After Kaliko had failed in his attempts to destroy his guests, as has been related, the Nome King did nothing more to injure them but treated them in a friendly manner. He refused, however, to permit Inga to see or to speak with his father and mother, or even to know in what part of the underground caverns they were confined.

"You are able to protect your lives and persons, I freely admit," said Kaliko; "but I firmly believe you have no power, either of magic or otherwise, to take from me the captives I have agreed to keep for King Gos."

Inga would not agree to this. He determined not to leave the caverns until he had liberated his father and mother, although he did not then know how that could be accomplished. As for Rinkitink, the jolly King was well fed and had a good bed to sleep upon, so he was not worrying about anything and seemed in no hurry to go away.

Kaliko and Rinkitink were engaged in pitching a game with solid gold quoits, on the floor of the royal chamber, and Inga and Bilbil were watching them, when Klik came running in, his hair standing on end with excitement, and cried out that the Wizard of Oz and Dorothy were approaching.

Kaliko turned pale on hearing this unwelcome news and, abandoning his game, went to sit in his ivory throne and try to think what had brought these fearful visitors to his domain.

"Who is Dorothy?" asked Inga.

"She is a little girl who once lived in Kansas," replied Klik, with a shudder, "but she now lives in Ozma's palace at the Emerald City and is a Princess of Oz -- which means that she is a terrible foe to deal with."

"Doesn't she like the nomes?" inquired the boy.

"It isn't that," said King Kaliko, with a groan, "but she insists on the nomes being goody-goody, which is contrary to their natures. Dorothy gets angry if I do the least thing that is wicked, and tries to make me stop it, and that naturally makes me downhearted. I can't imagine why she has come here just now, for I've been behaving very well lately. As for that Wizard of Oz, he's chock-full of magic that I can't overcome, for he learned it from Glinda, who is the most powerful sorceress in the world. Woe is me! Why didn't Dorothy and the Wizard stay in Oz, where they belong?"

Inga and Rinkitink listened to this with much joy, for at once the idea came to them both to plead with Dorothy to help them. Even Bilbil pricked up his ears when he heard the Wizard of Oz mentioned, and the goat seemed much less surly, and more thoughtful than usual.

A few minutes later a nome came to say that Dorothy and the Wizard had arrived and demanded admittance, so Klik was sent to usher them into the royal presence of the Nome King.

As soon as she came in the little girl ran up to the boy Prince and seized both his hands.

"Oh, Inga!" she exclaimed, "I'm so glad to find you alive and well."

Inga was astonished at so warm a greeting. Making a low bow he said:

"I don't think we have met before, Princess."

"No, indeed," replied Dorothy, "but I know all about you and I've come to help you and King Rinkitink out of your troubles." Then she turned to the Nome King and continued: "You ought to be ashamed of yourself, King Kaliko, to treat an honest Prince and an honest King so badly."

"I haven't done anything to them," whined Kaliko, trembling as her eyes flashed upon him.

"No; but you tried to, an' that's just as bad, if not worse," said Dorothy, who was very indignant. "And now I want you to send for the King and Queen of Pingaree and have them brought here immejitly!"

"I won't," said Kaliko.

"Yes, you will!" cried Dorothy, stamping her foot at him. "I won't have those poor people made unhappy any longer, or separated from their little boy. Why, it's dreadful, Kaliko, an' I'm su'prised at you. You must be more wicked than I thought you were."

"I can't do it, Dorothy," said the Nome King, almost weeping with despair. "I promised King Gos I'd keep them captives. You wouldn't ask me to break my promise, would you?"
