To Kworn the object was a roadblock, threatening his life.
But it was also a high road to a magnificent future!

The Ul Kworn paused in his search for food, extended his eye and considered the thing that blocked his path.

He hadn't notice the obstacle until he had almost touched it. His attention had been focused upon gleaning every feeder large enough to be edible from the lichens that covered his feeding strip. But the unexpected warmth radiating from the object had startled him. Sundown was at hand. There should be nothing living or non-living that radiated a fraction of the heat that was coming from the gleaming metal wall which lay before him. He expanded his mantle to trap the warmth as he pushed his eye upward to look over the top. It wasn't high, just high enough to be a nuisance. It curved away from him toward the boundaries of his strip, extending completely across the width of his land.

A dim racial memory told him that this was an artefact, a product of the days when the Folk had leisure to dream and time to build. It had probably been built by his remote ancestors millennia ago and had just recently been uncovered from its hiding place beneath the sand. These metal objects kept appearing and disappearing as the sands shifted to the force of the wind. He had seen them before, but never a piece so large or so well preserved. It shone as though it had been made yesterday, gleaming with a soft silvery luster against the blue-black darkness of the sky.

As his eye cleared the top of the wall, he quivered with shock and astonishment. For it was not a wall as he had thought. Instead, it was the edge of a huge metal disc fifty raads in diameter. And that wasn't all of it. Three thick columns of metal extended upward from the disc, leaning inward as they rose into the sky. High overhead, almost beyond the range of accurate vision, they converged to support an immense cylinder set vertically to the ground. The cylinder was almost as great in diameter as the disc upon which his eye first rested. It loomed overhead, and he had a queasy feeling that it was about to fall and crush him. Strange jointed excresences studded its surface, and in its side, some two-thirds of the way up, two smaller cylinders projected from the bigger one. They were set a little distance apart, divided by a vertical row of four black designs, and pointed straight down his feeding strip.

The Ul Kworn eyed the giant structure with disgust and puzzlement. The storm that had uncovered it must have been a great one to have blown so much sand away. It was just his fortune to have the thing squatting in his path! His mantle darkened with anger. Why was it that everything happened to him? Why couldn't it have lain in someone else's way, upon the land of one of his neighbors? It blocked him from nearly three thousand square raads of life-sustaining soil. To cross it would require energy he could not spare. Why couldn't it have been on the Ul Caada's or the Ul Varsi's strip—or any other of the numberless Folk? Why did he have to be faced with this roadblock?

He couldn't go around it since it extended beyond his territory and, therefore, he'd have to waste precious energy propelling his mass up the wall and across the smooth shining surface of the disc—all of which would have to be done without food, since his eye could see no lichen growing upon the shiny metal surface.

The chill of evening had settled on the land. Most of the Folk were already wrapped in their mantles, conserving their energy until the dawn would warm them into life. But Kworn felt no need to estivate. It was warm enough beside the wall.

The air shimmered as it cooled. Microcrystals of ice formed upon the legs of the structure, outlining them in shimmering contrast to the drab shadowy landscape, with its gray-green cover of lichens stippled with the purple balls of the lichen feeders that clung to them. Beyond Kworn and his neighbors, spaced twenty raads apart, the mantled bodies of the Folk stretched in a long single line across the rolling landscape, vanishing into the darkness. Behind this line, a day's travel to the rear, another line of the Folk was following. Behind them was yet another. There were none ahead, for the Ul Kworn and the other Ul were the elders of the Folk and moved along in the first rank where their maturity and ability to reproduce had placed them according to the Law.

Caada and Varsi stirred restlessly, stimulated to movement by the heat radiating from the obstacle, but compelled by the Law to hold their place in the ranks until the sun's return would stimulate the others. Their dark crimson mantles rippled over the soil as they sent restless pseudopods to the boundaries of their strips.

They were anxious in their attempt to communicate with the Ul Kworn.

But Kworn wasn't ready to communicate. He held aloof as he sent a thin pseudopod out toward the gleaming wall in front of him. He was squandering energy; but he reasoned that he had better learn all he could about this thing before he attempted to cross it tomorrow, regardless of what it cost.

