April 1931

by Unknown

  The metal flanges were fully four feet apart, and it was not easy to scramble down from one to another; certainly not easy for one who was cold, hungry, thirsty, worn out with a week of exhausting marches, and suffering the torture of frozen feet.

  "You know, this thing was not built by men," Ray observed.

  "Not built by men? What do you mean?"

  "Men would have put the steps closer together. Jim, I'm afraid we are up against something--well--that we aren't used to."

  "If men didn't build this, what did?" I was astounded.

  "Search me! This continent has been cut off from the rest of the world for geologic ages. Such life as has been found here is not common to the rest of the earth. It is not impossible that some form of life, isolated here, has developed intelligence and acquired the power to erect that cone of light--and to burn the wing off a metal airplane."

  My thoughts whirled madly as we clambered down the shaft.

  * * * *

  *It must have taken us an hour to reach the bottom. I did not count the steps, but it must have been at least a thousand feet. The air grew rapidly warmer as we descended. We both took off most of our heavy fur garments, and left them hanging on the rungs.

  I was rather nervous. I felt the nearness of an intelligent, hostile power. I had a great fear that the owners of those steps would use them to find us, and then crush us ruthlessly as they had brought down Meriden's plane.

  The little square of white light below grew larger. Finally I saw Ray swing off and stand on his feet in a flood of white radiance below me. The air was warm, moist, laden with a subtle unfamiliar fragrance that suggested growing things. Then I stood beside Ray.

  We stood on the bare stone floor of a huge cavern. It must have been of volcanic origin. The walls glistened with the sparkling smoothness of volcanic glass. It was a huge space. The black roof was a hundred feet high, or more; the cave was some hundreds of feet wide. And it sloped away from us into dim distance as though leading into huger cavities below.

  The light that shone upon us came from an amazing thing--a fall of liquid fire. From the roof plunged a sheer torrent of white brilliantly luminous fluid, falling a hundred feet into a shimmering pool of moon-flame. Shining opalescent mists swirled about it, and the ceaseless roar of it filled the cave with sound. It seemed that a stream of the phosphorescent stuff ran off down the cave from the pool, to light the lower caverns.

  "Very clever!" said Ray. "They make the stuff up there at the cone and run it in here to see by."

  "This warm air feels mighty good," I remarked, pulling off another garment.

  Ray sniffed the air. "A curious odor. Smells like something growing. Where anything is growing there ought to be something to eat. Let's see what we can find."

  Only black obsidian covered the floor about us. Cautiously we skirted the overflowing pool of white fire, and followed down the stream of it that flowed toward the inner cavern. We had gone but a few hundred yards when suddenly Ray stopped me with a hand on my arm.

  "Lie flat!" he hissed. "Quick!"

  He dived behind a huge mass of fire-born granite. I flung myself down beside him.

  "Something is coming up the trail by the shining river. And it isn't a man! It's between us and the light; we should be able to see it."

  * * * *

  *Soon I heard a curious scraping sound, and a little tinkle of metal. I caught a whiff of a powerful odor--a strange, fishy odor--so strong that it almost knocked me down.

  The thing that made the scraping and the tinkle and the smell came into view. The sight of it sickened me with horror.

  It was far larger than a man; its body was heavy as a horse's, but nearer the ground. In form it suggested a huge crab, though it was not very much like any crustacean I had ever seen. It was mostly red in color, and covered with a huge scarlet shell. It had five pairs of limbs. The two forward pairs had pinchers, seemingly used as hands; it scraped along on the other three pairs. Yard-long antennae, slender and luminously green, wavered above a grotesque head. The many facets of compound eyes stood on the end of foot-long stalks.

  The amazing crab-thing wore a metal harness. Bands of silvery aluminum were fastened about its shell, with little cases of white metal dangling to them. In one of its uplifted claws it carried what seemed to be an aluminum bar, two feet long and an inch thick.

  It scraped lumberingly past, between us and the racing stream of white fire. It passed less than a dozen feet from us. The curious fishy smell of it was overpowering, disgusting.

