“Oh, I don’t know about that,” answered Roger. “Of course, some of the airmen—especially those who get to be aces—have plenty of things happen to them. But I was talking to one of the French aviators not long ago—one who has been in the service since the war started—and he said all he had been able to do was to go up and take observations and report. There couldn’t be anything very exciting about that.”

“Oh, we’ve had excitement enough—no doubt of that,” returned Dave. “And it looks to me as if there was a good deal more excitement ahead.”

“Right you are, Dave!” cried Roger. “I’ll wager before we know it we’ll be in the very thick of it.”

“I agree with you, Roger. The Huns are certainly bombarding us for fair.”

“Did you see that tree come down a few minutes ago?” asked Phil. “It landed within a dozen feet of Captain Obray and Frank Andrews.”

“The German air scouts—those three fellows who sailed this way yesterday afternoon—must have sent in word of where we were located and what we were doing,” continued Dave. “It’s too bad our men didn’t get a chance to bring them down as they did those others.”

“I wonder what they did with that Heinrich Eberhardt?” broke in Shadow, who was working in the gang with the others.

“He is in the hospital, and I heard yesterday that he is doing very well,” answered Dave.
