"Six weeks. I wrote reminding them of my visit."

"Gosh! Six weeks! Then, what happened?"

"They sent a formal acknowledgment—the matter was having their consideration."

Andrew Provost leaped from his chair and stood facing Joe, biting his cigar fiercely. "You mean to tell me that that's the treatment you received? That I might expect the same to-morrow if I went to the War Office with a brilliant invention?" he demanded hotly. "Do you mean to say that I'd as likely as not be interviewed by a fellow who knew next to nothing about the matter, and that weeks would elapse before I heard from 'em again, and then only after sending 'em a reminder?"

Joe laughed. "That was my experience," he said. "I dare say others meet with the same. Tantalizing, eh, Uncle?"

"Tantalizing be hanged! If that's the sort of thing that happens, then the sooner the crowd inside that office is hauled out and booted the better. Guess live men are wanted—folks who can earn their pay—not dolls and dullards. But let's leave 'em. Tell me about the ship—go on."

"She was wrecked; a violent gale sprang up."

"Ah! Usual thing. That's the weak part about those Zeppelins," said Andrew. "They're unmanageable in a wind. A half-dozen and more of them have been wrecked; so you suffered in the same way."

"No! The gale wrecked my hangar; it was flimsily put together. That was the fault of having small funds. As to Zeppelins, I know that they have that particular weakness. Wait till you see my designs. I'm not afraid of a gale, and can manœuvre into my hangar when gusts are blowing at fifty miles an hour. Fact, Uncle! You'll see when we've finished."

Andrew Provost strode backwards and forwards before the wide-open window of the hotel. He was thinking deeply, and more than once he cast a shrewd, sharp glance at his nephew. This long-headed man was a little uneasy. And who can blame him? For, in the first place, solely on the strength of Joe's assertion, and because Mr. Reitberg had riled him, he had taken up a challenge. And now he heard his nephew declare that a fifty-mile gale was of no consequence, though to a Zeppelin airship it would prove easily disastrous. Was Joe romancing? Or was he so carried away by this work of his that his imagination made successes where they did not exist?
