The Man-Kzin Wars 01

by Larry Niven

  The sunblaze fooled him, dying slowly while it was still halfway to his horizon. He punched the time into his wristcomp, and realized that the builders of this zoo might be limited in the degree to which they could surrogate a planetary surface, when other vast circular cages were adjacent to this one. It was too much to ask that any zoo cage be, for its specimens, the best of all possible worlds.

  Locklear slept badly, but he slept. During the times when he lay awake, he felt the silence like a hermetic seal around him, broken only by the rasp and slither of distant tree fronds in vagrant breezes. Kzin-normal microorganisms, the navigator had said; maybe, but Locklear had seen no sign of animal life. Almost, he would have preferred stealthy footfalls or screams of nocturnal prowlers.

  The next morning he noted on his wristcomp when the ersatz kzinti sun began to blaze-not on the horizon, but seeming to kindle when halfway to its zenith-rigged a better sling for his right arm, then sat scratching in the dirt for a time. The night had lasted thirteen hours and forty-eight minutes. If succeeding nights were longer, he was in for a tooth-chattering winter. But first: FIND THAT DAMNED TRANSMITTER.

  Because it was small enough to fit in a pocket. And then, A then, he would not be held like a lap-dog on a leash. He pounded some kzin meat to soften it and took his first sightings while swilling from a water bull).

  The extension of that measured line, this time in the opposite direction, went more quickly except when he had to clamber on rocky inclines or cut one of those pulpy trees down to keep his sightings near perfect. He had no spirit level, but estimated the inclines as well as he could, as he had done before, and used the wristcomp's trigonometric functions to adjust the numbers he took from his surveying thread. That damned kzin engineer was the kind who would be half-running to do his master's bidding, and an eight-cubed of his paces might be anywhere from six hundred meters to a kilometer. Or the hidden transmitter might be almost underfoot at the cache; but no more than a klick at most. Locklear was pondering that when the zzrou zapped him again.

  He stiffened, yelped, and whirled back several paces, then advanced very slowly until he felt its first half-hearted bite, and moved back, punching in the datum, working backward using the same system to make doubly sure of his numbers. At the cache, he found his two new numbers varied by five meters and split the difference. His southwest limit had been 437 meters away, his northeast limit 529; which meant the total length of that line was 966 meters. It probably wasn't the full diameter of his circle, but those points lay on its circumference. He halved the number: 483. That number, minus the 437, was 46 meters. He measured off forty-six meters toward the northeast and piled pulpy branches in a pyramid higher than his head. This point, by God, was one point on the full diameter of that circle perpendicular to his first line! Next he had to survey a line at a right angle to the line he'd already surveyed, a line passing through that pyramid of branches.

  It took him all morning and then some, lengthening his thread to be more certain of that crucial right-angle before he set off into the jungle, and he measured almost seven hundred meters before that bloody damned zzrou bit him again, this time not so painfully because by that time he was moving very slowly. He returned to the pyramid of branches and struck off in the opposite direction, just to be sure of the numbers he scratched in the dirt using the wristcomp. He was filled with joy when the zzrou faithfully poisoned him a bit over 300 meters away, within ten meters of his expectation.

  Those first three limit points had been enough to rough out the circle; the fourth was confirmation. Locklear knew that he had passed the transmitter on that long northwest leg; calculated quickly, because he knew the exact length of that diameter, that it was a bit over two hundred meters from his pyramid; and measured off the distance after lunch.

  “I just like that fur-licking bastard," he said, looking around him at the tangle of orange, green, and yellow jungle growth. “Probably shit on it before he buried it. “

  Locklear spent a fruitless hour clearing punky shrubs and man-high ferns from the soft turf before he saw it, and of course it was not where he had been looking at all. “It" was not a telltale mound of dirt, nor a kzin footprint. It was a group of three globes of milky sap, no larger than water droplets, just about knee-high on the biggest palm in the clearing. And just about the right pattern for a kzin's toe-claws.

