Walter S. Tomlinson, Bryan, Ohio, began thirteen years ago with 225 acres, partly rented, to determine whether a farm could be made a satisfying enterprise. As tenant he has paid to himself as landlord $1,000 each year for rental and $500 each year as salary. The rest of the profits have been invested in 240 acres of additional land and in improvements. Mr. Tomlinsons specialty has been hogs, but he says it does not matter so much about the lines one adopts as the attention that is given them.

Dr. W. I. Chamberlain, Hudson, Ohio, graduate of Western Reserve University, former state secretary of agriculture, later college president. Farmer and institute lecturer and widely known for his editorial work on farm journals; has been able, amid his other activities, to manage his farm of 116 acres. The net cash income above all expenses from the farm for 1890 to 1907 was $113,966 or $1,370 per year. Of this income $8,877 were obtained from a ten-acre apple orchard.

There will still remain the question of the present condition of the land. For example, the Pennsylvania station obtained in a certain season 42 loads of hay from nine acres of land. The same season, from exactly the same soil type, the station obtained eight loads of hay from 20 acres. The condition of the soil was different, which the previous history of the two tracts of land fully explains.
It is of the utmost importance, therefore,to distinguish between the natural fertility of the soil and the condition of the soil. A further example will help to illustrate this point. At the Rothamsted Station a certain type of soil has for over 60 years produced annually about 12 bushels of wheat an acre without fertilizer, while with a complete fertilizer the same type has produced 30 or more bushels. The 12 bushels may be said to represent the natural fertility of the soil, while the additional 18 bushels may be said to represent the condition of the soil due to fertilizers or to other conditions. On the other hand, the natural condition of some other soil type might be only eight bushels, or still another type might be 16 bushels.
This principle is of considerable practical importance, especially in the eastern third of the United States. Generally speaking, clay and silt soils have a greater natural fertility than sandy soils; limestone soils than those that are deficient in lime. Thus soils that naturally grow chestnut trees, indicating a low lime content, have a tendencyto deteriorate under exhaustive cropping much more rapidly than limestone soils. More fertilizers and other methods of soil improvement are necessary in the case of chestnut soils than in the case of limestone valley soils. One of the first questions to ask, therefore, concerning an unknown farm in Pennsylvania is whether or not chestnut trees grow naturally. It does not follow, however, that chestnut soils are undesirable. Much will depend upon the crop or crops it is desired to raise. For example, in some regions they are well adapted to potatoes and peaches. In these cases the cost of the fertilizers necessary to keep the soil in proper condition is small compared with the total return from the crop.
The pioneers best guide as to the value of new land was and is the vegetation growing upon it, and, especially in a wooded country, the native trees. Basswood, crab apple, wild plum, black walnut, ash, hickory and hard maple generally indicate a fertile soil. White oak indicates only a moderate soil;bur oak, a somewhat warmer and better drained soil. Beech indicates a rather poor soil; a heavy clay, lacking in organic matter. Certain species of elms, maples and oaks, as red maple and the Spanish swamp oak, indicate wet soils.
The occurrence and vigor of certain herbaceous plants are especially indicative of fertility of the soil, as, for example, ragweed, bindweed, certain plants of the sunflower family, such as goldenrod, asters and wild sunflowers. Soils adapted to red clover and alfalfa are usually well drained and contain plenty of lime. Alsike clover will grow on a soil too wet or containing too little lime for either of the former. Soils that produce sorrel and redtop when red clover and timothy are sown need drainage or liming or both. Sedges usually indicate a wet soil, although certain species grow on dry, sandy soils. The point of this paragraph, however, is not to give comprehensive advice but to cause the young farmer to observe the conditions and make his own applications, which will vary in differentregions and under different circumstances.
