeds. + +To test vitality plant one hundred seeds in a pot of earth or in damp +sand, or place them between moist pieces of flannel, and take care to +keep them moist and warm. Count those that germinate and thus determine +the percentage of vitality. Germinating between flannel is much quicker +than planting in earth. Care should be used to keep mice away from +germinating seeds. (See Fig. 61.) + +[Illustration: FIG. 61. A SEED-GERMINATOR +Consisting of two soup plates, some sand, and a piece of cloth] + +Sometimes the appearance of a package will show whether the seed has +been kept in stock a long time. It is, however, much more difficult to +find out whether the seeds are pure. You can of course easily +distinguish seeds that differ much from those you wish to plant, but +often certain weed seeds are so nearly like certain crop seeds as not to +be easily recognized by the eye. Thus the dodder or "love vine," which +so often ruins the clover crop, has seeds closely resembling clover +seeds. The chess, or cheat, has seeds so nearly like oats that only a +close observer can tell them apart. However, if you watch the seeds that +you buy, and study the appearance of crop seeds, you may become expert +in recognizing those that have no place in your planting. + +One case is reported in which a seed-dealer intentionally allowed an +impurity of 30 per cent to remain in the crop seeds, and this impurity +was mainly of weed seeds. There were 450,000 of one kind and 288,000 of +another in each pound of seed. Think of planting weeds at that rate! +Sometimes three fourths of the seeds you buy are weed seeds. + +In purchasing seeds the only safe plan is to buy of dealers whose +reputation can be relied upon. + +It not seldom happens that seeds, like corn, are stored in open cribs or +barns before the moisture is entirely dried out of the seeds. Such seeds +are liable to be frozen during a severe winter, and of course if this +happens they will not sprout the following spring. The only way to tell +whether such seeds have been killed is to test samples of them for +vitality. Testing is easy; replanting is costly and often results in a +short crop. + +[Illustration: FIG. 62. IMPURITIES IN SEEDS +Tube 1 represents one pound of redtop grass as bought; Tube 2, amount of +pure redtop grass seeds in Tube 1; Tube 3, amount of chaff and dirt in +Tube 1; Tube 4, amount of weed seeds in Tube 1; Tube 5, amount of total +waste in Tube 1; Tube 6, amount of pure germinable seeds in Tube 1] + + =EXERCISE= + + Examine seeds both for vitality and purity. Write for farmers' + bulletins on both these subjects. What would be the loss to a + farmer who planted a ten-acre clover field with seeds that were 80 + per cent bad? Can you recognize the seeds of the principal + cultivated plants? Germinate some beet seeds. What per cent comes + up? Can you explain? Collect for your school as many kinds of wild + and cultivated seeds as you can. + + + + +CHAPTER IV + +HOW TO RAISE A FRUIT TREE + + +Let each pupil grow an apple tree this year and attempt to make it the +best in his neighborhood. In your attempt suppose you try the following +plan. In the fall take the seed of an apple--a crab-apple is good--and +keep it in a cool place during the winter. The simplest way to do this +is to bury it in damp sand. In the spring plant it in a rich, loose +soil. + +Great care must be taken of the young shoot as soon as it appears above +the ground. You want to make it grow as tall and as straight as possible +during this first year of its life, hence you should give it rich soil +and protect it from animals. Before the ground freezes in the fall take +up the young tree with the soil that was around it and keep it all +winter in a cool, damp place. + +Now when spring comes it will not do to set out the carefully tended +tree, for an apple tree from seed will not be a tree like its parent, +but will tend to resemble a more distant ancestor. The distant ancestor +that the young apple tree is most likely to take after is the wild +apple, which is small, sour, and otherwise far inferior to the fruit we +wish to grow. It makes little difference, therefore, what kind of apple +seed we plant, since in any event we cannot be sure that the tree grown +from it will bear fruit worth having unless we force it to do so. + +[Illustration: FIG. 63. A YOUNG FRUIT-GROWER] + + +SECTION XXII. GRAFTING + +By a process known as _grafting_ you can force your tree to produce +whatever variety of apple you desire. Many people raise fruit trees +directly from seed without grafting. Thus they often produce really +worthless trees. By grafting they would make sure not only of having +good trees rather than poor ones but also of having the particular kind +of fruit that they wish. Hence you must now graft your tree. + +First you must decide what variety of apple you want to grow on the +tree. The Magnum Bonum is a great favorite as a fall apple. The Winesap +is a good winter apple, while the Red Astrachan is a profitable early +apple, especially in the lowland of the coast region. The Northern Spy, +Æsop, and Spitzenburg are also admirable kinds. Possibly some other +apple that you know may suit your taste and needs better than any of +these varieties. + +If you have decided to raise an Æsop or a Magnum Bonum or a Winesap, you +must now cut a twig from the tree of your choice and graft it upon the +little tree that you have raised. Choose a twig that is about the +thickness of the young tree at the point where you wish to graft. Be +careful to take the shoot from a vigorous, healthy part of the tree. + +[Illustration: FIG. 64. TONGUE GRAFTING] + +There are many ways in which you may join the chosen shoot or twig upon +the young tree, but perhaps the best one for you to use is known as +_tongue grafting_. This is illustrated in Fig. 64. The upper part, _b_, +which is the shoot or twig that you cut from the tree, is known as the +_scion_; the lower part, _a_, which is the original tree, is called the +_stock_. + +Cut the scion and stock as shown in Fig. 64. Join the cut end of the +scion to the cut end of the stock. When you join them, notice that under +the bark of each there is a thin layer of soft, juicy tissue. This is +called the _cambium_. To make a successful graft the cambium in the +scion must exactly join the cambium in the stock. Be careful, then, to +see that cambium meets cambium. You now see why grafting can be more +successfully done if you select a scion and stock of nearly the same +size. + +[Illustration: FIG. 65. A COMPLETED GRAFT +Showing scion and stock from which it was made] + +After fitting the parts closely together, bind them with cotton yarn +(see Fig. 65) that has been coated with grafting wax. This wax is made +of equal parts of tallow, beeswax, and linseed oil. Smear the wax +thoroughly over the whole joint, and make sure that the joint is +completely air-tight. + +[Illustration: FIG. 66. +To make a root graft, cut along the slanting line] + +The best time to make this graft is when scion and stock are dormant, +that is, when they are not in leaf. During the winter, say in February, +is the best time to graft the tree. Set the grafted tree away again in +damp sand until spring, then plant it in loose, rich soil. + +Since all parts growing above the graft will be of the same kind as the +scion, while all branches below it will be like the stock, it is well to +graft low on the stock or even upon the root itself. The slanting double +line in Fig. 66 shows the proper place to cut off for such grafting. + +[Illustration: FIG. 67. A COMPLETED ROOT GRAFT] + +If you like you may sometime make the interesting and valuable +experiment of grafting scions from various kinds of apple trees on the +branches of one stock. In this way you can secure a tree bearing a +number of kinds of fruit. You may thus raise the Bonum, Red Astrachan, +Winesap, and as many other varieties of apples as you wish, upon one +tree. For this experiment, however, you will find it better to resort to +_cleft grafting_, which is illustrated in Fig. 68. + +[Illustration: FIG. 68. CLEFT GRAFTING] + +Luther Burbank, the originator of the Burbank potato, in attempting to +find a variety of apple suited to the climate of California, grafted +more than five hundred kinds of apple scions on one tree, so that he +might watch them side by side and find out which kind was best suited to +that state. + + +SECTION XXIII. BUDDING + +If, instead of an apple tree, you were raising a plum or a peach tree, a +form of propagation known as _budding_ would be better than grafting. +Occasionally budding is also employed for apples, pears, cherries, +oranges, and lemons. Budding is done in the following manner. A single +bud is cut from the scion and is then inserted under the bark of a +one-year-old peach seedling, so that the cambium of the bud and stock +may grow together. + +[Illustration: FIG. 69. HOW TO CUT A BUD FROM A SCION] + +[Illustration: FIG. 70. THE STEPS IN BUDDING] + +Cut scions of the kind of fruit tree you desire from a one-year-old twig +of the same variety. Wrap them in a clean, moist cloth until you are +ready to use them. Just before using cut the bud from the scion, as +shown in Fig. 69. This bud is now ready to be inserted on the north side +of the stock, just two or three inches above the ground. The north side +is selected to avoid the sun. Now, as shown at _a_ in Fig. 70, make a +cross and an up-and-down incision, or cut, on the stock; pull the bark +back carefully, as shown in _B_; insert the bud _C_, as shown in _D_; +then fold the bark back and wrap with yarn or raffia, as shown in _E_. +As soon as the bud and branches have united, remove the wrapping to +prevent its cutting the bark and cut the tree back close to the bud, as +in Fig. 71, so as to force nourishment into the inserted bud. + +[Illustration: FIG. 71. +Sloping line shows where to cut tree] + +Budding is done in the field without disturbing the tree as it stands in +the ground. The best time to do budding is during the summer or fall +months, when the bark is loose enough to allow the buds to be easily +inserted. + +Trees may be budded or grafted on one another only when they are nearly +related. Thus the apple, crab-apple, hawthorn, and quince are all +related closely enough to graft or bud on one another; the pear grows on +some hawthorns, but not well on an apple; some chestnuts will unite with +some kinds of oaks. + +[Illustration: FIG. 72. +Lines show where to trim] + +By using any of these methods you can succeed in getting with certainty +the kind of tree that you desire. + +[Illustration: BOTH BUSY STORING APPLES] + + +SECTION XXIV. PLANTING AND PRUNING + +The apple tree that you grafted should be set out in the spring. Dig a +hole three or four feet in diameter where you wish the tree to grow. +Place the tree in the hole and be very careful to preserve all the fine +roots. Spread the roots out fully, water them, and pack fine, rich soil +firmly about them. Place stakes about the young tree to protect it from +injury. If the spot selected is in a windy location, incline the tree +slightly toward the prevailing wind. + +[Illustration: FIG. 73. +Present shape comes from pruning] + +[Illustration: FIG. 74. +Correct shape] + +You must prune the tree as it grows. The object of pruning is to give +the tree proper shape and to promote fruit-bearing. If the bud at the +end of the main shoot grows, you will have a tall, cone-shaped tree. If, +however, the end of the young tree be cut or "headed back" to the lines +shown in Fig. 72, the buds below this point will be forced to grow and +make a tree like that shown in Fig. 73. The proper height of heading for +different fruits varies. For the apple tree a height of two or three +feet is best. + +Cutting an end bud of a shoot or branch always sends the nourishment and +growth into the side buds. Trimming or pinching off the side buds throws +the growth into the end bud. You can therefore cause your tree to take +almost any shape you desire. The difference between the trees shown in +Figs. 73 and 74 is entirely the result of pruning. Fig. 74 illustrates +in general a correctly shaped tree. It is evenly balanced, admits light +freely, and yet has enough foliage to prevent sun-scald. Figs. 75 and 76 +show the effect of wisely thinning the branches. + +[Illustration: FIG. 75. +Unthinned] + +[Illustration: FIG. 76. +Properly thinned] + +The best time to prune is either in the winter or before the buds start +in the spring. Winter pruning tends to favor wood-production, while +summer pruning lessens wood-production and induces fruitage. + +Each particular kind of fruit requires special pruning; for example, the +peach should be made to assume the shape illustrated in Fig. 77. This is +done by successive trimmings, following the plan illustrated in Figs. +71, 78, 79. You will gain several advantages from these trimmings. +First, nourishment will be forced into the peach bud that you set on +your stock. This will secure a vigorous growth of the scion. By a second +trimming take off the "heel" (Fig. 78, _h_) close to the tree, and thus +prevent decay at this point. One year after budding you should reduce +the tree to a "whip," as in Fig. 79, by trimming at the dotted line in +Fig. 78. This establishes the "head" of the tree, which in the case of +the peach should be very low,--about sixteen inches from the ground,--in +order that a low foliage may lessen the danger of sun-scald to the main +trunk. + +[Illustration: FIG. 77. THE CUSTOMARY WAY OF PRUNING A PEACH] + +[Illustration: FIG. 78. TWO-YEAR-OLD TREE +Cut off heel, _h_] + + +In pruning never leave a stump such as is shown in Fig. 78, _h_. Such a +stump, having no source of nourishment, will heal very slowly and with +great danger of decay. If this heel is cleanly cut on the line _ch_ +(Fig. 78), the wound will heal rapidly and with little danger of decay. +Leaving such a stump endangers the soundness of the whole tree. Fig. 80 +shows the results of good and poor pruning on a large tree. When large +limbs are removed it is best to paint the cut surface. The paint will +ward off fungous disease and thus keep the tree from rotting where it +was cut. + +Pruning that leaves large limbs branching, as in Fig. 74, _a_, is not to +be recommended, since the limbs when loaded with fruit or when beaten by +heavy winds are liable to break. Decay is apt to set in at the point of +breakage. The entrance of decay-fungi through some such wound or through +a tiny crevice at such a crotch is the beginning of the end of many a +fruitful tree. + +[Illustration: FIG. 79. THREE-YEAR-OLD TREE CUT BACK] + +Sometimes a tree will go too much to wood and too little to fruit. This +often happens in rich soil and may be remedied by another kind of +pruning known as _root-pruning_. This consists in cutting off a few of +the roots in order to limit the food supply of the plant. You ought to +learn more about root-pruning, however, before you attempt it. + +[Illustration: FIG. 80. +Refuses to Heal--Heals promptly] + +How is a peach tree made? First, the blossom appears. Then pollination +and fertilization occur. The fruit ripens. The pit, or seed, is saved. +In the spring of the next year the seed is planted. The young tree, +known as the stock, comes up quickly. In August of that year a bud of +the variety which is wanted is inserted in the little stock, near the +ground. One year later, in the spring, the stock is cut off just above +the bud. The bud throws out a shoot, which grows to a height of about +six feet, and in the fall this little peach tree is sold as a +one-year-old tree. However, as is seen, the root is two years old. + +[Illustration: FIG. 81. READY TO BEAR] + +How is an apple tree made? The seeds are saved in the fall of one year +and planted the following year. The seedlings of the apple do not grow +so rapidly as those of the peach. At the end of the year they are taken +up and sorted, and in the following spring they are planted. In July or +August they are budded. In the spring of the next year the stock is cut +off above the bud, and the bud-shoot grows three or four feet. One year +later the shoot branches and the top begins to form; and in the fall of +the following year the tree may be sold as a two-year-old, although most +persons prefer to buy it a year later as a three-year-old. In some parts +of the country, particularly in the West, the little seedling is grafted +in the second winter, in a grafting room, and the young grafts are set +in the nursery row in the spring to complete their growth. + +The planting in the orchard of the young peach and the young apple tree +is done in practically the same way. After the hole for the tree has +been dug and after proper soil has been provided, the roots should be +spread and the soil carefully packed around them. + + + =EXERCISE= + + Do you know any trees in your neighborhood that bear both wild and + budded or grafted fruit? What are the chief varieties of apples + grown in your neighborhood? grapes? currants? plums? cherries? + figs? What is a good apple tree worth? Is there any land near by + that could support a tree and is not now doing so? Examine several + orchards and see whether the trees have the proper shape. Do you + see any evidence of poor pruning? Do you find any heels? Can you + see any place where heels have resulted in rotten or hollow trees? + How could you have prevented this? Has the removal of branches ever + resulted in serious decay? How is this to be prevented? + + If your home is not well stocked with all the principal kinds of + fruit, do you not want to propagate and attend to some of each + kind? You will be surprised to find how quickly trees will bear and + how soon you will be eating fruit from your own planting. Growing + your own trees will make you feel proud of your skill. + + + + +CHAPTER V + +HORTICULTURE + + +SECTION XXV. MARKET-GARDENING + +The word _horticulture_ is one of those broad words under which much is +grouped. It includes the cultivation of orchard fruits, such as apples +and plums; of small fruits, such as strawberries and raspberries; of +garden vegetables for the table; of flowers of all sorts, including +shrubbery and ornamental trees and their arrangement into beautiful +landscape effects around our homes. Horticulture then is a name for an +art that is both far-reaching and important. + +The word _gardening_ is generally given to that part of horticulture +which has for its chief aim the raising of vegetables for our tables. + +Flower-gardening, or the cultivation of plants valued for their bloom in +making ornamental beds and borders and furnishing flowers for the +decoration of the home, is generally called _floriculture_. +Landscape-gardening is the art of so arranging flower-beds, grass, +shrubbery, and trees as to produce pleasing effects in the grounds +surrounding our homes and in great public parks and pleasure grounds. + +Landscape-gardening, like architecture, has developed intoll as the +artist makes them on canvas, but uses natural objects in his pictures +instead of paint and canvas. + +=Market-Gardening.= Formerly market-gardening was done on small tracts +of land in the immediate vicinity of large cities, where supplies of +stable manure could be used from the city stables. But with the great +increase in the population of the cities, these small areas could no +longer supply the demand, and the introduction of commercial fertilizers +and the building of railroads enabled gardeners at great distances from +city markets to grow and ship their products. Hence the markets, even in +winter, are now supplied with fresh vegetables from regions where there +is no frost. Then, as spring opens, fruits and vegetables are shipped +from more temperate regions. Later vegetables and fruits come from the +sections nearer the great cities. This gradual nearing of the supply +fields continues until the gardens near the cities can furnish what is +needed. + +[Illustration: FIG. 82. STRAWBERRY-GROWING IS AN ART] + +The market-gardeners around the great Northern cities, finding that +winter products were coming from the South and from warmer regions, +began to build hothouses and by means of steam and hot-water pipes to +make warm climates in these glass houses. Many acres of land in the +colder sections of the country are covered with heated glass houses, and +in them during the winter are produced fine crops of tomatoes, lettuce, +radishes, cauliflowers, eggplants, and other vegetables. The degree of +perfection which these attain in spite of having such artificial +culture, and their freshness as compared to the products brought from a +great distance, have made winter gardening under glass a very profitable +business. But it is a business that calls for the highest skill and the +closest attention. + +[Illustration: FIG. 83. SETTING PLANTS IN A COLD-FRAME] + +No garden, even for home use, is complete without some glass sashes, and +the garden will be all the more successful if there is a small heated +greenhouse for starting plants that are afterwards to be set in the +garden. + +=Hotbeds.= If there is no greenhouse, a hotbed is an important help in +the garden. The bed is made by digging a pit two feet deep, seven feet +wide, and as long as necessary. + +The material for the hotbed is fresh horse manure mixed with leaves. +This is thrown into a heap to heat. As soon as steam is seen coming from +the heap the manure is turned over and piled again so that the outer +part is thrown inside. When the whole is uniformly heated and has been +turned two or three times, it is packed firmly into the pit already dug. + +A frame six feet wide, twelve inches high on the north side and eight +inches on the south side and as long as the bed is to be, is now made of +plank. This is set upon the heated manure, thus leaving six inches on +each side outside the frame. More manure is then banked all around it, +and three or four inches of fine light and rich soil are placed inside +the frame. + +[Illustration: FIG. 84. THE GLADIOLUS] + +The frame is then covered with hotbed sashes six feet long and three +feet wide. These slide up and down on strips of wood let into the sides +of the frame. A thermometer is stuck into the soil and closely watched, +for there will be too much heat at first for sowing seed. When the heat +in the early morning is about 85°, seeds may be sowed. The hotbed is +used for starting tomato plants, eggplants, cabbage plants, and other +vegetables that cannot stand exposure. It should be made about eight or +ten weeks before the tender plants can be set out in the locality. In +the South and Southwest it should be started earlier than in the North. +For growing the best tomato plants, and for such hardy plants as lettuce +and cabbage, it will be better to have cold-frames in addition to the +hotbed; these need not be more than two or three sashes. + +=Cold-Frames.= A cold-frame is like the frame used for a hotbed, but it +is placed on well-manured soil in a sheltered spot. It is covered with +the same kind of sashes and is used for hardening the plants sowed in +the hotbed. The frame must be well banked with earth on the outside, and +the glass must be covered on cold nights with straw, mats, or old +carpets to keep out frost. + +[Illustration: FIG. 85. FRAME TO CARRY THE SASH OF A HOTBED OR COLD-FRAME] + +=Care of Hotbed and Cold-Frame.= If the sun be allowed to shine brightly +on the glass of a cold-frame or hotbed, it will soon raise the +temperature in the hotbed to a point that will destroy the plants. It is +necessary, then, to pay close attention to the bed and, when the sun +shines, to slip the sashes down or raise them and place a block under +the upper end to allow the steam to pass off. The cold-frame also must +be aired when the sun shines, and the sashes must be gradually slipped +down in mild weather. Finally, they may be removed entirely on sunshiny +days, so as to accustom the plants to the open air, but they must be +replaced at night. For a while before setting the plants in the open +gardens, leave the sashes off night and day. + +[Illustration: FIG. 86. GREENHOUSE AND COLD-FRAMES] + +While the hotbed may be used for starting plants, it is much better and +more convenient to have a little greenhouse with fire heat for this +purpose. A little house with but four sashes on each side will be enough +to start a great many plants, and will also give room for some flowers +in pots. With such a house a student can learn to manage a more +extensive structure if he gives close attention to airing, watering, and +keeping out insects. + +=Sowing.= The time for sowing the different kinds of seeds is an +important matter. Seeds vary greatly in their requirements. All need +three conditions--a proper degree of heat, moisture, and air. Some +seeds, like English peas, parsnips, beets, and radishes, will germinate +and grow when the soil is still cool in the early spring, and peas will +stand quite a frost after they are up. Therefore we plant English peas +as early as the ground can be worked. + +But if we should plant seeds like corn, string (or snap) beans, +squashes, and other tender plants before the ground is warm enough, they +would decay. + +Seeds cannot germinate in soil that is perfectly dry, for there must be +moisture to swell them and to start growth. The oxygen of the air is +also necessary, and if seeds are buried so deeply that the air cannot +reach them, they will not grow, even if they are warm and moist. + +[Illustration: FIG. 87. GATHERING AND SHIPPING CELERY] + +The depth of planting must vary with the character and size of the seed. +English peas may be covered six inches deep and will be all the better +for such covering, but if corn be covered so deep, it hardly gets above +the ground. In planting small seeds like those of the radish, cabbage, +turnip, lettuce, etc., a good rule is to cover them three times the +thickness of the seed. + +In sowing seeds when the ground is rather dry, it is a good plan, after +covering them, to tramp on the row so as to press the soil closely to +the seeds and to help it to retain moisture for germination, but do not +pack the soil if it is damp. + +In spring never dig or plow the garden while it is still wet, but always +wait until the soil is dry enough to crumble freely. + +=What Crops to grow.= The crops to be raised will of course depend upon +each gardener's climate, surroundings, and markets. Sometimes it may pay +a grower, if his soil and climate are particularly suited to one crop, +to expend most of his time and energy on this crop; for example, in some +sections of New York, on potatoes; in parts of Michigan, on celery; in +Georgia, on watermelons; in western North Carolina, on cabbage. If +circumstances allow this sort of gardening, it has many advantages, for +of course it is much easier to acquire skill in growing one crop than in +growing many. + +[Illustration: FIG. 88. A LARGE YIELD OF CABBAGES] + +On the other hand, it often happens that a gardener's situation requires +him to grow most of the crops known to gardening. Each gardener then +must be guided in his selection of crops by his surroundings. + +=Care of Crops.= The gardener who wishes to attain the greatest success +in his art must do four things: + +First, he must make his land rich and keep it rich. Much of his success +depends on getting his crops on the market ahead of other growers. To do +this, his crops must grow rapidly, and crops grow rapidly only in rich +soil. Then, too, land conveniently situated for market-gardening is +nearly always costly. Hence the successful market-gardener must plan to +secure the largest possible yield from as small an area as is +practicable. The largest yield can of course be secured from the richest +land. + +Second, the gardener must cultivate his rich land most carefully and +economically. He crowds his land with products that must grow apace. +Therefore he, least of all growers, can afford to have any of his soil +go to feed weeds, to have his land wash, or to have his growing crops +suffer for lack of timely and wise cultivation. To cultivate his land +economically the gardener must use the best tools and machines and the +best methods of soil management. + +Third, to get the best results he must grow perfect vegetables. To do +this, he must add to good tillage a knowledge of the common plant +diseases and of the ways of insects and bacterial pests; he must know +how and when to spray, how and when to treat his seed, how and when to +poison, how and when to trap his insect foes and to destroy their +hiding-places. + +Fourth, not only must the gardener grow perfect vegetables, but he must +put them on the market in perfect condition and in attractive shape. Who +cares to buy wilted, bruised, spoiling vegetables? Gathering, bundling, +crating, and shipping are all to be watched carefully. Baskets should be +neat and attractive, crates clean and snug, barrels well packed and well +headed. Careful attention to all these details brings a rich return. + +Among the gardener's important crops are the following: + +=Asparagus.= This is a hardy plant. Its seed may be sowed either early +in the spring or late in the fall. The seeds should be planted in rows. +If the plants are well cultivated during the spring and summer, they +will make vigorous roots for transplanting in the autumn. + +In the fall prepare a piece of land by breaking it unusually deep and by +manuring it heavily. After the land is thoroughly prepared, make in it +furrows for the asparagus roots. These furrows should be six inches deep +and three feet apart. Then remove the roots from the rows in which they +have been growing during the summer, and set them two feet apart in the +prepared furrows. Cover carefully at once. + +[Illustration: FIG. 89. A CRATE OF ASPARAGUS] + +In the following spring the young shoots must be well cultivated. In +order to economize space, beets or lettuce may be grown between the +asparagus rows during this first season. With the coming of cold weather +the asparagus must again be freely manured and all dead tops cut off. +Some plants will be ready for market the second spring. If the bed is +kept free from weeds and well manured, it will increase in +productiveness from year to year. + +=Beans.= The most generally planted beans are those known as string, or +snap, beans. Of the many varieties, all are sensitive to cold and hence +must not be planted until frost is over. + +Another widely grown kind of bean is the lima, or butter, bean. There +are two varieties of the lima bean. One is large and generally grows on +poles. This kind does best in the Northern states. The other is a small +bean and may be grown without poles. This kind is best suited to the +warmer climates of the Southern states. + +=Cabbage.= In comparatively warm climates the first crop of cabbage is +generally grown in the following way. The seeds are sowed in beds in +September, and the plants grown from this sowing are in November +transplanted to ground laid off in sharp ridges. The young plants are +set on the south side of the ridges in order that they may be somewhat +protected from the cold of winter. As spring comes on, the ridge is +partly cut down at each working until the field is leveled, and +thereafter the cultivation should be level. + +[Illustration: FIG. 90. CABBAGE READY FOR SHIPMENT] + +Early cabbages need heavy applications of manure. In the spring, nitrate +of soda applied in the rows is very helpful. + +Seeds for the crop following this early crop should be sowed in March. +Of course these seeds should be of a later variety than the first used. +The young plants should be transplanted as soon as they are large +enough. Early cabbages are set in rows three feet apart, the plants +eighteen inches apart in the row. As the later varieties grow larger +than the earlier ones, the plants should be set two feet apart in the +row. + +In growing late fall and winter cabbage the time of sowing varies with +the climate. For the Northern and middle states, seeding should be done +during the last of March and in April. South of a line passing west from +Virginia it is hard to carry cabbages through the heat of summer and get +them to head in the fall. However, if the seeds are sowed about the +first of August in rich and moist soil and the plants set in the same +sort of soil in September, large heads can be secured for the December +market. + +[Illustration: FIG. 91. CELERY TRIMMED, WASHED, AND BUNCHED] + +=Celery.= In the extreme northern part of our country, celery seeds are +often sowed in a greenhouse or hotbed. This is done in order to secure +plants early enough for summer blanching. This plan, however, suits only +very cool climates. + +In the middle states the seeds are usually sowed in a well-prepared bed +about April. The young plants are moved to other beds as soon as they +need room. Generally they are transplanted in July to rows prepared for +them. These should be four feet apart, and the plants should be set six +inches apart in the row. The celery bed should be carefully cultivated +during the summer. In the fall, hill the stalks up enough to keep them +erect. After the growing season is over dig them and set them in +trenches. The trenches should be as deep as the celery is tall, and +after the celery is put in them they should be covered with boards and +straw. + +In the more southern states, celery is usually grown in beds. The beds +are generally made six feet wide, and rows a foot apart are run +crosswise. The plants are set six inches apart, in September, and the +whole bed is earthed up as the season advances. Finally, when winter +comes the beds are covered with leaves or straw to prevent the plants +from freezing. The celery is dug and bunched for market at any time +during the winter. + +By means of cold-frames a profitable crop of spring celery may be +raised. Have the plants ready to go into the cold-frames late in October +or early in November. The soil in the frame should be made very deep. +The plants should make only a moderately rapid growth during the winter. +In the early spring they will grow rapidly and so crowd one another as +to blanch well. As celery grown in this way comes on the market at a +time when no other celery can be had, it commands a good price. + +In climates as warm as that of Florida, beds of celery can be raised in +this way without the protection of cold-frames. A slight freeze does not +hurt celery, but a long-continued freezing spell will destroy it. + +Some kinds of celery seem to turn white naturally. These are called +self-blanching kinds. Other kinds need to be banked with earth in order +to make the stalks whiten. This kind usually gives the best and crispest +stalks. + +=Cucumbers and Cantaloupes.= Although cucumbers and cantaloupes are very +different plants, they are grown in precisely the same way. Some +gardeners plant them in hills. However, this is perhaps not the best +plan. It is better to lay the land off in furrows six feet apart. After +filling these with well-rotted stable manure, throw soil over them. Then +make the top flat and plant the seeds. After the plants are up thin them +out, leaving them a foot or more apart in the rows. Cultivate regularly +and carefully until the vines cover the entire ground. + +It is a good plan to sow cowpeas at the last working of cantaloupes, in +order to furnish some shade for the melons. As both cucumbers and +cantaloupes are easily hurt by cold, they should not be planted until +the soil is warm and all danger of frost is past. + +Cucumbers are always cut while they are green. They should never be +pulled from the vine, but should always be cut with a piece of the stem +attached. Cantaloupes should be gathered before they turn yellow and +should be ripened in the house. + +[Illustration: FIG. 92. STRIPED CUCUMBER BEETLE AND LARVA +All magnified] + +In some sections of the country the little striped cucumber-beetle +attacks the melons and cucumbers as soon as they come up. These beetles +are very active, and if their attacks are not prevented they will +destroy the tender plants. Bone dust and tobacco dust applied just as +the plants appear above the ground will prevent these attacks. This +treatment not only keeps off the beetle, but also helps the growth of +the plants. + +=Eggplants.= Eggplants are so tender that they cannot be transplanted +like tomatoes to cold-frames and gradually hardened to stand the cold +spring air. These plants, started in a warm place, must be kept there +until the soil to which they are to be transplanted is well warmed by +the advance of spring. After the warm weather has fully set in, +transplant them to rich soil, setting them three feet apart each way. +This plant needs much manure. If large, perfect fruit is expected, the +ground can hardly be made too rich. + +Eggplants are subject to the same bacterial blight that is so +destructive to tomatoes. The only way to prevent this disease is to +plant in ground not lately used for tomatoes or potatoes. + +[Illustration: FIG. 93. AN ONION HARVEST] + +=Onions.= The method of growing onions varies with the use to which it +is intended to put them. To make the early sorts, which are eaten green +in the spring, little onions called _sets_ are planted. These are grown +from seeds sowed late in the spring. The seeds are sowed thickly in rows +in rather poor land. The object of selecting poor land is that the +growth of the sets may be slow. When the sets have reached the size of +small marbles, they are ready for the fall planting. + +In the South the sets may be planted in September. Plant them in rows in +rich and well-fertilized soil. They will be ready for market in March +or April. In the more northerly states the sets are to be planted as +early as possible in the spring. + +To grow ripe onions the seeds must be sowed as early in the spring as +the ground can be worked. The plants are thinned to a stand of three +inches in the rows. As they grow, the soil is drawn away from them so +that the onions sit on top of the soil with only their roots in the +earth. + +[Illustration: FIG. 94. HOTBED FOR STARTING TOMATO PLANTS] + +As soon as the tops ripen pull the onions and let them lie in the sun +until the tops are dry. Then put them under shelter. As onions keep best +with their tops attached, do not remove these until it is time for +marketing. + +=Peas.= The English pea is about the first vegetable of the season to be +planted. It may be planted as soon as the ground is in workable +condition. Peas are planted in rows, and it is a good plan to stretch +wire netting for them to climb on. However, where peas are extensively +cultivated they are allowed to fall on the ground. + +There are many sorts of peas, differing both in quality and in time of +production. The first to be planted are the extra-early varieties. These +are not so fine as the later, wrinkled sorts, but the seeds are less apt +to rot in cold ground. Following these, some of the fine, wrinkled sorts +are to be planted in regular succession. Peas do not need much manure +and do best in a light, warm soil. + +=Tomatoes.= There is no vegetable grown that is more widely used than +the tomato. Whether fresh or canned it is a staple article of food that +can be served in many ways. + +By careful selection and breeding, the fruit of the tomato has in recent +years been much improved. There are now many varieties that produce +perfectly smooth and solid fruit, and the grower can hardly go amiss in +his selection of seeds if he bears his climate and his particular needs +in mind. + +Early tomatoes are started in the greenhouse or in the hotbed about ten +weeks before the time for setting the plants in the open ground. They +are transplanted to cold-frames as soon as they are large enough to +handle. This is done to harden the plants and to give them room to grow +strong before the final transplanting. + +In kitchen gardens tomatoes are planted in rows four feet apart with the +plants two feet apart in the rows. They are generally trained to stakes +with but one stalk to a stake. When there is plenty of space, however, +the plants are allowed to grow at will and to tumble on the ground. In +this way they bear large crops. During the winter the markets are +supplied with tomatoes either from tropical sections or from hothouses. +As those grown in the hothouses are superior in flavor to those shipped +from Florida and from the West Indies, and as they command good prices, +great quantities are grown in this way. + +In the South the bacterial blight which attacks the plants of this +family is a serious drawback to tomato culture. The only way to escape +this disease is to avoid planting tomatoes on land in which eggplants, +tomatoes, or potatoes have been blighted. Lime spread around the plants +seems to prevent the blight for one season on some soils. + +At the approach of frost in the fall, green tomatoes can easily be +preserved by wrapping them in paper. Gather them carefully and wrap each +separately. Pack them in boxes and store in a cellar that is close +enough to prevent the freezing of the fruit. A few days before the +tomatoes are wanted for the table unpack as many as are needed, remove +the paper, and allow them to ripen in a warm room. + +Tomatoes require a rich soil. Scattering a small quantity of nitrate of +soda around their roots promotes rapid growth. + +=Watermelons.= As watermelons need more room than can usually be spared +in a garden, they are commonly grown as a field crop. + +A very light, sandy soil suits watermelons best. They can be grown on +very poor soil if a good supply of compost be placed in each hill. The +land for the melons should be laid off in about ten-foot checks; that +is, the furrows should cross one another at right angles about every ten +feet. A wide hole should be dug where the furrows cross, and into this +composted manure should be put. + +The best manure for watermelons is a compost of stable manure and +wood-mold from the forest. Pile the manure and wood-mold in alternate +layers for some time before the planting season. During the winter cut +through the pile several times until the two are thoroughly mixed and +finely pulverized. Be sure to keep the compost heap under shelter. +Compost will lose in value if it is exposed to rains. + +At planting-time, put two or three shovelfuls of this compost into each +of the prepared holes, and over the top of the manure scatter a handful +of any high-grade complete fertilizer. Then cover fertilizer and manure +with soil, and plant the seeds in this soil. In cultivating, plow both +ways of the checked rows and throw the earth toward the plants. + +Some growers pinch off the vines when they have grown about three feet +long. This is done to make them branch more freely, but the pinching is +not necessary. + +A serious disease, the watermelon wilt, is rapidly spreading through +melon-growing sections. This disease is caused by germs in the soil, and +the germs are hard to kill. If the wilt should appear in your +neighborhood, do not allow any stable manure to be used on your melon +land, for the germs are easily scattered by means of stable manure. The +germs also cling to the seeds of diseased melons, and these seeds bear +the disease to other fields. If you treat melon seeds as you are +directed on page 135 to treat oat seeds, the germs on the seeds will be +destroyed. By crossing the watermelon on the citron melon, a watermelon +that is resistant to wilt has recently been developed and successfully +grown in soils in which wilt is present. The new melon, inferior in +flavor at first, is being improved from season to season and bids fair +to rival other melons in flavor. + +[Illustration: FIG. 95. DEWBERRIES] + + +SECTION XXVI. FLOWER GARDENING + +The comforts and joys of life depend largely upon small things. Of these +small things perhaps none holds a position of greater importance in +country life than the adornment of the home, indoors and outdoors, with +flowers tastefully arranged. Their selection and planting furnish +pleasant recreation; their care is a pleasing employment; and each +little plant, as it sprouts and grows and develops, may become as much a +pet as creatures of the sister animal kingdom. A beautiful, well-kept +yard adds greatly to the pleasure and attractiveness of a country home. +If a beautiful yard and home give joy to the mere passer-by, how much +more must their beauty appeal to the owners. The decorating of the home +shows ambition, pride, and energy--important elements in a successful +life. + +[Illustration: FIG. 96. AN EASY WAY TO BEAUTIFY THE HOME] + +Plant trees and shrubs in your yard and border your masses of shrubbery +with flower-beds. Do not disfigure a lawn by placing a bed of flowers in +it. Use the flowers rather to decorate the shrubbery, and for borders +along walks, and in the corners near steps, or against foundations. + +If you wish to raise flowers for the sake of flowers, not as +decorations, make the flower-beds in the back yard or at the side of the +house. + +[Illustration: FIG. 97. A BACK YARD TO REFINE THE CHILDREN OF THE +FAMILY] + +Plants may be grown from seeds or from bulbs or from cuttings. The +rooting of cuttings is an interesting task to all who are fond of +flowers. Those who have no greenhouse and who wish to root cuttings of +geraniums, roses, and other plants may do so in the following way. Take +a shallow pan, an old-fashioned milk pan for instance, fill it nearly +full of clean sand, and then wet the sand thoroughly. Stick the cuttings +thickly into this wet sand, set the pan in a warm, sunny window, and +keep the sand in the same water-soaked condition. Most cuttings will +root well in a few weeks and may then be set into small flower-pots. +Cuttings of tea roses should have two or three joints and be taken from +a stem that has just made a flower. Allow one of the rose leaves to +remain at the top of the cutting. Stick this cutting into the sand and +it will root in about four weeks. Cuttings of Cape jasmine may be rooted +in the same way. Some geraniums, the rose geranium for example, may be +grown from cuttings of the roots. + +[Illustration: FIG. 98. REPOTTING] + +Bulbs are simply the lower ends of the leaves of a plant wrapped tightly +around one another and inclosing the bud that makes the future +flower-stalk. The hyacinth, the narcissus, and the common garden onion +are examples of bulbous plants. The flat part at the bottom of the bulb +is the stem of the plant reduced to a flat disk, and between each two +adjacent leaves on this flat stem there is a bud, just as above-ground +there is a bud at the base of a leaf. These buds on the stem of the bulb +rarely grow, however, unless forced to do so artificially. The number +of bulbs may be greatly increased by making these buds grow and form +other bulbs. In increasing hyacinths the matured bulbs are dug in the +spring, and the under part of the flat stem is carefully scraped away to +expose the base of the buds. The bulbs are then put in heaps and covered +with sand. In a few weeks each bud has formed a little bulb. The +gardener plants the whole together to grow one season, after which the +little bulbs are separated and grown into full-sized bulbs for sale. +Other bulbs, like the narcissus or the daffodil, form new bulbs that +separate without being scraped. + +[Illustration: FIG. 99. A CLEMATIS] + +There are some other plants which have underground parts that are +commonly called bulbs but which are not bulbs at all; for example, the +gladiolus and the caladium, or elephant's ear. Their underground parts +are bulblike in shape, but are really solid flattened stems with eyes +like the underground stem of the Irish potato. These parts are called +_corms_. They may be cut into pieces like the potato and each part will +grow. + +The dahlia makes a mass of roots that look greatly like sweet potatoes, +but there are no eyes on them as there are on the sweet potato. The only +eyes are on the base of the stem to which they are joined. They may be +sprouted like sweet potatoes and then soft cuttings made of the green +shoots, after which they may be rooted in the greenhouse and later +planted in pots. + +There are many perennial plants that will bloom the first season when +grown from the seed, though such seedlings are seldom so good as the +plants from which they came. They are generally used to originate new +varieties. Seeds of the dahlia, for instance, can be sowed in a box in a +warm room in early March, potted as soon as the plants are large enough +to handle, and finally planted in the garden when the weather is warm. +They will bloom nearly as soon as plants grown by dividing the roots or +from cuttings. + +[Illustration: FIG. 100. OUTDOOR-GROWN CHRYSANTHEMUMS] + +In growing annual plants from seed, there is little difficulty if the +grower has a greenhouse or a hotbed with a glass sash. Even without +these the plants may be grown in shallow boxes in a warm room. The best +boxes are about four inches deep with bottoms made of slats nailed a +quarter of an inch apart to give proper drainage. Some moss is laid over +the bottom to prevent the soil from sifting through. The boxes should +then be filled with light, rich soil. Fine black forest mold, thoroughly +mixed with one fourth its bulk of well-rotted manure, makes the best +soil for filling the seed-boxes. If this soil be placed in an oven and +heated very hot, the heat will destroy many weeds that would otherwise +give trouble. After the soil is put in the boxes it should be well +packed by pressing it with a flat wooden block. Sow the seeds in +straight rows, and at the ends of the rows put little wooden labels with +the names of the flowers on them. + +[Illustration: FIG. 101. THE CARNATION (ELDORADO)] + +Seeds sowed in the same box should be of the same general size in order +that they may be properly covered, for seeds need to be covered +according to their size. After sowing the seed, sift the fine soil over +the surface of the box. The best soil for covering small seeds is made +by rubbing dry moss and leaf-mold through a sieve together. This makes a +light cover that will not bake and will retain moisture. After covering +the seeds, press the soil firm and smooth with a wooden block. Now +sprinkle the covering soil lightly with a watering-pot until it is +fairly moistened. Lay some panes of glass over the box to retain the +moisture, and avoid further watering until moisture becomes absolutely +necessary. Too much watering makes the soil too compact and rots the +seed. + +As soon as the seedlings have made a second pair of leaves, take them up +with the point of a knife and transplant them into other boxes filled in +the same way. They should be set two inches apart so as to give them +room to grow strong. They may be transplanted from the boxes to the +flower-garden by taking an old knife-blade and cutting the earth into +squares, and then lifting the entire square with the plant and setting +it where it is wanted. + +There are many flower-seeds which are so small that they must not be +covered at all. In this class we find begonias, petunias, and Chinese +primroses. To sow these prepare boxes as for the other seeds, and press +the earth smooth. Then scatter some fine, dry moss thinly over the +surface of the soil. Sprinkle this with water until it is well +moistened, and at once scatter the seeds thinly over the surface and +cover the boxes with panes of glass until the seeds germinate. +Transplant as soon as the young plants can be lifted out separately on +the blade of a penknife. + +[Illustration: FIG. 102. THE POET'S NARCISSUS] + +Many kinds of flower-seeds may be sowed directly in the open ground +where they are to remain. The sweet pea is one of the most popular +flowers grown in this way. The seeds should be sowed rather thickly in +rows and covered fully four inches deep. The sowing should be varied in +time according to the climate. From North Carolina southward, sweet peas +may be sowed in the fall or in January, as they are very hardy and +should be forced to bloom before the weather becomes hot. Late spring +sowing will not give fine flowers in the South. From North Carolina +northward the seeds should be sowed just as early in the spring as the +ground can be easily worked. When the plants appear, stakes should be +set along the rows and a strip of woven-wire fence stretched for the +plants to climb on. Morning-glory seeds are also sowed where they are to +grow. The seeds of the moonflower are large and hard and will fail to +grow unless they are slightly cut. To start their growth make a slight +cut just through the hard outer coat of the seed so as to expose the +white inside. In this way they will grow very readily. The seeds of the +canna, or Indian-shot plant, are treated in a similar way to start them +growing. + +[Illustration: FIG. 103. A CYCLAMEN] + +[Illustration: FIG. 104. A MODERN SWEET PEA] + +The canna makes large fleshy roots which in the North are taken up, +covered with damp moss, and stored under the benches of the greenhouse +or in a cellar. If allowed to get too dry, they will wither. From +central North Carolina south it is best to cover them up thickly with +dead leaves and let them stay in the ground where they grew. In the +early spring take them up and divide for replanting. + +[Illustration: FIG. 105. DAHLIAS] + +Perennial plants, such as our flowering shrubs, are grown from cuttings +of the ripe wood after the leaves have fallen in autumn. From North +Carolina southward these cuttings should be set in rows in the fall. +Cuttings ten inches long are set so that the tops are just even with the +ground. A light cover of pine leaves will prevent damage from frost. +Farther north the cuttings should be tied in bundles and well buried in +the ground with earth heaped over them. In the spring set them in rows +for rooting. In the South all the hardy hybrid perpetual roses can be +grown in this way, and in any section the cuttings of most of the +spring-flowering shrubs will grow in the same manner. The Japanese +quince, which makes such a show of its scarlet flowers in early spring, +can be best grown from three-inch cuttings made of the roots and planted +in rows in the fall. + +[Illustration: FIG. 106. FOUR-O'CLOCKS SET IN A GOOD PLACE] + +Many of our ornamental evergreen trees, such as the arbor vitæ, can be +grown in the spring from seeds sowed in a frame. Cotton cloth should be +stretched over the trees while they are young, to prevent the sun from +scorching them. When a year old they may be set in nursery rows to +develop until they are large enough to plant. Arbor vitæ may also be +grown from cuttings made by setting young tips in boxes of sand in the +fall and keeping them warm and moist through the winter. Most of them +will be rooted by spring. + +The kinds of flowers that you can grow are almost countless. You can +hardly make a mistake in selecting, as all are interesting. Start this +year with a few and gradually increase the number under your care year +by year, and aim always to make your plants the choicest of their kind. + +Of annuals there are over four hundred kinds cultivated. You may select +from the following list: phlox, petunias, China asters, California +poppies, sweet peas, pinks, double and single sunflowers, hibiscus, +candytuft, balsams, morning-glories, stocks, nasturtiums, verbenas, +mignonette. + +[Illustration: FIG. 107. A WINDOW BOX] + +Of perennials select bleeding-hearts, pinks, bluebells, hollyhocks, +perennial phlox, perennial hibiscus, wild asters, and goldenrods. From +bulbs choose crocus, tulip, daffodil, narcissus, lily of the valley, and +lily. + +Some climbers are cobæa, honeysuckle, Virginia creeper, English ivy, +Boston ivy, cypress vine, hyacinth bean, climbing nasturtiums, and +roses. + +To make your plants do best, cultivate them carefully. Allow no weeds to +grow among them and do not let the surface of the soil dry into a hard +crust. Beware, however, of stirring the soil too deep. Loosening the +soil about the roots interrupts the feeding of the plant and does harm. +Climbing plants may be trained to advantage on low woven-wire fences. +These are especially serviceable for sweet peas and climbing +nasturtiums. Do not let the plants go to seed, since seeding is a heavy +drain on nourishment. Moreover, the plant has served its end when it +seeds and is ready then to stop blossoming. You should therefore pick +off the old flowers to prevent their developing seeds. This will cause +many plants which would otherwise soon stop blossoming to continue +bearing flowers for a longer period. + +[Illustration: FIG. 108. A WINDOW-GARDEN] + +=Window-Gardening.= Growing plants indoors in the window possesses many +of the attractions of outdoor flower-gardening, and is a means of +beautifying the room at very small expense. Especially do window-gardens +give delight during the barren winter time. They are a source of culture +and pleasure to thousands who cannot afford extended and expensive +ornamentation. + +The window-garden may vary in size from an eggshell holding a minute +plant to boxes filling all the available space about the window. The +soil may be in pots for individual plants or groups of plants or in +boxes for collections of plants. You may raise your flowers inside of +the window on shelves or stands, or you may have a set of shelves built +outside of the window and inclosed in glazed sashes. The illustration on +page 119 gives an idea of such an external window-garden. + +[Illustration: FIG. 109. AN INSIDE WINDOW BOX IN ITS FULL GLORY] + +The soil must be rich and loose. The best contains some undecayed +organic matter such as leaf-mold or partly decayed sods and some sand. +Raise your plants from bulbs, cuttings, or seed, just as in outdoor +gardens. Some plants do better in cool rooms, others in a warmer +temperature. + +[Illustration: FIG. 110. MAKING THE OUTSIDE OF A WINDOW BLOOM] + +If the temperature ranges from 35° to 70°, averaging about 55°, azaleas, +daisies, carnations, candytuft, alyssum, dusty miller, chrysanthemums, +cinerarias, camellias, daphnes, geraniums, petunias, violets, primroses, +and verbenas make especially good growths. + +[Illustration: A BEAUTIFUL WINDOW FLOWER] + +If the temperature is from 50° to 90°, averaging 70°, try abutilon, +begonia, bouvardia, caladium, canna, Cape jasmine, coleus, fuchsia, +gloxinia, heliotrope, lantana, lobelia, roses, and smilax. + +If your box or window is shaded a good part of the time, raise begonias, +camellias, ferns, and Asparagus Sprengeri. + +[Illustration: FIG. 111. FERNS FOR BOTH INDOORS AND OUTDOORS] + +When the soil is dry, water it; then apply no more water until it again +becomes dry. Beware of too much water. The plants should be washed +occasionally with soapsuds and then rinsed. If red spiders are present, +sponge them off with water as hot as can be borne comfortably by the +hand. Newspapers afford a good means of keeping off the cold. + + + + +CHAPTER VI + +THE DISEASES OF PLANTS + + +SECTION XXVII. THE CAUSE AND NATURE OF PLANT DISEASE + +Plants have diseases just as animals do; not the same diseases, to be +sure, but just as serious for the plant. Some of them are so dangerous +that they kill the plant; others partly or wholly destroy its usefulness +or its beauty. Some diseases are found oftenest on very young plants, +others prey on the middle-aged tree, while still others attack merely +the fruit. Whenever a farmer or fruit-grower has disease on his plants, +he is sure to lose much profit. + +You have all seen rotten fruit. This is diseased fruit. Fruit rot is a +plant disease. It costs farmers millions of dollars annually. A +fruit-grower recently lost sixty carloads of peaches in a single year +through rot which could have been largely prevented if he had known how. + +Many of the yellowish or discolored spots on leaves are the result of +disease, as is also the smut of wheat, corn, and oats, the blight of the +pear, and the wilt of cotton. Many of these diseases are contagious, or, +as we often hear said of measles, "catching." This is true, among +others, of the apple and peach rots. A healthy apple can catch this +disease from a sick apple. You often see evidence of this in the apple +bin. So, too, many of the diseases found in the field or garden are +contagious. + +Sometimes when the skin of a rotten apple has been broken you will find +in the broken place a blue mold. It was this that caused the apple to +decay. This mold is a living plant; very small, certainly, but +nevertheless a plant. Let us learn a little about molds, in order that +we may better understand our apple and potato rots, as well as other +plant diseases. + +If you cut a lemon and let it stand for a day or two, there will +probably appear a blue mold like that you have seen on the surface of +canned fruit. Bread also sometimes has this blue mold; at other times +bread has a black mold, and yet again a pink or a yellow mold. + +These and all other molds are tiny living plants. Instead of seeds they +produce many very small bodies that serve the purpose of seeds and +reproduce the mold. These are called _spores_. Fig. 112 shows how they +are borne on the parent plant. + +[Illustration: FIG. 112. TANGLED THREADS OF BLUE MOLD +The single stalk on the left shows how spores are borne] + +It is also of great importance to decide whether by keeping the spores +away we may prevent mold. Possibly this experiment will help us. Moisten +a piece of bread, then dip a match or a pin into the blue mold on a +lemon, and draw the match across the moist bread. You will thus plant +the spores in a row, though they are so small that perhaps you may not +see any of them. Place the bread in a damp place for a few days and +watch it. Does the mold grow where you planted it? Does it grow +elsewhere? This experiment should prove to you that molds are living +things and can be planted. If you find spots elsewhere, you must bear in +mind that these spores are very small and light and that some of them +were probably blown about when you made your sowing. When you touch the +moldy portion of a dry lemon, you see a cloud of dust rise. This dust is +made of millions of spores. + +[Illustration: FIG. 113. MAGNIFIED ROSE MILDEW] + +If you plant many other kinds of mold you will find that the molds come +true to the kind that is planted; that like produces like even among +molds. + +[Illustration: FIG. 114. A MILDEWED ROSE] + +You can prove, also, that the mold is caused only by other mold. To do +this, put some wet bread in a wide-mouthed bottle and plug the mouth of +the bottle with cotton. Kill all the spores that may be in this bottle +by steaming it an hour in a cooking-steamer. This bread will not mold +until you allow live mold from the outside to enter. If, however, at any +time you open the bottle and allow spores to enter, or if you plant +spores therein, and if there be moisture enough, mold will immediately +set in. + +[Illustration: FIG. 115. A HIGHLY MAGNIFIED SECTION OF DISEASED PEAR LEAF +Showing how spores are borne] + +The little plants which make up these molds are called _fungi_. Some +fungi, such as the toadstools, puffballs, and devil's snuff-box, are +quite large; others, namely the molds, are very small; and others are +even smaller than the molds. Fungi never have the green color of +ordinary plants, always reproduce by spores, and feed on living matter +or matter that was once alive. Puffballs, for example, are found on +rotting wood or dead twigs or roots. Some fungi grow on living plants, +and these produce plant disease by taking their nourishment from the +plant on which they grow; the latter plant is called the _host_. + +The same blue mold that grows on bread often attacks apples that have +been slightly bruised; it cannot pierce healthy apple skin. You can +plant the mold in the bruised apple just as you did on bread and watch +its rapid spread through the apple. You learn from this the need of +preventing bruised or decayed apples from coming in contact with healthy +fruit. + +[Illustration: FIG. 116. SPORES OF THE PEAR SCAB +The spores are borne on stalks] + +Just as the fungus studied above lives in the apple or bread, so other +varieties live on leaves, bark, etc. Fig. 113 represents the surface of +a mildewed rose leaf greatly magnified. This mildew is a fungus. You can +see its creeping stems, its upright stalk, and numerous spores ready to +fall off and spread the disease with the first breath of wind. You must +remember that this figure is greatly magnified, and that the whole +portion shown in the figure is only about one tenth of an inch across. +Fig. 114 shows the general appearance of a twig affected by this +disease. + +Mildew on the rose or on any other plant may be killed by spraying the +leaves with a solution of liver of sulphur; to make this solution, use +one ounce of the liver of sulphur to two gallons of water. + +The fungus that causes the pear-leaf spots has its spores in little pits +(Fig. 115). The spores of some fungi also grow on stalks, as shown in +Fig. 116. This figure represents an enlarged view of the pear scab, +which causes so much destruction. + +You see, then, that fungi are living plants that grow at the expense of +other plants and cause disease. Now if you can cover the leaf with a +poison that will kill the spore when it comes, you can prevent the +disease. One such poison is the Bordeaux (_bôr-do_') mixture, which +has proved of great value to farmers. + +Since the fungus in most cases lives within the leaves, the poison on +the outside does no good after the fungus is established. The treatment +can be used only to _prevent_ attack, not to cure, except in the case of +a few mildews that live on the outside of the leaf, as does the rose +mildew. + + + =EXERCISE= + + Why do things mold more readily in damp places? Do you now + understand why fruit is heated before it is canned? Try to grow + several kinds of mold. Do you know any fungi which may be eaten? + + Transfer disease from a rotten apple to a healthy one and note the + rapidity of decay. How many really healthy leaves can you find on a + strawberry plant? Do you find any spots with reddish borders and + white centers? Do you know that this is a serious disease of the + strawberry? What damage does fruit mold do to peaches, plums, or + strawberries? + + Write to your experiment station for bulletins on plant diseases + and methods for making and using spraying mixtures. + + +SECTION XXVIII. YEAST AND BACTERIA + +Can you imagine a plant so small that it would take one hundred plants +lying side by side to equal the thickness of a sheet of writing-paper? +There are plants that are so small. Moreover, these same plants are of +the utmost importance to man. Some of them do him great injury, while +others aid him very much. + +You will see their importance when you are told that certain of them in +their habits of life cause great change in the substances in which they +live. For example, when living in a sugary substance they change the +sugar into a gas and an alcohol. Do you remember the bright bubbles of +gas you have seen rising in sweet cider or in wine as it soured? These +bubbles are caused by one of these small plants--the yeast plant. As the +yeast plant grows in the sweet fruit juice, alcohol is made and a gas is +given off at the same time, and this gas makes the bubbles. + +[Illustration: FIG. 117. YEAST PLANTS +_A_, a single plant; _B_, group of two budding cells; _C_, group of +several cells] + +Later, other kinds of plants equally small will grow and change the +alcohol into an acid which you will recognize as vinegar by its sour +taste and peculiar odor. Thus vinegar is made by the action of two +different kinds of little living plants in the cider. That these are +living beings you can prove by heating the cider and keeping it tightly +sealed so that nothing can enter it. You will find that because the +living germs have been killed by the heat, the cider will not ferment or +sour as it did before. The germs could of course be killed by poisons, +but then the cider would be unfit for use. It is this same little yeast +plant that causes bread to rise. + +When you see any decaying matter you may know that in it minute plants +much like the yeast plant are at work. Since decay is due to them, we +take advantage of the fact that they cannot grow in strong brine or +smoke; and we prepare meat for keeping by salting it or by smoking it or +by both of these methods. + +You see that some of the yeast plants and _bacteria_, as many of these +forms are called, are very friendly to us, while others do us great +harm. + +Some bacteria grow within the bodies of men and other animals or in +plants. When they do so they may produce disease. Typhoid fever, +diphtheria, consumption, and many other serious diseases are caused by +bacteria. Fig. 118, _e_, shows the bacterium that causes typhoid fever. +In the picture, of course, it is very greatly magnified. In reality +these bacteria are so small that about twenty-five thousand of them side +by side would extend only one inch. These small beings produce their +great effects by very rapid multiplication and by giving off powerful +poisons. + +[Illustration: FIG. 118. FORMS OF BACTERIA +_a_, grippe; _b_, bubonic plague; _c_, diphtheria; _d_, tuberculosis; +_e_, typhoid fever] + +Bacteria are so small that they are readily borne on the dust particles +of the air and are often taken into the body through the breath and also +through water or milk. You can therefore see how careful you should be +to prevent germs from getting into the air or into water or milk when +there is disease about your home. You should heed carefully all +instructions of your physician on this point, so that you may not spread +disease. + + +SECTION XXIX. PREVENTION OF PLANT DISEASE + +In the last two sections you have learned something of the nature of +those fungi and bacteria that cause disease in animals and plants. Now +let us see how we can use this knowledge to lessen the diseases of our +crops. Farmers lose through plant diseases much that could be saved by +proper precaution. + +First, you must remember that every diseased fruit, twig, or leaf bears +millions of spores. These must be destroyed by burning. They must not be +allowed to lie about and spread the disease in the spring. See that +decayed fruit in the bin or on the trees is destroyed in the same +manner. Never throw decayed fruit into the garden or orchard, as it may +cause disease the following year. + +Second, you can often kill spores on seeds before they are planted and +thus prevent the development of the fungus (see pp. 134-137). + +Third, often the foliage of the plant can be sprayed with a poison that +will prevent the germination of the spores (see pp. 138-140). + +Fourth, some varieties of plants resist disease much more stoutly than +others. We may often select the resistant form to great advantage (see +Fig. 119). + +Fifth, after big limbs are pruned off, decay often sets in at the wound. +This decay may be prevented by coating the cut surface with paint, tar, +or some other substance that will not allow spores to enter the wound or +to germinate there. + +Sixth, it frequently happens that the spore or fungus remains in the +soil. This is true in the cotton wilt, and the remedy is so to rotate +crops that the diseased land is not used again for this crop until the +spores or fungi have died. + + +SECTION XXX. SOME SPECIAL PLANT DISEASES + +=Fire-Blight of the Pear and Apple.= You have perhaps heard your father +speak of the "fire-blight" of pear and apple trees. This is one of the +most injurious and most widely known of fruit diseases. Do you want to +know the cause of this disease and how to prevent it? + +First, how will you recognize this disease? If the diseased bough at +which you are looking has true fire-blight, you will see a blackened +twig with withered, blackened leaves. During winter the leaves do not +fall from blighted twigs as they do from healthy ones. The leaves wither +because of the diseased twig, not because they are themselves diseased. +Only rarely does the blight really enter the leaf. Sometimes a sharp +line separates the blighted from the healthy part of the twig. + +This disease is caused by bacteria, of which you have read in another +section. The fire-blight bacteria grow in the juicy part of the stem, +between the wood and the bark. This tender, fresh layer (as explained on +page 79) is called the _cambium_, and is the part that breaks away and +allows you to slip the bark off when you make your bark whistle in the +spring. The growth of new wood takes place in the cambium, and this part +of the twig is therefore full of nourishment. If this nourishment is +stolen the plant of course soon suffers. + +The bacteria causing fire-blight are readily carried from flower to +flower and from twig to twig by insects; therefore to keep these and +other bacteria away from your trees you must see to it that all the +trees in the neighborhood of your orchard are kept free from mischievous +enemies. If harmful bacteria exist in near-by trees, insects will carry +them to your orchard. You must therefore watch all the relatives of the +pear; namely, the apple, hawthorn, crab, quince, and mountain ash, for +any of these trees may harbor the germs. + +[Illustration: FIG. 119. A RESISTANT VARIETY OF SEA ISLAND COTTON +All the other plants in this field died. This one row lived because it +could resist the cotton wilt] + +When any tree shows blight, every diseased twig on it must be cut off +and burned in order to kill the germs, and you must cut low enough on +the twig to get all the bacteria. It is best to cut a foot below the +blackened portion. If by chance your knife should cut into wood +containing the living germs, and then you should cut into healthy wood +with the same knife, you yourself would spread the disease. It is +therefore best after each cutting to dip your knife into a solution of +carbolic acid. This will kill all bacteria clinging to the knife-blade. +The surest time to do complete trimming is after the leaves fall in the +autumn, as diseased twigs are most easily recognized at that time, but +the orchard should be carefully watched in the spring also. If a large +limb shows the blight, it is perhaps best to cut the tree entirely down. +There is little hope for such a tree. + +A large pear-grower once said that no man with a sharp knife need fear +the fire-blight. Yet our country loses greatly by this disease each +year. + +[Illustration: FIG. 120. FIRE-BLIGHT BACTERIA +Magnified] + +It may be added that winter pruning tends to make the tree form much new +wood and thus favors the disease. Rich soil and fertilizers make it much +easier in a similar way for the tree to become a prey to blight. + + + =EXERCISE= + + Ask your teacher to show you a case of fire-blight on a pear or + apple tree. Can you distinguish between healthy and diseased wood? + Cut the twig open lengthwise and see how deep into the wood and how + far down the stem the disease extends. Can you tell surely from the + outside how far the twig is diseased? Can you find any twig that + does not show a distinct line of separation between diseased and + healthy wood? If so, the bacteria are still living in the cambium. + Cut out a small bit of the diseased portion and insert it under the + bark of a healthy, juicy twig within a few inches of its tip and + watch it from day to day. Does the tree catch the disease? This + experiment may prove to you how easily the disease spreads. If you + should see any drops like dew hanging from diseased twigs, touch a + little of this moisture to a healthy flower and watch for results. + + Cut and burn all diseased twigs that you can find. Estimate the + damage done by fire-blight. + + Farmers' bulletins on orchard enemies are published by the + Department of Agriculture, Washington, D.C., and can be had by + writing for them. They will help your father much in treating + fire-blight. + + +=Oat Smuts.= Let us go out into a near-by oat field and look for all the +blackened heads of grain that we can find. How many are there? To count +accurately let us select an area one foot square. We must look +carefully, for many of these blackened heads are so low that we shall +not see them at the first glance. You will be surprised to find as many +as thirty or forty heads in every hundred so blackened. These blackened +heads are due to a plant disease called _smut_. + +[Illustration: FIG. 121. LOOSE SMUT OF OATS +The glumes at _a_ more nearly destroyed than the glumes at _b_] + +When threshing-time comes you will notice a great quantity of black dust +coming from the grain as it passes through the machine. The air is full +of it. This black dust consists of the spores of a tiny fungous plant. +The fungous smut plant grows upon the oat plant, ripens its spores in +the head, and is ready to be thoroughly scattered among the grains of +the oats as they come from the threshing-machine. + +These spores cling to the grain and at the next planting are ready to +attack the sprouting plantlet. A curious thing about the smut is that it +can gain a foothold only on very young oat plants; that is, on plants +about an inch long or of the age shown in Fig. 121. + +When grain covered with smut spores is planted, the spores develop with +the sprouting seeds and are ready to attack the young plant as it breaks +through the seed-coat. You see, then, how important it is to have seed +grain free from smut. A substance has been found that will, without +injuring the seeds, kill all the smut spores clinging to the grain. This +substance is called _formalin_. Enough seed to plant a whole acre can be +treated with formalin at a cost of only a few cents. Such treatment +insures a full crop and clean seed for future planting. Try it if you +have any smut. + +[Illustration: FIG. 122. A CROP FROM OATS TREATED WITH FORMALIN] + +Fig. 122 illustrates what may be gained by using seeds treated to +prevent smut. The annual loss to the farmers of the United States from +smut on oats amounts to several millions of dollars. All that is needed +to prevent this loss is a little care in the treatment of seed and a +proper rotation of crops. + + + =EXERCISE= + + Count the smutted heads on a patch three feet square and estimate + the percentage of smut in all the wheat and oat fields near your + home. On which is it most abundant? Do you know of any fields that + have been treated for smut? If so, look for smut in these fields. + Ask how they were treated. Do you know of any one who uses + bluestone for wheat smut? Can oats be treated with bluestone? + + At planting time get an ounce of formalin at your drug store or + from the state experiment station. Mix this with three gallons of + water. This amount will treat three bushels of seeds. Spread the + seeds thinly on the barn floor and sprinkle them with the mixture, + being careful that all the seeds are thoroughly moistened. Cover + closely with blankets for a few hours and plant very soon after + treatment. Try this and estimate the per cent of smut at next + harvest-time. Write to your experiment station for a bulletin on + smut treatment. + +[Illustration: FIG. 123. A SCABBY SEED POTATO] + +[Illustration: FIG. 124. A HEALTHY SEED POTATO] + +=Potato Scab.= The scab of the white, or Irish, potato is one of the +commonest and at the same time most easily prevented of plant diseases. +Yet this disease diminishes the profits of the potato-grower very +materially. Fig. 123 shows a very scabby potato, while Fig. 124 +represents a healthy one. This scab is caused by a fungous growth on the +surface of the potato. Of course it lessens the selling-price of the +potatoes. If seed potatoes be treated to a bath of formalin just before +they are planted, the formalin will kill the fungi on the potatoes and +greatly diminish the amount of scab at the next harvest. Therefore +before they are planted, seed potatoes should be soaked in a weak +solution of formalin for about two hours. One-half pint of formalin to +fifteen gallons of water makes a proper solution. + +[Illustration: FIG. 125 +From a scabby potato, like the one in Fig. 123, this yield was obtained] + +[Illustration: FIG. 126 +From a healthy potato, like the one in Fig. 124, this yield was obtained] + +[Illustration: FIG. 127. EFFECT OF SPRAYING +Sprayed potatoes on left; unsprayed on right] + +One pint of formalin, or enough for thirty gallons of water, will cost +but thirty-five cents. Since this solution can be used repeatedly, it +will do for many bushels of seed potatoes. + +=Late Potato Blight.= The blight is another serious disease of the +potato. This is quite a different disease from the scab and so requires +different treatment. The blight is caused by another fungus, which +attacks the foliage of the potato plant. When the blight seriously +attacks a crop, it generally destroys the crop completely. In the year +1845 a potato famine extending over all the United States and Europe was +caused by this disease. + +[Illustration: FIG. 128. YIELD FROM TWO FIELDS OF THE SAME SIZE +The one at the top was sprayed; the one at the bottom was unsprayed] + +Spraying is the remedy for potato blight. Fig. 128 shows the effect of +spraying upon the yield. In this case the sprayed field yielded three +hundred and twenty-four bushels an acre, while the unsprayed yielded +only one hundred bushels to an acre. Fig. 127 shows the result of three +applications of the spraying mixture on the diseased field. Figs. 129 +and 130 show how the spraying is done. + +[Illustration: FIG. 129. SPRAYING MACHINE] + +[Illustration: FIG. 130. SPRAYING MACHINE] + + + =EXERCISE= + + Watch the potatoes at the next harvest and estimate the number that + is damaged by scab. You will remember that formalin is the + substance used to prevent grain smuts. Write to your state + experiment station for a bulletin telling how to use formalin, as + well as for information regarding other potato diseases. Give the + treatment a fair trial in a portion of your field this year and + watch carefully for results. Make an estimate of the cost of + treatment and of the profits. How does the scab injure the value of + the potato? The late blight can often be recognized by its odor. + Did you ever smell it as you passed an affected field? + +[Illustration: FIG. 131. CLUB ROOT] + +=Club Root.= Club root is a disease of the cabbage, turnip, cauliflower, +etc. Its general effect is shown in the illustration (Fig. 131). +Sometimes this disease does great damage. It can be prevented by using +from eighty to ninety bushels of lime to an acre. + +=Black Knot.= Black knot is a serious disease of the plum and of the +cherry tree. It attacks the branches of the tree; it is well +illustrated in Fig. 132. Since it is a contagious disease, great care +should be exercised to destroy all diseased branches of either wild or +cultivated plums or cherries. In many states its destruction is enforced +by law. All black knot should be cut out and burned some time before +February of each year. This will cost little and save much. + +[Illustration: FIG. 132. BLACK KNOT] + +=Peach Leaf Curl.= Peach leaf curl does damage amounting to about +$3,000,000 yearly in the United States. It can be almost entirely +prevented by spraying the tree with Bordeaux mixture or lime-sulphur +wash before the buds open in the spring. It is not safe to use strong +Bordeaux mixture on peach trees when they are in leaf. + +[Illustration: FIG. 133. MOLDY PEACHES] + +=Cotton Wilt.= Cotton wilt when it once establishes itself in the soil +completely destroys the crop. The fungus remains in the soil, and no +amount of spraying will kill it. The only known remedy is to cultivate a +resistant variety of cotton or to rotate the crop. + +[Illustration: FIG. 134. PEACH MUMMIES] + +=Fruit Mold.= Fruit mold, or brown rot, often attacks the unripe fruit +on the tree, and turns it soft and brown and finally fuzzy with a coat +of mildew. Fig. 133 shows some peaches thus attacked. Often the fruits +do not fall from the trees but shrivel up and become "mummies" (Fig. +134). This rot is one of the most serious diseases of plums and peaches. +It probably diminishes the value of the peach harvest from 50 to 75 per +cent. Spraying according to the directions in the Appendix will kill the +disease. + +[Illustration: FIG. 135. HALF OF TREE SPRAYED TO PREVENT PEACH CURL +Note the difference in foliage and fruit on the sprayed and unsprayed +halves of the tree, and the difference in yield shown below] + + + + +CHAPTER VII + +ORCHARD, GARDEN, AND FIELD INSECTS + + +SECTION XXXI. INSECTS IN GENERAL + +The farmer who has fought "bugs" on crop after crop needs no argument to +convince him that insects are serious enemies to agriculture. Yet even +he may be surprised to learn that the damage done by them, as estimated +by good authority, amounts to millions and millions of dollars yearly in +the United States and Canada. + +[Illustration: FIG. 136. ANTS] + +Every one thinks he knows what an insect is. If, however, we are willing +in this matter to make our notion agree with that of the people who have +studied insects most and know them best, we must include among the true +insects only such air-breathing animals as have six legs, no more, and +have the body divided into three parts--head, thorax, and abdomen. These +parts are clearly shown in Fig. 136, which represents the ant, a true +insect. All insects do not show the divisions of the body so clearly as +this figure shows them, but on careful examination you can usually make +them out. The head bears one pair of feelers, and these in many insects +serve also as organs of smell and sometimes of hearing. Less prominent +feelers are to be found in the region of the mouth. These serve as +organs of taste. + +[Illustration: FIG. 137. PARTS OF AN INSECT] + +[Illustration: FIG. 138. COMPOUND EYE OF DRAGON FLY] + +The eyes of insects are especially noticeable. Close examination shows +them to be made up of a thousand or more simple eyes. Such an eye is +called a _compound eye_. An enlarged view of one of these is shown in +Fig. 138. + +Attached to the thorax are the legs and also the wings, if the insect +has wings. The rear portion is the abdomen, and this, like the other +parts, is composed of parts known as segments. The insect breathes +through openings in the abdomen and thorax called _spiracles_ (see Fig. +137). + +An examination of spiders, mites, and ticks shows eight legs; therefore +these do not belong to the true insects, nor do the thousand-legged +worms and their relatives. + +[Illustration: FIG. 139. THE HOUSE FLY +_a_, egg; _b_, larva, or maggot; _c_, pupa; _d_, adult male. (All +enlarged)] + +The chief classes of insects are as follows: the flies, with two wings +only; the bees, wasps, and ants, with four delicate wings; the beetles, +with four wings--two hard, horny ones covering the two more delicate +ones. When the beetle is at rest its two hard wings meet in a straight +line down the back. This peculiarity distinguishes it from the true bug, +which has four wings. The two outer wings are partly horny, and in +folding lap over each other. Butterflies and moths are much alike in +appearance but differ in habit. The butterfly works by day and the moth +by night. Note the knob on the end of the butterfly's feeler (Fig. 143). +The moth has no such knob. + +It is important to know how insects take their food, for by knowing this +we are often able to destroy insect pests. Some are provided with mouth +parts for chewing their food; others have a long tube with which they +pierce plants or animals and, like the mosquito, suck their food from +the inside. Insects of this latter class cannot of course be harmed by +poison on the surface of the leaves on which they feed. + +[Illustration: FIG. 140. A TYPICAL BUG +_a_, adult; _b_, side view of sucking mouth-part Both _a_ and _b_ are +much enlarged] + +[Illustration: Fig. 141. BEETLE +_a_, larva; _b_, pupa; _c_, adult; _d_, burrow] + +Many insects change their form from youth to old age so much that you +can scarcely recognize them as the same creatures. First comes the egg. +The egg hatches into a worm-like animal known as a grub, maggot, or +caterpillar, or, as scientists call it, a _larva_. This creature feeds +and grows until finally it settles down and spins a home of silk, called +a _cocoon_ (Fig. 145). If we open the cocoon we shall find that the +animal is now covered with a hard outside skeleton, that it cannot move +freely, and that it cannot eat at all. The animal in this state is known +as the _pupa_ (Figs. 145 and 146). Sometimes, however, the pupa is not +covered by a cocoon, sometimes it is soft, and sometimes it has some +power of motion (Fig. 141). After a rest in the pupa stage the animal +comes out a mature insect (Figs. 142 and 143). + +From this you can see that it is especially important to know all you +can about the life of injurious insects, since it is often easier to +kill these pests at one stage of their life than at another. Often it is +better to aim at destroying the seemingly harmless beetle or butterfly +than to try to destroy the larvæ that hatch from its eggs, although, as +you must remember, it is generally the larvæ that do the most harm. +Larvæ grow very rapidly; therefore the food supply must be great to meet +the needs of the insect. + +[Illustration: FIG. 142. MOTH AND COCOON] + +Some insects, the grasshopper for example, do not completely change +their form. Fig. 147 represents some young grasshoppers, which very +closely resemble their parents. + +[Illustration: FIG. 143. BUTTERFLY] + +[Illustration: FIG. 144. STRUCTURE OF THE CATERPILLAR] + +[Illustration: FIG. 145. MOTH PUPA IN COCOON] + +Insects lay many eggs and reproduce with remarkable rapidity. Their +number therefore makes them a foe to be much dreaded. The queen honeybee +often lays as many as 4000 eggs in twenty-four hours. A single house fly +lays between 100 and 150 eggs in one day. The mosquito lays eggs in +quantities of from 200 to 400. The white ant often lays 80,000 in a day, +and so continues for two years, probably laying no less than 40,000,000 +eggs. In one summer the bluebottle fly could have 500,000,000 +descendants if they all lived. The plant louse, at the end of the fifth +brood, has laid in a single year enough eggs to produce 300,000,000 +young. Of course every one knows that, owing to enemies and diseases +(for the insects have enemies which prey on them just as they prey on +plants) comparatively few of the insects hatched from these eggs live +till they are grown. + +[Illustration: FIG. 146. A BUTTERFLY PUPA +Note outline of the butterfly] + +The number of insects which are hurtful to crops, gardens, flowers, and +forests seems to be increasing each season. Therefore farm boys and +girls should learn to recognize these harmful insects and to know how +they live and how they may be destroyed. Those who know the forms and +habits of these enemies of plants and trees are far better prepared to +fight them than are those who strike in the dark. Moreover such +knowledge is always a source of interest and pleasure. If you begin to +study insects, you will soon find your love for the study growing. + +[Illustration: FIG. 147. THE GROWTH OF A GRASSHOPPER] + + + =EXERCISE= + + Collect cocoons and pupæ of insects and hatch them in a + breeding-cage similar to the one illustrated in Fig. 149. Make + several cages of this kind. Collect larvæ of several kinds; supply + them with food from plants upon which you found them. Find out the + time it takes them to change into another stage. Write a + description of this process. + + The plant louse could produce in its twelfth brood + 10,000,000,000,000,000,000,000 offspring. Each louse is about one + tenth of an inch long. If all should live and be arranged in single + file, how many miles long would such a procession be? + +[Illustration: FIG. 148. PLANT LICE] + +[Illustration: FIG. 149. CAGE IN WHICH TO BREED INSECTS +Flower-pot, lamp-chimney, and cloth] + + +SECTION XXXII. ORCHARD INSECTS + +=The San Jose Scale.= The San Jose scale is one of the most dreaded +enemies of fruit trees. It is in fact an outlaw in many states. It is an +unlawful act to sell fruit trees affected by it. Fig. 150 shows a view +of a branch nearly covered with this pest. Although this scale is a very +minute animal, yet so rapidly does it multiply that it is very +dangerous to the tree. Never allow new trees to be brought into your +orchard until you feel certain that they are free from the San Jose +scale. If, however, it should in any way gain access to your orchard, +you can prevent its spreading by thorough spraying with what is known as +the lime-sulphur mixture. This mixture has long been used on the Pacific +coast as a remedy for various scale insects. When it was first tried in +other parts of the United States the results were not satisfactory and +its use was abandoned. However, later experiments with it have proved +that the mixture is thoroughly effective in killing this scale and that +it is perfectly harmless to the trees. Until the lime-sulphur mixture +proved to be successful the San Jose scale was a most dreaded nursery +and orchard foe. It was even thought necessary to destroy infected +trees. The lime-sulphur mixture and some other sulphur washes not only +kill the San Jose scale but are also useful in reducing fungous injury. + +[Illustration: FIG. 150 SAN JOSE SCALE] + +[Illustration: FIG. 151. SINGLE SAN JOSE SCALE +Magnified] + +There are several ways of making the lime-sulphur mixture. It is +generally best to buy a prepared mixture from some trustworthy dealer. +If you find the scale on your trees, write to your state experiment +station for directions for combating it. + +[Illustration: FIG. 152. THE CODLING MOTH +_a_, burrow of worm in apple; _b_, place where worm enters; _c_, place +where worm leaves; _e_, the larva; _d_, the pupa; _i_, the cocoon; _f_ +and _g_, moths; _h_, magnified head of larva] + +=The Codling Moth.= The codling moth attacks the apple and often causes +a loss of from twenty-five to seventy-five per cent of the crop. In the +state of New York this insect is causing an annual loss of about three +million dollars. The effect it has on the fruit is most clearly seen in +Fig. 152. The moth lays its egg upon the young leaves just after the +falling of the blossom. She flies on from apple to apple, depositing an +egg each time until from fifty to seventy-five eggs are deposited. The +larva, or "worm," soon hatches and eats its way into the apple. Many +affected apples ripen too soon and drop as "windfalls." Others remain on +the tree and become the common wormy apples so familiar to growers. The +larva that emerges from the windfalls moves generally to a tree, crawls +up the trunk, and spins its cocoon under a ridge in the bark. From the +cocoon the moth comes ready to start a new generation. The last +generation of the larvæ spends the winter in the cocoon. + +[Illustration: FIG. 153. SPRAYING THE ORCHARD BRINGS LUSCIOUS FRUIT +The picture in the corner at the top shows the right time to spray for +codling moth] + +_Treatment._ Destroy orchard trash which may serve as a winter home. +Scrape all loose bark from the tree. Spray the tree with arsenate of +lead as soon as the flowers fall. A former method of fighting this pest +was as follows: bands of burlap four inches wide tied around the tree +furnished a hiding-place for larvæ that came from windfalls or crawled +from wormy apples on the tree. The larvæ caught under the bands were +killed every five or six days. We know now, however, that a thorough +spraying just after the blossoms fall kills the worms and renders the +bands unnecessary. Furthermore, spraying prevents wormy apples, while +banding does not. Follow the first spraying by a second two weeks later. + +It is best to use lime-sulphur mixture or the Bordeaux mixture with +arsenate of lead for a spray. Thus one spraying serves against both +fungi and insects. + +[Illustration: FIG. 154. PLUM CURCULIO +Larva, pupa, adult, and mark on the fruit. (Enlarged)] + +=The Plum Curculio.= The plum curculio, sometimes called the plum +weevil, is a little creature about one fifth of an inch long. In spite +of its small size the curculio does, if neglected, great damage to our +fruit crop. It injures peaches, plums, and cherries by stinging the +fruit as soon as it is formed. The word "stinging" when applied to +insects--- and this case is no exception--means piercing the object +with the egg-layer (ovipositor) and depositing the egg. Some insects +occasionally use the ovipositor merely for defense. The curculio has an +especially interesting method of laying her egg. First she digs a hole, +in which she places the egg and pushes it well down. Then with her snout +she makes a crescent-shaped cut in the skin of the plum, around the egg. +This mark is shown in Fig. 154. As this peculiar cut is followed by a +flow of gum, you will always be able to recognize the work of the +curculio. Having finished with one plum, this industrious worker makes +her way to other plums until her eggs are all laid. The maggotlike larva +soon hatches, burrows through the fruit, and causes it to drop before +ripening. The larva then enters the ground to a depth of several inches. +There it becomes a pupa, and later, as a mature beetle, emerges and +winters in cracks and crevices. + +[Illustration: FIG. 155. LEAF GALLS OF PHYLLOXERA ON CLINTON GRAPE LEAF] + +_Treatment._ Burn orchard trash which may serve as winter quarters. +Spraying with arsenate of lead, using two pounds of the mixture to fifty +gallons of water, is the only successful treatment for the curculio. For +plums and peaches, spray first when the fruit is free from the calyx +caps, or dried flower-buds. Repeat the spraying two weeks later. For +late peaches spray a third time two weeks after the second spraying. +This poisonous spray will kill the beetles while they are feeding or +cutting holes in which to lay their eggs. + +[Illustration: FIG. 156. THE CANKERWORM] + +Fowls in the orchard do good by capturing the larvæ before they can +burrow, while hogs will destroy the fallen fruit before the larvæ can +escape. + +=The Grape Phylloxera.= The grape phylloxera is a serious pest. You have +no doubt seen its galls upon the grape leaf. These galls are caused by a +small louse, the phylloxera. Each gall contains a female, which soon +fills the gall with eggs. These hatch into more females, which emerge +and form new galls, and so the phylloxera spreads (see Fig. 155). + +_Treatment._ The Clinton grape is most liable to injury from this pest. +Hence it is better to grow other more resistant kinds. Sometimes the +lice attack the roots of the grape vines. In many sections where +irrigation is practiced the grape rows are flooded when the lice are +thickest. The water drowns the lice and does no harm to the vines. + +=The Cankerworm.= The cankerworm is the larva of a moth. Because of its +peculiar mode of crawling, by looping its body, it is often called the +looping worm or measuring worm (Fig. 157, _c_). These worms are such +greedy eaters that in a short time they can so cut the leaves of an +orchard as to give it a scorched appearance. Such an attack practically +destroys the crop and does lasting injury to the tree. The worms are +green or brown and are striped lengthwise. If the tree is jarred, the +worm has a peculiar habit of dropping toward the ground on a silken +thread of its own making (Fig. 156). + +[Illustration: FIG. 157. THE SPRING CANKERWORM +_a_, egg mass; _b_, egg, magnified; _c_, larva; _d_, female moth; _e_, +male moth] + +In early summer the larvæ burrow within the earth and pupate there; +later they emerge as adults (Fig. 157, _d_ and _e_). You observe the +peculiar difference between the wingless female, _d_, and the winged +male, _e_. It is the habit of this wingless female to crawl up the trunk +of some near-by tree in order to deposit her eggs upon the twigs. These +eggs (shown at _a_ and _b_) hatch into the greedy larvæ that do so much +damage to our orchards. + +Nearly all the common birds feed freely upon the cankerworm, and benefit +the orchard in so doing. The chickadee is perhaps the most useful. A +recent writer is very positive that each chickadee will devour on an +average thirty female cankerworm moths a day; and that if the average +number of eggs laid by each female is one hundred and eighty-five, one +chickadee would thus destroy in one day five thousand five hundred and +fifty eggs, and, in the twenty-five days in which the cankerworm moths +crawl up the tree, would rid the orchard of one hundred and thirty-eight +thousand seven hundred and fifty. These birds also eat immense numbers +of cankerworm eggs before they hatch into worms. + +[Illustration: FIG. 158. EGGS OF THE FALL CANKERWORM] + +_Treatment._ The inability of the female to fly gives us an easy way to +prevent the larval offspring from getting to the foliage of our trees, +for we know that the only highway open to her or her larvæ leads up the +trunk. We must obstruct this highway so that no crawling creature may +pass. This is readily done by smoothing the bark and fitting close to it +a band of paper, and making sure that it is tight enough to prevent +anything from crawling underneath. Then smear over the paper something +so sticky that any moth or larva that attempts to pass will be +entangled. Printer's ink will do very well, or you can buy either +dendrolene or tanglefoot. + +[Illustration: FIG. 159. APPLE-TREE TENT CATERPILLAR +_a_, eggs; _b_, cocoon; _c_, caterpillar] + +Encourage the chickadee and all other birds, except the English sparrow, +to stay in your orchard. This is easily done by feeding and protecting +them in their times of need. + +=The Apple-Tree Tent Caterpillar.= The apple-tree tent caterpillar is a +larva so well known that you only need to be told how to guard against +it. The mother of this caterpillar is a reddish moth. This insect passes +the winter in the egg state securely fastened on the twigs as shown in +Fig. 159, _a_. + +_Treatment._ There are three principal methods, (1) Destroy the eggs. +The egg masses are readily seen in winter and may easily be collected +and burned by boys. The chickadee eats great quantities of these eggs. +(2) With torches burn the nests at dusk when all the worms are within. +You must be very careful in burning or you will harm the young branches +with their tender bark. (3) Encourage the residence of birds. Urge your +neighbors to make war on the larvæ, too, since the pest spreads rapidly +from farm to farm. Regularly sprayed orchards are rarely troubled by +this pest. + +[Illustration: FIG. 160. THE TWIG GIRDLER AT ITS DESTRUCTIVE WORK +_a_, the girdler; _b_, the egg-hole; _c_, the groove cut by girdler; +_e_, the egg] + +=The Twig Girdler.= The twig girdler lays her eggs in the twigs of pear, +pecan, apple, and other trees. It is necessary that the larvæ develop in +dead wood. This the mother provides by girdling the twig so deeply that +it will die and fall to the ground. + +_Treatment._ Since the larvæ spend the winter in the dead twigs, burn +these twigs in autumn or early spring and thus destroy the pest. + +=The Peach-Tree Borer.= In Fig. 161 you see the effect of the peach-tree +borer's activity. These borers often girdle and thereby kill a tree. +Fig. 162 shows the adult state of the insect. The eggs are laid on peach +or plum trees near the ground. As soon as the larva emerges, it bores +into the bark and remains there for months, passing through the pupa +stage before it comes out to lay eggs for another generation. + +[Illustration: FIG. 161. BORER SIGNS AROUND BASE OF PEACH TREE] + +_Treatment._ If there are only a few trees in the orchard, digging the +worms out with a knife is the best way of destroying them. You can know +of the borer's presence by the exuding gum often seen on the tree-trunk. +If you pile earth around the roots early in the spring and remove it in +the late fall, the winter freezing and thawing will kill many of the +larvæ. + + + =EXERCISE= + + How many apples per hundred do you find injured by the codling + moth? Collect some cocoons from a pear or an apple tree in winter, + place in a breeding-cage, and watch for the moths that come out. Do + you ever see the woodpecker hunting for these same cocoons? Can you + find cocoons that have been emptied by this bird? Estimate how many + he considers a day's ration. How many apples does he thus save? + + [Illustration: FIG. 162. PEACH-TREE BORERS, MALE AND FEMALE + Female with broad yellow band across abdomen] + + Watch the curculio lay her eggs in the plums, peaches, or cherries. + What per cent of fruit is thus injured? Estimate the damage. Let + the school offer a prize for the greatest number of + tent-caterpillar eggs. Watch such trees as the apple, the wild and + the cultivated cherry, the oak, and many others. + + Make a collection of insects injurious to orchard fruits, showing + in each case the whole life history of the insect, that is, eggs, + larva, pupa, and the mature insects. + +[Illustration: THE TROUBLESOME CHINCH BUG (ENLARGED) +1, bugs on plant; 2, eggs; 3, young bug; 4 and 5, older bugs; 6, +long-winged bug; 7 and 8, short-winged bug] + + +SECTION XXXIII. GARDEN AND FIELD INSECTS + +=The Cabbage Worm.= The cabbage worm of the early spring garden is a +familiar object, but you may not know that the innocent-looking little +white butterflies hovering about the cabbage patch are laying eggs which +are soon to hatch and make the dreaded cabbage worms. In Fig. 164 _a_ +and _b_ show the common cabbage butterfly, _c_ shows several examples of +the caterpillar, and _d_ shows the pupa case. In the pupa stage the +insects pass the winter among the remains of old plants or in near-by +fences or in weeds or bushes. Cleaning up and burning all trash will +destroy many pupæ and thus prevent many cabbage worms. In Fig. 164 _e_ +and _f_ show the moth and zebra caterpillar; _g_ represents a moth which +is the parent of the small green worm shown at _h_. This worm is a +common foe of the cabbage plant. + +[Illustration: FIG. 163. THE DREADED CHINCH BUG] + +_Treatment._ Birds aid in the destruction of this pest. Paris green +mixed with air-slaked lime will also kill many larvæ. After the cabbage +has headed, it is very difficult to destroy the worm, but pyrethrum +insect powder used freely is helpful. + +=The Chinch Bug.= The chinch bug, attacking as it does such important +crops as wheat, corn, and grasses, is a well-known pest. It probably +causes more money loss than any other garden or field enemy. In Orange +county, North Carolina, farmers were once obliged to suspend +wheat-growing for two years on account of the chinch bug. In one year in +the state of Illinois this bug caused a loss of four million dollars. + +[Illustration: FIG. 164. CABBAGE WORMS AND BUTTERFLIES] + +_Treatment._ Unfortunately we cannot prevent all of the damage done by +chinch bugs, but we can diminish it somewhat by good clean agriculture. +Destroy the winter homes of the insect by burning dry grass, leaves, and +rubbish in fields and fence rows. Although the insect has wings, it +seldom or never uses them, usually traveling on foot; therefore a deep +furrow around the field to be protected will hinder or stop the progress +of an invasion. The bugs fall into the bottom of the furrow, and may +there be killed by dragging a log up and down the furrow. Write to the +Division of Entomology, Washington, for bulletins on the chinch bug. +Other methods of prevention are to be found in these bulletins. + +[Illustration: FIG. 165. A PLANT LOUSE COLONY] + +=The Plant Louse.= The plant louse is very small, but it multiplies with +very great rapidity. During the summer the young are born alive, and it +is only toward fall that eggs are laid. The individuals that hatch from +eggs are generally wingless females, and their young, born alive, are +both winged and wingless. The winged forms fly to other plants and start +new colonies. Plant lice mature in from eight to fourteen days. + +The plant louse gives off a sweetish fluid of which some ants are very +fond. You may often see the ants stroking these lice to induce them to +give off a freer flow of the "honey dew." This is really a method of +milking. However friendly and useful these "cows" may be to the ant, +they are enemies to man in destroying so many of his plants. + +_Treatment._ These are sucking insects. Poisons therefore do not avail. +They may be killed by spraying with kerosene emulsion or a strong soap +solution or with tobacco water. Lice on cabbages are easily killed by a +mixture of one pound of lye soap in four gallons of warm water. + +[Illustration: FIG. 166. A CHEAP SPRAYING OUTFIT] + +=The Squash Bug.= The squash bug does its greatest damage to young +plants. To such its attack is often fatal. On larger plants single +leaves may die. This insect is a serious enemy to a crop and is +particularly difficult to get rid of, since it belongs to the class of +sucking insects, not to the biting insects. For this reason poisons are +useless. + +[Illustration: FIG. 167. A SQUASH BUG] + +_Treatment._ About the only practicable remedy is to pick these insects +by hand. We can, however, protect our young plants by small nettings and +thus tide them over the most dangerous period of their lives. These bugs +greatly prefer the squash as food. You can therefore diminish their +attack on your melons, cucumbers, etc. by planting among the melons an +occasional squash plant as a "trap plant." Hand picking will be easier +on a few trap plants than over the whole field. A small board or large +leaf laid beside the young plant often furnishes night shelter for the +bugs. The bugs collected under the board may easily be killed every +morning. + +=The Flea-Beetle.= The flea-beetle inflicts much damage on the potato, +tomato, eggplant, and other garden plants. The accompanying figure shows +the common striped flea-beetle which lives on the tomato. The larva of +this beetle lives inside of the leaves, mining its way through the leaf +in a real tunnel. Any substance disagreeable to the beetle, such as +plaster, soot, ashes, or tobacco, will repel its attacks on the garden +crops. + +[Illustration: FIG. 168. FLEA-BEETLE AND LARVA +_a_, larva; _b_, adult. Lines on sides show real length of insects] + +=The Weevil.= The weevil is commonly found among seeds. Its attacks are +serious, but the insect may easily be destroyed. + +_Treatment._ Put the infected seeds in an air-tight box or bin, placing +on the top of the pile a dish containing carbon disulphide, a +tablespoonful to a bushel of seeds. The fumes of this substance are +heavy and will pass through the mass of seeds below and kill all the +weevils and other animals there. The bin should be closely covered with +canvas or heavy cloth to prevent the fumes from being carried away by +the air. Let the seeds remain thus from two to five days. Repeat the +treatment if any weevils are found alive. Fumigate when the temperature +is 70° Fahrenheit or above. In cold weather or in a loose bin the +treatment is not successful. _Caution:_ Do not approach the bin with a +light, since the fumes of the chemical used are highly inflammable. + +=The Hessian Fly.= The Hessian fly does more damage to the wheat crop +than all other insects combined, and probably ranks next to the chinch +bug as the second worst insect enemy of the farmer. It was probably +introduced into this country by the Hessian troops in the War of the +Revolution. + +[Illustration: FIG. 169. THE HESSIAN FLY] + +In autumn the insect lays its eggs in the leaves of the wheat. These +hatch into the larvæ, which move down into the crown of the plant, where +they pass the winter. There they cause on the plant a slight gall +formation, which injures or kills the plant. In the spring adult flies +emerge and lay eggs. The larvæ that hatch feed in the lower joints of +the growing wheat and prevent its proper growth. These larvæ pupate and +remain as pupæ in the wheat stubble during the summer. The fall brood of +flies appears shortly before the first heavy frost. + +_Treatment._ Burn all stubble and trash during July and August. If the +fly is very bad, it is well to leave the stubble unusually high to +insure a rapid spread of the fire. Burn refuse from the +threshing-machine, since this often harbors many larvæ or pupæ. Follow +the burning by deep plowing, because the burning cannot reach the +insects that are in the base of the plants. Delay the fall planting +until time for heavy frosts. + +=The Potato Beetle; Tobacco Worm.= The potato beetle, tobacco worm, +etc., are too well known to need description. Suffice it to say that no +good farmer will neglect to protect his crop from any pest that +threatens it. + +The increase, owing to various causes, of insects, of fungi, of +bacterial diseases, makes a study of these pests, of their origin, and +of their prevention a necessary part of a successful farmer's training. +Tillage alone will no longer render orchard, vineyard, and garden +fruitful. Protection from every form of plant enemies must be added to +tillage. + +[Illustration: FIG. 170. SPRAYING THE ORCHARD +One way of increasing the yield of fruit] + +In dealing with plants, as with human beings, the great object should be +not the cure but the prevention of disease. If disease can be prevented, +it is far too costly to wait for it to develop and then to attempt its +cure. Men of science are studying the new forms of diseases and new +insects as fast as they appear. These men are finding ways of fighting +old and new enemies. Young people who expect to farm should early learn +to follow their advice. + + + =EXERCISE= + + How does the squash bug resemble the plant louse? Is this a true + bug? Gather some eggs and watch the development of the insects in a + breeding-cage. Estimate the damage done to some crops by the + flea-beetle. What is the best method of prevention? + + [Illustration: FIG. 171. AN APPLE TREE SHOWING PROPER CARE] + + Do you know the large moth that is the mother of the tobacco worm? + You may often see her visiting the blossoms of the Jimson weed. + Some tobacco-growers cultivate a few of these weeds in a tobacco + field. In the blossom they place a little cobalt or "fly-stone" and + sirup. When the tobacco-worm moth visits this flower and sips the + poisoned nectar, she will of course lay no more troublesome eggs. + + +SECTION XXXIV. THE COTTON-BOLL WEEVIL + +So far as known, the cotton-boll weevil, an insect which is a native of +the tropics, crossed the Rio Grande River into Texas in 1891 and 1892. +It settled in the cotton fields around Brownsville. Since then it has +widened its destructive area until now it has invaded the whole +territory shown by the map on page 177. + +[Illustration: FIG. 172. ADULT COTTON-BOLL WEEVIL +Enlarged] + +This weevil is a small gray or reddish-brown snout-beetle hardly over a +quarter of an inch in length. In proportion to its length it has a long +beak. It belongs to a family of beetles which breed in pods, in seeds, +and in stalks of plants. It is a greedy eater, but feeds only on the +cotton plant. + +The grown weevils try to outlive the cold of winter by hiding snugly +away under grass clumps, cotton-stalks, rubbish, or under the bark of +trees. Sometimes they go down into holes in the ground. A comfortable +shelter is often found in the forests near the cotton fields, especially +in the moss on the trees. The weevils can stand a good deal of cold, but +fortunately many are killed by winter weather. Moreover birds destroy +many; hence by spring the last year's crop is very greatly diminished. + +In the spring, generally about the time cotton begins to form "squares," +the weevils shake off their long winter sleep and enter the cotton +fields with appetites as sharp as razors. Then shortly the females begin +to lay eggs. At first these eggs are laid only in the squares, and +generally only one to the square. The young grub hatches from these eggs +in two or three days. The newly hatched grub eats the inside of the +square, and the square soon falls to the ground. Entire fields may at +times be seen without a single square on the plants. Of course no fruit +can be formed without squares. + +[Illustration: FIG. 173. EGGS AMONG THE ANTHERS OF A SQUARE AT THE +POINT INDICATED BY THE ARROW] + +[Illustration: FIG. 174. CROSS SECTION SHOWING ANTHERS OF A SQUARE +WITH EGG OF WEEVIL, AND SHOWING THE HOLE WHERE THE EGG WAS DEPOSITED +Greatly enlarged] + +In from one to two weeks the grub or larva becomes fully grown and, +without changing its home, is transformed into the pupa state. Then in +about a week more the pupæ come out as adult weevils and attack the +bolls. They puncture them with their snouts and lay their eggs in the +bolls. The young grubs, this time hatching out in the boll, remain there +until grown, when they emerge through holes that they make. These holes +allow dampness to enter and destroy the bolls. This life-round continues +until cold weather drives the insects to their winter quarters. By that +time they have increased so rapidly that there is often one for every +boll in the field. + +[Illustration: FIG. 175. THE LARVA OF THE COTTON-BOLL WEEVIL +INJURING A SQUARE] + +This weevil is proving very hard to destroy. At present there seem but +few ways to fight it. One is to grow cotton that will mature too early +for the weevils to do it much harm. A second is to kill as many weevils +as possible by burning the homes that shelter them in winter. + +[Illustration: FIG. 176. PUPA OF COTTON-BOLL WEEVIL FROM ABOVE AND BELOW +Greatly enlarged] + +[Illustration: FIG. 177. THE PUPA OF THE COTTON-BOLL WEEVIL IN A SQUARE] + +The places best adapted for a winter home for the weevil are trash +piles, rubbish, driftwood, rotten wood, weeds, moss on trees, etc. A +further help, therefore, in destroying the weevil is to cut down and +burn all cotton-stalks as soon as the cotton is harvested. + +[Illustration: FIG. 178. A COTTON BOLL WITH FEEDING-HOLES OF WEEVIL, +AND BEARING THREE SPECIMENS OF THE INSECT] + +[Illustration: FIG. 179. THE MEXICAN COTTON-BOLL WEEVIL, +SHOWING STRUCTURE] + +This destroys countless numbers of larvæ and pupæ in the bolls and +greatly reduces the number of weevils. In addition, all cornstalks, all +trash, all large clumps of grass in neighboring fields, should be +burned, so as to destroy these winter homes of the weevil. Also avoid +planting cotton near trees. The bark, moss, and fallen leaves of the +tree furnish a winter shelter for the weevils. + +[Illustration: FIG. 180. A SERIES OF FULL GROWN WEEVILS, SHOWING +VARIATIONS IN SIZE] + +A third help in destroying the weevil is to rotate crops. If cotton does +not follow cotton, the weevil has nothing on which to feed the second +year. + +[Illustration: FIG. 181. MAP SHOWING DISTRIBUTION OF THE COTTON-BOLL +WEEVIL IN 1913] + +In adopting the first method mentioned the cotton growers have found +that by the careful selection of seed, by early planting, by a free use +of fertilizers containing phosphoric acid, and by frequent plowing, they +can mature a crop about thirty days earlier than they usually do. In +this way a good crop can be harvested before the weevils are ready to be +most destructive. + + + + +CHAPTER VIII + +FARM CROPS + + +Every crop of the farm has been changed and improved in many ways since +its forefathers were wild plants. Those plants that best serve the needs +of the farmer and of farm animals have undergone the most changes and +have received also the greatest care and attention in their production +and improvement. + +While we have many different kinds of farm crops, the cultivated soil of +the world is occupied by a very few. In our country the crop that is +most valuable and that occupies the greatest land area is generally +known as the _grass crop_. Included in the general term "grass crop" are +the grasses and clovers that are used for pasturage as well as for hay. +Next to grass in value come the great cereal, corn, and the most +important fiber crop, cotton, closely followed by the great bread crop, +wheat. Oats rank fifth in value, potatoes sixth, and tobacco seventh. +(These figures are for 1913.) + +Success in growing any crop is largely due to the suitableness of soil +and climate to that crop. When the planter selects both the most +suitable soil and the most suitable climate for each crop, he gets not +only the most bountiful yield from the crop but, in addition, he gets +the most desirable quality of product. A little careful observation and +study soon teach what kinds of soil produce crops of the highest +excellence. This learned, the planter is able to grow in each field the +several crops best adapted to that special type of soil. Thus we have +tobacco soils, trucking soils, wheat and corn soils. Dairying can be +most profitably followed in sections where crops like cowpeas, clover, +alfalfa, and corn are peculiarly at home. No one should try to grow a +new crop in his section until he has found out whether the crop which he +wants to grow is adapted to his soil and his climate. + +[Illustration: FIG. 182. ALFALFA IN THE STACK +This is the second cutting of the season] + +The figures below give the average amount of money made annually an acre +on our chief crops: + +Flowers and plants, $1911; nursery products, $261; onions, $140; sugar +cane, $55; small fruits, $110; hops, $175; vegetables, $78; tobacco, +$80; sweet potatoes, $55; hemp, $53; potatoes, $78; sugar beets, $54; +sorghum cane, $22; cotton, $22; orchard fruits, $110; peanuts, $21; +flax-seed, $14; cereals, $14; hay and forage, $11; castor beans, $6 +(United States Census Report). + + +SECTION XXXV. COTTON + +Although cotton was cultivated on the Eastern continent before America +was discovered, this crop owes its present kingly place in the business +world to the zeal and intelligence of its American growers. So great an +influence does it wield in modern industrial life that it is often +called King Cotton. Thousands upon thousands of people scan the +newspapers each day to see what price its staple is bringing. From its +bounty a vast army of toilers, who plant its seed, who pick its bolls, +who gin its staple, who spin and weave its lint, who grind its seed, who +refine its oil, draw daily bread. Does not its proper production deserve +the best thought that can be given it? + +In the cotton belt almost any well-drained soil will produce cotton. The +following kinds of soil are admirably suited to this plant: red and gray +loams with good clay subsoil; sandy soils over clay and sandstone and +limestone; rich, well-drained bottom-lands. The safest soils are medium +loams. Cotton land must always be well drained. + +Cotton was originally a tropical plant, but, strange to say, it seems to +thrive best in temperate zones. The cotton plant does best, according to +Newman, in climates which have (1) six months of freedom from frost; (2) +a moderate, well-distributed rainfall during the plant's growing period; +and (3) abundant sunshine and little rain during the plant's maturing +period. + +[Illustration: FIG. 183. GROWTH OF COTTON FROM DAY TO DAY + +In America the Southern states from Virginia to Texas have these +climatic qualities, and it is in these states that the cotton industry +has been developed until it is one of the giant industries of the world. +This development has been very rapid. As late as 1736 the cotton plant +was grown as an ornamental flowering plant in many front yards; in +1911, 16,250,276 bales of cotton were grown in the South. In recent +years the soil and climate of lower California and parts of Arizona and +New Mexico have been found well adapted to cotton. + +[Illustration: FIG. 184. COTTON IN THE GROWING SEASON] + +There are a great many varieties of cotton. Two types are mainly grown +by the practical American farmer. These are the short-stapled, upland +variety most commonly grown in all the Southern states, and the +beautiful, long-stapled, black-seeded sea-island type that grows upon +the islands and a portion of the mainland of Georgia, South Carolina, +and Florida. The air of the coast seems necessary for the production of +this latter variety. The seeds of the sea-island cotton are small, +smooth, and black. They are so smooth and stick so loosely to the lint +that they are separated from it by roller-gins instead of by saw-gins. +When these seeds are planted away from the soil and air of their ocean +home, the plant does not thrive. + +Many attempts have been made and are still being made to increase the +length of the staple of the upland types. The methods used are as +follows: selection of seed having a long fiber; special cultivation and +fertilization; crossing the short-stapled cotton on the long-stapled +cotton. This last process, as already explained, is called +_hybridizing_. Many of these attempts have succeeded, and there are now +a large number of varieties which excel the older varieties in +profitable yield. The new varieties are each year being more widely +grown. Every farmer should study the new types and select the one that +will best suit his land. The new types have been developed under the +best tillage. Therefore if a farmer would keep the new type as good as +it was when he began to grow it, he must give it the same good tillage, +and practice seed-selection. + +[Illustration: FIG. 185. COTTON READY FOR PICKING] + +The cotton plant is nourished by a tap-root that will seek food as +deeply as loose earth will permit the root to penetrate; hence, in +preparing land for this crop the first plowing should be done at least +with a two-horse plow and should be deep and thorough. This deep plowing +not only allows the tap-root to penetrate, but it also admits a +circulation of air. + +On some cotton farms it is the practice to break the land in winter or +early spring and then let it lie naked until planting-time. This is not +a good practice. The winter rains wash more plant food out of +unprotected soil than a single crop would use. It would be better, in +the late summer or fall, to plant crimson clover or some other +protective and enriching crop on land that is to be planted in cotton in +the spring. This crop, in addition to keeping the land from being +injuriously washed, would greatly help the coming cotton crop by leaving +the soil full of vegetable matter. + +In preparing for cotton-planting, first disk the land thoroughly, then +break with a heavy plow and harrow until a fine and mellow seed-bed is +formed. Do not spare the harrow at this time. It destroys many a weed +that, if allowed to grow, would have to be cut by costly hoeing. +Thorough work before planting saves much expensive work in the later +days of the crop. Moreover, no man can afford to allow his plant food +and moisture to go to nourish weeds, even for a short time. + +The rows should be from three to four feet apart. The width depends upon +the richness of the soil. On rich land the rows should be at least four +feet apart. This width allows the luxuriant plant to branch and fruit +well. On poorer lands the distance of the rows should not be so great. +The distribution of the seed in the row is of course most cheaply done +by the planter. As a rule it is best not to ridge the land for the seed. +Flat culture saves moisture and often prevents damage to the roots. In +some sections, however, where the land is flat and full of water, +ridging seems necessary if the land cannot be drained. + +[Illustration: FIG. 186. PICKING COTTON] + +The cheapest way of cultivating a crop is to prevent grass and weeds +from rooting, not to wait to destroy them after they are well rooted. To +do this, it is well to run the two-horse smoothing-harrow over the +land, across the rows, a few days after the young plants are up. Repeat +the harrowing in six or eight days. In addition to destroying the young +grass and weeds, this harrowing also removes many of the young cotton +plants and thereby saves much hoeing at "chopping-out" time. When the +plants are about two inches high they are "chopped out" to secure an +evenly distributed stand. It has been the custom to leave two stalks to +a hill, but many growers are now leaving only one. + +The number of times the crop has to be worked depends on the soil and +the season. If the soil is dry and porous, cultivate as often as +possible, especially after each rain. Never allow a crust to form after +a rain; the roots of plants must have air. Cultivation after each rain +forms a dry mulch on the top of the soil and thus prevents rapid +evaporation of moisture. + +If the fiber (the lint) only is removed from the land on which cotton is +grown, cotton is the least exhaustive of the great crops grown in the +United States. According to some recent experiments an average crop of +cotton removes in the lint only 2.75 pounds of nitrogen, phosphoric +acid, potash, lime, and magnesia per acre, while a crop of ten bushels +of wheat per acre removes 32.36 pounds of the same elements of plant +food. Inasmuch as this crop takes so little plant food from the soil, +the cotton-farmer has no excuse for allowing his land to decrease in +productiveness. Two things will keep his land in bounteous harvest +condition: first, let him return the seeds in some form to the land, or, +what is better, feed the ground seeds to cattle, make a profit from the +cattle, and return manure to the land in place of the seeds; second, at +the last working, let him sow some crop like crimson clover or rye in +the cotton rows to protect the soil during the winter and to leave humus +in the ground for the spring. + +The stable manure, if that is used, should be broadcasted over the +fields at the rate of six to ten tons an acre. If commercial fertilizers +are used, it may be best to make two applications. To give the young +plants a good start, apply a portion of the fertilizer in the drill just +before planting. Then when the first blooms appear, put the remainder of +the fertilizer in drills near the plants but not too close. Many good +cotton-growers, however, apply all the fertilizer at one time. + +[Illustration: FIG. 187. WEIGHING A DAY'S PICKING OF COTTON] + +_Relation of Stock to the Cotton Crop_. On many farms much of the money +for which the cotton is sold in the fall has to go to pay for the +commercial fertilizer used in growing the crop. Should not this fact +suggest efforts to raise just as good crops without having to buy so +much fertilizer? Is there any way by which this can be done? The +following suggestions may be helpful. Raise enough stock to use all the +cotton seed grown on the farm. To go with the food made from the cotton +seed, grow on the farm pea-vine hay, clover, alfalfa, and other such +nitrogen-gathering crops. This can be done at small cost. What will be +the result? + +First, to say nothing of the money made from the cattle, the large +quantity of stable manure saved will largely reduce the amount of +commercial fertilizer needed. The cotton-farmer cannot afford to neglect +cattle-raising. The cattle sections of the country are likely to make +the greatest progress in agriculture, because they have manure always on +hand. + +[Illustration: FIG. 188. MODERN COTTON BALES] + +Second, the nitrogen-gathering crops, while helping to feed the stock, +also reduce the fertilizer bills by supplying one of the costly elements +of the fertilizer. The ordinary cotton fertilizer consists principally +of nitrogen, of potash, and of phosphoric acid. Of these three, by far +the most costly is nitrogen. Now peas, beans, clover, and peanuts will +leave enough nitrogen in the soil for cotton, so that if they are +raised, it is necessary to buy only phosphoric acid and sometimes +potash. + + +SECTION XXXVI. TOBACCO + +The tobacco plant connects Indian agriculture with our own. It has +always been a source of great profit to our people. In the early +colonial days tobacco was almost the only money crop. Many rich men came +to America in those days merely to raise tobacco. + +Although tobacco will grow in almost any climate, the leaves, which, as +most of you know, are the salable part of the plant, get their desirable +or undesirable qualities very largely from the soil and from the climate +in which they grow. + +The soil in which tobacco thrives best is one which has the following +qualities: dryness, warmth, richness, depth, and sandiness. + +Commercial fertilizers also are almost a necessity; for, as tobacco land +is limited in area, the same land must be often planted in tobacco. +Hence even a fresh, rich soil that did not at first require fertilizing +soon becomes exhausted, and, after the land has been robbed of its plant +food by crop after crop of tobacco, frequent application of fertilizers +and other manures becomes necessary. However, even tobacco growers +should rotate their crops as much as possible. + +[Illustration: FIG. 189. A LEAF OF TOBACCO] + +Deep plowing--from nine to thirteen inches--is also a necessity in +preparing the land, for tobacco roots go deep into the soil. After this +deep plowing, harrow until the soil is thoroughly pulverized and is as +fine and mellow as that of the flower-garden. + +Unlike most other farm crops the tobacco plant must be started first in +a seed-bed. To prepare a tobacco bed the almost universal custom has +been to proceed as follows. Carefully select a protected spot. Over this +spot pile brushwood and then burn it. The soil will be left dry, and all +the weed seeds will be killed. The bed is then carefully raked and +smoothed and planted. Some farmers are now preparing their beds without +burning. A tablespoonful of seed will sow a patch twenty-five feet +square. A cheap cloth cover is put over the bed. If the seeds come up +well, a patch of this size ought to furnish transplants for five or six +acres. In sowing, it is not wise to cover the seed deeply. A light +raking in or an even rolling of the ground is all that is needed. + +[Illustration: FIG. 190. A PROMISING CROP OF TOBACCO] + +The time required for sprouting is from two to three weeks. The plants +ought to be ready for transplanting in from four to six weeks. Weeds +and grass should of course be kept out of the seed-bed. + +The plants, when ready, are transplanted in very much the same way as +cabbages and tomatoes. The transplanting was formerly done by hand, but +an effective machine is now widely used. The rows should be from three +to three and a half feet apart, and the plants in the rows about two or +three feet apart. If the plants are set so that the plow and cultivator +can be run with the rows and also across the rows, they can be more +economically worked. Tobacco, like corn, requires shallow cultivation. +Of course the plants should be worked often enough to give clean culture +and to provide a soil mulch for saving moisture. + +[Illustration: FIG. 191. TOPPING TOBACCO] + +In tobacco culture it is necessary to pinch off the "buttons" and to cut +off the tops of the main stalk, else much nourishment that should go to +the leaves will be given to the seeds. The suckers must also be cut off +for the same reason. + +The proper time for harvesting is not easily fixed; one becomes skillful +in this work only through experience in the field. Briefly, we may say +that tobacco is ready to be cut when the leaves on being held up to the +sun show a light or golden color, when they are sticky to the touch, and +when they break easily on being bent. Plants that are overripe are +inferior to those that are cut early. + +The operations included in cutting, housing, drying, shipping, sweating, +and packing require skill and practice. + + +SECTION XXXVII. WHEAT + +Wheat has been cultivated from earliest times. It was a chief crop in +Egypt and Palestine, and still holds its importance in the temperate +portions of Europe, Asia, Africa, Australia, and America. + +[Illustration: FIG. 192. A HAND] + +[Illustration: FIG. 193. WHEAT HEADS] + +This crop ranks third in value in the United States. It grows in cool, +in temperate, and in warm climates, and in many kinds of soil. It does +best in clay loam, and worst in sandy soils. Clogged and water-soaked +land will not grow wheat with profit to the farmer; for this reason, +where good wheat-production is desired the soil must be well drained +and in good physical condition--that is, the soil must be open, crumbly, +and mellow. + +Clay soils that are hard and lifeless can be made valuable for +wheat-production by covering the surface with manure, by good tillage, +and by a thorough system of crop-rotation. Cowpeas and other legumes +make a most valuable crop to precede wheat, for in growing they add +atmospheric nitrogen to the soil, and their roots loosen the root-bed, +thereby admitting a free circulation of air and adding humus to the +soil. Moreover, the legumes leave the soil with its grains fairly close +packed, and this is a help in wheat growing. + +One may secure a good seed-bed after cotton and corn as well as after +cowpeas and other legumes. They are summer-cultivated crops, and the +clean culture that has been given them renders the surface soil mellow +and the undersoil firm and compact. They are not so good, however, as +cowpeas, since they add no atmospheric nitrogen to the soil, as all +leguminous crops do. + +[Illustration: FIG. 194. ROOTS OF A SINGLE WHEAT PLANT] + +From one to two inches is the most satisfactory depth for planting +wheat. The largest number of seeds comes up when planted at this depth. +A mellow soil is very helpful to good coming up and provides a most +comfortable home for the roots of the plant. A compact soil below makes +a moist undersoil; and this is desirable, for the soil water is needed +to dissolve plant food and to carry it up through the plant, where it is +used in building tissue. + +There are a great many varieties of wheat: some are bearded, others are +smooth; some are winter and others are spring varieties. The +smooth-headed varieties are most agreeable to handle during harvest and +at threshing-time. Some of the bearded varieties, however, do so well in +some soils and climates that it is desirable to continue growing them, +though they are less agreeable to handle. No matter what variety you are +accustomed to raise, it may be improved by careful seed-selection. + +[Illustration: FIG. 195. SELECTING WHEAT SEED] + +The seed-drill is the best implement for planting wheat. It distributes +the grains evenly over the whole field and leaves the mellow soil in a +condition to catch what snow may fall and secure what protection it +affords. + +[Illustration: FIG. 196. ADJOINING WHEAT FIELDS +The yield of the lower field, forty-five bushels per acre, is due to +intelligent farming] + +In many parts of the country, because not enough live stock is raised, +there is often too little manure to apply to the wheat land. Where this +is the case commercial fertilizers must be used. Since soils differ +greatly, it is impossible to suggest a fertilizer adapted to all soils. +The elements usually lacking in wheat soils are nitrogen, phosphoric +acid, and potash. The land may be lacking in one of these plant foods or +in all; in either case a maximum crop cannot possibly be raised. The +section on manuring the soil will be helpful to the wheat-grower. + +[Illustration: FIG. 197. A BOUNTIFUL CROP OF WHEAT] + +It should be remembered always in buying fertilizers for wheat that +whenever wheat follows cowpeas or clover or other legumes there is +seldom need of using nitrogen in the fertilizer; the tubercles on the +pea or clover roots will furnish that. Hence, as a rule, only potash and +phosphoric acid will have to be purchased as plant food. + +The farmer is assisted always by a study of his crop and by a knowledge +of how it grows. If he find the straw inferior and short, it means that +the soil is deficient in nitrogen; but on the other hand, if the straw +be luxuriant and the heads small and poorly filled, he may be sure that +his soil contains too little phosphoric acid and potash. + + + =EXERCISE= + + Let the pupils secure several heads of wheat and thresh each + separately by hand. The grains should then be counted and their + plumpness and size observed. The practical importance of this is + obvious, for the larger the heads and the greater the number of + grains, the larger the yield per acre. Let them plant some of the + large and some of the small grains. A single test of this kind will + show the importance of careful seed-selection. + +[Illustration: FIG. 198 A WIDELY GROWN CROP] + + +SECTION XXXVIII. CORN + +When the white man came to this country he found the Indians using corn; +for this reason, in addition to its name _maize_, it is called _Indian +corn_. Before that time the civilized world did not know that there was +such a crop. The increase in the yield and the extension of the acres +planted in this strictly American crop have kept pace with the rapid +and wonderful growth of our country. Corn is king of the cereals and the +most important crop of American agriculture. It grows in almost every +section of America. There is hardly any limit to the uses to which its +grain and its stalks are now put. Animals of many kinds are fed on +rations into which it enters. Its grains in some form furnish food to +more people than does any other crop except possibly rice. Its stalk and +its cob are manufactured into many different and useful articles. + +A soil rich in either decaying animal or vegetable matter, loose, warm, +and moist but not wet, will produce a better crop of corn than any +other. Corn soil should always be well tilled and cultivated. + +The proper time to begin the cultivation of corn is before it is +planted. Plow well. A shallow, worn-out soil should not be used for +corn, but for cowpeas or rye. After thorough plowing, the harrow--either +the disk or spring-tooth--should be used to destroy all clods and leave +the surface mellow and fine. The best results will be obtained by +turning under a clover sod that has been manured from the savings of the +barnyard. + +When manure is not available, commercial fertilizers will often prove +profitable on poor lands. Careful trials will best determine how much +fertilizer to an acre is necessary, and what kinds are to be used. A +little study and experimenting on the farmer's part will soon enable him +to find out both the kind and the amount of fertilizer that is best +suited to his land. + +The seed for this crop should be selected according to the plan +suggested in Section XIX. + +[Illustration: FIG. 199. CORN SHOCKED FOR THE SHREDDER] + +The most economical method of planting is by means of the horse planter, +which, according to its adjustment, plants regularly in hills or in +drills. A few days after planting, the cornfield should be harrowed with +a fine-tooth harrow to loosen the top soil and to kill the grass and the +weed seeds that are germinating at the surface. When the corn plants +are from a half inch to an inch high, the harrow may again be used. A +little work before the weeds sprout will save many days of labor during +the rest of the season, and increase the yield. + +[Illustration: FIG. 200. THE DIFFERENCE IS DUE TO TILLAGE] + +Corn is a crop that needs constant cultivation, and during the growing +season the soil should be stirred at least four times. This cultivation +is for three reasons: + +1. To destroy weeds that would take plant food and water. + +2. To provide a mulch of dry soil so as to prevent the evaporation of +moisture. The action of this mulch has already been explained. + +3. Because "tillage is manure." Constant stirring of the soil allows the +air to circulate in it, provides a more effective mulch, and helps to +change unavailable plant food into the form that plants use. + +Deep culture of corn is not advisable. The roots in their early stages +of growth are shallow feeders and spread widely only a few inches below +the surface. The cultivation that destroys or disturbs the roots injures +the plants and lessens the yield. We cultivate because of the three +reasons given above, and not to stir the soil about the roots or to +loosen it there. + +[Illustration: FIG. 201.] + +In many parts of the country the cornstalks are left standing in the +fields or are burned. This is a great mistake, for the stalks are worth +a good deal for feeding horses, cattle, and sheep. These stalks may +always be saved by the use of the husker and shredder. Corn after being +matured and cut can be put in shocks and left thus until dry enough to +run through the husker and shredder. This machine separates the corn +from the stalk and husks it. At the same time it shreds tops, leaves, +and butts into a food that is both nutritious and palatable to stock. +For the amount that animals will eat, almost as much feeding value is +obtained from corn stover treated in this way as from timothy hay. The +practice of not using the stalks is wasteful and is fast being +abandoned. The only reason that so much good food is being left to decay +in the field is because so many people have not fully learned the +feeding value of the stover. + + + =EXERCISE= + + To show the effect of cultivation on the yield of corn, let the + pupils lay off five plats in some convenient field. Each plat need + consist of only two rows about twenty feet long. Treat each plat as + follows: + + Plat 1. No cultivation: let weeds grow. + + Plat 2. Mulch with straw. + + Plat 3. Shallow cultivation: not deeper than two inches and at + least five times during the growing season. + + Plat 4. Deep cultivation: at least four inches deep, so as to + injure and tear out some of the roots (this is a common method). + + Plat 5. Root-pruning: ten inches from the stalk and six inches + deep, prune the roots with a long knife. Cultivate five times + during the season. + + Observe plats during the summer, and at husking-time note results. + + +SECTION XXXIX. PEANUTS + +This plant is rich in names, being known locally as "ground pea," +"goober," "earthnut," and "pindar," as well as generally by the name of +"peanut." The peanut is a true legume, and, like other legumes, bears +nitrogen-gathering tubercles upon its roots. The fruit is not a real nut +but rather a kind of pea or bean, and develops from the blossom. After +the fall of the blossom the "spike," or flower-stalk, pushes its way +into the ground, where the nut develops. If unable to penetrate the soil +the nut dies. + +In the United States, North and South Carolina, Virginia, and Tennessee +have the most favorable climates for peanut culture. Suitable climate +and soil, however, may be found from New Jersey to the Mississippi +valley. A high, porous, sandy loam is the most suitable. Stiffer soils, +which may in some cases yield larger crops than the loams, are yet not +so profitable, for stiff soils injure the color of the nut. Lime is a +necessity and must be supplied if the soil is deficient. Phosphoric acid +and potash are needed. + +Greater care than is usually bestowed should be given to the selection +of the peanut seed. In addition to following the principles given in +Section XVIII, all musty, defective seeds must be avoided and all +frosted kernels must be rejected. Before it dries, the peanut seed is +easily injured by frost. The slightest frost on the vines, either before +or after the plants are dug, does much harm to the tender seed. + +[Illustration: FIG. 202. A PEANUT PLANT] + +In growing peanuts, thorough preparation of the soil is much better than +later cultivation. Destroy the crop of young weeds, but do not disturb +the peanut crop by late cultivation. Harvest before frost, and shock +high to keep the vines from the ground. + +The average yield of peanuts in the United States is twenty-two bushels +an acre. In Tennessee the yield is twenty-nine bushels an acre, and in +North Carolina and Virginia it reaches thirty bushels an acre. + + +SECTION XL. SWEET POTATOES + +The roots of sweet potatoes are put on the market in various forms. +Aside from the form in which they are ordinarily sold, some potatoes are +dried and then ground into flour, some are canned, some are used to make +starch, some furnish a kind of sugar called glucose, and some are even +used to make alcohol. + +The fact that there are over eighty varieties of potatoes shows the +popularity of the plant. Now it is evident that all of these varieties +cannot be equally desirable. Hence the wise grower will select his +varieties with prudent forethought. He should study his market, his +soil, and his seed (see Section XVIII). + +[Illustration: FIG. 203. SWEET POTATOES] + +Four months of mild weather, months free from frost and cold winds, are +necessary for the growing of sweet potatoes. In a mild climate almost +any loose, well-drained soil will produce them. A light, sandy loam, +however, gives a cleaner potato and one, therefore, that sells better. + +The sweet potato draws potash, nitrogen, and phosphoric acid from the +soil, but in applying these as fertilizers the grower must study and +know his own soil. If he does not he may waste both money and plant food +by the addition of elements already present in sufficient quantity in +the soil. The only way to come to reliable conclusions as to the needs +of the soil is to try two or three different kinds of fertilizers on +plats of the same soil, during the same season, and notice the resulting +crop of potatoes. + +Sweet potatoes will do well after almost any of the usual field crops. +This caution, however, should be borne in mind. Potatoes should not +follow a sod. This is because sods are often thick with cutworms, one of +the serious enemies of the potato. + +It is needless to say that the ground must be kept clean by thorough +cultivation until the vines take full possession of the field. + +In harvesting, extreme care should be used to avoid cutting and bruising +the potato, since bruises are as dangerous to a sweet potato as to an +apple, and render decay almost a certainty. Lay aside all bruised +potatoes for immediate use. + +For shipment the potatoes should be graded and packed with care. An +extra outlay of fifty cents a barrel often brings a return of a dollar a +barrel in the market. One fact often neglected by Southern growers who +raise potatoes for a Northern market is that the Northern markets demand +a potato that will cook dry and mealy, and that they will not accept the +juicy, sugary potato so popular in the South. + +The storage of sweet potatoes presents difficulties owing to their great +tendency to decay under the influence of the ever-present fungi and +bacteria. This tendency can be met by preventing bruises and by keeping +the bin free from rotting potatoes. The potatoes should be cleaned, and +after the moisture has been dried off they should be stored in a dry, +warm place. + +The sweet-potato vine makes a fair quality of hay and with proper +precaution may be used for ensilage. Small, defective, unsalable +potatoes are rich in sugar and starch and are therefore good stock food. +Since they contain so much water they must be used only as an aid to +other diet. + + +SECTION XLI. WHITE, OR IRISH, POTATOES + +Maize, or Indian corn, and potatoes are the two greatest gifts in the +way of food that America has bestowed on the other nations. Since their +adoption in the sixteenth century as a new food from recently discovered +America, white potatoes have become one of the world's most important +crops. + +[Illustration: FIG. 204. CULTIVATING AND RIDGING POTATOES] + +No grower will harvest large crops of potatoes unless he chooses soil +that suits the plant, selects his seed carefully, cultivates thoroughly, +feeds his land sufficiently, and sprays regularly. + +The soil should be free from potato scab. This disease remains in land +for several years. Hence if land is known to have any form of scab in +it, do not plant potatoes in such land. Select for this crop a deep and +moderately light, sandy loam which has an open subsoil and which is rich +in humus. The soil must be light enough for the potatoes, or tubers, to +enlarge easily and dry enough to prevent rot or blight or other +diseases. Potato soil should be so close-grained that it will hold +moisture during a dry spell and yet so well-drained that the tubers will +not be hurt by too much moisture in wet weather. + +If the land selected for potatoes is lacking in humus, fine compost or +well-rotted manure will greatly increase the yield. However, it should +be remembered that green manure makes a good home for the growth of scab +germs. Hence it is safest to apply this sort of manure in the fall, or, +better still, use a heavy dressing of manure on the crop which the +potatoes are to follow. Leguminous crops supply both humus and nitrogen +and, at the same time, improve the subsoil. Therefore such crops are +excellent to go immediately before potatoes. If land is well supplied +with humus, commercial fertilizers are perhaps safer than manure, for +when these fertilizers are used the amount of plant food is more easily +regulated. Select a fertilizer that is rich in potash. For gardens +unleached wood ashes make a valuable fertilizer because they supply +potash. Early potatoes need more fertilization than do late ones. While +potatoes do best on rich land, they should not be overfed, for a too +heavy growth of foliage is likely to cause blight. + +Be careful to select seed from sound potatoes which are entirely free +from scab. Get the kinds that thrive best in the section in which they +are to be planted and which suit best the markets in which they are to +be sold. Seed potatoes should be kept in a cool place so that they will +not sprout before planting-time. As a rule consumers prefer a smooth, +regularly shaped, shallow-eyed white or flesh-colored potato which is +mealy when cooked. Therefore, select seed tubers with these qualities. +It seems proved that when whole potatoes are used for seed the yield is +larger than when sliced potatoes are planted. It is of course too +costly to plant whole potatoes, but it is a good practice to cause the +plants to thrive by planting large seed pieces. + +[Illustration: FIG. 205. GATHERING POTATOES] + +Like other crops, potatoes need a thoroughly prepared seed-bed and +intelligent cultivation. Break the land deep. Then go over it with an +ordinary harrow until all clods are broken and the soil is fine and well +closed. The rows should be at least three feet from one another and the +seeds placed from twelve to eighteen inches apart in the row, and +covered to a depth of three or four inches. A late crop should be +planted deeper than an early one. Before the plants come up it is well +to go over the field once or twice with a harrow so as to kill all +weeds. Do not fail to save moisture by frequent cultivation. After the +plants start to grow, all cultivation should be shallow, for the roots +feed near the surface and should not be broken. Cultivate as often as +needed to keep down weeds and grass and to keep the ground fine. + +Allow potatoes to dry thoroughly before they are stored, but never allow +them to remain long in the sunshine. Never dig them in damp weather, for +the moisture clinging to them will cause them to rot. After the tubers +are dry, store them in barrels or bins in a dry, cool, and dark place. +Never allow them to freeze. + +Among the common diseases and insect pests that attack the leaves and +stems of potato vines are early blight, late blight, brown rot, the +flea-beetle, and the potato beetle, or potato bug. Spraying with +Bordeaux mixture to which a small portion of Paris green has been added +will control both the diseases and the pests. The spraying should begin +when the plants are five or six inches high and should not cease until +the foliage begins to die. + +Scab is a disease of the tubers. It may be prevented (1) by using seed +potatoes that are free from scab; (2) by planting land in which there is +no scab; and (3) by soaking the seed in formalin (see page 135). + + +SECTION XLII. OATS + +The oat plant belongs to the grass family. It is a hardy plant and, +under good conditions, a vigorous grower. It stands cold and wet better +than any other cereal except possibly rye. Oats like a cool, moist +climate. In warm climates, oats do best when they are sowed in the fall. +In cooler sections, spring seeding is more generally practiced. + +There are a great many varieties of oats. No one variety is best adapted +to all sections, but many varieties make fine crops in many sections. +Any variety is desirable which has these qualities: power to resist +disease and insect enemies, heavy grains, thin hulls, good color, and +suitability to local surroundings. + +As oats and rye make a better yield on poor land than any other cereals, +some farmers usually plant these crops on their poorest lands. However, +no land is too good to be used for so valuable a crop as oats. Oats +require a great deal of moisture; hence light, sandy soils are not so +well adapted to this crop as are the sandy loams and fine clay loams +with their closer and heavier texture. + +If oats are to be planted in the spring, the ground should be broken in +the fall, winter, or early spring so that no delay may occur at +seeding-time. But to have a thoroughly settled, compact seed-bed the +breaking of the land should be done at least a month before the seeding, +and it will help greatly to run over the land with a disk harrow +immediately after the breaking. + +[Illustration: FIG. 206. OATS +Common oats at left; side oats at right] + +Oats may be planted by scattering them broadcast or by means of a drill. +The drill is better, because the grains are more uniformly distributed +and the depth of planting is better regulated. The seeds should be +covered from one and a half to two inches deep. In a very dry season +three inches may not be too deep. The amount of seed needed to the acre +varies considerably, but generally the seeding is from two to three +bushels an acre. On poor lands two bushels will be a fair average +seeding; on good lands as much as three bushels should be used. + +[Illustration: FIG. 207. HARVESTING OATS] + +This crop fits in well, over wide areas, with various rotations. As the +purpose of all rotation is to keep the soil productive, oats should +alternate every few years with one of the nitrogen-gathering crops. In +the South, cowpeas, soy beans, clovers, and vetches may be used in this +rotation. In the North and West the clovers mixed with timothy hay make +a useful combination for this purpose. + +Spring-sowed oats, since they have a short growing season, need their +nitrogenous plant food in a form which can be quickly used. To supply +this nitrogen a top-dressing of nitrate of soda or sulphate of lime is +helpful. The plant can gather its food quickly from either of these +two. As fall-sowed oats have of course a longer growing season, the +nitrogen can be supplied by well-rotted manure, blood, tankage, or +fish-scrap. Use barnyard manure carefully. Do not apply too much just +before seeding, and use only thoroughly rotted manure. It is always +desirable to have a bountiful supply of humus in land on which oats are +to be planted. + +The time of harvesting will vary with the use which is to be made of the +oats. If the crop is to be threshed, the harvesting should be done when +the kernels have passed out of the milk into the hard dough state. The +lower leaves of the stalks will at this time have turned yellow, and the +kernels will be plump and full. Do not, however, wait too long, for if +you do the grain will shatter and the straw lose in feeding value. + +On the other hand, if the oats are to be cut for hay it is best to cut +them while the grains are still in the milk stage. At this stage the +leaves are still green and the plants are rich in protein. + +Oats should be cured quickly. It is very important that threshed oats +should be dry before they are stored. Should they on being stored still +contain moisture, they will be likely to heat and to discolor. Any +discoloring will reduce their value. Nor should oats ever be allowed to +remain long in the fields, no matter how well they may seem to be +shocked. The dew and the rain will injure their value by discoloring +them more or less. + +Oats are muscle-builders rather than fat-formers. Hence they are a +valuable ration for work animals, dairy cows, and breeding-stock. + + +SECTION XLIII. RYE + +Rye has the power of gathering its food from a wider area than most +other plants. Of course, then, it is a fine crop for poor land, and +farmers often plant it only on worn land. However, it is too good a +cereal to be treated in so ungenerous a fashion. As a cover-crop for +poor land it adds much humus to the soil and makes capital grazing. + +[Illustration: FIG. 208. RYE READY FOR CUTTING] + +There are two types of rye--the winter and the spring. The winter type +is chiefly grown in this country. Rye seeds should be bought as near +home as possible, for this plant thrives best when the new crop grows +under the same conditions as the seed crop. + +Rye will grow on almost any soil that is drained. Soils that are too +sandy for wheat will generally yield good crops of rye. Clay soils, +however, are not adapted to the plant nor to the grazing for which the +plant is generally sowed. For winter rye the land should be broken from +four to six inches. Harrows should follow the plows until the land is +well pulverized. In some cold prairie lands, however, rye is put in with +a grain-drill before a plow removes the stubble from the land. The +purpose of planting in this way is to let the stubble protect the young +plants from cold, driving winds. + +Rye should go into the ground earlier than wheat. In cold, bleak +climates, as well as on poor land, the seeding should be early. The +young plant needs to get rooted and topped before cold weather sets in. +The only danger in very early planting is that leaf-rust sometimes +attacks the forward crop. Of course the earlier the rye is ready for +fall and winter pasturage, the better. If a drill is used for planting, +a seeding of from three to four pecks to the acre should give a good +stand. In case the seeds are to be sowed broadcast, a bushel or a bushel +and a half for every acre is needed. The seed should be covered as wheat +seed is and the ground rolled. + +Rye is generally used as a grazing or as a soiling crop. Therefore its +value will depend largely on its vigorous growth in stems and leaves. To +get this growth, liberal amounts of nitrogenous fertilizer will have to +be applied unless the land is very rich. Put barnyard manure on the land +just after the first breaking and disk the manure into the soil. Acid +phosphate and kainite added to the manure may pay handsomely. A spring +top-dressing of nitrate of soda is usually helpful. + +Rye has a stiff straw and does not fall, or "lodge," so badly as some of +the other cereals. As soon as rye that is meant for threshing is cut, it +should be put up in shocks until it is thoroughly dry. Begin the cutting +when the kernels are in a tough dough state. The grain should never +stand long in the shocks. + + +SECTION XLIV. BARLEY + +Barley is one of the oldest crops known to man. The old historian Pliny +says that barley was the first food of mankind. Modern man however +prefers wheat and corn and potatoes to barley, and as a food this +ancient crop is in America turned over to the lower animals. Brewers use +barley extensively in making malt liquors. Barley grows in nearly all +sections of our country, but a few states--namely, Minnesota, +California, Wisconsin, Iowa, and North and South Dakota--are seeding +large areas to this crop. + +For malting purposes the barley raised on rather light, friable, porous +soil is best. Soils of this kind are likely to produce a medium yield of +bright grain. Fertile loamy and clay soils make generally a heavier +yield of barley, but the grain is dark and fit only to be fed to stock. +Barley is a shallow feeder, and can reach only such plant food as is +found in the top soil, so its food should always be put within reach by +a thorough breaking, harrowing, and mellowing of the soil, and by +fertilizing if the soil is poor. Barley has been successfully raised +both by irrigation and by dry-farming methods. It requires a +better-prepared soil than the other grain crops; it makes fine yields +when it follows some crop that has received a heavy dressing of manure. +Capital yields are produced after alfalfa or after root crops. This crop +usually matures within a hundred days from its seeding. + +[Illustration: FIG. 209. BARLEY] + +When the crop is to be sold to the brewers, a grain rich in starch +should be secured. Barley intended for malting should be fertilized to +this end. Many experiments have shown that a fertilizer which contains +much potash will produce starchy barley. If the barley be intended for +stock, you should breed so as to get protein in the grain and in the +stalk. Hence barley which is to be fed should be fertilized with +mixtures containing nitrogen and phosphoric acid. Young barley plants +are more likely to be hurt by cold than either wheat or oats. Hence +barley ought not to be seeded until all danger from frost is over. The +seeds should be covered deeper than the seeds of wheat or of oats. Four +inches is perhaps an average depth for covering. But the covering will +vary with the time of planting, with the kind of ground, with the +climate, and with the nature of the season. Fewer seeds will be needed +if the barley is planted by means of a drill. + +Like other cereals, barley should not be grown continuously on the same +land. It should take its place in a well-planned rotation. It may +profitably follow potatoes or other hoed crops, but it should not come +first after wheat, oats, or rye. + +Barley should be harvested as soon as most of its kernels have reached +the hard dough state. It is more likely to shatter its grain than are +other cereals, and it should therefore be handled with care. It must +also be watched to prevent its sprouting in the shocks. Be sure to put +few bundles in the shock and to cap the shock securely enough to keep +out dew and rain. If possible the barley should be threshed directly +from the shock, as much handling will occasion a serious loss from +shattering. + + +SECTION XLV. SUGAR PLANTS + +In the United States there are three sources from which sugar is +obtained; namely, the sugar-maple, the sugar-beet, and the sugar-cane. +In the early days of our country considerable quantities of maple sirup +and maple sugar were made. This was the first source of sugar. Then +sugar-cane began to be grown. Later the sugar-beet was introduced. + +=Maple Products.= In many states sirup and sugar are still made from +maple sap. In the spring when the sap is flowing freely maple trees are +tapped and spouts are inserted. Through these spouts the sap flows into +vessels set to catch it. The sap is boiled in evaporating-pans, and made +into either sirup or sugar. Four gallons of sap yield about one pound of +sugar. A single tree yields from two to six pounds of sugar in a season. +The sap cannot be kept long after it is collected. Practice and skill +are needed to produce an attractive and palatable grade of sirup or of +sugar. + +=Sugar-Beets.= The sugar-beet is a comparatively new root crop in +America. The amount of sugar that can be obtained from beets varies from +twelve to twenty per cent. The richness in sugar depends somewhat on the +variety grown and on the soil and the climate. + +So far most of our sugar-beet seeds have been brought over from Europe. +Some of our planters are now, however, gaining the skill and the +knowledge needed to grow these seeds. It is of course important to grow +seeds that will produce beets containing much sugar. + +[Illustration: FIG. 210. CATCHING MAPLE SAP] + +These beets do well in a great variety of soils if the land is rich, +well prepared, and well drained, and has a porous subsoil. + +Beets cannot grow to a large size in hard land. Hence deep plowing is +very necessary for this crop. The soil should be loose enough for the +whole body of the beet to remain underground. Some growers prefer spring +plowing and some fall plowing, but all agree that the land should not be +turned less than eight or ten inches. The subsoil, however, should not +be turned up too much at the first deep plowing. + +Too much care cannot be taken to make the seed-bed firm and mellow and +to have it free from clods. If the soil is dry at planting-time and +there is likelihood of high winds, the seed-bed may be rolled with +profit. Experienced growers use from ten to twelve pounds of seeds to an +acre. It is better to use too many rather than too few seeds, for it is +easy to thin out the plants, but rather difficult to transplant them. +The seeds are usually drilled in rows about twenty inches apart. Of +course, if the soil is rather warm and moist at planting-time, fewer +seeds will be needed than when germination is likely to be slow. + +[Illustration: FIG. 211. SUGAR-BEET] + +A good rotation should always be planned for this beet. A very +successful one is as follows: for the first year, corn heavily +fertilized with stable manure; for the second year, sugar-beets; for the +third year, oats or barley; for the fourth year, clover; then go back +again to corn. In addition to keeping the soil fertile, there are two +gains from this rotation: first, the clean cultivation of the corn crop +just ahead of the beets destroys many of the weed seeds; second, the +beets must be protected from too much nitrogen in the soil, for an +excess of nitrogen makes a beet too large to be rich in sugar. The +manure, heavily applied to the corn, will leave enough nitrogen and +other plant food in the soil to make a good crop of beets and avoid any +danger of an excess. + +When the outside leaves of the beet take on a yellow tinge and drop to +the ground, the beets are ripe. The mature beets are richer in sugar +than the immature, therefore they should not be harvested too soon. They +may remain in the ground without injury for some time after they are +ripe. Cold weather does not injure the roots unless it is accompanied by +freezing and thawing. + +[Illustration: FIG. 212. SUGAR-BEETS ON THE WAY TO A FACTORY] + +The beets are harvested by sugar-beet pullers or by hand. If the roots +are to be gathered by hand they are usually loosened by plowing on each +side of them. If the roots are stored they should be put in long, narrow +piles and covered with straw and earth to protect them from frost. A +ventilator placed at the top of the pile will enable the heat and +moisture to escape. If the beets get too warm they will ferment and some +of their sugar will be lost. + + +=Sugar-Cane.= Sugar-cane is grown along the Gulf of Mexico and the South +Atlantic coast. In Mississippi, in Alabama, Florida, Georgia, South +Carolina, northern Louisiana, and in northern Texas it is generally made +into sirup. In southern Louisiana and southern Texas the cane is usually +crushed for sugar or for molasses. + +[Illustration: FIG. 213. STALK OF SUGAR-CANE +_A-B_, joints of cane showing roots; _B-C_, stem; _C-D_, leaves] + +The sugar-cane is a huge grass. The stalk, which is round, is from one +to two inches in thickness. + +The stalks vary in color. Some are white, some yellow, some green, some +red, some purple, and some black, while others are a mixture of two or +three of these colors. As shown in Fig. 214 the stalk has joints at +distances of from two to six inches. These joints are called nodes, and +the sections between the nodes are known as internodes. The internodes +ripen from the roots upward, and as each ripens it casts its leaves. The +stalk, when ready for harvesting, has only a few leaves on the top. + +[Illustration: Fig. 214. STICK OF SUGAR-CANE +_A_, buds, or eyes; _C_, nodes; _D_, internodes; _X_, semi-transparent +dots in rows] + +Under each leaf and on alternate sides of the cane a bud, or "eye," +forms. From this eye the cane is usually propagated; for, while in +tropical countries the cane forms seeds, yet these seeds are rarely +fertile. When the cane is ripe it is stripped of leaves, topped, and cut +at the ground with a knife. The sugar is contained in solution in the +pith of the cane. + +Cane requires an enormous amount of water for its best growth, and where +the rainfall is not great enough, the plants are irrigated. It requires +from seventy-five to one hundred gallons of water to make a pound of +sugar. Cane does best where there is a rainfall of two inches a week. At +the same time a well-drained soil is necessary to make vigorous canes. + +The soils suited to this plant are those which contain large amounts of +fertilizing material and which can hold much water. In southern +Louisiana alluvial loams and loamy clay soils are cultivated. In +Georgia, Alabama, and Florida light, sandy soils, when properly +fertilized and worked, make good crops. + +[Illustration: FIG. 215. PLANTING SUGAR-CANE] + +[Illustration: FIG. 216. LOADING SUGAR-CANE] + +Cane is usually planted in rows from five to six feet apart. A trench is +opened in the center of the row with a plow and in this open furrow is +placed a continuous line of stalks which are carefully covered with +plow, cultivator, or hoe. From one to three continuous lines of stalks +are placed in the furrow. From two to six tons of seed cane are needed +for an acre. In favorable weather the cane soon sprouts and cultivation +begins. Cane should be cultivated at short intervals until the plants +are large enough to shade the soil. In Louisiana one planting of cane +usually gives two crops. The first is called plant cane; the second is +known as first-year stubble, or ratoon. Sometimes second-year stubble is +grown. + +[Illustration: FIG. 217. A COMMON TYPE OF SIRUP FACTORY] + +In Louisiana large quantities of tankage, cotton-seed meal, and acid +phosphate are used to fertilize cane-fields. Each country has its own +time for planting and harvesting. In Louisiana, for example, canes are +planted from October to April. In the United States cane is harvested +each year because of frost, but in tropical countries the stalks are +permitted to grow from fifteen to twenty-four months. + +On many farms a small mill, the rollers of which are turned by horses, +is used for crushing the juice out of the cane. The juice is then +evaporated in a kettle or pan. This equipment is very cheap and can +easily be operated by a small family. While these mills rarely extract +more than one half of the juice in the cane, the sirup made by them is +very palatable and usually commands a good price. Costly machinery which +saves most of the juice is used in the large commercial sugar houses. + + +SECTION XLVI. HEMP AND FLAX + +In the early ages of the world, mankind is supposed to have worn very +little or no clothing. Then leaves and the inner bark of trees were +fashioned into a protection from the weather. These flimsy garments were +later replaced by skins and furs. As man advanced in knowledge, he +learned how to twist wool and hairs into threads and to weave these into +durable garments. Still later, perhaps, he discovered that some plants +conceal under their outer bark soft, tough fibers that can be changed +into excellent cloth. Flax and hemp were doubtless among the first +plants to furnish this fiber. + +=Flax.= Among the fiber crops of the world, flax ranks next to cotton. +It is the material from which is woven the linen for sheets, towels, +tablecloths, shirts, collars, dresses, and a host of other articles. +Fortunately for man, flax will thrive in many countries and in many +climates. The fiber from which these useful articles are made, unlike +cotton fiber, does not come from the fruit, but from the stem. It is the +soft, silky lining of the bark which lies between the woody outside and +the pith cells of the stem. + +The Old World engages largely in flax culture and flax manufacture, but +in our country flax is grown principally for its seed. From the seeds we +make linseed oil, linseed-oil cake, and linseed meal. + +Flax grows best on deep, loamy soils, but also makes a profitable growth +on clay soils. With sufficient fertilizing material it can be grown on +sandy lands. Nitrogen is especially needed by this plant and should be +liberally supplied. To meet this demand for nitrogen, it pays to plant a +leguminous crop immediately before flax. + +[Illustration: FIG. 218. FLAX] + +After a mellow seed-bed has been made ready and after the weather is +fairly warm, sow, if a seed crop is desired, at the rate of from two to +three pecks an acre. A good seed crop will not be harvested if the +plants are too thick. On the other hand, if a fiber crop is to be +raised, it is desirable to plant more thickly, so that the stalks may +not branch, but run up into a single stem. From a bushel to two bushels +of seed is in this case used to an acre. Flax requires care and work +from start to finish. + +When the seeds are full and plump the flax is ready for harvesting. In +America a binder is generally used for cutting the stalks. Our average +yield of flax is from eight to fifteen bushels an acre. + +=Hemp.= Like flax, hemp adapts itself wonderfully to many countries and +many climates. However, in America most of our hemp is grown in +Kentucky. + +[Illustration: FIG. 219. CUTTING HEMP] + +Hemp needs soil rich enough to give the young plants a very rapid growth +in their early days so that they may form long fibers. To give this crop +abundant nitrogen without great cost, it should be grown in a rotation +which includes one of the legumes. Rich, well-drained bottom-lands +produce the largest yields of hemp, but uplands which have been heavily +manured make profitable yields. + +The ground for hemp is prepared as for other grain crops. The seed is +generally broadcasted for a fiber crop and then harrowed in. No +cultivation is required after seeding. + +If hemp is grown for seed, it is best to plant with a drill so that the +crop may be cultivated. The stalks after being cut are put in shocks +until they are dry. Then the seeds are threshed. Large amounts of hemp +seed are sold for caged birds and for poultry; it is also used for +paint-oils. + + +SECTION XLVII. BUCKWHEAT + +Buckwheat shares with rye and cowpeas the power to make a fairly good +crop on poor land. At the same time, of course, a full crop can be +expected only from fertile land. + +The three varieties most grown in America are the common gray, the +silver-hull, and the Japanese. The seeds of the common gray are larger +than the silver-hull, but not so large as the Japanese. The seeds from +the gray variety are generally regarded as inferior to the other two. +This crop is grown to best advantage in climates where the nights are +cool and moist. It matures more quickly than any other grain crop and is +remarkably free from disease. The yield varies from ten to forty bushels +an acre. Buckwheat does not seem to draw plant food heavily from the +soil and can be grown on the same land from year to year. + +In fertilizing buckwheat land, green manures and rich nitrogenous +fertilizers should be avoided. These cause such a luxuriant growth that +the stalks lodge badly. + +The time of seeding will have to be settled by the height of the land +and by the climate. In northern climates and in high altitudes the +seeding is generally done in May or June. In southern climates and in +low altitudes the planting may wait until July or August. The plant +usually matures in about seventy days. It cannot stand warm weather at +blooming-time, and must always be planted so that it may escape warm +weather in its blooming period and cold weather in its maturing season. +The seeds are commonly broadcasted at an average rate of four pecks to +the acre. If the land is loose and pulverized, it should be rolled. + +[Illustration: FIG. 220. BUCKWHEAT IN SHOCK] + +Buckwheat ripens unevenly and will continue to bloom until frost. +Harvesting usually begins just after the first crop of seeds have +matured. To keep the grains from shattering, the harvesting is best done +during damp or cloudy days or early in the morning while the dew is +still on the grain. The grain should be threshed as soon as it is dry +enough to go through the thresher. + +Buckwheat is grown largely for table use. The grain is crushed into a +dark flour that makes most palatable breakfast cakes. The grain, +especially when mixed with corn, is becoming popular for poultry food. +The middlings, which are rich in fats and protein, are prized for dairy +cows. + + +SECTION XLVIII. RICE + +The United States produces only about one half of the rice that it +consumes. There is no satisfactory reason for our not raising more of +this staple crop, for five great states along the Gulf of Mexico are +well adapted to its culture. + +[Illustration: FIG. 221. THRESHING RICE] + +There are two distinct kinds of rice, upland rice and lowland rice. +Upland rice demands in general the same methods of culture that are +required by other cereals, for example, oats or wheat. The growing of +lowland rice is considerably more difficult and includes the necessity +of flooding the fields with water at proper times. + +A stiff, half-clay soil with some loam is best suited to this crop. The +soil should have a clay subsoil to retain water and to give stiffness +enough to allow the use of harvesting-machinery. Some good rice soils +are so stiff that they must be flooded to soften them enough to admit of +plowing. Plow deeply to give the roots ample feeding-space. Good +tillage, which is too often neglected, is valuable. + +Careful seed-selection is perhaps even more needed for rice than for any +other crop. Consumers want kernels of the same size. Be sure that your +seed is free from red rice and other weeds. Drilling is much better +than broadcasting, as it secures a more even distribution of the seed. + +The notion generally prevails that flooding returns to the soil the +needed fertility. This may be true if the flooding-water deposits much +silt, but if the water be clear it is untrue, and fertilizers or +leguminous crops are needed to keep up fertility. Cowpeas replace the +lost soil-elements and keep down weeds, grasses, and red rice. + +Red rice is a weed close kin to rice, but the seed of one will not +produce the other. Do not allow it to get mixed and sowed with your rice +seed or to go to seed in your field. + + +SECTION XLIX. THE TIMBER CROP + +Forest trees are not usually regarded as a crop, but they are certainly +one of the most important crops. We should accustom ourselves to look on +our trees as needing and as deserving the same care and thought that we +give to our other field crops. The total number of acres given to the +growth of forest trees is still enormous, but we should each year add to +this acreage. + +Unfortunately very few forests are so managed as to add yearly to their +value and to preserve a model stand of trees. Axmen generally fell the +great trees without thought of the young trees that should at once begin +to fill the places left vacant by the fallen giants. Owners rarely study +their woodlands to be sure that the trees are thick enough, or to find +out whether the saplings are ruinously crowding one another. Disease is +often allowed to slip in unchecked. Old trees stand long after they have +outlived their usefulness. + +The farm wood-lot, too, is often neglected. As forests are being swept +away, fuel is of course becoming scarcer and more costly. Every farmer +ought to plant trees enough on his waste land to make sure of a constant +supply of fuel. The land saved for the wood-lot should be selected from +land unfit for cultivation. Steep hillsides, rocky slopes, ravines, +banks of streams--these can, without much expense or labor, be set in +trees and insure a never-ending fuel supply. + +[Illustration: FIG. 222. WOOD LOT +Before proper treatment] + +The most common enemies of the forest crop are: + +First, forest fires. The waste from forest fires in the United States is +most startling. Many of these fires are the result of carelessness or +ignorance. Most of the states have made or are now making laws to +prevent and to control such fires. + +Second, fungous diseases. The timber loss from these diseases is +exceedingly great. + +Third, insects of many kinds prey on the trees. Some strip all the +leaves from the branches. Others bore into the roots, trunk, or +branches. Some lead to a slow death; others are more quickly fatal. + +Fourth, improper grazing. Turning animals into young woods may lead to +serious loss. The animals frequently ruin young trees by eating all the +foliage. Hogs often unearth and consume most of the seeds needed for a +good growth. + +[Illustration: FIG. 223. WOOD LOT +After proper treatment] + +The handling of forests is a business just as the growing of corn is a +business. In old forests, dead and dying trees should be cut. Trees that +occupy space and yet have little commercial value should give way to +more valuable trees. A quick-growing tree, if it is equally desirable, +should be preferred to a slow grower. An even distribution of the trees +should be secured. + +In all there are about five hundred species of trees which are natives +of the United States. Probably not over seventy of these are desirable +for forests. In selecting trees to plant or to allow to grow from their +own seeding, pick those that make a quick growth, that have a steady +market value, and that suit the soil, the place of growth, and the +climate. + + +SECTION L. THE FARM GARDEN + +Every farmer needs a garden in which to grow not only vegetables but +small fruits for the home table. + +The garden should always be within convenient distance of the farmhouse. +If possible, the spot selected should have a soil of mixed loam and +clay. Every foot of soil in the garden should be made rich and mellow by +manure and cultivation. The worst soils for the home garden are light, +sandy soils, or stiff, clayey soils; but any soil, by judicious and +intelligent culture, can be made suitable. + +In laying out the garden we should bear in mind that hand labor is the +most expensive kind of labor. Hence we should not, as is commonly done, +lay off the garden spot in the form of a square, but we should mark off +for our purpose a long, narrow piece of land, so that the cultivating +tools may all be conveniently drawn by a horse or a mule. The use of the +plow and the horse cultivator enables the cultivation of the garden to +be done quickly, easily, and cheaply. + +Each vegetable or fruit should be planted in rows, and not in little +patches. Beginning with one side of the garden the following plan of +arrangement is simple and complete: two rows to corn for table use; two +to cabbages, beets, radishes, and eggplants; two to onions, peas, and +beans; two to oyster-plants, okra, parsley, and turnips; two to +tomatoes; then four on the other side can be used for strawberries, +blackberries, raspberries, currants, and gooseberries. + +[Illustration: FIG. 224. WHERE DELICIOUS GARDEN VEGETABLES GROW] + +The garden, when so arranged, can be tilled in the spring and tended +throughout the growing season with little labor and little loss of time. +In return for this odd-hour work, the farmer's family will have +throughout the year an abundance of fresh, palatable, and health-giving +vegetables and small fruits. + +The keynote of successful gardening is to stir the soil. Stir it often +with four objects in view: + + 1. To destroy weeds. + + 2. To let air enter the soil. + + 3. To enrich the soil by the action of the air. + + 4. To retain the moisture by preventing its evaporation. + + corn + corn + + cabbage beets radishes + cabbage beets eggplants + + onions peas beans + onions peas beans + + oyster-plants okra parsley parsnips + oyster-plants okra parsley parsnips + + tomatoes + tomatoes + + strawberries currants raspberries blackberries + strawberries currants raspberries blackberries + strawberries currants raspberries blackberries + strawberries currants raspberries blackberries + +[Illustration: FIG. 225. HOW TO LAY OUT THE GARDEN[1]] + +This illustration shows that practically every garden vegetable and all +the small fruits can be included in the farm garden, and all the work be +done by horse-drawn tools. + +[Footnote 1: The number of rows and arrangement of the vegetables in the +outline above are merely suggestive. They should be changed to meet the +needs and the tastes of each particular family.] + + + + +CHAPTER IX + +FEED STUFFS + +SECTION LI. GRASSES + + +Under usual conditions no farmer expects to grow live stock successfully +and economically without setting apart a large part of his land for the +growth of mowing and pasture crops. Therefore to the grower of stock the +management of grass crops is all-important. + +In planting either for a meadow or for a pasture, the farmer should mix +different varieties of grass seeds. Nature mixes them when she plants, +and Nature is always a trustworthy teacher. + +In planting for a pasture the aim should be to sow such seeds as will +give green grass from early spring to latest fall. In seeding for a +meadow such varieties should be sowed together as ripen about the same +time. + +Even in those sections of the country where it grows sparingly and where +it is easily crowded out, clover should be mixed with all grasses sowed, +for it leaves in the soil a wealth of plant food for the grasses coming +after it to feed on. Nearly every part of our country has some clover +that experience shows to be exactly suited to its soil and climate. +Study these clovers carefully and mix them with your grass seed. + +The reason for mixing clover and grass is at once seen. The true +grasses, so far as science now shows, get all their nitrogen from the +soil; hence they more or less exhaust the soil. But, as several times +explained in this book, the clovers are legumes, and all legumes are +able by means of the bacteria that live on their roots to use the free +nitrogen of the air. Hence without cost to the farmer these clovers help +the soil to feed their neighbors, the true grasses. For this reason some +light perennial legume should always be added to grass seed. + +[Illustration: FIG. 226. SINGLE PLANT OF GIANT MILLET] + +It is not possible for grasses to do well in a soil that is full of +weeds. For this reason it is always best to sow grass in fields from +which cultivated crops have just been taken. Soil which is to have grass +sowed in it should have its particles pressed together. The small grass +seeds cannot take root and grow well in land that has just been plowed +and which, consequently, has its particles loose and comparatively far +apart. On the other hand, land from which a crop of corn or cotton has +just been harvested is in a compact condition. The soil particles are +pressed well together. Such land when mellowed by harrowing makes a +splendid bed for grass seeds. A firm soil draws moisture up to the +seeds, while a mellow soil acts as a blanket to keep moisture from +wasting into the air, and at the same time allows the heated air to +circulate in the soil. + +In case land has to be plowed for grass-seeding, the plowing should be +done as far as possible in advance of the seeding. Then the plowed land +should be harrowed several times to get the land in a soft, mellow +condition. + +If the seed-bed be carefully prepared, little work on the ground is +necessary after the seeds are sowed. One light harrowing is sufficient +to cover the broadcast seeds. This harrowing should always be done as +soon as the seeds are scattered, for if there be moisture in the soil +the tiny seeds will soon sprout, and if the harrowing be done after +germination is somewhat advanced, the tender grass plants will be +injured. + +There are many kinds of pasture and meadow grasses. In New England, +timothy, red clover, and redtop are generally used for the mowing crop. +For permanent pasture, in addition to those mentioned, there should be +added white clover and either Kentucky or Canadian blue grass. In the +Southern states a good meadow or pasture can be made of orchard grass, +red clover, and redtop. For a permanent pasture in the South, Japan +clover, Bermuda, and such other local grasses as have been found to +adapt themselves readily to the climate should be added. In the Middle +States temporary meadows and pastures are generally made of timothy and +red clover, while for permanent pastures white clover and blue grass +thrive well. In the more western states the grasses previously suggested +are readily at home. Alfalfa is proving its adaptability to nearly all +sections and climates, and is in many respects the most promising grass +crop of America. + +[Illustration: FIG. 227. BERMUDA] + +It hardly ever pays to pasture meadows, except slightly, the first +season, and then only when the soil is dry. It is also poor policy to +pasture any kind of grass land early in the spring when the soil is wet, +because the tramping of animals crushes and destroys the crowns of the +plants. After the first year the sward becomes thicker and tougher, and +the grass is not at all injured if it is grazed wisely. + +[Illustration: FIG. 228. ALFALFA THE WONDERFUL +The first crop of the season is being cut and stored for winter] + +The state of maturity at which grass should be harvested to make hay of +the best quality varies somewhat with the different grasses and with the +use which is to be made of the hay. Generally speaking, it is a good +rule to cut grass for hay just as it is beginning to bloom or just after +the bloom has fallen. All grasses become less palatable to stock as they +mature and form seed. If grass be allowed to go to seed, most of the +nutrition in the stalk is used to form the seed. + +[Illustration: FIG. 229. HARVESTING ALFALFA] + +Hence a good deal of food is lost by waiting to cut hay until the seeds +are formed. + +Pasture lands and meadow lands are often greatly improved by replowing +and harrowing in order to break up the turf that forms and to admit air +more freely into the soil. The plant-roots that are destroyed by the +plowing or harrowing make quickly available plant food by their decay, +and the physical improvement of the soil leads to a thicker and better +stand. In the older sections of the country commercial fertilizer can be +used to advantage in producing hay and pasturage. If, however, clover +has just been grown on grass land or if it is growing well with the +grass, there is no need to add nitrogen. If the grass seems to lack +sufficient nourishment, add phosphoric acid and potash. However, grass +not grown in company with clover often needs dried blood, nitrate of +soda, or some other nitrogen-supplying agent. Of course it is understood +that no better fertilizer can be applied to grass than barnyard manure. + + +SECTION LII. LEGUMES + +Often land which was once thought excellent is left to grow up in weeds. +The owner says that the land is worn out, and that it will not pay to +plant it. What does "worn out" mean? Simply that constant cropping has +used up the plant food in the land. Therefore, plants on worn-out land +are too nearly starved to yield bountifully. Such wearing out is so +easily prevented that no owner ought ever to allow his land to become +poverty-stricken. But in case this misfortune has happened, how can the +land be again made fertile? + +On page 24 you learned that phosphoric acid, potash, and nitrogen are +the foods most needed by plants. "Worn out," then, to put it in +another way, usually means that a soil has been robbed of one of these +plant necessities, or of two or of all three. To make the land once more +fruitful it is necessary to restore the missing food or foods. How can +this be done? Two of these plant foods, namely, phosphoric acid and +potash, are minerals. If either of these is lacking, it can be supplied +only by putting on the land some fertilizer containing the missing food. +Fortunately, however, nitrogen, the most costly of the plant foods, can +be readily and cheaply returned to poor land. + +[Illustration: FIG. 230. ALFALFA READY FOR THE THIRD CUTTING] + +As explained on page 32 the leguminous crops have the power of drawing +nitrogen from the air and, by means of their root-tubercles, of storing +it in the soil. Hence by growing these crops on poor land the expensive +nitrogen is quickly restored to the soil, and only the two cheaper plant +foods need be bought. How important it is then to grow these leguminous +plants! Every farmer should so rotate his planting that at least once +every two or three years a crop of legumes may add to the fruitfulness +of his fields. + +Moreover these crops help land in another way. They send a multitude of +roots deep into the ground. These roots loosen and pulverize the soil, +and their decay, at the end of the growing season, leaves much humus in +the soil. Land will rarely become worn out if legumes are regularly and +wisely grown. + +From the fact that they do well in so many different sections and in so +many different climates, the following are the most useful legumes: +alfalfa, clovers, cowpeas, vetches, and soy beans. + +=Alfalfa.= Alfalfa is primarily a hay crop. It thrives in the Far West, +in the Middle West, in the North, and in the South. In fact, it will do +well wherever the soil is rich, moist, deep, and underlaid by an open +subsoil. The vast areas given to this valuable crop are yearly +increasing in every section of the United States. Alfalfa, however, +unlike the cowpea, does not take to poor land. For its cultivation, +therefore, good fertile land that is moist but not water-soaked should +be selected. + +Good farmers are partial to alfalfa for three reasons. First, it yields +a heavy crop of forage or hay. Second, being a legume, it improves the +soil. Third, one seeding lasts a long time. This length of life may, +however, be destroyed by pasturing or abusing the alfalfa. + +[Illustration: FIG. 231. SHEEP FATTENING ON ALFALFA STUBBLE] + +Alfalfa is different from most plants in this respect: the soil in which +it grows must have certain kinds of bacteria in it. These cause the +growth of tubercles on the roots. These bacteria, however, are not +always present in land that has not been planted in alfalfa. Hence if +this plant is to be grown successfully these helpful bacteria must +sometimes be supplied artificially. + +There are two very easy ways of supplying the germs. First, fine soil +from an alfalfa field may be scattered broadcast over the fields to be +seeded. Second, a small mass of alfalfa tubercle germs may be put into a +liquid containing proper food to make these germs multiply and grow; +then the seeds to be planted are soaked in this liquid in order that +the germs may fasten on the seeds. + +Before the seeds are sowed the soil should be mellowed. Over this +well-prepared land about twenty pounds of seed to the acre should be +scattered. The seed may be scattered by hand or by a seed-sower. Cover +with a light harrow. The time of planting varies somewhat with the +climate. Except where the winters are too severe the seed may be sowed +either in the spring or in the fall. In the South sow only in the fall. + +[Illustration: FIG. 232. HERD OF DAIRY CATTLE GRAZING ON ALFALFA STUBBLE] + +During the first season one mowing, perhaps more, is necessary to insure +a good stand and also to keep down the weeds. When the first blossoms +appear in the early summer, it is time to start the mower. After this +the alfalfa should be cut every two, three, or four weeks. The number of +times depends on the rapidity of growth. + +This crop rarely makes a good yield the first year, but if a good stand +be secured, the yield steadily increases. After a good stand has been +secured, a top-dressing of either commercial fertilizer or stable manure +will be very helpful. An occasional cutting-up of the sod with a disk +harrow does much good. + +=Clovers.= The different kinds of clovers will sometimes grow on hard or +poor soil, but they do far better if the soil is enriched and properly +prepared before the seed is sowed. In many parts of our country it has +been the practice for generations to sow clover seed with some of the +grain crops. Barley, wheat, oats, and rye are the crops with which +clover is usually planted, but many good farmers now prefer to sow the +seed only with other grass seed. Circumstances must largely determine +the manner of seeding. + +Crimson clover, which is a winter legume, usually does best when seeded +alone, although rye or some other grain often seems helpful to it. This +kind of clover is an excellent crop with which to follow cotton or corn. +It is most conveniently sowed at the last cultivation of these crops. + +Common red clover, which is the standard clover over most of the +country, is usually seeded with timothy or with orchard grass or with +some other of the grasses. In sowing both crimson and red clover, about +ten to fifteen pounds of seed for each acre are generally used. + +To make good pastures, white and Japan clover are favorites. White +clover does well in most parts of America, and Japan clover is +especially valuable in warm Southern climates. Both will do well even +when the soil is partly shaded, but they do best in land fully open to +the sun. + +Careful attention is required to cure clover hay well. The clover should +always be cut before it forms seed. The best time to cut is when the +plants are in full bloom. + +[Illustration: FIG. 233. CRIMSON CLOVER] + +Let the mower be started in the morning. Then a few hours later run over +the field with the tedder. This will loosen the hay and let in air and +sunshine. If the weather be fair let the hay lie until the next day, and +then rake it into rows for further drying. After being raked, the hay +may either be left in the rows for final curing or it may be put in +cocks. If the weather be unsettled, it is best to cock the hay. Many +farmers have cloth covers to protect the cocks and these often aid +greatly in saving the hay crop in a rainy season. In case the hay is put +in cocks, it should be opened for a final drying before it is housed. + +=Cowpeas.= The cowpea is an excellent soil-enricher. It supplies more +fertilizing material to turn into the soil, in a short time and at small +cost, than any other crop. Moreover, by good tillage and by the use of a +very small amount of fertilizer, the cowpea can be grown on land too +poor to produce any other crop. Its roots go deep into the soil. Hence +they gather plant food and moisture that shallow-rooted plants fail to +reach. These qualities make it an invaluable help in bringing worn-out +lands back to fertility. + +The cowpea is a warm-weather legume. In the United States it succeeds +best in the south and southwest. It has, however, in recent years been +grown as far north as Massachusetts, New York, Ohio, Michigan, and +Minnesota, but in these cold climates other legumes are more useful. +Cowpeas should never be planted until all danger of frost is past. Some +varieties make their full growth in two months; others need four months. + +There are about two hundred varieties of cowpeas. These varieties differ +in form, in the size of seed and of pod, in the color of seed and of +pod, and in the time of ripening. They differ, too, in the manner of +growth. Some grow erect; others sprawl on the ground. In selecting +varieties it is well to choose those that grow straight up, those that +are hardy, those that fruit early and abundantly, and those that hold +their leaves. The variety selected for seed should also suit the land +and the climate. + +The cowpea will grow in almost any soil. It thrives best and yields most +bountifully on well-drained sandy loams. The plant also does well on +clay soils. On light, sandy soils a fairly good crop may be made, but on +such soils, wilt and root-knot are dangerous foes. A warm, moist, +well-pulverized seed-bed should always be provided. Few plants equal the +cowpea in repaying careful preparation. + +[Illustration: FIG. 234. COWPEAS] + +If this crop is grown for hay, the method of seeding and cultivating +will differ somewhat from the method used when a seed crop is desired. +When cowpeas are planted for hay the seeds should be drilled or +broadcasted. If the seeds are small and the land somewhat rich, about +four pecks should be sowed on each acre. If the seeds are comparatively +large and the soil not so fertile, about six pecks should be sowed to +the acre. It is safer to disk in the seeds when they are sowed broadcast +than it is to rely on a harrow to cover them. In sowing merely for a +hay crop, it is a good practice to mix sorghum, corn, soy beans, or +millet with the cowpeas. The mixed hay is more easily harvested and more +easily cured than unmixed cowpea hay. Shortly after seeding, it pays to +run over the land lightly with a harrow or a weeder in order to break +any crust that may form. + +Mowing should begin as soon as the stalks and the pods have finished +growing and some of the lower leaves have begun to turn yellow. An +ordinary mower is perhaps the best machine for cutting the vines. If +possible, select only a bright day for mowing and do not start the +machine until the dew on the vines is dried. Allow the vines to remain +as they fell from the mower till they are wilted; then rake them into +windrows. The vines should generally stay in the windrows for two or +three days and be turned on the last day. They should then be put in +small, airy piles or piled around a stake that has crosspieces nailed to +it. The drying vines should never be packed; air must circulate freely +if good hay is to be made. As piling the vines around stakes is somewhat +laborious, some growers watch the curing carefully and succeed in +getting the vines dry enough to haul directly from the windrows to the +barns. Never allow the vines to stay exposed to too much sunshine when +they are first cut. If the sun strikes them too strongly, the leaves +will become brittle and shatter when they are moved. + +When cowpeas are grown for their pods to ripen, the seeds should be +planted in rows about a yard apart. From two to three pecks of seeds to +an acre should be sufficient. The growing plants should be cultivated +two or three times with a good cultivator. Cowpeas were formerly +gathered by hand, but such a method is of course slow and expensive. +Pickers are now commonly used. + +Some farmers use the cowpea crop only as a soil-enricher. Hence they +neither gather the seeds nor cut the hay, but plow the whole crop into +the soil. There is an average of about forty-seven pounds of nitrogen in +each ton of cowpea vines. Most of this valuable nitrogen is drawn by the +plants from the air. This amount of nitrogen is equal to that contained +in 9500 pounds of stable manure. In addition each ton of cowpea vines +contains ten pounds of phosphoric acid and twenty-nine pounds of potash. + +There is danger in plowing into the soil at one time any bountiful green +crop like cowpeas. As already explained on page 10, a process +called capillarity enables moisture to rise in the soil as plants need +it. Now if a heavy cowpea crop or any other similar crop be at one +plowing turned into the soil, the soil particles will be so separated as +to destroy capillarity. Too much vegetation turned under at once may +also, if the weather be warm, cause fermentation to set in and "sour the +land." Both of these troubles may be avoided by cutting up the vines +with a disk harrow or other implement before covering them. + +The custom of planting cowpeas between the rows at the last working of +corn is a good one, and wherever the climate permits this custom should +be followed. + +=Vetches.= The vetches have been rapidly growing in favor for some +years. Stock eat vetch hay greedily, and this hay increases the flow of +milk in dairy animals and helps to keep animals fat and sleek. Only two +species of vetch are widely grown. These are the tare, or spring vetch, +and the winter, or hairy, vetch. Spring vetch is grown in comparatively +few sections of our country. It is, however, grown widely in England and +northern continental Europe. What we say here will be confined to hairy +vetch. + +After a soil has been supplied with the germs needed by this plant, the +hairy vetch is productive on many different kinds of soil. The plant is +most vigorous on fertile loams. By good tillage and proper fertilization +it may be forced to grow rather bountifully on poor sandy and clay +loams. Acid or wet soils are not suited to vetch. Lands that are too +poor to produce clovers will frequently yield fair crops of vetch. If +this is borne in mind, many poor soils may be wonderfully improved by +growing on them this valuable legume. + +[Illustration: FIG. 235. VETCH] + +Vetch needs a fine well-compacted seed-bed, but it is often sowed with +good results on stubble lands and between cotton and corn rows, where it +is covered by a cultivator or a weeder. + +The seeds of the vetch are costly and are brought chiefly from Germany, +where this crop is much prized. The pods ripen so irregularly that they +have to be picked by hand. + +In northern climates early spring sowing is found most satisfactory. In +southern climates the seeding is best done in the late summer or early +fall. As the vetch vines have a tendency to trail on the ground, it is +wisest to plant with the vetch some crop like oats, barley, rye, or +wheat. These plants will support the vetch and keep its vines from being +injured by falling on the ground. Do not use rye with vetch in the +South. It ripens too early to be of much assistance. If sowed with oats +the seeding should be at the rate of about twenty or thirty pounds of +vetch and about one and a half or two bushels of oats to the acre. Vetch +is covered in the same way as wheat and rye. + +Few crops enrich soil more rapidly than vetch if the whole plant is +turned in. It of course adds nitrogen to the soil and at the same time +supplies the soil with a large amount of organic matter to decay and +change to humus. As the crop grows during the winter, it makes an +excellent cover to prevent washing. Many orchard-growers of the +Northwest find vetch the best winter crop for the orchards as well as +for the fields. + +=Soy, or Soja, Bean.= In China and Japan the soy bean is grown largely +as food for man. In the United States it is used as a forage plant and +as a soil-improver. It bids fair to become one of the most popular of +the legumes. Like the cowpea, this bean is at home only in a warm +climate. Some of the early-ripening varieties have, however, been +planted with fair success in cold climates. + +While there are a large number of varieties of the soy bean, only about +a dozen are commonly grown. They differ mainly in the color, size, and +shape of the seeds, and in the time needed for ripening. Some of the +varieties are more hairy than others. + +Soy beans may take many places in good crop-rotations, but they are +unusually valuable in short rotations with small grains. The grains can +be cut in time for the beans to follow them, and in turn the beans can +be harvested in the early fall and make way for another grain crop. + +It should always be remembered that soy beans will not thrive unless the +land on which they are to grow is already supplied, or is supplied at +the time of sowing, with bean bacteria. + +[Illustration: FIG. 236. CHINESE SOY BEANS] + +The plant will grow on many different kinds of soil, but it needs a +richer soil than the cowpea does. As the crop can gather most of its own +nitrogen, it generally requires only the addition of phosphoric acid and +potash for its growth on poor land. When the first crop is seeded, apply +to each acre four hundred pounds of a fertilizing mixture which contains +about ten per cent of phosphoric acid, four per cent of potash, and from +one to two per cent of nitrogen. + +If the crop is planted for hay or for grazing, mellow the ground well, +and then broadcast or drill in closely about one and a half bushels of +seed to each acre. Cover from one to two inches deep, but never allow a +crust to form over the seed, for the plant cannot break through a crust +well. When the beans are planted for seeds, a half bushel of seed to the +acre is usually sufficient. The plants should stand in the rows from +four to six inches apart, and the rows should be from thirty to forty +inches from one another. Never plant until the sun has thoroughly warmed +the land. The bean may be sowed, however, earlier than cowpeas. A most +convenient time is just after corn is planted. The rows should be +cultivated often enough to keep out weeds and grass and to keep a good +dust mulch, but the cultivation must be shallow. + +[Illustration: FIG. 237. SOY BEANS] + +As soy beans are grown for hay and also for seed, the harvesting will, +as with the other legumes, be controlled by the purpose for which the +crop was planted. In harvesting for a hay crop it is desirable to cut +the beans after the pods are well formed but before they are fully +grown. If the cutting is delayed until the pods are ripe, the fruit will +shatter badly. There is a loss, too, in the food value of the stems if +the cutting is late. The ordinary mowing-machine with a rake attached is +generally the machine used for cutting the stalks. The leaves should be +most carefully preserved, for they contain much nourishment for stock. + +[Illustration: FIG. 238. SOY BEANS IN CORN] + +Whenever the beans are grown for seeds, harvesting should begin when +three fourths of the leaves have fallen and most of the pods are ripe. +Do not wait, however, until the pods are so dry that they have begun to +split and drop their seeds. A slight amount of dampness on the plants +aids the cutting. The threshing may be done with a flail, with +pea-hullers, or with a grain-threshing machine. + +The beans produce more seed to the acre than cowpeas do. Forty bushels +is a high yield. The average yield is between twenty and thirty bushels. + + DESCRIPTIVE TABLE + + ADAPTATION AS +Crop FOOD FOR ANIMALS LIFE REMARKS + +Alfalfa Hay Perennial All animals like it; hogs + eat it even when it is dry. +Red clover Hay and pasture Perennial Best of the clovers for hay. +Alsike clover Hay and pasture Perennial Seeds itself for twenty + years.

