noon
On the fourth night McGill pitched his tent in a clump of _ banskian _ pine a hundred yards back from the water . All that day the wind had come steadily from behind them , and for at least a half of the day the professor had been watching Kazan closely . From the west there had now and then come a scent that stirred him uneasily . Since noon he had sniffed that wind . Twice McGill had heard him growling deep in his throat , and once , when the scent had come stronger than usual , he had bared his fangs , and the bristles stood up along his spine . For an hour after striking camp the little professor did not build a fire , but sat looking up the shore of the lake through his hunting glass . It was dusk when he returned to where he had put up his tent and chained the dogs .
