Tunnel in the Sky

  “—nothing I could do, so I took a nap.” Rod did not take a nap. For a time measured in eons he and the thing in the tree locked eyes. Rod tightened his grip on his knife and held still, tried to quell the noise of his pounding heart, tried to figure out how he could fight back from a hammock. The beast did not move, made no sound; it simply stared and seemed prepared to do it all night.

  When the ordeal had gone on so long that Rod felt a mounting impulse to shout and get it over, the creature moved with light scratching sounds toward the trunk and was gone. Rod could feel the branch shift; he judged that the beast must weigh as much as he did.

  Again he resolved to stay awake. Wasn’t it getting less dark? He tried to tell himself so, but he still could not see his own fingers. He decided to count to ten thousand and bring on the dawn.

  Something large went down the tree very fast, followed at once by another, and still a third. They did not stop at Rod’s bedroom but went straight down the trunk. Rod put his knife back and muttered, “Noisy neighbors! You’d think this was Emigrants’ Gap.” He waited but the frantic procession never came back.

  He was awakened by sunlight in his face. It made him sneeze; he tried to sit up, was caught by his safety belt, became wide awake and regretted it. His nose was stopped up, his eyes burned, his mouth tasted like a ditch, his teeth were slimy, and his back ached. When he moved to ease it he found that his legs ached, too—and his arms—and his head. His neck refused to turn to the right.

  Nevertheless he felt happy that the long night was gone. His surroundings were no longer terrifying, but almost idyllic. So high up that he could not see the ground he was still well below the roof of the jungle and could not see sky; he floated in a leafy cloud. The morning ray that brushed his face was alone, so thoroughly did trees shut out the sky.

  This reminded him that he had to mark the direction of sunrise. Hmm…not too simple. Would he be able to see the sun from the floor of the jungle? Maybe he should climb down quickly, get out in the open, and mark the direction while the sun was still low. But he noticed that the shaft which had wakened him was framed by a limb notch of another forest giant about fifteen meters away. Very well, that tree was “east” of his tree; he could line them up again when he reached the ground.

  Getting out of his hammock was almost as hard as getting in; sore muscles resented the effort. At last he was balanced precariously on one limb. He crawled to the trunk, pulled himself painfully erect and, steadied by the trunk, took half-hearted setting-up exercises to work the knots out. Everything loosened up but his neck, which still had a crick like a toothache.

  He ate and drank sitting on the limb with his back to the trunk. He kept no special lookout, rationalizing that night feeders would be bedded down and day feeders would hardly be prowling the tree tops—not big ones, anyway; they would be on the ground, stalking herbivores. The truth was that his green hide-away looked too peaceful to be dangerous.

  He continued to sit after he finished eating, considered drinking more of his precious water, even considered crawling back into his hammock. Despite the longest night he had ever had he was bone tired and the day was already hot and sleepy and humid; why not stretch out? His only purpose was to survive; how better than by sleeping and thereby saving food and water?

  He might have done so had he known what time it was. His watch told him that it was five minutes before twelve, but he could not make up his mind whether that was noon on Sunday or midnight coming into Monday. He was sure that this planet spun much more slowly than did Mother Earth; the night before had been at least as long as a full Earth day.

  Therefore the test had been going on at least twenty six hours and possibly thirty-eight—and recall could be any time after forty-eight hours. Why, it might be today, before sunset, and here he was in fine shape, still alive, still with food and water he could trust.

  He felt good about it. What did a stobor have that a man did not have more of and better? Aside from a loud voice, he added.

  But the exit gate might be as much as twenty kilometers “east” of where he had come in; therefore it behooved him to reach quickly a point ten kilometers east of where he had come in; he would lay money that that would land him within a kilometer or two of the exit. Move along, hole up, and wait—why, he might sleep at home tonight, after a hot bath!

  He started unlashing his hammock while reminding himself that he must keep track of hours between sunrise and sunset today in order to estimate the length of the local day. Then he thought no more about it as he had trouble folding the hammock. It had to be packed carefully to fit into a pocket of his vest pack. The filmy stuff should have been spread on a table, but where he was the largest, flattest area was the palm of his hand.

  But he got it done, lumpy but packed, and started down. He paused on the lowest branch, looked around. The oversized and hungry thing that had chased him up the tree did not seem to be around, but the undergrowth was too dense for him to be sure. He made a note that he must, all day long and every day, keep a climbable tree in mind not too far away; a few seconds woolgathering might use up his luck.

  Okay, now for orientation—Let’s see, there was the tree he had used to mark “east.” Or was it? Could it be that one over there? He realized that he did not know and swore at himself for not checking it by compass. The truth was that he had forgotten that he was carrying a compass. He got it out now, but it told him nothing, since east by compass bore no necessary relation to direction of sunrise on this planet. The rays of the primary did not penetrate where he was; the forest was bathed by a dim religious light unmarked by shadows.

  Well, the clearing could not be far away. He would just have to check. He descended by climbing spurs, dropped to spongy ground, and headed the way it should be. He counted his paces while keeping an eye peeled for hostiles.

