"Were you thinking what I was?" he asked. "You know I could easily move those partitions over in the lower row of the post-office, to make it hold another box like the upper row."

"I am afraid I don't understand, Jack," said Miss Isabel.

"Why, then we could ask Mr. Dean to be an honorary member, too," explained Jack.

"Oh, yes!" cried the three girls.

"I'm sure he'd be delighted; he seemed so interested in the office," said Amy.

"Should you mind?" asked Trix. "May we?" while Margery said nothing, but looked eager.

"My dear children, you may do anything you like, and will you do one favor for me?" said Miss Isabel. "If it is not too much trouble, will one of you bring my mail to me every day? It is getting so warm, I shall not feel like going down."

"Why, we'd love to," they all cried.

"Let me do it all the time," begged Jack.

"You will all come; I want you all," said Miss Isabel, rising. "You won't mind if I say good-by? I—I feel tired. Good-night, dears; come back as soon as you can."
