until the eighth century. [Footnote 23: The terms library and folio are derived from _liber_, the _inner bark_; and _folium_, a leaf.] Cotton paper was introduced into Europe from China about the ninth century, and superseded parchment. Documents in cotton, of that period, including diplomas of Italian princes, have been preserved in foreign museums. The first manufactory of cotton paper was established in Spain in the twelfth century, also almost contemporaneously in France and Germany; but, its durability being questioned, all state and official documents for preservation were written, or at least engrossed, on parchment or vellum. Paper made from linen rags is supposed to have originated in Spain, and to have been introduced into England in the fourteenth century. It has been considered a pre-eminently good material, with which none of the various substances used from the earliest times to the present can victoriously compete. Dr. Fuller, a noted and quaint writer of the seventeenth century, affected to detect national characteristics from the qualities of the paper produced in the respective countries; e.g., Venetian paper he compared to a courtier of Venice--elegant in style, light, and delicate. French paper corresponds with the light-heartedness and delicacy of the Frenchman. Dutch paper, thick and coarse, sucking up ink like a sponge, is in this respect, he says, a perfect image of the Dutch race, which tries to absorb everything it touches. Durability distinguished English paper, a quality essentially English. In 1749 the Irish Parliment granted a sum of money to a Mr. Jay, for having introduced the first paper factory into Ireland, which probably had the distinction of anticipating England in this respect. Be this as it may, the first eminent establishment of the kind was not in operation in England until 1770, when a paper-mill was erected at Maidstone, by John Whatman, who had acquired much knowledge in the art by working at Continental factories. In the British Museum is a book, dated 1772, which contains more than sixty specimens of paper, made of different substances. The paper called foolscap, so common in our use, derives its appellation from the historical circumstances following: When Charles I. of England found difficulties in raising revenue, he granted monopolies, among which was one for making paper, the water-mark of which was the royal arms. When Cromwell succeeded to power, he substituted, with cruel mockery, a fool's cap and bells for the royal arms. Though this mark was removed at the Restoration, all paper of the size of the "Parliamentary Journal" still bears the name of foolscap.