  Sweat of horror chilled my limbs. The monster emanated power, sinister, malevolent power, power intelligent, alien and hostile to man.

  I trembled with the fear that it would see us, but it scrambled grotesquely on. When it was twenty yards past, Ray picked up a block of black lava that lay beneath his hand and hurled it silently and swiftly. It crashed splinteringly on the rocks far beyond the creature, on the other side of the stream of light.

  In fascination I watched the monster as it paused as if astonished. The glittering compound eyes twisted about on their stalks, and the long shining green tentacles wavered questioningly. Then the knobbed limbs snapped the white metal tube to a level position. A metallic click came from it.

  And a ray of red light, vivid and intense, burst from the tube. It flashed across the river of fire. With a dull, thudding burst it struck the rocks where the stone had fallen. It must have been a ray of concentrated heat. Rocks beneath it flashed into sudden incandescence, splintered and cracked, flowed in molten streams.

  * * * *

  *In a moment the intensely brilliant ruby ray flashed off. The rocks in the circle where it had struck faded to a dull red and then to blackness, still cracking and crumbling.

  To my intense relief, the monstrous crab lumbered on.

  "That," Ray whispered, "is what got Major Meriden's airplane wing."

  When we could hear its scraping progress no longer, we climbed up from behind our boulder and continued cautiously down the cavern, beside the rushing luminous river. In half a mile we came to a bend. Rounding it, we gazed upon a remarkable sight.

  We looked into a huge cavity in the heart of the earth. A vast underground plain lay before us, with the black lava of the roof arching above it. It must have been miles across, though we had no way to measure it, and it stretched down into dim hazy distance. Its level was hundreds of feet below us.

  At our feet the glistening river of fire plunged down again in a magnificent flaming fall. Below, its luminous liquid was spread out in rivers and lakes and canals, over all the vast plain. The channels ran through an amazing jungle. It was a forest of fungus, of mushroom things with great fleshy stalks and spreading circular tops. But they were not the sickly white and yellow of ordinary mushrooms, but were of brilliant colors, bright green, flaming scarlet, gold and purple-blue. Huge brilliant yellow stalks, fringed with crimson and black, lifted mauve tops thirty feet or more. It was a veritable forest of flame-bright fungus.

  In the center of this weirdly forested subterranean plain was a great lake, filled, not with the flaming liquid, but with dark crystal water. And on the bottom of that lake, clearly visible from the elevation upon which we stood, was a city!

  * * * *

  *A city below the water! The buildings were upright cylinders in groups of two or three, of dozens, even of hundreds. For miles, the bottom of the great lake was covered with them. They were all of crystal, azure-blue, brilliant as cylinders turned from immense sapphires. They were vividly visible beneath the transparent water. Not one of them broke the surface.

  Through the clear black water we saw moving hundreds, thousands of the giant crabs. The crawled over the hard, pebbled bottom of the lake, or swam between the crystal cylinders of the city. They were huge as the one we had seen, with red shells, great ominous looking stalked eyes, luminous green tentacular antennae and knobbed claws on forelimbs.

  "Looks as if we've run on something to write home about," Ray muttered in amazeme
nt.

  "A whole city of them! A whole world! No wonder they could build that cone-mountain for a lighting plant!"

  "When they got to knocking down airplanes with that heat-ray," he speculated, "they were probably surprised to find that other animals had developed intelligence."

  "Do you suppose those mushroom things are good to eat?"

  "We can try and see--if the crabs don't get us first with a heat-ray. I'm hungry enough to try anything!"

  Again we cautiously advanced. The river of light fell over a sheer precipice, but we found a metal ladder spiked to the rock, with rungs as inconveniently far apart as those in the shaft. It was five hundred feet, I suppose, to the bottom; it took us many minutes to descend.

  At last we stepped off in a little rocky clearing. The forest of brilliant mushrooms rose about us, great fleshy stalks of gold and graceful fringes of black and scarlet about them, with flattened heads of purple.

  We started eagerly across toward the fungoid forest. I had visions of tearing off great pieces of soft, golden flesh and filling my aching stomach with it.

