This has been carried out and thepresent publication is offered as the result of a study of the plant lifehistory of the region with particular reference to the adaptations ofthe different crops. The information presented herewith has been drawn from manysources. Some field experiments have been carried out even in theshort time which has elapsed since the work was begun. The authors 142 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. have visited and sent letters to hundreds of ranchers in all parts ofthe valley in the work of collecting together the results of private ex-perimentation. This information has been sifted, analyzed and ar-ranged in order. Considerable data was obtained from the older irri-gated Coachella Valley and adapted to the conditions in ImperialValley. The findings of the branch station of the Arizona Experi-ment Station at Yuma in the Colorado River Valley have been given.

After exhausting all available sources of information,there of course still remained a number of crops concerning whichbut little definite data could be gained. This bulletin represents, therefore, to a certain extent, a digest ofindications as well as actual experimental results, and we hope thatin as much as it is intended primarily for newly arrived settlers whomay be largely ignorant of local conditions, that it will be receivedwith charity by those older residents of the valley who have gainedby costly experience much of the information we would disseminate.
