Illustrations Nos. 18 and 19 show the work of the B machine. No. 18 is a group of four of the Four Pence of 1866, and No. 19 a group of four of the One Penny of 1880. These groups speak for themselves, both as regards the irregularity in the spacing of the holes, and the different character of the perforation at the two mentioned dates. In No. 18, in the central vertical line, the space separating the second and third holes, counting from the bottom, may be contrasted with that between the eleventh and twelfth in the same line, as this affords a good example of the irregularity of the machine, and a little search will yield many more such examples, both in No. 18 and in No. 19. No. 20 is a group of four of the Six Pence of 1877, and shows the compound perforation B×A. In this case the later work of both machines appears. We should have liked to have been able to illustrate the compound perforation as it appears in 1866, when the machines made lines of holes as in illustrations No. 16 and No. 18. The only stamp available for this purpose would have been the One Shilling of 1866, but we have been unable to procure a group of four of these for illustration. No. 21, which shows the De La Rue perforation 12, has been given so as to allow of its comparison with the early work of the B machine, as shown in No. 18, as it approximates to it in gauge, is like it in character, and even faintly imitates its irregularities. We shall revert to this perforation in our notes to the Issues of Section II. Issue 1. _May 1861._ 1d., bright rose-red, many shades from pale to deep. 6d., blue-green, slight shades from medium to dark. These two values constitute the first issue for St. Vincent. They were printed by Messrs. Perkins, Bacon & Co., and sent out to the Colony on March 27th, 1861, the consignment consisting of 934 sheets of the One Penny, and 167 sheets of the Six Pence.[5] Both values were printed from plates engraved in _taille-douce_, each plate consisting of 60 stamps, arranged in six horizontal rows of ten. The paper used was without watermark, either for the stamps themselves or in the margins, and at least two very distinct sets can be made, one on thick and the other on much thinner paper. The texture is rough, and the colour greyish, sometimes slightly toned by the yellowish gum. There can be no reasonable doubt that the perforation of the first consignment was A, for although we have no direct evidence to that effect, any supposition other than this would involve us in such contradictions that our belief on this point amounts to what is practically a certainty.
