As stated in our note to Issue 1, it is quite possible that some of the consignments belonging to this issue, at any rate of the Six Pence, contained a sheet or sheets that missed being perforated. Issue 4. _August 1866._ 4d., deep bright blue. 1s., dark slate-grey; slight shades. 1s., greyish-purple. The plates for these two values were prepared by Messrs. Perkins, Bacon & Co., early in July, 1866. They contained 30 stamps, arranged in three horizontal rows of 10, so were just half the size of those used for printing the One Penny and Six Pence values. On July 28th a consignment of stamps printed from them was sent out to the Colony. This consisted of 500 sheets of each of the values; that is, 15,000 stamps of each denomination. The stamps must have been immediately put in issue, as they were in use in August. They were chronicled in October, both by the _Timbre-Poste_ and the _Stamp Collector’s Magazine_. The notice in the latter is as follows: “Within the last month or six weeks the number of St. Vincent stamps has been doubled by the emission of a Four Penny, blue, and Shilling, purple-black.” In the _Timbre-Poste_ the colour of the Shilling is called “_pourpre_,” but in the same publication of April, 1867, M. Moens calls the colour “_ardoise_.” There is a further notice touching these stamps in the _Stamp Collector’s Magazine_ of December, 1866, which is worth quoting _in extenso_, as it is a valuable contribution to our knowledge as regards both the colours and perforations of the stamps: “The newly-issued Four Pence and One Shilling have come over with the late mails in entire sheets. The colour of the former is a clear Prussian-blue, while the latter varies, one sheet we have examined being a purple, while the other is a deep slate without the tinge of red in it, which makes a purple. The normal colour is evidently one which requires great nicety in manipulation, a slight difference in mixing forming the two shades, which are very distinct. Like the Penny and Six Pence already known these stamps are on thin woven paper, without watermark, and perforated. The Four Pence is perforated by a machine which removes a little circular piece of the paper, like that in use for the English stamps, but the holes very much wider apart. The sheets of the Shilling stamps are also perforated by a machine, and show the following remarkable peculiarity in the perforation: the horizontal lines which sever the stamps from the rows above and beneath them are, as in the Four Pence, perforated by a succession of small circular holes cut or punched out, but the vertical lines dividing the stamps from their fellows side by side in the row are perforated (if that term be quite accurate) by an instrument fixed in the machine, which leaves a series of indentations much closer than the holes before alluded to, and which does not remove a particle of paper, except in a very occasional spot, hardly one in a thousand.
