Ross pulled his hands under him. Though there was no feeling in them, they obeyed his will clumsily. He levered himself up and looked around. He lay in a narrow crevicelike cut, partly walled in by earth so frozen as to resemble steel. Crusted over it in long streaks from above were tongues of ice. To remain here was to serve his captors' purpose. Ross inched his way to his feet. This opening, which was intended as his grave, was not so deep as the men had thought it in their hurry to be rid of him. He believed that he could climb out if he could make his body answer to his determination. Somehow Ross made that supreme effort and came again to the rutted path from which they had tumbled him. Even if he could, there was no sense in going along that rutted trail, for it led back to the ice-encased building from which he had been brought. They had thrust him out to die; they would not take him in. But a road so well marked must have some goal, and in hopes that he might find shelter at the other end, Ross turned to the left. The trace continued down the slope. Now the towering walls of ice and snow were broken by rocky teeth as if they had bitten deep upon this land, only to be gnawed in return. Rounding one of those rock fangs, Ross looked at a stretch of level ground. Snow lay here, but the beaten-down trail led straight through it to the rounded side of a huge globe half buried in the ground, a globe of dark material which could only be man-made. Ross was past caution. He must get to warmth and shelter or he was done for, and he knew it. Wavering and weaving, he went on, his attention fixed on the door ahead--a closed oval door. With a sob of exhausted effort, Ross threw himself against it. The barrier gave, letting him fall forward into a queer glimmering radiance of bluish light. The light rousing him because it promised more, he crawled on past another door which was flattened back against the inner wall. It was like making one's way down a tube. Ross paused, pressing his lifeless hands against his bare chest under the edge of his tunic, suddenly realizing that there was warmth here. His breath did not puff out in frosty streamers before him, nor did the air sear his lungs when he ventured to draw in more than shallow gulps. With that realization a measure of animal caution returned to him. To remain where he was, just inside the entrance, was to court disaster. He must find a hiding place before he collapsed, for he sensed he was very near the end of his ability to struggle. Hope had given him a flash of false strength, the impetus to move, and he must make the most of that gift. His path ended at a wide ladder, coiling in slow curves into gloom below and shadows above. He sensed that he was in a building of some size. He was afraid to go down, for even looking in that direction almost finished his sense of balance, so he climbed up.
