Plate impression, 19½ by 25 mm., in color, on white paper, perforated 12.
7 cents, vermilion.
All these values were first issued with a grille, of which there are several sizes, but on many, if not most, even of unused specimens it is so indistinct that it is impossible to distinguish the outlines, measure the size, or count the squares. Some very perfect unused specimens have been examined however, and on the face it appears to be composed of horizontal rows of depressed diamonds, divided by alternate rows of smaller raised diamonds, with deep-depressed lines along the sides of the latter. On the reverse, the appearance is of rows of squares divided by depressed lines, with little raised crosses in each square. By these specimens it has also been determined, that there were at least two distinct sizes of grille.
The first measures 10½ by 12½ mm., composed of 13 by 15½ rows of squares. Perfect specimens of the 1, 2, 3, 7 and 10 cent so grilled, have been found, and satisfactory specimens of the 6, 12, 15, 24, 30 and 90 cents.
The other variety measures 8½ by 10½ mm., and is composed of 10 by 13 rows of squares. Perfect specimens of the 1, 2, 3 and 7 cents so grilled have been found, but no satisfactory specimens of any other value.
Specimens with only a few distinct squares, are comparatively common.
The difficulty of arriving at accurate measurement, is increased when the specimens examined have been used, but apparently the larger of the above grilles was gradually cut down row by row to the smaller, as specimens of the 1, 2 and 3 cents, the most used values, are found undoubtedly grilled.

These all now bear a deep yellow or brown gum. The colors are very uniform.
As stated by the passage quoted above, there are 100 stamps, or ten rows of ten stamps in the so called sheet, or properly half sheet, there being 200 on the plate. The imprint was either "Engraved and printed by the," in one line, "National Bank Note Co., New York," in a second line in colorless capitals, on a solid ground, with pearled edges and outer fine colored line, or the second line above without pearls on colored ground, bordered by a double colored line. The author cannot state whether all the values bore both imprints, having only seen the 1, 2 and 3 cents with the first, and the 30 and 90 with the second, the latter without the grille. These imprints are placed 2 mm. from the stamps, above and below the 5th and 6th rows on each half sheet, the plate number being between the 8th and 9th rows. The line on which the sheets are divided is indicated by three lines forming a sort of arrow head, at the top and bottom of the sheet. The center rows of stamps are 2½ mm. apart, and there are no perforations between them. The vertical rows of perforation are 22½ mm. apart horizontally. The horizontal rows 27½ mm. apart vertically, but the upper and lower rows are sometimes 28½ and sometimes 29½ mm. apart. If a sheet is selected, where the vertical rows are so far from the center line as to cut into the stamps, and the horizontal rows too high or too low, and a stamp from the top or bottom of the row next to the center cut line is selected, and the perforations carefully cut off, specimens can be made that have a much larger margin than the ordinary perforated stamps, and might easily pass as unperforated. This may not account for all the unperforated specimens, some of which may be the result of accident, but all the values of this series and the following may be so made unperforated, and have been so catalogued.