It was obvious that he would have to cross it, for the Law was specific about encroachment upon a neighbor's territory. No member of the Folk shall trespass the feeding land of another during the Time of Travel except with published permission. Trespass shall be punished by the ejection of the offender from his place in rank.

And that was equivalent to a death sentence.

He could ask Caada or Varsi for permission, but he was virtually certain that he wouldn't get it. He wasn't on particularly good terms with his neighbors. Caada was querulous, old and selfish. He had not reproduced this season and his vitality was low. He was forever hungry and not averse to slipping a sly pseudopod across the boundaries of his land to poach upon that of his neighbor. Kworn had warned him some time ago that he would not tolerate encroachment and would call for a group judgment if there was any poaching. And since the Folk were physically incapable of lying to one another, Caada would be banished. After that Caada kept his peace, but his dislike for Kworn was always evident.

But Varsi who held the land on Kworn's right was worse. He had advanced to Ul status only a year ago. At that time there had been rumors among the Folk about illicit feeding and stealing of germ plasm from the smaller and weaker members of the race. But that could not be proved, and many young Folk died in the grim process of growing to maturity. Kworn shrugged. If Varsi was an example of the younger generation, society was heading hell-bent toward Emptiness. He had no love for the pushing, aggressive youngster who crowded out to the very borders of his domain, pressing against his neighbors, alert and aggressive toward the slightest accidental spillover into his territory. What was worse, Varsi had reproduced successfully this year and thus had rejuvenated. Kworn's own attempt had been only partially successful. His energy reserves hadn't been great enough to produce a viable offspring, and the rejuvenation process in his body had only gone to partial completion. It would be enough to get him to the winter feeding grounds. But as insurance he had taken a place beside Caada, who was certain to go into Emptiness if the feeding en route was bad.

Still, he hadn't figured that he would have Varsi beside him.

He consoled himself with the thought that others might have as bad neighbors as he. But he would never make the ultimate mistake of exchanging germ plasm with either of his neighbors, not even if his fertility and his position depended upon it. Cells like theirs would do nothing to improve the sense of discipline and order he had so carefully developed in his own. His offspring were courteous and honorable, a credit to the Folk and to the name of Kworn. A father should be proud of his offspring, so that when they developed to the point where they could have descendants, he would not be ashamed of what they would produce. An Ul, Kworn thought grimly, should have some sense of responsibility toward the all-important future of the race.

His anger died as he exerted synergic control. Anger was a waster of energy, a luxury he couldn't afford. He had little enough as it was. It had been a bad year. Spring was late, and winter had come early. The summer had been dry and the lichens in the feeding grounds had grown poorly. The tiny, bulbous lichen feeders, the main source of food for the Folk, had failed to ripen to their usual succulent fullness. They had been poor, shrunken things, hardly worth ingesting. And those along the route to the winter feeding grounds were no better.

Glumly he touched the wall before him with a tactile filament. It was uncomfortably warm, smooth and slippery to the touch. He felt it delicately, noting the almost microscopic horizontal ridges on the wall's surface. He palpated with relief. The thing was climbable. But even as he relaxed, he recoiled, the filament writhing in agony! The wall had burned his flesh! Faint threads of vapor rose from where he had touched the metal, freezing instantly in the chill air. He pinched off the filament in an automatic protective constriction of his cells. The pain ceased instantly, but the burning memory was so poignant that his mantle twitched and shuddered convulsively for some time before the reflexes died.

Thoughtfully he ingested his severed member. With a sense of numbing shock he realized that he would be unable to pass across the disc. The implications chilled him. If he could not pass, his land beyond the roadblock would be vacant and open to preemption by his neighbors. Nor could he wait until they had passed and rejoin them later. The Law was specific on that point. If one of the Folk lags behind in his rank, his land becomes vacant and open to his neighbors. Nor can one who has lagged behind reclaim his land by moving forward. He who abandons his position, abandons it permanently.

