As the boys approached the wharf beside which their boat floated, a man came toward them and spoke to them. He was the man with the crooked eye and broken nose.

"I hear you chaps are thinkin' of goin' down to Devil Island?" he said, one eye seeming to look at Frank while the other looked at Bruce. "Is that right?"

"We may go down there," answered Frank.

"To-morrow."

"Better not."

"Why?"

"It's dangerous."

"How?"

"You heard the yarns about the critter on the island, and you ought to know why."
