"Not yet, old pal. We'll make a fight for it," the Montanan answered.

"I'm sick." The soldier's head sank down. His eyes closed.

All the splendid, lithe strength of his athletic youth had been beaten out of him. To Morse it looked as though he were done for. Was it possible for one to take such a terrific mauling and not succumb? If he were at a hospital, under the care of expert surgeons and nurses, with proper food and attention, he might have a chance in a hundred. But in this Arctic waste, many hundred miles from the nearest doctor, no food but the coarsest to eat, it would be a miracle if he survived.

The bitter night was drawing in. Morse drove West in front of him to bring back the wood he had been cutting. He made the man prepare the rubaboo for their supper. After the convict had eaten, he bound his hands again and let him lie down in his blankets beside the fire.

Morse did not sleep. He sat beside his friend and watched the fever mount in him till he was wildly delirious. Such nursing as was possible he gave.

The prisoner, like a chained wild beast, glowered at him hungrily. Tom knew that if West found a chance to kill, he would strike. No scruple would deter him. The fellow was without conscience, driven by the fear of the fate that drew nearer with every step southward. His safety and the desire of revenge marched together. Beresford was out of the way. It would be his companion's turn next.

After a time the great hulk of a man fell asleep and snored stertorously. But Tom did not sleep. He dared not. He had to keep vigilant guard to save both his friend's life and his own. For though West's hands were tied, it would be the work of only a minute to burn away with a live coal the thongs that bound them.

The night wore away. There was no question of travel. Beresford was in the grip of a raging fever and could not be moved. Morse made West chop wood while he stood over him, rifle in hand. They were short of food and had expected to go hunting next day. The supplies might last at best six or seven more meals. What was to be done then? Morse could not go and leave West where he could get at the man who had put him in prison and with a dog-train to carry him north. Nor could he let West have a rifle with which to go in search of game.

There were other problems that made the situation impossible. Another night was at hand, and again Tom must keep awake to save himself and his friend from the gorilla-man who watched him, gloated over him, waited for the moment to come when he could safely strike. And after that there would be other nights—many of them.

What should he do? What could he do? While he sat beside the delirious officer, Tom pondered that question. On the other side of the fire lay the prisoner. Triumph—a horrible, cruel, menacing triumph—rode in his eye and strutted in his straddling walk when he got up. His hour was coming. It was coming fast.
