"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.
"All the same," said the Scarecrow, "she needs a heart as much as the Tin Woodman."
On the next morning the soldier with the green whiskers came to the Tin Woodman and said:
"Oz has sent for you. Follow me."
