It is possible for one to be a good Painter, and yet not to be able to draw well with the pen, because there is not required in a Painter such a curious and exact carriage of the hand : but it is impossible for one ever to Grave or Etch well, except he can draw well with the pen. First therefore presupposing you can doe the first before you attempt the second, you must provide divers graving tooles, both long and short : some for hard worke, some for sweet worke, some for smaller worke, and some for greater: also a peece of a Beaver hat, and a good oyle stone, smoothed on one side, and free from pin holes, and plates of Copper or Brasse exactly polished.
