wildly tumbled; huge, fantastic ice and snow formations; strewn pools of water, choked with melting ice. Alan and I had mentioned that weird vision we had had of a living girl, so strangely fashioned in human mold. Was she real—or had our fancy tricked us? Dr. Livingston had blankly stared. From the big, handsome Peter Duroh had come a laugh and a ribald expression of hope that we were right. James Carruthers had merely stared incredulously, with his thin lips smiling and a look in his alert eyes that somehow seemed predatory. But whether we had seen something animal or human, assuredly it had been alive. This atmosphere then, doubtless would be breatheable to us; and the temperature down there, by daylight at least, must be around 40F. Dr. Livingston was checking his instruments. Another hour had passed. "Only five hundred miles of altitude now," he said. "I think we may use a little less repulsion for a time, and then the final retardation must begin." Awesome descent. It took us another eighteen earth-hours while the weird convex surface of little Zura came up at us. I was often in the turret alone. Queerly an ominous sense of disaster was upon me. I could not tell why. Fear that we might not land safely? Surely it was not that. Rather was it as though, here in the little Planeteer which had been our world, something was impending. Somehow I had grown to dislike Pete Duroh and Jim Carruthers. Just little things. That ribald laugh. A way they had seemingly of watching me, whispering together while I was at the spectroscope, checking what evidence I could find of the presence of Xalite on the asteroid's surface. And young Grant, boyish multiple murderer, whom now I had come somehow to like—what was it that he had wanted to tell me? I had tried several times to see him alone to ask him; but obviously he was avoiding me now. Whatever it was, he had repented the impulse. We were all five in the turret during the descent through the Zurian atmosphere. Only fifty thousand feet up now. It was night, with glittering stars above us, and below, that wild, tumbled, fantastic landscape spreading now off to the horizon, bleak and grim in the starlight.... Twenty thousand feet. Sudden daylight had come and then night again. We were moving with Zura now in her swift axial rotation, dropping almost vertically down, slowly now with a constant retardation. I did not mention it, but I realized that we were poised very nearly over