The general rule is, poor +stock, poor people. All the prosperous nations of the globe, especially +the grain-growing nations, get a large share of their wealth from +raising improved stock. The stock bred by these nations is now, however, +very different from the stock raised by the same nations years ago. As +soon as man began to progress in the art of agriculture he became +dissatisfied with inferior stock. He therefore bent his energies to +raise the standard of excellence in domestic animals. + +By slow stages of animal improvement the ugly, thin-flanked wild boar of +early times has been transformed into the sleek Berkshire or the +well-rounded Poland-China. In the same manner the wild sheep of the Old +World have been developed into wool and mutton breeds of the finest +excellence. By constant care, attention, and selection the thin, +long-legged wild ox has been bred into the bounteous milk-producing +Jerseys and Holsteins or into the Shorthorn mountains of flesh. From the +small, bony, coarse, and shaggy horse of ancient times have descended +the heavy Norman, or Percheron, draft horse and the fleet Arab courser. + +The matter of meat-production is one of vital importance to the human +race, for animal food must always supply a large part of man's ration. + +Live stock of various kinds consume the coarser foods, like the grasses, +hays, and grains, which man cannot use. As a result of this consumption +they store in their bodies the exact substances required for building up +the tissues of man's body. + +When the animal is used by man for food, one class of foods stored away +in the animal's body produces muscle; another produces fat, heat, and +energy. The food furnished by the slaughter of animals seems necessary +to the full development of man. It is true that the flesh of an animal +will not support human life so long as would the grain that the animal +ate while growing, but it is also true that animal food does not require +so much of man's force to digest it. Hence the use of meat forces a part +of man's life-struggle on the lower animal. + +When men feed grain to stock, the animals receive in return power and +food in their most available forms. Men strengthen the animal that they +themselves may be strengthened. One of the great questions, then, for +the stock-grower's consideration is how to make the least amount of food +fed to animals produce the most power and flesh. + + +SECTION LIII. HORSES + +While we have a great many kinds of horses in America, horses are not +natives of this country. Just where wild horses were first tamed and +used is not certainly known. It is believed that in early ages the horse +was a much smaller animal than it now is, and that it gradually attained +its present size. Where food was abundant and nutritious and the climate +mild and healthful, the early horses developed large frames and heavy +limbs and muscles; on the other hand, where food was scarce and the +climate cold and bleak, the animals remained as dwarfed as the ponies of +the Shetland Islands. + +[Illustration: FIG. 239. THE FAMILY PET] + +One of the first records concerning the horse is found in Genesis xlix, +17, where Jacob speaks of "an adder that biteth the horse heels." +Pharaoh took "six hundred chosen chariots" and "with all the horses and +chariots" pursued the Israelites. The Greeks at first drove the horse +fastened to a rude chariot; later they rode on its back, learning to +manage the animal with voice or switch and without either saddle or +bridle. This thinking people soon invented the snaffle bit, and both +rode and drove with its aid. The curb bit was a Roman invention. Shoeing +was not practiced by either Greeks or Romans. Saddles and harnesses were +at first made of skins and sometimes of cloth. + +Among the Tartars of middle and northern Asia and also among some other +nations, mare's milk and the flesh of the horse are used for food. Old +and otherwise worthless horses are regularly fattened for the meat +markets of France and Germany. Various uses are made of the different +parts of a horse's body. The mane and tail are used in the manufacture +of mattresses, and also furnish a haircloth for upholstering; the skin +is tanned into leather; the hoofs are used for glue, and the bones for +making fertilizer. + +[Illustration: FIG. 240. PERCHERON HORSE (A DRAFT TYPE)] + +Climate, food, and natural surroundings have all aided in producing +changes in the horse's form, size, and appearance. The varying +circumstances under which horses have been raised have given rise to the +different breeds. In addition, the masters' needs had much to do in +developing the type of horses wanted. Some masters desired work horses, +and kept the heavy, muscular, stout-limbed animals; others desired +riding and driving horses, so they saved for their use the light-limbed, +angular horses that had endurance and mettle. The following table gives +some of the different breeds and the places of their development: + +[Illustration: FIG. 241. +Diagram shows the proper shape of the fore and hind legs of a horse. +When the straight lines divide the legs equally, the leg action is +straight and regular] + + I. _Draft, or Heavy, Breeds_ + + 1. Percheron, from the province of Perche, France. + 2. French Draft, developed in France. + 3. Belgian Draft, developed by Belgian farmers. + 4. Clydesdale, the draft horse of Scotland. + 5. Suffolk Punch, from the eastern part of England. + 6. English Shire, also from the eastern part of England. + + II. _Carriage, or Coach, Breeds_ + + 1. Cleveland Bay, developed in England. + 2. French Coach, the gentleman's horse of France. + 3. German Coach, from Germany. + 4. Oldenburg Coach, Oldenburg, Germany. + 5. Hackney, the English high-stepper. + + III. _Light, or Roadster, Breeds_ + + 1. American Trotter, developed in America. + 2. Thoroughbred, the English running horse. + 3. American Saddle Horse, from Kentucky and Virginia. + +There is a marked difference in the form and type of these horses, and +on this difference their usefulness depends. + +[Illustration: FIG. 242. WIDE HOCK +This horse stands great strains and is not fatigued easily] + +[Illustration: FIG. 243. NARROW HOCK +This horse becomes exhausted very easily] + +The draft breeds have short legs, and hence their bodies are +comparatively close to the ground. The depth of the body should be about +the same as the length of leg. All draft horses should have upright +shoulders, so as to provide an easy support for the collar. The hock +should be wide, so that the animal shall have great leverage of muscle +for pulling. A horse having a narrow hock is not able to draw a heavy +load and is easily exhausted and liable to curb-diseases (see Figs. 242 +and 243). + +[Illustration: FIG. 244. THE ROADSTER TYPE] + +The legs of all kinds of horses should be straight; a line dropped from +the point of the shoulder to the ground should divide the knees, canon, +fetlock, and foot into two equal parts. When the animal is formed in +this way the feet have room to be straight and square, with just the +breadth of a hoof between them (Fig. 241). + +Roadsters are lighter in bone and less heavily muscled; their legs are +longer than those of the draft horses and, as horsemen say, more +"daylight" can be seen under the body. The neck is long and thin, but +fits nicely into the shoulders. The shoulders are sloping and long and +give the roadster ability to reach well out in his stride. The head is +set gracefully on the neck and should be carried with ease and +erectness. + +Every man who is to deal with horses ought to become, by observation and +study, an expert judge of forms, qualities, types, defects, and +excellences. + +[Illustration: FIG. 245. SIDE VIEW OF LEGS +The diagram shows how the straight lines ought to cross the legs of a +properly shaped horse] + +The horse's foot makes an interesting study. The horny outside protects +the foot from mud, ice, and stones. Inside the hoof are the bones and +gristle that serve as cushions to diminish the shock received while +walking or running on hard roads or streets. When shoeing the horse the +frog should not be touched with the knife. It is very seldom that any +cutting need be done. Many blacksmiths do not know this and often +greatly injure the foot. + +Since the horse has but a small stomach, the food given should not be +too bulky. In proportion to the horse's size, its grain ration should be +larger than that of other animals. Draft horses and mules, however, can +be fed a more bulky ration than other horses, because they have larger +stomachs and consequently have more room to store food. + +[Illustration: FIG. 246. HOW TO MEASURE A HORSE] + +The horse should be groomed every day. This keeps the pores of the skin +open and the hair bright and glossy. When horses are working hard, the +harness should be removed during the noon hour. During the cool seasons +of the year, whenever a horse is wet with sweat, it should on stopping +work, or when standing for awhile, be blanketed, for the animal is as +liable as man to get cold in a draft or from moisture evaporating +rapidly from its skin. + + EXERCISE + + If the pupil will take an ordinary tape measure, he can make some + measurements of the horse that will be very interesting as well as + profitable. Let him measure: + + 1. The height of the horse at the withers, 1 to 1. + 2. The height of the horse at croup, 2 to 2. + 3. Length of shoulder, 1 to 3. + 4. Length of back, 4. + 5. Length of head, 5. + 6. Depth of body, 6 to 6. + 7. Daylight under body, 7 to 7. + 8. Distance from point of shoulder to quarter, 3 to 3. + 9. Width of forehead. + 10. Width between hips. + + NOTE. Many interesting comparisons can be made (1) by + measuring several horses; (2) by studying the proportion between + parts of the same horse. + + PROPORTIONS OF A HORSE + + 1. How many times longer is the body than the head? Do you get the + same result from different horses? + + 2. How does the height at the withers compare with the height at + the croup? + + 3. How do these compare with the distance from quarter to shoulder? + + 4. How does the length of the head compare with the thickness of + the body and with the open space, or "daylight," under the body? + + +SECTION LIV. CATTLE + +All farm animals were once called _cattle_; now this term applies only +to beef and dairy animals--neat cattle. + +Our improved breeds are descended from the wild ox of Europe and Asia, +and have attained their size and usefulness by care, food, and +selection. The uses of cattle are so familiar that we need scarcely +mention them. Their flesh is a part of man's daily food; their milk, +cream, butter, and cheese are on most tables; their hides go to make +leather, and their hair for plaster; their hoofs are used for glue, and +their bones for fertilizers, ornaments, buttons, and many other +purposes. + +[Illustration: FIG. 247. A PRIZE-WINNER] + +There are two main classes of cattle--beef breeds and dairy breeds. The +principal breeds of each class are as follows: + + I. _Beef Breeds_ + + 1. Aberdeen-Angus, bred in Scotland, and often called _doddies_. + 2. Galloway, from Scotland. + 3. Shorthorn, an English breed of cattle. + 4. Hereford, also an English breed. + 5. Sussex, from the county of Sussex, England. + + II. _Dairy Breeds_ + + 1. Jersey, from the Isle of Jersey. + 2. Guernsey, from the Isle of Guernsey. + 3. Ayrshire, from Scotland. + 4. Holstein-Frisian, from Holland and Denmark. + 5. Brown Swiss, from Switzerland. + +Other breeds of cattle are Devon, Dutch Belted, Red-Polled, Kerry, and +West Highland. + +In general structure there is a marked difference between the beef and +dairy breeds. This is shown in Figs. 248, 249. The beef cow is square, +full over the back and loins, and straight in the back. The hips are +covered evenly with flesh, the legs full and thick, the under line, or +stomach line, parallel to the back line, and the neck full and short. +The eye should be bright, the face short, the bones of fine texture, and +the skin soft and pliable. + +[Illustration: FIG. 248. ABERDEEN-ANGUS COW (A BEEF TYPE)] + +The dairy cow is widely different from the beef cow. She shows a decided +wedge shape when you look at her from front, side, or rear. The back +line is crooked, the hip bones and tail bone are prominent, the thighs +thin and poorly fleshed; there is no breadth to the back, as in the beef +cow, and little flesh covers the shoulders; the neck is long and thin. + +The udder of the dairy cow is most important. It should be full but not +fleshy, be well attached behind, and extend well forward. The larger the +udder the more milk will be given. + +The skin of the dairy cow, like that of the beef breeds, should be soft +and pliable and the bones fine-textured. + +=The Dairy Type.= Because of lack of flesh on the back, loins, and +thighs, the cow of the dairy type is not profitably raised for beef, nor +is the beef so good as that of the beef types. This is because in the +dairy-animal food goes to produce milk rather than beef. In the same way +the beef cow gives little milk, since her food goes rather to fat than +to milk. For the same reasons that you do not expect a plow horse to win +on the race track, you do not expect a cow of the beef type to win +premiums as a milker. + +[Illustration: FIG. 249. JERSEY COW (A DAIRY TYPE)] + +"Scrub" cattle are not profitable. They mature slowly and consequently +consume much food before they are able to give any return for it. Even +when fattened, the fat and lean portions are not evenly distributed, +and "choice cuts" are few and small. + +By far the cheapest method of securing a healthy and profitable herd of +dairy or beef cattle is to save only the calves whose sires are +pure-bred animals and whose mothers are native cows. In this way farmers +of even little means can soon build up an excellent herd. + +=Improving Cattle.= The fact that it is not possible for every farmer to +possess pure-bred cattle is no reason why he should not improve the +stock he has. He can do this by using pure-bred sires that possess the +qualities most to be desired. Scrub stock can be quickly improved by the +continuous use of good sires. It is never wise to use grade, or +cross-bred, sires, since the best qualities are not fixed in them. + +[Illustration: FIG. 250. HEAD OF A GALLOWAY COW] + +Moreover, it is possible for every farmer to determine exactly the +producing-power of his dairy cows. When the cows are milked, the milk +should be weighed and a record kept. If this be done, it will be found +that some cows produce as much as five hundred, and some as much as ten +hundred, gallons a year, while others produce not more than two or three +hundred gallons. If a farmer kills or sells his poor cows and keeps his +best ones, he will soon have a herd of only heavy milkers. Ask your +father to try this plan. Read everything you can find about taking care +of cows and improving them, and then start a herd of your own. + +=Conclusions.= (1) A cow with a tendency to get fat is not profitable +for the dairy. (2) A thin, open, angular cow will make expensive beef. +(3) "The sire is half the herd." This means that a good sire is +necessary to improve a herd of cattle. The improvement from scrubs +upward is as follows: the first generation is one-half pure; the second +is three-fourths pure; the third is seven-eighths pure; the fourth is +fifteen-sixteenths pure, etc. (4) By keeping a record of the quantity +and quality of milk each cow gives you can tell which are profitable to +raise from and which are not. (5) Good food, clean water, kindness, and +care are necessary to successful cattle-raising. + +[Illustration: FIG. 251. HOLSTEIN COW] + +The ownership of a well-bred animal usually arouses so much pride in the +owner that the animal receives all the care that it merits. The watchful +care given to such an animal leads to more thought of the other animals +on the farm, and often brings about the upbuilding of an entire herd. + + +SECTION LV. SHEEP + +The sheep was perhaps the first animal domesticated by man, and to-day +the domesticated sheep is found wherever man lives. It is found +domesticated or wild in almost every climate, and finds means to thrive +where other animals can scarcely live; it provides man with meat and +clothing, and is one of the most profitable and most easily cared-for of +animals. + +[Illustration: FIG. 252. A YOUNG SHEPHERD] + +Sheep increase so rapidly, mature at such an early age, and have flesh +so wholesome for food that nearly every farm should have its flock. +Another consideration that may be urged in favor of sheep-raising is +that sheep improve the land on which they are pastured. + +Sheep are docile and easily handled, and they live on a greater +diversity of food and require less grain than any other kind of live +stock. In mixed farming there is enough food wasted on most farms to +maintain a small flock of sheep. + +[Illustration: FIG. 253. SHEEP HAVE LONG BEEN CALLED THE +GOLDEN-HOOFED ANIMALS] + +Sheep may be divided into three classes: + + I. _Fine-Wooled Breeds_ + + 1. American Merino. + 2. Delaine Merino. + 3. Rambouillets. + 4. Hampshire Down. + 5. Oxford Down. + 6. Cheviot. + + II. _Medium-Wooled Breeds_ + + 1. Southdown. + 2. Shropshire. + 3. Horned Dorset. + + III. _Long-Wooled Breeds_ + + 1. Leicester. + 2. Lincoln. + 3. Cotswold. + +[Illustration: FIG. 254. IN THE PASTURE] + +The first group is grown principally for wool, and mutton is secondary; +in the second group, mutton comes first and wool second; in the third +group both are important considerations. Wool is nature's protection for +the sheep. Have you ever opened the fleece and observed the clean skin +in which the fibers grow? These fibers, or hairs, are so roughened that +they push all dirt away from the skin toward the outside of the fleece. + +Wool is valuable in proportion to the length and evenness of the fiber +and the density of the fleece. + + EXERCISE + + 1. How many pounds ought a fleece of wool to weigh? + 2. Which makes the better clothing, coarse or fine wool? + 3. Why are sheep washed before being sheared? + 4. Does cold weather trouble sheep? wet weather? + + + +SECTION LVI. SWINE + +The wild boar is a native of Europe, Asia, and Africa. The wild hogs are +the parents from which all our domestic breeds have sprung. In many +parts of the world the wild boar is still found. These animals are +active and powerful, and as they grow older are fierce and dangerous. In +their wild state they seek moist, sandy, and well-wooded places, close +to streams of water. Their favorite foods are fruits, grass, and roots, +but when pressed by hunger they will eat snakes, worms, and even higher +animals, like birds, fowls, and fish. + +[Illustration: FIG. 255. WHICH WILL YOU RAISE?] + +Man captured some of these wild animals, fed them abundant and +nutritious food, accustomed them to domestic life, selected the best of +them to raise from, and in the course of generations developed our +present breeds of hogs. The main changes brought about in hogs were +these: the legs became shorter, the snout and neck likewise shortened, +the shoulders and hams increased their power to take on flesh, and the +frame was strengthened to carry the added burden of flesh. As the animal +grew heavier it roamed less widely, and as it grew accustomed to man its +temper became less fierce. + +[Illustration: FIG. 256. A PAIR OF PORKERS] + +Meat can be more cheaply obtained from hogs than from any other animal. +When a hog is properly fed and cared for it will make the farmer more +money in proportion to cost than any other animal on the farm. + +The most profitable type of hog has short legs, small bones, straight +back and under line, heavy hams, small well-dished head, and heavy +shoulders. The scrub and "razorback" hogs are very unprofitable, and +require an undue amount of food to produce a pound of gain. It requires +two years to get the scrub to weigh what a well-bred pig will weigh +when nine months old. Scrub hogs can be quickly changed in form and type +by the use of a pure-bred sire. + +A boy whose parents were too poor to send him to college once decided to +make his own money and get an education. He bought a sow and began to +raise pigs. He earned the food for the mother and her pigs. His hogs +increased so rapidly that he had to work hard to keep them in food. By +saving the money he received from the sale of his hogs he had enough to +keep him two years in college. Suppose you try his plan, and let the hog +show you how fast it can make money. + +[Illustration: FIG. 257. A GOOD TYPE] + +We have several breeds of swine. The important ones are: + + I. _Large Breeds_ + + 1. Chester White. + 2. Improved Yorkshire. + 3. Tamworth. + + II. _Medium Breeds_ + + 1. Berkshire. + 2. Poland-China. + 3. Duroc-Jersey. + 4. Cheshire. + + III. _Small Breeds_ + + 1. Victoria. + 2. Suffolk. + 3. Essex. + 4. Small Yorkshire. + +Hogs will be most successfully raised when kept as little as possible in +pens. They like the fields and the pasture grass, the open air and the +sunshine. Almost any kind of food can be given them. Unlike other stock, +they will devour greedily and tirelessly the richest feeding-stuffs. + +The most desirable hog to raise is one that will produce a more or less +even mixture of fat and lean. Where only corn is fed, the body becomes +very fat and is not so desirable for food as when middlings, tankage, +cowpeas, or soy beans are added as a part of the ration. + +[Illustration: FIG. 258. DINNER IS OVER] + +When hogs are kept in pens, cleanliness is most important, for only by +cleanliness can disease be avoided. + + +SECTION LVII. FARM POULTRY + +Our geese, ducks, turkeys, and domestic hens are all descendants of wild +fowls, and are more or less similar to them in appearance. + +The earliest recorded uses of fowls were for food, for fighting, and for +sacrifice. To-day the domestic fowl has four well-defined +uses--egg-production, meat-production, feather-production, and +pest-destruction. + +[Illustration: STANDARD-BRED FOWLS +Barred Plymouth Rocks, male and female; White Wyandottes, female and +male] + +Hens of course produce most of our eggs. Some duck eggs are sold for +table use. Goose and duck body-feathers bring good prices. As +pest-destroyers turkeys and chickens are most useful. They eat large +numbers of bugs and worms that are harmful to crops. A little proper +attention would very largely increase the already handsome sum derived +from our fowls. They need dry, warm, well-lighted, and tidily kept +houses. They must have, if we want the best returns, an abundant supply +of pure water and a variety of nutritious foods. In cold, rainy, or +snowy weather they should have a sheltered yard, and in good weather +should be allowed a range wide enough to give them exercise. Their +bodies and their nests must be protected from every form of vermin. + +For eggs, the Leghorn varieties are popular. Some hens of this breed +have been known to lay more than two hundred eggs in a year. Specially +cared-for flocks have averaged eleven or even twelve dozen eggs a year. +Farm flocks of ordinary breeds average less than eight dozen. Other +excellent egg breeds are the Spanish, Andalusian, and Minorca. + +[Illustration: FIG. 259. COCK] + +The principal so-called meat breeds are the Brahma, Cochin, and +Langshan. These are very large, but rather slow-growing fowls, and are +not noted as layers. They are far less popular in America, even as +meat-producers, than the general-purpose breeds. + +The Plymouth Rock, Wyandotte, Rhode Island Red, and Orpington are the +leading general-purpose breeds. They are favorites because they are at +once good-sized, good layers, tame, and good mothers. The chicks of +these breeds are hardy and thrifty. In addition to these breeds, there +are many so-called fancy breeds that are prized for their looks rather +than for their value. Among these are the Hamburg, Polish, Sultan, +Silkie, and the many Bantam breeds. + +The leading duck breeds are the Pekin, Aylesbury, Indian Runner, +Muscovy, Rouen, and Cayuga. The principal varieties of geese are the +Toulouse, Emden, Chinese, and African. + +Among the best breeds of turkeys are the Bronze, White Holland, +Narragansett, Bourbon, Slate, and Buff. + +Geese, ducks, and turkeys are not so generally raised as hens, but there +is a constant demand at good prices for these fowls. + +[Illustration: FIG. 260. BROODER] + +The varieties of the domestic hen are as follows: + + I. _Egg Breeds_ + + 1. Leghorn. + 2. Minorca. + 3. Spanish. + 4. Blue Andalusian. + 5. Anconas. + + II. _Meat Breeds_ + + 1. Brahma. + 2. Cochin. + 3. Langshan. + 4. Dorking. + 5. Cornish. + + III. _General-Purpose Breeds_ + + 1. Plymouth Rock. + 2. Wyandotte. + 3. Rhode Island Red. + 4.

