affected by the time occupied in washing. It shows, however, that the cob is not by any 
means destitute of value ; and that the practice of many farmers, of grinding the cob with 
the corn for feeding stock, is the most economical way of disposing of it. There is still 
another reason for the practice, namely, to increase the bulk of the food; for it is unsafe 
to feed concentrated nourishment to herbivorous animals. They require a bulky food, 
for the purpose of effecting a moderate distension of the alimentary canal; and hence if 
the cob was less nutritive than is here represented, it would still be the proper plan to be 
pursued in feeding cattle or horses, though not so necessary to the latter as to the former. 
It will be observed particularly that the nitrogenous compounds amount to 2*58, and 
the gum, sugar, extract and oil, to 9‘46; and if the 86 per centum of insoluble matter 
had been subjected to the action of fluids equal in solvent power to the gastric juice, this 
would still have been diminished some four or five per centum.

*This variety, before ripening, was supposed to be the Pennsylvania Dent. It has the red cob of the Tuscarora, and 
about i of the kernels were of this kind.
