iho autumn. The plant, in this state of combination, takes 

 but little from the soil. 



In covnparing the produce and nutritive powers of 

 different grasses, to arrive at a knowledge of their relative 

 value, it is absolutely necessary, for the truth of comparison, 

 that the produce of one whole season be taken, and not one 

 crop singly, except in instances where the produce consists 

 but of one crop only. Accordingly, the produce of florin 

 may be compared with that of the cock's-foot grass ( dad y lis 

 glomerata), meadow fescue (J'estiica pratensis), and the 

 meadow fox-tail (alopecurus pratensis), when it will appear 

 infeiior to the two former species, and superior to the latter. 

 On referring to former details it appears, that 



The agrostis stolouifera, var. /f/^//o/«o, larger creeping-bent, 

 taken in December, affords of nutritive matter 1,405 lbs, per 

 acre in one year. 



The dacti/lis glumerala, cock's-foot ^^r^sfi, l,7281bs. per acre. 



The fcstnca pratensis, meadow fescue, 1,719 lbs. per acre. 



The alopecurus pratensis, meadow fox- tail, 1,216 lbs. per 

 acre. 



The cock's-foot grass, under the circumstances described, 

 is therefore superior to the larger variety of the creeping-bent, 

 in the proportion, nearly, of 1 1 to 9. 



The meadow fescue (festuca pratensis) is also superior to 

 florin, in nearly the like proportion as cock's-foot. 



The meadow fox-tail-grass (alopecumis pratensis) is inferior 

 to florin, in the proportion, nearly, of 6 to 7. 



Though the quantity of nutritive matter afforded by a 

 grass in one whole season, is the chief property by which its 

 comparative value can be determined, yet the particular 

 season or seasons in which it is produced, the nature of the 

 soil on which it cai/ be cultivated to most advantage, and 

 the superior facilities its peculiar habits of growth afford for 

 its propagation, as also for reaping its produce, are points 

 which must necessarily be taken into the account by the 

 agricultuiist, according as they arc influenced by iocal 

 circumstances, such as the nature of the soil, and situation 

 of his farm.
