348 GRASSES AND HOW TO GROW THEM. 



areaSj but Russian brome lias boon snfficioiitly tested 

 to demonstrate that it stands high in adaptation both 

 for hay and pasture. What has been said of those 

 portions of Minnesota and Wisconsin, will also apply, 

 in the main, to Iowa and Illinois except that adapta- 

 tion for growing clover in these, though high, is not 

 so high as the portions of Minnesota and Wisconsin 

 that were specified. Orchard grass and tall oat grass 

 have but medium adaptation. In southwestern and 

 western Minnesota and in the Dakotas, timothy and 

 clover pastures are of short duration, although the 

 production of both are improving and Russian brome 

 is growing in favor. In Missouri, timothy and clover 

 do well in providing hay and grazing, but in the parts 

 of Kansas and ISTebraska included, while clovers flour- 

 ish, timothy does not quite eqlial orchard grass in fur- 

 nishing pasture; the same is true of Russian brome. 

 Alfalfa is coming to be the leading plant in providing 

 hay and swine pasture in eastern Kansas and I^e- 

 braska; its cultivation for these is rapidly extending 

 in the other portions of the area now being considered. 



For the Semi-Arid Belt. — In this group of states 

 are included all those that lie east of the Cascade and 

 Coast mountains, exclusive of the irrigated valleys 

 and west of the states included in the upper Missis- 

 sippi and southeastern groups. 



In the greater portion of this area, the pasture and 

 hay grasses are such as nature provides; the former 

 on the uplands and the latter in the depressions. These 

 vary with the locality and the degree of the humidity. 

 They include a great variety of grasses, nearly all of