Perhaps the one feature that the young farmer is most likely to overlook in the selection of a farm is the relative proportion of tillable land. One farm of 200 acres, may, on account of stony land, wet land, comparatively unproductive woodland, or because of the arrangement of fences and roadways, contain only eighty acres of tillable land, while another may contain 160 acres. This is one reason why a 160-acre farm in the central West may be more valuable than a farm of the same size in the northeastern United States.
Columella says with regard to the selection of land that there are two things chiefly to be considered, the wholesomeness of the air and the fruitfulness of the place, of which if either the one or the other should be wanting, and notwithstanding anyone should have a mind to dwell there, he must have lost his senses and ought to be conveyed to his kinfolk to take care of him.
In selecting a farm do not fail to inquire whether there has been any recent illness,and if so the nature of it, either among the persons living there or the domestic animals kept.
Aside from healthfulness, climate is a fundamental and controlling factor, both in productiveness and economic farm management. Temperature and rainfall affect the number of days that work can be performed upon the land and hence affect materially the economy of labor. It is this fact that prevents the systematic organization of labor so common in manufacturing and transportation. The climate also affects the cost of producing live stock by modifying the food and shelter required.
The climate of a region is best studied from the reports of the United States Weather Bureau rather than from the statements published by interested parties. So far as the production of crops is concerned the distribution of rainfall is more important than the annual amount, as may be shown by comparing the rainfall in such places as Columbus, Ohio, and Lincoln, Nebraska.
The average temperature during the growing season is, of course, of more importance from the standpoint of crop production than the average annual temperature. Maximum and minimum temperatures or the range of temperature must be considered as well as the average temperature.
One of the most practical questions to determine is the average date of the last killing frost in the spring and the date of the first killing frost in the autumn; in other words, the length of the growing season. Both altitude and topography enter into this problem. In a given locality killing frosts will occur on a still night in the valley before they do on the elevations, because the air as it cools becomes heavier and flows down into the lowest places just as water would do. On the other hand, as the altitude increases the growing season shortens.
Whenever I am asked a question involving the production of farm crops by a Pennsylvania farmer before answering, I ask three questions: (1) Where are you located? (2) Do chestnut trees grow naturallyupon your land? (3) What is your altitude?
One factor that is often overlooked by the young farmer needs only to be mentioned to be thoroughly appreciated. It is the amount and character of the water supply. Not only is this of the utmost importance from the standpoint of the household, but it is fundamental to the best farm management. Thus, if the water supply is limited the amount of live stock kept will be curtailed, and thus the proper utilization of farm products prevented and maintenance of the fertility of the soil made more difficult.
The young farmer should recognize that some kinds of farming are more dependent upon the climatic conditions than others and should, therefore, select the location best suited to the type of farming desired or else modify his type of farming to suit the climatic conditions. If one studies critically the types of farming in various parts of the United States, it will be seen that they have already been adjusted in large degree,either consciously or unconsciously, to the climatic conditions. The young farmer should be careful that he does not undertake to butt his head against a stone wall.
Having found a farm that suits our ideal as to the natural conditions, such as the crop adaptation, fertility, topography and climate, what may be called the artificial conditions must be studied.
The location may be studied, both as to local and distant markets and the means of reaching each, which includes roadways and shipping facilities. Here again much will depend upon the products which are to be sold. The man who raises tobacco, hogs or beef cattle does not suffer any great economic disadvantage by living ten miles from a shipping station, but a man does who produces milk, peaches, potatoes or hay.
In these days there is not much danger that the character of the roadway will be overlooked by the intending purchaser of the farm, although sufficient importance may not be given to the advantage of really good roads, both as to grade and surface.Perhaps the one most important question to consider in connection with the transportation facilities is whether products may be shipped without change from the shipping station to the market it is desired to reach.
