much darker blue than he had ever seen on Malacandra. Indeed, it was darker than blue; it was almost black, and the jagged spines of rock standing against it were like his mental picture of a lunar landscape. Some stars were visible.
Suddenly he realized the meaning of these phenomena. There was very little air above him: he was near the end of it. The Malacandrian atmosphere lay chiefly in the handramits; the real surface of the planet was naked or thinly clad. The stabbing sunlight and the black sky above him were that 'heaven' out of which he had dropped into the Malacandrian world, already showing through the last thin veil of air. If the top were more than a hundred feet away, it would be where no man could breathe at all. He wondered whether the hrossa had different lungs and had sent him by a road that meant death for man. But even while he thought of this he took note that those jagged peaks blazing in sunlight against an almost black sky were level with him. He was no longer ascending. The road ran on before him in a kind of shallow ravine bounded on his left by the tops of the highest rock pinnacles and on his right by a smooth ascending swell of stone that ran up to the true harandra. And where he was he could still breathe, though gasping, dizzy and in pain. The blaze in his eyes was worse. The sun was setting. The hrossa must have foreseen this; they could not live, any more than he, on the harandra by night. Still staggering forward, he looked about him for any sign of Augray's tower, whatever Augray might be.
Doubtless he exaggerated the time during which he thus wandered and watched the shadows from the rocks lengthening towards him. It cannot really have been long before he saw a light ahead - a light which showed how dark the surrounding landscape had become. He tried to run but his body would not respond. Stumbling in haste and weakness, he made for the light; thought he had reached it and found that it was far farther off than he had supposed; almost despaired; staggered on again, and came at last to what seemed a cavern mouth. The light within was an unsteady one and a delicious wave of warmth smote on his face. It was firelight. He came into the mouth of the cave and then, unsteadily, round the fire and into the interior, and stood still blinking in the light. When at last he could see, he discerned a smooth chamber of green rock, very lofty. There were two things in it. One of them, dancing on the wall and roof, was the huge, angular shadow of a sorn: the other, crouched beneath it, was the sorn himself.
Chapter XV
"COME IN, Small One," boomed the sorn. "Come in and let me look at you."
Now that he stood face to face with the spectre that had haunted him ever since he set foot on Malacandra, Ransom felt a surprising indifference. He had no idea what might be coming next, but he was determined to carry out his programme; and in the meantime the warmth and more breathable air were a heaven in themselves. He came in, well in past the fire, and answered the sorn. His own voice sounded to him a shrill treble.
"The hrossa have sent me to look for Oyarsa," he said.
The sorn peered at him. "You are not from this world," it said suddenly.
"No," replied Ransom, and sat down. He was too tired to explain.
"I think you are from Thulcandra, Small One," said the sorn.
"Why?" said Ransom.
"You are small and thick and that is how the animals ought to be made in a heavier world. You cannot come from Glundandra, for it is so heavy that if any animals could live there they would be flat like plates - even you, Small One, would break if you stood up on that world. I do not think you are from Perelandra, for it must be very hot; if any came from there they would not live when they arrived here. So I conclude you are from Thulcandra."
"The world I come from is called Earth by those who live there," said Ransom. "And it is much warmer than this. Before I came into your cave I was nearly dead with cold and thin air."
The sorn made a sudden movement with one of
