You think it a great triumph to make the sun draw brown landscapes for you! That was also a discovery, and some day may be useful. But the sun had drawn landscapes before for you, not in brown, but in green, and blue, and all imaginable colours, here in England. Not one of you ever looked at them, then; not one of you cares for the loss of them, now, when you have shut the sun out with smoke, so that he can draw nothing more, except brown blots through a hole in a box.
— John Ruskin
