About half, or rather more, of the entire number consisted of pencil sketches, in flat oblong pocket-books, dropping to pieces at the back, tearing laterally whenever opened, and every drawing rubbing itself into the one opposite. These first I paged with my own hand; then unbound; and laid every leaf separately in a clean sheet of perfectly smooth writing paper, so that it might receive no farther injury. Then, enclosing the contents and boards of each book (usually ninety-two leaves, more or less drawn on both sides, with two sketches on the boards at the beginning and end) in a separate sealed packet, I returned it to its tin box. The loose sketches needed more trouble. The dust had first to be got off them (from the chalk ones it could only be blown off); then they had to be variously flattened; the torn ones to be laid down, the loveliest guarded, so as to prevent all future friction; and four hundred of the most characteristic framed and glazed, and cabinets constructed for them which would admit of their free use by the public. With two assistants, I was at work all the autumn and winter of 1857, every day, all day long, and often far into the night.

The manual labor would not have hurt me; but the excitement involved in seeing unfolded the whole career of Turner’s mind during his life, joined with much sorrow at the state in which nearly all his most precious work had been left, and with great anxiety, and heavy sense of responsibility besides, were very trying; and I have never in my life felt so much exhausted as when I locked the last box, and gave the keys to Mr. Wornum, in May, 1858. Among the later colored sketches, there was one magnificent series, which appeared to be of some towns along the course of the Rhine on the north of Switzerland. Knowing that these towns were peculiarly liable to be injured by modern railroad works, I thought I might rest myself by hunting down these Turner subjects, and sketching what I could of them, in order to illustrate his compositions.

As I expected, the subjects in question were all on, or near, that east and west reach of the Rhine between Constance and Basle. Most of them are of Rheinfelden, Seckingen, Lauffenbourg, Schaffhausen, and the Swiss Baden.

Having made what notes were possible to me of these subjects in the summer (one or two are used in this volume), I was crossing Lombardy in order to examine some points of the shepherd character in the Vaudois valleys, thinking to get my book finished next spring; when I unexpectedly found some good Paul Veroneses at Turin. There were several questions respecting the real motives of Venetian work that still troubled me not a little, and which I had intended to work out in the Louvre; but seeing that Turin was a good place wherein to keep out of people’s way, I settled there instead, and began with Veronese’s Queen of Sheba;—when, with much consternation, but more delight, I found that I had never got to the roots of the moral power of the Venetians, and that they needed still another and a very stern course of study. There was nothing for it but to give up the book for that year. The winter was spent mainly in trying to get at the mind of Titian; not a light winter’s task; of which the issue, being in many ways very unexpected to me (the reader will find it partly told towards the close of this volume), necessitated my going in the spring to Berlin, to see Titian’s portrait of Lavinia there, and to Dresden to see the Tribute Money, the elder Lavinia, and girl in white, with the flag fan. Another portrait, at Dresden, of a lady in a dress of rose and gold, by me unheard of before, and one of an admiral, at Munich, had like to have kept me in Germany all summer.

Getting home at last, and having put myself to arrange materials of which it was not easy, after so much interruption, to recover the command;—which also were now not reducible to a single volume—two questions occurred in the outset, one in the section on vegetation, respecting the origin of wood; the other in the section on sea, respecting curves of waves; to neither of which, from botanist or mathematicians, any sufficient answer seemed obtainable.

In other respects also the section on the sea was wholly unsatisfactory to me: I knew little of ships, nothing of blue open water. Turner’s pathetic interest in the sea, and his inexhaustible knowledge of shipping, deserved more complete and accurate illustration than was at all possible to me; and the mathematical difficulty lay at the beginning of all demonstration of facts. I determined to do this piece of work well, or not at all, and threw the proposed section out of this volume. If I ever am able to do what I want with it (and this is barely probable), it will be a separate book; which, on other accounts, I do not regret, since many persons might be interested in studies of the shipping of the old Nelson times, and of the sea-waves and sailor character of all times, who would not care to encumber themselves with five volumes of a work on Art.

The vegetation question had, however, at all cost, to be made out as best might be; and again lost me much time. Many of the results of this inquiry, also, can only be given, if ever, in a detached form.

During these various discouragements, the preparation of the Plates could not go on prosperously. Drawing is difficult enough, undertaken in quietness: it is impossible to bring it to any point of fine rightness with half-applied energy.

Many experiments were made in hope of expressing Turner’s peculiar execution and touch by facsimile. They cost time, and strength, and, for the present, have failed; many elaborate drawings, made during the winter of 1858, having been at last thrown aside. Some good may afterwards come of these; but certainly not by reduction to the size of the page of this book, for which, even of smaller subjects, I have not prepared the most interesting, for I do not wish the possession of any effective and valuable engravings from Turner to be contingent on the purchasing a book of mine.[2]

Feebly and faultfully, therefore, yet as well as I can do it under these discouragements, the book is at last done; respecting the general course of which, it will be kind and well if the reader will note these few points that follow.
