Five men meeting his neighbour outside the lighthouse stopped him and informed him that having left their boat on the beach, when they went back to it they found it had a hole, and they wished to see in the looking-glass who had done the mischief. When the lighthouse-keeper assured them that he had no such looking-glass, and expressed astonishment that they would believe in such nonsense, they seemed somewhat displeased. In recounting this incident afterwards the light-keepers learned that an impression had gone abroad in the place that there was a particular mirror at the station that had the property of showing who those were that had taken part in cases of witchcraft. It is easily comprehensible how the reflectors in a lighthouse might be spoken of as of peculiar efficacy, with the usual “Three Crows” result. The difficulty of course is to distinguish between claims advanced of the possession of a power, of which, under the circumstances, a demonstration cannot be demanded, and the actual carrying out of some impressive hanky-panky. The following is an illustration:— A messenger being sent for a cure, and having received it, the scientist told him that if the cow had been his own she could make the shadow (_faileas_) of the one who had done the mischief to pass before him, or, if the woman who was the owner of the cow had come, she could have done it for her. One can scarcely be accused of a want of Christian charity if he suggests that if the professor had had the owner before him he would not have claimed the powers he did. In the story already related of Campbell of Skipness showing the injurious one in a carefully darkened barn, the reciter, also a Campbell, had all the appearance of believing in the story, but as it was told of a relative of his great-grandfather’s, no one can say what are the accretions time has added to the facts of the case.
