84 GRASSES AND HOW TO GROW THEM. 



aggressive character enables it to crowd other valuable 

 grasses ovtt of the permanence which ought to he re- 

 tained in the same. 



These two varieties of blue grass grow best in tem- 

 perate climates. They can stand much cold in win- 

 ter and also heat in summer without succumbing to 

 either, but they do not grow well in a dry climate or 

 under conditions too dry for the successful growth of 

 the common cereals. It is found at its best where the 

 rains are moderate and frequent throughout much of 

 the year. 



It is doubtless correct to say that blue grass is grown 

 more or less in every state and territory in the Union. 

 It would be equally correct to say that from the Missis- 

 sippi to the Atlantic it occupies more territory than 

 any other grass, and that in the greater portion of the 

 territory thus occupied it has been found more useful 

 in providing grazing than any other grass. The same 

 statement will apply with almost equal force to the 

 country westward from the Mississippi for a consider- 

 able distance, or until the areas are reached in which 

 the rainfall is light. From the line which forms the 

 eastward border of the area named imtil the Rocky 

 mountains are reached, and in the plains between the 

 mountains, as for instance, the bench lands in the Big 

 Bend country in Washington, the conditions are too 

 dry for the successful growth of blue grass. But in 

 the bench lands of the foot hills it is being found that 

 blue grass will yet fulfill a not imimportant mission. 

 This grass grows at its best in the United States in the 

 limestone soils of Keutuckj' and in the states lyiu"