Although at first glance we may not like the thought, it must be conceded that neighbors are not only important morally and socially, but they also may have economic advantages and disadvantages. While it may sometimes happen that it will be wise to raise in a given neighborhood some product that no one else has undertaken to supply, yet as a rule, if a given neighborhood is raising Jersey, or Guernsey or Holstein cattle or Chester White, Berkshire or Poland China hogs, or Southdown or Shropshire or Cotswold sheep, it will be wise to raise the breed commonly raised instead of the least commonly raised breed, as it is sometimes supposed. The more potato growers or cabbage growers or celery raisers or orchardists in a locality the better for all concerned, for a number of reasons, among which may be mentioned (1) themore and the better the products raised the more buyers will seek the region and hence the higher will be the price obtained for the product; (2) the more of a given product there is to ship the better the shipping facilities for that product are likely to be; (3) all the necessary supplies for the type of farming can be more readily and cheaply obtained; (4) there will be a better knowledge of the business when more men have had experience in raising the particular crop.
These principles apply in all classes of business; thus we find woolen factories in Philadelphia, silk factories at Paterson, N. J., cotton factories at Lowell, Mass., plow factories at Moline, Ill., and steel mills at Pittsburg. Many of these centers possessed originally some natural advantages which caused the location of the first factory, but others have been drawn there on account of the principles enunciated. The farmers of a given region have a community of interest as well as railroads. The young farmer should recognize this fact and if necessaryshould exert himself to develop such interest in his community, both for his own benefit and that of his neighbors.
There are two classes of farms for which the purchaser is in danger of paying too much, one on which there are extensive improvements and one on which there are none at all. A farm with just barely enough improvements for the conduct of the type of farming it is proposed to develop can usually be purchased most advantageously. The purchaser should understand clearly that the previous cost of the improvements has no necessary relation to their present value, any more than the value of a second-hand suit of clothes is dependent upon its original cost. All depends on how badly they are worn and how well they are adapted to present conditions. The value of farm improvements is not unlike those in other business enterprises in this respect. Their value depends upon present and prospective earning capacity and not on former cost.
No rule can be laid down as to the relationwhich should exist between the value of land itself and the value of the improvements. In practice it varies greatly. In the United States the farm improvements constitute on an average 21% of the total value of land, being as high as 45% in Massachusetts and as low as 15% in Texas. The young farmer may well consider, therefore, whether he can earn interest on his investment when the improvements cost more than 25% of the total value of the real estate. Certainly when it becomes one-half it is excessive. The man who runs a farm as an avocation usually errs in putting too much money into permanent improvements for the farm to be a paying investment.
If it is admitted that the farm unit is limited because of the physical difficulties of managing large areas, then it must at once be seen how important the arrangement of the farmsteading must be to the successful conduct of the farm. In the older farming communities where the present farm holdings are the result of several purchases or sales the shape of the farm, the arrangementof the fields and the place of the farm buildings become an extremely important matter. Sometimes satisfactory rearrangements are easily made, at other times they are quite impossible. No attempt will be made to discuss this subject in detail here, but the young farmer should bring to this question all the experience and study possible.
When the young farmer goes to inspect a farm it is to be assumed that he will be conducted over the farm by the owner or his authorized agent. It is proper to give respectful attention to everything that is told him, provided he follows carefully the California adage to believe nothing you hear and only one-half what you see.
If a farm consists of 200 or 300 acres of land, it is possible for the agent to convey the purchaser over the farm in such a way as to prevent the least desirable portions being seen. If the farm has attracted the seeker of land, he should not purchase until he has made another visit, preferably some days or weeks after the first one. He may then very properly visit the farm alone, passingover quite a different course from that pursued hitherto. Sketches and notes will be found very helpful, and if the use of the soil auger is understood it may be well employed to study the character of both soil and subsoil. During the interval between visits some casual inquiries may be made among those who know the history of the farm in question, because the past history of the farm obtained from unprejudiced witnesses is of prime importance in arriving at a conclusion concerning its value.