INCUBATOR] + +As the price of both eggs and fowls is steadily advancing, a great many +people are now raising fowls by means of an incubator for hatching, and +a brooder as a substitute for the mother hen. + +The use of the incubator is extending each year and is now almost +universal where any considerable number of chicks are to be hatched. +Doubtless it will continue to be used wherever poultry-production is +engaged in on a large scale. + +The brooder is employed to take care of the chickens as soon as they +leave the incubator. + + +SECTION LVIII. BEE CULTURE + +Stock-raisers select breeds that are best adapted to their needs. +Plant-growers exercise great care in their choice of plants, selecting +for each planting those best suited to the conditions under which they +are to be grown. Undoubtedly a larger yield of honey could be had each +year if similar care were exercised in the selection of the breed of +bees. + +[Illustration: FIG. 263. A CARNIOLAN WORKER] + +To prove this, one has only to compare the yield of two different kinds. +The common East Indian honey bee rarely produces more than ten or twelve +pounds to a hive, while the Cyprian bee, which is a most industrious +worker, has a record of one thousand pounds in one season from a single +colony. This bee, besides being industrious when honey material is +plentiful, is also very persevering when such material is hard to find. +The Cyprians have two other very desirable qualities. They stand the +cold of winter well and stoutly defend their hives against robber bees +and other enemies. + +The Italian is another good bee. This variety was brought into the +United States in 1860. While the yield from the Italian is somewhat less +than from the Cyprian, the Italian bees produce a whiter comb and are a +trifle more easily managed. + +The common black or brown bee is found wild and domesticated throughout +the country. When honey material is abundant, these bees equal the +Italians in honey-production, but when the season is poor, they fall far +short in the amount of honey produced. + +The purchase of a good Cyprian or Italian hive will richly repay the +buyer. Such a colony will cost more at the outset than an ordinary +colony, but will soon pay for its higher cost by greater production. + +[Illustration: FIG. 264. A CARNIOLAN DRONE] + +A beehive in the spring contains one queen, several hundred drones, and +from thirty-five to forty thousand workers. The duty of the queen is to +lay all the eggs that are to hatch the future bees. This she does with +untiring industry, often laying as many as four thousand in twenty-four +hours. + +The worker bees do all the work. Some of them visit the flowers, take up +the nectar into the honey-sac, located in their abdomens, and carry it +to the hive. They also gather pollen in basketlike cavities in their +hind legs. Pollen and nectar are needed to prepare food for the young +bees. In the hive other workers create a breeze by buzzing with their +wings and produce heat by their activity--all to cause the water to +evaporate from the nectar and to convert it into honey before it is +sealed up in the comb. After a successful day's gathering you may often +hear these tireless workers buzzing till late into the night or even all +through the night. + +You know that the bees get nectar from the flowers of various plants. +Some of the chief honey plants are alfalfa, buckwheat, horsemint, +sourwood, white sage, wild pennyroyal, black gum, holly, chestnut, +magnolia, and the tulip tree. The yield of honey may often be increased +by providing special pasturage for the bees. The linden tree, for +example, besides being ornamental and valuable for timber, produces a +most bee-inviting flower. Vetch, clover, and most of the legumes and +mints are valuable plants to furnish pasture for bees. Catnip may be +cultivated for the bees and sold as an herb as well. + +[Illustration: FIG. 265. A CARNIOLAN QUEEN] + +In spraying fruit trees to prevent disease you should always avoid +spraying when the trees are in bloom, since the poison of the spray +seriously endangers the lives of bees. + +The eggs laid by the queen, if they are to produce workers, require +about twenty-one days to bring forth the perfect bee. The newly hatched +bee commences life as a nurse. When about ten days old it begins to try +its wings in short flights, and a few days later it begins active work. +The life of a worker bee in the busy season is only about six weeks. You +may distinguish young exercising bees from real workers by the fact that +they do not fly directly away on emerging from the hive, but circle +around a bit in order to make sure that they can recognize home again, +since they would receive no cordial welcome if they should attempt to +enter another hive. They hesitate upon returning from even these short +flights, to make sure that they are in front of their own door. + +[Illustration: FIG. 266. GOOD FORM OF HIVE] + +There are several kinds of enemies of the bee which all beekeepers +should know. One of these is the robber bee, that is, a bee from another +colony attempting to steal honey from the rightful owners, an attempt +often resulting in frightful slaughter. Much robbery can be avoided by +clean handling; that is, by leaving no honey about to cultivate a taste +for stolen sweets. The bee moth is another serious enemy. The larva of +the moth feeds on the wax. Keep the colonies of bees strong so that they +may be able to overcome this moth. + +[Illustration: FIG. 267. ANTI-ROBBING ENTRANCE +_st_, stationary piece; _s_, slide; _p_, pin, or stop] + +Queenless or otherwise weak colonies should be protected by a narrow +entrance that admits only one bee at a time, for such a pass may be +easily guarded. Fig. 267 shows a good anti-robbery entrance which may be +readily provided for every weak colony. Mice may be kept out by +tin-lined entrances. The widespread fear of the kingbird seems +unfounded. He rarely eats anything but drones, and few of them. This is +also true of the swallow. Toads, lizards, and spiders are, however, true +enemies of the honeybee. + + EXERCISE + + Can you recognize drones, workers, and queens? Do bees usually + limit their visits to one kind of blossom on any one trip? What + effect has the kind of flower on the flavor of the honey produced? + What kinds of flowers should the beekeeper provide for his bees? Is + the kingbird really an enemy to the bee? + + +SECTION LIX. WHY WE FEED ANIMALS + +In the first place, we give various kinds of feed stuffs to our animals +that they may live. The heart beats all the time, the lungs contract and +expand, digestion is taking place, the blood circulates through the +body--something must supply force for these acts or the animal dies. +This force is derived from food. + +In the next place, food is required to keep the body warm. Food in this +respect is fuel, and acts in the same way that wood or coal does in the +stove. Our bodies are warm all the time, and they are kept warm by the +food we eat at mealtime. + +Then, in the third place, food is required to enable the body to +enlarge--to grow. If you feed a colt just enough to keep it alive and +warm, there will be no material present to enable it to grow; hence you +must add enough food to form bone and flesh and muscle and hair and fat. + +In the fourth place, we feed to produce strength for work. An animal +poorly fed cannot do so much work at the plow or on the road as one that +receives all the food needed. + +Both food and the force produced by it result from the activity of +plants. By means of sunlight and moisture a sprouting seed, taking out +of the air and soil different elements, grows into a plant. Then, just +as the plant feeds on the air and soil to get its growth, so the animal +feeds on the plant, to get its growth. Hence, since our animals feed +upon plants, we must find out what is in plants in order to know what +animal food consists of. + +Plants contain protein, carbohydrates, fat, mineral matter, water, and +vitamins. You have seen protein compounds like the white of an egg, lean +meat, or the gluten of wheat. The bodies of plants do not contain very +much protein. On the other hand, all plant seeds contain a good deal of +this substance. Animals make use of protein to form new blood, muscles, +and organs. Because of the quality of protein, milk is the best food for +children and young animals. + +The protein in some foods is of poor quality. To insure a well-balanced +supply of protein a variety in foods is desirable. Do not rely on a +single kind of mill feed, but combine several kinds, such as cotton-seed +meal, linseed meal, wheat bran and middlings, gluten, and similar grain +by-products. Tankage for young pigs and meat scraps for chickens are +high-grade proteins and are of animal origin. + +It is no less important to get the necessary vitamins--those mysterious +substances that keep the body healthy and promote growth and well-being. +Scientists claim that many diseases are food-deficiency diseases--the +body gets out of order because these peculiar vitamins are lacking in +the food. Children require about one or two quarts of milk a day, fresh +fruits, cereal breakfast foods, leafy vegetables as salads, and cooked +vegetables. + +Farm animals require the vitamins also. The legume pasture or hay, milk, +grain concentrates when supplied in variety, pasture grass, and green +forage crops are basic foods for farm animals. Very young animals should +have milk also. + +Let us next consider the carbohydrates. Sometimes the words _starchy +foods_ are used to describe the carbohydrates. You have long known +forms of these in the white material of corn and of potatoes. The +carbohydrates are formed of three elements--carbon, oxygen, and +hydrogen. The use of these carbohydrates is to furnish to animal bodies +either heat or energy or to enable them to store fat. + +In the next place, let us look at the fat in plant food. This consists +of the oil stored up in the seeds and other parts of the plant. The +grains contain most of the oil. Fat is used by the animal to make heat +and energy or to be stored away in the body. + +The next animal food in the plant that we are to think about is the +mineral matter. The ashes of a burnt plant furnish a common example of +this mineral matter. The animal uses this material of the plant to make +bone, teeth, and tissue. + +The last thing that the plant furnishes the animal is water--just common +water. Young plants contain comparatively large quantities of water. +This is one reason why they are soft, juicy, and palatable. But, since +animals get their water chiefly in another way, the water in feed stuffs +is not important. + + +WHAT THESE COMPOUNDS DO IN THE BODY + + _Protein_ + + 1. Forms flesh, bone, blood, internal organs, hair, and milk. + 2. May be used to make fat. + 3. May be used for heat. + 4. May be used to produce energy. + + _Carbohydrates_ + + 1. Furnish body heat. + 2. Furnish energy. + 3. Make fat. + + _Fat_ + + 1. Furnishes body heat. + 2. Furnishes energy. + 3. Furnishes body fat. + + _Mineral Matter_ + + Furnishes mineral matter for the bones in the body. + + _Water_ + + Supplies water in the body. + + + + +CHAPTER XI + +FARM DAIRYING + + +SECTION LX. THE DAIRY COW + +Success in dairy farming depends largely upon the proper feeding of +stock. There are two questions that the dairy farmer should always ask +himself: Am I feeding as cheaply as I can? and, Am I feeding the best +rations for milk and butter production? Of course cows can be kept alive +and in fairly good milk flow on many different kinds of food, but in +feeding, as in everything else, there is an ideal to be sought. + +[Illustration: FIG. 268. MILKING-TIME] + +What, then, is an ideal ration for a dairy cow? Before trying to answer +this question the word _ration_ needs to be explained. By ration is +meant a sufficient quantity of food to support properly an animal for +one day. If the animal is to have a proper ration, we must bear in mind +what the animal needs in order to be best nourished. To get material for +muscle, for blood, for milk, and for some other things, the animal +needs, in the first place, food that contains protein. To keep warm and +fat, the animal must, in the second place, have food containing +carbohydrates and fats. These foods must be mixed in right proportions. + +[Illustration: FIG. 269. A DAIRY] + +With these facts in mind we are prepared for an answer to the question, +What is an ideal ration? + +First, it is a ration that, without waste, furnishes both in weight and +bulk of dry matter a sufficient amount of digestible, nutritious food. + +Second, it is a ration that is comparatively cheap. + +Third, it is a ration in which the milk-forming food (protein) is +rightly proportioned to the heat-making and fat-making food +(carbohydrates and fat). Any ration in which this proportion is +neglected is badly balanced. + +Now test one or two commonly used rations by these rules. Would a ration +of cotton-seed meal and cotton-seed hulls be a model ration? No. Such a +ration, since the seeds are grown at home, would be cheap enough. +However, it is badly balanced, for it is too rich in protein; hence it +is a wasteful ration. Would a ration of corn meal and corn stover be a +desirable ration? This, too, since the corn is home-grown, would be +cheap for the farmer; but, like the other, it is badly balanced, for it +contains too much carbohydrate food and is therefore a wasteful ration. + +A badly balanced ration does harm in two ways: first, the milk flow of +the cow is lessened by such a ration; second, the cow does not +profitably use the food that she eats. + +The following table gives an excellent dairy ration for the farmer who +has a silo. If he does not have a silo, some other food can be used in +place of the ensilage. The table also shows what each food contains. As +you grow older, it will pay you to study such tables most carefully. + + + =============================================================== + | DIGESTIBLE MATTER + |---------------------------------- + FEED STUFFS | Dry |Protein|Carbohydrates| Fat + |matter| | | + --------------------------------------------------------------- + Cowpea hay = 15 pounds[1] | 13.50| 1.62 | 5.79 | .16 + Corn stover = 10 pounds | 5.95| .17 | 3.24 | .07 + Corn ensilage = 30 pounds | 6.27| .27 | 3.39 | .21 + Cotton-seed meal = 2 pounds | 1.83| .74 | .33 | .24 + --------------------------------------------------------------- + Total = 57 pounds | 27.55| 2.80 | 12.75 | .68 + =============================================================== + +[Footnote 1: Alfalfa or clover hay may take the place of cowpea hay.] + +=Care of the Cow.= As the cow is one of the best money-makers on the +farm, she should, for this reason, if for no other, be comfortably +housed, well fed and watered, and most kindly treated. In your thoughts +for her well-being, bear the following directions in mind: + +1. If you are not following a balanced ration, feed each day several +different kinds of food. In this way you will be least likely to waste +food. + +2. Feed at regular hours. Cows, like people, thrive best when their +lives are orderly. + +3. Milk at regular hours. + +4. Brush the udder carefully with a moist cloth before you begin to +milk. Cleanliness in handling makes the milk keep longer. + +5. Always milk in buckets or cups that have been scalded since the last +using. The hot water kills the bacteria that collect in the dents or +cracks of the utensil. + +6. Never let the milk pail remain in the stable. Milk rapidly absorbs +impurities. These spoil the flavor and cause the milk to sour. + +7. Never scold or strike the cow. She is a nervous animal, and rough +usage checks the milk flow. + +[Illustration] + +[Illustration: THREE GENERATIONS OF HIGH-BRED COWS] + + +SECTION LXI. MILK, CREAM, CHURNING, AND BUTTER + +=Milk.= Milk is, as you know, nature's first food for mammals. This is +because milk is a model food--it contains water to slake thirst, ash to +make bone, protein to make flesh and muscle, and fat and sugar to keep +the body warm and to furnish energy. + +=The Different Kinds of Milk.= Whole, or unskimmed, milk, skimmed milk, +and buttermilk are too familiar to need description. When a cow is just +fresh, her milk is called _colostrum_. Colostrum is rich in the very +food that the baby calf needs. After the calf is a few days old, +colostrum changes to what is commonly known as milk. + +The following table shows the composition of each of the different forms +of milk: + + ======================================================= + | DIGESTIBLE MATTER IN 100 POUNDS + |---------------------------------- + COMPOSITION OF MILK | Dry |Protein|Carbohydrates| Fat + |matter| | | + ------------------------------------------------------- + Colostrum | 25.4 | 17.6 | 2.7 | 3.6 + Milk (unskimmed) | 12.8 | 3.6 | 4.9 | 3.7 + Skimmed milk | 9.4 | 2.9 | 5.2 | 1.3 + Buttermilk | 9.9 | 3.9 | 4.0 | 1.1 + ======================================================= + +A noticeable fact in this table is that skimmed milk differs from +unskimmed mainly in the withdrawal of the fat. Hence, if calves are fed +on skimmed milk, they should have in addition some food like corn meal +to take the place of the fat withdrawn. A calf cannot thrive on skimmed +milk alone. The amount of nourishing fat that a calf gets out of enough +milk to make a pound of butter can be bought, in the form of linseed or +corn meal, for a very small amount, while the butter-fat costs, for +table use, a much larger sum. Of course, then, it is not economical to +allow calves to use unskimmed milk. Some people undervalue skimmed milk; +with the addition of some fatty food it makes an excellent ration for +calves, pigs, and fowls. + +Along with its dry matter, its protein, its carbohydrates, and its fats, +milk and its products possess another most important property. This +property is hard to describe, for its elements and its powers are not +yet fully understood. We do, however, know certainly this much: milk and +the foods made from it have power to promote health and favor growth in +a more marked degree than any other foods. It is generally agreed that +this is due to the health-promoting and health-preserving substances +which are called vitamines. Men of science are working with much care to +try to add to our knowledge of these vitamines, which have so marvelous +an influence on the health of all animals. Unless food, no matter how +good otherwise, contains these vitamines, it does not nourish the body +nor preserve bodily health as it should. A complete lack of vitamines in +our food would cause death. Since, then, milk and its products--butter, +cheese, curds--are rich in vitamines, these health-giving and +health-preserving foods should form a regular part of each person's +diet. + +[Illustration: FIG. 270. AIRING THE CANS] + +=Cream.= Cream is simply a mixture of butter-fat and milk. The +butter-fat floats in the milk in little globe-shaped bodies, or +globules. Since these globules are lighter than milk, they rise to the +surface. Skimming the milk is a mere gathering together of these +butter-fat globules. As most of the butter-fat is contained in the +cream, pains should be taken to get all the cream from the milk at +skimming time. + +After the cream has been collected, it must be allowed to "ripen" or to +"sour" in order that it may be more easily churned. Churning is only a +second step to collect in a compact shape the fat globules. It often +happens that at churning-time the cream is too warm for successful +separation of the globules. Whenever this is the case the cream must be +cooled. + +[Illustration: FIG. 271. A HAND SEPARATOR] + +=The Churn.= Revolving churns without inside fixtures are best. Hence, +in buying, select a barrel or a square box churn. This kind of churn +"brings the butter" by the falling of the cream from side to side as the +churn is revolved. Never fill the churn more than one-third or one-half +full of cream. A small churn is always to be avoided. + +=Churning.= The proper temperature for churning ranges from 58° to 62° +Fahrenheit. Test the cream when it is put into the churn. If it be too +cold, add warm water until the proper temperature is reached; if too +warm, add cold water or ice until the temperature is brought down to +62°. Do not churn too long, for this spoils butter. As soon as the +granules of butter are somewhat smaller than grains of wheat, stop the +churn. Then draw off the buttermilk and at a temperature as low as 50° +wash the butter in the churn. This washing with cold water so hardens +the granules that they do not mass too solidly and thus destroy the +grain. + +=Butter.= The butter so churned is now ready to be salted. Use good fine +dairy salt. Coarse barrel salt is not fit for butter. The salt can be +added while the butter is still in the churn or after it is put upon the +butter-worker. Never work by hand. The object of working is to get the +salt evenly distributed and to drive out some of the brine. It is +usually best to work butter twice. The two workings bring about a more +even mixture of the salt with the butter and drive off more water. But +one cannot be too particular not to overwork butter. Delicate coloring, +attractive stamping with the dairy owner's special stamp, and proper +covering with paper cost little and of course add to the ready and +profitable sale of butter. + +[Illustration: FIG. 272. A POWER CHURN] + + +DAIRY RULES + +_Stable and Cows_ + +1. Whitewash the stable once or twice each year; use land plaster, muck, +or loam daily in the manure-gutters. + +2. On their way to pasture or milking-place, do not allow the cows to be +driven at a faster gait than a comfortable walk. + +3. Give abundance of pure water. + +4. Do not change feed suddenly. + +5. Keep salt always within reach of each cow. + +_Milking_ + +1. Milk with dry hands. + +2. Never allow the milk to touch the milker's hands. + +3. Require the milker to be clean in person and dress. + +4. Milk quietly, quickly, thoroughly. Never leave a drop of milk in the +cow's udder. + +5. Do not allow cats, dogs, or other animals around at milking-time. + +_Utensils_ + +1. Use only tin or metal cans and pails. + +2. See that all utensils are thoroughly clean and free from rust. + +3. Require all cans and pails to be scalded immediately after they are +used. + +4. After milking, keep the utensils inverted in pure air, and sun them, +if possible, until they are wanted for use. + +5. Always sterilize the churn with steam or boiling water before and +after churning. This prevents any odors or bad flavors from affecting +the butter. All cans, pails, and bottles should also be sterilized +daily. + +[Illustration] + + +SECTION LXII. HOW MILK SOURS + +[Illustration: FIG. 273. MICROSCOPIC APPEARANCE OF PURE AND IMPURE MILK +At the left, pure milk; at the right, milk after standing in a warm room +for a few hours in a dirty dish, showing, besides the fat-globules, many +forms of bacteria] + +On another page you have been told how the yeast plant grows in cider +and causes it to sour, and how bacteria sometimes cause disease in +animals and plants. Now you must learn what these same living forms have +to do with the souring of milk, and maybe you will not forget how you +can prevent your milk from souring. In the first place, milk sours +because bacteria from the air fall into the milk, begin to grow, and +very shortly change the sugar of the milk to an acid. When this acid +becomes abundant, the milk begins to curdle. As you know, the bacteria +are in air, in water, and in barn dust; they stick on bits of hay and +stick to the cow. They are most plentiful, however, in milk that has +soured; hence, if we pour a little sour milk into a pail of fresh milk, +the fresh milk will sour very quickly, because we have, so to speak, +"seeded" or "planted" the fresh milk with the souring germs. No one, of +course, ever does this purposely in the dairy, yet people sometimes do +what amounts to the same thing--that is, put fresh milk into poorly +cleaned pails or pans, the cracks and corners of which are cozy homes +for millions of germs left from the last sour milk contained in the +vessel. It follows, then, that all utensils used in the dairy should be +thoroughly scalded so as to kill all germs present, and particular care +should be taken to clean the cracks and crevices, for in them the germs +lurk. + +In addition to this thorough cleansing with hot water, we should be +careful never to stir up the dust of the barn just before milking. Such +dusty work as pitching hay or stover or arranging bedding should be done +either after or long before milking-time, for more germs fall into the +milk if the air be full of dust. + +To further avoid germs the milker should wear clean overalls, should +have clean hands, and, above all, should never wet his hands with milk. +This last habit, in addition to being filthy, lessens the keeping power +of the milk. The milker should also moisten the parts of the cow which +are nearest him, so that dust from the cow's sides may not fall into the +milker's pail. For greater cleanliness and safety many milkmen curry +their cows. + +The first few streams from each teat should be thrown away, because the +teat at its mouth is filled with milk which, having been exposed to the +air, is full of germs, and will do much toward souring the other milk in +the pail. Barely a gill will be lost by throwing the first drawings +away, and this of the poorest milk too. The increase in the keeping +quality of the milk will much more than repay the small loss. If these +precautions are taken, the milk will keep several hours or even several +days longer than milk carelessly handled. By taking these steps to +prevent germs from falling into the milk, a can of milk was once kept +sweet for thirty-one days. + +The work of the germ in the dairy is not, however, confined to souring +the milk. Certain kinds of germs give to the different sorts of cheeses +their marked flavors and to butter its flavor. If the right germ is +present, cheese or butter gets a proper flavor. Sometimes undesirable +germs gain entrance and give flavors that we do not like. Such germs +produce cheese or butter diseases. "Bitter butter" is one of these +diseases. To keep out all unpleasant meddlers, thoroughly cleanse and +scald every utensil. + + EXERCISE + + What causes milk to sour? Why do unclean utensils affect the milk? + How should milk be cared for to prevent its souring? Prepare two + samples, one carefully, the other carelessly. Place them side by + side. Which keeps longer? Why? + + +SECTION LXIII. THE BABCOCK MILK-TESTER + +It is not sufficient for a farmer or a dairyman to know how much milk +each of his cows yields. He should also know how rich the milk is in +butter-fat. Wide-awake makers of butter and cheese now buy milk, not by +the pound or by the gallon, but by the amount of butter-fat contained in +each pound or gallon of milk. A gallon of milk containing four and a +half per cent of fat will consequently be worth more than a gallon +containing only three per cent of fat. So it may happen that a cow +giving only two gallons of milk may pay a butter-maker more than a cow +giving three gallons of milk. Of course it is easy to weigh or measure +the quantity of milk given by a cow, and most milkers keep this record; +but until recent years there was no way to find out the amount of fat in +a cow's milk except by a slow and costly chemical test. Dairymen could +only guess at the richness of milk. + +In 1890 Dr. S. M. Babcock of the Wisconsin Experiment Station invented a +wonderful little machine that quickly and cheaply measures the fat in +milk. Few machines are more useful. So desirous was Dr. Babcock of +helping the farmers that he would not add to the cost of his machine by +taking out a patent on his invention. His only reward has been the fame +won by the invention of the machine, which bears his name. This most +useful tester is now made in various sizes so that every handler of milk +may buy one suited to his needs and do his own testing at very little +cost. + +The operation of the machine is very simple. Suppose that the members of +the class studying this book have been asked to take a Babcock machine +and test the milk of a small herd of cows. They can readily do so by +following these directions: + +While the milk is still warm from the first cow to be tested, mix it +thoroughly by pouring it at least four times from one vessel to another. +A few ounces of this mixed milk is then taken for a sample, and +carefully marked with the name of the cow. A number is also put on the +sample, and both the cow's name and the number entered in a notebook. A +small glass instrument, called a pipette, comes with each machine. Put +one end of the pipette into the milk sample and the other end into the +mouth. Suck milk into the pipette until the milk comes up to the mark on +the side of the pipette. As soon as the mark is reached, withdraw the +pipette from the mouth and quickly press the forefinger on the mouth +end. The pressure of the finger will keep the milk from running out. +Then put the lower end of the pipette into one of the small long-necked +bottles of the machine, and, lifting the finger, allow the milk to flow +gently into the bottle. Expel all the milk by blowing through the +pipette. + +The next step is to add a strong, biting acid known as sulphuric acid to +the test-bottle into which you have just put the milk. A glass marked to +show just how much acid to use also comes with the machine. Fill this +glass measure to the mark. Then pour the acid carefully into the +test-bottle. Be sure not to drop any of the acid on your hands or your +clothes. As the acid is heavier than the milk, it will sink to the +bottom of the bottle. With a gentle whirling motion, shake the bottle +until the two fluids are thoroughly mixed. The mixture will turn a dark +brown and become very warm. + +Now fill the other bottles in the same way with samples drawn from +different cows. Treat all the samples precisely as you did the first. Do +not forget to put on each sample the name of the cow giving the milk and +on each test-bottle a number corresponding to the name of the cow. + +You are now ready to put the test-bottles in the sockets of the machine. +Arrange the bottles in the sockets so that the whirling frame of the +machine will be balanced. Fit the cover on the machine and turn the +handle slowly. Gradually gain in speed until the machine is whirled +rapidly. Continue the turning for about seven minutes at the speed +stated in the book of directions. + +After this first turning is finished, pour enough hot water into each +test-bottle to cause the fat to rise to the neck of the bottle. Re-cover +the machine and turn for one minute. Again add hot water to each bottle +until all the fat rises into the neck of the bottle and again turn one +minute. + +There remains now only the reading of the record. On the neck of each +bottle there are marks to measure the amount of fat. If the fat inside +the tube reaches only from the lowest mark to the second mark, then +there is only one per cent of fat in this cow's milk. This means that +the owner of the cow gets only one pound of butter-fat from each +hundred pounds of her milk. Such a cow would not be at all profitable to +a butter-seller. If the fat in another test-bottle reaches from the +lowest mark to the fourth mark, then you put in your record-book that +this cow's milk contains four per cent of butter-fat. This record shows +that the second cow's milk yields four pounds of fat to every hundred +pounds of milk. This cow is three times more valuable to a butter-maker +than the first cow. In the same way add one more per cent for each +higher mark reached by the fat. Four and one-half per cent is a good +record for a cow to make. Some cows yield as high as five or six per +cent but they do not generally keep up this record all the year. + +[Illustration: FIG. 274. BABCOCK TESTER AND HOW TO USE IT +The tester, acid, acid measure, test-bottle, and thermometer at bottom; +filling the pipette on right; adding the acid and measuring the fat at +top] + +The Babcock tester shows only the amount of pure butter-fat in the milk. +It does not tell the exact amount of finished butter which is made from +100 pounds of milk. This is because butter contains a few other things +in addition to pure butter-fat. Finished and salted butter weighs on an +average about one sixth more than the fat shown by the tester. Hence to +get the exact amount of butter in every 100 pounds of milk, you will +have to add one sixth to the record shown by the tester. Suppose, for +example, you took one sample from 600 pounds of milk and that your test +showed 4 per cent of fat in every 100 pounds of milk. Then, as you had +600 pounds of milk, you would have 24 pounds of butter-fat. This fat, +after it has been salted and after it has absorbed moisture as butter +does, will gain one sixth in weight. As one sixth of 24 is 4, this new 4 +pounds must be added to the weight of the butter-fat. Hence the 600 +pounds of milk would produce about 28 pounds of butter. + + EXERCISE + + 1. Find the number of pounds of butter in 1200 pounds of milk that + tests 3 per cent of butter-fat. + + 2. A cow yields 4800 pounds of milk in a year. Her milk tests 4 per + cent of butter-fat. Find the total amount of butter-fat she yields. + Find also the total amount of butter. + + 3. The milk of two cows was tested: one yielded in a year 6000 + pounds of milk that tested 3 per cent of fat; the other yielded + 5000 pounds that tested 4 per cent. Which cow yielded the more + butter-fat? What was the money value of the butter produced by each + if butter-fat is worth twenty-five cents a pound? + + + + +CHAPTER XII + +MISCELLANEOUS + + +SECTION LXIV. GROWING FEED STUFFS ON THE FARM + +Economy in raising live stock demands the production of all "roughness" +or roughage materials on the farm. By roughness, or roughage, of course +you understand that bulky food, like hay, grass, clover, stover, etc., +is meant. It is possible to purchase all roughage materials and yet make +a financial success of growing farm animals, but this certainly is not +the surest way to succeed. Every farm should raise all its feed stuffs. +In deciding what forage and grain crops to grow we should decide: + + 1. The crops best suited to our soil and climate. + 2. The crops best suited to our line of business. + 3. The crops that will give us the most protein. + 4. The crops that produce the most. + 5. The crops that will keep our soil in the best condition. + +1. _The crops best suited to our soil and climate._ Farm crops, as every +child of the farm knows, are not equally adapted to all soils and +climates. Cotton cannot be produced where the climate is cool and the +seasons short. Timothy and blue grass are most productive on cool, +limestone soils. Cowpeas demand warm, dry soils. But in spite of +climatic limitations, Nature has been generous in the wide variety of +forage she has given us. + +Our aim should be to make the best use of what we have, to improve by +selection and care those kinds best adapted to our soil and climate, and +to secure, by better methods of growing and curing, the greatest yields +at the least possible cost. + +2. _The crops best suited to our line of business._ A farmer necessarily +becomes more or less of a specialist; he gathers those kinds of live +stock about him which he likes best and which he finds the most +profitable. He should, on his farm, select for his main crops those that +he can grow with the greatest pleasure and with the greatest profit. + +[Illustration: FIG. 275. FILLING THE BARN WITH ROUGHAGE FROM THE FARM] + +The successful railroad manager determines by practical experience what +distances his engines and crews ought to run in a day, what coal is most +economical for his engines, what schedules best suit the needs of his +road, what trains pay him best. These and a thousand and one other +matters are settled by the special needs of his road. + +Ought the man who wants to make his farm pay be less prudent and less +far-sighted? Should not his past failures and his past triumphs decide +his future? If he be a dairy farmer, ought he not by practical tests to +settle for himself not only what crops are most at home on his land but +also what crops in his circumstances yield him the largest returns in +milk and butter? If swine-raising be his business, how long ought he to +guess what crop on his land yields him the greatest amount of hog food? +Should a colt be fed on one kind of forage when the land that produced +that forage would produce twice as much equally good forage of another +kind? All these questions the prudent farmer should answer promptly and +in the light of wise experiments. + +3. _The crops that will give us the most protein._ It is the farmer's +business to grow all the grass and forage that his farm animals need. He +ought never to be obliged to purchase a bale of forage. Moreover, he +should grow mainly those crops that are rich in protein materials, for +example, cowpeas, alfalfa, and clover. If such crops are produced on the +farm, there will be little need of buying so much cotton-seed meal, +corn, and bran for feeding purposes. + +4. _The crops that produce the most._ We often call a crop a crop +without considering how much it yields. This is a mistake. We ought to +grow, when we have choice of two crops, the one that is the best and the +most productive on the farm. Average corn, for instance, yields on an +acre at least twice the quantity of feeding-material that timothy does. + +5. _The crops that will keep our soil in the best condition._ A good +farmer should always be thinking of how to improve his soil. He wants +his land to support him and to maintain his children after he is dead. + +Since cowpeas, clover, and alfalfa add atmospheric nitrogen to the soil +and at the same time are the best feeding-materials, it follows that +these crops should hold an important place in every system of +crop-rotation. By proper rotating, by proper terracing, and by proper +drainage, land may be made to retain its fertility for generations. + + EXERCISE + + 1. Why are cowpeas, clover, and alfalfa so important to the farmer? + + 2. What is meant by the protein of a food? + + 3. Why is it better to feed the farm crops to animals on the farm + rather than to sell these crops? + + +SECTION LXV. FARM TOOLS AND MACHINES + +The drudgery of farm life is being lessened from year to year by the +invention or improvement of farm tools and machines. Perhaps some of you +know how tiresome was the old up-and-down churn dasher that has now +generally given place to the "quick-coming" churns. The toothed, +horse-drawn cultivator has nearly displaced "the man with the hoe," +while the scythe, slow and back-breaking, is everywhere getting out of +the way of the mowing-machine and the horserake. The old heavy, +sweat-drawing grain-cradle is slinking into the backwoods, and in its +place we have the horse-drawn or steam-drawn harvester that cuts and +binds the grain, and even threshes and measures it at one operation. +Instead of the plowman's wearily making one furrow at a time, the +gang-plows of the plains cut many furrows at one time, and instead of +walking the plowman rides. The shredder and husker turns the hitherto +useless cornstalk into food, and at the same time husks, or shucks, the +corn. + +The farmer of the future must know three things well: first, what +machines he can profitably use; second, how to manage these machines; +third, how to care for these machines. + +[Illustration: FIG. 276. PROPERLY PROTECTED TOOLS AND MACHINES] + +[Illustration: FIG. 277. UNPROTECTED TOOLS AND MACHINES] + +[Illustration: FIG. 278. THE HARVESTER AT WORK] + +[Illustration: FIG. 279. IN NEED OF IMPROVEMENT] + +The machinery that makes farming so much more economical and that makes +the farmer's life so much easier and more comfortable is too complicated +to be put into the hands of bunglers who will soon destroy it, and it is +too costly to be left in the fields or under trees to rust and rot. + +If it is not convenient for every farmer to have a separate tool-house, +he should at least set apart a room in his barn, or a shed for storing +his tools and machines. As soon as a plow, harrow, cultivator--indeed +any tool or machine--has finished its share of work for the season, it +should receive whatever attention it needs to prevent rusting, and +should be carefully housed. + +Such care, which is neither costly nor burdensome, will add many years +to the life of a machine. + + +SECTION LXVI. LIMING THE LAND + +Occasionally, when a cook puts too much vinegar in a salad, the dish +becomes so sour that it is unfit to eat. The vinegar which the cook uses +belongs to a large group of compounds known as acids. The acids are +common in nature. They have the power not only of making salads sour but +also of making land sour. Frequently land becomes so sour from acids +forming in it that it will not bear its usual crops. The acids must then +be removed or the land will become useless. + +The land may be soured in several ways. Whenever a large amount of +vegetable matter decays in land, acids are formed, and at times sourness +of the soil results. Often soils sour because they are not well drained +or because, from lack of proper tillage, air cannot make its way into +the soil. Sometimes all these causes may combine to produce sourness. +Since most crops cannot thrive on very sour soil, the farmer must find +some method of making his land sweet again. + +So far as we now know, liming the land is the cheapest and surest way of +overcoming the sourness. In addition to sweetening the soil by +overcoming the acids, lime aids the land in other ways: it quickens the +growth of helpful bacteria; it loosens stiff, heavy clay soils and +thereby fits them for easier tillage; it indirectly sets free the potash +and phosphoric acid so much needed by plants; and it increases the +capillarity of soils. + +However, too much must not be expected of lime. Often a farmer's yield +is so increased after he has scattered lime over his fields that he +thinks that lime alone will keep his land fertile. This belief explains +the saying, "Lime enriches the father but beggars the son." The +continued use of lime without other fertilization will indeed leave poor +land for the son. Lime is just as necessary to plant growth as the +potash and nitrogen and phosphoric acid about which we hear so much, but +it cannot take the place of these plant foods. Its duty is to aid, not +to displace them. + +We can tell by the taste when salads are too sour; it is more difficult +to find out whether land is sour. There are, however, some methods that +will help to determine the sourness of the soil. + +In the first place, if land is unusually sour, you can determine this +fact by a simple test. Buy a pennyworth of blue litmus paper from a drug +store. Mix some of the suspected soil with a little water and bury the +litmus paper in the mixture. If the paper turns red the soil is sour. + +In the second place, the leguminous crops are fond of lime. Clover and +vetch remove so much lime from the soil that they are often called lime +plants. If clover and vetch refuse to grow on land on which they +formerly flourished, it is generally, though not always, a sign that the +land needs lime. + +In the third place, when water grasses and certain weeds spring up on +land, that land is usually acid, and lime will be helpful. Moreover, +fields adjoining land on which cranberries, raspberries, blackberries, +or gallberries are growing wild, may always be suspected of more or less +sourness. + +Four forms of lime are used on land. These, each called by different +names, are as follows: + +First, quicklime, which is also called burnt lime, caustic lime, +builders' lime, rock lime, and unslaked lime. + +Second, air-slaked lime, which is also known as carbonate of lime, +agricultural lime, marl, and limestone. + +Third, water-slaked, or hydrated, lime. + +Fourth, land plaster, or gypsum. This form of lime is known to the +chemists as sulphate of lime. Do not forget that this last form is never +to be used on sour lands. We shall therefore not consider it further. + +Air-slaked lime is simply quicklime which has taken from the air a gas +called carbon dioxide. This is the same gas that you breathe out from +your lungs. + +Water-slaked lime is quicklime to which water has been added. In other +words, both of these are merely weakened forms of quicklime. One hundred +pounds of quicklime is equal in richness to 132 pounds of water-slaked +lime and to 178 pounds of air-slaked lime. These figures should be +remembered by a farmer when he is buying lime. If he can buy a fair +grade of quicklime delivered at his railway station for $5.00 a ton, he +cannot afford to pay more than $3.75 a ton for water-slaked lime, nor +more than $2.75 for air-slaked lime of equal grade. Quicklime should +always be slaked before it is applied to the soil. + +As a rule lime should be spread broadcast and then harrowed or disked +thoroughly into the soil. This is best done after the ground has been +plowed. For pastures or meadows air-slaked lime is used as a +top-dressing. When air-slaked lime is used it may be spread broadcast in +the spring; the other forms should be applied in the fall or in the +early winter. + + +SECTION LXVII. BIRDS + +What do birds do in the world? is an important question for us to think +about. First, we must gain by observation and by personal acquaintance +with the living birds a knowledge of their work and their way of doing +it. In getting this knowledge, let us also consider what we can do for +our birds to render their work as complete and effective as possible. + +Think of what the birds are doing on every farm, in every garden, and +about every home in the land. Think of the millions of beautiful wings, +of the graceful and attractive figures, of the cunning nests, and of the +singing throats! Do you think that the whole service of the birds is to +be beautiful, to sing charmingly, and to rear their little ones? By no +means is this their chief service to man. Aside from these services the +greatest work of birds is to destroy insects. It is one of the wise +provisions of nature that many of the most brilliantly winged and most +enchanting songsters are our most practical friends. + +Not all birds feed on insects and animals; but even those that eat but a +small amount of insect food may still destroy insects that would have +damaged fruit and crops much more than the birds themselves do. + +As to their food, birds are divided into three general classes. First, +those that live wholly or almost wholly on insects. These are called +insectivorous birds. Chief among these are the warblers, cuckoos, +swallows, martins, flycatchers, nighthawks, whippoorwills, swifts, and +humming-birds. We cannot have too many of these birds. They should be +encouraged and protected. They should be supplied with shelter and +water. + +Birds of the second class feed by preference on fruits, nuts, and grain. +The bluebird, robin, wood thrush, mocking-bird, catbird, chickadee, +cedar-bird, meadow lark, oriole, jay, crow, and woodpecker belong to +this group. These birds never fail to perform a service for us by +devouring many weed seeds. + +[Illustration: FIG. 280. A KINGBIRD] + +The third class is known as the hard-billed birds. It includes those +birds which live principally on seeds and grain--the canary, goldfinch, +sparrow, and some others. + +Birds that come early, like the bluebird, robin, and redwing, are of +special service in destroying insects before the insects lay their eggs +for the season. + +The robins on the lawn search out the caterpillars and cutworms. The +chipping sparrow and the wren in the shrubbery look out for all kinds of +insects. They watch over the orchard and feed freely on the enemies of +the apple and other fruit trees. The trunks of these trees are often +attacked by borers, which gnaw holes in the bark and wood, and often +cause the death of the trees. The woodpeckers hunt for these appetizing +borers and by means of their barbed tongues bring them from their +hiding-places. On the outside of the bark of the trunk and branches the +bark lice work. These are devoured by the nuthatches, creepers, and +chickadees. + +During the winter the bark is the hiding-place for hibernating insects, +which, like plant lice, feed in summer on the leaves. Throughout the +winter a single chickadee will destroy great numbers of the eggs of the +cankerworm moth and of the plant louse. The blackbirds, meadow larks, +crows, quail, and sparrows are the great protectors of the meadow and +field crops. These birds feed on the army worms and cutworms that do so +much injury to the young shoots; they also destroy the chinch bug and +the grasshopper, both of which feed on cultivated plants. + +[Illustration: FIG. 281. A WARBLER] + +A count of all the different kinds of animals shows that insects make up +nine tenths of them. Hence it is easy to see that if something did not +check their increase they would soon almost overrun the earth. Our +forests and orchards furnish homes and breeding-places for most of these +insects. Suppose the injurious insects were allowed to multiply +unchecked in the forests, their numbers would so increase that they +would invade our fields and create as much terror among the farmers as +they did in Pharaoh's Egypt. The birds are the only direct friends man +has to destroy these harmful insects. What benefactors, then, these +little feathered neighbors are! + +It has been estimated that a bird will devour thirty insects daily. Even +in a widely extended forest region a very few birds to the acre, if they +kept up this rate, would daily destroy many bushels of insects that +would play havoc with the neighboring orchards and fields. + +Do not imagine, however, that to destroy insects is the only use of +birds. The day is far more delightful when the birds sing, and when we +see them flit in and out, giving us a glimpse now and then of their +pretty coats and quaint ways. By giving them a home we can surround +ourselves with many birds, sweet of song and brilliant of plumage. + +[Illustration: FIG. 282. THE HAIRY WOODPECKER] + +If the birds felt that man were a friend and not a foe, they would often +turn to him for protection. During times of severe storm, extreme +drought, or scarcity of food, if the birds were sufficiently tamed to +come to man as their friend, as they do in rare cases now, a little food +and shelter might tide them over the hard time and their service +afterwards would repay the outlay a thousandfold. If the boys in your +families would build bird-houses about the house and barn and in shade +trees, they might save yearly a great number of birds. In building these +places of shelter and comfort, due care must be taken to keep them +clear of English sparrows and out of the reach of cats and bird-dogs. + +Whatever we do to attract the birds to make homes on the premises must +be done at the right time and in the right way. Think out carefully what +materials to provide for them. Bits of string, linen, cotton, yarn, tow +and other waste material, all help to induce a pair to build in the +garden. + +[Illustration: FIG. 283. PROTECTING OUR FRIENDS] + +It is an interesting study--the preparation of homes for the birds. +Trees may be pruned to make inviting crotches. A tangled, overgrown +corner in the garden will invite some birds to nest. + +Wrens, bluebirds, chickadees, martins, and some other varieties are all +glad to set up housekeeping in man-made houses. The proper size for a +bird-room is easily remembered. Give each room six square inches of +floor space and make it eight inches high. Old, weathered boards should +be used; or, if paint is employed, a dull color to resemble an old +tree-trunk will be most inviting. A single opening near the top should +be made two inches in diameter for the larger birds; but if the house is +to be headquarters for the wren, a one-inch opening is quite large +enough, and the small door serves all the better to keep out English +sparrows. + +The barn attic should be turned over to the swallows. Small holes may be +cut high up in the gables and left open during the time that the +swallows remain with us. They will more than pay for shelter by the good +work they do in ridding the barn of flies, gnats, and mosquitoes. + + +SECTION LXVIII. FARMING ON DRY LANDS + +Almost in the center of the western half of our continent there is a +vast area in which very little rain falls. This section includes nearly +three hundred million acres of land. It stretches from Canada on the +north into Texas on the south, and from the Missouri River (including +the Dakotas and western Minnesota) on the east to the Rocky Mountains on +the west. In this great area farming has to be done with little water. +This sort of farming is therefore called "dry-farming." + +The soil in this section is as a rule very fertile. Therefore the +difference between farming in this dry belt and farming in most of the +other sections of our country is a difference mainly due to a lack of +moisture. + +As water is so scarce in this region two things are of the utmost +importance: first, to save all the rain as it falls; second, to save all +the water after it has fallen. To save the falling rain it is necessary +for the ground to be in such a condition that none of the much-needed +rain may run off. Every drop should go into the soil. Hence the farmer +should never allow his top soil to harden into a crust. Such a crust +will keep the rain from sinking into the thirsty soil. Moreover the soil +should be deeply plowed. The deeper the soil the more water it can hold. +The land should also be kept as porous as possible, for water enters a +porous soil freely. The addition of humus in the form of vegetable +manures will keep the soil in the porous condition needed. Second, after +the water has entered the soil it is important to hold it there so that +it may supply the growing crops. If the land is allowed to remain +untilled after a rain or during a hot spell, the water in it will +evaporate too rapidly and thus the soil, like a well, will go dry too +soon. To prevent this the top soil should be stirred frequently with a +disk or smoothing harrow. This stirring will form a mulch of dry soil on +the surface, and this will hold the water. Other forms of mulch have +been suggested, but the soil mulch is the only practical one. It must be +borne in mind that this surface cultivation must be regularly kept up if +the moisture is to be retained. + +[Illustration: FIG. 284. THE DISK HARROW] + +Some experiments in wheat-growing have shown how readily water might be +saved if plowing were done at the right time. Wheat sowed on land that +was plowed as soon as the summer crops were taken off yielded a very +much larger return than wheat sowed on land that remained untilled for +some time after the summer crops were gathered. This difference in yield +on lands of the same fertility was due to the fact that the early +plowing enabled the land to take up a sufficient quantity of moisture. + +[Illustration: FIG. 285. RED KAFIR CORN IN SHOCK] + +In addition to a vigilant catching and saving of water, the farmer in +these dry climates must give his land the same careful attention that +lands in other regions need. The seed-bed should be most carefully +prepared. It should be deep, porous, and excellent in tilth. During the +growing season all crops should be frequently cultivated. The harrow, +the cultivator, and the plow should be kept busy. The soil should be +kept abundantly supplied with humus. + +Some crops need a little different management in dry-farming. Corn, for +example, does best when it is listed; that is, planted so that it will +come up three or four inches beneath the surface. If planted in this +way, it roots better, stands up better, and requires less work. + +Just as breeders study what animals are best for their climates, so +farmers in the dry belt should study what crops are best suited to their +lands. Some crops, like the sorghums and Kafir corn, are peculiarly at +home in scantily watered lands. Others do not thrive. Experience is the +only sure guide to the proper selection. + +To sum up, then, farmers can grow good crops in these lands only when +four things are done: first, the land must be thoroughly tilled so that +water can freely enter the soil; second, the land must be frequently +cultivated so that the water will be kept in the soil; third, the crops +must be properly rotated so as to use to best advantage the food and +water supply; fourth, humus must be freely supplied so as to keep the +soil in the best possible condition. + + +SECTION LXIX. IRRIGATION + +Irrigation is the name given to the plan of supplying water in large +quantities to growing crops. Since the dawn of history this practice has +been more or less followed in Asia, in Africa, and in Europe. The +Spanish settlers in the southwestern part of America were probably the +first to introduce this custom into our country. In New Mexico there is +an irrigating trench that has been in constant use for three hundred +years. + +[Illustration: FIG. 286. PUMPING WATER FOR IRRIGATION] + +The most common source of water for irrigating purposes is a river or a +smaller stream. Artesian wells are used in some parts of the country. +Windmills are sometimes used when only a small supply of water is +needed. Engines, hydraulic rams, and water-wheels are also employed. The +water-wheel is one of the oldest and one of the most useful methods of +raising water from streams. There are thousands of these in use in the +dry regions of the West. Small buckets are fastened to a large wheel, +which is turned by the current of a stream. As the wheel turns, the +buckets are filled, raised, and then emptied into a trough called a +flume. The water flows through the flume into the irrigating ditches, +which distribute it as it is needed in the fields. In some parts of +California and other comparatively dry sections, wells are sunk in or +near the beds of underground streams, and then the water is pumped into +ditches which convey it to the fields to be irrigated. + +Engines are often used for pumping water from streams and transferring +it to ditches or canals. The canals distribute the water over the land +or over the growing crops. + +[Illustration: FIG. 287. THE MAIN DITCH OF AN IRRIGATION PLANT] + +None of these methods, however, can be used for watering very large +areas of land. Hence, as the value of farm lands increased other methods +were sought. Shrewd men began to turn longing eyes on the wide stretches +of barren land in the West. They knew that these waste lands, seemingly +so unfertile, would become most fruitful as soon as water was turned on +them. Could water enough be found? New plans to pen up floods of water +were prepared, and immense sums were spent in carrying out these plans. +Enormous dams of cemented stone were thrown across the gorges in the +foothills of the mountains. Behind these solid dams the water from the +rains and the melting snow of the mountains was backed for miles, and +was at once ready to change barrenness into fruitfulness. The stored +water is led by means of main canals and cross ditches wherever it is +needed, and countless acres have been brought under cultivation. + +Water is generally applied either by making furrows for its passage +through the fields or by flooding the land. The latter plan is the +cheaper, but it can be used only on level lands. Where the land is +somewhat irregular a checking system, as it is called, is used to +distribute the water. It is taken from check to check until the entire +field has been irrigated. + +[Illustration: FIG. 288. THE PROCESS OF IRRIGATING CORN] + +The furrow method is usually employed for fruits and for farm and garden +crops. In many places the grass and grain crops are now supplied with +water by furrows instead of by flooding. + +Irrigated lands should be carefully and thoroughly tilled. The water for +irrigation is costly, and should be made to go as far as possible. Good +tillage saves the water. Moreover, all cultivated crops like corn, +potatoes, and orchard and truck crops ought to be cultivated frequently +to save the moisture, to keep the soil in fit condition, and to aid the +bacteria in the soil. It was a wise farmer who said, "One does not need +to grow crops many years in order to learn that nothing can take the +place of stirring the soil." + + +METHODS OF IRRIGATING CROPS + +_Tree fruits._ Water is conducted through very narrow furrows from three +to five feet apart, and allowed to sink about four feet deep, and to +spread under the ground. Then the supply is cut off. The object is to +wet the soil deeply, and then by tillage to hold the moisture in the +soil. + +_Small fruits._ The common practice is to run water on each side of the +row until the rows are soaked. + +_Potatoes._ A thorough soaking is given the land before planting-time, +and then no more than is absolutely necessary until blossoming-time. +After the blossoms appear keep the soil moist until the crop ripens. + +_Garden crops._ Any method may be employed, but the vital point is to +cultivate the ground as early as it can be worked after it has been +irrigated. + +_Meadows and alfalfa._ Flooding is the most common method in use. The +first irrigation comes early in the spring before growth has advanced +much, and the successive waterings after the harvesting of each crop. + + +SECTION LXX. LIFE IN THE COUNTRY + +As ours is a country in which the people rule, every boy and every girl +ought to be trained to take a wide-awake interest in public affairs. +This training cannot begin too early in life. A wise old man once said, +"In a republic you ought to begin to train a child for good citizenship +on the day of its birth." + +[Illustration: FIG. 289. BEAUTY FROM FLOWERS AND GRASS] + +[Illustration: FIG. 290. A COUNTRY ROAD IN MECKLENBURG COUNTY, +NORTH CAROLINA] + +Happy would it be for our nation if all the young people who live in the +country could begin their training in good citizenship by becoming +workers for these four things: + +First, attractive country homes. + +Second, attractive country schoolhouses and school grounds. + +Third, good country schools. + +Fourth, good roads. + +If the thousands on thousands of pupils in our schools would become +active workers for these things and continue their work through life, +then, in less than half a century, life in the country would be an +unending delight. + +One of the problems of our day is how to keep bright, thoughtful, +sociable, ambitious boys and girls contented on the farm. Every step +taken to make the country home more attractive, to make the school and +its grounds more enjoyable, to make the way easy to the homes of +neighbors, to school, to post-office, and to church, is a step taken +toward keeping on the farm the very boys and girls who are most apt to +succeed there. + +Not every man who lives in the country can have a showy or costly home, +but as long as grass and flowers and vines and trees grow, any man who +wishes can have an attractive house. Not every woman who is to spend a +lifetime at the head of a rural home can have a luxuriously furnished +home, but any woman who is willing to take a little trouble can have a +cozy, tastefully furnished home--a home fitted with the conveniences +that diminish household drudgery. Even in this day of cheap literature, +all parents cannot fill their children's home with papers, magazines, +and books, but by means of school and Sunday-school libraries, by means +of circulating book clubs, and by a little self-denial, earnest parents +can feed hungry minds just as they feed hungry bodies. + +[Illustration: THE QUEEN OF FLOWERS FOR THE HOME] + +[Illustration: FIG. 291. AN ATTRACTIVE COUNTRY HOME] + +Agricultural papers that arouse the interest and quicken the thought of +farm boys by discussing the best, easiest, and cheapest ways of farming; +journals full of dainty suggestions for household adornment and comfort; +illustrated papers and magazines that amuse and cheer every member of +the family; books that rest tired bodies and open and strengthen growing +minds--all of these are so cheap that the money reserved from the sale +of one hog will keep a family fairly supplied for a year. + +[Illustration: FIG. 292. AN UNIMPROVED SCHOOLHOUSE] + +[Illustration: FIG. 293. AN IMPROVED SCHOOLHOUSE] + +[Illustration: FIG. 294. THE SAME ROAD AFTER AND BEFORE IMPROVEMENT] + +If the parents, teachers, and pupils of a school join hands, an +unsightly, ill-furnished, ill-lighted, and ill-ventilated school-house +can at small cost be changed into one of comfort and beauty. In many +places pupils have persuaded their parents to form clubs to beautify the +school grounds. Each father sends a man or a man with a plow once or +twice a year to work a day on the grounds. Stumps are removed, trees +trimmed, drains put in, grass sowed, flowers, shrubbery, vines, and +trees planted, and the grounds tastefully laid off. Thus at scarcely +noticeable money cost a rough and unsightly school ground gives place to +a charming school yard. Cannot the pupils in every school in which this +book is studied get their parents to form such a club, and make their +school ground a silent teacher of neatness and beauty? + +[Illustration: FIG. 295. WASHINGTON'S COUNTRY HOME] + +Life in the country will never be as attractive as it ought to be until +all the roads are improved. Winter-washed roads, penning young people +in their own homes for many months each year and destroying so many of +the innocent pleasures of youth, build towns and cities out of the wreck +of country homes. Can young people who love their country and their +country homes engage in a nobler crusade than a crusade for improved +highways? + + + + +APPENDIX + + +SPRAYING MIXTURES + +FOR BITING INSECTS + +DRY PARIS GREEN + + Paris green 1 lb. + Lime or flour 4 to 16 lb. + +WET PARIS GREEN + + Paris green 1/4 to 2 lb. + Lime 1/4 to 1/2 lb. + Water 50 gal. + +FOR SOFT-BODIED SUCKING INSECTS + +KEROSENE EMULSION + + Hard soap (in fine shavings) 1/2 lb. + Soft water 1 gal. + Kerosene 2 gal. + +Dissolve soap in boiling water, add kerosene to the hot water, churn +with spraying pump for at least ten minutes, until the mixture changes +to a creamy, then to a soft, butterlike, mass. This gives three gallons +of 66-per-cent oil emulsion, which may be diluted to the strength +desired. To get 15-per-cent oil emulsion add ten and one-half gallons of +water. + +FOR FUNGOUS DISEASES + +COPPER SULPHATE + + Copper sulphate 1 lb. + Water 18 to 25 gal. + +Use only before foliage opens, to kill wintering spores. + +BORDEAUX MIXTURE + + Copper sulphate (bluestone) 4 to 5 lb. + Lime (good, unslaked) 5 to 6 lb. + Water 50 gal. + +Dissolve the copper sulphate (bluestone) in twenty-five gallons of +water. Slake the lime slowly so as to get a smooth, thick cream. Never +cover the lime with too much water. After thorough slaking add +twenty-five gallons of water. When the lime and the bluestone have +dissolved, pour the two liquids into a third vessel. Be sure that each +stream mixes with the other before either enters the vessel. Strain +through a coarse cloth. + +Mix fresh for each time. Use for molds and fungi generally. Apply in +fine spray with a good nozzle. + +BORDEAUX-PARIS-GREEN MIXTURE + + Ordinary Bordeaux mixture 50 gal. + Paris green 4 oz. to 2 lb. + +Use for both fungi and insects on apple, potato, etc. + +BORDEAUX-ARSENATE-OF-LEAD MIXTURE + + Ordinary Bordeaux mixture 50 gal. + Arsenate of lead 2 to 3 lb. + +Used for fungous and insect enemies of the potato, and of the apple when +bitter rot is troublesome. + +COMMERCIAL LIME-SULPHUR ARSENATE OF LEAD + + Commercial lime-sulphur 1-1/2 gal. + Arsenate of lead 2 to 3 lb. + Water 50 gal. + +Use for spraying apples. + +AMMONIACAL COPPER CARBONATE + + Copper carbonate 5 oz. + Ammonia (26° Baumé) about 3 pt. + Water 50 gal. + +Dissolve the copper carbonate in the smallest possible amount of +ammonia. This solution may be kept in stock and diluted to the proper +strength as needed. + +Use this instead of the Bordeaux mixture after the fruit has reached +half or two thirds of the mature size. It leaves no spots as does the +lime-sulphur wash or the Bordeaux mixture. + + +SPRAYS FOR BOTH FUNGOUS AND INSECT PESTS + +HOME-MADE LIME-SULPHUR WASH + + Lime 20 lb. + Sulphur 15 lb. + Water 50 gal. + +The lime, the sulphur, and about half of the water required are boiled +together for forty-five minutes in a kettle over a fire, or in a barrel +or other suitable tank by steam, strained, and then diluted to 50 +gallons. This is the wash regularly used against the San Jose scale. It +may be substituted for Bordeaux mixture when spraying trees in the +dormant state. Commercial lime-sulphur may also be used in place of this +homemade wash. Use one gallon of the commercial lime-sulphur to nine +gallons of water in the dormant season. + + +SELF-BOILED LIME-SULPHUR WASH + +The self-boiled lime-sulphur wash is a combination of lime and sulphur +boiled only by the heat of the slaking lime, and is used chiefly for +summer spraying on peaches, plums, cherries, etc. as a substitute for +the Bordeaux mixture. + + Lime 8 lb. + Sulphur 6 to 8 lb. + Water 50 gal. + +The lime should be placed in a barrel and enough water poured on it to +start it slaking and to keep the sulphur off the bottom of the barrel. +The sulphur, which should first be worked through a sieve to break up +the lumps, may then be added, and, finally, enough water to slake the +lime into a paste. Considerable stirring is necessary to prevent caking +on the bottom. After the violent boiling which accompanies the slaking +of the lime is over, the mixture should be diluted ready for use, or at +least enough cold water added to stop the cooking. From five to fifteen +minutes are required for the process. If the hot mass is permitted to +stand undiluted as a thick paste, a liquid is produced that is injurious +to peach foliage and, in some cases, to apple foliage. + +The mixture should be strained through a sieve of twenty meshes to the +inch in order to remove the coarse particles of lime, but all the +sulphur should be worked through the strainer. + + + + +GLOSSARY + + +To enable young readers to understand the technical words necessarily +used in the text only popular definitions are given. + + +=Abdomen=: the part of an insect lying behind the thorax. + +=Acid=: a chemical name given to many sour substances.

Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg-tm depends upon and cannot survive without wide +spread public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To +SEND DONATIONS or determine the status of compliance for any +particular state visit http://pglaf.org + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg Web pages for current donation +methods and addresses. Donations are accepted in a number of other +ways including checks, online payments and credit card donations. +To donate, please visit: http://pglaf.org/donate + + +Section 5. General Information About Project Gutenberg-tm electronic +works. + +Professor Michael S. Hart is the originator of the Project Gutenberg-tm +concept of a library of electronic works that could be freely shared +with anyone. For thirty years, he produced and distributed Project +Gutenberg-tm eBooks with only a loose network of volunteer support. + + +Project Gutenberg-tm eBooks are often created from several printed +editions, all of which are confirmed as Public Domain in the U.S. +unless a copyright notice is included. Thus, we do not necessarily +keep eBooks in compliance with any particular paper edition. + + +Most people start at our Web site which has the main PG search facility: + + http://www.gutenberg.org + +This Web site includes information about Project Gutenberg-tm, +including how to make donations to the Project Gutenberg Literary +Archive Foundation, how to help produce our new eBooks, and how to +subscribe to our email newsletter to hear about new eBooks. diff --git a/20772-8.zip b/20772-8.zip Binary files differnew file mode 100644 index 0000000..75fda2d --- /dev/null +++ b/20772-8.zip diff --git a/20772-h.zip b/20772-h.zip Binary files differnew file mode 100644 index 0000000..8b289fb --- /dev/null +++ b/20772-h.zip diff --git a/20772-h/20772-h.htm b/20772-h/20772-h.htm new file mode 100644 index 0000000..2cfa6cb --- /dev/null +++ b/20772-h/20772-h.htm @@ -0,0 +1,11796 @@ +<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" + "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> + +<html xmlns="http://www.w3.org/1999/xhtml"> + <head> + <meta http-equiv="Content-Type" content="text/html;charset=iso-8859-1" /> + <title> + The Project Gutenberg eBook of Agriculture for Beginners, by Charles William Burkett. + </title> + <style type="text/css"> +/*<![CDATA[ XML blockout */ +<!-- + p { margin-top: .75em; + text-align: justify; + margin-bottom: .75em; + } + h1,h2,h3,h4,h5,h6 { + text-align: center; /* all headings centered */ + clear: both; + } + hr { width: 33%; + margin-top: 2em; + margin-bottom: 2em; + margin-left: auto; + margin-right: auto; + clear: both; + } + + div.centered {text-align: center;} /* work around for IE centering with CSS problem part 1 */ + div.centered table {margin-left: auto; margin-right: auto; text-align: left;} /* work around for IE centering with CSS problem part 2 */ + + + body{margin-left: 10%; + margin-right: 10%; + } + + img {border:0;} + + .pagenum { /* uncomment the next line for invisible page numbers */ + /* visibility: hidden; */ + position: absolute; + left: 92%; + font-size: smaller; + text-align: right; + } /* page numbers */ + + .linenum {position: absolute; top: auto; left: 4%;} /* poetry number */ + .blockquot{margin-left: 5%; margin-right: 10%;} + + .bb {border-bottom: solid 2px;} + .bl {border-left: solid 2px;} + .bt {border-top: solid 2px;} + .br {border-right: solid 2px;} + .bbox {border: solid 2px;} + + .center {text-align: center;} + .smcap {font-variant: small-caps; font-size: 85%;} + .u {text-decoration: underline;} + + .caption {font-weight: bold;} + + .figcenter {margin: auto; text-align: center;} + + .figleft {float: left; clear: left; margin-left: 0; margin-bottom: 1em; margin-top: + 1em; margin-right: 1em; padding: 0; text-align: center;} + + .figright {float: right; clear: right; margin-left: 1em; margin-bottom: 1em; + margin-top: 1em; margin-right: 0; padding: 0; text-align: center;} + + .footnotes {border: dashed 1px;} + .footnote {margin-left: 10%; margin-right: 10%; font-size: 0.9em;} + .footnote .label {position: absolute; right: 84%; text-align: right;} + .fnanchor {vertical-align: super; font-size: .8em; text-decoration: none;} + + .poem {margin-left:10%; margin-right:10%; text-align: left;} + .poem br {display: none;} + .poem .stanza {margin: 1em 0em 1em 0em;} + .poem span.i0 {display: block; margin-left: 0em; padding-left: 3em; text-indent: -3em;} + .poem span.i2 {display: block; margin-left: 2em; padding-left: 3em; text-indent: -3em;} + .poem span.i4 {display: block; margin-left: 4em; padding-left: 3em; text-indent: -3em;} + // --> + /* XML end ]]>*/ + </style> + </head> +<body> + + +<pre> + +The Project Gutenberg EBook of Agriculture for Beginners, by +Charles William Burkett and Frank Lincoln Stevens and Daniel Harvey Hill + +This eBook is for the use of anyone anywhere at no cost and with +almost no restrictions whatsoever.

Naturally many suggestions as +to changes, additions, and other improvements have reached its authors. +Naturally, too, the authors have busied themselves in devising methods +to add to the effectiveness of the book. Some additions have been made +almost every year since the book was published. To embody all these +changes and helpful suggestions into a strictly unified volume; to add +some further topics and sections; to bring all farm practices up to the +ideals of to-day; to include the most recent teaching of scientific +investigators—these were the objects sought in the thorough revision +which has just been given the book. The authors hope and think that the +remaking of the book has added to its usefulness and attractiveness.</p> + +<p>They believe now, as they believed before, that there is no line of +separation between the science of agriculture and the practical art of +agriculture. They are assured by the success of this book that +agriculture is eminently a teachable subject. They see no difference +between teaching the child the fundamental principles of farming and +teaching the same child the fundamental truths of arithmetic, geography, +or grammar. They hold that a youth should be trained for the farm just +as carefully as he is trained for any other occupation, and that it is +unreasonable to expect him to succeed without training.</p> + +<p>If they are right in these views, the training must begin in the public +schools. This is true for two reasons:</p> + +<p>1. It is universally admitted that aptitudes are developed, tastes +acquired, and life habits formed during the years that a child is in the +public school. Hence, during these important years every child intended +for the farm should be taught to know and love nature, should be led to +form habits of observation, and should be required to begin a study of +those great laws upon which agriculture is based. A training like this +goes far toward making his life-work profitable and delightful.</p> + +<p>2. Most boys and girls reared on a farm get no educational training +except that given in the public schools. If, then, the truths that +unlock the doors of nature are not taught in the public schools, nature +and nature's laws will always be hid in night to a majority of our +bread-winners. They must still in ignorance and hopeless drudgery tear +their bread from a reluctant soil.</p> + +<p>The authors return hearty thanks to Professor Thomas F. Hunt, University +of California; Professor Augustine D. Selby, Ohio Experiment Station; +Professor W. F. Massey, horticulturist and agricultural writer; and +Professor Franklin Sherman, Jr., State Entomologist of North Carolina, +for aid in proofreading and in the preparation of some of the material.</p> + +<hr style="width: 65%;" /> + +<h2><br /><br />CONTENTS<br /><br /></h2> + + +<div class='centered'> +<table border="0" cellpadding="2" width="85%" cellspacing="0" summary="CONTENTS"> +<tr><td> </td><th align='center' colspan="2">CHAPTER I.

By the same reasoning they might hesitate to teach +arithmetic because they do not know calculus or to teach a primary +history of the United States because they are not versed in all history. +The art of farming is based on the sciences dealing with the growth of +plants and animals. This book presents in a simple way these fundamental +scientific truths and suggests some practices drawn from them. Hence, +even though many teachers may not have plowed or sowed or harvested, +such teachers need not be embarrassed in mastering and heartily +instructing a class in nature's primary laws.</p> + +<p>If teachers realize how much the efficiency, comfort, and happiness of +their pupils will be increased throughout their lives from being taught +to coöperate with nature and to take advantage of her wonderful laws, +they will eagerly begin this study. They will find also that their +pupils will be actively interested in these studies bearing on their +daily lives, and this interest will be carried over to other subjects. +Whenever you can, take the pupils into the field, the garden, the +orchard, and the dairy. Teach them to make experiments and to learn by +the use of their own eyes and brains. They will, if properly led, +astonish you by their efforts and growth.</p> + +<p>You will find in the practical exercises many suggestions as to +experiments that you can make with your class or with individual +members. Do not neglect this first-hand teaching. It will be a delight +to your pupils. In many cases it will be best to finish the experiments +or observational work first, and later turn to the text to amplify the +pupil's knowledge.</p> + +<p>Although the book is arranged in logical order, the teacher ought to +feel free to teach any topic in the season best suited to its study. +Omit any chapter or section that does not bear on your crops or does not +deal with conditions in your state.</p> + +<p>The United States government and the different state experiment stations +publish hundreds of bulletins on agricultural subjects. These are sent +without cost, on application. It will be very helpful to get such of +these bulletins as bear on the different sections of the book. These +will be valuable additions to your school library. The authors would +like to give a list of these bulletins bearing on each chapter, but it +would soon be out of date, for the bulletins get out of print and are +supplanted by newer ones. However, the United States Department of +Agriculture prints a monthly list of its publications, and each state +experiment station keeps a list of its bulletins. A note to the +Secretary of Agriculture, Washington, D.C., or to your own state +experiment station will promptly bring you these lists, and from them +you can select what you need for your school.<span class='pagenum'><a name="Page_1" id="Page_1">[Pg 1]</a></span></p> + + + +<hr style="width: 65%;" /> +<h2><br /><br /><a name="AGRICULTURE_FOR_BEGINNERS" id="AGRICULTURE_FOR_BEGINNERS"></a>AGRICULTURE FOR BEGINNERS<br /><br /><br /></h2> +<hr style="width: 65%;" /> +<h2>CHAPTER I</h2> + +<h2>THE SOIL</h2> + + +<h3>SECTION I. ORIGIN OF THE SOIL</h3> + +<p>The word <i>soil</i> occurs many times in this little book. In agriculture +this word is used to describe the thin layer of surface earth that, like +some great blanket, is tucked around the wrinkled and age-beaten form of +our globe. The harder and colder earth under this surface layer is +called the <i>subsoil</i>. It should be noted, however, that in waterless and +sun-dried regions there seems little difference between the soil and the +subsoil.</p> + +<p>Plants, insects, birds, beasts, men,—all alike are fed on what grows in +this thin layer of soil. If some wild flood in sudden wrath could sweep +into the ocean this earth-wrapping soil, food would soon become as +scarce as it was in Samaria when mothers ate their sons. The face of the +earth as we now see it, daintily robed in grass, or uplifting waving +acres of corn, or even naked, water-scarred, and disfigured by man's +neglect, is very different from what it was in its earliest days. How +was it then? How was the soil formed?</p> + +<p>Learned men think that at first the surface of the earth was solid rock. +How was this rock changed into workable soil? Occasionally a curious boy +picks up a rotten stone, squeezes it, and finds his hands filled with +dirt, or soil. Now,<span class='pagenum'><a name="Page_2" id="Page_2">[Pg 2]</a></span> just as the boy crumbled with his fingers this +single stone, the great forces of nature with boundless patience +crumbled, or, as it is called, disintegrated, the early rock mass. The +simple but giant-strong agents that beat the rocks into powder with a +clublike force a millionfold more powerful than the club force of +Hercules were chiefly (1) heat and cold; (2) water, frost, and ice; (3) +a very low form of vegetable life; and (4) tiny animals—if such minute +bodies can be called animals. In some cases these forces acted singly; +in others, all acted together to rend and crumble the unbroken stretch +of rock. Let us glance at some of the methods used by these skilled +soil-makers.</p> + +<p>Heat and cold are working partners. You already know that most hot +bodies shrink, or contract, on cooling. The early rocks were hot. As the +outside shell of rock cooled from exposure to air and moisture it +contracted. This shrinkage of the rigid rim of course broke many of the +rocks, and here and there left cracks, or fissures. In these fissures +water collected and froze. As freezing water expands with irresistible +power, the expansion still further broke the rocks to pieces. The +smaller pieces again, in the same way, were acted on by frost and ice +and again crumbled. This process is still a means of soil-formation.</p> + +<p>Running water was another giant soil-former. If you would understand its +action, observe some usually sparkling stream just after a washing rain. +The clear waters are discolored by mud washed in from the surrounding +hills. As though disliking their muddy burden, the waters strive to +throw it off. Here, as low banks offer chance, they run out into +shallows and drop some of it. Here, as they pass a quiet pool, they +deposit more. At last they reach the still water at the mouth of the +stream, and there they leave behind the last of their<span class='pagenum'><a name="Page_3" id="Page_3">[Pg 3]</a></span> mud load, and +often form of it little three-sided islands called <i>deltas</i>. In the same +way mighty rivers like the Amazon, the Mississippi, and the Hudson, when +they are swollen by rain, bear great quantities of soil in their sweep +to the seas. Some of the soil they scatter over the lowlands as they +whirl seaward; the rest they deposit in deltas at their mouths. It is +estimated that the Mississippi carries to the ocean each year enough +soil to cover a square mile of surface to a depth of two hundred and +sixty-eight feet.</p> + + +<p><a name="img014" id="img014"></a></p> +<div class="figcenter"> + <img src="images/img014.jpg" + alt="Fig. 1." /><br /> + <b><span class="smcap">Fig. 1. Rock marked by the Scraping of a Glacier over +it</span></b> + </div> + + + +<p>The early brooks and rivers, instead of bearing mud, ran oceanward +either bearing ground stone that they themselves had worn from the rocks +by ceaseless fretting, or bearing stones that other forces had already +dislodged. The large pieces were whirled from side to side and beaten +against one another or against bedrock until they were ground into +smaller and smaller pieces. The rivers distributed this rock<span class='pagenum'><a name="Page_4" id="Page_4">[Pg 4]</a></span> soil just +as the later rivers distribute muddy soil. For ages the moving waters +ground against the rocks. Vast were the waters; vast the number of +years; vast the results.</p> + +<p>Glaciers were another soil-producing agent. Glaciers are streams "frozen +and moving slowly but irresistibly onwards, down well-defined valleys, +grinding and pulverizing the rock masses detached by the force and +weight of their attack." Where and how were these glaciers formed?</p> + +<p>Once a great part of upper North America was a vast sheet of ice. +Whatever moisture fell from the sky fell as snow. No one knows what made +this long winter of snow, but we do know that snows piled on snows until +mountains of white were built up. The lower snow was by the pressure of +that above it packed into ice masses. By and by some change of climate +caused the masses of ice to break up somewhat and to move south and +west. These moving masses, carrying rock and frozen earth, ground them +to powder. King thus describes the stately movement of these snow +mountains: "Beneath the bottom of this slowly moving sheet of ice, which +with more or less difficulty kept itself conformable with the face of +the land over which it was riding, the sharper outstanding points were +cut away and the deeper river cañons filled in. Desolate and rugged +rocky wastes were thrown down and spread over with rich soil."</p> + +<p>The joint action of air, moisture, and frost was still another agent of +soil-making. This action is called <i>weathering</i>. Whenever you have +noticed the outside stones of a spring-house, you have noticed that tiny +bits are crumbling from the face of the stones, and adding little by +little to the soil. This is a slow way of making additions to the soil. +It is estimated that it would take 728,000 years to wear away limestone +rock to<span class='pagenum'><a name="Page_5" id="Page_5">[Pg 5]</a></span> a depth of thirty-nine inches. But when you recall the +countless years through which the weather has striven against the rocks, +you can readily understand that its never-wearying activity has added +immensely to the soil.</p> + +<p>In the rock soil formed in these various ways, and indeed on the rocks +themselves, tiny plants that live on food taken from the air began to +grow. They grew just as you now see mosses and lichens grow on the +surface of rocks. The decay of these plants added some fertility to the +newly formed soil. The life and death of each succeeding generation of +these lowly plants added to the soil matter accumulating on the rocks. +Slowly but unceasingly the soil increased in depth until higher +vegetable forms could flourish and add their dead bodies to it. This +vegetable addition to the soil is generally known as <i>humus</i>.</p> + + +<div class="figcenter"> + <img src="images/img016.jpg" + alt="Fig. 2." /><br /> + <b><span class="smcap">Fig. 2. Ground Rock at End of a Glacier</span></b> + </div> + +<p>In due course of time low forms of animal life came to live on these +plants, and in turn by their work and their death to aid in making a +soil fit for the plowman.<span class='pagenum'><a name="Page_6" id="Page_6">[Pg 6]</a></span></p> + +<p>Thus with a deliberation that fills man with awe, the powerful forces of +nature splintered the rocks, crumbled them, filled them with plant food, +and turned their flinty grains into a soft, snug home for vegetable +life.</p> + + +<h3>SECTION II. TILLAGE OF THE SOIL</h3> + +<p>A good many years ago a man by the name of Jethro Tull lived in England. +He was a farmer and a most successful man in every way. He first taught +the English people and the world the value of thorough tillage of the +soil. Before and during his time farmers did not till the soil very +intelligently. They simply prepared the seed-bed in a careless manner, +as a great many farmers do to-day, and when the crops were gathered the +yields were not large.</p> + +<p>Jethro Tull centered attention on the important fact that careful and +thorough tillage increases the available plant food in the soil. He did +not know why his crops were better when the ground was frequently and +thoroughly tilled, but he knew that such tillage did increase his yield. +He explained the fact by saying, "Tillage is manure." We have since +learned the reason for the truth that Tull taught, and, while his +explanation was incorrect, the practice that he was following was +excellent. The stirring of the soil enables the air to circulate through +it freely, and permits a breaking down of the compounds that contain the +elements necessary to plant growth.</p> + +<p>You have seen how the air helps to crumble the stone and brick in old +buildings. It does the same with soil if permitted to circulate freely +through it. The agent of the air that chiefly performs this work is +called carbonic acid gas, and this gas is one of the greatest helpers +the farmer has in carrying on<span class='pagenum'><a name="Page_7" id="Page_7">[Pg 7]</a></span> his work. We must not forget that in soil +preparation the air is just as important as any of the tools and +implements used in cultivation.</p> + +<p><a name="img018" id="img018"></a></p> +<div class="figcenter"> + <img src="images/img018.jpg" + alt="Fig. 3." /><br /> + <b><span class="smcap">Fig. 3. Slope to Water shows Soil weathered from Face +of Cliff</span></b> + </div> + + +<p>If the soil is fertile and if deep plowing has always been done, good +crops will result, other conditions being favorable. If, however, the +tillage is poor, scanty harvests will always result. For most soils a +two-horse plow is necessary to break up and pulverize the land.</p> + +<p>A shallow soil can always be improved by properly deepening it. The +principle of greatest importance in soil-preparation<span class='pagenum'><a name="Page_8" id="Page_8">[Pg 8]</a></span> is the gradual +deepening of the soil in order that plant-roots may have more +comfortable homes. If the farmer has been accustomed to plow but four +inches deep, he should adjust the plow so as to turn five inches at the +next plowing, then six, and so on until the seed-bed is nine or ten +inches deep. This gradual deepening will not injure the soil but will +put it quickly in good condition. If to good tillage rotation of crops +be added, the soil will become more fertile with each succeeding year.</p> + +<p><a name="img019" id="img019"></a></p> +<div class="figcenter"> + <img src="images/img019.jpg" + alt="Fig. 4." /><br /> + <b><span class="smcap">Fig. 4. Mixed Grasses Grown for Forage</span></b> + </div> + +<p>The plow, harrow, and roller are all necessary to good tillage and to a +proper preparation of the seed-bed. The soil must be made compact and +clods of all sizes must be crushed. Then the air circulates freely, and +paying crops are the rule and not the exception.</p> + +<p>Tillage does these things: it increases the plant-food supply, destroys +weeds, and influences the moisture content of the soil.<span class='pagenum'><a name="Page_9" id="Page_9">[Pg 9]</a></span></p> + + + +<div class="blockquot"><p style="margin-top: 2em;"><b>EXERCISE</b></p> + +<p>1.

Name three things that tillage does.</p></div> + + +<h3>SECTION III. THE MOISTURE OF THE SOIL</h3> + +<p>Did any one ever explain to you how important water is to the soil, or +tell you why it is so important? Often, as you know, crops entirely fail +because there is not enough water in the soil for the plants to drink. +How necessary is it, then, that the soil be kept in the best possible +condition to catch and hold enough water to carry the plant through dry, +hot spells! Perhaps you are ready to ask, "How does the mouthless plant +drink its stored-up water?"</p> + +<p>The plant gets all its water through its roots. You have seen the tiny +threadlike roots of a plant spreading all about in fine soil; they are +down in the ground taking up plant food and water for the stalk and +leaves above. The water, carrying plant food with it, rises in a simple +but peculiar way through the roots and stems.</p> + +<p>The plants use the food for building new tissue, that is, for growth. +The water passes out through the leaves into the air. When the summers +are dry and hot and there is<span class='pagenum'><a name="Page_10" id="Page_10">[Pg 10]</a></span> but little water in the soil, the leaves +shrink up. This is simply a method they have of keeping the water from +passing too rapidly off into the air. I am sure you have seen the corn +blades all shriveled on very hot days. This shrinkage is nature's way of +diminishing the current of water that is steadily passing through the +plant.</p> + +<p>A thrifty farmer will try to keep his soil in such good condition that +it will have a supply of water in it for growing crops when dry and hot +weather comes. He can do this by deep plowing, by subsoiling, by adding +any kind of decaying vegetable matter to the soil, and by growing crops +that can be tilled frequently.</p> + +<p>The soil is a great storehouse for moisture. After the clouds have +emptied their waters into this storehouse, the water of the soil comes +to the surface, where it is evaporated into the air. The water comes to +the surface in just the same way that oil rises in a lamp-wick. This +rising of the water is called <i>capillarity</i>.</p> + +<p><a name="img021" id="img021"></a></p> +<div class="figcenter"> + <img src="images/img021.jpg" + alt="Fig. 5." /><br /> + <b><span class="smcap">Fig. 5. An Enlarged View of a Section of Moist Soil, +showing Air Spaces and Soil Particles</span></b> + </div> + +<p>It is necessary to understand what is meant by this big word. If into a +pan of water you dip a glass tube, the water inside the tube rises above +the level of the water in the pan. The smaller the tube the higher will +the water rise. The greater rise inside is perhaps due to the fact that +the glass attracts the particles of water more than the particles of +water attract one another. Now apply this principle to the soil.</p> + + +<div class="figcenter"> + <img src="images/img022.jpg" width="500" height="321" + alt="Fig. 6." /><br /> + <b><span class="smcap">Fig. 6.

Capillarity brought the water to the surface, +and the plank, by keeping away wind and warmth, acted as a trap to hold +the moisture.

The water was stored in the soil during the fall, winter, and +spring months when there was plenty of rain. If you dig down into the +soil when everything is dry and hot, you will soon reach a cool, moist +undersoil. The moisture increases as you dig deeper into the soil.<span class='pagenum'><a name="Page_14" id="Page_14">[Pg 14]</a></span></p> + +<p>Now the roots of plants go down into the soil for this moisture, because +they need the water to carry the plant food up into the stems and +leaves.</p> + +<p>You can see how the water rises in the soil by performing a simple +experiment.</p> + + +<div class="blockquot"><p style="margin-top: 2em;"><b>EXPERIMENT</b></p> + +<p>Take a lamp-chimney and fill it with fine, dry dirt.

DRAINING THE SOIL</h3> + +<p>A wise man was once asked, "What is the most valuable improvement ever +made in agriculture?" He answered, "Drainage." Often soils unfit for +crop-production because they contain too much water are by drainage +rendered the most valuable of farming lands.</p> + +<p>Drainage benefits land in the following ways:</p> + +<p>1. It deepens the subsoil by removing unnecessary water from the spaces +between the soil particles. This admits air. Then the oxygen which is in +the air, by aiding decay, prepares plant food for vegetation.</p> + +<p>2. It makes the surface soil, or topsoil, deeper. It stands to reason +that the deeper the soil the more plant food becomes available for plant +use.<span class='pagenum'><a name="Page_15" id="Page_15">[Pg 15]</a></span></p> + +<p>3. It improves the texture of the soil. Wet soil is sticky. Drainage +makes this sticky soil crumble and fall apart.</p> + +<p>4. It prevents washing.</p> + +<p>5. It increases the porosity of soils and permits roots to go deeper +into the soil for food and moisture.</p> + +<p>6. It increases the warmth of the soil.</p> + +<p>7. It permits earlier working in spring and after rains.</p> + +<p><a name="img026" id="img026"></a></p> +<div class="figcenter"> + <img src="images/img026.jpg" + alt="Fig. 9." /><br /> + <b><span class="smcap">Fig. 9.

It favors the growth of germs which change the unavailable nitrogen +of the soil into nitrates; that is, into the form of nitrogen most +useful to plants.</p> + +<p>9. It enables plants to resist drought better because the roots go into +the ground deeper early in the season.</p> + +<p>A soil that is hard and wet will not grow good crops. The +nitrogen-gathering crops will store the greatest quantity of nitrogen in +the soil when the soil is open to the free<span class='pagenum'><a name="Page_16" id="Page_16">[Pg 16]</a></span> circulation of the air. +These valuable crops cannot do this when the soil is wet and cold.</p> + +<p>Sandy soils with sandy subsoils do not often need drainage; such soils +are naturally drained. With clay soils it is different. It is very +important to remove the stagnant water in them and to let the air in.</p> + +<p>When land has been properly drained the other steps in improvement are +easily taken. After soil has been dried and mellowed by proper drainage, +then commercial fertilizers, barnyard manure, cowpeas, and clover can +most readily do their great work of improving the texture of the soil +and of making it fitter for plant growth.</p> + +<div class="figcenter"> + <img src="images/img027.jpg" width="300" height="239" + alt="Fig. 10." /><br /> + <b><span class="smcap">Fig. 10.

IMPROVING THE SOIL</h3> + +<p>We hear a great deal about the exhaustion or wearing out of the soil. +Many uncomfortable people are always declaring that our lands will no +longer produce profitable crops, and hence that farming will no longer +pay.</p> + +<p>Now it is true, unfortunately, that much land has been robbed of its +fertility, and, because this is true, we should be most deeply +interested in everything that leads to the improvement of our soils.</p> + +<p>When our country was first discovered and trees were growing everywhere, +we had virgin soils, or new soils that<span class='pagenum'><a name="Page_18" id="Page_18">[Pg 18]</a></span> were rich and productive because +they were filled with vegetable matter and plant food. There are not +many virgin soils now because the trees have been cut from the best +lands, and these lands have been farmed so carelessly that the vegetable +matter and available plant food have been largely used up. Now that +fresh land is scarce it is very necessary to restore fertility to these +exhausted lands. What are some of the ways in which this can be done?</p> + +<div class="figcenter"> + <img src="images/img029.jpg" width="500" height="411" + alt="Fig. 11." /><br /> + <b><span class="smcap">Fig. 11. Clover is a Soil-Improver</span></b> + </div> + +<p>There are several things to be done in trying to reclaim worn-out land. +One of the first of these is to till the land well. Many of you may have +heard the story of the dying father who called his sons about him and +whispered feebly, "There is great treasure hidden in the garden." The +sons could hardly wait to bury their dead father before, thud,<span class='pagenum'><a name="Page_19" id="Page_19">[Pg 19]</a></span> thud, +thud, their picks were going in the garden. Day after day they dug; they +dug deep; they dug wide. Not a foot of the crop-worn garden escaped the +probing of the pick as the sons feverishly searched for the expected +treasure. But no treasure was found. Their work seemed entirely useless.</p> + + +<div class="figcenter"> + <img src="images/img030.jpg" width="500" height="406" + alt="Fig. 12." /><br /> + <b><span class="smcap">Fig. 12. Increasing the Productive Power of the +Soil</span><br />Second crop of cowpeas on old, abandoned land</b> + </div> + + +<p>"Let us not lose every whit of our labor; let us plant this pick-scarred +garden," said the eldest. So the garden was planted. In the fall the +hitherto neglected garden yielded a harvest so bountiful, so unexpected, +that the meaning of their father's words dawned upon them. "Truly," they +said, "a treasure was hidden there. Let us seek it in all our fields."<span class='pagenum'><a name="Page_20" id="Page_20">[Pg 20]</a></span></p> + +<p>The story applies as well to-day as it did when it was first told. +Thorough culture of the soil, frequent and intelligent tillage—these +are the foundations of soil-restoration.</p> + +<p>Along with good tillage must go crop-rotation and good drainage. A +supply of organic matter will prevent heavy rains from washing the soil +and carrying away plant food. Drainage will aid good tillage in allowing +air to circulate between the soil particles and in arranging plant food +so that plants can use it.</p> + +<p>But we must add humus, or vegetable matter, to the soil. You remember +that the virgin soils contained a great deal of vegetable matter and +plant food, but by the continuous growing of crops like wheat, corn, and +cotton, and by constant shallow tillage, both humus and plant food have +been used up. Consequently much of our cultivated soil to-day is hard +and dead.</p> + +<p>There are three ways of adding humus and plant food to this lifeless +land: the first way is to apply barnyard manure (to adopt this method +means that livestock raising must be a part of all farming); the second +way is to adopt rotation of crops, and frequently to plow under crops +like clover and cowpeas; the third way is to apply commercial +fertilizers.</p> + +<p>To summarize: if we want to make our soil better year by year, we must +cultivate well, drain well, and in the most economical way add humus and +plant food.</p> + + +<div class="blockquot"><p style="margin-top: 2em;"><b>EXPERIMENT</b></p> + +<p>Select a small area of ground at your home and divide it into four +sections, as shown in the following sketch:</p> + +<div class="figright"> + <img src="images/img032.jpg" width="142" height="200" + alt="Fig. 13." /><br /> + <b><span class="smcap">Fig. 13.</span></b> + </div> + +<p>On Section <i>A</i> apply barnyard manure; on Section <i>B</i> apply +commercial fertilizers; on Section <i>C</i> apply nothing, but till +well; on Section <i>D</i> apply nothing, and till very poorly.<span class='pagenum'><a name="Page_21" id="Page_21">[Pg 21]</a></span></p> + +<p><i>A</i>, <i>B</i>, and <i>C</i> should all be thoroughly plowed and harrowed. +Then add barnyard manure to <i>A</i>, commercial fertilizers to <i>B</i>, and +harrow <i>A</i>, <i>B</i>, and <i>C</i> at least four times until the soil is +mellow and fine. <i>D</i> will most likely be cloddy, like many fields +that we often see. Now plant on each plat some crop like cotton, +corn, or wheat. When the plats are ready to harvest, measure the +yield of each and determine whether the increased yield of the best +plats has paid for the outlay for tillage and manure. The pupil +will be much interested in the results obtained from the first +crop.</p> + +<p>Now follow a system of crop-rotation on the plats. Clover can +follow corn or cotton or wheat; and cowpeas, wheat. Then determine +the yield of each plat for the second crop. By following these +plats for several years, and increasing the number, the pupils will +learn many things of greatest value.</p></div> + + +<h3>SECTION VII. MANURING THE SOIL</h3> + +<p>In the early days of our history, when the soil was new and rich, we +were not compelled to use large amounts of manures and fertilizers. Yet +our histories speak of an Indian named Squanto who came into one of the +New England colonies and showed the first settlers how, by putting a +fish in each hill of corn, they could obtain larger yields.</p> + +<p>If people in those days, with new and fertile soils, could use manures +profitably, how much more ought we to use them in our time, when soils +have lost their virgin fertility, and when the plant food in the soil +has been exhausted by years and years of cropping!<span class='pagenum'><a name="Page_22" id="Page_22">[Pg 22]</a></span></p> + +<p>To sell year after year all the produce grown on land is a sure way to +ruin it. If, for example, the richest land is planted every year in +corn, and no stable or farmyard manure or other fertilizer returned to +the soil, the land so treated will of course soon become too poor to +grow any crop. If, on the other hand, clover or alfalfa or corn or +cotton-seed meal is fed to stock, and the manure from the stock returned +to the soil, the land will be kept rich. Hence those farmers who do not +sell such raw products as cotton, corn, wheat, oats, and clover, but who +market articles made from these raw products, find it easier to keep +their land fertile. For illustration: if instead of selling hay, farmers +feed it to sheep and sell meat and wool; if instead of selling cotton +seed, they feed its meal to cows, and sell milk and butter; if instead +of selling stover, they feed it to beef cattle, they get a good price +for products and in addition have all the manure needed to keep their +land productive and increase its value each year.</p> + +<div class="figcenter"> + <img src="images/img033.jpg" width="400" height="250" + alt="Fig. 14." /><br /> + <b><span class="smcap">Fig. 14.

All the manures, straw, roots, +stubble, healthy vines—in fact everything decomposable—should be +plowed under or used as a top-dressing. Especial care should be taken in +storing manure. It should be watchfully protected from sun and rain. If +a farmer has no shed under which to keep his manure, he should scatter +it on his fields as fast as it is made.<span class='pagenum'><a name="Page_23" id="Page_23">[Pg 23]</a></span></p> + +<div class="figcenter"> + <img src="images/img034.jpg" width="500" height="451" + alt="Fig. 15." /><br /> + <b><span class="smcap">Fig. 15.

Some of the phosphoric acid and +considerable amounts of the potash are also found in the liquid manure. +Hence economy requires that none of this escape either by leakage or by +fermentation. Sometimes one can detect the smell of ammonia in the +stable. This ammonia is formed by the decomposition of the liquid +manure, and its loss should be checked by sprinkling some floats, acid +phosphate, or muck over the stable floor.<span class='pagenum'><a name="Page_24" id="Page_24">[Pg 24]</a></span></p> + +<p>Many farmers find it desirable to buy fertilizers to use with the manure +made on the farm. In this case it is helpful to understand the +composition, source, and availability of the various substances +composing commercial fertilizers. The three most valuable things in +commercial fertilizers are nitrogen, potash, and phosphoric acid.</p> + +<p>The nitrogen is obtained from (1) nitrate of soda mined in Chile, (2) +ammonium sulphate, a by-product of the gas works, (3) dried blood and +other by-products of the slaughter-houses, and (4) cotton-seed meal. +Nitrate of soda is soluble in water and may therefore be washed away +before being used by plants. For this reason it should be applied in +small quantities and at intervals of a few weeks.</p> + +<p>Potash is obtained in Germany, where it is found in several forms. It is +put on the market as muriate of potash, sulphate of potash, kainite, +which contains salt as an impurity, and in other impure forms. Potash is +found also in <i>unleached</i> wood ashes.</p> + +<p>Phosphoric acid is found in various rocks of Tennessee, Florida, and +South Carolina, and also to a large extent in bones. The rocks or bones +are usually treated with sulphuric acid. This treatment changes the +phosphoric acid into a form ready for plant use.</p> + +<p>These three kinds of plant food are ordinarily all that we need to +supply. In some cases, however, lime has to be added. Besides being a +plant food itself, lime helps most soils by improving the structure of +the grains; by sweetening the soil, thereby aiding the little living +germs called <i>bacteria</i>; by hastening the decay of organic matter; and +by setting free the potash that is locked up in the soil.<span class='pagenum'><a name="Page_25" id="Page_25">[Pg 25]</a></span></p> + + + +<hr style="width: 65%;" /> +<h2><a name="CHAPTER_II" id="CHAPTER_II"></a>CHAPTER II</h2> + +<h2>THE SOIL AND THE PLANT</h2> + + +<h3>SECTION VIII.

HOW THE PLANT FEEDS FROM THE SOIL</h3> + + +<p>Plants receive their nourishment from two sources—from the air and from +the soil. The soil food, or mineral food, dissolved in water, must reach +the plant through the root-hairs with which all plants are provided in +great numbers. Each of these hairs may be compared to a finger reaching +among the particles of earth for food and water. If we examine the +root-hairs ever so closely, we find no holes, or openings, in them. It +is evident, then, that no solid particles can enter the root-hairs, but +that all food must pass into the root in solution.</p> + +<p>An experiment just here will help us to understand how a root feeds.</p> + + +<div class="blockquot"><p style="margin-top: 2em;"><b>EXPERIMENT</b></p> + +<div class="figright"> + <img src="images/img040.jpg" width="72" height="150" + alt="Fig. 22." /><br /> + <b><span class="smcap">Fig. 22. Experiment<br />to show how Roots<br />take up +Food</span></b> + </div> +<p>Secure a narrow glass tube like the one in Fig. 22. If you cannot +get a tube, a narrow, straight lamp-chimney will, with a little +care, do nearly as well. From a bladder made soft by soaking, cut a +piece large enough to cover the end of the tube or chimney and to +hang over a little all around. Make the piece of bladder secure to +the end of the tube by wrapping tightly with a waxed thread, as at +B. Partly fill the tube with molasses (or it may be easier in case +you use a narrow tube to fill it before attaching the bladder). Put +the tube into a jar or bottle of water so placed that the level of +the molasses inside and the water outside will be the same. Fasten +the tube in this position and observe it frequently for three or +four hours. At the end of the time you should find that the +molasses in the tube has risen above the level of the liquid +outside. It may even overflow at the top. If you use the +lamp-chimney the rise will not be so clearly seen, since a greater +volume is required to fill the space in the chimney. This increase +in<span class='pagenum'><a name="Page_30" id="Page_30">[Pg 30]</a></span> the contents of the tube is due to the entrance of water from +the outside. The water has passed through the thin bladder, or +membrane, and has come to occupy space in the tube. There is also a +passage the other way, but the molasses can pass through the +bladder membrane so slowly that the passage is scarcely noticeable. +There are no holes, or openings, in the membrane, but still there +is a free passage of liquids in both directions, although the more +heavily laden solution must move more slowly.</p></div> + +<p>A root-hair acts in much the same way as the tube in our experiment, +with the exception that it is so made as to allow certain substances to +pass in only one direction, that is, toward the inside. The outside of +the root-hair is bathed in solutions rich in nourishment. The +nourishment passes from the outside to the inside through the delicate +membrane of the root-hair. Thus does food enter the plant-root. From the +root-hairs, foods are carried to the inside of the root.</p> + +<p>From this you can see how important it is for a plant to have fine, +loose soil for its root-hairs; also how necessary is the water in the +soil, since the food can be used only when it is dissolved in water.</p> + +<p>This passage of liquids from one side of a membrane to another is called +<i>osmosis</i>. It has many uses in the plant kingdom. We say a root takes +nourishment by osmosis.</p> + + +<h3>SECTION X. ROOT-TUBERCLES</h3> + +<p>Tubercle is a big word, but you ought to know how to pronounce it and +what is meant by root-tubercles.

The +clovers, cowpeas, vetches, soy beans, and alfalfa are all legumes. The +tubercles are little knotty, wart-like growths on the roots of the +plants just named. These tubercles are caused by tiny forms of life +called, as you perhaps already know, bacteria, or <i>germs</i>.</p> + +<div class="figcenter"> + <img src="images/img042.jpg" width="500" height="382" + alt="Fig. 23." /><br /> + <b><span class="smcap">Fig. 23.

Soy Beans and Cowpeas, Two Great +Soil-Improvers</span></b> + </div> + + +<p>In the earlier pages of this book you were told something about the food +of plants. One of the main elements of plant food, perhaps you remember, +is nitrogen. Just as soon as the roots of the leguminous plants begin to +push down into the soil, the bacteria, or germs that make the tubercles, +begin to build their homes on the roots, and in so doing they add +nitrogen to the soil. You now see the importance of growing such crops +as peas and clover on your land, for by their tubercles you can +constantly add plant food to the soil. Now this much-needed nitrogen is +the most costly part of the fertilizers that farmers buy every year. If +every farmer, then, would grow these tubercle-bearing crops, he would +rapidly add to the richness of his land and at the same time escape the +necessity of buying so much expensive fertilizer.<span class='pagenum'><a name="Page_33" id="Page_33">[Pg 33]</a></span></p> + + +<div class="blockquot"><p style="margin-top: 2em;"><b>EXPERIMENT</b></p> + +<p>Take a spade or shovel and dig carefully around the roots of a +cowpea and a clover plant; loosen the earth thoroughly and then +pull the plants up, being careful not to break off any of the +roots.

Do all leguminous plants have equal numbers of +nodules? How do these nodules help the farmer?</p></div> + + +<h3>SECTION XI. THE ROTATION OF CROPS</h3> + +<p>Doubtless you know what is meant by rotation, for your teacher has +explained to you already how the earth rotates, or turns, on its axis +and revolves around the sun. When we speak of crop-rotation we mean not +only that the same crop should not be planted on the same land for two +successive years but that crops should follow one another in a regular +order.</p> + +<p>Many farmers do not follow a system of farming that involves a change of +crops. In some parts of the country the same fields are planted to corn +or wheat or cotton year after year. This is not a good practice and +sooner or later will wear out the soil completely, because the +soil-elements that furnish the food of that constant crop are soon +exhausted and good crop-production is no longer possible.</p> + +<p>Why is crop-rotation so necessary? There are different kinds of plant +food in the soil. If any one of these is used up, the soil of course +loses its power to feed plants properly. Now each crop uses more of some +of the different kinds of foods than others do, just as you like some +kinds of food better than others. But the crop cannot, as you can, learn +to use the kinds of food it does not like; it must use the kind that +nature fitted it to use. Not only do different crops feed upon different +soil foods, but they use different quantities of these foods.<span class='pagenum'><a name="Page_34" id="Page_34">[Pg 34]</a></span></p> + +<p>Now if a farmer plant the same crop in the same field each year, that +crop soon uses up all of the available plant food that it likes. Hence +the soil can no longer properly nourish the crop that has been year by +year robbing it. If that crop is to be successfully grown again on the +land, the exhausted element must be restored.</p> + +<div class="figcenter"> + <img src="images/img045.jpg" width="500" height="331" + alt="Fig. 25." /><br /> + <b><span class="smcap">Fig. 25. Grass following Corn</span></b> + </div> + +<p>This can be done in two ways: first, by finding out what element has +here been exhausted, and then restoring this element by means either of +commercial fertilizers or manure; second, by planting on the land crops +that feed on different food and that will allow or assist kind Mother +Nature "to repair her waste places." An illustration may help you to +remember this fact. Nitrogen is, as already explained, one of the +commonest plant foods. It may almost be called plant bread. The wheat +crop uses up a good deal of nitrogen. Suppose a field were planted in +wheat year after year. Most of the available nitrogen would be taken out +of the soil after<span class='pagenum'><a name="Page_35" id="Page_35">[Pg 35]</a></span> a while, and a new wheat crop, if planted on the +field, would not get enough of its proper food to yield a paying +harvest. This same land, however, that could not grow wheat could +produce other crops that do not require so much nitrogen. For example, +it could grow cowpeas. Cowpeas, aided by their root-tubercles, are able +to gather from the air a great part of the nitrogen needed for their +growth. Thus a good crop of peas can be obtained even if there is little +available nitrogen in the soil. On the other hand wheat and corn and +cotton cannot use the free nitrogen of the air, and they suffer if there +is an insufficient quantity present in the soil; hence the necessity of +growing legumes to supply what is lacking.</p> + +<div class="figcenter"> + <img src="images/img046.jpg" width="500" height="395" + alt="Fig. 26." /><br /> + <b><span class="smcap">Fig. 26.

Plow or disk the wheat stubble, and sow the same field +to cowpeas. If the wheat crop has exhausted the greater part of the +nitrogen of the soil, it makes no difference to the cowpea; for the +cowpea will get its nitrogen from the air and not only provide for its +own growth but will leave quantities of nitrogen in the queer nodules of +its roots for the crops coming after it in the rotation.</p> + +<div class="figcenter"> + <img src="images/img047.jpg" width="500" height="395" + alt="Fig. 27." /><br /> + <b><span class="smcap">Fig. 27. Cowpeas and Corn—October</span></b> + </div> + +<p>If corn be planted, there should be a rotation in just the same way. The +corn plant, a summer grower, of course uses a certain portion of the +plant food stored in the soil. In order that the crop following the corn +may feed on what the corn did not use, this crop should be one that +requires a somewhat different food. Moreover, it should be one that fits +in well with corn so as to make a winter crop. We find just<span class='pagenum'><a name="Page_37" id="Page_37">[Pg 37]</a></span> such a +plant in clover or wheat.

HOW A PLANT FEEDS FROM THE AIR</h3> + +<p>If you partly burn a match you will see that it becomes black. This +black substance into which the match changes is called <i>carbon</i>. Examine +a fresh stick of charcoal, which is, as you no doubt know, burnt wood. +You see in the charcoal every fiber that you saw in the wood itself. +This means that every part of the plant contains carbon. How important, +then, is this substance to the plant!</p> + +<p>You will be surprised to know that the total amount of carbon in plants +comes from the air. All the carbon that a plant gets is taken in by the +leaves of the plant; not a particle is gathered by the roots. A large +tree, weighing perhaps 11,000 pounds, requires in its growth carbon from +16,000,000 cubic yards of air.</p> + +<p>Perhaps, after these statements, you may think there is danger that the +carbon of the air may sometime become exhausted. The air of the whole +world contains about 1,760,000,000,000 pounds of carbon. Moreover, this +is continually being added to by our fires and by the breath of animals. +When wood or coal is used for fuel the carbon of the burning substance +is returned to the air in the form of gas. Some large factories burn +great quantities of coal and thus turn much carbon back to the air. A +single factory in Germany<span class='pagenum'><a name="Page_40" id="Page_40">[Pg 40]</a></span> is estimated to give back to the air daily +about 5,280,000 pounds of carbon. You see, then, that carbon is +constantly being put back into the air to replace that which is used by +growing plants.</p> + +<p>The carbon of the air can be used by none but green plants, and by them +only in the sunlight. We may compare the green coloring matter of the +leaf to a machine, and the sunlight to the power, or energy, which keeps +the machine in motion. By means, then, of sunlight and the green +coloring matter of the leaves, the plant secures carbon. The carbon +passes into the plant and is there made into two foods very necessary to +the plant; namely, starch and sugar.</p> + +<p>Sometimes the plant uses the starch and sugar immediately. At other +times it stores both away, as it does in the Irish and the sweet potato +and in beets, cabbage, peas, and beans. These plants are used as food by +man because they contain so much nourishment; that is, starch and sugar +which were stored away by the plant for its own future use.</p> + + +<div class="blockquot"><p style="margin-top: 2em;"><b>EXERCISE</b></p> + +<p>Examine some charcoal. Can you see the rings of growth? Slightly +char paper, cloth, meat, sugar, starch, etc. What does the turning +black prove? What per cent of these substances do you think is pure +carbon?</p></div> + + +<h3>SECTION XIII. THE SAP CURRENT</h3> + +<p>The root-hairs take nourishment from the soil. The leaves manufacture +starch and sugar. These manufactured foods must be carried to all parts +of the plant. There are two currents to carry them. One passes from the +roots through the young wood to the leaves, and one, a downward current, +passes through the bark, carrying needed food to the roots (see Fig. +28).<span class='pagenum'><a name="Page_41" id="Page_41">[Pg 41]</a></span></p> + + +<div class="figleft"> + <img src="images/img052a.jpg" width="68" height="200" + alt="Fig. 28." /><br /> + <b><span class="smcap">Fig. 28 Movement<br />of the Sap Current</span></b> + </div> +<p>If you should injure the roots, the water supply to the leaves would be +cut off and the leaves would immediately wither. On the other hand, if +you remove the bark, that is, girdle the tree, you in no way interfere +with the water supply and the leaves do not wither. Girdling does, +however, interfere with the downward food current through the bark.</p> + +<div class="figright"> + <img src="images/img052b.jpg" width="87" height="150" + alt="Fig. 29." /><br /> + <b><span class="smcap">Fig. 29.

Owing to this food stoppage the roots will +cease to grow and will soon be unable to take in sufficient water, and +then the leaves will begin to droop. This, however, may not happen until +several months after the girdling. Sometimes a partly girdled branch +grows much in thickness just above the girdle, as is shown in Fig. 29. +This extra growth seems to be due to a stoppage of the rich supply of +food which was on its way to the roots through the bark.

THE FLOWER AND THE SEED</h3> + + +<div class="figleft"> + <img src="images/img053.jpg" width="69" height="150" + alt="Fig. 30." /><br /> + <b><span class="smcap">Fig. 30.

Undoubtedly a flower is beautiful, and to be beautiful is one +of the uses of many flowers; but it is not the chief use of a flower.</p> + +<p>You know that when peach or apple blossoms are nipped by the spring +frost the fruit crop is in danger. The fruit of the plant bears the +seed, and the flower produces the fruit. That is its chief duty.</p> + + +<p>Do you know any plant that produces seed without flowers? Some one +answers, "The corn, the elm, and the maple all produce seed, but have no +flower." No, that is not correct. If you look closely you will find in +the spring very small flowers on the elm and on the maple, while the ear +and the tassel are really the blossoms of the corn plant. Every plant +that produces<span class='pagenum'><a name="Page_43" id="Page_43">[Pg 43]</a></span> seed has flowers, although they may sometimes seem very +curious flowers.</p> + +<div class="figcenter"> + <img src="images/img054a.jpg" width="400" height="187" + alt="Fig. 31." /><br /> + <b><span class="smcap">Fig. 31.

A Plum Blossom</span></b> + </div> +<p>Let us see what a flower really is. Take, for example, a buttercup, +cotton, tobacco, or plum blossom (see Figs. 31 and 32). You will find on +the outside a row of green leaves inclosing the flower when it is still +a bud. These leaves are the <i>sepals</i>. Next on the inside is a row of +colored leaves, or <i>petals</i>. Arranged inside of the petals are some +threadlike parts, each with a knob on the end. These are the <i>stamens</i>. +Examine one stamen closely (Fig. 33). On the knob at its tip you should +find, if the flower is fully open, some fine grains, or powder. In the +lily this powder is so abundant that in smelling the flower you often +brush a quantity of it off on your nose. This substance is called +<i>pollen</i>, and the knob on the end of the stamen, on which the pollen is +borne, is the <i>anther</i>.</p> + + +<p><span class='pagenum'><a name="Page_44" id="Page_44">[Pg 44]</a></span></p> + +<p>The pollen is of very great importance to the flower. Without it there +could be no seeds. The stamens as pollen-bearers, then, are very +important. But there is another part to each flower that is of equal +value. This part you will find in the center of the flower, inside the +circle of stamens. It is called the <i>pistil</i> (Fig. 32). The swollen tip +of the pistil is the <i>stigma</i>. The swollen base of the pistil forms the +<i>ovary</i>. If you carefully cut open this ovary you will find in it +very small immature seeds.</p> + +<div class="figleft"> + <img src="images/img055a.jpg" width="90" height="150" + alt="Fig. 33." /><br /> + <b><span class="smcap">Fig. 33.

A Tomato Blossom</span></b> + </div> +<p>Some plants bear all these parts in the same flower; that is, each +blossom has stamens, pistil, petals, and sepals. The pear blossom and +the tomato blossom represent such flowers. Other plants bear their +stamens and pistils in separate blossoms. Stamens and pistils may even +occur in separate plants, and some blossoms have no sepals or petals at +all. Look at the corn plant. Here the tassel is a cluster of many +flowers, each of which bears only stamens. The ear is likewise a cluster +of many flowers, each of which bears only a pistil. The dust that you +see falling from the tassel is the pollen, and the long silky threads of +the ear are the stigmas.</p> +<p><span class='pagenum'><a name="Page_45" id="Page_45">[Pg 45]</a></span></p> + +<p>Now no plant can bear seeds unless the pollen of the stamen falls on the +stigma. Corn cannot therefore form seed unless the dust of the tassel +falls upon the silk. Did you ever notice how poorly the cob is filled on +a single cornstalk standing alone in a field? Do you see why? It is +because when a plant stands alone the wind blows the pollen away from +the tassel, and little or none is received on the stigmas below.</p> + +<div class="figright"> + <img src="images/img056.jpg" width="300" height="180" + alt="Fig. 35." /><br /> + <b><span class="smcap">Fig. 35. Cucumber Blossoms</span></b> + </div> + +<p>In the corn plant the stamens and pistils are separate; that is, they do +not occur on the same flower, although they are on the same plant. This +is also true of the cucumber (see Fig. 35). In many plants, however, +such as the hemp, hop, sassafras, willow, and others, the staminate +parts are on one plant and the pistillate parts are on another. This is +also true in several other cultivated plants. For example, in some +strawberries the stamens are absent or useless; that is, they bear no +good pollen. In such cases the grower must see to it that near by are +strawberry plants that bear stamens, in order that those plants which do +not bear pollen may become <i>pollinated</i>; that is, may have pollen +carried to them. After the stigma has been supplied with pollen, a +single pollen grain sends a threadlike sprout down through the stigma +into the ovary. This process, if successfully completed, is called +<i>fertilization</i>.<span class='pagenum'><a name="Page_46" id="Page_46">[Pg 46]</a></span></p> + + +<div class="blockquot"><p style="margin-top: 2em;"><b>EXERCISE</b></p> + +<p>Examine several flowers and identify the parts named in the last +section.

Measure one +and watch it closely from day to day. Can you find any plants that +have their stamens and ovaries on separate individuals?</p></div> + + +<h3>SECTION XV. POLLINATION</h3> + +<p>Nature has several interesting ways of bringing about pollination. In +the corn, willow, and pine the pollen is picked up by the wind and +carried away. Much of it is lost, but some reaches the stigmas, or +receptive parts, of other corn, willow, or pine flowers. This is a very +wasteful method, and all plants using it must provide much pollen.</p> + +<p>Many plants employ a much better method. They have learned how to make +insects bear their pollen. In plants of this type the parts of the +blossom are so shaped and so placed as to deposit pollen from the stamen +on the insect and to receive pollen from the insect on the stigmas.</p> + +<p>When you see the clumsy bumblebee clambering over and pushing his way +into a clover blossom, you may be sure that he is getting well dusted +with pollen and that the next blossom which he visits will secure a full +share on its stigmas.</p> + +<p>When flowers fit themselves to be pollinated by insects they can no +longer use the wind and are helpless if insects do not visit them. They +therefore cunningly plan two ways to invite the visits of insects. +First, they provide a sweet nectar as a repast for the insect visitor. +The nectar is a sugary solution found in the bottom of the flower and is +used by the visitor as food or to make honey. Second, flowers advertise<span class='pagenum'><a name="Page_47" id="Page_47">[Pg 47]</a></span> +to let each insect know that they have something for it. The advertising +is done either by showy colors or by perfume. Insects have wonderful +powers of smell. When you see showy flowers or smell fragrant ones, you +will know that such flowers are advertising the presence either of +nectar or of pollen (to make beebread) and that such flowers depend on +insects for pollination.</p> + +<div class="figcenter"> + <img src="images/img058.jpg" width="400" height="363" + alt="Fig. 36." /><br /> + <b><span class="smcap">Fig. 36. Bees carrying Pollen</span></b> + </div> + +<p>A season of heavy, cold rains during blossoming-time may often injure +the fruit crop by preventing insects from carrying pollen from flower to +flower. You now also understand why plants often fail to produce seeds +indoors. Since they are shut in, they cannot receive proper insect +visits. Plants such as tomatoes or other garden fruits dependent upon +insect pollination must, if raised in the greenhouse where insects +cannot visit them, be pollinated by hand.<span class='pagenum'><a name="Page_48" id="Page_48">[Pg 48]</a></span></p> + + +<div class="blockquot"><p style="margin-top: 2em;"><b>EXERCISE</b></p> + +<p>Exclude insect visitors from some flower or flower cluster, for +example, clover, by covering with a paper bag, and see whether the +flower can produce seeds that are capable of growing. Compare as to +number and vitality the seeds of such a flower with those of an +uncovered flower. Observe insects closely. Do you ever find pollen +on them? What kinds of insects visit the clover? the cowpea? the +sourwood? the flax? Is wheat pollinated by insects or by the wind +or by some other means? Do bees fly in rainy weather? How will a +long rainy season at blossoming-time affect the apple crop? Why? +Should bees be kept in an orchard? Why?</p></div> + + +<h3>SECTION XVI. CROSSES, HYBRIDS, AND CROSS-POLLINATION</h3> + +<p>In our study of flowers and their pollination we have seen that the seed +is usually the descendant of two parents, or at least of two organs—one +the ovary, producing the seed; the other the pollen, which is necessary +to fertilize the ovary.</p> + +<p>It happens that sometimes the pollen of one blossom fertilizes the ovary +of its own flower, but more often the pollen from one plant fertilizes +the ovary of another plant. This latter method is called +<i>cross-pollination</i>. As a rule cross-pollination makes seed that will +produce a better plant than simple pollination would. Cross-pollination +by hand is often used by plant-breeders when, for purposes of +seed-selection, a specially strong plant is desired. The steps in hand +pollination are as follows: (1) remove the anthers before they open, to +prevent them from pollinating the stigma (the steps in this process are +illustrated in Figs. 37, 38-39); (2) cover the flower thus treated with +a paper bag to prevent stray pollen from getting on it (see Fig. 40); +(3) when the ovary is sufficiently developed, carry pollen to the stigma +by hand from the<span class='pagenum'><a name="Page_49" id="Page_49">[Pg 49]</a></span> anthers of another plant which you have selected to +furnish it, and rebag to keep out any stray pollen which might +accidentally get in; (4) collect the seeds when they are mature and +label them properly.</p> + +<p>Hand pollination has this advantage—you know both parents of your seed. +If pollination occur naturally you know the maternal but have no means +of judging the paternal parent. You can readily see, therefore, how hand +pollination enables you to secure seed derived from two well-behaved +parents.</p> + +<div class="figcenter"> + <img src="images/img060.jpg" width="270" height="400" + alt="Fig. 37." /><br /> + <b><span class="smcap">Fig. 37.</span><br />The bud on right at top is in proper condition for removal of anthers;<br /> +the anthers have been removed from the buds below</b> + </div> + +<p>Sometimes we can breed one kind of plant on another. The result of such +cross-breeding is known as a <i>hybrid</i>. In the animal kingdom the mule is +a common example of this cross-breeding. Plant hybrids were formerly +called mules also, but this suggestive term is almost out of use.</p> + + +<p>It is only when plants of two distinct kinds are crossed that the result +is called a hybrid; for example, a blackjack oak on a white oak, an +apple on a pear. If the parent plants are closely related, for example, +two kinds of apples, the resulting plant is known simply as a <i>cross</i>.</p> + +<p>Hybrids and crosses are valuable in that they usually differ from both +parents and yet combine some qualities of each.<span class='pagenum'><a name="Page_50" id="Page_50">[Pg 50]</a></span></p> + +<div class="figcenter"> + <img src="images/img061a.jpg" width="400" height="127" + alt="Fig. 38." /><br /> + <b><span class="smcap">Fig. 38.

PROPAGATION BY BUDS</h3> + +<p>It is the business of the farmer to make plants grow, or, as it is +generally called, to propagate plants. This he does in one of two ways: +by buds (that is, by small pieces cut from parent plants), or by seeds. +The chief aim in both methods should be to secure in the most convenient +manner the best-paying plants.</p> + +<p>Many plants are most easily and quickly propagated by buds; for example, +the grape, red raspberry, fig, and many others that we cultivate for the +flower only, such as the carnation, geranium, rose, and begonia.<span class='pagenum'><a name="Page_52" id="Page_52">[Pg 52]</a></span></p> + +<div class="figcenter"> + <img src="images/img063.jpg" width="316" height="500" + alt="Fig. 41." /><br /> + <b><span class="smcap">Fig. 41.</span></b> + </div> + + + +<h4>Brighton pollinated by 1, Salem; 2, Creveling; 3, Lindley; 4, Brighton; +5, Self-pollinated; 6, Nectar; 7, Jefferson; 8, Niagara</h4> +<p><span class='pagenum'><a name="Page_53" id="Page_53">[Pg 53]</a></span></p> + +<div class="figright"> + <img src="images/img064.jpg" width="192" height="200" + alt="Fig. 42." /><br /> + <b><span class="smcap">Fig. 42.

The greatest care must be exercised in order to +get a healthy cutting. If we take a cutting from a poor plant, what can +we expect but to grow a poor plant like the one from which our cutting +was taken? On the other hand, if a fine, strong, vigorous, fruitful +plant be selected, we shall expect to grow just such a fine, healthy, +fruitful plant.</p> + +<p>We expect the cutting to make exactly the same variety of plant as the +parent stock. We must therefore decide on the variety of berry, grape, +fig, carnation, or rose that we wish to propagate, and then look for the +strongest and most promising plants of this variety within our reach. +The utmost care will not produce a fine plant if we start from poor +stock.</p> + + + +<p>What qualities are most desirable in a plant from which cuttings are to +be taken? First, it should be productive, hardy, and suited to your +climate and your needs; second, it should be healthy. Do not take +cuttings from a diseased plant, since the cutting may carry the +disease.<span class='pagenum'><a name="Page_54" id="Page_54">[Pg 54]</a></span></p> + +<div class="figleft"> + <img src="images/img065a.jpg" width="80" height="150" + alt="Fig. 43." /><br /> + <b><span class="smcap">Fig. 43. Grape Cutting</span><br />Showing depth to<br />which cutting should<br />be planted</b> + </div> + +<p>Cuttings may be taken from various parts of the plant, sometimes even +from parts of the leaf, as in the begonia (Fig. 46). More often, +however, they are drawn from parts of the stem (Figs. 43-45). As to the +age of the twig from which the cutting is to be taken, Professor Bailey +says: "For most plants the proper age or maturity of wood for the making +of cuttings may be determined by giving the twig a quick bend; if it +snaps and hangs by the bark, it is in proper condition. If it bends +without breaking, it is too young and soft or too old. If it splinters, +it is too old and woody." Some plants, as the geranium (Fig. 42), +succeed best if the cuttings from which they are grown are taken from +soft, young parts of the plant; others, for example, the grape or rose, +do better when the cutting is made from more mature wood.</p> + +<div class="figright"> + <img src="images/img065b.jpg" width="89" height="150" + alt="Fig. 44." /><br /> + <b><span class="smcap">Fig. 44. Carnation Cutting</span></b> + </div> + + +<p>Cuttings may vary in size and may include one or more buds. After a +hardy, vigorous cutting is made, insert it about one half or one third +of its length in soil. A soil free from organic matter is much the best, +since in such soil the cuttings are much less liable to disease. A fine, +clean sand is commonly used by professional gardeners. When cuttings +have<span class='pagenum'><a name="Page_55" id="Page_55">[Pg 55]</a></span> rooted well—this may require a month or more—they may be +transplanted to larger pots.</p> + +<p>Sometimes, instead of cutting off a piece and rooting it, portions of +branches are made to root before they are separated from the parent +plant. This method is often followed, and is known as <i>layering</i>. It is +a simple process. Just bend the tip of a bough down and bury it in the +earth (see Fig. 47). The black raspberry forms layers naturally, but +gardeners often aid it by burying the over-hanging tips in the earth, so +that more tips may easily take root. Strawberries develop runners that +root themselves in a similar fashion.</p> + +<div class="figleft"> + <img src="images/img066.jpg" width="200" height="160" + alt="Fig. 45." /><br /> + <b><span class="smcap">Fig. 45. Rose Cutting</span></b> + </div> +<p>Grafts and buds are really cuttings which, instead of being buried in +sand to produce roots of their own, are set on the roots of other +plants.</p> + + +<p>Grafting and budding are practiced when these methods are more +convenient than cuttings or when the gardener thinks there is danger of +failure to get plants to take root as cuttings. Neither grafting nor +budding is, however, necessary for the raspberry or the grape, for these +propagate most readily from cuttings.</p> + +<p>It is often the case that a budded or grafted plant is more fruitful +than a plant on its own roots. In cases of this kind, of course, grafts +or buds are used.</p> + +<p>The white, or Irish, potato is usually propagated from pieces of the +potato itself.

This +method of propagation is therefore really a peculiar kind of cutting.</p> + + +<p>Since the eye is a bud and our potato plant for next year is to develop +from this bud, it is of much importance, as we have seen, to know +exactly what <i>kind</i> of plant our potato comes from. If the potato is +taken from a small plant that had but a few poor potatoes in the hill, +we may expect the bud to produce a similar plant and a correspondingly +poor crop. We must see to it, then, that our seed potatoes are drawn +from vines that were good producers, because new potato plants are like +the plants from which they were grown. Of course when our potatoes are +in the bin we cannot tell from what kind of plants they came. We must +therefore <i>select our seed potatoes in the field</i>. Seed potatoes should +always be selected from those hills that produce most bountifully. Be +assured that the increased yield will richly repay this care in +selecting. It matters not so much whether the seed potato be large or +small; it must, however, come from a hill bearing a large yield of fine +potatoes.</p> + +<div class="figleft"> + <img src="images/img067.jpg" width="150" height="148" + alt="Fig. 46." /><br /> + <b><span class="smcap">Fig. 46. <br />Begonia-Leaf Cutting</span></b> + </div> +<p>Sweet-potato plants are produced from shoots, or growing buds, taken +from the potato itself, so that in their case too the piece that we use +in propagating is a part of the original plant, and will therefore be +like it under similar conditions.

A large +potato may not produce a bountifully yielding plant. <i>It will produce a +plant like the one that produced it.</i> It may be that this one large +potato was the only one produced by the original plant. If so, the plant +that grows from it will tend to be similarly unproductive. Thus you see +the importance of <i>selecting in the field a plant that has exactly the +qualities desired in the new plant</i>.</p> + +<div class="figleft"> + <img src="images/img069.jpg" width="48" height="200" + alt="Fig. 48." /><br /> + <b><span class="smcap">Fig. 48. Currant Cutting</span></b> + </div> +<p>One of the main reasons why gardeners raise plants from buds instead of +from seeds is that the seed of many plants will not produce plants like +the parent. This failure to "come true," as it is called, is sometimes +of value, for it occasionally leads to improvement. For example, suppose +that a thousand apple or other fruit or flower seeds from plants usually +propagated by cuttings be planted; it may be that one out of<span class='pagenum'><a name="Page_58" id="Page_58">[Pg 58]</a></span> a thousand +or a million will be a very valuable plant. If a valuable plant be so +produced, it should be most carefully guarded, multiplied by cuttings or +grafts, and introduced far and wide. It is in this way that new +varieties of fruits and flowers are produced from time to time.</p> + +<p>Sometimes, too, a single bud on a tree will differ from the other buds +and will produce a branch different from the other branches. This is +known as <i>bud variation</i>. When there is thus developed a branch which +happens to be of a superior kind, it should be propagated by cuttings +just as you would propagate it if it had originated from a seed.</p> + + + + +<p>Mr. Gideon of Minnesota planted many apple seeds, and from them all +raised one tree that was very fruitful, finely flavored, and able to +withstand the cold Minnesota winter. This tree he multiplied by grafts +and named the Wealthy apple. It is said that in giving this one apple to +the world he benefited mankind to the value of more than one million +dollars. It will be well to watch for any valuable bud or seed variant +and never let a promising one be lost.

PLANT SEEDING</h3> + +<p>In propagating by seed, as in reproducing by buds, we select a portion +of the parent plant—for a seed is surely a part of the parent +plant—and place it in the ground. There is, however, one great +difference between a seed and a bud. The bud is really a piece of the +parent plant, but a piece of <i>one</i> plant only, while a seed comes from +the parts of two plants.<span class='pagenum'><a name="Page_60" id="Page_60">[Pg 60]</a></span></p> + +<p>You will understand this fully if you read carefully Sections XIV-XVI. +Since the seed is made of two plants, the plant that springs from a seed +is much more likely to differ from its mother plant, that is, from the +plant that produces the seed, than is a plant produced merely by buds. +In some cases plants "come true to seed" very accurately. In others they +vary greatly. For example, when we plant the seed of wheat, turnips, +rye, onions, tomatoes, tobacco, or cotton, we get plants that are in +most respects like the parent plant. On the other hand the seed of a +Crawford peach or a Baldwin apple or a Bartlett pear will not produce +plants like its parent, but will rather resemble its wild forefathers. +These seedlings, thus taking after their ancestors, are always far +inferior to our present cultivated forms. In such cases seeding is not +practicable, and we must resort to bud propagation of one sort or +another.</p> + +<p>While in a few plants like those just mentioned the seed does not "come +true," most plants, for example, cotton, tobacco, and others, do "come +true." When we plant King cotton we may expect to raise King cotton. +There will be, however, as every one knows, some or even considerable +variation in the field. Some plants, even in exactly the same soil, will +be better than the average, and some will be poorer. Now we see this +variation in the plants of our field, and we believe that the plant will +be in the main like its parent. What should we learn from this? Surely +that if we wish to produce sturdy, healthy, productive plants we must go +into our fields and <i>pick out just such plants to secure seed from as we +wish to produce another year</i>. If we wait until the seed is separated +from the plant that produced it before we select our cotton seed, we +shall be planting seed from poor as well as from good plants, and must +be content with a crop of just such stock<span class='pagenum'><a name="Page_61" id="Page_61">[Pg 61]</a></span> <span class='pagenum'><a name="Page_62" id="Page_62">[Pg 62]</a></span>as we have planted. By +selecting seed from the most productive plants <i>in the field</i> and by +repeating the selection each year, you can continually improve the breed +of the plant you are raising. In selecting seed for cotton you may +follow the plan suggested below for wheat.</p> + +<div class="figcenter"> + <img src="images/img074.jpg" width="356" height="550" + alt="Fig. 49. 50." /><br /> + <b><span class="smcap">Figs. 49 and 50. Chrysanthemums and Asparagus</span></b> + </div> + + +<p>The difference that you see between the wild and the cultivated +chrysanthemums and between the samples of asparagus shown in Figs. 49 +and 50 was brought about by just such continuous seed-selection from the +kind of plant wanted.</p> + +<div class="figcenter"> + <img src="images/img075.jpg" width="400" height="182" + alt="Fig. 51." /><br /> + <b><span class="smcap">Fig. 51. Two Varieties of Flax From One Parent +Stock</span></b> + </div> + + +<p>By the careful selection of seed from the longest flax plants the +increase in length shown in the accompanying figure was gained. The +selection of seed from those plants bearing the most seed, regardless of +the height of the plant, has produced flax like that to the right in the +illustration. These two kinds of flax are from the same parent stock, +but slight differences have been emphasized by continued seed-selection, +until we now have really two varieties of flax, one a heavy seed-bearer, +the other producing a long fiber.</p> + +<p>You can in a similar way improve your cotton or any other seed crop. +Sugar beets have been made by seed-selection to produce about double the +percentage of sugar that they did<span class='pagenum'><a name="Page_63" id="Page_63">[Pg 63]</a></span> a few years ago. Preparing and +tilling land costs too much in money and work to allow the land to be +planted with poor seed. When you are trying by seed-selection to +increase the yield of cotton, there are two principles that should be +borne in mind: first, seed should be chosen only from plants that bear +many well-filled bolls of long-staple cotton; second, seed should be +taken from no plant that does not by its healthy condition show +hardihood in resisting disease and drouth.</p> + +<p>The plan of choosing seeds from selected plants may be applied to wheat; +but it would of course be too time-consuming to select enough single +wheat plants to furnish all of the seed wheat for the next year. In this +case adopt the following plan: In Fig. 52 let <i>A</i> represent the total +size of your wheat field and let <i>B</i> represent a plat large enough to +furnish seed for the whole field. At harvest-time go into section <i>A</i> +and select the best plants you can find. Pick the heads of these and +thresh them by hand. The seed so obtained must be carefully saved for +your next sowing.</p> + +<div class="figright"> + <img src="images/img076.jpg" width="250" height="205" + alt="Fig. 52." /><br /> + <b>Fig. 52.</b> + </div> + + +<p>In the fall sow these selected seeds in area <i>B</i>. This area should +produce the best wheat. At the next harvest cull not from the whole +field but from the finest plants of plat <i>B</i>, and again save these as +seed for plat <i>B</i>. Use the unculled seed from plat <i>B</i> to sow your crop. +By following this plan continuously<span class='pagenum'><a name="Page_64" id="Page_64">[Pg 64]</a></span> you will every year have seed from +several generations of choice plants, and each year you will improve +your seed.</p> + +<p>It is of course advisable to move your seed plat <i>B</i> every year or two. +For the new plat select land that has recently been planted in legumes. +Always give this plat unwearying care.</p> + +<p>In the selection of plants from which to get seed, you must know what +kind of plants are really the best seed plants. First, <i>you must not +regard single heads or grains, but must select seed from the most +perfect plant</i>, looking at the plant as a whole and not at any single +part of it. A first consideration is yield. Select the plants that yield +best and are at the same time resistant to drouth, resistant to rust and +to winter, early to ripen, plump of grain, and nonshattering. What a +fine thing it would be to find even one plant free from rust in the +midst of a rusted field! It would mean a <i>rust-resistant plant</i>. Its +offspring also would probably be rust-resistant. If you should ever find +such a plant, be sure to save its seed and plant it in a plat by itself. +The next year again save seed from those plants least rusted. Possibly +you can develop a rust-proof race of wheat! Keep your eyes open.</p> + +<p>In England the average yield of wheat is thirty bushels an acre, in the +United States it is less than fifteen bushels! In some states the yield +is even less than nine bushels an acre. Let us select our seed with +care, as the English people do, and then we can increase our yield. By +careful seed-selection a plant-breeder in Minnesota increased the yield +of his wheat by one fourth. Think what it would mean if twenty-five per +cent were added to the world's supply of wheat at comparatively no cost; +that is, at the mere cost of careful seed-selection. This would mean an +addition to the world's income of about $500,000,000 each year. The +United States would get about one fifth of this profit.<span class='pagenum'><a name="Page_65" id="Page_65">[Pg 65]</a></span></p> + +<p>It often happens that a single plant in a crop of corn, cotton, or wheat +will be far superior to all others in the field. Such a plant deserves +special care. Do not use it merely as a seed plant, but carefully plant +its seeds apart and tend carefully. The following season select the best +of its offspring as favorites again. Repeat this selection and culture +for several years until you fix the variety. This is the way new +varieties are originated from plants propagated by seed.</p> + +<p>In 1862 Mr. Abraham Fultz of Pennsylvania, while passing through a field +of bearded wheat, found three heads of beardless, or bald, wheat. These +he sowed by themselves that year, and as they turned out specially +productive he continued to sow this new variety. Soon he had enough seed +to distribute over the country.

