In selecting any breed, regard should be had to the circumstances of the individual farmer and the object to be pursued. The cow most profitable for the milk dairy, may be very unprofitable in the butter and cheese dairy, as well as for the production of beef; while, for either of the latter objects, the cow which gave the largest quantity of milk might be very undesirable. A union and harmony of all good qualities must be secured, so far as possible. The farmer wants a cow that will milk well for some years; and then, when dry, fatten readily and sell to the butcher for the highest price. These qualities, often supposed to be utterly incompatible, will be found united in some breeds to a greater extent than in others; while some peculiarities of form have been found, by observation, to be better adapted to the production of milk and beef than others. It is proposed, therefore, to sketch the pure breeds now found in America. THE AYRSHIRE. [Illustration: AN AYRSHIRE BULL.] This breed is justly celebrated throughout Great Britain and this country for its excellent dairy qualities. Though the most recent in their origin, they are pretty distinct from the Scotch and English races. In color, the pure Ayrshires are generally red and white, spotted or mottled, not roan like many of the short horns, but often presenting a bright contrast of colors. They are sometimes, though rarely, nearly or quite all red, and sometimes black and white; but the favorite color is red and white brightly contrasted; and, by some, strawberry-color is preferred. The head is small, fine and clean; the face long and narrow at the muzzle, with a sprightly, yet generally mild expression; eye small, smart and lively; the horns short, fine, and slightly twisted upward, set wide apart at the roots; the neck thin; body enlarging from fore to hind quarters; the back straight and narrow, but broad across the loin; joints rather loose and open; ribs rather flat; hind quarters rather thin; bone fine; tail long, fine, and bushy at the end; hair generally thin and soft; udder light color and capacious, extending well forward under the belly; teats of the cow of medium size, generally set regularly and wide apart; milk-veins prominent and well developed. The carcass of the pure bred Ayrshire is light, particularly the fore quarters, which is considered by good judges as an index of great milking qualities; but the pelvis is capacious and wide over the hips. On the whole, the Ayrshire is good looking, but wants some of the symmetry and aptitude to fatten which characterize the short horn, which is supposed to have contributed to build up this valuable breed on the basis of the original stock of the county of Ayr, which extends along the eastern shore of the Firth of Clyde, in the southwestern part of Scotland.
