The following, from the Rev. Dr. Gregor's "Folklore of the North-East of Scotland," has certainly nothing to do with a saint, but in other respects, has a bearing on the subject in hand:--"The Pot o' Pittenyoul is a small but romantic rock-pool in a little stream called the 'Burn o' the Riggins,' which flows past the village of Newmills of Keith. On the edge of the pool are some hollows worn away by the water and the small stones and sand carried down by the stream. These hollows to a lively imagination have the shape of a seat, and the story is, that the devil, at some far-back time, sat down on the edge of the pool and left his mark." Probably at an equally distant date, the devil made his presence felt, further south, though in a different way. He had great objections to a church built at Invergowrie, in Perthshire, and, in order to knock it down, hurled a huge boulder across the Tay from the opposite coast of Fife. We are not aware that the stone struck the church. At any rate it can be seen in the grounds of Greystane, a property to which, according to local tradition, it gave name. Sir William Wallace, though never canonized, had certainly more of the saint about him than the last-mentioned personage. We find various traditions concerning him in the Upper Ward of Lanarkshire. His connection with Lanark is well known. At Biggar, he is said, by Blind Harry, to have defeated the English, who greatly outnumbered his forces. This battle took place on Biggar Moss. A few days before the fight, he entered the enemy's camp, disguised as a cadger or pedlar, to discover the strength of the English army. Being pursued, he turned on his assailants while crossing a bridge over Biggar Water, a little to the west of the town. A foot-bridge there still goes by the name of The Cadger's Bridge. A rock with a hollow in it, lying to the north of Vizzyberry, is locally styled Wallace's Seat, and a spring near the spot is still known as Wallace's Well. CHAPTER VI. HEALING AND HOLY WELLS.
