The proportional value which the grass at the 

 time the seed is ripe, bears to that at the time of flower- 

 ing, is as 1 4 to 1 8. 



The above details prove this grass to have merits 

 which, if compared with those of other species, rank 

 it with some of the best grasses. The small loss of 

 weight which it sustains in drying might be expected 

 from the nature of the substance of the grass; and the 

 loss of weight at each period is equal. The grass 

 affords the greatest quantity of nutritive matter when 

 in flower, which makes it rank as one of those best 

 adapted for hay.
