The officers observed the boys with new interest. The London Times had some months ago printed the experiences of a prominent English visitor to America, who had seen these young aërialists in some of their sky-scraping exhibits, and had even taken a short flight with Billy.

“We military fellows are all great for aviation—it’s a big card in this war game”—this observation from the member of staff seated nearest the general—a thoroughbred sort of man who also wore the badge of valor. “And more than that,” he added, “I have a boy of my own in the flying corps of the army.”

For a moment the men hesitated, and even made a slight movement of withdrawal. Instantly the officer seemed to have taken in the situation. The boys heard him shout:
