 the root fibrous ; the awns are also much longer than those of the awned variety of common

The crop, at the time of flowering, is therefore of greater proportional value than that at the time the 



seed is ripe, nearly as 6 to 5.

From tlie above facts it appears, that this grass is of considerable value, more particularly 

 as it affords herbage early in the spring, in a degree superior to Rye-grass, Sweet-scented 

 Vernal, and nearly equal to the Meadow Fox-tail. It produces a sufficiency of seed, which 

 vegetates quickly, and the plants soon arrive at perfection in almost every kind of soil, except 

 in such as are tenacious or retentive of moisture. If to these valuable properties it added late 

 growth, or a proportional supply of latter-math, it would rank high among the superior, 

 grasses j but in this it is deficient, as are most of the grasses which produce early foliage in the 



tions, properly, to this point.
