"Yes, so it seems. At any rate, they notified me that this officer would be here to-day to inspect the place. It means a great deal for us if the government consents to adopt our form of machine for the naval experiments."

"To us! To you, you mean," echoed Mr. Harding, with an unpleasant laugh. "I've put enough capital into this thing now, Mortlake. I'm not the man to throw good money after bad. If we are defeated by any other make of machine at the tests I mean to sell the whole thing and at least realize what I've put into it."

Mortlake turned a little pale under his swarthy skin. He rubbed his blue chin nervously.

"Why, you wouldn't chuck us over now, Mr. Harding," he said deprecatingly. "It was at your solicitation that the plant was put up here, and I had relied on you for unlimited support. Why did you go into the manufacture of aerial machines, if you didn't mean to stick it out?"

"I had two reasons," was the rejoinder, in tones as cold as a frigid blast of wind, "one was that I thought it was certain we should capture the government contract, and the other was—well, I had a little grudge I wished to satisfy."

"But we will capture the government business. I am not afraid. There is no machine to touch the Mortlake that I know of——"

"Yes, there is," interrupted Mr. Harding; "a machine that may be able to discount it in every way."

"Nonsense! Where is such an aeroplane?" "Within a quarter of a mile from here. To be accurate, young Prescott's—you know whom I mean?"

The other nodded abstractedly.

"Well, that youth has a monoplane that has already caused me a lot of trouble." The old man's yellow skin darkened with anger, and his blue pinpoints of eyes grew flinty. "It was partly out of revenge that I decided to start up an opposition business to his. He was in the West till a few days ago, and I never dreamed that he would return till I had secured the government contract. But I am now informed—oh, I have ears everywhere in Sandy Beach—that this boy and his sister, who is in a kind of partnership with him have had the audacity to offer their machine for the government tests also."
