The proportional value which the grass at the time 
the seed is ripe, bears to that at the time of flowering, 
is as 14 to 18. 
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.
