When trees beside wells had rags hung on them as offerings, they would naturally be reverenced, as the living altars for the reception of the gifts. But even when not used for this purpose, they were sometimes thought to have a mysterious connection with the springs they overshadowed. In the parish of Monzie, Perthshire, is a mineral well held in much esteem till about the year 1770. At that time two trees, till then the guardians of the spring, fell, and with their fall its virtue departed. On the right bank of the Clyde, about three-quarters of a mile from Carmyle village, is the once sylvan district of Kenmuir. There, at the foot of a bank, is a spring locally known as "The Marriage Well," the name being derived, it is said, from two curiously united trees beside its margin. These trees were recently cut down. In former times, it was customary for marriage parties, the day after their wedding, to visit the spring, and there pledge the bride and bridegroom in draughts of its sparkling water. On the banks of the Kelvin, close to the Glasgow Botanic Gardens, once flowed a spring styled the Pear-Tree, Pea-Tree, or Three-Tree Well, the last name being probably the original one. In former times it was a recognised trysting-place for lovers. A tragic story is told in connection with it by Mr. James Napier in his "Notes and Reminiscences of Partick." A maiden, named Catherine Clark, arranged to meet her lover there by night, "nor did she ever dream But that he was what he did ever seem." She never returned to her home. "A few days after," remarks Mr. Napier, "her body was found buried near a large tree which stood within a few yards of the Pea-Tree Well. This tree was afterwards known as 'Catherine Clark's Tree,' and remained for many years an object of interest to the visitors to this far-famed well, and many a sympathising lover carved his name in rude letters on its bark. But the tree was also an object of terror to those who had to pass it in dark and lonely nights, and many tales were told of people who had seen a young female form dressed in white, and stained with blood, standing at the tree foot." The tree was removed many years ago. The spring too is gone, the recent extension of the Caledonian Railway to Maryhill having forced it to quit the field.
