Cold winter lay deep in the Canadian wilderness. Over it the moon was rising, like a red pulsating ball, lighting up the vast white silence of the night in a shimmering glow. Not a sound broke the stillness of the desolation. It was too late for the life of day, too early for the nocturnal roamings and voices of the creatures of the night. Like the basin of a great amphitheater the frozen lake lay revealed in the light of the moon and a billion stars. Beyond it rose the spruce forest, black and forbidding. Along its nearer edges stood hushed walls of tamarack, bowed in the smothering clutch of snow and ice, shut in by impenetrable gloom. A huge white owl flitted out of this rim of blackness, then back again, and its first quavering hoot came softly, as though the mystic hour of silence had not yet passed for the night-folk. The snow of the day had ceased, hardly a breath of air stirred the ice-coated twigs of the trees. Yet it was bitter cold - so cold that a man, remaining motionless, would have frozen to death within an hour.
