Page 6 of Tunnel in the Sky


  Just now his business was to stay alive, for a period that he might as well figure as ten Earth days. He wiped Jimmy Throxton out of his mind, wiped out everything but the necessity of remaining unceasingly alert to all of his surroundings. He noted wind direction as shown by grass plumes and started crawling cautiously down wind.

  The decision to go down wind had been difficult. To go up wind had been his first thought, that being the natural direction for a stalk. But his sister’s advice had already paid off; he felt naked and helpless without a gun and it had reminded him that he was not the hunter. His scent would carry in any case; if he went down wind he stood a chance of seeing what might be stalking him, while his unguarded rear would be comparatively safe.

  Something ahead in the grass!

  He froze and watched. It had been the tiniest movement; he waited. There it was again, moving slowly from right to left across his front. It looked like a dark spike with a tuft of hair on the tip, a tail possibly, carried aloft.

  He never saw what manner of creature owned the tail, if it was a tail. It stopped suddenly at a point Rod judged to be directly down wind, then moved off rapidly and he lost Sight of it. He waited a few minutes, then resumed crawling.

  It was extremely hot work and sweat poured down him and soaked his overshirt and trousers. He began to want a drink very badly but reminded himself that five liters of water would not last long if he started drinking the first hour of the test. The sky was overcast with high cirrus haze, but the primary or “sun”—he decided to call it the Sun—seemed to burn through fiercely. It was low in the sky behind him; he wondered what it would be like overhead? Kill a man, maybe. Oh, well, it would be cooler in that forest ahead, or at least not be the same chance of sunstroke.

  There was lower ground ahead of him and hawklike birds were circling above the spot, round and round. He held still and watched. Brothers, he said softly, if you are behaving like vultures back home, there is something dead ahead of me and you are waiting to make sure it stays dead before you drop in for lunch. If so, I had better swing wide, for it is bound to attract other things…some of which I might not want to meet.

  He started easing to the right, quartering the light breeze. It took him onto higher ground and close to a rock outcropping. Rod decided to spy out what was in the lower place below, making use of cover to let him reach an overhanging rock.

  It looked mightily like a man on the ground and a child near him. Rod reached, fumbled in his vest pack, got out a tiny 8-power monocular, took a better look. The man was Johann Braun, the “child” was his boxer dog. There was no doubt but that they were dead, for Braun was lying like a tossed rag doll, with his head twisted around and one leg bent under. His throat and the side of his head were a dark red stain.

  While Rod watched, a doglike creature trotted out, sniffed at the boxer, and began tearing at it…then the first of the buzzard creatures landed to join the feast. Rod took the glass from his eye, feeling queasy. Old Yo had not lasted long—jumped by a “stobor” maybe—and his smart dog had not saved him. Too bad! But it did prove that there were carnivores around and it behooved him to be careful if he did not want to have jackals and vultures arguing over the leavings!

  He remembered something and put the glass back to his eye. Yo’s proud Thunderbolt gun was nowhere in sight and the corpse was not wearing the power pack that energized it. Rod gave a low whistle in his mind and thought. The only animal who would bother to steal a gun ran around on two legs. Rod reminded himself that a Thunderbolt could kill at almost any line-of-sight range—and now somebody had it who obviously took advantage of the absence of law and order in a survival test area.

  Well, the only thing to do was not to be in line of sight. He backed off the rock and slid into the bushes.

  The forest had appeared to be two kilometers away, or less, when he had started. He was close to it when he became uncomfortably aware that sunset was almost upon him. He became less cautious, more hurried, as he planned to spend the night in a tree. This called for light to climb by, since he relished a night on the ground inside the forest still less than he liked the idea of crouching helpless in the grass.

  It had not taken all day to crawl this far. Although it had been morning when he had left Templeton Gate the time of day there had nothing to do with the time of day here. He had been shoved through into late afternoon; it was dusk when he reached the tall trees.

  So dusky that he decided that he must accept a calculated risk for what he must do. He stopped at the edge of the forest, still in the high grass, and dug into his pack for his climbers. His sister had caused him to leave behind most of the gadgets, gimmicks, and special-purpose devices that he had considered bringing; she had not argued at these. They were climbing spikes of a style basically old, but refined, made small and light—the pair weighed less than a tenth of a kilogram—and made foldable and compact, from a titanium alloy, hard and strong.

  He unfolded them, snapped them under his arches and around his shins, and locked them in place. Then he eyed the tree he had picked, a tall giant deep enough in the mass to allow the possibility of crossing to another tree if the odds made a back-door departure safer and having a trunk which, in spite of its height, he felt sure he could get his arms around.

  Having picked his route, he straightened up and at a fast dogtrot headed for the nearest tree. He went past it, cut left for another tree, passed it and cut right toward the tree he wanted. He was about fifteen meters from it when something charged him.

  He closed the gap with instantaneous apportation which would have done credit to a Ramsbotham hyperfold. He reached the first branch, ten meters above ground, in what amounted to levitation. From there on he climbed more conventionally, digging the spurs into the tree’s smooth bark and setting his feet more comfortably on branches when they began to be close enough together to form a ladder.

