"It's somewhere around there; or in the caves. You folks can laugh," said Billy, "but those foreigners talked enough English for me to understand that the money——"
"In a lard kettle," put in Bobby, chuckling.
"In a lard can," corrected Billy, "was hidden on the island, and was not far from the caves."
"Maybe when the man you said was hanging around so long disappeared, he took the treasure with him," laughed Dorothy Lockwood.
"And I bet I know who the two men were whom Billy heard quarreling over a lard can," cried Dora.
"You know, do you?" demanded Billy. "Well, who were they?"
"Tony Allegretto and the man the police found him fighting with," said Dora promptly.
"Great Scott!" gasped Chetwood Belding. "Do you hear that, Lance?"
"Never thought of 'em!" answered his chum.
"Buried treasure, too!" said Chet, thoughtfully. "Tony said they were quarreling over money."
