confession, and with his dying breath averred, and truly, as he thought, the truth of the vision on Salisbury Plain. Similar stories might be produced, showing plainly that, under the direction of Heaven, the influence of superstitious fear may be the appointed means of bringing the criminal to repentance for his own sake, and to punishment for the advantage of society. Cases of this kind are numerous and easily imagined, so I shall dwell on them no further; but rather advert to at least an equally abundant class of ghost stories, in which the apparition is pleased not to torment the actual murderer, but proceeds in a very circuitous manner, acquainting some stranger or ignorant old woman with the particulars of his fate, who, though perhaps unacquainted with all the parties, is directed by a phantom to lay the facts before a magistrate. In this respect we must certainly allow that ghosts have, as we are informed by the facetious Captain Grose, forms and customs peculiar to themselves. There would be no edification and little amusement in treating of clumsy deceptions of this kind, where the grossness of the imposture detects itself. But occasionally cases occur like the following, with respect to which it is more difficult, to use James Boswell's phrase, "to know what to think." Upon the 10th of June, 1754, Duncan Terig, _alias_ Clark, and Alexander Bain MacDonald, two Highlanders, were tried before the Court of Justiciary, Edinburgh, for the murder of Arthur Davis, sergeant in Guise's regiment, on the 28th September, 1749. The accident happened not long after the civil war, the embers of which were still reeking, so there existed too many reasons on account of which an English soldier, straggling far from assistance, might be privately cut off by the inhabitants of these wilds. It appears that Sergeant Davis was missing for years, without any certainty as to his fate. At length, an account of the murder appeared from the evidence of one Alexander MacPherson (a Highlander, speaking no language but Gaelic, and sworn by an interpreter), who gave the following extraordinary account of his cause of knowledge:--He was, he said, in bed in his cottage, when an apparition came to his bedside and commanded him to rise and follow him out of doors. Believing his visitor to be one Farquharson, a neighbour and friend, the witness did as he was bid; and when they were without the cottage, the appearance told the witness he was the ghost of Sergeant Davis, and requested him to go and bury his mortal remains, which lay concealed in a place he pointed out in a moorland tract called the Hill of Christie. He desired him to take Farquharson with him as an assistant. Next day the witness went to the place specified, and there found the bones of a human body much decayed. The witness did not at that time bury the bones so found, in consequence of which negligence the sergeant's ghost again appeared to him, upbraiding him with his breach of promise.
