History has not given us the names of ancient ink makers; but we can believe there must have been during a period of thousands of years a great many, and that the kinds and varieties of inks were without number. Those inks which remain to us are to be found only as written with on ancient MSS.; they are of but few kinds, and in composition and appearance preserve a phenomenal identity, though belonging to countries and epochs widely separated. This identity leads to the further conclusion that ink making must have been an industry at certain periods, overlooked by careful compounders who distributed their wares over a vast territory. "Gall" ink and "linen" paper as already stated are Asiatic inventions. Both of them seem to have entered Europe by way of Arabia, "hand in hand" at the very end of the eleventh or beginning of the twelfth centuries and for the next two hundred years, notwithstanding the fact that chemistry was almost an unknown science and the secrets of the alchemists known only to the few, this combination gradually came into general vogue. In the fourteenth century we find one or both of them more or less substituted for "Indian" ink, parchment, vellum and "cotton" paper. It was, however, the monks and scribes who manufactured for their own and assistants' use "gall" ink, just as they had been in the habit of preparing "Indian" ink when required, which so far as known was not always a commodity. As an industry it can be said to have definitely begun when the French government recognized the necessity for one, A. D. 1625, by giving a contract for "a great quantity of 'gall ink' to Guyot," who for this reason seems to occupy the unique position of the father of the modern ink industry. Ink manufacture as a growing industry heretofore and to a large extent at present, occupies a peculiarly anomalous situation. Other industries follow the law of evolution which may perhaps bear criticism; but the ink industry follows none, nor does it even pretend to possess any. Thousands are engaged in its pursuit, few of whom understand either ink chemistry or ink phenomena. The consumer knows still less, and with blind confidence placidly accepts nondescript compounds labeled "Ink," whether purchased at depots or from "combined" itinerant manufacturing peddlers and with them write or sign documents which some day may disturb millions of property. And yet in a comparative sense it has outpaced all other industries. With the commencement of the eighteenth century we find the industry settling in Dresden, Chemnitz, Amsterdam, Berlin, Elberfield and Cologne. Still later in London, Vienna, Paris, Edinburgh and Dublin, and in the first half of the nineteenth century in the United States, it had begun to make considerable progress.
