Loaded until her outer skin almost bulged with tightly packed bars of uranium and equipped to meet any emergency of which the combined efforts of the mightiest intellects of Norlamin could foresee even the slightest possibility, Skylark Three lay quiescent. Quiescent, but surcharged with power, she seemed to Seaton's tense mind to share his own eagerness to be off; seemed to be motionlessly straining at her neutral controls in a futile endeavor to leave that unnatural and unpleasant environment of atmosphere and of material substance, to soar outward into absolute zero of temperature and pressure, into the pure and undefiled ether which was her natural and familiar medium. The five human beings were grouped near an open door of their cruiser; before them were the ancient scientists, who for so many days had been laboring with them in their attempt to crush the monstrous race which was threatening the Universe. With the elders were the Terrestrials' many friends from the Country of Youth, and surrounding the immense vessel in a throng covering an area to be measured only in square miles were massed myriads of Norlaminians. From their tasks everywhere had come the mental laborers; the Country of Youth had been left depopulated; even those who, their lifework done, had betaken themselves to the placid Nirvana of the Country of Age, returned briefly to the Country of Study to speed upon its way that stupendous Ship of Peace. The majestic Fodan, Chief of the Five, was concluding his address: "And may the Unknowable Force direct your minor forces to a successful conclusion of your task. If, upon the other hand, it should by some unforeseen chance be graven upon the Sphere that you are to pass in this supreme venture, you may pass in all tranquillity, for the massed intellect of our entire race is here supporting me in my solemn affirmation that the Fenachrone shall not be allowed to prevail. In the name of all Norlamin, I bid you farewell." Skylark Three is launched. Crane spoke briefly in reply and the little group of Earthly wanderers stepped into the elevator. As they sped upward toward the control room, door after door shot into place behind them, establishing a manifold seal. Seaton's hand played over the controls and the great cruiser of the void tilted slowly upward until its narrow prow pointed almost directly into the zenith. Then, very slowly at first, the unimaginable mass of the vessel floated lightly upward, with a slowly increasing velocity. Faster and faster she flew—out beyond measurable atmosphere, out beyond the outermost limits of the green system. Finally, in interstellar space, Seaton threw out super-powered detector and repelling screens, anchored himself at the driving console with a force, set the power control at "molecular" so that the propulsive force affected alike every molecule of the vessel and its contents, and, all sense of weight and acceleration lost, he threw in the plunger switch which released every iota of the theoretically possible power of the driving mass of uranium. Staring intently into the visiplate, he corrected their course from time to time by minute fractions of a second of arc; then, satisfied at last, he set the automatic forces which would guide them, temporarily out of their course, around any obstacles, such as the uncounted thousands of solar systems lying in or near their path. He then removed the restraining forces from his body and legs, and with a small pencil of force wafted himself over to Crane and the two women. "Well, bunch," he stated, matter-of-fact, "we're on our way. We'll be this way for some time, so we might as well get used to it. Any little thing you want to talk over?" "How long will it take us to catch 'em?" asked Dorothy "Traveling this way isn't half as much fun as it is when you let us have some weight to hold us down." "Hard to tell exactly, Dottie. If we had precisely four times their acceleration and had started from the same place, we would of course overtake them in just the number of days they had the start of us, since the distance covered at any constant positive acceleration is proportional to the square of the time elapsed. However, there are several complicating factors in the actual situation. We started out not only twenty-nine days behind them, but also a matter of five hundred thousand light-years of distance. It will take us quite a while to get to their starting-point. I can't tell even that very close, as we will probably have to reduce this acceleration before we get out of the Galaxy, in order to give detectors and repellers time to act on stars and other loose impediments. Powerful as those screens are and fast as they work, there is a limit to the velocity we can use here in this crowded Galaxy. Outside it, in free space, of course we can open her up again. Then, too, our acceleration is not exactly four times theirs, only three point nine one eight