Time passed, and the red ring of fire about Paul and Henry sank. Hasty and tired, they had not drawn up enough wood to last out the night, and now the flames died, one by one. Then the coals smoldered and after a while they too began to go out, one by one. The red ring of fire that inclosed the two boys was slowly going away. It broke into links, and then the links went out. Light clouds came up from the west, and were drawn, like a veil, across the sky. The moon began to fade, the silver armor melted away from the trees, and the wild cat that had come back could scarcely see the two strange beings, keen though his eyes were, so dense was the shadow where they lay. The wild things, still devoured with curiosity, pressed nearer. The terrible red light that filled their souls with dread, was gone, and the forest had lost half its terror. There was a ring of eyes about Henry and Paul, but they yet abode in glorious slumberland, peaceful and happy. Suddenly a new note came into the sounds of the wilderness, one that made the timid creatures tremble again with dread. It was faint and very far, more like a quaver brought down upon the wind, but the ring of eyes drew back into the forest, and then, when the quaver came a second time, the rabbits and the deer fled, not to return. The lips of the wild cat contracted into a snarl, but his courage was only of the moment, he scampered away and he did not stop until he had gone a full mile. Then he swiftly climbed the tallest tree that he could find, and hid in its top. The ring of eyes was gone, as the ring of fire had died, but Henry and Paul slept on, although there was full need for them to be awake. The long, distant quaver, like a whine, but with something singularly ferocious in its note came again on the wind, and, far away, a score of forms, phantom and dusky, in the shadow were running fast, with low, slim bodies, and outstretched nostrils that had in them a grateful odor of food, soon to come. Nature had given to Henry Ware a physical mechanism of great strength, but as delicate as that of a watch. Any jar to the wheels and springs was registered at once by the minute hand of his brain. He stirred in his sleep and moved one hand in a troubled way. He was not yet awake, but the minute hand was quivering, and through all his wonderfully sensitive organism ran the note of alarm. He stirred again and then abruptly sat up, his eyes wide open, and his whole frame tense with a new and terrible sensation. He saw the dead coals, where the fire had been; the long, quavering and ferocious whine came to his ears, and, in an instant, he understood. It was well for the two that Henry was by nature a creature of the forest! He sprang to his feet and with one sweeping motion pulled Paul to his also. "Up! Up, Paul!" he cried. "The fire is out, and the wolves are coming!"
