 As, however, in the milling, nearly one-sixth of the cotyledon 

 still adheres to the grain, lor all practical estimates, it will be 

 nearer the truth to state the mineral ingredients of clean rice at 2 

 per cent those of the whole crop, and to diminish, therefore, the 

 residuum of the cotyledon and epidermis by 0.06 per cent, 

 making the percentage statement to stand thus : 



Stubble and root, 36 . 08 



Straw and leaves, 36 . 08 



Husk, 14.20 



Cotyledon and epidermis, 11 .64 



Clean rice, (commercial,) 2 . 00

 [9. J If the foregoing views are correct, it becomes plain, at a 

 glance, that the planter who sells his crop in the condition of rough 

 rice, robs his lands of 27.84 per cent of the mineral ingredients 

 of this species of produce ; while, on the other hand, he who sells 

 it as clean rice, subtracts from them but two per cent of these 

 ingredients. 



But the true value of these constituents cannot be rightly esti- 

 mated by their numerical proportions, since the mineral ingredients 

 of the cotyledon and epidermis consist of above fifty per cent of 

 the most precious saline substances, while in those of the stubble, 

 root and husk, the like constituents scarcely rise to ten per cent. 



[lO.j From the extreme slowness with which the husk sutfers 

 conversion into humus, unless fermented with stable litter, this 

 portion of the rice plant appears to be almost wholly neglected by 

 the planter. But as it contains above thirty per cent of carbon, 

 it mu«;t be capable, when incorporated with the soil, of performing, 

 to a considerable extent, the functions of humus, i. e. of gradually 

 giving rise to carbonic acid from combining with the oxygen of 



• It may be useful to present here, also, a per centum view of the incombustible 

 constituents of the rough rice. 



Husk, 51.00 



Cotyledon and epidermis, 41 .81 



Clean rice, 7.19 



It scarcely need to be stated, that the cotyledon and epidermis are found in the 

 coarse rice flour, intermingled larg-ely with the husk, and witli from three to four per 

 cent of powdered clean rice. The cotyledon and the epidermis are richer than the 

 clean rice in saccharine matter and gluten, which materially augment the value of 

 rice flour as a feed for cattle and swine. These principles are tlius returned to the soil 

 unilcr the most favorable conditions for agriculture.
