son-in-law’s abode.[168.4] The mantles are obviously the wolf-skins, laid aside to enable their owners to appear in human form. {169} Wolves are of course not water-spirits, like swans or seals; but they obey the same law as that imagined for the latter. The man who seizes something which is at once the symbol of their supernatural character and the source of their power, renders them helpless and compels them to his will. The contest is in these cases one of trickery and determination, rather than of strength. The captures of Proteus and of Thetis, however, seem to have been effected by main force and a wrestler’s skill. This is often the case with the capture of mermaids in the west of Europe. Hugh Miller long ago translated into literature a local legend of Cromarty which told how John Reid captured on the shores of the Firth a mermaid, from whom he extracted as a ransom the grant of three wishes, including prosperity and union with the maiden of his choice.[169.1] Mermaid-stories thus agree with kelpie-stories and with those of Proteus and the spirit of the Jabbok in assigning victory to the strength and skill of the human wrestler. Water-spirits are not the only supernatural beings with whom men are represented in story as matching themselves. The Lushei clans of Assam believe in various demons that inhabit hills, streams and trees. They are called Huai, those inhabiting the water being known as Tui-huai, and those residing on the land as Rām-huai. A certain sacrifice, generally of a big sow, is offered to the Rām-huai. It is called Sakhua. One night, towards morning, it is related, a Rām-huai appeared to a man who had unwittingly neglected his Sakhua sacrifice. It came into the straw where he was sleeping and wrestled with him until daylight. Even then it followed him and wrestled with him again; nor does the man seem to have been loth. At last he conquered the Rām-huai, {170} who then told him that his Sakhua sacrifice was over-due; and he performed it at once. Sometimes the Rām-huai appears as a tiger and sometimes as a man. On this occasion he seems to have been in human form.[170.1]
