The Colorado Station was the first to declare its good intentions in the matter of dry-farming, by inaugurating definite experiments. By the action of the State Legislature of 1893, during the time of the great drouth, a substation was established at Cheyenne Wells, near the west border of the state and within the foothills of the Great Plains area. From the summer of 1894 until 1900 experiments were conducted on this farm. The experiments were not based upon any definite theory of reclamation, and consequently the work consisted largely of the comparison of varieties, when soil treatment was the all-important problem to be investigated. True in 1898, a trial of the "Campbell method" was undertaken. By the time this Station had passed its pioneer period and was ready to enter upon more systematic investigation, it was closed. Bulletin 59 of the Colorado Station, published in 1900 by J. E. Payne, gives a summary of observations made on the Cheyenne Wells substation during seven years. This bulletin is the first to deal primarily with the experimental work relating to dry-farming in the Great Plains area. It does not propose or outline any system of reclamation. Several later publications of the Colorado Station deal with the problems peculiar to the Great Plains. At the Utah Station the possible conquest of the sagebrush deserts of the Great Basin without irrigation was a topic of common conversation during the years 1894 and 1895. In 1896 plans were presented for experiments on the principles of dry-farming. Four years later these plans were carried into effect. In the summer of 1901, the author and L. A. Merrill investigated carefully the practices of the dry-farms of the state. On the basis of these observations and by the use of the established principles of the relation of water to soils and plants, a theory of dry-farming was worked out which was published in Bulletin 75 of the Utah Station in January, 1902. This is probably the first systematic presentation of the principles of dry-farming. A year later the Legislature of the state of Utah made provision for the establishment and maintenance of six experimental dry-farms to investigate in different parts of the state the possibility of dry-farming and the principles underlying the art. These stations, which are still maintained, have done much to stimulate the growth of dry-farming in Utah. The credit of first undertaking and maintaining systematic experimental work in behalf of dry-farming should be assigned to the state of Utah. Since dry-farm experiments began in Utah in 1901, the subject has been a leading one in the Station and the College. A large number of men trained at the Utah Station and College have gone out as investigators of dry-farming under state and Federal direction.
