Letters in Canada, as in the United States, very frequently have on the outside the well-known notice containing the address of the sender, and a request that the letter may be returned if not delivered within a certain time. These, of course, are not opened at the Dead Letter Office, and in fact, I think, are ordered not to be sent there, but are returned direct from the office to which they were originally addressed or from the head office of the district. On the other hand, those that have no indication of the address of the sender on the outside are sent to the Dead Letter Office, and there necessarily opened; but neither of these classes thus properly dealt with is considered to require the _officially-sealed label._ It is only if one of the former class, having the sender's name and address on the outside, is sent to the Dead Letter Office and there opened in _error_ that the _officially-sealed_ label is applied, to show that such letter has been opened officially, and not by any unauthorized person. Whether these pieces of gummed paper ever had a more extended use or not I cannot say, but I was assured that the above was the substance of the regulations as to their employment. The Deputy Postmaster-General further stated that there had been so many requests for specimens of these labels that the Department had been obliged to make it a rule to turn a deaf ear to all of them. In any case they are not _postage stamps_, properly speaking, at all. They indicate neither postage paid nor postage due, but simply that the letters to which they are attached have been opened by proper authority, and they at the same time afford a means of reclosing them. About 1905 a label of new design was introduced, this, of course, being the work of the American Bank Note Company. These are larger than their predecessors and are very handsome labels. In the centre is an excellent portrait of Queen Victoria, adapted from the "Law Stamps" of 1897, with "CANADA" in heavy uncolored Roman capitals curved above, and, at the top, the words "OFFICIALLY SEALED" in letters so graded that the tops form a straight line, while the bottoms follow the curve of "CANADA". Under the portrait the words "DEAD LETTER" are shown on a straight label which extends right across the stamp, while below this is the word "OFFICE" on a curved tablet. The spaces at the sides and the bottom are filled with elaborate foliate ornaments and engine-turned work. These labels are also perforated 12 and exist on two kinds of paper. Until about 1907 the paper was of a pale blue color while subsequent printings have been on ordinary white paper. _Reference List._ 1879. Engraved and printed by the British American Bank Note Co.