Think how many bushels of wheat have been added to +the world's annual supply by a few moments of intelligent observation +and action on the part of this one man! He saw his opportunity and used +it.

The Kind<br />of Ear to Select</span></b> + </div> +<p>If a farmer would raise good crops he must, as already stated, select +good seed. Many of the farmer's disappointments in the quantity and +quality of his crops—disappointments often thought to come from other +causes—are the result of planting poor seed.

They all look alike in every +way. Now, has it ever occurred to you to ask why all blackbirds are +black?

How many ears of corn do you find +on a stalk? One, two, sometimes three or four. You find two ears of corn +on a stalk because it is the nature of that particular stalk to produce +two ears. In the same way the nature of some stalks is to produce but +one ear, while it is the nature of others sometimes to produce two or +more.<span class='pagenum'><a name="Page_67" id="Page_67">[Pg 67]</a></span></p> + +<p>This resemblance of offspring to parent is known to scientists as +heredity, or as "like producing like."</p> + +<p>Some Southern corn-breeders take advantage of this law to improve their +corn crop. If a stalk can be made to produce two ears of corn just as +large as the single ear that most stalks bear, we shall get twice as +much corn from a field in which the "two-eared" variety is planted. In +the North and West the best varieties of corn have been selected to make +but one ear to the stalk.

The difference between a large and a small yield +may depend upon the kind of plants we raise, and the kind of plant in +turn is dependent upon the seeds that we sow.</p> + +<p>Two things are important in the selection of seeds—purity and vitality. +Seeds should be <i>pure</i>; that is, when sown<span class='pagenum'><a name="Page_73" id="Page_73">[Pg 73]</a></span> they should produce no other +plant than the one that we wish to raise. They should be able to grow. +The ability of a seed to grow is termed its <i>vitality</i>. Good seed should +be nearly or quite pure and should possess high vitality. The vitality +of seeds is expressed as a per cent; for example, if 97 seeds out of 100 +germinate, or sprout, the vitality is said to be 97. The older the seed +the less is its vitality, except in a few rare instances in which seeds +cannot germinate under two or three years.</p> + +<p>Cucumber seeds may show 90 per cent vitality when they are one year old, +75 per cent when two years old, and 70 per cent when three years +old—the per cent of vitality diminishing with increase of years. The +average length of life of the seeds of cultivated plants is short: for +example, the tomato lives four years; corn, two years; the onion, two +years; the radish, five years. The cucumber seed may retain life after +ten years; but the seeds of this plant too lose their vitality with an +increase in years.</p> + +<p>It is important when buying seeds to test them for purity and vitality. +Dealers who are not honest often sell old seeds, although they know that +seeds decrease in value with age. Sometimes, however, to cloak +dishonesty they mix some new seeds with the old, or bleach old and +yellow seeds in order to make them resemble fresh ones.</p> + +<p>It is important, therefore, that all seeds bought of dealers should be +thoroughly examined and tested; for if they do not grow, we not only pay +for that which is useless but we are also in great danger of producing +so few plants in our fields that we shall not get full use of the land, +and thus we may suffer a more serious loss than merely paying for a few +dead seeds. It will therefore be both interesting and profitable to +learn how to test the vitality of seeds.<span class='pagenum'><a name="Page_74" id="Page_74">[Pg 74]</a></span></p> + +<p>To test vitality plant one hundred seeds in a pot of earth or in damp +sand, or place them between moist pieces of flannel, and take care to +keep them moist and warm. Count those that germinate and thus determine +the percentage of vitality. Germinating between flannel is much quicker +than planting in earth. Care should be used to keep mice away from +germinating seeds.

It is, however, much more difficult to +find out whether the seeds are pure. You can of course easily +distinguish seeds that differ much from those you wish to plant, but +often certain weed seeds are so nearly like certain crop seeds as not to +be easily recognized by the eye. Thus the dodder or "love vine," which +so often ruins the clover crop, has seeds closely resembling clover +seeds. The chess, or cheat, has seeds so nearly like oats that only a +close observer can tell them apart. However, if you watch the seeds that +you buy, and study the appearance of crop seeds, you may become expert +in recognizing those that have no place in your planting.</p> + +<p>One case is reported in which a seed-dealer intentionally allowed an +impurity of 30 per cent to remain in the crop seeds, and this impurity +was mainly of weed seeds.

The only way to tell +whether such seeds have been killed is to test samples of them for +vitality.

In your attempt suppose you try the following +plan. In the fall take the seed of an apple—a crab-apple is good—and +keep it in a cool place during the winter. The simplest way to do this +is to bury it in damp sand. In the spring plant it in a rich, loose +soil.</p> + +<p>Great care must be taken of the young shoot as soon as it appears above +the ground. You want to make it grow as tall and as straight as possible +during this first year of its life, hence you should give it rich soil +and protect it from animals. Before the ground freezes in the fall take +up the young tree with the soil that was around it and keep it all +winter in a cool, damp place.</p> + +<p>Now when spring comes it will not do to set out the carefully tended +tree, for an apple tree from seed will not be a tree like its parent, +but will tend to resemble a more distant ancestor. The distant ancestor +that the young apple tree is most likely to take after is the wild +apple, which is small, sour, and otherwise far inferior to the fruit we +wish to grow. It makes little difference, therefore, what kind of apple +seed we plant, since in any event we cannot be sure that the tree grown +from it will bear fruit worth having unless we force it to do so.<span class='pagenum'><a name="Page_77" id="Page_77">[Pg 77]</a></span></p> + +<div class="figcenter"> + <img src="images/img090.jpg" width="383" height="550" + alt="Fig. 63." /><br /> + <b><span class="smcap">Fig. 63.

Many people raise fruit trees +directly from seed without grafting. Thus they often produce really +worthless trees. By grafting they would make sure not only of having +good trees rather than poor ones but also of having the particular kind +of fruit that they wish. Hence you must now graft your tree.</p> + +<p>First you must decide what variety of apple you want to grow on the +tree. The Magnum Bonum is a great favorite as a fall apple. The Winesap +is a good winter apple, while the Red Astrachan is a profitable early +apple, especially in the lowland of the coast region. The Northern Spy, +Æsop, and Spitzenburg are also admirable kinds. Possibly some other +apple that you know may suit your taste and needs better than any of +these varieties.</p> + +<div class="figright"> + <img src="images/img092a.jpg" width="103" height="180" + alt="Fig. 65." /><br /> + <b><span class="smcap">Fig. 65.

Choose a twig that is about the +thickness of the young tree at the point where you wish to graft. Be +careful to take the shoot from a vigorous, healthy part of the tree.</p> + + +<p>There are many ways in which you may join the chosen shoot or twig upon +the young tree, but perhaps the best<span class='pagenum'><a name="Page_79" id="Page_79">[Pg 79]</a></span> one for you to use is known as +<i>tongue grafting</i>. This is illustrated in Fig. 64. The upper part, <i>b</i>, +which is the shoot or twig that you cut from the tree, is known as the +<i>scion</i>; the lower part, <i>a</i>, which is the original tree, is called the +<i>stock</i>.</p> + + + + +<p>Cut the scion and stock as shown in Fig. 64. Join the cut end of the +scion to the cut end of the stock. When you join them, notice that under +the bark of each there is a thin layer of soft, juicy tissue. This is +called the <i>cambium</i>. To make a successful graft the cambium in the +scion must exactly join the cambium in the stock. Be careful, then, to +see that cambium meets cambium. You now see why grafting can be more +successfully done if you select a scion and stock of nearly the same +size.</p> + +<div class="figright"> + <img src="images/img092b.jpg" width="70" height="180" + alt="Fig. 66." /><br /> + <b><span class="smcap">Fig. 66.</span><br />To make a root<br /> graft, cut along<br /> the slanting line</b> + </div> + +<p>After fitting the parts closely together, bind them with cotton yarn +(see Fig. 65) that has been coated with grafting wax.

The slanting double +line in Fig. 66 shows the proper place to cut off for such grafting.</p> + + +<p>If you like you may sometime make the interesting and valuable +experiment of grafting scions from various kinds of apple trees on the +branches of one stock.

Just before using cut the bud from the scion, as +shown in Fig. 69. This bud is now ready to be inserted on the north side +of the stock, just two or three inches above the ground. The north side +is selected to avoid the sun. Now, as shown at <i>a</i> in Fig. 70, make a +cross and an up-and-down incision, or cut, on the stock; pull the bark +back carefully, as shown in <i>B</i>; insert the bud <i>C</i>, as shown in <i>D</i>; +then fold the bark back and wrap with yarn or raffia, as shown in <i>E</i>. +As soon as the bud and branches have united, remove the wrapping to +prevent its cutting the bark and cut the tree back close to the bud, as +in Fig. 71, so as to force nourishment into the inserted bud.</p> + + +<p>Budding is done in the field without disturbing the tree as it stands in +the ground. The best time to do budding is during the summer or fall +months, when the bark is loose enough to allow the buds to be easily +inserted.</p> + + + +<p>Trees may be budded or grafted on one another only when they are nearly +related. Thus the apple, crab-apple, hawthorn, and quince are all +related closely enough to graft or bud on one another; the pear grows on +some hawthorns, but not well on an apple; some chestnuts will unite with +some kinds of oaks.</p> + +<p>By using any of these methods you can succeed in getting with certainty +the kind of tree that you desire.</p> + +<div class="figcenter"> + <img src="images/img003.jpg" width="333" height="500" + alt="BOTH BUSY STORING APPLES" /><br /> + <b>BOTH BUSY STORING APPLES</b> + </div> + +<p><span class='pagenum'><a name="Page_83" id="Page_83">[Pg 83]</a></span></p> + + +<h3>SECTION XXIV.

The object of pruning is to give +the tree proper shape and to promote fruit-bearing. If the bud at the +end of the main shoot grows, you will have a tall, cone-shaped tree. If, +however, the end of the young tree be cut or "headed back" to the lines +shown in Fig. 72, the buds below this point will be forced to grow and +make a tree like that shown in Fig. 73. The proper height of heading for +different fruits varies. For the apple tree a height of two or three +feet is best.<span class='pagenum'><a name="Page_84" id="Page_84">[Pg 84]</a></span></p> + +<div class="figleft"> + <img src="images/img099a.jpg" width="225" height="250" + alt="Fig. 75." /><br /> + <b><span class="smcap">Fig. 75.</span><br />Unthinned</b> + </div> + +<div class="figright"> + <img src="images/img099b.jpg" width="223" height="250" + alt="Fig. 76." /><br /> + <b><span class="smcap">Fig. 76.</span><br />Properly thinned</b> + </div> + +<p>Cutting an end bud of a shoot or branch always sends the nourishment and +growth into the side buds. Trimming or pinching off the side buds throws +the growth into the end bud. You can therefore cause your tree to take +almost any shape you desire. The difference between the trees shown in +Figs. 73 and 74 is entirely the result of pruning. Fig. 74 illustrates +in general a correctly shaped tree. It is evenly balanced, admits light +freely, and yet has enough foliage to prevent sun-scald. Figs. 75 and 76 +show the effect of wisely thinning the branches.</p> + + +<p>The best time to prune is either in the winter or before the buds start +in the spring. Winter pruning tends to favor wood-production, while +summer pruning lessens wood-production and induces fruitage.</p> + + +<p>Each particular kind of fruit requires special pruning; for example, the +peach should be made to assume the shape illustrated in Fig. 77. This is +done by successive trimmings, following the plan illustrated in Figs. +71, 78, 79. You will gain several advantages from these trimmings. +First,<span class='pagenum'><a name="Page_85" id="Page_85">[Pg 85]</a></span> nourishment will be forced into the peach bud that you set on +your stock. This will secure a vigorous growth of the scion. By a second +trimming take off the "heel" (Fig. 78, <i>h</i>) close to the tree, and thus +prevent decay at this point. One year after budding you should reduce +the tree to a "whip," as in Fig. 79, by trimming at the dotted line in +Fig. 78. This establishes the "head" of the tree, which in the case of +the peach should be very low,—about sixteen inches from the ground,—in +order that a low foliage may lessen the danger of sun-scald to the main +trunk.</p> + +<div class="figleft"> + <img src="images/img100a.jpg" width="184" height="250" + alt="Fig. 77." /><br /> + <b><span class="smcap">Fig. 77.

MARKET-GARDENING</h3> + +<p>The word <i>horticulture</i> is one of those broad words under which much is +grouped. It includes the cultivation of orchard fruits, such as apples +and plums; of small fruits, such as strawberries and raspberries; of +garden vegetables for the table; of flowers of all sorts, including +shrubbery and ornamental trees and their arrangement into beautiful +landscape effects around our homes. Horticulture then is a name for an +art that is both far-reaching and important.</p> + +<p>The word <i>gardening</i> is generally given to that part of horticulture +which has for its chief aim the raising of vegetables for our tables.</p> + +<p>Flower-gardening, or the cultivation of plants valued for their bloom in +making ornamental beds and borders and furnishing flowers for the +decoration of the home, is generally called <i>floriculture</i>. +Landscape-gardening is the art of so arranging flower-beds, grass, +shrubbery, and trees as to produce pleasing effects in the grounds +surrounding our homes and in great public parks and pleasure grounds.</p> + +<p>Landscape-gardening, like architecture, has developed intoll as the +artist makes them on canvas, but uses natural objects in his pictures +instead of paint and canvas.<span class='pagenum'><a name="Page_90" id="Page_90">[Pg 90]</a></span></p> + +<p><b>Market-Gardening.</b> Formerly market-gardening was done on small tracts +of land in the immediate vicinity of large cities, where supplies of +stable manure could be used from the city stables. But with the great +increase in the population of the cities, these small areas could no +longer supply the demand, and the introduction of commercial fertilizers +and the building of railroads enabled gardeners at great distances from +city markets to grow and ship their products. Hence the markets, even in +winter, are now supplied with fresh vegetables from regions where there +is no frost. Then, as spring opens, fruits and vegetables are shipped +from more temperate regions. Later vegetables and fruits come from the +sections nearer the great cities. This gradual nearing of the supply +fields continues until the gardens near the cities can furnish what is +needed.</p> + +<div class="figcenter"> + <img src="images/img105.jpg" width="400" height="285" + alt="Fig. 82." /><br /> + <b><span class="smcap">Fig. 82. Strawberry-Growing is an Art</span></b> + </div> + +<p><span class='pagenum'><a name="Page_91" id="Page_91">[Pg 91]</a></span></p> + +<p>The market-gardeners around the great Northern cities, finding that +winter products were coming from the South and from warmer regions, +began to build hothouses and by means of steam and hot-water pipes to +make warm climates in these glass houses. Many acres of land in the +colder sections of the country are covered with heated glass houses, and +in them during the winter are produced fine crops of tomatoes, lettuce, +radishes, cauliflowers, eggplants, and other vegetables. The degree of +perfection which these attain in spite of having such artificial +culture, and their freshness as compared to the products brought from a +great distance, have made winter gardening under glass a very profitable +business. But it is a business that calls for the highest skill and the +closest attention.</p> + +<div class="figright"> + <img src="images/img106.jpg" width="350" height="326" + alt="Fig. 83." /><br /> + <b><span class="smcap">Fig. 83. Setting Plants in a Cold-Frame</span></b> + </div> + +<p>No garden, even for home use, is complete without some glass sashes, and +the garden will be all the more successful if there is a small heated +greenhouse for starting plants that are afterwards to be set in the +garden.</p> + +<p><b>Hotbeds.</b> If there is no greenhouse, a hotbed is an important help in +the garden. The bed is made by digging a pit two feet deep, seven feet +wide, and as long as necessary.<span class='pagenum'><a name="Page_92" id="Page_92">[Pg 92]</a></span></p> + +<div class="figleft"> + <img src="images/img107.jpg" width="295" height="400" + alt="Fig. 84." /><br /> + <b><span class="smcap">Fig. 84. The Gladiolus</span></b> + </div> +<p>The material for the hotbed is fresh horse manure mixed with leaves. +This is thrown into a heap to heat. As soon as steam is seen coming from +the heap the manure is turned over and piled again so that the outer +part is thrown inside. When the whole is uniformly heated and has been +turned two or three times, it is packed firmly into the pit already dug.</p> + +<p>A frame six feet wide, twelve inches high on the north side and eight +inches on the south side and as long as the bed is to be, is now made of +plank. This is set upon the heated manure, thus leaving six inches on +each side outside the frame. More manure is then banked all around it, +and three or four inches of fine light and rich soil are placed inside +the frame.</p> + + +<p>The frame is then covered with hotbed sashes six feet long and three +feet wide. These slide up and down on strips of wood let into the sides +of the frame. A thermometer is stuck into the soil and closely watched, +for there will be too much heat at first for sowing seed. When the heat +in the early morning is about 85°, seeds may be sowed. The<span class='pagenum'><a name="Page_93" id="Page_93">[Pg 93]</a></span> hotbed is +used for starting tomato plants, eggplants, cabbage plants, and other +vegetables that cannot stand exposure. It should be made about eight or +ten weeks before the tender plants can be set out in the locality. In +the South and Southwest it should be started earlier than in the North. +For growing the best tomato plants, and for such hardy plants as lettuce +and cabbage, it will be better to have cold-frames in addition to the +hotbed; these need not be more than two or three sashes.</p> + +<p><b>Cold-Frames.</b> A cold-frame is like the frame used for a hotbed, but it +is placed on well-manured soil in a sheltered spot. It is covered with +the same kind of sashes and is used for hardening the plants sowed in +the hotbed. The frame must be well banked with earth on the outside, and +the glass must be covered on cold nights with straw, mats, or old +carpets to keep out frost.</p> + +<div class="figcenter"> + <img src="images/img108.jpg" width="400" height="121" + alt="Fig. 85." /><br /> + <b><span class="smcap">Fig. 85. Frame to carry the Sash of a Hotbed or +Cold-Frame</span></b> + </div> + +<p><b>Care of Hotbed and Cold-Frame.</b> If the sun be allowed to shine brightly +on the glass of a cold-frame or hotbed, it will soon raise the +temperature in the hotbed to a point that will destroy the plants. It is +necessary, then, to pay close attention to the bed and, when the sun +shines, to slip the sashes down or raise them and place a block under +the upper end to allow the steam to pass off. The cold-frame also must +be aired when the sun shines, and the sashes must be gradually<span class='pagenum'><a name="Page_94" id="Page_94">[Pg 94]</a></span> slipped +down in mild weather. Finally, they may be removed entirely on sunshiny +days, so as to accustom the plants to the open air, but they must be +replaced at night. For a while before setting the plants in the open +gardens, leave the sashes off night and day.</p> + + +<div class="figcenter"> + <img src="images/img109.jpg" width="400" height="265" + alt="Fig. 86." /><br /> + <b><span class="smcap">Fig. 86. Greenhouse and Cold-Frames</span></b> + </div> + +<p>While the hotbed may be used for starting plants, it is much better and +more convenient to have a little greenhouse with fire heat for this +purpose. A little house with but four sashes on each side will be enough +to start a great many plants, and will also give room for some flowers +in pots. With such a house a student can learn to manage a more +extensive structure if he gives close attention to airing, watering, and +keeping out insects.</p> + +<p><b>Sowing.</b> The time for sowing the different kinds of seeds is an +important matter. Seeds vary greatly in their requirements. All need +three conditions—a proper degree of heat, moisture, and air. Some +seeds, like English peas, parsnips,<span class='pagenum'><a name="Page_95" id="Page_95">[Pg 95]</a></span> beets, and radishes, will germinate +and grow when the soil is still cool in the early spring, and peas will +stand quite a frost after they are up. Therefore we plant English peas +as early as the ground can be worked.</p> + +<p>But if we should plant seeds like corn, string (or snap) beans, +squashes, and other tender plants before the ground is warm enough, they +would decay.</p> + +<p>Seeds cannot germinate in soil that is perfectly dry, for there must be +moisture to swell them and to start growth. The oxygen of the air is +also necessary, and if seeds are buried so deeply that the air cannot +reach them, they will not grow, even if they are warm and moist.</p> + +<div class="figcenter"> + <img src="images/img110.jpg" width="500" height="212" + alt="Fig. 87." /><br /> + <b><span class="smcap">Fig. 87. Gathering and shipping Celery</span></b> + </div> + +<p>The depth of planting must vary with the character and size of the seed. +English peas may be covered six inches deep and will be all the better +for such covering, but if corn be covered so deep, it hardly gets above +the ground. In planting small seeds like those of the radish, cabbage, +turnip, lettuce, etc., a good rule is to cover them three times the +thickness of the seed.<span class='pagenum'><a name="Page_96" id="Page_96">[Pg 96]</a></span></p> + +<p>In sowing seeds when the ground is rather dry, it is a good plan, after +covering them, to tramp on the row so as to press the soil closely to +the seeds and to help it to retain moisture for germination, but do not +pack the soil if it is damp.</p> + +<p>In spring never dig or plow the garden while it is still wet, but always +wait until the soil is dry enough to crumble freely.</p> + +<p><b>What Crops to grow.</b> The crops to be raised will of course depend upon +each gardener's climate, surroundings, and markets. Sometimes it may pay +a grower, if his soil and climate are particularly suited to one crop, +to expend most of his time and energy on this crop; for example, in some +sections of New York, on potatoes; in parts of Michigan, on celery; in +Georgia, on watermelons; in western North Carolina, on cabbage. If +circumstances allow this sort of gardening, it has many advantages, for +of course it is much easier to acquire skill in growing one crop than in +growing many.</p> + +<div class="figleft"> + <img src="images/img111.jpg" width="400" height="319" + alt="Fig. 88." /><br /> + <b><span class="smcap">Fig. 88. A Large Yield of Cabbages</span></b> + </div> + +<p>On the other hand, it often happens that a gardener's situation requires +him to grow most of the crops known to gardening. Each gardener then +must be guided in his selection of crops by his surroundings.<span class='pagenum'><a name="Page_97" id="Page_97">[Pg 97]</a></span></p> + +<p><b>Care of Crops.</b> The gardener who wishes to attain the greatest success +in his art must do four things:</p> + +<p>First, he must make his land rich and keep it rich. Much of his success +depends on getting his crops on the market ahead of other growers. To do +this, his crops must grow rapidly, and crops grow rapidly only in rich +soil. Then, too, land conveniently situated for market-gardening is +nearly always costly. Hence the successful market-gardener must plan to +secure the largest possible yield from as small an area as is +practicable. The largest yield can of course be secured from the richest +land.</p> + +<p>Second, the gardener must cultivate his rich land most carefully and +economically. He crowds his land with products that must grow apace. +Therefore he, least of all growers, can afford to have any of his soil +go to feed weeds, to have his land wash, or to have his growing crops +suffer for lack of timely and wise cultivation. To cultivate his land +economically the gardener must use the best tools and machines and the +best methods of soil management.</p> + +<p>Third, to get the best results he must grow perfect vegetables. To do +this, he must add to good tillage a knowledge of the common plant +diseases and of the ways of insects and bacterial pests; he must know +how and when to spray, how and when to treat his seed, how and when to +poison, how and when to trap his insect foes and to destroy their +hiding-places.</p> + +<p>Fourth, not only must the gardener grow perfect vegetables, but he must +put them on the market in perfect condition and in attractive shape. Who +cares to buy wilted, bruised, spoiling vegetables? Gathering, bundling, +crating, and shipping are all to be watched carefully. Baskets should be +neat and attractive, crates clean and snug, barrels well packed and well +headed. Careful attention to all these details brings a rich return.<span class='pagenum'><a name="Page_98" id="Page_98">[Pg 98]</a></span></p> + +<p>Among the gardener's important crops are the following:</p> + +<p><b>Asparagus.</b> This is a hardy plant. Its seed may be sowed either early +in the spring or late in the fall. The seeds should be planted in rows. +If the plants are well cultivated during the spring and summer, they +will make vigorous roots for transplanting in the autumn.</p> + +<p>In the fall prepare a piece of land by breaking it unusually deep and by +manuring it heavily. After the land is thoroughly prepared, make in it +furrows for the asparagus roots. These furrows should be six inches deep +and three feet apart. Then remove the roots from the rows in which they +have been growing during the summer, and set them two feet apart in the +prepared furrows. Cover carefully at once.</p> + +<div class="figleft"> + <img src="images/img113.jpg" width="388" height="400" + alt="Fig. 89." /><br /> + <b><span class="smcap">Fig. 89. A Crate of Asparagus</span></b> + </div> + +<p>In the following spring the young shoots must be well cultivated. In +order to economize space, beets or lettuce may be grown between the +asparagus rows during this first season. With the coming of cold weather +the asparagus must again be freely manured and all dead tops cut off. +Some plants will be ready for market the second spring. If the bed is +kept free from weeds and well manured, it will increase in +productiveness from year to year.</p> + +<p><b>Beans.</b> The most generally planted beans are those known as string, or +snap, beans. Of the many varieties, all are sensitive to cold and hence +must not be planted until frost is over.<span class='pagenum'><a name="Page_99" id="Page_99">[Pg 99]</a></span></p> + +<p>Another widely grown kind of bean is the lima, or butter, bean. There +are two varieties of the lima bean. One is large and generally grows on +poles. This kind does best in the Northern states. The other is a small +bean and may be grown without poles. This kind is best suited to the +warmer climates of the Southern states.</p> + +<p><b>Cabbage.</b> In comparatively warm climates the first crop of cabbage is +generally grown in the following way. The seeds are sowed in beds in +September, and the plants grown from this sowing are in November +transplanted to ground laid off in sharp ridges. The young plants are +set on the south side of the ridges in order that they may be somewhat +protected from the cold of winter. As spring comes on, the ridge is +partly cut down at each working until the field is leveled, and +thereafter the cultivation should be level.</p> + +<div class="figright"> + <img src="images/img114.jpg" width="400" height="280" + alt="Fig. 90." /><br /> + <b><span class="smcap">Fig. 90. Cabbage ready for Shipment</span></b> + </div> + +<p>Early cabbages need heavy applications of manure. In the spring, nitrate +of soda applied in the rows is very helpful.</p> + +<p>Seeds for the crop following this early crop should be sowed in March. +Of course these seeds should be of a later variety than the first used. +The young plants should be transplanted as soon as they are large +enough. Early cabbages are set in rows three feet apart, the plants +eighteen inches apart in the row. As the later varieties grow larger +than the earlier ones, the plants should be set two feet apart in the +row.<span class='pagenum'><a name="Page_100" id="Page_100">[Pg 100]</a></span></p> + +<p>In growing late fall and winter cabbage the time of sowing varies with +the climate. For the Northern and middle states, seeding should be done +during the last of March and in April. South of a line passing west from +Virginia it is hard to carry cabbages through the heat of summer and get +them to head in the fall. However, if the seeds are sowed about the +first of August in rich and moist soil and the plants set in the same +sort of soil in September, large heads can be secured for the December +market.</p> + +<div class="figleft"> + <img src="images/img115.jpg" width="341" height="400" + alt="Fig. 91." /><br /> + <b><span class="smcap">Fig. 91. Celery trimmed, washed, and bunched</span></b> + </div> + +<p><b>Celery.</b> In the extreme northern part of our country, celery seeds are +often sowed in a greenhouse or hotbed. This is done in order to secure +plants early enough for summer blanching. This plan, however, suits only +very cool climates.</p> + +<p>In the middle states the seeds are usually sowed in a well-prepared bed +about April. The young plants are moved to other beds as soon as they +need room. Generally they are transplanted in July to rows prepared for +them. These should be four feet apart, and the plants should be set six +inches apart in the row. The celery bed should be carefully cultivated +during the summer. In the fall, hill the stalks up enough to keep them +erect. After the growing season is over dig them and set them in +trenches. The trenches should be as deep as the celery is tall, and +after the celery is put in them they should be covered with boards and +straw.<span class='pagenum'><a name="Page_101" id="Page_101">[Pg 101]</a></span></p> + +<p>In the more southern states, celery is usually grown in beds. The beds +are generally made six feet wide, and rows a foot apart are run +crosswise. The plants are set six inches apart, in September, and the +whole bed is earthed up as the season advances. Finally, when winter +comes the beds are covered with leaves or straw to prevent the plants +from freezing. The celery is dug and bunched for market at any time +during the winter.</p> + +<p>By means of cold-frames a profitable crop of spring celery may be +raised. Have the plants ready to go into the cold-frames late in October +or early in November. The soil in the frame should be made very deep. +The plants should make only a moderately rapid growth during the winter. +In the early spring they will grow rapidly and so crowd one another as +to blanch well. As celery grown in this way comes on the market at a +time when no other celery can be had, it commands a good price.</p> + +<p>In climates as warm as that of Florida, beds of celery can be raised in +this way without the protection of cold-frames. A slight freeze does not +hurt celery, but a long-continued freezing spell will destroy it.</p> + +<p>Some kinds of celery seem to turn white naturally. These are called +self-blanching kinds. Other kinds need to be banked with earth in order +to make the stalks whiten. This kind usually gives the best and crispest +stalks.</p> + +<p><b>Cucumbers and Cantaloupes.</b> Although cucumbers and cantaloupes are very +different plants, they are grown in precisely the same way. Some +gardeners plant them in hills. However, this is perhaps not the best +plan. It is better to lay the land off in furrows six feet apart. After +filling these with well-rotted stable manure, throw soil over them. Then +make the top flat and plant the seeds. After the plants are up thin them +out, leaving them a foot or more apart in the<span class='pagenum'><a name="Page_102" id="Page_102">[Pg 102]</a></span> rows. Cultivate regularly +and carefully until the vines cover the entire ground.</p> + +<div class="figleft"> + <img src="images/img117.jpg" width="250" height="189" + alt="Fig. 92." /><br /> + <b><span class="smcap">Fig. 92. Striped Cucumber Beetle and Larva</span><br />All magnified</b> + </div> + +<p>It is a good plan to sow cowpeas at the last working of cantaloupes, in +order to furnish some shade for the melons. As both cucumbers and +cantaloupes are easily hurt by cold, they should not be planted until +the soil is warm and all danger of frost is past.</p> + +<p>Cucumbers are always cut while they are green. They should never be +pulled from the vine, but should always be cut with a piece of the stem +attached. Cantaloupes should be gathered before they turn yellow and +should be ripened in the house.</p> + + +<p>In some sections of the country the little striped cucumber-beetle +attacks the melons and cucumbers as soon as they come up. These beetles +are very active, and if their attacks are not prevented they will +destroy the tender plants. Bone dust and tobacco dust applied just as +the plants appear above the ground will prevent these attacks. This +treatment not only keeps off the beetle, but also helps the growth of +the plants.</p> + +<p><b>Eggplants.</b> Eggplants are so tender that they cannot be transplanted +like tomatoes to cold-frames and gradually hardened to stand the cold +spring air. These plants, started in a warm place, must be kept there +until the soil to which<span class='pagenum'><a name="Page_103" id="Page_103">[Pg 103]</a></span> they are to be transplanted is well warmed by +the advance of spring. After the warm weather has fully set in, +transplant them to rich soil, setting them three feet apart each way. +This plant needs much manure. If large, perfect fruit is expected, the +ground can hardly be made too rich.</p> + +<p>Eggplants are subject to the same bacterial blight that is so +destructive to tomatoes. The only way to prevent this disease is to +plant in ground not lately used for tomatoes or potatoes.</p> + + +<div class="figcenter"> + <img src="images/img118.jpg" width="400" height="273" + alt="Fig. 93." /><br /> + <b><span class="smcap">Fig. 93. An Onion Harvest</span></b> + </div> + +<p><b>Onions.</b> The method of growing onions varies with the use to which it +is intended to put them. To make the early sorts, which are eaten green +in the spring, little onions called <i>sets</i> are planted. These are grown +from seeds sowed late in the spring. The seeds are sowed thickly in rows +in rather poor land. The object of selecting poor land is that the +growth of the sets may be slow. When the sets have reached the size of +small marbles, they are ready for the fall planting.</p> + +<p>In the South the sets may be planted in September. Plant them in rows in +rich and well-fertilized soil. They<span class='pagenum'><a name="Page_104" id="Page_104">[Pg 104]</a></span> will be ready for market in March +or April. In the more northerly states the sets are to be planted as +early as possible in the spring.</p> + +<p>To grow ripe onions the seeds must be sowed as early in the spring as +the ground can be worked. The plants are thinned to a stand of three +inches in the rows. As they grow, the soil is drawn away from them so +that the onions sit on top of the soil with only their roots in the +earth.</p> + +<div class="figcenter"> + <img src="images/img119.jpg" width="400" height="229" + alt="Fig. 94." /><br /> + <b><span class="smcap">Fig. 94.

As onions keep best +with their tops attached, do not remove these until it is time for +marketing.</p> + +<p><b>Peas.</b> The English pea is about the first vegetable of the season to be +planted. It may be planted as soon as the ground is in workable +condition. Peas are planted in rows, and it is a good plan to stretch +wire netting for them to climb on. However, where peas are extensively +cultivated they are allowed to fall on the ground.<span class='pagenum'><a name="Page_105" id="Page_105">[Pg 105]</a></span></p> + +<p>There are many sorts of peas, differing both in quality and in time of +production. The first to be planted are the extra-early varieties. These +are not so fine as the later, wrinkled sorts, but the seeds are less apt +to rot in cold ground. Following these, some of the fine, wrinkled sorts +are to be planted in regular succession. Peas do not need much manure +and do best in a light, warm soil.</p> + +<p><b>Tomatoes.</b> There is no vegetable grown that is more widely used than +the tomato. Whether fresh or canned it is a staple article of food that +can be served in many ways.</p> + +<p>By careful selection and breeding, the fruit of the tomato has in recent +years been much improved. There are now many varieties that produce +perfectly smooth and solid fruit, and the grower can hardly go amiss in +his selection of seeds if he bears his climate and his particular needs +in mind.</p> + +<p>Early tomatoes are started in the greenhouse or in the hotbed about ten +weeks before the time for setting the plants in the open ground. They +are transplanted to cold-frames as soon as they are large enough to +handle. This is done to harden the plants and to give them room to grow +strong before the final transplanting.</p> + +<p>In kitchen gardens tomatoes are planted in rows four feet apart with the +plants two feet apart in the rows. They are generally trained to stakes +with but one stalk to a stake. When there is plenty of space, however, +the plants are allowed to grow at will and to tumble on the ground. In +this way they bear large crops. During the winter the markets are +supplied with tomatoes either from tropical sections or from hothouses. +As those grown in the hothouses are superior in flavor to those shipped +from Florida and from the West Indies, and as they command good prices, +great quantities are grown in this way.<span class='pagenum'><a name="Page_106" id="Page_106">[Pg 106]</a></span></p> + +<p>In the South the bacterial blight which attacks the plants of this +family is a serious drawback to tomato culture. The only way to escape +this disease is to avoid planting tomatoes on land in which eggplants, +tomatoes, or potatoes have been blighted. Lime spread around the plants +seems to prevent the blight for one season on some soils.</p> + +<p>At the approach of frost in the fall, green tomatoes can easily be +preserved by wrapping them in paper. Gather them carefully and wrap each +separately. Pack them in boxes and store in a cellar that is close +enough to prevent the freezing of the fruit. A few days before the +tomatoes are wanted for the table unpack as many as are needed, remove +the paper, and allow them to ripen in a warm room.</p> + +<p>Tomatoes require a rich soil. Scattering a small quantity of nitrate of +soda around their roots promotes rapid growth.</p> + +<p><b>Watermelons.</b> As watermelons need more room than can usually be spared +in a garden, they are commonly grown as a field crop.</p> + +<p>A very light, sandy soil suits watermelons best. They can be grown on +very poor soil if a good supply of compost be placed in each hill. The +land for the melons should be laid off in about ten-foot checks; that +is, the furrows should cross one another at right angles about every ten +feet. A wide hole should be dug where the furrows cross, and into this +composted manure should be put.</p> + +<p>The best manure for watermelons is a compost of stable manure and +wood-mold from the forest. Pile the manure and wood-mold in alternate +layers for some time before the planting season. During the winter cut +through the pile several times until the two are thoroughly mixed and +finely pulverized. Be sure to keep the compost heap under shelter. +Compost will lose in value if it is exposed to rains.<span class='pagenum'><a name="Page_107" id="Page_107">[Pg 107]</a></span></p> + +<p>At planting-time, put two or three shovelfuls of this compost into each +of the prepared holes, and over the top of the manure scatter a handful +of any high-grade complete fertilizer. Then cover fertilizer and manure +with soil, and plant the seeds in this soil. In cultivating, plow both +ways of the checked rows and throw the earth toward the plants.</p> + +<p>Some growers pinch off the vines when they have grown about three feet +long. This is done to make them branch more freely, but the pinching is +not necessary.</p> + +<div class="figcenter"> + <img src="images/img122.jpg" width="400" height="224" + alt="Fig. 95." /><br /> + <b><span class="smcap">Fig. 95. Dewberries</span></b> + </div> +<p>A serious disease, the watermelon wilt, is rapidly spreading through +melon-growing sections. This disease is caused by germs in the soil, and +the germs are hard to kill. If the wilt should appear in your +neighborhood, do not allow any stable manure to be used on your melon +land, for the germs are easily scattered by means of stable manure. The +germs also cling to the seeds of diseased melons, and these seeds bear +the disease to other fields. If you treat melon seeds as you are +directed on page 135 to treat oat seeds, the germs on the seeds will be +destroyed. By crossing the watermelon on the citron melon, a watermelon +that is resistant to wilt has recently been developed and successfully +grown in soils in which wilt is present. The new melon, inferior in +flavor at first, is being improved from season to season and bids fair +to rival other melons in flavor.</p> + +<p><span class='pagenum'><a name="Page_108" id="Page_108">[Pg 108]</a></span></p> + + +<h3>SECTION XXVI.

Of these +small things perhaps none holds a position of greater importance in +country life than the adornment of the home, indoors and outdoors, with +flowers tastefully arranged. Their selection and planting furnish +pleasant recreation; their care is a pleasing employment; and each +little plant, as it sprouts and grows and develops, may become as much a +pet as creatures of the sister animal kingdom. A beautiful, well-kept +yard adds greatly to the pleasure and attractiveness of a country home. +If a beautiful yard and home give joy to the mere passer-by, how much +more must their beauty appeal to the owners. The decorating of the home +shows ambition, pride, and energy—important elements in a successful +life.</p> + +<p>Plant trees and shrubs in your yard and border your masses of<span class='pagenum'><a name="Page_109" id="Page_109">[Pg 109]</a></span> + + shrubbery +with flower-beds. Do not disfigure a lawn by placing a bed of flowers in +it. Use the flowers rather to decorate the shrubbery, and for borders +along walks, and in the corners near steps, or against foundations.</p> + + + +<p>If you wish to raise flowers for the sake of flowers, not as +decorations, make the flower-beds in the back yard or at the side of the +house.</p> + + +<p>Plants may be grown from seeds or from bulbs or from cuttings. The +rooting of cuttings is an interesting task to all who are fond of +flowers. Those who have no greenhouse and who wish to root cuttings of +geraniums, roses, and other plants may do so in the following way. Take +a shallow pan, an old-fashioned milk pan for instance, fill it nearly +full of clean sand, and then wet the sand thoroughly. Stick the cuttings +thickly into this wet sand, set the pan in a warm, sunny window, and +keep the sand in the same water-soaked condition. Most cuttings will +root well in a few weeks and may then be set into small flower-pots. +Cuttings of tea roses should have two<span class='pagenum'><a name="Page_110" id="Page_110">[Pg 110]</a></span> or three joints and be taken from +a stem that has just made a flower. Allow one of the rose leaves to +remain at the top of the cutting. Stick this cutting into the sand and +it will root in about four weeks. Cuttings of Cape jasmine may be rooted +in the same way. Some geraniums, the rose geranium for example, may be +grown from cuttings of the roots.</p> + +<div class="figcenter"> + <img src="images/img125.jpg" width="400" height="302" + alt="Fig. 98." /><br /> + <b><span class="smcap">Fig. 98.

A Clematis</span></b> + </div> +<p>Bulbs are simply the lower ends of the leaves of a plant wrapped tightly +around one another and inclosing the bud that makes the future +flower-stalk. The hyacinth, the narcissus, and the common garden onion +are examples of bulbous plants. The flat part at the bottom of the bulb +is the stem of the plant reduced to a flat disk, and between each two +adjacent leaves on this flat stem there is a bud, just as above-ground +there is a bud at the base of a leaf. These buds on the stem of the bulb +rarely grow, however, unless forced to<span class='pagenum'><a name="Page_111" id="Page_111">[Pg 111]</a></span> do so artificially. The number +of bulbs may be greatly increased by making these buds grow and form +other bulbs. In increasing hyacinths the matured bulbs are dug in the +spring, and the under part of the flat stem is carefully scraped away to +expose the base of the buds. The bulbs are then put in heaps and covered +with sand. In a few weeks each bud has formed a little bulb. The +gardener plants the whole together to grow one season, after which the +little bulbs are separated and grown into full-sized bulbs for sale. +Other bulbs, like the narcissus or the daffodil, form new bulbs that +separate without being scraped.</p> + + + +<p>There are some other plants which have underground parts that are +commonly called bulbs but which are not bulbs at all; for example, the +gladiolus and the caladium, or elephant's ear. Their underground parts +are bulblike in shape, but are really solid flattened stems with eyes +like the underground stem of the Irish potato. These parts are called +<i>corms</i>. They may be cut into pieces like the potato and each part will +grow.</p> + +<p>The dahlia makes a mass of roots that look greatly like sweet potatoes, +but there are no eyes on them as there are on the sweet potato. The only +eyes are on the base of the<span class='pagenum'><a name="Page_112" id="Page_112">[Pg 112]</a></span> stem to which they are joined. They may be +sprouted like sweet potatoes and then soft cuttings made of the green +shoots, after which they may be rooted in the greenhouse and later +planted in pots.</p> + +<p>There are many perennial plants that will bloom the first season when +grown from the seed, though such seedlings are seldom so good as the +plants from which they came. They are generally used to originate new +varieties. Seeds of the dahlia, for instance, can be sowed in a box in a +warm room in early March, potted as soon as the plants are large enough +to handle, and finally planted in the garden when the weather is warm. +They will bloom nearly as soon as plants grown by dividing the roots or +from cuttings.</p> + +<div class="figcenter"> + <img src="images/img127.jpg" width="400" height="151" + alt="Fig. 100." /><br /> + <b><span class="smcap">Fig. 100.

Fine black forest mold, thoroughly +mixed with one fourth its bulk of well-rotted<span class='pagenum'><a name="Page_113" id="Page_113">[Pg 113]</a></span> manure, makes the best +soil for filling the seed-boxes. If this soil be placed in an oven and +heated very hot, the heat will destroy many weeds that would otherwise +give trouble. After the soil is put in the boxes it should be well +packed by pressing it with a flat wooden block. Sow the seeds in +straight rows, and at the ends of the rows put little wooden labels with +the names of the flowers on them.</p> + +<div class="figleft"> + <img src="images/img129.jpg" width="135" height="350" + alt="Fig. 102." /><br /> + <b><span class="smcap">Fig. 102. The Poet's Narcissus</span></b> + </div> +<p>Seeds sowed in the same box should be of the same general size in order +that they may be properly covered, for seeds need to be covered +according to their size. After sowing the seed, sift the fine soil over +the surface of the box. The best soil for covering small seeds is made +by rubbing dry moss and leaf-mold through a sieve together. This makes a +light cover that will not bake and will retain moisture. After covering +the seeds, press the soil firm and smooth with a wooden block. Now +sprinkle the covering soil lightly with a watering-pot until it is +fairly moistened. Lay some panes of glass over the box to retain the +moisture, and avoid further watering until moisture becomes absolutely +necessary.

The seeds should be sowed rather thickly in +rows and covered fully four inches<span class='pagenum'><a name="Page_115" id="Page_115">[Pg 115]</a></span> deep. The sowing should be varied in +time according to the climate. From North Carolina southward, sweet peas +may be sowed in the fall or in January, as they are very hardy and +should be forced to bloom before the weather becomes hot. Late spring +sowing will not give fine flowers in the South. From North Carolina +northward the seeds should be sowed just as early in the spring as the +ground can be easily worked. When the plants appear, stakes should be +set along the rows and a strip of woven-wire fence stretched for the +plants to climb on. Morning-glory seeds are also sowed where they are to +grow. The seeds of the moonflower are large and hard and will fail to +grow unless they are slightly cut. To start their growth make a slight +cut just through the hard outer coat of the seed so as to expose<span class='pagenum'><a name="Page_116" id="Page_116">[Pg 116]</a></span> the +white inside. In this way they will grow very readily. The seeds of the +canna, or Indian-shot plant, are treated in a similar way to start them +growing.</p> + +<div class="figleft"> + <img src="images/img131.jpg" width="255" height="350" + alt="Fig. 105." /><br /> + <b><span class="smcap">Fig. 105.

If allowed to get too dry, they will wither. From +central North Carolina south it is best to cover them up thickly with +dead leaves and let them stay in the ground where they grew. In the +early spring take them up and divide for replanting.</p> + +<p>Perennial plants, such as our flowering shrubs, are grown from cuttings +of the ripe wood after the leaves have fallen in autumn. From North +Carolina southward these cuttings should be set in rows in the fall. +Cuttings ten inches long are set so that the tops are just even with the +ground. A light cover of pine leaves will prevent damage from frost. +Farther north the cuttings should be tied in bundles and well buried in +the ground with earth heaped over them. In the spring set them in rows +for rooting. In the South all the hardy hybrid perpetual roses can be +grown<span class='pagenum'><a name="Page_117" id="Page_117">[Pg 117]</a></span> in this way, and in any section the cuttings of most of the +spring-flowering shrubs will grow in the same manner.

THE CAUSE AND NATURE OF PLANT DISEASE</h3> + +<p>Plants have diseases just as animals do; not the same diseases, to be +sure, but just as serious for the plant. Some of them are so dangerous +that they kill the plant; others partly or wholly destroy its usefulness +or its beauty. Some diseases are found oftenest on very young plants, +others prey on the middle-aged tree, while still others attack merely +the fruit. Whenever a farmer or fruit-grower has disease on his plants, +he is sure to lose much profit.</p> + +<p>You have all seen rotten fruit. This is diseased fruit. Fruit rot is a +plant disease. It costs farmers millions of dollars annually. A +fruit-grower recently lost sixty carloads of peaches in a single year +through rot which could have been largely prevented if he had known how.</p> + +<div class="figright"> + <img src="images/img140.jpg" width="300" height="244" + alt="Fig. 112." /><br /> + <b><span class="smcap">Fig. 112. Tangled Threads of Blue Mold</span></b> + </div> + +<p>Many of the yellowish or discolored spots on leaves are the result of +disease, as is also the smut of wheat, corn, and oats, the blight of the +pear, and the wilt of cotton. Many of these diseases are contagious, or, +as we often hear said of measles, "catching." This is true, among +others, of the apple and peach rots. A healthy apple can catch this +disease from a sick apple. You often see evidence of this in the apple +bin. So, too, many of the diseases found in the field or garden are +contagious.<span class='pagenum'><a name="Page_123" id="Page_123">[Pg 123]</a></span></p> + +<p>Sometimes when the skin of a rotten apple has been broken you will find +in the broken place a blue mold. It was this that caused the apple to +decay. This mold is a living plant; very small, certainly, but +nevertheless a plant. Let us learn a little about molds, in order that +we may better understand our apple and potato rots, as well as other +plant diseases.</p> + + + +<p>If you cut a lemon and let it stand for a day or two, there will +probably appear a blue mold like that you have seen on the surface of +canned fruit. Bread also sometimes has this blue mold; at other times +bread has a black mold, and yet again a pink or a yellow mold.</p> + +<p>These and all other molds are tiny living plants. Instead of seeds they +produce many very small bodies that serve the purpose of seeds and +reproduce the mold. These are called <i>spores</i>. Fig. 112 shows how they +are borne on the parent plant.</p> + +<div class="figleft"> + <img src="images/img141a.jpg" width="200" height="167" + alt="Fig. 113." /><br /> + <b><span class="smcap">Fig. 113.

A Mildewed Rose</span></b> + </div> +<p>It is also of great importance to decide whether by keeping the spores +away we may prevent mold. Possibly this experiment will help us. Moisten +a piece of bread, then dip a match or a pin into the blue mold on a +lemon, and draw the match across the moist bread. You will thus plant +the spores in a row, though they are so small that perhaps you may not +see any of them. Place the bread in a damp place<span class='pagenum'><a name="Page_124" id="Page_124">[Pg 124]</a></span> for a few days and +watch it. Does the mold grow where you planted it? Does it grow +elsewhere? This experiment should prove to you that molds are living +things and can be planted. If you find spots elsewhere, you must bear in +mind that these spores are very small and light and that some of them +were probably blown about when you made your sowing. When you touch the +moldy portion of a dry lemon, you see a cloud of dust rise. This dust is +made of millions of spores.</p> + + +<p>If you plant many other kinds of mold you will find that the molds come +true to the kind that is planted; that like produces like even among +molds.</p> + + +<p>You can prove, also, that the mold is caused only by other mold.

Some of them do him great injury, while +others aid him very much.<span class='pagenum'><a name="Page_128" id="Page_128">[Pg 128]</a></span></p> + +<p>You will see their importance when you are told that certain of them in +their habits of life cause great change in the substances in which they +live. For example, when living in a sugary substance they change the +sugar into a gas and an alcohol. Do you remember the bright bubbles of +gas you have seen rising in sweet cider or in wine as it soured? These +bubbles are caused by one of these small plants—the yeast plant. As the +yeast plant grows in the sweet fruit juice, alcohol is made and a gas is +given off at the same time, and this gas makes the bubbles.</p> + +<div class="figleft"> + <img src="images/img145.jpg" width="200" height="146" + alt="Fig. 117." /><br /> + <b><span class="smcap">Fig. 117.

Thus vinegar is made by the action of two +different kinds of little living plants in the cider. That these are +living beings you can prove by heating the cider and keeping it tightly +sealed so that nothing can enter it. You will find that because the +living germs have been killed by the heat, the cider will not ferment or +sour as it did before. The germs could of course be killed by poisons, +but then the cider would be unfit for use. It is this same little yeast +plant that causes bread to rise.</p> + +<p>When you see any decaying matter you may know that in it minute plants +much like the yeast plant are at work. Since decay is due to them, we +take advantage of the fact that they cannot grow in strong brine or +smoke; and we prepare meat for keeping by salting it or by smoking it or +by both of these methods.<span class='pagenum'><a name="Page_129" id="Page_129">[Pg 129]</a></span></p> +<div class="figright"> + <img src="images/img146.jpg" width="200" height="67" + alt="Fig. 118." /><br /> + <b><span class="smcap">Fig. 118.

When they do so they may produce disease. Typhoid fever, +diphtheria, consumption, and many other serious diseases are caused by +bacteria. Fig. 118, <i>e</i>, shows the bacterium that causes typhoid fever. +In the picture, of course, it is very greatly magnified.

PREVENTION OF PLANT DISEASE</h3> + +<p>In the last two sections you have learned something of the nature of +those fungi and bacteria that cause disease in animals and plants. Now +let us see how we can use this knowledge to lessen the diseases of our +crops. Farmers lose through plant diseases much that could be saved by +proper precaution.<span class='pagenum'><a name="Page_130" id="Page_130">[Pg 130]</a></span></p> + +<p>First, you must remember that every diseased fruit, twig, or leaf bears +millions of spores. These must be destroyed by burning. They must not be +allowed to lie about and spread the disease in the spring. See that +decayed fruit in the bin or on the trees is destroyed in the same +manner. Never throw decayed fruit into the garden or orchard, as it may +cause disease the following year.</p> + +<p>Second, you can often kill spores on seeds before they are planted and +thus prevent the development of the fungus (see pp. <a href='#Page_134'><b>134-137</b></a>).</p> + +<p>Third, often the foliage of the plant can be sprayed with a poison that +will prevent the germination of the spores (see pp. <a href='#Page_138'><b>138-140</b></a>).</p> + +<p>Fourth, some varieties of plants resist disease much more stoutly than +others. We may often select the resistant form to great advantage (see +Fig. 119).</p> + +<p>Fifth, after big limbs are pruned off, decay often sets in at the wound. +This decay may be prevented by coating the cut surface with paint, tar, +or some other substance that will not allow spores to enter the wound or +to germinate there.</p> + +<p>Sixth, it frequently happens that the spore or fungus remains in the +soil. This is true in the cotton wilt, and the remedy is so to rotate +crops that the diseased land is not used again for this crop until the +spores or fungi have died.</p> + + +<h3>SECTION XXX. SOME SPECIAL PLANT DISEASES</h3> + +<p><b>Fire-Blight of the Pear and Apple.</b> You have perhaps heard your father +speak of the "fire-blight" of pear and apple trees. This is one of the +most injurious and most widely known of fruit diseases. Do you want to +know the cause of this disease and how to prevent it?<span class='pagenum'><a name="Page_131" id="Page_131">[Pg 131]</a></span></p> + +<p>First, how will you recognize this disease? If the diseased bough at +which you are looking has true fire-blight, you will see a blackened +twig with withered, blackened leaves. During winter the leaves do not +fall from blighted twigs as they do from healthy ones. The leaves wither +because of the diseased twig, not because they are themselves diseased. +Only rarely does the blight really enter the leaf. Sometimes a sharp +line separates the blighted from the healthy part of the twig.</p> + +<p>This disease is caused by bacteria, of which you have read in another +section. The fire-blight bacteria grow in the juicy part of the stem, +between the wood and the bark. This tender, fresh layer (as explained on +page 79) is called the <i>cambium</i>, and is the part that breaks away and +allows you to slip the bark off when you make your bark whistle in the +spring. The growth of new wood takes place in the cambium, and this part +of the twig is therefore full of nourishment. If this nourishment is +stolen the plant of course soon suffers.</p> + +<p>The bacteria causing fire-blight are readily carried from flower to +flower and from twig to twig by insects; therefore to keep these and +other bacteria away from your trees you must see to it that all the +trees in the neighborhood of your orchard are kept free from mischievous +enemies. If harmful bacteria exist in near-by trees, insects will carry +them to your orchard. You must therefore watch all the relatives of the +pear; namely, the apple, hawthorn, crab, quince, and mountain ash, for +any of these trees may harbor the germs.</p> + +<div class="figcenter"> + <img src="images/img149.jpg" width="500" height="320" + alt="Fig. 119." /><br /> + <b><span class="smcap">Fig. 119.

Fire-Blight <br />Bacteria</span>Magnified</b> + </div> +<p>When any tree shows blight, every diseased twig on it must be cut off +and burned in order to kill the germs, and you must cut low enough on +the twig to get all the bacteria. It is best to cut a foot below the +blackened portion. If by chance your knife should cut into wood +containing the living<span class='pagenum'><a name="Page_133" id="Page_133">[Pg 133]</a></span><span class='pagenum'><a name="Page_132" id="Page_132">[Pg 132]</a></span> germs, and then you should cut into healthy wood +with the same knife, you yourself would spread the disease. It is +therefore best after each cutting to dip your knife into a solution of +carbolic acid. This will kill all bacteria clinging to the knife-blade. +The surest time to do complete trimming is after the leaves fall in the +autumn, as diseased twigs are most easily recognized at that time, but +the orchard should be carefully watched in the spring also. If a large +limb shows the blight, it is perhaps best to cut the tree entirely down. +There is little hope for such a tree.</p> + +<p>A large pear-grower once said that no man with a sharp knife need fear +the fire-blight. Yet our country loses greatly by this disease each +year.</p> + + + +<p>It may be added that winter pruning tends to make the tree form much new +wood and thus favors the disease. Rich soil and fertilizers make it much +easier in a similar way for the tree to become a prey to blight.</p> + + +<div class="blockquot"><p style="margin-top: 2em;"><b>EXERCISE</b></p> + +<p>Ask your teacher to show you a case of fire-blight on a pear or +apple tree. Can you distinguish between healthy and diseased wood? +Cut the twig open lengthwise and see how deep into the wood and how +far down the stem the disease extends. Can you tell surely from the +outside how far the twig is diseased? Can you find any twig that +does not show a distinct line of separation between diseased and +healthy wood? If so, the bacteria are still living in the cambium. +Cut out a small bit of the diseased portion and insert it under the +bark of a healthy, juicy twig within a few inches of its tip and +watch it from day to day. Does the<span class='pagenum'><a name="Page_134" id="Page_134">[Pg 134]</a></span> tree catch the disease? This +experiment may prove to you how easily the disease spreads. If you +should see any drops like dew hanging from diseased twigs, touch a +little of this moisture to a healthy flower and watch for results.</p> + +<p>Cut and burn all diseased twigs that you can find. Estimate the +damage done by fire-blight.</p> + +<p>Farmers' bulletins on orchard enemies are published by the +Department of Agriculture, Washington, D.C., and can be had by +writing for them. They will help your father much in treating +fire-blight.</p></div> + + +<p><b>Oat Smuts.</b> Let us go out into a near-by oat field and look for all the +blackened heads of grain that we can find. How many are there? To count +accurately let us select an area one foot square. We must look +carefully, for many of these blackened heads are so low that we shall +not see them at the first glance. You will be surprised to find as many +as thirty or forty heads in every hundred so blackened. These blackened +heads are due to a plant disease called <i>smut</i>.</p> + +<div class="figleft"> + <img src="images/img151.jpg" width="99" height="200" + alt="Fig. 121." /><br /> + <b><span class="smcap">Fig. 121.

When the beetle is at rest its two hard wings meet in a straight +line down the back. This peculiarity distinguishes it from the true bug, +which has four wings. The two outer wings are partly horny, and in +folding lap over each other. Butterflies and moths are much alike in +appearance but differ in habit. The butterfly works by day and the moth +by night.

First comes the egg. +The egg hatches into a worm-like animal known as a grub, maggot, or +caterpillar, or, as scientists call it, a <i>larva</i>. This creature feeds +and grows until finally it settles down and spins a home of silk, called +a <i>cocoon</i> (Fig. 145). If we open the cocoon we shall find that the +animal is now covered with a hard outside skeleton, that it cannot move +freely, and that it cannot eat at all. The animal in this state is known +as the <i>pupa</i> (Figs. 145 and 146). Sometimes, however, the pupa is not +covered by a cocoon, sometimes it is soft, and sometimes it has some +power of motion (Fig. 141). After a rest in the pupa stage the animal +comes out a mature insect (Figs. 142 and 143).<span class='pagenum'><a name="Page_148" id="Page_148">[Pg 148]</a></span></p> + +<p>From this you can see that it is especially important to know all you +can about the life of injurious insects, since it is often easier to +kill these pests at one stage of their life than at another.

Their +number therefore makes them a foe to be much dreaded. The queen honeybee +often lays as many as 4000 eggs in twenty-four hours. A single house fly +lays between 100 and 150 eggs in one day. The mosquito lays eggs in +quantities of from 200 to 400. The white ant often lays 80,000 in a day, +and so continues for two years, probably laying no less than 40,000,000 +eggs.

ORCHARD INSECTS</h3> + + +<p><b>The San Jose Scale.</b> The San Jose scale is one of the most dreaded +enemies of fruit trees. It is in fact an outlaw in many states. It is an +unlawful act to sell fruit trees affected by it. Fig. 150 shows a view +of a branch nearly covered with this pest. Although this scale is a very +minute animal, yet<span class='pagenum'><a name="Page_153" id="Page_153">[Pg 153]</a></span> so rapidly does it multiply that it is very +dangerous to the tree. Never allow new trees to be brought into your +orchard until you feel certain that they are free from the San Jose +scale. If, however, it should in any way gain access to your orchard, +you can prevent its spreading by thorough spraying with what is known as +the lime-sulphur mixture. This mixture has long been used on the Pacific +coast as a remedy for various scale insects. When it was first tried in +other parts of the United States the results were not satisfactory and +its use was abandoned. However, later experiments with it have proved +that the mixture is thoroughly effective in killing this scale and that +it is perfectly harmless to the trees. Until the lime-sulphur mixture +proved to be successful the San Jose scale was a most dreaded nursery +and orchard foe. It was even thought necessary to destroy infected +trees. The lime-sulphur mixture and some other sulphur washes not only +kill the San Jose scale but are also useful in reducing fungous injury.</p> + +<div class='centered'> +<table border="0" cellpadding="0" width="60%" cellspacing="0" summary="Fig 150/151"> +<tr> +<td valign="top"><img src="images/img170a.jpg" width="170" height="200" + alt="Fig. 150." /><br /> + <b><span class="smcap">Fig. 150.

In the +state of New York this insect is causing an annual loss of about three +million dollars. The effect it has on the fruit is most clearly seen in +Fig. 152. The moth lays its egg upon the young leaves just after the +falling of the blossom. She flies on from apple to apple, depositing an +egg each time until from fifty to seventy-five eggs are deposited. The +larva, or "worm," soon hatches and eats its way into the apple. Many +affected apples ripen too soon and drop as "windfalls." Others remain on +the tree and become the common wormy apples so familiar to growers. The +larva that emerges from the windfalls moves generally to a tree, crawls +up the trunk, and spins its cocoon under a ridge in the bark. From the +cocoon the moth comes<span class='pagenum'><a name="Page_155" id="Page_155">[Pg 155]</a></span> <span class='pagenum'><a name="Page_156" id="Page_156">[Pg 156]</a></span>ready to start a new generation.

Spray the tree with arsenate of +lead as soon as the flowers fall. A former method of fighting this pest +was as follows: bands of burlap four inches wide tied around the tree +furnished a hiding-place for larvæ that came from windfalls or crawled +from wormy apples on the tree. The larvæ caught under the bands were +killed every five or six days. We know now, however, that a thorough +spraying just after the blossoms fall kills the worms and renders the +bands unnecessary. Furthermore, spraying prevents wormy apples, while +banding does not. Follow the first spraying by a second two weeks later.</p> + +<p>It is best to use lime-sulphur mixture or the Bordeaux mixture with +arsenate of lead for a spray.

Leaf Galls of<br /> Phylloxera On Clinton<br /> Grape +Leaf</span></b> + </div> + +<p><b>The Plum Curculio.</b> The plum curculio, sometimes called the plum +weevil, is a little creature about one fifth of an inch long. In spite +of its small size the curculio does, if neglected, great damage to our +fruit crop. It injures peaches, plums, and cherries by stinging the +fruit as soon as it is formed. The word "stinging" when applied to +insects—- and this case is<span class='pagenum'><a name="Page_157" id="Page_157">[Pg 157]</a></span> no exception—means piercing the object +with the egg-layer (ovipositor) and depositing the egg. Some insects +occasionally use the ovipositor merely for defense. The curculio has an +especially interesting method of laying her egg. First she digs a hole, +in which she places the egg and pushes it well down. Then with her snout +she makes a crescent-shaped cut in the skin of the plum, around the egg. +This mark is shown in Fig. 154. As this peculiar cut is followed by a +flow of gum, you will always be able to recognize the work of the +curculio. Having finished with one plum, this industrious worker makes +her way to other plums until her eggs are all laid. The maggotlike larva +soon hatches, burrows through the fruit, and causes it to drop before +ripening. The larva then enters the ground to a depth of several inches. +There it becomes a pupa, and later, as a mature beetle, emerges and +winters in cracks and crevices.</p> + + + +<p><i>Treatment.</i> Burn orchard trash which may serve as winter quarters. +Spraying with arsenate of lead, using two pounds of the mixture to fifty +gallons of water, is the only successful treatment for the curculio. For +plums and peaches, spray first when the fruit is free from the calyx +caps, or dried flower-buds. Repeat the spraying two weeks later. For +late peaches spray a third time two weeks after the second spraying. +This poisonous spray will kill the beetles while they are feeding or +cutting holes in which to lay their eggs.<span class='pagenum'><a name="Page_158" id="Page_158">[Pg 158]</a></span></p> + +<div class="figright"> + <img src="images/img175.jpg" width="282" height="400" + alt="Fig. 156." /><br /> + <b><span class="smcap">Fig. 156.

You have +no doubt seen its galls upon the grape leaf. These galls are caused by a +small louse, the phylloxera. Each gall contains a female, which soon +fills the gall with eggs. These hatch into more females, which emerge +and form new galls, and so the phylloxera spreads (see Fig. 155).</p> + +<p><i>Treatment.</i> The Clinton grape is most liable to injury from this pest. +Hence it is better to grow other more resistant kinds. Sometimes the +lice attack the roots of the grape vines. In many sections where +irrigation is practiced the grape rows are flooded when the lice are +thickest. The water drowns the lice and does no harm to the vines.<span class='pagenum'><a name="Page_159" id="Page_159">[Pg 159]</a></span></p> + +<p><b>The Cankerworm.</b> The cankerworm is the larva of a moth. Because of its +peculiar mode of crawling, by looping its body, it is often called the +looping worm or measuring worm (Fig. 157, <i>c</i>). These worms are such +greedy eaters that in a short time they can so cut the leaves of an +orchard as to give it a scorched appearance. Such an attack practically +destroys the crop and does lasting injury to the tree. The worms are +green or brown and are striped lengthwise. If the tree is jarred, the +worm has a peculiar habit of dropping toward the ground on a silken +thread of its own making (Fig. 156).</p> + +<div class="figleft"> + <img src="images/img176.jpg" width="250" height="247" + alt="Fig. 157." /><br /> + <b><span class="smcap">Fig. 157.

You observe the +peculiar difference between the wingless female, <i>d</i>, and the winged +male, <i>e</i>. It is the habit of this wingless female to crawl up the trunk +of some near-by tree in order to deposit her eggs upon the twigs. These +eggs (shown at <i>a</i> and <i>b</i>) hatch into the greedy larvæ that do so much +damage to our orchards.</p> + + + +<p>Nearly all the common birds feed freely upon the cankerworm, and benefit +the orchard in so doing. The chickadee<span class='pagenum'><a name="Page_160" id="Page_160">[Pg 160]</a></span> is perhaps the most useful. A +recent writer is very positive that each chickadee will devour on an +average thirty female cankerworm moths a day; and that if the average +number of eggs laid by each female is one hundred and eighty-five, one +chickadee would thus destroy in one day five thousand five hundred and +fifty eggs, and, in the twenty-five days in which the cankerworm moths +crawl up the tree, would rid the orchard of one hundred and thirty-eight +thousand seven hundred and fifty. These birds also eat immense numbers +of cankerworm eggs before they hatch into worms.</p> + + + +<p><i>Treatment.</i> The inability of the female to fly gives us an easy way to +prevent the larval offspring from getting to the foliage of our trees, +for we know that the only highway open to her or her larvæ leads up the +trunk. We must obstruct this highway so that no crawling creature may +pass. This is readily done by smoothing the bark and fitting close to it +a band of paper, and making sure that it is tight enough to prevent +anything from crawling underneath. Then smear over the paper something +so sticky that any moth or larva that attempts to pass will be +entangled. Printer's ink will do very well, or you can buy either +dendrolene or tanglefoot.<span class='pagenum'><a name="Page_161" id="Page_161">[Pg 161]</a></span></p> + +<div class="figcenter"> + <img src="images/img178.jpg" width="305" height="400" + alt="Fig. 159." /><br /> + <b><span class="smcap">Fig. 159.

Those plants that best serve the needs +of the farmer and of farm animals have undergone the most changes and +have received also the greatest care and attention in their production +and improvement.</p> + +<p>While we have many different kinds of farm crops, the cultivated soil of +the world is occupied by a very few. In our country the crop that is +most valuable and that occupies the greatest land area is generally +known as the <i>grass crop</i>. Included in the general term "grass crop" are +the grasses and clovers that are used for pasturage as well as for hay. +Next to grass in value come the great cereal, corn, and the most +important fiber crop, cotton, closely followed by the great bread crop, +wheat. Oats rank fifth in value, potatoes sixth, and tobacco seventh. +(These figures are for 1913.)</p> + +<p>Success in growing any crop is largely due to the suitableness of soil +and climate to that crop. When the planter selects both the most +suitable soil and the most suitable climate for each crop, he gets not +only the most bountiful yield from the crop but, in addition, he gets +the most desirable quality of product. A little careful observation and +study soon teach what kinds of soil produce crops of the highest +excellence.

COTTON</h3> + +<p>Although cotton was cultivated on the Eastern continent before America +was discovered, this crop owes its present kingly place in the business +world to the zeal and intelligence of its American growers. So great an +influence does it wield in modern industrial life that it is often +called King Cotton. Thousands upon thousands of people scan the +newspapers each day to see what price its staple is bringing. From its +bounty a vast army of toilers, who plant its seed, who pick its bolls, +who gin its staple, who spin and weave its lint, who grind its seed, who +refine its oil, draw daily bread. Does not its proper production deserve +the best thought that can be given it?</p> + +<p>In the cotton belt almost any well-drained soil will produce cotton. The +following kinds of soil are admirably suited to this plant: red and gray +loams with good clay subsoil; sandy soils over clay and sandstone and +limestone; rich, well-drained bottom-lands. The safest soils are medium +loams. Cotton land must always be well drained.</p> + +<p>Cotton was originally a tropical plant, but, strange to say, it seems to +thrive best in temperate zones. The cotton plant does best, according to +Newman, in climates which have (1) six months of freedom from frost; (2) +a moderate, well-distributed rainfall during the plant's growing period; +and (3) abundant sunshine and little rain during the plant's maturing +period.</p> + +<div class="figcenter"> + <img src="images/img200.jpg" width="400" height="254" + alt="Fig. 183." /><br /> + <b><span class="smcap">Fig. 183.

In recent +years the soil and climate of lower California and parts of Arizona and +New Mexico have been found well adapted to cotton.</p> + +<div class="figcenter"> + <img src="images/img201.jpg" width="400" height="226" + alt="Fig. 184." /><br /> + <b><span class="smcap">Fig. 184. Cotton in the Growing Season</span></b> + </div> + + +<p>There are a great many varieties of cotton. Two types are mainly grown +by the practical American farmer. These are the short-stapled, upland +variety most commonly grown in all the Southern states, and the +beautiful, long-stapled, black-seeded sea-island type that grows upon +the islands and a portion of the mainland of Georgia, South Carolina, +and Florida. The air of the coast seems necessary for the production of +this latter variety. The seeds of the sea-island cotton are small, +smooth, and black. They are so smooth and stick so loosely to the lint +that they are separated from it by roller-gins instead of by saw-gins. +When these seeds are planted away from the soil and air of their ocean +home, the plant does not thrive.<span class='pagenum'><a name="Page_183" id="Page_183">[Pg 183]</a></span></p> + +<p>Many attempts have been made and are still being made to increase the +length of the staple of the upland types. The methods used are as +follows: selection of seed having a long fiber; special cultivation and +fertilization; crossing the short-stapled cotton on the long-stapled +cotton. This last process, as already explained, is called +<i>hybridizing</i>. Many of these attempts have succeeded, and there are now +a large number of varieties which excel the older varieties in +profitable yield. The new varieties are each year being more widely +grown. Every farmer should study the new types and select the one that +will best suit his land. The new types have been developed under the +best tillage. Therefore if a farmer would keep the new type as good as +it was when he began to grow it, he must give it the same good tillage, +and practice seed-selection.</p> + +<div class="figcenter"> + <img src="images/img202.jpg" width="400" height="175" + alt="Fig. 185." /><br /> + <b><span class="smcap">Fig. 185.

This is not +a good practice. The winter rains wash more plant food out of +unprotected soil than a single crop would use. It would be better, in +the late summer or fall, to plant crimson clover or some other +protective and enriching crop on land that is to be planted in cotton in +the spring. This crop, in addition to keeping the land from being +injuriously washed, would greatly help the coming cotton crop by leaving +the soil full of vegetable matter.</p> + +<p>In preparing for cotton-planting, first disk the land thoroughly, then +break with a heavy plow and harrow until a fine and mellow seed-bed is +formed.

The width depends upon +the richness of the soil. On rich land the rows should be at least four +feet apart. This width allows the luxuriant plant to branch and fruit +well. On poorer lands the distance of the rows should not be so great. +The distribution of the seed in the row is of course most cheaply done +by the planter.

Repeat +the harrowing in six or eight days. In addition to destroying the young +grass and weeds, this harrowing also removes many of the young cotton +plants and thereby saves much hoeing at "chopping-out" time. When the +plants are about two inches high they are "chopped out" to secure an +evenly distributed stand. It has been the custom to leave two stalks to +a hill, but many growers are now leaving only one.</p> + +<p>The number of times the crop has to be worked depends on the soil and +the season. If the soil is dry and porous, cultivate as often as +possible, especially after each rain. Never allow a crust to form after +a rain; the roots of plants must have air. Cultivation after each rain +forms a dry mulch on the top of the soil and thus prevents rapid +evaporation of moisture.</p> + +<p>If the fiber (the lint) only is removed from the land on which cotton is +grown, cotton is the least exhaustive of the great crops grown in the +United States. According to some recent experiments an average crop of +cotton removes in the lint only 2.75 pounds of nitrogen, phosphoric +acid, potash, lime, and magnesia per acre, while a crop of ten bushels +of wheat per acre removes 32.36 pounds of the same elements of plant +food. Inasmuch as this crop takes so little plant food from the soil, +the cotton-farmer has no excuse for allowing his land to decrease in +productiveness. Two things will keep his land in bounteous harvest +condition: first, let him return the seeds in some form to the land, or, +what is better, feed the ground seeds to cattle, make a profit from the +cattle, and return manure to the land in place of the seeds; second, at +the last working, let him sow some crop like crimson clover or rye in +the cotton rows to protect the soil during the winter and to leave humus +in the ground for the spring.<span class='pagenum'><a name="Page_187" id="Page_187">[Pg 187]</a></span></p> + +<p>The stable manure, if that is used, should be broadcasted over the +fields at the rate of six to ten tons an acre. If commercial fertilizers +are used, it may be best to make two applications. To give the young +plants a good start, apply a portion of the fertilizer in the drill just +before planting. Then when the first blooms appear, put the remainder of +the fertilizer in drills near the plants but not too close.

TOBACCO</h3> + +<p>The tobacco plant connects Indian agriculture with our own. It has +always been a source of great profit to our people. In the early +colonial days tobacco was almost the only money crop. Many rich men came +to America in those days merely to raise tobacco.</p> + +<p>Although tobacco will grow in almost any climate, the leaves, which, as +most of you know, are the salable part of the plant, get their desirable +or undesirable qualities very largely from the soil and from the climate +in which they grow.</p> + +<div class="figright"> + <img src="images/img208.jpg" width="87" height="200" + alt="Fig. 189." /><br /> + <b><span class="smcap">Fig. 189. A Leaf of Tobacco</span></b> + </div> + +<p>The soil in which tobacco thrives best is one which has the following +qualities: dryness, warmth, richness, depth, and sandiness.</p> + +<p>Commercial fertilizers also are almost a necessity; for, as tobacco land +is limited in area, the same land must be often planted in tobacco. +Hence even a fresh, rich soil that did not at first require fertilizing +soon becomes exhausted, and, after the land has been robbed of its plant +food by crop after crop of tobacco, frequent application of fertilizers +and other manures becomes necessary. However, even tobacco growers +should rotate their crops as much as possible.</p> + + + +<p>Deep plowing—from nine to thirteen inches—is also a necessity in +preparing the land, for tobacco roots go deep into the soil. After this +deep plowing, harrow until the soil is thoroughly pulverized and is as +fine and mellow as that of the flower-garden.<span class='pagenum'><a name="Page_190" id="Page_190">[Pg 190]</a></span></p> + +<p>Unlike most other farm crops the tobacco plant must be started first in +a seed-bed. To prepare a tobacco bed the almost universal custom has +been to proceed as follows. Carefully select a protected spot. Over this +spot pile brushwood and then burn it. The soil will be left dry, and all +the weed seeds will be killed. The bed is then carefully raked and +smoothed and planted. Some farmers are now preparing their beds without +burning. A tablespoonful of seed will sow a patch twenty-five feet +square. A cheap cloth cover is put over the bed. If the seeds come up +well, a patch of this size ought to furnish transplants for five or six +acres. In sowing, it is not wise to cover the seed deeply. A light +raking in or an even rolling of the ground is all that is needed.</p> + +<div class="figcenter"> + <img src="images/img209.jpg" width="400" height="277" + alt="Fig. 190." /><br /> + <b><span class="smcap">Fig. 190.

The rows should be from three +to three and a half feet apart, and the plants in the rows about two or +three feet apart. If the plants are set so that the plow and cultivator +can be run with the rows and also across the rows, they can be more +economically worked. Tobacco, like corn, requires shallow cultivation. +Of course the plants should be worked often enough to give clean culture +and to provide a soil mulch for saving moisture.</p> + + +<p>In tobacco culture it is necessary to pinch off the "buttons" and to cut +off the tops of the main stalk, else much nourishment that should go to +the leaves will be given to the seeds.

Briefly, we may say +that tobacco is ready to be cut when the leaves on being held up to the +sun show a light or golden color, when they are sticky to the touch, and +when they break easily on being bent. Plants that are overripe are +inferior to those that are cut early.</p> + +<p>The operations included in cutting, housing, drying, shipping, sweating, +and packing require skill and practice.</p> + + +<h3>SECTION XXXVII.

The only way to come to reliable conclusions as to the needs<span class='pagenum'><a name="Page_205" id="Page_205">[Pg 205]</a></span> +of the soil is to try two or three different kinds of fertilizers on +plats of the same soil, during the same season, and notice the resulting +crop of potatoes.</p> + +<p>Sweet potatoes will do well after almost any of the usual field crops. +This caution, however, should be borne in mind. Potatoes should not +follow a sod. This is because sods are often thick with cutworms, one of +the serious enemies of the potato.</p> + +<p>It is needless to say that the ground must be kept clean by thorough +cultivation until the vines take full possession of the field.</p> + +<p>In harvesting, extreme care should be used to avoid cutting and bruising +the potato, since bruises are as dangerous to a sweet potato as to an +apple, and render decay almost a certainty. Lay aside all bruised +potatoes for immediate use.</p> + +<p>For shipment the potatoes should be graded and packed with care. An +extra outlay of fifty cents a barrel often brings a return of a dollar a +barrel in the market. One fact often neglected by Southern growers who +raise potatoes for a Northern market is that the Northern markets demand +a potato that will cook dry and mealy, and that they will not accept the +juicy, sugary potato so popular in the South.</p> + +<p>The storage of sweet potatoes presents difficulties owing to their great +tendency to decay under the influence of the ever-present fungi and +bacteria. This tendency can be met by preventing bruises and by keeping +the bin free from rotting potatoes. The potatoes should be cleaned, and +after the moisture has been dried off they should be stored in a dry, +warm place.</p> + +<p>The sweet-potato vine makes a fair quality of hay and with proper +precaution may be used for ensilage. Small, defective, unsalable +potatoes are rich in sugar and starch and are therefore good stock food. +Since they contain so much water they must be used only as an aid to +other diet.<span class='pagenum'><a name="Page_206" id="Page_206">[Pg 206]</a></span></p> + + +<h3>SECTION XLI. WHITE, OR IRISH, POTATOES</h3> + +<p>Maize, or Indian corn, and potatoes are the two greatest gifts in the +way of food that America has bestowed on the other nations. Since their +adoption in the sixteenth century as a new food from recently discovered +America, white potatoes have become one of the world's most important +crops.</p> + +<div class="figcenter"> + <img src="images/img225.jpg" width="400" height="260" + alt="Fig. 204." /><br /> + <b><span class="smcap">Fig. 204. Cultivating and Ridging Potatoes</span></b> + </div> + +<p>No grower will harvest large crops of potatoes unless he chooses soil +that suits the plant, selects his seed carefully, cultivates thoroughly, +feeds his land sufficiently, and sprays regularly.</p> + +<p>The soil should be free from potato scab. This disease remains in land +for several years. Hence if land is known to have any form of scab in +it, do not plant potatoes in such land. Select for this crop a deep and +moderately light, sandy loam which has an open subsoil and which is rich +in humus. The soil must be light enough for the potatoes, or<span class='pagenum'><a name="Page_207" id="Page_207">[Pg 207]</a></span> tubers, to +enlarge easily and dry enough to prevent rot or blight or other +diseases. Potato soil should be so close-grained that it will hold +moisture during a dry spell and yet so well-drained that the tubers will +not be hurt by too much moisture in wet weather.</p> + +<p>If the land selected for potatoes is lacking in humus, fine compost or +well-rotted manure will greatly increase the yield. However, it should +be remembered that green manure makes a good home for the growth of scab +germs. Hence it is safest to apply this sort of manure in the fall, or, +better still, use a heavy dressing of manure on the crop which the +potatoes are to follow. Leguminous crops supply both humus and nitrogen +and, at the same time, improve the subsoil. Therefore such crops are +excellent to go immediately before potatoes. If land is well supplied +with humus, commercial fertilizers are perhaps safer than manure, for +when these fertilizers are used the amount of plant food is more easily +regulated. Select a fertilizer that is rich in potash. For gardens +unleached wood ashes make a valuable fertilizer because they supply +potash. Early potatoes need more fertilization than do late ones. While +potatoes do best on rich land, they should not be overfed, for a too +heavy growth of foliage is likely to cause blight.</p> + +<p>Be careful to select seed from sound potatoes which are entirely free +from scab. Get the kinds that thrive best in the section in which they +are to be planted and which suit best the markets in which they are to +be sold. Seed potatoes should be kept in a cool place so that they will +not sprout before planting-time. As a rule consumers prefer a smooth, +regularly shaped, shallow-eyed white or flesh-colored potato which is +mealy when cooked. Therefore, select seed tubers with these qualities. +It seems proved that when whole potatoes are used for seed the yield is +larger than when sliced<span class='pagenum'><a name="Page_208" id="Page_208">[Pg 208]</a></span> potatoes are planted. It is of course too +costly to plant whole potatoes, but it is a good practice to cause the +plants to thrive by planting large seed pieces.</p> + +<div class="figcenter"> + <img src="images/img227.jpg" width="400" height="299" + alt="Fig. 205." /><br /> + <b><span class="smcap">Fig. 205. Gathering Potatoes</span></b> + </div> + +<p>Like other crops, potatoes need a thoroughly prepared seed-bed and +intelligent cultivation. Break the land deep. Then go over it with an +ordinary harrow until all clods are broken and the soil is fine and well +closed. The rows should be at least three feet from one another and the +seeds placed from twelve to eighteen inches apart in the row, and +covered to a depth of three or four inches. A late crop should be +planted deeper than an early one. Before the plants come up it is well +to go over the field once or twice with a harrow so as to kill all +weeds. Do not fail to save moisture by frequent cultivation. After the +plants start to grow, all cultivation should be shallow, for the roots +feed near the surface<span class='pagenum'><a name="Page_209" id="Page_209">[Pg 209]</a></span> and should not be broken. Cultivate as often as +needed to keep down weeds and grass and to keep the ground fine.</p> + +<p>Allow potatoes to dry thoroughly before they are stored, but never allow +them to remain long in the sunshine. Never dig them in damp weather, for +the moisture clinging to them will cause them to rot. After the tubers +are dry, store them in barrels or bins in a dry, cool, and dark place. +Never allow them to freeze.</p> + +<p>Among the common diseases and insect pests that attack the leaves and +stems of potato vines are early blight, late blight, brown rot, the +flea-beetle, and the potato beetle, or potato bug. Spraying with +Bordeaux mixture to which a small portion of Paris green has been added +will control both the diseases and the pests. The spraying should begin +when the plants are five or six inches high and should not cease until +the foliage begins to die.</p> + +<p>Scab is a disease of the tubers. It may be prevented (1) by using seed +potatoes that are free from scab; (2) by planting land in which there is +no scab; and (3) by soaking the seed in formalin (see page 135).</p> + + +<h3>SECTION XLII. OATS</h3> + +<p>The oat plant belongs to the grass family. It is a hardy plant and, +under good conditions, a vigorous grower. It stands cold and wet better +than any other cereal except possibly rye. Oats like a cool, moist +climate. In warm climates, oats do best when they are sowed in the fall. +In cooler sections, spring seeding is more generally practiced.</p> + +<div class="figleft"> + <img src="images/img229.jpg" width="140" height="200" + alt="Fig. 206." /><br /> + <b><span class="smcap">Fig. 206. Oats</span><br />Common oats at left; <br />side oats at right</b> + </div> + +<p>There are a great many varieties of oats. No one variety is best adapted +to all sections, but many varieties make fine crops in many sections. +Any variety is desirable which has<span class='pagenum'><a name="Page_210" id="Page_210">[Pg 210]</a></span> these qualities: power to resist +disease and insect enemies, heavy grains, thin hulls, good color, and +suitability to local surroundings.</p> + + + +<p>As oats and rye make a better yield on poor land than any other cereals, +some farmers usually plant these crops on their poorest lands. However, +no land is too good to be used for so valuable a crop as oats. Oats +require a great deal of moisture; hence light, sandy soils are not so +well adapted to this crop as are the sandy loams and fine clay loams +with their closer and heavier texture.</p> + +<p>If oats are to be planted in the spring, the ground should be broken in +the fall, winter, or early spring so that no delay may occur at +seeding-time. But to have a thoroughly settled, compact seed-bed the +breaking of the land should be done at least a month before the seeding, +and it will help greatly to run over the land with a disk harrow +immediately after the breaking.</p> + + + +<p>Oats may be planted by scattering them broadcast or by means of a drill. +The drill is better, because the grains are more uniformly distributed +and the depth of planting is better regulated. The seeds should be +covered from one and a half to two inches deep. In a very dry season +three inches may not be too deep. The amount of seed needed to the acre<span class='pagenum'><a name="Page_211" id="Page_211">[Pg 211]</a></span> +varies considerably, but generally the seeding is from two to three +bushels an acre. On poor lands two bushels will be a fair average +seeding; on good lands as much as three bushels should be used.</p> + +<div class="figcenter"> + <img src="images/img230.jpg" width="400" height="297" + alt="Fig. 207." /><br /> + <b><span class="smcap">Fig. 207. Harvesting Oats</span></b> + </div> + +<p>This crop fits in well, over wide areas, with various rotations. As the +purpose of all rotation is to keep the soil productive, oats should +alternate every few years with one of the nitrogen-gathering crops. In +the South, cowpeas, soy beans, clovers, and vetches may be used in this +rotation. In the North and West the clovers mixed with timothy hay make +a useful combination for this purpose.</p> + +<p>Spring-sowed oats, since they have a short growing season, need their +nitrogenous plant food in a form which can be quickly used. To supply +this nitrogen a top-dressing of nitrate of soda or sulphate of lime is +helpful. The plant<span class='pagenum'><a name="Page_212" id="Page_212">[Pg 212]</a></span> can gather its food quickly from either of these +two. As fall-sowed oats have of course a longer growing season, the +nitrogen can be supplied by well-rotted manure, blood, tankage, or +fish-scrap. Use barnyard manure carefully. Do not apply too much just +before seeding, and use only thoroughly rotted manure. It is always +desirable to have a bountiful supply of humus in land on which oats are +to be planted.</p> + +<p>The time of harvesting will vary with the use which is to be made of the +oats. If the crop is to be threshed, the harvesting should be done when +the kernels have passed out of the milk into the hard dough state. The +lower leaves of the stalks will at this time have turned yellow, and the +kernels will be plump and full. Do not, however, wait too long, for if +you do the grain will shatter and the straw lose in feeding value.</p> + +<p>On the other hand, if the oats are to be cut for hay it is best to cut +them while the grains are still in the milk stage. At this stage the +leaves are still green and the plants are rich in protein.</p> + +<p>Oats should be cured quickly. It is very important that threshed oats +should be dry before they are stored. Should they on being stored still +contain moisture, they will be likely to heat and to discolor. Any +discoloring will reduce their value. Nor should oats ever be allowed to +remain long in the fields, no matter how well they may seem to be +shocked. The dew and the rain will injure their value by discoloring +them more or less.</p> + +<p>Oats are muscle-builders rather than fat-formers. Hence they are a +valuable ration for work animals, dairy cows, and breeding-stock.<span class='pagenum'><a name="Page_213" id="Page_213">[Pg 213]</a></span></p> + + +<h3>SECTION XLIII. RYE</h3> + +<p>Rye has the power of gathering its food from a wider area than most +other plants. Of course, then, it is a fine crop for poor land, and +farmers often plant it only on worn land. However, it is too good a +cereal to be treated in so ungenerous a fashion. As a cover-crop for +poor land it adds much humus to the soil and makes capital grazing.</p> + +<div class="figcenter"> + <img src="images/img232.jpg" width="389" height="400" + alt="Fig. 208." /><br /> + <b><span class="smcap">Fig. 208. Rye ready for Cutting</span></b> + </div> + + +<p>There are two types of rye—the winter and the spring. The winter type +is chiefly grown in this country. Rye seeds<span class='pagenum'><a name="Page_214" id="Page_214">[Pg 214]</a></span> should be bought as near +home as possible, for this plant thrives best when the new crop grows +under the same conditions as the seed crop.</p> + +<p>Rye will grow on almost any soil that is drained. Soils that are too +sandy for wheat will generally yield good crops of rye. Clay soils, +however, are not adapted to the plant nor to the grazing for which the +plant is generally sowed. For winter rye the land should be broken from +four to six inches. Harrows should follow the plows until the land is +well pulverized. In some cold prairie lands, however, rye is put in with +a grain-drill before a plow removes the stubble from the land. The +purpose of planting in this way is to let the stubble protect the young +plants from cold, driving winds.</p> + +<p>Rye should go into the ground earlier than wheat. In cold, bleak +climates, as well as on poor land, the seeding should be early. The +young plant needs to get rooted and topped before cold weather sets in. +The only danger in very early planting is that leaf-rust sometimes +attacks the forward crop. Of course the earlier the rye is ready for +fall and winter pasturage, the better. If a drill is used for planting, +a seeding of from three to four pecks to the acre should give a good +stand. In case the seeds are to be sowed broadcast, a bushel or a bushel +and a half for every acre is needed. The seed should be covered as wheat +seed is and the ground rolled.</p> + +<p>Rye is generally used as a grazing or as a soiling crop. Therefore its +value will depend largely on its vigorous growth in stems and leaves. To +get this growth, liberal amounts of nitrogenous fertilizer will have to +be applied unless the land is very rich. Put barnyard manure on the land +just after the first breaking and disk the manure into the soil. Acid +phosphate and kainite added to the manure may pay handsomely. A spring +top-dressing of nitrate of soda is usually helpful.<span class='pagenum'><a name="Page_215" id="Page_215">[Pg 215]</a></span></p> + +<p>Rye has a stiff straw and does not fall, or "lodge," so badly as some of +the other cereals. As soon as rye that is meant for threshing is cut, it +should be put up in shocks until it is thoroughly dry. Begin the cutting +when the kernels are in a tough dough state. The grain should never +stand long in the shocks.</p> + + +<h3>SECTION XLIV. BARLEY</h3> + +<p>Barley is one of the oldest crops known to man. The old historian Pliny +says that barley was the first food of mankind. Modern man however +prefers wheat and corn and potatoes to barley, and as a food this +ancient crop is in America turned over to the lower animals. Brewers use +barley extensively in making malt liquors. Barley grows in nearly all +sections of our country, but a few states—namely, Minnesota, +California, Wisconsin, Iowa, and North and South Dakota—are seeding +large areas to this crop.</p> + +<p>For malting purposes the barley raised on rather light, friable, porous +soil is best. Soils of this kind are likely to produce a medium yield of +bright grain. Fertile loamy and clay soils make generally a heavier +yield of barley, but the grain is dark and fit only to be fed to stock. +Barley is a shallow feeder, and can reach only such plant food as is +found in the top soil, so its food should always be put within reach by +a thorough breaking, harrowing, and mellowing of the soil, and by +fertilizing if the soil is poor. Barley has been successfully raised +both by irrigation and by dry-farming methods. It requires a +better-prepared soil than the other grain crops; it makes fine yields +when it follows some crop that has received a heavy dressing of manure. +Capital yields are produced after alfalfa or after root crops. This crop +usually matures within a hundred days from its seeding.<span class='pagenum'><a name="Page_216" id="Page_216">[Pg 216]</a></span></p> + +<div class="figcenter"> + <img src="images/img235.jpg" width="400" height="266" + alt="Fig. 209." /><br /> + <b><span class="smcap">Fig. 209. Barley</span></b> + </div> + +<p>When the crop is to be sold to the brewers, a grain rich in starch +should be secured. Barley intended for malting should be fertilized to +this end. Many experiments have shown that a fertilizer which contains +much potash will produce starchy barley. If the barley be intended for +stock, you should breed so as to get protein in the grain and in the +stalk. Hence barley which is to be fed should be fertilized with +mixtures containing nitrogen and phosphoric acid. Young barley plants +are more likely to be hurt by cold than either wheat or oats. Hence +barley ought not to be seeded until all danger from frost is over. The +seeds should be covered deeper than the seeds of wheat or of oats. Four +inches is perhaps an average depth for covering. But the covering will +vary with the time of planting, with the kind of ground, with the +climate, and with the nature of the season. Fewer seeds will be needed +if the barley is planted by means of a drill.<span class='pagenum'><a name="Page_217" id="Page_217">[Pg 217]</a></span></p> + +<p>Like other cereals, barley should not be grown continuously on the same +land. It should take its place in a well-planned rotation. It may +profitably follow potatoes or other hoed crops, but it should not come +first after wheat, oats, or rye.</p> + +<p>Barley should be harvested as soon as most of its kernels have reached +the hard dough state. It is more likely to shatter its grain than are +other cereals, and it should therefore be handled with care. It must +also be watched to prevent its sprouting in the shocks. Be sure to put +few bundles in the shock and to cap the shock securely enough to keep +out dew and rain. If possible the barley should be threshed directly +from the shock, as much handling will occasion a serious loss from +shattering.</p> + + +<h3>SECTION XLV. SUGAR PLANTS</h3> + +<p>In the United States there are three sources from which sugar is +obtained; namely, the sugar-maple, the sugar-beet, and the sugar-cane. +In the early days of our country considerable quantities of maple sirup +and maple sugar were made. This was the first source of sugar. Then +sugar-cane began to be grown. Later the sugar-beet was introduced.</p> + +<p><b>Maple Products.</b> In many states sirup and sugar are still made from +maple sap. In the spring when the sap is flowing freely maple trees are +tapped and spouts are inserted. Through these spouts the sap flows into +vessels set to catch it. The sap is boiled in evaporating-pans, and made +into either sirup or sugar. Four gallons of sap yield about one pound of +sugar. A single tree yields from two to six pounds of sugar in a season. +The sap cannot be kept long after it is collected. Practice and skill +are needed to produce an attractive and palatable grade of sirup or of +sugar.<span class='pagenum'><a name="Page_218" id="Page_218">[Pg 218]</a></span></p> + +<p><b>Sugar-Beets.</b> The sugar-beet is a comparatively new root crop in +America. The amount of sugar that can be obtained from beets varies from +twelve to twenty per cent. The richness in sugar depends somewhat on the +variety grown and on the soil and the climate.</p> + +<p>So far most of our sugar-beet seeds have been brought over from Europe. +Some of our planters are now, however, gaining the skill and the +knowledge needed to grow these seeds. It is of course important to grow +seeds that will produce beets containing much sugar.</p> + + +<div class="figcenter"> + <img src="images/img237.jpg" width="400" height="281" + alt="Fig. 210." /><br /> + <b><span class="smcap">Fig. 210. Catching Maple Sap</span></b> + </div> + +<p>These beets do well in a great variety of soils if the land is rich, +well prepared, and well drained, and has a porous subsoil.</p> + +<p>Beets cannot grow to a large size in hard land. Hence deep plowing is +very necessary for this crop. The soil should<span class='pagenum'><a name="Page_219" id="Page_219">[Pg 219]</a></span> be loose enough for the +whole body of the beet to remain underground. Some growers prefer spring +plowing and some fall plowing, but all agree that the land should not be +turned less than eight or ten inches. The subsoil, however, should not +be turned up too much at the first deep plowing.</p> + +<div class="figright"> + <img src="images/img238.jpg" width="114" height="200" + alt="Fig. 211." /><br /> + <b><span class="smcap">Fig. 211. Sugar-Beet</span></b> + </div> + +<p>Too much care cannot be taken to make the seed-bed firm and mellow and +to have it free from clods. If the soil is dry at planting-time and +there is likelihood of high winds, the seed-bed may be rolled with +profit. Experienced growers use from ten to twelve pounds of seeds to an +acre. It is better to use too many rather than too few seeds, for it is +easy to thin out the plants, but rather difficult to transplant them. +The seeds are usually drilled in rows about twenty inches apart. Of +course, if the soil is rather warm and moist at planting-time, fewer +seeds will be needed than when germination is likely to be slow.</p> + + + +<p>A good rotation should always be planned for this beet. A very +successful one is as follows: for the first year, corn heavily +fertilized with stable manure; for the second year, sugar-beets; for the +third year, oats or barley; for the fourth year, clover; then go back +again to corn. In addition to keeping the soil fertile, there are two +gains from this rotation: first, the clean cultivation of the corn crop +just ahead of the beets destroys many of the weed seeds; second, the<span class='pagenum'><a name="Page_220" id="Page_220">[Pg 220]</a></span> +beets must be protected from too much nitrogen in the soil, for an +excess of nitrogen makes a beet too large to be rich in sugar. The +manure, heavily applied to the corn, will leave enough nitrogen and +other plant food in the soil to make a good crop of beets and avoid any +danger of an excess.</p> + +<p>When the outside leaves of the beet take on a yellow tinge and drop to +the ground, the beets are ripe. The mature beets are richer in sugar +than the immature, therefore they should not be harvested too soon. They +may remain in the ground without injury for some time after they are +ripe. Cold weather does not injure the roots unless it is accompanied by +freezing and thawing.</p> + +<div class="figcenter"> + <img src="images/img239.jpg" width="400" height="285" + alt="Fig. 212." /><br /> + <b><span class="smcap">Fig. 212. Sugar-Beets on the way to a Factory</span></b> + </div> + + +<p>The beets are harvested by sugar-beet pullers or by hand. If the roots +are to be gathered by hand they are usually loosened by plowing on each +side of them. If the roots are stored they should be put in long, narrow +piles and covered<span class='pagenum'><a name="Page_221" id="Page_221">[Pg 221]</a></span> with straw and earth to protect them from frost. A +ventilator placed at the top of the pile will enable the heat and +moisture to escape. If the beets get too warm they will ferment and some +of their sugar will be lost.</p> + + +<p><b>Sugar-Cane.</b> Sugar-cane is grown along the Gulf of Mexico and the South +Atlantic coast. In Mississippi, in Alabama, Florida, Georgia, South +Carolina, northern Louisiana, and in northern Texas it is generally made +into sirup. In southern Louisiana and southern Texas the cane is usually +crushed for sugar or for molasses.</p> + +<div class="figright"> + <img src="images/img240.jpg" width="151" height="350" + alt="Fig. 213." /><br /> + <b><span class="smcap">Fig. 213.

Some are white, some yellow, some green, some +red, some purple, and some black, while others are a mixture of two or +three of these colors. As shown in Fig. 214 the stalk has joints at +distances of from two to six inches. These joints are called nodes, and +the sections between the nodes are known as internodes.

From this eye the cane is usually propagated; for, while in +tropical countries the cane forms seeds, yet these seeds are rarely +fertile. When the cane is ripe it is stripped of leaves, topped, and cut +at the ground with a knife. The sugar is contained in solution in the +pith of the cane.</p> + +<p>Cane requires an enormous amount of water for its best growth, and where +the rainfall is not great enough, the plants are irrigated. It requires +from seventy-five to one hundred gallons of water to make a pound of +sugar. Cane does best where there is a rainfall of two inches a week. At +the same time a well-drained soil is necessary to make vigorous canes.</p> + +<p>The soils suited to this plant are those which contain large amounts of +fertilizing material and which can hold much water.

From one to three continuous lines of stalks +are placed in the furrow. From two to six tons of seed cane are needed +for an acre. In favorable weather the cane soon sprouts and cultivation +begins. Cane should be cultivated at short intervals until the plants +are large enough to shade the soil. In Louisiana one planting of cane +usually gives two crops. The first is called plant cane; the second is +known as first-year stubble, or ratoon.

The juice is then +evaporated in a kettle or pan. This equipment is very cheap and can +easily be operated by a small family. While these mills rarely extract +more than one half of the juice in the cane, the sirup made by them is +very palatable and usually commands a good price. Costly machinery which +saves most of the juice is used in the large commercial sugar houses.</p> + + +<h3>SECTION XLVI. HEMP AND FLAX</h3> + +<p>In the early ages of the world, mankind is supposed to have worn very +little or no clothing. Then leaves and the inner bark of trees were +fashioned into a protection from the weather. These flimsy garments were +later replaced by skins and furs. As man advanced in knowledge, he +learned how to twist wool and hairs into threads and to weave these into +durable garments. Still later, perhaps, he discovered that some plants +conceal under their outer bark soft, tough fibers that can be changed +into excellent cloth. Flax and hemp were doubtless among the first +plants to furnish this fiber.</p> + + +<p><b>Flax.</b> Among the fiber crops of the world, flax ranks next to cotton. +It is the material from which is woven the linen for sheets, towels, +tablecloths, shirts, collars, dresses, and a host of other articles. +Fortunately for man, flax will thrive in many countries and in many +climates. The fiber from<span class='pagenum'><a name="Page_227" id="Page_227">[Pg 227]</a></span> which these useful articles are made, unlike +cotton fiber, does not come from the fruit, but from the stem. It is the +soft, silky lining of the bark which lies between the woody outside and +the pith cells of the stem.</p> + +<div class="figright"> + <img src="images/img246.jpg" width="121" height="200" + alt="Fig. 218." /><br /> + <b><span class="smcap">Fig. 218. Flax</span></b> + </div> + +<p>The Old World engages largely in flax culture and flax manufacture, but +in our country flax is grown principally for its seed. From the seeds we +make linseed oil, linseed-oil cake, and linseed meal.</p> + +<p>Flax grows best on deep, loamy soils, but also makes a profitable growth +on clay soils. With sufficient fertilizing material it can be grown on +sandy lands. Nitrogen is especially needed by this plant and should be +liberally supplied. To meet this demand for nitrogen, it pays to plant a +leguminous crop immediately before flax.</p> + + +<p>After a mellow seed-bed has been made ready and after the weather is +fairly warm, sow, if a seed crop is desired, at the rate of from two to +three pecks an acre. A good seed crop will not be harvested if the +plants are too thick. On the other hand, if a fiber crop is to be +raised, it is desirable to plant more thickly, so that the stalks may +not branch, but run up into a single stem. From a bushel to two bushels +of seed is in this case used to an acre. Flax requires care and work +from start to finish.</p> + +<p>When the seeds are full and plump the flax is ready for harvesting. In +America a binder is generally used for<span class='pagenum'><a name="Page_228" id="Page_228">[Pg 228]</a></span> cutting the stalks. Our average +yield of flax is from eight to fifteen bushels an acre.</p> + +<p><b>Hemp.</b> Like flax, hemp adapts itself wonderfully to many countries and +many climates. However, in America most of our hemp is grown in +Kentucky.</p> + +<div class="figcenter"> + <img src="images/img247.jpg" width="400" height="302" + alt="Fig. 219." /><br /> + <b><span class="smcap">Fig. 219. Cutting Hemp</span></b> + </div> + +<p>Hemp needs soil rich enough to give the young plants a very rapid growth +in their early days so that they may form long fibers. To give this crop +abundant nitrogen without great cost, it should be grown in a rotation +which includes one of the legumes. Rich, well-drained bottom-lands +produce the largest yields of hemp, but uplands which have been heavily +manured make profitable yields.</p> + +<p>The ground for hemp is prepared as for other grain crops. The seed is +generally broadcasted for a fiber crop and then harrowed in. No +cultivation is required after seeding.<span class='pagenum'><a name="Page_229" id="Page_229">[Pg 229]</a></span></p> + +<p>If hemp is grown for seed, it is best to plant with a drill so that the +crop may be cultivated. The stalks after being cut are put in shocks +until they are dry. Then the seeds are threshed. Large amounts of hemp +seed are sold for caged birds and for poultry; it is also used for +paint-oils.</p> + + +<h3>SECTION XLVII. BUCKWHEAT</h3> + +<p>Buckwheat shares with rye and cowpeas the power to make a fairly good +crop on poor land. At the same time, of course, a full crop can be +expected only from fertile land.</p> + +<p>The three varieties most grown in America are the common gray, the +silver-hull, and the Japanese. The seeds of the common gray are larger +than the silver-hull, but not so large as the Japanese. The seeds from +the gray variety are generally regarded as inferior to the other two. +This crop is grown to best advantage in climates where the nights are +cool and moist. It matures more quickly than any other grain crop and is +remarkably free from disease. The yield varies from ten to forty bushels +an acre. Buckwheat does not seem to draw plant food heavily from the +soil and can be grown on the same land from year to year.</p> + +<p>In fertilizing buckwheat land, green manures and rich nitrogenous +fertilizers should be avoided. These cause such a luxuriant growth that +the stalks lodge badly.</p> + +<p>The time of seeding will have to be settled by the height of the land +and by the climate. In northern climates and in high altitudes the +seeding is generally done in May or June. In southern climates and in +low altitudes the planting may wait until July or August. The plant +usually matures in about seventy days. It cannot stand warm weather at +blooming-time, and must always be planted so that it may escape<span class='pagenum'><a name="Page_230" id="Page_230">[Pg 230]</a></span> warm +weather in its blooming period and cold weather in its maturing season. +The seeds are commonly broadcasted at an average rate of four pecks to +the acre. If the land is loose and pulverized, it should be rolled.</p> + +<div class="figcenter"> + <img src="images/img249.jpg" width="400" height="269" + alt="Fig. 220." /><br /> + <b><span class="smcap">Fig. 220. Buckwheat in Shock</span></b> + </div> + +<p>Buckwheat ripens unevenly and will continue to bloom until frost. +Harvesting usually begins just after the first crop of seeds have +matured. To keep the grains from shattering, the harvesting is best done +during damp or cloudy days or early in the morning while the dew is +still on the grain. The grain should be threshed as soon as it is dry +enough to go through the thresher.</p> + +<p>Buckwheat is grown largely for table use. The grain is crushed into a +dark flour that makes most palatable breakfast cakes. The grain, +especially when mixed with corn, is becoming popular for poultry food. +The middlings, which are rich in fats and protein, are prized for dairy +cows.<span class='pagenum'><a name="Page_231" id="Page_231">[Pg 231]</a></span></p> + + +<h3>SECTION XLVIII. RICE</h3> + +<p>The United States produces only about one half of the rice that it +consumes. There is no satisfactory reason for our not raising more of +this staple crop, for five great states along the Gulf of Mexico are +well adapted to its culture.</p> + +<div class="figcenter"> + <img src="images/img250.jpg" width="500" height="199" + alt="Fig. 221." /><br /> + <b><span class="smcap">Fig. 221. Threshing Rice</span></b> + </div> + + + +<p>There are two distinct kinds of rice, upland rice and lowland rice. +Upland rice demands in general the same methods of culture that are +required by other cereals, for example, oats or wheat. The growing of +lowland rice is considerably more difficult and includes the necessity +of flooding the fields with water at proper times.</p> + +<p>A stiff, half-clay soil with some loam is best suited to this crop. The +soil should have a clay subsoil to retain water and to give stiffness +enough to allow the use of harvesting-machinery. Some good rice soils +are so stiff that they must be flooded to soften them enough to admit of +plowing. Plow deeply to give the roots ample feeding-space. Good +tillage, which is too often neglected, is valuable.</p> + +<p>Careful seed-selection is perhaps even more needed for rice than for any +other crop. Consumers want kernels of the same size. Be sure that your +seed is free from red rice and<span class='pagenum'><a name="Page_232" id="Page_232">[Pg 232]</a></span> other weeds. Drilling is much better +than broadcasting, as it secures a more even distribution of the seed.</p> + +<p>The notion generally prevails that flooding returns to the soil the +needed fertility. This may be true if the flooding-water deposits much +silt, but if the water be clear it is untrue, and fertilizers or +leguminous crops are needed to keep up fertility. Cowpeas replace the +lost soil-elements and keep down weeds, grasses, and red rice.</p> + +<p>Red rice is a weed close kin to rice, but the seed of one will not +produce the other. Do not allow it to get mixed and sowed with your rice +seed or to go to seed in your field.</p> + + +<h3>SECTION XLIX. THE TIMBER CROP</h3> + +<p>Forest trees are not usually regarded as a crop, but they are certainly +one of the most important crops. We should accustom ourselves to look on +our trees as needing and as deserving the same care and thought that we +give to our other field crops. The total number of acres given to the +growth of forest trees is still enormous, but we should each year add to +this acreage.</p> + +<p>Unfortunately very few forests are so managed as to add yearly to their +value and to preserve a model stand of trees. Axmen generally fell the +great trees without thought of the young trees that should at once begin +to fill the places left vacant by the fallen giants. Owners rarely study +their woodlands to be sure that the trees are thick enough, or to find +out whether the saplings are ruinously crowding one another. Disease is +often allowed to slip in unchecked. Old trees stand long after they have +outlived their usefulness.</p> + +<p>The farm wood-lot, too, is often neglected. As forests are being swept +away, fuel is of course becoming scarcer and<span class='pagenum'><a name="Page_233" id="Page_233">[Pg 233]</a></span> more costly. Every farmer +ought to plant trees enough on his waste land to make sure of a constant +supply of fuel. The land saved for the wood-lot should be selected from +land unfit for cultivation. Steep hillsides, rocky slopes, ravines, +banks of streams—these can, without much expense or labor, be set in +trees and insure a never-ending fuel supply.</p> + +<div class="figcenter"> + <img src="images/img252.jpg" width="400" height="281" + alt="Fig. 222." /><br /> + <b><span class="smcap">Fig. 222. Wood Lot</span><br />Before proper treatment</b> + </div> + +<p>The most common enemies of the forest crop are:</p> + +<p>First, forest fires. The waste from forest fires in the United States is +most startling. Many of these fires are the result of carelessness or +ignorance. Most of the states have made or are now making laws to +prevent and to control such fires.</p> + +<p>Second, fungous diseases. The timber loss from these diseases is +exceedingly great.</p> + +<p>Third, insects of many kinds prey on the trees. Some strip all the +leaves from the branches. Others bore into the<span class='pagenum'><a name="Page_234" id="Page_234">[Pg 234]</a></span> roots, trunk, or +branches. Some lead to a slow death; others are more quickly fatal.</p> + +<p>Fourth, improper grazing. Turning animals into young woods may lead to +serious loss. The animals frequently ruin young trees by eating all the +foliage. Hogs often unearth and consume most of the seeds needed for a +good growth.</p> + +<div class="figcenter"> + <img src="images/img253.jpg" width="400" height="275" + alt="Fig. 223." /><br /> + <b><span class="smcap">Fig. 223. Wood Lot</span><br />After proper treatment</b> + </div> + + +<p>The handling of forests is a business just as the growing of corn is a +business. In old forests, dead and dying trees should be cut. Trees that +occupy space and yet have little commercial value should give way to +more valuable trees. A quick-growing tree, if it is equally desirable, +should be preferred to a slow grower. An even distribution of the trees +should be secured.</p> + +<p>In all there are about five hundred species of trees which are natives +of the United States. Probably not over seventy<span class='pagenum'><a name="Page_235" id="Page_235">[Pg 235]</a></span> of these are desirable +for forests. In selecting trees to plant or to allow to grow from their +own seeding, pick those that make a quick growth, that have a steady +market value, and that suit the soil, the place of growth, and the +climate.</p> + + +<h3>SECTION L. THE FARM GARDEN</h3> + +<p>Every farmer needs a garden in which to grow not only vegetables but +small fruits for the home table.</p> + +<p>The garden should always be within convenient distance of the farmhouse. +If possible, the spot selected should have a soil of mixed loam and +clay. Every foot of soil in the garden should be made rich and mellow by +manure and cultivation. The worst soils for the home garden are light, +sandy soils, or stiff, clayey soils; but any soil, by judicious and +intelligent culture, can be made suitable.</p> + +<p>In laying out the garden we should bear in mind that hand labor is the +most expensive kind of labor. Hence we should not, as is commonly done, +lay off the garden spot in the form of a square, but we should mark off +for our purpose a long, narrow piece of land, so that the cultivating +tools may all be conveniently drawn by a horse or a mule. The use of the +plow and the horse cultivator enables the cultivation of the garden to +be done quickly, easily, and cheaply.</p> + +<p>Each vegetable or fruit should be planted in rows, and not in little +patches. Beginning with one side of the garden the following plan of +arrangement is simple and complete: two rows to corn for table use; two +to cabbages, beets, radishes, and eggplants; two to onions, peas, and +beans; two to oyster-plants, okra, parsley, and turnips; two to +tomatoes; then four on the other side can be used for strawberries, +blackberries, raspberries, currants, and gooseberries.<span class='pagenum'><a name="Page_236" id="Page_236">[Pg 236]</a></span></p> + +<div class="figcenter"> + <img src="images/img255.jpg" width="500" height="318" + alt="Fig. 224." /><br /> + <b><span class="smcap">Fig. 224. Where Delicious Garden Vegetables +grow</span></b> + </div> + +<p><span class='pagenum'><a name="Page_237" id="Page_237">[Pg 237]</a></span></p> + +<p>The garden, when so arranged, can be tilled in the spring and tended +throughout the growing season with little labor and little loss of time. +In return for this odd-hour work, the farmer's family will have +throughout the year an abundance of fresh, palatable, and health-giving +vegetables and small fruits.</p> + +<p>The keynote of successful gardening is to stir the soil.

