“Well, I wish I knew what you were talking about,” said Vi plaintively, and Billie briefly told of her meeting with Miss Arbuckle in the morning and of the teacher’s grief at losing her precious album.

“Humph! I don’t see anything very precious about it,” sniffed Laura. “Look—the corners are all worn through.”

“Silly, it doesn’t make any difference how old it is,” said Vi as they started back along the path, Billie holding on tight to the book. “It may have pictures in it she wants to save. It may be—what is it they call ’em?—an heirloom or something. And Mother says heirlooms are precious.”

“Well, this isn’t a hair wreath, it’s an album,” Billie pointed out. “And I don’t blame Miss Arbuckle for not wanting to lose an album with family pictures in it.”

“Of course it is, silly,” Laura went on impatiently. “It isn’t likely that two people would be foolish enough to lose albums on the same day. If it had been a stick pin now, or a purse——”
