Items marked 'M' are drawings "by my own Hand" (by Ruskin), P are photographs, E engravings and A by Ruskin's Assistant, Arthur Burgess.
A study by Turner at Scarborough, entirely authoritative as to his methods of work: all of these depending on his determining what he wanted from the beginning. The quantity, as well as the excellence, of what he did, depended entirely on this faculty. He never lost time in hesitation or strength in repentance; though frequently, going over his outline with colour, he would correct his errors with frankness; and you may nearly always know when he has done so, for he is pretty sure in such cases, as in this example, to leave the old outline behind.
Presented by John Ruskin to the Ruskin Drawing School (University of Oxford), 1875; transferred from the Ruskin Drawing School to the Ashmolean Museum, c.1949.

Copy this as well as you can, and observe how the bloom and texture is beginning to come on the distant rocks, by the mere purity of the calmly-laid colour. And put out of your head, finally, any idea of there being tricks or secrets in Turner’s colouring. Flat wash on white paper, of the shape that it should be, and the colour it should be,—that is his secret.
