(14.) _Mugg Sheep._--"In this variety," says Dr Fleming, in his History of British Animals, "the face and legs are white, or rarely spotted with yellow, and the forehead covered with long wool. This is the native breed in Scotland, to the north of the Forth and Clyde. They are of small size, and seldom weigh above 8 or 10 lbs. per quarter. Some tribes have horns; others are destitute of them, and they vary in the length of the tail. They may be considered as the stock of the numerous modern and valuable varieties, which are bred in the best cultivated districts. The Shetland sheep belongs to this kind. The fur consists of firm wool next the skin, with long coarse hairs, indications of an inhabitant of an arctic climate." (15.) _The Black-faced or Heath Sheep_ are known by their large spiral horns, wild-looking eyes, black legs and faces, with short firm carcasses, covered by long coarse wool, which weighs from 3 lbs. to 4 lbs. As the form of this sheep has lately been much improved, by inducing a short and round carcass, they have acquired the name of _short_ sheep, in contradistinction to the Cheviots, which are termed long sheep. When three years old, they fatten well, affording excellent highly-flavoured mutton, and weighing from 10 lbs. to 16 lbs. a-quarter. They are the most valuable upland sheep in Britain, abounding in all the western counties of England and Scotland, and are now becoming great favourites in the London market. Fig. 1. Pl. IV. (16.) _The Merino._--Though many foreign breeds have from time to time appeared in this country, yet almost all of them have been viewed merely as objects of curiosity, and, as such, have speedily been disregarded. Far different, however, was the reception of the Merinos. Brought into England under the most favourable auspices, and placed at once under the fostering protection of royalty, their native merits could not but be speedily appreciated and diffused throughout the kingdom. They have received the name of _Merino_ from a peculiar buff or reddish hue of the countenance, and are supposed to have come originally from Africa; at least Marcus Columella, having seen a strange variety from that country exhibited at Rome, during some public games or shows, took them to his farm, and, having crossed them with the breeds of Tarentum, sent the offspring to Spain. There they throve remarkably, attracting the attention of other nations, to whom they were from time to time exported, and at present may be found in almost every part of the world.
