34 REPORT OF OFFICE OF EXPERIMENT STATIONS. 



session of the California Legislature, whereby the commission has 

 agreed to set aside $17,500 to be expended under the supervision of 

 this office in preparing an irrigation map and ascertaining the folloAv- 

 ing facts : The water suppW, both surface and underground, available 

 for irrigation; the extent, character, and location of agi'icultural 

 lands susceptible of irrigation ; the present extent of irrigation ; and 

 the extent and location of unused waters. 



COLORADO. 



The Colorado Agricultural Experiment Station is now expending 

 $5,800 in cooperating with this office in conducting experiments per- 

 taining to the construction of weirs and concrete striicturas, irriga- 

 tion by pumping, coefficients of friction in ditches, and the iiTigation 

 and drainage requirements of different crops. V. M. Cone is in 



charge of this work. 



KANSAS. 



The legislature of this State in its 1911 session appropriated $2,000 

 per annum for two years to cooperate with this office in determining 

 the water requirements of the Kansas crops, the proper time to irri- 

 gate, the possibilities of using small water supplies in the short-grass 

 country, and the methods and cost of irrigating from wells. Experi- 

 ments along these lines are being carried on with water pumped from 

 a well on the farm of the Garden City substation of the Kansas State 

 Experiment Station. 



MONTANA. 



S. T. Harding was placed in charge of the work in this State at 

 the beginning of the irrigation season of 1911. The season just past 

 has been largely spent in collecting data for the preparation of a 

 bulletin on imgation in Montana. Henceforth he will spend the 

 greater part of his time in collecting data as to the methods and prac- 

 tices in use in the State and in advising and assisting settlei*s in 

 adopting better methods. 



NEBRASKA. 



F. W. Stanley was assigned to this State in June, 1911, and has 

 collected data and prepared a bulletin on irrigation in the State. 

 An agent will be maintained in the State during the coming year. 



NEVADA. 



Investigations to determine the seepage from and the waters rehirn- 

 ing to Humboldt River, the evaporation losses from iri'igated lands, 

 and the effect of different amounts of water on the quantity and 

 quality of the yields of crops are being carried on in this State in 

 cooperation with the Nevada Agi-icultural Experiment Station and 

 the State engineer. F. L. Peterson has charge of this work.
