Ruskin makes unsustainable comments in this passage, particularly that Constable was 'unable to draw' (see Ruskin's criticism of Constable). For recent assessments of the development and quality of Constable's drawings, see: Fleming- Williams, Constable:Landscape Watercolours & Drawings, 1976, Fleming-Williams, Constable and his Drawings, 1990, and Leggat, Constable a Master Draughtsman, 1994.
