GLUMES of the Calyx compofed of two valves, which 

 are unequal, pointed, and have the keel, or 

 rib on the back, rough, fig. 4. If the glumes 

 of the corolla are drawn out of the glumes of 

 the calyx, a wooly fubftance (fig. 9,) is ob- 

 fervable, and which, as far as I have hitherto 

 noticed, is peculiar to this Grafs and the 

 Poa pratenfis.

THE means of diftmgmfhmg this Grafs from the Poa pratenfis, (for which it is the moft liable to be miftaken) 

 with many other particulars relative to it, we have already given under the latter : confidered in an agricultural 

 light, it is certainly one of our beft grafles, both for hay and pafturage ; indeed a good meadow can fcarcely be 

 lormea without it Its chief qualities are, that it produces a large quantity of fweet tender leaves, which are 

 preferred by cattle to moft others, and which are convertible into exceeding fine hay. It is an early grafs,* 

 flowering about the beginning of June. It does not bear the frofts of the Winter fo well, nor does it moot 

 lo early in the Spring as the Poa pratenfis-, but when the weather comes to be fo warm as to make the grafles 

 thaxTmoft othe ^^ *' ^ pr ° dllCeS a & reater cro P of bottom leaves > ( the moft defirable- parts of grafles,) 



It grows belt in meadows that are tolerably moift : in dry paftures it is often found, but much fmaller 



Hints relative to the Culture of the Grqffes. 



When the advantages refulting to the community from the introduction of Wheat, Barley, Rye, Clover, tares, 

 at. torn, Irejoil ' & c . many of which are natives of our own country, daily occur to us: when neither pains 

 nor expence are ipared to improve our arable lands, it feems ftrange that fo little care mould be taken of the 

 improvement of our meadows and paftures, which might doubtlefs be made to produce double or treble the crops 

 they already do, by the judicious introdudion of proper grafles.
