“He’ll have a fine time living over on Island Number One at this season,” whispered Billy to Dan.

“Don’t let mother hear you,” replied the older boy, quickly. “She’d only worry.”

“Better let ‘Dummy’ do the worrying,” chuckled Billy.

“Well! it’s mighty odd,” said Dan, shaking his head. “And I really would like to know what’s buried on the island.”

“So would I,” said Billy. “Treasure—eh?”

“You’ve got treasure on the brain, boy,” grinned the older youth. “You’re getting mercenary. Haven’t you got wealth enough? We’re capitalists.”

“Yes—I know,” said Billy, nodding. “But I wonder if we’ve got money enough to get us the fastest iceboat that’s going to be raced on the Colasha this winter?”

“Ah! now you’ve said it,” agreed Dan. “But it isn’t going to be money that will get us that boat. We’ve got to learn something about iceboat building as well as iceboat sailing.”

“Huh! that blamed little wisp, Barry Spink,” grunted Billy.

“What about him now?” asked Dan, laughing.
