She seems in all cases to have had a special interest in the cows and the dairy, and to have resented any want of recognition of her services. A portion of milk was set apart for her every evening, in a hole for the purpose in some convenient stone, and unless this was done, something was found amiss in the dairy next morning. Others left milk for her only when leaving the summer pastures for the season. She was seldom seen, oftenest when anything was to happen to the house she followed. She might then be seen, making her way in the evening up the slope to the castle, herding the cattle on the pastures, sunning herself on the top of a distant rock, or coming to the fold at dusk for her allowance of milk. Her cries, and the noise she made, arranging the furniture, shouting after the cattle, or at the approach of joy or sorrow, were frequently heard. In the south Highlands, the Glaistig was represented as a little wan woman, stout and not tall, but very strong. In Skye, where most of her duties were assigned to a male deity, the _Gruagach_, she was said to be very tall, ‘a lath of a body’ like a white reflection or shade. Her name is derived from _glas_, grey, wan, or pale-green, and _stìg_, a sneaking or crouching object, probably in allusion to her invisibility, noiseless motions, or small size. In the _Highland Society’s Dictionary_, she is called “a she-devil, or hag, in the shape of a goat,” and the definition is accepted by M‘Leod and Dewar. This, however, is a mistake. The shape of a goat, in the Highlands as elsewhere, has been assigned to the devil only, and there was nothing diabolical, or of the nature of an evil spirit, seeking the perdition of mankind, ascribed to the poor Glaistig. She occupied a middle position between the Fairies and mankind; she was not a Fairy woman (_Bean shìth_) but one of human race, who had a Fairy nature given to her. The Fairies themselves are much nearer in character to the race of man than to that of devils. Of course all unearthly beings are to be avoided, but of all the beings, with which fear or fancy has peopled the unseen world, the Glaistig and her near relation the Brownie are among the most harmless.
