To prove this we take two of the latter cards (in the absence of an uncut sheet which we have never seen), place them end against end, measure the distance from the left end of the scroll on one card to the outer circle enclosing the figure "1" on the other card, and the result will be as stated above. This fact and the letter from the Canadian P. O. Department, quoted above, removes all doubts as to the true character of this rarity, known as the "Canada Error Card". We have several used specimens in our collection. The _Monthly Journal_[231] later received a copy of the error card which was postmarked in September, 1884, and which is the earliest date that has been recorded for it. [231] =Monthly Journal=, IV: 171. Direct evidence is given in a letter from H. F. Ketcheson to _Mekeel's Weekly Stamp News_; he writes as follows:[232]-- Regarding the Canadian reply card (error with stamp on upper left hand corner) issued in 1884 (not 1885) would say that I purchased a quantity of them from various post-offices. I was at that time an employe of the Canada Post-Office Department and saw a number of these passing through the mails and writing to the offices at which they were posted found that they had received a supply from Ottawa, and one office informed me at the same time that they had re-received instructions to forward all they had on hand to Ottawa as they had been issued in error. [232] =Mekeel's Weekly Stamp News=, VI: 216. The cards were identical in every respect with the regular ones, except for the peculiarity, and therefore call for no further description than has already been given them. [Illustration]
