 The weight of nutritive matter which is lost by taking the 

 crop at the time of flowering, being nearly one-fourth 

 part of its value 109 1 



The proportional value which the grass at the 

 time of flowering, bears to that at the time the seed is 

 ripe, is as 1 1 to 13.

The proportional value in which the grass at the 

 time of flowering, exceeds that of the latter-math 

 is as 8 to 11; and the latter-math stands to that at the 

 time the seed is ripe in proportion as 8 to 13. 



The merits of this grass seem to demand notice ; 

 its nutritive powers are considerable, and its produce
