“Why, fix it so that it won’t be possible for old Grigg to make trouble for us in the States.”

“How?”

“Simple enough. We can easily overpower those kids, and as for the professor and Tubbs, we’ll lock ’em in the cabin.”

“Say, cap, you are a schemer!” observed the mate, in rather sarcastic admiration, “and then I suppose we’ll sail for home and be arrested and imprisoned as pirates?”

“Not at all,” was the reply. “We don’t need to go home. South America’s good enough for me. It’s Chile that the old cove is headed for, ain’t it?”

“So his papers said.”

“All right, then. We’ll make the whole bunch prisoners, land ’em on an island some place, and then we’ll sail on to Chile ourselves, and have a try at finding this old lost city. By the way, did you make a tracing of that map you found in the professor’s desk?”

“Did I? Well, I should say so. I’ve got it in my pocketbook now. That’s likely to mean dollars and cents to us later on.”

“That’s so. Now then, you go and tell the crew what we are going to do. They won’t cut up rough about it, especially if they think there is money in it.”

“All right. I’m off. But see here, how are you going to do it? Those kids look pretty husky.”
