Every few minutes there would be a flicker of darkness in the ascending column, and something like a large fish would splash into the moat, then go shooting off along one of the radiating tubes. Bowman was not surprised when he recognized the intelligent suckerfish he had seen among the roots of the skyplants, but there were also a few creatures remarkably like dolphins and seals. All seemed to know exactly where they were going, and once, a pair of the dolphinoids, apparently out of pure exuberance, leaped straight out of the moat and back into the sea. At the end of the two- hundred-foot dive, their gleaming bodies entered the water simultaneously with scarcely a splash.
This city seemed to have been designed for common use by creatures of the sea and the land-yet so far, he had seen nothing even remotely resembling a human being. Was it possible that, despite all the arguments of the exobiologists, the hominid shape was actually quite rare in the universe-perhaps even unique?
A few minutes later, he had the answer to that question.
INTO THE NIGHT LAND
The creature standing on the balcony below which the ship was now moving possessed two arms, two legs, a vertical torso supporting an ovoid head, and two eyes; almost all the main ingredients of the human body were there, and in approximately the right places. Yet the total result was completely alien, and for the first time Bowman realized how many variations were possible on the basic human design. The biologists had told him this, but he had never really believed it.
The thing was only about five feet tall, and was very stocky, as if it came from a planet with a high gravity. Two large eyes, protected by bony ridges, were set on almost opposite sides of the head. But there was nothing that could be called a face; he could see no sign of mouth, nostrils, or ears. How did the thing manage to eat and breathe? It appeared to be a living creature; presumably it had some kind of metabolism.
Then Bowman looked more carefully at the two small, dark patches which he had assumed were nipples-and he realized how dangerous it was to jump to conclusions about extra terrestrials. These were the nostrils, sensibly located at the nearest point to the lungs. There was no doubt of it; the two small pits were opening and closing with a slow, regular rhythm.
But where was the mouth? For a moment, still conditioned by his human prejudices, Bowman searched in vain. Then he remembered the lesson of the nostrils, asked himself where a competent efficiency expert would put the mouth, and had his answer.
The creature was wearing a somewhat elaborate dress that covered the body up to about a foot below the neck; it hung by straps from a metal collar, and looked rather comically like a giant kilt, complete with sporran in the region of the navel-not that Bowman now imagined for a moment that the creature had a navel.
That "sporran" was really a kind of movable curtain or screen; and beneath it, Bowman was quite sure, would be the mouth, handily placed at the entrance to the stomach. He decided that he would not care to be invited to dinner by these entities, but he had to admit that their alimentary arrangements were more efficient than his. They would doubtless be revolted by his all-purpose eating-speaking breathing organ, permanently exposed to public view.
He wondered how the creature communicated with its kind; perhaps it did not rely on sound at all. Then he remembered that many animals on earth had no visible organs of sound production or detection, and that the absence of external ears proved nothing.
The creature had been watching him as the ship passed beneath its balcony, and at the moment of closest approach it did something completely human. It reached into one of the pockets of its dress, brought out a small metallic box, and raised it to its eyes. It held it there for a few seconds, then put it away again; and Bowman realized that he had had his photograph taken by a collector of biological curiosities.
The ship was now moving slowly through the outskirts of the city, obviously according to some prearranged plan. Was he being shown to its people, or were they being shown to him? His arrival had certainly attracted little attention; he thought of all the crowds that would have gathered on Earth if an alien spaceship had landed. However, it was obvious that this planet was inhabited- or visited-by intelligent creatures of many races; it was also possible that they were too polite to stare at strangers.
He was wrong on that count, as he soon discovered Skirting the edge of a large, circular courtyard or patio; he noticed his first crowd. It was a sparse one, containing not more than a hundred entities of at least six basic types. Besides the two varieties he had already seen, there were tall, slender creatures of almost human form, but with blank, egglike heads absolutely devoid of features. There were also squat cones, supported on dozens of tiny tubelike legs; and there was one impressive thing like a giant praying mantis.
They were all looking (though how the apparently eyeless eggheads managed this was more than Bowman could imagine) at a large bubble hanging in midair at the center of the patio; and in that bubble was-at last-the image of a perfectly normal human face. For a few seconds he looked at it with all the relief of a lost traveler meeting a fellow countryman in a far land; then, with a jarring psychic shock, he realized how totally disoriented he had become.
The face was his own; he had failed to recognize himself.
The mouth inside the bubble fell slackly; then Bowman pulled himself together. You've been on TV before, he told himself wryly; this is no time to get camera fright. (But where the devil was the camera?) Then the scale of the picture changed, so that he could see the whole interior of the cabin. The invisible eye retreated until it seemed that a scale model of Discovery was floating there before the intent little group of spectators. Bowman wondered how long they had been looking at him, and how much they had already seen.
