agriculture of the reclamation projects. It has been necessary to 

 make various minor modifications in the plans of work. In spite 

 of the instability of agricultural conditions on the reclamation proj- 

 ects and in the country generally, substantial progress was made 

 during the year in the work in promoting agricultural industries. 



DAIRYING. 



During the year demonstration work in dairying has been con- 

 ducted on the Truckee-Carson, Huntley, Minidoka, Tieton, Shoshone, 

 Boise, North Platte, and Uncompahgre projects. In this work the 

 settlers have been assisted in securing stock, improving local dairy 

 herds through breeding and cow testing, controlling diseases, plan- 

 ning and constructing barns and silos, and in improving their 

 methods of feeding and marketing. During the year improved 

 methods of financing the purchase of breeding stock were inaugu- 

 rated on. several of the projects. One cow-testing association was 

 established on the Truckee-Carson project and another on the Tieton 

 project. In addition to this association testing work, systematic 

 cow-testing work in 71 individual herds was carried on. A bull 

 association was organized on the Tieton project. Three bull clubs 

 were organized. New cheese factories were placed in operation on 

 the Boise, Uncompahgre, Minidoka, and Tieton projects. The 

 operation of these cheese factories has done much to improve the 

 marketing conditions affecting dairy projects. As a means of secur- 

 ing a better utilization of the locality-grown feeds, much attention 

 has been paid to the building of silos by dairy farmers. During 

 the year assistance was given in the construction of 42 silos, and the 

 educational work done in this connection has resulted in greatly in- 

 creased interest in the subject. Speaking generally, the dairy in- 

 dustry on the reclamation projects has experienced marked improve- 

 ment during the year, particularly with reference to increased com- 

 munity interest and cooperation. 



THE SWINE INDUSTRY. 



Work in connection with the establishment of the swine industry 

 is in progress on the North Platte, Truckee-Carson, Huntley, Mini- 

 doka, Tieton, Shoshone, Boise, and Uncompahgre projects. The 

 settlers on these projects have been aided in solving the problems 

 of breeding, feeding, housing, and marketing their hogs, and in the 

 control of diseases, particularly hog cholera. The unusually high 

 prices for feed and for pork resulted in a marked reduction in the 

 swine population on most of the projects where we are operating, 

 but the decline in the swine population resulted chiefly from reduc- 

 tions in the sizes of individual herds. There is a marked tendency to 

 grow swine in smaller herds than was formerly the case, and this 

 tendency is being encouraged, as it makes for' a better utilization 

 of waste materials and hence a lower cost of production. Special 

 attention was paid during the year to better feeding, with particular 

 reference to better methods of utilizing locally grown feeds. As a 

 part of this work 53 practical farm feeding tests were conducted on 

 the North Platte, Boise, Uncompahgre, Tieton, Shoshone, Huntley,
