IN THE BONE

 by

 Gordon R. Dickson

  

 Personally, his name was Harry Brennan.

 Officially, he was theJohn Paul Jones , which consisted of four billion dollars’ worth of irresistible equipment – the latest and best of human science – designed to spread its four thousand-odd components out through some fifteen cubic metres of space under ordinary conditions – designed also to stretch across light-years under extraordinary conditions (such as sending an emergency message-component home) or to clump into a single magnetic unit in order to shift through space and explore the galaxy. Both officially and personally – but most of all personally – he represents a case in point.

 The case is one having to do with the relative importance of the made thing and its maker.

 It was, as we know, the armoured horseman who dominated the early wars of the Middle Ages in Europe. But, knowing this, it is still wise to remember that it was not the iron shell that made the combination of man and metal terrible to the enemy – but rather the essentially naked man inside the shell. Later, French knights depending on their armour went down before the cloth-yard shafts of unarmoured footmen with bows, at Crécy and Poitiers.

 And what holds true for armour holds true for the latest developments of our science as well. It is not the spacecraft or the laser on which we will find ourselves depending when a time of ultimate decision comes, but the naked men within and behind these things. When that time comes, those who rank the made thing before its maker will die as the French knights died at Crécy and Poitiers. This is a law of nature as wide as the universe, which Harry Brennan, totally unsuspecting, was to discover once more for us, in his personal capacity.

 Personally, he was in his mid-twenties, unremarkable except for two years of special training with theJohn Paul Jones and his superb physical condition. He was five-eleven, a hundred and seventy-two pounds, with a round, cheerful face under his brown crew-cut hair. I was Public Relations Director of the Project that sent him out; and I was there with the rest to slap him on the back the day he left.

 “Don’t get lost, now,” said someone. Harry grinned.

 “The way you guys built this thing,” he answered, “if I got lost the galaxy would just have to shift itself around to get me back on plot.”

 There was an unconscious arrogance hidden in that answer, but no one marked it at the time. It was not the hour of suspicions.

 He climbed into the twelve-foot-tall control-suit that with his separate living tank were the main components of theJohn Paul Jones and took off. Up in orbit, he spent some thirty-two hours testing to make sure all the several thousand other component parts were responding properly. Then he left the solar system.

 He clumped together his components, made his first shift to orbit Procyon – and from there commenced his exploration of the stars. In the next nine weeks, he accumulated literally amazing amounts of new information about the nearby stars and their solar systems. And – this is an even better index of his success – located four new worlds on which men could step with never a spacesuit or even a water canteen to sustain them. Worlds so like Earth in gravity, atmosphere and even flora and fauna that they could be colonised tomorrow.

 Those were his first four worlds. On the fifth he encountered his fate – a fate for which he was unconsciously ripe.

 The fact was the medical men and psychologists had overlooked a factor – a factor having to do with the effect of Harry’s officialJohn Paul Jones self upon his entirely human personal self. And over nine weeks this effect had changed Harry without his ever having suspected it.

 You see, nothing seemed barred to him. He could cross light-years by touching a few buttons. He could send a sensing element into the core of the hottest star, into the most poisonous planetary atmospheres or crushing gravities, to look around as if he were down there in person. From orbit, he could crack open a mountain, burn off a forest or vaporise a section of icecap in search of information just by tapping the energy of a nearby sun. And so, subtly, the unconscious arrogance born during two years of training, that should have been noted in him at take-off from Earth, emerged and took him over – until he felt that there was nothing he could not do; that all things must give way to him; that he was, in effect, master of the universe.

 The day may come when a man like Harry Brennan may hold such a belief and be justified. But not yet. On the fifth Earthlike world he discovered – World 1242 in his records – Harry encountered the proof that his belief was unjustified.

 II

 The world was one which, from orbit, seemed to be the best of all the planets which he had discovered were suitable for human settlement; and he was about to go down to its surface personally in the control-suit, when his instruments picked out something already down there.

 It was a squat, metallic pyramid about the size of a four-plex apartment building; and it was radiating on a number of interesting frequencies. Around its base there was mechanical movement and an area of cleared ground. Further out, in the native forest, were treaded vehicles taking samples of the soil, rock and vegetation.

 Harry had been trained for all conceivable situations, including an encounter with other intelligent, space-going life. Automatically, he struck a specific button, and immediately a small torpedo-shape leaped away to shift through alternate space and back to Earth with the information so far obtained. And a pale, thin beam reached up and out from the pyramid below. Harry’s emergency messenger component ceased to exist.

 Shaken, but not yet really worried, Harry struck back instantly with all the power his official self could draw from the GO-type sun, nearby.

 The power was funnelled by some action below, directly into the pyramid itself; and it vanished there as indifferently as the single glance of a sunbeam upon a leaf.

