"Well," Nesta remarked, again with a touch of superiority, "of course we all knew that without his telling us."

Eustace eyed her with a quietness that somehow irritated the girl. She could not understand him at all, and nothing annoyed Nesta so much as to discover she was not understanding something that was perfectly clear to somebody else.

"Didn't you know it?" she asked sharply.

"Of course," said Eustace dreamily.

"Then what do you mean?" Nesta demanded.

"I was thinking about going to England," was the seemingly irrelevant reply.

"What has that got to do with it?" said Nesta.

"Everything," Eustace said. "If we had been going to stay here for ever and ever I shouldn't have thought so much about it. As it is, it means a lot that good old Bob won't forget us."

"Why, how stupid you are to-day," Nesta exclaimed. "Did you think he might in 'a year and a day,' as mother calls it?"

"How do you know it will be only 'a year and a day'?" Eustace said almost roughly. "How do you know we shall ever come back?"
