THE KEY TO THE INVENTION.

inferior to types made by the type-casting machine. He could make types by a variety of mechanical methods, but they would be imperfect and unsatisfactory. A careful survey of the impracticable inventions in type-founding, recorded in the patent offices of this country and Great Britain, proves that there is, virtually, but one method of making types. The requirements of accuracy and cheapness can be met only by making them of metal, and casting them in a mould of metal.[1]

Although it is clearly understood, by all persons who have a practical knowledge of the subject, that practical types can be made only by casting, many popular books repeat the old story that the first typographic books were printed with types which had been cut by hand out of wood or metal. Whether the mechanics of the middle ages could have done what modern mechanics cannot do,—cut types with bodies of satisfactory accuracy—need not now be considered. The stories about hand-made types—about types that were sawed out of wood blocks—about types that were cut out of wooden rods, and skewered together with iron wires—about types that were engraved on the ends of cubes of metal—will be examined at greater length on an advanced page. Even if these doubtful stories were verified, it would still remain to be proved that the cut types had advantages over letters engraved on wood. It would be difficult to give reasons for their introduction. Books composed with cut types could not be neatly printed; they would be inferior to good manuscripts in appearance, but not inferior in price. Cut types

  1. These observations apply only to the types used for the text letters of books and newspapers. The large types made for the display lines of posters are cut on wood, but these types of wood are used only for printing single lines; they are not combined with the compactness of book types, and do not require their precision of body. The wood types of Japan are, probably, the smallest wood types in practical use; but they are much larger than our book types; they are printed in smaller pages; they are not obliged to stand truly in line, nor to conform to the standards of European and American printers. The cheapness of types which have been cast, as compared with letters which have been engraved, has been explained on page 23 of this work.