six. On the other hand, we don't have to catch them to go to work on them. We can operate very nicely at five thousand light-centuries. So there you are—it'll probably be somewhere between thirty-nine and forty-one days, but it may be a day or so more or less." "How do you know they are using copper?" asked Margaret. "Maybe their scientists stored up some uranium and know how to use it." "Nope, that's out like a light. First, Mart and I saw only copper bars in their ship. Second, copper is the most efficient metal found in quantity upon their planet. Third, even if they had uranium or any metal of its class, they couldn't use it without a complete knowledge of, and ability to handle, the fourth and fifth orders of rays." "It is your opinion, then, that destroying this last Fenachrone vessel is to prove as simple a matter as did the destruction of the others?" Crane queried, pointedly. "Hm-m-m. Never thought about it from that angle at all, Mart.... You're still the ground-and-lofty thinker of the outfit, ain't you? Now that you mention it, though, we may find that the Last of the Mohicans ain't entirely toothless, at that. But say, Mart, how come I'm as wild and cock-eyed as I ever was? Rovol's a slow and thoughtful old codger, and with his accumulation of knowledge it looks like I'd be the same way." "Far from it," Crane replied. "Your nature and mine remain unchanged. Temperament is a basic trait of heredity, and is neither affected nor acquired by increase of knowledge. You acquired knowledge from Rovol, Drasnik, and others, as did I—but you are still the flashing genius and I am still your balance wheel. As for Fenachrone toothlessness: now that you have considered it, what is your opinion?" "Hard to say. They didn't know how to control the fifth order rays, or they wouldn't have run. They've got real brains, though, and they'll have something like seventy days to work on the problem. While it doesn't stand to reason that they could find out much in seventy days, still they may have had a set-up of instruments on their detectors that would have enabled them to analyze our fields and thus compute the structure of the secondary projector we used there. If so, it wouldn't take them long to find out enough to give us plenty of grief—but I don't really believe that they knew enough. I don't quite know what to think. They may be easy and they may not; but, easy or hard to get, we're loaded for bear and I'm plenty sure that we'll pull their corks." "So am I, really, but we must consider every contingency. We know that they had at least a detector of fifth-order rays...." "And if they did have an analytical detector," Seaton interrupted, "they'll probably slap a ray on us as soon as we stick our nose out of the Galaxy!" "They may—and even though I do not believe that there is any probability of them actually doing it, it will be well to be armed against the possibility." "Right, old top—we'll do that little thing!" Uneventful days passed, and true to Seaton's calculations, the awful acceleration with which they had started out could not be maintained. A few days before the edge of the Galaxy was reached, it became necessary to cut off the molecular drive, and to proceed with an acceleration equal only to that of gravitation at the surface of the Earth. Tired of weightlessness and its attendant discomforts to everyday life, the travelers enjoyed the interlude immensely, but it was all too short—too soon the stars thinned out ahead of "Three's" needle prow. As soon as the way ahead of them was clear, Seaton again put on the maximum power of his terrific bars and, held securely at the console, set up a long and involved integral. Ready to transfer the blended and assembled forces to a plunger, he stayed his hand, thought a moment, and turned to Crane. "Want some advice, Mart. I'd thought of setting up three or four courses of five-ply screen on the board—a detector screen on the outside of each course, next to it a repeller, then a full-coverage ether-ray screen, then a zone of force, and a full-coverage fifth-order ray-screen as a liner. Then, with them all set up on the board, but not out, throw out a wide detector. That detector would react upon the board at impact with anything hostile, and automatically throw out the courses it found necessary." "That sounds like ample protection, but I am not enough of a ray-specialist to pass an opinion. Upon what point are you doubtful?" "About leaving them on the board. The only trouble is that the reaction isn't absolutely instantaneous. Even fifth-order rays would require a millionth of a second or so to set the courses. Now if they were using ether waves, that would be lots of time to block them, but if they should happen to have fifth-order stuff it'd get here the same time our own detector-impulse would, and it's just barely conceivable that they might give us a nasty jolt before the defenses went out. Nope, I'm