  About twenty meters above ground he stopped and looked down. The branches interfered and it was darker under the trees than it had been out in the open; nevertheless he could see, prowling around the tree, the denizen that had favored him with attention.

  Rod tried to get a better view, but the light was failing rapidly. But it looked like…well, if he had not been certain that he was on some uncolonized planet ’way out behind and beyond, he would have said that it was a lion.

  Except that it looked eight times as big as any lion ought to look.

  He hoped that, whatever it was, it could not climb trees. Oh, quit fretting, Rod!—if it had been able to climb you would have been lunch meat five minutes ago. Get busy and rig a place to sleep before it gets pitch dark. He moved up the tree, keeping an eye out for the spot he needed.

  He found it presently, just as he was beginning to think that he would have to go farther down. He needed two stout branches far enough apart and near enough the same level to let him stretch a hammock. Having found such, he worked quickly to beat the failing light. From a pocket of his vest pack he took out his hammock, a web strong as spider silk and almost as thin and light. Using the line around his waist he stretched it, made sure his lashings would hold and then started to get into it.

  A double-jointed acrobat with prehensile toes might have found it easy; a slack-wire artist would simply have walked into it and sat down. But Rod found that he needed sky hooks. He almost fell out of the tree.

  The hammock was a practical piece of equipment and Rod had slept in it before. His sister had approved it, remarking that it was a better model than the field hammock they gave her girls. “Just don’t sit up in your sleep.”

  “I won’t,” Rod had assured her. “Anyway, I always fasten the chest belt.”

  But he had never slung it in this fashion. There was nothing to stand on under the hammock, no tree limb above it close enough to let him chin himself into it. After several awkward and breath-catching attempts he began to wonder whether he should perch like a bird the rest of the night, or drape himself in the notch of a limb. He did not consider sp
ending the night on the ground—not with that thing prowling around.

  There was another limb higher up almost directly over the hammock. Maybe if he tossed the end of his line over it and used it to steady himself…

  He tried it. But it was almost pitch dark now; the only reason he did not lose his line was that one end was bent to the hammock. At last he gave up and made one more attempt to crawl into the hammock by main force and extreme care. Bracing both hands wide on each side of the head rope he scooted his feet out slowly and cautiously. Presently he had his legs inside the hammock, then his buttocks. From there on it was a matter of keeping his center of gravity low and making no sudden moves while he insinuated his body farther down into the cocoon.

  At last he could feel himself fully and firmly supported. He took a deep breath, sighed, and let himself relax. It was the first time he had felt either safe or comfortable since passing through the gate.

  After a few minutes of delicious rest Rod located the nipple of his canteen and allowed himself two swallows of water, after which he prepared supper. This consisted in digging out a quarter-kilo brick of field ration, eleven hundred calories of yeast protein, fat, starch, and glucose, plus trace requirements. The label on it, invisible in the dark, certified that it was “tasty, tempting and pleasing in texture,” whereas chewing an old shoe would have attracted a gourmet quite as much.

  But real hunger gave Rod the best of sauces. He did not let any crumb escape and ended by licking the wrapper. He thought about opening another one, quelled the longing, allowed himself one more mouthful of water, then pulled the insect hood of the hammock down over his face and fastened it under the chest belt. He was immune to most insect-carried Terran diseases and was comfortably aware that humans were not subject to most Outlands diseases, but he did not want the night fliers to use his face as a drinking fountain, nor even as a parade ground.

  He was too hot even in his light clothing. He considered shucking down to his shorts; this planet, or this part of this planet, seemed quite tropical. But it was awkward; tonight he must stay as he was, even if it meant wasting a day’s ration of water in sweat. He wondered what planet this was, then tried to peer through the roof of the forest to see if he could recognize stars. But either the trees were impenetrable or the sky was overcast; he could see nothing. He attempted to draw everything out of his mind and sleep.

  Ten minutes later he was wider awake than ever. Busy with his hammock, busy with his dinner, he had not paid attention to distant sounds; now he became aware of all the voices of the night. Insects buzzed and sang and strummed, foliage rustled and whispered, something coughed below him. The cough was answered by insane laughter that ran raggedly up, then down, and died in asthmatic choking.

  Rod hoped that it was a bird.

  He found himself straining to hear every sound, near and far, holding his breath. He told himself angrily to stop it; he was safe from at least nine-tenths of potential enemies. Even a snake, if this place ran to such, would be unlikely to crawl out to the hammock, still less likely to attack—if he held still. Snakes, button-brained as they were, showed little interest in anything too big to swallow. The chances of anything big enough to hurt him—and interested in hurting him—being in this treetop were slim. So forget those funny noises, pal, and go to sleep. After all, they’re no more important than traffic noises in a city.

  He reminded himself of the Deacon’s lecture on alarm reaction, the thesis that most forms of death could be traced to the body’s coming too urgently to battle stations, remaining too long at full alert. Or, as his sister had put it, more people worry themselves to death than bleed to death. He set himself conscientiously to running through the mental routines intended to produce sleep.

  He almost made it. The sound that pulled him out of warm drowsiness came from far away; involuntarily he roused himself to hear it. It sounded almost human…no, it was human—the terrible sound of a grown man crying with heartbreak, the deep, retching, bass sobs that tear the chest.