GRASSES</h3> + + +<p>Under usual conditions no farmer expects to grow live stock successfully +and economically without setting apart a large part of his land for the +growth of mowing and pasture crops. Therefore to the grower of stock the +management of grass crops is all-important.</p> + +<p>In planting either for a meadow or for a pasture, the farmer should mix +different varieties of grass seeds. Nature mixes them when she plants, +and Nature is always a trustworthy teacher.</p> + +<p>In planting for a pasture the aim should be to sow such seeds as will +give green grass from early spring to latest fall. In seeding for a +meadow such varieties should be sowed together as ripen about the same +time.</p> + +<p>Even in those sections of the country where it grows sparingly and where +it is easily crowded out, clover should be mixed with all grasses sowed, +for it leaves in the soil a wealth of plant food for the grasses coming +after it to feed on. Nearly every part of our country has some clover +that experience shows to be exactly suited to its soil and climate. +Study these clovers carefully and mix them with your grass seed.</p> + +<p>The reason for mixing clover and grass is at once seen. The true +grasses, so far as science now shows, get all their<span class='pagenum'><a name="Page_239" id="Page_239">[Pg 239]</a></span> nitrogen from the +soil; hence they more or less exhaust the soil. But, as several times +explained in this book, the clovers are legumes, and all legumes are +able by means of the bacteria that live on their roots to use the free +nitrogen of the air. Hence without cost to the farmer these clovers help +the soil to feed their neighbors, the true grasses. For this reason some +light perennial legume should always be added to grass seed.</p> + +<div class="figright"> + <img src="images/img258.jpg" width="237" height="300" + alt="Fig. 226." /><br /> + <b><span class="smcap">Fig. 226. Single Plant of Giant Millet</span></b> + </div> + +<p>It is not possible for grasses to do well in a soil that is full of +weeds. For this reason it is always best to sow grass in fields from +which cultivated crops have just been taken. Soil which is to have grass +sowed in it should have its particles pressed together. The small grass +seeds cannot take root and grow well in land that has just been plowed +and which, consequently, has its particles loose and comparatively far +apart. On the other hand, land from which a crop of corn or cotton has +just been harvested is in a compact condition. The soil particles are +pressed well together. Such land when mellowed by harrowing makes a +splendid bed for grass seeds. A firm soil draws moisture up<span class='pagenum'><a name="Page_240" id="Page_240">[Pg 240]</a></span> to the +seeds, while a mellow soil acts as a blanket to keep moisture from +wasting into the air, and at the same time allows the heated air to +circulate in the soil.</p> + +<p>In case land has to be plowed for grass-seeding, the plowing should be +done as far as possible in advance of the seeding. Then the plowed land +should be harrowed several times to get the land in a soft, mellow +condition.</p> + +<p>If the seed-bed be carefully prepared, little work on the ground is +necessary after the seeds are sowed. One light harrowing is sufficient +to cover the broadcast seeds. This harrowing should always be done as +soon as the seeds are scattered, for if there be moisture in the soil +the tiny seeds will soon sprout, and if the harrowing be done after +germination is somewhat advanced, the tender grass plants will be +injured.</p> + +<p>There are many kinds of pasture and meadow grasses. In New England, +timothy, red clover, and redtop are generally used for the mowing crop. +For permanent pasture, in addition to those mentioned, there should be +added white clover and either Kentucky or Canadian blue grass. In the +Southern states a good meadow or pasture can be made of orchard grass, +red clover, and redtop. For a permanent pasture in the South, Japan +clover, Bermuda, and such other local grasses as have been found to +adapt themselves readily to the climate should be added. In the Middle +States temporary meadows and pastures are generally made of timothy and +red clover, while for permanent pastures white clover and blue grass +thrive well. In the more western states the grasses previously suggested +are readily at home. Alfalfa is proving its adaptability to nearly all +sections and climates, and is in many respects the most promising grass +crop of America.<span class='pagenum'><a name="Page_241" id="Page_241">[Pg 241]</a></span></p> + +<div class="figcenter"> + <img src="images/img260.jpg" width="500" height="332" + alt="Fig. 227." /><br /> + <b><span class="smcap">Fig. 227. Bermuda</span></b> + </div> + +<p><span class='pagenum'><a name="Page_242" id="Page_242">[Pg 242]</a></span></p> + +<p>It hardly ever pays to pasture meadows, except slightly, the first +season, and then only when the soil is dry. It is also poor policy to +pasture any kind of grass land early in the spring when the soil is wet, +because the tramping of animals crushes and destroys the crowns of the +plants. After the first year the sward becomes thicker and tougher, and +the grass is not at all injured if it is grazed wisely.</p> + +<div class="figcenter"> + <img src="images/img261.jpg" width="400" height="260" + alt="Fig. 228." /><br /> + <b><span class="smcap">Fig. 228. Alfalfa the Wonderful</span><br />The first crop of the season is being cut and stored for winter</b> + </div> + + +<p>The state of maturity at which grass should be harvested to make hay of +the best quality varies somewhat with the different grasses and with the +use which is to be made of the hay. Generally speaking, it is a good +rule to cut grass for hay just as it is beginning to bloom or just after +the bloom has fallen. All grasses become less palatable to stock as they +mature and form seed. If grass be allowed to go to seed, most of the +nutrition in the stalk is used to form the seed.<span class='pagenum'><a name="Page_243" id="Page_243">[Pg 243]</a></span></p> + +<div class="figcenter"> + <img src="images/img262.jpg" width="400" height="260" + alt="Fig. 229." /><br /> + <b><span class="smcap">Fig. 229. Harvesting Alfalfa</span></b> + </div> +<p><span class='pagenum'><a name="Page_244" id="Page_244">[Pg 244]</a></span></p> + +<p>Hence a good deal of food is lost by waiting to cut hay until the seeds +are formed.</p> + +<p>Pasture lands and meadow lands are often greatly improved by replowing +and harrowing in order to break up the turf that forms and to admit air +more freely into the soil. The plant-roots that are destroyed by the +plowing or harrowing make quickly available plant food by their decay, +and the physical improvement of the soil leads to a thicker and better +stand. In the older sections of the country commercial fertilizer can be +used to advantage in producing hay and pasturage. If, however, clover +has just been grown on grass land or if it is growing well with the +grass, there is no need to add nitrogen. If the grass seems to lack +sufficient nourishment, add phosphoric acid and potash. However, grass +not grown in company with clover often needs dried blood, nitrate of +soda, or some other nitrogen-supplying agent. Of course it is understood +that no better fertilizer can be applied to grass than barnyard manure.</p> + + +<h3>SECTION LII. LEGUMES</h3> + +<p>Often land which was once thought excellent is left to grow up in weeds. +The owner says that the land is worn out, and that it will not pay to +plant it. What does "worn out" mean? Simply that constant cropping has +used up the plant food in the land. Therefore, plants on worn-out land +are too nearly starved to yield bountifully. Such wearing out is so +easily prevented that no owner ought ever to allow his land to become +poverty-stricken. But in case this misfortune has happened, how can the +land be again made fertile?</p> + +<p>On page 24 you learned that phosphoric acid, potash, and nitrogen are +the foods most needed by plants. "Worn out,"<span class='pagenum'><a name="Page_246" id="Page_246">[Pg 246]</a></span><span class='pagenum'><a name="Page_245" id="Page_245">[Pg 245]</a></span> then, to put it in +another way, usually means that a soil has been robbed of one of these +plant necessities, or of two or of all three. To make the land once more +fruitful it is necessary to restore the missing food or foods. How can +this be done? Two of these plant foods, namely, phosphoric acid and +potash, are minerals. If either of these is lacking, it can be supplied +only by putting on the land some fertilizer containing the missing food. +Fortunately, however, nitrogen, the most costly of the plant foods, can +be readily and cheaply returned to poor land.</p> + +<div class="figcenter"> + <img src="images/img264.jpg" width="500" height="293" + alt="Fig. 230." /><br /> + <b><span class="smcap">Fig. 230. Alfalfa ready for the Third Cutting</span></b> + </div> + +<p>As explained on page <a href='#Page_32'><b>32</b></a> the leguminous crops have the power of drawing +nitrogen from the air and, by means of their root-tubercles, of storing +it in the soil. Hence by growing these crops on poor land the expensive +nitrogen is quickly restored to the soil, and only the two cheaper plant +foods need be bought. How important it is then to grow these leguminous +plants! Every farmer should so rotate his planting that at least once +every two or three years a crop of legumes may add to the fruitfulness +of his fields.</p> + +<p>Moreover these crops help land in another way. They send a multitude of +roots deep into the ground. These roots loosen and pulverize the soil, +and their decay, at the end of the growing season, leaves much humus in +the soil. Land will rarely become worn out if legumes are regularly and +wisely grown.</p> + +<p>From the fact that they do well in so many different sections and in so +many different climates, the following are the most useful legumes: +alfalfa, clovers, cowpeas, vetches, and soy beans.</p> + +<p><b>Alfalfa.</b> Alfalfa is primarily a hay crop. It thrives in the Far West, +in the Middle West, in the North, and in the South. In fact, it will do +well wherever the soil is rich, moist, deep, and underlaid by an open +subsoil. The vast areas given<span class='pagenum'><a name="Page_247" id="Page_247">[Pg 247]</a></span> to this valuable crop are yearly +increasing in every section of the United States. Alfalfa, however, +unlike the cowpea, does not take to poor land. For its cultivation, +therefore, good fertile land that is moist but not water-soaked should +be selected.</p> + +<div class="figright"> + <img src="images/img266.jpg" width="350" height="345" + alt="Fig. 231." /><br /> + <b><span class="smcap">Fig. 231.

Second, being a legume, it improves the +soil. Third, one seeding lasts a long time. This length of life may, +however, be destroyed by pasturing or abusing the alfalfa.</p> + + + +<p>Alfalfa is different from most plants in this respect: the soil in which +it grows must have certain kinds of bacteria in it. These cause the +growth of tubercles on the roots. These bacteria, however, are not +always present in land that has not been planted in alfalfa. Hence if +this plant is to be grown successfully these helpful bacteria must +sometimes be supplied artificially.</p> + +<p>There are two very easy ways of supplying the germs. First, fine soil +from an alfalfa field may be scattered broadcast over the fields to be +seeded. Second, a small mass of alfalfa tubercle germs may be put into a +liquid containing proper food to make these germs multiply and grow; +then<span class='pagenum'><a name="Page_248" id="Page_248">[Pg 248]</a></span> the seeds to be planted are soaked in this liquid in order that +the germs may fasten on the seeds.</p> + +<p>Before the seeds are sowed the soil should be mellowed. Over this +well-prepared land about twenty pounds of seed to the acre should be +scattered. The seed may be scattered by hand or by a seed-sower. Cover +with a light harrow. The time of planting varies somewhat with the +climate. Except where the winters are too severe the seed may be sowed +either in the spring or in the fall. In the South sow only in the fall.</p> + +<div class="figcenter"> + <img src="images/img267.jpg" width="500" height="246" + alt="Fig. 232." /><br /> + <b><span class="smcap">Fig. 232. Herd of Dairy Cattle grazing on Alfalfa +Stubble</span></b> + </div> + + + +<p>During the first season one mowing, perhaps more, is necessary to insure +a good stand and also to keep down the weeds. When the first blossoms +appear in the early summer, it is time to start the mower. After this +the alfalfa should be cut every two, three, or four weeks. The number of +times depends on the rapidity of growth.</p> + +<p>This crop rarely makes a good yield the first year, but if a good stand +be secured, the yield steadily increases. After a good stand has been +secured, a top-dressing of either commercial fertilizer or stable manure +will be very helpful. An occasional cutting-up of the sod with a disk +harrow does much good.<span class='pagenum'><a name="Page_249" id="Page_249">[Pg 249]</a></span></p> + +<p><b>Clovers.</b> The different kinds of clovers will sometimes grow on hard or +poor soil, but they do far better if the soil is enriched and properly +prepared before the seed is sowed. In many parts of our country it has +been the practice for generations to sow clover seed with some of the +grain crops. Barley, wheat, oats, and rye are the crops with which +clover is usually planted, but many good farmers now prefer to sow the +seed only with other grass seed. Circumstances must largely determine +the manner of seeding.</p> + +<p>Crimson clover, which is a winter legume, usually does best when seeded +alone, although rye or some other grain often seems helpful to it. This +kind of clover is an excellent crop with which to follow cotton or corn. +It is most conveniently sowed at the last cultivation of these crops.</p> + +<p>Common red clover, which is the standard clover over most of the +country, is usually seeded with timothy or with orchard grass or with +some other of the grasses. In sowing both crimson and red clover, about +ten to fifteen pounds of seed for each acre are generally used.</p> + +<p>To make good pastures, white and Japan clover are favorites. White +clover does well in most parts of America, and Japan clover is +especially valuable in warm Southern climates. Both will do well even +when the soil is partly shaded, but they do best in land fully open to +the sun.</p> + +<p>Careful attention is required to cure clover hay well. The clover should +always be cut before it forms seed. The best time to cut is when the +plants are in full bloom.</p> + +<div class="figcenter"> + <img src="images/img269.jpg" width="320" height="500" + alt="Fig. 233." /><br /> + <b><span class="smcap">Fig. 233. Crimson Clover</span></b> + </div> + +<p>Let the mower be started in the morning. Then a few hours later run over +the field with the tedder. This will loosen the hay and let in air and +sunshine. If the weather be fair let the hay lie until the next day, and +then rake it into rows for further drying. After being raked, the hay +may either be left<span class='pagenum'><a name="Page_250" id="Page_250">[Pg 250]</a></span> <span class='pagenum'><a name="Page_251" id="Page_251">[Pg 251]</a></span>in the rows for final curing or it may be put in +cocks. If the weather be unsettled, it is best to cock the hay. Many +farmers have cloth covers to protect the cocks and these often aid +greatly in saving the hay crop in a rainy season. In case the hay is put +in cocks, it should be opened for a final drying before it is housed.</p> + +<p><b>Cowpeas.</b> The cowpea is an excellent soil-enricher. It supplies more +fertilizing material to turn into the soil, in a short time and at small +cost, than any other crop. Moreover, by good tillage and by the use of a +very small amount of fertilizer, the cowpea can be grown on land too +poor to produce any other crop. Its roots go deep into the soil. Hence +they gather plant food and moisture that shallow-rooted plants fail to +reach. These qualities make it an invaluable help in bringing worn-out +lands back to fertility.</p> + +<p>The cowpea is a warm-weather legume. In the United States it succeeds +best in the south and southwest. It has, however, in recent years been +grown as far north as Massachusetts, New York, Ohio, Michigan, and +Minnesota, but in these cold climates other legumes are more useful. +Cowpeas should never be planted until all danger of frost is past. Some +varieties make their full growth in two months; others need four months.</p> + +<p>There are about two hundred varieties of cowpeas. These varieties differ +in form, in the size of seed and of pod, in the color of seed and of +pod, and in the time of ripening. They differ, too, in the manner of +growth. Some grow erect; others sprawl on the ground. In selecting +varieties it is well to choose those that grow straight up, those that +are hardy, those that fruit early and abundantly, and those that hold +their leaves. The variety selected for seed should also suit the land +and the climate.<span class='pagenum'><a name="Page_252" id="Page_252">[Pg 252]</a></span></p> + +<p>The cowpea will grow in almost any soil. It thrives best and yields most +bountifully on well-drained sandy loams. The plant also does well on +clay soils. On light, sandy soils a fairly good crop may be made, but on +such soils, wilt and root-knot are dangerous foes. A warm, moist, +well-pulverized seed-bed should always be provided. Few plants equal the +cowpea in repaying careful preparation.</p> + +<div class="figcenter"> + <img src="images/img271.jpg" width="400" height="274" + alt="Fig. 234." /><br /> + <b><span class="smcap">Fig. 234. Cowpeas</span></b> + </div> + +<p>If this crop is grown for hay, the method of seeding and cultivating +will differ somewhat from the method used when a seed crop is desired. +When cowpeas are planted for hay the seeds should be drilled or +broadcasted. If the seeds are small and the land somewhat rich, about +four pecks should be sowed on each acre. If the seeds are comparatively +large and the soil not so fertile, about six pecks should be sowed to +the acre. It is safer to disk in the seeds when they are sowed broadcast +than it is to rely on a harrow to cover them. In<span class='pagenum'><a name="Page_253" id="Page_253">[Pg 253]</a></span> sowing merely for a +hay crop, it is a good practice to mix sorghum, corn, soy beans, or +millet with the cowpeas. The mixed hay is more easily harvested and more +easily cured than unmixed cowpea hay. Shortly after seeding, it pays to +run over the land lightly with a harrow or a weeder in order to break +any crust that may form.</p> + +<p>Mowing should begin as soon as the stalks and the pods have finished +growing and some of the lower leaves have begun to turn yellow. An +ordinary mower is perhaps the best machine for cutting the vines. If +possible, select only a bright day for mowing and do not start the +machine until the dew on the vines is dried. Allow the vines to remain +as they fell from the mower till they are wilted; then rake them into +windrows. The vines should generally stay in the windrows for two or +three days and be turned on the last day. They should then be put in +small, airy piles or piled around a stake that has crosspieces nailed to +it. The drying vines should never be packed; air must circulate freely +if good hay is to be made. As piling the vines around stakes is somewhat +laborious, some growers watch the curing carefully and succeed in +getting the vines dry enough to haul directly from the windrows to the +barns. Never allow the vines to stay exposed to too much sunshine when +they are first cut. If the sun strikes them too strongly, the leaves +will become brittle and shatter when they are moved.</p> + +<p>When cowpeas are grown for their pods to ripen, the seeds should be +planted in rows about a yard apart. From two to three pecks of seeds to +an acre should be sufficient. The growing plants should be cultivated +two or three times with a good cultivator. Cowpeas were formerly +gathered by hand, but such a method is of course slow and expensive. +Pickers are now commonly used.<span class='pagenum'><a name="Page_254" id="Page_254">[Pg 254]</a></span></p> + +<p>Some farmers use the cowpea crop only as a soil-enricher. Hence they +neither gather the seeds nor cut the hay, but plow the whole crop into +the soil. There is an average of about forty-seven pounds of nitrogen in +each ton of cowpea vines. Most of this valuable nitrogen is drawn by the +plants from the air. This amount of nitrogen is equal to that contained +in 9500 pounds of stable manure. In addition each ton of cowpea vines +contains ten pounds of phosphoric acid and twenty-nine pounds of potash.</p> + +<p>There is danger in plowing into the soil at one time any bountiful green +crop like cowpeas. As already explained on page 10,[**ref] a process +called capillarity enables moisture to rise in the soil as plants need +it. Now if a heavy cowpea crop or any other similar crop be at one +plowing turned into the soil, the soil particles will be so separated as +to destroy capillarity. Too much vegetation turned under at once may +also, if the weather be warm, cause fermentation to set in and "sour the +land." Both of these troubles may be avoided by cutting up the vines +with a disk harrow or other implement before covering them.</p> + +<p>The custom of planting cowpeas between the rows at the last working of +corn is a good one, and wherever the climate permits this custom should +be followed.</p> + +<p><b>Vetches.</b> The vetches have been rapidly growing in favor for some +years. Stock eat vetch hay greedily, and this hay increases the flow of +milk in dairy animals and helps to keep animals fat and sleek. Only two +species of vetch are widely grown. These are the tare, or spring vetch, +and the winter, or hairy, vetch. Spring vetch is grown in comparatively +few sections of our country. It is, however, grown widely in England and +northern continental Europe. What we say here will be confined to hairy +vetch.<span class='pagenum'><a name="Page_255" id="Page_255">[Pg 255]</a></span></p> + +<p>After a soil has been supplied with the germs needed by this plant, the +hairy vetch is productive on many different kinds of soil. The plant is +most vigorous on fertile loams. By good tillage and proper fertilization +it may be forced to grow rather bountifully on poor sandy and clay +loams. Acid or wet soils are not suited to vetch. Lands that are too +poor to produce clovers will frequently yield fair crops of vetch. If +this is borne in mind, many poor soils may be wonderfully improved by +growing on them this valuable legume.</p> + +<div class="figcenter"> + <img src="images/img274.jpg" width="400" height="284" + alt="Fig. 235." /><br /> + <b><span class="smcap">Fig. 235. Vetch</span></b> + </div> + + +<p>Vetch needs a fine well-compacted seed-bed, but it is often sowed with +good results on stubble lands and between cotton and corn rows, where it +is covered by a cultivator or a weeder.</p> + +<p>The seeds of the vetch are costly and are brought chiefly from Germany, +where this crop is much prized. The pods ripen so irregularly that they +have to be picked by hand.<span class='pagenum'><a name="Page_256" id="Page_256">[Pg 256]</a></span></p> + +<p>In northern climates early spring sowing is found most satisfactory. In +southern climates the seeding is best done in the late summer or early +fall. As the vetch vines have a tendency to trail on the ground, it is +wisest to plant with the vetch some crop like oats, barley, rye, or +wheat. These plants will support the vetch and keep its vines from being +injured by falling on the ground. Do not use rye with vetch in the +South. It ripens too early to be of much assistance. If sowed with oats +the seeding should be at the rate of about twenty or thirty pounds of +vetch and about one and a half or two bushels of oats to the acre. Vetch +is covered in the same way as wheat and rye.</p> + +<p>Few crops enrich soil more rapidly than vetch if the whole plant is +turned in. It of course adds nitrogen to the soil and at the same time +supplies the soil with a large amount of organic matter to decay and +change to humus. As the crop grows during the winter, it makes an +excellent cover to prevent washing. Many orchard-growers of the +Northwest find vetch the best winter crop for the orchards as well as +for the fields.</p> + +<p><b>Soy, or Soja, Bean.</b> In China and Japan the soy bean is grown largely +as food for man. In the United States it is used as a forage plant and +as a soil-improver. It bids fair to become one of the most popular of +the legumes. Like the cowpea, this bean is at home only in a warm +climate. Some of the early-ripening varieties have, however, been +planted with fair success in cold climates.</p> + +<p>While there are a large number of varieties of the soy bean, only about +a dozen are commonly grown. They differ mainly in the color, size, and +shape of the seeds, and in the time needed for ripening. Some of the +varieties are more hairy than others.<span class='pagenum'><a name="Page_257" id="Page_257">[Pg 257]</a></span></p> + +<p>Soy beans may take many places in good crop-rotations, but they are +unusually valuable in short rotations with small grains. The grains can +be cut in time for the beans to follow them, and in turn the beans can +be harvested in the early fall and make way for another grain crop.</p> + +<p>It should always be remembered that soy beans will not thrive unless the +land on which they are to grow is already supplied, or is supplied at +the time of sowing, with bean bacteria.</p> + +<div class="figcenter"> + <img src="images/img276.jpg" width="400" height="285" + alt="Fig. 236." /><br /> + <b><span class="smcap">Fig. 236. Chinese Soy Beans</span></b> + </div> + + +<p>The plant will grow on many different kinds of soil, but it needs a +richer soil than the cowpea does. As the crop can gather most of its own +nitrogen, it generally requires only the addition of phosphoric acid and +potash for its growth on poor land. When the first crop is seeded, apply +to each acre four hundred pounds of a fertilizing mixture which contains +about ten per cent of phosphoric acid, four per cent of potash, and from +one to two per cent of nitrogen.<span class='pagenum'><a name="Page_258" id="Page_258">[Pg 258]</a></span></p> + +<p>If the crop is planted for hay or for grazing, mellow the ground well, +and then broadcast or drill in closely about one and a half bushels of +seed to each acre. Cover from one to two inches deep, but never allow a +crust to form over the seed, for the plant cannot break through a crust +well. When the beans are planted for seeds, a half bushel of seed to the +acre is usually sufficient. The plants should stand in the rows from +four to six inches apart, and the rows should be from thirty to forty +inches from one another. Never plant until the sun has thoroughly warmed +the land. The bean may be sowed, however, earlier than cowpeas. A most +convenient time is just after corn is planted. The rows should be +cultivated often enough to keep out weeds and grass and to keep a good +dust mulch, but the cultivation must be shallow.</p> + +<div class="figcenter"> + <img src="images/img277.jpg" width="400" height="278" + alt="Fig. 237." /><br /> + <b><span class="smcap">Fig. 237. Soy Beans</span></b> + </div> + +<p>As soy beans are grown for hay and also for seed, the harvesting will, +as with the other legumes, be controlled by the<span class='pagenum'><a name="Page_259" id="Page_259">[Pg 259]</a></span> purpose for which the +crop was planted. In harvesting for a hay crop it is desirable to cut +the beans after the pods are well formed but before they are fully +grown. If the cutting is delayed until the pods are ripe, the fruit will +shatter badly. There is a loss, too, in the food value of the stems if +the cutting is late. The ordinary mowing-machine with a rake attached is +generally the machine used for cutting the stalks. The leaves should be +most carefully preserved, for they contain much nourishment for stock.</p> + +<div class="figcenter"> + <img src="images/img278.jpg" width="500" height="338" + alt="Fig. 238." /><br /> + <b><span class="smcap">Fig. 238.

A slight amount of dampness on the plants +aids the cutting. The threshing may be done with a flail, with +pea-hullers, or with a grain-threshing machine.<span class='pagenum'><a name="Page_260" id="Page_260">[Pg 260]</a></span></p> + +<p>The beans produce more seed to the acre than cowpeas do.

The general rule is, poor +stock, poor people. All the prosperous nations of the globe, especially +the grain-growing nations, get a large share of their wealth from +raising improved stock. The stock bred by these nations is now, however, +very different from the stock raised by the same nations years ago. As +soon as man began to progress in the art of agriculture he became +dissatisfied with inferior stock. He therefore bent his energies to +raise the standard of excellence in domestic animals.</p> + +<p>By slow stages of animal improvement the ugly, thin-flanked wild boar of +early times has been transformed into the sleek Berkshire or the +well-rounded Poland-China. In the same manner the wild sheep of the Old +World have been developed into wool and mutton breeds of the finest +excellence. By constant care, attention, and selection the thin, +long-legged wild ox has been bred into the bounteous milk-producing +Jerseys and Holsteins or into the Shorthorn mountains of flesh. From the +small, bony, coarse, and shaggy horse of ancient times have descended +the heavy Norman, or Percheron, draft horse and the fleet Arab courser.</p> + +<p>The matter of meat-production is one of vital importance to the human +race, for animal food must always supply a large part of man's ration.<span class='pagenum'><a name="Page_262" id="Page_262">[Pg 262]</a></span></p> + +<p>Live stock of various kinds consume the coarser foods, like the grasses, +hays, and grains, which man cannot use. As a result of this consumption +they store in their bodies the exact substances required for building up +the tissues of man's body.</p> + +<p>When the animal is used by man for food, one class of foods stored away +in the animal's body produces muscle; another produces fat, heat, and +energy. The food furnished by the slaughter of animals seems necessary +to the full development of man. It is true that the flesh of an animal +will not support human life so long as would the grain that the animal +ate while growing, but it is also true that animal food does not require +so much of man's force to digest it. Hence the use of meat forces a part +of man's life-struggle on the lower animal.</p> + +<p>When men feed grain to stock, the animals receive in return power and +food in their most available forms. Men strengthen the animal that they +themselves may be strengthened. One of the great questions, then, for +the stock-grower's consideration is how to make the least amount of food +fed to animals produce the most power and flesh.</p> + + +<h3>SECTION LIII. HORSES</h3> + +<p>While we have a great many kinds of horses in America, horses are not +natives of this country. Just where wild horses were first tamed and +used is not certainly known. It is believed that in early ages the horse +was a much smaller animal than it now is, and that it gradually attained +its present size. Where food was abundant and nutritious and the climate +mild and healthful, the early horses developed large frames and heavy +limbs and muscles; on the other hand, where food<span class='pagenum'><a name="Page_263" id="Page_263">[Pg 263]</a></span> was scarce and the +climate cold and bleak, the animals remained as dwarfed as the ponies of +the Shetland Islands.</p> + +<div class="figcenter"> + <img src="images/img282.jpg" width="400" height="321" + alt="Fig. 239." /><br /> + <b><span class="smcap">Fig. 239.

The Greeks at first drove the horse +fastened to a rude chariot; later they rode on its back, learning to +manage the animal with voice or switch and without either saddle or +bridle. This thinking people soon invented the snaffle bit, and both +rode and drove with its aid. The curb bit was a Roman invention. Shoeing +was not practiced by either Greeks or Romans. Saddles and harnesses were +at first made of skins and sometimes of cloth.<span class='pagenum'><a name="Page_264" id="Page_264">[Pg 264]</a></span></p> + +<p>Among the Tartars of middle and northern Asia and also among some other +nations, mare's milk and the flesh of the horse are used for food. Old +and otherwise worthless horses are regularly fattened for the meat +markets of France and Germany. Various uses are made of the different +parts of a horse's body. The mane and tail are used in the manufacture +of mattresses, and also furnish a haircloth for upholstering; the skin +is tanned into leather; the hoofs are used for glue, and the bones for +making fertilizer.</p> + +<div class="figcenter"> + <img src="images/img283.jpg" width="400" height="350" + alt="Fig. 240." /><br /> + <b><span class="smcap">Fig. 240.

This is shown in Figs. 248, 249. The beef cow is square, +full over the back and loins, and straight in the back. The hips are +covered evenly with flesh, the legs full and thick, the under line, or +stomach line, parallel to the back line, and the neck full and short. +The eye should be bright, the face short, the bones of fine texture, and +the skin soft and pliable.</p> + +<div class="figcenter"> + <img src="images/img291.jpg" width="400" height="325" + alt="Fig. 248." /><br /> + <b><span class="smcap">Fig. 248. Aberdeen-Angus Cow (a Beef Type)</span></b> + </div> + +<p>The dairy cow is widely different from the beef cow. She shows a decided +wedge shape when you look at her from front, side, or rear. The back +line is crooked, the hip bones and tail bone are prominent, the thighs +thin and poorly fleshed; there is no breadth to the back, as in the beef +cow, and little flesh covers the shoulders; the neck is long and thin.<span class='pagenum'><a name="Page_273" id="Page_273">[Pg 273]</a></span></p> + +<p>The udder of the dairy cow is most important. It should be full but not +fleshy, be well attached behind, and extend well forward. The larger the +udder the more milk will be given.</p> + +<p>The skin of the dairy cow, like that of the beef breeds, should be soft +and pliable and the bones fine-textured.</p> + +<p><b>The Dairy Type.</b> Because of lack of flesh on the back, loins, and +thighs, the cow of the dairy type is not profitably raised for beef, nor +is the beef so good as that of the beef types. This is because in the +dairy-animal food goes to produce milk rather than beef. In the same way +the beef cow gives little milk, since her food goes rather to fat than +to milk. For the same reasons that you do not expect a plow horse to win +on the race track, you do not expect a cow of the beef type to win +premiums as a milker.</p> + +<div class="figcenter"> + <img src="images/img292.jpg" width="400" height="265" + alt="Fig. 249." /><br /> + <b><span class="smcap">Fig. 249. Jersey Cow (a Dairy Type)</span></b> + </div> + +<p>"Scrub" cattle are not profitable. They mature slowly and consequently +consume much food before they are able to give any return for it. Even +when fattened, the fat and<span class='pagenum'><a name="Page_274" id="Page_274">[Pg 274]</a></span> lean portions are not evenly distributed, +and "choice cuts" are few and small.</p> + +<p>By far the cheapest method of securing a healthy and profitable herd of +dairy or beef cattle is to save only the calves whose sires are +pure-bred animals and whose mothers are native cows. In this way farmers +of even little means can soon build up an excellent herd.</p> + +<div class="figleft"> + <img src="images/img293.jpg" width="281" height="300" + alt="Fig. 250." /><br /> + <b><span class="smcap">Fig. 250. Head of a Galloway Cow</span></b> + </div> + +<p><b>Improving Cattle.</b> The fact that it is not possible for every farmer to +possess pure-bred cattle is no reason why he should not improve the +stock he has. He can do this by using pure-bred sires that possess the +qualities most to be desired. Scrub stock can be quickly improved by the +continuous use of good sires. It is never wise to use grade, or +cross-bred, sires, since the best qualities are not fixed in them.</p> + + +<p>Moreover, it is possible for every farmer to determine exactly the +producing-power of his dairy cows. When the cows are milked, the milk +should be weighed and a record kept. If this be done, it will be found +that some cows produce as much as five hundred, and some as much as ten +hundred, gallons a year, while others produce not more than two or three +hundred gallons. If a farmer kills or sells his poor cows and keeps his +best ones, he will soon have a herd of only heavy milkers. Ask your +father to try this plan. Read everything you can find about taking care +of cows and improving them, and then start a herd of your own.<span class='pagenum'><a name="Page_275" id="Page_275">[Pg 275]</a></span></p> + +<p><b>Conclusions.</b> (1) A cow with a tendency to get fat is not profitable +for the dairy. (2) A thin, open, angular cow will make expensive beef. +(3) "The sire is half the herd." This means that a good sire is +necessary to improve a herd of cattle. The improvement from scrubs +upward is as follows: the first generation is one-half pure; the second +is three-fourths pure; the third is seven-eighths pure; the fourth is +fifteen-sixteenths pure, etc. (4) By keeping a record of the quantity +and quality of milk each cow gives you can tell which are profitable to +raise from and which are not. (5) Good food, clean water, kindness, and +care are necessary to successful cattle-raising.</p> + +<div class="figcenter"> + <img src="images/img294.jpg" width="400" height="251" + alt="Fig. 251." /><br /> + <b><span class="smcap">Fig. 251.

BEE CULTURE</h3> + +<p>Stock-raisers select breeds that are best adapted to their needs. +Plant-growers exercise great care in their choice of plants, selecting +for each planting those best suited to the conditions under which they +are to be grown. Undoubtedly a larger yield of honey could be had each +year if similar care were exercised in the selection of the breed of +bees.</p> + +<div class="figleft"> + <img src="images/img307.jpg" width="150" height="125" + alt="Fig. 263." /><br /> + <b><span class="smcap">Fig. 263. A Carniolan Worker</span></b> + </div> + +<p>To prove this, one has only to compare the yield of two different kinds. +The common East Indian honey bee rarely produces more than ten or twelve +pounds to a hive, while the Cyprian bee, which is a most industrious +worker, has a record of one thousand pounds in one season from a single +colony. This bee, besides being industrious when honey material is +plentiful, is also very persevering when such material is hard to find. +The Cyprians have two other very desirable qualities. They<span class='pagenum'><a name="Page_287" id="Page_287">[Pg 287]</a></span> stand the +cold of winter well and stoutly defend their hives against robber bees +and other enemies.</p> + +<p>The Italian is another good bee. This variety was brought into the +United States in 1860. While the yield from the Italian is somewhat less +than from the Cyprian, the Italian bees produce a whiter comb and are a +trifle more easily managed.</p> + +<p>The common black or brown bee is found wild and domesticated throughout +the country. When honey material is abundant, these bees equal the +Italians in honey-production, but when the season is poor, they fall far +short in the amount of honey produced.</p> + +<p>The purchase of a good Cyprian or Italian hive will richly repay the +buyer.

A Carniolan Drone</span></b> + </div> + +<p>A beehive in the spring contains one queen, several hundred drones, and +from thirty-five to forty thousand workers. The duty of the queen is to +lay all the eggs that are to hatch the future bees. This she does with +untiring industry, often laying as many as four thousand in twenty-four +hours.</p> + +<p>The worker bees do all the work. Some of them visit the flowers, take up +the nectar into the honey-sac, located in their abdomens, and carry it +to the hive. They also gather pollen in basketlike cavities in their +hind legs. Pollen and nectar are needed to prepare food for the young +bees. In<span class='pagenum'><a name="Page_288" id="Page_288">[Pg 288]</a></span> the hive other workers create a breeze by buzzing with their +wings and produce heat by their activity—all to cause the water to +evaporate from the nectar and to convert it into honey before it is +sealed up in the comb. After a successful day's gathering you may often +hear these tireless workers buzzing till late into the night or even all +through the night.</p> + +<div class="figleft"> + <img src="images/img309.jpg" width="143" height="150" + alt="Fig. 265." /><br /> + <b><span class="smcap">Fig. 265.

The yield of honey may often be increased +by providing special pasturage for the bees. The linden tree, for +example, besides being ornamental and valuable for timber, produces a +most bee-inviting flower. Vetch, clover, and most of the legumes and +mints are valuable plants to furnish pasture for bees. Catnip may be +cultivated for the bees and sold as an herb as well.</p> + + +<p>In spraying fruit trees to prevent disease you should always avoid +spraying when the trees are in bloom, since the poison of the spray +seriously endangers the lives of bees.</p> + +<p>The eggs laid by the queen, if they are to produce workers, require +about twenty-one days to bring forth the perfect bee. The newly hatched +bee commences life as a nurse.

Is +the kingbird really an enemy to the bee?</p></div> + +<h3>SECTION LIX. WHY WE FEED ANIMALS</h3> + +<p>In the first place, we give various kinds of feed stuffs to our animals +that they may live. The heart beats all the time, the lungs contract and +expand, digestion is taking place, the blood circulates through the +body—something must supply force for these acts or the animal dies. +This force is derived from food.</p> + +<p>In the next place, food is required to keep the body warm. Food in this +respect is fuel, and acts in the same way that wood or coal does in the +stove. Our bodies are warm all the time, and they are kept warm by the +food we eat at mealtime.</p> + +<p>Then, in the third place, food is required to enable the body to +enlarge—to grow. If you feed a colt just enough to keep it alive and +warm, there will be no material present to enable it to grow; hence you +must add enough food to form bone and flesh and muscle and hair and fat.</p> + +<p>In the fourth place, we feed to produce strength for work. An animal +poorly fed cannot do so much work at the plow or on the road as one that +receives all the food needed.</p> + +<p>Both food and the force produced by it result from the activity of +plants. By means of sunlight and moisture a sprouting seed, taking out +of the air and soil different elements, grows into a plant. Then, just +as the plant feeds on the air and soil to get its growth, so the animal +feeds<span class='pagenum'><a name="Page_291" id="Page_291">[Pg 291]</a></span> on the plant, to get its growth. Hence, since our animals feed +upon plants, we must find out what is in plants in order to know what +animal food consists of.</p> + +<p>Plants contain protein, carbohydrates, fat, mineral matter, water, and +vitamins. You have seen protein compounds like the white of an egg, lean +meat, or the gluten of wheat. The bodies of plants do not contain very +much protein. On the other hand, all plant seeds contain a good deal of +this substance. Animals make use of protein to form new blood, muscles, +and organs. Because of the quality of protein, milk is the best food for +children and young animals.</p> + +<p>The protein in some foods is of poor quality. To insure a well-balanced +supply of protein a variety in foods is desirable. Do not rely on a +single kind of mill feed, but combine several kinds, such as cotton-seed +meal, linseed meal, wheat bran and middlings, gluten, and similar grain +by-products. Tankage for young pigs and meat scraps for chickens are +high-grade proteins and are of animal origin.</p> + +<p>It is no less important to get the necessary vitamins—those mysterious +substances that keep the body healthy and promote growth and well-being. +Scientists claim that many diseases are food-deficiency diseases—the +body gets out of order because these peculiar vitamins are lacking in +the food. Children require about one or two quarts of milk a day, fresh +fruits, cereal breakfast foods, leafy vegetables as salads, and cooked +vegetables.</p> + +<p>Farm animals require the vitamins also. The legume pasture or hay, milk, +grain concentrates when supplied in variety, pasture grass, and green +forage crops are basic foods for farm animals. Very young animals should +have milk also.</p> + +<p>Let us next consider the carbohydrates. Sometimes the words <i>starchy +foods</i> are used to describe the carbohydrates.<span class='pagenum'><a name="Page_292" id="Page_292">[Pg 292]</a></span> You have long known +forms of these in the white material of corn and of potatoes. The +carbohydrates are formed of three elements—carbon, oxygen, and +hydrogen. The use of these carbohydrates is to furnish to animal bodies +either heat or energy or to enable them to store fat.</p> + +<p>In the next place, let us look at the fat in plant food. This consists +of the oil stored up in the seeds and other parts of the plant. The +grains contain most of the oil. Fat is used by the animal to make heat +and energy or to be stored away in the body.</p> + +<p>The next animal food in the plant that we are to think about is the +mineral matter. The ashes of a burnt plant furnish a common example of +this mineral matter. The animal uses this material of the plant to make +bone, teeth, and tissue.</p> + +<p>The last thing that the plant furnishes the animal is water—just common +water. Young plants contain comparatively large quantities of water. +This is one reason why they are soft, juicy, and palatable. But, since +animals get their water chiefly in another way, the water in feed stuffs +is not important.</p> + +<h4><span class="smcap">What these Compounds do in the Body</span></h4> + + + +<div class='centered'> +<table border="0" cellpadding="2" width="75%" cellspacing="0" summary="What these Compounds do in the Body"> +<tr><th align='left'><i>Protein</i></th></tr> +<tr><td align='left'>1.

THE DAIRY COW</h3> + +<p>Success in dairy farming depends largely upon the proper feeding of +stock. There are two questions that the dairy farmer should always ask +himself: Am I feeding as cheaply as I can? and, Am I feeding the best +rations for milk and butter production? Of course cows can be kept alive +and in fairly good milk flow on many different kinds of food, but in +feeding, as in everything else, there is an ideal to be sought.</p> + +<div class="figcenter"> + <img src="images/img314.jpg" width="400" height="254" + alt="Fig. 268." /><br /> + <b><span class="smcap">Fig. 268. Milking-Time</span></b> + </div> +<p><span class='pagenum'><a name="Page_294" id="Page_294">[Pg 194]</a></span></p> + +<p>What, then, is an ideal ration for a dairy cow? Before trying to answer +this question the word <i>ration</i> needs to be explained. By ration is +meant a sufficient quantity of food to support properly an animal for +one day. If the animal is to have a proper ration, we must bear in mind +what the animal needs in order to be best nourished. To get material for +muscle, for blood, for milk, and for some other things, the animal +needs, in the first place, food that contains protein. To keep warm and +fat, the animal must, in the second place, have food containing +carbohydrates and fats. These foods must be mixed in right proportions.</p> + +<div class="figcenter"> + <img src="images/img315.jpg" width="400" height="295" + alt="Fig. 269." /><br /> + <b><span class="smcap">Fig. 269. A Dairy</span></b> + </div> + +<p>With these facts in mind we are prepared for an answer to the question, +What is an ideal ration?</p> + +<p>First, it is a ration that, without waste, furnishes both in weight and +bulk of dry matter a sufficient amount of digestible, nutritious food.<span class='pagenum'><a name="Page_295" id="Page_295">[Pg 295]</a></span></p> + +<p>Second, it is a ration that is comparatively cheap.</p> + +<p>Third, it is a ration in which the milk-forming food (protein) is +rightly proportioned to the heat-making and fat-making food +(carbohydrates and fat). Any ration in which this proportion is +neglected is badly balanced.</p> + +<p>Now test one or two commonly used rations by these rules. Would a ration +of cotton-seed meal and cotton-seed hulls be a model ration? No. Such a +ration, since the seeds are grown at home, would be cheap enough. +However, it is badly balanced, for it is too rich in protein; hence it +is a wasteful ration. Would a ration of corn meal and corn stover be a +desirable ration? This, too, since the corn is home-grown, would be +cheap for the farmer; but, like the other, it is badly balanced, for it +contains too much carbohydrate food and is therefore a wasteful ration.</p> + +<p>A badly balanced ration does harm in two ways: first, the milk flow of +the cow is lessened by such a ration; second, the cow does not +profitably use the food that she eats.</p> + +<p>The following table gives an excellent dairy ration for the farmer who +has a silo. If he does not have a silo, some other food can be used in +place of the ensilage. The table also shows what each food contains.

In this way you will be least likely to waste +food.</p> + +<p>2. Feed at regular hours. Cows, like people, thrive best when their +lives are orderly.</p> + +<p>3. Milk at regular hours.</p> + +<p>4. Brush the udder carefully with a moist cloth before you begin to +milk. Cleanliness in handling makes the milk keep longer.</p> + +<p>5.

MILK, CREAM, CHURNING, AND BUTTER</h3> + +<p><b>Milk.</b> Milk is, as you know, nature's first food for mammals. This is +because milk is a model food—it contains water to slake thirst, ash to +make bone, protein to make flesh and muscle, and fat and sugar to keep +the body warm and to furnish energy.</p> + +<p><b>The Different Kinds of Milk.</b> Whole, or unskimmed, milk, skimmed milk, +and buttermilk are too familiar to need description. When a cow is just +fresh, her milk is called <i>colostrum</i>. Colostrum is rich in the very +food that the baby calf needs. After the calf is a few days old, +colostrum changes to what is commonly known as milk.</p> + +<p>The following table shows the composition of each of the different forms +of milk:</p> + + + + +<div class='centered'> +<table border="0" cellpadding="2" width="70%" cellspacing="0" summary="The following table shows the composition of each of the different forms +of milk"> +<tr><th align='left'>Composition of Milk</th><th colspan="4" align='center'>Digestible Matter in 100 Pounds</th></tr> +<tr><td> </td><th align='right'>Dry matter</th><th align='right'>Protein</th><th align='right'>Carbohydrates</th><th align='right'>Fat</th></tr> +<tr><td align='left'>Colostrum</td><td align='right'>25.4</td><td align='right'>17.6</td><td align='right'>2.7</td><td align='right'>3.6</td></tr> +<tr><td align='left'>Milk (unskimmed)</td><td align='right'>12.8</td><td align='right'>3.6</td><td align='right'>4.9</td><td align='right'>3.7</td></tr> +<tr><td align='left'>Skimmed milk</td><td align='right'>9.4</td><td align='right'>2.9</td><td align='right'>5.2</td><td align='right'>1.3</td></tr> +<tr><td align='left'>Buttermilk</td><td align='right'>9.9</td><td align='right'>3.9</td><td align='right'>4.0</td><td align='right'>1.1</td></tr> +</table></div> + + +<p>A noticeable fact in this table is that skimmed milk differs from +unskimmed mainly in the withdrawal of the fat. Hence, if calves are fed +on skimmed milk, they should have in addition some food like corn meal +to take the place of the fat withdrawn. A calf cannot thrive on skimmed +milk alone. The amount of nourishing fat that a calf gets out of enough +milk to make a pound of butter can be bought, in the form of linseed or +corn meal, for a very small amount, while the<span class='pagenum'><a name="Page_298" id="Page_298">[Pg 298]</a></span> butter-fat costs, for +table use, a much larger sum. Of course, then, it is not economical to +allow calves to use unskimmed milk. Some people undervalue skimmed milk; +with the addition of some fatty food it makes an excellent ration for +calves, pigs, and fowls.</p> +<div class="figleft"> + <img src="images/img321.jpg" width="300" height="256" + alt="Fig. 270." /><br /> + <b><span class="smcap">Fig. 270.

This +property is hard to describe, for its elements and its powers are not +yet fully understood. We do, however, know certainly this much: milk and +the foods made from it have power to promote health and favor growth in +a more marked degree than any other foods. It is generally agreed that +this is due to the health-promoting and health-preserving substances +which are called vitamines. Men of science are working with much care to +try to add to our knowledge of these vitamines, which have so marvelous +an influence on the health of all animals. Unless food, no matter how +good otherwise, contains these vitamines, it does not nourish the body +nor preserve bodily health as it should. A complete lack of vitamines in +our food would cause death. Since, then, milk and its products—butter, +cheese, curds—are rich in vitamines, these health-giving and +health-preserving foods should form a regular part of each person's +diet.</p> + + +<p><span class='pagenum'><a name="Page_299" id="Page_299">[Pg 299]</a></span></p> +<div class="figright"> + <img src="images/img322.jpg" width="216" height="300" + alt="Fig. 271." /><br /> + <b><span class="smcap">Fig. 271. A Hand Separator</span></b> + </div> +<p><b>Cream.</b> Cream is simply a mixture of butter-fat and milk. The +butter-fat floats in the milk in little globe-shaped bodies, or +globules. Since these globules are lighter than milk, they rise to the +surface. Skimming the milk is a mere gathering together of these +butter-fat globules. As most of the butter-fat is contained in the +cream, pains should be taken to get all the cream from the milk at +skimming time.</p> + +<p>After the cream has been collected, it must be allowed to "ripen" or to +"sour" in order that it may be more easily churned.

Do not churn too long, for this spoils butter. As soon as the +granules of butter are somewhat smaller than grains of wheat, stop the +churn. Then draw off the buttermilk and at a temperature as low as 50° +wash the butter in the churn.

Use good fine +dairy salt. Coarse barrel salt is not fit for butter. The salt can be +added while the butter is still in the churn or after it is put upon the +butter-worker. Never work by hand. The object of working is to get the +salt evenly distributed and to drive out some of the brine. It is +usually best to work butter twice. The two workings bring about a more +even mixture of the salt with the butter and drive off more water. But +one cannot be too particular not to overwork butter. Delicate coloring, +attractive stamping with the dairy owner's special stamp, and proper +covering with paper cost little and of course add to the ready and +profitable sale of butter.</p> + + +<p><span class='pagenum'><a name="Page_301" id="Page_301">[Pg 301]</a></span></p> + + +<h3><span class="smcap">Dairy Rules</span></h3> + +<p><i>Stable and Cows</i></p> + +<p>1.

HOW MILK SOURS</h3> + + +<div class="figcenter"> + <img src="images/img325.jpg" width="400" height="194" + alt="Fig. 273." /><br /> + <b><span class="smcap">Fig. 273. Microscopic Appearance of Pure and Impure +Milk</span></b> + </div> + +<blockquote><h4>At the left, pure milk; at the right, milk after standing in a warm room +for a few hours in a dirty dish, showing, besides the fat-globules, many +forms of bacteria</h4></blockquote> + +<p>On another page you have been told how the yeast plant grows in cider +and causes it to sour, and how bacteria sometimes cause disease in +animals and plants. Now you must learn what these same living forms have +to do with the souring of milk, and maybe you will not forget how you +can prevent your milk from souring. In the first place, milk sours +because bacteria from the air fall into the milk, begin to grow, and +very shortly change the sugar of the milk to an acid. When this acid +becomes abundant, the milk begins to curdle. As you know, the bacteria +are in air, in water, and in barn dust; they stick on bits of hay and +stick to the cow. They are most plentiful, however, in milk that has +soured; hence, if we pour a little sour milk into a pail of fresh milk, +the fresh milk will sour very quickly, because we have, so to speak, +"seeded" or "planted" the fresh milk with the souring germs. No one, of +course, ever does this purposely in the dairy, yet people sometimes do +what amounts to the same thing—that is, put fresh milk into poorly +cleaned<span class='pagenum'><a name="Page_303" id="Page_303">[Pg 303]</a></span> pails or pans, the cracks and corners of which are cozy homes +for millions of germs left from the last sour milk contained in the +vessel. It follows, then, that all utensils used in the dairy should be +thoroughly scalded so as to kill all germs present, and particular care +should be taken to clean the cracks and crevices, for in them the germs +lurk.</p> + +<p>In addition to this thorough cleansing with hot water, we should be +careful never to stir up the dust of the barn just before milking. Such +dusty work as pitching hay or stover or arranging bedding should be done +either after or long before milking-time, for more germs fall into the +milk if the air be full of dust.</p> + +<p>To further avoid germs the milker should wear clean overalls, should +have clean hands, and, above all, should never wet his hands with milk. +This last habit, in addition to being filthy, lessens the keeping power +of the milk. The milker should also moisten the parts of the cow which +are nearest him, so that dust from the cow's sides may not fall into the +milker's pail. For greater cleanliness and safety many milkmen curry +their cows.</p> + +<p>The first few streams from each teat should be thrown away, because the +teat at its mouth is filled with milk which, having been exposed to the +air, is full of germs, and will do much toward souring the other milk in +the pail. Barely a gill will be lost by throwing the first drawings +away, and this of the poorest milk too. The increase in the keeping +quality of the milk will much more than repay the small loss. If these +precautions are taken, the milk will keep several hours or even several +days longer than milk carelessly handled. By taking these steps to +prevent germs from falling into the milk, a can of milk was once kept +sweet for thirty-one days.<span class='pagenum'><a name="Page_304" id="Page_304">[Pg 304]</a></span></p> + +<p>The work of the germ in the dairy is not, however, confined to souring +the milk. Certain kinds of germs give to the different sorts of cheeses +their marked flavors and to butter its flavor. If the right germ is +present, cheese or butter gets a proper flavor. Sometimes undesirable +germs gain entrance and give flavors that we do not like. Such germs +produce cheese or butter diseases. "Bitter butter" is one of these +diseases. To keep out all unpleasant meddlers, thoroughly cleanse and +scald every utensil.</p> + +<div class="blockquot"><p><b>EXERCISE</b></p> + +<p>What causes milk to sour?

Why?</p></div> + + +<h3>SECTION LXIII. THE BABCOCK MILK-TESTER</h3> + +<p>It is not sufficient for a farmer or a dairyman to know how much milk +each of his cows yields. He should also know how rich the milk is in +butter-fat. Wide-awake makers of butter and cheese now buy milk, not by +the pound or by the gallon, but by the amount of butter-fat contained in +each pound or gallon of milk. A gallon of milk containing four and a +half per cent of fat will consequently be worth more than a gallon +containing only three per cent of fat. So it may happen that a cow +giving only two gallons of milk may pay a butter-maker more than a cow +giving three gallons of milk. Of course it is easy to weigh or measure +the quantity of milk given by a cow, and most milkers keep this record; +but until recent years there was no way to find out the amount of fat in +a cow's milk except by a slow and costly chemical test. Dairymen could +only guess at the richness of milk.<span class='pagenum'><a name="Page_305" id="Page_305">[Pg 305]</a></span></p> + +<p>In 1890 Dr. S. M. Babcock of the Wisconsin Experiment Station invented a +wonderful little machine that quickly and cheaply measures the fat in +milk. Few machines are more useful. So desirous was Dr. Babcock of +helping the farmers that he would not add to the cost of his machine by +taking out a patent on his invention. His only reward has been the fame +won by the invention of the machine, which bears his name. This most +useful tester is now made in various sizes so that every handler of milk +may buy one suited to his needs and do his own testing at very little +cost.</p> + +<p>The operation of the machine is very simple. Suppose that the members of +the class studying this book have been asked to take a Babcock machine +and test the milk of a small herd of cows. They can readily do so by +following these directions:</p> + +<p>While the milk is still warm from the first cow to be tested, mix it +thoroughly by pouring it at least four times from one vessel to another. +A few ounces of this mixed milk is then taken for a sample, and +carefully marked with the name of the cow. A number is also put on the +sample, and both the cow's name and the number entered in a notebook. A +small glass instrument, called a pipette, comes with each machine. Put +one end of the pipette into the milk sample and the other end into the +mouth. Suck milk into the pipette until the milk comes up to the mark on +the side of the pipette. As soon as the mark is reached, withdraw the +pipette from the mouth and quickly press the forefinger on the mouth +end. The pressure of the finger will keep the milk from running out. +Then put the lower end of the pipette into one of the small long-necked +bottles of the machine, and, lifting the finger, allow the milk to flow +gently into the bottle. Expel all the milk by blowing through the +pipette.<span class='pagenum'><a name="Page_306" id="Page_306">[Pg 306]</a></span></p> + +<p>The next step is to add a strong, biting acid known as sulphuric acid to +the test-bottle into which you have just put the milk. A glass marked to +show just how much acid to use also comes with the machine. Fill this +glass measure to the mark. Then pour the acid carefully into the +test-bottle. Be sure not to drop any of the acid on your hands or your +clothes. As the acid is heavier than the milk, it will sink to the +bottom of the bottle. With a gentle whirling motion, shake the bottle +until the two fluids are thoroughly mixed. The mixture will turn a dark +brown and become very warm.</p> + +<p>Now fill the other bottles in the same way with samples drawn from +different cows. Treat all the samples precisely as you did the first. Do +not forget to put on each sample the name of the cow giving the milk and +on each test-bottle a number corresponding to the name of the cow.</p> + +<p>You are now ready to put the test-bottles in the sockets of the machine. +Arrange the bottles in the sockets so that the whirling frame of the +machine will be balanced. Fit the cover on the machine and turn the +handle slowly. Gradually gain in speed until the machine is whirled +rapidly. Continue the turning for about seven minutes at the speed +stated in the book of directions.</p> + +<p>After this first turning is finished, pour enough hot water into each +test-bottle to cause the fat to rise to the neck of the bottle. Re-cover +the machine and turn for one minute. Again add hot water to each bottle +until all the fat rises into the neck of the bottle and again turn one +minute.</p> + +<p>There remains now only the reading of the record. On the neck of each +bottle there are marks to measure the amount of fat. If the fat inside +the tube reaches only from the lowest mark to the second mark, then +there is only one per cent of fat in this cow's milk. This means that +the owner of the<span class='pagenum'><a name="Page_307" id="Page_307">[Pg 307]</a></span> cow gets only one pound of butter-fat from each +hundred pounds of her milk. Such a cow would not be at all profitable to +a butter-seller. If the fat in another test-bottle reaches from the +lowest mark to the fourth mark, then you put in your record-book that +this cow's milk contains four per cent of butter-fat. This record shows +that the second cow's milk yields four pounds of fat to every hundred +pounds of milk. This cow is three times more valuable to a butter-maker +than the first cow. In the same way add one more per cent for each +higher mark reached by the fat. Four and one-half per cent is a good +record for a cow to make. Some cows yield as high as five or six per +cent but they do not generally keep up this record all the year.</p> + +<div class="figcenter"> + <img src="images/img330.jpg" width="450" height="347" + alt="Fig. 274." /><br /> + <b><span class="smcap">Fig. 274.

This is because butter contains a few other things +in addition to pure butter-fat. Finished and salted butter weighs on an +average about one sixth more than the fat shown by the tester. Hence to +get the exact amount of butter in every 100 pounds of milk, you will +have to add one sixth to the record shown by the tester. Suppose, for +example, you took one sample from 600 pounds of milk and that your test +showed 4 per cent of fat in every 100 pounds of milk. Then, as you had +600 pounds of milk, you would have 24 pounds of butter-fat. This fat, +after it has been salted and after it has absorbed moisture as butter +does, will gain one sixth in weight. As one sixth of 24 is 4, this new 4 +pounds must be added to the weight of the butter-fat. Hence the 600 +pounds of milk would produce about 28 pounds of butter.</p> + +<div class="blockquot"><p><b>EXERCISE</b></p> + +<p>1.

GROWING FEED STUFFS ON THE FARM</h3> + +<p>Economy in raising live stock demands the production of all "roughness" +or roughage materials on the farm. By roughness, or roughage, of course +you understand that bulky food, like hay, grass, clover, stover, etc., +is meant. It is possible to purchase all roughage materials and yet make +a financial success of growing farm animals, but this certainly is not +the surest way to succeed. Every farm should raise all its feed stuffs. +In deciding what forage and grain crops to grow we should decide:</p> + +<p> +<span style="margin-left: 2em;">1.

The crops that will keep our soil in the best condition.</span><br /> +</p> + +<p>1. <i>The crops best suited to our soil and climate.</i> Farm crops, as every +child of the farm knows, are not equally adapted to all soils and +climates. Cotton cannot be produced where the climate is cool and the +seasons short. Timothy and blue grass are most productive on cool, +limestone soils. Cowpeas demand warm, dry soils. But in spite of +climatic limitations, Nature has been generous in the wide variety of +forage she has given us.<span class='pagenum'><a name="Page_310" id="Page_310">[Pg 310]</a></span></p> + +<p>Our aim should be to make the best use of what we have, to improve by +selection and care those kinds best adapted to our soil and climate, and +to secure, by better methods of growing and curing, the greatest yields +at the least possible cost.</p> + +<p>2. <i>The crops best suited to our line of business.</i> A farmer necessarily +becomes more or less of a specialist; he gathers those kinds of live +stock about him which he likes best and which he finds the most +profitable. He should, on his farm, select for his main crops those that +he can grow with the greatest pleasure and with the greatest profit.</p> + +<div class="figcenter"> + <img src="images/img333.jpg" width="450" height="275" + alt="Fig. 275." /><br /> + <b><span class="smcap">Fig. 275.

Should not his past failures<span class='pagenum'><a name="Page_311" id="Page_311">[Pg 311]</a></span> and his past triumphs decide +his future? If he be a dairy farmer, ought he not by practical tests to +settle for himself not only what crops are most at home on his land but +also what crops in his circumstances yield him the largest returns in +milk and butter? If swine-raising be his business, how long ought he to +guess what crop on his land yields him the greatest amount of hog food? +Should a colt be fed on one kind of forage when the land that produced +that forage would produce twice as much equally good forage of another +kind? All these questions the prudent farmer should answer promptly and +in the light of wise experiments.</p> + +<p>3. <i>The crops that will give us the most protein.</i> It is the farmer's +business to grow all the grass and forage that his farm animals need. He +ought never to be obliged to purchase a bale of forage. Moreover, he +should grow mainly those crops that are rich in protein materials, for +example, cowpeas, alfalfa, and clover. If such crops are produced on the +farm, there will be little need of buying so much cotton-seed meal, +corn, and bran for feeding purposes.</p> + +<p>4. <i>The crops that produce the most.</i> We often call a crop a crop +without considering how much it yields. This is a mistake. We ought to +grow, when we have choice of two crops, the one that is the best and the +most productive on the farm. Average corn, for instance, yields on an +acre at least twice the quantity of feeding-material that timothy does.</p> + +<p>5. <i>The crops that will keep our soil in the best condition.</i> A good +farmer should always be thinking of how to improve his soil.

FARM TOOLS AND MACHINES</h3> + +<p>The drudgery of farm life is being lessened from year to year by the +invention or improvement of farm tools and machines. Perhaps some of you +know how tiresome was the old up-and-down churn dasher that has now +generally given place to the "quick-coming" churns. The toothed, +horse-drawn cultivator has nearly displaced "the man with the hoe," +while the scythe, slow and back-breaking, is everywhere getting out of +the way of the mowing-machine and the horserake. The old heavy, +sweat-drawing grain-cradle is slinking into the backwoods, and in its +place we have the horse-drawn or steam-drawn harvester that cuts and +binds the grain, and even threshes and measures it at one operation. +Instead of the plowman's wearily making one furrow at a time, the +gang-plows of the plains cut many furrows at one time, and instead of +walking the plowman rides. The shredder and husker turns the hitherto +useless cornstalk into food, and at the same time husks, or shucks, the +corn.</p> + +<p>The farmer of the future must know three things well: first, what +machines he can profitably use; second, how to manage these machines; +third, how to care for these machines.<span class='pagenum'><a name="Page_313" id="Page_313">[Pg 313]</a></span></p> + +<div class="figcenter"> + <img src="images/img336a.jpg" width="500" height="110" + alt="Fig. 276." /><br /> + <b><span class="smcap">Fig. 276.

As soon as a plow, harrow, cultivator—indeed +any tool or machine—has finished its share of work for the season, it +should receive whatever attention it needs to prevent rusting, and +should be carefully housed.</p> + +<p>Such care, which is neither costly nor burdensome, will add many years +to the life of a machine.</p> + + +<h3>SECTION LXVI. LIMING THE LAND</h3> + +<p>Occasionally, when a cook puts too much vinegar in a salad, the dish +becomes so sour that it is unfit to eat. The vinegar which the cook uses +belongs to a large group of compounds known as acids. The acids are +common in nature. They have the power not only of making salads sour but +also of making land sour. Frequently land becomes so sour from acids +forming in it that it will not bear its usual crops. The acids must then +be removed or the land will become useless.</p> + +<p>The land may be soured in several ways. Whenever a large amount of +vegetable matter decays in land, acids are formed, and at times sourness +of the soil results. Often soils sour because they are not well drained +or because, from lack of proper tillage, air cannot make its way into +the soil. Sometimes all these causes may combine to produce sourness.<span class='pagenum'><a name="Page_316" id="Page_316">[Pg 316]</a></span> +Since most crops cannot thrive on very sour soil, the farmer must find +some method of making his land sweet again.</p> + +<p>So far as we now know, liming the land is the cheapest and surest way of +overcoming the sourness. In addition to sweetening the soil by +overcoming the acids, lime aids the land in other ways: it quickens the +growth of helpful bacteria; it loosens stiff, heavy clay soils and +thereby fits them for easier tillage; it indirectly sets free the potash +and phosphoric acid so much needed by plants; and it increases the +capillarity of soils.</p> + +<p>However, too much must not be expected of lime. Often a farmer's yield +is so increased after he has scattered lime over his fields that he +thinks that lime alone will keep his land fertile. This belief explains +the saying, "Lime enriches the father but beggars the son." The +continued use of lime without other fertilization will indeed leave poor +land for the son. Lime is just as necessary to plant growth as the +potash and nitrogen and phosphoric acid about which we hear so much, but +it cannot take the place of these plant foods. Its duty is to aid, not +to displace them.</p> + +<p>We can tell by the taste when salads are too sour; it is more difficult +to find out whether land is sour. There are, however, some methods that +will help to determine the sourness of the soil.</p> + +<p>In the first place, if land is unusually sour, you can determine this +fact by a simple test. Buy a pennyworth of blue litmus paper from a drug +store. Mix some of the suspected soil with a little water and bury the +litmus paper in the mixture. If the paper turns red the soil is sour.</p> + +<p>In the second place, the leguminous crops are fond of lime. Clover and +vetch remove so much lime from the soil that they are often called lime +plants. If clover and vetch refuse<span class='pagenum'><a name="Page_317" id="Page_317">[Pg 317]</a></span> to grow on land on which they +formerly flourished, it is generally, though not always, a sign that the +land needs lime.</p> + +<p>In the third place, when water grasses and certain weeds spring up on +land, that land is usually acid, and lime will be helpful. Moreover, +fields adjoining land on which cranberries, raspberries, blackberries, +or gallberries are growing wild, may always be suspected of more or less +sourness.</p> + +<p>Four forms of lime are used on land. These, each called by different +names, are as follows:</p> + +<p>First, quicklime, which is also called burnt lime, caustic lime, +builders' lime, rock lime, and unslaked lime.</p> + +<p>Second, air-slaked lime, which is also known as carbonate of lime, +agricultural lime, marl, and limestone.</p> + +<p>Third, water-slaked, or hydrated, lime.</p> + +<p>Fourth, land plaster, or gypsum. This form of lime is known to the +chemists as sulphate of lime. Do not forget that this last form is never +to be used on sour lands. We shall therefore not consider it further.</p> + +<p>Air-slaked lime is simply quicklime which has taken from the air a gas +called carbon dioxide. This is the same gas that you breathe out from +your lungs.</p> + +<p>Water-slaked lime is quicklime to which water has been added. In other +words, both of these are merely weakened forms of quicklime. One hundred +pounds of quicklime is equal in richness to 132 pounds of water-slaked +lime and to 178 pounds of air-slaked lime. These figures should be +remembered by a farmer when he is buying lime. If he can buy a fair +grade of quicklime delivered at his railway station for $5.00 a ton, he +cannot afford to pay more than $3.75 a ton for water-slaked lime, nor +more than $2.75 for air-slaked lime of equal grade. Quicklime should +always be slaked before it is applied to the soil.<span class='pagenum'><a name="Page_318" id="Page_318">[Pg 318]</a></span></p> + +<p>As a rule lime should be spread broadcast and then harrowed or disked +thoroughly into the soil. This is best done after the ground has been +plowed. For pastures or meadows air-slaked lime is used as a +top-dressing. When air-slaked lime is used it may be spread broadcast in +the spring; the other forms should be applied in the fall or in the +early winter.</p> + + +<h3>SECTION LXVII. BIRDS</h3> + +<p>What do birds do in the world? is an important question for us to think +about. First, we must gain by observation and by personal acquaintance +with the living birds a knowledge of their work and their way of doing +it. In getting this knowledge, let us also consider what we can do for +our birds to render their work as complete and effective as possible.</p> + +<p>Think of what the birds are doing on every farm, in every garden, and +about every home in the land. Think of the millions of beautiful wings, +of the graceful and attractive figures, of the cunning nests, and of the +singing throats! Do you think that the whole service of the birds is to +be beautiful, to sing charmingly, and to rear their little ones? By no +means is this their chief service to man. Aside from these services the +greatest work of birds is to destroy insects. It is one of the wise +provisions of nature that many of the most brilliantly winged and most +enchanting songsters are our most practical friends.</p> + +<p>Not all birds feed on insects and animals; but even those that eat but a +small amount of insect food may still destroy insects that would have +damaged fruit and crops much more than the birds themselves do.</p> + +<p>As to their food, birds are divided into three general classes. First, +those that live wholly or almost wholly on<span class='pagenum'><a name="Page_319" id="Page_319">[Pg 319]</a></span> insects. These are called +insectivorous birds. Chief among these are the warblers, cuckoos, +swallows, martins, flycatchers, nighthawks, whippoorwills, swifts, and +humming-birds. We cannot have too many of these birds. They should be +encouraged and protected. They should be supplied with shelter and +water.</p> + +<p>Birds of the second class feed by preference on fruits, nuts, and grain. +The bluebird, robin, wood thrush, mocking-bird, catbird, chickadee, +cedar-bird, meadow lark, oriole, jay, crow, and woodpecker belong to +this group. These birds never fail to perform a service for us by +devouring many weed seeds.</p> + +<div class="figright"> + <img src="images/img342.jpg" width="157" height="200" + alt="Fig. 280." /><br /> + <b><span class="smcap">Fig. 280. A Kingbird</span></b> + </div> + +<p>The third class is known as the hard-billed birds. It includes those +birds which live principally on seeds and grain—the canary, goldfinch, +sparrow, and some others.</p> + +<p>Birds that come early, like the bluebird, robin, and redwing, are of +special service in destroying insects before the insects lay their eggs +for the season.</p> + +<p>The robins on the lawn search out the caterpillars and cutworms. The +chipping sparrow and the wren in the shrubbery look out for all kinds of +insects. They watch over the orchard and feed freely on the enemies of +the apple and other fruit trees. The trunks of these trees are often +attacked by borers, which gnaw holes in the bark and wood, and often +cause the death of the trees. The woodpeckers hunt for these<span class='pagenum'><a name="Page_320" id="Page_320">[Pg 320]</a></span> appetizing +borers and by means of their barbed tongues bring them from their +hiding-places. On the outside of the bark of the trunk and branches the +bark lice work. These are devoured by the nuthatches, creepers, and +chickadees.</p> + +<div class="figleft"> + <img src="images/img343.jpg" width="158" height="200" + alt="Fig. 281." /><br /> + <b><span class="smcap">Fig. 281. A Warbler</span></b> + </div> + +<p>During the winter the bark is the hiding-place for hibernating insects, +which, like plant lice, feed in summer on the leaves. Throughout the +winter a single chickadee will destroy great numbers of the eggs of the +cankerworm moth and of the plant louse. The blackbirds, meadow larks, +crows, quail, and sparrows are the great protectors of the meadow and +field crops. These birds feed on the army worms and cutworms that do so +much injury to the young shoots; they also destroy the chinch bug and +the grasshopper, both of which feed on cultivated plants.</p> + +<p>A count of all the different kinds of animals shows that insects make up +nine tenths of them. Hence it is easy to see that if something did not +check their increase they would soon almost overrun the earth. Our +forests and orchards furnish homes and breeding-places for most of these +insects. Suppose the injurious insects were allowed to multiply +unchecked in the forests, their numbers would so increase that they +would invade our fields and create as much terror among the farmers as +they did in Pharaoh's Egypt. The birds are the only direct<span class='pagenum'><a name="Page_321" id="Page_321">[Pg 321]</a></span> friends man +has to destroy these harmful insects. What benefactors, then, these +little feathered neighbors are!</p> + +<div class="figright"> + <img src="images/img344.jpg" width="200" height="189" + alt="Fig. 282." /><br /> + <b><span class="smcap">Fig. 282. The Hairy Woodpecker</span></b> + </div> +<p>It has been estimated that a bird will devour thirty insects daily. Even +in a widely extended forest region a very few birds to the acre, if they +kept up this rate, would daily destroy many bushels of insects that +would play havoc with the neighboring orchards and fields.</p> + +<p>Do not imagine, however, that to destroy insects is the only use of +birds. The day is far more delightful when the birds sing, and when we +see them flit in and out, giving us a glimpse now and then of their +pretty coats and quaint ways. By giving them a home we can surround +ourselves with many birds, sweet of song and brilliant of plumage.</p> + +<p>If the birds felt that man were a friend and not a foe, they would often +turn to him for protection. During times of severe storm, extreme +drought, or scarcity of food, if the birds were sufficiently tamed to +come to man as their friend, as they do in rare cases now, a little food +and shelter might tide them over the hard time and their service +afterwards would repay the outlay a thousandfold. If the boys in your +families would build bird-houses about the house and barn and in shade +trees, they might save yearly a great number of birds. In building these +places of shelter and comfort, due<span class='pagenum'><a name="Page_322" id="Page_322">[Pg 322]</a></span> care must be taken to keep them +clear of English sparrows and out of the reach of cats and bird-dogs.</p> + +<p>Whatever we do to attract the birds to make homes on the premises must +be done at the right time and in the right way. Think out carefully what +materials to provide for them. Bits of string, linen, cotton, yarn, tow +and other waste material, all help to induce a pair to build in the +garden.</p> + +<div class="figcenter"> + <img src="images/img345.jpg" width="400" height="258" + alt="Fig. 283." /><br /> + <b><span class="smcap">Fig. 283. Protecting our Friends</span></b> + </div> + +<p>It is an interesting study—the preparation of homes for the birds. +Trees may be pruned to make inviting crotches. A tangled, overgrown +corner in the garden will invite some birds to nest.</p> + +<p>Wrens, bluebirds, chickadees, martins, and some other varieties are all +glad to set up housekeeping in man-made houses. The proper size for a +bird-room is easily remembered. Give each room six square inches of +floor space and make it eight inches high. Old, weathered boards should +be used; or, if paint is employed, a dull color to resemble an<span class='pagenum'><a name="Page_323" id="Page_323">[Pg 323]</a></span> old +tree-trunk will be most inviting. A single opening near the top should +be made two inches in diameter for the larger birds; but if the house is +to be headquarters for the wren, a one-inch opening is quite large +enough, and the small door serves all the better to keep out English +sparrows.</p> + +<p>The barn attic should be turned over to the swallows. Small holes may be +cut high up in the gables and left open during the time that the +swallows remain with us. They will more than pay for shelter by the good +work they do in ridding the barn of flies, gnats, and mosquitoes.</p> + + +<h3>SECTION LXVIII. FARMING ON DRY LANDS</h3> + +<p>Almost in the center of the western half of our continent there is a +vast area in which very little rain falls. This section includes nearly +three hundred million acres of land. It stretches from Canada on the +north into Texas on the south, and from the Missouri River (including +the Dakotas and western Minnesota) on the east to the Rocky Mountains on +the west. In this great area farming has to be done with little water. +This sort of farming is therefore called "dry-farming."</p> + +<p>The soil in this section is as a rule very fertile. Therefore the +difference between farming in this dry belt and farming in most of the +other sections of our country is a difference mainly due to a lack of +moisture.</p> + +<p>As water is so scarce in this region two things are of the utmost +importance: first, to save all the rain as it falls; second, to save all +the water after it has fallen. To save the falling rain it is necessary +for the ground to be in such a condition that none of the much-needed +rain may run off. Every drop should go into the soil. Hence the farmer +should never allow his top soil to harden into a crust.<span class='pagenum'><a name="Page_324" id="Page_324">[Pg 324]</a></span> Such a crust +will keep the rain from sinking into the thirsty soil. Moreover the soil +should be deeply plowed. The deeper the soil the more water it can hold. +The land should also be kept as porous as possible, for water enters a +porous soil freely. The addition of humus in the form of vegetable +manures will keep the soil in the porous condition needed. Second, after +the water has entered the soil it is important to hold it there so that +it may supply the growing crops. If the land is allowed to remain +untilled after a rain or during a hot spell, the water in it will +evaporate too rapidly and thus the soil, like a well, will go dry too +soon. To prevent this the top soil should be stirred frequently with a +disk or smoothing harrow. This stirring will form a mulch of dry soil on +the surface, and this will hold the water. Other forms of mulch have +been suggested, but the soil mulch is the only practical one. It must be +borne in mind that this surface cultivation must be regularly kept up if +the moisture is to be retained.</p> + +<div class="figcenter"> + <img src="images/img347.jpg" width="500" height="318" + alt="Fig. 284." /><br /> + <b><span class="smcap">Fig. 284. The Disk Harrow</span></b> + </div> +<p><span class='pagenum'><a name="Page_325" id="Page_325">[Pg 325]</a></span></p> + +<p>Some experiments in wheat-growing have shown how readily water might be +saved if plowing were done at the right time. Wheat sowed on land that +was plowed as soon as the summer crops were taken off yielded a very +much larger return than wheat sowed on land that remained untilled for +some time after the summer crops were gathered. This difference in yield +on lands of the same fertility was due to the fact that the early +plowing enabled the land to take up a sufficient quantity of moisture.</p> + +<div class="figcenter"> + <img src="images/img348.jpg" width="500" height="353" + alt="Fig. 285." /><br /> + <b><span class="smcap">Fig. 285. Red Kafir Corn in Shock</span></b> + </div> + +<p>In addition to a vigilant catching and saving of water, the farmer in +these dry climates must give his land the same careful attention that +lands in other regions need. The seed-bed should be most carefully +prepared. It should be deep, porous, and excellent in tilth. During the +growing season all crops should be frequently cultivated. The harrow, +the<span class='pagenum'><a name="Page_326" id="Page_326">[Pg 326]</a></span> cultivator, and the plow should be kept busy. The soil should be +kept abundantly supplied with humus.</p> + +<p>Some crops need a little different management in dry-farming. Corn, for +example, does best when it is listed; that is, planted so that it will +come up three or four inches beneath the surface. If planted in this +way, it roots better, stands up better, and requires less work.</p> + +<p>Just as breeders study what animals are best for their climates, so +farmers in the dry belt should study what crops are best suited to their +lands. Some crops, like the sorghums and Kafir corn, are peculiarly at +home in scantily watered lands. Others do not thrive. Experience is the +only sure guide to the proper selection.</p> + +<p>To sum up, then, farmers can grow good crops in these lands only when +four things are done: first, the land must be thoroughly tilled so that +water can freely enter the soil; second, the land must be frequently +cultivated so that the water will be kept in the soil; third, the crops +must be properly rotated so as to use to best advantage the food and +water supply; fourth, humus must be freely supplied so as to keep the +soil in the best possible condition.</p> + + +<h3>SECTION LXIX. IRRIGATION</h3> + +<p>Irrigation is the name given to the plan of supplying water in large +quantities to growing crops. Since the dawn of history this practice has +been more or less followed in Asia, in Africa, and in Europe. The +Spanish settlers in the southwestern part of America were probably the +first to introduce this custom into our country. In New Mexico there is +an irrigating trench that has been in constant use for three hundred +years.<span class='pagenum'><a name="Page_327" id="Page_327">[Pg 327]</a></span></p> + +<div class="figcenter"> + <img src="images/img350.jpg" width="500" height="329" + alt="Fig. 286." /><br /> + <b><span class="smcap">Fig. 286. Pumping Water for Irrigation</span></b> + </div> + +<p>The most common source of water for irrigating purposes is a river or a +smaller stream. Artesian wells are used in some parts of the country. +Windmills are sometimes used when only a small supply of water is +needed. Engines, hydraulic rams, and water-wheels are also employed. The +water-wheel is one of the oldest and one of the most useful methods of +raising water from streams. There are thousands of these in use in the +dry regions of the West. Small buckets are fastened to a large wheel, +which is turned by the current of a stream. As the wheel turns, the +buckets are filled, raised, and then emptied into a trough called a +flume. The water flows through the flume into the irrigating ditches, +which distribute it as it is needed in the fields. In some parts of +California and other comparatively dry sections, wells are sunk in or +near the beds of underground streams, and then the water is pumped into +ditches which convey it to the fields to be irrigated.<span class='pagenum'><a name="Page_328" id="Page_328">[Pg 328]</a></span></p> + +<p>Engines are often used for pumping water from streams and transferring +it to ditches or canals. The canals distribute the water over the land +or over the growing crops.</p> + +<div class="figcenter"> + <img src="images/img351.jpg" width="400" height="262" + alt="Fig. 287." /><br /> + <b><span class="smcap">Fig. 287. The Main Ditch of an Irrigation Plant</span></b> + </div> + +<p>None of these methods, however, can be used for watering very large +areas of land. Hence, as the value of farm lands increased other methods +were sought. Shrewd men began to turn longing eyes on the wide stretches +of barren land in the West. They knew that these waste lands, seemingly +so unfertile, would become most fruitful as soon as water was turned on +them. Could water enough be found? New plans to pen up floods of water +were prepared, and immense sums were spent in carrying out these plans. +Enormous dams of cemented stone were thrown across the gorges in the +foothills of the mountains. Behind these solid dams the water from the +rains and the melting snow of the mountains was backed for miles, and +was at once ready to change barrenness into fruitfulness. The stored +water is led by means of main<span class='pagenum'><a name="Page_329" id="Page_329">[Pg 329]</a></span> canals and cross ditches wherever it is +needed, and countless acres have been brought under cultivation.</p> + +<p>Water is generally applied either by making furrows for its passage +through the fields or by flooding the land. The latter plan is the +cheaper, but it can be used only on level lands. Where the land is +somewhat irregular a checking system, as it is called, is used to +distribute the water. It is taken from check to check until the entire +field has been irrigated.</p> + +<div class="figcenter"> + <img src="images/img352.jpg" width="400" height="270" + alt="Fig. 288." /><br /> + <b><span class="smcap">Fig. 288. The Process of Irrigating Corn</span></b> + </div> + +<p>The furrow method is usually employed for fruits and for farm and garden +crops. In many places the grass and grain crops are now supplied with +water by furrows instead of by flooding.</p> + +<p>Irrigated lands should be carefully and thoroughly tilled. The water for +irrigation is costly, and should be made to go as far as possible. Good +tillage saves the water. Moreover, all cultivated crops like corn, +potatoes, and orchard and truck crops ought to be cultivated frequently +to save the moisture,<span class='pagenum'><a name="Page_330" id="Page_330">[Pg 330]</a></span> to keep the soil in fit condition, and to aid the +bacteria in the soil. It was a wise farmer who said, "One does not need +to grow crops many years in order to learn that nothing can take the +place of stirring the soil."</p> + + +<h3><span class="smcap">Methods of Irrigating Crops</span></h3> + +<p><i>Tree fruits.</i> Water is conducted through very narrow furrows from three +to five feet apart, and allowed to sink about four feet deep, and to +spread under the ground. Then the supply is cut off. The object is to +wet the soil deeply, and then by tillage to hold the moisture in the +soil.</p> + +<p><i>Small fruits.</i> The common practice is to run water on each side of the +row until the rows are soaked.</p> + +<p><i>Potatoes.</i> A thorough soaking is given the land before planting-time, +and then no more than is absolutely necessary until blossoming-time. +After the blossoms appear keep the soil moist until the crop ripens.</p> + +<p><i>Garden crops.</i> Any method may be employed, but the vital point is to +cultivate the ground as early as it can be worked after it has been +irrigated.</p> + +<p><i>Meadows and alfalfa.</i> Flooding is the most common method in use. The +first irrigation comes early in the spring before growth has advanced +much, and the successive waterings after the harvesting of each crop.</p> + + +<h3>SECTION LXX. LIFE IN THE COUNTRY</h3> + +<p>As ours is a country in which the people rule, every boy and every girl +ought to be trained to take a wide-awake interest in public affairs. +This training cannot begin too early in life. A wise old man once said, +"In a republic you ought to begin to train a child for good citizenship +on the day of its birth."<span class='pagenum'><a name="Page_331" id="Page_331">[Pg 331]</a></span></p> + +<div class="figcenter"> + <img src="images/img354a.jpg" width="400" height="241" + alt="Fig. 289." /><br /> + <b><span class="smcap">Fig. 289.

Every step +taken to make the country home more attractive, to make the school and +its grounds more enjoyable, to make the way easy to the homes of +neighbors, to school, to post-office, and to church, is a step taken +toward keeping on the farm the very boys and girls who are most apt to +succeed there.</p> + +<p>Not every man who lives in the country can have a showy or costly home, +but as long as grass and flowers and vines and trees grow, any man who +wishes can have an attractive house.

Even in this day of cheap literature, +all parents cannot fill their children's home with papers, magazines, +and books, but by means of school and Sunday-school libraries, by means +of circulating book clubs, and by a little self-denial, earnest parents +can feed hungry minds just as they feed hungry bodies.</p> + +<div class="figcenter"> + <img src="images/img008.jpg" width="375" height="550" + alt="THE QUEEN OF FLOWERS FOR THE HOME." /><br /> + <b><span class="smcap">THE QUEEN OF FLOWERS FOR THE HOME.</span></b> + </div> + +<p><br /><span class='pagenum'><a name="Page_333" id="Page_333">[Pg 333]</a></span></p> + + +<div class="figcenter"> + <img src="images/img358.jpg" width="500" height="314" + alt="Fig. 291." /><br /> + <b><span class="smcap">Fig. 291.

There are a lot of things you can do with Project +Gutenberg-tm electronic works if you follow the terms of this agreement +and help preserve free future access to Project Gutenberg-tm electronic +works.

Of course, we hope that you will support the Project +Gutenberg-tm mission of promoting free access to electronic works by +freely sharing Project Gutenberg-tm works in compliance with the terms of +this agreement for keeping the Project Gutenberg-tm name associated with +the work. You can easily comply with the terms of this agreement by +keeping this work in the same format with its attached full Project +Gutenberg-tm License when you share it without charge with others. + +1.D.

You may copy it, give it away or +re-use it under the terms of the Project Gutenberg License included +with this eBook or online at www.gutenberg.org + +1.E.2. If an individual Project Gutenberg-tm electronic work is derived +from the public domain (does not contain a notice indicating that it is +posted with permission of the copyright holder), the work can be copied +and distributed to anyone in the United States without paying any fees +or charges. If you are redistributing or providing access to a work +with the phrase "Project Gutenberg" associated with or appearing on the +work, you must comply either with the requirements of paragraphs 1.E.1 +through 1.E.7 or obtain permission for the use of the work and the +Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or +1.E.9. + +1.E.3. If an individual Project Gutenberg-tm electronic work is posted +with the permission of the copyright holder, your use and distribution +must comply with both paragraphs 1.E.1 through 1.E.7 and any additional +terms imposed by the copyright holder.

Contact the +Foundation as set forth in Section 3 below. + +1.F. + +1.F.1. Project Gutenberg volunteers and employees expend considerable +effort to identify, do copyright research on, transcribe and proofread +public domain works in creating the Project Gutenberg-tm +collection. Despite these efforts, Project Gutenberg-tm electronic +works, and the medium on which they may be stored, may contain +"Defects," such as, but not limited to, incomplete, inaccurate or +corrupt data, transcription errors, a copyright or other intellectual +property infringement, a defective or damaged disk or other medium, a +computer virus, or computer codes that damage or cannot be read by +your equipment. + +1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right +of Replacement or Refund" described in paragraph 1.F.3, the Project +Gutenberg Literary Archive Foundation, the owner of the Project +Gutenberg-tm trademark, and any other party distributing a Project +Gutenberg-tm electronic work under this agreement, disclaim all +liability to you for damages, costs and expenses, including legal +fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT +LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE +PROVIDED IN PARAGRAPH F3. YOU AGREE THAT THE FOUNDATION, THE +TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE +LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR +INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH +DAMAGE. + +1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a +defect in this electronic work within 90 days of receiving it, you can +receive a refund of the money (if any) you paid for it by sending a +written explanation to the person you received the work from. If you +received the work on a physical medium, you must return the medium with +your written explanation. The person or entity that provided you with +the defective work may elect to provide a replacement copy in lieu of a +refund. If you received the work electronically, the person or entity +providing it to you may choose to give you a second opportunity to +receive the work electronically in lieu of a refund. If the second copy +is also defective, you may demand a refund in writing without further +opportunities to fix the problem. + +1.F.4. Except for the limited right of replacement or refund set forth +in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER +WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO +WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE. + +1.F.5. Some states do not allow disclaimers of certain implied +warranties or the exclusion or limitation of certain types of damages. +If any disclaimer or limitation set forth in this agreement violates the +law of the state applicable to this agreement, the agreement shall be +interpreted to make the maximum disclaimer or limitation permitted by +the applicable state law. The invalidity or unenforceability of any +provision of this agreement shall not void the remaining provisions. + +1.F.6.

Information about the Mission of Project Gutenberg-tm + +Project Gutenberg-tm is synonymous with the free distribution of +electronic works in formats readable by the widest variety of computers +including obsolete, old, middle-aged and new computers. It exists +because of the efforts of hundreds of volunteers and donations from +people in all walks of life. + +Volunteers and financial support to provide volunteers with the +assistance they need, is critical to reaching Project Gutenberg-tm's +goals and ensuring that the Project Gutenberg-tm collection will +remain freely available for generations to come. In 2001, the Project +Gutenberg Literary Archive Foundation was created to provide a secure +and permanent future for Project Gutenberg-tm and future generations. +To learn more about the Project Gutenberg Literary Archive Foundation +and how your efforts and donations can help, see Sections 3 and 4 +and the Foundation web page at http://www.pglaf.org. + + +Section 3. Information about the Project Gutenberg Literary Archive +Foundation + +The Project Gutenberg Literary Archive Foundation is a non profit +501(c)(3) educational corporation organized under the laws of the +state of Mississippi and granted tax exempt status by the Internal +Revenue Service. The Foundation's EIN or federal tax identification +number is 64-6221541. Its 501(c)(3) letter is posted at +http://pglaf.org/fundraising. Contributions to the Project Gutenberg +Literary Archive Foundation are tax deductible to the full extent +permitted by U.S. federal laws and your state's laws. + +The Foundation's principal office is located at 4557 Melan Dr. S. +Fairbanks, AK, 99712., but its volunteers and employees are scattered +throughout numerous locations. Its business office is located at +809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email +business@pglaf.org.

Newby + Chief Executive and Director + gbnewby@pglaf.org + + +Section 4. Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg-tm depends upon and cannot survive without wide +spread public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To +SEND DONATIONS or determine the status of compliance for any +particular state visit http://pglaf.org + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg Web pages for current donation +methods and addresses. Donations are accepted in a number of other +ways including checks, online payments and credit card donations. +To donate, please visit: http://pglaf.org/donate + + +Section 5. General Information About Project Gutenberg-tm electronic +works. + +Professor Michael S. Hart is the originator of the Project Gutenberg-tm +concept of a library of electronic works that could be freely shared +with anyone. For thirty years, he produced and distributed Project +Gutenberg-tm eBooks with only a loose network of volunteer support. + + +Project Gutenberg-tm eBooks are often created from several printed +editions, all of which are confirmed as Public Domain in the U.S. +unless a copyright notice is included. Thus, we do not necessarily +keep eBooks in compliance with any particular paper edition. + + +Most people start at our Web site which has the main PG search facility: + + http://www.gutenberg.org + +This Web site includes information about Project Gutenberg-tm, +including how to make donations to the Project Gutenberg Literary +Archive Foundation, how to help produce our new eBooks, and how to +subscribe to our email newsletter to hear about new eBooks. + + +</pre> + +</body> +</html> diff --git a/20772-h/images/img001.jpg b/20772-h/images/img001.jpg Binary files differnew file mode 100644

U.S.A. + + +[Illustration: GETTING READY FOR WINTER] + + + + +PREFACE + + +Since its first publication "Agriculture for Beginners" has found a +welcome in thousands of schools and homes. Naturally many suggestions as +to changes, additions, and other improvements have reached its authors. +Naturally, too, the authors have busied themselves in devising methods +to add to the effectiveness of the book. Some additions have been made +almost every year since the book was published. To embody all these +changes and helpful suggestions into a strictly unified volume; to add +some further topics and sections; to bring all farm practices up to the +ideals of to-day; to include the most recent teaching of scientific +investigators--these were the objects sought in the thorough revision +which has just been given the book. The authors hope and think that the +remaking of the book has added to its usefulness and attractiveness. + +They believe now, as they believed before, that there is no line of +separation between the science of agriculture and the practical art of +agriculture. They are assured by the success of this book that +agriculture is eminently a teachable subject. They see no difference +between teaching the child the fundamental principles of farming and +teaching the same child the fundamental truths of arithmetic, geography, +or grammar. They hold that a youth should be trained for the farm just +as carefully as he is trained for any other occupation, and that it is +unreasonable to expect him to succeed without training. + +If they are right in these views, the training must begin in the public +schools. This is true for two reasons: + +1. It is universally admitted that aptitudes are developed, tastes +acquired, and life habits formed during the years that a child is in the +public school. Hence, during these important years every child intended +for the farm should be taught to know and love nature, should be led to +form habits of observation, and should be required to begin a study of +those great laws upon which agriculture is based. A training like this +goes far toward making his life-work profitable and delightful. + +2. Most boys and girls reared on a farm get no educational training +except that given in the public schools. If, then, the truths that +unlock the doors of nature are not taught in the public schools, nature +and nature's laws will always be hid in night to a majority of our +bread-winners. They must still in ignorance and hopeless drudgery tear +their bread from a reluctant soil. + +The authors return hearty thanks to Professor Thomas F. Hunt, University +of California; Professor Augustine D. Selby, Ohio Experiment Station; +Professor W. F. Massey, horticulturist and agricultural writer; and +Professor Franklin Sherman, Jr., State Entomologist of North Carolina, +for aid in proofreading and in the preparation of some of the material. + + CONTENTS + + CHAPTER I.

