Dorothy tucked her fingers into his hand.

"Are you hurt anywhere, Dick?"
"Not a bit. He led me a great chase, though."
"I was scared to death until you told Martin to let the switch alone. But it was funny then! I hadn't noticed your resemblance to a
jumping-jack before. Won't you do it again sometime and let us take a movie of it?"
"That was as good as any show in town, Dick," said the lawyer, wiping his eyes, "but you must be more careful. Next time, it might not be funny at all."
"There will be no next time for this rig," replied Seaton. "This is merely to show us that our ideas are all right. The next trip will be in a full-scale, completely-equipped boat."
"It was perfectly wonderful," declared Dorothy. "I know this first flight of yours will be a turning-point or something in history. I don't pretend to understand how you did it--the sight of you standing still up there in the air made me wonder if I really were awake, even though I knew what to expect--but we wouldn't have missed it for worlds, would we, Dad?"
"No. I am very glad that we saw the first demonstration. The world has never before seen anything like it, and you two men will rank
as two of the greatest discoverers."
"Seaton will, you mean," replied Crane, uncomfortably. "You know I didn't have anything to do with it."
"It's nearly all yours," denied Seaton. "Without your ideas I would have lost myself in space in my first attempt."
"You are both wrong," said Vaneman. "You, Martin, haven't enough imagination; and you, Dick, have altogether too much, for either of you to have done this alone. The honor will be divided equally between you."
He turned to Crane as Dorothy and Seaton set out toward the house.
"What are you going to do with it, commercially? Dick, of course, hasn't thought of anything except this space-car--equally of course, you have?"
"Yes. Knowing the general nature of the power and confident that Dick would control it, I have already drawn up sketches for a power-plant installation of five hundred thousand electrical horsepower, which will enable us to sell power for less than one-tenth of a cent per kilowatt-hour and still return twenty percent annual dividends. However, the power-plant comes after the flyer."
"Why? Why not build the power-plant first, and take the pleasure trip afterward?"
"There are several reasons. The principal one is that Dick and I would rather be off exploring new worlds, while the other members of the Seaton-Crane Company, Engineers, build the power-plant."
During the talk the men had reached the house, into which the others had disappeared some time before. Upon Crane's invitation, Vaneman and his daughter stayed to dinner, and Dorothy played for awhile upon Crane's wonderful violin. The rest of the evening was spent in animated discussion of the realization of Seaton's dreams of flying without wings and beyond the supporting atmosphere. Seaton and Crane did their best to explain to the non-technical visitors how such flight was possible.
"Well, I am beginning to understand it a little," said Dorothy finally. "In plain language, it is like a big magnet or something, but different. Is that it?"
"That's it exactly," Seaton assured her.
"What are you going to call it? It isn't like anything[404] else that ever was. Already this evening you have called it a bus, a boat, a kite, a star-hound, a wagon, an aerial flivver, a sky-chariot, a space-eating wampus, and I don't know what else. Even Martin has called it a vehicle, a ship, a bird, and a shell. What is its real name?"
"I don't know. It hasn't got any that I know of. What would you suggest, Dottie?"

"I don't know what general name should be applied to them, but for this one there is only one possible name, 'The Skylark.'" "Exactly right, Dorothy," said Crane.
"Fine!" cried Seaton. "And you shall christen it, Dottie, with a big Florence flask full of absolute vacuum. 'I christen you "The Sky-
lark." BANG!'"
As the guests were leaving, at a late hour, Vaneman said:
"Oh, yes. I bought an extra Clarion as we came out. It tells a wild tale of an explosion so violent that science cannot explain it. I
don't suppose it is true, but it may make interesting reading for you two scientific sharps. Good night."
Seaton accompanied Dorothy to the car, bidding her a more intimate farewell on the way. When he returned, Crane, with an unusual expression of concern on his face, handed him the paper without a word.
"What's up, old man? Something in it?" he asked, as he took the paper. He fell silent as he read the first words, and after he had read
the entire article he said slowly:
"True, beyond a doubt. Even a Clarion reporter couldn't imagine that. It's all intra-atomic energy, all right--some poor devil trying our stunt without my horseshoe in his pocket."
"Think, Dick! Something is wrong somewhere. You know that two people did not discover X at the same time. The answer is that
somebody stole your idea, but the idea is worthless without the X. You say that the stuff is extremely rare--where did they get it?"
"That's right, Mart. I never thought of that. The stuff is extremely rare. I am supposed to know something about rare metals, and I never heard of it before--there isn't even a gap in the Periodic System in which it belongs. I would bet a hat that we have every milligram known to the world at present."
"Well, then," said the practical Crane. "We had better see whether or not we have all we started with."
Asking Shiro to bring the large bottle from the vault, he opened the living-room safe and brought forth the small vial. The large bot-tle was still nearly full, the seal upon it unbroken. The vial was apparently exactly as Seaton had left it after he had made his bars.
"Our stuff seems to be all there," said Crane. "It looks as though someone else has discovered it also." "I don't believe it," said Seaton, their positions now reversed. "It's altogether too rare."
He scanned both bottles narrowly.
"I can tell by taking the densities," he added, and ran up to the laboratory, returning with a Westphal balance in his hand. After testing both solutions he said slowly:
"Well, the mystery is solved. The large bottle has a specific gravity of 1.80, as it had when I prepared it; that in the vial reads only
1.41. Somebody has burglarized this safe and taken almost half of the solution, filling the vial up with colored water. The stuff is so
strong that I probably never would have noticed the difference." "But who could it have been?"
"Search me! But it's nothing to worry about now, anyway, because whoever it was is gone where he'll never do it again. He's taken the
solution with him, too, so that nobody else can get it."
"I wish I were sure of that, Dick. The man who tried to do the research work is undoubtedly gone--but who is back of him?" "Nobody, probably. Who would want to be?"
"To borrow your own phrase, Dick, Scott 'chirped it' when he called you 'Nobody Holme.' For a man with your brains you have the least sense of anybody I know. You know that this thing is worth, as a power project alone, thousands of millions of dollars, and that there are dozens of big concerns who would cheerfully put us both out of the way for a thousandth of that amount. The question is
20
not to find one concern who might be backing a thing like that, but to pick out the one who is backing it."
After thinking deeply for a few moments he went on:
"The idea was taken from your demonstration in the Bureau, either by an eye-witness or by someone who heard about it afterward, probably
