"Do we have to stay? He did not say so, quite."
I considered it. "If you want to go back to the car I'll take you back."
"Well . . . no, Sam, I guess we have to stay. Come closer to me." She was trembling.
I don't know how long it was before they stuck their heads over the rim. The youngster climbed out and the Old Man told him to stand guard. "Come on," he said to us, "it's safe-I think."
"The hell it is," I told him, but I went because Mary was already starting. The Old Man helped her down.
"Mind your head," he said. "Low bridge all the way."
It is a platitude that unhuman races produce unhuman works, but very few humans have ever been inside a Venerian labyrinth and still fewer have seen the Martian ruins-and I was not one of the few. I don't know what I expected. Superficially the inside of the saucer was not, I suppose, too startling, but it was strange. It had been thought out by unhuman brains, ones which did not depend on human ideas in fabricating, brains which had never heard of the right angle and the straight line or which regarded them as unnecessary or undesirable. We found ourselves in a very small oblate chamber and from there we crawled through a tube about four feet thick, a tube which seemed to wind down into the ship and which glowed from all its surface with a reddish light.
The tube held an odd and somewhat distressing odor, as if of marsh gas, and mixed with it faintly was the reek of dead slugs. That and the reddish glow and the total lack of heat response from the wall of the tube as my palms pressed against it gave me the unpleasant fancy that I was crawling through the gut of some unearthly behemoth rather than exploring a strange machine.
The tube branched like an artery and there we came across our first Titanian androgyne. He-let me call it "he"-was sprawled on his back, like a child sleeping, his head pillowed on his slug. There was a suggestion of a smile on the little rosebud mouth; at first I did not realize that he was dead.
At first sight the similarities between the Titanian people and ourselves are more noticeable than the differences; we impress what we expect to see on what we do see, as a wind-sculptured rock may look like a human head or a dancing bear. Take the pretty little "mouth" for example; how was I to know that it was an organ for breathing solely?
Conceded that they are not human and that, despite the casual similarities of four limbs and a head-like protuberance, we are less like them than is a bullfrog like a bullpup; nevertheless the general effect is pleasing, not frightening, and faintly human. "Elfin" I should say-the elves of Saturn's moons. Had we met them before the slugs we call titans possessed them I think we could have gotten along with them. Judged by their ability to build the saucers they were our equals-if they did build them. (Certainly the slugs did not build them; slugs are not builders but thieves, cosmic cuckoos.)
But I am letting my own later thoughts get in the way. When I saw the little fellow I managed to draw my gun. The Old Man, anticipating my reaction, turned and said, "Take it easy. It's dead-they are all dead, smothered in oxygen when the tank ruined their air seal."
I still had my gun out. "I want to burn the slug," I insisted. "It may still be alive." It was not covered by the horny shell we had lately come to expect but was naked, moist and ugly.
He shrugged. "Suit yourself. It can't possibly hurt you."
"Why not?"
"Wrong chemistry. That slug can't live on an oxygen breather." He crawled across the little body, giving me no chance to shoot had I decided to. Mary, always so quick with a gun, had not drawn but had shrunk against my side and was breathing in sharp little sobbing gasps. The Old Man stopped and said patiently, "Coming, Mary?"
She choked and then gasped, "Let's go back! Let's get out of here!"
I said, "She's right. This is no job for three people; this is something for a research team and proper equipment."
He paid no attention to me. "It has to be done, Mary. You know that. And you have to be the one to do it."
"Why does she have to do it?" I demanded angrily.
Again he ignored me. "Well, Mary?"
From somewhere inside herself she called on reserves. Her breathing became normal, her features relaxed, and she crawled across the slug-ridden elfin body with the serenity of a queen going to the gallows. I lumbered after them, still hampered by my gun and trying not to touch the body.
We came at last to a large chamber. It may have been the control room, for there were many of the dead little elfin creatures in it, though I saw nothing resembling (to my eye) instruments or machinery. Its inner surface was cavitated and picked out with lights much brighter than the reddish illumination and the chamber space was festooned with processes as meaningless to me as the convolutions of a brain. I was troubled again with the thought-completely wrong, I know now-that the ship itself was a living organism.
The Old Man paid no attention but crawled on through and into another ruddy-glowing tube. We followed its contortions to a place where it widened out to ten feet or more with a "ceiling" overhead almost tall enough to let us stand erect. But that was not what caught our eyes; the walls were no longer opaque.
On each side of us, beyond transparent membranes, were thousands on thousands of slugs, swimming, floating, writhing in some fluid which sustained them. Each tank had an inner diffuse light of its own and I could see back into the palpitating mass-and I wanted to scream.
I still had my gun out. The Old Man reached back and placed his hand over the bell of it. "Don't yield to temptation," he warned me. "You don't want to let that loose in here. Those are for us."
Mary looked at them with a face too calm. Thinking back, I doubt that she was fully conscious in the ordinary sense. I looked at her, glanced back at the walls of that ghoulish aquarium, and said urgently, "Let's get out of here if we can-then just bomb it out of existence."
"No," he said quietly, "there is more. Come." The tube narrowed in again, then enlarged and we were again in a somewhat smaller chamber like that of the slugs. Again there were transparent walls and again there were things floating beyond them.
I had to look twice before I could fully make out and believe what I saw.
Floating just beyond the wall, face down, was the body of a man-a human. Earth-born man-about forty to fifty years old. He was grizzled and almost bald. His arms were curved across his chest and his knees were drawn up, as if he were sleeping safe in bed-or in the womb.
I watched him, thinking terrible thoughts. He was not alone; there were more beyond him, male and female, young and old-but he was the only one I could see properly and he got my attention. I was sure that he was dead; it did not occur to me to think otherwise-then I saw his mouth working-and then I wished he were dead.
Mary was wandering around in that chamber as if she were drunk-no, not drunk but preoccupied and dazed. She went from one transparent wall to the other, peering intently into the crowded, half-seen depths. The Old Man looked only at her. "Well, Mary?" he said softly.
"I can't find them!" she said piteously in a voice like a little girl's. She ran back to the other side.
The Old Man grasped her arm and stopped her. "You're not looking for them in the right place," he said firmly. "Go back where they are. Remember?"
She stopped and her voice was a wail. "I can't remember!"
"You must remember . . . now. This is what you can do for them. You must return to where they are and look for them."
Her eyes closed and tears started leaking from them. She gasped and choked. I pushed myself between them and said, "Stop this! What are you doing to her?"
