Macphie of Colonsay was kept captive by a mermaid in a cave by the shore. She supplied him with whatever he needed or desired, but he was not happy, and took advantage of her absence to make his escape. She missed him on her return and went in pursuit. He had with him a large black dog, which he had kept in spite of everyone’s remonstrances. When the mermaid overtook him he threw it into the water and it fought the mermaid. The end of the battle was that the dog killed the mermaid and the mermaid killed the dog. This version is the one which supplied the ground work of Leyden’s beautiful ballad “The Mermaid.” Considerable changes must have been made by him upon the legend as it came to his hand. The dog, which in all the versions is the principal character, is left out; Macphie’s name is changed to Macphail; a magic ring (a thing unknown in Highland lore) is introduced, etc. Leyden fell in with the version, of which he made use, in his travels in the Highlands in 1801. Macphie of Colonsay was in an island hunting, and in the course of his ramblings came to a hut, which he entered. He found no one in, and threw himself on a bed for a little rest. He was accompanied by a dog as large as a year old calf. A dark object (_dùthra_) came to the door and the dog attacked it. The Thing made a hideous screaming. When Macphie saw the dog’s hair beginning to smoke, he made his escape to the boat that had come with him to the island. Before long the dog came rushing after him, like a mad beast, with a green flame issuing from its jaws. Macphie had prepared himself for this by loading his double-barrelled gun[41] with two crooked sixpences. He fired the two shots at the dog, as it rushed to attack him, and killed it. The Banshi, it had fought with, was left cruelly mauled, and she crawled or dragged herself to the shore, throwing rocks and stones out of her way. Her track is still known as the Carlin’s Furrow (_Sgrìob na Caillich_). The boat left the shore before she reached it. She tried to bring it back by throwing a ball of thread after it, but without success. This was in Islay.
