"That was an awful big quake," replied Zeb, with a white face.
Zeb shook the reins and urged him to go, but Jim was stubborn.
This splendid group of colored suns sent rays darting in every direction, and as the horse and buggy--with Dorothy and Zeb--sank steadily downward and came nearer to the lights, the rays began to take on all the delicate tintings of a rainbow, growing more and more distinct every moment until all the space was brilliantly illuminated.
Then she looked at Zeb, whose face was blue and whose hair was pink, and gave a little laugh that sounded a bit nervous.
Dorothy and Zeb looked at one another in wonder.
Zeb gave a shiver.
"We've got to come to the bottom some time," remarked Zeb, with a deep sigh.
But don't let us worry over such things, Zeb; we can't help ourselves just now, you know, and I've always been told it's foolish to borrow trouble.
Jim the horse had seen these spires, also, and his ears stood straight up with fear, while Dorothy and Zeb held their breaths in suspense.
"It's all wrong," said Zeb, gravely.
Zeb drew back with a shiver.
"Will you try it, Zeb?" asked the girl, turning to her companion.
Dorothy stretched out a hand to him and Zeb put one foot out and let it rest in the air a little over the edge of the roof.
"I don't know," said Zeb, who was still confused.
Dorothy and Zeb jumped out of the buggy and ran after them, but the Sorcerer remained calmly in his throne.
A balloon meant to her some other arrival from the surface of the earth, and she hoped it would be some one able to assist her and Zeb out of their difficulties.
"Who did you say it was?" whispered Zeb to the girl.
So he followed the Prince into the great domed hall, and Dorothy and Zeb came after them, while the throng of people trooped in also.
No one did, because the Mangaboos did not wear hats, and Zeb had lost his, somehow, in his flight through the air.
Dorothy and Zeb now got out of the buggy and walked beside the Prince, so that they might see and examine the flowers and plants better.
No one now seemed to pay any attention to the strangers, so Dorothy and Zeb and the Wizard let the train pass on and then wandered by themselves into the vegetable gardens.
"That's true," said Zeb, thoughtfully.
With this he began walking in the air toward the high openings, and Dorothy and Zeb followed him.
"Why, there seems to be no night at all in this country," Zeb replied.
The little man, having had a good sleep, felt rested and refreshed, and looking through the glass partition of the room he saw Zeb sitting up on his bench and yawning.
"Zeb," said he, "my balloon is of no further use in this strange country, so I may as well leave it on the square where it fell.
Just then his eye fell upon the lanterns and the can of kerosene oil which Zeb had brought from the car of his balloon, and he got a clever idea from those commonplace things.
As soon as the little girl knew what had happened she awakened the Wizard and Zeb, and at once preparations were made to go to the rescue of Jim and the piglets.
The Wizard carried his satchel, which was quite heavy, and Zeb carried the two lanterns and the oil can.
Dorothy hopped inside the opening to escape being pricked, and Zeb and the Wizard, after enduring a few stabs from the thorns, were glad to follow her.
"That's the way I feel about it," remarked Zeb, rubbing his wounds.
Zeb struck a match and lighted one of the lanterns.
But they kept steadily moving, and just as Jim was about tired out with his long journey the way suddenly grew lighter, and Zeb put out the lanterns to save the oil.
"It's good, anyway," said Zeb, "or those little rascals wouldn't have gobbled it up so greedily."
"How funny!" exclaimed Dorothy, who with Zeb and the Wizard now stood in the doorway.
As he spoke the voice came so near to Zeb that he jumped back in alarm.
Oh, I guess Zeb could fight if he had to.
Couldn't you, Zeb? asked the little girl.
"Perhaps; if I had to," answered Zeb, doubtfully.
The Wizard got out his sword at once, and Zeb grabbed the horse-whip.
The girl took a leaf and rubbed it upon the kitten's paws, and the rest of the plant was handed to Zeb, who, after applying it to his own feet, carefully rubbed it upon all four of Jim's hoofs and then upon the tires of the buggy-wheels.
As soon as he trotted out upon the surface of the river he found himself safe from pursuit, and Zeb was already running across the water toward Dorothy.
