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.
When they want beef or mutton on any festal occasion, they betake themselves to the Shetlanders' scatholds or town-mails, and with elf-arrows bring down their game. On these occasions they delude the eyes of the owner with the appearance of something exactly resembling the animal whom they have carried off, and by its apparent violent death by some accident. It is on this account that the flesh of such animals as have met a sudden or violent death is regarded as improper food.
A Shetlander, who is probably still alive, affirmed that he was once taken into a hill by the Trows. Here one of the first objects that met his view was one of his own cows, that was brought in to furnish materials for a banquet. He regarded himself as being in rather a ticklish situation if it were not for the protection of the Trow-women, by whose favour he had been admitted within the hill. On returning home, he learned, to his great surprise, that at the very moment he saw the cow brought into the hill, others had seen her falling over the rocks.
Lying-in-women and "unchristened bairns" they regard as lawful prize. The former they employ as wet-nurses, the latter they of course rear up as their own. Nothing will induce parents to show any attention to a child that they suspect of being a changeling. But there are persons who undertake to enter the hills and regain the lost child.
A tailor, not long since, related the following story. He was employed to work at a farm-house where there was a child that was an idiot, and who was supposed to have been left there by the Trows instead of some proper child, whom they had taken into the hills. One night, after he had retired to his bed, leaving the idiot asleep by the fire, he was suddenly waked out of his sleep by the sound of music, and on looking about him he saw the whole room full of fairies, who were dancing away their rounds most joyously. Suddenly the idiot jumped up and joined in the dance, and showed such a degree of acquaintance with the various steps and movements as plainly testified that it must have been a long time since he first went under the hands of the dancing-master. The tailor looked on for some time with admiration, but at last he grew alarmed and sained himself. On hearing this, the Trows all fled in the utmost disorder, but one of them, a woman, was so incensed at this interruption of their revels, that as she went out she touched the big toe of the tailor, and he lost the power of ever after moving it.[228]
In these cases of paralysis they believe that the Trows have taken away the sound member and left a log behind. They even sometimes sear the part, and from the want of sensation in it boast of the correctness of this opinion.[229]
