ctive recognized them, I think, Dick. He called them by name,
and seemed to know all about them. I suppose men who would dare to try
to do a thing like that must be old stagers. No man who was committing
his first crime would try anything so fiendish as wrecking a train and
taking the chance of killing a lot of innocent people, do you think?"

"I should say not! And there wasn't any chance about it, either. If
the train had been wrecked, going at sixty miles an hour or so, as it
would have been, if it was late, and trying to make up lost time, there
couldn't have been any result but a terrible wreck."

"I wonder if there were only three of them?" said Jack, thoughtfully.
"I've been thinking since that there may have been others in the gang
that weren't caught. There must have been someone to set the blockade
for the train, and I don't believe those fellows we caught had time to
do everything. They had to put Hudson out of the way, you see, and
keep him from using the telegraph to give warning. I've got an idea
there was at least one other man in it, and maybe more than that, who
didn't show up in the station at all."

"Well, if that's so, you'd better look out for yourself, Jack, in case
they try to get even with you for spoiling their little game. They'd
be apt to try to take that out of you."

"Perhaps they won't know I had anything to do with it. And, anyhow,
I'm not sure there was anyone else mixed up in it. That's only a guess
anyhow."

"I'd be careful, just the same. Don't go around alone at night--though
you'll be safe enough in the city, I guess, unless some of those people
that were mixed up in that kidnapping case get after you."

"They haven't anything more against me, or any more reason to be sore
at me, than at anyone else that was concerned in the whole job, anyhow.
But I'll keep my eyes open. I'll be glad to turn in pretty soon. I'm
pretty tired."

"I should think you would be. I am myself, and I haven't done as much
as you."

Soon after that sentries were posted, and the Scouts, wrapped in their
blankets, were all asleep in their lean-tos. Jack's sleeping partner,
Tom Binns, was not there, so he slept alone, on the edge of the camp,
and some distance from the campfire.

Tired as he was, he did not get to sleep at once. Out on the lake
puffing motor boats, running back and forth from the big summer hotel
at the head of the lake to the cottages that were clustered near the
dam,