developing a cautious streak myself now, when I take time to do it. We've got lots of uranium, and I'm going to put one course out." "You cannot put everything out, can you?" "Not quite, but pretty nearly, I'll leave a hole in the ether screen to pass visible light—no, I won't either. You folks can see just as well, even on the direct-vision wall plates, with light heterodyned on the fifth, so we'll close all ether bands, absolutely. All we'll have to leave open will be the one extremely narrow band upon which our projector is operating, and I'll protect that with a detector screen. Also, I'm going to send out all four courses, instead of only one—then I'll know we're all right." "Suppose they find our one band, narrow as it is? Of course, if that were shut off automatically by the detector, we'd be safe; but would we not be out of control?" "Not necessarily—I see you didn't get quite all this stuff over the educator. The other projector worked that way, on one fixed band out of the nine thousand odd possible. But this one is an ultra-projector, an improvement invented at the last minute. Its carrier wave can be shifted at will from one band of the fifth order to any other one; and I'll bet a hat that's one thing the Fenachrone haven't got! Any other suggestions?... all right, let's get busy!" A single light, quick-acting detector was sent out ahead of four courses of five-ply screen, then Seaton's fingers again played over the keys, fabricating a detector screen so tenuous that it would react to nothing weaker than a copper power bar in full operation and with so nearly absolute zero resistance that it could be driven at the full velocity of his ultra-projector. Then, while Crane watched the instruments closely and while Dorothy and Margaret watched the faces of their husbands with only mild interest, Seaton drove home the plunger that sent that prodigious and ever-widening fan ahead of them with a velocity unthinkable millions of times that of light. For five minutes, until that far-flung screen had gone as far as it could be thrown by the utmost power of the uranium bar, the two men stared at the unresponsive instruments, then Seaton shrugged his shoulders. "I had a hunch," he remarked with a grin. "They didn't wait for us a second. 'I don't care for some,' says they, 'I've already had any.' They're running in a straight line, with full power on, and don't intend to stop or slow down." "How do you know?" asked Dorothy. "By the distance? How far away are they?" "I know, Red-Top, by what I didn't find out with that screen I just put out. It didn't reach them, and it went so far that the distance is absolutely meaningless, even expressed in parsecs. Well, a stern chase is proverbially a long chase, and I guess this one isn't going to be any exception." Every eight hours Seaton launched his all-embracing ultra-detector, but day after day passed and the instruments remained motionless after each cast of that gigantic net. For several days the Galaxy behind them had been dwindling from a mass of stars down to a huge bright lens; down to a small, faint lens; down to a faintly luminous patch. At the previous cast of the detector it had still been visible as a barely-perceptible point of light in the highest telescopic power of the visiplate. Now, as Dorothy and Seaton, alone in the control room, stared into that visiplate, everything was blank and black; sheer, indescribable blackness; the utter and absolute absence of everything visible or tangible. "This is awful, Dick.... It's just too darn horrible. It simply scares me pea-green!" she shuddered as she drew herself to him, and he swept both his mighty arms around her in a soul-satisfying embrace. "'Sall right, darling. That stuff out there'd scare anybody—I'm scared purple myself. It isn't in any finite mind to understand anything infinite or absolute. There's one redeeming feature, though, cuddle-pup—we're together." "You chirped it, lover!" Dorothy returned his caresses with all her old-time fervor and enthusiasm. "I feel lots better now. If it gets to you that way, too, I know it's perfectly normal—I was beginning to think maybe I was yellow or something ... but maybe you're kidding me?" she held him off at arm's length, looking deep into his eyes: then, reassured, went back-into his arms. "Nope, you feel it, too," and her glorious auburn head found its natural resting-place in the curve of his mighty shoulder. "Yellow!... You?" Seaton pressed his wife closer still! and laughed aloud. "Maybe—but so is picric acid; so is nitroglycerin; and so is pure gold." "Flatterer!" Her low, entrancing chuckle bubbled over. "But you know I just revel in it. I'll kiss you for that!" "It is awfully lonesome out here, without even a star to look at," she went on, after a time, then laughed again. "If the Cranes and Shiro weren't along, we'd be really 'alone at last,' wouldn't we?" "I'll say we would! But