Sim leaned forward, forgetting his crippled foot.

  A huge man appeared in a cave mouth on the third level.

  ‘Come down,’ urged Sim. ‘Come down, fat one, and kill me.’

  The man scowled seriously at his opponent a moment, then lumbered slowly down the path, his hands empty of any weapons. Immediately every cave above clustered with heads. An audience for this drama.

  The man approached Sim. ‘We will fight by the rules, if you know them.’

  ‘I’ll learn as we go,’ replied Sim.

  This pleased the man and he looked at Sim warily, but not unkindly. ‘This much I will tell you,’ offered the man generously. ‘If you die, I will give your mate shelter and she will live as she pleases, because she is the wife of a good man.’

  Sim nodded swiftly. ‘I am ready,’ he said.

  ‘The rules are simple. We do not touch each other, save with stones. The stones and the sun will do either of us in. Now is the time—’

  VIII

  A tip of the sun showed on the horizon. ‘My name is Nhoj,’ said Sim’s enemy, casually taking up a handful of pebbles and stones, weighing them. Sim did likewise. He was hungry. He had not eaten for many minutes. Hunger was the curse of this planet’s peoples—a perpetual demanding of empty stomachs for more, more food. His blood flushed weakly, shot tinglingly through veins in jolting throbs of heat and pressure, his rib cage shoved out, went in, shoved out again, impatiently.

  ‘Now!’ roared the three hundred watchers from the cliffs. ‘Now!’ they clamored, the men and women and children balanced, in turmoil on the ledges. ‘Now! Begin!’

  As if at a cue, the sun arose. It smote them a blow as with a flat, sizzling stone. The two men staggered under the molten impact, sweat broke from their naked thighs and loins, under their arms and on their faces was a glaze like fine glass.

  Nhoj shifted his huge weight and looked at the sun as if in no hurry to fight. Then, silently, with no warning, he snapped out a pebble with a startling trigger-flick of thumb and forefinger. It caught Sim flat on the cheek, staggered him back, so that a rocket of unbearable pain climbed up his crippled foot and burst into nervous explosion at the pit of his stomach. He tasted blood from his bleeding cheek.

  Nhoj moved serenely. Three more flicks of his magical hands and three tiny, seemingly harmless bits of stone flew like whistling birds. Each of them found a target, slammed it. The nerve centers of Sim’s body! One hit his stomach so that ten hours’ eating almost slid up his throat. A second got his forehead, a third his neck. He collapsed to the boiling sand. His knee made a wrenching sound on the hard earth. His face was colorless and his eyes, squeezed tight, were pushing tears out from the hot, quivering lids. But even as he had fallen he had let loose, with wild force, his handful of stones!

  The stones purred in the air. One of them, and only one, struck Nhoj. Upon the left eyeball. Nhoj moaned and laid his hands in the next instant to his shattered eye.

  Sim choked out a bitter, sighing laugh. This much triumph he had. The eye of his opponent. It would give him…Time, Oh, Gods, he thought, his stomach retching sickly, fighting for breath, this is a world of Time. Give me a little more, just a trifle!

  Nhoj, one-eyed, weaving with pain, pelted the writhing body of Sim, but his aim was off now, the stones flew to one side or if they struck at all they were weak and spent and lifeless.

  Sim forced himself half erect. From the corners of his eyes he saw Lyte, waiting, staring at him, her lips breathing words of encouragement and hope. He was bathed in sweat, as if a rain spray had showered him down.

  The sun was now fully over the horizon. You could smell it. Stones glinted like mirrors, the sand began to roil and bubble. Illusions sprang up everywhere in the valley. Instead of one warrior Nhoj he was confronted by a dozen, each in an upright position, preparing to launch another missile. A dozen irregular warriors who shimmered in the golden menace of day, like bronze gongs smitten, quivered in one vision!

  Sim was breathing desperately. His nostrils flared and sucked and his mouth drank thirstily of flame instead of oxygen. His lungs took fire like silk torches and his body was consumed. The sweat spilled from his pores to be instantly evaporated. He felt himself shriveling, shriveling in on himself, he imagined himself looking like his father, old, sunken, slight, withered! Where was the sand? Could he move? Yes. The world wriggled under him, but now he was on his feet.

  There would be no more fighting.

