"I wouldn't be surprised if he's planning some deviltry," Carl remarked as they left the shop. "He's got some exaggerated notion about the Thunder Bird already."

"I'll bet he's been listening," exclaimed Carl, a little disturbed. "There's no tellin' what a half-cracked, superstitious Indian may get into his head."
