Early the following morning a gay cavalcade set out to visit the famous Sorceress, Glinda the Good. Ozma and Dorothy rode in a chariot drawn by the Cowardly Lion and the Hungry Tiger, while the Sawhorse drew the red wagon in which rode the rest of the party.
With hearts light and free from care they traveled merrily along through the lovely and fascinating Land of Oz, and in good season reached the stately castle in which resided the Sorceress.
Glinda knew that they were coming.
"I have been reading about you in my Magic Book," she said, as she greeted them in her gracious way.
"What is your Magic Book like?" inquired Aunt Em, curiously.
"It is a record of everything that happens," replied the Sorceress.
"As soon as an event takes place, anywhere in the world, it is immediately found printed in my Magic Book. So when I read its pages I am well informed."
"Did it tell you how our enemies drank the Water of 'Blivion?" asked Dorothy.
"Yes, my dear; it told all about it. And also it told me you were all coming to my castle, and why."
"Then," said Ozma, "I suppose you know what is in my mind, and that I am seeking a way to prevent any one in the future from discovering the Land of Oz."
"Yes; I know that. And while you were on your journey I have thought of a way to accomplish your desire. For it seems to me unwise to allow too many outside people to come here. Dorothy, with her uncle and aunt, has now returned to Oz to live always, and there is no reason why we should leave any way open for others to travel uninvited to our fairyland. Let us make it impossible for any one ever to communicate with us in any way, after this. Then we may live peacefully and contentedly."
"Your advice is wise," returned Ozma. "I thank you, Glinda, for your promise to assist me."
"But how can you do it?" asked Dorothy. "How can you keep every one from ever finding Oz?"
"By ****** our country invisible to all eyes but our own," replied the Sorceress, smiling. "I have a magic charm powerful enough to accomplish that wonderful feat, and now that we have been warned of our danger by the Nome King's invasion, I believe we must not hesitate to separate ourselves forever from all the rest of the world."
"I agree with you," said the Ruler of Oz.
"Won't it make any difference to us?" asked Dorothy, doubtfully.
"No, my dear," Glinda answered, assuringly. "We shall still be able to see each other and everything in the Land of Oz. It won't affect us at all; but those who fly through the air over our country will look down and see nothing at all. Those who come to the edge of the desert, or try to cross it, will catch no glimpse of Oz, or know in what direction it lies. No one will try to tunnel to us again because we cannot be seen and therefore cannot be found. In other words, the Land of Oz will entirely disappear from the knowledge of the rest of the world."
"That's all right," said Dorothy, cheerfully. "You may make Oz invis'ble as soon as you please, for all I care."
"It is already invisible," Glinda stated. "I knew Ozma's wishes, and performed the Magic Spell before you arrived."
Ozma seized the hand of the Sorceress and pressed it gratefully.
"Thank you!" she said.
