Previously to the enormous development of the urban trade in country milk, dairy farms were in the main self-sustaining in the matter of manures and feeding-stuffs, and the cropping of arable land was governed by routine. To-day, on the contrary, many dairy farms are run at high pressure by the help of purchased materials,--corn, cake, and manure,--and the land is cropped regardless of routine and independent of courses. Such crops, moreover, are grown--white straw crops, green crops, root crops--as are deemed likely to be most needed at the time when they are ready. Green crops,--"soiling" crops, as they are termed in North America,--consisting largely of vetches or tares (held up by stalks of oat plants grown amongst them), cabbages, and in some districts green maize, are used to supplement the failing grass-lands at the fall of the year, and root crops, especially mangel, are advantageously grown for the same purpose. For winter feeding the farm is made to yield what it will in the shape of meadow and clover hay, and of course root crops of the several kinds. This provision is supplemented by the purchase of, for example, brewers' grains as a bulky food, and of oilcake and corn of many sorts as concentrated food.
