It frequently happens, either through misdirection or carelessness, that the wrong letters are left in a man's room, where they remain for a number of days without any effort on the part of the receiver to return them to the post office or to their rightful owner. We do not intend to blame the postman who discharges his duties in a perfectly satisfactory manner. When, however, we think of the large amount of mail which passes daily through his hands, there is little wonder that occasionally letters find their way into the wrong rooms. Besides, as we have said above, the letters are frequently misdirected. Now it is only right that every man, when such mistakes occur, should rectify them as soon as possible. Let no one allow a misdirected letter to lie for days on his desk, but let him return it immediately to the post office or to the person to whom it was written. We feel sure that a little care and promptness on the part of the students would prevent any annoyance from all such unavoidable mistakes as must sometimes arise.
