Now they are all set free, and are grateful to you for the favor."
"Who are the Munchkins?" inquired Dorothy.
"They are the people who live in this land of the East where the Wicked Witch ruled."
"Are you a Munchkin?" asked Dorothy.
"No, but I am their friend, although I live in the land of the North.
When they saw the Witch of the East was dead the Munchkins sent a swift messenger to me, and I came at once.
I am the Witch of the North."
"Oh, gracious!" cried Dorothy. "Are you a real witch?"
"Yes, indeed," answered the little woman.
"But I am a good witch, and the people love me.
I am not as powerful as the Wicked Witch was who ruled here, or I should have set the people free myself."
"But I thought all Witches were wicked," said the girl, who was half frightened at facing a real witch."
"Oh, no, that is a great mistake.
There were only four witches in all the Land of Oz, and two of them, those who live in the North and the South, are good witches.
I know this is true, for I am one of them myself, and cannot be mistaken.
Those who dwelt in the East and the West were, indeed, wicked witches; but now that you have killed one of them, there is but one Wicked Witch in all the Land of Oz--the one who lives in the West."
"But," said Dorothy, after a moments thought, "Aunt Em has told me that the witches were all dead--years and years ago."
"Who is Aunt Em?" inquired the little old woman.
"She is my aunt who lives in Kansas, where I came from."
The Witch of the North seemed to think for a time, with her head bowed and her eyes upon the ground.