  A murmur from the cliff told this. The sunburnt faces of the high audience gaped and jeered and shouted encouragement to their warrior. ‘Stand straight, Nhoj, save your strength now! Stand tall and perspire!’ they urged him. And Nhoj stood, swaying lightly, swaying slowly, a pendulum in an incandescent fiery breath from the skyline. ‘Don’t move, Nhoj, save your heart, save your power!’

  ‘The test, the test!’ said the people on the heights. ‘The test of the sun.’

  And this was the worst part of the fight. Sim squinted painfully at the distorted illusion of cliff. He thought he saw his parents: father with his defeated face, his green eyes burning, mother with her hair blowing like a cloud of gray smoke in the fire wind. He must get up to them, live for and with them!

  Behind him, Sim heard Lyte whimper softly. There was a whisper of flesh against sand. She had fallen. He did not dare turn. The strength of turning would bring him thundering down in pain and darkness.

  His knees bent. If I fall, he thought, I’ll lie here and become ashes. Where was Nhoj? Nhoj was there, a few yards from him, standing bent, slick with perspiration, looking as if he were being hit over the spine with great hammers of destruction.

  Fall, Nhoj! Fall! thought Sim, Fall, fall! Fall so I can take your place!

  But Nhoj did not fall. One by one the pebbles in his half-loose left hand plummeted to the broiling sands and Nhoj’s lips peeled back, the saliva burned away from his lips and his eyes glazed. But he did not fall. The will to live was strong in him. He hung as if by a wire.

  Sim fell to one knee!

  ‘Ahh!’ wailed the knowing voices from the cliff. They were watching death. Sim jerked his head up, smiling mechanically, foolishly, as if caught in the act of doing something silly. ‘No, no,’ he insisted drowsily, and got back up again. There was so much pain he was all one ringing numbness. A whirring, buzzing, frying sound filled the land. High up, an avalanche came down like a curtain on a drama, making no noise. Everything was quiet except for a steady humming. He saw fifty images of Nhoj now, dressed in armors of sweat, eyes puffed with torture, cheeks sunken, lips peeled back like the rind of a drying fruit. But the wire still held him.

  ‘Now,’ muttered Sim, sluggishly, with a thick, baked tongue between his blazing teeth. ‘Now I’ll fall and lie and dream.’ He said it with slow, thoughtful pleasure. He planned it. He knew how it must be done. He would do it accurately. He lifted his head to see if the audience was watching.

  They were gone!

  The sun had driven them back in. All save one or two brave ones. Sim laughed drunkenly and watched the sweat gather on his dead hands, hesitate, drop off, plunge down toward sand and turn to steam halfway there.

  Nhoj fell.

  The wire was cut. Nhoj fell flat upon his stomach, a gout of blood kicked from his mouth. His eyes rolled back into a white, senseless insanity.

  Nhoj fell. So did his fifty duplicate illusions.

  All across the valley the winds sang and moaned and Sim saw a blue lake with a blue river feeding it and low white houses near the river with people going and coming in the houses and among the tall green trees. Trees taller than seven men, beside the river mirage.

  ‘Now,’ explained Sim to himself at last, ‘now I can fall. Right—into—that—lake.’

  He fell forward.

  He was shocked when he felt the hands eagerly stop him in mid-plunge, lift him, hurry him off, high in the hungry air, like a torch held and waved, ablaze.

  How strange is death, he thought, and blackness took him.

  He awakened to the flow of cool water on his cheeks.

  He opened his eyes fearfully. Lyte held his head upon her lap, her fingers were moving food to his mouth. He was tremendously hungry and tired, but fear squeezed both of these things away. He struggled upward, seeing the strange cave contours overhead.

  ‘What time is it?’ he demanded.

  ‘The same day as the contest. Be quiet,’ she said.

  ‘The same day!’

  She nodded amusedly. ‘You’ve lost nothing of your life. This is Nhoj’s cave. We are inside the black cliff. We will live three extra days. Satisfied? Lie down.’

  ‘Nhoj is dead?’ He fell back, panting, his heart slamming his ribs. He relaxed slowly. ‘I won. I won,’ he breathed.

  ‘Nhoj is dead. So were we, almost. They carried us in from outside only in time.’

