Golden Age of Science Fiction Vol XII

by Various

  Dworn looked back from the hill crest to see it still floundering, treads furiously churning sand, struggling to fight clear of the avalanche it had carried with it. The beetle laughed full-throatedly, without rancor. This hadn't been the first nor the tightest corner he'd been in during the dangerous course of his wanderyear; and in that hard school of life you learned not to worry about danger already past.

  At another time, he might have returned to the battle in hope of capturing the additional supplies the caterpillar carried and--still more valuable booty--the chart it would have, showing the location of its other caches. But now he was in a hurry--this refueling foray had cost him a couple of hours, and the moon was already high.

  So he slipped quietly away over the ridge and set his course to the east.

  Beyond the hilly land, the terrain ironed out into level alkali flats where a vanished lake had been in the long-gone days when the earth was fertile. There he opened the throttle wide. The plain, white in the moonlight, rolled under the racing wheels at ninety and a hundred miles an hour; air whistled over the carapace....

  Impatience surged up in Dworn once more. Eagerly he pictured his forthcoming reunion with his native horde--and with Yold, his father, chief of the horde.

  Countless times in the long wanderyear--in moments when death loomed nearer than it had in the brush just past, and he despaired of surviving his testing, or in other moments, yet harder to bear, when the immensity of of the desert earth seemed about to swallow him up in his loneliness--he had grasped at that vision now soon to be real: he, Dworn, stood before the assembled horde, the year of his proving triumphantly completed, and he received before them all the proud, laconic commendation of the chief, his father.

  Hungrily he scanned the horizon ahead, saw with leaping heart that it was no longer flat. Along it a black line rose, and grew ragged as it came nearer, and became an endless line of cliffs, marching straight north and south as far as the eye could see.... The Barrier!

  Dworn recognized familiar landmarks, and altered his direction a little so as to be heading directly for the year's-end rendezvous. He knew, from childhood memories even, the outline of that vast stone rampart as it appeared by moonlight. Every year the Barrier formed the eastern limit of the beetles' annual migration, as naturally as the shore of the sea was its westward terminus. So it had been for a thousand years or more, as far back as the oldest traditions reached: generation after generation, hunting, foraging, and fighting--from the Barrier to the ocean, from the ocean to the Barrier.

  * * * * *

  To right and left the serried cliffs stretched out of sight--the edge of the world, so far as beetles knew. If you examined the contour of its rim, you could see how it corresponded point by point to the irregularities of the hilly land on its hither side. Some time, millennia ago, a great fault in the earth's crust had given way, and the unknown lands of the continental interior had been lifted as if on a platform, five hundred feet above the coastal regions. Or perhaps the coast had sunk. Legend attributed the event to the ancients' wars, when, it was said, some unimaginable weapon had cleft the continent asunder....

  Dworn perforce slowed his breakneck pace as the ground grew uneven again. He guided his machine with instinctive skill over the ascending slopes and ridges, eyes combing the moon-shadows for the first sign of his people.

  Then, a couple of miles ahead, he glimpsed lights. His heart bounded up--then sank with a prescient dismay; there was something wrong--

  The fires that winked up there--four, no, five of them, under the very rim just before the cliffs rose sheer--didn't look like campfires. They were unequally spaced, and they flared up and waned oddly by turns, glowing evilly red.

  Dworn braked the beetle to a stop on a patch of high ground, and sat straining to discern the meaning of those ominous beacons. To his imagination, rasped raw by expectation and the tension of long travel, they became red eyes of menace, warnings.... He tried the infrared viewer, but it showed no more than he could see with the naked eye. Only ghosts paraded across the screen, ghosts of the folded slopes that rose to the abrupt wall of the Barrier. Nothing seemed moving there; the whole sweep of broken and tumbled landscape appeared dead and lifeless as the moon.

  But yonder burned the fires.

  Sternly Dworn reminded himself that this night he was mature, a warrior of the proud beetle race. He thrust his fears resolutely aside; there was nothing to do but find out.