Wryly, he reflected that it was this very Law that had impelled him to take a position beside the Ul Caada. And, of course, his neighbors knew the Law as well as he. It was a part of them, a part of their cells even before they split off from their parent. It would be the acme of folly to expect that neighbors like Varsi or Caada would allow him to pass over their land and hold his place in rank.

Bitterness flooded him with a stimulation so piercing that Caada extended a communication filament to project a question. "What is this thing which lies upon your land and mine?" Caada asked. His projection was weak and feeble. It was obvious that he would not last for many more days unless feeding improved.

"I do not know. It is something of metal, and it bars my land. I cannot cross it. It burns me when I touch it."

A quick twinge of excitement rushed along Caada's filament. The old Ul broke the connection instantly, but not before Kworn read the flash of hope that Kworn had kindled. There was no help in this quarter, and the wild greed of Varsi was so well known that there was no sense even trying that side.

A surge of hopelessness swept through him. Unless he could find some way to pass this barrier he was doomed.

He didn't want to pass into Emptiness. He had seen too many others go that way to want to follow them. For a moment he thought desperately of begging Caada and Varsi for permission to cross into their land for the short time that would be necessary to pass the barrier, but reason asserted itself. Such an act was certain to draw a flat refusal and, after all, he was the Ul Kworn and he had his pride. He would not beg when begging was useless.

And there was a bare possibility that he might survive if he closed his mantle tightly about him and waited until all the ranks had passed. He could then bring up the rear ... and, possibly, just possibly, there would be sufficient food left to enable him to reach the winter feeding grounds.

And it might still be possible to cross the disc. There was enough warmth in it to keep him active. By working all night he might be able to build a path of sand across its surface and thus keep his tissues from being seared by the metal. He would be technically violating the law by moving ahead of the others, but if he did not feed ahead, no harm would be done.

He moved closer to the barrier and began to pile sand against its base, sloping it to make a broad ramp to the top of the disc. The work was slow and the sand was slippery. The polished grains slipped away and the ramp crumbled time after time. But he worked on, piling up sand until it reached the top of the disc. He looked across the flat surface that stretched before him.

Fifty raads!

It might as well be fifty zets. He couldn't do it. Already his energy level was so low that he could hardly move, and to build a raad-wide path across this expanse of metal was a task beyond his strength. He drooped across the ramp, utterly exhausted. It was no use. What he ought to do was open his mantle to Emptiness.

He hadn't felt the communication filaments of Caada and Varsi touch him. He had been too busy, but now with Caada's burst of glee, and Varsi's cynical, "A noble decision, Ul Kworn. You should be commended," he realized that they knew everything.

His body rippled hopelessly. He was tired, too tired for anger. His energy was low. He contemplated Emptiness impassively. Sooner or later it came to all Folk. He had lived longer than most, and perhaps it was his time to go. He was finished. He accepted the fact with a cold fatalism that he never dreamed he possessed. Lying there on the sand, his mantle spread wide, he waited for the end to come.

It wouldn't come quickly, he thought. He was still far from the cellular disorganization that preceded extinction. He was merely exhausted, and in need of food to restore his energy.

With food he might still have an outside chance of building the path in time. But there was no food. He had gleaned his area completely before he had ever reached the roadblock.

Lying limp and relaxed on the ramp beside the barrier, he slowly became conscious that the metal wasn't dead. It was alive! Rhythmic vibrations passed through it and were transmitted to his body by the sand.

A wild hope stirred within him. If the metal were alive it might hear him if he tried to communicate. He concentrated his remaining reserves of energy, steeled himself against the pain and pressed a communication filament against the metal.

"Help me!" he projected desperately. "You're blocking my strip! I can't pass!"

Off to one side he sensed Varsi's laughter and on the other felt Caada's gloating greed.

"I cannot wake this metal," he thought hopelessly as he tried again, harder than before, ignoring the pain of his burning flesh.

Something clicked sharply within the metal, and the tempo of the sounds changed.

"It's waking!" Kworn thought wildly.

