White wool being most esteemed, those lambs which are black or spotted are commonly led to slaughter. There are some places however where almost all the sheep are black; and white rams and ewes will frequently produce spotted lambs. In France there are only white, black, and spotted; in Spain there is a reddish kind, and in Scotland there are some of a yellow colour; but these varieties in colour are more accidental than the difference and variety of the breed, which notwithstanding only happens from the influence of climate and the difference of nourishment. SUPPLEMENT. I was favoured with the drawings of two Wallachian Sheep[J] (_fig. 24, 25._) by Mr. Colinson a Fellow of the Royal Society of London, whose horns are very different from ours, but I was never able to discover whether they were of the ordinary kind in Walachia or some accidental variety. [J] The annexed representations were taken from two of these living animals, the property of Mr. Clark; and as the likeness was strongly attended to, will be found more correct than the drawings copied in the works of our author. In Denmark, Norway, and in the northern part of Europe, the sheep are very indifferent; and it is customary there to improve the breed, to have rams frequently imported from England. In the islands near Norway the sheep are constantly left in the fields, and they are much larger and produce better wool than those who are attended by men. Pontopiddan asserts that those sheep which live in perfect liberty always sleep on that side of the island from whence the wind will blow the next day, and this is constantly attended to by the mariners. The Iceland sheep have larger and thicker horns than the common sheep of these climates; some of them have four or five horns, but this is not common, and when they find any so ornamented, they are sent to Copenhagen and sold at a high price as great rarities.
