40 EEPORT OF OFFICE OF EXPERIMENT STATIONS. 



UTAH. 



Prof..W.W. McLaughlin has charge of the work in this State, with 

 headquarters at Logan. The State cooperates with this office through 

 the experiment station, one-half of the expenses of the work being 

 paid from State funds. This being the oldest irrigated section of 

 the country, the work is naturally of a more technical and scientific 

 nature than in the newer sections. A study has been made of the 

 lateral and downward movement of the water in soil with different 

 amounts of water ai^plied at different times and with different 

 methods of cultivation. In this connection studies have been made 

 to determine the proper length, dej^th, and distance apart of furrows 

 in order to produce maximum yields with minimum quantities of 

 water. The investigations have shown that light early irrigation 

 and heavy late irrigation tend to a light production of fodder or 

 straw and a heavy production of seed, while heavy early irrigation 

 and light late irrigation cause the reverse. The number of irriga- 

 tions during a season have been found to have a very important 

 bearing on the yield. In the iiTigation of sugar beets it was found 

 that merely by a better handling of the same quantity of water the 

 sugar content was increased 2.1 per cent. Considerable work has 

 also been done in peach and apple orchards to determine the effect 

 of different quantities of water and different times of application on 

 the growth of the trees and the growth of the fruit. In peach 

 orchards it was found that the most rapid gi'owth of the tree and the 

 stone is made in the fore part of the season, while that of the peach 

 is made in the last part of the season and liberal applications of 

 water in late summer resulted in large yields. Prof. McLaughlin 

 has recently prepared a Farmers' Bulletin on the Irrigation of Grain. ^ 



ARIZONA. 



P. E. Fuller, located at Phoenix, has charge of the work in this 

 State and also has general charge of investigations of power for 

 irrigation throughout the West. His work in Arizona has consisted 

 chiefly of giving personal advice to irrigators, especially in the instal- 

 lation of pumping plants. Mr. Fuller has prepared a Farmers' Bul- 

 letin on the Use of AYindmills in Irrigation in the Semiarid West.^ 



NEW MEXICO. 



F. L. Bixby has charge of this field in connection with work in the 

 agricultural college. A careful study is being made of irrigation 

 conditions throughout the Territory, and it has been found that the 

 methods in practice for the most part are very crude. The chief work