  He ate ravenously. ‘We have no time to waste. We must get strong. My leg—’ He looked at it, tested it. There was a swath of long yellow grasses around it and the ache had died away. Even as he watched, the terrific pulsings of his body went to work and cured away the impurities under the bandages. It has to be strong by sunset, he thought. It has to be.

  He got up and limped around the cave like a captured animal. He felt Lyte’s eyes upon him. He could not meet her gaze. Finally, helplessly, he turned.

  She interrupted him. ‘You want to go on to the ship?’ she asked, softly. ‘Tonight? When the sun goes down?’

  He took a breath, exhaled it. ‘Yes.’

  ‘You couldn’t possibly wait until morning?’

  ‘No.’

  ‘Then I’ll go with you.’

  ‘No!’

  ‘If I lag behind, let me. There’s nothing here for me.’

  They stared at each other a long while. He shrugged wearily.

  ‘All right,’ he said, at last, ‘I couldn’t stop you, I know that. We’ll go together.’

  IX

  They waited in the mouth of their new cave. The sun set. The stones cooled so that one could walk on them. It was almost time for the leaping out and the running toward the distant, glittering metal seed that lay on the far mountain.

  Soon would come the rains. And Sim thought back over all the times he had watched the rains thicken into creeks, into rivers that cut new beds each night. One night there would be a river running north, the next a river running northeast, the third night a river running due west. The valley was continually cut and scarred by the torrents. Earthquakes and avalanches filled the old beds. New ones were the order of the day. It was this idea of the river and the directions of the river that he had turned over in his head for many hours. It might possibly—Well, he would wait and see.

  He noticed how living in this new cliff had slowed his pulse, slowed everything. A mineral result, protection against the solar radiations. Life was still swift, but not as swift as before.

  ‘Now, Sim!’ cried Lyte.

  They ran. Between the hot death and the cold one. Together, away from the cliffs, out toward the distant, beckoning ship.

  Never had they run this way in their lives. The sound of their feet running was a hard, insistent clatter over vast oblongs of rock, down into ravines, up the sides, and on again. They raked the air in and out of their lungs. Behind them the cliffs faded into things they could never turn back to now.

  They did not eat as they ran. They had eaten to the bursting point in the cave, to save time. Now it was only running, a lifting of legs, a balancing of bent elbows, a convulsion of muscles, a slaking in of air that had been fiery and was now cooling.

  ‘Are they watching us?’

  Lyte’s breathless voice snatched at his ears above the pound of his heart.

  Who? But he knew the answer. The cliff peoples, of course. How long had it been since a race like this one? A thousand days? Ten thousand? How long since someone had taken the chance and sprinted with an entire civilization’s eyes upon their backs, into gullies, across cooling plain. Were there lovers pausing in their laughter back there, gazing at the two tiny dots that were a man and woman running toward destiny? Were children eating of new fruits and stopping in their play to see the two people racing against time? Was Dienc still living, narrowing hairy eyebrows down over fading eyes, shouting them on in a feeble, rasping voice, shaking a twisted hand? Were there jeers? Were they being called fools, idiots? And in the midst of the name-calling, were people praying them on, hoping they would reach the ship?

  Sim took a quick glance at the sky, which was beginning to bruise with the coming night. Out of nowhere clouds materialized and a light shower trailed across a gully two hundred yards ahead of them. Lightning beat upon distant mountains and there was a strong scent of ozone on the disturbed air.

  ‘The halfway mark,’ panted Sim, and he saw Lyte’s face half turn, longingly looking back at the life she was leaving. ‘Now’s the time, if we want to turn back, we still have time. Another minute—’

  Thunder snarled in the mountains. An avalanche started out small and ended up huge and monstrous in a deep fissure. Light rain dotted Lyte’s smooth white skin. In a minute her hair was glistening and soggy with rain.

  ‘Too late, now,’ she shouted over the patting rhythm of her own naked feet. ‘We’ve got to go ahead!’

  And it was too late. Sim knew, judging the distances, that there was no turning back now.

  His leg began to pain him. He favored it, slowing. A wind came up swiftly. A cold wind that bit into the skin. But it came from the cliffs behind them, helped rather than hindered them. An omen? he wondered. No.

