"I think that's a good idea," commented Mr. Swift.

It was four days after his purchase of the boat before Tom was ready to make a long trip in it. Up to that time he had gone on short spins not far from the dock, in order to test the engine adjustment. 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 and 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.
