The same journal, two months later, made more extended reference to this variety and while its bona-fides as a "split" is established its use as a half stamp is as much a mystery as ever. We cannot do better than give the paragraph in full:-- In the New Issues column of our number for April, we called in question the character of a supposed "split" _three pence_ stamp of Canada, which had been chronicled in the _Post Office_, New York. In reply to our criticism, Messrs. Morgenthau & Co., the publishers of that magazine, have most kindly forwarded to us the letter bearing the divided stamp, and have requested our opinion upon it. The specimen is such a curious one and presents, we think, such a puzzle for philatelists, that we have taken the liberty--which we hope its owner will pardon--of having a photographic block made from it, and we give a full size illustration, showing both the stamps and the postmarks, herewith. As our readers may perceive, we were quite wrong in suggesting that the "split" stamp was merely a badly cut copy, as it appears to have been carefully bi-sected diagonally and to have been intended to pass as a half stamp, making up, with the entire stamp to which it is attached, a rate of 4-1/2d. If this were all, though the specimen would be a great rarity--indeed, we believe it to be unique--it would not be necessarily a great puzzle to us. It is true that we do not know of any 4-1/2d rate in Canada, and there never was a 4-1/2d stamp in use there; but still, such a rate might have existed, although there was no possible means of making it up except by the use of at least three 1/2d stamps; but the puzzling part about this letter is that it is addressed from Port Hope in Canada to New York, the single rate from Canada to the United States was 10 cents; the letter is marked "CANADA--_PAID 10 Cts_." by the side of the stamps, and that rate was sixpence in Canadian currency. The whole document appears to us to be perfectly genuine and _bona-fide_; we have examined it with a skeptical mind and a powerful magnifying glass, and we can only say that if it is a "fake" it is wonderfully well done. On the other hand, if it is genuine, the half stamp must have done duty as a whole one, because it certainly took two 3d stamps to make up the 10 cents rate. The puzzle remains a puzzle to us, but we are grateful to Messrs. Morgenthau for their courteous reply to what may have appeared a captious criticism. _Reference List._ 1851.
