e Wizard and the
boy were all that remained in the underground prison.

"I believe we will soon follow her," announced the Wizard, in a tone of
great relief; "for I know something about the magic of the fairyland
that is called the Land of Oz. Let us be ready, for we may be sent for
any minute."

He put the piglets safely away in his pocket again and then he and Zeb
got into the buggy and sat expectantly upon the seat.

"Will it hurt?" asked the boy, in a voice that trembled a little.

"Not at all," replied the Wizard. "It will all happen as quick as a

And that was the way it did happen.

The cab-horse gave a nervous start and Zeb began to rub his eyes to make

emerald-green city, bathed in a grateful green light that was especially

now the gates opened slowly as if inviting them to enter the courtyard,
where splendid flowers were blooming and pretty fountains shot their
silvery sprays into the air.

strangers.

"Gid-dap!" cried the boy, and at the word Jim slowly trotted into the
courtyard and drew the buggy along the jewelled driveway to the great
entrance of the royal palace.

The little man looked at her closely and then took both the maiden's
hands in his and shook them cordially.

"On my word," he exclaimed, "it's little Jellia Jamb--as pert and pretty
as ever!"

"Why not, Mr. Wizard?" asked Jellia, bowing low. "But I'm afraid you
cannot rule the Emerald City, as you used to, because we now have a
beautiful Princess whom everyone loves dearly."

"And the people will not willingly part with her," added a tall soldier
in a Captain-General's uniform.

The Wizard turned to look at him.

"Did you not wear green whiskers at one time?" he asked.

"Yes," sa
