Revised edition. "This bulletin applies to that part of the United States in which ordinary farm crops are grown largely under irrigation. It describes methods practiced in the more important commercial strawberry-growing districts in the irrigated regions of the West; it aims to aid those familiar only with local and perhaps unsatisfactory methods, as well as inexperienced prospective growers. The fundamental principles of the irrigation of strawberries are substantially the same as those which apply in the growing of other crops. Details of operation must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid regions frequently suffer from drought, which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those localities who could install an irrigation system at small expense. Detailed information is also given as to soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, and shipping. Methods of using surplus strawberries for preserves and jams, for canning, and for flavoring for various purposes are given." -- p. 3

"At least 66 distinct varieties of soft red winter wheat, known by nearly 400 different names, are grown commercially in the United States, and additional varieties are grown experimentally. These varieties differ widely in yield, adaptation, milling and baking value, and other characteristics. The most widely grown varieties in the United States in order of importance are Fultz, Fulcaster, Mediterranean, Poole, Red May, Red Wave, and Harvest Queen. The area of each of these varieties in 1919 varied from about 4,800,000 acres to about 1,000,000 acres." -- p. 2
