This is one of the finest grasses on the prairie for hay or pasture. 

 It seems to prefer saline and damp soil, and does not grow in bunches 

 but singly. There are numerous forms of this which are generally 

 refei-red to the next, but which I include here. Sir John Eichardson 

 seems to have found the species all the way to the Arctic sea.