  One hundred paces later he turned back, retracing his own spoor. He found “his” tree; this time he examined it. There was where he had come down; he could see his prints. Which side had he gone up? There should be spur marks.

  He found them…and was amazed at his own feat; they started high as his head. “I must have hit that trunk like a cat!” But it showed the direction from which he had come; five minutes later he was at the edge of the open country he had crossed the day before.

  The sun made shadows here, which straightened him out and he checked by compass. By luck, east was “east” and he need only follow his compass. It took him back into the forest.

  He traveled standing up. The belly sneak which he had used the day before was not needed here; he depended on moving noiselessly, using cover, and keeping an eye out behind as well as in front. He zigzagged in order to stay close to trees neither too big nor too small but corrected his course frequently by compass.

  One part of his mind counted paces. At fifteen hundred broken-country steps to a kilometer Rod figured that fifteen thousand should bring him to his best-guess location for the exit gate, where he planned to set up housekeeping until recall.

  But, even with part of his mind counting paces and watching a compass and a much larger part watching for carnivores, snakes, and other hazards, Rod still could enjoy the day and place. He was over his jitters of the night before, feeling good and rather cocky. Even though he tried to be fully alert, the place did not feel dangerous now—stobor or no stobor.

  It was, he decided, jungle of semi-rainforest type, not dense enough to require chopping one’s way. It was interlaced with game paths but he avoided these on the assumption that carnivores might lie waiting for lunch to come down the path—Rod had no wish to volunteer.

  The place seemed thick with game, mostly of antelope type in many sizes and shapes. They were hard to spot; they faded into the bush with natural camouflage, but the glimpses he got convinced him that they were plentiful. He avoided them as he was not hunting and was aware that even a vegetarian could be dangerous with hooves and horns in self or herd defense.

  The world above was inhabited, too, w
ith birds and climbers. He spotted families of what looked like monkeys and speculated that this world would probably have developed its own race of humanoids. He wondered again what planet it was? Terrestrial to several decimal places it certainly seemed to be—except for the inconveniently long day—and probably one just opened, or it would be swarming with colonists. It would be a premium planet certainly; that clearing he had come through yesterday would make good farm land once it was burned off. Maybe he would come back some day and help clean out the stobor.

  In the meantime he watched where he put his hands and feet, never walked under a low branch without checking it, and tried to make his eyes and ears as efficient as a rabbit’s. He understood now what his sister had meant about how being unarmed makes a person careful, and realized also how little chance he would have to use a gun if he let himself be surprised.

  It was this hyperacuteness that made him decide that he was being stalked.

  At first it was just uneasiness, then it became a conviction. Several times he waited by a tree, stood frozen and listened; twice he did a sneak through bushes and doubled back on his tracks. But whatever it was seemed as good as he was at silent movement and taking cover and (he had to admit) a notch better.

  He thought about taking to the trees and outwaiting it. But his wish to reach his objective outweighed his caution; he convinced himself that he would be safer if he pushed on. He continued to pay special attention to his rear, but after a while he decided that he was no longer being followed.

  When he had covered, by his estimate, four kilometers, he began to smell water. He came to a ravine which sliced across his route. Game tracks led him to think it might lead down to a watering place, just the sort of danger area he wished to avoid, so Rod crossed quickly and went down the shoulder of the ravine instead. It led to a bank overlooking water; he could hear the stream before he reached it.

  He took to the bushes and moved on his belly to a point where he could peer out from cover. He was about ten meters higher than the water. The ground dropped off on his right as well as in front; there the ravine joined the stream and an eddy pool formed the watering place he had expected. No animals were in sight but there was plenty of sign; a mud flat was chewed with hoof marks.

  But he had no intention of drinking where it was easy; would be too easy to die there. What troubled him was that he must cross the stream to reach the probable recall area. It was a small river or wide brook, not too wide to swim, probably not too deep to wade if he picked his spot. But he would not do either one unless forced—and not then without testing the water by chucking a lure into it…a freshly killed animal. The streams near his home were safe, but a tropical stream must be assumed to have local versions of alligator, piranha, or even worse.

  The stream was too wide to cross through the tree tops. He lay still and considered the problem, then decided that he would work his way upstream and hope that it would narrow, or split into two smaller streams which he could tackle one at a time.

  It was the last thing he thought about for some time.

  When Rod regained consciousness it was quickly; a jackal-like creature was sniffing at him. Rod lashed out with one hand and reached for his knife with the other. The dog brute backed away, snarling, then disappeared in the leaves.

  His knife was gone! The realization brought him groggily alert; he sat up. It made his head swim and hurt. He felt it and his fingers came away bloody. Further gingerly investigation showed a big and very tender swelling on the back of his skull, hair matted with blood, and failed to tell him whether or not his skull was fractured. He gave no thanks that he had been left alive; he was sure that the blow had been intended to kill.

  But not only his knife was gone. He was naked, save for his shorts. Gone were his precious water, his vest pack with rations and a dozen other invaluable articles—his antibiotics, his salt, his compass, his climbers, his matches, his hammock…everything.