There was a creaking noise from above. A rod moved out from the cylinder and twisted into the ground in Varsi's territory, to the accompaniment of clicking, grinding noises. A square grid lifted from the top of the cylinder and began rotating. And Kworn shivered and jerked to the tremendous power of the words that flowed through him. They were words, but they had no meaning, waves of sound that hammered at his receptors in an unknown tongue he could not understand. The language of the Folk had changed since the days of the ancients, he thought despairingly.

And then, with a mantle-shattering roar, the cylinders jutting overhead spouted flame and smoke. Two silvery balls trailing thin, dark filaments shot out of the great cylinder and buried themselves in the sand behind him. The filaments lay motionless in the sand as Kworn, wrapped defensively in his mantle, rolled off the ramp to the ground below.

The silence that followed was so deep that it seemed like Emptiness had taken the entire land.

Slowly Kworn loosened his mantle. "In the name of my first ancestor," he murmured shakily, "what was that?" His senses were shocked and disorganized by the violence of the sound. It was worse even than the roar and scream of the samshin that occasionally blew from the south, carrying dust, lichens, feeders and even Folk who had been too slow or too foolish to hide from the fury of the wind.

Gingerly, Kworn inspected the damage to his mantle. It was minor. A tiny rip that could easily be repaired, a few grains of sand that could be extruded. He drew himself together to perform the repairs with the least possible loss of energy, and as he did, he was conscious of an emanation coming from the filaments that had been hurled from the cylinder.

Food!

And such food!

It was the distilled quintessence of a thousand purple feeders! It came to his senses in a shimmering wave of ecstasy so great that his mantle glowed a bright crimson. He stretched a pseudopod toward its source, and as he touched the filament his whole body quivered with anticipation. The barrier was blotted from his thoughts by an orgy of shuddering delight almost too great for flesh to endure. Waves of pleasure ran through his body as he swiftly extended to cover the filament. It could be a trap, he thought, but it made no difference. The demands of his depleted body and the sheer vacuole-constricting delight of this incredible foodstuff made a combination too potent for his will to resist, even if it had desired to do so. Waves of pleasure rippled through him as more of his absorptive surface contacted the filament. He snuggled against it, enfolding it completely, letting the peristaltic rushes sweep through him. He had never fed like this as long as he could recall. His energy levels swelled and pulsed as he sucked the last delight from the cord, and contemplated the further pleasure waiting for him in that other one lying scarcely twenty raads away.

Sensuously, he extended a pseudopod from his upper surface and probed for the other filament. He was filled to the top of his primary vacuole but the desire for more was stronger than ever—despite the fact that he knew the food in the other filament would bring him to critical level, would force him to reproduce. The thought amused him. As far back as he could remember, no member of the Folk had ever budded an offspring during the Time of Travel. It would be unheard of, something that would go down through the years in the annals of the Folk, and perhaps even cause a change in the Law.

The pseudopod probed, reached and stopped short of its goal. There was nothing around it but empty air.

Fear drove the slow orgasmic thoughts from his mind. Absorbed in gluttony, he hadn't noticed that the filament had tightened and was slowly drawing back into the cylinder from whence it came. And now it was too late! He was already over the rim of the metal disc.

Feverishly, he tried to disengage his absorptive surfaces from the filament and crawl down its length to safety, but he couldn't move. He was stuck to the dark cord by some strange adhesive that cemented his cells firmly to the cord. He could not break free.

The line moved steadily upward, dragging him inexorably toward a dark opening in the cylinder overhead. Panic filled him! Desperately he tried to loosen his trapped surfaces. His pseudopod lashed futilely in the air, searching with panic for something to grip, something to clutch that would stop this slow movement to the hell of pain that waited for him in the metal high overhead.

His searching flesh struck another's, and into his mind flooded the Ul Caada's terrified thought. The old one had reacted quicker than he, perhaps because he was poaching, but like himself he was attached and could not break free.

"Serves you right," Kworn projected grimly. "The thing was on my land. You had no right to feed upon it."