 Harry’s mind woke suddenly to some understanding of what he had encountered. He reached for the controls to send theJohn Paul Jones shifting into the alternate universe and away.

 His hands never touched the controls. From the pyramid below, a blue lance of light reached up to paralyse him, select the control-suit from among the other components and send it tumbling to the planetary surface below like a swatted insect.

 But the suit had been designed to protect its occupant, whether he himself was operative or not. At fifteen hundred feet, the drag chute broke free, looking like a silver cloth candle-snuffer in the sunlight; and at five hundred feet the retro-rockets cut in. The suit tumbled to earth among some trees two kilometres from the pyramid, with Harry inside bruised, but released from his paralysis.

 From the pyramid, a jagged arm of something like white lightning lashed the ground as far as the suit, and the suit’s outer surface glowed cherry-red. Inside, the temperature suddenly shot up fifty degrees; instinctively Harry hit the panic button available to him inside the suit.

 The suit split down the centre like an overcooked frankfurter and spat Harry out; he rolled among the brush and fernlike ground cover, six or seven meters from the suit.

 From the distant pyramid, the lightning lashed the suit, breaking it up. The headpiece rolled drunkenly aside, turning the dark gape of its interior toward Harry like the hollow of an empty skull. In the dimness of that hollow Harry saw the twinkle of his control buttons.

 The lightning vanished. A yellow lightness filled the air about Harry and the dismembered suit. There was a strange quivering to the yellowness; and Harry half-smelled, half-tasted the sudden flatbite of ozone. In the headpiece a button clicked without being touched; and the suit speaker, still radio-connected with the recording tank in orbit, spoke aloud in Harry’s voice.

 “Orbit …” it said. “… into … going …”

 These were, in reverse order, the last three words Harry had recorded before sighting the pyramid. Now, swiftly gaining speed, the speaker began to recite backwards, word for word, everything Harry had said to it in nine weeks. Faster it went, and faster until it mounted to a chatter, a gabble, and finally a whine pushing against the upper limits of Harry’s auditory register.

 Suddenly, it stopped.

 The little clearing about Harry was full of silence. Only the odd and distant creaking of something that might have been a rubbing branch or an alien insect came to Harry’s ears. Then the speaker spoke once more.

 “Animal …” it said flatly in Harry’s calm, recorded voice and went on to pick further words from the recordings, “… beast. You … were an animal … wrapped in … made clothing. I have stripped you back to … animal again. Live, beast …”

 Then the yellowness went out of the air and the taste of ozone with it. The headpiece of the dismembered suit grinned, empty as old bones in the sunlight. Harry scrambled to his feet and ran wildly away through the trees and brush. He ran in panic and utter fear, his lungs gasping, his feet pounding the alien earth, until the earth, the trees, the sky itself swam about him from exhaustion; and he fell tumbling to earth and away into the dark haven of unconsciousness.

 When he woke, it was night, and he could not quite remember where he was or why. His thoughts seemed numb and unimportant. But he was cold, so he blundered about until he found the standing half-trunk of a lightning-blasted tree and crept into the burned hollow of its interior, raking frill-edged, alien leaves about him out of some half-forgotten instinct, until his own body-warmth in the leaves formed a cocoon of comfort about him; and he slept.

 From then on began a period in which nothing was very clear. It was as if his mind had huddled itself away somehow like a wounded animal and refused to think. There was no past or future, only the endless now. If now was warm, it had always been warm; if dark – it had always been dark. He learned to smell water from a distance and go to it when he was thirsty. He put small things in his mouth to taste them. If they tasted good he ate them. If he got sick afterwards, he did not eat them again.

 Gradually, blindly, the world about him began to take on a certain order. He came to know where there were plants with portions he could eat, where there were small creatures he could catch and pull apart and eat and where there was water.

 He did not know how lucky he was in the sheer chance of finding flora and fauna on an alien world that was edible – let alone nourishing. He did not realise that he had come down on a plateau in the tropical highlands, with little variation in day and night temperature and no large native predators which might have attacked him.

 None of this he knew. Now would it have made any difference to him if he had, for the intellectual centre of his brain had gone on vacation, so to speak, and refused to be called back. He was, in fact, a victim of severe psychological shock. The shock of someone who had come to feel himself absolute master of a universe and who then, in a few short seconds, had been cast down from that high estate by something or someone inconceivably greater, into the state of a beast of the field.

 But still, he could not be a true beast of the field, in spite of the fact that his intellectual processes had momentarily abdicated. His perceptive abilities still worked. His eyes could not help noting, even if incuriously, the progressive drying of the vegetation, the day-by-day shifting in the points of setting and rising of the sun. Slowly, instinctively, the eternal moment that held him stretched and lengthened until he began to perceive divisions within it – a difference betweennow andwas , betweennow andwill be .

