Had she been playing with him? Had she been filling the gullible foreigner with a mess of lies for amusement's sake? Such things had been known to happen on every world and in every time. An air of transparent honesty was no guide either; in fact, successful Wetellers would deliberately cultivate just such an air.

  So could there really be six-meter trees Upperside? Without thinking much about it, he moved in the direction of the highest dome on the horizon. He swung his arms in an attempt to warm himself. And his feet were getting cold.

  Clowzia hadn't pointed. She might have, to give him a hint of the direction of the trees, but she didn't. Why didn't she? To be sure, she had been called away.

  The domes were broad rather than high, which was a good thing, since otherwise the going would have been considerably more difficult. On the other hand, the gentle grade meant trudging a distance before he could top a dome and look down the other side.

  Eventually, he could see the other side of the dome he had climbed. He looked back to make sure he could still see the meteorologists and their instruments. They were a good way off, in a distant valley, but he could see them clearly enough. Good.

  He saw no copse, no trees, but there was a depression that snaked about between two domes. Along each side of that crease, the soil was thicker and there were occasional green smears of what might be moss. If he followed the crease and if it got low enough and the soil was thick enough, there might be trees.

  He looked back, trying to fix landmarks in his mind, but there were just the rise and fall of domes. It made him hesitate and Dors's warning against his being lost, which had seemed a rather unnecessary piece of advice then, made more sense now. Still, it seemed clear to him that the crease was a kind of road. If he followed it for some distance, he only had to turn about and follow it back to return to this spot.

  He strode off purposefully, following the rounded crease downward. There was a soft rumbling noise above, but he didn't give it any thought. He had made up his mind that he wanted to see trees and that was all that occupied him at the moment.

  The moss grew thicker and spread out like a carpet and here and there grassy tufts had sprung up. Despite the desolation Upperside, the moss was bright green and it occurred to Seldon that on a cloudy, overcast planet there was likely to be considerable rain.

  The crease continued to curve and there, just above another dome, was a dark smudge against the gray sky and he knew he had found the trees.

  Then, as though his mind, having been liberated by the sight of those trees, could turn to other things, Seldon took note of the rumble he had heard before and had, without thinking, dismissed as the sound of machinery. Now he considered that possibility: Was it, indeed, the sound of machinery?

  Why not? He was standing on one of the myriad domes that covered hundreds of millions of square kilometers of the worldcity. There must be machinery of all kinds hidden under those domes-ventilation motors, for one thing. Maybe it could be heard, where and when all the other sounds of the world-city were absent.

  Except that it did not seem to come from the ground. He looked up at the dreary featureless sky. Nothing.

  He continued to scan the sky, vertical creases appearing between his eyes and then, far off

  It was a small dark spot, showing up against the gray. And whatever it was it seemed to be moving about as though getting its bearings before it was obscured by the clouds again.

  Then, without knowing why, he thought, They're after me.

  And almost before he could work out a line of action, he had taken one. He ran desperately along the crease toward the trees and then, to reach them more quickly, he turned left and hurtled up and over a low dome, treading through brown and dying fernlike overgrowth, including thorny sprigs with bright red berries.

  24.

  Seldon panted, facing a tree, holding it closely, embracing it. He watched for the flying object to make its appearance again so that he could back about the tree and hide on the far side, like a squirrel.

  The tree was cold, its bark was rough, it gave no comfort-but it offered cover. Of course, that might be insufficient, if he was being searched for with a heat-seeker, but, on the other hand, the cold trunk of a tree might blur even that.

  Below him was hard-pecked soil. Even in this moment of hiding, of attempting to see his pursuer while remaining unseen, he could not help wondering hhowow thick the soil might be, how long it had taken to accumulate, many domes in the warmer areas of Trantor tarried forests on their back, and whether the trees were always confined to the creases between domes, leaving the higher regions to moss, grass, and underbrush.

  He sew it again. It was not a hypership, nor even an ordinary airjet. It was a jet-down. He could see the faint glow of the ion trails corning out at the vertices of a hexagon, neutralizing the gravitational pull and allowing the wings to keep it aloft like a large soaring bird. It was a vehicle that could hover and explore a planetary terrain.

  It was only the clouds than had saved him. Even if they were using heat-seekers, that would only indicate there were people below. The jetdown would have m make a tentative dive below the banked ceiling before it could hope to know how many human beings there were and whether any of them might be the particular person the patties aboard were seeking.

  The jet-down was closer now, but it couldn't hide from him either. The rumble of the engine gave it away and they couldn't rum that off, not as long as they wished to continue their search. Seldon knew the jetdowns, for on Helicon or on any undomed world with skies that cleared now and then, they were common, with many in private hands.

  Of what possible use would jet-downs be on Trantor, with all the human life of the world under domes, with low cloud ceilings all but perpetual-except for a few government vehicles designed for just this purpose, chat of picking up a wanted person who had been lured above the domes?