By the same reasoning they might hesitate to teach +arithmetic because they do not know calculus or to teach a primary +history of the United States because they are not versed in all history. +The art of farming is based on the sciences dealing with the growth of +plants and animals. This book presents in a simple way these fundamental +scientific truths and suggests some practices drawn from them. Hence, +even though many teachers may not have plowed or sowed or harvested, +such teachers need not be embarrassed in mastering and heartily +instructing a class in nature's primary laws. + +If teachers realize how much the efficiency, comfort, and happiness of +their pupils will be increased throughout their lives from being taught +to cooeperate with nature and to take advantage of her wonderful laws, +they will eagerly begin this study. They will find also that their +pupils will be actively interested in these studies bearing on their +daily lives, and this interest will be carried over to other subjects. +Whenever you can, take the pupils into the field, the garden, the +orchard, and the dairy. Teach them to make experiments and to learn by +the use of their own eyes and brains. They will, if properly led, +astonish you by their efforts and growth. + +You will find in the practical exercises many suggestions as to +experiments that you can make with your class or with individual +members. Do not neglect this first-hand teaching. It will be a delight +to your pupils. In many cases it will be best to finish the experiments +or observational work first, and later turn to the text to amplify the +pupil's knowledge. + +Although the book is arranged in logical order, the teacher ought to +feel free to teach any topic in the season best suited to its study. +Omit any chapter or section that does not bear on your crops or does not +deal with conditions in your state. + +The United States government and the different state experiment stations +publish hundreds of bulletins on agricultural subjects. These are sent +without cost, on application. It will be very helpful to get such of +these bulletins as bear on the different sections of the book. These +will be valuable additions to your school library. The authors would +like to give a list of these bulletins bearing on each chapter, but it +would soon be out of date, for the bulletins get out of print and are +supplanted by newer ones. However, the United States Department of +Agriculture prints a monthly list of its publications, and each state +experiment station keeps a list of its bulletins. A note to the +Secretary of Agriculture, Washington, D.C., or to your own state +experiment station will promptly bring you these lists, and from them +you can select what you need for your school. + + + + +AGRICULTURE FOR BEGINNERS + +CHAPTER I + +THE SOIL + + +SECTION I. ORIGIN OF THE SOIL + +The word _soil_ occurs many times in this little book. In agriculture +this word is used to describe the thin layer of surface earth that, like +some great blanket, is tucked around the wrinkled and age-beaten form of +our globe. The harder and colder earth under this surface layer is +called the _subsoil_. It should be noted, however, that in waterless and +sun-dried regions there seems little difference between the soil and the +subsoil. + +Plants, insects, birds, beasts, men,--all alike are fed on what grows in +this thin layer of soil. If some wild flood in sudden wrath could sweep +into the ocean this earth-wrapping soil, food would soon become as +scarce as it was in Samaria when mothers ate their sons. The face of the +earth as we now see it, daintily robed in grass, or uplifting waving +acres of corn, or even naked, water-scarred, and disfigured by man's +neglect, is very different from what it was in its earliest days. How +was it then? How was the soil formed? + +Learned men think that at first the surface of the earth was solid rock. +How was this rock changed into workable soil? Occasionally a curious boy +picks up a rotten stone, squeezes it, and finds his hands filled with +dirt, or soil. Now, just as the boy crumbled with his fingers this +single stone, the great forces of nature with boundless patience +crumbled, or, as it is called, disintegrated, the early rock mass. The +simple but giant-strong agents that beat the rocks into powder with a +clublike force a millionfold more powerful than the club force of +Hercules were chiefly (1) heat and cold; (2) water, frost, and ice; (3) +a very low form of vegetable life; and (4) tiny animals--if such minute +bodies can be called animals. In some cases these forces acted singly; +in others, all acted together to rend and crumble the unbroken stretch +of rock. Let us glance at some of the methods used by these skilled +soil-makers. + +Heat and cold are working partners. You already know that most hot +bodies shrink, or contract, on cooling. The early rocks were hot. As the +outside shell of rock cooled from exposure to air and moisture it +contracted. This shrinkage of the rigid rim of course broke many of the +rocks, and here and there left cracks, or fissures. In these fissures +water collected and froze. As freezing water expands with irresistible +power, the expansion still further broke the rocks to pieces. The +smaller pieces again, in the same way, were acted on by frost and ice +and again crumbled. This process is still a means of soil-formation. + +Running water was another giant soil-former. If you would understand its +action, observe some usually sparkling stream just after a washing rain. +The clear waters are discolored by mud washed in from the surrounding +hills. As though disliking their muddy burden, the waters strive to +throw it off. Here, as low banks offer chance, they run out into +shallows and drop some of it. Here, as they pass a quiet pool, they +deposit more. At last they reach the still water at the mouth of the +stream, and there they leave behind the last of their mud load, and +often form of it little three-sided islands called _deltas_. In the same +way mighty rivers like the Amazon, the Mississippi, and the Hudson, when +they are swollen by rain, bear great quantities of soil in their sweep +to the seas. Some of the soil they scatter over the lowlands as they +whirl seaward; the rest they deposit in deltas at their mouths. It is +estimated that the Mississippi carries to the ocean each year enough +soil to cover a square mile of surface to a depth of two hundred and +sixty-eight feet. + +[Illustration: FIG. 1. ROCK MARKED BY THE SCRAPING OF A GLACIER OVER IT] + +The early brooks and rivers, instead of bearing mud, ran oceanward +either bearing ground stone that they themselves had worn from the rocks +by ceaseless fretting, or bearing stones that other forces had already +dislodged. The large pieces were whirled from side to side and beaten +against one another or against bedrock until they were ground into +smaller and smaller pieces. The rivers distributed this rock soil just +as the later rivers distribute muddy soil. For ages the moving waters +ground against the rocks. Vast were the waters; vast the number of +years; vast the results. + +Glaciers were another soil-producing agent. Glaciers are streams "frozen +and moving slowly but irresistibly onwards, down well-defined valleys, +grinding and pulverizing the rock masses detached by the force and +weight of their attack." Where and how were these glaciers formed? + +Once a great part of upper North America was a vast sheet of ice. +Whatever moisture fell from the sky fell as snow. No one knows what made +this long winter of snow, but we do know that snows piled on snows until +mountains of white were built up. The lower snow was by the pressure of +that above it packed into ice masses. By and by some change of climate +caused the masses of ice to break up somewhat and to move south and +west. These moving masses, carrying rock and frozen earth, ground them +to powder. King thus describes the stately movement of these snow +mountains: "Beneath the bottom of this slowly moving sheet of ice, which +with more or less difficulty kept itself conformable with the face of +the land over which it was riding, the sharper outstanding points were +cut away and the deeper river canons filled in. Desolate and rugged +rocky wastes were thrown down and spread over with rich soil." + +The joint action of air, moisture, and frost was still another agent of +soil-making. This action is called _weathering_. Whenever you have +noticed the outside stones of a spring-house, you have noticed that tiny +bits are crumbling from the face of the stones, and adding little by +little to the soil. This is a slow way of making additions to the soil. +It is estimated that it would take 728,000 years to wear away limestone +rock to a depth of thirty-nine inches. But when you recall the +countless years through which the weather has striven against the rocks, +you can readily understand that its never-wearying activity has added +immensely to the soil. + +In the rock soil formed in these various ways, and indeed on the rocks +themselves, tiny plants that live on food taken from the air began to +grow. They grew just as you now see mosses and lichens grow on the +surface of rocks. The decay of these plants added some fertility to the +newly formed soil. The life and death of each succeeding generation of +these lowly plants added to the soil matter accumulating on the rocks. +Slowly but unceasingly the soil increased in depth until higher +vegetable forms could flourish and add their dead bodies to it. This +vegetable addition to the soil is generally known as _humus_. + +[Illustration: FIG. 2. GROUND ROCK AT END OF A GLACIER] + +In due course of time low forms of animal life came to live on these +plants, and in turn by their work and their death to aid in making a +soil fit for the plowman. + +Thus with a deliberation that fills man with awe, the powerful forces of +nature splintered the rocks, crumbled them, filled them with plant food, +and turned their flinty grains into a soft, snug home for vegetable +life. + + +SECTION II. TILLAGE OF THE SOIL + +A good many years ago a man by the name of Jethro Tull lived in England. +He was a farmer and a most successful man in every way. He first taught +the English people and the world the value of thorough tillage of the +soil. Before and during his time farmers did not till the soil very +intelligently. They simply prepared the seed-bed in a careless manner, +as a great many farmers do to-day, and when the crops were gathered the +yields were not large. + +Jethro Tull centered attention on the important fact that careful and +thorough tillage increases the available plant food in the soil. He did +not know why his crops were better when the ground was frequently and +thoroughly tilled, but he knew that such tillage did increase his yield. +He explained the fact by saying, "Tillage is manure." We have since +learned the reason for the truth that Tull taught, and, while his +explanation was incorrect, the practice that he was following was +excellent. The stirring of the soil enables the air to circulate through +it freely, and permits a breaking down of the compounds that contain the +elements necessary to plant growth. + +You have seen how the air helps to crumble the stone and brick in old +buildings. It does the same with soil if permitted to circulate freely +through it. The agent of the air that chiefly performs this work is +called carbonic acid gas, and this gas is one of the greatest helpers +the farmer has in carrying on his work. We must not forget that in soil +preparation the air is just as important as any of the tools and +implements used in cultivation. + +[Illustration: FIG. 3. SLOPE TO WATER SHOWS SOIL WEATHERED FROM FACE +OF CLIFF] + +If the soil is fertile and if deep plowing has always been done, good +crops will result, other conditions being favorable. If, however, the +tillage is poor, scanty harvests will always result. For most soils a +two-horse plow is necessary to break up and pulverize the land. + +A shallow soil can always be improved by properly deepening it. The +principle of greatest importance in soil-preparation is the gradual +deepening of the soil in order that plant-roots may have more +comfortable homes. If the farmer has been accustomed to plow but four +inches deep, he should adjust the plow so as to turn five inches at the +next plowing, then six, and so on until the seed-bed is nine or ten +inches deep. This gradual deepening will not injure the soil but will +put it quickly in good condition. If to good tillage rotation of crops +be added, the soil will become more fertile with each succeeding year. + +[Illustration: FIG. 4. MIXED GRASSES GROWN FOR FORAGE] + +The plow, harrow, and roller are all necessary to good tillage and to a +proper preparation of the seed-bed. The soil must be made compact and +clods of all sizes must be crushed. Then the air circulates freely, and +paying crops are the rule and not the exception. + +Tillage does these things: it increases the plant-food supply, destroys +weeds, and influences the moisture content of the soil. + + + =EXERCISE= + + 1. What tools are used in tillage? + + 2. How should a poor and shallow soil be treated? + + 3. Why should a poor and shallow soil be well compacted before + sowing the crop? + + 4. Explain the value of a circulation of air in the soil. + + 5. What causes iron to rust? + + 6. Why is a two-horse turning-plow better than a one-horse plow? + + 7. Where will clods do the least harm--on top of the soil or below + the surface? + + 8. Do plant roots penetrate clods? + + 9. Are earthworms a benefit or an injury to the soil? + + 10. Name three things that tillage does. + + +SECTION III. THE MOISTURE OF THE SOIL + +Did any one ever explain to you how important water is to the soil, or +tell you why it is so important? Often, as you know, crops entirely fail +because there is not enough water in the soil for the plants to drink. +How necessary is it, then, that the soil be kept in the best possible +condition to catch and hold enough water to carry the plant through dry, +hot spells! Perhaps you are ready to ask, "How does the mouthless plant +drink its stored-up water?" + +The plant gets all its water through its roots. You have seen the tiny +threadlike roots of a plant spreading all about in fine soil; they are +down in the ground taking up plant food and water for the stalk and +leaves above. The water, carrying plant food with it, rises in a simple +but peculiar way through the roots and stems. + +The plants use the food for building new tissue, that is, for growth. +The water passes out through the leaves into the air. When the summers +are dry and hot and there is but little water in the soil, the leaves +shrink up. This is simply a method they have of keeping the water from +passing too rapidly off into the air. I am sure you have seen the corn +blades all shriveled on very hot days. This shrinkage is nature's way of +diminishing the current of water that is steadily passing through the +plant. + +A thrifty farmer will try to keep his soil in such good condition that +it will have a supply of water in it for growing crops when dry and hot +weather comes. He can do this by deep plowing, by subsoiling, by adding +any kind of decaying vegetable matter to the soil, and by growing crops +that can be tilled frequently. + +The soil is a great storehouse for moisture. After the clouds have +emptied their waters into this storehouse, the water of the soil comes +to the surface, where it is evaporated into the air. The water comes to +the surface in just the same way that oil rises in a lamp-wick. This +rising of the water is called _capillarity_. + +[Illustration: FIG. 5. AN ENLARGED VIEW OF A SECTION OF MOIST SOIL, +SHOWING AIR SPACES AND SOIL PARTICLES] + +It is necessary to understand what is meant by this big word. If into a +pan of water you dip a glass tube, the water inside the tube rises above +the level of the water in the pan. The smaller the tube the higher will +the water rise. The greater rise inside is perhaps due to the fact that +the glass attracts the particles of water more than the particles of +water attract one another. Now apply this principle to the soil. + +[Illustration: FIG. 6. THE RIGHT WAY TO PLOW] + +The soil particles have small spaces between them, and the spaces act +just as the tube does. When the water at the surface is carried away by +drying winds and warmth, the water deeper in the soil rises through +the soil spaces. In this way water is brought from its soil storehouse +as plants need it. + +[Illustration: FIG. 7. APPARATUS FOR TESTING THE HOLDING OF WATER BY +DIFFERENT SOILS] + +Of course when the underground water reaches the surface it evaporates. +If we want to keep it for our crops, we must prepare a trap to hold it. +Nature has shown us how this can be done. Pick up a plank as it lies on +the ground. Under the plank the soil is wet, while the soil not covered +by the plank is dry. Why? Capillarity brought the water to the surface, +and the plank, by keeping away wind and warmth, acted as a trap to hold +the moisture. Now of course a farmer cannot set a trap of planks over +his fields, but he can make a trap of dry earth, and that will do just +as well. + +When a crop like corn or cotton or potatoes is cultivated, the fine, +loose dirt stirred by the cultivating-plow will make a mulch that serves +to keep water in the soil in the same way that the plank kept moisture +under it. The mulch also helps to absorb the rains and prevents the +water from running off the surface. Frequent cultivation, then, is one +of the best possible ways of saving moisture. Hence the farmer who most +frequently stirs his soil in the growing season, and especially in +seasons of drought, reaps, other things being equal, a more abundant +harvest than if tillage were neglected. + + + =EXERCISE= + + 1. Why is the soil wet under a board or under straw? + + 2. Will a soil that is fine and compact produce better crops than + one that is loose and cloddy? Why? + + 3. Since the water which a plant uses comes through the roots, can + the morning dew afford any assistance? + + 4. Why are weeds objectionable in a growing crop? + + 5. Why does the farmer cultivate growing corn and cotton? + + +SECTION IV. HOW THE WATER RISES IN THE SOIL + +[Illustration: FIG. 8. USING LAMP-CHIMNEYS TO SHOW THE RISE OF WATER +IN SOIL] + +When the hot, dry days of summer come, the soil depends upon the +subsoil, or undersoil, for the moisture that it must furnish its growing +plants. The water was stored in the soil during the fall, winter, and +spring months when there was plenty of rain. If you dig down into the +soil when everything is dry and hot, you will soon reach a cool, moist +undersoil. The moisture increases as you dig deeper into the soil. + +Now the roots of plants go down into the soil for this moisture, because +they need the water to carry the plant food up into the stems and +leaves. + +You can see how the water rises in the soil by performing a simple +experiment. + + + =EXPERIMENT= + + Take a lamp-chimney and fill it with fine, dry dirt. The dirt from + a road or a field will do. Tie over the smaller end of the + lamp-chimney a piece of cloth or a pocket handkerchief, and place + this end in a shallow pan of water. If the soil in the lamp-chimney + is clay and well packed, the water will quickly rise to the top. + + By filling three or four lamp-chimneys with as many different + soils, the pupil will see that the water rises more slowly in some + than in others. + + Now take the water pan away, and the water in the lamp-chimneys + will gradually evaporate. Study for a few days the effect of + evaporation on the several soils. + + +SECTION V. DRAINING THE SOIL + +A wise man was once asked, "What is the most valuable improvement ever +made in agriculture?" He answered, "Drainage." Often soils unfit for +crop-production because they contain too much water are by drainage +rendered the most valuable of farming lands. + +Drainage benefits land in the following ways: + +1. It deepens the subsoil by removing unnecessary water from the spaces +between the soil particles. This admits air. Then the oxygen which is in +the air, by aiding decay, prepares plant food for vegetation. + +2. It makes the surface soil, or topsoil, deeper. It stands to reason +that the deeper the soil the more plant food becomes available for plant +use. + +3. It improves the texture of the soil. Wet soil is sticky. Drainage +makes this sticky soil crumble and fall apart. + +4. It prevents washing. + +5. It increases the porosity of soils and permits roots to go deeper +into the soil for food and moisture. + +6. It increases the warmth of the soil. + +7. It permits earlier working in spring and after rains. + +[Illustration: FIG. 9. LAYING A TILE DRAIN] + +8. It favors the growth of germs which change the unavailable nitrogen +of the soil into nitrates; that is, into the form of nitrogen most +useful to plants. + +9. It enables plants to resist drought better because the roots go into +the ground deeper early in the season. + +A soil that is hard and wet will not grow good crops. The +nitrogen-gathering crops will store the greatest quantity of nitrogen in +the soil when the soil is open to the free circulation of the air. +These valuable crops cannot do this when the soil is wet and cold. + +Sandy soils with sandy subsoils do not often need drainage; such soils +are naturally drained. With clay soils it is different. It is very +important to remove the stagnant water in them and to let the air in. + +When land has been properly drained the other steps in improvement are +easily taken. After soil has been dried and mellowed by proper drainage, +then commercial fertilizers, barnyard manure, cowpeas, and clover can +most readily do their great work of improving the texture of the soil +and of making it fitter for plant growth. + +[Illustration: FIG. 10. A TILE IN POSITION] + +=Tile Drains.= Tile drains are the best and cheapest that can be used. +It would not be too strong to say that draining by tiles is the most +perfect drainage. Thousands of practical tests in this country have +proved the superiority of tile draining for the following reasons: + +1. Good tile drains properly laid last for years and do not fill up. + +2. They furnish the cheapest possible means of removing too much water +from the soil. + +3. They are out of reach of all cultivating tools. + +4. Surface water in filtering through the tiles leaves its nutritious +elements for plant growth. + + + =EXPERIMENTS= + + =To show the Effect of Drainage.= Take two tomato cans and fill + both with the same kind of soil. Punch several holes in the bottom + of one to drain the soil above and to admit air circulation. Leave + the other unpunctured. Plant seeds of any kind in both cans and + keep in a warm place. Add every third day equal quantities of + water. Let seeds grow in both cans and observe the difference in + growth for two or three weeks. + + =To show the Effect of Air in Soils.= Take two tomato cans; fill + one with soil that is loose and warm, and the other with wet clay + or muck from a swampy field. Plant a few seeds of the same kind in + each and observe how much better the dry, warm, open soil is for + growing farm crops. + + +SECTION VI. IMPROVING THE SOIL + +We hear a great deal about the exhaustion or wearing out of the soil. +Many uncomfortable people are always declaring that our lands will no +longer produce profitable crops, and hence that farming will no longer +pay. + +Now it is true, unfortunately, that much land has been robbed of its +fertility, and, because this is true, we should be most deeply +interested in everything that leads to the improvement of our soils. + +When our country was first discovered and trees were growing everywhere, +we had virgin soils, or new soils that were rich and productive because +they were filled with vegetable matter and plant food. There are not +many virgin soils now because the trees have been cut from the best +lands, and these lands have been farmed so carelessly that the vegetable +matter and available plant food have been largely used up. Now that +fresh land is scarce it is very necessary to restore fertility to these +exhausted lands. What are some of the ways in which this can be done? + +[Illustration: FIG. 11. CLOVER IS A SOIL-IMPROVER] + +There are several things to be done in trying to reclaim worn-out land. +One of the first of these is to till the land well. Many of you may have +heard the story of the dying father who called his sons about him and +whispered feebly, "There is great treasure hidden in the garden." The +sons could hardly wait to bury their dead father before, thud, thud, +thud, their picks were going in the garden. Day after day they dug; they +dug deep; they dug wide. Not a foot of the crop-worn garden escaped the +probing of the pick as the sons feverishly searched for the expected +treasure. But no treasure was found. Their work seemed entirely useless. + +[Illustration: FIG. 12. INCREASING THE PRODUCTIVE POWER OF THE SOIL +Second crop of cowpeas on old, abandoned land] + +"Let us not lose every whit of our labor; let us plant this pick-scarred +garden," said the eldest. So the garden was planted. In the fall the +hitherto neglected garden yielded a harvest so bountiful, so unexpected, +that the meaning of their father's words dawned upon them. "Truly," they +said, "a treasure was hidden there. Let us seek it in all our fields." + +The story applies as well to-day as it did when it was first told. +Thorough culture of the soil, frequent and intelligent tillage--these +are the foundations of soil-restoration. + +Along with good tillage must go crop-rotation and good drainage. A +supply of organic matter will prevent heavy rains from washing the soil +and carrying away plant food. Drainage will aid good tillage in allowing +air to circulate between the soil particles and in arranging plant food +so that plants can use it. + +But we must add humus, or vegetable matter, to the soil. You remember +that the virgin soils contained a great deal of vegetable matter and +plant food, but by the continuous growing of crops like wheat, corn, and +cotton, and by constant shallow tillage, both humus and plant food have +been used up. Consequently much of our cultivated soil to-day is hard +and dead. + +There are three ways of adding humus and plant food to this lifeless +land: the first way is to apply barnyard manure (to adopt this method +means that livestock raising must be a part of all farming); the second +way is to adopt rotation of crops, and frequently to plow under crops +like clover and cowpeas; the third way is to apply commercial +fertilizers. + +To summarize: if we want to make our soil better year by year, we must +cultivate well, drain well, and in the most economical way add humus and +plant food. + + + =EXPERIMENT= + + Select a small area of ground at your home and divide it into four + sections, as shown in the following sketch: + + On Section _A_ apply barnyard manure; on Section _B_ apply + commercial fertilizers; on Section _C_ apply nothing, but till + well; on Section _D_ apply nothing, and till very poorly. + + _A_, _B_, and _C_ should all be thoroughly plowed and harrowed. + Then add barnyard manure to _A_, commercial fertilizers to _B_, and + harrow _A_, _B_, and _C_ at least four times until the soil is + mellow and fine. _D_ will most likely be cloddy, like many fields + that we often see. Now plant on each plat some crop like cotton, + corn, or wheat. When the plats are ready to harvest, measure the + yield of each and determine whether the increased yield of the best + plats has paid for the outlay for tillage and manure. The pupil + will be much interested in the results obtained from the first + crop. + + [Illustration: FIG. 13] + + Now follow a system of crop-rotation on the plats. Clover can + follow corn or cotton or wheat; and cowpeas, wheat. Then determine + the yield of each plat for the second crop. By following these + plats for several years, and increasing the number, the pupils will + learn many things of greatest value. + + + + +SECTION VII. MANURING THE SOIL + +In the early days of our history, when the soil was new and rich, we +were not compelled to use large amounts of manures and fertilizers. Yet +our histories speak of an Indian named Squanto who came into one of the +New England colonies and showed the first settlers how, by putting a +fish in each hill of corn, they could obtain larger yields. + +If people in those days, with new and fertile soils, could use manures +profitably, how much more ought we to use them in our time, when soils +have lost their virgin fertility, and when the plant food in the soil +has been exhausted by years and years of cropping! + +To sell year after year all the produce grown on land is a sure way to +ruin it. If, for example, the richest land is planted every year in +corn, and no stable or farmyard manure or other fertilizer returned to +the soil, the land so treated will of course soon become too poor to +grow any crop. If, on the other hand, clover or alfalfa or corn or +cotton-seed meal is fed to stock, and the manure from the stock returned +to the soil, the land will be kept rich. Hence those farmers who do not +sell such raw products as cotton, corn, wheat, oats, and clover, but who +market articles made from these raw products, find it easier to keep +their land fertile. For illustration: if instead of selling hay, farmers +feed it to sheep and sell meat and wool; if instead of selling cotton +seed, they feed its meal to cows, and sell milk and butter; if instead +of selling stover, they feed it to beef cattle, they get a good price +for products and in addition have all the manure needed to keep their +land productive and increase its value each year. + +[Illustration:FIG. 14. RELATION OF HUMUS TO GROWTH OF CORN +1, clay subsoil; 2, same, with fertilizer; 3, same, with humus] + +If we wish to keep up the fertility of our lands we should not allow +anything to be lost from our farms. All the manures, straw, roots, +stubble, healthy vines--in fact everything decomposable--should be +plowed under or used as a top-dressing. Especial care should be taken in +storing manure. It should be watchfully protected from sun and rain. If +a farmer has no shed under which to keep his manure, he should scatter +it on his fields as fast as it is made. + +[Illustration: FIG. 15. THE COTTON PLANT WITH AND WITHOUT FOOD +In left top pot, no plant food; in left bottom pot, plant food scanty; +in both right pots, all elements of plant food present] + +He should understand also that liquid manure is of more value than +solid, because that important plant food, nitrogen, is found almost +wholly in the liquid portion. Some of the phosphoric acid and +considerable amounts of the potash are also found in the liquid manure. +Hence economy requires that none of this escape either by leakage or by +fermentation. Sometimes one can detect the smell of ammonia in the +stable. This ammonia is formed by the decomposition of the liquid +manure, and its loss should be checked by sprinkling some floats, acid +phosphate, or muck over the stable floor. + +Many farmers find it desirable to buy fertilizers to use with the manure +made on the farm. In this case it is helpful to understand the +composition, source, and availability of the various substances +composing commercial fertilizers. The three most valuable things in +commercial fertilizers are nitrogen, potash, and phosphoric acid. + +The nitrogen is obtained from (1) nitrate of soda mined in Chile, (2) +ammonium sulphate, a by-product of the gas works, (3) dried blood and +other by-products of the slaughter-houses, and (4) cotton-seed meal. +Nitrate of soda is soluble in water and may therefore be washed away +before being used by plants. For this reason it should be applied in +small quantities and at intervals of a few weeks. + +Potash is obtained in Germany, where it is found in several forms. It is +put on the market as muriate of potash, sulphate of potash, kainite, +which contains salt as an impurity, and in other impure forms. Potash is +found also in _unleached_ wood ashes. + +Phosphoric acid is found in various rocks of Tennessee, Florida, and +South Carolina, and also to a large extent in bones. The rocks or bones +are usually treated with sulphuric acid. This treatment changes the +phosphoric acid into a form ready for plant use. + +These three kinds of plant food are ordinarily all that we need to +supply. In some cases, however, lime has to be added. Besides being a +plant food itself, lime helps most soils by improving the structure of +the grains; by sweetening the soil, thereby aiding the little living +germs called _bacteria_; by hastening the decay of organic matter; and +by setting free the potash that is locked up in the soil. + + + + +CHAPTER II + +THE SOIL AND THE PLANT + + +SECTION VIII. ROOTS + + +[Illustration: FIG. 16. ROOT-HAIRS ON A RADISH] + +You have perhaps observed the regularity of arrangement in the twigs and +branches of trees. Now pull up the roots of a plant, as, for example, +sheep sorrel, Jimson weed, or some other plant. Note the branching of +the roots. In these there is no such regularity as is seen in the twig. +Trace the rootlets to their finest tips. How small, slender, and +delicate they are! Still we do not see the finest of them, for in taking +the plant from the ground we tore the most delicate away. In order to +see the real construction of a root we must grow one so that we may +examine it uninjured. To do this, sprout some oats in a germinator or in +any box in which one glass side has been arranged and allow the oats to +grow till they are two or more inches high. Now examine the roots and +you will see very fine hairs, similar to those shown in the accompanying +figure, forming a fuzz over the surface of the roots near the tips. This +fuzz is made of small hairs standing so close together that there are +often as many as 38,200 on a single square inch. Fig. 17 shows how a +root looks when it has been cut crosswise into what is known as a cross +section. The figure is much increased in size. You can see how the +root-hairs extend from the root in every direction. Fig. 18 shows a +single root-hair very greatly enlarged, with particles of sand sticking +to it. + +[Illustration: FIG. 17. A SLICE OF A ROOT +Highly magnified] + +These hairs are the feeding-organs of the roots, and they are formed +only near the tips of the finest roots. You see that the large, coarse +roots that you are familiar with have nothing to do with _absorbing_ +plant food from the soil. They serve merely to _conduct_ the sap and +nourishment from the root-hairs to the tree. + +When you apply manure or other fertilizer to a tree, remember that it is +far better to supply the fertilizer to the roots that are at some +distance from the trunk, for such roots are the real feeders. The plant +food in the manure soaks into the soil and immediately reaches the +root-hairs. You can understand this better by studying the distribution +of the roots of an orchard tree, shown in Fig. 19. There you can see +that the fine tips are found at a long distance from the main trunk. + +[Illustration: FIG. 18. A ROOT-HAIR WITH PARTICLES OF SOIL STICKING +TO IT] + +You can now readily see why it is that plants usually wilt when they are +transplanted. The fine, delicate root-hairs are then broken off, and the +plant can but poorly keep up its food and water supply until new hairs +have been formed. While these are forming, water has been evaporating +from the leaves, and consequently the plant does not get enough moisture +and therefore droops. + +[Illustration: FIG. 19. DISTRIBUTION OF APPLE-TREE ROOTS] + +Would you not conclude that it is very poor farming to till deeply any +crop after the roots have extended between the rows far enough to be cut +by the plow or cultivator? In cultivating between corn rows, for +example, if you find that you are disturbing fine roots, you may be sure +that you are breaking off millions of root-hairs from each plant and +hence are doing harm rather than good. Fig. 20 shows how the roots from +one corn row intertangle with those of another. You see at a glance how +many of these roots would be destroyed by deep cultivation. Stirring +the upper inch of soil when the plants are well grown is sufficient +tillage and does no injury to the roots. + +[Illustration: FIG. 20. CORN ROOTS REACH FROM ROW TO ROW] + +A deep soil is much better than a shallow soil, as its depth makes it +just so much easier for the roots to seek deep food. Fig. 21 illustrates +well how far down into the soil the alfalfa roots go. + +[Illustration: FIG. 21 ALFALFA ROOT] + + + =EXERCISE= + + Dig up the roots of several cultivated plants and weeds and compare + them. Do you find some that are fine or fibrous? some fleshy like + the carrot? The dandelion is a good example of a tap-root. + Tap-roots are deep feeders. Examine very carefully the roots of a + medium-sized corn plant. Sift the dirt away gently so as to loosen + as few roots as possible. How do the roots compare in area with the + part above the ground? Try to trace a single root of the corn plant + from the stalk to its very tip. How long are the roots of mature + plants? Are they deep or shallow feeders? Germinate some oats or + beans in a glass-sided box, as suggested, and observe the + root-hairs. + + +SECTION IX. HOW THE PLANT FEEDS FROM THE SOIL + +Plants receive their nourishment from two sources--from the air and from +the soil. The soil food, or mineral food, dissolved in water, must reach +the plant through the root-hairs with which all plants are provided in +great numbers. Each of these hairs may be compared to a finger reaching +among the particles of earth for food and water. If we examine the +root-hairs ever so closely, we find no holes, or openings, in them. It +is evident, then, that no solid particles can enter the root-hairs, but +that all food must pass into the root in solution. + +An experiment just here will help us to understand how a root feeds. + +[Illustration: FIG. 22. EXPERIMENT TO SHOW HOW ROOTS TAKE UP FOOD] + + + =EXPERIMENT= + + Secure a narrow glass tube like the one in Fig. 22. If you cannot + get a tube, a narrow, straight lamp-chimney will, with a little + care, do nearly as well. From a bladder made soft by soaking, cut a + piece large enough to cover the end of the tube or chimney and to + hang over a little all around. Make the piece of bladder secure to + the end of the tube by wrapping tightly with a waxed thread, as at + B. Partly fill the tube with molasses (or it may be easier in case + you use a narrow tube to fill it before attaching the bladder). Put + the tube into a jar or bottle of water so placed that the level of + the molasses inside and the water outside will be the same. Fasten + the tube in this position and observe it frequently for three or + four hours. At the end of the time you should find that the + molasses in the tube has risen above the level of the liquid + outside. It may even overflow at the top. If you use the + lamp-chimney the rise will not be so clearly seen, since a greater + volume is required to fill the space in the chimney. This increase + in the contents of the tube is due to the entrance of water from + the outside. The water has passed through the thin bladder, or + membrane, and has come to occupy space in the tube. There is also a + passage the other way, but the molasses can pass through the + bladder membrane so slowly that the passage is scarcely noticeable. + There are no holes, or openings, in the membrane, but still there + is a free passage of liquids in both directions, although the more + heavily laden solution must move more slowly. + +A root-hair acts in much the same way as the tube in our experiment, +with the exception that it is so made as to allow certain substances to +pass in only one direction, that is, toward the inside. The outside of +the root-hair is bathed in solutions rich in nourishment. The +nourishment passes from the outside to the inside through the delicate +membrane of the root-hair. Thus does food enter the plant-root. From the +root-hairs, foods are carried to the inside of the root. + +From this you can see how important it is for a plant to have fine, +loose soil for its root-hairs; also how necessary is the water in the +soil, since the food can be used only when it is dissolved in water. + +This passage of liquids from one side of a membrane to another is called +_osmosis_. It has many uses in the plant kingdom. We say a root takes +nourishment by osmosis. + + +SECTION X. ROOT-TUBERCLES + +Tubercle is a big word, but you ought to know how to pronounce it and +what is meant by root-tubercles. We are going to tell you what a +root-tubercle is and something about its importance to agriculture. When +you have learned this, we are sure you will want to examine some plants +for yourself in order that you may see just what tubercles look like on +a real root. + +Root-tubercles do not form on all kinds of plants that farmers grow. +They are formed only on those kinds that botanists call _legumes_. The +clovers, cowpeas, vetches, soy beans, and alfalfa are all legumes. The +tubercles are little knotty, wart-like growths on the roots of the +plants just named. These tubercles are caused by tiny forms of life +called, as you perhaps already know, bacteria, or _germs_. + +[Illustration: FIG. 23. TUBERCLES ON CLOVER ROOTS +The specimen at the right was grown in soil inoculated with soil from an +old clover field. The one at the left was grown in soil not inoculated] + +Instead of living in nests in trees like birds or in the ground like +moles and worms, these tiny germs, less than one twenty-five thousandth +of an inch long, make their homes on the roots of legumes. Nestling +snugly together, they live, grow, and multiply in their sunless homes. +Through their activity the soil is enriched by the addition of much +nitrogen from the air. They are the good fairies of the farmer, and no +magician's wand ever blessed a land so much as these invisible folk +bless the land that they live in. + +Just as bees gather honey from the flowers and carry it to the hives, +where they prepare it for their own future use and for the use of +others, so do these root-tubercles gather nitrogen from the air and fix +it in their root homes, where it can be used by other crops. + +[Illustration: FIG. 24. SOY BEANS AND COWPEAS, TWO GREAT SOIL-IMPROVERS] + +In the earlier pages of this book you were told something about the food +of plants. One of the main elements of plant food, perhaps you remember, +is nitrogen. Just as soon as the roots of the leguminous plants begin to +push down into the soil, the bacteria, or germs that make the tubercles, +begin to build their homes on the roots, and in so doing they add +nitrogen to the soil. You now see the importance of growing such crops +as peas and clover on your land, for by their tubercles you can +constantly add plant food to the soil. Now this much-needed nitrogen is +the most costly part of the fertilizers that farmers buy every year. If +every farmer, then, would grow these tubercle-bearing crops, he would +rapidly add to the richness of his land and at the same time escape the +necessity of buying so much expensive fertilizer. + + + =EXPERIMENT= + + Take a spade or shovel and dig carefully around the roots of a + cowpea and a clover plant; loosen the earth thoroughly and then + pull the plants up, being careful not to break off any of the + roots. Now wash the roots, and after they become dry count the + nodules, or tubercles, on them. Observe the difference in size. How + are they arranged? Do all leguminous plants have equal numbers of + nodules? How do these nodules help the farmer? + + +SECTION XI. THE ROTATION OF CROPS + +Doubtless you know what is meant by rotation, for your teacher has +explained to you already how the earth rotates, or turns, on its axis +and revolves around the sun. When we speak of crop-rotation we mean not +only that the same crop should not be planted on the same land for two +successive years but that crops should follow one another in a regular +order. + +Many farmers do not follow a system of farming that involves a change of +crops. In some parts of the country the same fields are planted to corn +or wheat or cotton year after year. This is not a good practice and +sooner or later will wear out the soil completely, because the +soil-elements that furnish the food of that constant crop are soon +exhausted and good crop-production is no longer possible. + +Why is crop-rotation so necessary? There are different kinds of plant +food in the soil. If any one of these is used up, the soil of course +loses its power to feed plants properly. Now each crop uses more of some +of the different kinds of foods than others do, just as you like some +kinds of food better than others. But the crop cannot, as you can, learn +to use the kinds of food it does not like; it must use the kind that +nature fitted it to use. Not only do different crops feed upon different +soil foods, but they use different quantities of these foods. + +Now if a farmer plant the same crop in the same field each year, that +crop soon uses up all of the available plant food that it likes. Hence +the soil can no longer properly nourish the crop that has been year by +year robbing it. If that crop is to be successfully grown again on the +land, the exhausted element must be restored. + +[Illustration: FIG. 25. GRASS FOLLOWING CORN] + +This can be done in two ways: first, by finding out what element has +here been exhausted, and then restoring this element by means either of +commercial fertilizers or manure; second, by planting on the land crops +that feed on different food and that will allow or assist kind Mother +Nature "to repair her waste places." An illustration may help you to +remember this fact. Nitrogen is, as already explained, one of the +commonest plant foods. It may almost be called plant bread. The wheat +crop uses up a good deal of nitrogen. Suppose a field were planted in +wheat year after year. Most of the available nitrogen would be taken out +of the soil after a while, and a new wheat crop, if planted on the +field, would not get enough of its proper food to yield a paying +harvest. This same land, however, that could not grow wheat could +produce other crops that do not require so much nitrogen. For example, +it could grow cowpeas. Cowpeas, aided by their root-tubercles, are able +to gather from the air a great part of the nitrogen needed for their +growth. Thus a good crop of peas can be obtained even if there is little +available nitrogen in the soil. On the other hand wheat and corn and +cotton cannot use the free nitrogen of the air, and they suffer if there +is an insufficient quantity present in the soil; hence the necessity of +growing legumes to supply what is lacking. + +[Illustration: FIG. 26. COWPEAS AND CORN--AUGUST] + +Let us now see how easily plant food may be saved by the rotation of +crops. + +If you sow wheat in the autumn it is ready to be harvested in time for +planting cowpeas. Plow or disk the wheat stubble, and sow the same field +to cowpeas. If the wheat crop has exhausted the greater part of the +nitrogen of the soil, it makes no difference to the cowpea; for the +cowpea will get its nitrogen from the air and not only provide for its +own growth but will leave quantities of nitrogen in the queer nodules of +its roots for the crops coming after it in the rotation. + +[Illustration: FIG. 27. COWPEAS AND CORN--OCTOBER] + +If corn be planted, there should be a rotation in just the same way. The +corn plant, a summer grower, of course uses a certain portion of the +plant food stored in the soil. In order that the crop following the corn +may feed on what the corn did not use, this crop should be one that +requires a somewhat different food. Moreover, it should be one that fits +in well with corn so as to make a winter crop. We find just such a +plant in clover or wheat. Like the cowpea, all the varieties of clover +have on their roots tubercles that add the important element, nitrogen, +to the soil. + +From these facts is it not clear that if you wish to improve your land +quickly and keep it always fruitful you must practice crop-rotation? + + +AN ILLUSTRATION OF CROP-ROTATION + +Here are two systems of crop-rotation as practiced at one or more +agricultural experiment stations. Each furnishes an ideal plan for +keeping up land. + + ---------------------++----------------------++---------------------- + ---------------------++----------------------++---------------------- + FIRST YEAR || SECOND YEAR || THIRD YEAR + ----------+----------++-----------+----------++-----------+---------- + Summer | Winter || Summer | Winter || Summer | Winter + ----------+----------++-----------+----------++-----------+---------- + Corn | Crimson || Cotton | Wheat || Cowpeas | Rye for + | clover || | || | pasture + ----------+----------++-----------+----------++-----------+---------- + + or + + ----------+----------++-----------+----------++-----------+---------- + Summer | Winter || Summer | Winter || Summer | Winter + ----------+----------++-----------+----------++-----------+---------- + Corn | Wheat || Clover | Clover || Grass | Grass for + | || and grass | and grass|| |pasture or + | || | || | meadow + ----------+----------++-----------+----------++-----------+---------- + ----------+----------++-----------+----------++-----------+---------- + +In these rotations the cowpeas and clovers are nitrogen-gathering crops. +They not only furnish hay but they enrich the soil. The wheat, corn, and +cotton are money crops, but in addition they are cultivated crops; hence +they improve the physical condition of the soil and give opportunity to +kill weeds. The grasses and clovers are of course used for pasturage and +hay. This is only a suggested rotation. Work out one that will meet your +home need. + + + =EXERCISE= + + Let the pupils each present a system of rotation that includes the + crops raised at home. The system presented should as nearly as + possible meet the following requirements: + + 1. Legumes for gathering nitrogen. + 2. Money crops for cash income. + 3. Cultivated crops for tillage and weed-destruction. + 4. Food crops for feeding live stock. + + + + +CHAPTER III + +THE PLANT + + +SECTION XII. HOW A PLANT FEEDS FROM THE AIR + +If you partly burn a match you will see that it becomes black. This +black substance into which the match changes is called _carbon_. Examine +a fresh stick of charcoal, which is, as you no doubt know, burnt wood. +You see in the charcoal every fiber that you saw in the wood itself. +This means that every part of the plant contains carbon. How important, +then, is this substance to the plant! + +You will be surprised to know that the total amount of carbon in plants +comes from the air. All the carbon that a plant gets is taken in by the +leaves of the plant; not a particle is gathered by the roots. A large +tree, weighing perhaps 11,000 pounds, requires in its growth carbon from +16,000,000 cubic yards of air. + +Perhaps, after these statements, you may think there is danger that the +carbon of the air may sometime become exhausted. The air of the whole +world contains about 1,760,000,000,000 pounds of carbon. Moreover, this +is continually being added to by our fires and by the breath of animals. +When wood or coal is used for fuel the carbon of the burning substance +is returned to the air in the form of gas. Some large factories burn +great quantities of coal and thus turn much carbon back to the air. A +single factory in Germany is estimated to give back to the air daily +about 5,280,000 pounds of carbon. You see, then, that carbon is +constantly being put back into the air to replace that which is used by +growing plants. + +The carbon of the air can be used by none but green plants, and by them +only in the sunlight. We may compare the green coloring matter of the +leaf to a machine, and the sunlight to the power, or energy, which keeps +the machine in motion. By means, then, of sunlight and the green +coloring matter of the leaves, the plant secures carbon. The carbon +passes into the plant and is there made into two foods very necessary to +the plant; namely, starch and sugar. + +Sometimes the plant uses the starch and sugar immediately. At other +times it stores both away, as it does in the Irish and the sweet potato +and in beets, cabbage, peas, and beans. These plants are used as food by +man because they contain so much nourishment; that is, starch and sugar +which were stored away by the plant for its own future use. + + + =EXERCISE= + + Examine some charcoal. Can you see the rings of growth? Slightly + char paper, cloth, meat, sugar, starch, etc. What does the turning + black prove? What per cent of these substances do you think is pure + carbon? + + +SECTION XIII. THE SAP CURRENT + +The root-hairs take nourishment from the soil. The leaves manufacture +starch and sugar. These manufactured foods must be carried to all parts +of the plant. There are two currents to carry them. One passes from the +roots through the young wood to the leaves, and one, a downward current, +passes through the bark, carrying needed food to the roots (see Fig. +28). + +If you should injure the roots, the water supply to the leaves would be +cut off and the leaves would immediately wither. On the other hand, if +you remove the bark, that is, girdle the tree, you in no way interfere +with the water supply and the leaves do not wither. Girdling does, +however, interfere with the downward food current through the bark. + +[Illustration: FIG. 28 MOVEMENT OF THE SAP CURRENT] + +If the tree be girdled the roots sooner or later suffer from lack of +food supply from the leaves. Owing to this food stoppage the roots will +cease to grow and will soon be unable to take in sufficient water, and +then the leaves will begin to droop. This, however, may not happen until +several months after the girdling. Sometimes a partly girdled branch +grows much in thickness just above the girdle, as is shown in Fig. 29. +This extra growth seems to be due to a stoppage of the rich supply of +food which was on its way to the roots through the bark. It could go no +farther and was therefore used by the tree to make an unnatural growth +at this point. You will now understand how and why trees die when they +are girdled to clear new ground. + +[Illustration: FIG. 29. A THICKENING ABOVE THE WIRE THAT CAUSED THE +GIRDLING] + +It is, then, the general law of sap-movement that the upward current +from the roots passes through the woody portion of the trunk, and that +the current bearing the food made by the leaves passes downward through +the bark. + + + =EXERCISE= + + Let the teacher see that these and all other experiments are + performed by the pupils. Do not allow them to guess, but make them + see. + + Girdle valueless trees or saplings of several kinds, cutting the + bark away in a complete circle around the tree. Do not cut into the + wood. How long before the tree shows signs of injury? Girdle a + single small limb on a tree. What happens? Explain. + + +SECTION XIV. THE FLOWER AND THE SEED + +Some people think that the flowers by the wayside are for the purpose of +beautifying the world and increasing man's enjoyment. Do you think this +is true? Undoubtedly a flower is beautiful, and to be beautiful is one +of the uses of many flowers; but it is not the chief use of a flower. + +You know that when peach or apple blossoms are nipped by the spring +frost the fruit crop is in danger. The fruit of the plant bears the +seed, and the flower produces the fruit. That is its chief duty. + +[Illustration: FIG. 30. PARTS OF THE PISTIL] + +Do you know any plant that produces seed without flowers? Some one +answers, "The corn, the elm, and the maple all produce seed, but have no +flower." No, that is not correct. If you look closely you will find in +the spring very small flowers on the elm and on the maple, while the ear +and the tassel are really the blossoms of the corn plant. Every plant +that produces seed has flowers, although they may sometimes seem very +curious flowers. + +[Illustration: FIG. 31. A BUTTERCUP] + +Let us see what a flower really is. Take, for example, a buttercup, +cotton, tobacco, or plum blossom (see Figs. 31 and 32). You will find on +the outside a row of green leaves inclosing the flower when it is still +a bud. These leaves are the _sepals_. Next on the inside is a row of +colored leaves, or _petals_. Arranged inside of the petals are some +threadlike parts, each with a knob on the end. These are the _stamens_. +Examine one stamen closely (Fig. 33). On the knob at its tip you should +find, if the flower is fully open, some fine grains, or powder. In the +lily this powder is so abundant that in smelling the flower you often +brush a quantity of it off on your nose. This substance is called +_pollen_, and the knob on the end of the stamen, on which the pollen is +borne, is the _anther_. + +[Illustration: FIG. 32. A PLUM BLOSSOM] + +The pollen is of very great importance to the flower. Without it there +could be no seeds. The stamens as pollen-bearers, then, are very +important. But there is another part to each flower that is of equal +value. This part you will find in the center of the flower, inside the +circle of stamens. It is called the _pistil_ (Fig. 32). The swollen tip +of the pistil is the _stigma_. The swollen base of the pistil forms the +_ovary_. If you carefully cut open this ovary you will find in it +very small immature seeds. + +[Illustration: FIG. 33. STAMENS +_a_, anther; _f_, filament] + +Some plants bear all these parts in the same flower; that is, each +blossom has stamens, pistil, petals, and sepals. The pear blossom and +the tomato blossom represent such flowers. Other plants bear their +stamens and pistils in separate blossoms. Stamens and pistils may even +occur in separate plants, and some blossoms have no sepals or petals at +all. Look at the corn plant. Here the tassel is a cluster of many +flowers, each of which bears only stamens. The ear is likewise a cluster +of many flowers, each of which bears only a pistil. The dust that you +see falling from the tassel is the pollen, and the long silky threads of +the ear are the stigmas. + +[Illustration: FIG. 34. A TOMATO BLOSSOM] + +Now no plant can bear seeds unless the pollen of the stamen falls on the +stigma. Corn cannot therefore form seed unless the dust of the tassel +falls upon the silk. Did you ever notice how poorly the cob is filled on +a single cornstalk standing alone in a field? Do you see why? It is +because when a plant stands alone the wind blows the pollen away from +the tassel, and little or none is received on the stigmas below. + +[Illustration: FIG. 35. CUCUMBER BLOSSOMS] + +In the corn plant the stamens and pistils are separate; that is, they do +not occur on the same flower, although they are on the same plant. This +is also true of the cucumber (see Fig. 35). In many plants, however, +such as the hemp, hop, sassafras, willow, and others, the staminate +parts are on one plant and the pistillate parts are on another. This is +also true in several other cultivated plants. For example, in some +strawberries the stamens are absent or useless; that is, they bear no +good pollen. In such cases the grower must see to it that near by are +strawberry plants that bear stamens, in order that those plants which do +not bear pollen may become _pollinated_; that is, may have pollen +carried to them. After the stigma has been supplied with pollen, a +single pollen grain sends a threadlike sprout down through the stigma +into the ovary. This process, if successfully completed, is called +_fertilization_. + + + =EXERCISE= + + Examine several flowers and identify the parts named in the last + section. Try in the proper season to find the pollen on the maple, + willow, alder, and pine, and on wheat, cotton, and the + morning-glory. + + How fast does the ovary of the apple blossom enlarge? Measure one + and watch it closely from day to day. Can you find any plants that + have their stamens and ovaries on separate individuals? + + +SECTION XV. POLLINATION + +Nature has several interesting ways of bringing about pollination. In +the corn, willow, and pine the pollen is picked up by the wind and +carried away. Much of it is lost, but some reaches the stigmas, or +receptive parts, of other corn, willow, or pine flowers. This is a very +wasteful method, and all plants using it must provide much pollen. + +Many plants employ a much better method. They have learned how to make +insects bear their pollen. In plants of this type the parts of the +blossom are so shaped and so placed as to deposit pollen from the stamen +on the insect and to receive pollen from the insect on the stigmas. + +When you see the clumsy bumblebee clambering over and pushing his way +into a clover blossom, you may be sure that he is getting well dusted +with pollen and that the next blossom which he visits will secure a full +share on its stigmas. + +When flowers fit themselves to be pollinated by insects they can no +longer use the wind and are helpless if insects do not visit them. They +therefore cunningly plan two ways to invite the visits of insects. +First, they provide a sweet nectar as a repast for the insect visitor. +The nectar is a sugary solution found in the bottom of the flower and is +used by the visitor as food or to make honey. Second, flowers advertise +to let each insect know that they have something for it. The advertising +is done either by showy colors or by perfume. Insects have wonderful +powers of smell. When you see showy flowers or smell fragrant ones, you +will know that such flowers are advertising the presence either of +nectar or of pollen (to make beebread) and that such flowers depend on +insects for pollination. + +[Illustration: FIG. 36. BEES CARRYING POLLEN] + +A season of heavy, cold rains during blossoming-time may often injure +the fruit crop by preventing insects from carrying pollen from flower to +flower. You now also understand why plants often fail to produce seeds +indoors. Since they are shut in, they cannot receive proper insect +visits. Plants such as tomatoes or other garden fruits dependent upon +insect pollination must, if raised in the greenhouse where insects +cannot visit them, be pollinated by hand. + + + =EXERCISE= + + Exclude insect visitors from some flower or flower cluster, for + example, clover, by covering with a paper bag, and see whether the + flower can produce seeds that are capable of growing. Compare as to + number and vitality the seeds of such a flower with those of an + uncovered flower. Observe insects closely. Do you ever find pollen + on them? What kinds of insects visit the clover? the cowpea? the + sourwood? the flax? Is wheat pollinated by insects or by the wind + or by some other means? Do bees fly in rainy weather? How will a + long rainy season at blossoming-time affect the apple crop? Why? + Should bees be kept in an orchard? Why? + + +SECTION XVI. CROSSES, HYBRIDS, AND CROSS-POLLINATION + +In our study of flowers and their pollination we have seen that the seed +is usually the descendant of two parents, or at least of two organs--one +the ovary, producing the seed; the other the pollen, which is necessary +to fertilize the ovary. + +It happens that sometimes the pollen of one blossom fertilizes the ovary +of its own flower, but more often the pollen from one plant fertilizes +the ovary of another plant. This latter method is called +_cross-pollination_. As a rule cross-pollination makes seed that will +produce a better plant than simple pollination would. Cross-pollination +by hand is often used by plant-breeders when, for purposes of +seed-selection, a specially strong plant is desired. The steps in hand +pollination are as follows: (1) remove the anthers before they open, to +prevent them from pollinating the stigma (the steps in this process are +illustrated in Figs. 37, 38-39); (2) cover the flower thus treated with +a paper bag to prevent stray pollen from getting on it (see Fig. 40); +(3) when the ovary is sufficiently developed, carry pollen to the stigma +by hand from the anthers of another plant which you have selected to +furnish it, and rebag to keep out any stray pollen which might +accidentally get in; (4) collect the seeds when they are mature and +label them properly. + +Hand pollination has this advantage--you know both parents of your seed. +If pollination occur naturally you know the maternal but have no means +of judging the paternal parent. You can readily see, therefore, how hand +pollination enables you to secure seed derived from two well-behaved +parents. + +Sometimes we can breed one kind of plant on another. The result of such +cross-breeding is known as a _hybrid_. In the animal kingdom the mule is +a common example of this cross-breeding. Plant hybrids were formerly +called mules also, but this suggestive term is almost out of use. + +[Illustration: FIG. 37 +The bud on right at top is in proper condition for removal of anthers; +the anthers have been removed from the buds below] + +It is only when plants of two distinct kinds are crossed that the result +is called a hybrid; for example, a blackjack oak on a white oak, an +apple on a pear. If the parent plants are closely related, for example, +two kinds of apples, the resulting plant is known simply as a _cross_. + +Hybrids and crosses are valuable in that they usually differ from both +parents and yet combine some qualities of each. + +[Illustration: FIG. 38. ORANGE BLOSSOM PREPARED FOR CROSSING +First, bud; second, anthers unremoved; third, anthers removed] + +[Illustration: FIG. 39. TOMATO BLOSSOM READY TO CROSS +First, bud; second, anthers unremoved; third, anthers removed] + +[Illustration: FIG. 40. +First, blossom bagged to keep out stray pollen; second, fruit bagged for +protection] + +They often leave off some of the qualities of the parent +plants and at other times have such qualities more markedly than did +their parents. Thus they often produce an interesting new kind of plant. +Sometimes we are able by hybridization to combine in one plant the good +qualities of two other plants and thus make a great advance in +agriculture. The new forms brought about by hybridization may be fixed, +or made permanent, by such selection as is mentioned in Section XVIII. +Hybridization is of great aid in originating new plants. + +It often happens that a plant will be more fruitful when pollinated by +one variety than by some other variety. This is well illustrated in Fig. +41. A fruit-grower or farmer should know much about these subjects +before selecting varieties for his orchard, vineyard, etc. + + + =EXERCISE= + + With the help of your teacher try to cross some plants. Such an + experiment will take time, but will be most interesting. You must + remember that many crosses must be attempted in order to gain + success with even a few. + + +SECTION XVII. PROPAGATION BY BUDS + +It is the business of the farmer to make plants grow, or, as it is +generally called, to propagate plants. This he does in one of two ways: +by buds (that is, by small pieces cut from parent plants), or by seeds. +The chief aim in both methods should be to secure in the most convenient +manner the best-paying plants. + +Many plants are most easily and quickly propagated by buds; for example, +the grape, red raspberry, fig, and many others that we cultivate for the +flower only, such as the carnation, geranium, rose, and begonia. + +[Illustration: FIG. 41. +Brighton pollinated by 1, Salem; 2, Creveling; 3, Lindley; 4, Brighton; +5, Self-pollinated; 6, Nectar; 7, Jefferson; 8, Niagara] + +In growing plants from cuttings, a piece is taken from the kind of plant +that one wishes to grow. The greatest care must be exercised in order to +get a healthy cutting. If we take a cutting from a poor plant, what can +we expect but to grow a poor plant like the one from which our cutting +was taken? On the other hand, if a fine, strong, vigorous, fruitful +plant be selected, we shall expect to grow just such a fine, healthy, +fruitful plant. + +We expect the cutting to make exactly the same variety of plant as the +parent stock. We must therefore decide on the variety of berry, grape, +fig, carnation, or rose that we wish to propagate, and then look for the +strongest and most promising plants of this variety within our reach. +The utmost care will not produce a fine plant if we start from poor +stock. + +[Illustration: FIG. 42. GERANIUM CUTTING +Dotted line shows depth to which cutting should be planted] + +What qualities are most desirable in a plant from which cuttings are to +be taken? First, it should be productive, hardy, and suited to your +climate and your needs; second, it should be healthy. Do not take +cuttings from a diseased plant, since the cutting may carry the +disease. + +Cuttings may be taken from various parts of the plant, sometimes even +from parts of the leaf, as in the begonia (Fig. 46). More often, +however, they are drawn from parts of the stem (Figs. 43-45). As to the +age of the twig from which the cutting is to be taken, Professor Bailey +says: "For most plants the proper age or maturity of wood for the making +of cuttings may be determined by giving the twig a quick bend; if it +snaps and hangs by the bark, it is in proper condition. If it bends +without breaking, it is too young and soft or too old. If it splinters, +it is too old and woody." Some plants, as the geranium (Fig. 42), +succeed best if the cuttings from which they are grown are taken from +soft, young parts of the plant; others, for example, the grape or rose, +do better when the cutting is made from more mature wood. + +[Illustration: FIG. 43 GRAPE CUTTING +Showing depth to which cutting should be planted] + +[Illustration: FIG. 44. CARNATION CUTTING] + +Cuttings may vary in size and may include one or more buds. After a +hardy, vigorous cutting is made, insert it about one half or one third +of its length in soil. A soil free from organic matter is much the best, +since in such soil the cuttings are much less liable to disease. A fine, +clean sand is commonly used by professional gardeners. When cuttings +have rooted well--this may require a month or more--they may be +transplanted to larger pots. + +Sometimes, instead of cutting off a piece and rooting it, portions of +branches are made to root before they are separated from the parent +plant. This method is often followed, and is known as _layering_. It is +a simple process. Just bend the tip of a bough down and bury it in the +earth (see Fig. 47). The black raspberry forms layers naturally, but +gardeners often aid it by burying the over-hanging tips in the earth, so +that more tips may easily take root. Strawberries develop runners that +root themselves in a similar fashion. + +Grafts and buds are really cuttings which, instead of being buried in +sand to produce roots of their own, are set on the roots of other +plants. + +[Illustration: FIG. 45. ROSE CUTTING] + +Grafting and budding are practiced when these methods are more +convenient than cuttings or when the gardener thinks there is danger of +failure to get plants to take root as cuttings. Neither grafting nor +budding is, however, necessary for the raspberry or the grape, for these +propagate most readily from cuttings. + +It is often the case that a budded or grafted plant is more fruitful +than a plant on its own roots. In cases of this kind, of course, grafts +or buds are used. + +The white, or Irish, potato is usually propagated from pieces of the +potato itself. Each piece used for planting bears one eye or more. The +potato itself is really an underground stem and the eyes are buds. This +method of propagation is therefore really a peculiar kind of cutting. + +Since the eye is a bud and our potato plant for next year is to develop +from this bud, it is of much importance, as we have seen, to know +exactly what _kind_ of plant our potato comes from. If the potato is +taken from a small plant that had but a few poor potatoes in the hill, +we may expect the bud to produce a similar plant and a correspondingly +poor crop. We must see to it, then, that our seed potatoes are drawn +from vines that were good producers, because new potato plants are like +the plants from which they were grown. Of course when our potatoes are +in the bin we cannot tell from what kind of plants they came. We must +therefore _select our seed potatoes in the field_. Seed potatoes should +always be selected from those hills that produce most bountifully. Be +assured that the increased yield will richly repay this care in +selecting. It matters not so much whether the seed potato be large or +small; it must, however, come from a hill bearing a large yield of fine +potatoes. + +[Illustration: FIG. 46. BEGONIA-LEAF CUTTING] + +Sweet-potato plants are produced from shoots, or growing buds, taken +from the potato itself, so that in their case too the piece that we use +in propagating is a part of the original plant, and will therefore be +like it under similar conditions. Just as with the Irish potato, it is +important to know how good a yielder you are planting. You should watch +during harvest and select for propagation for the next year only such +plants as yield best. + +We should exercise fully as much care in selecting proper individuals +from which to make a cutting or a layer as we do in selecting a proper +animal to breed from. Just as we select the finest Jersey in the herd +for breeding purposes, so we should choose first the variety of plant we +desire and then the finest individual plant of that variety. + +If the variety of the potato that we desire to raise be Early Rose, it +is not enough to select _any_ Early Rose plants, but the very best Early +Rose plants, to furnish our seed. + +[Illustration: FIG. 47. LAYERING] + +It is not enough to select large, fine potatoes for cuttings. A large +potato may not produce a bountifully yielding plant. _It will produce a +plant like the one that produced it._ It may be that this one large +potato was the only one produced by the original plant. If so, the plant +that grows from it will tend to be similarly unproductive. Thus you see +the importance of _selecting in the field a plant that has exactly the +qualities desired in the new plant_. + +One of the main reasons why gardeners raise plants from buds instead of +from seeds is that the seed of many plants will not produce plants like +the parent. This failure to "come true," as it is called, is sometimes +of value, for it occasionally leads to improvement. For example, suppose +that a thousand apple or other fruit or flower seeds from plants usually +propagated by cuttings be planted; it may be that one out of a thousand +or a million will be a very valuable plant. If a valuable plant be so +produced, it should be most carefully guarded, multiplied by cuttings or +grafts, and introduced far and wide. It is in this way that new +varieties of fruits and flowers are produced from time to time. + +Sometimes, too, a single bud on a tree will differ from the other buds +and will produce a branch different from the other branches. This is +known as _bud variation_. When there is thus developed a branch which +happens to be of a superior kind, it should be propagated by cuttings +just as you would propagate it if it had originated from a seed. + +[Illustration: FIG. 48. CURRANT CUTTING] + +Mr. Gideon of Minnesota planted many apple seeds, and from them all +raised one tree that was very fruitful, finely flavored, and able to +withstand the cold Minnesota winter. This tree he multiplied by grafts +and named the Wealthy apple. It is said that in giving this one apple to +the world he benefited mankind to the value of more than one million +dollars. It will be well to watch for any valuable bud or seed variant +and never let a promising one be lost. Plants grown in this way from +seeds are usually spoken of as seedlings. + +[Illustration: A LUSCIOUS AND EASILY GROWN BERRY] + + +PLANTS TO BE PROPAGATED FROM BUDS + +The following list gives the names and methods by which our common +garden fruits and flowers are propagated: + + _Figs_: use cuttings 8 to 10 inches long or layer. + _Grapes_: use long cuttings, layer, or graft upon old vines. + + _Apples_: graft upon seedlings, usually crab seedlings one + year old. + + _Pears_: bud upon pear seedlings. + + _Cherries_: bud upon cherry stock. + + _Plums_: bud upon peach stock. + + _Peaches_: bud upon peach or plum seedlings. + + _Quinces_: use cuttings or layer. + + _Blackberries_: propagate by suckers; cut from parent stem. + + _Black raspberries_: layer; remove old stem. + + _Red raspberries_: propagate by root-cuttings or suckers. + + _Strawberries_: propagate by runners. + + _Currants_ and _gooseberries_: use long cuttings (these plants + grow well only in cool climates; if attempted in warm + climates, set in cold exposure). + + _Carnations_, _geraniums_, _roses_, _begonias_, etc.: propagate by + cuttings rooted in sand and then transplanted to small pots. + + =EXERCISE= + + Propagate fruits (grape, fig, strawberry) of various kinds; also + ornamental plants. How long does it take them to root? Geraniums + rooted in the spring will bloom in the fall. Do you know any one + who selects seed potatoes properly? Make a careful selection of + seed at the next harvest-time. + + +SECTION XVIII. PLANT SEEDING + +In propagating by seed, as in reproducing by buds, we select a portion +of the parent plant--for a seed is surely a part of the parent +plant--and place it in the ground. There is, however, one great +difference between a seed and a bud. The bud is really a piece of the +parent plant, but a piece of _one_ plant only, while a seed comes from +the parts of two plants. + +You will understand this fully if you read carefully Sections XIV-XVI. +Since the seed is made of two plants, the plant that springs from a seed +is much more likely to differ from its mother plant, that is, from the +plant that produces the seed, than is a plant produced merely by buds. +In some cases plants "come true to seed" very accurately. In others they +vary greatly. For example, when we plant the seed of wheat, turnips, +rye, onions, tomatoes, tobacco, or cotton, we get plants that are in +most respects like the parent plant. On the other hand the seed of a +Crawford peach or a Baldwin apple or a Bartlett pear will not produce +plants like its parent, but will rather resemble its wild forefathers. +These seedlings, thus taking after their ancestors, are always far +inferior to our present cultivated forms. In such cases seeding is not +practicable, and we must resort to bud propagation of one sort or +another. + +While in a few plants like those just mentioned the seed does not "come +true," most plants, for example, cotton, tobacco, and others, do "come +true." When we plant King cotton we may expect to raise King cotton. +There will be, however, as every one knows, some or even considerable +variation in the field. Some plants, even in exactly the same soil, will +be better than the average, and some will be poorer. Now we see this +variation in the plants of our field, and we believe that the plant will +be in the main like its parent. What should we learn from this? Surely +that if we wish to produce sturdy, healthy, productive plants we must go +into our fields and _pick out just such plants to secure seed from as we +wish to produce another year_. If we wait until the seed is separated +from the plant that produced it before we select our cotton seed, we +shall be planting seed from poor as well as from good plants, and must +be content with a crop of just such stock as we have planted. By +selecting seed from the most productive plants _in the field_ and by +repeating the selection each year, you can continually improve the breed +of the plant you are raising. In selecting seed for cotton you may +follow the plan suggested below for wheat. + +[Illustration: FIGS. 49 AND 50. CHRYSANTHEMUMS AND ASPARAGUS] + +The difference that you see between the wild and the cultivated +chrysanthemums and between the samples of asparagus shown in Figs. 49 +and 50 was brought about by just such continuous seed-selection from the +kind of plant wanted. + +[Illustration: FIG. 51. TWO VARIETIES OF FLAX FROM ONE PARENT STOCK] + +By the careful selection of seed from the longest flax plants the +increase in length shown in the accompanying figure was gained. The +selection of seed from those plants bearing the most seed, regardless of +the height of the plant, has produced flax like that to the right in the +illustration. These two kinds of flax are from the same parent stock, +but slight differences have been emphasized by continued seed-selection, +until we now have really two varieties of flax, one a heavy seed-bearer, +the other producing a long fiber. + +You can in a similar way improve your cotton or any other seed crop. +Sugar beets have been made by seed-selection to produce about double the +percentage of sugar that they did a few years ago. Preparing and +tilling land costs too much in money and work to allow the land to be +planted with poor seed. When you are trying by seed-selection to +increase the yield of cotton, there are two principles that should be +borne in mind: first, seed should be chosen only from plants that bear +many well-filled bolls of long-staple cotton; second, seed should be +taken from no plant that does not by its healthy condition show +hardihood in resisting disease and drouth. + +The plan of choosing seeds from selected plants may be applied to wheat; +but it would of course be too time-consuming to select enough single +wheat plants to furnish all of the seed wheat for the next year. In this +case adopt the following plan: In Fig. 52 let _A_ represent the total +size of your wheat field and let _B_ represent a plat large enough to +furnish seed for the whole field. At harvest-time go into section _A_ +and select the best plants you can find. Pick the heads of these and +thresh them by hand. The seed so obtained must be carefully saved for +your next sowing. + +[Illustration: FIG. 52.] + +In the fall sow these selected seeds in area _B_. This area should +produce the best wheat. At the next harvest cull not from the whole +field but from the finest plants of plat _B_, and again save these as +seed for plat _B_. Use the unculled seed from plat _B_ to sow your crop. +By following this plan continuously you will every year have seed from +several generations of choice plants, and each year you will improve +your seed. + +It is of course advisable to move your seed plat _B_ every year or two. +For the new plat select land that has recently been planted in legumes. +Always give this plat unwearying care. + +In the selection of plants from which to get seed, you must know what +kind of plants are really the best seed plants. First, _you must not +regard single heads or grains, but must select seed from the most +perfect plant_, looking at the plant as a whole and not at any single +part of it. A first consideration is yield. Select the plants that yield +best and are at the same time resistant to drouth, resistant to rust and +to winter, early to ripen, plump of grain, and nonshattering. What a +fine thing it would be to find even one plant free from rust in the +midst of a rusted field! It would mean a _rust-resistant plant_. Its +offspring also would probably be rust-resistant. If you should ever find +such a plant, be sure to save its seed and plant it in a plat by itself. +The next year again save seed from those plants least rusted. Possibly +you can develop a rust-proof race of wheat! Keep your eyes open. + +In England the average yield of wheat is thirty bushels an acre, in the +United States it is less than fifteen bushels! In some states the yield +is even less than nine bushels an acre. Let us select our seed with +care, as the English people do, and then we can increase our yield. By +careful seed-selection a plant-breeder in Minnesota increased the yield +of his wheat by one fourth. Think what it would mean if twenty-five per +cent were added to the world's supply of wheat at comparatively no cost; +that is, at the mere cost of careful seed-selection. This would mean an +addition to the world's income of about $500,000,000 each year. The +United States would get about one fifth of this profit. + +It often happens that a single plant in a crop of corn, cotton, or wheat +will be far superior to all others in the field. Such a plant deserves +special care. Do not use it merely as a seed plant, but carefully plant +its seeds apart and tend carefully. The following season select the best +of its offspring as favorites again. Repeat this selection and culture +for several years until you fix the variety. This is the way new +varieties are originated from plants propagated by seed. + +In 1862 Mr. Abraham Fultz of Pennsylvania, while passing through a field +of bearded wheat, found three heads of beardless, or bald, wheat. These +he sowed by themselves that year, and as they turned out specially +productive he continued to sow this new variety. Soon he had enough seed +to distribute over the country. It became known as the Fultz wheat and +is to-day one of the best varieties in the United States and in a number +of foreign countries. Think how many bushels of wheat have been added to +the world's annual supply by a few moments of intelligent observation +and action on the part of this one man! He saw his opportunity and used +it. How many similar opportunities do you think are lost? How much does +your state or country lose thereby? + + + =EXERCISE= + + Select one hundred seeds from a good, and one hundred from a poor, + plant of the same variety. Sow them in two plats far enough apart + to avoid cross-pollination, yet try to have soil conditions about + the same. Give each the same care and compare the yield. Try this + with corn, cotton, and wheat. Select seeds from the best plant in + your good plat and from the poorest in your poor plat and repeat + the experiment. This will require but a few feet of ground, and the + good plat will pay for itself in yield, while the poor plat will + more than pay in the lesson that it will teach you. + + Write to the Department of Agriculture, Washington, D.C., and to + your state experiment station for bulletins concerning + seed-selection and methods of plant-improvement. + + +SECTION XIX. SELECTING SEED CORN + +If a farmer would raise good crops he must, as already stated, select +good seed. Many of the farmer's disappointments in the quantity and +quality of his crops--disappointments often thought to come from other +causes--are the result of planting poor seed. Seeds not fully ripened, +if they grow at all, produce imperfect plants. Good seed, therefore, is +the first thing necessary for a good crop. The seed of perfect plants +only should be saved. + +By wise and persistent selection, made in the field before the crop is +fully matured, corn can be improved in size and made to mature earlier. +Gather ears only from the most productive plants and save only the +largest and best kernels. + +[Illustration: FIG. 53. THE KIND OF EAR TO SELECT] + +You have no doubt seen the common American blackbirds that usually +migrate and feed in such large numbers. They all look alike in every +way. Now, has it ever occurred to you to ask why all blackbirds are +black? The blackbirds are black simply because their parents are black. + +Now in the same way that the young blackbirds resemble their parents, +corn will resemble its parent stock. How many ears of corn do you find +on a stalk? One, two, sometimes three or four. You find two ears of corn +on a stalk because it is the nature of that particular stalk to produce +two ears. In the same way the nature of some stalks is to produce but +one ear, while it is the nature of others sometimes to produce two or +more. + +This resemblance of offspring to parent is known to scientists as +heredity, or as "like producing like." + +Some Southern corn-breeders take advantage of this law to improve their +corn crop. If a stalk can be made to produce two ears of corn just as +large as the single ear that most stalks bear, we shall get twice as +much corn from a field in which the "two-eared" variety is planted. In +the North and West the best varieties of corn have been selected to make +but one ear to the stalk. It is generally believed that this is the best +practice for the shorter growing seasons of the colder states. + +[Illustration: FIG. 54. SELECT SEED FROM A STALK LIKE THAT ON LEFT] + +These facts ought to be very helpful to us next year when our fathers +are planting corn. We should get them to plant seed secured only from +stalks that produced the most corn, whether the stalk had two or more +ears or only one. If we follow this plan year by year, each acre of land +will be made to produce more kernels and hence a larger crop of corn, +and yet no more work will be required to raise the crop. + +In addition to enlarging the yield of corn, you can, by proper selection +of the best and most productive plants in the field, grow a new variety +of seed corn. To do this you need only take the largest and best +kernels from stalks bearing two ears; plant these, and at the next +harvest again save the best kernels from stalks bearing the best ears. +If you keep up this practice with great care for several years, you will +get a vigorous, fruitful variety that will command a high price for +seed. + + + =EXPERIMENT= + + [Illustration: FIG. 55. IMPROVEMENT OF CORN BY SELECTION + Boone County white corn on left, and original type, from which it + was developed by selection, on right] + + Every school boy and girl can make this experiment at leisure. From + your own field get two ears of corn, one from a stalk bearing only + one ear and the other from a stalk bearing two well-grown ears. + Plant the grains from one ear in one plat, and the grains from the + other in a plat of equal size. Use for both the same soil and the + same fertilizer. Cultivate both plats in the same way. When the + crop is ready to harvest, husk the corn, count the ears, and weigh + the corn. Then write a short essay on your work and on the results + and get your teacher to correct the story for your home paper. + + +SECTION XX. WEEDS + +Have you ever noticed that some weeds are killed by one particular +method, but that this same method may entirely fail to kill other kinds +of weeds? If we wish to free our fields of weeds with the greatest ease, +we must know the nature of each kind of weed and then attack it in the +way in which we can most readily destroy it. + +[Illustration: FIG. 56. PIGWEED] + +The ordinary pigweed (Fig. 56) differs from many other weeds in that it +lives for only one year. When winter comes, it must die. Each plant, +however, bears a great number of seeds. If we can prevent the plant from +bearing seed in its first year, there will not be many seeds to come up +the next season. In fact, only those seeds that were too deeply buried +in the soil to come up the previous spring will be left, and of these +two-year-old seeds many will not germinate. During the next season some +old seeds will produce plants, but the number will be very much +diminished. If care be exercised to prevent the pigweed from seeding +again, and the same watchfulness be continued for a few seasons, this +weed will be almost entirely driven from our fields. + +A plant like the pigweed, which lives only one year, is called an +_annual_ and is one of the easiest weeds to destroy. Mustard, plantain, +chess, dodder, cockle, crab grass, and Jimson weed are a few of our most +disagreeable annual weeds. + +The best time to kill any weed is when it is very small; therefore the +ground in early spring should be constantly stirred in order to kill the +young weeds before they grow to be strong and hardy. + +[Illustration: FIG. 57. WILD CARROT] + +The wild carrot differs from an annual in this way: it lives throughout +one whole year without producing seeds. During its first year it +accumulates a quantity of nourishment in the root, then rests in the +winter. Throughout the following summer it uses this nourishment rapidly +to produce its flowers and seeds. Then the plant dies. Plants that live +through two seasons in this way are called _biennials_. Weeds of this +kind may be destroyed by _cutting the roots below the leaves_ with a +grubbing-hoe or spud. A spud may be described as a chisel on a long +handle (see Fig. 58). If biennials are not cut low enough they will +branch out anew and make many seeds. Among the most common biennials are +the thistle, moth mullein, wild carrot, wild parsnip, and burdock. + +[Illustration: FIG. 58. A SPUD] + +[Illustration: FIG. 59. HOUND'S TONGUE] + +A third group of weeds consists of those that live for more than two +years. These weeds are usually most difficult to kill. They propagate by +means of running rootstocks as well as by seeds. Plants that live more +than two seasons are known as _perennials_ and include, for example, +many grasses, dock, Canada thistle, poison ivy, passion flower, horse +nettle, etc. There are many methods of destroying perennial weeds. They +may be dug entirely out and removed. Sometimes in small areas they may +be killed by crude sulphuric acid or may be starved by covering them +with boards or a straw stack or in some other convenient way. A method +that is very effective is to smother the weeds by a dense growth of +some other plant, for example, cowpeas or buckwheat. Cowpeas are to be +preferred, since they also enrich the soil by the nitrogen that the +root-tubercles gather. + +[Illustration: FIG. 60. CANADA THISTLE] + +Weeds do injury in numerous ways; they shade the crop, steal its +nourishment, and waste its moisture. Perhaps their only service is to +make lazy people till their crops. + + + =EXERCISE= + + You should learn to know by name the twenty worst weeds of your + vicinity and to recognize their seeds. If there are any weeds you + are not able to recognize, send a sample of each to your state + experiment station. Make a collection, properly labeled, of weeds + and weed seeds for your school. + + +SECTION XXI. SEED PURITY AND VITALITY + +Seeds produce plants. The difference between a large and a small yield +may depend upon the kind of plants we raise, and the kind of plant in +turn is dependent upon the seeds that we sow. + +Two things are important in the selection of seeds--purity and vitality. +Seeds should be _pure_; that is, when sown they should produce no other +plant than the one that we wish to raise. They should be able to grow. +The ability of a seed to grow is termed its _vitality_. Good seed should +be nearly or quite pure and should possess high vitality. The vitality +of seeds is expressed as a per cent; for example, if 97 seeds out of 100 +germinate, or sprout, the vitality is said to be 97. The older the seed +the less is its vitality, except in a few rare instances in which seeds +cannot germinate under two or three years. + +Cucumber seeds may show 90 per cent vitality when they are one year old, +75 per cent when two years old, and 70 per cent when three years +old--the per cent of vitality diminishing with increase of years. The +average length of life of the seeds of cultivated plants is short: for +example, the tomato lives four years; corn, two years; the onion, two +years; the radish, five years. The cucumber seed may retain life after +ten years; but the seeds of this plant too lose their vitality with an +increase in years. + +It is important when buying seeds to test them for purity and vitality. +Dealers who are not honest often sell old seeds, although they know that +seeds decrease in value with age. Sometimes, however, to cloak +dishonesty they mix some new seeds with the old, or bleach old and +yellow seeds in order to make them resemble fresh ones. + +It is important, therefore, that all seeds bought of dealers should be +thoroughly examined and tested; for if they do not grow, we not only pay +for that which is useless but we are also in great danger of producing +so few plants in our fields that we shall not get full use of the land, +and thus we may suffer a more serious loss than merely paying for a few +dead seeds. It will therefore be both interesting and profitable to +learn how to test the vitality of seeds. + +To test vitality plant one hundred seeds in a pot of earth or in damp +sand, or place them between moist pieces of flannel, and take care to +keep them moist and warm. Count those that germinate and thus determine +the percentage of vitality. Germinating between flannel is much quicker +than planting in earth. Care should be used to keep mice away from +germinating seeds. (See Fig. 61.) + +[Illustration: FIG. 61. A SEED-GERMINATOR +Consisting of two soup plates, some sand, and a piece of cloth] + +Sometimes the appearance of a package will show whether the seed has +been kept in stock a long time. It is, however, much more difficult to +find out whether the seeds are pure. You can of course easily +distinguish seeds that differ much from those you wish to plant, but +often certain weed seeds are so nearly like certain crop seeds as not to +be easily recognized by the eye. Thus the dodder or "love vine," which +so often ruins the clover crop, has seeds closely resembling clover +seeds. The chess, or cheat, has seeds so nearly like oats that only a +close observer can tell them apart. However, if you watch the seeds that +you buy, and study the appearance of crop seeds, you may become expert +in recognizing those that have no place in your planting. + +One case is reported in which a seed-dealer intentionally allowed an +impurity of 30 per cent to remain in the crop seeds, and this impurity +was mainly of weed seeds. There were 450,000 of one kind and 288,000 of +another in each pound of seed. Think of planting weeds at that rate! +Sometimes three fourths of the seeds you buy are weed seeds. + +In purchasing seeds the only safe plan is to buy of dealers whose +reputation can be relied upon. + +It not seldom happens that seeds, like corn, are stored in open cribs or +barns before the moisture is entirely dried out of the seeds. Such seeds +are liable to be frozen during a severe winter, and of course if this +happens they will not sprout the following spring. The only way to tell +whether such seeds have been killed is to test samples of them for +vitality. Testing is easy; replanting is costly and often results in a +short crop. + +[Illustration: FIG. 62. IMPURITIES IN SEEDS +Tube 1 represents one pound of redtop grass as bought; Tube 2, amount of +pure redtop grass seeds in Tube 1; Tube 3, amount of chaff and dirt in +Tube 1; Tube 4, amount of weed seeds in Tube 1; Tube 5, amount of total +waste in Tube 1; Tube 6, amount of pure germinable seeds in Tube 1] + + =EXERCISE= + + Examine seeds both for vitality and purity. Write for farmers' + bulletins on both these subjects. What would be the loss to a + farmer who planted a ten-acre clover field with seeds that were 80 + per cent bad? Can you recognize the seeds of the principal + cultivated plants? Germinate some beet seeds. What per cent comes + up? Can you explain? Collect for your school as many kinds of wild + and cultivated seeds as you can. + + + + +CHAPTER IV + +HOW TO RAISE A FRUIT TREE + + +Let each pupil grow an apple tree this year and attempt to make it the +best in his neighborhood. In your attempt suppose you try the following +plan. In the fall take the seed of an apple--a crab-apple is good--and +keep it in a cool place during the winter. The simplest way to do this +is to bury it in damp sand. In the spring plant it in a rich, loose +soil. + +Great care must be taken of the young shoot as soon as it appears above +the ground. You want to make it grow as tall and as straight as possible +during this first year of its life, hence you should give it rich soil +and protect it from animals. Before the ground freezes in the fall take +up the young tree with the soil that was around it and keep it all +winter in a cool, damp place. + +Now when spring comes it will not do to set out the carefully tended +tree, for an apple tree from seed will not be a tree like its parent, +but will tend to resemble a more distant ancestor. The distant ancestor +that the young apple tree is most likely to take after is the wild +apple, which is small, sour, and otherwise far inferior to the fruit we +wish to grow. It makes little difference, therefore, what kind of apple +seed we plant, since in any event we cannot be sure that the tree grown +from it will bear fruit worth having unless we force it to do so. + +[Illustration: FIG. 63. A YOUNG FRUIT-GROWER] + + +SECTION XXII. GRAFTING + +By a process known as _grafting_ you can force your tree to produce +whatever variety of apple you desire. Many people raise fruit trees +directly from seed without grafting. Thus they often produce really +worthless trees. By grafting they would make sure not only of having +good trees rather than poor ones but also of having the particular kind +of fruit that they wish. Hence you must now graft your tree. + +First you must decide what variety of apple you want to grow on the +tree. The Magnum Bonum is a great favorite as a fall apple. The Winesap +is a good winter apple, while the Red Astrachan is a profitable early +apple, especially in the lowland of the coast region. The Northern Spy, +AEsop, and Spitzenburg are also admirable kinds. Possibly some other +apple that you know may suit your taste and needs better than any of +these varieties. + +If you have decided to raise an AEsop or a Magnum Bonum or a Winesap, you +must now cut a twig from the tree of your choice and graft it upon the +little tree that you have raised. Choose a twig that is about the +thickness of the young tree at the point where you wish to graft. Be +careful to take the shoot from a vigorous, healthy part of the tree. + +[Illustration: FIG. 64. TONGUE GRAFTING] + +There are many ways in which you may join the chosen shoot or twig upon +the young tree, but perhaps the best one for you to use is known as +_tongue grafting_. This is illustrated in Fig. 64. The upper part, _b_, +which is the shoot or twig that you cut from the tree, is known as the +_scion_; the lower part, _a_, which is the original tree, is called the +_stock_. + +Cut the scion and stock as shown in Fig. 64. Join the cut end of the +scion to the cut end of the stock. When you join them, notice that under +the bark of each there is a thin layer of soft, juicy tissue. This is +called the _cambium_. To make a successful graft the cambium in the +scion must exactly join the cambium in the stock. Be careful, then, to +see that cambium meets cambium. You now see why grafting can be more +successfully done if you select a scion and stock of nearly the same +size. + +[Illustration: FIG. 65. A COMPLETED GRAFT +Showing scion and stock from which it was made] + +After fitting the parts closely together, bind them with cotton yarn +(see Fig. 65) that has been coated with grafting wax. This wax is made +of equal parts of tallow, beeswax, and linseed oil. Smear the wax +thoroughly over the whole joint, and make sure that the joint is +completely air-tight. + +[Illustration: FIG. 66. +To make a root graft, cut along the slanting line] + +The best time to make this graft is when scion and stock are dormant, +that is, when they are not in leaf. During the winter, say in February, +is the best time to graft the tree. Set the grafted tree away again in +damp sand until spring, then plant it in loose, rich soil. + +Since all parts growing above the graft will be of the same kind as the +scion, while all branches below it will be like the stock, it is well to +graft low on the stock or even upon the root itself. The slanting double +line in Fig. 66 shows the proper place to cut off for such grafting. + +[Illustration: FIG. 67. A COMPLETED ROOT GRAFT] + +If you like you may sometime make the interesting and valuable +experiment of grafting scions from various kinds of apple trees on the +branches of one stock. In this way you can secure a tree bearing a +number of kinds of fruit. You may thus raise the Bonum, Red Astrachan, +Winesap, and as many other varieties of apples as you wish, upon one +tree. For this experiment, however, you will find it better to resort to +_cleft grafting_, which is illustrated in Fig. 68. + +[Illustration: FIG. 68. CLEFT GRAFTING] + +Luther Burbank, the originator of the Burbank potato, in attempting to +find a variety of apple suited to the climate of California, grafted +more than five hundred kinds of apple scions on one tree, so that he +might watch them side by side and find out which kind was best suited to +that state. + + +SECTION XXIII. BUDDING + +If, instead of an apple tree, you were raising a plum or a peach tree, a +form of propagation known as _budding_ would be better than grafting. +Occasionally budding is also employed for apples, pears, cherries, +oranges, and lemons. Budding is done in the following manner. A single +bud is cut from the scion and is then inserted under the bark of a +one-year-old peach seedling, so that the cambium of the bud and stock +may grow together. + +[Illustration: FIG. 69. HOW TO CUT A BUD FROM A SCION] + +[Illustration: FIG. 70. THE STEPS IN BUDDING] + +Cut scions of the kind of fruit tree you desire from a one-year-old twig +of the same variety. Wrap them in a clean, moist cloth until you are +ready to use them. Just before using cut the bud from the scion, as +shown in Fig. 69. This bud is now ready to be inserted on the north side +of the stock, just two or three inches above the ground. The north side +is selected to avoid the sun. Now, as shown at _a_ in Fig. 70, make a +cross and an up-and-down incision, or cut, on the stock; pull the bark +back carefully, as shown in _B_; insert the bud _C_, as shown in _D_; +then fold the bark back and wrap with yarn or raffia, as shown in _E_. +As soon as the bud and branches have united, remove the wrapping to +prevent its cutting the bark and cut the tree back close to the bud, as +in Fig. 71, so as to force nourishment into the inserted bud. + +[Illustration: FIG. 71. +Sloping line shows where to cut tree] + +Budding is done in the field without disturbing the tree as it stands in +the ground. The best time to do budding is during the summer or fall +months, when the bark is loose enough to allow the buds to be easily +inserted. + +Trees may be budded or grafted on one another only when they are nearly +related. Thus the apple, crab-apple, hawthorn, and quince are all +related closely enough to graft or bud on one another; the pear grows on +some hawthorns, but not well on an apple; some chestnuts will unite with +some kinds of oaks. + +[Illustration: FIG. 72. +Lines show where to trim] + +By using any of these methods you can succeed in getting with certainty +the kind of tree that you desire. + +[Illustration: BOTH BUSY STORING APPLES] + + +SECTION XXIV. PLANTING AND PRUNING + +The apple tree that you grafted should be set out in the spring. Dig a +hole three or four feet in diameter where you wish the tree to grow. +Place the tree in the hole and be very careful to preserve all the fine +roots. Spread the roots out fully, water them, and pack fine, rich soil +firmly about them. Place stakes about the young tree to protect it from +injury. If the spot selected is in a windy location, incline the tree +slightly toward the prevailing wind. + +[Illustration: FIG. 73. +Present shape comes from pruning] + +[Illustration: FIG. 74. +Correct shape] + +You must prune the tree as it grows. The object of pruning is to give +the tree proper shape and to promote fruit-bearing. If the bud at the +end of the main shoot grows, you will have a tall, cone-shaped tree. If, +however, the end of the young tree be cut or "headed back" to the lines +shown in Fig. 72, the buds below this point will be forced to grow and +make a tree like that shown in Fig. 73. The proper height of heading for +different fruits varies. For the apple tree a height of two or three +feet is best. + +Cutting an end bud of a shoot or branch always sends the nourishment and +growth into the side buds. Trimming or pinching off the side buds throws +the growth into the end bud. You can therefore cause your tree to take +almost any shape you desire. The difference between the trees shown in +Figs. 73 and 74 is entirely the result of pruning. Fig. 74 illustrates +in general a correctly shaped tree. It is evenly balanced, admits light +freely, and yet has enough foliage to prevent sun-scald. Figs. 75 and 76 +show the effect of wisely thinning the branches. + +[Illustration: FIG. 75. +Unthinned] + +[Illustration: FIG. 76. +Properly thinned] + +The best time to prune is either in the winter or before the buds start +in the spring. Winter pruning tends to favor wood-production, while +summer pruning lessens wood-production and induces fruitage. + +Each particular kind of fruit requires special pruning; for example, the +peach should be made to assume the shape illustrated in Fig. 77. This is +done by successive trimmings, following the plan illustrated in Figs. +71, 78, 79. You will gain several advantages from these trimmings. +First, nourishment will be forced into the peach bud that you set on +your stock. This will secure a vigorous growth of the scion. By a second +trimming take off the "heel" (Fig. 78, _h_) close to the tree, and thus +prevent decay at this point. One year after budding you should reduce +the tree to a "whip," as in Fig. 79, by trimming at the dotted line in +Fig. 78. This establishes the "head" of the tree, which in the case of +the peach should be very low,--about sixteen inches from the ground,--in +order that a low foliage may lessen the danger of sun-scald to the main +trunk. + +[Illustration: FIG. 77. THE CUSTOMARY WAY OF PRUNING A PEACH] + +[Illustration: FIG. 78. TWO-YEAR-OLD TREE +Cut off heel, _h_] + + +In pruning never leave a stump such as is shown in Fig. 78, _h_. Such a +stump, having no source of nourishment, will heal very slowly and with +great danger of decay. If this heel is cleanly cut on the line _ch_ +(Fig. 78), the wound will heal rapidly and with little danger of decay. +Leaving such a stump endangers the soundness of the whole tree. Fig. 80 +shows the results of good and poor pruning on a large tree. When large +limbs are removed it is best to paint the cut surface. The paint will +ward off fungous disease and thus keep the tree from rotting where it +was cut. + +Pruning that leaves large limbs branching, as in Fig. 74, _a_, is not to +be recommended, since the limbs when loaded with fruit or when beaten by +heavy winds are liable to break. Decay is apt to set in at the point of +breakage. The entrance of decay-fungi through some such wound or through +a tiny crevice at such a crotch is the beginning of the end of many a +fruitful tree. + +[Illustration: FIG. 79. THREE-YEAR-OLD TREE CUT BACK] + +Sometimes a tree will go too much to wood and too little to fruit. This +often happens in rich soil and may be remedied by another kind of +pruning known as _root-pruning_. This consists in cutting off a few of +the roots in order to limit the food supply of the plant. You ought to +learn more about root-pruning, however, before you attempt it. + +[Illustration: FIG. 80. +Refuses to Heal--Heals promptly] + +How is a peach tree made? First, the blossom appears. Then pollination +and fertilization occur. The fruit ripens. The pit, or seed, is saved. +In the spring of the next year the seed is planted. The young tree, +known as the stock, comes up quickly. In August of that year a bud of +the variety which is wanted is inserted in the little stock, near the +ground. One year later, in the spring, the stock is cut off just above +the bud. The bud throws out a shoot, which grows to a height of about +six feet, and in the fall this little peach tree is sold as a +one-year-old tree. However, as is seen, the root is two years old. + +[Illustration: FIG. 81. READY TO BEAR] + +How is an apple tree made? The seeds are saved in the fall of one year +and planted the following year. The seedlings of the apple do not grow +so rapidly as those of the peach. At the end of the year they are taken +up and sorted, and in the following spring they are planted. In July or +August they are budded. In the spring of the next year the stock is cut +off above the bud, and the bud-shoot grows three or four feet. One year +later the shoot branches and the top begins to form; and in the fall of +the following year the tree may be sold as a two-year-old, although most +persons prefer to buy it a year later as a three-year-old. In some parts +of the country, particularly in the West, the little seedling is grafted +in the second winter, in a grafting room, and the young grafts are set +in the nursery row in the spring to complete their growth. + +The planting in the orchard of the young peach and the young apple tree +is done in practically the same way. After the hole for the tree has +been dug and after proper soil has been provided, the roots should be +spread and the soil carefully packed around them. + + + =EXERCISE= + + Do you know any trees in your neighborhood that bear both wild and + budded or grafted fruit? What are the chief varieties of apples + grown in your neighborhood? grapes? currants? plums? cherries? + figs? What is a good apple tree worth? Is there any land near by + that could support a tree and is not now doing so? Examine several + orchards and see whether the trees have the proper shape. Do you + see any evidence of poor pruning? Do you find any heels? Can you + see any place where heels have resulted in rotten or hollow trees? + How could you have prevented this? Has the removal of branches ever + resulted in serious decay? How is this to be prevented? + + If your home is not well stocked with all the principal kinds of + fruit, do you not want to propagate and attend to some of each + kind? You will be surprised to find how quickly trees will bear and + how soon you will be eating fruit from your own planting. Growing + your own trees will make you feel proud of your skill. + + + + +CHAPTER V + +HORTICULTURE + + +SECTION XXV. MARKET-GARDENING + +The word _horticulture_ is one of those broad words under which much is +grouped. It includes the cultivation of orchard fruits, such as apples +and plums; of small fruits, such as strawberries and raspberries; of +garden vegetables for the table; of flowers of all sorts, including +shrubbery and ornamental trees and their arrangement into beautiful +landscape effects around our homes. Horticulture then is a name for an +art that is both far-reaching and important. + +The word _gardening_ is generally given to that part of horticulture +which has for its chief aim the raising of vegetables for our tables. + +Flower-gardening, or the cultivation of plants valued for their bloom in +making ornamental beds and borders and furnishing flowers for the +decoration of the home, is generally called _floriculture_. +Landscape-gardening is the art of so arranging flower-beds, grass, +shrubbery, and trees as to produce pleasing effects in the grounds +surrounding our homes and in great public parks and pleasure grounds. + +Landscape-gardening, like architecture, has developed intoll as the +artist makes them on canvas, but uses natural objects in his pictures +instead of paint and canvas. + +=Market-Gardening.= Formerly market-gardening was done on small tracts +of land in the immediate vicinity of large cities, where supplies of +stable manure could be used from the city stables. But with the great +increase in the population of the cities, these small areas could no +longer supply the demand, and the introduction of commercial fertilizers +and the building of railroads enabled gardeners at great distances from +city markets to grow and ship their products. Hence the markets, even in +winter, are now supplied with fresh vegetables from regions where there +is no frost. Then, as spring opens, fruits and vegetables are shipped +from more temperate regions. Later vegetables and fruits come from the +sections nearer the great cities. This gradual nearing of the supply +fields continues until the gardens near the cities can furnish what is +needed. + +[Illustration: FIG. 82. STRAWBERRY-GROWING IS AN ART] + +The market-gardeners around the great Northern cities, finding that +winter products were coming from the South and from warmer regions, +began to build hothouses and by means of steam and hot-water pipes to +make warm climates in these glass houses. Many acres of land in the +colder sections of the country are covered with heated glass houses, and +in them during the winter are produced fine crops of tomatoes, lettuce, +radishes, cauliflowers, eggplants, and other vegetables. The degree of +perfection which these attain in spite of having such artificial +culture, and their freshness as compared to the products brought from a +great distance, have made winter gardening under glass a very profitable +business. But it is a business that calls for the highest skill and the +closest attention. + +[Illustration: FIG. 83. SETTING PLANTS IN A COLD-FRAME] + +No garden, even for home use, is complete without some glass sashes, and +the garden will be all the more successful if there is a small heated +greenhouse for starting plants that are afterwards to be set in the +garden. + +=Hotbeds.= If there is no greenhouse, a hotbed is an important help in +the garden. The bed is made by digging a pit two feet deep, seven feet +wide, and as long as necessary. + +The material for the hotbed is fresh horse manure mixed with leaves. +This is thrown into a heap to heat. As soon as steam is seen coming from +the heap the manure is turned over and piled again so that the outer +part is thrown inside. When the whole is uniformly heated and has been +turned two or three times, it is packed firmly into the pit already dug. + +A frame six feet wide, twelve inches high on the north side and eight +inches on the south side and as long as the bed is to be, is now made of +plank. This is set upon the heated manure, thus leaving six inches on +each side outside the frame. More manure is then banked all around it, +and three or four inches of fine light and rich soil are placed inside +the frame. + +[Illustration: FIG. 84. THE GLADIOLUS] + +The frame is then covered with hotbed sashes six feet long and three +feet wide. These slide up and down on strips of wood let into the sides +of the frame. A thermometer is stuck into the soil and closely watched, +for there will be too much heat at first for sowing seed. When the heat +in the early morning is about 85 deg., seeds may be sowed. The hotbed is +used for starting tomato plants, eggplants, cabbage plants, and other +vegetables that cannot stand exposure. It should be made about eight or +ten weeks before the tender plants can be set out in the locality. In +the South and Southwest it should be started earlier than in the North. +For growing the best tomato plants, and for such hardy plants as lettuce +and cabbage, it will be better to have cold-frames in addition to the +hotbed; these need not be more than two or three sashes. + +=Cold-Frames.= A cold-frame is like the frame used for a hotbed, but it +is placed on well-manured soil in a sheltered spot. It is covered with +the same kind of sashes and is used for hardening the plants sowed in +the hotbed. The frame must be well banked with earth on the outside, and +the glass must be covered on cold nights with straw, mats, or old +carpets to keep out frost. + +[Illustration: FIG. 85. FRAME TO CARRY THE SASH OF A HOTBED OR COLD-FRAME] + +=Care of Hotbed and Cold-Frame.= If the sun be allowed to shine brightly +on the glass of a cold-frame or hotbed, it will soon raise the +temperature in the hotbed to a point that will destroy the plants. It is +necessary, then, to pay close attention to the bed and, when the sun +shines, to slip the sashes down or raise them and place a block under +the upper end to allow the steam to pass off. The cold-frame also must +be aired when the sun shines, and the sashes must be gradually slipped +down in mild weather. Finally, they may be removed entirely on sunshiny +days, so as to accustom the plants to the open air, but they must be +replaced at night. For a while before setting the plants in the open +gardens, leave the sashes off night and day. + +[Illustration: FIG. 86. GREENHOUSE AND COLD-FRAMES] + +While the hotbed may be used for starting plants, it is much better and +more convenient to have a little greenhouse with fire heat for this +purpose. A little house with but four sashes on each side will be enough +to start a great many plants, and will also give room for some flowers +in pots. With such a house a student can learn to manage a more +extensive structure if he gives close attention to airing, watering, and +keeping out insects. + +=Sowing.= The time for sowing the different kinds of seeds is an +important matter. Seeds vary greatly in their requirements. All need +three conditions--a proper degree of heat, moisture, and air. Some +seeds, like English peas, parsnips, beets, and radishes, will germinate +and grow when the soil is still cool in the early spring, and peas will +stand quite a frost after they are up. Therefore we plant English peas +as early as the ground can be worked. + +But if we should plant seeds like corn, string (or snap) beans, +squashes, and other tender plants before the ground is warm enough, they +would decay. + +Seeds cannot germinate in soil that is perfectly dry, for there must be +moisture to swell them and to start growth. The oxygen of the air is +also necessary, and if seeds are buried so deeply that the air cannot +reach them, they will not grow, even if they are warm and moist. + +[Illustration: FIG. 87. GATHERING AND SHIPPING CELERY] + +The depth of planting must vary with the character and size of the seed. +English peas may be covered six inches deep and will be all the better +for such covering, but if corn be covered so deep, it hardly gets above +the ground. In planting small seeds like those of the radish, cabbage, +turnip, lettuce, etc., a good rule is to cover them three times the +thickness of the seed. + +In sowing seeds when the ground is rather dry, it is a good plan, after +covering them, to tramp on the row so as to press the soil closely to +the seeds and to help it to retain moisture for germination, but do not +pack the soil if it is damp. + +In spring never dig or plow the garden while it is still wet, but always +wait until the soil is dry enough to crumble freely. + +=What Crops to grow.= The crops to be raised will of course depend upon +each gardener's climate, surroundings, and markets. Sometimes it may pay +a grower, if his soil and climate are particularly suited to one crop, +to expend most of his time and energy on this crop; for example, in some +sections of New York, on potatoes; in parts of Michigan, on celery; in +Georgia, on watermelons; in western North Carolina, on cabbage. If +circumstances allow this sort of gardening, it has many advantages, for +of course it is much easier to acquire skill in growing one crop than in +growing many. + +[Illustration: FIG. 88. A LARGE YIELD OF CABBAGES] + +On the other hand, it often happens that a gardener's situation requires +him to grow most of the crops known to gardening. Each gardener then +must be guided in his selection of crops by his surroundings. + +=Care of Crops.= The gardener who wishes to attain the greatest success +in his art must do four things: + +First, he must make his land rich and keep it rich. Much of his success +depends on getting his crops on the market ahead of other growers. To do +this, his crops must grow rapidly, and crops grow rapidly only in rich +soil. Then, too, land conveniently situated for market-gardening is +nearly always costly. Hence the successful market-gardener must plan to +secure the largest possible yield from as small an area as is +practicable. The largest yield can of course be secured from the richest +land. + +Second, the gardener must cultivate his rich land most carefully and +economically. He crowds his land with products that must grow apace. +Therefore he, least of all growers, can afford to have any of his soil +go to feed weeds, to have his land wash, or to have his growing crops +suffer for lack of timely and wise cultivation. To cultivate his land +economically the gardener must use the best tools and machines and the +best methods of soil management. + +Third, to get the best results he must grow perfect vegetables. To do +this, he must add to good tillage a knowledge of the common plant +diseases and of the ways of insects and bacterial pests; he must know +how and when to spray, how and when to treat his seed, how and when to +poison, how and when to trap his insect foes and to destroy their +hiding-places. + +Fourth, not only must the gardener grow perfect vegetables, but he must +put them on the market in perfect condition and in attractive shape. Who +cares to buy wilted, bruised, spoiling vegetables? Gathering, bundling, +crating, and shipping are all to be watched carefully. Baskets should be +neat and attractive, crates clean and snug, barrels well packed and well +headed. Careful attention to all these details brings a rich return. + +Among the gardener's important crops are the following: + +=Asparagus.= This is a hardy plant. Its seed may be sowed either early +in the spring or late in the fall. The seeds should be planted in rows. +If the plants are well cultivated during the spring and summer, they +will make vigorous roots for transplanting in the autumn. + +In the fall prepare a piece of land by breaking it unusually deep and by +manuring it heavily. After the land is thoroughly prepared, make in it +furrows for the asparagus roots. These furrows should be six inches deep +and three feet apart. Then remove the roots from the rows in which they +have been growing during the summer, and set them two feet apart in the +prepared furrows. Cover carefully at once. + +[Illustration: FIG. 89. A CRATE OF ASPARAGUS] + +In the following spring the young shoots must be well cultivated. In +order to economize space, beets or lettuce may be grown between the +asparagus rows during this first season. With the coming of cold weather +the asparagus must again be freely manured and all dead tops cut off. +Some plants will be ready for market the second spring. If the bed is +kept free from weeds and well manured, it will increase in +productiveness from year to year. + +=Beans.= The most generally planted beans are those known as string, or +snap, beans. Of the many varieties, all are sensitive to cold and hence +must not be planted until frost is over. + +Another widely grown kind of bean is the lima, or butter, bean. There +are two varieties of the lima bean. One is large and generally grows on +poles. This kind does best in the Northern states. The other is a small +bean and may be grown without poles. This kind is best suited to the +warmer climates of the Southern states. + +=Cabbage.= In comparatively warm climates the first crop of cabbage is +generally grown in the following way. The seeds are sowed in beds in +September, and the plants grown from this sowing are in November +transplanted to ground laid off in sharp ridges. The young plants are +set on the south side of the ridges in order that they may be somewhat +protected from the cold of winter. As spring comes on, the ridge is +partly cut down at each working until the field is leveled, and +thereafter the cultivation should be level. + +[Illustration: FIG. 90. CABBAGE READY FOR SHIPMENT] + +Early cabbages need heavy applications of manure. In the spring, nitrate +of soda applied in the rows is very helpful. + +Seeds for the crop following this early crop should be sowed in March. +Of course these seeds should be of a later variety than the first used. +The young plants should be transplanted as soon as they are large +enough. Early cabbages are set in rows three feet apart, the plants +eighteen inches apart in the row. As the later varieties grow larger +than the earlier ones, the plants should be set two feet apart in the +row. + +In growing late fall and winter cabbage the time of sowing varies with +the climate. For the Northern and middle states, seeding should be done +during the last of March and in April. South of a line passing west from +Virginia it is hard to carry cabbages through the heat of summer and get +them to head in the fall. However, if the seeds are sowed about the +first of August in rich and moist soil and the plants set in the same +sort of soil in September, large heads can be secured for the December +market. + +[Illustration: FIG. 91. CELERY TRIMMED, WASHED, AND BUNCHED] + +=Celery.= In the extreme northern part of our country, celery seeds are +often sowed in a greenhouse or hotbed. This is done in order to secure +plants early enough for summer blanching. This plan, however, suits only +very cool climates. + +In the middle states the seeds are usually sowed in a well-prepared bed +about April. The young plants are moved to other beds as soon as they +need room. Generally they are transplanted in July to rows prepared for +them. These should be four feet apart, and the plants should be set six +inches apart in the row. The celery bed should be carefully cultivated +during the summer. In the fall, hill the stalks up enough to keep them +erect. After the growing season is over dig them and set them in +trenches. The trenches should be as deep as the celery is tall, and +after the celery is put in them they should be covered with boards and +straw. + +In the more southern states, celery is usually grown in beds. The beds +are generally made six feet wide, and rows a foot apart are run +crosswise. The plants are set six inches apart, in September, and the +whole bed is earthed up as the season advances. Finally, when winter +comes the beds are covered with leaves or straw to prevent the plants +from freezing. The celery is dug and bunched for market at any time +during the winter. + +By means of cold-frames a profitable crop of spring celery may be +raised. Have the plants ready to go into the cold-frames late in October +or early in November. The soil in the frame should be made very deep. +The plants should make only a moderately rapid growth during the winter. +In the early spring they will grow rapidly and so crowd one another as +to blanch well. As celery grown in this way comes on the market at a +time when no other celery can be had, it commands a good price. + +In climates as warm as that of Florida, beds of celery can be raised in +this way without the protection of cold-frames. A slight freeze does not +hurt celery, but a long-continued freezing spell will destroy it. + +Some kinds of celery seem to turn white naturally. These are called +self-blanching kinds. Other kinds need to be banked with earth in order +to make the stalks whiten. This kind usually gives the best and crispest +stalks. + +=Cucumbers and Cantaloupes.= Although cucumbers and cantaloupes are very +different plants, they are grown in precisely the same way. Some +gardeners plant them in hills. However, this is perhaps not the best +plan. It is better to lay the land off in furrows six feet apart. After +filling these with well-rotted stable manure, throw soil over them. Then +make the top flat and plant the seeds. After the plants are up thin them +out, leaving them a foot or more apart in the rows. Cultivate regularly +and carefully until the vines cover the entire ground. + +It is a good plan to sow cowpeas at the last working of cantaloupes, in +order to furnish some shade for the melons. As both cucumbers and +cantaloupes are easily hurt by cold, they should not be planted until +the soil is warm and all danger of frost is past. + +Cucumbers are always cut while they are green. They should never be +pulled from the vine, but should always be cut with a piece of the stem +attached. Cantaloupes should be gathered before they turn yellow and +should be ripened in the house. + +[Illustration: FIG. 92. STRIPED CUCUMBER BEETLE AND LARVA +All magnified] + +In some sections of the country the little striped cucumber-beetle +attacks the melons and cucumbers as soon as they come up. These beetles +are very active, and if their attacks are not prevented they will +destroy the tender plants. Bone dust and tobacco dust applied just as +the plants appear above the ground will prevent these attacks. This +treatment not only keeps off the beetle, but also helps the growth of +the plants. + +=Eggplants.= Eggplants are so tender that they cannot be transplanted +like tomatoes to cold-frames and gradually hardened to stand the cold +spring air. These plants, started in a warm place, must be kept there +until the soil to which they are to be transplanted is well warmed by +the advance of spring. After the warm weather has fully set in, +transplant them to rich soil, setting them three feet apart each way. +This plant needs much manure. If large, perfect fruit is expected, the +ground can hardly be made too rich. + +Eggplants are subject to the same bacterial blight that is so +destructive to tomatoes. The only way to prevent this disease is to +plant in ground not lately used for tomatoes or potatoes. + +[Illustration: FIG. 93. AN ONION HARVEST] + +=Onions.= The method of growing onions varies with the use to which it +is intended to put them. To make the early sorts, which are eaten green +in the spring, little onions called _sets_ are planted. These are grown +from seeds sowed late in the spring. The seeds are sowed thickly in rows +in rather poor land. The object of selecting poor land is that the +growth of the sets may be slow. When the sets have reached the size of +small marbles, they are ready for the fall planting. + +In the South the sets may be planted in September. Plant them in rows in +rich and well-fertilized soil. They will be ready for market in March +or April. In the more northerly states the sets are to be planted as +early as possible in the spring. + +To grow ripe onions the seeds must be sowed as early in the spring as +the ground can be worked. The plants are thinned to a stand of three +inches in the rows. As they grow, the soil is drawn away from them so +that the onions sit on top of the soil with only their roots in the +earth. + +[Illustration: FIG. 94. HOTBED FOR STARTING TOMATO PLANTS] + +As soon as the tops ripen pull the onions and let them lie in the sun +until the tops are dry. Then put them under shelter. As onions keep best +with their tops attached, do not remove these until it is time for +marketing. + +=Peas.= The English pea is about the first vegetable of the season to be +planted. It may be planted as soon as the ground is in workable +condition. Peas are planted in rows, and it is a good plan to stretch +wire netting for them to climb on. However, where peas are extensively +cultivated they are allowed to fall on the ground. + +There are many sorts of peas, differing both in quality and in time of +production. The first to be planted are the extra-early varieties. These +are not so fine as the later, wrinkled sorts, but the seeds are less apt +to rot in cold ground. Following these, some of the fine, wrinkled sorts +are to be planted in regular succession. Peas do not need much manure +and do best in a light, warm soil. + +=Tomatoes.= There is no vegetable grown that is more widely used than +the tomato. Whether fresh or canned it is a staple article of food that +can be served in many ways. + +By careful selection and breeding, the fruit of the tomato has in recent +years been much improved. There are now many varieties that produce +perfectly smooth and solid fruit, and the grower can hardly go amiss in +his selection of seeds if he bears his climate and his particular needs +in mind. + +Early tomatoes are started in the greenhouse or in the hotbed about ten +weeks before the time for setting the plants in the open ground. They +are transplanted to cold-frames as soon as they are large enough to +handle. This is done to harden the plants and to give them room to grow +strong before the final transplanting. + +In kitchen gardens tomatoes are planted in rows four feet apart with the +plants two feet apart in the rows. They are generally trained to stakes +with but one stalk to a stake. When there is plenty of space, however, +the plants are allowed to grow at will and to tumble on the ground. In +this way they bear large crops. During the winter the markets are +supplied with tomatoes either from tropical sections or from hothouses. +As those grown in the hothouses are superior in flavor to those shipped +from Florida and from the West Indies, and as they command good prices, +great quantities are grown in this way. + +In the South the bacterial blight which attacks the plants of this +family is a serious drawback to tomato culture. The only way to escape +this disease is to avoid planting tomatoes on land in which eggplants, +tomatoes, or potatoes have been blighted. Lime spread around the plants +seems to prevent the blight for one season on some soils. + +At the approach of frost in the fall, green tomatoes can easily be +preserved by wrapping them in paper. Gather them carefully and wrap each +separately. Pack them in boxes and store in a cellar that is close +enough to prevent the freezing of the fruit. A few days before the +tomatoes are wanted for the table unpack as many as are needed, remove +the paper, and allow them to ripen in a warm room. + +Tomatoes require a rich soil. Scattering a small quantity of nitrate of +soda around their roots promotes rapid growth. + +=Watermelons.= As watermelons need more room than can usually be spared +in a garden, they are commonly grown as a field crop. + +A very light, sandy soil suits watermelons best. They can be grown on +very poor soil if a good supply of compost be placed in each hill. The +land for the melons should be laid off in about ten-foot checks; that +is, the furrows should cross one another at right angles about every ten +feet. A wide hole should be dug where the furrows cross, and into this +composted manure should be put. + +The best manure for watermelons is a compost of stable manure and +wood-mold from the forest. Pile the manure and wood-mold in alternate +layers for some time before the planting season. During the winter cut +through the pile several times until the two are thoroughly mixed and +finely pulverized. Be sure to keep the compost heap under shelter. +Compost will lose in value if it is exposed to rains. + +At planting-time, put two or three shovelfuls of this compost into each +of the prepared holes, and over the top of the manure scatter a handful +of any high-grade complete fertilizer. Then cover fertilizer and manure +with soil, and plant the seeds in this soil. In cultivating, plow both +ways of the checked rows and throw the earth toward the plants. + +Some growers pinch off the vines when they have grown about three feet +long. This is done to make them branch more freely, but the pinching is +not necessary. + +A serious disease, the watermelon wilt, is rapidly spreading through +melon-growing sections. This disease is caused by germs in the soil, and +the germs are hard to kill. If the wilt should appear in your +neighborhood, do not allow any stable manure to be used on your melon +land, for the germs are easily scattered by means of stable manure. The +germs also cling to the seeds of diseased melons, and these seeds bear +the disease to other fields. If you treat melon seeds as you are +directed on page 135 to treat oat seeds, the germs on the seeds will be +destroyed. By crossing the watermelon on the citron melon, a watermelon +that is resistant to wilt has recently been developed and successfully +grown in soils in which wilt is present. The new melon, inferior in +flavor at first, is being improved from season to season and bids fair +to rival other melons in flavor. + +[Illustration: FIG. 95. DEWBERRIES] + + +SECTION XXVI. FLOWER GARDENING + +The comforts and joys of life depend largely upon small things. Of these +small things perhaps none holds a position of greater importance in +country life than the adornment of the home, indoors and outdoors, with +flowers tastefully arranged. Their selection and planting furnish +pleasant recreation; their care is a pleasing employment; and each +little plant, as it sprouts and grows and develops, may become as much a +pet as creatures of the sister animal kingdom. A beautiful, well-kept +yard adds greatly to the pleasure and attractiveness of a country home. +If a beautiful yard and home give joy to the mere passer-by, how much +more must their beauty appeal to the owners. The decorating of the home +shows ambition, pride, and energy--important elements in a successful +life. + +[Illustration: FIG. 96. AN EASY WAY TO BEAUTIFY THE HOME] + +Plant trees and shrubs in your yard and border your masses of shrubbery +with flower-beds. Do not disfigure a lawn by placing a bed of flowers in +it. Use the flowers rather to decorate the shrubbery, and for borders +along walks, and in the corners near steps, or against foundations. + +If you wish to raise flowers for the sake of flowers, not as +decorations, make the flower-beds in the back yard or at the side of the +house. + +[Illustration: FIG. 97. A BACK YARD TO REFINE THE CHILDREN OF THE +FAMILY] + +Plants may be grown from seeds or from bulbs or from cuttings. The +rooting of cuttings is an interesting task to all who are fond of +flowers. Those who have no greenhouse and who wish to root cuttings of +geraniums, roses, and other plants may do so in the following way. Take +a shallow pan, an old-fashioned milk pan for instance, fill it nearly +full of clean sand, and then wet the sand thoroughly. Stick the cuttings +thickly into this wet sand, set the pan in a warm, sunny window, and +keep the sand in the same water-soaked condition. Most cuttings will +root well in a few weeks and may then be set into small flower-pots. +Cuttings of tea roses should have two or three joints and be taken from +a stem that has just made a flower. Allow one of the rose leaves to +remain at the top of the cutting. Stick this cutting into the sand and +it will root in about four weeks. Cuttings of Cape jasmine may be rooted +in the same way. Some geraniums, the rose geranium for example, may be +grown from cuttings of the roots. + +[Illustration: FIG. 98. REPOTTING] + +Bulbs are simply the lower ends of the leaves of a plant wrapped tightly +around one another and inclosing the bud that makes the future +flower-stalk. The hyacinth, the narcissus, and the common garden onion +are examples of bulbous plants. The flat part at the bottom of the bulb +is the stem of the plant reduced to a flat disk, and between each two +adjacent leaves on this flat stem there is a bud, just as above-ground +there is a bud at the base of a leaf. These buds on the stem of the bulb +rarely grow, however, unless forced to do so artificially. The number +of bulbs may be greatly increased by making these buds grow and form +other bulbs. In increasing hyacinths the matured bulbs are dug in the +spring, and the under part of the flat stem is carefully scraped away to +expose the base of the buds. The bulbs are then put in heaps and covered +with sand. In a few weeks each bud has formed a little bulb. The +gardener plants the whole together to grow one season, after which the +little bulbs are separated and grown into full-sized bulbs for sale. +Other bulbs, like the narcissus or the daffodil, form new bulbs that +separate without being scraped. + +[Illustration: FIG. 99. A CLEMATIS] + +There are some other plants which have underground parts that are +commonly called bulbs but which are not bulbs at all; for example, the +gladiolus and the caladium, or elephant's ear. Their underground parts +are bulblike in shape, but are really solid flattened stems with eyes +like the underground stem of the Irish potato. These parts are called +_corms_. They may be cut into pieces like the potato and each part will +grow. + +The dahlia makes a mass of roots that look greatly like sweet potatoes, +but there are no eyes on them as there are on the sweet potato. The only +eyes are on the base of the stem to which they are joined. They may be +sprouted like sweet potatoes and then soft cuttings made of the green +shoots, after which they may be rooted in the greenhouse and later +planted in pots. + +There are many perennial plants that will bloom the first season when +grown from the seed, though such seedlings are seldom so good as the +plants from which they came. They are generally used to originate new +varieties. Seeds of the dahlia, for instance, can be sowed in a box in a +warm room in early March, potted as soon as the plants are large enough +to handle, and finally planted in the garden when the weather is warm. +They will bloom nearly as soon as plants grown by dividing the roots or +from cuttings. + +[Illustration: FIG. 100. OUTDOOR-GROWN CHRYSANTHEMUMS] + +In growing annual plants from seed, there is little difficulty if the +grower has a greenhouse or a hotbed with a glass sash. Even without +these the plants may be grown in shallow boxes in a warm room. The best +boxes are about four inches deep with bottoms made of slats nailed a +quarter of an inch apart to give proper drainage. Some moss is laid over +the bottom to prevent the soil from sifting through. The boxes should +then be filled with light, rich soil. Fine black forest mold, thoroughly +mixed with one fourth its bulk of well-rotted manure, makes the best +soil for filling the seed-boxes. If this soil be placed in an oven and +heated very hot, the heat will destroy many weeds that would otherwise +give trouble. After the soil is put in the boxes it should be well +packed by pressing it with a flat wooden block. Sow the seeds in +straight rows, and at the ends of the rows put little wooden labels with +the names of the flowers on them. + +[Illustration: FIG. 101. THE CARNATION (ELDORADO)] + +Seeds sowed in the same box should be of the same general size in order +that they may be properly covered, for seeds need to be covered +according to their size. After sowing the seed, sift the fine soil over +the surface of the box. The best soil for covering small seeds is made +by rubbing dry moss and leaf-mold through a sieve together. This makes a +light cover that will not bake and will retain moisture. After covering +the seeds, press the soil firm and smooth with a wooden block. Now +sprinkle the covering soil lightly with a watering-pot until it is +fairly moistened. Lay some panes of glass over the box to retain the +moisture, and avoid further watering until moisture becomes absolutely +necessary. Too much watering makes the soil too compact and rots the +seed. + +As soon as the seedlings have made a second pair of leaves, take them up +with the point of a knife and transplant them into other boxes filled in +the same way. They should be set two inches apart so as to give them +room to grow strong. They may be transplanted from the boxes to the +flower-garden by taking an old knife-blade and cutting the earth into +squares, and then lifting the entire square with the plant and setting +it where it is wanted. + +There are many flower-seeds which are so small that they must not be +covered at all. In this class we find begonias, petunias, and Chinese +primroses. To sow these prepare boxes as for the other seeds, and press +the earth smooth. Then scatter some fine, dry moss thinly over the +surface of the soil. Sprinkle this with water until it is well +moistened, and at once scatter the seeds thinly over the surface and +cover the boxes with panes of glass until the seeds germinate. +Transplant as soon as the young plants can be lifted out separately on +the blade of a penknife. + +[Illustration: FIG. 102. THE POET'S NARCISSUS] + +Many kinds of flower-seeds may be sowed directly in the open ground +where they are to remain. The sweet pea is one of the most popular +flowers grown in this way. The seeds should be sowed rather thickly in +rows and covered fully four inches deep. The sowing should be varied in +time according to the climate. From North Carolina southward, sweet peas +may be sowed in the fall or in January, as they are very hardy and +should be forced to bloom before the weather becomes hot. Late spring +sowing will not give fine flowers in the South. From North Carolina +northward the seeds should be sowed just as early in the spring as the +ground can be easily worked. When the plants appear, stakes should be +set along the rows and a strip of woven-wire fence stretched for the +plants to climb on. Morning-glory seeds are also sowed where they are to +grow. The seeds of the moonflower are large and hard and will fail to +grow unless they are slightly cut. To start their growth make a slight +cut just through the hard outer coat of the seed so as to expose the +white inside. In this way they will grow very readily. The seeds of the +canna, or Indian-shot plant, are treated in a similar way to start them +growing. + +[Illustration: FIG. 103. A CYCLAMEN] + +[Illustration: FIG. 104. A MODERN SWEET PEA] + +The canna makes large fleshy roots which in the North are taken up, +covered with damp moss, and stored under the benches of the greenhouse +or in a cellar. If allowed to get too dry, they will wither. From +central North Carolina south it is best to cover them up thickly with +dead leaves and let them stay in the ground where they grew. In the +early spring take them up and divide for replanting. + +[Illustration: FIG. 105. DAHLIAS] + +Perennial plants, such as our flowering shrubs, are grown from cuttings +of the ripe wood after the leaves have fallen in autumn. From North +Carolina southward these cuttings should be set in rows in the fall. +Cuttings ten inches long are set so that the tops are just even with the +ground. A light cover of pine leaves will prevent damage from frost. +Farther north the cuttings should be tied in bundles and well buried in +the ground with earth heaped over them. In the spring set them in rows +for rooting. In the South all the hardy hybrid perpetual roses can be +grown in this way, and in any section the cuttings of most of the +spring-flowering shrubs will grow in the same manner. The Japanese +quince, which makes such a show of its scarlet flowers in early spring, +can be best grown from three-inch cuttings made of the roots and planted +in rows in the fall. + +[Illustration: FIG. 106. FOUR-O'CLOCKS SET IN A GOOD PLACE] + +Many of our ornamental evergreen trees, such as the arbor vitae, can be +grown in the spring from seeds sowed in a frame. Cotton cloth should be +stretched over the trees while they are young, to prevent the sun from +scorching them. When a year old they may be set in nursery rows to +develop until they are large enough to plant. Arbor vitae may also be +grown from cuttings made by setting young tips in boxes of sand in the +fall and keeping them warm and moist through the winter. Most of them +will be rooted by spring. + +The kinds of flowers that you can grow are almost countless. You can +hardly make a mistake in selecting, as all are interesting. Start this +year with a few and gradually increase the number under your care year +by year, and aim always to make your plants the choicest of their kind. + +Of annuals there are over four hundred kinds cultivated. You may select +from the following list: phlox, petunias, China asters, California +poppies, sweet peas, pinks, double and single sunflowers, hibiscus, +candytuft, balsams, morning-glories, stocks, nasturtiums, verbenas, +mignonette. + +[Illustration: FIG. 107. A WINDOW BOX] + +Of perennials select bleeding-hearts, pinks, bluebells, hollyhocks, +perennial phlox, perennial hibiscus, wild asters, and goldenrods. From +bulbs choose crocus, tulip, daffodil, narcissus, lily of the valley, and +lily. + +Some climbers are cobaea, honeysuckle, Virginia creeper, English ivy, +Boston ivy, cypress vine, hyacinth bean, climbing nasturtiums, and +roses. + +To make your plants do best, cultivate them carefully. Allow no weeds to +grow among them and do not let the surface of the soil dry into a hard +crust. Beware, however, of stirring the soil too deep. Loosening the +soil about the roots interrupts the feeding of the plant and does harm. +Climbing plants may be trained to advantage on low woven-wire fences. +These are especially serviceable for sweet peas and climbing +nasturtiums. Do not let the plants go to seed, since seeding is a heavy +drain on nourishment. Moreover, the plant has served its end when it +seeds and is ready then to stop blossoming. You should therefore pick +off the old flowers to prevent their developing seeds. This will cause +many plants which would otherwise soon stop blossoming to continue +bearing flowers for a longer period. + +[Illustration: FIG. 108. A WINDOW-GARDEN] + +=Window-Gardening.= Growing plants indoors in the window possesses many +of the attractions of outdoor flower-gardening, and is a means of +beautifying the room at very small expense. Especially do window-gardens +give delight during the barren winter time. They are a source of culture +and pleasure to thousands who cannot afford extended and expensive +ornamentation. + +The window-garden may vary in size from an eggshell holding a minute +plant to boxes filling all the available space about the window. The +soil may be in pots for individual plants or groups of plants or in +boxes for collections of plants. You may raise your flowers inside of +the window on shelves or stands, or you may have a set of shelves built +outside of the window and inclosed in glazed sashes. The illustration on +page 119 gives an idea of such an external window-garden. + +[Illustration: FIG. 109. AN INSIDE WINDOW BOX IN ITS FULL GLORY] + +The soil must be rich and loose. The best contains some undecayed +organic matter such as leaf-mold or partly decayed sods and some sand. +Raise your plants from bulbs, cuttings, or seed, just as in outdoor +gardens. Some plants do better in cool rooms, others in a warmer +temperature. + +[Illustration: FIG. 110. MAKING THE OUTSIDE OF A WINDOW BLOOM] + +If the temperature ranges from 35 deg. to 70 deg., averaging about 55 deg., azaleas, +daisies, carnations, candytuft, alyssum, dusty miller, chrysanthemums, +cinerarias, camellias, daphnes, geraniums, petunias, violets, primroses, +and verbenas make especially good growths. + +[Illustration: A BEAUTIFUL WINDOW FLOWER] + +If the temperature is from 50 deg. to 90 deg., averaging 70 deg., try abutilon, +begonia, bouvardia, caladium, canna, Cape jasmine, coleus, fuchsia, +gloxinia, heliotrope, lantana, lobelia, roses, and smilax. + +If your box or window is shaded a good part of the time, raise begonias, +camellias, ferns, and Asparagus Sprengeri. + +[Illustration: FIG. 111. FERNS FOR BOTH INDOORS AND OUTDOORS] + +When the soil is dry, water it; then apply no more water until it again +becomes dry. Beware of too much water. The plants should be washed +occasionally with soapsuds and then rinsed. If red spiders are present, +sponge them off with water as hot as can be borne comfortably by the +hand. Newspapers afford a good means of keeping off the cold. + + + + +CHAPTER VI + +THE DISEASES OF PLANTS + + +SECTION XXVII. THE CAUSE AND NATURE OF PLANT DISEASE + +Plants have diseases just as animals do; not the same diseases, to be +sure, but just as serious for the plant. Some of them are so dangerous +that they kill the plant; others partly or wholly destroy its usefulness +or its beauty. Some diseases are found oftenest on very young plants, +others prey on the middle-aged tree, while still others attack merely +the fruit. Whenever a farmer or fruit-grower has disease on his plants, +he is sure to lose much profit. + +You have all seen rotten fruit. This is diseased fruit. Fruit rot is a +plant disease. It costs farmers millions of dollars annually. A +fruit-grower recently lost sixty carloads of peaches in a single year +through rot which could have been largely prevented if he had known how. + +Many of the yellowish or discolored spots on leaves are the result of +disease, as is also the smut of wheat, corn, and oats, the blight of the +pear, and the wilt of cotton. Many of these diseases are contagious, or, +as we often hear said of measles, "catching." This is true, among +others, of the apple and peach rots. A healthy apple can catch this +disease from a sick apple. You often see evidence of this in the apple +bin. So, too, many of the diseases found in the field or garden are +contagious. + +Sometimes when the skin of a rotten apple has been broken you will find +in the broken place a blue mold. It was this that caused the apple to +decay. This mold is a living plant; very small, certainly, but +nevertheless a plant. Let us learn a little about molds, in order that +we may better understand our apple and potato rots, as well as other +plant diseases. + +If you cut a lemon and let it stand for a day or two, there will +probably appear a blue mold like that you have seen on the surface of +canned fruit. Bread also sometimes has this blue mold; at other times +bread has a black mold, and yet again a pink or a yellow mold. + +These and all other molds are tiny living plants. Instead of seeds they +produce many very small bodies that serve the purpose of seeds and +reproduce the mold. These are called _spores_. Fig. 112 shows how they +are borne on the parent plant. + +[Illustration: FIG. 112. TANGLED THREADS OF BLUE MOLD +The single stalk on the left shows how spores are borne] + +It is also of great importance to decide whether by keeping the spores +away we may prevent mold. Possibly this experiment will help us. Moisten +a piece of bread, then dip a match or a pin into the blue mold on a +lemon, and draw the match across the moist bread. You will thus plant +the spores in a row, though they are so small that perhaps you may not +see any of them. Place the bread in a damp place for a few days and +watch it. Does the mold grow where you planted it? Does it grow +elsewhere? This experiment should prove to you that molds are living +things and can be planted. If you find spots elsewhere, you must bear in +mind that these spores are very small and light and that some of them +were probably blown about when you made your sowing. When you touch the +moldy portion of a dry lemon, you see a cloud of dust rise. This dust is +made of millions of spores. + +[Illustration: FIG. 113. MAGNIFIED ROSE MILDEW] + +If you plant many other kinds of mold you will find that the molds come +true to the kind that is planted; that like produces like even among +molds. + +[Illustration: FIG. 114. A MILDEWED ROSE] + +You can prove, also, that the mold is caused only by other mold. To do +this, put some wet bread in a wide-mouthed bottle and plug the mouth of +the bottle with cotton. Kill all the spores that may be in this bottle +by steaming it an hour in a cooking-steamer. This bread will not mold +until you allow live mold from the outside to enter. If, however, at any +time you open the bottle and allow spores to enter, or if you plant +spores therein, and if there be moisture enough, mold will immediately +set in. + +[Illustration: FIG. 115. A HIGHLY MAGNIFIED SECTION OF DISEASED PEAR LEAF +Showing how spores are borne] + +The little plants which make up these molds are called _fungi_. Some +fungi, such as the toadstools, puffballs, and devil's snuff-box, are +quite large; others, namely the molds, are very small; and others are +even smaller than the molds. Fungi never have the green color of +ordinary plants, always reproduce by spores, and feed on living matter +or matter that was once alive. Puffballs, for example, are found on +rotting wood or dead twigs or roots. Some fungi grow on living plants, +and these produce plant disease by taking their nourishment from the +plant on which they grow; the latter plant is called the _host_. + +The same blue mold that grows on bread often attacks apples that have +been slightly bruised; it cannot pierce healthy apple skin. You can +plant the mold in the bruised apple just as you did on bread and watch +its rapid spread through the apple. You learn from this the need of +preventing bruised or decayed apples from coming in contact with healthy +fruit. + +[Illustration: FIG. 116. SPORES OF THE PEAR SCAB +The spores are borne on stalks] + +Just as the fungus studied above lives in the apple or bread, so other +varieties live on leaves, bark, etc. Fig. 113 represents the surface of +a mildewed rose leaf greatly magnified. This mildew is a fungus. You can +see its creeping stems, its upright stalk, and numerous spores ready to +fall off and spread the disease with the first breath of wind. You must +remember that this figure is greatly magnified, and that the whole +portion shown in the figure is only about one tenth of an inch across. +Fig. 114 shows the general appearance of a twig affected by this +disease. + +Mildew on the rose or on any other plant may be killed by spraying the +leaves with a solution of liver of sulphur; to make this solution, use +one ounce of the liver of sulphur to two gallons of water. + +The fungus that causes the pear-leaf spots has its spores in little pits +(Fig. 115). The spores of some fungi also grow on stalks, as shown in +Fig. 116. This figure represents an enlarged view of the pear scab, +which causes so much destruction. + +You see, then, that fungi are living plants that grow at the expense of +other plants and cause disease. Now if you can cover the leaf with a +poison that will kill the spore when it comes, you can prevent the +disease. One such poison is the Bordeaux (_bor-do_') mixture, which +has proved of great value to farmers. + +Since the fungus in most cases lives within the leaves, the poison on +the outside does no good after the fungus is established. The treatment +can be used only to _prevent_ attack, not to cure, except in the case of +a few mildews that live on the outside of the leaf, as does the rose +mildew. + + + =EXERCISE= + + Why do things mold more readily in damp places? Do you now + understand why fruit is heated before it is canned? Try to grow + several kinds of mold. Do you know any fungi which may be eaten? + + Transfer disease from a rotten apple to a healthy one and note the + rapidity of decay. How many really healthy leaves can you find on a + strawberry plant? Do you find any spots with reddish borders and + white centers? Do you know that this is a serious disease of the + strawberry? What damage does fruit mold do to peaches, plums, or + strawberries? + + Write to your experiment station for bulletins on plant diseases + and methods for making and using spraying mixtures. + + +SECTION XXVIII. YEAST AND BACTERIA + +Can you imagine a plant so small that it would take one hundred plants +lying side by side to equal the thickness of a sheet of writing-paper? +There are plants that are so small. Moreover, these same plants are of +the utmost importance to man. Some of them do him great injury, while +others aid him very much. + +You will see their importance when you are told that certain of them in +their habits of life cause great change in the substances in which they +live. For example, when living in a sugary substance they change the +sugar into a gas and an alcohol. Do you remember the bright bubbles of +gas you have seen rising in sweet cider or in wine as it soured? These +bubbles are caused by one of these small plants--the yeast plant. As the +yeast plant grows in the sweet fruit juice, alcohol is made and a gas is +given off at the same time, and this gas makes the bubbles. + +[Illustration: FIG. 117. YEAST PLANTS +_A_, a single plant; _B_, group of two budding cells; _C_, group of +several cells] + +Later, other kinds of plants equally small will grow and change the +alcohol into an acid which you will recognize as vinegar by its sour +taste and peculiar odor. Thus vinegar is made by the action of two +different kinds of little living plants in the cider. That these are +living beings you can prove by heating the cider and keeping it tightly +sealed so that nothing can enter it. You will find that because the +living germs have been killed by the heat, the cider will not ferment or +sour as it did before. The germs could of course be killed by poisons, +but then the cider would be unfit for use. It is this same little yeast +plant that causes bread to rise. + +When you see any decaying matter you may know that in it minute plants +much like the yeast plant are at work. Since decay is due to them, we +take advantage of the fact that they cannot grow in strong brine or +smoke; and we prepare meat for keeping by salting it or by smoking it or +by both of these methods. + +You see that some of the yeast plants and _bacteria_, as many of these +forms are called, are very friendly to us, while others do us great +harm. + +Some bacteria grow within the bodies of men and other animals or in +plants. When they do so they may produce disease. Typhoid fever, +diphtheria, consumption, and many other serious diseases are caused by +bacteria. Fig. 118, _e_, shows the bacterium that causes typhoid fever. +In the picture, of course, it is very greatly magnified. In reality +these bacteria are so small that about twenty-five thousand of them side +by side would extend only one inch. These small beings produce their +great effects by very rapid multiplication and by giving off powerful +poisons. + +[Illustration: FIG. 118. FORMS OF BACTERIA +_a_, grippe; _b_, bubonic plague; _c_, diphtheria; _d_, tuberculosis; +_e_, typhoid fever] + +Bacteria are so small that they are readily borne on the dust particles +of the air and are often taken into the body through the breath and also +through water or milk. You can therefore see how careful you should be +to prevent germs from getting into the air or into water or milk when +there is disease about your home. You should heed carefully all +instructions of your physician on this point, so that you may not spread +disease. + + +SECTION XXIX. PREVENTION OF PLANT DISEASE + +In the last two sections you have learned something of the nature of +those fungi and bacteria that cause disease in animals and plants. Now +let us see how we can use this knowledge to lessen the diseases of our +crops. Farmers lose through plant diseases much that could be saved by +proper precaution. + +First, you must remember that every diseased fruit, twig, or leaf bears +millions of spores. These must be destroyed by burning. They must not be +allowed to lie about and spread the disease in the spring. See that +decayed fruit in the bin or on the trees is destroyed in the same +manner. Never throw decayed fruit into the garden or orchard, as it may +cause disease the following year. + +Second, you can often kill spores on seeds before they are planted and +thus prevent the development of the fungus (see pp. 134-137). + +Third, often the foliage of the plant can be sprayed with a poison that +will prevent the germination of the spores (see pp. 138-140). + +Fourth, some varieties of plants resist disease much more stoutly than +others. We may often select the resistant form to great advantage (see +Fig. 119). + +Fifth, after big limbs are pruned off, decay often sets in at the wound. +This decay may be prevented by coating the cut surface with paint, tar, +or some other substance that will not allow spores to enter the wound or +to germinate there. + +Sixth, it frequently happens that the spore or fungus remains in the +soil. This is true in the cotton wilt, and the remedy is so to rotate +crops that the diseased land is not used again for this crop until the +spores or fungi have died. + + +SECTION XXX. SOME SPECIAL PLANT DISEASES + +=Fire-Blight of the Pear and Apple.= You have perhaps heard your father +speak of the "fire-blight" of pear and apple trees. This is one of the +most injurious and most widely known of fruit diseases. Do you want to +know the cause of this disease and how to prevent it? + +First, how will you recognize this disease? If the diseased bough at +which you are looking has true fire-blight, you will see a blackened +twig with withered, blackened leaves. During winter the leaves do not +fall from blighted twigs as they do from healthy ones. The leaves wither +because of the diseased twig, not because they are themselves diseased. +Only rarely does the blight really enter the leaf. Sometimes a sharp +line separates the blighted from the healthy part of the twig. + +This disease is caused by bacteria, of which you have read in another +section. The fire-blight bacteria grow in the juicy part of the stem, +between the wood and the bark. This tender, fresh layer (as explained on +page 79) is called the _cambium_, and is the part that breaks away and +allows you to slip the bark off when you make your bark whistle in the +spring. The growth of new wood takes place in the cambium, and this part +of the twig is therefore full of nourishment. If this nourishment is +stolen the plant of course soon suffers. + +The bacteria causing fire-blight are readily carried from flower to +flower and from twig to twig by insects; therefore to keep these and +other bacteria away from your trees you must see to it that all the +trees in the neighborhood of your orchard are kept free from mischievous +enemies. If harmful bacteria exist in near-by trees, insects will carry +them to your orchard. You must therefore watch all the relatives of the +pear; namely, the apple, hawthorn, crab, quince, and mountain ash, for +any of these trees may harbor the germs. + +[Illustration: FIG. 119. A RESISTANT VARIETY OF SEA ISLAND COTTON +All the other plants in this field died. This one row lived because it +could resist the cotton wilt] + +When any tree shows blight, every diseased twig on it must be cut off +and burned in order to kill the germs, and you must cut low enough on +the twig to get all the bacteria. It is best to cut a foot below the +blackened portion. If by chance your knife should cut into wood +containing the living germs, and then you should cut into healthy wood +with the same knife, you yourself would spread the disease. It is +therefore best after each cutting to dip your knife into a solution of +carbolic acid. This will kill all bacteria clinging to the knife-blade. +The surest time to do complete trimming is after the leaves fall in the +autumn, as diseased twigs are most easily recognized at that time, but +the orchard should be carefully watched in the spring also. If a large +limb shows the blight, it is perhaps best to cut the tree entirely down. +There is little hope for such a tree. + +A large pear-grower once said that no man with a sharp knife need fear +the fire-blight. Yet our country loses greatly by this disease each +year. + +[Illustration: FIG. 120. FIRE-BLIGHT BACTERIA +Magnified] + +It may be added that winter pruning tends to make the tree form much new +wood and thus favors the disease. Rich soil and fertilizers make it much +easier in a similar way for the tree to become a prey to blight. + + + =EXERCISE= + + Ask your teacher to show you a case of fire-blight on a pear or + apple tree. Can you distinguish between healthy and diseased wood? + Cut the twig open lengthwise and see how deep into the wood and how + far down the stem the disease extends. Can you tell surely from the + outside how far the twig is diseased? Can you find any twig that + does not show a distinct line of separation between diseased and + healthy wood? If so, the bacteria are still living in the cambium. + Cut out a small bit of the diseased portion and insert it under the + bark of a healthy, juicy twig within a few inches of its tip and + watch it from day to day. Does the tree catch the disease? This + experiment may prove to you how easily the disease spreads. If you + should see any drops like dew hanging from diseased twigs, touch a + little of this moisture to a healthy flower and watch for results. + + Cut and burn all diseased twigs that you can find. Estimate the + damage done by fire-blight. + + Farmers' bulletins on orchard enemies are published by the + Department of Agriculture, Washington, D.C., and can be had by + writing for them. They will help your father much in treating + fire-blight. + + +=Oat Smuts.= Let us go out into a near-by oat field and look for all the +blackened heads of grain that we can find. How many are there? To count +accurately let us select an area one foot square. We must look +carefully, for many of these blackened heads are so low that we shall +not see them at the first glance. You will be surprised to find as many +as thirty or forty heads in every hundred so blackened. These blackened +heads are due to a plant disease called _smut_. + +[Illustration: FIG. 121. LOOSE SMUT OF OATS +The glumes at _a_ more nearly destroyed than the glumes at _b_] + +When threshing-time comes you will notice a great quantity of black dust +coming from the grain as it passes through the machine. The air is full +of it. This black dust consists of the spores of a tiny fungous plant. +The fungous smut plant grows upon the oat plant, ripens its spores in +the head, and is ready to be thoroughly scattered among the grains of +the oats as they come from the threshing-machine. + +These spores cling to the grain and at the next planting are ready to +attack the sprouting plantlet. A curious thing about the smut is that it +can gain a foothold only on very young oat plants; that is, on plants +about an inch long or of the age shown in Fig. 121. + +When grain covered with smut spores is planted, the spores develop with +the sprouting seeds and are ready to attack the young plant as it breaks +through the seed-coat. You see, then, how important it is to have seed +grain free from smut. A substance has been found that will, without +injuring the seeds, kill all the smut spores clinging to the grain. This +substance is called _formalin_. Enough seed to plant a whole acre can be +treated with formalin at a cost of only a few cents. Such treatment +insures a full crop and clean seed for future planting. Try it if you +have any smut. + +[Illustration: FIG. 122. A CROP FROM OATS TREATED WITH FORMALIN] + +Fig. 122 illustrates what may be gained by using seeds treated to +prevent smut. The annual loss to the farmers of the United States from +smut on oats amounts to several millions of dollars. All that is needed +to prevent this loss is a little care in the treatment of seed and a +proper rotation of crops. + + + =EXERCISE= + + Count the smutted heads on a patch three feet square and estimate + the percentage of smut in all the wheat and oat fields near your + home. On which is it most abundant? Do you know of any fields that + have been treated for smut? If so, look for smut in these fields. + Ask how they were treated. Do you know of any one who uses + bluestone for wheat smut? Can oats be treated with bluestone? + + At planting time get an ounce of formalin at your drug store or + from the state experiment station. Mix this with three gallons of + water. This amount will treat three bushels of seeds. Spread the + seeds thinly on the barn floor and sprinkle them with the mixture, + being careful that all the seeds are thoroughly moistened. Cover + closely with blankets for a few hours and plant very soon after + treatment. Try this and estimate the per cent of smut at next + harvest-time. Write to your experiment station for a bulletin on + smut treatment. + +[Illustration: FIG. 123. A SCABBY SEED POTATO] + +[Illustration: FIG. 124. A HEALTHY SEED POTATO] + +=Potato Scab.= The scab of the white, or Irish, potato is one of the +commonest and at the same time most easily prevented of plant diseases. +Yet this disease diminishes the profits of the potato-grower very +materially. Fig. 123 shows a very scabby potato, while Fig. 124 +represents a healthy one. This scab is caused by a fungous growth on the +surface of the potato. Of course it lessens the selling-price of the +potatoes. If seed potatoes be treated to a bath of formalin just before +they are planted, the formalin will kill the fungi on the potatoes and +greatly diminish the amount of scab at the next harvest. Therefore +before they are planted, seed potatoes should be soaked in a weak +solution of formalin for about two hours. One-half pint of formalin to +fifteen gallons of water makes a proper solution. + +[Illustration: FIG. 125 +From a scabby potato, like the one in Fig. 123, this yield was obtained] + +[Illustration: FIG. 126 +From a healthy potato, like the one in Fig. 124, this yield was obtained] + +[Illustration: FIG. 127. EFFECT OF SPRAYING +Sprayed potatoes on left; unsprayed on right] + +One pint of formalin, or enough for thirty gallons of water, will cost +but thirty-five cents. Since this solution can be used repeatedly, it +will do for many bushels of seed potatoes. + +=Late Potato Blight.= The blight is another serious disease of the +potato. This is quite a different disease from the scab and so requires +different treatment. The blight is caused by another fungus, which +attacks the foliage of the potato plant. When the blight seriously +attacks a crop, it generally destroys the crop completely. In the year +1845 a potato famine extending over all the United States and Europe was +caused by this disease. + +[Illustration: FIG. 128. YIELD FROM TWO FIELDS OF THE SAME SIZE +The one at the top was sprayed; the one at the bottom was unsprayed] + +Spraying is the remedy for potato blight. Fig. 128 shows the effect of +spraying upon the yield. In this case the sprayed field yielded three +hundred and twenty-four bushels an acre, while the unsprayed yielded +only one hundred bushels to an acre. Fig. 127 shows the result of three +applications of the spraying mixture on the diseased field. Figs. 129 +and 130 show how the spraying is done. + +[Illustration: FIG. 129. SPRAYING MACHINE] + +[Illustration: FIG. 130. SPRAYING MACHINE] + + + =EXERCISE= + + Watch the potatoes at the next harvest and estimate the number that + is damaged by scab. You will remember that formalin is the + substance used to prevent grain smuts. Write to your state + experiment station for a bulletin telling how to use formalin, as + well as for information regarding other potato diseases. Give the + treatment a fair trial in a portion of your field this year and + watch carefully for results. Make an estimate of the cost of + treatment and of the profits. How does the scab injure the value of + the potato? The late blight can often be recognized by its odor. + Did you ever smell it as you passed an affected field? + +[Illustration: FIG. 131. CLUB ROOT] + +=Club Root.= Club root is a disease of the cabbage, turnip, cauliflower, +etc. Its general effect is shown in the illustration (Fig. 131). +Sometimes this disease does great damage. It can be prevented by using +from eighty to ninety bushels of lime to an acre. + +=Black Knot.= Black knot is a serious disease of the plum and of the +cherry tree. It attacks the branches of the tree; it is well +illustrated in Fig. 132. Since it is a contagious disease, great care +should be exercised to destroy all diseased branches of either wild or +cultivated plums or cherries. In many states its destruction is enforced +by law. All black knot should be cut out and burned some time before +February of each year. This will cost little and save much. + +[Illustration: FIG. 132. BLACK KNOT] + +=Peach Leaf Curl.= Peach leaf curl does damage amounting to about +$3,000,000 yearly in the United States. It can be almost entirely +prevented by spraying the tree with Bordeaux mixture or lime-sulphur +wash before the buds open in the spring. It is not safe to use strong +Bordeaux mixture on peach trees when they are in leaf. + +[Illustration: FIG. 133. MOLDY PEACHES] + +=Cotton Wilt.= Cotton wilt when it once establishes itself in the soil +completely destroys the crop. The fungus remains in the soil, and no +amount of spraying will kill it. The only known remedy is to cultivate a +resistant variety of cotton or to rotate the crop. + +[Illustration: FIG. 134. PEACH MUMMIES] + +=Fruit Mold.= Fruit mold, or brown rot, often attacks the unripe fruit +on the tree, and turns it soft and brown and finally fuzzy with a coat +of mildew. Fig. 133 shows some peaches thus attacked. Often the fruits +do not fall from the trees but shrivel up and become "mummies" (Fig. +134). This rot is one of the most serious diseases of plums and peaches. +It probably diminishes the value of the peach harvest from 50 to 75 per +cent. Spraying according to the directions in the Appendix will kill the +disease. + +[Illustration: FIG. 135. HALF OF TREE SPRAYED TO PREVENT PEACH CURL +Note the difference in foliage and fruit on the sprayed and unsprayed +halves of the tree, and the difference in yield shown below] + + + + +CHAPTER VII + +ORCHARD, GARDEN, AND FIELD INSECTS + + +SECTION XXXI. INSECTS IN GENERAL + +The farmer who has fought "bugs" on crop after crop needs no argument to +convince him that insects are serious enemies to agriculture. Yet even +he may be surprised to learn that the damage done by them, as estimated +by good authority, amounts to millions and millions of dollars yearly in +the United States and Canada. + +[Illustration: FIG. 136. ANTS] + +Every one thinks he knows what an insect is. If, however, we are willing +in this matter to make our notion agree with that of the people who have +studied insects most and know them best, we must include among the true +insects only such air-breathing animals as have six legs, no more, and +have the body divided into three parts--head, thorax, and abdomen. These +parts are clearly shown in Fig. 136, which represents the ant, a true +insect. All insects do not show the divisions of the body so clearly as +this figure shows them, but on careful examination you can usually make +them out. The head bears one pair of feelers, and these in many insects +serve also as organs of smell and sometimes of hearing. Less prominent +feelers are to be found in the region of the mouth. These serve as +organs of taste. + +[Illustration: FIG. 137. PARTS OF AN INSECT] + +[Illustration: FIG. 138. COMPOUND EYE OF DRAGON FLY] + +The eyes of insects are especially noticeable. Close examination shows +them to be made up of a thousand or more simple eyes. Such an eye is +called a _compound eye_. An enlarged view of one of these is shown in +Fig. 138. + +Attached to the thorax are the legs and also the wings, if the insect +has wings. The rear portion is the abdomen, and this, like the other +parts, is composed of parts known as segments. The insect breathes +through openings in the abdomen and thorax called _spiracles_ (see Fig. +137). + +An examination of spiders, mites, and ticks shows eight legs; therefore +these do not belong to the true insects, nor do the thousand-legged +worms and their relatives. + +[Illustration: FIG. 139. THE HOUSE FLY +_a_, egg; _b_, larva, or maggot; _c_, pupa; _d_, adult male. (All +enlarged)] + +The chief classes of insects are as follows: the flies, with two wings +only; the bees, wasps, and ants, with four delicate wings; the beetles, +with four wings--two hard, horny ones covering the two more delicate +ones. When the beetle is at rest its two hard wings meet in a straight +line down the back. This peculiarity distinguishes it from the true bug, +which has four wings. The two outer wings are partly horny, and in +folding lap over each other. Butterflies and moths are much alike in +appearance but differ in habit. The butterfly works by day and the moth +by night. Note the knob on the end of the butterfly's feeler (Fig. 143). +The moth has no such knob. + +It is important to know how insects take their food, for by knowing this +we are often able to destroy insect pests. Some are provided with mouth +parts for chewing their food; others have a long tube with which they +pierce plants or animals and, like the mosquito, suck their food from +the inside. Insects of this latter class cannot of course be harmed by +poison on the surface of the leaves on which they feed. + +[Illustration: FIG. 140. A TYPICAL BUG +_a_, adult; _b_, side view of sucking mouth-part Both _a_ and _b_ are +much enlarged] + +[Illustration: Fig. 141. BEETLE +_a_, larva; _b_, pupa; _c_, adult; _d_, burrow] + +Many insects change their form from youth to old age so much that you +can scarcely recognize them as the same creatures. First comes the egg. +The egg hatches into a worm-like animal known as a grub, maggot, or +caterpillar, or, as scientists call it, a _larva_. This creature feeds +and grows until finally it settles down and spins a home of silk, called +a _cocoon_ (Fig. 145). If we open the cocoon we shall find that the +animal is now covered with a hard outside skeleton, that it cannot move +freely, and that it cannot eat at all. The animal in this state is known +as the _pupa_ (Figs. 145 and 146). Sometimes, however, the pupa is not +covered by a cocoon, sometimes it is soft, and sometimes it has some +power of motion (Fig. 141). After a rest in the pupa stage the animal +comes out a mature insect (Figs. 142 and 143). + +From this you can see that it is especially important to know all you +can about the life of injurious insects, since it is often easier to +kill these pests at one stage of their life than at another. Often it is +better to aim at destroying the seemingly harmless beetle or butterfly +than to try to destroy the larvae that hatch from its eggs, although, as +you must remember, it is generally the larvae that do the most harm. +Larvae grow very rapidly; therefore the food supply must be great to meet +the needs of the insect. + +[Illustration: FIG. 142. MOTH AND COCOON] + +Some insects, the grasshopper for example, do not completely change +their form. Fig. 147 represents some young grasshoppers, which very +closely resemble their parents. + +[Illustration: FIG. 143. BUTTERFLY] + +[Illustration: FIG. 144. STRUCTURE OF THE CATERPILLAR] + +[Illustration: FIG. 145. MOTH PUPA IN COCOON] + +Insects lay many eggs and reproduce with remarkable rapidity. Their +number therefore makes them a foe to be much dreaded. The queen honeybee +often lays as many as 4000 eggs in twenty-four hours. A single house fly +lays between 100 and 150 eggs in one day. The mosquito lays eggs in +quantities of from 200 to 400. The white ant often lays 80,000 in a day, +and so continues for two years, probably laying no less than 40,000,000 +eggs. In one summer the bluebottle fly could have 500,000,000 +descendants if they all lived. The plant louse, at the end of the fifth +brood, has laid in a single year enough eggs to produce 300,000,000 +young. Of course every one knows that, owing to enemies and diseases +(for the insects have enemies which prey on them just as they prey on +plants) comparatively few of the insects hatched from these eggs live +till they are grown. + +[Illustration: FIG. 146. A BUTTERFLY PUPA +Note outline of the butterfly] + +The number of insects which are hurtful to crops, gardens, flowers, and +forests seems to be increasing each season. Therefore farm boys and +girls should learn to recognize these harmful insects and to know how +they live and how they may be destroyed. Those who know the forms and +habits of these enemies of plants and trees are far better prepared to +fight them than are those who strike in the dark. Moreover such +knowledge is always a source of interest and pleasure. If you begin to +study insects, you will soon find your love for the study growing. + +[Illustration: FIG. 147. THE GROWTH OF A GRASSHOPPER] + + + =EXERCISE= + + Collect cocoons and pupae of insects and hatch them in a + breeding-cage similar to the one illustrated in Fig. 149. Make + several cages of this kind. Collect larvae of several kinds; supply + them with food from plants upon which you found them. Find out the + time it takes them to change into another stage. Write a + description of this process. + + The plant louse could produce in its twelfth brood + 10,000,000,000,000,000,000,000 offspring. Each louse is about one + tenth of an inch long. If all should live and be arranged in single + file, how many miles long would such a procession be? + +[Illustration: FIG. 148. PLANT LICE] + +[Illustration: FIG. 149. CAGE IN WHICH TO BREED INSECTS +Flower-pot, lamp-chimney, and cloth] + + +SECTION XXXII. ORCHARD INSECTS + +=The San Jose Scale.= The San Jose scale is one of the most dreaded +enemies of fruit trees. It is in fact an outlaw in many states. It is an +unlawful act to sell fruit trees affected by it. Fig. 150 shows a view +of a branch nearly covered with this pest. Although this scale is a very +minute animal, yet so rapidly does it multiply that it is very +dangerous to the tree. Never allow new trees to be brought into your +orchard until you feel certain that they are free from the San Jose +scale. If, however, it should in any way gain access to your orchard, +you can prevent its spreading by thorough spraying with what is known as +the lime-sulphur mixture. This mixture has long been used on the Pacific +coast as a remedy for various scale insects. When it was first tried in +other parts of the United States the results were not satisfactory and +its use was abandoned. However, later experiments with it have proved +that the mixture is thoroughly effective in killing this scale and that +it is perfectly harmless to the trees. Until the lime-sulphur mixture +proved to be successful the San Jose scale was a most dreaded nursery +and orchard foe. It was even thought necessary to destroy infected +trees. The lime-sulphur mixture and some other sulphur washes not only +kill the San Jose scale but are also useful in reducing fungous injury. + +[Illustration: FIG. 150 SAN JOSE SCALE] + +[Illustration: FIG. 151. SINGLE SAN JOSE SCALE +Magnified] + +There are several ways of making the lime-sulphur mixture. It is +generally best to buy a prepared mixture from some trustworthy dealer. +If you find the scale on your trees, write to your state experiment +station for directions for combating it. + +[Illustration: FIG. 152. THE CODLING MOTH +_a_, burrow of worm in apple; _b_, place where worm enters; _c_, place +where worm leaves; _e_, the larva; _d_, the pupa; _i_, the cocoon; _f_ +and _g_, moths; _h_, magnified head of larva] + +=The Codling Moth.= The codling moth attacks the apple and often causes +a loss of from twenty-five to seventy-five per cent of the crop. In the +state of New York this insect is causing an annual loss of about three +million dollars. The effect it has on the fruit is most clearly seen in +Fig. 152. The moth lays its egg upon the young leaves just after the +falling of the blossom. She flies on from apple to apple, depositing an +egg each time until from fifty to seventy-five eggs are deposited. The +larva, or "worm," soon hatches and eats its way into the apple. Many +affected apples ripen too soon and drop as "windfalls." Others remain on +the tree and become the common wormy apples so familiar to growers. The +larva that emerges from the windfalls moves generally to a tree, crawls +up the trunk, and spins its cocoon under a ridge in the bark. From the +cocoon the moth comes ready to start a new generation. The last +generation of the larvae spends the winter in the cocoon. + +[Illustration: FIG. 153. SPRAYING THE ORCHARD BRINGS LUSCIOUS FRUIT +The picture in the corner at the top shows the right time to spray for +codling moth] + +_Treatment._ Destroy orchard trash which may serve as a winter home. +Scrape all loose bark from the tree. Spray the tree with arsenate of +lead as soon as the flowers fall. A former method of fighting this pest +was as follows: bands of burlap four inches wide tied around the tree +furnished a hiding-place for larvae that came from windfalls or crawled +from wormy apples on the tree. The larvae caught under the bands were +killed every five or six days. We know now, however, that a thorough +spraying just after the blossoms fall kills the worms and renders the +bands unnecessary. Furthermore, spraying prevents wormy apples, while +banding does not. Follow the first spraying by a second two weeks later. + +It is best to use lime-sulphur mixture or the Bordeaux mixture with +arsenate of lead for a spray. Thus one spraying serves against both +fungi and insects. + +[Illustration: FIG. 154. PLUM CURCULIO +Larva, pupa, adult, and mark on the fruit. (Enlarged)] + +=The Plum Curculio.= The plum curculio, sometimes called the plum +weevil, is a little creature about one fifth of an inch long. In spite +of its small size the curculio does, if neglected, great damage to our +fruit crop. It injures peaches, plums, and cherries by stinging the +fruit as soon as it is formed. The word "stinging" when applied to +insects--- and this case is no exception--means piercing the object +with the egg-layer (ovipositor) and depositing the egg. Some insects +occasionally use the ovipositor merely for defense. The curculio has an +especially interesting method of laying her egg. First she digs a hole, +in which she places the egg and pushes it well down. Then with her snout +she makes a crescent-shaped cut in the skin of the plum, around the egg. +This mark is shown in Fig. 154. As this peculiar cut is followed by a +flow of gum, you will always be able to recognize the work of the +curculio. Having finished with one plum, this industrious worker makes +her way to other plums until her eggs are all laid. The maggotlike larva +soon hatches, burrows through the fruit, and causes it to drop before +ripening. The larva then enters the ground to a depth of several inches. +There it becomes a pupa, and later, as a mature beetle, emerges and +winters in cracks and crevices. + +[Illustration: FIG. 155. LEAF GALLS OF PHYLLOXERA ON CLINTON GRAPE LEAF] + +_Treatment._ Burn orchard trash which may serve as winter quarters. +Spraying with arsenate of lead, using two pounds of the mixture to fifty +gallons of water, is the only successful treatment for the curculio. For +plums and peaches, spray first when the fruit is free from the calyx +caps, or dried flower-buds. Repeat the spraying two weeks later. For +late peaches spray a third time two weeks after the second spraying. +This poisonous spray will kill the beetles while they are feeding or +cutting holes in which to lay their eggs. + +[Illustration: FIG. 156. THE CANKERWORM] + +Fowls in the orchard do good by capturing the larvae before they can +burrow, while hogs will destroy the fallen fruit before the larvae can +escape. + +=The Grape Phylloxera.= The grape phylloxera is a serious pest. You have +no doubt seen its galls upon the grape leaf. These galls are caused by a +small louse, the phylloxera. Each gall contains a female, which soon +fills the gall with eggs. These hatch into more females, which emerge +and form new galls, and so the phylloxera spreads (see Fig. 155). + +_Treatment._ The Clinton grape is most liable to injury from this pest. +Hence it is better to grow other more resistant kinds. Sometimes the +lice attack the roots of the grape vines. In many sections where +irrigation is practiced the grape rows are flooded when the lice are +thickest. The water drowns the lice and does no harm to the vines. + +=The Cankerworm.= The cankerworm is the larva of a moth. Because of its +peculiar mode of crawling, by looping its body, it is often called the +looping worm or measuring worm (Fig. 157, _c_). These worms are such +greedy eaters that in a short time they can so cut the leaves of an +orchard as to give it a scorched appearance. Such an attack practically +destroys the crop and does lasting injury to the tree. The worms are +green or brown and are striped lengthwise. If the tree is jarred, the +worm has a peculiar habit of dropping toward the ground on a silken +thread of its own making (Fig. 156). + +[Illustration: FIG. 157. THE SPRING CANKERWORM +_a_, egg mass; _b_, egg, magnified; _c_, larva; _d_, female moth; _e_, +male moth] + +In early summer the larvae burrow within the earth and pupate there; +later they emerge as adults (Fig. 157, _d_ and _e_). You observe the +peculiar difference between the wingless female, _d_, and the winged +male, _e_. It is the habit of this wingless female to crawl up the trunk +of some near-by tree in order to deposit her eggs upon the twigs. These +eggs (shown at _a_ and _b_) hatch into the greedy larvae that do so much +damage to our orchards. + +Nearly all the common birds feed freely upon the cankerworm, and benefit +the orchard in so doing. The chickadee is perhaps the most useful. A +recent writer is very positive that each chickadee will devour on an +average thirty female cankerworm moths a day; and that if the average +number of eggs laid by each female is one hundred and eighty-five, one +chickadee would thus destroy in one day five thousand five hundred and +fifty eggs, and, in the twenty-five days in which the cankerworm moths +crawl up the tree, would rid the orchard of one hundred and thirty-eight +thousand seven hundred and fifty. These birds also eat immense numbers +of cankerworm eggs before they hatch into worms. + +[Illustration: FIG. 158. EGGS OF THE FALL CANKERWORM] + +_Treatment._ The inability of the female to fly gives us an easy way to +prevent the larval offspring from getting to the foliage of our trees, +for we know that the only highway open to her or her larvae leads up the +trunk. We must obstruct this highway so that no crawling creature may +pass. This is readily done by smoothing the bark and fitting close to it +a band of paper, and making sure that it is tight enough to prevent +anything from crawling underneath. Then smear over the paper something +so sticky that any moth or larva that attempts to pass will be +entangled. Printer's ink will do very well, or you can buy either +dendrolene or tanglefoot. + +[Illustration: FIG. 159. APPLE-TREE TENT CATERPILLAR +_a_, eggs; _b_, cocoon; _c_, caterpillar] + +Encourage the chickadee and all other birds, except the English sparrow, +to stay in your orchard. This is easily done by feeding and protecting +them in their times of need. + +=The Apple-Tree Tent Caterpillar.= The apple-tree tent caterpillar is a +larva so well known that you only need to be told how to guard against +it. The mother of this caterpillar is a reddish moth. This insect passes +the winter in the egg state securely fastened on the twigs as shown in +Fig. 159, _a_. + +_Treatment._ There are three principal methods, (1) Destroy the eggs. +The egg masses are readily seen in winter and may easily be collected +and burned by boys. The chickadee eats great quantities of these eggs. +(2) With torches burn the nests at dusk when all the worms are within. +You must be very careful in burning or you will harm the young branches +with their tender bark. (3) Encourage the residence of birds. Urge your +neighbors to make war on the larvae, too, since the pest spreads rapidly +from farm to farm. Regularly sprayed orchards are rarely troubled by +this pest. + +[Illustration: FIG. 160. THE TWIG GIRDLER AT ITS DESTRUCTIVE WORK +_a_, the girdler; _b_, the egg-hole; _c_, the groove cut by girdler; +_e_, the egg] + +=The Twig Girdler.= The twig girdler lays her eggs in the twigs of pear, +pecan, apple, and other trees. It is necessary that the larvae develop in +dead wood. This the mother provides by girdling the twig so deeply that +it will die and fall to the ground. + +_Treatment._ Since the larvae spend the winter in the dead twigs, burn +these twigs in autumn or early spring and thus destroy the pest. + +=The Peach-Tree Borer.= In Fig. 161 you see the effect of the peach-tree +borer's activity. These borers often girdle and thereby kill a tree. +Fig. 162 shows the adult state of the insect. The eggs are laid on peach +or plum trees near the ground. As soon as the larva emerges, it bores +into the bark and remains there for months, passing through the pupa +stage before it comes out to lay eggs for another generation. + +[Illustration: FIG. 161. BORER SIGNS AROUND BASE OF PEACH TREE] + +_Treatment._ If there are only a few trees in the orchard, digging the +worms out with a knife is the best way of destroying them. You can know +of the borer's presence by the exuding gum often seen on the tree-trunk. +If you pile earth around the roots early in the spring and remove it in +the late fall, the winter freezing and thawing will kill many of the +larvae. + + + =EXERCISE= + + How many apples per hundred do you find injured by the codling + moth? Collect some cocoons from a pear or an apple tree in winter, + place in a breeding-cage, and watch for the moths that come out. Do + you ever see the woodpecker hunting for these same cocoons? Can you + find cocoons that have been emptied by this bird? Estimate how many + he considers a day's ration. How many apples does he thus save? + + [Illustration: FIG. 162. PEACH-TREE BORERS, MALE AND FEMALE + Female with broad yellow band across abdomen] + + Watch the curculio lay her eggs in the plums, peaches, or cherries. + What per cent of fruit is thus injured? Estimate the damage. Let + the school offer a prize for the greatest number of + tent-caterpillar eggs. Watch such trees as the apple, the wild and + the cultivated cherry, the oak, and many others. + + Make a collection of insects injurious to orchard fruits, showing + in each case the whole life history of the insect, that is, eggs, + larva, pupa, and the mature insects. + +[Illustration: THE TROUBLESOME CHINCH BUG (ENLARGED) +1, bugs on plant; 2, eggs; 3, young bug; 4 and 5, older bugs; 6, +long-winged bug; 7 and 8, short-winged bug] + + +SECTION XXXIII. GARDEN AND FIELD INSECTS + +=The Cabbage Worm.= The cabbage worm of the early spring garden is a +familiar object, but you may not know that the innocent-looking little +white butterflies hovering about the cabbage patch are laying eggs which +are soon to hatch and make the dreaded cabbage worms. In Fig. 164 _a_ +and _b_ show the common cabbage butterfly, _c_ shows several examples of +the caterpillar, and _d_ shows the pupa case. In the pupa stage the +insects pass the winter among the remains of old plants or in near-by +fences or in weeds or bushes. Cleaning up and burning all trash will +destroy many pupae and thus prevent many cabbage worms. In Fig. 164 _e_ +and _f_ show the moth and zebra caterpillar; _g_ represents a moth which +is the parent of the small green worm shown at _h_. This worm is a +common foe of the cabbage plant. + +[Illustration: FIG. 163. THE DREADED CHINCH BUG] + +_Treatment._ Birds aid in the destruction of this pest. Paris green +mixed with air-slaked lime will also kill many larvae. After the cabbage +has headed, it is very difficult to destroy the worm, but pyrethrum +insect powder used freely is helpful. + +=The Chinch Bug.= The chinch bug, attacking as it does such important +crops as wheat, corn, and grasses, is a well-known pest. It probably +causes more money loss than any other garden or field enemy. In Orange +county, North Carolina, farmers were once obliged to suspend +wheat-growing for two years on account of the chinch bug. In one year in +the state of Illinois this bug caused a loss of four million dollars. + +[Illustration: FIG. 164. CABBAGE WORMS AND BUTTERFLIES] + +_Treatment._ Unfortunately we cannot prevent all of the damage done by +chinch bugs, but we can diminish it somewhat by good clean agriculture. +Destroy the winter homes of the insect by burning dry grass, leaves, and +rubbish in fields and fence rows. Although the insect has wings, it +seldom or never uses them, usually traveling on foot; therefore a deep +furrow around the field to be protected will hinder or stop the progress +of an invasion. The bugs fall into the bottom of the furrow, and may +there be killed by dragging a log up and down the furrow. Write to the +Division of Entomology, Washington, for bulletins on the chinch bug. +Other methods of prevention are to be found in these bulletins. + +[Illustration: FIG. 165. A PLANT LOUSE COLONY] + +=The Plant Louse.= The plant louse is very small, but it multiplies with +very great rapidity. During the summer the young are born alive, and it +is only toward fall that eggs are laid. The individuals that hatch from +eggs are generally wingless females, and their young, born alive, are +both winged and wingless. The winged forms fly to other plants and start +new colonies. Plant lice mature in from eight to fourteen days. + +The plant louse gives off a sweetish fluid of which some ants are very +fond. You may often see the ants stroking these lice to induce them to +give off a freer flow of the "honey dew." This is really a method of +milking. However friendly and useful these "cows" may be to the ant, +they are enemies to man in destroying so many of his plants. + +_Treatment._ These are sucking insects. Poisons therefore do not avail. +They may be killed by spraying with kerosene emulsion or a strong soap +solution or with tobacco water. Lice on cabbages are easily killed by a +mixture of one pound of lye soap in four gallons of warm water. + +[Illustration: FIG. 166. A CHEAP SPRAYING OUTFIT] + +=The Squash Bug.= The squash bug does its greatest damage to young +plants. To such its attack is often fatal. On larger plants single +leaves may die. This insect is a serious enemy to a crop and is +particularly difficult to get rid of, since it belongs to the class of +sucking insects, not to the biting insects. For this reason poisons are +useless. + +[Illustration: FIG. 167. A SQUASH BUG] + +_Treatment._ About the only practicable remedy is to pick these insects +by hand. We can, however, protect our young plants by small nettings and +thus tide them over the most dangerous period of their lives. These bugs +greatly prefer the squash as food. You can therefore diminish their +attack on your melons, cucumbers, etc. by planting among the melons an +occasional squash plant as a "trap plant." Hand picking will be easier +on a few trap plants than over the whole field. A small board or large +leaf laid beside the young plant often furnishes night shelter for the +bugs. The bugs collected under the board may easily be killed every +morning. + +=The Flea-Beetle.= The flea-beetle inflicts much damage on the potato, +tomato, eggplant, and other garden plants. The accompanying figure shows +the common striped flea-beetle which lives on the tomato. The larva of +this beetle lives inside of the leaves, mining its way through the leaf +in a real tunnel. Any substance disagreeable to the beetle, such as +plaster, soot, ashes, or tobacco, will repel its attacks on the garden +crops. + +[Illustration: FIG. 168. FLEA-BEETLE AND LARVA +_a_, larva; _b_, adult. Lines on sides show real length of insects] + +=The Weevil.= The weevil is commonly found among seeds. Its attacks are +serious, but the insect may easily be destroyed. + +_Treatment._ Put the infected seeds in an air-tight box or bin, placing +on the top of the pile a dish containing carbon disulphide, a +tablespoonful to a bushel of seeds. The fumes of this substance are +heavy and will pass through the mass of seeds below and kill all the +weevils and other animals there. The bin should be closely covered with +canvas or heavy cloth to prevent the fumes from being carried away by +the air. Let the seeds remain thus from two to five days. Repeat the +treatment if any weevils are found alive. Fumigate when the temperature +is 70 deg. Fahrenheit or above. In cold weather or in a loose bin the +treatment is not successful. _Caution:_ Do not approach the bin with a +light, since the fumes of the chemical used are highly inflammable. + +=The Hessian Fly.= The Hessian fly does more damage to the wheat crop +than all other insects combined, and probably ranks next to the chinch +bug as the second worst insect enemy of the farmer. It was probably +introduced into this country by the Hessian troops in the War of the +Revolution. + +[Illustration: FIG. 169. THE HESSIAN FLY] + +In autumn the insect lays its eggs in the leaves of the wheat. These +hatch into the larvae, which move down into the crown of the plant, where +they pass the winter. There they cause on the plant a slight gall +formation, which injures or kills the plant. In the spring adult flies +emerge and lay eggs. The larvae that hatch feed in the lower joints of +the growing wheat and prevent its proper growth. These larvae pupate and +remain as pupae in the wheat stubble during the summer. The fall brood of +flies appears shortly before the first heavy frost. + +_Treatment._ Burn all stubble and trash during July and August. If the +fly is very bad, it is well to leave the stubble unusually high to +insure a rapid spread of the fire. Burn refuse from the +threshing-machine, since this often harbors many larvae or pupae. Follow +the burning by deep plowing, because the burning cannot reach the +insects that are in the base of the plants. Delay the fall planting +until time for heavy frosts. + +=The Potato Beetle; Tobacco Worm.= The potato beetle, tobacco worm, +etc., are too well known to need description. Suffice it to say that no +good farmer will neglect to protect his crop from any pest that +threatens it. + +The increase, owing to various causes, of insects, of fungi, of +bacterial diseases, makes a study of these pests, of their origin, and +of their prevention a necessary part of a successful farmer's training. +Tillage alone will no longer render orchard, vineyard, and garden +fruitful. Protection from every form of plant enemies must be added to +tillage. + +[Illustration: FIG. 170. SPRAYING THE ORCHARD +One way of increasing the yield of fruit] + +In dealing with plants, as with human beings, the great object should be +not the cure but the prevention of disease. If disease can be prevented, +it is far too costly to wait for it to develop and then to attempt its +cure. Men of science are studying the new forms of diseases and new +insects as fast as they appear. These men are finding ways of fighting +old and new enemies. Young people who expect to farm should early learn +to follow their advice. + + + =EXERCISE= + + How does the squash bug resemble the plant louse? Is this a true + bug? Gather some eggs and watch the development of the insects in a + breeding-cage. Estimate the damage done to some crops by the + flea-beetle. What is the best method of prevention? + + [Illustration: FIG. 171. AN APPLE TREE SHOWING PROPER CARE] + + Do you know the large moth that is the mother of the tobacco worm? + You may often see her visiting the blossoms of the Jimson weed. + Some tobacco-growers cultivate a few of these weeds in a tobacco + field. In the blossom they place a little cobalt or "fly-stone" and + sirup. When the tobacco-worm moth visits this flower and sips the + poisoned nectar, she will of course lay no more troublesome eggs. + + +SECTION XXXIV. THE COTTON-BOLL WEEVIL + +So far as known, the cotton-boll weevil, an insect which is a native of +the tropics, crossed the Rio Grande River into Texas in 1891 and 1892. +It settled in the cotton fields around Brownsville. Since then it has +widened its destructive area until now it has invaded the whole +territory shown by the map on page 177. + +[Illustration: FIG. 172. ADULT COTTON-BOLL WEEVIL +Enlarged] + +This weevil is a small gray or reddish-brown snout-beetle hardly over a +quarter of an inch in length. In proportion to its length it has a long +beak. It belongs to a family of beetles which breed in pods, in seeds, +and in stalks of plants. It is a greedy eater, but feeds only on the +cotton plant. + +The grown weevils try to outlive the cold of winter by hiding snugly +away under grass clumps, cotton-stalks, rubbish, or under the bark of +trees. Sometimes they go down into holes in the ground. A comfortable +shelter is often found in the forests near the cotton fields, especially +in the moss on the trees. The weevils can stand a good deal of cold, but +fortunately many are killed by winter weather. Moreover birds destroy +many; hence by spring the last year's crop is very greatly diminished. + +In the spring, generally about the time cotton begins to form "squares," +the weevils shake off their long winter sleep and enter the cotton +fields with appetites as sharp as razors. Then shortly the females begin +to lay eggs. At first these eggs are laid only in the squares, and +generally only one to the square. The young grub hatches from these eggs +in two or three days. The newly hatched grub eats the inside of the +square, and the square soon falls to the ground. Entire fields may at +times be seen without a single square on the plants. Of course no fruit +can be formed without squares. + +[Illustration: FIG. 173. EGGS AMONG THE ANTHERS OF A SQUARE AT THE +POINT INDICATED BY THE ARROW] + +[Illustration: FIG. 174. CROSS SECTION SHOWING ANTHERS OF A SQUARE +WITH EGG OF WEEVIL, AND SHOWING THE HOLE WHERE THE EGG WAS DEPOSITED +Greatly enlarged] + +In from one to two weeks the grub or larva becomes fully grown and, +without changing its home, is transformed into the pupa state. Then in +about a week more the pupae come out as adult weevils and attack the +bolls. They puncture them with their snouts and lay their eggs in the +bolls. The young grubs, this time hatching out in the boll, remain there +until grown, when they emerge through holes that they make. These holes +allow dampness to enter and destroy the bolls. This life-round continues +until cold weather drives the insects to their winter quarters. By that +time they have increased so rapidly that there is often one for every +boll in the field. + +[Illustration: FIG. 175. THE LARVA OF THE COTTON-BOLL WEEVIL +INJURING A SQUARE] + +This weevil is proving very hard to destroy. At present there seem but +few ways to fight it. One is to grow cotton that will mature too early +for the weevils to do it much harm. A second is to kill as many weevils +as possible by burning the homes that shelter them in winter. + +[Illustration: FIG. 176. PUPA OF COTTON-BOLL WEEVIL FROM ABOVE AND BELOW +Greatly enlarged] + +[Illustration: FIG. 177. THE PUPA OF THE COTTON-BOLL WEEVIL IN A SQUARE] + +The places best adapted for a winter home for the weevil are trash +piles, rubbish, driftwood, rotten wood, weeds, moss on trees, etc. A +further help, therefore, in destroying the weevil is to cut down and +burn all cotton-stalks as soon as the cotton is harvested. + +[Illustration: FIG. 178. A COTTON BOLL WITH FEEDING-HOLES OF WEEVIL, +AND BEARING THREE SPECIMENS OF THE INSECT] + +[Illustration: FIG. 179. THE MEXICAN COTTON-BOLL WEEVIL, +SHOWING STRUCTURE] + +This destroys countless numbers of larvae and pupae in the bolls and +greatly reduces the number of weevils. In addition, all cornstalks, all +trash, all large clumps of grass in neighboring fields, should be +burned, so as to destroy these winter homes of the weevil. Also avoid +planting cotton near trees. The bark, moss, and fallen leaves of the +tree furnish a winter shelter for the weevils. + +[Illustration: FIG. 180. A SERIES OF FULL GROWN WEEVILS, SHOWING +VARIATIONS IN SIZE] + +A third help in destroying the weevil is to rotate crops. If cotton does +not follow cotton, the weevil has nothing on which to feed the second +year. + +[Illustration: FIG. 181. MAP SHOWING DISTRIBUTION OF THE COTTON-BOLL +WEEVIL IN 1913] + +In adopting the first method mentioned the cotton growers have found +that by the careful selection of seed, by early planting, by a free use +of fertilizers containing phosphoric acid, and by frequent plowing, they +can mature a crop about thirty days earlier than they usually do. In +this way a good crop can be harvested before the weevils are ready to be +most destructive. + + + + +CHAPTER VIII + +FARM CROPS + + +Every crop of the farm has been changed and improved in many ways since +its forefathers were wild plants. Those plants that best serve the needs +of the farmer and of farm animals have undergone the most changes and +have received also the greatest care and attention in their production +and improvement. + +While we have many different kinds of farm crops, the cultivated soil of +the world is occupied by a very few. In our country the crop that is +most valuable and that occupies the greatest land area is generally +known as the _grass crop_. Included in the general term "grass crop" are +the grasses and clovers that are used for pasturage as well as for hay. +Next to grass in value come the great cereal, corn, and the most +important fiber crop, cotton, closely followed by the great bread crop, +wheat. Oats rank fifth in value, potatoes sixth, and tobacco seventh. +(These figures are for 1913.) + +Success in growing any crop is largely due to the suitableness of soil +and climate to that crop. When the planter selects both the most +suitable soil and the most suitable climate for each crop, he gets not +only the most bountiful yield from the crop but, in addition, he gets +the most desirable quality of product. A little careful observation and +study soon teach what kinds of soil produce crops of the highest +excellence. This learned, the planter is able to grow in each field the +several crops best adapted to that special type of soil. Thus we have +tobacco soils, trucking soils, wheat and corn soils. Dairying can be +most profitably followed in sections where crops like cowpeas, clover, +alfalfa, and corn are peculiarly at home. No one should try to grow a +new crop in his section until he has found out whether the crop which he +wants to grow is adapted to his soil and his climate. + +[Illustration: FIG. 182. ALFALFA IN THE STACK +This is the second cutting of the season] + +The figures below give the average amount of money made annually an acre +on our chief crops: + +Flowers and plants, $1911; nursery products, $261; onions, $140; sugar +cane, $55; small fruits, $110; hops, $175; vegetables, $78; tobacco, +$80; sweet potatoes, $55; hemp, $53; potatoes, $78; sugar beets, $54; +sorghum cane, $22; cotton, $22; orchard fruits, $110; peanuts, $21; +flax-seed, $14; cereals, $14; hay and forage, $11; castor beans, $6 +(United States Census Report). + + +SECTION XXXV. COTTON + +Although cotton was cultivated on the Eastern continent before America +was discovered, this crop owes its present kingly place in the business +world to the zeal and intelligence of its American growers. So great an +influence does it wield in modern industrial life that it is often +called King Cotton. Thousands upon thousands of people scan the +newspapers each day to see what price its staple is bringing. From its +bounty a vast army of toilers, who plant its seed, who pick its bolls, +who gin its staple, who spin and weave its lint, who grind its seed, who +refine its oil, draw daily bread. Does not its proper production deserve +the best thought that can be given it? + +In the cotton belt almost any well-drained soil will produce cotton. The +following kinds of soil are admirably suited to this plant: red and gray +loams with good clay subsoil; sandy soils over clay and sandstone and +limestone; rich, well-drained bottom-lands. The safest soils are medium +loams. Cotton land must always be well drained. + +Cotton was originally a tropical plant, but, strange to say, it seems to +thrive best in temperate zones. The cotton plant does best, according to +Newman, in climates which have (1) six months of freedom from frost; (2) +a moderate, well-distributed rainfall during the plant's growing period; +and (3) abundant sunshine and little rain during the plant's maturing +period. + +[Illustration: FIG. 183. GROWTH OF COTTON FROM DAY TO DAY + +In America the Southern states from Virginia to Texas have these +climatic qualities, and it is in these states that the cotton industry +has been developed until it is one of the giant industries of the world. +This development has been very rapid. As late as 1736 the cotton plant +was grown as an ornamental flowering plant in many front yards; in +1911, 16,250,276 bales of cotton were grown in the South. In recent +years the soil and climate of lower California and parts of Arizona and +New Mexico have been found well adapted to cotton. + +[Illustration: FIG. 184. COTTON IN THE GROWING SEASON] + +There are a great many varieties of cotton. Two types are mainly grown +by the practical American farmer. These are the short-stapled, upland +variety most commonly grown in all the Southern states, and the +beautiful, long-stapled, black-seeded sea-island type that grows upon +the islands and a portion of the mainland of Georgia, South Carolina, +and Florida. The air of the coast seems necessary for the production of +this latter variety. The seeds of the sea-island cotton are small, +smooth, and black. They are so smooth and stick so loosely to the lint +that they are separated from it by roller-gins instead of by saw-gins. +When these seeds are planted away from the soil and air of their ocean +home, the plant does not thrive. + +Many attempts have been made and are still being made to increase the +length of the staple of the upland types. The methods used are as +follows: selection of seed having a long fiber; special cultivation and +fertilization; crossing the short-stapled cotton on the long-stapled +cotton. This last process, as already explained, is called +_hybridizing_. Many of these attempts have succeeded, and there are now +a large number of varieties which excel the older varieties in +profitable yield. The new varieties are each year being more widely +grown. Every farmer should study the new types and select the one that +will best suit his land. The new types have been developed under the +best tillage. Therefore if a farmer would keep the new type as good as +it was when he began to grow it, he must give it the same good tillage, +and practice seed-selection. + +[Illustration: FIG. 185. COTTON READY FOR PICKING] + +The cotton plant is nourished by a tap-root that will seek food as +deeply as loose earth will permit the root to penetrate; hence, in +preparing land for this crop the first plowing should be done at least +with a two-horse plow and should be deep and thorough. This deep plowing +not only allows the tap-root to penetrate, but it also admits a +circulation of air. + +On some cotton farms it is the practice to break the land in winter or +early spring and then let it lie naked until planting-time. This is not +a good practice. The winter rains wash more plant food out of +unprotected soil than a single crop would use. It would be better, in +the late summer or fall, to plant crimson clover or some other +protective and enriching crop on land that is to be planted in cotton in +the spring. This crop, in addition to keeping the land from being +injuriously washed, would greatly help the coming cotton crop by leaving +the soil full of vegetable matter. + +In preparing for cotton-planting, first disk the land thoroughly, then +break with a heavy plow and harrow until a fine and mellow seed-bed is +formed. Do not spare the harrow at this time. It destroys many a weed +that, if allowed to grow, would have to be cut by costly hoeing. +Thorough work before planting saves much expensive work in the later +days of the crop. Moreover, no man can afford to allow his plant food +and moisture to go to nourish weeds, even for a short time. + +The rows should be from three to four feet apart. The width depends upon +the richness of the soil. On rich land the rows should be at least four +feet apart. This width allows the luxuriant plant to branch and fruit +well. On poorer lands the distance of the rows should not be so great. +The distribution of the seed in the row is of course most cheaply done +by the planter. As a rule it is best not to ridge the land for the seed. +Flat culture saves moisture and often prevents damage to the roots. In +some sections, however, where the land is flat and full of water, +ridging seems necessary if the land cannot be drained. + +[Illustration: FIG. 186. PICKING COTTON] + +The cheapest way of cultivating a crop is to prevent grass and weeds +from rooting, not to wait to destroy them after they are well rooted. To +do this, it is well to run the two-horse smoothing-harrow over the +land, across the rows, a few days after the young plants are up. Repeat +the harrowing in six or eight days. In addition to destroying the young +grass and weeds, this harrowing also removes many of the young cotton +plants and thereby saves much hoeing at "chopping-out" time. When the +plants are about two inches high they are "chopped out" to secure an +evenly distributed stand. It has been the custom to leave two stalks to +a hill, but many growers are now leaving only one. + +The number of times the crop has to be worked depends on the soil and +the season. If the soil is dry and porous, cultivate as often as +possible, especially after each rain. Never allow a crust to form after +a rain; the roots of plants must have air. Cultivation after each rain +forms a dry mulch on the top of the soil and thus prevents rapid +evaporation of moisture. + +If the fiber (the lint) only is removed from the land on which cotton is +grown, cotton is the least exhaustive of the great crops grown in the +United States. According to some recent experiments an average crop of +cotton removes in the lint only 2.75 pounds of nitrogen, phosphoric +acid, potash, lime, and magnesia per acre, while a crop of ten bushels +of wheat per acre removes 32.36 pounds of the same elements of plant +food. Inasmuch as this crop takes so little plant food from the soil, +the cotton-farmer has no excuse for allowing his land to decrease in +productiveness. Two things will keep his land in bounteous harvest +condition: first, let him return the seeds in some form to the land, or, +what is better, feed the ground seeds to cattle, make a profit from the +cattle, and return manure to the land in place of the seeds; second, at +the last working, let him sow some crop like crimson clover or rye in +the cotton rows to protect the soil during the winter and to leave humus +in the ground for the spring. + +The stable manure, if that is used, should be broadcasted over the +fields at the rate of six to ten tons an acre. If commercial fertilizers +are used, it may be best to make two applications. To give the young +plants a good start, apply a portion of the fertilizer in the drill just +before planting. Then when the first blooms appear, put the remainder of +the fertilizer in drills near the plants but not too close. Many good +cotton-growers, however, apply all the fertilizer at one time. + +[Illustration: FIG. 187. WEIGHING A DAY'S PICKING OF COTTON] + +_Relation of Stock to the Cotton Crop_. On many farms much of the money +for which the cotton is sold in the fall has to go to pay for the +commercial fertilizer used in growing the crop. Should not this fact +suggest efforts to raise just as good crops without having to buy so +much fertilizer? Is there any way by which this can be done? The +following suggestions may be helpful. Raise enough stock to use all the +cotton seed grown on the farm. To go with the food made from the cotton +seed, grow on the farm pea-vine hay, clover, alfalfa, and other such +nitrogen-gathering crops. This can be done at small cost. What will be +the result? + +First, to say nothing of the money made from the cattle, the large +quantity of stable manure saved will largely reduce the amount of +commercial fertilizer needed. The cotton-farmer cannot afford to neglect +cattle-raising. The cattle sections of the country are likely to make +the greatest progress in agriculture, because they have manure always on +hand. + +[Illustration: FIG. 188. MODERN COTTON BALES] + +Second, the nitrogen-gathering crops, while helping to feed the stock, +also reduce the fertilizer bills by supplying one of the costly elements +of the fertilizer. The ordinary cotton fertilizer consists principally +of nitrogen, of potash, and of phosphoric acid. Of these three, by far +the most costly is nitrogen. Now peas, beans, clover, and peanuts will +leave enough nitrogen in the soil for cotton, so that if they are +raised, it is necessary to buy only phosphoric acid and sometimes +potash. + + +SECTION XXXVI. TOBACCO + +The tobacco plant connects Indian agriculture with our own. It has +always been a source of great profit to our people. In the early +colonial days tobacco was almost the only money crop. Many rich men came +to America in those days merely to raise tobacco. + +Although tobacco will grow in almost any climate, the leaves, which, as +most of you know, are the salable part of the plant, get their desirable +or undesirable qualities very largely from the soil and from the climate +in which they grow. + +The soil in which tobacco thrives best is one which has the following +qualities: dryness, warmth, richness, depth, and sandiness. + +Commercial fertilizers also are almost a necessity; for, as tobacco land +is limited in area, the same land must be often planted in tobacco. +Hence even a fresh, rich soil that did not at first require fertilizing +soon becomes exhausted, and, after the land has been robbed of its plant +food by crop after crop of tobacco, frequent application of fertilizers +and other manures becomes necessary. However, even tobacco growers +should rotate their crops as much as possible. + +[Illustration: FIG. 189. A LEAF OF TOBACCO] + +Deep plowing--from nine to thirteen inches--is also a necessity in +preparing the land, for tobacco roots go deep into the soil. After this +deep plowing, harrow until the soil is thoroughly pulverized and is as +fine and mellow as that of the flower-garden. + +Unlike most other farm crops the tobacco plant must be started first in +a seed-bed. To prepare a tobacco bed the almost universal custom has +been to proceed as follows. Carefully select a protected spot. Over this +spot pile brushwood and then burn it. The soil will be left dry, and all +the weed seeds will be killed. The bed is then carefully raked and +smoothed and planted. Some farmers are now preparing their beds without +burning. A tablespoonful of seed will sow a patch twenty-five feet +square. A cheap cloth cover is put over the bed. If the seeds come up +well, a patch of this size ought to furnish transplants for five or six +acres. In sowing, it is not wise to cover the seed deeply. A light +raking in or an even rolling of the ground is all that is needed. + +[Illustration: FIG. 190. A PROMISING CROP OF TOBACCO] + +The time required for sprouting is from two to three weeks. The plants +ought to be ready for transplanting in from four to six weeks. Weeds +and grass should of course be kept out of the seed-bed. + +The plants, when ready, are transplanted in very much the same way as +cabbages and tomatoes. The transplanting was formerly done by hand, but +an effective machine is now widely used. The rows should be from three +to three and a half feet apart, and the plants in the rows about two or +three feet apart. If the plants are set so that the plow and cultivator +can be run with the rows and also across the rows, they can be more +economically worked. Tobacco, like corn, requires shallow cultivation. +Of course the plants should be worked often enough to give clean culture +and to provide a soil mulch for saving moisture. + +[Illustration: FIG. 191. TOPPING TOBACCO] + +In tobacco culture it is necessary to pinch off the "buttons" and to cut +off the tops of the main stalk, else much nourishment that should go to +the leaves will be given to the seeds. The suckers must also be cut off +for the same reason. + +The proper time for harvesting is not easily fixed; one becomes skillful +in this work only through experience in the field. Briefly, we may say +that tobacco is ready to be cut when the leaves on being held up to the +sun show a light or golden color, when they are sticky to the touch, and +when they break easily on being bent. Plants that are overripe are +inferior to those that are cut early. + +The operations included in cutting, housing, drying, shipping, sweating, +and packing require skill and practice. + + +SECTION XXXVII. WHEAT + +Wheat has been cultivated from earliest times. It was a chief crop in +Egypt and Palestine, and still holds its importance in the temperate +portions of Europe, Asia, Africa, Australia, and America. + +[Illustration: FIG. 192. A HAND] + +[Illustration: FIG. 193. WHEAT HEADS] + +This crop ranks third in value in the United States. It grows in cool, +in temperate, and in warm climates, and in many kinds of soil. It does +best in clay loam, and worst in sandy soils. Clogged and water-soaked +land will not grow wheat with profit to the farmer; for this reason, +where good wheat-production is desired the soil must be well drained +and in good physical condition--that is, the soil must be open, crumbly, +and mellow. + +Clay soils that are hard and lifeless can be made valuable for +wheat-production by covering the surface with manure, by good tillage, +and by a thorough system of crop-rotation. Cowpeas and other legumes +make a most valuable crop to precede wheat, for in growing they add +atmospheric nitrogen to the soil, and their roots loosen the root-bed, +thereby admitting a free circulation of air and adding humus to the +soil. Moreover, the legumes leave the soil with its grains fairly close +packed, and this is a help in wheat growing. + +One may secure a good seed-bed after cotton and corn as well as after +cowpeas and other legumes. They are summer-cultivated crops, and the +clean culture that has been given them renders the surface soil mellow +and the undersoil firm and compact. They are not so good, however, as +cowpeas, since they add no atmospheric nitrogen to the soil, as all +leguminous crops do. + +[Illustration: FIG. 194. ROOTS OF A SINGLE WHEAT PLANT] + +From one to two inches is the most satisfactory depth for planting +wheat. The largest number of seeds comes up when planted at this depth. +A mellow soil is very helpful to good coming up and provides a most +comfortable home for the roots of the plant. A compact soil below makes +a moist undersoil; and this is desirable, for the soil water is needed +to dissolve plant food and to carry it up through the plant, where it is +used in building tissue. + +There are a great many varieties of wheat: some are bearded, others are +smooth; some are winter and others are spring varieties. The +smooth-headed varieties are most agreeable to handle during harvest and +at threshing-time. Some of the bearded varieties, however, do so well in +some soils and climates that it is desirable to continue growing them, +though they are less agreeable to handle. No matter what variety you are +accustomed to raise, it may be improved by careful seed-selection. + +[Illustration: FIG. 195. SELECTING WHEAT SEED] + +The seed-drill is the best implement for planting wheat. It distributes +the grains evenly over the whole field and leaves the mellow soil in a +condition to catch what snow may fall and secure what protection it +affords. + +[Illustration: FIG. 196. ADJOINING WHEAT FIELDS +The yield of the lower field, forty-five bushels per acre, is due to +intelligent farming] + +In many parts of the country, because not enough live stock is raised, +there is often too little manure to apply to the wheat land. Where this +is the case commercial fertilizers must be used. Since soils differ +greatly, it is impossible to suggest a fertilizer adapted to all soils. +The elements usually lacking in wheat soils are nitrogen, phosphoric +acid, and potash. The land may be lacking in one of these plant foods or +in all; in either case a maximum crop cannot possibly be raised. The +section on manuring the soil will be helpful to the wheat-grower. + +[Illustration: FIG. 197. A BOUNTIFUL CROP OF WHEAT] + +It should be remembered always in buying fertilizers for wheat that +whenever wheat follows cowpeas or clover or other legumes there is +seldom need of using nitrogen in the fertilizer; the tubercles on the +pea or clover roots will furnish that. Hence, as a rule, only potash and +phosphoric acid will have to be purchased as plant food. + +The farmer is assisted always by a study of his crop and by a knowledge +of how it grows. If he find the straw inferior and short, it means that +the soil is deficient in nitrogen; but on the other hand, if the straw +be luxuriant and the heads small and poorly filled, he may be sure that +his soil contains too little phosphoric acid and potash. + + + =EXERCISE= + + Let the pupils secure several heads of wheat and thresh each + separately by hand. The grains should then be counted and their + plumpness and size observed. The practical importance of this is + obvious, for the larger the heads and the greater the number of + grains, the larger the yield per acre. Let them plant some of the + large and some of the small grains. A single test of this kind will + show the importance of careful seed-selection. + +[Illustration: FIG. 198 A WIDELY GROWN CROP] + + +SECTION XXXVIII. CORN + +When the white man came to this country he found the Indians using corn; +for this reason, in addition to its name _maize_, it is called _Indian +corn_. Before that time the civilized world did not know that there was +such a crop. The increase in the yield and the extension of the acres +planted in this strictly American crop have kept pace with the rapid +and wonderful growth of our country. Corn is king of the cereals and the +most important crop of American agriculture. It grows in almost every +section of America. There is hardly any limit to the uses to which its +grain and its stalks are now put. Animals of many kinds are fed on +rations into which it enters. Its grains in some form furnish food to +more people than does any other crop except possibly rice. Its stalk and +its cob are manufactured into many different and useful articles. + +A soil rich in either decaying animal or vegetable matter, loose, warm, +and moist but not wet, will produce a better crop of corn than any +other. Corn soil should always be well tilled and cultivated. + +The proper time to begin the cultivation of corn is before it is +planted. Plow well. A shallow, worn-out soil should not be used for +corn, but for cowpeas or rye. After thorough plowing, the harrow--either +the disk or spring-tooth--should be used to destroy all clods and leave +the surface mellow and fine. The best results will be obtained by +turning under a clover sod that has been manured from the savings of the +barnyard. + +When manure is not available, commercial fertilizers will often prove +profitable on poor lands. Careful trials will best determine how much +fertilizer to an acre is necessary, and what kinds are to be used. A +little study and experimenting on the farmer's part will soon enable him +to find out both the kind and the amount of fertilizer that is best +suited to his land. + +The seed for this crop should be selected according to the plan +suggested in Section XIX. + +[Illustration: FIG. 199. CORN SHOCKED FOR THE SHREDDER] + +The most economical method of planting is by means of the horse planter, +which, according to its adjustment, plants regularly in hills or in +drills. A few days after planting, the cornfield should be harrowed with +a fine-tooth harrow to loosen the top soil and to kill the grass and the +weed seeds that are germinating at the surface. When the corn plants +are from a half inch to an inch high, the harrow may again be used. A +little work before the weeds sprout will save many days of labor during +the rest of the season, and increase the yield. + +[Illustration: FIG. 200. THE DIFFERENCE IS DUE TO TILLAGE] + +Corn is a crop that needs constant cultivation, and during the growing +season the soil should be stirred at least four times. This cultivation +is for three reasons: + +1. To destroy weeds that would take plant food and water. + +2. To provide a mulch of dry soil so as to prevent the evaporation of +moisture. The action of this mulch has already been explained. + +3. Because "tillage is manure." Constant stirring of the soil allows the +air to circulate in it, provides a more effective mulch, and helps to +change unavailable plant food into the form that plants use. + +Deep culture of corn is not advisable. The roots in their early stages +of growth are shallow feeders and spread widely only a few inches below +the surface. The cultivation that destroys or disturbs the roots injures +the plants and lessens the yield. We cultivate because of the three +reasons given above, and not to stir the soil about the roots or to +loosen it there. + +[Illustration: FIG. 201.] + +In many parts of the country the cornstalks are left standing in the +fields or are burned. This is a great mistake, for the stalks are worth +a good deal for feeding horses, cattle, and sheep. These stalks may +always be saved by the use of the husker and shredder. Corn after being +matured and cut can be put in shocks and left thus until dry enough to +run through the husker and shredder. This machine separates the corn +from the stalk and husks it. At the same time it shreds tops, leaves, +and butts into a food that is both nutritious and palatable to stock. +For the amount that animals will eat, almost as much feeding value is +obtained from corn stover treated in this way as from timothy hay. The +practice of not using the stalks is wasteful and is fast being +abandoned. The only reason that so much good food is being left to decay +in the field is because so many people have not fully learned the +feeding value of the stover. + + + =EXERCISE= + + To show the effect of cultivation on the yield of corn, let the + pupils lay off five plats in some convenient field. Each plat need + consist of only two rows about twenty feet long. Treat each plat as + follows: + + Plat 1. No cultivation: let weeds grow. + + Plat 2. Mulch with straw. + + Plat 3. Shallow cultivation: not deeper than two inches and at + least five times during the growing season. + + Plat 4. Deep cultivation: at least four inches deep, so as to + injure and tear out some of the roots (this is a common method). + + Plat 5. Root-pruning: ten inches from the stalk and six inches + deep, prune the roots with a long knife. Cultivate five times + during the season. + + Observe plats during the summer, and at husking-time note results. + + +SECTION XXXIX. PEANUTS + +This plant is rich in names, being known locally as "ground pea," +"goober," "earthnut," and "pindar," as well as generally by the name of +"peanut." The peanut is a true legume, and, like other legumes, bears +nitrogen-gathering tubercles upon its roots. The fruit is not a real nut +but rather a kind of pea or bean, and develops from the blossom. After +the fall of the blossom the "spike," or flower-stalk, pushes its way +into the ground, where the nut develops. If unable to penetrate the soil +the nut dies. + +In the United States, North and South Carolina, Virginia, and Tennessee +have the most favorable climates for peanut culture. Suitable climate +and soil, however, may be found from New Jersey to the Mississippi +valley. A high, porous, sandy loam is the most suitable. Stiffer soils, +which may in some cases yield larger crops than the loams, are yet not +so profitable, for stiff soils injure the color of the nut. Lime is a +necessity and must be supplied if the soil is deficient. Phosphoric acid +and potash are needed. + +Greater care than is usually bestowed should be given to the selection +of the peanut seed. In addition to following the principles given in +Section XVIII, all musty, defective seeds must be avoided and all +frosted kernels must be rejected. Before it dries, the peanut seed is +easily injured by frost. The slightest frost on the vines, either before +or after the plants are dug, does much harm to the tender seed. + +[Illustration: FIG. 202. A PEANUT PLANT] + +In growing peanuts, thorough preparation of the soil is much better than +later cultivation. Destroy the crop of young weeds, but do not disturb +the peanut crop by late cultivation. Harvest before frost, and shock +high to keep the vines from the ground. + +The average yield of peanuts in the United States is twenty-two bushels +an acre. In Tennessee the yield is twenty-nine bushels an acre, and in +North Carolina and Virginia it reaches thirty bushels an acre. + + +SECTION XL. SWEET POTATOES + +The roots of sweet potatoes are put on the market in various forms. +Aside from the form in which they are ordinarily sold, some potatoes are +dried and then ground into flour, some are canned, some are used to make +starch, some furnish a kind of sugar called glucose, and some are even +used to make alcohol. + +The fact that there are over eighty varieties of potatoes shows the +popularity of the plant. Now it is evident that all of these varieties +cannot be equally desirable. Hence the wise grower will select his +varieties with prudent forethought. He should study his market, his +soil, and his seed (see Section XVIII). + +[Illustration: FIG. 203. SWEET POTATOES] + +Four months of mild weather, months free from frost and cold winds, are +necessary for the growing of sweet potatoes. In a mild climate almost +any loose, well-drained soil will produce them. A light, sandy loam, +however, gives a cleaner potato and one, therefore, that sells better. + +The sweet potato draws potash, nitrogen, and phosphoric acid from the +soil, but in applying these as fertilizers the grower must study and +know his own soil. If he does not he may waste both money and plant food +by the addition of elements already present in sufficient quantity in +the soil. The only way to come to reliable conclusions as to the needs +of the soil is to try two or three different kinds of fertilizers on +plats of the same soil, during the same season, and notice the resulting +crop of potatoes. + +Sweet potatoes will do well after almost any of the usual field crops. +This caution, however, should be borne in mind. Potatoes should not +follow a sod. This is because sods are often thick with cutworms, one of +the serious enemies of the potato. + +It is needless to say that the ground must be kept clean by thorough +cultivation until the vines take full possession of the field. + +In harvesting, extreme care should be used to avoid cutting and bruising +the potato, since bruises are as dangerous to a sweet potato as to an +apple, and render decay almost a certainty. Lay aside all bruised +potatoes for immediate use. + +For shipment the potatoes should be graded and packed with care. An +extra outlay of fifty cents a barrel often brings a return of a dollar a +barrel in the market. One fact often neglected by Southern growers who +raise potatoes for a Northern market is that the Northern markets demand +a potato that will cook dry and mealy, and that they will not accept the +juicy, sugary potato so popular in the South. + +The storage of sweet potatoes presents difficulties owing to their great +tendency to decay under the influence of the ever-present fungi and +bacteria. This tendency can be met by preventing bruises and by keeping +the bin free from rotting potatoes. The potatoes should be cleaned, and +after the moisture has been dried off they should be stored in a dry, +warm place. + +The sweet-potato vine makes a fair quality of hay and with proper +precaution may be used for ensilage. Small, defective, unsalable +potatoes are rich in sugar and starch and are therefore good stock food. +Since they contain so much water they must be used only as an aid to +other diet. + + +SECTION XLI. WHITE, OR IRISH, POTATOES + +Maize, or Indian corn, and potatoes are the two greatest gifts in the +way of food that America has bestowed on the other nations. Since their +adoption in the sixteenth century as a new food from recently discovered +America, white potatoes have become one of the world's most important +crops. + +[Illustration: FIG. 204. CULTIVATING AND RIDGING POTATOES] + +No grower will harvest large crops of potatoes unless he chooses soil +that suits the plant, selects his seed carefully, cultivates thoroughly, +feeds his land sufficiently, and sprays regularly. + +The soil should be free from potato scab. This disease remains in land +for several years. Hence if land is known to have any form of scab in +it, do not plant potatoes in such land. Select for this crop a deep and +moderately light, sandy loam which has an open subsoil and which is rich +in humus. The soil must be light enough for the potatoes, or tubers, to +enlarge easily and dry enough to prevent rot or blight or other +diseases. Potato soil should be so close-grained that it will hold +moisture during a dry spell and yet so well-drained that the tubers will +not be hurt by too much moisture in wet weather. + +If the land selected for potatoes is lacking in humus, fine compost or +well-rotted manure will greatly increase the yield. However, it should +be remembered that green manure makes a good home for the growth of scab +germs. Hence it is safest to apply this sort of manure in the fall, or, +better still, use a heavy dressing of manure on the crop which the +potatoes are to follow. Leguminous crops supply both humus and nitrogen +and, at the same time, improve the subsoil. Therefore such crops are +excellent to go immediately before potatoes. If land is well supplied +with humus, commercial fertilizers are perhaps safer than manure, for +when these fertilizers are used the amount of plant food is more easily +regulated. Select a fertilizer that is rich in potash. For gardens +unleached wood ashes make a valuable fertilizer because they supply +potash. Early potatoes need more fertilization than do late ones. While +potatoes do best on rich land, they should not be overfed, for a too +heavy growth of foliage is likely to cause blight. + +Be careful to select seed from sound potatoes which are entirely free +from scab. Get the kinds that thrive best in the section in which they +are to be planted and which suit best the markets in which they are to +be sold. Seed potatoes should be kept in a cool place so that they will +not sprout before planting-time. As a rule consumers prefer a smooth, +regularly shaped, shallow-eyed white or flesh-colored potato which is +mealy when cooked. Therefore, select seed tubers with these qualities. +It seems proved that when whole potatoes are used for seed the yield is +larger than when sliced potatoes are planted. It is of course too +costly to plant whole potatoes, but it is a good practice to cause the +plants to thrive by planting large seed pieces. + +[Illustration: FIG. 205. GATHERING POTATOES] + +Like other crops, potatoes need a thoroughly prepared seed-bed and +intelligent cultivation. Break the land deep. Then go over it with an +ordinary harrow until all clods are broken and the soil is fine and well +closed. The rows should be at least three feet from one another and the +seeds placed from twelve to eighteen inches apart in the row, and +covered to a depth of three or four inches. A late crop should be +planted deeper than an early one. Before the plants come up it is well +to go over the field once or twice with a harrow so as to kill all +weeds. Do not fail to save moisture by frequent cultivation. After the +plants start to grow, all cultivation should be shallow, for the roots +feed near the surface and should not be broken. Cultivate as often as +needed to keep down weeds and grass and to keep the ground fine. + +Allow potatoes to dry thoroughly before they are stored, but never allow +them to remain long in the sunshine. Never dig them in damp weather, for +the moisture clinging to them will cause them to rot. After the tubers +are dry, store them in barrels or bins in a dry, cool, and dark place. +Never allow them to freeze. + +Among the common diseases and insect pests that attack the leaves and +stems of potato vines are early blight, late blight, brown rot, the +flea-beetle, and the potato beetle, or potato bug. Spraying with +Bordeaux mixture to which a small portion of Paris green has been added +will control both the diseases and the pests. The spraying should begin +when the plants are five or six inches high and should not cease until +the foliage begins to die. + +Scab is a disease of the tubers. It may be prevented (1) by using seed +potatoes that are free from scab; (2) by planting land in which there is +no scab; and (3) by soaking the seed in formalin (see page 135). + + +SECTION XLII. OATS + +The oat plant belongs to the grass family. It is a hardy plant and, +under good conditions, a vigorous grower. It stands cold and wet better +than any other cereal except possibly rye. Oats like a cool, moist +climate. In warm climates, oats do best when they are sowed in the fall. +In cooler sections, spring seeding is more generally practiced. + +There are a great many varieties of oats. No one variety is best adapted +to all sections, but many varieties make fine crops in many sections. +Any variety is desirable which has these qualities: power to resist +disease and insect enemies, heavy grains, thin hulls, good color, and +suitability to local surroundings. + +As oats and rye make a better yield on poor land than any other cereals, +some farmers usually plant these crops on their poorest lands. However, +no land is too good to be used for so valuable a crop as oats. Oats +require a great deal of moisture; hence light, sandy soils are not so +well adapted to this crop as are the sandy loams and fine clay loams +with their closer and heavier texture. + +If oats are to be planted in the spring, the ground should be broken in +the fall, winter, or early spring so that no delay may occur at +seeding-time. But to have a thoroughly settled, compact seed-bed the +breaking of the land should be done at least a month before the seeding, +and it will help greatly to run over the land with a disk harrow +immediately after the breaking. + +[Illustration: FIG. 206. OATS +Common oats at left; side oats at right] + +Oats may be planted by scattering them broadcast or by means of a drill. +The drill is better, because the grains are more uniformly distributed +and the depth of planting is better regulated. The seeds should be +covered from one and a half to two inches deep. In a very dry season +three inches may not be too deep. The amount of seed needed to the acre +varies considerably, but generally the seeding is from two to three +bushels an acre. On poor lands two bushels will be a fair average +seeding; on good lands as much as three bushels should be used. + +[Illustration: FIG. 207. HARVESTING OATS] + +This crop fits in well, over wide areas, with various rotations. As the +purpose of all rotation is to keep the soil productive, oats should +alternate every few years with one of the nitrogen-gathering crops. In +the South, cowpeas, soy beans, clovers, and vetches may be used in this +rotation. In the North and West the clovers mixed with timothy hay make +a useful combination for this purpose. + +Spring-sowed oats, since they have a short growing season, need their +nitrogenous plant food in a form which can be quickly used. To supply +this nitrogen a top-dressing of nitrate of soda or sulphate of lime is +helpful. The plant can gather its food quickly from either of these +two. As fall-sowed oats have of course a longer growing season, the +nitrogen can be supplied by well-rotted manure, blood, tankage, or +fish-scrap. Use barnyard manure carefully. Do not apply too much just +before seeding, and use only thoroughly rotted manure. It is always +desirable to have a bountiful supply of humus in land on which oats are +to be planted. + +The time of harvesting will vary with the use which is to be made of the +oats. If the crop is to be threshed, the harvesting should be done when +the kernels have passed out of the milk into the hard dough state. The +lower leaves of the stalks will at this time have turned yellow, and the +kernels will be plump and full. Do not, however, wait too long, for if +you do the grain will shatter and the straw lose in feeding value. + +On the other hand, if the oats are to be cut for hay it is best to cut +them while the grains are still in the milk stage. At this stage the +leaves are still green and the plants are rich in protein. + +Oats should be cured quickly. It is very important that threshed oats +should be dry before they are stored. Should they on being stored still +contain moisture, they will be likely to heat and to discolor. Any +discoloring will reduce their value. Nor should oats ever be allowed to +remain long in the fields, no matter how well they may seem to be +shocked. The dew and the rain will injure their value by discoloring +them more or less. + +Oats are muscle-builders rather than fat-formers. Hence they are a +valuable ration for work animals, dairy cows, and breeding-stock. + + +SECTION XLIII. RYE + +Rye has the power of gathering its food from a wider area than most +other plants. Of course, then, it is a fine crop for poor land, and +farmers often plant it only on worn land. However, it is too good a +cereal to be treated in so ungenerous a fashion. As a cover-crop for +poor land it adds much humus to the soil and makes capital grazing. + +[Illustration: FIG. 208. RYE READY FOR CUTTING] + +There are two types of rye--the winter and the spring. The winter type +is chiefly grown in this country. Rye seeds should be bought as near +home as possible, for this plant thrives best when the new crop grows +under the same conditions as the seed crop. + +Rye will grow on almost any soil that is drained. Soils that are too +sandy for wheat will generally yield good crops of rye. Clay soils, +however, are not adapted to the plant nor to the grazing for which the +plant is generally sowed. For winter rye the land should be broken from +four to six inches. Harrows should follow the plows until the land is +well pulverized. In some cold prairie lands, however, rye is put in with +a grain-drill before a plow removes the stubble from the land. The +purpose of planting in this way is to let the stubble protect the young +plants from cold, driving winds. + +Rye should go into the ground earlier than wheat. In cold, bleak +climates, as well as on poor land, the seeding should be early. The +young plant needs to get rooted and topped before cold weather sets in. +The only danger in very early planting is that leaf-rust sometimes +attacks the forward crop. Of course the earlier the rye is ready for +fall and winter pasturage, the better. If a drill is used for planting, +a seeding of from three to four pecks to the acre should give a good +stand. In case the seeds are to be sowed broadcast, a bushel or a bushel +and a half for every acre is needed. The seed should be covered as wheat +seed is and the ground rolled. + +Rye is generally used as a grazing or as a soiling crop. Therefore its +value will depend largely on its vigorous growth in stems and leaves. To +get this growth, liberal amounts of nitrogenous fertilizer will have to +be applied unless the land is very rich. Put barnyard manure on the land +just after the first breaking and disk the manure into the soil. Acid +phosphate and kainite added to the manure may pay handsomely. A spring +top-dressing of nitrate of soda is usually helpful. + +Rye has a stiff straw and does not fall, or "lodge," so badly as some of +the other cereals. As soon as rye that is meant for threshing is cut, it +should be put up in shocks until it is thoroughly dry. Begin the cutting +when the kernels are in a tough dough state. The grain should never +stand long in the shocks. + + +SECTION XLIV. BARLEY + +Barley is one of the oldest crops known to man. The old historian Pliny +says that barley was the first food of mankind. Modern man however +prefers wheat and corn and potatoes to barley, and as a food this +ancient crop is in America turned over to the lower animals. Brewers use +barley extensively in making malt liquors. Barley grows in nearly all +sections of our country, but a few states--namely, Minnesota, +California, Wisconsin, Iowa, and North and South Dakota--are seeding +large areas to this crop. + +For malting purposes the barley raised on rather light, friable, porous +soil is best. Soils of this kind are likely to produce a medium yield of +bright grain. Fertile loamy and clay soils make generally a heavier +yield of barley, but the grain is dark and fit only to be fed to stock. +Barley is a shallow feeder, and can reach only such plant food as is +found in the top soil, so its food should always be put within reach by +a thorough breaking, harrowing, and mellowing of the soil, and by +fertilizing if the soil is poor. Barley has been successfully raised +both by irrigation and by dry-farming methods. It requires a +better-prepared soil than the other grain crops; it makes fine yields +when it follows some crop that has received a heavy dressing of manure. +Capital yields are produced after alfalfa or after root crops. This crop +usually matures within a hundred days from its seeding. + +[Illustration: FIG. 209. BARLEY] + +When the crop is to be sold to the brewers, a grain rich in starch +should be secured. Barley intended for malting should be fertilized to +this end. Many experiments have shown that a fertilizer which contains +much potash will produce starchy barley. If the barley be intended for +stock, you should breed so as to get protein in the grain and in the +stalk. Hence barley which is to be fed should be fertilized with +mixtures containing nitrogen and phosphoric acid. Young barley plants +are more likely to be hurt by cold than either wheat or oats. Hence +barley ought not to be seeded until all danger from frost is over. The +seeds should be covered deeper than the seeds of wheat or of oats. Four +inches is perhaps an average depth for covering. But the covering will +vary with the time of planting, with the kind of ground, with the +climate, and with the nature of the season. Fewer seeds will be needed +if the barley is planted by means of a drill. + +Like other cereals, barley should not be grown continuously on the same +land. It should take its place in a well-planned rotation. It may +profitably follow potatoes or other hoed crops, but it should not come +first after wheat, oats, or rye. + +Barley should be harvested as soon as most of its kernels have reached +the hard dough state. It is more likely to shatter its grain than are +other cereals, and it should therefore be handled with care. It must +also be watched to prevent its sprouting in the shocks. Be sure to put +few bundles in the shock and to cap the shock securely enough to keep +out dew and rain. If possible the barley should be threshed directly +from the shock, as much handling will occasion a serious loss from +shattering. + + +SECTION XLV. SUGAR PLANTS + +In the United States there are three sources from which sugar is +obtained; namely, the sugar-maple, the sugar-beet, and the sugar-cane. +In the early days of our country considerable quantities of maple sirup +and maple sugar were made. This was the first source of sugar. Then +sugar-cane began to be grown. Later the sugar-beet was introduced. + +=Maple Products.= In many states sirup and sugar are still made from +maple sap. In the spring when the sap is flowing freely maple trees are +tapped and spouts are inserted. Through these spouts the sap flows into +vessels set to catch it. The sap is boiled in evaporating-pans, and made +into either sirup or sugar. Four gallons of sap yield about one pound of +sugar. A single tree yields from two to six pounds of sugar in a season. +The sap cannot be kept long after it is collected. Practice and skill +are needed to produce an attractive and palatable grade of sirup or of +sugar. + +=Sugar-Beets.= The sugar-beet is a comparatively new root crop in +America. The amount of sugar that can be obtained from beets varies from +twelve to twenty per cent. The richness in sugar depends somewhat on the +variety grown and on the soil and the climate. + +So far most of our sugar-beet seeds have been brought over from Europe. +Some of our planters are now, however, gaining the skill and the +knowledge needed to grow these seeds. It is of course important to grow +seeds that will produce beets containing much sugar. + +[Illustration: FIG. 210. CATCHING MAPLE SAP] + +These beets do well in a great variety of soils if the land is rich, +well prepared, and well drained, and has a porous subsoil. + +Beets cannot grow to a large size in hard land. Hence deep plowing is +very necessary for this crop. The soil should be loose enough for the +whole body of the beet to remain underground. Some growers prefer spring +plowing and some fall plowing, but all agree that the land should not be +turned less than eight or ten inches. The subsoil, however, should not +be turned up too much at the first deep plowing. + +Too much care cannot be taken to make the seed-bed firm and mellow and +to have it free from clods. If the soil is dry at planting-time and +there is likelihood of high winds, the seed-bed may be rolled with +profit. Experienced growers use from ten to twelve pounds of seeds to an +acre. It is better to use too many rather than too few seeds, for it is +easy to thin out the plants, but rather difficult to transplant them. +The seeds are usually drilled in rows about twenty inches apart. Of +course, if the soil is rather warm and moist at planting-time, fewer +seeds will be needed than when germination is likely to be slow. + +[Illustration: FIG. 211. SUGAR-BEET] + +A good rotation should always be planned for this beet. A very +successful one is as follows: for the first year, corn heavily +fertilized with stable manure; for the second year, sugar-beets; for the +third year, oats or barley; for the fourth year, clover; then go back +again to corn. In addition to keeping the soil fertile, there are two +gains from this rotation: first, the clean cultivation of the corn crop +just ahead of the beets destroys many of the weed seeds; second, the +beets must be protected from too much nitrogen in the soil, for an +excess of nitrogen makes a beet too large to be rich in sugar. The +manure, heavily applied to the corn, will leave enough nitrogen and +other plant food in the soil to make a good crop of beets and avoid any +danger of an excess. + +When the outside leaves of the beet take on a yellow tinge and drop to +the ground, the beets are ripe. The mature beets are richer in sugar +than the immature, therefore they should not be harvested too soon. They +may remain in the ground without injury for some time after they are +ripe. Cold weather does not injure the roots unless it is accompanied by +freezing and thawing. + +[Illustration: FIG. 212. SUGAR-BEETS ON THE WAY TO A FACTORY] + +The beets are harvested by sugar-beet pullers or by hand. If the roots +are to be gathered by hand they are usually loosened by plowing on each +side of them. If the roots are stored they should be put in long, narrow +piles and covered with straw and earth to protect them from frost. A +ventilator placed at the top of the pile will enable the heat and +moisture to escape. If the beets get too warm they will ferment and some +of their sugar will be lost. + + +=Sugar-Cane.= Sugar-cane is grown along the Gulf of Mexico and the South +Atlantic coast. In Mississippi, in Alabama, Florida, Georgia, South +Carolina, northern Louisiana, and in northern Texas it is generally made +into sirup. In southern Louisiana and southern Texas the cane is usually +crushed for sugar or for molasses. + +[Illustration: FIG. 213. STALK OF SUGAR-CANE +_A-B_, joints of cane showing roots; _B-C_, stem; _C-D_, leaves] + +The sugar-cane is a huge grass. The stalk, which is round, is from one +to two inches in thickness. + +The stalks vary in color. Some are white, some yellow, some green, some +red, some purple, and some black, while others are a mixture of two or +three of these colors. As shown in Fig. 214 the stalk has joints at +distances of from two to six inches. These joints are called nodes, and +the sections between the nodes are known as internodes. The internodes +ripen from the roots upward, and as each ripens it casts its leaves. The +stalk, when ready for harvesting, has only a few leaves on the top. + +[Illustration: Fig. 214. STICK OF SUGAR-CANE +_A_, buds, or eyes; _C_, nodes; _D_, internodes; _X_, semi-transparent +dots in rows] + +Under each leaf and on alternate sides of the cane a bud, or "eye," +forms. From this eye the cane is usually propagated; for, while in +tropical countries the cane forms seeds, yet these seeds are rarely +fertile. When the cane is ripe it is stripped of leaves, topped, and cut +at the ground with a knife. The sugar is contained in solution in the +pith of the cane. + +Cane requires an enormous amount of water for its best growth, and where +the rainfall is not great enough, the plants are irrigated. It requires +from seventy-five to one hundred gallons of water to make a pound of +sugar. Cane does best where there is a rainfall of two inches a week. At +the same time a well-drained soil is necessary to make vigorous canes. + +The soils suited to this plant are those which contain large amounts of +fertilizing material and which can hold much water. In southern +Louisiana alluvial loams and loamy clay soils are cultivated. In +Georgia, Alabama, and Florida light, sandy soils, when properly +fertilized and worked, make good crops. + +[Illustration: FIG. 215. PLANTING SUGAR-CANE] + +[Illustration: FIG. 216. LOADING SUGAR-CANE] + +Cane is usually planted in rows from five to six feet apart. A trench is +opened in the center of the row with a plow and in this open furrow is +placed a continuous line of stalks which are carefully covered with +plow, cultivator, or hoe. From one to three continuous lines of stalks +are placed in the furrow. From two to six tons of seed cane are needed +for an acre. In favorable weather the cane soon sprouts and cultivation +begins. Cane should be cultivated at short intervals until the plants +are large enough to shade the soil. In Louisiana one planting of cane +usually gives two crops. The first is called plant cane; the second is +known as first-year stubble, or ratoon. Sometimes second-year stubble is +grown. + +[Illustration: FIG. 217. A COMMON TYPE OF SIRUP FACTORY] + +In Louisiana large quantities of tankage, cotton-seed meal, and acid +phosphate are used to fertilize cane-fields. Each country has its own +time for planting and harvesting. In Louisiana, for example, canes are +planted from October to April. In the United States cane is harvested +each year because of frost, but in tropical countries the stalks are +permitted to grow from fifteen to twenty-four months. + +On many farms a small mill, the rollers of which are turned by horses, +is used for crushing the juice out of the cane. The juice is then +evaporated in a kettle or pan. This equipment is very cheap and can +easily be operated by a small family. While these mills rarely extract +more than one half of the juice in the cane, the sirup made by them is +very palatable and usually commands a good price. Costly machinery which +saves most of the juice is used in the large commercial sugar houses. + + +SECTION XLVI. HEMP AND FLAX + +In the early ages of the world, mankind is supposed to have worn very +little or no clothing. Then leaves and the inner bark of trees were +fashioned into a protection from the weather. These flimsy garments were +later replaced by skins and furs. As man advanced in knowledge, he +learned how to twist wool and hairs into threads and to weave these into +durable garments. Still later, perhaps, he discovered that some plants +conceal under their outer bark soft, tough fibers that can be changed +into excellent cloth. Flax and hemp were doubtless among the first +plants to furnish this fiber. + +=Flax.= Among the fiber crops of the world, flax ranks next to cotton. +It is the material from which is woven the linen for sheets, towels, +tablecloths, shirts, collars, dresses, and a host of other articles. +Fortunately for man, flax will thrive in many countries and in many +climates. The fiber from which these useful articles are made, unlike +cotton fiber, does not come from the fruit, but from the stem. It is the +soft, silky lining of the bark which lies between the woody outside and +the pith cells of the stem. + +The Old World engages largely in flax culture and flax manufacture, but +in our country flax is grown principally for its seed. From the seeds we +make linseed oil, linseed-oil cake, and linseed meal. + +Flax grows best on deep, loamy soils, but also makes a profitable growth +on clay soils. With sufficient fertilizing material it can be grown on +sandy lands. Nitrogen is especially needed by this plant and should be +liberally supplied. To meet this demand for nitrogen, it pays to plant a +leguminous crop immediately before flax. + +[Illustration: FIG. 218. FLAX] + +After a mellow seed-bed has been made ready and after the weather is +fairly warm, sow, if a seed crop is desired, at the rate of from two to +three pecks an acre. A good seed crop will not be harvested if the +plants are too thick. On the other hand, if a fiber crop is to be +raised, it is desirable to plant more thickly, so that the stalks may +not branch, but run up into a single stem. From a bushel to two bushels +of seed is in this case used to an acre. Flax requires care and work +from start to finish. + +When the seeds are full and plump the flax is ready for harvesting. In +America a binder is generally used for cutting the stalks. Our average +yield of flax is from eight to fifteen bushels an acre. + +=Hemp.= Like flax, hemp adapts itself wonderfully to many countries and +many climates. However, in America most of our hemp is grown in +Kentucky. + +[Illustration: FIG. 219. CUTTING HEMP] + +Hemp needs soil rich enough to give the young plants a very rapid growth +in their early days so that they may form long fibers. To give this crop +abundant nitrogen without great cost, it should be grown in a rotation +which includes one of the legumes. Rich, well-drained bottom-lands +produce the largest yields of hemp, but uplands which have been heavily +manured make profitable yields. + +The ground for hemp is prepared as for other grain crops. The seed is +generally broadcasted for a fiber crop and then harrowed in. No +cultivation is required after seeding. + +If hemp is grown for seed, it is best to plant with a drill so that the +crop may be cultivated. The stalks after being cut are put in shocks +until they are dry. Then the seeds are threshed. Large amounts of hemp +seed are sold for caged birds and for poultry; it is also used for +paint-oils. + + +SECTION XLVII. BUCKWHEAT + +Buckwheat shares with rye and cowpeas the power to make a fairly good +crop on poor land. At the same time, of course, a full crop can be +expected only from fertile land. + +The three varieties most grown in America are the common gray, the +silver-hull, and the Japanese. The seeds of the common gray are larger +than the silver-hull, but not so large as the Japanese. The seeds from +the gray variety are generally regarded as inferior to the other two. +This crop is grown to best advantage in climates where the nights are +cool and moist. It matures more quickly than any other grain crop and is +remarkably free from disease. The yield varies from ten to forty bushels +an acre. Buckwheat does not seem to draw plant food heavily from the +soil and can be grown on the same land from year to year. + +In fertilizing buckwheat land, green manures and rich nitrogenous +fertilizers should be avoided. These cause such a luxuriant growth that +the stalks lodge badly. + +The time of seeding will have to be settled by the height of the land +and by the climate. In northern climates and in high altitudes the +seeding is generally done in May or June. In southern climates and in +low altitudes the planting may wait until July or August. The plant +usually matures in about seventy days. It cannot stand warm weather at +blooming-time, and must always be planted so that it may escape warm +weather in its blooming period and cold weather in its maturing season. +The seeds are commonly broadcasted at an average rate of four pecks to +the acre. If the land is loose and pulverized, it should be rolled. + +[Illustration: FIG. 220. BUCKWHEAT IN SHOCK] + +Buckwheat ripens unevenly and will continue to bloom until frost. +Harvesting usually begins just after the first crop of seeds have +matured. To keep the grains from shattering, the harvesting is best done +during damp or cloudy days or early in the morning while the dew is +still on the grain. The grain should be threshed as soon as it is dry +enough to go through the thresher. + +Buckwheat is grown largely for table use. The grain is crushed into a +dark flour that makes most palatable breakfast cakes. The grain, +especially when mixed with corn, is becoming popular for poultry food. +The middlings, which are rich in fats and protein, are prized for dairy +cows. + + +SECTION XLVIII. RICE + +The United States produces only about one half of the rice that it +consumes. There is no satisfactory reason for our not raising more of +this staple crop, for five great states along the Gulf of Mexico are +well adapted to its culture. + +[Illustration: FIG. 221. THRESHING RICE] + +There are two distinct kinds of rice, upland rice and lowland rice. +Upland rice demands in general the same methods of culture that are +required by other cereals, for example, oats or wheat. The growing of +lowland rice is considerably more difficult and includes the necessity +of flooding the fields with water at proper times. + +A stiff, half-clay soil with some loam is best suited to this crop. The +soil should have a clay subsoil to retain water and to give stiffness +enough to allow the use of harvesting-machinery. Some good rice soils +are so stiff that they must be flooded to soften them enough to admit of +plowing. Plow deeply to give the roots ample feeding-space. Good +tillage, which is too often neglected, is valuable. + +Careful seed-selection is perhaps even more needed for rice than for any +other crop. Consumers want kernels of the same size. Be sure that your +seed is free from red rice and other weeds. Drilling is much better +than broadcasting, as it secures a more even distribution of the seed. + +The notion generally prevails that flooding returns to the soil the +needed fertility. This may be true if the flooding-water deposits much +silt, but if the water be clear it is untrue, and fertilizers or +leguminous crops are needed to keep up fertility. Cowpeas replace the +lost soil-elements and keep down weeds, grasses, and red rice. + +Red rice is a weed close kin to rice, but the seed of one will not +produce the other. Do not allow it to get mixed and sowed with your rice +seed or to go to seed in your field. + + +SECTION XLIX. THE TIMBER CROP + +Forest trees are not usually regarded as a crop, but they are certainly +one of the most important crops. We should accustom ourselves to look on +our trees as needing and as deserving the same care and thought that we +give to our other field crops. The total number of acres given to the +growth of forest trees is still enormous, but we should each year add to +this acreage. + +Unfortunately very few forests are so managed as to add yearly to their +value and to preserve a model stand of trees. Axmen generally fell the +great trees without thought of the young trees that should at once begin +to fill the places left vacant by the fallen giants. Owners rarely study +their woodlands to be sure that the trees are thick enough, or to find +out whether the saplings are ruinously crowding one another. Disease is +often allowed to slip in unchecked. Old trees stand long after they have +outlived their usefulness. + +The farm wood-lot, too, is often neglected. As forests are being swept +away, fuel is of course becoming scarcer and more costly. Every farmer +ought to plant trees enough on his waste land to make sure of a constant +supply of fuel. The land saved for the wood-lot should be selected from +land unfit for cultivation. Steep hillsides, rocky slopes, ravines, +banks of streams--these can, without much expense or labor, be set in +trees and insure a never-ending fuel supply. + +[Illustration: FIG. 222. WOOD LOT +Before proper treatment] + +The most common enemies of the forest crop are: + +First, forest fires. The waste from forest fires in the United States is +most startling. Many of these fires are the result of carelessness or +ignorance. Most of the states have made or are now making laws to +prevent and to control such fires. + +Second, fungous diseases. The timber loss from these diseases is +exceedingly great. + +Third, insects of many kinds prey on the trees. Some strip all the +leaves from the branches. Others bore into the roots, trunk, or +branches. Some lead to a slow death; others are more quickly fatal. + +Fourth, improper grazing. Turning animals into young woods may lead to +serious loss. The animals frequently ruin young trees by eating all the +foliage. Hogs often unearth and consume most of the seeds needed for a +good growth. + +[Illustration: FIG. 223. WOOD LOT +After proper treatment] + +The handling of forests is a business just as the growing of corn is a +business. In old forests, dead and dying trees should be cut. Trees that +occupy space and yet have little commercial value should give way to +more valuable trees. A quick-growing tree, if it is equally desirable, +should be preferred to a slow grower. An even distribution of the trees +should be secured. + +In all there are about five hundred species of trees which are natives +of the United States. Probably not over seventy of these are desirable +for forests. In selecting trees to plant or to allow to grow from their +own seeding, pick those that make a quick growth, that have a steady +market value, and that suit the soil, the place of growth, and the +climate. + + +SECTION L. THE FARM GARDEN + +Every farmer needs a garden in which to grow not only vegetables but +small fruits for the home table. + +The garden should always be within convenient distance of the farmhouse. +If possible, the spot selected should have a soil of mixed loam and +clay. Every foot of soil in the garden should be made rich and mellow by +manure and cultivation. The worst soils for the home garden are light, +sandy soils, or stiff, clayey soils; but any soil, by judicious and +intelligent culture, can be made suitable. + +In laying out the garden we should bear in mind that hand labor is the +most expensive kind of labor. Hence we should not, as is commonly done, +lay off the garden spot in the form of a square, but we should mark off +for our purpose a long, narrow piece of land, so that the cultivating +tools may all be conveniently drawn by a horse or a mule. The use of the +plow and the horse cultivator enables the cultivation of the garden to +be done quickly, easily, and cheaply. + +Each vegetable or fruit should be planted in rows, and not in little +patches. Beginning with one side of the garden the following plan of +arrangement is simple and complete: two rows to corn for table use; two +to cabbages, beets, radishes, and eggplants; two to onions, peas, and +beans; two to oyster-plants, okra, parsley, and turnips; two to +tomatoes; then four on the other side can be used for strawberries, +blackberries, raspberries, currants, and gooseberries. + +[Illustration: FIG. 224. WHERE DELICIOUS GARDEN VEGETABLES GROW] + +The garden, when so arranged, can be tilled in the spring and tended +throughout the growing season with little labor and little loss of time. +In return for this odd-hour work, the farmer's family will have +throughout the year an abundance of fresh, palatable, and health-giving +vegetables and small fruits. + +The keynote of successful gardening is to stir the soil. Stir it often +with four objects in view: + + 1. To destroy weeds. + + 2. To let air enter the soil. + + 3. To enrich the soil by the action of the air. + + 4. To retain the moisture by preventing its evaporation. + + corn + corn + + cabbage beets radishes + cabbage beets eggplants + + onions peas beans + onions peas beans + + oyster-plants okra parsley parsnips + oyster-plants okra parsley parsnips + + tomatoes + tomatoes + + strawberries currants raspberries blackberries + strawberries currants raspberries blackberries + strawberries currants raspberries blackberries + strawberries currants raspberries blackberries + +[Illustration: FIG. 225. HOW TO LAY OUT THE GARDEN[1]] + +This illustration shows that practically every garden vegetable and all +the small fruits can be included in the farm garden, and all the work be +done by horse-drawn tools. + +[Footnote 1: The number of rows and arrangement of the vegetables in the +outline above are merely suggestive. They should be changed to meet the +needs and the tastes of each particular family.] + + + + +CHAPTER IX + +FEED STUFFS + +SECTION LI. GRASSES + + +Under usual conditions no farmer expects to grow live stock successfully +and economically without setting apart a large part of his land for the +growth of mowing and pasture crops. Therefore to the grower of stock the +management of grass crops is all-important. + +In planting either for a meadow or for a pasture, the farmer should mix +different varieties of grass seeds. Nature mixes them when she plants, +and Nature is always a trustworthy teacher. + +In planting for a pasture the aim should be to sow such seeds as will +give green grass from early spring to latest fall. In seeding for a +meadow such varieties should be sowed together as ripen about the same +time. + +Even in those sections of the country where it grows sparingly and where +it is easily crowded out, clover should be mixed with all grasses sowed, +for it leaves in the soil a wealth of plant food for the grasses coming +after it to feed on. Nearly every part of our country has some clover +that experience shows to be exactly suited to its soil and climate. +Study these clovers carefully and mix them with your grass seed. + +The reason for mixing clover and grass is at once seen. The true +grasses, so far as science now shows, get all their nitrogen from the +soil; hence they more or less exhaust the soil. But, as several times +explained in this book, the clovers are legumes, and all legumes are +able by means of the bacteria that live on their roots to use the free +nitrogen of the air. Hence without cost to the farmer these clovers help +the soil to feed their neighbors, the true grasses. For this reason some +light perennial legume should always be added to grass seed. + +[Illustration: FIG. 226. SINGLE PLANT OF GIANT MILLET] + +It is not possible for grasses to do well in a soil that is full of +weeds. For this reason it is always best to sow grass in fields from +which cultivated crops have just been taken. Soil which is to have grass +sowed in it should have its particles pressed together. The small grass +seeds cannot take root and grow well in land that has just been plowed +and which, consequently, has its particles loose and comparatively far +apart. On the other hand, land from which a crop of corn or cotton has +just been harvested is in a compact condition. The soil particles are +pressed well together. Such land when mellowed by harrowing makes a +splendid bed for grass seeds. A firm soil draws moisture up to the +seeds, while a mellow soil acts as a blanket to keep moisture from +wasting into the air, and at the same time allows the heated air to +circulate in the soil. + +In case land has to be plowed for grass-seeding, the plowing should be +done as far as possible in advance of the seeding. Then the plowed land +should be harrowed several times to get the land in a soft, mellow +condition. + +If the seed-bed be carefully prepared, little work on the ground is +necessary after the seeds are sowed. One light harrowing is sufficient +to cover the broadcast seeds. This harrowing should always be done as +soon as the seeds are scattered, for if there be moisture in the soil +the tiny seeds will soon sprout, and if the harrowing be done after +germination is somewhat advanced, the tender grass plants will be +injured. + +There are many kinds of pasture and meadow grasses. In New England, +timothy, red clover, and redtop are generally used for the mowing crop. +For permanent pasture, in addition to those mentioned, there should be +added white clover and either Kentucky or Canadian blue grass. In the +Southern states a good meadow or pasture can be made of orchard grass, +red clover, and redtop. For a permanent pasture in the South, Japan +clover, Bermuda, and such other local grasses as have been found to +adapt themselves readily to the climate should be added. In the Middle +States temporary meadows and pastures are generally made of timothy and +red clover, while for permanent pastures white clover and blue grass +thrive well. In the more western states the grasses previously suggested +are readily at home. Alfalfa is proving its adaptability to nearly all +sections and climates, and is in many respects the most promising grass +crop of America. + +[Illustration: FIG. 227. BERMUDA] + +It hardly ever pays to pasture meadows, except slightly, the first +season, and then only when the soil is dry. It is also poor policy to +pasture any kind of grass land early in the spring when the soil is wet, +because the tramping of animals crushes and destroys the crowns of the +plants. After the first year the sward becomes thicker and tougher, and +the grass is not at all injured if it is grazed wisely. + +[Illustration: FIG. 228. ALFALFA THE WONDERFUL +The first crop of the season is being cut and stored for winter] + +The state of maturity at which grass should be harvested to make hay of +the best quality varies somewhat with the different grasses and with the +use which is to be made of the hay. Generally speaking, it is a good +rule to cut grass for hay just as it is beginning to bloom or just after +the bloom has fallen. All grasses become less palatable to stock as they +mature and form seed. If grass be allowed to go to seed, most of the +nutrition in the stalk is used to form the seed. + +[Illustration: FIG. 229. HARVESTING ALFALFA] + +Hence a good deal of food is lost by waiting to cut hay until the seeds +are formed. + +Pasture lands and meadow lands are often greatly improved by replowing +and harrowing in order to break up the turf that forms and to admit air +more freely into the soil. The plant-roots that are destroyed by the +plowing or harrowing make quickly available plant food by their decay, +and the physical improvement of the soil leads to a thicker and better +stand. In the older sections of the country commercial fertilizer can be +used to advantage in producing hay and pasturage. If, however, clover +has just been grown on grass land or if it is growing well with the +grass, there is no need to add nitrogen. If the grass seems to lack +sufficient nourishment, add phosphoric acid and potash. However, grass +not grown in company with clover often needs dried blood, nitrate of +soda, or some other nitrogen-supplying agent. Of course it is understood +that no better fertilizer can be applied to grass than barnyard manure. + + +SECTION LII. LEGUMES + +Often land which was once thought excellent is left to grow up in weeds. +The owner says that the land is worn out, and that it will not pay to +plant it. What does "worn out" mean? Simply that constant cropping has +used up the plant food in the land. Therefore, plants on worn-out land +are too nearly starved to yield bountifully. Such wearing out is so +easily prevented that no owner ought ever to allow his land to become +poverty-stricken. But in case this misfortune has happened, how can the +land be again made fertile? + +On page 24 you learned that phosphoric acid, potash, and nitrogen are +the foods most needed by plants. "Worn out," then, to put it in +another way, usually means that a soil has been robbed of one of these +plant necessities, or of two or of all three. To make the land once more +fruitful it is necessary to restore the missing food or foods. How can +this be done? Two of these plant foods, namely, phosphoric acid and +potash, are minerals. If either of these is lacking, it can be supplied +only by putting on the land some fertilizer containing the missing food. +Fortunately, however, nitrogen, the most costly of the plant foods, can +be readily and cheaply returned to poor land. + +[Illustration: FIG. 230. ALFALFA READY FOR THE THIRD CUTTING] + +As explained on page 32 the leguminous crops have the power of drawing +nitrogen from the air and, by means of their root-tubercles, of storing +it in the soil. Hence by growing these crops on poor land the expensive +nitrogen is quickly restored to the soil, and only the two cheaper plant +foods need be bought. How important it is then to grow these leguminous +plants! Every farmer should so rotate his planting that at least once +every two or three years a crop of legumes may add to the fruitfulness +of his fields. + +Moreover these crops help land in another way. They send a multitude of +roots deep into the ground. These roots loosen and pulverize the soil, +and their decay, at the end of the growing season, leaves much humus in +the soil. Land will rarely become worn out if legumes are regularly and +wisely grown. + +From the fact that they do well in so many different sections and in so +many different climates, the following are the most useful legumes: +alfalfa, clovers, cowpeas, vetches, and soy beans. + +=Alfalfa.= Alfalfa is primarily a hay crop. It thrives in the Far West, +in the Middle West, in the North, and in the South. In fact, it will do +well wherever the soil is rich, moist, deep, and underlaid by an open +subsoil. The vast areas given to this valuable crop are yearly +increasing in every section of the United States. Alfalfa, however, +unlike the cowpea, does not take to poor land. For its cultivation, +therefore, good fertile land that is moist but not water-soaked should +be selected. + +Good farmers are partial to alfalfa for three reasons. First, it yields +a heavy crop of forage or hay. Second, being a legume, it improves the +soil. Third, one seeding lasts a long time. This length of life may, +however, be destroyed by pasturing or abusing the alfalfa. + +[Illustration: FIG. 231. SHEEP FATTENING ON ALFALFA STUBBLE] + +Alfalfa is different from most plants in this respect: the soil in which +it grows must have certain kinds of bacteria in it. These cause the +growth of tubercles on the roots. These bacteria, however, are not +always present in land that has not been planted in alfalfa. Hence if +this plant is to be grown successfully these helpful bacteria must +sometimes be supplied artificially. + +There are two very easy ways of supplying the germs. First, fine soil +from an alfalfa field may be scattered broadcast over the fields to be +seeded. Second, a small mass of alfalfa tubercle germs may be put into a +liquid containing proper food to make these germs multiply and grow; +then the seeds to be planted are soaked in this liquid in order that +the germs may fasten on the seeds. + +Before the seeds are sowed the soil should be mellowed. Over this +well-prepared land about twenty pounds of seed to the acre should be +scattered. The seed may be scattered by hand or by a seed-sower. Cover +with a light harrow. The time of planting varies somewhat with the +climate. Except where the winters are too severe the seed may be sowed +either in the spring or in the fall. In the South sow only in the fall. + +[Illustration: FIG. 232. HERD OF DAIRY CATTLE GRAZING ON ALFALFA STUBBLE] + +During the first season one mowing, perhaps more, is necessary to insure +a good stand and also to keep down the weeds. When the first blossoms +appear in the early summer, it is time to start the mower. After this +the alfalfa should be cut every two, three, or four weeks. The number of +times depends on the rapidity of growth. + +This crop rarely makes a good yield the first year, but if a good stand +be secured, the yield steadily increases. After a good stand has been +secured, a top-dressing of either commercial fertilizer or stable manure +will be very helpful. An occasional cutting-up of the sod with a disk +harrow does much good. + +=Clovers.= The different kinds of clovers will sometimes grow on hard or +poor soil, but they do far better if the soil is enriched and properly +prepared before the seed is sowed. In many parts of our country it has +been the practice for generations to sow clover seed with some of the +grain crops. Barley, wheat, oats, and rye are the crops with which +clover is usually planted, but many good farmers now prefer to sow the +seed only with other grass seed. Circumstances must largely determine +the manner of seeding. + +Crimson clover, which is a winter legume, usually does best when seeded +alone, although rye or some other grain often seems helpful to it. This +kind of clover is an excellent crop with which to follow cotton or corn. +It is most conveniently sowed at the last cultivation of these crops. + +Common red clover, which is the standard clover over most of the +country, is usually seeded with timothy or with orchard grass or with +some other of the grasses. In sowing both crimson and red clover, about +ten to fifteen pounds of seed for each acre are generally used. + +To make good pastures, white and Japan clover are favorites. White +clover does well in most parts of America, and Japan clover is +especially valuable in warm Southern climates. Both will do well even +when the soil is partly shaded, but they do best in land fully open to +the sun. + +Careful attention is required to cure clover hay well. The clover should +always be cut before it forms seed. The best time to cut is when the +plants are in full bloom. + +[Illustration: FIG. 233. CRIMSON CLOVER] + +Let the mower be started in the morning. Then a few hours later run over +the field with the tedder. This will loosen the hay and let in air and +sunshine. If the weather be fair let the hay lie until the next day, and +then rake it into rows for further drying. After being raked, the hay +may either be left in the rows for final curing or it may be put in +cocks. If the weather be unsettled, it is best to cock the hay. Many +farmers have cloth covers to protect the cocks and these often aid +greatly in saving the hay crop in a rainy season. In case the hay is put +in cocks, it should be opened for a final drying before it is housed. + +=Cowpeas.= The cowpea is an excellent soil-enricher. It supplies more +fertilizing material to turn into the soil, in a short time and at small +cost, than any other crop. Moreover, by good tillage and by the use of a +very small amount of fertilizer, the cowpea can be grown on land too +poor to produce any other crop. Its roots go deep into the soil. Hence +they gather plant food and moisture that shallow-rooted plants fail to +reach. These qualities make it an invaluable help in bringing worn-out +lands back to fertility. + +The cowpea is a warm-weather legume. In the United States it succeeds +best in the south and southwest. It has, however, in recent years been +grown as far north as Massachusetts, New York, Ohio, Michigan, and +Minnesota, but in these cold climates other legumes are more useful. +Cowpeas should never be planted until all danger of frost is past. Some +varieties make their full growth in two months; others need four months. + +There are about two hundred varieties of cowpeas. These varieties differ +in form, in the size of seed and of pod, in the color of seed and of +pod, and in the time of ripening. They differ, too, in the manner of +growth. Some grow erect; others sprawl on the ground. In selecting +varieties it is well to choose those that grow straight up, those that +are hardy, those that fruit early and abundantly, and those that hold +their leaves. The variety selected for seed should also suit the land +and the climate. + +The cowpea will grow in almost any soil. It thrives best and yields most +bountifully on well-drained sandy loams. The plant also does well on +clay soils. On light, sandy soils a fairly good crop may be made, but on +such soils, wilt and root-knot are dangerous foes. A warm, moist, +well-pulverized seed-bed should always be provided. Few plants equal the +cowpea in repaying careful preparation. + +[Illustration: FIG. 234. COWPEAS] + +If this crop is grown for hay, the method of seeding and cultivating +will differ somewhat from the method used when a seed crop is desired. +When cowpeas are planted for hay the seeds should be drilled or +broadcasted. If the seeds are small and the land somewhat rich, about +four pecks should be sowed on each acre. If the seeds are comparatively +large and the soil not so fertile, about six pecks should be sowed to +the acre. It is safer to disk in the seeds when they are sowed broadcast +than it is to rely on a harrow to cover them. In sowing merely for a +hay crop, it is a good practice to mix sorghum, corn, soy beans, or +millet with the cowpeas. The mixed hay is more easily harvested and more +easily cured than unmixed cowpea hay. Shortly after seeding, it pays to +run over the land lightly with a harrow or a weeder in order to break +any crust that may form. + +Mowing should begin as soon as the stalks and the pods have finished +growing and some of the lower leaves have begun to turn yellow. An +ordinary mower is perhaps the best machine for cutting the vines. If +possible, select only a bright day for mowing and do not start the +machine until the dew on the vines is dried. Allow the vines to remain +as they fell from the mower till they are wilted; then rake them into +windrows. The vines should generally stay in the windrows for two or +three days and be turned on the last day. They should then be put in +small, airy piles or piled around a stake that has crosspieces nailed to +it. The drying vines should never be packed; air must circulate freely +if good hay is to be made. As piling the vines around stakes is somewhat +laborious, some growers watch the curing carefully and succeed in +getting the vines dry enough to haul directly from the windrows to the +barns. Never allow the vines to stay exposed to too much sunshine when +they are first cut. If the sun strikes them too strongly, the leaves +will become brittle and shatter when they are moved. + +When cowpeas are grown for their pods to ripen, the seeds should be +planted in rows about a yard apart. From two to three pecks of seeds to +an acre should be sufficient. The growing plants should be cultivated +two or three times with a good cultivator. Cowpeas were formerly +gathered by hand, but such a method is of course slow and expensive. +Pickers are now commonly used. + +Some farmers use the cowpea crop only as a soil-enricher. Hence they +neither gather the seeds nor cut the hay, but plow the whole crop into +the soil. There is an average of about forty-seven pounds of nitrogen in +each ton of cowpea vines. Most of this valuable nitrogen is drawn by the +plants from the air. This amount of nitrogen is equal to that contained +in 9500 pounds of stable manure. In addition each ton of cowpea vines +contains ten pounds of phosphoric acid and twenty-nine pounds of potash. + +There is danger in plowing into the soil at one time any bountiful green +crop like cowpeas. As already explained on page 10, a process +called capillarity enables moisture to rise in the soil as plants need +it. Now if a heavy cowpea crop or any other similar crop be at one +plowing turned into the soil, the soil particles will be so separated as +to destroy capillarity. Too much vegetation turned under at once may +also, if the weather be warm, cause fermentation to set in and "sour the +land." Both of these troubles may be avoided by cutting up the vines +with a disk harrow or other implement before covering them. + +The custom of planting cowpeas between the rows at the last working of +corn is a good one, and wherever the climate permits this custom should +be followed. + +=Vetches.= The vetches have been rapidly growing in favor for some +years. Stock eat vetch hay greedily, and this hay increases the flow of +milk in dairy animals and helps to keep animals fat and sleek. Only two +species of vetch are widely grown. These are the tare, or spring vetch, +and the winter, or hairy, vetch. Spring vetch is grown in comparatively +few sections of our country. It is, however, grown widely in England and +northern continental Europe. What we say here will be confined to hairy +vetch. + +After a soil has been supplied with the germs needed by this plant, the +hairy vetch is productive on many different kinds of soil. The plant is +most vigorous on fertile loams. By good tillage and proper fertilization +it may be forced to grow rather bountifully on poor sandy and clay +loams. Acid or wet soils are not suited to vetch. Lands that are too +poor to produce clovers will frequently yield fair crops of vetch. If +this is borne in mind, many poor soils may be wonderfully improved by +growing on them this valuable legume. + +[Illustration: FIG. 235. VETCH] + +Vetch needs a fine well-compacted seed-bed, but it is often sowed with +good results on stubble lands and between cotton and corn rows, where it +is covered by a cultivator or a weeder. + +The seeds of the vetch are costly and are brought chiefly from Germany, +where this crop is much prized. The pods ripen so irregularly that they +have to be picked by hand. + +In northern climates early spring sowing is found most satisfactory. In +southern climates the seeding is best done in the late summer or early +fall. As the vetch vines have a tendency to trail on the ground, it is +wisest to plant with the vetch some crop like oats, barley, rye, or +wheat. These plants will support the vetch and keep its vines from being +injured by falling on the ground. Do not use rye with vetch in the +South. It ripens too early to be of much assistance. If sowed with oats +the seeding should be at the rate of about twenty or thirty pounds of +vetch and about one and a half or two bushels of oats to the acre. Vetch +is covered in the same way as wheat and rye. + +Few crops enrich soil more rapidly than vetch if the whole plant is +turned in. It of course adds nitrogen to the soil and at the same time +supplies the soil with a large amount of organic matter to decay and +change to humus. As the crop grows during the winter, it makes an +excellent cover to prevent washing. Many orchard-growers of the +Northwest find vetch the best winter crop for the orchards as well as +for the fields. + +=Soy, or Soja, Bean.= In China and Japan the soy bean is grown largely +as food for man. In the United States it is used as a forage plant and +as a soil-improver. It bids fair to become one of the most popular of +the legumes. Like the cowpea, this bean is at home only in a warm +climate. Some of the early-ripening varieties have, however, been +planted with fair success in cold climates. + +While there are a large number of varieties of the soy bean, only about +a dozen are commonly grown. They differ mainly in the color, size, and +shape of the seeds, and in the time needed for ripening. Some of the +varieties are more hairy than others. + +Soy beans may take many places in good crop-rotations, but they are +unusually valuable in short rotations with small grains. The grains can +be cut in time for the beans to follow them, and in turn the beans can +be harvested in the early fall and make way for another grain crop. + +It should always be remembered that soy beans will not thrive unless the +land on which they are to grow is already supplied, or is supplied at +the time of sowing, with bean bacteria. + +[Illustration: FIG. 236. CHINESE SOY BEANS] + +The plant will grow on many different kinds of soil, but it needs a +richer soil than the cowpea does. As the crop can gather most of its own +nitrogen, it generally requires only the addition of phosphoric acid and +potash for its growth on poor land. When the first crop is seeded, apply +to each acre four hundred pounds of a fertilizing mixture which contains +about ten per cent of phosphoric acid, four per cent of potash, and from +one to two per cent of nitrogen. + +If the crop is planted for hay or for grazing, mellow the ground well, +and then broadcast or drill in closely about one and a half bushels of +seed to each acre. Cover from one to two inches deep, but never allow a +crust to form over the seed, for the plant cannot break through a crust +well. When the beans are planted for seeds, a half bushel of seed to the +acre is usually sufficient. The plants should stand in the rows from +four to six inches apart, and the rows should be from thirty to forty +inches from one another. Never plant until the sun has thoroughly warmed +the land. The bean may be sowed, however, earlier than cowpeas. A most +convenient time is just after corn is planted. The rows should be +cultivated often enough to keep out weeds and grass and to keep a good +dust mulch, but the cultivation must be shallow. + +[Illustration: FIG. 237. SOY BEANS] + +As soy beans are grown for hay and also for seed, the harvesting will, +as with the other legumes, be controlled by the purpose for which the +crop was planted. In harvesting for a hay crop it is desirable to cut +the beans after the pods are well formed but before they are fully +grown. If the cutting is delayed until the pods are ripe, the fruit will +shatter badly. There is a loss, too, in the food value of the stems if +the cutting is late. The ordinary mowing-machine with a rake attached is +generally the machine used for cutting the stalks. The leaves should be +most carefully preserved, for they contain much nourishment for stock. + +[Illustration: FIG. 238. SOY BEANS IN CORN] + +Whenever the beans are grown for seeds, harvesting should begin when +three fourths of the leaves have fallen and most of the pods are ripe. +Do not wait, however, until the pods are so dry that they have begun to +split and drop their seeds. A slight amount of dampness on the plants +aids the cutting. The threshing may be done with a flail, with +pea-hullers, or with a grain-threshing machine. + +The beans produce more seed to the acre than cowpeas do. Forty bushels +is a high yield. The average yield is between twenty and thirty bushels. + + DESCRIPTIVE TABLE + + ADAPTATION AS +Crop FOOD FOR ANIMALS LIFE REMARKS + +Alfalfa Hay Perennial All animals like it; hogs + eat it even when it is dry. +Red clover Hay and pasture Perennial Best of the clovers for hay. +Alsike clover Hay and pasture Perennial Seeds itself for twenty + years.

