"I wonder if it is strong?"said Dorothy musingly as she eyed the queer castle.

"I suppose it is, since a magician built it," answered the Wizard. "With magic to protect it, even a paper castle might be as strong as if made of stone. This Ugu must be a man of ideas, because he does things in a different way from other people."

"Yes. No one else would steal our dear Ozma," sighed tiny Trot.

"I wonder if Ozma is there?" said Betsy, indicating the castle with a nod of her head.

"Where else could she be?" asked Scraps.

"Suppose we ask the Pink Bear," suggested Dorothy.

That seemed a good idea, so they halted the procession, and the Bear King held the little Pink Bear on his lap and turned the crank in its side and asked, "Where is Ozma of Oz?"

And the little Pink Bear answered, "She is in a hole in the ground a half mile away at your left."

"Good gracious!" cried Dorothy.

"Then she is not in Ugu's castle at all."

"It is lucky we asked that question," said the Wizard, "for if we can find Ozma and rescue her, there will be no need for us to fight that wicked and dangerous magician."