  

 III

 The day came at last when he saw himself.

 A hundred times he had crouched by the water to drink and, lowering his lips to its surface, seen colour and shape rising to meet him. The hundredth and something time, he checked, a few inches above the liquid plane, staring at what he saw.

 For several long seconds it made no sense to him. Then, at first slowly, then with a rush like pain flooding back on someone rousing from the anaesthesia of unconsciousness, he recognised what he saw.

 Those were eyes at which he stared, sunken and dark-circled under a dirty tangle of hair. That was a nose jutting between gaunt and sunken cheeks above a mouth, and there was a chin naked only because once an ultrafine laser had burned out the thousand and one roots of the beard that grew on it. That was a man he saw –himself .

 He jerked back like someone who has come face-to-face with the devil. But he returned eventually, because he was thirsty, to drink and see himself again. And so, gradually, he got used to the sight of himself.

 So it was that memory started to return to him. But it did not come back quickly or all at once. It returned instead by jerks and sudden, partial revelations – until finally the whole memory of what had happened was back in his conscious mind again.

 But he was really not a man again.

 He was still essentially what the operator of the pyramid had broken him down into. He was still an animal. Only the memory and imaginings of a man had returned to live like a prisoner in a body that went on reacting and surviving in the bestial way it had come to regard as natural.

 But his animal peace was broken. For his imprisoned mind worked now. With the control-suit broken up – he had returned to the spot of its destruction many times, to gaze beastlike at the rusting parts – his mind knew he was a prisoner, alone on this alien world until he died. To know that was not so bad, but remembering this much meant remembering also the existence of the someone or something that had made him a prisoner here.

 The whoever it was who was in the pyramid.

 That the pyramid might have been an automated, mechanical device never entered his mind for a moment. There had been a personal, directed, living viciousness behind the announcement that had condemned him to live as a beast. No, in that blank-walled, metallic structure, whose treaded mechanical servants still prospected through the woods, there was something alive – something that could treat the awesome power of a solar tap as a human treated the attack of a mosquito – but somethingliving . Some being. Some Other, who lived in the pyramid, moving, breathing, eating and gloating – or worse yet, entirely forgetful of what he had done to Harry Brennan.

 And now that he knew that the Other was there, Harry began to dream of him nightly. At first, in his dreams, Harry whimpered with fear each time the dark shape he pursued seemed about to turn and show its face. But slowly, hatred came to grow inside and then outside his fear. Unbearable that Harry should never know the face of his destroyer. Lying curled in his nest of leaves under the moonless, star-brilliant sky, he snarled, thinking of his deprivation.

 Then hate came to strengthen him in the daylight also. From the beginning he had avoided the pyramid, as a wild coyote avoids the farmyard where he was once shot by the farmer. But now, day after day, Harry circled closer to the alien shape. From the beginning he had run and hidden from the treaded prospecting machines. But now, slowly, he grew bolder, standing close enough at last to touch them as they passed. And he found that they paid no attention to him. No attention at all.

 He came to ignore them in turn, and day by day he ventured closer to the pyramid. Until the morning came when he lay, silently snarling, behind a bush, looking out across the tread-trampled space that separated him from the nearest copper-coloured face of the pyramid.

 The space was roughly circular, thirty metres across, broken only by a small stream which had been diverted to loop inwards toward the pyramid before returning to its original channel. In the bight of the loop a machine like a stork straddled the artificial four-foot-wide channel, dipping a pair of long necks with tentacle-clustered heads into the water at intervals. Sometimes Harry could see nothing in the tentacles when they came up. Occasionally they carried some small water creature which they deposited in a tank.

 Making a perfect circle about the tramped area, so that the storklike machine was guarded within them, was an open fence of slender wands set upright in the earth, far enough apart for any of the machines that came and went to the forest to pass between any two of them. There seemed to be nothing connecting the wands, and nothing happened to the prospecting machines as they passed through – but the very purposelessness of the wands filled Harry with uneasiness.

 It was not until after several days of watching that he had a chance to see a small native animal, frightened by something in the woods behind it, attempt to bolt across a corner of the clearing.

 As it passed between two of the wands there was a waveriness in the air between them. The small animal leaped high, came down and lay still. It did not move after that, and later in the day, Harry saw the indifferent treads of one of the prospecting machines bury it in the trampled earth in passing.

 That evening, Harry brought several captive small animals bound with grass up to the wand line and thrust them through, one by one at different spots. All died.

 The next night he tried pushing a captive through a small trench scooped out so that the creature passed the killing line below ground level. But this one died also. For several days he was baffled. Then he tried running behind a slow-moving machine as it returned and tying a small animal to it with grass.

 For a moment as the front of the machine passed through, he thought the little animal would live. But then, as the back of the machine passed the line, it, too, died.

