Without doubt M. Moens gave the correct explanation, for the imprint that he mentions will be recognized as the one to be found on the earliest plates of the small stamps, and 1888 was thirteen years at least after the second type of imprint with "Montreal" only had been introduced. Hence the stamp in question was probably a late print from a worn plate, which gave a rather flat and indistinct impression that might suggest lithography, though it is certain that Canada has never yet stooped to such a cheap means of postage stamp production. A similar case may be recalled with the 1/2 penny stamp of St. Helena which was issued in 1884, and which presented a like appearance. Whether the above incident had anything to do with the change of the printing company from Montreal to Ottawa, which we have already noted in describing the imprints, we cannot say, but it is certain that it was the beginning of changes, in shade at least, which affected the whole series of stamps. We have the authority of the Postmaster General's Report for 1889 that the "removal of the British American Bank Note Co. from Montreal to Ottawa" had taken place--evidently early in 1888, as will be seen later--so that the use of an old worn-out plate might have been a case of temporary necessity. Further details are given by the Canadian correspondent of the _Weekly Philatelic Era_[107] as follows: "About six years ago the Government insisted on their contractors doing their printing at the Capital, and the British American Bank Note Co. erected a handsome establishment on Wellington Street, where all postage stamps have since been printed. It may be remembered that the Ottawa printings were signalized by distinct varieties in shade from the earlier Montreal issues, varieties that have never been sufficiently distinguished in the standard catalogues." [107] =Weekly Philatelic Era=, XII: 23. These changes in the stamp shades were soon noted. In March, 1888, the _Philatelic Record_ described the 10 cent stamp as "now in carmine-red", while two months later it chronicled the 5 cent as changed "from bronze-green to greenish-grey." We have already noted the change in the 15 cent to a color approximating its original mauve, "only more of a bluish tinge," which the _Halifax Philatelist_ recorded in July, 1888. The following October the same paper listed the 3 cent in a "bright carmine", and in July, 1889, announced the 2 cent in "blue green". The 6 cent lagged behind the others and did not manifest itself until the _American Journal of Philately_ announced it in October, 1890, in a "rich brown." Once again, _Le Timbre-Poste_ for April, 1892, stated that the 5 cent had "since the 8th March, appeared in gray black". The 1 cent doubtless had its special hue of yellow along with the other changes, but it was not recorded, probably because not distinct enough from the usual run of variations in which it had been appearing.