"Get me loose!" Caada screamed. His body flopped at the end of a thick mass of digestive tissue, dangling from the line, writhing and struggling in mindless terror. It was strange, Kworn thought, that fear should be so much stronger in the old than in the young.

"Cut loose, you fool," Kworn projected. "There isn't enough of you adhered to hurt if it were lost. A little body substance isn't worth your life. Hurry! You'll be too late if you don't. That metal is poisonous to our flesh."

"But it will be pain to cut my absorbing surface," Caada protested.

"It will be death if you don't."

"Then why don't you?"

"I can't," Kworn said hopelessly. "All my surface is stuck to the filament. I can't cut free." He was calm now, resigned to the inevitable. His greed had brought him to this. Perhaps it was a fitting punishment. But Caada need not die if he would show courage.

He rotated his eye to watch his struggling neighbor. Apparently Caada was going to take his advice. The tissue below the part of him stuck to the filament began to thin. His pseudopod broke contact. But his movements were slow and hesitant. Already his body mass was rising above the edge of the disc.

"Quick, you fool!" Kworn projected. "Another moment and you're dead!"

But Caada couldn't hear. Slowly his tissues separated as he reluctantly abandoned his absorptive surface. But he was already over the disc. The last cells pinched off and he fell, mantle flapping, full on the surface of the disc. For a moment he lay there quivering, and then his body was blotted from sight by a cloud of frozen steam, and his essence vanished screaming into Emptiness.

Kworn shuddered. It was a terrible way to die. But his own fate would be no better. He wrapped his mantle tightly around him as his leading parts vanished into the dark hole in the cylinder. In a moment he would be following Caada on the journey from which no member of the Folk had ever returned. His body disappeared into the hole.

—and was plunged into paradise!

His foreparts slipped into a warm, thick liquid that loosened the adhesive that bound him to the cord. As he slipped free, he slowly realized that he was not to die. He was bathed in liquid food! He was swimming in it! He was surrounded on all sides by incredible flavors so strange and delicious that his mind could not classify them! The filament had been good, but this—this was indescribable! He relaxed, his mantle spreading through the food, savoring, absorbing, digesting, metabolizing, excreting. His energy levels peaked. The nuclei of his germ plasm swelled, their chromosomes split, and a great bud formed and separated from his body. He had reproduced!

Through a deadening fog of somatic sensation, he realized dully that this was wrong, that the time wasn't right, that the space was limited, and that the natural reaction to abundant food supply was wrong. But for the moment he didn't care.

For thousands of seasons he had traveled the paths between equator and pole in a ceaseless hunt for food, growing and rejuvenating in good seasons, shrinking and aging in bad. He had been bound to the soil, a slave to the harsh demands of life and Nature. And now the routine was broken.

He luxuriated in his freedom. It must have been like this in the old days, when the waters were plentiful and things grew in them that could be eaten, and the Folk had time to dream young dreams and think young thoughts, and build their thoughts and dreams into the gleaming realities of cities and machines. Those were the days when the mind went above the soil into the air and beyond it to the moons, the sun and the evening stars.

But that was long ago.

He lay quietly, conscious of the change within him as his cells multiplied to replace those he had lost, and his body grew in weight and size. He was rejuvenated. The cells of his growing body, stimulated by the abundance of food, released memories he had forgotten he had ever possessed. His past ran in direct cellular continuity to the dawn of his race, and in him was every memory he had experienced since the beginning. Some were weak, others were stronger, but all were there awaiting an effort of recall. All that was required was enough stimulation to bring them out of hiding.

And for the first time in millennia the stimulus was available. The stimulus was growth, the rapid growth that only an abundant food supply could give, the sort of growth that the shrunken environment outside could not supply. With sudden clarity he saw how the Folk had shrunk in mind and body as they slowly adapted to the ever-increasing rigor of life. The rushing torrent of memory and sensation that swept through him gave him a new awareness of what he had been once and what he had become. His eye was lifted from the dirt and lichens.