 Snarling, Harry paced around outside the circle in the brush until the sun set and stars filled the moonless sky.

 In the days that followed, he probed every gap in the wand-fence, but found no safe way through it. Finally, he came to concentrate on the two points at which the diverted stream entered and left the circle to flow beneath the storklike machine.

 He studied this without really knowing what he was seeking. He did not even put his studying into words. Vaguely, he knew that the water went in and the water came out again unchanged; and he also wished to enter and come out safely. Then, one day, studying the stream and the machine, he noticed that a small creature plucked from the water by the storklike neck’s mass of tentacles was still wriggling.

 That evening, at twilight, while there was still light to see, he waded up the two-foot depth of the stream to the point where the killing line cut across its water surface and pushed some more of his little animals toward the line underwater.

 Two of the three surfaced immediately, twitched and floated on limply, to be plucked from the water and cast aside on the ground by the storklike machine. But the third swam on several strokes before surfacing and came up living to scramble ashore, race for the forest and be killed by wands further around the circle.

 Harry investigated the channel below the killing line. There was water there up to his mid-thigh, plenty to cover him completely. He crouched down in the water and took a deep breath.

 Ducking below the surface, he pulled himself along with his fingertips, holding himself close to the bottom. He moved in as far as the tentacled ends. These grabbed at him, but could not reach far enough back to touch him. He saw that they came within a few inches of the gravel bottom.

 He began to need air. He backed carefully out and rose above the water, gasping. After a while his hard breathing stopped, and he sat staring at the water for a long while. When it was dark, he left.

 The next day he came and crept underwater to the grabbing area of the storklike machine again. He scooped out several handfuls of the gravel from under the place where the arms grabbed, before he felt a desperate need for air and had to withdraw. But that day began his labours.

  

 IV

 Four days later the bottom under the grasping tentacles was scooped out to an additional two feet of depth. And the fifth twilight after that, he pulled himself, dripping and triumphant, up out of the bend of the diverted stream inside the circle of the killing wands.

 He rested and then went to the pyramid, approaching it cautiously and sidelong like a suspicious animal. There was a door in the side he approached through which he had seen the prospecting machines trundle in and out. In the dimness he could not see it; and when he touched the metallic side of the structure, his fingers, grimed and toughened from scrabbling in the dirt, told him little. But his nose, beast-sensitive now, located and traced the outline of the almost invisible crack around the door panel by its reek of earth and lubricant.

 He settled down to wait. An hour later, one of the machines came back. He jumped up, ready to follow it in; but the door opened just before it and closed the minute it was inside – nor was there any room to squeeze in beside it. He hunkered down, disappointed, snarling a little to himself.

 He stayed until dawn and watched several more machines enter and leave. But there was no room to squeeze inside, even with the smallest of them.

 During the next week or so he watched the machines enter and leave nightly. He tied one of his small animals to an entering machine and saw it pass through the entrance alive and scamper out again with the next machine that left. And every night his rage increased. Then, wordlessly, one daytime after he had seen a machine deep in the woods lurch and tilt as its tread passed over a rock, inspiration took him.

 That night he carried through the water with him several cantaloupe-sized stones. When the first machine came back to the pyramid, in the moment in which the door opened before it, he pushed one of the rocks before the right-hand tread. The machine, unable to stop, mounted the rock with its right tread, tilted to the left and struck against that side of the entrance.

 It checked, backed off and put out an arm with the grasping end to remove the rock. Then it entered the opening. But Harry was already before it, having slipped through while the door was still up and the machine busy pulling the stone aside.

 He plunged into a corridor of darkness, full of clankings and smells. A little light from the opening behind him showed him a further, larger chamber where other machines stood parked. He ran toward them.

 Long before he reached them, the door closed behind him, and he was in pitch darkness. But the clanking of the incoming machine was close behind him, and the adrenalised memory of a wild beast did not fail him. He ran, hands outstretched, directly into the side of the parked machine at which he had aimed and clambered up on it. The machine entering behind him clanked harmlessly past him and stopped moving.

 He climbed cautiously down in the impenetrable darkness. He could see nothing; but the new, animal sensitivity of his nose offered a substitute for vision. He moved like a hunting dog around the chamber, sniffing and touching; and slowly a clear picture of it and its treaded occupants built up in his mind.

 He was still at this when suddenly a door he had not seen opened almost in his face. He had just time to leap backwards as a smaller machine with a boxlike body and a number of upward-thrusting arms entered, trundled to the machine that had just come back and began to relieve the prospecting machine of its sample box, replacing it with the one it carried itself.

 This much, in the dim light from the open door, Harry was able to see. But then, the smaller machine turned back toward the doorway; and Harry, waking to his opportunity, ducked through ahead of it.

