It is highly probable that this grass had passed its mature state, and that its stem had 
become drier and more ligneous than when in blossom, and hence the per centum of silica 
is large when compared with that of the Red-top. This grass, in consequence of its early 
maturity, becomes dry and hard when left standing till timothy is ripened.
