Western Isles of Scotland.
Martin, in his Account of the Western Islands of Scotland (1703, p. 7), speaking of the Isle of Lewis, says that the natives in the village Barvas retain an ancient custom of sending a man very early to cross Barvas river every first day of May, to prevent any females crossing it first; for that they say would hinder the salmon from coming into the river all the year round. They pretend to have learned this from a foreign sailor, who was shipwrecked upon that coast a long time ago.