  The beetle drifted forward, but cautiously now, at a stalking pace. Dworn took advantage of the lie of the land, continually seeking cover as he advanced, to shield him from whatever eyes might be watching from the silent slopes above.

  Boulders lay ever more thickly strewn as he neared the Barrier cliffs, and he skirted patches of gravel and loose stones that would have crunched loudly under his wheels. Only occasionally, emerging into the open, he glimpsed his objective, but his sense of direction kept him bearing steadily toward the fires.

  Fifteen minutes later, the beetle's blunt nose thrusting from under a shelf of rock that would disguise its outline if anything was watching, its motor noiselessly idling, Dworn knew that his premonitions had not been in vain. He looked out upon a scene that chilled his blood.

  The burning machines, scattered for two hundred yards along the talus slope where destruction had come upon them or where they had plunged out of control, were beetles. Or they had been. Now they were wrecks, smashed, overturned, fitfully aflame.

  There was no sign of an enemy. But here was the havoc which some powerful enemy had wrought, it could not have been long ago.

  He strove to find identifying marks on the blackened hulks, but in the uncertain light could make out at first no more than the female ornaments which had graced two or three of them. Names and faces flashed through Dworn's mind; he could not know yet who had perished here, which faces he would not see again....

  It hardly occurred to him to speculate that anyone might be left alive on the scene of the debacle. For one thing, the destruction's thoroughness was too evident, and besides, in Dworn's mind, by all his background and his teaching, human and machine were inextricably one; when one perished, so did the other....

  * * * * *

  There was a dull explosion, a shower of sparks and a spreading glare as a fuel tank blew up. The flare revealed the pillar of smoke, blood-colored by reflection, that towered into the night above the scene.

  And it revealed more. For Dworn saw by that unholy light that one of the nearer beetles--capsized and burned out, its carapace burst raggedly open--it bore the golden scarab emblem which was the chief's alone.

  The sight smote Dworn like a physical blow, so that he almost cried out aloud. Somehow it had not even crossed his mind that his father Yold could have been among the slain in whatever disaster had fallen upon the beetles here.... Others might die; but his father was a pillar of strength that could not fall--the grave iron-willed chief, demanding and rewarding, for his son impartially as for all the people....

  Dworn's breath choked in his throat and his eyes stung. Fiercely he told himself that a beetle, a chief's son, did not weep.

  Not to mourn--to revenge, that was his duty. By the law of his people, the bereaved son must seek out and slay not less than three members of whatever race had done his father to death. Until then, his father's insatiate spirit would roam the deserts without rest....

  But Dworn did not even know as yet who had done this night's work.

  Suddenly, by the new blaze that still continued, he saw movement, a dull sheen of metal moving, and he froze the gesture that had been about to send him forward into the arena of death.

  The infrared was useless; by it the flickering firelight was blinding. Dworn bit his lip in anger at his own lack of precaution, and hastily twisted his sound-receptor control to maximum. The crackling of the flames swelled to a hissing roar, but through it he heard the unmistakable creaking sound of treads. Beyond the smoke moved an indistinct and monstrous shape.

 
Dworn's jaw muscles set rock-hard and his hand flashed to another control. His turret gun revolved soundlessly, and the crosshairs of the sight danced across the mirrored image of the approaching thing. His finger poised over the firing button, he braced himself to fling his machine into swift evasive action before the enemy's perhaps overwhelming firepower could reply--

  The monster lumbered slowly into the light, canted far over and traveling with an odd sidling motion along the steep rubbly slope. Great treads set far out on each side of the squat, ungainly body preserved it against overturning. Its flattened forward turret swiveled nervously from side to side, peering blackly from vision ports steel-shuttered down to squinting slits.

  And Dworn relaxed. The red hatred that had blazed up in him subsided into mere disgust; he watched the great machine's wary progress with a familiar, instinctive contempt. It was a scavenger, huge but not very formidable, drawn from afar by the fires which promised loot, salvageable scrap, perhaps even usable parts, fuel or ammunition.... It could not possibly have been responsible for the carnage; such cowardly creatures gave a wide berth to the beetle horde.

