On the southern sea-coast, in Glamorganshire, the Cyhyraeth is sometimes heard by the people in the villages on shore passing down the channel with loud moans, while those dismal lights which forebode a wreck are seen playing along the waves. Watchers by the sea-shore have also heard its moan far out on the ocean, gradually drawing nearer and nearer, and then dying away; and when they thought it gone it has suddenly shrieked close to their startled ears, chilling their very marrows. Then, long after, they would hear it, now faint, now loud, going along the sands into the distant darkness. One or more corpses were usually washed ashore soon after. In the villages the Cyhyraeth is heard passing through the empty streets and lanes by night, groaning dismally, sometimes rattling the window-shutters, or flinging open the door as it flits by. When going along the country lanes it will thus horrify the inmates of every house it passes. Some old people say it is only heard before the death of such as are of strayed mind, or who have long been ill; but it always comes when an epidemic is about to visit the neighbourhood.