Then the ship moved on, and he lost sight of his audience, though he remained highly conscious of it. He did not see himself again.
The feeling of confident well-being that had gripped him was beginning to wear off, he had seen too much too swiftly, and was becoming punch-drunk with sensations. One fact that added to the mental strain was something that he had never anticipated; he simply had no words for many of the things he was seeing, and this made it impossible for him to marshal his thoughts and to put his experiences in order. He had to make up labels as he went along, but he knew that they were only temporary, perhaps even misleading. Some of the creatures he had hastily classed as hominid might well be less human than the robots (if they were robots). And on this world, there might no longer be any real distinction between intelligences housed in machines, and those that occupied bodies of flesh and blood.
The passing scenes began to blur in his mind, and on several occasions he blanked out for unknown periods of time. For once he found himself sinking down a huge vertical shaft surrounded by water, and had no idea how he had got here. At first he thought that the water was held back by a cylindrical wall of glass or transparent plastic-but then one of the porpoise creatures came shooting straight through the barrier, into the column of air down which Discovery was slowly falling.
The dolphinoid drifted across the well, keeping level with the ship and obviously inspecting it closely. It reached the other side, merged without resistance into the wall of water, and shot off effortlessly with a flurry of flukes.
Not only the laws of matter but the law of gravity seemed to have been repealed in this strange place. Bowman could see many other tunnels heading off into the distance through the incredibly clear water; some were vertical, some horizontal-and the inhabitants of the city were moving along them both with a total disregard for the conventions of "up" and "down." It was not a question of the weightlessness with which he was familiar in space; judging by the way they were standing, the creatures in these tunnels had normal weight, and appeared completely at ease. Where one tunnel had intersected another in the vertical plane, they would switch nonchalantly through a right angle as the gravity field tilted and a wall became a floor.
It was a very disconcerting sight; but doubtless an escalator would have app
eared just as unsettling to a Neanderthal Man.
The well down which he was sinking was perhaps five hundred feet deep, and ended in one of the underwater patios of this amphibious city. He could see, fading away into the blue distance, lines of open structures which he could only describe as roofless-and largely wall-less- buildings. The creatures he had called suckerfish were swimming in and out of these submarine apartments; most of them were moving under their own power, but a few were operating small torpedolike machines. Bowman had never imagined that he would one day see fish riding scooters; and even when he contemplated this thought, it still didn't seem funny.
The suckerfish were very inquisitive, they gathered around in scores, peering into the ship, and they spiraled up with him when Discovery started to rise again, past that vista of radiating tunnels.
The hole in the water widened as it approached the surface; he seemed to be emerging from a kind of stationary whirlpool in the center of a small lake. There were smaller whirlpools orbiting around it, like planets around the sun, and Bowman wondered if they were part of a mobile, liquid sculpture. He could not imagine what other purpose they fulfilled.
And then he was flying over what must have been a residential area, for beneath him were roads that rolled briskly along like moving belts, between wide-spaced buildings no two of which were of the same design-or even, as he presently realized, built to the same scale. Some would not have looked out of place in a housing estate on Earth, but there were others that resembled small chemical processing plants and were presumably occupied by creatures with peculiar domestic requirements. Some were made for giants; others for beings who could hardly be larger than pygmies. And there was one wide, flat pancake of a building whose roof was not more than two feet from the ground....
As Bowman passed over this suburban area-though, in reality, the whole city was a giant suburb-he caught tantalizing glimpses of the life it housed. It was obvious that, to some of its inhabitants, privacy meant absolutely nothing; their homes were as transparent as goldfish bowls. Once he looked into a room where three iridescent beetles, as large as a man, were standing around a bowl of redly fuming liquid, sipping it through flexible trunks or proboscises. In another, dozens of things like giant grubs were busily weaving a web around a cocoon that must have been ten feet long, and vibrated slightly from time to time.
And he saw more of the intelligent plants, standing in troughs of green mud, and swaying ecstatically as they absorbed the rays from a brightly shining globe. Even as he watched, one of the creatures seemed to explode in a cloud of mist, which resolved itself into tiny white parachutes. As they drifted slowly to the ground, Bowman realized that he had witnessed birth and death, but not as humans knew either.
Now the city, with all its meaningless wonders, its mind-wracking vistas, and its fantastic inhabitants, was falling behind him; he could relax once more with the spectacle of those calm, magnificent peaks, gilded by the faintly aureate glow of the eternal dawn. Discovery was moving past them at a considerable speed, racing along the edge of night.
The sky ahead was changing; there was a mist spreading across the horizon, thickening into a great river of cloud. It seemed to form somewhere out in the darkness, and then to flow toward the line of day. Quite abruptly, it plunged downward, in an immense and silent cataract flanked by two of the mountain towers-a slow-moving Niagara, five miles high and fifty miles across. The illusion of falling water was almost perfect; but this avalanche of mist slid down the sky with a dreamlike lethargy, and merged without a splash into the unruffled sea.
