“Kill the Wicked Witch of the West,” answered Oz.

“But I cannot!” exclaimed Dorothy, greatly surprised.

“You killed the Witch of the East and you wear the silver shoes, which bear a powerful charm. There is now but one Wicked Witch left in all this land, and when you can tell me she is dead I will send you back to Kansas--but not before.”

The little girl began to weep, she was so much disappointed; and the eyes winked again and looked upon her anxiously, as if the Great Oz felt that she could help him if she would.

“I never killed anything, willingly,” she sobbed. “Even if I wanted to, how could I kill the Wicked Witch? If you, who are Great and Terrible, cannot kill her yourself, how do you expect me to do it?”
