She felt that Jim would know more about
the Saw-Horse later on.

The time dragged wearily enough to the eager watchers, but finally the
Wizard announced that four o'clock had arrived, and Dorothy caught up
the kitten and began to make the signal that had been agreed upon to
the far-away invisible Ozma.

"Nothing seems to happen," said Zeb, doubtfully.

"Oh, we must give Ozma time to put on the Magic Belt," replied the girl.

She had scarcely spoken the words then she suddenly disappeared from
the cave, and with her went the kitten. There had been no sound of any
kind and no warning. One moment Dorothy sat beside them with the
kitten in her lap, and a moment later the horse, the piglets, the
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 sure he was not asleep. For they were in the streets of a
beautiful emerald-green city, bathed in a grateful green light that was
especially pleasing to their eyes, and surrounded by merry faced people
in gorgeous green-and-gold costumes of many extraordinary designs.

Before them were the jewel-studded gates of a magnificent palace, and
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.

Zeb shook the reins to rouse the cab-horse from his stupor of
amazement, for the people were beginning to gather around and stare at
the 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.

15. Old Friends are Reunited

Many servants dressed in handsome uniforms stood ready to welcome the
new arrivals, and when the Wizard got out of the buggy a pretty girl in
a green gown cried out in surprise:

"Why, it's
