Mombi obeyed.

“What is the color of my pearl?” demanded Glinda.

“Why—it is black!” replied the old Witch, in a tone of wonder.

“Then you have told me a falsehood!” cried Glinda, angrily. “Only when the truth is spoken will my magic pearl remain a pure white in color.”

Mombi now saw how useless it was to try to deceive the Sorceress; so she said, meanwhile scowling at her defeat:

“The Wizard brought to me the girl Ozma, who was then no more than a baby, and begged me to conceal the child.”

“That is what I thought,” declared Glinda, calmly. “What did he give you for thus serving him?”

“He taught me all the magical tricks he knew. Some were good tricks, and some were only frauds; but I have remained faithful to my promise.”

“What did you do with the girl?” asked Glinda; and at this question everyone bent forward and listened eagerly for the reply.

“I enchanted her,” answered Mombi.
