The hay and forage acreage, it will be noted,is largely concentrated in the Hay and Pasture Kegion and around the margin of theCorn Belt, the greatest State acreage being found In New York and the greatest ton-nage production in Wisconsin. • Relative to the acreage In crops, however hay andforage is most important in the Rocky Mountain Region, where it occupies 55 per centof the crop land. 448 Yearbook of the Department of Agriculture, Fig. 39.—Timothy is practically confined to the northeastern quarter of the UnitedStates, except for a scattered acreage in the moister districts of the Rodtv MountainRegion. The western margin of the timothy acreage In the Dakotas, Nebraska, andKansas marks the beginning of the Black-earth belt, where lime has accumlated inthe suhsoU, of dense alfalfa acreage, and of dry-farming practices (see Figs. 6, 42,and 103). The southern boundary of timothy follows approximately the line of 200days m the frost-free season, or 77° mean summer temperature. The districts ofdensest production in northern Missouri, southern Illinois, eastern Ohio, and westernrennsylTania have, In general, rather heavy and slightly sour soils.
