From a poor sandy soil, destitute of manure, the produce, at 



the time of flowering, is 



Grass, 16 oz. The produce per acre - 10890 



64 dr. of grass afford of nutritive matter 80 gr. 453 12 



From a moist clayey soil, without manure, the produce, at 



the time of flowering, is 



Grass 12 oz. The produce per acre 8167 8 



64 dr. of grass afford of nutritive matter 69 gr. 293 8 5 



From a rich black loam, at the time of flowering, the pro- 

 duce is 



Grass, 14 oz. 8 dr. The produce per acre - 9869 1 



64 dr. of grass afford of nutritive matter 90 gr. 462 912 



From the above details, it appears that the weight of nutritive 

 matter which is lost by taking the crop at the time of flowering, 

 exceeds one-seventh part of its value ; and the nutritive matter 

 contained in the grass of the seed crop, exceeds that in the 

 flowering grass, in the proportion of 13 to 11, and that of the 

 latter-math as 13 to 8. 



The results of the experiments on the three different soils now 

 mentioned shew this grass to be best fitted for poor soils, and 

 afford one instance, that manure is even hurtful to some grasses. 

 Its nutritive powers are considerable, when compared to other 

 grasses affecting a similar soil. It is eaten by horses, cows, and 

 sheep. These merits, therefore, demand attention, and though 

 it is unfit, comparatively, for rich permanent pasture, yet, for 

 poor sandy, and also for poor tenacious soils, where improvement 

 in other respects cannot be sufficiently effected to fit them for the
