I laughed, and he went to his rooms and returned with a large leather-bound book. It was lettered, in the rococo style of a young man's taste, 'Glimpses of the Unknown,' and some of the said glimpses he proceeded to impart to me. It was not pleasant reading; indeed, I had rarely heard anything so well fitted to shatter sensitive nerves. The early part consisted of folk-tales and folk-sayings, some of them wholly obscure, some of them with a glint of meaning, but all of them with some hint of a mystery in the hills. I heard the Brownie story in countless versions. Now the thing was a friendly little man, who wore grey breeches and lived on brose; now he was a twisted being, the sight of which made the ewes miscarry in the lambing-time. But the second part was the stranger, for it was made up of actual tales, most of them with date and place appended. It was a most Bedlamite catalogue of horrors, which, if true, made the wholesome moors a place instinct with tragedy. Some told of children carried away from villages, even from towns, on the verge of the uplands. In almost every case they were girls, and the strange fact was their utter disappearance. Two little girls would be coming home from school, would be seen last by a neighbour just where the road crossed a patch of heath or entered a wood and then--no human eye ever saw them again. Children's cries had startled outlying shepherds in the night, and when they had rushed to the door they could hear nothing but the night wind. The instances of such disappearances were not very common--perhaps once in twenty years--but they were confined to this one tract of country, and came in a sort of fixed progression from the middle of last century, when the record began. But this was only one side of the history. The latter part was all devoted to a chronicle of crimes which had gone unpunished, seeing that no hand had ever been traced. The list was fuller in last century;[1] in the earlier years of the present it had dwindled; then came a revival about the 'Fifties; and now again in our own time it had sunk low. At the little cottage of Auchterbrean, on the roadside in Glen Aller, a labourer's wife had been found pierced to the heart. It was thought to be a case of a woman's jealousy, and her neighbour was accused, convicted, and hanged. The woman, to be sure, denied the charge with her last breath; but circumstantial evidence seemed sufficiently strong against her. Yet some people in the glen believed her guiltless. In particular, the carrier who had found the dead woman declared that the way in which her neighbour received the news was a sufficient proof of innocence; and the doctor who was first summoned professed himself unable to tell with what instrument the wound had been given. But this was all before the days of expert evidence, so the woman had been hanged without scruple. Then there had been another story of peculiar horror,
