Lavon shifted his position on the plant frond, where he had been sitting in order to overlook the harvesting of an experimental crop of blue-green, oil-rich algae drifting in a clotted mass close to the top of the sky, and scratched his back gently against the coarse bole. The protos were seldom wrong, after all. Their lack of creativity, their inability to think an original thought, was a gift as well as a limitation. It allowed them to see and feel things at all times as they were—not as they hoped they might be, for they had no ability to hope, either.
“La-von! Laa-vah-on!”
The long halloo came floating up from the sleepy depths. Propping one hand against the top of the frond, Lavon bent and looked down. One of the harvesters was looking up at him, holding loosely the adze with which he had been splitting free from the raft the glutinous tetrads of the algae.
“I’m up here. What’s the matter?”
“We have the ripened quadrant cut free. Shall we tow it away?”
“Tow it away,” Lavon said, with a lazy gesture. He leaned back again. At the same instant, a brilliant reddish glory burst into being above him, and cast itself down toward the depths like mesh after mesh of the finest drawn gold. The great light which lived above the sky during the day, brightening or dimming according to some pattern no Shar ever had fathomed, was blooming again.
Few men, caught in the warm glow of that light, could resist looking up at it—especially when the top of the sky itself wrinkled and smiled just a moment’s climb or swim away. Yet, as always, Lavon’s bemused upward look gave him back nothing but his own distorted, hobbling reflection, and a reflection of the plant on which he rested. Here was the upper limit, the third of the three surfaces of the universe.
The first surface was the bottom, where the water ended.
The second surface was the thermocline, the invisible division between the colder waters of the bottom and the warm, light waters of the sky. During the height of the warm weather, the thermocline was so definite a division as to make for good sledding and for chilly passage. A real interface formed between the cold, denser bottom waters and the warm reaches above, and maintained itself almost for the whole of the warm season.
The third surface was the sky. One could no more pass through that surface that one could penetrate the bottom, nor was there any better reason to try. There the universe ended. The light which played over it daily, waxing and waning as it chose, seemed one of its properties.
Toward the end of the season, the water gradually became colder and more difficult to breathe, while at the same time the light grew duller and stayed for shorter periods between darknesses. Slow currents started to move. The high waters turned chill and started to fall. The bottom mud stirred and smoked away, carrying with it the spores of the fields of fungi. The thermocline tossed, became choppy, and melted away. The sky began to fog with particles of soft silt carried up from the bottom, the walls, the corners of the universe. Before very long, the whole world was cold, flocculent with dying creatures.
Then the protos encysted; the bacteria, even most of the plants—and, not long afterward, men, too—curled up in their oil-filled amber shells. The world died until the first current of warm water broke the winter silence.
“La-von!”
Just after the long call, a shining bubble rose past La-von. He reached out and poked it, but it bounded away from his sharp thumb. The gas bubbles which rose from the bottom in late summer were almost invulnerable— and when some especially hard blow or edge did penetrate them, they broke into smaller bubbles which nothing could touch, leaving behind a remarkably bad smell.
Gas. There was no water inside a bubble. A man who got inside a bubble would have nothing to breathe.
But, of course, it was impossible to enter a bubble. The surface tension was too strong. As strong as Shar’s metal plates. As strong as the top of the sky.
As strong as the top of the sky. And above that—once the bubble was broken—a world of gas instead of water? Were all worlds bubbles of water -drifting in gas?
If it were so, travel between them would be out of the question, since it would be impossible to pierce the sky to begin with. Nor did the infant cosmography include any provisions for bottoms for the worlds.
And yet some of the local creatures did burrow into the bottom, quite deeply, seeking something in those depths which was beyond the reach of Man. Even the surface of the ooze, in high summer, crawled with tiny creatures for which mud was a natural medium. Man, too, passed freely between the two countries of water which were divided by the thermocline, though many of the creatures with which he lived could not pass that line at all, once it had established itself.
And if the new universe of which Shar had spoken existed at all, it had to exist beyond the sky, where the light was. Why could not the sky be passed, after all? The fact that bubbles could sometimes be broken showed that the surface skin that formed between water and gas wasn’t completely invulnerable. Had it ever been tried?
Lavon did not suppose that one man could butt his way through the top of the sky, any more than he could burrow into the bottom, but there might be ways around the difficulty. Here at his back, for instance, was a plant which gave every appearance of continuing beyond the sky.
It had always been assumed that the plants died where they touched the sky. For the most part, they did, for frequently the dead extension could be seen, leached and yellow, the boxes of its component cells empty, floating embedded in the perfect mirror. But some were simply chopped off, like the one which sheltered him now. Perhaps that was only an illusion, and instead it soared indefinitely into some other place—some place where men might once have been born, and might still live ...
The plates were gone. There was only one other way to find out.
Determinedly, Lavon began to climb toward the wavering mirror of the sky. His thorn-thumbed feet trampled obliviously upon the clustered sheathes of fragile stippled diatoms. The tulip-heads of Vortae, placid and murmurous cousins of Para, retracted startledly out of his way upon coiling stalks, to make silly gossip behind him.
