What should I do with your strong, manly, spirited sketches, full of variety and glow?öHow could I possibly jointhemontothe littlebit (two inches wide) of ivory on which I work with so fine a brush, as produces little effect after much labour?

-Austen,Jane
  Letter to  J Edward  Austen,16 Dec.

But where dothey find these lines innature? Personally I only see forms that are lit up and forms that are not, planes which advance and planes which recede, relief and depth. My eye never sees outlines or particular features ordetails.I donot count thehairs in the beard of the man who passes byany more than the buttonholes on his jacket attract my notice. My brush should not see better than I do.