  Why not? Government forces could nor enter the grounds of the University, but perhaps Seldon was no longer on the grounds. He was on top of the domes which might be outside the jurisdiction of any local government. An Imperial vehicle might have every right to land on any part of the dome and question or remove any person found upon is Hummin had not warned him of this, but perhaps he had merely not thought of doing so.

  The jet-down was even closer now, nosing about like a blind beast sniffing out its prey. Would it occur to them to search this group of trees? Would they land and send out an armed soldier or two to beat through the copse?

  And if so, what could he do? He was unarmed and all his quicktwist agility would be useless against the agonizing pain of a neuronic whip.

  It was not attempting to land. Either they missed the significance of the trees

  Or--

  A new thought suddenly hit him. What if this wasn't a pursuit vessel at all? What if it was part of the meteorological testing? Surely, meteorologists would want to test the upper reaches of the atmosphere.

  Was he a fool to hide from it?

  The sky was getting darker. The clouds were getting thicker or, much more likely, night was falling.

  And it was getting colder and would get colder still. Was he going to stay out here freezing because a perfectly harmless jetdown had made an appearance and had activated a sense of paranoia that he had never felt before? He had a strong impulse to leave the copse and get back to the meteorological station.

  After all, how would the man Hummin feared so muchDemercel-know that Seldon would, at this particular time, be Upperside and ready to be taken?

  For a moment, that seemed conclusive and, shivering with the cold, he moved out from behind the tree.

  And then he scurried back as the vessel reappeared even closer than before. He hadn't seen it do anything that would seem to be meteorological. It did nothing that might be considered sampling, measuring, or testing. Would he see such things if they took place? He did not know the precise sort of instruments the jet-down carried or how they worked. If they were doing meteorological work, he might
not be able to tell. -Still, could he take the chance of coming into the open?

  After all, what if Demerzel did know of his presence Upperside, simply because an agent of his, working in the University, knew about it and had reported the matter. Listing Randa, that cheerful, smiling little Easterner, had suggested he go Upperside. He had suggested it quite forcefully and the subject had not arisen naturally out of the conversation; at least, not naturally enough. Was it possible that he was a government agent and had alerted Demerzel somehow?

  Then there was Leggen, who had given him the sweater. The sweater was useful, but why hadn't Leggen told him he would need one earlier so he could get his own? Was there something special about the one he was wearing? It was uniformly purple, while all the others' indulged in the Trantorian fashion of bright patterns. Anyone looking down from a height would see a moving dull blotch in among others that were bright and know immediately whom they wanted.

  And Clowzia? She was supposedly Upperside to learn meteorology and help the meteorologists. How was it possible that she could come to him, talk to him at ease, and quietly walk him away from the others and isolate him so that he could easily be picked up?

  For that matter, what about Dors Venabili? She knew he was going Upperside. She did not stop it. She might have gone with him, but she was conveniently busy.

  It was a conspiracy. Surely, it was a conspiracy.

  He had convinced himself now and there was no further thought of getting out from the shelter of the trees. (His feet felt like lumps of ice and stamping them against the ground seemed to do no good.) Would the jet-down never leave?

  And even as he thought that, the pitch of the engine's rumble heightened and the jet-down rose into the clouds and faded away.

  Seldon listened eagerly, alett to the smallest sound, making sure it was finally gone. And then, even after he was sure it was gone, he wondered if that was just a device to flush him out of hiding. He remained where he was while the minutes slowly crawled on and night continued to fall.

  And finally, when he felt that the true alternative to taking the chance of coming out in the open was that of freezing into insensibility, he stepped out and moved cautiously beyond the shelter of the trees.

  It was dusky twilight, after all. They couldn't detect him except by a hear-seeker, but, if so, he would hear die jet-down return. He waited just beyond the trees, counting to himself, ready to hide in the copse again at the smallest sound-though what good that would do him once he was spotted, he couldn't imagine.

  Seldon looked about. If he could find the meteorologists, they would surely have artificial light, but except for that, there would be nothing.

  He could still just make out his surroundings, but in a matter of a quarter of an hour, half an hour at the outside, he would not. With no lights and a cloudy sky above, it would be dark-completely dark.

  Desperate at the prospect of being enveloped in total darkness, Seldon realized that he would have to find his way back to the crease that had brought him there as quickly as possible and retrace his steps. Folding his arms tightly around himself for warmth, he set off in what he thought was the direction of the crease between the domes.

  There might, of course, be more than one crease leading away from the copse, but he dimly made out some of the sprigs of berries he had seen coming in, which now looked almost black rather than bright red. He could not delay. He had to assume he was right. He moved up the crease as fast as he might, guided by failing sight and by the vegetation underfoot.

  But he couldn't stay in the crease forever. He had come over what had seemed to him to be the tallest dome in sight and had found a crease that cut at right angles across his line of approach. By his reckoning, he should now turn right, then sharp left, and that would put him on the path toward the meteorologists' dome.

  Seldon made the left turn and, lifting his head, he could just make out the curve of a dome against the fractionally lighter sky. That had to be it!

  Or was that only wishful thinking?

