"Our best chance is to kill a caribou, and this is the kind of country they generally haunt. The sooner we look for one, the better; so I may as well start at once. There'll be a moon to-night."

He threw off his blanket and, picking up a Marlin rifle, which was their only weapon, strode out of camp; and as he was a good shot and tracker they let him go. It was getting dark when he left the shelter of the trees, and the cold in the open struck through him like a knife. The moon had not yet risen and the waste stretched away before him, its whiteness changed to a soft blue-gray. In the distance scattered bluffs rose in long dark smears; but there was nothing to indicate which way Blake should turn, and he had no reason to believe there was a caribou near the camp. As a matter of fact, they had found the larger deer remarkably scarce.

Blake was tired, after breaking the trail since sunrise, and the snow was loose beneath his big net shoes, but he plodded toward the farthest bluff, feeling that he was largely to blame for the party's difficulties. Knowing something of the country, he should have insisted on turning back when he found they could obtain no dog teams to transport their supplies. Occasionally Hudson Bay agents and patrols of the North-West Police made long journeys in arctic weather; but they were provided with proper sleds and sufficient preserved food. Indeed, Blake was astonished that he and his comrades had got so far. He had given way to Harding, who hardly knew the risks he ran, and now he supposed that he must take the consequences. This did not daunt him badly. After all, life had not much to offer an outcast; he had managed to extract some amusement from it, but he had nothing to look forward to. There was no prospect of his making money—his talents were not commercial—and the hardships he could bear now would press on him more heavily as he grew older.

These considerations, however, were too philosophical for him to dwell on. He was essentially a man of action, and was feeling unpleasantly hungry, and he quickened his pace, knowing that the chance of his getting a shot at a caribou in the open was small.

The moon had not risen when he reached the bluff, but the snow reflected a faint light and he noticed a row of small depressions on its surface. Kneeling down, he examined them, but there had been wind during the day and the marks were blurred. He felt for a match, but his fingers were too numbed to open the watertight case, and he proceeded to measure the distance between the footprints. This was an unreliable test, as a big deer's stride varies with its pace, but he thought the tracks indicated a caribou. Then he stopped, without rising, and looked about.

Near in front the trees rose in a shadowy wall against the clear blue sky; there was no wind, and it was oppressively still; the darkness of the woods was impenetrable and its silence daunting. The row of tracks was the only sign of life Blake had seen for days.

While he listened, a faint howl came out of the distance, and was followed by another. After the deep silence, the sound was startling. Blake recognized the cry of the timber wolves, and knew his danger. The big gray brutes would make short work of a lonely man. His flesh crept as he wondered whether, they were on his trail. On the whole, it did not seem likely, though they might get scent of him. Rising to his feet, he felt that the rifle magazine was full before he set off at his highest speed.

The snow was loose, however, and his shoes packed and sank; his breath got shorter, and he began to feel distressed. There was no sound behind him; but that somehow increased his uneasiness, and now and then he anxiously turned his head. Nothing moved on the sweep of blue-gray shadow; and he pressed on, knowing how poor his speed was compared with that the wolves were capable of making. At last, with keen satisfaction, he saw a flicker of light break out from the dark mass of a bluff ahead, and a few minutes later he came, breathing hard, into camp.

"You haven't stayed out long," Benson observed. "I suppose you saw nothing?"

"I heard wolves," Blake answered dryly. "You had better gather wood enough to keep a big fire going, because I've no doubt they'll pick up my trail. However, it's a promising sign."
