About twenty years ago, a house in Kilmoluag, Tiree, was the scene of similar disturbances [to those at Bonskeid]. With one or two exceptions, all the people of the island believed them to be produced by some supernatural evil agency, and all the superstition that with the spread of education had been quietly dying out was revived in renewed vigour. No one could deny the agency of spirits when the evidence was so clear. The annoyance began by the trickling of dirty water, mixed with sand, from the roof. The burning peats were found among the bedclothes, and pebbles in bowls of milk, where no peats or pebbles ought to be; linen was lifted mysteriously from the washing, and found in another room; articles of furniture were moved without being touched by visible hands, and stones flew about the house. The disturbances did not occur during the day, nor when a large company assembled at the house. Several went to lay the ghost, and a good deal of powder and shot was wasted by persons of undoubted courage in firing in the air about the house. The annoyance became so bad, and the advice of “wise people” so positive, that the family removed to another house, in the hope the evil would not follow. The removal, however, had no effect, and it is privately rumoured, the disturbances ceased only when some money that had gone amissing was restored. The cause was never clearly ascertained, but there is reason to suspect it was caused, as all similar disturbances are, by some one suborned for the purpose and shielded from suspicion by a pretended simplicity and terror.
