That the above changes were hardly of a character to warrant dignifying them as a "new issue," which is frequently done, is shown by a moment's consideration. The 1/2 cent and 1 cent stamps showed no appreciable difference in coloring and therefore caused no comment. The 2 cent did not maintain its blue green shade unaltered, and the 3 cent soon reverted to its former brilliant red hue, as the _Philatelic Journal of America_ for May, 1889, says that "the carmine color recently adopted has been dropped, and the stamps are printed in colors similar to the ones in use before the change was made." The 5, 6 and 10 cent stamps, however, made permanent changes, but only such as might readily be traceable to a new mixing of the inks in the case of the first two. The 10 cent can hardly be so easily disposed of, as lake and brown-red are of quite different composition from a rose-lilac. But there can have been no official intention of altering the shades or colors or more definite and permanent changes would certainly have been made throughout the set. It remains, therefore, to classify them simply as shade varieties of the original set. Mr. King gives a list of eight varieties of paper[108] for the "small cents issues", but we have deemed it sufficient to note a thick and a thin white wove paper, and a closely ribbed paper. All values are reported as existing with the compound perforation (11-1/2 × 12) spoken of under the 1868 issue. We also find all values occurring in an imperforate condition. The 3 cent was first noted in the _Philatelic Record_ for December, 1882; the 15 cent we have already spoken of under the 1868 issue; and the 5, 6 and 10 cent at least, from the shades of the specimens we have seen, belong to the printings subsequent to the color modifications of 1888-90. Concerning these imperforates, we find in a paper on Canada, read before the Royal Philatelic Society by Mr. M. H. Horsley,[109] the following note:-- In my opinion, which I have had confirmed by several most competent authorities, the various imperforated copies which I show you, some used and some unused, are absolutely genuine varieties. Imperforated copies of various values were sold over the Post-office counter in Montreal about the years 1891-3, at their face value, and have been good for postage whenever people cared to use them. The quantities in this condition are, I believe, extremely small. [108] =Monthly Journal=, VIII: 237. [109] =London Philatelist=, XVI: 88. Supplementing this Mr. Pack writes:[110]-- I quite agree with Mr. Horsley in regard to the various imperforate copies of the issues of 1882 to 1895. There are a good many specimens of these stamps imperforate, and they were on sale at a Canadian Post Office. [110] =London Philatelist=, XVI: 144.