  We were stopped by a sharp, poignantly eager human cry.

  A human being, a girl, darted from among the mushroom stalks and ran across to us. Sobbing out great incoherent cries, she dropped at Ray's feet, wrapped her arms about his knees and clung to him, while her slender body was wracked with sobbing cries.

  * * * *

  *My first impression was that she was very beautiful--and that impression I was never called upon to revise. About her lithe young body she had the merest scrap of some curious green fabric--ample in the warm air of the great cavern. Luxuriant brown hair fell loose about her white shoulders. She was not quite twenty years old, I supposed; her body was superbly formed, with the graceful curves and the free, smooth movements of a wild thing.

  Ray stood motionless for a moment, thunder-struck as I was, while the sobbing girl clung to his knees. Then the astonishment on his face gave place to pity.

  "Poor kid!" he murmured.

  He bent, took her tenderly by the shoulder, helped her to her feet.

  Her beauty burst upon us like a great light. Smoothly white, her skin was, perfect. Wide blue eyes, now appealing, even piteous, looked from beneath a wealth of golden brown hair. White teeth, straight and even, flashed behind the natural crimson of her lips.

  She stood staring at Ray, in a sort of enchantment of wonder. An eager light of incredible joy flamed in her amazing eyes; red lips were parted in an unconscious smile of joy. She looked like the troubled princess in the fairy tale, when the prince of her dreams appeared in the flesh.

  "God, but you're beautiful!" Ray's words slipped out as if he were hardly conscious of them. He flushed quickly, stepped back a little.

  The girl's lips opened. She voiced a curious cry. It was deep toned, pealing with a wonderful timbre. A happy burst of sound, like a baby makes. But strong, ringing, musically golden. And pathetically eager, pitifully glad, so that it brought tears to my eyes, cynical old man that I am.

  I saw Ray wipe his eyes.

  "Can you talk?" Ray put the question in a clear, deliberate voice, with great kindness ringing in it.

  "Talk?" The chiming, golden voice was slow, uncertain. "Talk? Yes. I talked--with mother. But for long--I have had no need to talk."

  "Where is your mother?" Ray's voice was gentle.

  "She is gone. She was here when I was little." The clear, silvery voice was more certain now. "Once, when I was almost as big as she--she was still. She was cold. She did not move when I called her. The Things took her away. She was dead. She told me that sometime she would be dead."

  * * * *

  *Bright tears came in the wide blue eyes, trickled down over the perfect face. A pathetic catch was in the deliberate, halting voice. I turned away, and Ray put a handkerchief to his face.

  "What is your name? Who are you?" Ray spoke kindly.

  "I am Mildred. Mildred Meriden."

  "Meriden!" Ray turned to me. "I bet this is a daughter of the major and his wife!"

  "Father was the major," the girl said slowly. "He and mother came in a machine that flew, from a far land. The Things burned the machine with the red fire. They came here and the Things kept them. They made mother sing over the water. They killed father. I never saw him."

  "I know," Ray, said gently. "We came from the same land. We saw your father's machine above."

  "You came from outside! And you are going back? Oh, take me with you! Take me!" Piteous pleading was in her voice. "It is so--lonely since the Things took Mother away. Mother told me that sometime men would come, and take me away to see the people and the outside that she told me of. Oh, please take me!"

  "Don't worry! You go along whenever we leave--if we can get out."

  "Oh, I am so glad! You are very good!"

  Impulsively, she threw her arms around Ray's neck. Gently, he disengaged himself, flushing a little. I noticed, however, that he did not seem particularly displeased.

  "But can we get out?"

  "Mother and I tried. We could never get out. The Things watch. They make me come to the water to sing, when the great bell rings."

  "Are these things goods to eat?" I motioned to the brilliant fungal forest. I had begun to fear that Ray would never get to this very important topic.

  Blue eyes regarded me. "Eat? Oh, you are hungry! Come! I have food."

  * * * *

  *Like a child, she grasped Ray's hand, pulled him toward the mushroom jungle. I followed, and we slipped in between the brilliantly golden, fleshy stalks. They rose to the tangle of bright feathery fringes above, huge and substantial as the trunks of trees.

