This bulletin discusses the effect of crop rotation practices on soil productivity, and also describes the possible effects of fertilizers and other forms of soil improvement. "The purposes of the discussion which follows are to emphasize the value of crop rotation in farming economy and to stress the principles of rotation in their relation to the maintenance of soil productivity and to soil improvement." -- p. 5

"This bulletin deals with those cultivated forage crops that seem of greatest promise for the dry-farming districts of northern Nebraska and the Dakotas west of the ninety-eighth meridian. Frequent crop failures in the more arid portions of these States result from a low annual precipitation, the irregularity of its amount and distribution during the growing season, and high evaporation. Under conditions of extreme drought, cultivated crops can seldom be economically substituted for native vegetation, and the utilization of such lands for grazing and the cutting of wild hay is most generally advisable. Greater forage production on the better lands may be effected by growing certain cultivated legumes, grasses, and roots." -- p. ii.

"With the disappearance of many of the fine-pelted wild fur bearers from certain parts of the United States, the use of rabbit skins is steadily increasing. Aided by modern processes, American fur dressers and dyers have become so expert in changing the colors and appearances of furs that in many instances the pelt of the rabbit, under a variety of trade names, is replacing many that are more attractive and costly.... Methods of handling rabbit skins, from the time the pelt is removed until it reaches the raw-fur market or is tanned for home use, are described in this bulletin." -- p. ii

"Success in the propagation of game birds has been enjoyed in the United States by individuals, by sportsmen's organizations, and by State game departments. There have been failures, of course, but methods that assure success are known. These are treated concisely in this bulletin.... Developed methods need only be carried out with energy and intelligence to produce satisfactory results. Raising game birds may be made profitable, since the demand exceeds the supply of adult birds for breeding, of both young and and adults for restocking, and of eggs for distribution to farmers and shooting clubs." -- p. ii. Among the birds discussed are pheasants, quail, partridges, grouse, turkeys, ducks, geese, and swans.

"The purpose of this bulletin is to acquaint farmers with the possibilities of developing the power of small streams by converting it into electrical energy and the uses to which such power can be put; to give information which will enable them to avoid unnecessary expenditures; to explain how to determine the power a stream will supply; and to indicate the sources from which to secure additional information in regard to the approximate cost of installing a plant suited to the power available. The details of design, installation, and operation of electrical equipment are not within the scope of this bulletin." -- p. ii

Revised edition. "The breeds of chickens included in the Asiatic, English, and French classes are in the main of a relatively large size, and have been developed primarily as meat breeds. They are not so commonly kept in this country [the United States] as either the general-purpose or the egg breeds. The best-known meat breeds in the United States are those of the Asiatic class. However, the breeds of the English and French classes, while averaging somewhat smaller in size than those of the Asiatic class, were developed for their table qualities and therefore are popularly grouped among the meat breeds. In the opinion of many persons the Sussex and Orpington breeds, both English, are general-purpose breeds. The Orpington, in particular, is a fairly common and popular farm fowl in the United States. The best-known section of the United States in which large table fowls of superior quality are produced in considerable quantities is the South Shore distrct of Massachusetts, near Boston. The chicks are hatched in the fall or early winter, and both males and females are grown to a good size and marketed as South Shore roasters. The males usually are caponized, but are marketed as roasters rather …

This bulletin discusses the cattle-fever tick and methods for controlling it. Possible methods include dipping, pasture rotation, and arsenical dips. The life history of the tick is also discussed.

"The Hessian fly undoubtedly is the most injurious insect enemy of wheat in the United States. During the last 37 years at least seven general outbreaks of this pest have occurred in the States east of the Mississippi River. These invasions have averaged about one every five years, although they have occurred at rather irregular intervals. The last one was very destructive and was at its height during the period from 1914 to 1916.... A large proportion of such losses is preventable, although no remedy is known which will destroy the pest or save the crop once it has become thoroughly infested. Control and preventive measures are described on page 13 and summarized on page 16." -- p. 2