  He had no choice but to assume it wasn't. Keeping his eye on the peak so that he could move in a reasonably straight line, he headed for it as quickly as he could. As he got closer, he could make out the line of dome against sky with less and less certainty as it loomed larger and larger. Soon, if he was correct, he would be going up a gentle slope and when that slope became level he would be able to look down the other side and see the lights of the meteorologists.

  In the inky dark, he could not tell what lay in his path. Wishing there were at least a few sorts to shed some light, he wondered if this was how it felt to be blind. He waved his arms before him as if they were antennae.

  It was growing colder by the minute and he paused occasionally to blow on his hands and hold them under his armpits. He wished earnestly he could do the same for his feet. By now, he thought, if it started to precipitate, it would be snow-or, worse yet, sleet.

  On . . . on. There was nothing else to do.

  Eventually, it seemed to him that he was moving downward. That was either wishful thinking or he had topped the dome.

  He stopped. If he had topped the dome, he should be able to see the artificial light of the meteorological station. He would see the lights carried by the meteorologists themselves, sparkling or dancing like fireflies.

  Seldon closed his eyes as though to accustom them to dark and then try again, but that was a foolish effort. It was no darker with his eyes closed than with them open and when he opened them it was no lighter than when he had had them closed.

  Possibly Leggen and the others were gone, had taken their lights with them and had turned off any lights on the instruments. Or possibly Seldon had climbed the wrong dome. Or he had followed a curved path along the dome so that he was now facing in the wrong direction. Or he had followed the wrong crease and had moved away from the copse in the wrong direction altogether.

  What should he do?

  If he was facing the wrong direction, there was a chance that light would be visible right or left-and it wasn't. If he had followed the wrong crease, there was no possible way he could return to the copse and locate a different crease.

  His only chance lay in the assumption that he was facing the right direction and that the meteorological station was more or less directly ahead of him, but that the meteorologists had gone and had left it in darkness.

  Move forward, then. The chances of success might be small, but it was the only chance he had.

  He estimated that it had taken him half an hour to move from the meteorological station to the top of the dome, having gone partway with Clowzia and sauntering with her rather than striding. He was moving at little better than a saunter now in the daunting darkness.

  Seldon continued to slog forward. It would have been nice to know the time and he had a timeband, of course, but in the dark

  He stopped. He wore a Trantorian timeband, which gave Galactic Standard time (as all timebands did) and which also gave Trantorian local time. Timebands were usually visible in the dark, phosphorescing so that one could tell time in the quiet dark of a bedchamber. A Heliconian timeband certainly would; why not a Trantorian one?

  He looked at his timeband with reluctant apprehension and touched the contact that would draw upon the power source for light. The timeband gleamed feebly and told him the time was 1847. For it to be nighttime already, Seldon knew that it must be the winter season. -How far past the solstice was it? What was the degree of axial tipping? How long was the year? How far from the equator was he at this moment? There was no hint of an answer to any of these things, but what counted was that the spark of light was visible.

  He was not blind! Somehow the feeble glow of his timeband gave him renewed hope.

  His spirits rose. He would move on in the direction he was going. He would move for half an hour. If he encountered nothing, he would move on five minutes more-no further-just five minutes. If he still encountered nothing, he would stop and think. That, however, would be thirty-five minutes
from now. Till then, he would concentrate only on walking and on willing himself to feel warmer (He wiggled his toes, vigorously. He could still feel them.)

  Seldon trudged onward and the half hour passed. He paused, then hesitantly, he moved on for five more minutes.

  Now he had to decide. There was nothing. He might be nowhere, far removed from any opening into the dome. He might, on the other hand, be standing three meters to the left-or right-or short-of the meteorological station. He might be two arms' lengths from the opening into the dome, which would not, however, be open.

  Now what?

  Was there any point in shouting? He was enveloped by utter silence but for the whistling of the wind. If there were birds, beasts, or insects in among the vegetation on the domes, they were not here during this season or at this time of night or at this particular place. The wind continued to chill him.

  Perhaps he should have been shouting all due way. The sound might have carried a good distance in the cold air. But would there have been anyone to hear him?

  Would they hear him inside the dome? Were there instruments to detect sound or movement from above? Might there not be sentinels just inside?

  That seemed ridiculous. They would have heard his footsteps, wouldn't they?

  Still-

  He called out. "Help! Help! Can someone hear me?"

  His cry was strangled, half-embarassed. It seemed silly shouting into vast black nothingness.

  But then, he felt it was even sillier to hesitate in such a situation as this. Panic was welling up in him. He took in a deep, cold breath and screamed for as long as he could. Another breath and another scream, changing pitch. And another.

  Seldon paused, breathless, turning his head every which way, even though there was nothing to see. He could not even detect an echo. There was nothing left to do but wait for the dawn. But how long was the night at this season of the year? And how cold would it get?

  He felt a tiny cold touch sting his face. After a while, another.

  It was sleeting invisibly in the pitch blackness. And there was no way to find shelter.