  In a few minutes we came to a wide, shallow canal, metal-walled, through which a slow current of the opalescent, luminous liquid was flowing. We crossed this on a narrow metal foot-bridge, and went on through the brilliant forest.

  Suddenly we emerged into a little clearing, with the black waters of the great lake visible beyond it, across a quarter-mile of rocky beach. In the middle of the open space, rose three straight cylinders of azure crystal, side by side. Each must have been twenty feet in diameter, and forty high. They shone with a clear blue light, like the cylindrical buildings we had seen in the strange city of the crab-creatures below the great lake.

  Mildred Meriden, the strangely beautiful girl who had known no other world than this amazing cavern empire where giant crabs reigned, beckoned us with unconscious queenly grace to enter the arched door in the blue sapphire wall of her remarkable abode of clustered cylinders.

  The crystal of the walls seemed luminous, the lofty cylinders were filled with a liquid, azure radiance. The high round room we entered was strangely furnished. There was a silken couch, a bathing pool of blue crystal filled with sparkling water, a curious chest of drawers made of bright aluminum with a mirror of polished crystal, its top bearing odd combs and other articles. The furnishings must have been done by the giant crabs, under human direction.

  Mildred led us quickly across the room, through an arched opening into another. A round aluminum table stood in the center of the room, with two curious metal chairs beside it. Odd metal cabinets stood about the shining blue walls. The girl made us sit down, and put dishes before us.

  She gave us each a bowl of thick, sweetish soup, darkly red; placed before us a dish piled high with little circular cakes, crisp and brown, which had a tantalizing fragrance; poured for each of us a transparent crystal goblet full of clear amber drink.

  We fell to with enthusiasm and abandon.

  "The Things made this place for father," the girl told us, as she watched us eat, attentively replenishing the red soup in the great blue crystal bowl, or the little cakes, or the fragrant amber drink. "They would give him anything he wanted. But he tried to go away with mother, and they killed him."

  "We must get out of here," Ray declared when at last we had done. "We must get together a lot of food, and enough clothing for all of us. We ought to be able to make it to the ed
ge of the ice-pack. We've got to give these crab-things the slip; we ought to get off before they know we're here--unless they already do."

  Mildred was eagerly attentive: she was so unused to human speech that it took the best of her efforts to understand us, though it seems that her mother had given her quite a wide education. She promised that there would be no difficulty about the food.

  "Mother taught me how to fix food," she said. "She always said that sometime men would come, with weapons of fire and great noise that would tear and kill the Things. I have food ready, in bags--more than we can carry. I have, too, the furs that mother and father wore."

  She ran into another room and returned with a great pile of fur garments, which we examined and found to be in good condition.

  "Now is the time," Ray said. "I'd like to know more about the big crabs, but there'll be a chance for that, later. Mildred is the important thing, now. We must get her out. Then we can tell the world about this place and come back with a bigger expedition."

  "You think we can reach the coast?"

  "I think so. It might be hard on Mildred. But we will have food; we can probably find fuel for the stove in Meriden's plane, if the tanks were well sealed. And Captain Harper should have a relief party landed and sent to meet us. We should have only three or four hundred miles to go alone."

  "Three or four hundred miles, over country like we've been crossing in the last week, with a girl! Ray, we'd never make it!"

  "It's the only chance."

  I said nothing more. I knew that I could stand no such march on my frozen feet, but I resolved to say nothing about it. I would help them as far as I could, and then walk out of camp some night. Men have done just that.

  Mildred brought out sacks of the little cakes, and of a red powder that seemed to be the dried and ground flesh of a crimson mushroom. We made a pack for each of us, as heavy as we could carry.

  * * * *

  *Just before we were ready to start Ray took off my footgear and treated my feet from his medicine kit. I had feared gangrene, but he assured me that there was no danger if they were well cared for. Walking was still exquisitely painful to me as we slipped out through the arched door and into the fungoid forest beyond the three blue cylinders.
