That night, in addition to the skins across the doorway, Koot jammed logs athwart; "to keep the cold out" he told himself. Then he kindled a fire on the rough stone hearth built at one end of the cabin and with the little clay pipe beneath his teeth sat down on the stump chair to broil rabbit. The waste of the rabbit he had placed in traps outside the lodge. Once his dog sprang alert with pricked ears. Man and dog heard the sniff--sniff--sniff of some creature attracted to the cabin by the smell of broiling meat, and now rummaging at its own risk among the traps. And once when Koot was stretched out on a bear-skin before the fire puffing at his pipe-stem, drying his moccasins and listening to the fusillade of frost rending ice and earth, a long low piercing wail rose and fell and died away. Instantly from the forest of the swamp came the answering scream--a lifting tumbling eldritch shriek. "I should have set two traps," says Koot. "They are out in pairs." * * * * * Black is the flag of danger to the rabbit world. The antlered shadows of the naked poplar or the tossing arms of the restless pines, the rabbit knows to be harmless shadows unless their dapple of sun and shade conceals a brindled cat. But a shadow that walks and runs means to the rabbit a foe; so the wary trapper prefers to visit his snares at the hour of the short shadow. It did not surprise the trapper after he had heard the lifting wail from the swamp woods the night before that the bacon in the trap lay untouched. The still hunter that had crawled through the underbrush lured by the dead rabbits over Koot's shoulder wanted rabbit, not bacon. But at the nearest rabbit snare, where a poor dead prisoner had been torn from the twine, were queer padded prints in the snow, not of the rabbit's making. Koot stood looking at the tell-tale mark. The dog's ears were all aprick. So was Koot's sense of _feel_, but he couldn't make this thing out. There was no trail of approach or retreat. The padded print of the thief was in the snow as if the animal had dropped from the sky and gone back to the sky. Koot measured off ten strides from the rifled snare and made a complete circuit round it. The rabbit runway cut athwart the snow circle, but no mark like that shuffling padded print. "It isn't a wolverine, and it isn't a fisher, and it isn't a coyote," Koot told himself.