  He moved around the trunk, as thick as his body, staring up the tree, now picking out other sets of milky puncture marks spaced up the trunk. More kzin clawmarks. Softly, feeling the gooseflesh move down his arms, he called, “Ollee-ollee-all's-in-free” , just for the hell of it. And then he cut the damned tree down, carefully, letting the breeze do part of the work so that the tree sagged, buckled, and came down at a leisurely pace.

  The transmitter, which looked rather like a wristcomp without a bracelet, lay in a hole scooped out by Yellowbelly's claws in the tender young top of the tree. It was sticky with sap, and Locklear hoped it had stung the kzin as it was stinging his own fingers. He wiped it off with vine leaves, rinsed it with dribbles of water from severed vines, wiped it off again, and then returned to his food cache.

  “Yep, the shoulder hurts, and the damned gravity doesn't help but," he said, and yelled it at the sky, now I'm loose, you rat-tailed sons of bitches!"

  He spent another night at the first cache, now with little concern about things that went bump in the ersatz night. The sunblaze dimmed thirteen hours and forty-eight minutes after it began, and Locklear guessed that the days and nights of this synthetic arena never changed. “It'd be tough to develop a cosmology here," he said aloud, shivering because his right shoulder simply would not let him generate a fire by friction. “Maybe that was deliberate." If he wanted to study the behavior of intelligent species without risking their learning too much, and had not the faintest kind of ethics about it, Locklear decided he might imagine just such a vast enclosure for the kzinti. Only they were already a spacefaring race, and so was humankind, and he could have sworn the adjacent area on this impossible zoo planet was a ringer for one of the wild areas back on Earth. He cudgeled his memory until he recalled the lozenge shape of that lake seen from orbit, and the earthlike area.

  “Right-about-there," he said, nodding to the southwest, across the lake. “If I don't starve first.”

  He knew that any kzinti searching for him could simply home in on the transmitter. Or maybe not so simply, if the signal was blocked by stone or dirt. A cave with a kink in it could complicate their search nicely. He could test the idea-at the risk of absorbing one zap too many from that infuriating zzrou clinging to his back.

  “Well, second things second , he said. He'd at tended to the first things first. He slept poorly again, but the collarbone seemed to be mending. Locklear admitted an instant's panic the next morning (he had counted down to the moment when the ersatz sun began to shine, missing it by a few seconds) as he moved beyond his old limit toward the lake. But the zzrou might have been a hockey puck for its inertness. The lake had small regular wavelets easy enough to generate if you have a timer on your gravity polarizer, he mused to the builders-and a narrow beach that alternated between sand and pebbles. No prints of any kind, not even birds or mollusks. If this huge arena did not have extremes of weather, a single footprint on that sand might last a geologic era.

  The food cache was within a stone's throw of the kzin landing, good enough reason to find a better place. Locklear found one, where a stream trickled to the lake (pumps, or rainfall? Time enough to find out), after cutting its passage down through basalt that was half-hidden by foliage. Locklear found a hollow beneath a low waterfall and, in three trips, portaged all his meager stores to that hideyhole with its stone shelf. The water tasted good, and again he tested the trickle from slashed vines because he did not intend to stay tied to that lakeside forever.

  The channel cut through basalt by water told him that the stream had once been a torrent and might be again. The channel also hinted that the stream had been cutting its patie
nt way for tens of centuries, perhaps far longer. “Zoo has been here a long time," he said, startled at the tinny echo behind the murmur of water, realizing that he had begun to think of this planet as “Zoo." It might be untenanted, like that sad remnant of a capitalist's dream that still drew tourists to San Simeon on the coast of Earth's California. Cages for exotic fauna, but the animals long since gone. Or never introduced? One more puzzle to be shelved until more pieces could be studied.

  During his fourth day on Zoo, Locklear realized that the water was almost certainly safe, and that he must begin testing the tubers, spiny nuts, and poisonous-looking fruit that he had been eyeing with mistrust. Might as well test the stuff while circumnavigating the lake, he decided, vowing to try one new plant a day. Nothing had nibbled at anything beyond mosslike growths on some soft-surfaced fruit. He guessed that the growths meant that the fruit was over-ripe, and judged ripeness that way. He did not need much time deciding about plants that stank horribly, or that stung his hands. On the seventh day on Zoo, while using a brown plant juice to draw a map on plastic food wrap (a pathetic left-handed effort), he began to feel distinct localized pains in his stomach. He put a finger down his throat, bringing up bits of kzin rations and pieces of the nutmeats he had swallowed after trying to chew them during breakfast. They had gone into his mouth like soft rubber capsules, and down his throat the same way.

