of flowering, is - 436 7 



The nutritive matter contained in the grass at the time the seed is 



ripe, exceeds that in the grass at the time of flowering, in the 



proportion of 5 to 3.

The proportional value which the grass of the latter-math bears 

 to that at the time of flowering, is as 3 to 6 ; and to the grass at 

 the time the seed is ripe, as 3 to 10. 



In regard to early growth, this grass stands next to the meadow 

 fox-tail, cock's-foot, and tall oat. The herbage is more nutritive 

 than that of either of these grasses. It will appear remarkable, 

 that the grass of the latter-math should contain more nutritive
