The proportional value which the grass at the

 ripe, is as 6 to 9.

The proportional value which the whole of the 

 latter- math crop bears to that at the time the seed is 

 ripe, is as 5 to 9, and to that at the time flowering, 

 proportionably as 13 to 24. 



The above statement clearly shews that there is 

 nearly three-fourths of produce greater from a clayey 

 loam than from a sandy soil, and the grass from the lat- 

 ter is comparatively of less value, in proportion as 4 

 to 6. The straws produced by the sandy soil are defi- 

 cient in number and in every respect less than those 

 from the clayey loam; which will account for the un- 

 equal quantities of nutritive matter afforded by them; 

 but the proportional value in which the grass of the 

 latter-math exceeds that of the crop at the time of 

 flowering, is as 4 to 3; a difference which appears 

 extraordinary, when the quantity of flower-stalks 

 which are in the grass at the time of flowering is 

 considered. In the Anthoxanthum odoratum the pro- 

 portional difference between the grass of these crops 

 is still greater, nearly as 4 to 9 ; in the Poa fratensis 

 they are equal; but in all the latter flowering grasses 

 experimented upon, the flowering straws of which
