To ascertain the precise period and the particular nation of Europe, when and among whom the use of our common paper fabricated from linen rags first originated, was a very earnest object of research with the learned Meerman, author of a now exceedingly rare work on this subject and published in 1767. His mode of inquiry was unique. He proposed a reward of twenty-five golden ducats, to whoever should discover what on due examination should appear to be the most ancient manuscript or public document inscribed on paper manufactured from linen rags. This proposal was distributed through all parts of Europe. His little volume contains the replies which Meerman received. The scholars who remitted the result of their investigations were unable to distinguish between what they estimated as cotton or linen rags. They did, however, establish the fact that paper made of linen rags existed before 1308, and some of them even sought to give the honor of the invention to Germany. They also asserted that the most ancient English specimen of such a paper belonged to the year 1342. The transformation of paper made from every conceivable fibrous material into what is commonly known as "linen" or true paper was of slow growth until after the invention of printing. Following that great event it is surprising, how, in so short a period, the manufacturers of paper improved its quality and the degree of excellence which it later attained. They imitated the old vellum so closely that it was even called vellum and is so known to this day. This class of paper was employed both for writing and printing purposes and has never been excelled, surpassing any like productions of modern times. A curious custom came into vogue during the early infancy of the "linen" paper industry, which is of so much interest and possesses so curious a history as to be well worth mentioning. It is the water mark as it is commonly but erroneously termed in connection with paper manufacture. Its origin dates back to the thirteenth century, though the monuments indicating its use before the time of printing are but few in number. The real employment of the water mark may be said to have commenced at the time when it was a custom of the first printers to omit their names from their works. Also, it is to be considered that at this period comparatively few people could either read or write and therefore pictures, designs or other marks were employed to enable them to distinguish the paper of one manufacturer from another. These marks as they became common naturally gave their names to the different sorts of paper. The earliest known water mark on linen paper represented a picture of a tower and was of the date of 1293. The next known water mark which can be designated is a ram's head and is found in a book of accounts belonging to an official of Bordeaux which was then subject to England. It is dated 1330.
