“The sea is about the same,” Eunice said. “I’ve found some of the larger simple metazoans—jellyfish and so on—and some crayfish almost as big as lobsters. But it’s normal to find saltwater species running larger than freshwater. And there’s the usual plankton and nannoplankton population.”
“In short,” Chatvieux said, “we’ll survive here if we fight.”
“Wait a minute,” la Ventura said. “You’ve just finished telling me that we wouldn’t survive. And you were talking about us, the seven of us here, not about the genus man, because we don’t have our germ-cell banks anymore. What’s—”
“We don’t have the banks. But we ourselves can contribute germ-cells, Paul. I’ll get to that in a moment.” Chatvieux turned to Saltonstall. “Martin, what would you think of our taking to the sea? We came out of it once, long ago; maybe we could come out of it again on Hydrot.”
“No good,” Saltonstall said immediately. “I like the idea, but I don’t think this planet ever heard of Swinburne, or Homer, either. Looking at it as a colonization problem alone, as if we weren’t involved in it ourselves, I wouldn’t give you an Oc dollar for epi oinopa ponton. The evolutionary pressure there is too high, the competition from other species is prohibitive; seeding the sea should be the last thing we attempt, not the first. The colonists wouldn’t have a chance to learn a thing before they’d be gobbled up.”
“Why?” la Ventura said. Once more, the death in his stomach was becoming hard to placate.
“Eunice, do your seagoing coelenterates include anything like the Portuguese man-of-war?”
The ecologist nodded.
“There’s your answer, Paul,” Saltonstall said. “The sea is out. It’s got to be freshwater, where the competing creatures are less formidable and there are more places to hide.”
“We can’t compete with a jellyfish?” la Ventura asked, swallowing.
“No, Paul,” Chatvieux said. “Not with one that dangerous. The pantropes make adaptations, not gods. They take human germ-cells—in this case, our own, since our bank was wiped out in the crash—and modify them genetically toward those of creatures who can live in any reasonable environment. The result will be manlike, and intelligent. It usually shows the donors’ personality patterns, too, since the modifications are usually made mostly in the morphology, not so much in the mind, of the resulting individual.
“But we can’t transmit memory. The adapted man is worse than a child in the new environment. He has no history, no techniques, no precedents, not even a language. In the usual colonization project, like the Tellura affair, the seeding teams more or less take him through elementary school before they leave the planet to him, but we won’t survive long enough to give such instruction. We’ll have to design our colonists with plenty of built-in protections and locate them in the most favorable environment possible, so that at least some of them will survive learning by experience alone.”
The pilot thought about it, but nothing occurred to him which did not make the disaster seem realer and more intimate with each passing second. Joan Heath moved slightly closer to him. “One of the new creatures can have my personality pattern, but it won’t be able to remember being me. Is that right?”
“That’s right. In the present situation we’ll probably make our colonists haploid, so that some of them, perhaps many, will have a heredity traceable to you alone. There may be just the faintest of residuums of identity—pantropy’s given us some data to support the old Jungian notion of ancestral memory. But we’re all going to die on Hydrot, Paul, as self-conscious persons. There’s no avoiding that. Somewhere we’ll leave behind people who behave as we would, think and feel as we would, but who won’t remember la Ventura, or Dr. Chatvieux, or Joan Heath, or the Earth.”
The pilot said nothing more. There was a gray taste in his mouth.
“Saltonstall, what would you recommend as a form?”
The pantropist pulled reflectively at his nose. “Webbed extremities, of course, with thumbs and big toes heavy and thornlike for defense until the creature has had a chance to learn. Smaller external ears, and the eardrum larger and closer to the outer end of the ear canal. We’re going to have to reorganize the water-conservation system, I think; the glomerular kidney is perfectly suitable for living in freshwater, but the business of living immersed, inside and out, for a creature with a salty inside means that the osmotic pressure inside is going to be higher than outside, so that the kidneys are going to have to be pumping virtually all the time. Under the circumstances we’d best step up production of urine, and that means the anti-diuretic function of the pituitary gland is going to have to be abrogated, for all practical purposes.”
