The one, three, five, ten and twelve cent values were first made by perforating sheets from the original plates, and later, certain changes were made that require to be noticed.

The first perforated sheets being from the same plates as the unperforated, the same observations apply to them. It is to be noticed that these had the fine colored line outside the labels _at the top and bottom_. Owing to the nearness of the stamps on the sheets the perforation generally cut into the stamps, either at the top or bottom, and cut these lines, but the remains will be found on the points left between the holes. Careful search will secure specimens in which both these lines are intact, though they are somewhat rare. The vertical lines, printer's imprint, etc., are of course in the same positions, and the same varieties of finer or coarser lines may be found. The color varies in the same degree. The paper is apparently the same, with the same tinting, from the imperfectly wiped plates.

In later specimens, however, the attempt was made to keep the perforations from impinging on the printed portion. This was done by removing the larger portion of the fine colored lines outside the labels, and with them, portions of the upper and lower ornaments. In many cases, they appear to have been wiped off, and the ends are smudged. In others, they are clear and distinct. A great many varieties result, as a greater or less portion of the lines or ornaments were removed. Some of them are curious enough, in stamps that have always been supposed to present no varieties. The fact being pointed out, it is hardly worth while to attempt to distinguish them.

The vertical lines and printer's imprints are in the same positions. The stamps are still so near together that evenly perforated specimens, i. e.; specimens in which the perforation does not cut some portion of the stamp, are not easily found.

_Two marked varieties_ may be noticed. In one, the outer fine line _is removed above the top label_, while that under the bottom is left intact. In the other, this outer line is removed _below the bottom label_, while it remains intact above the top label. Both these variations are exceedingly uncommon and appear to belong to the bottom and top rows of the sheet respectively, though this has not been verified. The same observations may be repeated as to variations in the thickness of lines, the color of the paper and the impression.
