"The Observatory at Greenwich under the direction of an apothecary," says Mr. Whistler, "the College of Physicians with Tennyson as president, and we know what madness is about! But a school of art with an accomplished littérateur at its head disturbs no one, and is actually what the world receives as rational, while Ruskin writes for pupils and Colvin holds forth at Cambridge! Still, quite alone stands Ruskin, whose writing is art and whose art is unworthy his writing. To him and his example do we owe the outrage of proffered assistance from the unscientific--the meddling of the immodest--the intrusion of the garrulous. Art, that for ages has hewn its own history in marble and written its own comments on canvas, shall it suddenly stand still and stammer and wait for wisdom from the passer-by?--for guidance from the hand that holds neither brush nor chisel? Out upon the shallow conceit! What greater sarcasm can Mr. Ruskin pass upon himself than that he preaches to young men what he cannot perform? Why, unsatisfied with his conscious power, should he choose to become the type of incompetency by talking for forty years of what he has never done?" Mr. Whistler winds up by pronouncing Mr. Ruskin, of whose writings he has perused, I suspect, an infinitesimally small number of pages, "the Peter Parley of Painting." This is very far, as I say, from exhausting the question; but it is easy to understand the state of mind of a London artist (to go no further) who skims through the critiques in the local journals. There is no scurrility in saying that these are for the most part almost incredibly weak and unskilled; to turn from one of them to a critical _feuilleton_ in one of the Parisian journals is like passing from a primitive to a very high civilisation. Even, however, if the reviews of pictures were very much better, the protest of the producer as against the critic would still have a considerable validity.
