"He no longer lodges with my friend, the warden," went on Waller. "In fact, to tell the whole truth, there was a jail delivery week ago, which has been kept secret up to now. The warden says he was just sending out the news when I called him. Jules and two other convicts managed to break away; and while the others have been recaptured, Jules is still at large!"

CHAPTER X

IN PARTNERSHIP WITH THE CHIEF

Frank breathed a little faster than ordinary but there was little else to indicate that he had heard startling news.

"And now, Frank, don't forget that you promised to take me in on this," the head of the local force went on, persuasively. "You remember that we stood by you at that other time, and rounded Jules up in great shape. Seems like we might have to do it again, sort of history repeating itself. How did you know about it?"

"I didn't, sir, and that's the queer part it," replied the boy.

"Then you suspected something of the sort—did you run across Jules on the road; or has he been trying to steal your aeroplane again?" continued Chief Waller.

"Neither one nor the other, sir. But some unknown person fired a rifle at our biplane today, when we were passing over those woods near the old shack. The bullet came within a few feet of us, as I can show you, for it passed through both planes. That looks as if the scamp meant to do us real harm. And it set me to thinking and guessing, with the result that I made up my mind to come to you, and find out if Jules was still safe behind the bars."

"Well, this is something I'll have to look into," bustled the stout Chief, as he pushed back his chair. "Up in the Powell woods, you said; that makes it look as if it must be him; because he hid there before, you know."

"If it had happened anywhere else, I guess I'd never have thought about Jules, sir," Frank candidly admitted. "But you see, we were just talking about our other adventure when the shot came; and somehow, it was natural to connect the two. But it seems foolish for him to come back to the old place again."
