"I shall be glad to have your company," said Dorothy.

"Thank you," he answered. "Now, if you will help me sew the silk together, we will begin to work on our balloon."

So Dorothy took a needle and thread, and as fast as Oz cut the strips of silk into proper shape the girl sewed them neatly together. First there was a strip of light green silk, then a strip of dark green and then a strip of emerald green; for Oz had a fancy to make the balloon in different shades of the color about them. It took three days to sew all the strips together, but when it was finished they had a big bag of green silk more than twenty feet long.

Then Oz painted it on the inside with a coat of thin glue, to make it airtight, after which he announced that the balloon was ready.

"But we must have a basket to ride in," he said. So he sent the soldier with the green whiskers for a big clothes basket, which he fastened with many ropes to the bottom of the balloon.

When it was all ready, Oz sent word to his people that he was going to make a visit to a great brother Wizard who lived in the clouds. The news spread rapidly throughout the city and everyone came to see the wonderful sight.

Oz ordered the balloon carried out in front of the Palace, and the people gazed upon it with much curiosity. The Tin Woodman had chopped a big pile of wood, and now he made a fire of it, and Oz held the bottom of the balloon over the fire so that the hot air that arose from it would be caught in the silken bag. Gradually the balloon swelled out and rose into the air, until finally the basket just touched the ground.

While the Woodman was making a ladder from wood which he found in the forest Dorothy lay down and slept, for she was tired by the long walk. The Lion also curled himself up to sleep and Toto lay beside him.

The Scarecrow watched the Woodman while he worked, and said to him:

"I cannot think why this wall is here, nor what it is made of."

"Rest your brains and do not worry about the wall," replied the Woodman. "When we have climbed over it, we shall know what is on the other side."

After a time the ladder was finished. It looked clumsy, but the Tin Woodman was sure it was strong and would answer their purpose. The Scarecrow waked Dorothy and the Lion and Toto, and told them that the ladder was ready. The Scarecrow climbed up the ladder first, but he was so awkward that Dorothy had to follow close behind and keep him from falling off. When he got his head over the top of the wall the Scarecrow said, "Oh, my!"

"Go on," exclaimed Dorothy.

So the Scarecrow climbed farther up and sat down on the top of the wall, and Dorothy put her head over and cried, "Oh, my!" just as the Scarecrow had done.

Then Toto came up, and immediately began to bark, but Dorothy made him be still.

"Are there any other lions in this forest?" he asked.

"No; there were some, but the monster has eaten them all. And, besides, they were none of them nearly so large and brave as you."

"If I put an end to your enemy, will you bow down to me and obey me as King of the Forest?" inquired the Lion.

"We will do that gladly," returned the tiger; and all the other beasts roared with a mighty roar: "We will!"

"Where is this great spider of yours now?" asked the Lion.

"Yonder, among the oak trees," said the tiger, pointing with his forefoot.

"Take good care of these friends of mine," said the Lion, "and I will go at once to fight the monster."

He bade his comrades good–bye and marched proudly away to do battle with the enemy.

"Certainly," answered the Queen; "but it is a great way off, for you have had it at your backs all this time." Then she noticed Dorothy's Golden Cap, and said, "Why don't you use the charm of the Cap, and call the Winged Monkeys to you? They will carry you to the City of Oz in less than an hour."

"I didn't know there was a charm," answered Dorothy, in surprise. "What is it?"

"It is written inside the Golden Cap," replied the Queen of the Mice. "But if you are going to call the Winged Monkeys we must run away, for they are full of mischief and think it great fun to plague us."

"Won't they hurt me?" asked the girl anxiously.

"Oh, no. They must obey the wearer of the Cap. Good–bye!" And she scampered out of sight, with all the mice hurrying after her.

Dorothy looked inside the Golden Cap and saw some words written upon the lining. These, she thought, must be the charm, so she read the directions carefully and put the Cap upon her head.

"Ep–pe, pep–pe, kak–ke!" she said, standing on her left foot.

"What did you say?" asked the Scarecrow, who did not know what she was doing.

"Hil–lo, hol–lo, hel–lo!" Dorothy went on, standing this time on her right foot.

Of course each one of them expected to see the Wizard in the shape he had taken before, and all were greatly surprised when they looked about and saw no one at all in the room. They kept close to the door and closer to one another, for the stillness of the empty room was more dreadful than any of the forms they had seen Oz take.

Presently they heard a solemn Voice, that seemed to come from somewhere near the top of the great dome, and it said:

"I am Oz, the Great and Terrible. Why do you seek me?"

They looked again in every part of the room, and then, seeing no one, Dorothy asked, "Where are you?"

"I am everywhere," answered the Voice, "but to the eyes of common mortals I am invisible. I will now seat myself upon my throne, that you may converse with me." Indeed, the Voice seemed just then to come straight from the throne itself; so they walked toward it and stood in a row while Dorothy said:

"We have come to claim our promise, O Oz."

"What promise?" asked Oz.

"You promised to send me back to Kansas when the Wicked Witch was destroyed," said the girl.

"And you promised to give me brains," said the Scarecrow.

Then Oz got into the basket and said to all the people in a loud voice:

"I am now going away to make a visit. While I am gone the Scarecrow will rule over you. I command you to obey him as you would me."

The balloon was by this time tugging hard at the rope that held it to the ground, for the air within it was hot, and this made it so much lighter in weight than the air without that it pulled hard to rise into the sky.

"Come, Dorothy!" cried the Wizard. "Hurry up, or the balloon will fly away."

"I can't find Toto anywhere," replied Dorothy, who did not wish to leave her little dog behind. Toto had run into the crowd to bark at a kitten, and Dorothy at last found him. She picked him up and ran towards the balloon.

She was within a few steps of it, and Oz was holding out his hands to help her into the basket, when, crack! went the ropes, and the balloon rose into the air without her.

"Come back!" she screamed. "I want to go, too!"

"I can't come back, my dear," called Oz from the basket. "Good–bye!"

"Good–bye!" shouted everyone, and all eyes were turned upward to where the Wizard was riding in the basket, rising every moment farther and farther into the sky.
