Then they vanished without warning, those prints, and I stood hesitant, staring around. I could see nothing, but a brighter glow in the misty canopy overhead marked the sun's position.
I knelt and brushed away the snow with my hands, hoping to undo the wind's concealing work. But I found no more footprints. Finally I took my bearings as well as I could and ploughed ahead in the general direction the girl had been traveling.
My compass told me I was heading due north.
The fog was a living, sentient thing now, secretive, shrouding the secret that lay beyond its gray wall.
Suddenly I was conscious of a change. An electric tingle coursed through my body. Abruptly the fog-wall brightened. Dimly, as through a translucent pane, I could make out vague images ahead of me.
I began to move toward the images—and suddenly the fog was gone!
Before me lay a valley. Blue-white moss carpeted it except where reddish boulders broke the blueness. Here and there were trees—at least I assumed they were trees, despite their unfamiliar outline. They were like banyans, having dozens of trunks narrow as bamboo. Blue-leafed, they stood like immense bird-cages on the pallid moss. The fog closed in behind the valley and above it. It was like being in a huge sun-lit cavern.
I turned my head, saw a gray wall behind me. Beneath my feet the snow was melting and running in tiny, trickling rivulets among the moss. The air was warm and stimulating as wine.
A strange and abrupt change. Impossibly strange! I walked toward one of the trees, stopped at a reddish boulder to examine it. And surprise caught at my throat. It was an artifact—a crumbling ruin, the remnant of an ancient structure whose original appearance I could not fathom. The stone seemed iron-hard. There were traces of inscription on it, but eroded to illegibility. And I never did learn the history of those enigmatic ruins.... They did not originate on Earth.
There was no sign of the native girl, and the resilient moss retained no tracks. I stood there, staring around, wondering what to do now. I was tense with excitement. But there was little to see. Just that valley covering perhaps a half-mile before the fog closed in around it.
Beyond that—I did not know what lay beyond that.
I went on, into the valley, eyeing my surroundings curiously in the shadowless light that filtered through the shifting roof of fog. Foolishly, I expected to discover Incan artifacts. The crumbled red stones should have warned me. They were, I think, harder than metal, yet they had been here long enough for the elements to erode them into featureless shards. Had they been of earthly origin they would have antedated Mankind—antedated even the Neanderthaler man.
Curious how our minds are conditioned to run in anthropomorphic lines. I was, though I did not know it, walking through a land that had its beginnings outside the known universe. The blue trees hinted at that. The crimson ruins told me that clearly. The atmospheric conditions—the fog, the warmth high up in the Cordilleras— were certainly not natural. Yet I thought the explanation lay in some geological warp, volcanic activity, subterranean gas-vents....
My vision reached a half-mile, no farther. As I went on, the misty horizon receded. The valley was larger than I had imagined. It was like Elysium, where the shades of dead men stroll in the Garden of Proserpine. Streamlets ran through the blue moss at intervals, chill as death from the snowy plains hidden in the fog. 'A sleepy world of streams....'
The ruins altered in appearance as I went on. The red blocks were still present, but there were now also remnants of other structures, made by a different culture, I thought.
The blue trees grew more numerous. Leafy vines covered most of them now, saffron-tinted, making each strange tree a little room, screened by the lattice of the vines. As I passed close to one a faint clicking sounded, incongruously like the tapping of typewriter keys, but muffled. I saw movement and turned, my hand going to the pistol in my belt.
The Thing came out of a tree-hut and halted, watching me. I
It was a sphere of what seemed to be translucent plastic, glowing with shifting rainbow colors. And I sensed sentience—intelligence—in its horribly human attitude of watchful hesitation. Four feet in diameter it was, and featureless save for three ivory elastic tentacles that supported it and a fringe of long, whip-like cilia about its diameter—its waist, I thought.
It looked at me, eyeless and cryptic. The shifting colors crawled over the plastic globe. Then it began to roll forward on the three supporting tentacles with a queer, swift gliding motion. I stepped back, jerking out my gun and leveling it.
'Stop,' I said, my voice shrill. 'Stop!'
It stopped, quite as though it understood my words or the gesture of menace. The cilia fluttered about its spherical body. Bands of lambent color flashed. I could not rid myself of the curious certainty, that it was trying to communicate with me.
Abruptly it came forward again purposefully. I tensed and stepped back, holding the gun aimed. My finger was tightening on the trigger when the Thing stopped.
I backed off, nervously tense, but the creature did not follow. After I had got about fifty yards away it turned back and retreated into the hut-like structure in the banyan tree. After that I watched the trees warily as I passed them, but there were no other visitations of that nature.
Scientists are reluctant to relinquish their so-called logic. As I walked I tried to rationalize the creature, to explain it in the light of current knowledge. That it had been alive was certain. Yet it was not protoplasmic in nature. A plant, developed by mutation? Perhaps. But that theory did not satisfy me for the Thing had possessed intelligence, though of what order I did not know.
But there were the seven native girls, I reminded myself. My job was to find them, and quickly, too.
I did, at last, find them. Six of them, anyway. They were sitting in a row on the blue moss, facing one of the red blocks of stone, their backs toward me. As I mounted a little rise I saw them, motionless as bronze statues, and as rigid.
I went down toward them, tense with excitement, expectancy. Odd that six native girls, sitting in a row, should fill me with such feeling. They were so motionless that I wondered as I approached them, if they were dead....
But they were not. Nor were they—in the true sense of the word—alive.
I gripped one by the bare shoulder, found the flesh surprisingly cold and the girl seemed not to feel my touch. I swung her around to face me, and her black, empty eyes looked off into the far distance. Her lips were tightly compressed, slightly cyanosed. The pupils of her eyes were inordinately dilated, as if she was drugged.
Indian style, she squatted cross-legged, like the others. As I pulled her around, she toppled down on the moss, making no effort to stop herself. For a moment she lay there. Then with slow, puppet-like motions, she returned to her former position and resumed that blank staring into space.
I looked at the others. They were alike in their sleep-like withdrawal. It seemed as if their minds had been sucked out of them, that their very selves were elsewhere. It was a fantastic diagnosis, of course. But the trouble with those girls was nothing a physician could understand. It was psychic in nature, obviously.
I turned to the first one and slapped her cheeks. 'Wake up!' I commanded. 'You must obey me! Waken —'
But she gave no sign of feeling, of seeing. I lit a match, and her eyes focused on the flame. But the size of her pupils did not alter....
A shudder racked me. Then, abruptly I sensed movement behind me. I turned....
Over the blue moss the seventh Indio girl was coming toward us. 'Miranda!' I said. 'Can you hear me?' Fra Rafael had told me her name. Her feet, I saw, were bare and white frost-bite blotches marked them. But she did not seem to feel any pain as she walked.
Then I became aware that this was not a simple Indio girl. Something deep within my soul suddenly shrank back with instinctive revulsion. My skin seemed to crawl with a sort of terror. I began to shake so that it was difficult to draw my gun from its holster.
There was just this young native girl walking slowly toward me, her face quite expressionless, her black eyes fixed on emptiness. Yet she was not like other Indios, not like the six other girls sitting behind me. I can only liken her to a lamp in which a hot flame burned. The others were lamps that were dead, unlit.
The flame in her was not one that had been kindled on this earth, or in this universe, or in this space-time
