of all real art. I defy any man to cut cleaner strokes than I do, or rougher, when I please; and assert, that he who thinks he can engrave or paint either, without being a master of drawing, is a fool. Painting is drawing on canvas, and engraving is drawing on copper, and nothing else. Drawing is execution and nothing else; and he who draws best must be the best artist. And to this I subscribe my name as a public duty.