  Rod wondered what he ought to do. It was none of his business and everyone there was on his own—but it went against the grain to hear such agony from a fellow human and ignore it. Should he climb down and feel his way through the dark to wherever the poor wretch was? Stumbling into tree roots, he reminded himself, and falling into holes and maybe walking straight into the jaws of something hungry and big.

  Well, should he? Did he have any right not to?

  It was solved for him by the sobs being answered by more sobs, this time closer and much louder. This new voice did not sound human, much as it was like the first, and it scared him almost out of his hammock. The chest strap saved him.

  The second voice was joined by a third, farther away. In a few moments the peace of the night had changed to sobbing, howling ululation of mass fear and agony and defeat unbearable. Rod knew now that this was nothing human, nor anything he had ever heard, or heard of, before. He suddenly had a deep conviction that these were the stobor he had been warned to avoid.

  But what were they? How was he to avoid them? The one closest seemed to be higher up than he was and no farther than the next tree…good grief, it might even be this tree!

  When you meet a stobor in the dark what do you do? Spit in its face? Or ask it to waltz?

  One thing was certain: anything that made that much noise in the jungle was not afraid of anything; therefore it behooved him to be afraid of it. But, there being nothing he could do, Rod lay quiet, his fear evidenced only by tense muscles, gooseflesh, and cold sweat. The hellish concert continued with the “stobor” closest to him sounding almost in his pocket. It seemed to have moved closer.

  With just a bit more prodding Rod would have been ready to sprout wings and fly. Only at home on the North American continent of Terra had he ever spent a night alone in the wilderness. There the hazards were known and minor…a few predictable bears, an occasional lazy rattlesnake, dangers easily avoided.

  But how could he guard against the utterly unknown? That stobor—he decided that he might as well call it that—that stobor might be moving toward him now, sizing him up with night eyes, deciding whether to drag him home, or eat him where it killed him.

  Should he move? And maybe move right into the fangs of the stobor? Or should he wait, helpless, for the stobor to pounce? It was possible that the stobor could not attack him in the tree. But it was equally possible that stobor were completely arboreal and his one chance lay in climbing down quickly and spending the night on the ground.

  What was a stobor? How did it fight? Where and when was it dangerous? The Deacon evidently expected the class to know what to do about them. Maybe they had studied the stobor those days he was out of school right after New Year’s? Or maybe he had just plain forgotten…and would pay for it with his skin. Rod was good at Outlands zoology—but there was just too much to learn it all. Why, the zoology of Terra alone used to give oldstyle zoologists more than they could handle; how could they expect him to soak up all there was to learn about dozens of planets?

  It wasn’t fair!

  When Rod heard himself think that ancient and useless protest he had a sudden vision of the Deacon’s kindly, cynical smile. He heard his dry drawl: Fair? You expected this to be fair, son? This is not a game. I tried to tell you that you were a city boy, too soft and stupid for this. You would not listen.

  He felt a gust of anger at his instructor; it drove fear out of his mind. Jimmy was right; the Deacon would eat his own grandmother! A cold, heartless fish!

  All right, what would the Deacon do?

  Again he heard his teacher’s voice inside his head, an answer Matson had once given to a question put by another classmate: “There wasn’t anything I could do, so I took a nap.”

  Rod squirmed around, rested his hand on “Colonel Bowie” and tried to take a nap. The unholy chorus made it almost impossible, but he did decide that the stobor in his tree—or was it the next tree?—did not seem to be coming closer. Not that it could come much close
r without breathing on his neck, but at least it did not seem disposed to attack.

  After a long time he fell into restless sleep, sleep that was no improvement, for he dreamed that he had a ring of sobbing, ululating stobor around him, staring at him, waiting for him to move. But he was trussed up tight and could not move.

  The worst of it was that every time he turned his head to see what a stobor looked like it would fade back into the dark, giving him just a hint of red eyes, long teeth.

  He woke with an icy shock, tried to sit up, found himself restrained by his chest strap, forced himself to lie back. What was it? What had happened?

  In his suddenly-awakened state it took time to realize what had happened: the noise had stopped. He could not hear the cry of a single stobor, near or far. Rod found it more disturbing than their clamor, since a noisy stobor advertised its location whereas a silent one could be anywhere—why, the nearest one could now be sitting on the branch behind his head. He twisted his head around, pulled the insect netting off his face to see better. But it was too dark; stobor might be queued up three abreast for all he could tell.

  Nevertheless the silence was a great relief. Rod felt himself relax as he listened to the other night sounds, noises that seemed almost friendly after that devils’ choir. He decided that it must be almost morning and that he would do well to stay awake.

  Presently he was asleep.

  He awoke with the certainty that someone was looking at him. When he realized where he was and that it was still dark, he decided that it was a dream. He stirred, looked around, and tried to go back to sleep.

  Something was looking at him!

  His eyes, made sensitive by darkness, saw the thing as a vague shape on the branch at his foot. Black on black, he could not make out its outline—but two faintly luminous eyes stared unwinkingly back into his.
