IRRiaATION INVESTIGATIONS. 4Yl 



huiklino- of largo contral power phint.s for the o-eneration of electrical 

 eiieroy by the conaumption of crude oil. This energy can be distrib- 

 uted to motors on the respective farms of the shareholders and enable 

 water to be lifted from wells 25 feet deep at a cost of $1 per acre-foot. 

 It seems reasonable to conclude that cheap fuel, together with the 

 utilization of the fall c)f the mountain streams, will produce cheap 

 power, and that cheap power will tend to increase at a rapid rate the 

 nunil)er of pumping plants. This branch of the investigation in 

 California is being carried on as follows: 



(1) Collecting descriptions of all existing plants and tabulating the 

 results. 



(2) Making field tests of plants in operation. 



(3) Measuring the amount of water discharged by different plants 

 and ascertaining the average duty of water under pumping plants. 



(4) Making laboratory tests to determine the efficiency of various 

 makes of pumps and engines. 



NEVADA. 



Gordon II. True, Professor of Animal Husbandry, Nevada State University, in 



charge. 



The legislature of Nevada appropriated $2,000 to aid in cooperative 

 investigations between this Office and the State agricultural experi- 

 ment station. A plan for cooperative studies of the duty of water 

 and the best means of preventing or removing the evils caused by 

 seepage water by drainage was prepared by this Office and submitted 

 to the governor. Consideration of this was dela^'ed until after the 

 time for beginning such studies, and the only investigations carried 

 on this season in Nevada have been made at the State experiment 

 station. 



These have embraced measurements of the duty of water and deter- 

 minations of the los.ses from seepage and evaporation in ditches, which 

 are carried on under the direction of Professor True. In addition to 

 these Professor True has made two reports, one on the methods of 

 preparing land for irrigation, and one on certain types of current 

 wh(>cls in use in Nevada. These reports are a part of a general coop- 

 erative investigation carried on under the direction of this Office, to 

 be referred to hereafter. 



OREGON. 



James Withycombe, Director Oregon Experiment Station, in charge. 



The irrigation problems of Oregon are of an exceptional character. 

 The western and most ])opulous part of the State is humid. To more 

 than three-fourths of (he people irrigation is a mattei- having no direct 

 interest, and its development in the arid sections has been neglected. 

 In the eastern and central portions of the State are large areas, esti-