“What about respiration?”
“Hm,” Saltonstall said. “I suppose book-lungs, like some of the arachnids have. They can be supplied by intercostal spiracles. They’re gradually adaptable to atmosphere-breathing, if our colonist ever decides to come out of the water. Just to provide for that possibility. I’d suggest that the nose be retained, maintaining the nasal cavity as a part of the otological system, but cutting off the cavity from the larynx with a membrane of cells that are supplied with oxygen by direct irrigation, rather than by the circulatory system. Such a membrane wouldn’t survive for many generations, once the creature took to living out of the water even for part of its lifetime; it’d go through two or three generations as an amphibian, and then one day it’d suddenly find itself breathing through its larynx again.”
“Ingenious,” Chatvieux said.
“Also, Dr. Chatvieux, I’d suggest that we have it adopt sporulation. As an aquatic animal, our colonist is going to have an indefinite lifespan, but we’ll have to give it a breeding cycle of about six weeks to keep up its numbers during the learning period; so there’ll have to be a definite break of some duration in its active year. Otherwise it’ll hit the population problem before it’s learned enough to cope with it.”
“And it’d be better if our colonists could winter over inside a good, hard shell,” Eunice Wagner added in agreement. “So sporulation’s the obvious answer. Many other microscopic creatures have it.”
“Microscopic?” Phil said incredulously.
“Certainly,” Chatvieux said, amused. “We can’t very well crowd a six-foot man into a two-foot puddle. But that raises a question. We’ll have tough competition from the rotifers, and some of them aren’t strictly microscopic; for that matter even some of the protozoa can be seen with the naked eye, just barely, with dark-field illumination. I don’t think your average colonist should run much under two hundred fifty microns, Saltonstall. Give them a chance to slug it out.”
“I was thinking of making them twice that big.”
“Then they’d be the biggest animals in their environment,” Eunice Wagner pointed out, “and won’t ever develop any skills. Besides, if you make them about rotifer size, it will give them an incentive for pushing out the castle-building rotifers, and occupying the castles themselves, as dwellings.”
Chatvieux nodded. “All right, let’s get started. While the pantropes are being calibrated, the rest of us can put our heads together on leaving a record for these people. We’ll micro-engrave the record on a set of corrosion-proof metal leaves, of a size our colonists can handle conveniently. We can tell them, very simply, what happened, and plant a few suggestions that there’s more to the universe than what they find in their puddles. Someday they may puzzle it out.”
“Question,” Eunice Wagner said. “Are we going to tell them they’re microscopic? I’m opposed to it. It may saddle their entire early history with a gods-and-demons mythology that they’d be better off without.”
“Yes, we are,” Chatvieux said, and la Ventura could tell by the change in the tone of his voice that he was speaking now as their senior on the expedition. “These people will be of the race of men, Eunice. We want them to win their way back into the community of men. They are not toys, to be protected from the truth forever in a freshwater womb.”
“Besides,” Saltonstall observed, “they won’t get the record translated at any time in their early history. They’ll have to develop a written language of their own, and it will be impossible for us to leave them any sort of Rosetta stone or other key. By the time they can decipher the truth, they should be ready for it.”
“I’ll make that official,” Venezuelos said unexpectedly. And that was that.
And then, essentially, it was all over. They contributed the cells that the pantropes would need. Privately, la Ventura and Joan Heath went to Chatvieux and asked to contribute jointly; but the scientist said that the microscopic men were to be haploid, in order to give them a minute cellular structure, with nuclei as small as Earthly rickettsiae, and therefore each person had to give germ-cells individually—there would be no use for zygotes. So even that consolation was denied them; in death they would have no children, but be instead as alone as ever.
They helped, as far as they could, with the text of the message which was to go on the metal leaves. They had their personality patterns recorded. They went through the motions. Already they were beginning to be hungry; the sea-crayfish, the only things on Hydrot big enough to eat, lived in water too deep and cold for subsistence fishing.
