In seven tin boxes in the lower room of the National Gallery I found upwards of nineteen thousand pieces of paper, drawn upon by Turner in one way or another. Many on both sides; some with four, five, or six subjects on each side (the pencil point digging spiritedly through from the foregrounds of the front into the tender pieces of sky on the back); some in chalk, which the touch of the finger would sweep away;[1] others in ink, rotted into holes; others (some splendid colored drawings among them) long eaten away by damp and mildew, and falling into dust at the edges, in capes and bays of fragile decay; others worm-eaten, some mouse-eaten, many torn half-way through; numbers doubled (quadrupled, I should say) up into four, being Turner's favorite mode of packing for travelling; nearly all rudely flattened out from the bundles in which Turner had finally rolled them up and squeezed them into his drawers in Queen Anne Street. Dust of thirty years' accumulation, black, dense, and sooty, lay in the rents of the crushed and crumpled edges of these flattened bundles, looking like a jagged black frame, and producing altogether unexpected effects in brilliant portions of skies, whence an accidental or experimental finger mark of the first bundle-unfolder had swept it away. 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.
