La-ha-hoo! la-ha-hoo! Far down the widening valley, and up the wild, picturesque ravine, rang the strange but not unmusical call. It awoke the slumbering echoes of the still place, and a hundred voices seemed to take up the cry, and pass it on as from mouth to mouth. But the boy’s quick ears were not to be deceived by the mocking voices of the spirits of solitude, and presently the call rang out again with greater clearness than before: La-ha-hoo! The boy stood with his head thrown back, his fair curls floating in the mountain breeze, his blue eyes, clear and bright and keen as those of a wild eaglet, fixed upon a craggy ridge on the opposite side of the gorge, whilst his left hand was placed upon the collar of a huge wolfhound who stood beside him, sniffing the wind and showing by every tremulous movement his longing to be off and away, were it not for the detaining hand of his young master.
