introduced in Europe, of the German card-makers, to use stencils in order to draw, accurately and invariably, the outlines of the figures on their cards, which were then filled in with color by the hand. This, though not originally intended to facilitate multiplication so much as accuracy, would naturally suggest that idea.

The next known step, in progress, was the use of monogrammatic stamps, some of them of most elaborate and exquisite design and execution, for the impression on illuminated manuscripts, such as missals, breviaries, bibles and other religious works, of the large, beautiful and often many-colored initial letters.

And these, there is much reason to believe, were more or less in use so early as A. D. 1400.

The history of the first known wood-cut is as follows. From a convent within fifty miles of Augsburgh, where in 1418 the first mention of a kartenmacher, card-engraver, occurs, the earliest wood-cut known—the St. Christopher, now in the collection of the Earl of Spencer—was obtained. The outlines are engraved on wood, and thence taken off in dark coloring matter, resembling printer’s ink, on the paper; after which the impression appears to have been colored by means of a stencil.

This cut is extremely well-designed, as regards the principal figures, which, with the exception of the extremities, are executed in such style as would not disgrace Albert Durer himself. The perspective is—as usual, in old wood-cuts even of a later date than this, and executed by artists of high grade, such as Hans Burgmair and Hans Schaufflein, nearly a century afterward—utterly disregarded. It was, indeed, scarce understood.

The second and third cuts in existence, also in Lord Spencer’s collection, are an “Annunciation” and “St. Bridget,” both similarly printed in outline, and colored by stenciling, the last of these is curious, as showing, on examination of the back of the plate—for it is not, like the others, pasted into a book—that the impression was not taken by means of a press, but by friction on the paper superimposed to the block, by means of a burnisher or similar instrument, just as proofs are now taken by engravers.

From this period, the succession and progress of the art is clearly to be traced. First, through figure blocks, with letterings sculptured on them in relief, to solid blocks carved in wood and printing off entire pages, as is done by modern stereotypes, with or without pictures attached. At this stage of the work the idea of reproduction and multiplication had obtained as the primary objects of the art.

The next step was the invention of movable types capable of being combined at will into words and sentences, braced into the form of pages, and, the work completed, distributed, and combined anew for the composition of other and different works. From this period, wood-engraving proper, and type-cutting in wood, became separate arts; and ere long—metallic types engraved at first, and afterward cast, replacing the wooden letters—the latter passed into oblivion, while the former has increased gradually and steadily, though with occasional pauses and interruptions, until the present day; when it has attained its highest known perfection, while it is still so far progressive, that it is not easy to predict what may be expected of its future improvement and excellence.

And here it may be well, since few persons comparatively speaking, even of those who are admirers and more or less judges of the art, have a distinct idea of its precise character and nature, to explain briefly in what it consists and wherein it differs from engraving on copper or steel.

All engraving consists of cutting with a sharp instrument into a hard surface, whether of wood or metal, so that when the picture is perfected on the wood or metal, ink may be applied to the surface, from which fac-similies may be taken off by the impression of moistened paper on the block or plate by means either of friction or pressure.

The practice thus far is identical whether steel, copper or wood is to be the material engraved.

But with this all similarity ends.

In steel or copperplate-engravings the ink, when applied, is received into the engraved lines, and is wiped off from the prominent portions; so that, in the impressions taken on paper, the lines cut into the plate communicate the shades, the portions left in relief on the plate remain colorless and blank.

In wood-engravings, on the contrary, the ink, when applied, is taken up by the parts left prominent, and never penetrates into the engraved lines; so that, in the impressions taken on paper, the portions of the wood less prominent communicate the shades, the portions cut away, on the block, remain colorless and blank.

Thus the same process, pursued on the metallic plate, and on the wood-block, produces effects diametrically opposite, and to produce the same effects from the two materials converse processes must be pursued.

Thus we will engrave the word

on a plate of metal, and on a block of wood, and let these two engravings be perfect fac-similies, line for line alike, in form, length, width and depth; then, the impression taken from the engraved plate of metal, being derived from the depressed lines, filled with ink, into which the paper is forced by the action of the press, will present the appearance shown above.

But, the impression taken from the engraved block of wood, being derived from the elevated portions of the block, covered with ink, upon which the paper is impinged by the action of the press, will give the appearance presented below.

Observe, therefore, that as on the two engravings, the same work produces results exactly the reverse, one of the other; so to produce the same effect from each of the two engravings, we must have recourse to two different processes.

The former of the above two cuts, is the effect produced on paper from a metallic plate, into the surface of which the lines producing the shades are engraved or cut in.

The same effects precisely may be produced on paper from a wood-block; but, in order to produce it, all the portions of the wood-block, which now give solid black upon the paper, must be cut out of the wood; leaving the lines, which now give white on the paper, prominent, so as to receive the ink and make their impression on the surface to be printed.

The same end could be attained on the other side—that is to say, a light lettering on a dark ground—by cutting away all the metal, except the lines now producing dark impressions on a light ground, which would then give light lines on a dark ground; but the labor of doing this would be interminable, and the advantage gained, nothing.

This principle once understood, the whole system becomes comprehensible at a glance. If, in an engraving on metal, all the lines cut into the plate were of equal depth and capacity, all the impressions would be equal as to shade, and the print would display an impression in pure black and pure white only, without intermediate tints.

So, in cutting a wood block, if all the prominent parts be left equally prominent, the quantity of ink deposited by each and all will be identical, and
