Having looked at a few more of the letters that were then passing under examination, Mr Bright showed them a book in which were copied facsimiles of addresses which had passed through the post. Some of these were pictorial--embracing quaint devices and caricatures, most of them in ink, and some in colours, all of which had been traced by a gentleman in the office with great skill. One that struck May as being very original was the representation of an artist painting the portrait of the Queen. Her Majesty was depicted as sitting for her portrait, and the canvas on the easel before which the artist stood was made the exact size of the postage-stamp. While the ladies were examining this book of literary curiosities, Mr Bright took occasion to comment with pardonable pride on the working of the Post-Office. "You see, ma'am," he said, "we do our best for the public--though many of 'em have no idea of it. We don't send letters to the Returned Letter Branch till we've tried, as you see, to get the correct addresses, and until two separate letter-carriers have attempted to deliver them. After leaving the letter-carriers' hands, the address of every undelivered letter, and the indorsement it bears, are carefully examined by a superior officer, who is held responsible for discovering any wrong treatment it may have undergone, and for having recourse to any further available means of finding the owner. It is considered better that the sender of a letter should know as soon as possible of its non-delivery, than that it should travel about with little prospect of its owner being found. We therefore send it to the Returned Branch without further delay, where it is carefully examined by a superior officer, to see that it has actually been presented as addressed, and that the reasons assigned for its non-delivery are sufficient. In doubtful cases the Directories and other books of reference in the branch are consulted, and should it be found that there has been any oversight or neglect, the letter is immediately re-issued. After all has been done that can be to deliver such letters, they are opened, and returned the same day to the senders. If valuables are enclosed, the address and contents are recorded in case of inquiry. When senders fail to give their addresses, sometimes these are discovered by bills of exchange, cheques, or money-orders, which happen to be enclosed. When addresses of senders can be discovered by information on the outside of covers, the letters are returned without passing through the Returned Letter Branch, and are not opened. When all efforts have failed, and the letters do not contain property, they are not preserved." "Do many letters come into the Returned Letter Offices in this way?" asked Miss Lillycrop.