 He found himself in a corridor dimly lit by a luminescent strip down the centre of its ceiling. The corridor was wide enough for the box-collecting machine to pass him; and, in fact, it rolled out around him as he shrank back against one metal wall. It went on down the corridor, and he followed it into a larger room with a number of machines, some mobile, some not, under a ceiling lit as the corridor had been with a crossing translucent strip.

 In this area all the machines avoided each other – and him. They were busy with each other and at other incomprehensible duties. Hunched and tense, hair erect on the back of his neck and nostrils spread wide, Harry moved through them to explore other rooms and corridors that opened off this one. It took him some little time; but he discovered that they were all on a level, and there was nothing but machines in any of them. He found two more doors with shallow steps leading up to them, but these would not open for him; and though he watched by one for some time, no machine went up the steps and through it.

 He began to be conscious of thirst and hunger. He made his way back to the door leading to the chamber where the prospecting machines were parked.  To his surprise, it opened as he approached it. He slipped through into darkness.

 Immediately, the door closed behind him; and sudden panic grabbed him, when he found he could not open it from this side. Then, self-possession returned to him.

 By touch, smell and memory, he made his way among the parked machines and down the corridor to the outside door. To his gratification, this also opened when he came close. He slipped through into cool, fresh outer air and a sky already greying with dawn. A few moments later, wet but free, he was back in the woods again.

 From then on, each night he returned. He found it was not necessary to do more than put any sizable object before a returning machine. It would stop to clear the path, and he could enter ahead of it. Then, shortly after he was inside, a box-collecting machine would open the inner door.

 Gradually, his fear of the machines faded. He came to hold them in a certain contempt. They always did the same thing in the same situation, and it was easy to trick or outmanoeuvre them.

 But the two inner doors of the machine area with the steps would not open to him; and he knew the upper parts of the pyramid were still unexplored by him. He sniffed at the cracks of these doors, and a scent came through – not of lubricating medium and metal alone, but of a different musky odour that raised the hairs on the back of his neck again. He snarled at the doors.

 He went back to exploring minutely the machine level. The sample boxes from the prospecting machines, he found, were put on conveyor-belt-like strips that floated up on thin air through openings in the ceiling – but the openings were too small for him to pass through. But he discovered something else. One day he came upon one of the machines taking a grille off the face of one of the immobile devices. It carried the grille away, and he explored the opening that had been revealed. It was the entrance to a tunnel or duct leading upward; and it was large enough to let him enter it. Air blew silently from it; and the air was heavy with the musky odour he had smelled around the doors that did not open.

 The duct tempted him, but fear held him back. The machine came back and replaced the grille; and he noticed that it fitted into place with a little pressure from the outside, top and bottom. After the machine had left he pressed, and the grille fell out into his hands.

 After a long wait, he ventured timorously into the tube – but a sudden sound like heavy breathing mixed with a wave of a strong, musky odour came at him. He backed out in panic, fled the pyramid and did not come back for two days.

 When he came back, the grille was again neatly in place. He removed it and sat a long time getting his courage up. Finally, he put the grille up high out of reach of the machine which had originally removed it and crawled into the duct.

 He crept up the tube at an angle into darkness. His eyes were useless, but the musky odour came strongly at him. Soon, he heard sounds.

 There was an occasional ticking, then a thumping or shuffling sound. Finally, after he had crawled a long way up through the tube, there was a sound like a heavy puffing or hoarse breathing. It was the sound that had accompanied the strengthening of the musky odour once before; and this time the scent came strong again.

 He lay, almost paralysed with terror in the tube, as the odour grew in his nostrils. He could not move until sound and scent had retreated. As soon as they had, he wormed his way backward down to the lower level and freedom, replaced the grille and fled for the outside air, once again.

 But once more, in time, he came back. Eventually returned to explore the whole network of tubes to which the one he had entered connected. Many of the branching tubes were too small for him to enter, and the biggest tube he could find led to another grille from which the musky-smelling air was blasted with force.

 Clearly it was the prime mover for the circulation of air through the exhaust half of the pyramid’s ventilating system. Harry did not reason it out to himself in those intellectual terms, but he grasped the concept wordlessly and went back to exploring those smaller tubes that he could crawl into.

 These, he found, terminated in grilles set in their floors through which he could look down and catch a glimpse of some chamber or other. What he saw was mainly incomprehensible. There were a number of corridors, a number of what could be rooms containing fixed or movable objects of various sizes and shapes. Some of them could be the equivalent of chairs or beds – but if so, they were scaled for a being plainly larger than himself. The lighting was invariably the low-key illumination he had encountered in the lower, machine level of the pyramid, supplied by the single translucent strip running across the ceiling.