A farm is much more attractive when a crop is growing upon it than when it is without active vegetation. Poor land looks relatively better than good land during or just after a rain. Many matters concerning the selection of a farm can only be learned by some years of practical experience. The young farmer will do well, therefore, to secure the help of some more experienced person. If he has among his acquaintances a successful farmer of mature years he will be fortunate if he can secure his advice.
CHAPTER VIIITHE FARM SCHEME
Farming is no pink tea. It is a serious business. After the young farmer has selected the farm he must develop his farm scheme. He must contemplate well and seriously the philosophy which underlies his plans. Unless he sees clearly what he is striving to attain and unless he understands the effect of his methods, he must fail in great measure to obtain his goal.
Satisfactory results in farming cannot be obtained as a general practice if the man is only interested in the results of a single year. For this reason the itinerant tenant system will not be satisfactory unless the landlord has worked out a satisfactory scheme which he requires his tenant to follow.
It is not enough that a man shall grow a single large crop, but it is necessary that he should continue to grow a satisfactory crop at least at regular intervals. For example, a piece of land may be adapted to cabbage,celery, potatoes or hay. Assume for the moment it is adapted to cabbage and that by one or more seasons of preparation an enormous crop of cabbages may be secured. This fact is of little value unless sufficient quantity is raised and the process can be repeated annually. Cabbages cannot be grown again on this particular piece of land for from four to six years on account of club root. If the farmer does not have other areas which he can bring into cabbages year after year, for from three to five years, then he becomes a failure as a cabbage raiser. Even a perennial, like alfalfa or asparagus, should form a part of the general scheme of crop production if the most satisfactory results are to be obtained.
There are two general questions at the basis of all farm schemes: (1) How to obtain a fairly uniform succession of cash products year after year, and (2) how to keep up or improve the fertility of the soil economically while doing so. In other words, how to keep the investment fromdecreasing while it is earning a satisfactory and fairly uniform income.
It is necessary, therefore, to consider what products are to be sold and what are simply subsidiary to the cash products. The cash products may, of course, be soil products or animal products, but more likely they will be both. When animals form a large part of the enterprise the cropping system must be carefully adjusted to meet the needs of these animals. Many apparently trivial details must be considered, as for example, whether the cropping system furnishes too little or too much bedding for the live stock.
In considering profits the enterprise as a whole must be kept in view. For example, if a man is producing milk, it may be cheaper, so far as the production of milk is concerned, to allow the liquid excrement to run to waste rather than to arrange for sufficient bedding. If, however, by using an abundance of bedding and saving all the high-priced nitrogen and the larger part of the potash in the manure, he is able to raise twelve tons of silage in place of eight tons,or three tons of hay in place of two tons, his enterprise as a whole will be more profitable when he uses the extra amount of bedding, although so far as the production of a quart of milk is concerned the cost is increased. It may be that by feeding corn to cattle or sheep one will obtain only 50 cents a bushel for his maize, while his neighbor is selling it to the elevator at 60 cents. If, however, the man who feeds his maize year after year thereby raises 60 bushels instead of 40 bushels, his enterprise, as a whole, may be more profitable than that of his neighbor.
As a matter of fact, the Pennsylvania experiment station has substantially these two conditions in certain of its fertilizer plats. When for 25 years the conditions have been similar to those where crops are sold from the farm, the yields have been: Maize, 42 bushels; oats, 32 bushels; wheat, 14 bushels; and hay, 2,783 pounds per acre. But when conditions exist which represent the feeding of corn, oats and hay and the return of manure to the soil, the yields have been: Maize, 58 bushels; oats, 41 bushels; wheat,23 bushels; and hay 4,190 pounds per acre. In the first instance the value of the products has been $15.75 an acre, while in the other case it has been $22.90 an acre.