that reminds me of something. According to my figures, we might have been able to detect the Fenachrone on the last test, but we didn't. Think I'll try 'em again before we turn in." Once more he flung out that tenuous net of force, and as it reached the extreme limit of its travel, the needle of the micro-ammeter flickered slightly, barely moving off its zero mark. "Whee! Whoopee!" he yelled. "Mart, we're on 'em!" "Close?" demanded Crane, hurrying into the control room upon his beam. "Anything but. Barely touched 'em—current something less than a thousandth of a micro-ampere on a million to one step-up. However, it proves our ideas are O. K." The next day—Skylark III was running on Eastern Standard Time, of the Terrestrial United States of America—the two mathematicians covered sheet after sheet of paper with computations and curves. After checking and rechecking the figures, Seaton shut off the power, released the molecular drive, and applied acceleration of twenty-nine point six oh two feet per second; and five human beings breathed as one a profound sigh of relief as an almost-normal force of gravitation was restored to them. "Why the let-up?" asked Dorothy. "They're an awful long ways off yet, aren't they? Why not hurry up and catch them?" "Because we're going infinitely faster than they are now. If we kept up full acceleration, we'd pass them so fast that we couldn't fight them at all. This way, we'll still be going a lot faster than they are when we get close to them, but not enough faster to keep us from maneuvering relatively to their vessel, if things should go that far. Guess I'll take another reading on 'em." "I do not believe that I should," Crane suggested, thoughtfully. "After all, they may have perfected their instruments, and yet may not have detected that extremely light touch of our ray last night. If so, why put them on guard?" "They're probably on guard, all right, without having to be put there—but it's a sound idea, anyway. Along the same line I'll release the fifth-order screens, with the fastest possible detector on guard. We're just about within reach of a light copper-driven ray right now, but it's a cinch they can't send anything heavy this far, and if they think we're overconfident, so much the better." "There," he continued, after a few minutes at the keyboard. "All set. If they put a detector on us, I've got a force set to make a noise like a New York City fire siren. If pressed, I'd reluctantly admit that in my opinion we're carrying caution to a point ten thousand degrees below the absolute zero of sanity. I'll bet my shirt that we don't hear a yip out of them before we touch 'em off. Furthermore...." The rest of his sentence was lost in a crescendo bellow of sound. Seaton, still at the controls, shut off the noise, studied his meters carefully, and turned around to Crane with a grin. "You win the shirt, Mart. I'll give it to you next Wednesday, when my other one comes back from the laundry. It's a fifth-order detector ray, coming in beautifully on band forty-seven fifty, right in the middle of the order." "Aren't you going to put a ray on 'em?" asked Dorothy in surprise. "Nope—what's the use? I can read theirs as well as I could one of my own. Maybe they know that too—if they don't we'll let 'em think we're coming along, as innocent as Mary's little lamb, so I'll let their ray stay on us. It's too thin to carry anything, and if they thicken it up much I've got an axe set to chop it off." Seaton whistled a merry lilting refrain as his fingers played over the stops and keys. "Why, Dick, you seem actually pleased about it." Margaret was plainly ill at ease. "Sure am. I never did like to drown baby kittens, and it kinda goes against the grain to stab a guy in the back, when he ain't even looking, even if he is a Fenachrone. "But suppose they fight back too hard?" "They can't—the worst that can possibly happen is that we can't lick them. They certainly can't lick us, because we can outrun 'em. If we can't get 'em alone, we'll beat it back to Norlamin and bring up re-enforcements." "I am not so sure," Crane spoke slowly. "There is, I believe, a theoretical possibility that sixth-order rays exist. Would an extension of the methods of detection of fifth-order rays reveal them?" "Sixth? Sweet spirits of niter! Nobody knows anything about them. However, I've had one surprise already, so maybe your suggestion isn't as crazy as it sounds. We've got three or four days yet before either side can send anything except on the sixth, so I'll find out what I can do." He flew at the task, and for the next three days could hardly be torn from it for rest; but "O. K., Mart," he finally announced. "They exist, all right, and I can detect 'em. Look here," and he pointed to a tiny receiver, upon which a small lamp flared in brilliant scarlet light. "Are they sending them?" "No, fortunately. They're coming from our bar. See, it shines blue when I put a grounded shield between it and the bar, and stays blue when I attach it to their detector ray." "Can you direct them?" "Not a chance in the world. That means a lifetime, probably many lifetimes, of research, unless somebody uses a fairly complete pattern of them close enough to this detector so that I can analyze it. 