Read the excerpt from Part 2 of “To Build a Fire.”He spoke to the dog, calling it to him; but in his voice was a strange note of fear that frightened the animal, who had never known the man to speak in such a way before. Something was the matter, and its suspicious nature sensed danger—it knew not what danger, but somewhere, somehow, in its brain arose an apprehension of the man. It flattened its ears down at the sound of the man's voice, and its restless, hunching movements and liftings and shiftings of its forefeet became more pronounced; but it would not come to the man. He got on his hands and knees and crawled toward the dog. This unusual posture again excited suspicion, and the animal sidled mincingly away.
