Rocky Mountains, where it is now cultivated almost 

 to the exclusion of other forage plants. 



" Alfalfa is a deep feeder. The tap roots descend 

 to gjeat depths wherever the soil is loose and per- 

 meable, often averaging ten to twelve feet. It has 

 been recorded as sending its roots to the depth of 

 fifty and sixty-six feet. 



" When the stems are cut or grazed off, the stalk 

 dies down to the very base, and new buds spring 

 up on the upper part of the crown of the new root 

 and grow, forming new stems. This method of 

 growing explains why so many farmers have re-" 

 ported that alfalfa is injured or destroyed by con- 

 tinuous close grazing. Prime condition for success 

 is that the land be well drained. Twenty to twenty- 

 five pounds of seed per acre broadcast. Fifteen to 

 twenty pounds in drills."
