Arizona Agricultural Experiment Station 241 



the neighboring- State of CaHfornia or as may be found between the 

 Gulf of Mexico and the Canadian hne, demands made upon the Agri- 

 cuUural Staff are very diverse in character. While, however, the State 

 of California has an Agricultural Staff of 130 men to handle their 

 situation, and while the agricultural zone between Canada and the Gulf 

 i? served by a whole group of agricultural colleges and experiment sta- 

 tions, Arizona, which, on account of its unique agricultural conditions 

 receives less than the usual amount of help from outside organizations, 

 must handle its problems with a staff at present numbering 21 people. 

 Inevitably, in order to work effectively, this Staff has concentrated its 

 efforts from year to year upon a comparatively small number of prob- 

 lems, laying aside completed work from time to time and taking up new 

 projects as time and funds have allowed. 



In this way, the efforts of the Staff" having been shaped largely by 

 demands made upon it by the agricultural public, the research work of 

 the Station has for the most part fallen under three general heads re- 

 lating to (1) the development and eff'ective utilization of agricultural 

 water; (2) intensive cultivation of irrigated lands; and (3) the utiliza- 

 tion, by dry-farming methods and by grazing, of lands for which there 

 is but limited water supply. With reference to internal organization 

 this work has been carried on by departments of research classified 

 according to technique as follows : agronomy, animal husbandry, botany, 

 chemistry, entomology, horticulture, plant breeding, and irrigation. 

 Following is a classified list of subjects, exclusive of the 27 Annual 

 Reports, thus far published upon by these departments, comprising 77 

 Bulletins and 123 Timely Hints for Farmers, besides a considerable list 

 of papers published in scientific journals and a constant output of news- 

 paper articles, addresses and other instruments of information : 



Soils, water, alkali and farm management 35 



Climate 6 



Crops 90 



Weeds, insect pests, and plant diseases 23 



Irrigation 17 



Animal industry and the range 29 



This fund of agricultural information constitutes a body of knowl- 

 edge indispensable at a time when increasing immigration and a quick- 

 ening in agricultural development has made more urgent the public 

 demand for such information. 



This body of agricultural knowledge also serves as a basis for 

 teaching, more particularly in the sub-tropical and semi-arid region 

 which constitutes the field of work. Indeed, until such knowledge had 

 been achieved it would hardly have been possible to establish a satisfac-