After la Ventura had set his control board to rights—a useless gesture, but a habit he had been taught to respect, and which in an obscure way made things a little easier to bear—he was out of it. He sat by himself at the far end of the rock ledge, watching Tau Ceti go redly down, chucking pebbles into the nearest pond.
After a while Joan Heath came silently up behind him, and sat down too. He took her hand. The glare of the red sun was almost extinguished now, and together they watched it go, with la Ventura, at least, wondering somberly which nameless puddle was to be his Lethe.
He never found out, of course. None of them did.
CYCLE ONE
In a forgotten corner of the galaxy, the watery world of Hydrot hurtles endlessly around the red star Tau Ceti. For many months its single small continent has been snowbound, and the many pools and lakes which dot the continent have been locked in the grip of the ice. Now, however, the red sun swings closer and closer to the zenith in Hydrot’s sky; the snow rushes in torrents toward the eternal ocean, and the ice recedes toward the shores of the lakes and ponds….
The first thing to reach the consciousness of the sleeping Lavon was a small, intermittent scratching sound. This was followed by a disquieting sensation in his body, as if the world—and Lavon with it—were being rocked back and forth. He stirred uneasily, without opening his eyes. His vastly slowed metabolism made him feel inert and queasy, and the rocking did not help. At his slight motion, however, both the sound and the motion became more insistent.
It seemed to take days for the fog over his brain to clear, but whatever was causing the disturbance would not let him rest. With a groan he forced his eyelids open and made an abrupt gesture with one webbed hand. By the waves of phosphorescence which echoed away from his fingers at the motion, he could see that the smooth amber walls of his spherical shell were unbroken. He tried to peer through them, but he could see nothing but darkness outside. Well, that was natural; the amniotic fluid inside the spore would generate light, but ordinary water did not, no matter how vigorously it was stirred.
Whatever was outside the sphere was rocking it again, with the same whispering friction against its shell. Probably some nosy diatom, Lavon thought sleepily, trying to butt its way through an object it was too stupid to go around. Or some early hunter, yearning for a taste of the morsel inside the spore. Well, let it worry itself; Lavon had no intention of breaking the shell just yet. The fluid in which he had slept for so many months had held his body processes static, and had slowed his mind. Once out into the water, he would have to start breathing and looking for food again, and he could tell by the unrelieved darkness outside that it was too early in the spring to begin thinking about that.
He flexed his fingers reflectively, in the disharmonic motion from little finger to thumb that no animal but man can copy, and watched the widening wave fronts of greenish light rebound in larger arcs from the curved spore walls. Here he was, curled up quite comfortably in a little amber ball, where he could stay until even the depths were warm and light. At this moment there was probably still some ice on the sky, and certainly there would not be much to eat as yet. Not that there was ever much, what with the voracious rotifers coming awake too with the first gust of warm water—
The rotifers! That was it. There was a plan afoot to drive them out. Memory returned in an unwelcome rush. As if to help it, the spore rocked again. That was probably one of the Protos, trying to awaken him; nothing man-eating ever came to the Bottom this early. He had left an early call with the Paras, and now the time had come, as cold and early and dark as he had thought he wanted it.
Reluctantly, Lavon uncurled, planting his webbed toes and arching his backbone as hard as he could, pressing with his whole body against his amber prison. With small, sharp, crepitating sounds, a network of cracks raced through the translucent shell.
Then the spore wall dissolved into a thousand brittle shards, and he was shivering violently with the onslaught of the icy water. The warmer fluid of his winter cell dissipated silently, a faint glowing fog. In the brief light he saw, not far from him, a familiar shape: a transparent, bubble-filled cylinder, a colorless slipper of jelly, spirally grooved, almost as long as he was tall. Its surface was furred with gently vibrating fine hairs, thickened at the base.
