One of the four cows originally imported into this country by John P. Cushing, Esq., of Massachusetts, gave in one year three thousand eight hundred and sixty-four quarts, beer measure, or about nine hundred and sixty-six gallons, at ten pounds the gallon; being an average of over ten and a half beer quarts a day for the entire year. The first cow of this breed, imported by the Massachusetts Society, for the Promotion of Agriculture, in 1837, yielded sixteen pounds of butter a week for several successive weeks, on grass feed only. It should be borne in mind, in this connection that the climate of New England is less favorable to the production of milk than that of England and Scotland, and that no cow imported after arriving at maturity can be expected to yield as much, under the same circumstances, as one bred on the spot where the trial is made, and perfectly acclimated. On excellent authority, the most approved shape and marks of a good dairy cow are as follows: Head small, long, and narrow toward the muzzle; horns small, clear, bent, and placed at considerable distance from each other; eyes not large, but brisk and lively; neck slender and long, tapering toward the head, with a little loose skin below; shoulders and fore quarters light and thin; hind quarters large and broad; back straight, and joints slack and open; carcass deep in the rib; tail small and long, reaching to the heels; legs small and short, with firm joints; udder square, but a little oblong, stretching forward, thin skinned and capacious, but not low hung; teats or paps small, pointing outward, and at a considerable distance from each other; milk-veins capacious and prominent; skin loose, thin, and soft like a glove; hair short, soft, and woolly; general figure, when in flesh, handsome and well proportioned. If this description of the Ayrshire cow be correct, it will be seen that her head and neck are remarkably clean and fine, the latter swelling gradually toward the shoulders, both parts being unencumbered with superfluous flesh. The same general form extends backward, the fore quarters being, light the shoulders thin, and the carcass swelling out toward the hind quarters, so that when standing in front of her it has the form of a blunted wedge. Such a structure indicates very fully developed digestive organs, which exert a powerful influence on all the functions of the body, and especially on the secretion of the milky glands, accompanied with milk-veins and udder partaking of the same character as the stomach and viscera, being large and capacious, while the external skin and interior walls of the milk-glands are thin and elastic, and all parts arranged in a manner especially adapted for the production of milk.