This pamphlet discusses insects that damage rice crops: "The slender, milk-white grub or 'maggot' of the rice water-weevil lives on the roots of rice, and whether it feeds little or much upon them, kills practically all the roots that it attacks. This pruning of the roots weakens the rice plant and often kills it. Another enemy of this staple crop of the South is the stink bug, which sucks the juices from the soft grains of rice. The fall army worm, when it becomes abundant, works great havoc in its attack upon young rice. Other insects also, such as the rice stalk-borer, infest the rice field, and the rice planter must constantly guard his crop against them. This bulletin tells when to plant, and when to flood and drain the fields in order to reduce the numbers of these pests, and recommends other measures that will prevent attack by the many minor species of insects which normally breed in and near rice fields." -- p. 2

"The cost of clothing has been rising rapidly; therefore more than ever we need to know how to choose and use our garments wisely. This bulletin gives practical suggestions as to how to select clothing that will be both attractive and durable and how to care for it so that it will render full service." -- p. 2

This bulletin promotes the use of tractors on farms in the Corn Belt of the United States in order to increase agricultural productivity. It discusses the possible uses of tractors and the displacement of horses on farms.

"All frost protection methods, from the simplest to the most complicated, can be carried on more successfully if the processes by which the earth's surface cools at night and the factors which influence the rate of cooling are well understood. In the first part of this bulletin an attempt has been made to describe in a simple, elementary manner the changes that take place at and near the earth's surface on a frosty night, so that persons protecting plants or trees may be able to understand how their protective devices operate to prevent damage and in what manner they are most efficient. In treating a matter of this kind it is practically impossible to eliminate all technical terms, but so far as possible these have been carefully explained in simple language. The larger portion is given over to a discussion of the various methods and devices now being used for protection against frost, together with a chapter on temperatures injurious to plants, blossoms, and fruit." -- p. 2

"This bulletin is intended to aid the prospective purchaser of dusting machinery for cotton boll weevil control in selecting a satisfactory model and one adapted to the needs of his particular farming conditions. Different localities frequently require different types of machinery, and the farmer should make sure he is securing one suitable for his needs." -- p. 2

"Vetch, which has become an important forage crop throughout the Southeastern States, needs protection from the same insect that works such havoc on corn and cotton. This corn earworm, or cotton bollworm, is the most serious pest that growers of vetch have to combat. The caterpillars eat both the foliage and the seed pods, and, if the infestation is heavy, make the crop practically worthless. Vetch intended for a hay crop generally escapes serious injury, as it is cut before the caterpillars are large enough to do much damage. It is recommended that a crop intended for seed be carefully watched and if the insects become numerous an insecticide be applied at once or the vetch cut for hay. Spraying, dusting, the use of poisoned-bran bait, and other control measures are discussed and summarized in this bulletin." -- p. 2

"Beekeeping methods suitable for the clover region are well developed but many beekeepers of this region are failing to obtain the full available honey crop because of deficiencies in their practice. A system of management is here given which will result in a full crop from these sources. The variation in the value of the clovers to the beekeeper is also discussed and the methods to be followed in bringing the clover region back to its former prominence in honey production are outlined." -- p. 2

"The production of the full honey crop from buckwheat requires a plan of apiary management quite different from that of most other beekeeping regions. A system of management is here given which will result in a full honey crop and at the same time control European foulbrood, which is so prevalent in the buckwheat region. Methods are also given which may be used in case the clovers are valuable as sources of nectar." -- p. 2

This bulletin discusses beef production in the Corn Belt of the United States with special regard to feed preparation, cattle selection, and methods for fattening cattle.

"Many thousand colonies of bees occur in the region where the tulip-tree is abundant but the honey crop from tulip-tree flowers inconsiderable. Too few beekeepers in this region have modern equipment, it is true, but the greatest loss comes from the fact that they do not care for their bees so as to have them ready to gather the abundant nectar from this early-blooming tree. In this bulletin a methods is given for the management of the apiary so that the full honey crop from this source may be obtained." -- p. 2

This bulletin discusses the chinch bug, an insect which destroys corn, wheat, oats, and forage sorghums in the United States. The chinch bug's life cycle and habits are discussed as well as conditions favorable to chinch bug outbreads and control measures.

This bulletin discusses wheat scab, a fungal disease of wheat, rye, barley, and oats that is caused by a parasite. It describes the appearance of afflicted crops as well as the parasite's life cycle and proposes a variety of control measures.
