viii. APPENDIX. 



The produce of this grass is greater than its ap- 

 pearance would denote; the leaves seldom attain to 

 more than four or five inches in length, and the flower 

 stalks seldom arise to more. Its growth is not rapid 

 after being cropped, nor does it seem to withstand 

 the effects of frost, which if it happen to be severe 

 and early in the spring, checks it so much as to pre- 

 vent it from flowering for that season; otherwise the 

 quantity of nutritive matter which the grass affords 

 (for the straws are very inconsiderable,) would rank 

 it as a valuable grass for permanent pasture.