 Occasionally, from one grille or another, he heard in the distance the heavy sound of breathing, among other sounds, and smelled more strongly the musky odour. But for more than a week of surreptitious visits to the pyramid, he watched through various grilles without seeing anything living.

  

 V

 However, a day finally came when he was crouched, staring down into a circular room containing what might be a bed shape, several chair shapes and a number of other fixed shapes with variously spaced and depthed indentations in their surfaces. In a far edge of the circular room was a narrow alcove, the walls of which were filled with ranked indentations, among which several lights of different colours winked and glowed.

 Suddenly, the dim illumination of the room began to brighten. The illumination increased rapidly, so that Harry cringed back from the grille, lifting a palm to protect his dimness-accustomed eyes. At the same moment, he heard approaching the sound of heavy breathing and sniffed a sudden increase in the musky odour.

 He froze. Motionless above the grille, he stopped even his breathing. He would have stopped his heart if he could, but it raced, shaking his whole body and sounding its rapid beat in his ears until he felt the noise of it must be booming through the pyramid like a drum. But there was no sign from below that this was so.

 Then, sliding into sight below him, came a massive figure on a small platform that seemed to drift without support into the room.

 The aperture of the grille was small. Harry’s viewpoint was cramped and limited, looking down directly from overhead. He found himself looking down onto thick, hairless, brown-skinned shoulders, a thick neck with the skin creased at the back and a forward-sloping, hairless brown head, egg-shaped in outline from above, with the point forward.

 Foreshortened below the head and shoulders was a bulging chinline with something like a tusk showing; it had a squat, heavy, hairless brown body and thick short forearms with stubby claws at the end of four-fingered hands. There was something walruslike about the tusks and the hunching – and the musky odour rose sickeningly into Harry’s human nostrils.

 The platform slid level with the alcove, which was too narrow for it to enter. Breathing hoarsely, the heavy figure on it heaved itself suddenly off the platform into the alcove, and the stubby hands moved over the pattern of indentations. Then, it turned and heaved itself out of the alcove, onto the flat, bed surface adjoining. Just as Harry’s gaze began to get a full-length picture of it, the illumination below went out.

 Harry was left, staring dazzled into darkness, while the heavy breathing and the sound of the figure readjusting itself on the bed surface came up to his ears. After a while, there was no noise but the breathing. But Harry did not dare move. For a long time he held his cramped posture, hardly breathing himself. Finally, cautiously, inch by inch, he retreated down the tube, which was too small to let him turn around. When he reached the larger tubes, he fled for the outside and the safety of the forest.

 The next day, he did not go near the pyramid. Or the next. Every time he thought of the heavy, brown figure entering the room below the grille, he became soaked with the clammy sweat of a deep, emotional terror. He could understand how the Other had not heard him or seen him up behind the grille. But he could not understand how the alien had notsmelledhim.

 Slowly, however, he came to accept the fact that the Other had not. Possibly the Other did not have a sense of smell. Possibly … there was no end to the possibilities. The fact was that the Other had not smelled Harry – or heard him – or seen him. Harry was like a rat in the walls – unknown because he was unsuspected.

 At the end of the week, Harry was once more prowling around back by the pyramid. He had not intended to come back, but his hatred drew him like the need of a drug addict for the drug of his addiction. He had to see the Other again, to feed his hate more surely. He had to look at the Other, while hating the alien, and feel the wild black current of his emotions running toward the brown and hairless shape. At night, buried in his nest of leaves, Harry tossed and snarled in his sleep, dreaming of the small stream backing up to flood the interior of the pyramid, and the Other drowning – of lightning striking the pyramid and fire racing through it – of the Other burning. His dreams became so full of rage and so terrible that he woke, twisting and with the few rags of clothing that still managed to cling unnoticed to him, soaked with sweat.

 In the end, he went back into the pyramid.

 Daily he went back. And gradually, it came to the point where he was no longer fearful of seeing the Other. Instead, he could barely endure the search and the waiting at the grilles until the Other came into sight. Meanwhile, outside the pyramid in the forest, the frill-edged leaves began to dry and wither and drop. The little stream sank in its bed – only a few inches, but enough so that Harry had to dig out the bottom of the streambed under the killing barrier in order to pass safely underwater into the pyramid area.

 One day he noticed that there were hardly any of the treaded machines out taking samples in the woods any more.

 He was on his way to the pyramid through the woods, when the realisation struck him. He stopped dead, freezing in midstride like a hunting dog. Immediately, there flooded into his mind the memory of how the parking chamber for the treaded machines, inside the base of the pyramid, had been full of unmoving vehicles during his last few visits.

 Immediately, also, he realised the significance of the drying leaves, the dropping of the water level of the stream. And something with the urgency of a great gong began to ring and ring inside him like the pealing of an alarm over a drowning city.

 Time had been when there had been no pyramid here. Time was now, with the year fading and the work of the collecting machines almost done. Time would be when the pyramid might leave.

