Farmers' bulletin (United States. Dept. of Agriculture) ; no. 864

"The first few pages of this bulletin contain some suggestions to those who are confronted with the task of selecting a farm under an irrigation system. Arid soils and water supplies are considered in a general way from the standpoint of the irrigator. The greater part of the paper is taken up with a somewhat fuller description of how to locate and build farm ditches, how to prepare land to receive water, how to irrigate a few of the staple crops, and how much water to apply." -- p.
