But Kane was too puzzled to be altogether relieved. It was not according to the books for any wolf, great or small, to conduct himself in this supercilious fashion. Looking back along the white bed of the brook, the path by which he must return, he saw that the sinking of the moon would very soon involve it in thick shadow. This was not as he wished it. He had had enough of fishing. Gathering up his now frozen prizes, and strapping the bag that contained them over his shoulder, so as to leave both hands free, he set out for home at the long, deliberate, yet rapid lope of the experienced snowshoer; and the yellow dog, confidence in his companion's prowess now thoroughly established, trotted on heedlessly three or four paces ahead. Already the shadow of the woods lay halfway across the bed of the brook, but down the middle of the strip of brightness, still some five or six paces in breadth, Kane swung steadily. As he went, he kept a sharp eye on the shadowed edge of his path. He had gone perhaps a mile, when all at once he felt a tingling at the roots of his hair, which seemed to tell him he was being watched from the darkness. Peer as he would, however, he could catch no hint of moving forms; strain his ears as he might, he could hear no whisper of following feet. Moreover, he trusted to the keener senses, keener instincts, of the dog, to give him warning of any furtive approach; and the dog was obviously at ease. He was just beginning to execrate himself for letting his nerves get too much on edge, when suddenly out from the black branches just ahead shot a long, spectral shape and fell upon the dog. There was one choked yelp--and the dog and the terrible shape vanished together, back into the blackness. It was all so instantaneous that before Kane could get his rifle up they were gone. Startled and furious, he fired at random, three times, into cover. Then he steadied himself, remembering that the number of cartridges in his chamber was not unlimited. Seeing to it that his axe and knife were both loose for instant action, he stopped and replenished his Winchester. Then he hurried on as fast as he could without betraying haste.
