'Girls,' she began, with an air almost of tragedy, 'a very distressing incident has happened to-day--a circumstance which in all the records of this school has never occurred before. You see this book in my hand,' and she held up (oh, luckless Peggy!) the missing note-book. 'This book of manuscript notes, which I had compiled myself from various sources, and valued greatly, I lent to be copied by the third form. It was lost, and though I caused every search to be made, I could find no trace of it. Girls, I regret to say that to-day this book has been brought back to school, and _has been placed in another girl's desk_--in the desk, I repeat, of an innocent girl, who had nothing to do with its loss.'