  The monster ground to a halt amid the wreckage. Then its engine bellowed with sudden power and it spun half round, one tread spraying gravel, and backed hastily away up the slope. And Dworn was aware that the noise of creaking treads had redoubled. He cast about, and saw, laboring upward from below, another big machine, closely similar to the first.

  Both scavengers came to a stop, facing one another across the fading of the fires, their unmuffled engines grumbling sullenly. Dworn watched them narrowly, expecting the shooting to begin any moment. But the scavengers' way of life was not one that encouraged reckless valor. After a long minute, a hatch-cover was lifted in the first arrival's armored back; a cautious head thrust forth, and shouted hoarsely, words clear to Dworn's amplified hearing:

  "Better go back where you came from, brother. We got here first!"

  The other scavenger's turret-hatch also swung slightly open. A different voice answered: "Don't talk foolishness, brother. We've got as much right here as you, and anyway we saw it first!"

  The first voice thickened with belligerence. "We've got the advantage of the ground on you, brother. Better back up!"

  "Oh, go smelt pebbles!" snarled the other. No doubt that was a scathing rejoinder among the scavengers.

  * * * * *

  Dworn grimaced scornfully and brought his turret-gun to bear on an outcropping midway between the disputants. Either of them outweighed the little beetle twenty times over--but at this juncture a single unexpected shot would probably send both of them scuttling for cover--

  But he halted again on the verge of firing. For he had not stopped listening, and now his trained ears picked out another, an unfamiliar sound from the background of noises.

  It was a queer rattle and scurry, mingled with a high-pitched buzz that could only come from a number of small but high-speed motors. It was not a sound the exact like of which Dworn remembered having heard before. He went rigid, staring, as the sound's source came into view.

  A column of little machines--lighter even than a beetle, and more elongated--advancing in single file, multiple wheels swerving in the leader's tracks as the column wound nearer along the mountainside. As the firelight fell on them they gleamed with the mild sheen of aluminum. Round vision-ports stared glassily, and turbines buzzed feverishly shrill.

  With astonishing bravado, the flimsy little vehicles, one behind another, came parading onto the wreck-strewn slope.

  And what was more startling still--no two of them were alike. The leader mounted a winch in plain view; behind came another machine fitted with oddly-shaped grappling claws, and next one bearing a mysterious device terminating in front in a sort of flexible trunk.... Strangely, too, they didn't seem to carry any armament--no snouting guns, no flame or gas projectors.

  Despite that fact or perhaps because of it, something sounded an alarm deep in Dworn's mind.

  Their diversity itself was uncanny, that was certain. In all Dworn's experience, machines were the work of races whose traditions of construction, handed down from forgotten antiquity, were as fixed and unvarying as the biological heredity that made one race light-haired, another dark....

  A hatch-cover clanged shut, and another. The squabbling scavengers had finally noticed the appearance of outside competition. The one upslope raced its engine uncertainly, swung round to face the buzzing invaders, hesitated.

  The newcomers, for their part, seemed oblivious to the scavengers' presence. Their column began dispersing. A grapple-armed machine laid hold on one of the wrecked beetles and, whining with effort, sought to drag it to leveler ground. A second, following, spat a burst of sparks and extended a gleaming arm tipped by the singing blue radiance of a cutting torch.

  The first-come scavenger growled throatily and lumbered toward the interlopers, plainly taking heart from their air of harmless stupidity. Behind it, the other scavenger came clattering up the slope to its fellow's aid.

  Flame bloomed thunderously from the muzzle of the first one's forward gun. The machine with the torch was flung bodily into the air and went rolling and bouncing down the hill, wheels futilely spinning. The gun roared again, and the exploding shell tore open a flimsy aluminum body from nose to tail. Motors whirred frantically as the pygmies scattered before the charging behemoth. One of them darted witlessly right under the huge treads, and disappeared with a brief screech of crumpling metal.

