“Why—father, before he died, spoke of the government, sir. He wanted the United States to have the benefit of the machine if it proved successful.”

“Bah!” sneered old Harding, scornfully, “a mere visionary dream of an inventor. Now I have a business proposition to make to you. I myself am interested in aeroplanes—or rather in their manufacture.”

“You, Mr. Harding!” Roy looked his astonishment. The last vehicle in the world one would have thought of in connection with “Old Money Grubber,” as he was sometimes called, was an aeroplane. If he had been given to such things Roy would have concluded the old man was joking.

“Yes, sir,” snapped Mr. Harding, “I am. But not directly. It’s on Fanning’s account. He tells me that he has a chance to organize a company to give aeroplane exhibitions and also to manufacture them. But he has not been able to find a suitable machine, or one that was not fully covered by patents till he saw yours in flight the other day.”

Suddenly he raised his voice:

“Fanning! Come here a minute.”

Almost immediately, through a door which Roy had not hitherto noticed, but which evidently led into an adjoining office, the figure of Simon Harding’s son appeared. To his chagrin, Roy realized that almost every word he had said to the father must have been overheard by the son.

Young Harding, who was dressed in a flashy gray suit, with trousers rolled up very high to exhibit electric blue socks of the same hue as his necktie, greeted Roy, who felt suddenly very shabby and insignificant, with a patronizing nod.

“Sorry you’re in difficulties, Roy,” he said, “but you never were a business chap even at school.”

The memory of certain monetary transactions in which young Harding had been concerned occurred to Roy. The other’s patronizing air angered him. He would have liked to make some sharp, meaning retort. But the thought of Peggy and his aunt restrained him. Roy was beginning to learn fast.
