The belief in the existence of the Water-horse is now in the Highlands generally a thing of the past, but in olden times almost every lonely freshwater lake was tenanted by one, sometimes by several, of these animals. In shape and colour it resembled an ordinary horse, and was often mistaken for one. It was seen passing from one lake to another, mixing with the farmers’ horses in the adjoining pastures, and waylaid belated travellers who passed near its haunts. It was highly dangerous to touch or mount it. Those whom it decoyed into doing so were taken away to the loch in which it had its haunt, and there devoured. It was said to make its approaches also in other guises—as a young man, a boy, a ring, and even a tuft of wool (_ribeag clòimhe_); and any woman upon whom it set its mark was certain at last to become its victim. The cow-shackle round its neck, or a cap on its head, completely subdued it, and as long as either of these was kept on it, it could be as safely employed in farm labour as any other horse. In Skye it was said to have a sharp bill (_gob biorach_), or, as others describe it, a narrow brown slippery snout. Accounts are uniform that it had a long flowing tail and mane. In colour it was sometimes grey, sometimes black, and sometimes black with a white spot on its forehead. This variation arose, some say, from the water horse being of any colour like other horses, and others say from its having the power of changing its colour as well as its shape. When it came in the shape of a man, it was detected by its horse-hoofs and by the green water weeds or sand in its hair. It was then very amorous, but the end of those who were unfortunate enough to encounter it was to be taken to the loch and devoured. However much benefit the farmer might at first derive from securing one with the cap or cow-shackle he was ultimately involved by it in ruinous loss. The following tales will illustrate the character of the superstition better than a lengthened dissertation: FARMERS AND WATER-HORSES. Stories to the following effect are common in Mull and the neighbourhood:
