Before midday, traveling down a broad stream, past snow-buried willows and naked aspens, and across heavily timbered flats of spruce, they came upon the site of a large camp, recently abandoned. Glancing as he went by, Smoke estimated four or five hundred fires, and guessed the population to be in the thousands. So fresh was the trail, and so well packed by the multitude, that Smoke and his captors took off their snow-shoes and in their moccasins struck a swifter pace. Signs of game appeared and grew plentiful--tracks of wolves and lynxes that without meat could not be. Once, one of the Indians cried out with satisfaction and pointed to a large area of open snow, littered with fang-polished skulls of caribou, trampled and disrupted as if an army had fought upon it. And Smoke knew that a big killing had been made by the hunters since the last snow-flurry. In the long twilight no sign was manifested of making camp. They held steadily on through a deepening gloom that vanished under a sky of light--great, glittering stars half veiled by a greenish vapor of pulsing aurora borealis. His dogs first caught the noises of the camp, pricking their ears and whining in low eagerness. Then it came to the ears of the humans, a murmur, dim with distance, but not invested with the soothing grace that is common to distant murmurs. Instead, it was in a high, wild key, a beat of shrill sound broken by shriller sounds--the long wolf-howling of many wolf-dogs, a screaming of unrest and pain, mournful with hopelessness and rebellion. Smoke swung back the crystal of his watch and by the feel of finger-tips on the naked hands made out eleven o'clock. The men about him quickened. The legs that had lifted through a dozen strenuous hours lifted in a still swifter pace that was half a run and mostly a running jog. Through a dark spruce-flat they burst upon an abrupt glare of light from many fires and upon an abrupt increase of sound. The great camp lay before them. And as they entered and threaded the irregular runways of the hunting-camp, a vast tumult, as in a wave, rose to meet them and rolled on with them--cries, greetings, questions and answers, jests and jests thrust back again, the snapping snarl of wolf-dogs rushing in furry projectiles of wrath upon Smoke's stranger dogs, the scolding of squaws, laughter, the whimpering of children and wailing of infants, the moans of the sick aroused afresh to pain, all the pandemonium of a camp of nerveless, primitive wilderness folk. Striking with clubs and the butts of guns, Smoke's party drove back the attacking dogs, while his own dogs, snapping and snarling, awed by so many enemies, shrank in among the legs of their human protectors, and bristled along stiff-legged in menacing prance.