 Taking with it the Other.

 He began to run, instinctively, toward the pyramid. But, when he came within sight of it, he stopped. For a moment he was torn with indecision, an emotional maelstrom of fear and hatred all whirling together.  Then, he went on.

 He emerged a moment later, dripping, a fist-sized rock in each hand, to stand before the closed door that gave the machines entrance to the pyramid. He stood staring at it, in broad daylight. He had never come here before in full daylight, but his head now was full of madness. Fury seethed in him, but there was no machine to open the door for him. It was then that the fury and madness in him might have driven him to pound wildly on the door with his stones or to wrench off one of the necks of the storklike machine at the stream and try to pry the door open. Any of these insane things he might have done and so have attracted discovery and the awesome power of the machinery and killing weapons at the command of the Other. Any such thing he might have done if he was simply a man out of his head with rage – but he was no longer a man.

 He was what the Other had made him, an animal, although with a man locked inside him. And like an animal, he did not rave or rant, any more than does the cat at the mousehole, or the wolf waiting for the shepherd to turn in for the night. Instead, without further question, the human beast that had been Harry Brennan – that still called himself Harry Brennan, in a little, locked-away, back corner of its mind – dropped on his haunches beside the door and hunkered there, panting lightly in the sunlight and waiting.

 Four hours later, as the sun was dropping close to the treetops, a single machine came trundling out of the woods. Harry tricked it with one of his stones and, still carrying the other, ran into the pyramid.

 He waited patiently for the small collecting machine to come and empty out the machine returned from outside, then dodged ahead of it, when it came, into the interior, lower level of the pyramid. He made his way calmly to the grille that gave him entrance to the ventilating system, took out the grille and entered the tube. Once in the system, he crawled through the maze of ductwork, until he came at last to the grille overlooking the room with the alcove and the rows of indentations on the alcove walls.

 When he looked down through the grille, it was completely dark below. He could hear the hoarse breathing and smell the musky odour of the Other, resting or perhaps asleep, on the bed surface. Harry lay there for a number of slow minutes, smelling and listening. Then he lifted the second rock and banged with it upon the grille.

 For a second there was nothing but the echoing clang of the beaten metal in the darkness. Then the room suddenly blazed with light, and Harry, blinking his blinded eyes against the glare, finally made out the figure of the Other rising upright upon the bed surface. Great, round yellow eyes in a puglike face with a thick upper lip wrinkled over two tusks stared up through the grille at Harry.

 The lip shifted, and a bubbling roar burst from the heavy fat-looking shape of the Other. He heaved his round body off the bed surface and rolled, waddling across the floor to just below the grille.

 Reaching up with one blunt-clawed hand, he touched the grille, and it fell to the floor at his feet. Left unguarded in the darkness of the ductwork, Harry shrank back. But the Other straightened up to his full near six and a half feet of height and reached up into the ductwork. His blunt clawed hand fastened on Harry and jerked. Off balance, Harry came tumbling to the floor of the chamber.

 A completely human man probably would have stiffened up and broken both arms, if not his neck, in such a fall. Harry, animal-like, attempted to cling to the shape of the Other as he fell, and so broke the impact of his landing. On the floor, he let go of the Other and huddled away from the heavy shape, whimpering.

 The Other looked down, and his round, yellow eyes focused on the stone Harry had clung to even through his fall. The Other reached down and grasped it, and Harry gave it up like a child releasing something he has been told many times not to handle. The Other made another, lower-toned, bubbling roar deep in his chest, examining the rock. Then he laid it carefully aside on a low table surface and turned back to stare down at Harry.

 Harry cringed away from the alien stare and huddled into himself, as the blunt fingers reached down to feel some of the rags of a shirt that still clung about his shoulders.

 The Other rumbled interrogatively at Harry. Harry hid his head. When he looked up again, the Other had moved over to a wall at the right of the alcove and was feeling about in some indentations there. He bubbled at the wall, and a second later Harry’s voice sounded eerily in the room.

 “… You are … the one I … made a beast …”

 Harry whimpered, hiding his head again.

 “You can’t …” said Harry’s voice, “… even speak now. Is … that so …?”

 Harry ventured to peek upward out of his folded arms, but ducked his head again at the sight of the cold, yellow eyes staring down at him.

 “… I thought … you would be … dead by now,” said the disembodied voice of Harry, hanging in the air of the chamber. “Amazing … survival completely without … equipment. Must keep you now …” The eyes, yellow as topaz, considered Harry, huddled abjectly on the floor, “… cage … collector’s item …”

 The alien revolved back to the indentations of the wall a little way from the alcove. The broad, fleshy back turned contemptuously on Harry, who stared up at it.

