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. 44^ Yearbook of the Department of Agriculiure, Fig. 39.—Timothy is practically confined to the northeastern quarter of the UnitedStates, except for a scattered acreage in the moister districts of the Rocky MountainRegion. The western margin of the timothy acreage in the Dakotas, Nebraska, marks the beginning of the Black-isarth belt, where lime has accumlated inthe subsoil, of dense alfalfa acreage, and of dry-farming practices (see Figs. 6, 42,and 103,1. The southern boundary of timothy follows approximately the line of 200days in the frost-free season, or 77 mean summer temperature. The districts ofdensest production in northern Missouri, southern Illinois, eastern Ohio, and westernPennsylvania have, in general, rather heavy and slightly sour soils.
