‘A very large cairn west of Luther Water was called Katie’s Cairn because it supposedly marked the spot where Katie the witch was burnt. This is probably the same cairn described as the Witch Knap in Watt’s Highways ans Byways, in which it was placed just east of the burn. Every schoolboy knew to contribute a stone to the when passing-or else the witch would get them. The cairn evaporated during the stone-hungry years of the mid-nineteenth century.‘
