That was a new thought. Perhaps the scheming men knew this, and that is why they wanted to attack the old fisherman.

“We simply must go to his cabin,” decided Cora, “and find out what has happened. I can’t wait any longer.”

Wraps were quickly donned, and down to the dock went the girls. The Chelton was in running order, and soon they were out on the moonlit waters of the bay.

“There’s a light in his cabin,” said Cora, as they came out from behind a point, and had a view of the little cove where nestled Denny’s cottage.

“I hope the boys are there,” remarked Bess, “and that they have the villains all tied up and ready for delivery.”

“Ugh!” exclaimed Belle. “If they have I wish they’d send them by parcel post instead of asking us to take charge of them.”

“They’ll be harmless,” guaranteed Cora. “Besides, the Dixie can’t hold more than the boys; our boat is larger.”

“We could let the boys run this one, after the men are tied in her,” suggested Lottie, “and we could come home in the Dixie.”

“Never!” exclaimed Cora. “You can’t rely on her. I’ll stick to the Chelton.”

But if the girls had only known that, at that moment, far out on Crystal Bay, was the ill-fated Dixie, drifting to sea, while the boys tooted hopelessly for aid on the compressed air whistles!
