The scene was in every way delightful; he stood there, a miniature Mephistopheles, mocking the majority! He was like a brilliant surgeon lecturing to a class composed of subjects destined ultimately for dissection, and solemnly assuring them how valuable to science their maladies were, and how absolutely uninteresting the slightest symptoms of health on their part would be. In fairness to the audience, however, I must say that they seemed extremely gratified at being rid of the dreadful responsibility of admiring anything, and nothing could have exceeded their enthusiasm when they were told by Mr. Whistler that no matter how vulgar their dresses were, or how hideous their surroundings at home, still it was possible that a great painter, if there was such a thing, could, by contemplating them in the twilight and half closing his eyes, see them under really picturesque conditions, and produce a picture which they were not to attempt to understand, much less dare to enjoy. Then there were some arrows, barbed and brilliant, shot off, with all the speed and splendour of fireworks, and the archaeologists, who spend their lives in verifying the birthplaces of nobodies, and estimate the value of a work of art by its date or its decay; at the art critics who always treat a picture as if it were a novel, and try and find out the plot; at dilettanti in general and amateurs in particular; and (O mea culpa!) at dress reformers most of all. 'Did not Velasquez paint crinolines? What more do you want?' Having thus made a holocaust of humanity, Mr. Whistler turned to nature, and in a few moments convicted her of the Crystal Palace, Bank holidays, and a general overcrowding of detail, both in omnibuses and in landscapes, and then, in a passage of singular beauty, not unlike one that occurs in Corot's letters, spoke of the artistic value of dim dawns and dusks, when the mean facts of life are lost in exquisite and evanescent effects, when common things are touched with mystery and transfigured with beauty, when the warehouses become as palaces and the tall chimneys of the factory seem like campaniles in the silver air.
