For three days Dorothy heard nothing from Oz. These were sad days for the little girl, although her friends were all quite happy and contented. The Scarecrow told them there were wonderful thoughts in his head; but he would not say what they were because he knew no one could understand them but himself. When the Tin Woodman walked about he felt his heart rattling around in his breast; and he told Dorothy he had discovered it to be a kinder and more tender heart than the one he had owned when he was made of flesh. The Lion declared he was afraid of nothing on earth, and would gladly face an army or a dozen of the fierce Kalidahs.

　Thus each of the little party was satisfied except Dorothy, who longed more than ever to get back to Kansas. On the fourth day, to her great joy, Oz sent for her, and when she entered the Throne Room he greeted her pleasantly:

　"Sit down, my dear; I think I have found the way to get you out of this country."

　"And back to Kansas?" she asked eagerly.

　"Well, I'm not sure about Kansas," said Oz, "for I haven't the faintest notion which way it lies. But the first thing to do is to cross the desert, and then it should be easy to find your way home."

　"How can I cross the desert?" she inquired.

　"Well, I'll tell you what I think," said the little man. "You see, when I came to this country it was in a balloon. You also came through the air, being carried by a cyclone. So I believe the best way to get across the desert will be through the air. Now, it is quite beyond my powers to make a cyclone; but I've been thinking the matter over, and I believe I can make a balloon."

　"How?" asked Dorothy.

　"A balloon," said Oz, "is made of silk, which is coated with glue to keep the gas in it. I have plenty of silk in the Palace, so it will be no trouble to make the balloon. But in all this country there is no gas to fill the balloon with, to make it float."

　"If it won't float," remarked Dorothy, "it will be of no use to us."

　"True," answered Oz. "But there is another way to make it float, which is to fill it with hot air. Hot air isn't as good as gas, for if the air should get cold the balloon would come down in the desert, and we should be lost."

　"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 ............
