Hence the animal kingdom is dependent upon the \ potable kingdom for its ei isten< .

Sin. Miinials consume plants for f I,

it follows that the same elements which

O O T in plants are found in the animal OU body. In fact the same compounds that occur in vegetable matter are again found in the animal body, only slightly moditied. Before chemistry began to shed its light upon agriculture y the rearing and feeding of domestic animals for human food and raiment was just as empirical as the production of plants. I t is true, as already stated, that simple observation led to many good methods in actual practise, but no intelligent reasons could be given for the methods. The subject of animal nutrition was taken up by scientific investigators with as much zeal and as careful study and experimentation as were expended on vegetable production, and the results and data, obtained are sufficient to warrant an intelligent use of the means at hand. The amount of time and labor expended in changing the rule-of-thumb methods of feeding domestic animals into a rational system is \ vy great taken in the aggregate.
