"Coo-ee-oh's misfortune will prove a terrible blow to her people." "What do you mean by that?" asked Dorothy in surprise. "Seems to me the Skeezers are in luck to lose their cruel Queen."

But you are a mortal girl, Dorothy, and if your Magic Belt protected you from death you would have to lie forever at the bottom of the lake." "No, I'd rather die quickly," asserted the little girl. "But there are doors in the basement that open—to