'Sa good deal like calculus in that respect. It took thousands of years to get it in the first place, but it's easy when somebody that already knows it shows you how it goes." "The Fenachrone learned to direct fifth-order rays so quickly, then, by an analysis of our fifth-order projector there?" "Our secondary projector, yes. They must have had some neutronium in stock, too—but it would have been funny if they hadn't, at that—they've had intra-atomic power for ages." Silent and grim, he seated himself at the console, and for an hour he wove an intricate pattern of forces upon the inexhaustible supply of keys afforded by the ultra-projector before he once touched a plunger. "What are you doing? I followed you for a few hundred steps, but could go no farther." "Merely a little safety-first stuff. In case they should send any real pattern of sixth-order rays this set-up will analyze it, record the complete analysis, throw out a screen against every frequency of the pattern, throw on the molecular drive, and pull us back toward the galaxy at full acceleration, while switching the frequency of our carrier wave a thousand times a second, to keep them from shooting a hot one through our open band. It'll do it all in about a millionth of a second, too—I want to get us all back alive if possible! Hm—m. They've shut off their ray—they know we've tapped onto it. Well, war's declared now—we'll see what we can see." Transferring the assembled beam to a plunger, he sent out a secondary projector toward the Fenachrone vessel, as fast as it could be driven, close behind a widespread detector net. He soon found the enemy cruiser, but so immense was the distance that it was impossible to hold the projection anywhere in its neighborhood. They flashed beyond it and through it and upon all sides of it, but the utmost delicacy of the controls would not permit of holding even upon the immense bulk of the vessel, to say nothing of holding upon such a relatively tiny object as the power bar. As they flashed repeatedly through the warship, they saw piecemeal and sketchily her formidable armament and the hundreds of men of her crew, each man at battle station at the controls of some frightful engine of destruction. Suddenly they were cut off as a screen closed behind them—the Earth-men felt an instant of unreasoning terror as it seemed that one-half of their peculiar dual personalities vanished utterly. Seaton laughed. "That was a funny sensation, wasn't it? It just means that they've climbed a tree and pulled the tree up after them." "I do not like the odds, Dick," Crane's face was grave. "They have many hundreds of men, all trained; and we are only two. Yes, only one, for I count for nothing at those controls." "All the better, Mart. This board more than makes up the difference. They've got a lot of stuff, of course, but they haven't got anything like this control system. Their captain's got to issue orders, whereas I've got everything right under my hands. Not so uneven as they think!" Within battle range at last, Seaton hurled his utmost concentration of direct forces, under the impact of which three courses of Fenachrone defensive screen flared through the ultra-violet and went black. There the massed direct attack was stopped—at what cost the enemy alone knew—and the Fenachrone countered instantly and in a manner totally unexpected. Through the narrow slit in the fifth-order screen through which Seaton was operating, in the bare one-thousandth of a second that it was open, so exactly synchronized and timed that the screens did not even glow as it went through the narrow opening, a gigantic beam of heterodyned force struck full upon the bow of the Skylark, near the sharply-pointed prow, and the stubborn metal instantly flared blinding white and exploded outward in puffs of incandescent gas under the awful power of that Titanic thrust. Through four successive skins of inoson, the theoretical ultimate of possible strength, toughness, and resistance, that frightful beam drove before the automatically-reacting detector closed the slit and the impregnable defensive screens, driven by their mighty uranium bars, flared into incandescent defense. Driven as they were, they held, and the Fenachrone, finding that particular attack useless, shut off their power. "Wow! They sure have got something!" Seaton exclaimed in unfeigned admiration. "They sure gave us a solid kick that time! We will now take time out for repairs. Also, I'm going to cut our slit down to a width of one kilocycle, if I can possibly figure out a way of working on that narrow a