The face of the professor showed clear for a moment. Like McGuire he was bleeding, and his breath came in short explosive gasps, but he was holding his own! The eyes of McGuire glimpsed a wildly gesticulating, shouting figure in the rear. The face, contorted with rage, was almost the color of the brilliant scarlet that the creature wore. The blood-stained man in khaki left his companion to fight his own battle, and plunged headlong at a leaping cluster of dull red, smashed through with a frenzied attack of straight rights and lefts, and freed himself to make one final leap at the leader of this unholy pack. He was fighting in blind desperation now; the two were out-numbered by the writhing, lean-bodied creatures, and this thing that showed in blurred crimson before him was the directing power of them all. The figure symbolized and personified to the raging man all the repulsive ugliness of the leaping horde. The face came clear before him through the mist of blood, and he put the last ounce of his remaining strength and every pound of weight behind a straight, clean drive with his right fist. His last conscious impression was of a red, clawing hand that was closed around the thick butt of a tube of steel ... then down, and still down, he plunged into a bottomless pit of whirling, red flashes and choking fumes.... There were memories that were to occur to Lieutenant McGuire afterward--visions, dim and hazy and blurred, of half-waking moments when strange creatures forced food and water into his mouth, then held a mask upon his face while he resisted weakly the breathing of sweet, sickly fumes that sent him back to unconsciousness. There were many such times; some when he came sufficiently awake to know that Sykes was lying near him, receiving similar care. Their lives were being preserved: How, or why, or what life might hold in store he neither knew nor cared; the mask and the deep-drawn fumes brought stupor and numbness to his brain. A window was in the floor beside him when he awoke--a circular window of thick glass or quartz. But no longer did it frame a picture of a sky in velvet blackness; no unwinking pin-points of distant stars pricked keenly through the night; but, clear and dazzling, came a blessed radiance that could mean only sunshine. A glowing light that was dazzling to his sleep-filled eyes, it streamed in golden--beautiful--to light the unfamiliar room and show motionless upon the floor the figure of Professor Sykes. His torn clothing had been neatly arranged, and his face showed livid lines of healing cuts and bruises. McGuire tried gingerly to move his arms and legs; they were still functioning though stiff and weak from disuse. He raised himself slowly and stood swaying on his feet, then made his uncertain way to his companion and shook him weakly by the shoulder.
