nough of that funny business, as you call it. They even fired at
us. Depend on it, Andy, they won't follow us very far next time."

And Andy, seeing the way his chum's mouth was firmly set, made up his
mind that Frank had reached the end of his patience. Contented with the
prospects for the morrow he therefore lay down to get some sleep.

"I say, Frank," he called out presently.

"Well, what now?" asked the one on guard, who had possession of the
rifle and had taken up his position so that he could have a clear view
of the open space all about the camp.

"If one of the prowlers tries to drag me off, remember I've got my leg
tied to this stake I knocked into the ground. While he's tugging you can
have a bully good chance to knock him over, see?"

"All right," grinned Frank. "I'll remember. But let out a whoop if you

Time passed on.

It seemed as though a thousand things flitted through the active mind of
the young aviator as he thus stood guard over the camp. Once again he
was back in good old Bloomsbury, where he had spent so many happy
days. He could see the faces of his boyhood friends, Larry, Elephant and
others.

Frequently he would detect a movement here or there among the trees; and
at such times he could easily imagine that some animal belonging to the
forest was creeping closer in. The question was, whether simple
curiosity urged them to do this thing, or a design upon the occupants of
the camp.

Frank had been in other situations calling for considerable pluck, and
never failed to meet the emergency, nor did he now.

It must have been some three hours back that Andy lay down to
sleep. That had been the limit of time arranged upon; but Fra
