Mr. Aiton, of Scotland, gives the following account of them. "The dairy breed of Scotland have been formed chiefly by skilful management, within the last 50 years; and they are still improving and extending to other countries. Till after 1770, the cows in Cunningham were small, ill-fed, ill-shaped, and gave but little milk. Some cows of a larger breed and of a brown and white color, were about that time brought to Ayrshire from Teeswater, and from Holland, by some of the patriotic noblemen of Ayrshire; and these being put on good pasture, yielded more milk than the native breed, and their calves were much sought after by the farmers." We may fairly infer from the foregoing, which is deemed indisputable authority; from the locality of their origin, in the neighborhood of the Short Horns; and from their general resemblance, both externally and in their general characteristics to the grade animals, that they owe their principal excellence to this long-established breed. MANAGEMENT OF CALVES. The safest and least troublesome manner of raising calves, is at the udder of the dam; and whenever the milk is converted into butter and cheese, we believe this to be the most economical. The milk of one good cow is sufficient, with a run of fresh, sweet pasture, to the feeding of two calves at the same time; and if we allow the calves to arrive at three or four months of age before weaning, we may safely estimate, that one good cow will yield a quantity of milk in one season, fully equivalent to bringing up four calves to a weaning age. By keeping the calf on the fresh milk, whether he take it directly from the udder, or warm from the pail, all risk of disordered bowels is avoided. The milk is precisely adapted to the perfect health and thrift of the young, and whenever we substitute for it any other food, we must watch carefully that not the slightest mismanagement produces disorder, lest more is lost by disease or want of improvement, than is gained by the milk of which they are robbed. The first milk of the cow after calving, is slightly purgative, which is essential to cleanse the stomach of the calf. It is, moreover, perfectly worthless for two or three days, for any other purpose except for swine. The calf will seldom take all the milk at first, and whatever is left in the bag should be thoroughly removed by the hand. If the calf is destined for the butcher, he must have all the milk he wants for at least six weeks, and eight or ten is better; and if the cow does not furnish enough, he ought to be fed gruel or linseed tea. He must be closely confined in a snug, but clean and airy stable, and the darker this is, and the more quiet he is kept, the more readily he will fatten.
