"Why don't you walk down?" asked Eureka. "I'm as hungry as the horse is, and I want my milk."

"Will you try it, Zeb" asked the girl, turning to her companion.

Zeb hesitated. He was still pale and frightened, for this dreadful adventure had upset him and made him nervous and worried. But he did not wish the little girl to think him a coward, so he advanced slowly to the edge of the roof.

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. 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 stared 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?"
