le over the edge of the roof. It seemed firm
enough to walk upon, so he took courage and put out the other foot.
Dorothy kept hold of his hand and followed him, and soon they were both
walking through the air, with the kitten frisking beside them.

"Come on, Jim!" called the boy. "It's all right."

Jim had crept to the edge of the roof to look over, and being a
sensible horse and quite experienced, he made up his mind that he could
go where the others did. So, with a snort and a neigh and a whisk of
his short tail he trotted off the roof into the air and at once began
floating downward to the street. His great weight made him fall faster
than the children walked, and he passed them on the way down; but when
he came to the glass pavement he alighted upon it so softly that he was
not even jarred.

"Well, well!" said Dorothy, drawing a long breath, "What a strange
country this is."

People began to come out of the glass doors to look at the new
arrivals, and pretty soon quite a crowd had assembled. There were men
and women, but no children at all, and the folks were all beautifully
formed and attractively dressed and had wonderfully handsome faces.
There was not an ugly person in all the throng, yet Dorothy was not
especially pleased by the appearance of these people because their
features had no more expression than the faces of dolls. They did not
smile nor did they frown, or show either fear or surprise or curiosity
or friendliness. They simply started at the strangers, paying most
attention to Jim and Eureka, for they had never before seen either a
horse or a cat and the children bore an outward resemblance to
themselves.

Pretty soon a man joined the group who wore a glistening star in the
dark hair just over his forehead. He seemed to be a person of
authority, for the others pressed back to give him room. After turning
his composed eyes first upon the animals and then upon the children he
said to Zeb, who was a little taller than Dorothy:

"Tell me, intruder, was it you who caused the Rain of Stones?"

For a moment the boy did not know what he meant by this question.
Then, remembering the stones that had fallen with them and passed them
long before they had reached this place, he answered:

"No, sir; we didn't cause anything. It was the earthquake."

The man with the star stood for a time quietly thinking over this
speech. Then he asked:

"What is an earthquake?"

"I don't know," said Zeb, wh