 The pitiful expression of fear on Harry’s face faded suddenly into a soundless snarl. Silently, he uncoiled, snatched up the rock the Other had so easily taken from him, and sprang with it onto the broad back.

 As he caught and clung there, one arm wrapped around a thick neck, the stone striking down on the hairless skull, his silent snarl burst out at last into the sound of a scream of triumph.

 The Other screamed too – a bubbling roar – as he clumsily turned, trying to reach around himself with his thick, short arms and pluck Harry loose. His claws raked Harry’s throat-encircling arm, and blood streamed from the arm; but it might have been so much stage makeup for the effect it had in loosening Harry’s hold. Screaming, Harry continued to pound crushingly on the Other’s skull. With a furious spasm, the alien tore Harry loose, and they both fell on the floor.

 The Other was first up; and for a second he loomed like a giant over Harry, as Harry was scrambling to his own feet and retrieving the fallen rock. But instead of attacking, the Other flung away, lunging for the alcove and the control indentations there.

 Harry reached the alcove entrance before him. The alien dodged away from the striking rock. Roaring and bubbling, he fled waddling from his human pursuer, trying to circle around the room and get back to the alcove. Half a head taller than Harry and twice Harry’s weight, he was refusing personal battle and putting all his efforts into reaching the alcove with its rows of indented controls. Twice Harry headed him off; and then by sheer mass and desperation, the Other turned and burst past into the alcove, thick hands outstretched and grasping at its walls. Harry leaped in pursuit, landing and clinging to the broad, fleshy back.

 The other stumbled under the added weight, and fell, face down. Triumphantly yelling, Harry rode the heavy body to the floor, striking at the hairless head … and striking … and striking …

  

 VI

 Sometime later, Harry came wearily to his senses and dropped a rock he no longer had the strength to lift. He blinked around himself like a man waking from a dream, becoming aware of a brilliantly lit room full of strange shapes – and of a small alcove, the walls of which were covered with rows of indentations, in which something large and dead lay with its head smashed into ruin. A deep, clawing thirst rose to take Harry by the throat, and he staggered to his feet.

 He looked longingly up at the dark opening of the ventilator over his head; but he was too exhausted to jump up, cling to its edge and pull himself back into the ductwork, from which he could return to the stream outside the pyramid and to the flowing water there. He turned and stumbled from the chamber into unfamiliar rooms and corridors.

 A brilliant light illuminated everything around him as he went. He sniffed and thought he scented, through the musky reek that filled the air about him, the clear odour of water. Gradually, the scent grew stronger and led him at last to a room where a bright stream leaped from a wall into a basin where it pooled brightly before draining away. He drank deeply and rested.

 Finally, satiated, he turned away from the basin and came face-to-face with a wall that was all reflecting surface; and he stopped dead, staring at himself, like Adam before the Fall.

 It was only then, with the upwelling of his returning humanness, that he realised his condition. And words spoken aloud for the first time in months broke harshly and rustily from his lips like the sounds of a machine unused for years.

 “My God!” he said, croakingly. “I’ve got no clothes left!”

 And he began to laugh. Cackling, cackling rasping more unnaturally even than his speech, his laughter lifted and echoed hideously through the silent, alien rooms. But it was laughter all the same – the one sound that distinguishes man from the animal.

 He was six months after that learning to be a complete human being again and finding out how to control the pyramid. If it had not been for the highly sophisticated safety devices built into the alien machine, he would never have lived to complete that bit of self-education.

 But finally he mastered the controls and got the pyramid into orbit, where he collected the rest of his official self and shifted back through the alternate universe to Earth.

 He messaged ahead before he landed; and everybody who could be there was on hand to meet him as he landed the pyramid. Some of the hands that had slapped his back on leaving were raised to slap him again when at last he stepped forth among them.

 But, not very surprisingly, when his gaunt figure in a spare coverall now too big for it, with shoulder-length hair and burning eyes, stepped into their midst, not one hand finished its gesture. No one in his right senses slaps an unchained wolf on the back; and no one, after one look, wished to risk slapping the man who seemed to have taken the place of Harry.

 Of course, he was still the same man they had sent out – ofcoursehe was. But at the same time he was also the man who had returned from a world numbered 1242 and from a duel to the death there with a representative of a race a hundred times more advanced than his own. And in the process he had been pared down to something very basic in his human blood and bone, something dating back to before the first crude wheel or chipped flint knife.

 And what was that? Go down into the valley of the shades and demand your answer of a dead alien with his head crushed in, who once treated the utmost powers of modern human science as a man treats the annoyance of a buzzing mosquito.

 Or, if that once-mighty traveller in space-going pyramids is disinclined to talk, turn and inquire of other ghosts you will find there – those of the aurochs, the great cave bear and the woolly mammoth.

 They, too, can testify to the effectiveness of naked men.
