"Air!"
"Air?" Waldron's match poised a moment, as with a slight widening of the pale blue eyes he surveyed his partner. "Why—er—what do you mean, Flint?"
"The Air Trust!"
"Eh?" And Waldron lighted his cigar.
"A monopoly of breathing privileges!"
"Ha! Ha!" Waldron's laugh was as mirthful as a grave-yard raven's croak. "Nothing to it, old man. Forget it, and stick to—"
"Of course! I might have expected as much from you!" retorted the Billionaire tartly. "You've got neither imagination nor—"
"Nor any fancy for wild-goose chases," said Waldron, easily, as he sat down in the big leather chair. "Air? Hot air, Flint! No, no, it won't do! Nothing to it nothing at all."
For a moment the Billionaire regarded him with a look of intense irritation. His thin lips moved, as though to emit some caustic answer; but he managed to keep silence. The two men looked at each other, a long minute; then Flint began again:
"Listen, now, and keep still! The idea came to me not an hour ago, this morning, looking over the city, here. We've got a finger on everything but the atmosphere, the most important thing of all. If we could control that—"
"Of course, I understand," interrupted the other, blowing a ring of smoke. "Unlimited power and so on. Looks very nice, and all. Only, it can't be done. Air's too big, too fluid, too universal. Human powers can't control it, any more than the ocean. Talk about monopolizing the Atlantic, if you will, Flint. But for heaven's sake, drop—"
"Can't be done, eh?" exclaimed Flint, warmly, sitting down on the desk-top and levelling a big-jointed forefinger at his partner. "That's what every new idea has had to meet. It's no argument! People scoffed at the idea of gas lighting when it was new. Called it 'burning smoke,' and made merry over it. That was as recently as 1832. But ten years later, gas-illumination was in full sway.
"Electric lighting met the same objection. And remember the objection to the telephone? When Congress, in 1843, granted Morse an appropriation of $30,000 to run the first telegraph line from Baltimore to Washington, one would-be humorist in that supremely intelligent body tried to introduce an amendment that part of the sum should be spent in surveying a railroad to the moon! And—"
"Can't be done, Eh?" said Flint.
"Granted," put in Waldron, "that my objection is futile, just what's your idea?"
"This!" And Flint stabbed at him with his forefinger, while the other financier regarded him with a fishily amused eye. "Every human being in this world—and there are 1,900,000,000 of them now!—is breathing, on the average, 16 cubic feet of air every hour, or about 400 a day. The total amount of oxygen actually absorbed in the 24 hours by each person, is about 17 cubic feet, or over 30 billions of cubic feet of oxygen, each day, in the entire world. Get that?"
"Well?" drawled the other.
"Don't you see?" snapped Flint, irritably. "Imagine that we extract oxygen from the air. Then—"
"You might as well try to dip up the ocean with a spoon," said Waldron, "as try to vitiate the atmosphere of the whole world, by any means whatsoever! But even if you could, what then?"
"Look here!" exclaimed the Billionaire. "It only needs a reduction of 10 per cent. in the atmospheric oxygen to make the air so bad that nobody can breathe it without discomfort and pain. Take out any more and people will die! We don't have to monopolize all the oxygen, but only a very small fraction, and the world will come gasping to us, like so many fish out of water, falling over each other to buy!"
"Possibly. But the details?"
"I haven't worked them out yet, naturally. I needn't. Herzog will take care of those. He and his staff. That's what they're for. Shall we put it up to him? What? My God, man! Think of the millions in it—the billions! The power! The—"
"Of course, of course!" interposed Waldron, calmly, eyeing his smoke. "Don't get excited, Flint. Rome wasn't built in a day. There may be something in this; possibly there may be the germ of an idea. I don't say it's impossible. It looks visionary to me; but then, as you well say, so has every new idea always looked. Let me think, now; let me think."
"Go ahead and think!" growled the Billionaire. "Think and be hanged to you! I'm going to act!"
Waldron vouchsafed no reply, but merely eyed his partner with cold interest, as though he were some biological specimen under a lens, and smoked the while.
Flint, however, turned to his telephone and pulled it toward him, over the big sheet of plate glass. Impatiently he took off the receiver and held it up to his ear.
"Hello, hello! 2438 John!" he exclaimed, in answer to the query of "Number, please?"
Silence, a moment, while Waldron slowly drew at his cigar and while the Billionaire tugged with impatience at his gray mustache.
"Hello! That you, Herzog?"
"All right. I want to see you at once. Immediately, understand?"
"Very well. And say, Herzog!"
"Bring whatever literature you have on liquid air, nitrogen extraction from the atmosphere, and so on. Understand? And come at once!"
"That's all! Good-bye!"
Smiling dourly, with satisfaction, he hung up and shoved the telephone away again, then turned to his still reflecting partner, who had now hoisted his patent leather boots to the window sill and seemed absorbed in regarding their gloss through a blue veil of nicotine.
"Herzog," announced the Billionaire, "will be here in ten minutes, and we'll get down to business."
"So?" languidly commented the immaculate Waldron. "Well, much as I'd like to flatter your astuteness, Flint, I'm bound to say you're barking up a false trail, this time! Beef, yes. Steel, yes. Railroads, steamships, coal, iron, wheat, yes. All tangible, all concrete, all susceptible of being weighed, measured, put in figures, fenced and bounded, legislated about and so on and so forth. But air—!"
He snapped his manicured fingers, to show his well-considered contempt for the Billionaire's scheme, and, throwing away his smoked-out cigar, chose a fresh one.
Flint made no reply, but with an angry grunt flung a look of scorn at the calm and placid one. Then, furtively opening his desk drawer, he once more sought the little vial and took two more pellets—an action which Waldron, without moving his head, complacently observed in a heavily-bevelled mirror that hung between the windows.
"Air," murmured Waldron, suavely. "Hot air, Flint?"
No answer, save another grunt and the slamming of the desk-drawer.
And thus, in silence, the two men, masters of the world, awaited the coming of the practical scientist, the proletarian, on whom they both, at last analysis, had to rely for most of their results.
CHAPTER III.
THE BAITING OF HERZOG.
Herzog was not long in arriving. To be summoned in haste by Isaac Flint, and to delay, was unthinkable. For eighteen years the chemist had lickspittled to the Billionaire. Keen though his mind was, his character and stamina were those of a jellyfish; and when the Master took snuff, as the saying is, Herzog never failed to sneeze.
He therefore appeared, now, in some ten minutes—a fat, rubicund, spectacled man, with a cast in his left eye and
