"You're a blinding flash and a deafening report, ace!" declared Seaton, enthusiastically. "That compa.s.s is as far ahead of my model as the _Skylark_ is ahead of Wright's first glider."

The other instruments were no less noteworthy. Dunark had adopted the Perkins telephone system, but had improved it until it was scarcely recognized and had made it capable of almost unlimited range. Even the guns--heavy rapid-firers, mounted in spherical bearings in the walls--were aimed and fired by remote control, from the board. He had devised full automatic steering controls; and meters and recorders for acceleration, velocity, distance, and flight-angle. He had perfected a system of periscopic vision, which enabled the pilot to see the entire outside surfaces of the sh.e.l.l, and to look toward any point of the heavens without interference.

"This kind of takes my eye, too, prince," Seaton said, as he seated himself, swung a large, concave disk in front of him, and experimented with levers and dials. "You certainly can't call this thing a periscope--it's no more a periscope than I am a polyp. When you look through this plate, it's better than looking out of a window--it subtends more than the angle of vision, so that you can't see anything but out-of-doors--I thought for a second I was going to fall out. What do you call 'em, Dunark?"

"Kraloto. That would be in English ... Seeing-plate? Or rather, call it 'visiplate'."

"That's a good word. Mart, take a look if you want to see a set of perfect lenses and prisms."

Crane looked into the visiplate and gasped. The vessel had disappeared--he was looking directly down upon the Earth below him!

"No trace of chromatic, spherical, or astigmatic aberration," he reported in surprise. "The refracting system is invisible--it seems as though nothing intervenes between the eye and the object. You perfected all these things since we left Osnome, Dunark? You are in a cla.s.s by yourself. I could not even copy them in less than a month, and I never could have invented them."

"I did not do it alone, by any means. The Society of Instrument-Makers, of which I am only one member, installed and tested more than a hundred systems. This one represents the best features of all the systems tried.

It will not be necessary for you to copy them. I brought along two complete duplicate sets for the _Skylark_, as well as a dozen or so of the compa.s.ses. I thought that perhaps these particular improvements might not have occurred to you, since you Terrestrials are not as familiar as we are with complex instrumental work."

Crane and Seaton spoke together.

"That was thoughtful of you, Dunark, and we appreciated it fully."

"That puts four more palms on your _Croix de Guerre_, ace. Thanks a lot."

"Say, d.i.c.k," called Dorothy, from her seat near the wall. "If we're going down to the ground, how about Sitar?"

"By lying down and not doing anything, and by staying in the vessel, where it is warm, she will be all right for the short time we must stay here," Dunark answered for his wife. "I will help all I can, but I do not know how much that will be."

"It isn't so bad lying down." Sitar agreed. "I don't like your Earth a bit, but I can stand it a little while. Anyway, I _must_ stand it, so why worry about it?"

"'At-a-girl!" cheered Seaton. "And as for you, Dunark, you'll pa.s.s the time just like Sitar does--lying down. If you do much chasing around down there where we live, you're apt to get your lights and liver twisted all out of shape--so you'll stay put, horizontal. We've got men enough around the shop to eat this cargo in three hours, let alone unload it. While they unload and load you up, we'll install the zone apparatus, put a compa.s.s on you, put one of yours on us, and then you can hop back up here where you're comfortable. Then as soon as we can get the 'Lark' ready for the trip, we'll jump up here and be on our way.

Everything clear? Cut the rope, Mart--let the old bucket drop!"

CHAPTER III

Skylark Two Sets Out

"Say, Mart, I just got conscious! It never occurred to me until just now, as Dunark left, that I'm as good an instrument-maker as Dunark is--the same one, in fact--and I've got a hunch. You know that needle on DuQuesne hasn't been working for quite a while? Well, I don't believe it's out of commission at all. I think he's gone somewhere, so far away that it can't read on him. I'm going to house it in, re-jewel it, and find out where he is."

"An excellent idea. He has even you worrying, and as for myself----"

"Worrying! That bird is simply pulling my cork! I'm so scared he'll get Dottie, that I'm running around in circles and biting myself in the small of the back. He's got a hen on, you can bet your shirt on that--what gravels me is he's aiming at the girls, not at us or the job."

"I should say that someone had aimed at you fairly accurately, judging by the number of bullets stopped lately by that arenak armor of yours. I wish that I could take some of the strain, but they are centering all their attacks upon you."

"Yes--I can't stick my nose outside our yard without somebody throwing lead at it. It's funny, too. You're more important to the power-plant than I am."

"You should know why. They are not afraid of me. While my spirit is willing enough, it was your skill and rapidity with a pistol that frustrated four attempts at abduction in as many days. It is positively uncanny, the way you explode into action. With all my practice, I didn't even have my pistol out yesterday until it was all over. And besides Prescott's guards, we had four policemen with us--detailed to 'guard'

us--because of the number of gunmen you had to kill before that!"

"It ain't practice so much, Mart--it's a gift. I've always been fast, and I react automatically. You think first, that's why you're slow.

