“That’s my way of breaking a hoodoo,” said Bob.

“There would have been some in the box in the shack if you hadn’t insisted on eating the last box of sardines,” declared Ned, for often the boys would spend a day or two camping out on the island, and they had a small supply of provisions there.

“Well, I was hungry,” said the fat youth. “I had to eat ’em.”

“And you’re hungry now,” said Jerry.

“If we’ve got to stay here let’s go up to the cabin, and see what we can do about sleeping,” proposed Ned. “It’s pretty evident that we can’t get the motor going now. There must be something wrong with the valves. It’ll have to be taken apart. Let’s go to the shack.”
