He rose from his covert and started again, although he felt that he was growing weaker. Such intense exertion, under such conditions, was bound to tell even upon a frame like his, but he would not let himself falter, passing from island to island, resting a little at every one, bearing toward the southeast, and intending to enter the forest about a mile from the fire on that side. Meanwhile, the chill of the deadly cold and elation over his escape fought for the mastery of him. He reached the last little island, scarcely ten yards from the shore, and as he stepped upon it, two dusky figures threw themselves upon him. Henry was thrown back upon the ice, but though the blow was like a lightning flash, he realized, in an instant, what it meant. The warriors had not been wholly paralyzed by the cold, and they had stationed guards at other points along the lagoon to prevent his escape, but these two were seeking so hard to protect themselves from the cruel wind that they had not seen him until he was upon them. Knowing that the question of his life or death would be decided within the next half minute, he put forth every ounce of his mighty strength, and swept the two warriors together in his arms. His rifle clattered upon the ice, and with the two men clinging to him, struggling vainly to reach tomahawk or knife, he rose to his feet, still clutching the warriors. But the feet of all three slipped from under them, and down they went again with a tremendous impact. The warriors were on the underside, and Henry fell upon them. There was a rending crash, as the ice, thinner at that point, owing to the protection of the island, broke beneath the blow. Henry felt the grappling fingers slip from him, and he sprang back just in time to see the two warriors sink into a narrow but icy gulf, from which they never rose again. Uttering a cry of horror, he picked up his rifle and ran for the forest. He knew that chance, or perhaps the will of the greater powers, had saved him again, but, as he ran, he shuddered many times, not from the cold, but at the ghastly fate that had overtaken the warriors. The impression faded by and by. When one is in a bitter struggle for life he does not have time to think long of the fate of others, and the savage wilderness through which he fled was too bitter of aspect then to breed a long pity. He was quite sure that he had shaken off the Indians, for the time, anyhow, and again the vital question with him was warmth. The running was bringing a measure of it, but he could not run forever, and he soon sank to a walk in order to save himself. But he maintained this gait for a long time, in truth, until dawn was only three or four hours away, and then he decided that he would build a fire. It was a risk, but he chose to take the smaller risk in order to drive off the greater.
