agencies which can be employed to conserve the present water sup- 

 ply. During the coming season the investigation will be directed 

 toward collecting facts which will show the sort of legislation needed. 

 They will include collection of data showing how far development can 

 continue without affecting the water suppl}^ of j)resent irrigators, the 

 best methods of increasing or reinforcing this supply, the best means 

 of economizing in the use of water, and the methods, if any, by which 

 the ingress of salt water may be prevented. 



The report on rice irrigation along the Atlantic coast, which forms 

 a part of Bulletin No. 113 of this Office, will be supplemented by fur- 

 ther studies of the economic questions which confront the irrigators 

 of this section. It is believed that pumps can be profitably used for 

 the irrigation of the higher land, and that many of the methods 

 which are now being employed to advantage in Louisiana and Texas 

 can be used here. 



COOPERATION WITH STATE AGENCIES. 



The efforts of this Office to promote cooperative arrangements with 

 the agricultural colleges and experiment stations and the State engi- 

 neers' offices will be continued. In this way the results of widely sep- 

 arated investigations can be brought together and order and system 

 in the cooperative work of State agencies promoted. It also enables 

 this Office to avail itself of the services of highly trained scientists at 

 far less cost than would be required to secure their continuous employ- 

 ment. The work of the Office has also been greatly aided by appro- 

 priations for irrigation made by the State legislatures of Nevada, Idaho, 

 and Montana, by the cooperation and assistance of different railway 

 lines in the West, and by associations for the reform of irrigation laws.