Lavon did not hear them. He continued to climb doggedly toward the light, his fingers and toes gripping the plant-bole.
“Lavon! Where are you going? Lavon!”
He leaned out and looked down. The man with the adze, a doll-like figure, was beckoning to him from a patch of blue-green retreating over a violet abyss. Dizzily he looked away, clinging to the bole; he had never been so high before. He had, of course, nothing to fear from falling, but the fear was in his heritage. Then he began to climb again.
After a while, he touched the sky with one hand. He stopped to breathe. Curious bacteria gathered about the base of his thumb where blood from a small cut was fogging away, scattered at his gesture, and wriggled mindlessly back toward the dull red lure.
He waited until he no longer felt winded, and resumed climbing. The sky pressed down against the top of his head, against the back of his neck, against his shoulders. It seemed to give slightly, with a tough, frictionless elasticity. The water here was intensely bright, and quite colorless. He climbed another step, driving his shoulders against that enormous weight.
He might as well have tried to penetrate a cliff.
Again he had to rest. While he panted, he made a curious discovery. All around the bole of the water plant, the steel surface of the sky curved upward, making a kind of sheathe. He found that he would insert his hand into it—there was almost enough space to admit his head as well. Clinging closely to the bole, he looked up into the inside of the sheathe, probing it with his injured hand. The glare was blinding.
There was a kind of soundless explosion. His whole wrist was suddenly encircled in an intense, impersonal grip, as if it were being cut in two. In blind astonishment, he lunged upward.
The ring of pain travelled smoothly down his upflung arm as he rose, was suddenly around his shoulders and chest. Another lunge and his knees were being squeezed in the circular vise. Another—
/>
Something was horribly wrong. He clung to the bole and tried to gasp, but there was—nothing to breathe.
The water came streaming out of his body, from his mouth, his nostrils, the spiracles in his sides, spurting in tangible jets. An intense and fiery itching crawled over the surface of his body. At each spasm, long knives ran into him, and from a great distance he heard more water being expelled from his book-lungs in an obscene, frothy sputtering. Inside his head, a patch of fire began to eat away at the floor of his nasal cavity.
Lavon was drowning.
With a final convulsion, he kicked himself away from the splintery bole, and fell. A hard impact shook him; and then the water, which had clung to him so tightly when he had first attempted to leave it, took him back with cold violence.
Sprawling and tumbling grotesquely, he drifted, down and down and down, toward the bottom.
~ * ~
For many days, Lavon lay curled insensibly in his spore, as if in the winter sleep. The shock of cold which he had felt on re-entering his native universe had been taken by his body as a sign of coming winter, as it had taken the oxygen-starvation of his brief sojourn above the sky. The spore-forming glands had at once begun to function.
Had it not been for this, Lavon would surely have died. The danger of drowning disappeared even as he fell, as the air bubbled out of his lungs and readmitted the life-giving water. But for acute dessication and third degree sunburn, the sunken universe knew no remedy. The healing amnionic fluid generated by the spore-forming glands, after the transparent amber sphere had enclosed him, offered Lavon his only chance.
The brown sphere was spotted after some days by a prowling ameba, quiescent in the eternal winter of the bottom. Down there the temperature was always an even 4°, no matter what the season, but it was unheard of that a spore should be found there while the high epilimnion was still warm and rich in oxygen.
Within an hour, the spore was surrounded by scores of astonished protos, jostling each other to bump their blunt eyeless prows against the shell. Another hour later, a squad of worried men came plunging from the castles far above to press their own noses against the transparent wall. Then swift orders were given.
Four Para grouped themselves about the amber sphere, and there was a subdued explosion as the trichocysts which lay embedded at the bases of their cilia, just under the pellicle, burst and cast fine lines of a quickly solidifying liquid into the water. The four Paras thrummed and lifted, tugging.
Lavon’s spore swayed gently in the mud and then rose slowly, entangled in the web. Nearby, a Noc cast a cold pulsating glow over the operation—not for the Paras, who did not need the light, but for the baffled knot of men. The sleeping figure of Lavon, head bowed, knees drawn up to its chest, revolved with an absurd solemnity inside the shell as it was moved.
“Take him to Shar, Para.”
The young Shar justified, by minding his own business, the traditional wisdom with which his hereditary office had invested him. He observed at once that there was nothing he could do for the encysted Lavon which would not be classifiable as simple meddling.
He had the sphere deposited in a high tower room of his castle, where there was plenty of light and the water was warm, which should suggest to the estivating form that spring was again on the way. Beyond that, he simply sat and watched, and kept his speculations to himself.
Inside the spore, Lavon’s body seemed rapidly to be shedding its skin, in long strips and patches. Gradually, his curious shrunkenness disappeared. His withered arms and legs and sunken abdomen filled out again.
The days went by while Shar watched. Finally he could discern no more changes, and, on a hunch, had the spore taken up to the top of the tower, into the direct daylight.
An hour later, Lavon moved in his amber prison.
He uncurled and stretched, turned blank eyes up toward the light. His expression was that of a man who had not yet awakened from a ferocious nightmare. His whole body shone with a strange pink newness.
