The former, whom, like the Scots, they also term the _guid folk_ and _guid neighbours_, they conceive to inhabit the interior of green hills. Persons who have been brought into their habitations have been dazzled with the splendour of what they saw there. All the interior walls are adorned with gold and silver, and the domestic utensils resemble the strange things that are found sometimes lying on the hills. These persons have always entered the hill on one side and gone out at the other. They marry and have children, like their northern kindred. A woman of the island of Yell, who died not long since, at the advanced age of more than a hundred years, said, that she once met some fairy children, accompanied by a little dog, playing like other boys and girls, on the top of a hill. Another time she happened one night to raise herself up in the bed, when she saw a little boy with a white nightcap on his head, sitting at the fire. She asked him who he was. "I am Trippa's son," said he. When she heard this, she instantly _sained_, i. e. blessed herself, and Trippa's son vanished. _Saining_ is the grand protection against them; a Shetlander always sains himself when passing by their hills. The Trows are of a diminutive stature, and they are usually dressed in gay green garments. When travelling from one place to another they may be seen mounted on bulrushes, and riding through the air. If a person should happen to meet them when on these journeys, he should, if he has not a bible in his pocket, draw a circle round him on the ground, and in God's name forbid their approach. They then generally disappear.[227] They are fond of music and dancing, and it is their dancing that forms the fairy rings. A Shetlander lying awake in bed before day one morning, heard the noise of a party of Trows passing by his door. They were preceded by a piper, who was playing away lustily. The man happened to have a good ear for music, so he picked up the tune he heard played, and used often after to repeat it for his friends under the name of the Fairy-tune. The Trows are not free from disease, but they are possessed of infallible remedies, which they sometimes bestow on their favourites. A man in the island of Unst had an earthen pot that contained an ointment of marvellous power. This he said he got from the hills, and, like the widow's cruise, its contents never failed. They have all the picking and stealing propensities of the Scandinavian Trolls. The dairy-maid sometimes detects a Trow-woman secretly milking the cows in the byre. She sains herself, and the thief takes to flight so precipitately as to leave behind her a copper pan of a form never seen before.
