gravers understand the laws of their art, as presented by their materials, and on the degree in which such knowledge controls them. The experiments of recent years are to be judged finally by the results; but, in spite of the novel effects obtained, and of the new character that has been given to the art, there is at present no such unanimity, either among the engravers or the public, as to be decisive of the worth of the new work as a whole. While the issue is still doubtful, and the stake is the future of the only art by which those who care for the growth of civilization can develop in the people a sense of art, bring them to an appreciation of its value, open their understandings to its teachings, and fill their lives with its delights, something may be gained by recurring to fundamental principles, as illustrated by the practice of the older masters, not with an end to limit the future by the past, but to foresee it. Such a brief review and summary of past thought respecting the aims and methods of wood-engraving, with such corrections as modern improvements in processes justify, will afford the surest ground for criticism of the work still to be considered.
All the graphic arts have to do with some one or more of the three modes under which nature is revealed to the artist—the mode of pure form, the mode of pure color, the mode of form and color, as they are affected by the different lights and shadows in which they exist. In nature these three modes do not exist separately, and usually no one of them, is so prominent as to efface the others; in the several arts, however, the principal attention is given, now to one, now to another, of them, according to the capacities of the art and the powers of the artists. Thus sculpture deals only with form, and even in painting, which includes all
