"Well, I guess this isn't your property!" blustered the man. "I have as good a right here as you have, and you can't have me arrested for that."
"Perhaps not," admitted Tom. "You may have a right on this land, but if you are honest, and had no bad intentions, why were you sneaking up, trying to keep out of sight? And why did you have a big knife?"
"That's my business, young man."
"All right, then I'll make it my business, too," went on the young inventor. "Hold him, Koku, until I can find Mr. Damon, or Ned, and I'll see what's best to be done. I wish Mr. Whitford was here."
"Aren't you going to let me go?" demanded the man.
"I certainly am not!" declared Tom firmly. "I'm going to find out more about you. I haven't any objections to any one coming to look at my airship, out of curiosity, but when they come up like a snake in the grass and with a big knife, then I get suspicious, and I want to know more about them."
"Well, you won't know anything more about me!" snarled the fellow. "And it will be the worse for you, if you don't let me go. You'd better!" he threatened.
