It is through the efforts of the experiment stations that the knowledge of the day has been reduced to a science of dry-farming. Every student of the subject admits that much is yet to be learned before the last word has been said concerning the methods of dry-farming in reclaiming the waste places of the earth. The future of dry-farming rests almost wholly upon the energy and intelligence with which the experiment stations in this and other countries of the world shall attack the special problems connected with this branch of agriculture. The United States Department of Agriculture The Commissioner of Agriculture of the United States was given a secretaryship in the President's Cabinet in 1889. With this added dignity, new life was given to the department. Under the direction of J. Sterling Morton preliminary work of great importance was done. Upon the appointment of James Wilson as Secretary of Agriculture, the department fairly leaped into a fullness of organization for the investigation of the agricultural problems of the country. From the beginning of its new growth the United States Department of Agriculture has given some thought to the special problems of the semiarid region, especially that part within the Great Plains. Little consideration was at first given to the far West. The first method adopted to assist the farmers of the plains was to find plants with drouth resistant properties. For that purpose explorers were sent over the earth, who returned with great numbers of new plants or varieties of old plants, some of which, such as the durum wheats, have shown themselves of great value in American agriculture. The Bureaus of Plant Industry, Soils, Weather, and Chemistry have all from the first given considerable attention to the problems of the arid region. The Weather Bureau, long established and with perfected methods, has been invaluable in guiding investigators into regions where experiments could be undertaken with some hope of success. The Department of Agriculture was somewhat slow, however, in recognizing dry-farming as a system of agriculture requiring special investigation. The final recognition of the subject came with the appointment, in 1905, of Chilcott as expert in charge of dry-land investigations. At the present time an office of dry-land investigations has been established under the Bureau of Plant Industry, which cooperates with a number of other divisions of the Bureau in the investigation of the conditions and methods of dry-farming. A large number of stations are maintained by the Department over the arid and semiarid area for the purpose of studying special problems, many of which are maintained in connection with the state experiment stations. Nearly all the departmental experts engaged in dry-farm investigation have been drawn from the service of the state stations and in these stations had received their special training for their work.
