OFFICE OF EXPERIMENT STATIONS. 841 



A cooperative agreement has been entered into with the Arizona 

 Experiment Station providing for an investigation of the irrigation 

 possibilities of that State and the work during 1913 will consist of 

 duty of water investigations in the Salt River Valley and other 

 localities in Arizona. Under the cooperative agreement with the 

 Colorado Experiment Station, a duty of water investigation will be 

 begun in San Luis Valley. 



It is planned to publish one or more bulletins during the year upon 

 pumping and upon irrigation in the humid sections. An attempt 

 will be made to complete the series of bulletins upon irrigation in 

 the several States and the practical series upon irrigation of different 

 standard crops. A series of publications will be begun upon irri- 

 gation structures of different kinds and another upon the organiza- 

 tion, operation, and management of canals and irrigation enterprises. 

 Revisions will be made as rapidly as possible of the bulletins already 

 issued upon irrigation in several States. 



WORK FOR THE FISCAL YEAR 1914. 



All the lines of work that have been begun, or which will be started 

 during 1913 and have not been finished by 1914, will be continued 

 chiring that year. So far as possible, one or more agents will be 

 assigned permanently to each of the arid and semiarid States and the 

 field force in the humid and rice growing regions and also that work- 

 ing on pumping and power will be increased. The plan of supplying 

 practical information to settlers by means of bulletins, lectures, 

 demonstrations, and the personal advice of agents will be continued. 

 The chief aims of the work will be to bring about a reduction in the 

 cost of obtaining water by pumping and storage; to encourage a more 

 economical use of water, by demonstrating better methods of dis- 

 tributing and applying water and conserving it in the soil; to reduce 

 the losses of water due to seepage, evaporation, and irrigation at times 

 when the application of water does little or no good to crops; to 

 bring about a better understanding of the conditions in and the possi- 

 bilities of different irrigated sections; and to encourage a better 

 organization of irrigation enterprises, better methods of managing 

 and operating canals, and a better enforcement of the existing irriga- 

 tion codes of the several States. 



DRAINAGE INVESTIGATIONS. 



Mr. C. G. Elliott continued in charge of drainage investigations 

 until February 3; at the close of the fiscal year his successor had not 

 been appointed, Dr. E. W. Allen, assistant director, being temporarily 

 in charge. 



During the past year the unfinished projects of the year previous 

 have been completed and many new projects and investigations taken 

 up. A summary of the work done eml)races surveys, working plans 

 and profiles, and reports made for various drainage districts, which 

 may be classed as follows :
