With reference to what is said about the Canadian officially-sealed label in the London Society's new book, I am glad to be able to throw some light upon the question as to the manner of its employment.
When I was in Canada last July [1889] I made special enquiries about these labels, as there appeared to be some mystery about their use. Everyone agreed that they were not placed upon all letters opened at the Dead Letter Office and returned to their senders, and no two persons seemed to have quite the same theory as to the rules for their employment or non-employment in any particular case. Even gentlemen connected with the Post-Office at Halifax, such as Mr. King and others, could give me no definite information. I therefore determined to see what I could do at the head-quarters at Ottawa.
Fortunately, I was able, through a collector in an official position, to obtain an introduction to the Deputy Postmaster-General, who most kindly gave me the following particulars, which show that the employment of the officially sealed labels is very restricted, thus accounting for their rarity.
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 for reclosing them.
The labels are of relatively large size, being 25½ by 38 mm. The design is mostly engine-turned work, with the words OFFICIALLY SEALED on a label across the center; above this appears, in a curve, POST OFFICE CANADA, and beneath likewise DEAD LETTER OFFICE. The label is a fine piece of line engraving, but we have been unable to ascertain the size of
the sheets in which it was printed. Doubtless the usual four marginal imprints were employed, being the "Montreal" type in pearled border.
It seems to be the general idea that the first printing of the labels, which were in a dark red-brown, was the only one, but no information is at hand concerning the quantity delivered. At any rate in the Canadian Notes in Mekeel's Weekly Stamp News for November 30, 1892 we read that:—"From a reliable source it is learned that the old die of the Canada official seal stamp has been spoiled or rather destroyed for further use by the Bank Note Company, who have possession of it." We suggest that the words "spoiled" and "destroyed" have been transposed in the original, the meaning evidently being that the die had been defaced as of no further use.
