"We!" exclaimed the girl. "Are you going with me?"

"Yes, of course," replied Oz. "I am tired of being such a humbug. If I should go out of this Palace my people would soon discover I am not a Wizard, and then they would be vexed with me for having deceived them. So I have to stay shut up in these rooms all day, and it gets tiresome. I'd much rather go back to Kansas with you and be in a circus again."

"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.
