We have learned that nitrogen is the principal ingre- dient in protein, the feed most sought after by the pro- gressive farmer. From an examination of the table, we find that clover hay is richer in protein than any cows IN A CLOVER FIELD. other kind of hay. A little calculation shows us that it contains about twice as much protein as redtop, three times as much as timothy, eight times as much as oat straw, fifteen times as much as rye straw, and thirty times as much as wheat straw. On average land a larger amount of clover, or some other legume adapted to the soil, can be grown per acre than of any other hay crop, and, since it adds nitrogen to the soil, it is by far the best hay crop to raise. Corn.—Another examination of the table reveals the fact that corn is one of the richest of grains, and since corn is one of the richest of fodders in feeding