Having worked out a cropping system that gives the proper yearly production of several crops desired, the next question to decide is how this cropping system and the disposition of the crops is going to affect the fertility of the soil. From a financial or economic point of view the most important soil element is nitrogen. First, because it costs from 18 to 20 cents a pound, while phosphoric acid can be purchased at five cents, potash at four cents; and, second, because of the readiness with which nitrogen may disappear from the soil under improper management, either through nitrification and leaching or by denitrification and passing back into the air.
Assuming a given type of management, the question is, How much of the required nitrogen will be obtained from the legumes in the cropping system, how much from the manure, and how much must be purchasedin commercial fertilizers? No satisfactory cropping system can be devised at the present prices of farm products and cost of fertilizers for the production of the ordinary cereals and hay that does not include the production of some legume. Assuming a legume in the cropping scheme, the fertility of the soil may be maintained by yard manure alone or by commercial fertilizers alone. Illustrations of both methods are to be found in actual practice. Generally speaking, however, the use of yard manure supplemented with commercial fertilizers will be found more scientific and in the end the most economical.
A factor entering into this problem will be the amount of purchased feed. If considerable amounts of purchased feeds are used and the resulting manure carefully preserved and judiciously applied, the commercial fertilizers required will be reduced to the minimum.
A concrete illustration may bring out the philosophy underlying farm schemes better than abstract problems.
The following outline shows a five-course rotation with the method of fertilization which the results of the Pennsylvania Station indicated would be advisable, at least on limestone soils in eastern United States.
This rotation is suggested for the purpose of maintaining a farm that is already in a fairly fertile condition and one on which there is no considerable amount of purchased feed. Where concentrates are purchased liberally, yard manure should be available to use on the timothy and meadow in place of the commercial fertilizers.
Where there is plenty of manure and it is desired to increase the amount of maize and hay and reduce the amount of oats and wheat, the following rotation and method of fertilization would be indicated:
Where there is plenty of yard manure, it would be also applied to maize under No. 1, or the yard manure could be applied to maize under No. 1, and commercial fertilizer applied to timothy under No. 6 could be repeated under No. 7. If the land is more or less depleted, an application of 200 pounds of acid phosphate to the oats would be advisable. However, the purpose is not to prescribe exact methods, but to point out underlying principles and their possible application.
As further illustration, it seems probable that the practice of a market gardener in using excessive amounts of stable manure might, in some instances at least, be modified to good advantage by reducing the amount of manure and increasing theamount of commercial fertilizer used. Unfortunately there is no experimental evidence bearing upon this question.
Potash required to maintain fertility is largely to be found in the coarse fodder, such as hay, maize stover and silage, and in the straw used for bedding; hence where these substances are used in abundance and returned to the soil the amount of potash required to be supplied in fertilizers is reduced to a minimum. Where, however, the amount of live stock is limited and the products sold contain large quantities of potash, such as hay and straw, the supply furnished in fertilizers must be liberal.
Phosphoric acid is always being slowly depleted from the soil either from the sale of farm crops or animal products. There is no way of returning this loss completely, except from the addition of a commercial fertilizer.
The above fertilizer suggestions are based on the experiments covering a period of more than 25 years on a limestone soil. Soils may modify materially the amountand application of the fertilizers, but not the principles enunciated. For example, a soil on which common red clover grows luxuriantly and has a prominent place in the farm scheme will require less nitrogen in commercial fertilizers in order to maintain the fertility than where legumes are raised with difficulty or do not form a part of the farm scheme.
One of the most important points to be emphasized is the fact that haphazard fertilization is not effective in maintaining soil fertility. If one starts out to establish a five-course rotation and build up his soil through a rational system of fertilization, he will obviously not obtain the full benefit of the rotation until he begins to get crops from the second round, which will be the sixth year from the beginning. It may happen, and unfortunately it has perhaps usually happened in the past, that during the first rotation the increase in crops has not paid for the cost of the fertilizers applied. In many instances a rational system of fertilization has not been introduced becausethe owner of the land could not afford to wait six years for his return. Profit in farming, therefore, does not consist in raising one big crop or even in obtaining a large balance on the right side of the ledger in a single year. It is both interesting and valuable to know that five tons of timothy hay, 45 bushels of wheat, 100 bushels of maize and 40 tons of cabbage may be raised on an acre, but the real profit in farming only comes through a lifetime of effort. To the man of capacity who prepares for his work the results will surely come, but they will not come all at once and, as in every other business, he must pay the price in hard work and close application to details.
