The Irrigation Investigations of the Office of Experiment Stations are governed by the following clause of the act making appropriation for the U. S. Department of Agriculture for the year ending June 30, 1910. Irrigation Investigations.— To enable the Secretary of Agriculture to inves- tigate and report upon the laws of the States and Territories as affecting irriga- tion and the rights of appropriators and of riparian proprietors and institutions relating to irrigation and upon the use of irrigation waters, at home and abroad, with especial suggestions of the best methods for the utilization of irrigation waters in agriculture, and upon the use of different kinds of power and appli- ances for irrigation, and for the preparation and illustration of reports and bul- letins on irrigation, including rent and the employment of labor in the city of Washington or elsewhere, and all necessary expenses, seventy-five thousand dollars. The purpose of the Irrigation Investigations is a better use of the water supply in those sections of the country where irrigation is prac- ticed. The work is divided into three general classes : (1) The study of the adaptation of the laws and other institutions governing the use of water to the needs of the agricultural industry. (2) Scientific and technical investigations of losses of irrigation water by evaporation, seepage, and in distribution ; of the relation of irrigation to the quantity and quality of crops ; of the adaptation of methods of applying water to soils and crops ; and of the measurement, distribution, storage, and pumping of w r ater for irrigation. (3) The collecting and publishing of practical information regarding irrigation practice. PUBLICATIONS OF THE OFFICE OF EXPERIMENT STATIONS RELATING TO IRRIGATION.
