Motor-boat engines were popping everywhere. The club house was dressed in bright-colored bunting from veranda rail to ridge pole. Ladies strolled about beneath their parasols with correctly dressed yachtsmen, asking all sorts of absurd questions about the various boats that lay ready to take part in the various events. It was the day of the Hampton Yacht Club's regatta.

Among the throng the Boy Scouts threaded their way, watching with interest the events as they were run off, one after the other. But their minds were centered on the race for the trophy which, although there were several other entries, had been practically conceded to Sam Redding's hydroplane.

"She's a wonder," said one of the onlookers, pointing from the porch to the float, where Jack Curtiss, Bill Bender and Sam were leaning over their speedy craft, stripping her of every bit of weight not absolutely necessary. On the opposite side of the float the crew of the Flying Fish, the Snark, the Bonita and the Albacore were equally busy over their craft.

"Douse the engine with oil," directed Rob, as Merritt gave the piece of machinery a final inspection; "and how about that extra set of batteries?"

"They're aboard," rejoined Tubby, who was perspiringly removing cushions and other surplus gear from the fleet boat.

"That's right; if it comes to an emergency, we may need them," said Rob. "Nothing like being prepared."

"Do you think we have any show?" asked Tubby, who was to be a sort of general utility man in the crew. Rob was to steer.

"I don't see why not," rejoined the other, wiping his oily hands on a bit of waste. "The race is a handicap one, and we get an allowance on account of our engine not being as powerful as the hydroplane's."

The course to be run was a sort of elongated, or isosceles triangle. The turning point was at the head of the inlet, a buoy with a big red ball on it being placed just inside the rough waters of the bar. It made a course of about five miles. The race for the Hampton Motor Boat Club's cup, for which the boys and the others were entered, was twice round.

The waters about the club house were so dotted with motor craft which darted about in every direction that Commodore Wingate of the club and the other regatta officials had a hard time keeping the course clear for the contestants. On the threat, however, that the races would be called off if a clear course was not kept, order was finally obtained.
