A comparison will shew, how inferior this smaller variety of Meadow Cat's-tail grass is to 

 the larger variety.

The smaller variety of Meadow Cat's-tail grass affords, from the produce of one acre at the

Or, the former grass is superior to this one, in the proportion nearly ^f 25 to 8. Tii 

 shews how important a point it is to distinguish one variety of grass from another, when they 

 are so very much alike in outward characters, as in the above instance. The seeds are also 

 very snmlar to each other, or rather the marks which distinguish them from each other,

 spring, than the larger variety, and it is much less nutritive
