"and, as I told your young friend, I've been trying for some time to bag the men at the summer camp. They number quite a few, and if they don't do anything worse, they run a gambling game there. I'm pretty sure, if the bank robbers are in this vicinity, they're in that camp. Of course all the men there may not have been engaged in looting the vault, and they may not all know of it, but it won't do any harm to round-up the whole bunch."
After a tour of the craft, and waiting to take a little refreshment with his new friends, the sheriff left, promising to come as early on the morrow as possible.
"Let's go to bed," suggested Mr. Sharp, after a bit. "We've got hard work ahead of us to-morrow."
They were up early, and, in the seclusion of the little glade in the woods, Tom and Mr. Sharp went over every part of the airship.
The sheriff arrived about nine o'clock, and announced that he had started off through the woods, to surround the camp, twenty-five men.
"They'll be there at noon," Mr. Durkin said, "and will close in when I give the signal, which will be two shots fired. I heard just before I came here that there are some new arrivals at the camp."