  For as the minutes went by it grew upon him how poorly he had estimated the distance. Their time was dwindling out, but they were still an impossible distance from the ship. He said nothing, but the impotent anger at the slow muscles in his legs welled up into bitterly hot tears in his eyes.

  He knew that Lyte was thinking the same as himself. But she flew along like a white bird, seeming hardly to touch ground. He heard her breath go out and in her throat, like a clean, sharp knife in its sheath.

  Half the sky was dark. The first stars were peering through lengths of black cloud. Lightning jiggled a path along a rim just ahead of them. A full thunderstorm of violent rain and exploding electricity fell upon them.

  They slipped and skidded on moss-smooth pebbles. Lyte fell, scrambled up again with a burning oath. Her body was scarred and dirty. The rain washed over her.

  The rain came down and cried on Sim. It filled his eyes and ran in rivers down his spine and he wanted to cry with it.

  Lyte fell and did not rise, sucking her breath, her breasts quivering.

  He picked her up and held her. ‘Run, Lyte, please, run!’

  ‘Leave me, Sim. Go ahead!’ The rain filled her mouth. There was water everywhere. ‘It’s no use. Go on without me.’

  He stood there, cold and powerless, his thoughts sagging, the flame of hope blinking out. All the world was blackness, cold falling sheaths of water, and despair.

  ‘We’ll walk, then,’ he said. ‘And keep walking, and resting.’

  They walked for fifty yards, easily, slowly, like children out for a stroll. The gully ahead of them filled with water that went sliding away with a swift wet sound, toward the horizon.

  Sim cried out. Tugging at Lyte he raced forward. ‘A new channel,’ he said, pointing. ‘Each day the rain cuts a new channel. Here, Lyte!’ He leaned over the floodwaters.

  He dived in, taking her with him.

  The flood swept them like bits of wood. They fought to stay upright, the water got into their mouths, their noses. The land swept by on both sides of them. Clutching Lyte’s fingers with insane strength, Sim felt himself hurled end over end, saw flicks of lightning on high, and a new fierce hope was born in him. They could no longer run—well, then they would let the water do the running for them.

  With a speed that dashed them against rocks, split open their shoulders, abraded their legs, the new, brief river carried them. ‘This way!’ Sim shouted over a
salvo of thunder and steered frantically toward the opposite side of the gully. The mountain where the ship lay was just ahead. They must not pass it by. They fought in the transporting liquid and were slammed against the far side. Sim leaped up, caught at an overhanging rock, locked Lyte in his legs, and drew himself hand over hand upward.

  As quickly as it had come, the storm was gone. The lightning faded. The rain ceased. The clouds melted and fell away over the sky. The wind whispered into silence.

  ‘The ship!’ Lyte lay upon the ground. ‘The ship, Sim. This is the mountain of the ship!’

  Now the cold came. The killing cold.

  They forced themselves drunkenly up the mountain. The cold slid along their limbs, got into their arteries like a chemical and slowed them.

  Ahead of them, with a fresh-washed sheen, lay the ship. It was a dream. Sim could not believe that they were actually so near it. Two hundred yards. One hundred and seventy yards.

  The ground became covered with ice. They slipped and fell again and again. Behind them the river was frozen into a blue-white snake of cold solidity. A few last drops of rain from somewhere came down as hard pellets.

  Sim fell against the bulk of the ship. He was actually touching it. Touching it! He heard Lyte whimpering in her constricted throat. This was the metal, the ship. How many others had touched it in the long days? He and Lyte had made it!

  Then, as cold as the air, his veins were chilled.

  Where was the entrance?

  You run, you swim, you almost drown, you curse, you sweat, you work, you reach a mountain, you go up it, you hammer on metal, you shout with relief, and then—you can’t find the entrance.

  He fought to control himself. Slowly, he told himself, but not too slowly, go around the ship. The metal slid under his searching hands, so cold that his hands, sweating, almost froze to it. Now, far around to the side. Lyte moved with him. The cold held them like a fist. It began to squeeze.

  The entrance.

  Metal. Cold, immutable metal. A thin line of opening at the sealing point. Throwing all caution aside, he beat at it. He felt his stomach seething with cold. His fingers were numb, his eyes were half frozen in their sockets. He began to beat and search and scream against the metal door. ‘Open up! Open up!’ He staggered. He had struck something…A click!
