The figures "201" indicate the _Plate Number_, and "238" the _Current Number_. The _Plate Number_ is also on each of these stamps in microscopic numerals. Corner pair showing _Current Number_ "575" in margin. Corner pair showing _Plate Number_ "15" in margin. The _Plate Number_ is also seen in small figures on each stamp. The above stamps are those of Great Britain _overprinted_ for use in Cyprus.] GENERALISING.--The collecting of all the postage-stamps of the world. GOVERNMENT IMITATION.--Sometimes, when it is desired to reprint an obsolete issue, the original dies or plates are not forthcoming. New dies have, in these circumstances, been officially made, and the resulting labels are euphemistically called "Government imitations." "Forgeries" would be more candid. GRANITE.--_See_ PAPER. GRILLE.--Small plain dots, generally arranged in a small rectangle, but sometimes covering the entire stamp, embossed on certain issues of Peru and the United States. The idea of this was to so break up the fibre of the paper, as to allow the ink of the postmark to penetrate it and render cleaning impossible. GUILLOTINE.--The term used to define a perforating-machine which punches a single straight line of holes at each descent of the needles. GUMPAP.--A fancy term of opprobrium applied to a stamp issued purely for sale to collectors and not to meet a postal requirement. HAIR-LINE.--Originally used to indicate the fine line crossing the outer angles of the corner blocks of some British stamps, inserted to distinguish impressions from certain plates, this term is now often employed to denote any fine line, in white or in colour, and whether intentional or accidental, which may be found on a stamp. HAND-MADE.--_See_ PAPER. HARROW.--The form of perforating-machine which is capable of operating on an entire sheet of stamps at each descent of the needles. And _see_ PERFORATION. HEAD-PLATE.--_See_ KEY-PLATE. IMPERFORATE.--Stamps which have not been PERFORATED or ROULETTED (both of which see) are thus described. IMPRIMATUR.--A word usually found in conjunction with "sheet," when it indicates the first impression from a plate endorsed with an official certificate to that effect, and a direction that the plate be used for printing stamps. IMPRINT.--The name of the printer, whether below each stamp, or only on the margin of the sheet, is called the "imprint." INVERTED.--Simply upside-down. And _see_ REVERSED. IRREGULAR.--_See_ PERFORATION. "JUBILEE" LINE.--Since 1887, the year of Queen Victoria's first Jubilee--whence the name--a line of "printer's rule" has been added round each pane, or plate, of most surface-printed British and British Colonial stamps, in order to protect the edges of the outer rows of CLICHÉS from undue wear and tear. The "rule" shows as a coloured line on the sheets of stamps.
