Chief among the domesticated sheep of the British Isles is the Southdown, whose characteristics used to be--although we are told they are changed somewhat now--thin chine, low fore-end, and rising backbone, a small hornless head, speckled face, thin lips, woolled ears, and bright eyes. The wool should 'be short, close, curled, fine, and free from spiry projecting fibres.' Then there are the Romney Marsh, the Cotswold, the Lincoln, the Leicester, and the Hardwick sheep, each with its distinctive marks and value. The Welsh sheep have long necks, high shoulders, narrow breasts, long bushy tails, and small bones; the wool is not first class, but the mutton is excellent. The Irish native sheep are of two kinds, the short-woolled and long-woolled; but Southdowns and Leicesters have been so long crossed with them that their idiosyncrasies are no longer marked. The Shetland sheep are supposed to have come from Denmark, but have also been crossed with English and Scotch varieties. In Scotland, the Cheviot and the Blackfaced are the two ruling types. The Cheviot is a very handsome animal, with long body, white face, small projecting eyes, and well-formed legs. The wool is excellent, as the 'tweed'-makers of the Border know, but is not so soft as that of the English Southdowns. The Blackfaced is the familiar form we see in the Highlands, supposed to have come originally 'from abroad,' but now regarded as the native sheep of Scotland. It is a hardy animal, accustomed to rough food and rough weather, with a fine deep chest, broad back, slender legs, attractive face, and picturesque horns. The wool is not so good as that of the Cheviot variety, but the mutton is better. Of course, English varieties have been largely crossed with the two native Scotch kinds; yet these still remain distinct, and are easily recognisable.