In this connection it may be emphasized that one of the difficulties in successful farming is to find one man both interested and capable along the various lines essential to a successful farm enterprise. The danger is that a man will ride his hobby to the detriment of the other activities of the farm. A farmer friend of the writer, who keeps a horse andbuggy, cares so little for a horse that for several years he has walked two miles each morning and each evening rather than to take the trouble to hitch up his horse. If one visits a high-grade breeder of dairy cattle, he is very apt to find his pigs of ordinary character. On the other hand, a specialist in hogs is likely to keep scrub cows. A man may be an excellent wheat raiser and a poor potato grower, and the reverse. The breeder of live stock is likely to be lacking in his methods of producing farm crops, while the up-to-date, so-called general farmer is not likely to be a special lover of live stock. In like manner, the man may be a successful farmer, dairyman or horticulturist from the producing side, but be a poor salesman. In fact, those qualities of mind and heart which make for the best success from the standpoint of production, whether soil products or animal products, is not that which makes the best trader.
It is not expected that the young farmer will be materially different from his hundreds of thousands of predecessors, but thebetter a man is trained and the more fully he studies his own adaptabilities and deficiencies, the more likely he is to succeed in the open country. For this reason, the young man should be careful to get as broad a training as possible. It is, therefore, often more important for him to study those things which he dislikes than to study the things for which he has a natural taste.
There was a man in our town
And he was wondrous wise.
He knew that if he wanted crops
Hed have to fertilize.
Its nitrogen that makes things green,
Said this man of active brain;
And potash makes the good strong straw,
And phosphate plumps the grain.
But its clearly wrong to waste plant food
On a wet and soggy field;
Ill surely have to put in drains
If Id increase the yield.
And after I have drained the land
I must plow it deep all over;
And even then Ill not succeed
Unless it will grow clover.
Now, acid soils will not produce
A clover sod thats prime;
So if I have a sour soil,
Ill have to put on lime.
And after doing all these things,
To make success more sure,
Ill try my very best to keep
From wasting the manure.
So Ill drain, and lime, and cultivate,
With all that that implies;
And when Ive done that thoroughly
Ill manure and fertilize.

CHAPTER IXTHE ROTATION OF CROPS
The two essential reasons for a rotation of crops are: (1) The possibility of obtaining for the soil a supply of nitrogen from the air by introducing a legume at regular intervals, and (2) the prevention of injury to the crops from fungous diseases, insect enemies, weeds or other causes. Other reasons are often advanced, some of which are entirely erroneous, while others are of quite secondary importance.
The rotation should be carefully studied with reference to the farm scheme as previously outlined. Reasons for modifying the rotations are: (1) To change the kind or proportion of crops grown, (2) to change the amount of labor required, or (3) to increase the crop-producing power of the soil.
During 25 years the four crops of maize, oats, wheat, timothy and clover hay have been taken in rotation from the four tiers of plats at the Pennsylvania State College,so that the influence of the soil has been entirely eliminated. At the December farm prices for the decade ending December 1, 1906, the value of these four crops per acre have been: Maize, $29.67; oats, $14.49; wheat, $18.49; and hay, $18.05. It will be noted that during 25 years the average income from an acre of maize has been almost exactly twice that from an acre of oats. The region where these results were obtained is relatively unfavorable to a large yield of maize. It is obvious, therefore, that a modification in the rotation may modify the average income from the farm materially, provided such modification does not reduce the fertility of the soil. Thus, while the average income per acre during 25 years for the four-course rotation above mentioned was $20.17, if the rotation were increased to a five-course rotation by the addition of another year of maize, the average income would be $22.45 an acre.
