"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?"[Pg 632]

"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.[Pg 633] If they can fight back some I'll get mad enough to blow 'em up happy."

"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,
