On the hull at the bow was painted the name in bold black letters: Jolly Roger; and above, from a pole at the forward end of the roof-deck was a white flag which, when the little breeze spread its folds, displayed the gruesome skull-and-cross-bones in black!

“Must be a pirate ship,” said Roy, and Harry looked somewhat uneasy until she saw that the others took it as a joke.

FOR SALE!
INQUIRE WITHIN
OR WITHOUT

“What’s it mean by ‘without’?” asked Harry.

“Without any money,” Chub suggested.
