As my attention has been more readily directed to matters connected with my own profession than any other, it is not surprising that I should find almost a total absence of practical knowledge in all English authors who have written the early history of wood engraving. From the first occasion on which my attention was directed to the subject, to the present time, I have had frequent occasion to regret, that the early history and practice of the art were not to be found in any book in the English language. In the most expensive works of this description the process itself is not even correctly described, so that the reader--supposing him to be unacquainted with the subject--is obliged to follow the author in comparative darkness. It has not been without reason I have come to the conclusion, that, if the _practice_, as well as the _history_ of wood engraving, were _better understood_, we should not have so many speculative opinions put forth by almost all writers on the subject, taking on trust what has been previously written, without giving themselves the trouble to examine and form an opinion of their own. Both with a view to amuse and improve myself as a wood engraver, I had long been in the habit of studying such productions of the old masters as came within my reach, and could not help noting the simple mistakes that many authors made in consequence of their knowing nothing of the practice. The farther I prosecuted the inquiry, the more interesting it became; every additional piece of information strengthening my first opinion, that, “if the _practice_, as well as the _history_ of wood engraving, were _better understood_,” we should not have so many erroneous statements respecting both the history and capabilities of the art. At length, I determined upon engraving at my leisure hours a fac-simile of anything I thought worth preserving. For some time I continued to pursue this course, reading such English authors as have written on the origin and early history of wood engraving, and making memoranda, without proposing to myself any particular plan. It was not until I had proceeded thus far that I stopped to consider whether the information I had gleaned could not be applied to some specific purpose. My plan, at this time, was to give a short introductory history to precede the practice of the art, which I proposed should form the principal feature in the Work. At this period, I was fortunate in procuring the able assistance of Mr. W. A. Chatto, with whom I have examined every work that called for the exercise of practical knowledge. This naturally anticipated much that had been reserved for the practice, and has, in some degree, extended the historical portion beyond what I had originally contemplated; although, I trust, the reader will have no occasion to regret such a deviation from the original plan, or that it has not been _written_ by myself. The number and variety of the subjects it has been found necessary to
