monoplane was stored.

As he did so Frank uttered an exclamation of surprise.

"Why, there's a light over by the hangar!" he burst out. "Now, what
under the sun do you suppose that old fool of a Shea can be doing? Oh,
my! Look at the flame jump up! Why, as sure as you live I believe the
shed's afire! And I can see the figure of a man moving about. This is no
accident, but something worse! And it looks as if the little 'Bug' might
be going up in smoke in a jiffy unless I can sprawl over the fence here
and get on the spot mighty quick!"




CHAPTER V.


A WARM FIVE MINUTES.

"Fire! Fire!"

So Frank shouted, even as he jumped over the fence, and made a bee line
for the center of the big field, where the shed lay in which the
precious monoplane was stored.

He had hastily leaned his bicycle against the fence as he made the
plunge. Nor did he cease to let out constant yells while running across
the open as fast as his agile legs could carry him. Twice he tripped
over some object and nearly fell, only to recover himself and speed on.
