"I wonder if I'll meet Andy Foger and his cronies again?" he thought. "Not very likely to, I guess, if they're off on a tour. Well, I'm just as well satisfied.

Mr. Barton Swift was a natural Inventor. From a boy he had been interested in things mechanical, and one of his first efforts had been to arrange a system of pulleys, belts and gears so that the windmill would operate the churn in the old farmhouse where he was born.
