"We hope he'll be in Seawall next month. He is in Europe now," returned Frank; "and we will keep our purchase a secret from him at present. When he gets back we will suddenly burst on his vision in all our glory."

"Good old David," said Jimmy; "won't he be glad? We can take him along as member of the crew. He'd make a ripping coxswain."

"I don't know what a coxswain has to do, but he'd be all right for any job," said Lewis.

"And with all this crew you propose," said Mr. Armstrong, "where are you going to put your passengers?"

"Oh, don't worry about that, Dad; she's a big boat. Wait till you see her. Are you willing to advance us running expenses for gasoline and oil till we get our first money on fares?"

"Provided it isn't more than a hundred dollars a day," returned his father, laughing.

The next morning was spent down at the Simpkins wharf with the mechanic. There was little to do. The motor was one of the best types, but while it had been idle it had acquired some rust. The pistons stuck hard in the cylinders for a time, but they were soon freed and the engine turned over as smoothly as the day it left the shop. When the batteries were renewed, the carburetor adjusted and the gas and oil tanks filled, the mechanic gave the fly wheel a sharp turn. Instantly there was an explosion; another and another followed, and as the motor picked up speed under the careful manipulation of the mechanic, the explosions from the exhaust settled down into a steady purr.

"That's a peach of an engine," said Frank to the mechanic. "How much speed do you think the boat has?"

"Dunno," replied the mechanic; "mebby twenty miles, mebby more. Don't think there's many around here that'll get away from her very much. Now we're ready to see how she goes."
