hadn't given the signal just then," chuckled Will, holding up his
machine.

"A puncture, Frank?" demanded Jerry, who had been in the rear.

"Not at all. I thought I heard some one shouting. Perhaps I was
mistaken, for with a lot of motors popping away it's hard to be sure.
Still, we can stop for a minute and listen," remarked Frank seriously.

"Shouting--for help?" repeated Will, looking around nervously.

"That's queer," cried Bluff, "that we seldom go out anywhere but what
somebody calls on us for assistance. Think of it! There was the town
bully, Andy Lasher, who was caught under that falling tree in the storm,
and rescued by Jerry."

"That's a fact; and then there was Jed, the bound boy, you remember,
fellows," went on Will eagerly.

"Not to mention the saving of the aeronaut from the burning hotel by
Frank, here; and last, but not least, our giving that little Joe the
glad hand down South," observed Jerry, joining in with enthusiasm.

"Yes, but there are a few rescues you seem to forget, Jerry. How about
that time when the wild dogs had you chasing around the tree?" asked
Bluff, grinning.

"Oh, that isn't in the same class. You forget that I got out of that
scrape by my own exertions," replied the other.
