 The weight of nutritive matter which is lost, by taking 

 the crop at the time of flowering, exceeding one- 

 sixth of its value, is 71 12 9 



The proportion in which the grass at the time of flowering 

 exceeds that at the time the seed is ripe, with respect to nutritive 

 powers, is as 17 to 10, and is superior to the latter-math in the like 

 proportion. 



The quantity of grass at the time the seed is ripe, is just twice 

 that at the time of flowering ; but the grass at the former period 

 contains nearly twice the quantity of nutritive matter, as appears 

 above ; and when the latter-math, which would be produced during 

 the time the seed was ripening, is added to this, it shews the su- 

 perior advantage of taking the crop when the grass is in flower. 

 The culms of this grass are of a wiry nature, and, at the time the 

 seed is ripe, contain no nutritive matter. The leaves are rather 

 slow in growth, are short, but form a dense turf ; hence, the weight 

 of grass at the time the seed is ripe, is greater than at the time of 

 flowering, but contains proportionally less nutritive matter. It is
