"Why, it's a great deal for Uncle Hugson, but not for me. I'm a splendid worker. I work as well as I sleep," he added, with a laugh.

"What is your name?" said Dorothy, thinking she liked the boy's manner and the cheery tone of his voice.

"Not a very pretty one," he answered, as if a little ashamed. "My whole name is Zebediah; but folks just call me 'Zeb.' You've been to Australia, haven't you?"

"Yes; with Uncle Henry," she answered. "We got to San Francisco a week ago, and Uncle Henry went right on to Hugson's Ranch for a visit while I stayed a few days in the city with some friends we had met."

"How long will you be with us?" he asked.

"Only a day. Tomorrow Uncle Henry and I must start back for Kansas. We've been away for a long time, you know, and so we're anxious to get home again."

The boy flicked the big, boney horse with his whip and looked thoughtful. Then he started to say something to his little companion, but before he could speak the buggy began to sway dangerously from side to side and the earth seemed to rise up before them. Next minute there was a roar and a sharp crash, and at her side Dorothy saw the ground open in a wide crack and then come together again.