It may be desirable to modify the rotation in order to increase or decrease a certain crop usually fed upon the farm. Thus,with a four-course rotation of maize, oats, wheat, clover and timothy, one-fourth the area would produce hay; while with a six-course rotation, composed of maize, oats, wheat, each one year, and hay three years, one-half the area would produce hay. If it is desired to still further reduce the area in oats and wheat, a seven-course rotation could be arranged with maize, two years in succession. This is the rotation that would be desirable for a dairy farm where it is planned to keep as many cows as practicable and to buy the concentrates largely. Either the wheat or the oats could be taken out of this rotation if either the one or the other were thought undesirable and a still greater amount of roughage desired.
On the other hand, there are places where the minimum amount of roughage is wanted. There are certain sections of the central West where it is possible to sow oats on corn stubble without plowing and where occasionally a rotation is practiced of maize, oats and mammoth clover. The clover is plowed for maize, the oats aredisked in upon the corn stubble and the next year the clover is pastured until about June 1, when it is allowed to go to seed. In this rotation the only roughage obtained is the corn stover and the oat straw.
Another result reached by this rotation is that only one-third the land is plowed annually. In the four-course rotation mentioned above three-fourths of the land must be plowed, while in the six-course rotation one-half is plowed each year. In other ways the character of the rotation modifies the labor. For example, the labor and cost of harvesting an acre of hay is much less than that of producing, harvesting and threshing an acre of wheat.
Rotations may often be planned with reference to the main or cash crop. Thus in the Aroostook (Maine) potato district the rotation is potatoes, oats and clover. The chief purpose of the oats and clover is to keep down the blight in potatoes and add through the clover nitrogen and organic matter to the soil.
A system of cropping that is bestwhen the owner operates the farm may not be desirable when the farmer is a tenant. When a farm is rented, the lease should provide that clover or other legumes occur with sufficient frequency to keep up the supply of nitrogen without the purchase of a considerable quantity in chemical fertilizers. The lease should be so drawn as to make it necessary for the tenant to keep live stock in order to realize the largest profit. The landlord should provide an equitable proportion of the mineral fertilizers when such are required.
The provisions of the lease and the character of the rotation will necessarily vary with circumstances, but the following system of tenant farming which has been employed for many years in Maryland will illustrate the principles just stated:
The lease provides for a five-course rotation consisting of maize, wheat, clover, wheat, clover. The landlord and the tenant share the maize and wheat equally, but the clover for hay or pasture goes entirely to the tenant, unless hay is sold, when it isdivided equally. They each provide one-half the commercial fertilizer and one-half the seed, except clover seed, which the tenant is required to furnish.
This lease provides for two clover crops out of every five crops raised, thus supplying nitrogen abundantly, and the terms of the lease are such that it is necessary for the tenant to keep live stock to consume these clover crops in order to secure the most profitable returns. The feeding of the clover makes it necessary to feed some or all the maize and may lead to buying additional concentrates.
Stable manure is thereby supplied for the field which is to raise maize, while mineral fertilizers may be applied to the fields sown to wheat. On the limestone soils of the eastern states 50 pounds each of phosphoric acid and potash per acre applied to the wheat, and 10 loads of stable manure per acre to the maize will probably be found sufficient to maintain the crop producing power of the soil.
In laying out a farm for a rotation it isdesirable to plan the number of fields or tracts that will go in a rotation and try to get these as nearly equal size as possible. Having decided upon the number of years the rotation is to run and having adjusted the fields or tracts accordingly, it is quite possible to modify the proportion of crops by adding one crop and dropping another at the same time. Thus, if there are six 20-acre fields, any one of the following rotations might be used and the change from one to another easily made:
During the first year the 20-acre field could be divided into four tracts of five acres each, containing potatoes, cabbage, tomatoes and sweet corn, and then followed for four or five years by any succession of crops above outlined. The point is that a definite adjustment of the farm to some generalmethod of rotation and a definite system of fertilization and soil renovation do not prevent a considerable latitude in the crops raised. It will be obvious that the longer the rotation the more flexible it becomes in this particular, which is a point to be considered in laying out the farm and in adjusting fields and fences.
