"They can, yes, and there isn't anybody I'd trust quicker than I would McGlory; but, if anything should happen to the Sprite between now and Tuesday, I want to be the one who's to blame."

"I guess I know how you stack up," observed Lorry, with a touch of genuine feeling. "You're doing a whole lot for me, Matt, and my folks know it and appreciate it just as much as I do. I hope I can pay you back some time."

"Nonsense, George!" deprecated Matt. "Do you think there isn't any fun in this thing for me? I've enjoyed myself every minute I've been tinkering with the Sprite, and the best part of it all will come when I show the Dart the way across the finish line next Tuesday."

Half an hour later Lorry got into his hired launch and started for home. All was quiet and peaceable in the boathouse, but, even then, a storm of trouble was preparing to break—a storm that was to try the three friends to the uttermost and to come within a hair's breadth of ruining their prospects in the power-boat contest.


[CHAPTER VIII.]

THE PLOTTERS.

Merton and his seven companions were a disgruntled lot when they returned to Madison after forcing an interview with Motor Matt, having their propositions rejected and then watching him get away after unmasking the "commodore."

Merton drove the touring car straight for home, turned it over to the gardener—who was also something of a chauffeur—and then ushered his friends into his father's study, in the house.

The butler and the chef had been left to look after Merton's comfort. Merton immediately sent the butler to the ice box for several bottles of beer, and the lads proceeded to drown their disgust and disappointment in drink.
