"That was one of my tricks," answered Oz. "Step this way, please, and I will tell you all about it."
He led the way to a small chamber in the rear of the Throne Room, and they all followed him. He pointed to one corner, in which lay the great Head, made out of many thicknesses of paper, and with a carefully painted face.
"This I hung from the ceiling by a wire," said Oz. "I stood behind the screen and pulled a thread, to make the eyes move and the mouth open."
"But how about the voice?" she inquired.
"Oh, I am a ventriloquist," said the little man. "I can throw the sound of my voice wherever I wish, so that you thought it was coming out of the Head. Here are the other things I used to deceive you." He showed the Scarecrow the dress and the mask he had worn when he seemed to be the lovely Lady. And the Tin Woodman saw that his terrible Beast was nothing but a lot of skins, sewn together, with slats to keep their sides out. As for the Ball of Fire, the false Wizard had hung that also from the ceiling. It was really a ball of cotton, but when oil was poured upon it the ball burned fiercely.
"Really," said the Scarecrow, "you ought to be ashamed of yourself for being such a humbug."
"I am--I certainly am," answered the little man sorrowfully; "but it was the only thing I could do. Sit down, please, there are plenty of chairs; and I will tell you my story."
So they sat down and listened while he told the following tale.
"I was born in Omaha--"
"Why, that isn't very far from Kansas!" cried Dorothy.
"No, but it's farther from here," he said, shaking his head at her sadly. "When I grew up I became a ventriloquist, and at that I was very well trained by a great master. I can imitate any kind of a bird or beast." Here he mewed so like a kitten that Toto pricked up his ears and looked everywhere to see where she was. "After a time," continued Oz, "I tired of that, and became a balloonist."
"What is that?" asked Dorothy.
"A man who goes up in a balloon on circus day, so as to draw a crowd of people together and get them to pay to see the circus," he explained.
"Oh," she said, "I know."
"Well, one day I went up in a balloon and the ropes got twisted, so that I couldn't come down again. It went way up above the clouds, so far that a current of air struck it and carried it many, many miles away. For a day and a night I traveled through the air, and on the morning of the second day I awoke and found the balloon floating over a strange and beautiful country.
"It came down gradually, and I was not hurt a bit. But I found myself in the midst of a strange people, who, seeing me come from the clouds, thought I was a great Wizard. Of course I let them think so, because they were afraid of me, and promised to do anything I wished them to.
"Just to amuse myself, and keep the good people busy, I ordered them to build this City, and my Palace; and they did it all willingly and well. Then I thought, as the country was so green and beautiful, I would call it the Emerald City; and to make the name fit better I put green spectacles on all the people, so that everything they saw was green."
"But isn't everything here green?" asked Dorothy.
"No more than in any other city," replied Oz; "but when you wear green spectacles, why of course everything you see looks green to you. The Emerald City was built a great many years ago, for I was a young man when the balloon brought me here, and I am a very old man now. But my people have worn green glasses on their eyes so long that most of them think it really is an Emerald City, and it certainly is a beautiful place, abounding in jewels and precious metals, and every good thing that is needed to make one happy. I have been good to the people, and they like me; but ever since this Palace was built, I have shut myself up and would not see any of them.
