"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.

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.

And that was the last any of them ever saw of Oz, the Wonderful Wizard, though he may have reached Omaha safely, and be there now, for all we know. But the people remembered him lovingly, and said to one another:

"Oz was always our friend. When he was here he built for us this beautiful Emerald City, and now he is gone he has left the Wise Scarecrow to rule over us."

Still, for many days they grieved over the loss of the Wonderful Wizard, and would not be comforted.

Dorothy wept bitterly at the passing of her hope to get home to Kansas again; but when she thought it all over she was glad she had not gone up in a balloon. And she also felt sorry at losing Oz, and so did her companions.

The Tin Woodman came to her and said:

"Truly I should be ungrateful if I failed to mourn for the man who gave me my lovely heart. I should like to cry a little because Oz is gone, if you will kindly wipe away my tears, so that I shall not rust."

"With pleasure," she answered, and brought a towel at once. Then the Tin Woodman wept for several minutes, and she watched the tears carefully and wiped them away with the towel. When he had finished, he thanked her kindly and oiled himself thoroughly with his jeweled oil-can, to guard against mishap.

The Scarecrow was now the ruler of the Emerald City, and although he was not a Wizard the people were proud of him. "For," they said, "there is not another city in all the world that is ruled by a stuffed man." And, so far as they knew, they were quite right.

The morning after the balloon had gone up with Oz, the four travelers met in the Throne Room and talked matters over. The Scarecrow sat in the big throne and the others stood respectfully before him.

"We are not so unlucky," said the new ruler, "for this Palace and the Emerald City belong to us, and we can do just as we please. When I remember that a short time ago I was up on a pole in a farmer's cornfield, and that now I am the ruler of this beautiful City, I am quite satisfied with my lot."

"I also," said the Tin Woodman, "am well-pleased with my new heart; and, really, that was the only thing I wished in all the world."

"For my part, I am content in knowing I am as brave as any beast that ever lived, if not braver," said the Lion modestly.

"If Dorothy would only be contented to live in the Emerald City," continued the Scarecrow, "we might all be happy together."

"But I don't want to live here," cried Dorothy. "I want to go to Kansas, and live with Aunt Em and Uncle Henry."

"Well, then, what can be done?" inquired the Woodman.

The Scarecrow decided to think, and he thought so hard that the pins and needles began to stick out of his brains. Finally he said:

"Why not call the Winged Monkeys, and ask them to carry you over the desert?"

"I never thought of that!" said Dorothy joyfully. "It's just the thing. I'll go at once for the Golden Cap."

When she brought it into the Throne Room she spoke the magic words, and soon the band of Winged Monkeys flew in through the open window and stood beside her.

"This is the second time you have called us," said the Monkey King, bowing before the little girl. "What do you wish?"

"I want you to fly with me to Kansas," said Dorothy.

But the Monkey King shook his head.

"That cannot be done," he said. "We belong to this country alone, and cannot leave it. There has never been a Winged Monkey in Kansas yet, and I suppose there never will be, for they don't belong there. We shall be glad to serve you in any way in our power, but we cannot cross the desert. Good-bye."

And with another bow, the Monkey King spread his wings and flew away through the window, followed by all his band.

Dorothy was ready to cry with disappointment. "I have wasted the charm of the Golden Cap to no purpose," she said, "for the Winged Monkeys cannot help me."

"It is certainly too bad!" said the tender-hearted Woodman.

The Scarecrow was thinking again, and his head bulged out so horribly that Dorothy feared it would burst.

"Let us call in the soldier with the green whiskers," he said, "and ask his advice."

So the soldier was summoned and entered the Throne Room timidly, for while Oz was alive he never was allowed to come farther than the door.

"This little girl," said the Scarecrow to the soldier, "wishes to cross the desert. How can she do so?"

"I cannot tell," answered the soldier, "for nobody has ever crossed the desert, unless it is Oz himself."

"Is there no one who can help me?" asked Dorothy earnestly.
