“Oh, I’ve had him a good while. He’s one of a team, but I sold my boat and—”

“This mule never towed a boat!” said the boy quickly.

As for the strange tramp—for that is what he was—he seemed very angry.

“What do you mean?” he cried. “This mule isn’t any trick mule!”

“Oh, isn’t he?” asked Neale quietly. “And I suppose he never was in a circus, either?”

“Of course not!” declared the man. “Who are you, anyhow, and what do you mean by talking that way?”