  His first feeling of sick dismay was replaced by anger. Losing food and gear was no more than to be expected, since he had been such a fool as to forget his rear while he looked at the stream—but taking the watch his father had given him, that was stealing; he would make somebody pay for that!

  His anger made him feel better. It was not until then that he noticed that the bandage on his left shin was undisturbed.

  He felt it. Sure enough! Whoever it was who had hijacked him had not considered a bandage worth stealing; Rod unwrapped it and cradled Lady Macbeth in his hand.

  Somebody was going to be sorry.

  Savage

  ROD WALKER WAS CROUCHING ON A TREE LIMB. He had not moved for two hours, he might not move for as long a time. In a clearing near him a small herd of yearling bachelor buck were cropping grass; if one came close enough Rod intended to dine on buck. He was very hungry.

  He was thirsty, too, not having drunk that day. Besides that, he was slightly feverish. Three long, imperfectly healed scratches on his left arm accounted for the fever, but Rod paid fever and scratches no attention—he was alive; he planned to stay alive.

  A buck moved closer to him; Rod became quiveringly alert. But the little buck tossed his head, looked at the branch, and moved away. He did not appear to see Rod; perhaps his mother had taught him to be careful of overhanging branches—or perhaps a hundred thousand generations of harsh survival had printed it in his genes.

  Rod swore under his breath and lay still. One of them was bound to make a mistake eventually; then he would eat. It had been days since he had thought about anything but food…food and how to keep his skin intact, how to drink without laying himself open to ambush, how to sleep without waking up in a fellow-denizen’s belly.

  The healing wounds on his arm marked how expensive his tuition had been. He had let himself get too far from a tree once too often, had not even had time to draw his knife. Instead he had made an impossible leap and had chinned himself with the wounded arm. The thing that had clawed him he believed to be the same sort as the creature that had treed him the day of his arrival; furthermore he believed it to be a lion. He had a theory about that, but had not yet been able to act on it.

  He was gaunt almost to emaciation and had lost track of time. He realized that the time limit of the survival test had probably—almost certainly—passed, but he did not know how long he had lain in the crotch of a tree, waiting for his arm to heal, nor exactly how long it had been since he had come down, forced by thirst and hunger. He supposed that the recall signal had probably been given during one of his unconscious periods, but he did not worry nor even think about it. He was no longer interested in survival tests; he was interested in survival.

  Despite his weakened condition his chances were better now than when he had arrived. He was becoming sophisticated, no longer afraid of things he had been afraid of, most acutely wary of others which had seemed harmless. The creatures with the ungodly voices which he had dubbed “stobor” no longer fretted him; he had seen one, had disturbed it by accident in daylight and it had given voice. It was not as big as his hand, and reminded him of a horned lizard except that it had the habits of a tree toad. Its one talent was its voice; it could blow up a bladder at its neck to three times its own size, then give out with that amazing, frightening sob.

  But that was all it could do.

  Rod had guessed that it was a love call, then had filed the matter. He still called them “stobor.”

  He had learned about a forest vine much like a morning glory, but its leaves carried a sting worse than that of a nettle, toxic and producing numbness. Another vine had large grape-like fruits, deliciously tempting and pleasant to the palate; Rod had learned the hard way that they were a powerful purgative.

  He knew, from his own narrow brushes and from kills left half-eaten on the ground, that there were carnivores around even though he had never had a good look at one. So far as he knew there were no carnivorous tree-climbers large enough to tackle a man, but he could not be certain; he slept with one
eye open.

  The behavior of this herd caused him to suspect that there must be carnivores that hunted as he was now hunting, even though he had had the good fortune not to tangle with one. The little buck had wandered all over the clearing, passed close by lesser trees, yet no one of them had grazed under the tree Rod was in.

  Steady, boy…here comes one. Rod felt the grip of “Lady Macbeth,” got ready to drop onto the graceful little creature as it passed under. But five meters away it hesitated, seemed to realize that it was straying from its mates, and started to turn.

  Rod let fly.

  He could hear the meaty tunk! as blade bit into muscle; he could see the hilt firm against the shoulder of the buck. He dropped to the ground, hit running and moved in to finish the kill.

  The buck whipped its head up, turned and fled. Rod dived, did not touch it. When he rolled to his feet the clearing was empty. His mind was filled with bitter thoughts; he had promised himself never to throw his knife when there was any possibility of not being able to recover it, but he did not let regrets slow him; he got to work on the tracking problem.

  Rod had been taught the first law of hunting sportsmanship, that a wounded animal must always be tracked down and finished, not left to suffer and die slowly. But there was no trace of “sportsmanship” in his present conduct; he undertook to track the buck because he intended to eat it, and—much more urgently—because he had to recover that knife in order to stay alive.

  The buck had not bled at once and its tracks were mixed up with hundreds of other tracks. Rod returned three times to the clearing and started over before he picked up the first blood spoor. After that it was easier but he was far behind now and the stampeded buck moved much faster than he could track. His quarry stayed with the herd until it stopped in a new pasture a half kilometer away. Rod stopped still in cover and looked them over. His quarry did not seem to be among them.
