"I had the honour to be acquainted with that truly British genius at Bath, and have more than once sat by him of an evening and seen him make models - or rather thoughts - for landscape scenery on a little oldfashioned folding oak table, which stood under his kitchen dresser, such an one as I have often seen by the fireplace of a little clean, country ale-house. This table, held sacred for the purpose, he would order to be brought to his parlour, and thereon compose his designs. He would place cork or coal for his foregrounds; make middle grounds of sand and clay, bushes of mosses and lichens, and set up distant woods of broccoli."