What he saw filled him with pity and contempt. Pity for what the Folk had become; contempt for their failure to recognize it. Yet he had been no better than the others. It was only through the accident of this artefact that he had learned. The Folk couldn't know what the slow dwindling of their food supply had done to them. Over the millennia they had adapted, changing to fit the changing conditions, surviving only because they were more intelligent and more tenacious than the other forms of life that had become extinct. A thousand thousand seasons had passed since the great war that had devastated the world. A million years of slow adaptation to the barren waste that had been formed when the ultimate products of Folk technology were loosed on their creators, had created a race tied to a subsistence level of existence, incapable of thinking beyond the basic necessities of life.

The Ul Kworn sighed. It would be better if he would not remember so much. But he could suppress neither the knowledge nor the memories. They crowded in upon him, stimulated by the food in which he floated.

Beside him, his offspring was growing. A bud always grew rapidly in a favorable environment, and this one was ideal. Soon it would be as large as himself. Yet it would never develop beyond an infant. It could not mature without a transfer of germ plasm from other infants of the Folk. And there were no infants.

It would grow and keep on growing because there would be no check of maturity upon its cells. It would remain a partly sentient lump of flesh that would never be complete. And in time it would be dangerous. When it had depleted the food supply it would turn on him in mindless hunger. It wouldn't realize that the Ul Kworn was its father, or if it did, it wouldn't care. An infant is ultimately selfish, and its desires are the most important thing in its restricted universe.

Kworn considered his situation dispassionately.

It was obvious that he must escape from this trap before his offspring destroyed him. Yet he could think of no way to avoid the poison metal. He recognized it now, the element with the twelve protons in its nucleus, a light metal seldom used by the Folk even in the days of their greatness because of its ability to rapidly oxidize and its propensity to burst into brilliant flame when heated. With sudden shock he realized that the artefact was nothing less than a gigantic torch!

Why had it been built like this? What was its function? Where had it come from? Why hadn't it spoke since it had released that flood of unintelligible gibberish before it had drawn him inside? Ever since he had entered this food tank it had been quiet except for a clicking, chattering whir that came from somewhere above him. He had the odd impression that it was storing information about him and the way he reacted in the tank.

And then, abruptly, it broke into voice. Cryptic words poured from it, piercing him with tiny knives of sound. The intensity and rapidity of the projections shocked him, left him quivering and shaking when they stopped as abruptly as they had begun.

In the quiet that followed, Kworn tried to recall the sequence of the noise. The words were like nothing he had ever heard. They were not the language of the Folk either past or present. And they had a flow and sequence that was not organic. They were mechanical, the product of a metal intelligence that recorded and spoke but did not think. The Folk had machines like that once.

How had it begun? There had been a faint preliminary, an almost soundless voice speaking a single word. Perhaps if he projected it, it would trigger a response. Pitching his voice in the same key and intensity he projected the word as best he could remember it.

And the voice began again.

Kworn quivered with excitement. Something outside the artefact was forcing it to speak. He was certain of it. As certain as he was that the artefact was recording himself and his offspring. But who—or what—was receiving the record? And why?

This could be a fascinating speculation, Kworn thought. But there would be time enough for that later. His immediate need was to get out. Already the food supply was running low, and his offspring was becoming enormous. He'd have to leave soon if he was ever going to. And he'd have to do something about his own growth. Already it was reaching dangerous levels. He was on the ragged edge of another reproduction, and he couldn't afford it.

Regretfully, he began moving the cornified cells of his mantle and his under layer toward his inner surfaces, arranging them in a protective layer around his germ plasm and absorptive cells. There would be enough surface absorption to take care of his maintenance needs, and his body could retain its peak of cellular energy. Yet the desire to feed and bud was almost overpowering. His body screamed at him for denying it the right that food would give it, but Kworn resisted the demands of his flesh until the frantic cellular urges passed.

