Excerpt from The Principles of Irrigation Practice
Irrigation and dry-farming are rapidly conquering drought. By these twin arts, bountiful and regular harvests may be gathered in the humid regions during the periodic dry seasons; and in the arid regions, the great "deserts" may be converted into most fruitful fields. Irrigation has a splendid record of success from the beginning of history; dry-farming has only in recent days extended its conquests into the more arid regions; both have become more powerful in conquering drought as modern science has been applied to them.
Successful irrigation-farming is the joint product of the engineer and the farmer. To the engineer is given the heavy and responsible task of constructing properly a permanent system of dams and canals from which water may be drawn; to the farmer belongs the apparently humble but unending and difficult task of using the water in the best manner for crop-production. Both workers are essential for success; but, the work of the farmer determines the permanence and extent of agriculture under irrigation.
Much has been written about irrigation for the engineer, but little for the farmer. The few who have written about farming under irrigation have, most frequently, prepared crop or soil manuals, in which the use of water has formed a minor part.
