in order that they may be returned to the writers, provided any clue can be obtained from the contents as to their whereabouts. The branch in which this work is accomplished is now a very considerable establishment, employing at least a score more clerks, &c. than in the days of the old postage. In 1763, just a hundred years ago, the records show that two clerks only were engaged in opening "_dead and insolvent letters_." Now, nearly fifty officers are employed in the same duties. Nor are these duties by any means so only in name. Last year considerably over two millions of letters were returned to their writers through the Dead-Letter Office from failures in the attempts to deliver them. "Three-quarters of the non-deliveries," says the Postmaster-General, "were on account of the letters being insufficiently or incorrectly addressed, nearly 11,000 letters having been posted _without any address at all_." In every provincial post-office in England and Wales a dead or returned letter-bag is now forwarded daily to London, containing all the letters which, from any cause, cannot be delivered. Each letter bears on its front, written prominently in red ink, the reason of its non-delivery. Thus, if the addressee cannot be found, or should have left the town, the words "Cannot be found," or "Gone--left no address," are written respectively. On the arrival of these bags in London, inclosed in the larger bags containing the general correspondence, they are at once passed to the "returned-letter branch," as the Dead-Letter Office is called, where no time is lost in opening them. Every letter received is first examined by an experienced and responsible officer, to make sure that it has been actually presented according to its address, and that the reasons assigned on the cover of the letter are sufficient to account for its non-delivery. In doubtful cases, before the letter is opened, the directories and other books of reference, of which there is a plentiful supply in this office, are consulted, and should it be found or thought that there has been any oversight or neglect, the letter is re-issued, with proper instructions, by the first post. About 300 letters are thus re-issued daily, many of which ultimately reach the persons for whom they are intended.
