"Now, however, I tell you plainly that I alter all my tactics. One girl sitting in this room is guilty. For her sake I shall treat you all as guilty, and punish you accordingly. For the remainder of this term, or until the hour when the guilty girl chooses to release her companions, you are all, with the exception of the little children and Miss Russell, who can scarcely have played this trick on herself, under punishment. I withdraw your half-holidays, I take from you the use of the south parlor for your acting, and every drawing-room in the play-room is confiscated. But this is not all that I do. In taking from you my trust, I must treat you as untrustworthy--you will no longer enjoy the liberty you used to delight in--everywhere you will be watched. A teacher will sit in your play-room with you, a teacher will accompany you into the grounds, and I tell you plainly, girls, that chance words and phrases which drop from your lips shall be taken up, and used, if necessary, to the elucidation of this disgraceful mystery."
