The jiutbors divide the State into 5 regious: (1) Tlie Sioux Valley 

 region, (2) the James River Valley region, (3) the Missouri River Valley 

 region, (4) the Great Range region, and (5) the Black Hills region. The 

 characteristic grasses of the Sioux Valley region are the blue stems, 

 especially the big blu'e stem aud the bushy blue stem. About 90 per 

 cent of the native hay and 80 per cent of the i)asturage is obtained 

 from the 2 grasses just named, together with switch grass. Western 

 wheat grass furnishes about J>0 jier cent of the native hay and most of 

 the pasturage of the James River Valley region. Blue joint and the 

 sand grasses are also very common here. The flora of the Missouri 

 Valley region is varied. Western wheat grass furnishes the greater 

 I)art of the hay in the Range region. Other specially imi)ortant grasses 

 in this region are blue grama and buftalo grass. The Black Hills 

 region has a number of native species. Of the introduced or culti- 

 vated grasses Hungarian brome grass {Bromus inermis) has thus far 

 been more satisfactory in the State than any other grass tested, having 

 endured both the drought of summer and tlie severe weather of winter. 



Timothy succeeded on rich and moist soil, but is not regarded as 

 suitable for the drier parts of the State. Red fescue, sheep fescue, and 

 hard fescue "are all hardy enough to stand the climate in the eastern 

 part of the State, and probably also that of most localities east of the 

 MissouriRiver or in the Black Hills. Tall fescue aud meadow fescue give 

 paying crops of hay on moist meadows. Kentucky blue grass, or June 

 grass, as it is often called, is hardy in the Sioux Valley, and will probably 

 do well 111 many other parts of the State. The native grasses which have 

 shown themselves worthy of cultivation are western wheat grass, slender