The mountain-towers dropped behind him, and the last light of the sun faded from the sky. (How many millions of years, he wondered, since it had shone upon this land?) But the white rainbow of the rings, and two large crescent moons, provided plenty of cold illumination, he could see clear to the horizon, and it seemed that he was flying over a vast snow field rather than a sea of clouds. He had once orbited across the Antarctic under a full moon, only a hundred miles up; it required little effort to imagine that he was back there, waiting to exchange greetings with Mirny or McMurdo....
He passed one mountain, and that a very strange one. It jutted up above the clouds like a giant iceberg-though no structure of ice could possibly be so tall, or so transparent. He could see far into its interior, which was laced with veins of some dark material; though he could not be certain, it seemed that some of these veins pulsed slowly, giving him the impression that he was looking into a gigantic anatomical model. Or perhaps it was not a model, but the real thing, whatever that might be; but this was a thought on which he did not care to dwell.
Then there was only the level sea of cloud-and, just once, a great glowing patch like the lights of a city hidden by the overcast. Presently it too fell astern, and he was alone under the arches of the rings, and the utterly alien stars.
He had now almost completed one half-circuit of this world, and was nearing the center of the nightside. It was easy to tell this, for the great bite taken out of the rings by the eclipsing shadow of the planet was now exactly overhead; he was as far from the forest of the sky plants as he could travel, while still remaining on this world. If he continued on this course, he would be heading back into the day.
Something was eclipsing the stars-something utterly black, rising swiftly up the sky. For an instant he thought it was a mountain, Lying directly in his path; but no natural substance could soak up light as did this column of Stygian darkness. He caught only the faintest gleam from the mingled rays of the two moons, glancing upon fluted, cylindrical walls like polished ebony; and even as Discovery hurtled into the thing, beyond all possibility of avoidance, a long-forgotten line of poetry surged up from the depths of his memory. He found himself repeating desperately, like an incantation to ward off disaster: "Childe Harold to the Dark Tower came."
Then the Dark Tower was upon him, and his only regret was that he had seen so much and learned so little.
There was no impact and no sound, but the stars and the clouds were gone. Instead, the ship was moving through an infinite lattice of softly glowing lights-a misty, three-dimensional grid which appeared to have neither beginning nor end. For a moment Discovery seemed to coast forward on its own momentum; then it began to fall.
Faster and faster, the arrays of light went flickering by, as Discovery plunged downward at ever-accelerating speed. Without astonishment-for he was now beyond such an emotion-Bowman saw that the nodes of luminescence were passing through the solid walls of the ship as they raced upward; indeed, he could see them streaming through his own body.
Now he was falling through the grid so swiftly that the individual knots of light could no longer be seen; they were merely pulsations in the lines that went flickering vertically past. He must have descended for miles; by this time, surely, he was far below the surface of the planet- if he was moving through real space at all.
Suddenly, the shining lattice was gone; he was falling toward darkness, out of a dully glowing sky. And on that darkness, the ship came at last to rest.
It was a place without horizons, or any sense of scale. A hundred feet or a hundred miles above his head was a flat, endless plane, very much like the surface of the red dwarf star from which he had emerged into this solar system. It was cherry red, and little nodules of brighter luminescence appeared at random, wandered around for a while like living things, and then faded out into the glowing background. If Bowman had possessed a trace of superstition, he could easily have imagined that this was the roof of Hell. There was no mark to show how he had passed through it, to enter this underworld.
He waited, on an infinite black plain, beneath an infinite glowing sky. And presently, for the first time in all his travels, he heard a sound.
It was a gentle throbbing, like the beating of a drum, that grew louder and more insistent second by second. He did not attempt to fight its compulsion, but let its hypnotic rhythm take over control of his mind.
And now, light was appearing in the achi
ng darkness of the plain. First there was a single star, that moved swiftly to trace out a line, then the line moved, to make a horizontal square; then the square lifted, leaving its presence where it had passed, until the ghost of a crystal cube hung before Bowman's eyes.
The drumming became louder, more complex. Now there were rhythms moving against each other, like clashing waves on the surface of a stormy sea. And the crystal cube began to glow.
First it lost its transparency and became suffused with a pale mist, within which moved tantalizing, ill-defined phantoms. They coalesced into bars of light and shadow, then formed intermeshed, spoked patterns that began to rotate.
Now the turning wheels of light merged together, and their spokes fused into luminous bars that slowly receded into the distance. They split into pairs, and the resulting sets of lines started to oscillate across each other, continually changing their angle of intersection. Fantastic, fleeting geometrical patterns flickered in and out of existence as the glowing grids meshed and unmeshed, and the hominid watched from its metal cave-wide-eyed, slack jawed, and wholly receptive.