The general rule is, poor +stock, poor people. All the prosperous nations of the globe, especially +the grain-growing nations, get a large share of their wealth from +raising improved stock. The stock bred by these nations is now, however, +very different from the stock raised by the same nations years ago. As +soon as man began to progress in the art of agriculture he became +dissatisfied with inferior stock. He therefore bent his energies to +raise the standard of excellence in domestic animals. + +By slow stages of animal improvement the ugly, thin-flanked wild boar of +early times has been transformed into the sleek Berkshire or the +well-rounded Poland-China. In the same manner the wild sheep of the Old +World have been developed into wool and mutton breeds of the finest +excellence. By constant care, attention, and selection the thin, +long-legged wild ox has been bred into the bounteous milk-producing +Jerseys and Holsteins or into the Shorthorn mountains of flesh. From the +small, bony, coarse, and shaggy horse of ancient times have descended +the heavy Norman, or Percheron, draft horse and the fleet Arab courser. + +The matter of meat-production is one of vital importance to the human +race, for animal food must always supply a large part of man's ration. + +Live stock of various kinds consume the coarser foods, like the grasses, +hays, and grains, which man cannot use. As a result of this consumption +they store in their bodies the exact substances required for building up +the tissues of man's body. + +When the animal is used by man for food, one class of foods stored away +in the animal's body produces muscle; another produces fat, heat, and +energy. The food furnished by the slaughter of animals seems necessary +to the full development of man. It is true that the flesh of an animal +will not support human life so long as would the grain that the animal +ate while growing, but it is also true that animal food does not require +so much of man's force to digest it. Hence the use of meat forces a part +of man's life-struggle on the lower animal. + +When men feed grain to stock, the animals receive in return power and +food in their most available forms. Men strengthen the animal that they +themselves may be strengthened. One of the great questions, then, for +the stock-grower's consideration is how to make the least amount of food +fed to animals produce the most power and flesh. + + +SECTION LIII. HORSES + +While we have a great many kinds of horses in America, horses are not +natives of this country. Just where wild horses were first tamed and +used is not certainly known. It is believed that in early ages the horse +was a much smaller animal than it now is, and that it gradually attained +its present size. Where food was abundant and nutritious and the climate +mild and healthful, the early horses developed large frames and heavy +limbs and muscles; on the other hand, where food was scarce and the +climate cold and bleak, the animals remained as dwarfed as the ponies of +the Shetland Islands. + +[Illustration: FIG. 239. THE FAMILY PET] + +One of the first records concerning the horse is found in Genesis xlix, +17, where Jacob speaks of "an adder that biteth the horse heels." +Pharaoh took "six hundred chosen chariots" and "with all the horses and +chariots" pursued the Israelites. The Greeks at first drove the horse +fastened to a rude chariot; later they rode on its back, learning to +manage the animal with voice or switch and without either saddle or +bridle. This thinking people soon invented the snaffle bit, and both +rode and drove with its aid. The curb bit was a Roman invention. Shoeing +was not practiced by either Greeks or Romans. Saddles and harnesses were +at first made of skins and sometimes of cloth. + +Among the Tartars of middle and northern Asia and also among some other +nations, mare's milk and the flesh of the horse are used for food. Old +and otherwise worthless horses are regularly fattened for the meat +markets of France and Germany. Various uses are made of the different +parts of a horse's body. The mane and tail are used in the manufacture +of mattresses, and also furnish a haircloth for upholstering; the skin +is tanned into leather; the hoofs are used for glue, and the bones for +making fertilizer. + +[Illustration: FIG. 240. PERCHERON HORSE (A DRAFT TYPE)] + +Climate, food, and natural surroundings have all aided in producing +changes in the horse's form, size, and appearance. The varying +circumstances under which horses have been raised have given rise to the +different breeds. In addition, the masters' needs had much to do in +developing the type of horses wanted. Some masters desired work horses, +and kept the heavy, muscular, stout-limbed animals; others desired +riding and driving horses, so they saved for their use the light-limbed, +angular horses that had endurance and mettle. The following table gives +some of the different breeds and the places of their development: + +[Illustration: FIG. 241. +Diagram shows the proper shape of the fore and hind legs of a horse. +When the straight lines divide the legs equally, the leg action is +straight and regular] + + I. _Draft, or Heavy, Breeds_ + + 1. Percheron, from the province of Perche, France. + 2. French Draft, developed in France. + 3. Belgian Draft, developed by Belgian farmers. + 4. Clydesdale, the draft horse of Scotland. + 5. Suffolk Punch, from the eastern part of England. + 6. English Shire, also from the eastern part of England. + + II. _Carriage, or Coach, Breeds_ + + 1. Cleveland Bay, developed in England. + 2. French Coach, the gentleman's horse of France. + 3. German Coach, from Germany. + 4. Oldenburg Coach, Oldenburg, Germany. + 5. Hackney, the English high-stepper. + + III. _Light, or Roadster, Breeds_ + + 1. American Trotter, developed in America. + 2. Thoroughbred, the English running horse. + 3. American Saddle Horse, from Kentucky and Virginia. + +There is a marked difference in the form and type of these horses, and +on this difference their usefulness depends. + +[Illustration: FIG. 242. WIDE HOCK +This horse stands great strains and is not fatigued easily] + +[Illustration: FIG. 243. NARROW HOCK +This horse becomes exhausted very easily] + +The draft breeds have short legs, and hence their bodies are +comparatively close to the ground. The depth of the body should be about +the same as the length of leg. All draft horses should have upright +shoulders, so as to provide an easy support for the collar. The hock +should be wide, so that the animal shall have great leverage of muscle +for pulling. A horse having a narrow hock is not able to draw a heavy +load and is easily exhausted and liable to curb-diseases (see Figs. 242 +and 243). + +[Illustration: FIG. 244. THE ROADSTER TYPE] + +The legs of all kinds of horses should be straight; a line dropped from +the point of the shoulder to the ground should divide the knees, canon, +fetlock, and foot into two equal parts. When the animal is formed in +this way the feet have room to be straight and square, with just the +breadth of a hoof between them (Fig. 241). + +Roadsters are lighter in bone and less heavily muscled; their legs are +longer than those of the draft horses and, as horsemen say, more +"daylight" can be seen under the body. The neck is long and thin, but +fits nicely into the shoulders. The shoulders are sloping and long and +give the roadster ability to reach well out in his stride. The head is +set gracefully on the neck and should be carried with ease and +erectness. + +Every man who is to deal with horses ought to become, by observation and +study, an expert judge of forms, qualities, types, defects, and +excellences. + +[Illustration: FIG. 245. SIDE VIEW OF LEGS +The diagram shows how the straight lines ought to cross the legs of a +properly shaped horse] + +The horse's foot makes an interesting study. The horny outside protects +the foot from mud, ice, and stones. Inside the hoof are the bones and +gristle that serve as cushions to diminish the shock received while +walking or running on hard roads or streets. When shoeing the horse the +frog should not be touched with the knife. It is very seldom that any +cutting need be done. Many blacksmiths do not know this and often +greatly injure the foot. + +Since the horse has but a small stomach, the food given should not be +too bulky. In proportion to the horse's size, its grain ration should be +larger than that of other animals. Draft horses and mules, however, can +be fed a more bulky ration than other horses, because they have larger +stomachs and consequently have more room to store food. + +[Illustration: FIG. 246. HOW TO MEASURE A HORSE] + +The horse should be groomed every day. This keeps the pores of the skin +open and the hair bright and glossy. When horses are working hard, the +harness should be removed during the noon hour. During the cool seasons +of the year, whenever a horse is wet with sweat, it should on stopping +work, or when standing for awhile, be blanketed, for the animal is as +liable as man to get cold in a draft or from moisture evaporating +rapidly from its skin. + + EXERCISE + + If the pupil will take an ordinary tape measure, he can make some + measurements of the horse that will be very interesting as well as + profitable. Let him measure: + + 1. The height of the horse at the withers, 1 to 1. + 2. The height of the horse at croup, 2 to 2. + 3. Length of shoulder, 1 to 3. + 4. Length of back, 4. + 5. Length of head, 5. + 6. Depth of body, 6 to 6. + 7. Daylight under body, 7 to 7. + 8. Distance from point of shoulder to quarter, 3 to 3. + 9. Width of forehead. + 10. Width between hips. + + NOTE. Many interesting comparisons can be made (1) by + measuring several horses; (2) by studying the proportion between + parts of the same horse. + + PROPORTIONS OF A HORSE + + 1. How many times longer is the body than the head? Do you get the + same result from different horses? + + 2. How does the height at the withers compare with the height at + the croup? + + 3. How do these compare with the distance from quarter to shoulder? + + 4. How does the length of the head compare with the thickness of + the body and with the open space, or "daylight," under the body? + + +SECTION LIV. CATTLE + +All farm animals were once called _cattle_; now this term applies only +to beef and dairy animals--neat cattle. + +Our improved breeds are descended from the wild ox of Europe and Asia, +and have attained their size and usefulness by care, food, and +selection. The uses of cattle are so familiar that we need scarcely +mention them. Their flesh is a part of man's daily food; their milk, +cream, butter, and cheese are on most tables; their hides go to make +leather, and their hair for plaster; their hoofs are used for glue, and +their bones for fertilizers, ornaments, buttons, and many other +purposes. + +[Illustration: FIG. 247. A PRIZE-WINNER] + +There are two main classes of cattle--beef breeds and dairy breeds. The +principal breeds of each class are as follows: + + I. _Beef Breeds_ + + 1. Aberdeen-Angus, bred in Scotland, and often called _doddies_. + 2. Galloway, from Scotland. + 3. Shorthorn, an English breed of cattle. + 4. Hereford, also an English breed. + 5. Sussex, from the county of Sussex, England. + + II. _Dairy Breeds_ + + 1. Jersey, from the Isle of Jersey. + 2. Guernsey, from the Isle of Guernsey. + 3. Ayrshire, from Scotland. + 4. Holstein-Frisian, from Holland and Denmark. + 5. Brown Swiss, from Switzerland. + +Other breeds of cattle are Devon, Dutch Belted, Red-Polled, Kerry, and +West Highland. + +In general structure there is a marked difference between the beef and +dairy breeds. This is shown in Figs. 248, 249. The beef cow is square, +full over the back and loins, and straight in the back. The hips are +covered evenly with flesh, the legs full and thick, the under line, or +stomach line, parallel to the back line, and the neck full and short. +The eye should be bright, the face short, the bones of fine texture, and +the skin soft and pliable. + +[Illustration: FIG. 248. ABERDEEN-ANGUS COW (A BEEF TYPE)] + +The dairy cow is widely different from the beef cow. She shows a decided +wedge shape when you look at her from front, side, or rear. The back +line is crooked, the hip bones and tail bone are prominent, the thighs +thin and poorly fleshed; there is no breadth to the back, as in the beef +cow, and little flesh covers the shoulders; the neck is long and thin. + +The udder of the dairy cow is most important. It should be full but not +fleshy, be well attached behind, and extend well forward. The larger the +udder the more milk will be given. + +The skin of the dairy cow, like that of the beef breeds, should be soft +and pliable and the bones fine-textured. + +=The Dairy Type.= Because of lack of flesh on the back, loins, and +thighs, the cow of the dairy type is not profitably raised for beef, nor +is the beef so good as that of the beef types. This is because in the +dairy-animal food goes to produce milk rather than beef. In the same way +the beef cow gives little milk, since her food goes rather to fat than +to milk. For the same reasons that you do not expect a plow horse to win +on the race track, you do not expect a cow of the beef type to win +premiums as a milker. + +[Illustration: FIG. 249. JERSEY COW (A DAIRY TYPE)] + +"Scrub" cattle are not profitable. They mature slowly and consequently +consume much food before they are able to give any return for it. Even +when fattened, the fat and lean portions are not evenly distributed, +and "choice cuts" are few and small. + +By far the cheapest method of securing a healthy and profitable herd of +dairy or beef cattle is to save only the calves whose sires are +pure-bred animals and whose mothers are native cows. In this way farmers +of even little means can soon build up an excellent herd. + +=Improving Cattle.= The fact that it is not possible for every farmer to +possess pure-bred cattle is no reason why he should not improve the +stock he has. He can do this by using pure-bred sires that possess the +qualities most to be desired. Scrub stock can be quickly improved by the +continuous use of good sires. It is never wise to use grade, or +cross-bred, sires, since the best qualities are not fixed in them. + +[Illustration: FIG. 250. HEAD OF A GALLOWAY COW] + +Moreover, it is possible for every farmer to determine exactly the +producing-power of his dairy cows. When the cows are milked, the milk +should be weighed and a record kept. If this be done, it will be found +that some cows produce as much as five hundred, and some as much as ten +hundred, gallons a year, while others produce not more than two or three +hundred gallons. If a farmer kills or sells his poor cows and keeps his +best ones, he will soon have a herd of only heavy milkers. Ask your +father to try this plan. Read everything you can find about taking care +of cows and improving them, and then start a herd of your own. + +=Conclusions.= (1) A cow with a tendency to get fat is not profitable +for the dairy. (2) A thin, open, angular cow will make expensive beef. +(3) "The sire is half the herd." This means that a good sire is +necessary to improve a herd of cattle. The improvement from scrubs +upward is as follows: the first generation is one-half pure; the second +is three-fourths pure; the third is seven-eighths pure; the fourth is +fifteen-sixteenths pure, etc. (4) By keeping a record of the quantity +and quality of milk each cow gives you can tell which are profitable to +raise from and which are not. (5) Good food, clean water, kindness, and +care are necessary to successful cattle-raising. + +[Illustration: FIG. 251. HOLSTEIN COW] + +The ownership of a well-bred animal usually arouses so much pride in the +owner that the animal receives all the care that it merits. The watchful +care given to such an animal leads to more thought of the other animals +on the farm, and often brings about the upbuilding of an entire herd. + + +SECTION LV. SHEEP + +The sheep was perhaps the first animal domesticated by man, and to-day +the domesticated sheep is found wherever man lives. It is found +domesticated or wild in almost every climate, and finds means to thrive +where other animals can scarcely live; it provides man with meat and +clothing, and is one of the most profitable and most easily cared-for of +animals. + +[Illustration: FIG. 252. A YOUNG SHEPHERD] + +Sheep increase so rapidly, mature at such an early age, and have flesh +so wholesome for food that nearly every farm should have its flock. +Another consideration that may be urged in favor of sheep-raising is +that sheep improve the land on which they are pastured. + +Sheep are docile and easily handled, and they live on a greater +diversity of food and require less grain than any other kind of live +stock. In mixed farming there is enough food wasted on most farms to +maintain a small flock of sheep. + +[Illustration: FIG. 253. SHEEP HAVE LONG BEEN CALLED THE +GOLDEN-HOOFED ANIMALS] + +Sheep may be divided into three classes: + + I. _Fine-Wooled Breeds_ + + 1. American Merino. + 2. Delaine Merino. + 3. Rambouillets. + 4. Hampshire Down. + 5. Oxford Down. + 6. Cheviot. + + II. _Medium-Wooled Breeds_ + + 1. Southdown. + 2. Shropshire. + 3. Horned Dorset. + + III. _Long-Wooled Breeds_ + + 1. Leicester. + 2. Lincoln. + 3. Cotswold. + +[Illustration: FIG. 254. IN THE PASTURE] + +The first group is grown principally for wool, and mutton is secondary; +in the second group, mutton comes first and wool second; in the third +group both are important considerations. Wool is nature's protection for +the sheep. Have you ever opened the fleece and observed the clean skin +in which the fibers grow? These fibers, or hairs, are so roughened that +they push all dirt away from the skin toward the outside of the fleece. + +Wool is valuable in proportion to the length and evenness of the fiber +and the density of the fleece. + + EXERCISE + + 1. How many pounds ought a fleece of wool to weigh? + 2. Which makes the better clothing, coarse or fine wool? + 3. Why are sheep washed before being sheared? + 4. Does cold weather trouble sheep? wet weather? + + + +SECTION LVI. SWINE + +The wild boar is a native of Europe, Asia, and Africa. The wild hogs are +the parents from which all our domestic breeds have sprung. In many +parts of the world the wild boar is still found. These animals are +active and powerful, and as they grow older are fierce and dangerous. In +their wild state they seek moist, sandy, and well-wooded places, close +to streams of water. Their favorite foods are fruits, grass, and roots, +but when pressed by hunger they will eat snakes, worms, and even higher +animals, like birds, fowls, and fish. + +[Illustration: FIG. 255. WHICH WILL YOU RAISE?] + +Man captured some of these wild animals, fed them abundant and +nutritious food, accustomed them to domestic life, selected the best of +them to raise from, and in the course of generations developed our +present breeds of hogs. The main changes brought about in hogs were +these: the legs became shorter, the snout and neck likewise shortened, +the shoulders and hams increased their power to take on flesh, and the +frame was strengthened to carry the added burden of flesh. As the animal +grew heavier it roamed less widely, and as it grew accustomed to man its +temper became less fierce. + +[Illustration: FIG. 256. A PAIR OF PORKERS] + +Meat can be more cheaply obtained from hogs than from any other animal. +When a hog is properly fed and cared for it will make the farmer more +money in proportion to cost than any other animal on the farm. + +The most profitable type of hog has short legs, small bones, straight +back and under line, heavy hams, small well-dished head, and heavy +shoulders. The scrub and "razorback" hogs are very unprofitable, and +require an undue amount of food to produce a pound of gain. It requires +two years to get the scrub to weigh what a well-bred pig will weigh +when nine months old. Scrub hogs can be quickly changed in form and type +by the use of a pure-bred sire. + +A boy whose parents were too poor to send him to college once decided to +make his own money and get an education. He bought a sow and began to +raise pigs. He earned the food for the mother and her pigs. His hogs +increased so rapidly that he had to work hard to keep them in food. By +saving the money he received from the sale of his hogs he had enough to +keep him two years in college. Suppose you try his plan, and let the hog +show you how fast it can make money. + +[Illustration: FIG. 257. A GOOD TYPE] + +We have several breeds of swine. The important ones are: + + I. _Large Breeds_ + + 1. Chester White. + 2. Improved Yorkshire. + 3. Tamworth. + + II. _Medium Breeds_ + + 1. Berkshire. + 2. Poland-China. + 3. Duroc-Jersey. + 4. Cheshire. + + III. _Small Breeds_ + + 1. Victoria. + 2. Suffolk. + 3. Essex. + 4. Small Yorkshire. + +Hogs will be most successfully raised when kept as little as possible in +pens. They like the fields and the pasture grass, the open air and the +sunshine. Almost any kind of food can be given them. Unlike other stock, +they will devour greedily and tirelessly the richest feeding-stuffs. + +The most desirable hog to raise is one that will produce a more or less +even mixture of fat and lean. Where only corn is fed, the body becomes +very fat and is not so desirable for food as when middlings, tankage, +cowpeas, or soy beans are added as a part of the ration. + +[Illustration: FIG. 258. DINNER IS OVER] + +When hogs are kept in pens, cleanliness is most important, for only by +cleanliness can disease be avoided. + + +SECTION LVII. FARM POULTRY + +Our geese, ducks, turkeys, and domestic hens are all descendants of wild +fowls, and are more or less similar to them in appearance. + +The earliest recorded uses of fowls were for food, for fighting, and for +sacrifice. To-day the domestic fowl has four well-defined +uses--egg-production, meat-production, feather-production, and +pest-destruction. + +[Illustration: STANDARD-BRED FOWLS +Barred Plymouth Rocks, male and female; White Wyandottes, female and +male] + +Hens of course produce most of our eggs. Some duck eggs are sold for +table use. Goose and duck body-feathers bring good prices. As +pest-destroyers turkeys and chickens are most useful. They eat large +numbers of bugs and worms that are harmful to crops. A little proper +attention would very largely increase the already handsome sum derived +from our fowls. They need dry, warm, well-lighted, and tidily kept +houses. They must have, if we want the best returns, an abundant supply +of pure water and a variety of nutritious foods. In cold, rainy, or +snowy weather they should have a sheltered yard, and in good weather +should be allowed a range wide enough to give them exercise. Their +bodies and their nests must be protected from every form of vermin. + +For eggs, the Leghorn varieties are popular. Some hens of this breed +have been known to lay more than two hundred eggs in a year. Specially +cared-for flocks have averaged eleven or even twelve dozen eggs a year. +Farm flocks of ordinary breeds average less than eight dozen. Other +excellent egg breeds are the Spanish, Andalusian, and Minorca. + +[Illustration: FIG. 259. COCK] + +The principal so-called meat breeds are the Brahma, Cochin, and +Langshan. These are very large, but rather slow-growing fowls, and are +not noted as layers. They are far less popular in America, even as +meat-producers, than the general-purpose breeds. + +The Plymouth Rock, Wyandotte, Rhode Island Red, and Orpington are the +leading general-purpose breeds. They are favorites because they are at +once good-sized, good layers, tame, and good mothers. The chicks of +these breeds are hardy and thrifty. In addition to these breeds, there +are many so-called fancy breeds that are prized for their looks rather +than for their value. Among these are the Hamburg, Polish, Sultan, +Silkie, and the many Bantam breeds. + +The leading duck breeds are the Pekin, Aylesbury, Indian Runner, +Muscovy, Rouen, and Cayuga. The principal varieties of geese are the +Toulouse, Emden, Chinese, and African. + +Among the best breeds of turkeys are the Bronze, White Holland, +Narragansett, Bourbon, Slate, and Buff. + +Geese, ducks, and turkeys are not so generally raised as hens, but there +is a constant demand at good prices for these fowls. + +[Illustration: FIG. 260. BROODER] + +The varieties of the domestic hen are as follows: + + I. _Egg Breeds_ + + 1. Leghorn. + 2. Minorca. + 3. Spanish. + 4. Blue Andalusian. + 5. Anconas. + + II. _Meat Breeds_ + + 1. Brahma. + 2. Cochin. + 3. Langshan. + 4. Dorking. + 5. Cornish. + + III. _General-Purpose Breeds_ + + 1. Plymouth Rock. + 2. Wyandotte. + 3. Rhode Island Red. + 4. Orpington. + + IV. _Fancy Breeds_ + + 1. Polish. + 2. Game. + 3. Sultan. + 4. Bantam. + +[Illustration: FIG. 261. BREEDING YARDS] + +[Illustration: FIG. 262. INCUBATOR] + +As the price of both eggs and fowls is steadily advancing, a great many +people are now raising fowls by means of an incubator for hatching, and +a brooder as a substitute for the mother hen. + +The use of the incubator is extending each year and is now almost +universal where any considerable number of chicks are to be hatched. +Doubtless it will continue to be used wherever poultry-production is +engaged in on a large scale. + +The brooder is employed to take care of the chickens as soon as they +leave the incubator. + + +SECTION LVIII. BEE CULTURE + +Stock-raisers select breeds that are best adapted to their needs. +Plant-growers exercise great care in their choice of plants, selecting +for each planting those best suited to the conditions under which they +are to be grown. Undoubtedly a larger yield of honey could be had each +year if similar care were exercised in the selection of the breed of +bees. + +[Illustration: FIG. 263. A CARNIOLAN WORKER] + +To prove this, one has only to compare the yield of two different kinds. +The common East Indian honey bee rarely produces more than ten or twelve +pounds to a hive, while the Cyprian bee, which is a most industrious +worker, has a record of one thousand pounds in one season from a single +colony. This bee, besides being industrious when honey material is +plentiful, is also very persevering when such material is hard to find. +The Cyprians have two other very desirable qualities. They stand the +cold of winter well and stoutly defend their hives against robber bees +and other enemies. + +The Italian is another good bee. This variety was brought into the +United States in 1860. While the yield from the Italian is somewhat less +than from the Cyprian, the Italian bees produce a whiter comb and are a +trifle more easily managed. + +The common black or brown bee is found wild and domesticated throughout +the country. When honey material is abundant, these bees equal the +Italians in honey-production, but when the season is poor, they fall far +short in the amount of honey produced. + +The purchase of a good Cyprian or Italian hive will richly repay the +buyer. Such a colony will cost more at the outset than an ordinary +colony, but will soon pay for its higher cost by greater production. + +[Illustration: FIG. 264. A CARNIOLAN DRONE] + +A beehive in the spring contains one queen, several hundred drones, and +from thirty-five to forty thousand workers. The duty of the queen is to +lay all the eggs that are to hatch the future bees. This she does with +untiring industry, often laying as many as four thousand in twenty-four +hours. + +The worker bees do all the work. Some of them visit the flowers, take up +the nectar into the honey-sac, located in their abdomens, and carry it +to the hive. They also gather pollen in basketlike cavities in their +hind legs. Pollen and nectar are needed to prepare food for the young +bees. In the hive other workers create a breeze by buzzing with their +wings and produce heat by their activity--all to cause the water to +evaporate from the nectar and to convert it into honey before it is +sealed up in the comb. After a successful day's gathering you may often +hear these tireless workers buzzing till late into the night or even all +through the night. + +You know that the bees get nectar from the flowers of various plants. +Some of the chief honey plants are alfalfa, buckwheat, horsemint, +sourwood, white sage, wild pennyroyal, black gum, holly, chestnut, +magnolia, and the tulip tree. The yield of honey may often be increased +by providing special pasturage for the bees. The linden tree, for +example, besides being ornamental and valuable for timber, produces a +most bee-inviting flower. Vetch, clover, and most of the legumes and +mints are valuable plants to furnish pasture for bees. Catnip may be +cultivated for the bees and sold as an herb as well. + +[Illustration: FIG. 265. A CARNIOLAN QUEEN] + +In spraying fruit trees to prevent disease you should always avoid +spraying when the trees are in bloom, since the poison of the spray +seriously endangers the lives of bees. + +The eggs laid by the queen, if they are to produce workers, require +about twenty-one days to bring forth the perfect bee. The newly hatched +bee commences life as a nurse. When about ten days old it begins to try +its wings in short flights, and a few days later it begins active work. +The life of a worker bee in the busy season is only about six weeks. You +may distinguish young exercising bees from real workers by the fact that +they do not fly directly away on emerging from the hive, but circle +around a bit in order to make sure that they can recognize home again, +since they would receive no cordial welcome if they should attempt to +enter another hive. They hesitate upon returning from even these short +flights, to make sure that they are in front of their own door. + +[Illustration: FIG. 266. GOOD FORM OF HIVE] + +There are several kinds of enemies of the bee which all beekeepers +should know. One of these is the robber bee, that is, a bee from another +colony attempting to steal honey from the rightful owners, an attempt +often resulting in frightful slaughter. Much robbery can be avoided by +clean handling; that is, by leaving no honey about to cultivate a taste +for stolen sweets. The bee moth is another serious enemy. The larva of +the moth feeds on the wax. Keep the colonies of bees strong so that they +may be able to overcome this moth. + +[Illustration: FIG. 267. ANTI-ROBBING ENTRANCE +_st_, stationary piece; _s_, slide; _p_, pin, or stop] + +Queenless or otherwise weak colonies should be protected by a narrow +entrance that admits only one bee at a time, for such a pass may be +easily guarded. Fig. 267 shows a good anti-robbery entrance which may be +readily provided for every weak colony. Mice may be kept out by +tin-lined entrances. The widespread fear of the kingbird seems +unfounded. He rarely eats anything but drones, and few of them. This is +also true of the swallow. Toads, lizards, and spiders are, however, true +enemies of the honeybee. + + EXERCISE + + Can you recognize drones, workers, and queens? Do bees usually + limit their visits to one kind of blossom on any one trip? What + effect has the kind of flower on the flavor of the honey produced? + What kinds of flowers should the beekeeper provide for his bees? Is + the kingbird really an enemy to the bee? + + +SECTION LIX. WHY WE FEED ANIMALS + +In the first place, we give various kinds of feed stuffs to our animals +that they may live. The heart beats all the time, the lungs contract and +expand, digestion is taking place, the blood circulates through the +body--something must supply force for these acts or the animal dies. +This force is derived from food. + +In the next place, food is required to keep the body warm. Food in this +respect is fuel, and acts in the same way that wood or coal does in the +stove. Our bodies are warm all the time, and they are kept warm by the +food we eat at mealtime. + +Then, in the third place, food is required to enable the body to +enlarge--to grow. If you feed a colt just enough to keep it alive and +warm, there will be no material present to enable it to grow; hence you +must add enough food to form bone and flesh and muscle and hair and fat. + +In the fourth place, we feed to produce strength for work. An animal +poorly fed cannot do so much work at the plow or on the road as one that +receives all the food needed. + +Both food and the force produced by it result from the activity of +plants. By means of sunlight and moisture a sprouting seed, taking out +of the air and soil different elements, grows into a plant. Then, just +as the plant feeds on the air and soil to get its growth, so the animal +feeds on the plant, to get its growth. Hence, since our animals feed +upon plants, we must find out what is in plants in order to know what +animal food consists of. + +Plants contain protein, carbohydrates, fat, mineral matter, water, and +vitamins. You have seen protein compounds like the white of an egg, lean +meat, or the gluten of wheat. The bodies of plants do not contain very +much protein. On the other hand, all plant seeds contain a good deal of +this substance. Animals make use of protein to form new blood, muscles, +and organs. Because of the quality of protein, milk is the best food for +children and young animals. + +The protein in some foods is of poor quality. To insure a well-balanced +supply of protein a variety in foods is desirable. Do not rely on a +single kind of mill feed, but combine several kinds, such as cotton-seed +meal, linseed meal, wheat bran and middlings, gluten, and similar grain +by-products. Tankage for young pigs and meat scraps for chickens are +high-grade proteins and are of animal origin. + +It is no less important to get the necessary vitamins--those mysterious +substances that keep the body healthy and promote growth and well-being. +Scientists claim that many diseases are food-deficiency diseases--the +body gets out of order because these peculiar vitamins are lacking in +the food. Children require about one or two quarts of milk a day, fresh +fruits, cereal breakfast foods, leafy vegetables as salads, and cooked +vegetables. + +Farm animals require the vitamins also. The legume pasture or hay, milk, +grain concentrates when supplied in variety, pasture grass, and green +forage crops are basic foods for farm animals. Very young animals should +have milk also. + +Let us next consider the carbohydrates. Sometimes the words _starchy +foods_ are used to describe the carbohydrates. You have long known +forms of these in the white material of corn and of potatoes. The +carbohydrates are formed of three elements--carbon, oxygen, and +hydrogen. The use of these carbohydrates is to furnish to animal bodies +either heat or energy or to enable them to store fat. + +In the next place, let us look at the fat in plant food. This consists +of the oil stored up in the seeds and other parts of the plant. The +grains contain most of the oil. Fat is used by the animal to make heat +and energy or to be stored away in the body. + +The next animal food in the plant that we are to think about is the +mineral matter. The ashes of a burnt plant furnish a common example of +this mineral matter. The animal uses this material of the plant to make +bone, teeth, and tissue. + +The last thing that the plant furnishes the animal is water--just common +water. Young plants contain comparatively large quantities of water. +This is one reason why they are soft, juicy, and palatable. But, since +animals get their water chiefly in another way, the water in feed stuffs +is not important. + + +WHAT THESE COMPOUNDS DO IN THE BODY + + _Protein_ + + 1. Forms flesh, bone, blood, internal organs, hair, and milk. + 2. May be used to make fat. + 3. May be used for heat. + 4. May be used to produce energy. + + _Carbohydrates_ + + 1. Furnish body heat. + 2. Furnish energy. + 3. Make fat. + + _Fat_ + + 1. Furnishes body heat. + 2. Furnishes energy. + 3. Furnishes body fat. + + _Mineral Matter_ + + Furnishes mineral matter for the bones in the body. + + _Water_ + + Supplies water in the body. + + + + +CHAPTER XI + +FARM DAIRYING + + +SECTION LX. THE DAIRY COW + +Success in dairy farming depends largely upon the proper feeding of +stock. There are two questions that the dairy farmer should always ask +himself: Am I feeding as cheaply as I can? and, Am I feeding the best +rations for milk and butter production? Of course cows can be kept alive +and in fairly good milk flow on many different kinds of food, but in +feeding, as in everything else, there is an ideal to be sought. + +[Illustration: FIG. 268. MILKING-TIME] + +What, then, is an ideal ration for a dairy cow? Before trying to answer +this question the word _ration_ needs to be explained. By ration is +meant a sufficient quantity of food to support properly an animal for +one day. If the animal is to have a proper ration, we must bear in mind +what the animal needs in order to be best nourished. To get material for +muscle, for blood, for milk, and for some other things, the animal +needs, in the first place, food that contains protein. To keep warm and +fat, the animal must, in the second place, have food containing +carbohydrates and fats. These foods must be mixed in right proportions. + +[Illustration: FIG. 269. A DAIRY] + +With these facts in mind we are prepared for an answer to the question, +What is an ideal ration? + +First, it is a ration that, without waste, furnishes both in weight and +bulk of dry matter a sufficient amount of digestible, nutritious food. + +Second, it is a ration that is comparatively cheap. + +Third, it is a ration in which the milk-forming food (protein) is +rightly proportioned to the heat-making and fat-making food +(carbohydrates and fat). Any ration in which this proportion is +neglected is badly balanced. + +Now test one or two commonly used rations by these rules. Would a ration +of cotton-seed meal and cotton-seed hulls be a model ration? No. Such a +ration, since the seeds are grown at home, would be cheap enough. +However, it is badly balanced, for it is too rich in protein; hence it +is a wasteful ration. Would a ration of corn meal and corn stover be a +desirable ration? This, too, since the corn is home-grown, would be +cheap for the farmer; but, like the other, it is badly balanced, for it +contains too much carbohydrate food and is therefore a wasteful ration. + +A badly balanced ration does harm in two ways: first, the milk flow of +the cow is lessened by such a ration; second, the cow does not +profitably use the food that she eats. + +The following table gives an excellent dairy ration for the farmer who +has a silo. If he does not have a silo, some other food can be used in +place of the ensilage. The table also shows what each food contains. As +you grow older, it will pay you to study such tables most carefully. + + + =============================================================== + | DIGESTIBLE MATTER + |---------------------------------- + FEED STUFFS | Dry |Protein|Carbohydrates| Fat + |matter| | | + --------------------------------------------------------------- + Cowpea hay = 15 pounds[1] | 13.50| 1.62 | 5.79 | .16 + Corn stover = 10 pounds | 5.95| .17 | 3.24 | .07 + Corn ensilage = 30 pounds | 6.27| .27 | 3.39 | .21 + Cotton-seed meal = 2 pounds | 1.83| .74 | .33 | .24 + --------------------------------------------------------------- + Total = 57 pounds | 27.55| 2.80 | 12.75 | .68 + =============================================================== + +[Footnote 1: Alfalfa or clover hay may take the place of cowpea hay.] + +=Care of the Cow.= As the cow is one of the best money-makers on the +farm, she should, for this reason, if for no other, be comfortably +housed, well fed and watered, and most kindly treated. In your thoughts +for her well-being, bear the following directions in mind: + +1. If you are not following a balanced ration, feed each day several +different kinds of food. In this way you will be least likely to waste +food. + +2. Feed at regular hours. Cows, like people, thrive best when their +lives are orderly. + +3. Milk at regular hours. + +4. Brush the udder carefully with a moist cloth before you begin to +milk. Cleanliness in handling makes the milk keep longer. + +5. Always milk in buckets or cups that have been scalded since the last +using. The hot water kills the bacteria that collect in the dents or +cracks of the utensil. + +6. Never let the milk pail remain in the stable. Milk rapidly absorbs +impurities. These spoil the flavor and cause the milk to sour. + +7. Never scold or strike the cow. She is a nervous animal, and rough +usage checks the milk flow. + +[Illustration] + +[Illustration: THREE GENERATIONS OF HIGH-BRED COWS] + + +SECTION LXI. MILK, CREAM, CHURNING, AND BUTTER + +=Milk.= Milk is, as you know, nature's first food for mammals. This is +because milk is a model food--it contains water to slake thirst, ash to +make bone, protein to make flesh and muscle, and fat and sugar to keep +the body warm and to furnish energy. + +=The Different Kinds of Milk.= Whole, or unskimmed, milk, skimmed milk, +and buttermilk are too familiar to need description. When a cow is just +fresh, her milk is called _colostrum_. Colostrum is rich in the very +food that the baby calf needs. After the calf is a few days old, +colostrum changes to what is commonly known as milk. + +The following table shows the composition of each of the different forms +of milk: + + ======================================================= + | DIGESTIBLE MATTER IN 100 POUNDS + |---------------------------------- + COMPOSITION OF MILK | Dry |Protein|Carbohydrates| Fat + |matter| | | + ------------------------------------------------------- + Colostrum | 25.4 | 17.6 | 2.7 | 3.6 + Milk (unskimmed) | 12.8 | 3.6 | 4.9 | 3.7 + Skimmed milk | 9.4 | 2.9 | 5.2 | 1.3 + Buttermilk | 9.9 | 3.9 | 4.0 | 1.1 + ======================================================= + +A noticeable fact in this table is that skimmed milk differs from +unskimmed mainly in the withdrawal of the fat. Hence, if calves are fed +on skimmed milk, they should have in addition some food like corn meal +to take the place of the fat withdrawn. A calf cannot thrive on skimmed +milk alone. The amount of nourishing fat that a calf gets out of enough +milk to make a pound of butter can be bought, in the form of linseed or +corn meal, for a very small amount, while the butter-fat costs, for +table use, a much larger sum. Of course, then, it is not economical to +allow calves to use unskimmed milk. Some people undervalue skimmed milk; +with the addition of some fatty food it makes an excellent ration for +calves, pigs, and fowls. + +Along with its dry matter, its protein, its carbohydrates, and its fats, +milk and its products possess another most important property. This +property is hard to describe, for its elements and its powers are not +yet fully understood. We do, however, know certainly this much: milk and +the foods made from it have power to promote health and favor growth in +a more marked degree than any other foods. It is generally agreed that +this is due to the health-promoting and health-preserving substances +which are called vitamines. Men of science are working with much care to +try to add to our knowledge of these vitamines, which have so marvelous +an influence on the health of all animals. Unless food, no matter how +good otherwise, contains these vitamines, it does not nourish the body +nor preserve bodily health as it should. A complete lack of vitamines in +our food would cause death. Since, then, milk and its products--butter, +cheese, curds--are rich in vitamines, these health-giving and +health-preserving foods should form a regular part of each person's +diet. + +[Illustration: FIG. 270. AIRING THE CANS] + +=Cream.= Cream is simply a mixture of butter-fat and milk. The +butter-fat floats in the milk in little globe-shaped bodies, or +globules. Since these globules are lighter than milk, they rise to the +surface. Skimming the milk is a mere gathering together of these +butter-fat globules. As most of the butter-fat is contained in the +cream, pains should be taken to get all the cream from the milk at +skimming time. + +After the cream has been collected, it must be allowed to "ripen" or to +"sour" in order that it may be more easily churned. Churning is only a +second step to collect in a compact shape the fat globules. It often +happens that at churning-time the cream is too warm for successful +separation of the globules. Whenever this is the case the cream must be +cooled. + +[Illustration: FIG. 271. A HAND SEPARATOR] + +=The Churn.= Revolving churns without inside fixtures are best. Hence, +in buying, select a barrel or a square box churn. This kind of churn +"brings the butter" by the falling of the cream from side to side as the +churn is revolved. Never fill the churn more than one-third or one-half +full of cream. A small churn is always to be avoided. + +=Churning.= The proper temperature for churning ranges from 58 deg. to 62 deg. +Fahrenheit. Test the cream when it is put into the churn. If it be too +cold, add warm water until the proper temperature is reached; if too +warm, add cold water or ice until the temperature is brought down to +62 deg.. Do not churn too long, for this spoils butter. As soon as the +granules of butter are somewhat smaller than grains of wheat, stop the +churn. Then draw off the buttermilk and at a temperature as low as 50 deg. +wash the butter in the churn. This washing with cold water so hardens +the granules that they do not mass too solidly and thus destroy the +grain. + +=Butter.= The butter so churned is now ready to be salted. Use good fine +dairy salt. Coarse barrel salt is not fit for butter. The salt can be +added while the butter is still in the churn or after it is put upon the +butter-worker. Never work by hand. The object of working is to get the +salt evenly distributed and to drive out some of the brine. It is +usually best to work butter twice. The two workings bring about a more +even mixture of the salt with the butter and drive off more water. But +one cannot be too particular not to overwork butter. Delicate coloring, +attractive stamping with the dairy owner's special stamp, and proper +covering with paper cost little and of course add to the ready and +profitable sale of butter. + +[Illustration: FIG. 272. A POWER CHURN] + + +DAIRY RULES + +_Stable and Cows_ + +1. Whitewash the stable once or twice each year; use land plaster, muck, +or loam daily in the manure-gutters. + +2. On their way to pasture or milking-place, do not allow the cows to be +driven at a faster gait than a comfortable walk. + +3. Give abundance of pure water. + +4. Do not change feed suddenly. + +5. Keep salt always within reach of each cow. + +_Milking_ + +1. Milk with dry hands. + +2. Never allow the milk to touch the milker's hands. + +3. Require the milker to be clean in person and dress. + +4. Milk quietly, quickly, thoroughly. Never leave a drop of milk in the +cow's udder. + +5. Do not allow cats, dogs, or other animals around at milking-time. + +_Utensils_ + +1. Use only tin or metal cans and pails. + +2. See that all utensils are thoroughly clean and free from rust. + +3. Require all cans and pails to be scalded immediately after they are +used. + +4. After milking, keep the utensils inverted in pure air, and sun them, +if possible, until they are wanted for use. + +5. Always sterilize the churn with steam or boiling water before and +after churning. This prevents any odors or bad flavors from affecting +the butter. All cans, pails, and bottles should also be sterilized +daily. + +[Illustration] + + +SECTION LXII. HOW MILK SOURS + +[Illustration: FIG. 273. MICROSCOPIC APPEARANCE OF PURE AND IMPURE MILK +At the left, pure milk; at the right, milk after standing in a warm room +for a few hours in a dirty dish, showing, besides the fat-globules, many +forms of bacteria] + +On another page you have been told how the yeast plant grows in cider +and causes it to sour, and how bacteria sometimes cause disease in +animals and plants. Now you must learn what these same living forms have +to do with the souring of milk, and maybe you will not forget how you +can prevent your milk from souring. In the first place, milk sours +because bacteria from the air fall into the milk, begin to grow, and +very shortly change the sugar of the milk to an acid. When this acid +becomes abundant, the milk begins to curdle. As you know, the bacteria +are in air, in water, and in barn dust; they stick on bits of hay and +stick to the cow. They are most plentiful, however, in milk that has +soured; hence, if we pour a little sour milk into a pail of fresh milk, +the fresh milk will sour very quickly, because we have, so to speak, +"seeded" or "planted" the fresh milk with the souring germs. No one, of +course, ever does this purposely in the dairy, yet people sometimes do +what amounts to the same thing--that is, put fresh milk into poorly +cleaned pails or pans, the cracks and corners of which are cozy homes +for millions of germs left from the last sour milk contained in the +vessel. It follows, then, that all utensils used in the dairy should be +thoroughly scalded so as to kill all germs present, and particular care +should be taken to clean the cracks and crevices, for in them the germs +lurk. + +In addition to this thorough cleansing with hot water, we should be +careful never to stir up the dust of the barn just before milking. Such +dusty work as pitching hay or stover or arranging bedding should be done +either after or long before milking-time, for more germs fall into the +milk if the air be full of dust. + +To further avoid germs the milker should wear clean overalls, should +have clean hands, and, above all, should never wet his hands with milk. +This last habit, in addition to being filthy, lessens the keeping power +of the milk. The milker should also moisten the parts of the cow which +are nearest him, so that dust from the cow's sides may not fall into the +milker's pail. For greater cleanliness and safety many milkmen curry +their cows. + +The first few streams from each teat should be thrown away, because the +teat at its mouth is filled with milk which, having been exposed to the +air, is full of germs, and will do much toward souring the other milk in +the pail. Barely a gill will be lost by throwing the first drawings +away, and this of the poorest milk too. The increase in the keeping +quality of the milk will much more than repay the small loss. If these +precautions are taken, the milk will keep several hours or even several +days longer than milk carelessly handled. By taking these steps to +prevent germs from falling into the milk, a can of milk was once kept +sweet for thirty-one days. + +The work of the germ in the dairy is not, however, confined to souring +the milk. Certain kinds of germs give to the different sorts of cheeses +their marked flavors and to butter its flavor. If the right germ is +present, cheese or butter gets a proper flavor. Sometimes undesirable +germs gain entrance and give flavors that we do not like. Such germs +produce cheese or butter diseases. "Bitter butter" is one of these +diseases. To keep out all unpleasant meddlers, thoroughly cleanse and +scald every utensil. + + EXERCISE + + What causes milk to sour? Why do unclean utensils affect the milk? + How should milk be cared for to prevent its souring? Prepare two + samples, one carefully, the other carelessly. Place them side by + side. Which keeps longer? Why? + + +SECTION LXIII. THE BABCOCK MILK-TESTER + +It is not sufficient for a farmer or a dairyman to know how much milk +each of his cows yields. He should also know how rich the milk is in +butter-fat. Wide-awake makers of butter and cheese now buy milk, not by +the pound or by the gallon, but by the amount of butter-fat contained in +each pound or gallon of milk. A gallon of milk containing four and a +half per cent of fat will consequently be worth more than a gallon +containing only three per cent of fat. So it may happen that a cow +giving only two gallons of milk may pay a butter-maker more than a cow +giving three gallons of milk. Of course it is easy to weigh or measure +the quantity of milk given by a cow, and most milkers keep this record; +but until recent years there was no way to find out the amount of fat in +a cow's milk except by a slow and costly chemical test. Dairymen could +only guess at the richness of milk. + +In 1890 Dr. S. M. Babcock of the Wisconsin Experiment Station invented a +wonderful little machine that quickly and cheaply measures the fat in +milk. Few machines are more useful. So desirous was Dr. Babcock of +helping the farmers that he would not add to the cost of his machine by +taking out a patent on his invention. His only reward has been the fame +won by the invention of the machine, which bears his name. This most +useful tester is now made in various sizes so that every handler of milk +may buy one suited to his needs and do his own testing at very little +cost. + +The operation of the machine is very simple. Suppose that the members of +the class studying this book have been asked to take a Babcock machine +and test the milk of a small herd of cows. They can readily do so by +following these directions: + +While the milk is still warm from the first cow to be tested, mix it +thoroughly by pouring it at least four times from one vessel to another. +A few ounces of this mixed milk is then taken for a sample, and +carefully marked with the name of the cow. A number is also put on the +sample, and both the cow's name and the number entered in a notebook. A +small glass instrument, called a pipette, comes with each machine. Put +one end of the pipette into the milk sample and the other end into the +mouth. Suck milk into the pipette until the milk comes up to the mark on +the side of the pipette. As soon as the mark is reached, withdraw the +pipette from the mouth and quickly press the forefinger on the mouth +end. The pressure of the finger will keep the milk from running out. +Then put the lower end of the pipette into one of the small long-necked +bottles of the machine, and, lifting the finger, allow the milk to flow +gently into the bottle. Expel all the milk by blowing through the +pipette. + +The next step is to add a strong, biting acid known as sulphuric acid to +the test-bottle into which you have just put the milk. A glass marked to +show just how much acid to use also comes with the machine. Fill this +glass measure to the mark. Then pour the acid carefully into the +test-bottle. Be sure not to drop any of the acid on your hands or your +clothes. As the acid is heavier than the milk, it will sink to the +bottom of the bottle. With a gentle whirling motion, shake the bottle +until the two fluids are thoroughly mixed. The mixture will turn a dark +brown and become very warm. + +Now fill the other bottles in the same way with samples drawn from +different cows. Treat all the samples precisely as you did the first. Do +not forget to put on each sample the name of the cow giving the milk and +on each test-bottle a number corresponding to the name of the cow. + +You are now ready to put the test-bottles in the sockets of the machine. +Arrange the bottles in the sockets so that the whirling frame of the +machine will be balanced. Fit the cover on the machine and turn the +handle slowly. Gradually gain in speed until the machine is whirled +rapidly. Continue the turning for about seven minutes at the speed +stated in the book of directions. + +After this first turning is finished, pour enough hot water into each +test-bottle to cause the fat to rise to the neck of the bottle. Re-cover +the machine and turn for one minute. Again add hot water to each bottle +until all the fat rises into the neck of the bottle and again turn one +minute. + +There remains now only the reading of the record. On the neck of each +bottle there are marks to measure the amount of fat. If the fat inside +the tube reaches only from the lowest mark to the second mark, then +there is only one per cent of fat in this cow's milk. This means that +the owner of the cow gets only one pound of butter-fat from each +hundred pounds of her milk. Such a cow would not be at all profitable to +a butter-seller. If the fat in another test-bottle reaches from the +lowest mark to the fourth mark, then you put in your record-book that +this cow's milk contains four per cent of butter-fat. This record shows +that the second cow's milk yields four pounds of fat to every hundred +pounds of milk. This cow is three times more valuable to a butter-maker +than the first cow. In the same way add one more per cent for each +higher mark reached by the fat. Four and one-half per cent is a good +record for a cow to make. Some cows yield as high as five or six per +cent but they do not generally keep up this record all the year. + +[Illustration: FIG. 274. BABCOCK TESTER AND HOW TO USE IT +The tester, acid, acid measure, test-bottle, and thermometer at bottom; +filling the pipette on right; adding the acid and measuring the fat at +top] + +The Babcock tester shows only the amount of pure butter-fat in the milk. +It does not tell the exact amount of finished butter which is made from +100 pounds of milk. This is because butter contains a few other things +in addition to pure butter-fat. Finished and salted butter weighs on an +average about one sixth more than the fat shown by the tester. Hence to +get the exact amount of butter in every 100 pounds of milk, you will +have to add one sixth to the record shown by the tester. Suppose, for +example, you took one sample from 600 pounds of milk and that your test +showed 4 per cent of fat in every 100 pounds of milk. Then, as you had +600 pounds of milk, you would have 24 pounds of butter-fat. This fat, +after it has been salted and after it has absorbed moisture as butter +does, will gain one sixth in weight. As one sixth of 24 is 4, this new 4 +pounds must be added to the weight of the butter-fat. Hence the 600 +pounds of milk would produce about 28 pounds of butter. + + EXERCISE + + 1. Find the number of pounds of butter in 1200 pounds of milk that + tests 3 per cent of butter-fat. + + 2. A cow yields 4800 pounds of milk in a year. Her milk tests 4 per + cent of butter-fat. Find the total amount of butter-fat she yields. + Find also the total amount of butter. + + 3. The milk of two cows was tested: one yielded in a year 6000 + pounds of milk that tested 3 per cent of fat; the other yielded + 5000 pounds that tested 4 per cent. Which cow yielded the more + butter-fat? What was the money value of the butter produced by each + if butter-fat is worth twenty-five cents a pound? + + + + +CHAPTER XII + +MISCELLANEOUS + + +SECTION LXIV. GROWING FEED STUFFS ON THE FARM + +Economy in raising live stock demands the production of all "roughness" +or roughage materials on the farm. By roughness, or roughage, of course +you understand that bulky food, like hay, grass, clover, stover, etc., +is meant. It is possible to purchase all roughage materials and yet make +a financial success of growing farm animals, but this certainly is not +the surest way to succeed. Every farm should raise all its feed stuffs. +In deciding what forage and grain crops to grow we should decide: + + 1. The crops best suited to our soil and climate. + 2. The crops best suited to our line of business. + 3. The crops that will give us the most protein. + 4. The crops that produce the most. + 5. The crops that will keep our soil in the best condition. + +1. _The crops best suited to our soil and climate._ Farm crops, as every +child of the farm knows, are not equally adapted to all soils and +climates. Cotton cannot be produced where the climate is cool and the +seasons short. Timothy and blue grass are most productive on cool, +limestone soils. Cowpeas demand warm, dry soils. But in spite of +climatic limitations, Nature has been generous in the wide variety of +forage she has given us. + +Our aim should be to make the best use of what we have, to improve by +selection and care those kinds best adapted to our soil and climate, and +to secure, by better methods of growing and curing, the greatest yields +at the least possible cost. + +2. _The crops best suited to our line of business._ A farmer necessarily +becomes more or less of a specialist; he gathers those kinds of live +stock about him which he likes best and which he finds the most +profitable. He should, on his farm, select for his main crops those that +he can grow with the greatest pleasure and with the greatest profit. + +[Illustration: FIG. 275. FILLING THE BARN WITH ROUGHAGE FROM THE FARM] + +The successful railroad manager determines by practical experience what +distances his engines and crews ought to run in a day, what coal is most +economical for his engines, what schedules best suit the needs of his +road, what trains pay him best. These and a thousand and one other +matters are settled by the special needs of his road. + +Ought the man who wants to make his farm pay be less prudent and less +far-sighted? Should not his past failures and his past triumphs decide +his future? If he be a dairy farmer, ought he not by practical tests to +settle for himself not only what crops are most at home on his land but +also what crops in his circumstances yield him the largest returns in +milk and butter? If swine-raising be his business, how long ought he to +guess what crop on his land yields him the greatest amount of hog food? +Should a colt be fed on one kind of forage when the land that produced +that forage would produce twice as much equally good forage of another +kind? All these questions the prudent farmer should answer promptly and +in the light of wise experiments. + +3. _The crops that will give us the most protein._ It is the farmer's +business to grow all the grass and forage that his farm animals need. He +ought never to be obliged to purchase a bale of forage. Moreover, he +should grow mainly those crops that are rich in protein materials, for +example, cowpeas, alfalfa, and clover. If such crops are produced on the +farm, there will be little need of buying so much cotton-seed meal, +corn, and bran for feeding purposes. + +4. _The crops that produce the most._ We often call a crop a crop +without considering how much it yields. This is a mistake. We ought to +grow, when we have choice of two crops, the one that is the best and the +most productive on the farm. Average corn, for instance, yields on an +acre at least twice the quantity of feeding-material that timothy does. + +5. _The crops that will keep our soil in the best condition._ A good +farmer should always be thinking of how to improve his soil. He wants +his land to support him and to maintain his children after he is dead. + +Since cowpeas, clover, and alfalfa add atmospheric nitrogen to the soil +and at the same time are the best feeding-materials, it follows that +these crops should hold an important place in every system of +crop-rotation. By proper rotating, by proper terracing, and by proper +drainage, land may be made to retain its fertility for generations. + + EXERCISE + + 1. Why are cowpeas, clover, and alfalfa so important to the farmer? + + 2. What is meant by the protein of a food? + + 3. Why is it better to feed the farm crops to animals on the farm + rather than to sell these crops? + + +SECTION LXV. FARM TOOLS AND MACHINES + +The drudgery of farm life is being lessened from year to year by the +invention or improvement of farm tools and machines. Perhaps some of you +know how tiresome was the old up-and-down churn dasher that has now +generally given place to the "quick-coming" churns. The toothed, +horse-drawn cultivator has nearly displaced "the man with the hoe," +while the scythe, slow and back-breaking, is everywhere getting out of +the way of the mowing-machine and the horserake. The old heavy, +sweat-drawing grain-cradle is slinking into the backwoods, and in its +place we have the horse-drawn or steam-drawn harvester that cuts and +binds the grain, and even threshes and measures it at one operation. +Instead of the plowman's wearily making one furrow at a time, the +gang-plows of the plains cut many furrows at one time, and instead of +walking the plowman rides. The shredder and husker turns the hitherto +useless cornstalk into food, and at the same time husks, or shucks, the +corn. + +The farmer of the future must know three things well: first, what +machines he can profitably use; second, how to manage these machines; +third, how to care for these machines. + +[Illustration: FIG. 276. PROPERLY PROTECTED TOOLS AND MACHINES] + +[Illustration: FIG. 277. UNPROTECTED TOOLS AND MACHINES] + +[Illustration: FIG. 278. THE HARVESTER AT WORK] + +[Illustration: FIG. 279. IN NEED OF IMPROVEMENT] + +The machinery that makes farming so much more economical and that makes +the farmer's life so much easier and more comfortable is too complicated +to be put into the hands of bunglers who will soon destroy it, and it is +too costly to be left in the fields or under trees to rust and rot. + +If it is not convenient for every farmer to have a separate tool-house, +he should at least set apart a room in his barn, or a shed for storing +his tools and machines. As soon as a plow, harrow, cultivator--indeed +any tool or machine--has finished its share of work for the season, it +should receive whatever attention it needs to prevent rusting, and +should be carefully housed. + +Such care, which is neither costly nor burdensome, will add many years +to the life of a machine. + + +SECTION LXVI. LIMING THE LAND + +Occasionally, when a cook puts too much vinegar in a salad, the dish +becomes so sour that it is unfit to eat. The vinegar which the cook uses +belongs to a large group of compounds known as acids. The acids are +common in nature. They have the power not only of making salads sour but +also of making land sour. Frequently land becomes so sour from acids +forming in it that it will not bear its usual crops. The acids must then +be removed or the land will become useless. + +The land may be soured in several ways. Whenever a large amount of +vegetable matter decays in land, acids are formed, and at times sourness +of the soil results. Often soils sour because they are not well drained +or because, from lack of proper tillage, air cannot make its way into +the soil. Sometimes all these causes may combine to produce sourness. +Since most crops cannot thrive on very sour soil, the farmer must find +some method of making his land sweet again. + +So far as we now know, liming the land is the cheapest and surest way of +overcoming the sourness. In addition to sweetening the soil by +overcoming the acids, lime aids the land in other ways: it quickens the +growth of helpful bacteria; it loosens stiff, heavy clay soils and +thereby fits them for easier tillage; it indirectly sets free the potash +and phosphoric acid so much needed by plants; and it increases the +capillarity of soils. + +However, too much must not be expected of lime. Often a farmer's yield +is so increased after he has scattered lime over his fields that he +thinks that lime alone will keep his land fertile. This belief explains +the saying, "Lime enriches the father but beggars the son." The +continued use of lime without other fertilization will indeed leave poor +land for the son. Lime is just as necessary to plant growth as the +potash and nitrogen and phosphoric acid about which we hear so much, but +it cannot take the place of these plant foods. Its duty is to aid, not +to displace them. + +We can tell by the taste when salads are too sour; it is more difficult +to find out whether land is sour. There are, however, some methods that +will help to determine the sourness of the soil. + +In the first place, if land is unusually sour, you can determine this +fact by a simple test. Buy a pennyworth of blue litmus paper from a drug +store. Mix some of the suspected soil with a little water and bury the +litmus paper in the mixture. If the paper turns red the soil is sour. + +In the second place, the leguminous crops are fond of lime. Clover and +vetch remove so much lime from the soil that they are often called lime +plants. If clover and vetch refuse to grow on land on which they +formerly flourished, it is generally, though not always, a sign that the +land needs lime. + +In the third place, when water grasses and certain weeds spring up on +land, that land is usually acid, and lime will be helpful. Moreover, +fields adjoining land on which cranberries, raspberries, blackberries, +or gallberries are growing wild, may always be suspected of more or less +sourness. + +Four forms of lime are used on land. These, each called by different +names, are as follows: + +First, quicklime, which is also called burnt lime, caustic lime, +builders' lime, rock lime, and unslaked lime. + +Second, air-slaked lime, which is also known as carbonate of lime, +agricultural lime, marl, and limestone. + +Third, water-slaked, or hydrated, lime. + +Fourth, land plaster, or gypsum. This form of lime is known to the +chemists as sulphate of lime. Do not forget that this last form is never +to be used on sour lands. We shall therefore not consider it further. + +Air-slaked lime is simply quicklime which has taken from the air a gas +called carbon dioxide. This is the same gas that you breathe out from +your lungs. + +Water-slaked lime is quicklime to which water has been added. In other +words, both of these are merely weakened forms of quicklime. One hundred +pounds of quicklime is equal in richness to 132 pounds of water-slaked +lime and to 178 pounds of air-slaked lime. These figures should be +remembered by a farmer when he is buying lime. If he can buy a fair +grade of quicklime delivered at his railway station for $5.00 a ton, he +cannot afford to pay more than $3.75 a ton for water-slaked lime, nor +more than $2.75 for air-slaked lime of equal grade. Quicklime should +always be slaked before it is applied to the soil. + +As a rule lime should be spread broadcast and then harrowed or disked +thoroughly into the soil. This is best done after the ground has been +plowed. For pastures or meadows air-slaked lime is used as a +top-dressing. When air-slaked lime is used it may be spread broadcast in +the spring; the other forms should be applied in the fall or in the +early winter. + + +SECTION LXVII. BIRDS + +What do birds do in the world? is an important question for us to think +about. First, we must gain by observation and by personal acquaintance +with the living birds a knowledge of their work and their way of doing +it. In getting this knowledge, let us also consider what we can do for +our birds to render their work as complete and effective as possible. + +Think of what the birds are doing on every farm, in every garden, and +about every home in the land. Think of the millions of beautiful wings, +of the graceful and attractive figures, of the cunning nests, and of the +singing throats! Do you think that the whole service of the birds is to +be beautiful, to sing charmingly, and to rear their little ones? By no +means is this their chief service to man. Aside from these services the +greatest work of birds is to destroy insects. It is one of the wise +provisions of nature that many of the most brilliantly winged and most +enchanting songsters are our most practical friends. + +Not all birds feed on insects and animals; but even those that eat but a +small amount of insect food may still destroy insects that would have +damaged fruit and crops much more than the birds themselves do. + +As to their food, birds are divided into three general classes. First, +those that live wholly or almost wholly on insects. These are called +insectivorous birds. Chief among these are the warblers, cuckoos, +swallows, martins, flycatchers, nighthawks, whippoorwills, swifts, and +humming-birds. We cannot have too many of these birds. They should be +encouraged and protected. They should be supplied with shelter and +water. + +Birds of the second class feed by preference on fruits, nuts, and grain. +The bluebird, robin, wood thrush, mocking-bird, catbird, chickadee, +cedar-bird, meadow lark, oriole, jay, crow, and woodpecker belong to +this group. These birds never fail to perform a service for us by +devouring many weed seeds. + +[Illustration: FIG. 280. A KINGBIRD] + +The third class is known as the hard-billed birds. It includes those +birds which live principally on seeds and grain--the canary, goldfinch, +sparrow, and some others. + +Birds that come early, like the bluebird, robin, and redwing, are of +special service in destroying insects before the insects lay their eggs +for the season. + +The robins on the lawn search out the caterpillars and cutworms. The +chipping sparrow and the wren in the shrubbery look out for all kinds of +insects. They watch over the orchard and feed freely on the enemies of +the apple and other fruit trees. The trunks of these trees are often +attacked by borers, which gnaw holes in the bark and wood, and often +cause the death of the trees. The woodpeckers hunt for these appetizing +borers and by means of their barbed tongues bring them from their +hiding-places. On the outside of the bark of the trunk and branches the +bark lice work. These are devoured by the nuthatches, creepers, and +chickadees. + +During the winter the bark is the hiding-place for hibernating insects, +which, like plant lice, feed in summer on the leaves. Throughout the +winter a single chickadee will destroy great numbers of the eggs of the +cankerworm moth and of the plant louse. The blackbirds, meadow larks, +crows, quail, and sparrows are the great protectors of the meadow and +field crops. These birds feed on the army worms and cutworms that do so +much injury to the young shoots; they also destroy the chinch bug and +the grasshopper, both of which feed on cultivated plants. + +[Illustration: FIG. 281. A WARBLER] + +A count of all the different kinds of animals shows that insects make up +nine tenths of them. Hence it is easy to see that if something did not +check their increase they would soon almost overrun the earth. Our +forests and orchards furnish homes and breeding-places for most of these +insects. Suppose the injurious insects were allowed to multiply +unchecked in the forests, their numbers would so increase that they +would invade our fields and create as much terror among the farmers as +they did in Pharaoh's Egypt. The birds are the only direct friends man +has to destroy these harmful insects. What benefactors, then, these +little feathered neighbors are! + +It has been estimated that a bird will devour thirty insects daily. Even +in a widely extended forest region a very few birds to the acre, if they +kept up this rate, would daily destroy many bushels of insects that +would play havoc with the neighboring orchards and fields. + +Do not imagine, however, that to destroy insects is the only use of +birds. The day is far more delightful when the birds sing, and when we +see them flit in and out, giving us a glimpse now and then of their +pretty coats and quaint ways. By giving them a home we can surround +ourselves with many birds, sweet of song and brilliant of plumage. + +[Illustration: FIG. 282. THE HAIRY WOODPECKER] + +If the birds felt that man were a friend and not a foe, they would often +turn to him for protection. During times of severe storm, extreme +drought, or scarcity of food, if the birds were sufficiently tamed to +come to man as their friend, as they do in rare cases now, a little food +and shelter might tide them over the hard time and their service +afterwards would repay the outlay a thousandfold. If the boys in your +families would build bird-houses about the house and barn and in shade +trees, they might save yearly a great number of birds. In building these +places of shelter and comfort, due care must be taken to keep them +clear of English sparrows and out of the reach of cats and bird-dogs. + +Whatever we do to attract the birds to make homes on the premises must +be done at the right time and in the right way. Think out carefully what +materials to provide for them. Bits of string, linen, cotton, yarn, tow +and other waste material, all help to induce a pair to build in the +garden. + +[Illustration: FIG. 283. PROTECTING OUR FRIENDS] + +It is an interesting study--the preparation of homes for the birds. +Trees may be pruned to make inviting crotches. A tangled, overgrown +corner in the garden will invite some birds to nest. + +Wrens, bluebirds, chickadees, martins, and some other varieties are all +glad to set up housekeeping in man-made houses. The proper size for a +bird-room is easily remembered. Give each room six square inches of +floor space and make it eight inches high. Old, weathered boards should +be used; or, if paint is employed, a dull color to resemble an old +tree-trunk will be most inviting. A single opening near the top should +be made two inches in diameter for the larger birds; but if the house is +to be headquarters for the wren, a one-inch opening is quite large +enough, and the small door serves all the better to keep out English +sparrows. + +The barn attic should be turned over to the swallows. Small holes may be +cut high up in the gables and left open during the time that the +swallows remain with us. They will more than pay for shelter by the good +work they do in ridding the barn of flies, gnats, and mosquitoes. + + +SECTION LXVIII. FARMING ON DRY LANDS + +Almost in the center of the western half of our continent there is a +vast area in which very little rain falls. This section includes nearly +three hundred million acres of land. It stretches from Canada on the +north into Texas on the south, and from the Missouri River (including +the Dakotas and western Minnesota) on the east to the Rocky Mountains on +the west. In this great area farming has to be done with little water. +This sort of farming is therefore called "dry-farming." + +The soil in this section is as a rule very fertile. Therefore the +difference between farming in this dry belt and farming in most of the +other sections of our country is a difference mainly due to a lack of +moisture. + +As water is so scarce in this region two things are of the utmost +importance: first, to save all the rain as it falls; second, to save all +the water after it has fallen. To save the falling rain it is necessary +for the ground to be in such a condition that none of the much-needed +rain may run off. Every drop should go into the soil. Hence the farmer +should never allow his top soil to harden into a crust. Such a crust +will keep the rain from sinking into the thirsty soil. Moreover the soil +should be deeply plowed. The deeper the soil the more water it can hold. +The land should also be kept as porous as possible, for water enters a +porous soil freely. The addition of humus in the form of vegetable +manures will keep the soil in the porous condition needed. Second, after +the water has entered the soil it is important to hold it there so that +it may supply the growing crops. If the land is allowed to remain +untilled after a rain or during a hot spell, the water in it will +evaporate too rapidly and thus the soil, like a well, will go dry too +soon. To prevent this the top soil should be stirred frequently with a +disk or smoothing harrow. This stirring will form a mulch of dry soil on +the surface, and this will hold the water. Other forms of mulch have +been suggested, but the soil mulch is the only practical one. It must be +borne in mind that this surface cultivation must be regularly kept up if +the moisture is to be retained. + +[Illustration: FIG. 284. THE DISK HARROW] + +Some experiments in wheat-growing have shown how readily water might be +saved if plowing were done at the right time. Wheat sowed on land that +was plowed as soon as the summer crops were taken off yielded a very +much larger return than wheat sowed on land that remained untilled for +some time after the summer crops were gathered. This difference in yield +on lands of the same fertility was due to the fact that the early +plowing enabled the land to take up a sufficient quantity of moisture. + +[Illustration: FIG. 285. RED KAFIR CORN IN SHOCK] + +In addition to a vigilant catching and saving of water, the farmer in +these dry climates must give his land the same careful attention that +lands in other regions need. The seed-bed should be most carefully +prepared. It should be deep, porous, and excellent in tilth. During the +growing season all crops should be frequently cultivated. The harrow, +the cultivator, and the plow should be kept busy. The soil should be +kept abundantly supplied with humus. + +Some crops need a little different management in dry-farming. Corn, for +example, does best when it is listed; that is, planted so that it will +come up three or four inches beneath the surface. If planted in this +way, it roots better, stands up better, and requires less work. + +Just as breeders study what animals are best for their climates, so +farmers in the dry belt should study what crops are best suited to their +lands. Some crops, like the sorghums and Kafir corn, are peculiarly at +home in scantily watered lands. Others do not thrive. Experience is the +only sure guide to the proper selection. + +To sum up, then, farmers can grow good crops in these lands only when +four things are done: first, the land must be thoroughly tilled so that +water can freely enter the soil; second, the land must be frequently +cultivated so that the water will be kept in the soil; third, the crops +must be properly rotated so as to use to best advantage the food and +water supply; fourth, humus must be freely supplied so as to keep the +soil in the best possible condition. + + +SECTION LXIX. IRRIGATION + +Irrigation is the name given to the plan of supplying water in large +quantities to growing crops. Since the dawn of history this practice has +been more or less followed in Asia, in Africa, and in Europe. The +Spanish settlers in the southwestern part of America were probably the +first to introduce this custom into our country. In New Mexico there is +an irrigating trench that has been in constant use for three hundred +years. + +[Illustration: FIG. 286. PUMPING WATER FOR IRRIGATION] + +The most common source of water for irrigating purposes is a river or a +smaller stream. Artesian wells are used in some parts of the country. +Windmills are sometimes used when only a small supply of water is +needed. Engines, hydraulic rams, and water-wheels are also employed. The +water-wheel is one of the oldest and one of the most useful methods of +raising water from streams. There are thousands of these in use in the +dry regions of the West. Small buckets are fastened to a large wheel, +which is turned by the current of a stream. As the wheel turns, the +buckets are filled, raised, and then emptied into a trough called a +flume. The water flows through the flume into the irrigating ditches, +which distribute it as it is needed in the fields. In some parts of +California and other comparatively dry sections, wells are sunk in or +near the beds of underground streams, and then the water is pumped into +ditches which convey it to the fields to be irrigated. + +Engines are often used for pumping water from streams and transferring +it to ditches or canals. The canals distribute the water over the land +or over the growing crops. + +[Illustration: FIG. 287. THE MAIN DITCH OF AN IRRIGATION PLANT] + +None of these methods, however, can be used for watering very large +areas of land. Hence, as the value of farm lands increased other methods +were sought. Shrewd men began to turn longing eyes on the wide stretches +of barren land in the West. They knew that these waste lands, seemingly +so unfertile, would become most fruitful as soon as water was turned on +them. Could water enough be found? New plans to pen up floods of water +were prepared, and immense sums were spent in carrying out these plans. +Enormous dams of cemented stone were thrown across the gorges in the +foothills of the mountains. Behind these solid dams the water from the +rains and the melting snow of the mountains was backed for miles, and +was at once ready to change barrenness into fruitfulness. The stored +water is led by means of main canals and cross ditches wherever it is +needed, and countless acres have been brought under cultivation. + +Water is generally applied either by making furrows for its passage +through the fields or by flooding the land. The latter plan is the +cheaper, but it can be used only on level lands. Where the land is +somewhat irregular a checking system, as it is called, is used to +distribute the water. It is taken from check to check until the entire +field has been irrigated. + +[Illustration: FIG. 288. THE PROCESS OF IRRIGATING CORN] + +The furrow method is usually employed for fruits and for farm and garden +crops. In many places the grass and grain crops are now supplied with +water by furrows instead of by flooding. + +Irrigated lands should be carefully and thoroughly tilled. The water for +irrigation is costly, and should be made to go as far as possible. Good +tillage saves the water. Moreover, all cultivated crops like corn, +potatoes, and orchard and truck crops ought to be cultivated frequently +to save the moisture, to keep the soil in fit condition, and to aid the +bacteria in the soil. It was a wise farmer who said, "One does not need +to grow crops many years in order to learn that nothing can take the +place of stirring the soil." + + +METHODS OF IRRIGATING CROPS + +_Tree fruits._ Water is conducted through very narrow furrows from three +to five feet apart, and allowed to sink about four feet deep, and to +spread under the ground. Then the supply is cut off. The object is to +wet the soil deeply, and then by tillage to hold the moisture in the +soil. + +_Small fruits._ The common practice is to run water on each side of the +row until the rows are soaked. + +_Potatoes._ A thorough soaking is given the land before planting-time, +and then no more than is absolutely necessary until blossoming-time. +After the blossoms appear keep the soil moist until the crop ripens. + +_Garden crops._ Any method may be employed, but the vital point is to +cultivate the ground as early as it can be worked after it has been +irrigated. + +_Meadows and alfalfa._ Flooding is the most common method in use. The +first irrigation comes early in the spring before growth has advanced +much, and the successive waterings after the harvesting of each crop. + + +SECTION LXX. LIFE IN THE COUNTRY + +As ours is a country in which the people rule, every boy and every girl +ought to be trained to take a wide-awake interest in public affairs. +This training cannot begin too early in life. A wise old man once said, +"In a republic you ought to begin to train a child for good citizenship +on the day of its birth." + +[Illustration: FIG. 289. BEAUTY FROM FLOWERS AND GRASS] + +[Illustration: FIG. 290. A COUNTRY ROAD IN MECKLENBURG COUNTY, +NORTH CAROLINA] + +Happy would it be for our nation if all the young people who live in the +country could begin their training in good citizenship by becoming +workers for these four things: + +First, attractive country homes. + +Second, attractive country schoolhouses and school grounds. + +Third, good country schools. + +Fourth, good roads. + +If the thousands on thousands of pupils in our schools would become +active workers for these things and continue their work through life, +then, in less than half a century, life in the country would be an +unending delight. + +One of the problems of our day is how to keep bright, thoughtful, +sociable, ambitious boys and girls contented on the farm. Every step +taken to make the country home more attractive, to make the school and +its grounds more enjoyable, to make the way easy to the homes of +neighbors, to school, to post-office, and to church, is a step taken +toward keeping on the farm the very boys and girls who are most apt to +succeed there. + +Not every man who lives in the country can have a showy or costly home, +but as long as grass and flowers and vines and trees grow, any man who +wishes can have an attractive house. Not every woman who is to spend a +lifetime at the head of a rural home can have a luxuriously furnished +home, but any woman who is willing to take a little trouble can have a +cozy, tastefully furnished home--a home fitted with the conveniences +that diminish household drudgery. Even in this day of cheap literature, +all parents cannot fill their children's home with papers, magazines, +and books, but by means of school and Sunday-school libraries, by means +of circulating book clubs, and by a little self-denial, earnest parents +can feed hungry minds just as they feed hungry bodies. + +[Illustration: THE QUEEN OF FLOWERS FOR THE HOME] + +[Illustration: FIG. 291. AN ATTRACTIVE COUNTRY HOME] + +Agricultural papers that arouse the interest and quicken the thought of +farm boys by discussing the best, easiest, and cheapest ways of farming; +journals full of dainty suggestions for household adornment and comfort; +illustrated papers and magazines that amuse and cheer every member of +the family; books that rest tired bodies and open and strengthen growing +minds--all of these are so cheap that the money reserved from the sale +of one hog will keep a family fairly supplied for a year. + +[Illustration: FIG. 292. AN UNIMPROVED SCHOOLHOUSE] + +[Illustration: FIG. 293. AN IMPROVED SCHOOLHOUSE] + +[Illustration: FIG. 294. THE SAME ROAD AFTER AND BEFORE IMPROVEMENT] + +If the parents, teachers, and pupils of a school join hands, an +unsightly, ill-furnished, ill-lighted, and ill-ventilated school-house +can at small cost be changed into one of comfort and beauty. In many +places pupils have persuaded their parents to form clubs to beautify the +school grounds. Each father sends a man or a man with a plow once or +twice a year to work a day on the grounds. Stumps are removed, trees +trimmed, drains put in, grass sowed, flowers, shrubbery, vines, and +trees planted, and the grounds tastefully laid off. Thus at scarcely +noticeable money cost a rough and unsightly school ground gives place to +a charming school yard. Cannot the pupils in every school in which this +book is studied get their parents to form such a club, and make their +school ground a silent teacher of neatness and beauty? + +[Illustration: FIG. 295. WASHINGTON'S COUNTRY HOME] + +Life in the country will never be as attractive as it ought to be until +all the roads are improved. Winter-washed roads, penning young people +in their own homes for many months each year and destroying so many of +the innocent pleasures of youth, build towns and cities out of the wreck +of country homes. Can young people who love their country and their +country homes engage in a nobler crusade than a crusade for improved +highways? + + + + +APPENDIX + + +SPRAYING MIXTURES + +FOR BITING INSECTS + +DRY PARIS GREEN + + Paris green 1 lb. + Lime or flour 4 to 16 lb. + +WET PARIS GREEN + + Paris green 1/4 to 2 lb. + Lime 1/4 to 1/2 lb. + Water 50 gal. + +FOR SOFT-BODIED SUCKING INSECTS + +KEROSENE EMULSION + + Hard soap (in fine shavings) 1/2 lb. + Soft water 1 gal. + Kerosene 2 gal. + +Dissolve soap in boiling water, add kerosene to the hot water, churn +with spraying pump for at least ten minutes, until the mixture changes +to a creamy, then to a soft, butterlike, mass. This gives three gallons +of 66-per-cent oil emulsion, which may be diluted to the strength +desired. To get 15-per-cent oil emulsion add ten and one-half gallons of +water. + +FOR FUNGOUS DISEASES + +COPPER SULPHATE + + Copper sulphate 1 lb. + Water 18 to 25 gal. + +Use only before foliage opens, to kill wintering spores. + +BORDEAUX MIXTURE + + Copper sulphate (bluestone) 4 to 5 lb. + Lime (good, unslaked) 5 to 6 lb. + Water 50 gal. + +Dissolve the copper sulphate (bluestone) in twenty-five gallons of +water. Slake the lime slowly so as to get a smooth, thick cream. Never +cover the lime with too much water. After thorough slaking add +twenty-five gallons of water. When the lime and the bluestone have +dissolved, pour the two liquids into a third vessel. Be sure that each +stream mixes with the other before either enters the vessel. Strain +through a coarse cloth. + +Mix fresh for each time. Use for molds and fungi generally. Apply in +fine spray with a good nozzle. + +BORDEAUX-PARIS-GREEN MIXTURE + + Ordinary Bordeaux mixture 50 gal. + Paris green 4 oz. to 2 lb. + +Use for both fungi and insects on apple, potato, etc. + +BORDEAUX-ARSENATE-OF-LEAD MIXTURE + + Ordinary Bordeaux mixture 50 gal. + Arsenate of lead 2 to 3 lb. + +Used for fungous and insect enemies of the potato, and of the apple when +bitter rot is troublesome. + +COMMERCIAL LIME-SULPHUR ARSENATE OF LEAD + + Commercial lime-sulphur 1-1/2 gal. + Arsenate of lead 2 to 3 lb. + Water 50 gal. + +Use for spraying apples. + +AMMONIACAL COPPER CARBONATE + + Copper carbonate 5 oz. + Ammonia (26 deg. Baume) about 3 pt. + Water 50 gal. + +Dissolve the copper carbonate in the smallest possible amount of +ammonia. This solution may be kept in stock and diluted to the proper +strength as needed. + +Use this instead of the Bordeaux mixture after the fruit has reached +half or two thirds of the mature size. It leaves no spots as does the +lime-sulphur wash or the Bordeaux mixture. + + +SPRAYS FOR BOTH FUNGOUS AND INSECT PESTS + +HOME-MADE LIME-SULPHUR WASH + + Lime 20 lb. + Sulphur 15 lb. + Water 50 gal. + +The lime, the sulphur, and about half of the water required are boiled +together for forty-five minutes in a kettle over a fire, or in a barrel +or other suitable tank by steam, strained, and then diluted to 50 +gallons. This is the wash regularly used against the San Jose scale. It +may be substituted for Bordeaux mixture when spraying trees in the +dormant state. Commercial lime-sulphur may also be used in place of this +homemade wash. Use one gallon of the commercial lime-sulphur to nine +gallons of water in the dormant season. + + +SELF-BOILED LIME-SULPHUR WASH + +The self-boiled lime-sulphur wash is a combination of lime and sulphur +boiled only by the heat of the slaking lime, and is used chiefly for +summer spraying on peaches, plums, cherries, etc. as a substitute for +the Bordeaux mixture. + + Lime 8 lb. + Sulphur 6 to 8 lb. + Water 50 gal. + +The lime should be placed in a barrel and enough water poured on it to +start it slaking and to keep the sulphur off the bottom of the barrel. +The sulphur, which should first be worked through a sieve to break up +the lumps, may then be added, and, finally, enough water to slake the +lime into a paste. Considerable stirring is necessary to prevent caking +on the bottom. After the violent boiling which accompanies the slaking +of the lime is over, the mixture should be diluted ready for use, or at +least enough cold water added to stop the cooking. From five to fifteen +minutes are required for the process. If the hot mass is permitted to +stand undiluted as a thick paste, a liquid is produced that is injurious +to peach foliage and, in some cases, to apple foliage. + +The mixture should be strained through a sieve of twenty meshes to the +inch in order to remove the coarse particles of lime, but all the +sulphur should be worked through the strainer. + + + + +GLOSSARY + + +To enable young readers to understand the technical words necessarily +used in the text only popular definitions are given. + + +=Abdomen=: the part of an insect lying behind the thorax. + +=Acid=: a chemical name given to many sour substances.

