"That's a good plan," commented Mr. Sharp, "but are you sure these are the men we want? It's pretty vague, I think, but of course the clue Tom got is pretty slim; merely the name Shagmon."
"Well, this is Shagmon," went on the sheriff, "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."
"Maybe those are the men I overheard talking in the office building," suggested Tom. "They probably came to get their share. Well, we must swoop down on them before they have time to distribute the money."
"That's what!" agreed the county official. Mr. Durkin was even more impressed by the airship in the daytime than he had been at night. He examined every part, and when the time came to start, he was almost as unconcerned as any of the three travelers who had covered many hundreds of miles in the air.
"This is certainly great!" cried the sheriff, as the airship rose swiftly under the influence of the powerful gas.
