"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.

"One of my greatest fears was the Witches, for while I had no magical powers at all I soon found out that the Witches were really able to do wonderful things. There were four of them in this country, and they ruled the people who live in the North and South and East and West. Fortunately, the Witches of the North and South were good, and I knew they would do me no harm; but the Witches of the East and West were terribly wicked, and had they not thought I was more powerful than they themselves, they would surely have destroyed me. As it was, I lived in deadly fear of them for many years; so you can imagine how pleased I was when I heard your house had fallen on the Wicked Witch of the East. When you came to me, I was willing to promise anything if you would only do away with the other Witch; but, now that you have melted her, I am ashamed to say that I cannot keep my promises."

"I think you are a very bad man," said Dorothy.

He opened the big box, and Dorothy saw that it was filled with spectacles of every size and shape. All of them had green glasses in them. The Guardian of the Gates found a pair that would just fit Dorothy and put them over her eyes. There were two golden bands fastened to them that passed around the back of her head, where they were locked together by a little key that was at the end of a chain the Guardian of the Gates wore around his neck. When they were on, Dorothy could not take them off had she wished, but of course she did not wish to be blinded by the glare of the Emerald City, so she said nothing.

Then the green man fitted spectacles for the Scarecrow and the Tin Woodman and the Lion, and even on little Toto; and all were locked fast with the key.

Then the Guardian of the Gates put on his own glasses and told them he was ready to show them to the Palace. Taking a big golden key from a peg on the wall, he opened another gate, and they all followed him through the portal into the streets of the Emerald City.

Now the Scarecrow, who had expected to see the great Head Dorothy had told him of, was much astonished; but he answered her bravely.

"I am only a Scarecrow, stuffed with straw. Therefore I have no brains, and I come to you praying that you will put brains in my head instead of straw, so that I may become as much a man as any other in your dominions."

"Why should I do this for you?" asked the Lady.

"Because you are wise and powerful, and no one else can help me," answered the Scarecrow.

"I never grant favors without some return," said Oz; "but this much I will promise. If you will kill for me the Wicked Witch of the West, I will bestow upon you a great many brains, and such good brains that you will be the wisest man in all the Land of Oz."

"I thought you asked Dorothy to kill the Witch," said the Scarecrow, in surprise.

"So I did. I don't care who kills her. But until she is dead I will not grant your wish. Now go, and do not seek me again until you have earned the brains you so greatly desire."

The Scarecrow went sorrowfully back to his friends and told them what Oz had said; and Dorothy was surprised to find that the Great Wizard was not a Head, as she had seen him, but a lovely Lady.

Then all the Winged Monkeys, with much laughing and chattering and noise, flew into the air and were soon out of sight.

The Wicked Witch was both surprised and worried when she saw the mark on Dorothy's forehead, for she knew well that neither the Winged Monkeys nor she, herself, dare hurt the girl in any way. She looked down at Dorothy's feet, and seeing the Silver Shoes, began to tremble with fear, for she knew what a powerful charm belonged to them. At first the Witch was tempted to run away from Dorothy; but she happened to look into the child's eyes and saw how simple the soul behind them was, and that the little girl did not know of the wonderful power the Silver Shoes gave her. So the Wicked Witch laughed to herself, and thought, "I can still make her my slave, for she does not know how to use her power." Then she said to Dorothy, harshly and severely:

"Come with me; and see that you mind everything I tell you, for if you do not I will make an end of you, as I did of the Tin Woodman and the Scarecrow."

Dorothy followed her through many of the beautiful rooms in her castle until they came to the kitchen, where the Witch bade her clean the pots and kettles and sweep the floor and keep the fire fed with wood.

Dorothy went to work meekly, with her mind made up to work as hard as she could; for she was glad the Wicked Witch had decided not to kill her.
