is primarily adapted to a region where the air is dry, 

 and under such conditions, as in our West, thrives like 

 a weed. In the more humid sections of the East and 

 South, however, alfalfa thrives well only when the soil 



is deep, well drained and 

 contains a sufficient quan- 

 tity of lime. On this ac- 

 count it has become im- 

 portant mainly on soils 

 of limestone origin. On 

 such soils it will far out- 

 yield any other perennial 

 forage crop.

 its commonly cultivated 

 form is a native of Eu- 

 rope; various forms of it 

 are native in America, but 

 these did not occur origi- 

 nally in the region where 

 blue grass is now im- 

 portant. Blue grass is 

 adapted to almost iden- 

 tically the same area as 

 timothy, though as a lawn 

 grass it is grown much 

 farther south. It thrives 

 especially on limestone 



soils, and it is such soils as these that constitute the 

 famous blue grass region of Kentucky. Blue grass 

 pasture is exceedingly palatable and live-stock prefer 

 it to nearly all other grasses. 



Bermuda Grass is a native of India, and is supposed 

 to have been introduced into this country in 1812. It 

 now occurs throughout the Southern States and thrives 

 fairly well as far north as Washington, D. C., and 

 Central Kansas. It requires hot summer weather, and 

 grows then with great rapidity on good soil, reaching a 

 height of 1 8 inches. It makes a dense mass so that
