In further support of the above postulates, we must say that every cover bearing any one of the three perforated stamps which we have been able to get a satisfactory date from has been postmarked in _1859_! Not one has yet been seen which bore a date in 1858 even, and one 6d. from the Seybold collection, which was dated at Brantford, Dec. 29, 1857, turned out to be bad. Of course perforated pence stamps are hard to find on original covers, but it is curious that so far not one has upset the theory we have laid down. There is one point left which perhaps needs some attention. The London Society's work lists a 6d. on _laid_ paper, perforated 12, and Mr. King has followed by including it in his reference list. This would imply that the Canadian Government had perforated its stock on hand, in which might be a few remainders of the early laid paper issue, and naturally would go far toward confirming that view of the origin of the perforated series. But this stamp seems to be an unknown quantity, almost as much so as the 3d. "perforated 13" of Major Evans' Catalogue. Mr. Pack says:[72]--"I have never heard of the 6d. perforated, on laid paper. It is catalogued in the Society's publication, but a copy, so far as I can learn, has never been seen in Canada or in the United States." [72] =London Philatelist, XVI=: 144. We have been interested to track this stamp, and have apparently found the original located in the Tapling collection, now housed at the British Museum. In a catalog of the Canadian portion of this collection by Gordon Smith,[73] we find two unused copies listed on _laid_ paper, one marked "perf. 12" and the other "forged perf." The sequel is found in the _American Journal of Philately_ for 1891[74] in the following note:-- There is no longer any mystery in regard to the origin of that _great rarity_! the perforated 6 pence on laid paper, these stamps having been perforated for four or five years in the shops of Messrs. Benjamin Sarpy & Co., Cullum street, London, who openly boast of having manufactured and sold those in the collection of the late Hon. T. K. Tapling and other prominent collectors.
