He took the piglets from his pocket and let them run on the grass, and Jim tasted a mouthful of the green blades and declared he was very contented in his new surroundings.

"We can't walk in the air here, though," called Eureka, who had tried it and failed; but the others were satisfied to walk on the ground, and the Wizard said they must be nearer the surface of the earth than they had been in the Mangaboo country, for everything was more homelike and natural.

"But where are the people?" asked Dorothy.

The little man shook his bald head.

"Can't imagine, my dear," he replied.

They heard the sudden twittering of a bird, but could not find the creature anywhere. Slowly they walked along the path toward the nearest cottage, the piglets racing and gambolling beside them and Jim pausing at every step for another mouthful of grass.

Presently they came to a low plant which had broad, spreading leaves, in the center of which grew a single fruit about as large as a peach. The fruit was so daintily colored and so fragrant, and looked so appetizing and delicious that Dorothy stopped and exclaimed:

"What is it, do you s'pose?"

The piglets had smelled the fruit quickly, and before the girl could reach out her hand to pluck it every one of the nine tiny ones had rushed in and commenced to devour it with great eagerness.

"It's good, anyway," said Zeb, "or those little rascals wouldn't have gobbled it up so greedily."

"Where are they?" asked Dorothy, in astonishment.

They all looked around, but the piglets had disappeared.

"Dear me!" cried the Wizard; "they must have run away. But I didn't see them go; did you?"

"No!" replied the boy and the girl, together.

"Here,—piggy, piggy, piggy!" called their master, anxiously.

Several squeals and grunts were instantly heard at his feet, but the Wizard could not discover a single piglet.

"Where are you?" he asked.

"Why, right beside you," spoke a tiny voice. "Can't you see us?"

"ARE THERE REALLY PEOPLE IN THIS ROOM?"

"No," answered the little man, in a puzzled tone.

"We can see you," said another of the piglets.

The Wizard stooped down and put out his hand, and at once felt the small fat body of one of his pets. He picked it up, but could not see what he held.

"It is very strange," said he, soberly. "The piglets have become invisible, in some curious way."

"I'll bet it's because they ate that peach!" cried the kitten.

"It wasn't a peach, Eureka," said Dorothy. "I only hope it wasn't poison."

"It was fine, Dorothy," called one of the piglets.

"We'll eat all we can find of them," said another.

"But we mus'n't eat them," the Wizard warned the children, "or we too may become invisible, and lose each other. If we come across another of the strange fruit we must avoid it."
