"A sawhorse is a thing they saw boards on," remarked Jim, with a sniff.

"It is when it's not alive," acknowledged the girl. "But this sawhorse can trot as fast as you can, Jim; and he's very wise, too."

"Pah! I'll race the miserable wooden donkey any day in the week!" cried the cab-horse.

Dorothy did not reply to that. 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 wink."

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.

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 Oz, the Wonderful Wizard, come back again!"

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," said the soldier; "but I shaved them off long ago, and since then I have risen from a private to be the Chief General of the Royal Armies."

"That's nice," said the little man. "But I assure you, my good people, that I do not wish to rule the Emerald City," he added, earnestly.

"In that case you are very welcome!" cried all the servants, and it pleased the Wizard to note the respect with which the royal retainers bowed before him. His fame had not been forgotten in the Land of Oz, by any means.

"Where is Dorothy?" enquired Zeb, anxiously, as he left the buggy and stood beside his friend the little Wizard.

"She is with the Princess Ozma, in the private rooms of the palace," replied Jellia Jamb. "But she has ordered me to make you welcome and to show you to your apartments."

The boy looked around him with wondering eyes. Such magnificence and wealth as was displayed in this palace was more than he had ever dreamed of, and he could scarcely believe that all the gorgeous glitter was real and not tinsel.

"What's to become of me?" asked the horse, uneasily. He had seen considerable of life in the cities in his younger days, and knew that this regal palace was no place for him.

It perplexed even Jellia Jamb, for a time, to know what to do with the animal. The green maiden was much astonished at the sight of so unusual a creature, for horses were unknown in this Land; but those who lived in the Emerald City were apt to be astonished by queer sights, so after inspecting the cab-horse and noting the mild look in his big eyes the girl decided not to be afraid of him.

"There are no stables here," said the Wizard, "unless some have been built since I went away."

"We have never needed them before," answered Jellia; "for the Sawhorse lives in a room of the palace, being much smaller and more natural in appearance than this great beast you have brought with you."

"Do you mean that I'm a freak?" asked Jim, angrily.

"Oh, no," she hastened to say, "there may be many more like you in the place you came from, but in Oz any horse but a Sawhorse is unusual."

This mollified Jim a little, and after some thought the green maiden decided to give the cab-horse a room in the palace, such a big building having many rooms that were seldom in use.

So Zeb unharnessed Jim, and several of the servants then led the horse around to the rear, where they selected a nice large apartment that he could have all to himself.

Then Jellia said to the Wizard:

"Your own room—which was back of the great Throne Room—has been vacant ever since you left us. Would you like it again?"

"Yes, indeed!" returned the little man. "It will seem like being at home again, for I lived in that room for many, many years."

He knew the way to it, and a servant followed him, carrying his satchel. Zeb was also escorted to a room—so grand and beautiful that he almost feared to sit in the chairs or lie upon the bed, lest he might dim their splendor. In the closets he discovered many fancy costumes of rich velvets and brocades, and one of the attendants told him to dress himself in any of the clothes that pleased him and to be prepared to dine with the Princess and Dorothy in an hour's time.

Opening from the chamber was a fine bathroom having a marble tub with perfumed water; so the boy, still dazed by the novelty of his surroundings, indulged in a good bath and then selected a maroon velvet costume with silver buttons to replace his own soiled and much worn clothing. There were silk stockings and soft leather slippers with diamond buckles to accompany his new costume, and when he was fully dressed Zeb looked much more dignified and imposing than ever before in his life.

He was all ready when an attendant came to escort him to the presence of the Princess; he followed bashfully and was ushered into a room more dainty and attractive than it was splendid. Here he found Dorothy seated beside a young girl so marvelously beautiful that the boy stopped suddenly with a gasp of admiration.
