About two miles from Peel, opposite to the Tynwald Mount, lies a hill called Sliue Whallan, which is said to be haunted by the spirit of a murdered witch. She does not appear to mortal eyes, but every night joins her lamentations to the howling winds. She is said to have been put into a barrel with sharp iron spikes inserted round the interior, pointing inwards, and rolled from the top of the hill to the bottom.
