. Farm grasses of the United States; a practical treatise on the grass crop, seeding and management of meadows and pastures, descriptions of the best varieties, the seed and its impurities, grasses for special conditions, etc., etc. crop is 3, 884, 000 acres, and the average yield 1.3 tons. The grains are usedextensively for hay only on the Pacific Coast. Onnon-irrigated lands in Idaho, Washington, Oregon, and California, where the rainfall is sufficient to per-mit of farming, wheat is by far the most importantcrop. Over much of this area wild oats are verytroublesome, and the principal hay consists of patchesof wild oats cut in wheat-fields. Even where wild oatsare not troublesome, as where the rainfall is less thanabout eighteen inches annually, much wheat is cut forhay. If cut at the proper stage, wheat, and the othercereals as well, make excellent hay for all kinds ofstock. ^In California beardless barley is used exten-sively for hay; this crop is also coming into use inOregon and Washington for the same purpose. Al-falfa and brome-grass {Bromus inermis) are also rap-idly coming into favor on the wheat-lands east of theCascade Mountains in the two States last named. Throughout the Central and Southern States the. the; grass crop ii grain hay consists mostly of oats cut and fed in thesheaf, and of cow-peas. The thick patch of grain hayshown in southern Ivouisiana consists entirely of cow-peas grown on sugar plantations, both for hay and fortheir fertilizing efEedl on the soil. At the North, Cana-dian field peas are sometimes sown with oats for hay, but the area is quite limited. They hardly extend asfar south as central Pennsylvania and central Ohio. The hay crop next in importance is alfalfa, ofwhich 2, 094, 000 acres is reported in the Census of1900. This is confined almost entirely to the West, and largely to irrigated land in that section. Alfalfa, as an important crop, stops at the western limit ofother tame grasses, as shown in Fig. 17. It is nowrapidly gaining grou