  * * * * *

  The fight was over as quickly as it had begun. The scavenger wheeled, snorting, and fired one more shot into the dark after its routed opponents....

  Dworn muttered an imprecation under his breath. No chance of frightening the scavengers off now that their blood was up and their differences forgotten; and a lone beetle could scarcely stand up to two of them in a knock down fight. To rush in now would be suicidal.

  He gave up the idea of investigating the scene of disaster more closely, and backed stealthily away, keeping to the cover of the rocks. At a safe distance he began circling round, downslope.

  What he could and must do now was to locate what was left of his native horde. It had numbered about fifty when he had departed for his wanderyear; a dozen, perhaps more, had died on the mountain tonight. He must seek out the survivors, and help plan retaliation against whatever enemy had dealt them this terrible blow.

  Yet something else nagged at his mind, until he halted to gaze achingly once more toward the glowing embers up there, where the scavengers now clanked to and fro about their business.

  Dworn recognized that what bothered him was the puzzle of the unidentified little machines that had turned up on the battlefield only to be sent packing. During his yearlong solitary struggle to survive, he had developed an extra sense or two--and in the queerly confident behavior of those buzzing strangers he had scented danger, a trap....

  So it happened that he was still looking on at the moment when the trap was sprung.

  A star, it seemed, fell almost vertically from the zenith, falling and expanding with the uncanny silence of flight faster than sound. The scavengers had no time to act. Dworn caught one faint glimpse of a winged shape against the sky, limned by the flashes that stabbed from it as it leveled out of its terrific dive.

  One scavenger shuddered with the force of a heavy explosion somewhere within it, and subsided, smoking. The other too staggered under crippling impacts, but ground somehow into motion, spinning and sliding crazily down the gravel slope. Then, as the first attacker's shock-wave made the very earth tremble, a second and a third plunged from the black heights, and as the last one rose screeching from its swoop the whole lower face of the hillside boomed into a holocaust of flame and oily smoke. The fleeing scavenger was gone, enveloped somewhere in an acre of fiery hell.

  Dworn, two hundred yards away, felt a searing breath of heat, and with a great effort controlled the impulse to whirl round and race for opener ground. He sat still, hands cramped sweating o
n the beetle's controls, while the sky whistled vindictively with the flight of things that circled in search of further targets.

  When, after a seeming eon, their screaming died away, he released held breath in a long sigh. He found himself trembling with reaction. Still he didn't stir. He was ransacking his memory for something he should be able to recall but which eluded him--a myth, perhaps, heard as a child beside the campfires of the horde--

  The old men would know; Yold would have known. At thought of his father, the grief and fury rose up again in Dworn, and this time he knew the object of his vengeful anger. There was small doubt now in his mind that those flying machines which struck so swiftly and so murderously had been the beetles' attackers.

  But he didn't know what they were. He knew, of course, about the machines called hornets, which could fly and strike at fearful speeds like that, outracing sound. But the hornets flew only in daylight, and made no trouble for the nocturnal race of beetles. These--were something else.

  And more--between the deadly night-fliers and the harmless-looking aluminum crawlers he had seen, Dworn sensed some connection, some unnatured symbiosis. He had heard vague rumors about such arrangements, but had half-discounted them; any of the peoples whom he knew at first hand would have scorned to enter into alliance with an alien species.

  Lastly, he realized bitterly, he didn't even know where the enemy's lair, their base on the ground, might be....

  * * * * *

  The moon stood high now. But the Barrier, close at hand now, rose like an immense black wall, folded in shadows, revealing no secrets--walling off the world the beetles knew from the unknown beyond. Involuntarily Dworn shivered. He couldn't be sure--but it seemed to him that the destroyers had come from over the Barrier and had flown back there.

  He set his machine in cautious motion again and stole along, making northward and keeping close to the Barrier. It occurred to him that the beetle horde, routed and fleeing, might well have hugged the cliffs for protection against flying foes.