Beside him his offspring pulsed with physical sensation. Kworn envied it even as he pitied it. The poor mindless thing could be used as a means to the end of his escape, but it was useless for anything else. It was far too large, and far too stupid, to survive in the outside world. Kworn extruded a net of hairlike pseudopods and swept the tank in which they lay. It was featureless, save for a hole where the filament had not completely withdrawn when it had pulled him into this place. A few places in the wall had a different texture than the others, probably the sense organs of the recorder. He rippled with satisfaction. There was a grille of poison metal in the top of the tank through which flowed a steady current of warm air. It would be pleasant to investigate this further, Kworn thought, but there was no time. His offspring had seen to that.

He placed his eye on a thin pseudopod and thrust it through the hole in the wall of the tank. It was still night outside, but a faint line of brightness along the horizon indicated the coming of dawn. The artefact glittered icily beneath him, and he had a feeling of giddiness as he looked down the vertiginous drop to the disc below. The dark blotch of Caada's burned body was almost invisible against the faintly gleaming loom of the still-warm disc. Kworn shuddered. Caada hadn't deserved a death like that. Kworn looked down, estimating the chances with his new intelligence, and then slapped a thick communication fibril against his offspring's quivering flesh and hurled a projection at its recoiling mass.

Considering the fact that its cells were direct derivations of his own, Kworn thought grimly, it was surprising how hard it was to establish control. The youngster had developed a surprising amount of individuality in its few xals of free existence. He felt a surge of thankfulness to the old Ul Kworn as the youngster yielded to his firm projection. His precursor had always sought compliant germ plasm to produce what he had called "discipline and order." It was, in fact, weakness. It was detrimental to survival. But right now that weakness was essential.

Under the probing lash of his projection the infant extruded a thick mass of tissue that met and interlocked with a similar mass of his own. As soon as the contact firmed, Kworn began flowing toward his eye, which was still in the half-open hole in the side of the tank.

The outside cold struck his sense centers with spicules of ice as he flowed to the outside, clinging to his offspring's gradually extending pseudopod. Slowly he dropped below the cylinder. The infant was frantic. It disliked the cold and struggled to break free, but Kworn clung limpetlike to his offspring's flesh as it twisted and writhed in an effort to return to the warmth and comfort into which it was born.

"Let go!" his offspring screamed. "I don't like this place."

"In a moment," Kworn said as he turned the vague writhings into a swinging pendulum motion. "Help me move back and forth."

"I can't. I'm cold. I hurt. Let me go!"

"Help me," Kworn ordered grimly, "or hang out here and freeze."

His offspring shuddered and twitched. The momentum of the swing increased. Kworn tightened his grip.

"You promised to let go!" his offspring wailed. "You prom—"

The infant's projection was cut off as Kworn loosed himself at the upward arc of the swing, spread his mantle and plummeted toward the ground. Fear swept through him as his body curved through the thin air, missing the edge of the disc and landing on the ground with a sense-jarring thud. Behind and above him up against the cylinder, the thick tendril of his offspring's flesh withdrew quickly from sight. For a moment the Ul Kworn's gaze remained riveted on the row of odd markings on the metal surface, and then he turned his attention to life.

There was no reason to waste the pain of regret upon that half sentient mass of tissue that was his offspring. The stupid flesh of his flesh would remain happy in the darkness with the dwindling food until its flesh grew great enough to touch the poison metal in the ceiling of the tank.

And then—

With a harsh projection of horror, the Ul Kworn moved, circling the artefact on Caada's vacated strip. And as he moved he concentrated energy into his high-level communication organs, and projected a warning of danger.

"Move!" he screamed. "Move forward for your lives!"

The line rippled. Reddish mantles unfolded as the Folk reacted. The nearest, shocked from estivation, were in motion even before they came to full awareness. Alarms like this weren't given without reason.

Varsi's reaction, Kworn noted, was faster than any of his fellows. The young Ul had some favorable self-preservation characteristics. He'd have to consider sharing some germ plasm with him at the next reproduction season, after all.

In a giant arc, the Folk pressed forward under the white glow of emerging dawn. Behind them the artefact began to project again in its strange tongue. But in mid-cry it stopped abruptly. And from it came a wail of mindless agony that tore at Kworn's mind with regret more bitter because nothing could be done about it.

His offspring had touched the poison metal.

