According to folklore, there is no doubt that rivers are "uncanny." Beneath their rippling surface dwells a being who keeps a lookout for the unwary traveller and seeks to draw him into the dark depths. A belief in such a being is not always explicitly avowed. But there are certain folk-practices undoubtedly implying it. When anyone is drowned in a river, the natural way to find the body is to drag the stream in the neighbourhood of the accident. But superstition has recourse to another method. A loaf of bread, with or without quicksilver in it, is placed on the surface of the water and allowed to drift with the current. The place where the loaf becomes stationary marks the spot where the body lies concealed. According to another method, a boat is rowed up and down the stream, and a drum is beat all the time. When the boat passes over the resting place of the body the drum will cease to sound. This was done in Derbyshire no longer ago than 1882, in order to find the corpse of a young woman who had fallen into the Derwent. In such practices there is a virtual recognition of a water-spirit who can, by certain rites, be compelled to give up his prey, or at any rate to disclose the whereabouts of the victim. A Deeside tradition supplies a good illustration of this. A man called Farquharson-na-Cat, i.e., Farquharson of the Wand, so named from his trade of basketmaking, had on one occasion to cross the river just above the famous linn. It was night. He lost his footing, was swept down into the linn, and there drowned. Search was made for his body, but in vain. His wife, taking her husband's plaid, knelt down on the river's brink, and prayed to the water-spirit to give her back her dead. She then threw the plaid into the stream. Next morning her husband's corpse, with the plaid wrapped round it, was found lying on the edge of the pool. Till quite lately, fishing on the Tweed was believed to be influenced by the fairies of the river. Salt was thrown into the water, and sprinkled on the nets to insure a plentiful catch of fish. This was really the offering of a sacrifice to the river-spirits.