band, and I'm going to step up our shifting speed to a hundred thousand. It's a good thing they built this ship of ours in a lot of layers—if that'd go through the interior we would have been punctured for fair. You might weld up those holes, Mart, while I see what I can do here." Then Seaton noticed the women, white and trembling, upon a seat. "'Smatter? Cheer up, kids, you ain't seen nothing yet. That was just a couple of little preliminary love-taps, like two boxers kinda feeling each other out in the first ten seconds of the first round." "Preliminary love-taps!" repeated Dorothy, looking into Seaton's eyes and being reassured by the serene confidence she read there. "But they hit us, and hurt us badly—why, there's a hole in our Skylark as big as a house, and it goes through four or five layers!" "Yes, but we're not hurt a bit. They're easily fixed, and we've lost nothing but a few tons of inoson and uranium. We've got lots of spare metal. I don't know what I did to him, any more than he knows what he did to us, but I'll bet my other shirt that he knows he's been nudged!" Repairs completed and the changes made in the method of projection, Seaton actuated the rapidly-shifting slit and peered through it at the enemy vessel. Finding their screens still up, he directed a complete-coverage attack upon them with four bars, while with the entire massed power of the remaining generators concentrated into one frequency, he shifted that frequency up and down the spectrum, probing, probing, ever probing with that gigantic beam of intolerable energy—feeling for some crack, however slight, into which he could insert that searing sheet of concentrated destruction. Although much of the available power of the Fenachrone was perforce devoted to repelling the continuous attack of the Terrestrials, they maintained an equally continuous attack offensive, and in spite of the narrowness of the open slit and the rapidity with which that slit was changing from frequency to frequency, enough of the frightful forces came through to keep the ultra-powered defensive screens radiating far into the violet—and, the utmost power of the refrigerating system proving absolutely useless against the concentrated beams being employed, mass after mass of inoson was literally blown from the outer and secondary skins of the Skylark by the comparatively tiny jets of force that leaked through the momentarily open slit from time to time, as exact synchronization was accidentally obtained. Seaton, grimly watching his instruments, glanced at Crane, who, calm but watchful at his console, was repairing the damage as fast as it was done. "They're sending more stuff, Mart, and it's getting hotter to handle. That means they're building more projectors. We can play that game, too. They're using up their fuel reserves fast; but we're bigger than they are, carry more metal, and it's more efficient metal, too. Only one way out of it, I guess—what say we put in enough generators to smother them down by brute force, no matter how much power it takes?" "Why don't you use some of those awful copper shells? Or aren't we close enough yet?" Dorothy's low voice came clearly, so utterly silent was that frightful combat. "Close! We're still better than two hundred thousand light-years apart! There may have been longer-range battles than this somewhere in the Universe, but I doubt it. And as for copper, even if we could get it to them, it'd be just like so many candy kisses compared to the stuff we're both using. Dear girl, there are fields of force extending for thousands of miles from each of these vessels beside which the exact center of the biggest lightning flash you ever saw would be a dead area!" He set up a series of integrals and, machine after machine, in a space left vacant by the rapidly-vanishing store of uranium, there appeared inside the fourth skin There was a sudden cessation of all resistance, and those Titanic forces, all directed inward, converged upon a point with a power behind which there was the inconceivable energy of four hundred thousand tons of uranium, being disintegrated at the highest possible rate, short of instant disruption. In that same instant of collapse, the enormous mass of power-copper in the Fenachrone cruiser and the vessel's every atom, alike of structure and contents, also exploded into pure energy at the touch of that unimaginable field of force. In that awful moment before Seaton could shut off his power it seemed to him that space itself must be obliterated by the very concentration of the unknowable and incalculable forces there unleashed—must be swallowed up and lost in the utterly indescribable brilliance of the field of radiance driven to a distance of millions upon incandescent millions of miles from the place where the last representatives of the monstrous civilization of the Fenachrone had made their last stand against the forces of Universal Peace. |