Kworn turned his eye backwards. The artefact was shaking on its broad base from the violence of his offspring's tortured writhings. As he watched a brilliant burst of light flared from its top. Heat swept across the land, searing the lichens and a scattered few of the Folk too slow to escape. The giant structure burned with a light more brilliant than the sun and left behind a great cloud of white vapor that hung on the air like the menacing cloud of a samshin. Beneath the cloud the land was bare save for a few twisted pieces of smoking metal.

The roadblock was gone.

Kworn moved slowly forward, gleaning Caada's strip and half of his own which he shared with Varsi.

He would need that young Ul in the future. It was well to place him under an obligation. The new thoughts and old memories weren't dying. They remained, and were focused upon the idea of living better than at this subsistence level. It should be possible to grow lichens, and breed a more prolific type of lichen feeder. Water channeled from the canals would stimulate lichen growth a thousand-fold. And with a more abundant food supply, perhaps some of the Folk could be stimulated to think and apply ancient buried skills to circumvent Nature.

It was theoretically possible. The new breed would have to be like Varsi, tough, driving and selfishly independent. In time they might inherit the world. Civilization could arise again. It was not impossible.

His thoughts turned briefly back to the artefact. It still bothered him. He still knew far too little about it. It was a fascinating speculation to dream of what it might have been. At any rate, one thing was sure. It was not a structure of his race. If nothing else, those cabalistic markings on the side of the cylinder were utterly alien.

Thoughtfully he traced them in the sand. What did they mean?

performances and research. They may be modified and printed and given
away--you may do practically ANYTHING in the United States with eBooks

trademark license, especially commercial redistribution.

1.F.

1.F.1. Project Gutenberg volunteers and employees expend considerable
effort to identify, do copyright research on, transcribe and proofread
works not protected by U.S. copyright law in creating the Project

Section 2. Information about the Mission of Project Gutenberg-tm

Project Gutenberg-tm is synonymous with the free distribution of
electronic works in formats readable by the widest variety of
computers including obsolete, old, middle-aged and new computers. It
exists because of the efforts of hundreds of volunteers and donations
from people in all walks of life.

Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg-tm's
goals and ensuring that the Project Gutenberg-tm collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg-tm and future
generations. To learn more about the Project Gutenberg Literary
Archive Foundation and how your efforts and donations can help, see
Sections 3 and 4 and the Foundation information page at
www.gutenberg.org Section 3. Information about the Project Gutenberg
Literary Archive Foundation

501(c)(3) educational corporation organized under the laws of the
state of Mississippi and granted tax exempt status by the Internal
Revenue Service. The Foundation's EIN or federal tax identification
number is 64-6221541. Contributions to the Project Gutenberg Literary
Archive Foundation are tax deductible to the full extent permitted by
U.S. federal laws and your state's laws.

Section 4. Information about Donations to the Project Gutenberg
Literary Archive Foundation

Project Gutenberg-tm depends upon and cannot survive without wide
spread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine readable form accessible by the widest
array of equipment including outdated equipment. Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.

The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements. We do not solicit donations in locations
where we have not received written confirmation of compliance. To SEND
DONATIONS or determine the status of compliance for any particular
state visit www.gutenberg.org/donate

While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.

International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg Web pages for current donation
methods and addresses. Donations are accepted in a number of other
ways including checks, online payments and credit card donations. To
donate, please visit: www.gutenberg.org/donate

Section 5. General Information About Project Gutenberg-tm electronic works.

Professor Michael S. Hart was the originator of the Project
Gutenberg-tm concept of a library of electronic works that could be
freely shared with anyone. For forty years, he produced and
distributed Project Gutenberg-tm eBooks with only a loose network of
volunteer support.

Project Gutenberg-tm eBooks are often created from several printed
editions, all of which are confirmed as not protected by copyright in
the U.S. unless a copyright notice is included. Thus, we do not
necessarily keep eBooks in compliance with any particular paper
edition.

Most people start at our Web site which has the main PG search
facility: www.gutenberg.org

This Web site includes information about Project Gutenberg-tm,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