Shar knocked gently on the walls of the spore. Lavon turned his blind face toward the sound, life coming into his eyes. He smiled tentatively and braced his hands and feet against the inner wall of the shell.
The whole sphere fell abruptly to pieces with a sharp crackling. The amnionic fluid dissipated around him and Shar, carrying away with it the suggestive odor of a bitter struggle against death.
Lavon stood among the shards and looked at Shar silently. At last he said:
“Shar—I’ve been above the sky.”
“I know,” Shar said gently.
Again Lavon was silent. Shar said, “Don’t be humble, Lavon. You’ve done an epoch-making thing. It nearly cost you your life. You must tell me the rest—all of it.”
“The rest?”
“You taught me a lot while you slept. Or are you still opposed to ‘useless’ knowledge?”
Lavon could say nothing. He no longer could tell what he knew from what he wanted to know. He had only one question left, but he could not utter it. He could only look dumbly into Shar’s delicate face.
“You have answered me,” Shar said, even more gently than before. “Come, my friend; join me at my table. We will plan our journey to the stars.”
~ * ~
There were five of them around Shar’s big table: Shar himself, Lavon, and the three assistants assigned by custom to the Shars from the families Than, Tanol and Stravol. The duties of these three men—or, sometimes, women —under many previous Shars had been simple and onerous: to put into effect in the field the genetic changes in the food crops which the Shar himself had worked out in laboratory tanks and flats. Under other Shars more interested in metal-working or in chemistry, they had been smudged men—diggers, rock-splitters, fashioners and cleaners of apparatus.
Under Shar XVI, however, the three assistants had been more envied than usual among the rest of Lavon’s people, for they seemed to do very little work of any kind. They spent long hours of every day and evening talking with Shar in his chambers, poring over records, making mysterious scratch-marks on slate, or just looking at simple things about which there was no obvious mystery. Sometimes they actually worked with Shar in his laboratory, but mostly they just sat.
Shar XVI had, as a matter of fact, discovered certain rudimentary rules of inquiry which, as he explained it to Lavon, he had recognized as tools of enormous power. He had become more interested in passing these on to future workers than in the seductions of any specific experiment, the journey to the stars perhaps excepted. The Than, Tanol and Stravol of his generation were having scientific method pounded into their heads, a procedure they maintained was sometimes more painful than heaving a thousand rocks.
That they were the first of Lavon’s people to be taxed with the problem of constructing a spaceship was, therefore, inevitable. The results lay on the table: three models, made of diatom-glass, strands of algae, flexible bits of cellulose, flakes of stonewort, slivers of wood, and organic glues collected from the secretions of a score of different plants and animals.
Lavon picked up the nearest one, a fragile spherical construction inside which little beads of dark-brown lava —actually bricks of rotifer-spittle painfully chipped free from the wall of an unused castle—moved freely back and forth in a kind of ball-bearing race. “Now whose is this one?” he said, turning the sphere curiously to and fro.
“That’s mine,” Tanol said. “Frankly I don’t think it comes anywhere near meeting all the requirements. It’s just the only design I could arrive at that I think we could build with the materials and knowledge we have.”
“But how does it work?”
“Hand it here a moment, Lavon. This bladder you see inside at the center, with the hollow spyrogyra straws leading out from it to the skin of the ship, is a bouyancy tank. The idea is that we trap ourselves a big gas-bubble as it rises from the bottom and install it in the tank. Probably we’ll have to do that piecemeal. Then the ship rises to the sky on the bouyancy of the bubble. The lit
tle paddles, here along these two bands on the outside, rotate when the crew—that’s these bricks you hear shaking around inside—walks a treadmill that runs around the inside of the hull; they paddle us over to the edge of the sky. Then we pull the paddles in—they fold over into slots, like this— and, still by weight-transfer from the inside, roll ourselves up the slope until we’re out in space. When we hit another world and enter the water again, we let the gas out of the tank gradually through the exhaust tubes represented by these straws, and sink down to a landing at a controlled rate.”
“Very ingenious,” Shar said thoughtfully. “But I can foresee some difficulties. For one thing, the design lacks stability.”
“Yes, it does,” Tanol agreed. “And keeping it in motion is going to require a lot of footwork. On the other hand, the biggest expenditure of energy involved in the whole trip is going to be getting the machine up to the sky in the first place, and with this design that’s taken care of—as a matter of fact, once the bubble’s installed, we’ll have to keep the ship tied down until we’re ready to go.”
“How about letting the gas out?” Lavon said. “Will it go out through those little tubes when we want it to? Won’t it just cling to the walls of the tank instead? The skin between water and gas is pretty difficult to deform—to that I can testify.”
Tanol frowned. “That I don’t know. Don’t forget that the tubes will be large in the real ship, not just straws as they are in the model.”
“Bigger than a man’s body?” Than said.
“No, hardly. Maybe as big, though, as a man’s head.”
“Won’t work,” Than said tersely. “I tried it. You can’t lead a bubble through a pipe that small. As Lavon said, it clings to the inside of the tube and won’t be budged. If we build this ship, we’ll just have to abandon it once we hit our new world.”
