The two chums kept on down the river toward the main part of the town, for Tom’s home was on the outskirts. “I want to get a new set of batteries,” explained the owner of the Tag. “I always carry two sets so I can run on one even if some of them give out, and one set I’ve got now is running pretty low. This motor won’t start on the magneto, for some reason, so I have to start on the batteries and then switch over.” They soon reached the town, and Tom tied his craft at a public dock.