  But they had grown tiny hair-roots in his belly, and while he watched the nasty stuff he had splashed on stone, those roots continued to grow, waving blindly. He applied himself to the task again and finally coughed up another. How many had he swallowed? Three, or four? He thought four, but saw only three, and only after smashing a dozen more of the nutshells was he satisfied that each shell held three, and only three, of the loathsome things. Not animals, perhaps, but they would eat you nonetheless. Maybe he should've named the place “Herbarium." The hell with it: “Zoo" it remained.

  On the ninth day, carrying the meat in his jacket, he began to use his right arm sparingly. That was the day he realized that he had rounded the broad curve of the lake and, if his brief memory of it from orbit was accurate, the placid lake was perhaps three times as long as it was wide. He found it possible to run, one of his few athletic specialties, and despite the wear of kzin gravity he put fourteen thousand running paces behind him before exhaustion made him gather high grasses for a bed. At a meter and a half per step, he had covered twenty-one klicks, give or take a bit, that day. Not bad in this gravity, he decided, even if the collarbone was aching again. On his abominable map, that placed him about midway down the long side of the lake. The following morning he turned west, following another stream through an open grassy plain, jogging, resting, jogging. He gathered tubers floating downstream and ate one, fearing that it would surely be deadly because it tasted like a wild strawberry.

  He followed the stream for three more days, living mostly on those delicious tubers and water, nesting warmly in thick sheaves of grass. On the next day he spied a dark mass of basalt rising to the northwest, captured two liters of water in an empty plastic bag, and risked all. It was well that he did for, late in the following day with heaving chest, he saw clouds sweeping in from the north, dragging a gray downpour as a bride drags her train. That stream far below and klicks distant was soon a broad river which would have swept him to the lake. But now he stood on a rocky escarpment, seeing the glisten of water from those crags in the distance, and knew that he would not die of thirst in the highlands. He also suspected, judging from the shredded-cotton roiling of cloud beyond those crags, that he was very near the walls of his cage.

  Even for a runner, the two-kilometer rise of those crags was daunting in high gravity. Locklear aimed for a saddleback only a thousand meters high where sheets of rain had fallen not long before, hiking beside a swollen stream until he found its source. It wasn't much as glaciers went, but he found green depths of ice filling the saddleback, shouldering up against a force wall that beggared anything he had ever seen up close. The wall was transparent, apparent to the eye only by its effects and by the eldritch blackness just beyond it. The thing was horrendously cold, seeming to cut straight across hills and crags with an inner border of ice to define this kzin compound. Locklear knew it only seemed straight because the curvature was so gradual. When he tossed a stone at it, the stone slowed abruptly and soundlessly as if encountering a meters-deep cushion, then slid downward and back to clatter onto the minuscule glacier. Uphill and down, for as far as he could see, ice rimmed the inside of the force wall. He moved nearer, staring through that invisible sponge, and saw another line of ice a klick distant. Between those ice rims lay bare basalt, as uncompromisingly primitive as the Surface of an asteroid. Most of that raw surface was so dark as to seem featureless, but reflections from ice lenses on each side dappled the dark basalt here and there. The dapples of light were crystal clear, without the usual fuzziness of objects a thousand meters away, and Locklear realized he was staring into a vacuum.

  “So visitors to Zoo can wander comfortably around with gravity polarizer platforms between the cages," he said aloud, angrily because he could see the towering masses of ponderosa pines and blue spruce in the next compound. It was an Earth compound, all right-but he could see no evidence of animals across that distance, and that made him fiercely glad for some reason. He ached to cross those impenetrable barriers, and his vision of lofty conifers blurred with his tears.