In some cases it may be desirable on account of the arrangement of the farm or the character of the crops to be raised to have two distinct rotations of crops. For example, if the farm lends itself to be divided into eight tracts, a five-course rotation of maize, oats, wheat, each one year, and clover and timothy two years, and a three-course rotation of potatoes, oats or wheat and clover may be arranged.
CHAPTER XTHE EQUIPMENT
The workman is known by his tools. The problem of obtaining the most efficient machinery for the conduct of the farm without having an excessive amount is not easy of solution.
It is probable that the cost of maintaining machinery and tools is not less than 15%, 10% for upkeep and 5% for interest, even under the most careful management. Doubtless in practice it is as much as 25%. If this is conceded there must be a limit to the amount which may be economically invested in equipment. This is a place where the lead pencil may be used profitably. For example, if $125 is invested in a self-binder, the annual cost of the machine at 15% will be $18.75. If one has but 15 acres of grain to harvest, it may be better to hire a self-binder at $1 an acre. On the other hand, it may be necessary to own a self-binderin order to get the grain harvested at the proper time.
Among the machines requiring a considerable investment for the number of days used may be mentioned hay loaders, hay tedders, corn-binding harvesters and lime spreaders. There is a certain class of labor-saving devices, however, for which there is more or less constant need, as, for example, means of pumping water, methods of handling manure, both from the stable to the manure shed, and from the manure shed to the field. This leads to the remark that there is at present great need of modifying our traditional ideas concerning farm barns. Why do persons usually sleep on the second floor, while horses and cattle are placed in the basement? Three things have brought about the need of a radical revision of our practices concerning the planning of barns: (1) Our present knowledge of the difference in the function of food in keeping the animal warm, and that of producing work, flesh or milk; (2) the discovery of the bacillus of tuberculosis; and (3) the inventionof the hay carrier. It is not the purpose here to discuss barn buildings, but merely to call attention to the fact that the traditional barn has long since outlived its usefulness, and that the young farmer should plan his farm buildings to serve the purposes required in the light of modern knowledge.
Various attempts have been made to manufacture combined machines; that is, a machine which, by an interchange of parts or other modification, may be used for two or more purposes, as, for example, harvesting small grain and cutting grass. Such attempts have usually been unsuccessful. On the other hand, the young farmer should consider the range of usefulness of any given type of machine or tool; thus, a disk harrow is more efficient for some purposes than a spring-tooth harrow. For other purposes the spike-tooth harrow is better than the spring tooth. The spring-tooth harrow, however, will do fairly well wherever the disk harrow or the spike-tooth harrow is needed. When, therefore, only one of thesetools can be afforded, the spring tooth may be a better tool to buy than either the disk or the spike-tooth, although it is not for certain purposes as efficient as either of the others.
The kind of machine should obviously be adjusted to the conditions, as, for example, the size of the farm, and the character of the farming. Riding plows may be desirable on level land, but where it is necessary to plow up and down hill, walking plows should be used. The extra weight of the wheel plow is not a serious matter on level land, because the sliding friction has been transferred to rolling friction, but no mechanical device has been or can be invented which will decrease the power necessary to raise a given weight a given height. The various machines requiring horse power should be adjusted, as far as possible, to require the same number of horses. If the main unit is three horses, then, as far as possible, all machines should require three horses, such as plows, harrows, manure spreaders, harvesters, etc. If the activities of the farm are sufficient to requiresix horses then some of the tools may require three horses each, while others require a pair.
