A half hour passed, during which there was no sign. The sun was low, and Harry shivered, sitting motionless in the chill of the valley. A snow-bunting came flitting along and lighted fearlessly beside him, and the next moment a great snowy owl swept over the ridge and down upon the snow-bunting, which wriggled between Harry’s feet for protection. The owl glared at him fiercely for a moment with great round eyes, then slipped into the air again, and vanished down the valley. As Harry watched him, he saw branching antlers, and a caribou came around the curve, followed by more and more, feeding and wandering toward him. He sat rigid, his eyes fixed upon them like a dog at the point. They nibbled at the gray moss, unconscious of danger, but lifted their heads and gazed in surprise as a most discordant bellow came from the circle of stone where Harluk lay hidden. Their manner changed in a moment from shambling and slouchy to alert, upheaded, and vigilant. They pawed the earth and sniffed suspiciously, then began to move toward Harluk’s stone fort. Their heads were high, their muzzles thrust forward, and they trod with dainty alertness where before they had shambled. Out of the tail of his eye Harry could see Harluk’s hand and fur-clad arm waving grotesquely above the stones. It was this that had held the attention of the herd and toward which their curiosity was leading them. Within twenty minutes the whole herd were circling about the little inclosure of stone, drawing nearer and nearer to the hand that waved above it. They were within gunshot of either Harry or Joe now, but neither might shoot lest he endanger Harluk. Moreover, neither boy had shot deer before, and the sight of forty of these great creatures within gunshot had given both the buck fever. Harry found himself shaking as with the palsy, and had an almost irresistible desire to throw his gun in the air and halloo.
