The "Ottawa" imprint appears three times, once in the middle of the top margin, over stamps 10 and 11, and twice in the bottom margin, beneath stamps 5 and 6, and again beneath stamps 15 and 16. There are no imprints at the sides. The denomination appears in the top margin at both right and left and in a new style of lettering on these larger plates. Thus we find ONE CENT or TWO CENT over stamps 2 and 3 as well as 18 and 19, or THREE CENT over the first four and last four stamps in plain Egyptian capitals. [Illustration] The 1/2c value, which we have left until last on account of its different sheet arrangement, had the "Montreal" imprint, described in connection with the other values, arranged six times on the margins--above and below each pane, at the right of the right hand pane, and at the left of the left hand pane--so that there were three imprints on each of the "post-office" sheets of 100 stamps. In addition, to quote Mr. Howes, "over the top inscription of the right pane is the reversed figure 1, 4 mm. high, and in the same position on the left pane the corresponding figure 2, evidently to designate the panes." This series provides a number of shade varieties, as is only natural in a set having such long currency, and their proper treatment is a matter involving some little perplexity. It was evidently the original intention of the printers to keep the colors of the small stamps as nearly like those of the large ones they superseded as possible, and while many shades match the colors of the earlier stamps to a nicety others show a divergence that at times almost approaches a "color change." As early as May, 1873, the _Stamp Collector's Magazine_ noted a change in the shade of the 3c viz.:-- By the courtesy of a Montreal correspondent we are in possession of specimens of the current three cents, printed in bright orange-vermilion. A supply in this color has just been issued. The _Philatelic Record_ for March, 1888, says "The 10c is now in carmine-red", and again in May that "the 5 cents has changed its color from bronze-green to greenish grey." More than a year later (July, 1889) the same journal says "the 2 cents stamp is now blue-green;" in December, 1890, the 6c is recorded in "chestnut-brown"; while in April, 1892, the 5c is chronicled as having been issued in "grey-black."
