Kaliko cautiously stuck his head through the doorway and found the goat chewing the embroidery of his royal cloak, which he had left lying over the throne, while Rinkitink was reading his manuscript on "How to be Good" and chuckling over its advice. The Nome King seemed greatly disappointed as he came in and resumed his seat on the throne. Said Rinkitink with a chuckle: "We've really had a peaceful time, Kaliko, although not the pieceful time you expected. Forgive me if I indulge in a laugh--hoo, hoo, hoo-hee, heek-keek-eek! And now, tell me; aren't you getting tired of trying to injure us?" "Eh--heh," said the Nome King. "I see now that your magic can protect you from all my arts. But is the boy Inga as, well protected as Your Majesty and the goat?' "Why do you ask?" inquired Rinkitink, uneasy at the question because he remembered he had not seen the little Prince of Pingaree that morning. "Because," said Kaliko, "the boy has been undergoing trials far greater and more dangerous than any you have encountered, and it has been hundreds of years since anyone has been able to escape alive from the perils of my Three Trick Caverns." King Rinkitink was much alarmed at hearing this, for although he knew that Inga possessed the Blue Pearl, that would only give to him marvelous strength, and perhaps strength alone would not enable him to escape from danger. But he would not let Kaliko see the fear he felt for Inga's safety, so he said in a careless way: "You're a mighty poor magician, Kaliko, and I'll give you my crown if Inga hasn't escaped any danger you have threatened him with." "Your whole crown is not worth one of the valuable diamonds in my crown," answered the Nome King, "but I'll take it. Let us go at once, therefore, and see what has become of the boy Prince, for if he is not destroyed by this time I will admit he cannot be injured by any of the magic arts which I have at my command." He left the room, accompanied by Klik, who had now rejoined his master, and by Rinkitink riding upon Bilbil. After traversing several of the huge caverns they entered one that was somewhat more bright and cheerful than the others, where the Nome King paused before a wall of rock. Then Klik pressed a secret spring and a section of the wall opened and disclosed the corridor where Prince Inga stood facing them. "Tarts and tadpoles!" cried Kaliko in surprise. "The boy is still alive!" Chapter Twenty Dorothy to the Rescue
