The petrifying power of certain springs would also tend to bring them into notice. There is a famous well of this kind near Tarras Water, in Canonbie parish, Dumfriesshire. In Kirkmaiden parish, Wigtownshire, is a dropping cave, known as Peter's Paps. In former times it was resorted to by persons suffering from whooping-cough. The treatment consisted in standing with upturned face below the drop, and allowing it to fall into the open mouth. For more than two centuries and a half, the mineral waters of Peterhead have been famous for both internal and external use, though their fame is not now so great as formerly. Towards the end of the seventeenth century, they were spoken of as one of the six wonders of Buchan. The principal well is situated to the south of the town, and is popularly called the Wine Well. Its water is strongly impregnated with carbonic acid, muriate of iron, muriate of lime, and muriate of soda. The chalybeate spring in the Moss of Melshach, in Kennethmont parish, had at one time a considerable local reputation for the cure of man and beast. Clothes of the former and harness of the latter were left beside the well. Visits were paid to it in the month of May. Another Aberdeenshire health-resort formerly attracted many visitors, viz., Pannanich, near Ballater, with its four chalybeate springs. These are said to have been accidentally discovered, about the middle of last century, but were then probably only rediscovered. They were at first found beneficial in the case of scrofula, and were afterwards deemed infallible in all diseases. In his "Antiquities and Scenery of the North of Scotland," Cordiner, under date 1776, writes: "In coming down these hilly regions, stopped the first night at 'Pananach-lodge:' an extensive building opposite to the strange rocks and pass of Bolliter. There, a mineral well and baths, whose virtues have been often experienced, are become much frequented by the infirm. The lodge, containing a number of bed-chambers, and a spacious public room, is fitted up for the accommodation of those who come to take the benefit of the waters. Goat whey is also there obtained in the greatest perfection." Almost a century later, another visitor to the spot, viz., Queen Victoria, thus writes, in her "More Leaves from the Journal of a Life in the Highlands": "I had driven with Beatrice to Pannanich wells, where I had been many years ago. Unfortunately, almost all the trees which covered the hills have been cut down. We got out and tasted the water, which is strongly impregnated with iron, and looked at the bath and at the humble, but very clean, accommodation in the curious little old inn, which used to be very much frequented." The Well of Spa, at Aberdeen, was more famous in former times than it is now. There are two springs, both of them chalybeate. The amount of iron in the water, however, diminished very considerably more than fifty years ago--a change due to certain digging operations in the neighbourhood.
