It is highly probable that this greiss 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.