Those cops were funny. They didn't know what it was all about until it was all over--all but calling the wagon. That was the worst yet. One of their slugs struck directly in front of my left eye--it was kinda funny, at that, seeing it splash--and I thought I was inside a boiler in a riveting shop when those machine-guns cut loose. It was hectic, all right, while it lasted. But one thing I'll tell the attentive world--we're not doing all the worrying. Very few, if any, of the gangsters they send after us are getting back. Wonder what they think when they shoot at us and we don't drop?

"But I'm afraid I'm beginning to crack, Mart," Seaton went on, his voice becoming grimly earnest. "I don't like anything about this whole mess. I don't like all four of us wearing armor all the time. I don't like living constantly under guard. I don't like all this killing. And this constant menace of losing Dorothy, if I let her out of my sight for five seconds, is driving me mad. To tell you the real truth, I'm devilishly afraid that they'll figure out something that'll work. I could grab off two women, or kill two men, if they had armor and guns enough to stock a war. I believe that DuQuesne could, too--and the rest of that bunch aren't imbeciles, either, by any means. I won't feel safe until all four of us are in the _Skylark_ and a long ways from here. I'm sure glad we're pulling out; and I don't intend to come back until I get a good line on DuQuesne. He's the bird I'm going to get, and get right--and when I get him I'll tell the c.o.c.k-eyed world he'll stay got. There won't be any two atoms of his entire carca.s.s left in the same township. I meant that promise when I gave it to him!"

"He realizes that fully. He knows that it is now definitely either his life or our own, and he is really dangerous. When he took Steel over and opened war upon us, he did it with his eyes wide open. With his ideas, he must have a monopoly of 'X' or nothing; and he knows the only possible way of getting it. However, you and I both know that he would not let either one of us live, even though we surrendered."

"You chirped it! But that guy's going to find he's started something, unless I get paralysis of the intentions. Well, how about turning up a few R. P. M.? We don't want to keep Dunark waiting too long."

"There is very little to do beyond installing the new instruments; and that is nearly done. We can finish pumping out the compa.s.s _en route_.

You have already installed every weapon of offense and defense known to either Earthly or Osnomian warfare, including those ray-generators and screens you moaned so about not having during the battle over Kondal. I believe that we have on board every article for which either of us has been able to imagine even the slightest use."

"Yes, we've got her so full of plunder that there's hardly room left for quarters. You ain't figuring on taking anybody but Shiro along, are you?"

"No. I suppose there is no real necessity for taking even him, but he wants very much to go, and may prove himself useful."

"I'll say he'll be useful. None of us really enjoys polishing bra.s.s or washing dishes--and besides, he's one star cook and an A-1 housekeeper."

The installation of the new instruments was soon completed, and while Dorothy and Margaret made last-minute preparations for departure, the men called a meeting of the managing directors and department heads of the "Seaton-Crane Co., Engineers." The chiefs gave brief reports in turn. Units Number One and Number Two of the immense new central super-power plant were in continuous operation. Number Three was almost ready to cut in. Number Four was being rushed to completion. Number Five was well under way. The research laboratory was keeping well up on its problems. Troubles were less than had been antic.i.p.ated. Financially, it was a gold mine. With no expense for boilers or fuel, and thus with a relatively small investment in plant and a very small operating cost, they were selling power at one-sixth of prevailing rates, and still profits were almost paying for all new construction. With the completion of Number Five, rates would be reduced still further.

"In short, Dad, everything's slick," remarked Seaton to Mr. Vaneman, after the others had gone.

"Yes; your plan of getting the best men possible, paying them well, and giving them complete authority and sole responsibility, has worked to perfection. I have never seen an undertaking of such size go forward so smoothly and with such fine co-operation."

"That's the way we wanted it. We hand-picked the directors, and put it up to you, strictly. You did the same to the managers. Everybody knows that his end is up to him, and him alone--so he digs in."

"However, d.i.c.k, while everything at the works is so fine, when is this other thing going to break?"

"We've won all the way so far, but I'm afraid something's about due.

That's the big reason I want to get Dot away for a while. You know what they're up to?"

"Too well," the older man answered. "Dottie or Mrs. Crane, or both. Her mother--she is telling her goodbye now--and I agree that the danger here is greater than out there."

"Danger out there? With the old can fixed the way she is now, Dot's a lot safer there than you are in bed. Your house might fall down, you know."

"You're probably right, son--I know you, and I know Martin Crane.

Together, and in the _Skylark_, I believe you invincible."

"All set, d.i.c.k?" asked Dorothy, appearing in the doorway.

"All set. You've got the dope for Prescott and everybody Dad. We may be back in six months, or we may see something to investigate, and be gone a year or so. Don't begin to lose any sleep until after we've been out--oh, say three years. We'll make it a point to be back by then."

Farewells were said; the party embarked, and _Skylark Two_ shot upward.

Seaton flipped a phone set over his head and spoke.