  His feet were freezing, now, and no vegetation grew as near as the frost that lined the ice rim. “You're good, but you're not perfect," he said to the builders. “You can't keep the heat in these compounds from leaking away at the rims." Hence frozen moisture and the lack of vegetation along the rim, and higher rainfall where clouds skirted that cold force wall.

  Scanning the vast panoramic are of that ice rim, Locklear noted that his prison compound had a gentle bowl shape, though some hills and crags surged up in the lowlands. Maybe using the natural contours of old craters? Or maybe you made those craters. It was an engineering project that held tremendous secrets for humankind, and it had been there for one hell of a long time. Widely spaced across that enormous bowl were spots of dramatic color, perhaps flowers. But they won't scatter much without animal vectors to help the wind disperse seeds and such. Dammit, this place wasn't finished!

  He retraced his steps downward. There was no point in making a camp in this inclement place, and with every sudden whistle of breeze now he was starting to look up, scanning for the kzin ship he knew might come at any time. He needed to find a cave, or to make one, and that would require construction tools.

  Late in the afternoon, while tying grass bundles at the edge of a low rolling plain, Locklear found wood of the kind he'd hardly dared to hope for. He simply had not expected it to grow horizontally. With a thin bark that simulated its surroundings, it lay mostly below the surface with shallow roots at intervals like bamboo. Kzinti probably would've known to seek it from the first, damn their hairy hides. The stuff-he dubbed it shamboo–grew parallel to the ground and arrow-straight, and its foliage popped up at regular intervals too. Some of its hard, hollow segments stored water, and some specimens grew thick as his thighs and ten meters long, tapering to wicked growth spines on each end. Locklear had been walking over potential hiking staffs, construction shoring, and rafts for a week without noticing. He pulled up one the size of a javelin and clipped it smooth.

  His grooming tool would do precision work, but Locklear abraded blisters on his palms fashioning an axehead from a chertlike stone common in seams where basalt crags soared from the prairie. He spent two days learning how to socket a handaxe in a shamboo handle, living mostly on tuberberries and grain from grassheads, and elevated his respect for the first tool-using creatures in the process.

  By now, Locklear's right arm felt almost as good as new, and the process of rediscovering primitive technology became a compelling pastime. He was so intent on ways to weave split shamboo filaments into cordage for a firebow, while trudging jus
t below the basalt heights, that he almost missed the most important moment of his life.

  He stepped from savannah grass onto a gritty surface that looked like other dry washes, continued for three paces, stepped up onto grassy turf again, then stopped. He recalled walking across sand-sprinkled tiles as a youth, and something in that old memory made him look back. The dry wash held wavelike patterns of grit, pebbles, and sand, but here and there were bare patches.

  And those bare patches were as black and as smooth as machine-polished obsidian.

  Locklear crammed the half-braided cord into a pocket and began to follow that dry wash up a gentle slope, toward the cleft ahead, and toward his destiny.

  His heart pounding with hope and fear, Locklear stood five meters inside the perfect arc of obsidian that formed the entrance to that cave. No runoff had ever spilled grit across the smooth broad floor inside, and he felt an irrational concern that his footsteps were defiling something perfectly pristine, clean and cold as an ice cavern. But a far, far more rational concern was the portal before him, its facing made of the same material as the floor, the opening itself four meters wide and just as high. A faint flickering luminescence, as of gossamer film stretched across the portal, gave barely enough light to see. Locklear saw his reflection in it, and wanted to laugh aloud at this ragged, skinny, barrel-chested apparition with the stubble of beard wearing stained, flight togs. And the apparition reminded him that he might not be -alone.

  He felt silly, but after clearing his throat twice he managed to call out: “Anybody home?”

  Echoes; several of them, more than this little entrance space could possibly generate. He poked his sturdy shamboo hiking staff into the gossamer film and jumped when stronger light flickered in the distance. “Maybe you just eat animal tissue," he said, with a wavering chuckle. “Well-." He took his grooming pincers and cut away the dried curl of skin around a broken blister on his palm, clipped away sizeable crescents of fingernails, tossed them at the film.