Project Gutenberg volunteers and employees expend considerable +effort to identify, do copyright research on, transcribe and proofread +public domain works in creating the Project Gutenberg-tm +collection. Despite these efforts, Project Gutenberg-tm electronic +works, and the medium on which they may be stored, may contain +"Defects," such as, but not limited to, incomplete, inaccurate or +corrupt data, transcription errors, a copyright or other intellectual +property infringement, a defective or damaged disk or other medium, a +computer virus, or computer codes that damage or cannot be read by +your equipment. + +1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right +of Replacement or Refund" described in paragraph 1.F.3, the Project +Gutenberg Literary Archive Foundation, the owner of the Project +Gutenberg-tm trademark, and any other party distributing a Project +Gutenberg-tm electronic work under this agreement, disclaim all +liability to you for damages, costs and expenses, including legal +fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT +LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE +PROVIDED IN PARAGRAPH F3. YOU AGREE THAT THE FOUNDATION, THE +TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE +LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR +INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH +DAMAGE. + +1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a +defect in this electronic work within 90 days of receiving it, you can +receive a refund of the money (if any) you paid for it by sending a +written explanation to the person you received the work from. If you +received the work on a physical medium, you must return the medium with +your written explanation. The person or entity that provided you with +the defective work may elect to provide a replacement copy in lieu of a +refund. If you received the work electronically, the person or entity +providing it to you may choose to give you a second opportunity to +receive the work electronically in lieu of a refund. If the second copy +is also defective, you may demand a refund in writing without further +opportunities to fix the problem. + +1.F.4. Except for the limited right of replacement or refund set forth +in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER +WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO +WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE. + +1.F.5. Some states do not allow disclaimers of certain implied +warranties or the exclusion or limitation of certain types of damages. +If any disclaimer or limitation set forth in this agreement violates the +law of the state applicable to this agreement, the agreement shall be +interpreted to make the maximum disclaimer or limitation permitted by +the applicable state law. The invalidity or unenforceability of any +provision of this agreement shall not void the remaining provisions. + +1.F.6.

Information about the Mission of Project Gutenberg-tm + +Project Gutenberg-tm is synonymous with the free distribution of +electronic works in formats readable by the widest variety of computers +including obsolete, old, middle-aged and new computers. It exists +because of the efforts of hundreds of volunteers and donations from +people in all walks of life. + +Volunteers and financial support to provide volunteers with the +assistance they need, is critical to reaching Project Gutenberg-tm's +goals and ensuring that the Project Gutenberg-tm collection will +remain freely available for generations to come. In 2001, the Project +Gutenberg Literary Archive Foundation was created to provide a secure +and permanent future for Project Gutenberg-tm and future generations. +To learn more about the Project Gutenberg Literary Archive Foundation +and how your efforts and donations can help, see Sections 3 and 4 +and the Foundation web page at http://www.pglaf.org. + + +Section 3. Information about the Project Gutenberg Literary Archive +Foundation + +The Project Gutenberg Literary Archive Foundation is a non profit +501(c)(3) educational corporation organized under the laws of the +state of Mississippi and granted tax exempt status by the Internal +Revenue Service. The Foundation's EIN or federal tax identification +number is 64-6221541. Its 501(c)(3) letter is posted at +http://pglaf.org/fundraising. Contributions to the Project Gutenberg +Literary Archive Foundation are tax deductible to the full extent +permitted by U.S. federal laws and your state's laws. + +The Foundation's principal office is located at 4557 Melan Dr. S. +Fairbanks, AK, 99712., but its volunteers and employees are scattered +throughout numerous locations. Its business office is located at +809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email +business@pglaf.org.

Newby + Chief Executive and Director + gbnewby@pglaf.org + + +Section 4. Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg-tm depends upon and cannot survive without wide +spread public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To +SEND DONATIONS or determine the status of compliance for any +particular state visit http://pglaf.org + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg Web pages for current donation +methods and addresses. Donations are accepted in a number of other +ways including checks, online payments and credit card donations. +To donate, please visit: http://pglaf.org/donate + + +Section 5. General Information About Project Gutenberg-tm electronic +works. + +Professor Michael S. Hart is the originator of the Project Gutenberg-tm +concept of a library of electronic works that could be freely shared +with anyone. For thirty years, he produced and distributed Project +Gutenberg-tm eBooks with only a loose network of volunteer support. + + +Project Gutenberg-tm eBooks are often created from several printed +editions, all of which are confirmed as Public Domain in the U.S. +unless a copyright notice is included. Thus, we do not necessarily +keep eBooks in compliance with any particular paper edition. + + +Most people start at our Web site which has the main PG search facility: + + http://www.gutenberg.org + +This Web site includes information about Project Gutenberg-tm, +including how to make donations to the Project Gutenberg Literary +Archive Foundation, how to help produce our new eBooks, and how to +subscribe to our email newsletter to hear about new eBooks. diff --git a/20772.zip b/20772.zip Binary files differnew file mode 100644 index 0000000..dd5e819 --- /dev/null +++ b/20772.zip diff --git a/LICENSE.txt b/LICENSE.txt new file mode 100644 index 0000000..6312041 --- /dev/null +++ b/LICENSE.txt @@ -0,0 +1,11 @@ +This eBook, including all associated images, markup, improvements, +metadata, and any other content or labor, has been confirmed to be +in the PUBLIC DOMAIN IN THE UNITED STATES. + +Procedures for determining public domain status are described in +the "Copyright How-To" at https://www.gutenberg.org. + +No investigation has been made concerning possible copyrights in +jurisdictions other than the United States.
