ment. The lad found it was working very well, but he decided with a new kind of spark plugs for the two cylinders that he could get more speed out of it. Finally the forward compartment was painted, a general overhauling given the hull and Tom was ready to put his boat to a good test.
"Come on, Ned," he said to his chum early one evening after Mr. Swift had said he was too tired to go out on a trial run. "We'll see what the Arrow will do now."
From the time Tom started up the motor it was evident that the boat was going through the water at a rapid rate. For a mile or more the two lads speeded along, enjoying it hugely. Then Ned exclaimed:
"Something's coming behind us."
Tom turned his head and looked. Then he called out:
"It's Mr. Hastings in his new Carlopa. I wonder if he wants a race?"
"Guess he'd have it all his own way," suggested Ned.
"Oh, I don't know. I can get a little more speed out of my boat."
Tom waited until the former owner of the Arrow was up to him.
"Want a race?" asked Mr. Hastings good-naturedly.
