PERMANENT PASTURES. 379 



under such conditions to sow large quantities of seed, 

 as the moisture is not enough to sustain a dense sward. 

 In the irrigated districts toward the mountains, Rus- 

 sian brome grass, alone or with alsike and white clover, 

 would make excellent permanent pasture. 



For the Upper Mississippi Basin. For the states in 

 this group, see p. 347. In eastern Minnesota, all of 

 Wisconsin, much of Illinois, Missouri, and Iowa, the 

 best permanent pasture grass is Kentucky blue ; in east- 

 ern North and South Dakota and in a part of Nebraska, 

 Russian brome, and in Kansas and part of Missouri, 

 orchard grass and in some localities Russian brome. 

 In northeastern Minnesota ancT also in northern Wiscon- 

 sin, Kentucky blue grass and white clover make excel- 

 lent permanent pasture and in the same medium red 

 clover will endure for a term of years. 



In the blue grass region of the area named north of 

 parallel 40 degrees, the following combination of grasses 

 may be expected to give good results: 



Lbs. per Acre. 

 Timothy ................................. 4

South of parallel 40 and also in the blue grass re- 

 gion, the above formula should be changed to that given 



below
