adequately in the terms of some other art, but which he chose on this occasion to express in pictorial terms. In this way we can understand why Turner did, as a matter of fact, frequently and constantly attempt to express his ideas in the form of verbal poetry, and why, in the drawing we are now considering, he felt himself justified not only in filling out his sketch with details that were neither there nor in the real scene, but also in taking considerable liberties with the facts contained in the sketch, altering them and falsifying them in ways that could not be defended if his aim had been to reproduce the actual scene itself. The colouring too of Mr. Walter’s drawing owes much more to Turner’s study of Wilson’s pictures than to his visual memory of natural scenes; that is to say, the colour is used as an instrument of expression,--as a means to bring the imagination and feelings of the spectator into harmony with the artist’s ideas, as well as to indicate in the clearest possible manner that it was not the artist’s intention to represent the actual scene in its prosaic details. This picture, with the others exhibited in 1798, settled the question for Turner’s brother artists and for himself that he was a genuinely imaginative artist and not a merely clever topographical draughtsman. The following year he was elected an Associate of the Royal Academy, at the early age of twenty-four, and throughout his long life he always regarded himself as entitled to take any liberties with actual topographical facts that the expression of his ideas demanded. The success of the first _Norham Castle_ drawing induced Turner to repeat the subject several times. The late Mrs. Thwaites had another water-colour of it in her collection, there are at least three unfinished versions in the National Gallery, and I have seen a version of it in oil. The subject was engraved in the “Liber” from what purported to be the picture in the possession of the Hon. Mr. Lascelles, but really from a fresh design made by the artist. Then Turner painted the subject again for Mr. Fawkes of Farnley, and again, about 1822 or 1823, he made the drawing for the “Rivers of England” series, here reproduced. What is so interesting in all this is that the details in each of these versions are different, yet they all seem to have been based on the same pencil sketch. The relative size of the castle varies in each drawing, as well as the details of its embrasures and crumbling masonry; the character of the river banks also varies. In the earlier versions the right bank is steep and rocky, as suiting the solemn and gloomy effect of the subject; in the latest version, where the humble pastoral life of the present is thrown more into prominence, this bank becomes flat and peopled with fishermen, their boats and cows.