The light went out. The Proto said nothing; it waited while Lavon choked and coughed, expelling the last remnants of the spore fluid from his book-lungs and sucking in the pure, ice-cold water.
“Para?” Lavon said at last. “Already?”
“Already,” the invisible cilia vibrated in even, emotionless tones. Each separate hairlike process buzzed at an independent, changing rate; the resulting sound waves spread through the water, intermodulating, reinforcing or cancelling each other. The aggregate wave-front, by the time it reached human ears, was rather eerie, but nevertheless recognizable human speech. “This is the time, Lavon.”
“Time and more than time,” another voice said from the returned darkness. “If we are to drive Flosc from his castles.”
“Who’s that?” Lavon said, turning futilely toward the new voice.
“I am Para also, Lavon. We are sixteen since the awakening. If you could reproduce as rapidly as we—”
“Brains are better than numbers,” Lavon said. “As the Eaters will find out soon enough.”
“What shall we do, Lavon?”
The man drew up his knees and sank to the cold mud of the Bottom to think. Something wriggled under his buttocks and a tiny spirillum corkscrewed away, identifiable only by feel. He let it go; he was not hungry yet, and he had the Eaters—the rotifers—to think about. Before long they would be swarming in the upper reaches of the sky, devouring everything, even men when they could catch them, even their natural enemies the Protos now and then. And whether or not the Protos could be organized to battle them was a question still to be tested.
Brains are better than numbers; even that, as a proposition, was still to be tested. The Protos, after all, were intelligent after their fashion; and they knew their world, as the men did not. Lavon could still remember how hard it had been for him to get straight in his head the various clans of beings in this world, and to make sense of their confused names; his tutor Shar had drilled him unmercifully until it had begun to penetrate.
When you said “man,” you meant creatures that, generally speaking, looked alike. The bacteria were of three kinds, the rods and the globes and the spirals, but they were all tiny and edible, so he had learned to differentiate them quickly. When it came to the Protos, identification became a real problem. Para here was a Proto, but he certainly looked very different from Stent and his family, and the family of Didin was unlike both. Anything, as it turned out, that was not green and had a visible nucleus was
a Proto, no matter how strange its shape might be. The Eaters were all different, too, and some of them were as beautiful as the fruiting crowns of water-plants; but all of them were deadly, and all had the whirling crown of cilia which could suck you into the incessantly grinding mastax in a moment. Everything which was green and had an engraved shell of glass Shar had called a diatom, dredging the strange word as he dredged them all from some Bottom in his skull which none of the rest of them could reach, and even Shar could not explain.
Lavon arose quickly. “We need Shar,” he said. “Where is his spore?”
“On a plant frond, far up near the sky.”
Idiot! The old man would never think of safety. To sleep near the sky, where he might be snatched up and borne off by any Eater to chance by when he emerged, sluggish with winter’s long sleep! How could a wise man be so foolish?
“We’ll have to hurry. Show me the way.”
“Soon; wait,” one of the Paras said. “You cannot see. Noc is foraging nearby.” There was a small stir in the texture of the darkness as the swift cylinder shot away.
“Why do we need Shar?” the other Para said.
“For his brains, Para. He is a thinker.”
“But his thoughts are water. Since he taught the Proto man’s language, he has forgotten to think of the Eaters. He thinks forever of the mystery of how man came here. It is a mystery—even the Eaters are not like man. But understanding it will not help us to live.”
Lavon turned blindly toward the creature. “Para, tell me something. Why do the Protos side with us? With man, I mean? Why do you need us? The Eaters fear you.”
There was a short silence. When the Para spoke again, the vibrations of its voice were more blurred than before, more even, more devoid of any understandable feeling.
“We live in this world,” the Para said. “We are of it. We rule it. We came to that state long before the coming of men, in long warfare with the Eaters. But we think as the Eaters do, we do not plan, we share our knowledge, and we exist. Men plan; men lead; men are different from each other; men want to remake the world. And they hate the Eaters, as we do. We will help.”
