ng, that
there was enough dynamite underneath it to blow half the town up if it
was set properly."

Scarcely had the two men closed the door when the Scouts made a
simultaneous leap for it. But, as they moved, they felt the bump of
the freight engine against the car and a moment later it began to move.
It was too late for them to get off, and they could only sit and watch
that pile of sacking, with its deadly secret beneath it, wondering if
every moment was not to be their last. Every time the car jolted over
a frog in the rail they jumped, wondering why the deadly stuff did not
explode, and Jack was not ashamed to admit afterward that he was sick
with fear during the whole terrible ride. But it ended at last, with
the dynamite still safe and undisturbed, and they breathed great sighs
of relief as they realized that the first and probably the worst of
their perils was really over.

Mr. Simms was incredulous when they reached him and told him of what
they had discovered, but the dynamite was a witness not to be
discredited, and he had to believe when he saw that. With the utmost
care it was removed and placed in water, and then they began to make

CHAPTER XV

THE DYNAMITERS

"Well," said Mr. Simms, "that is a providential discovery, certainly!
If they had been allowed to reach that car of dynamite and set off all
that stuff there would have been precious little left of us or the

them from doing anything else?"

"I think we'd better leave the car just as it is, and even fix
something under that sacking to look like the dynamite," said Jack.
"If they get to it at all they will be in a terrible hurry, certainly,
and they won't stop to look to see if it's the right stuff. Then, if
we are watching them we can catch them red-handed, and it will be just
the ones that are making all the trouble that will be caught. Big Ed
Willis and his gang are perfectly willing to sneak up in the night and
set some dynamite to blow up innocent people, but they'll leave others
to bear the brunt of their crimes, every time."

"That's a good idea," said Carew. "I think we'd better fix that up
right away, Mr. Simms. Now, how about you, boys? Do you think you can
keep a sharp enough lookout to be able to spot those fellows when they
come in?"

"Yes, sir, I do! They'll be careful to dodge the places that would
ordinarily be watched. I thi
