C. 1794. "This sketchbook was named by Finberg on the basis of his erroneous identification of the subject drawn on folio 19 recto (D00284). A watercolour of Marford Mill, Wrexham, Denbighshire (National Museum Wales, Cardiff) was shown at the Royal Academy in 1795. This was based on a sketch made during the Midland tour that Turner undertook in the summer of 1794, Tate D00339 (Turner Bequest XXI L). The contents of the book seem to belong stylistically with the drawings of c.1794, which may have been started before the Midland tour. Finberg observed ‘how much like Dayes’ drawings all the sketches in this book are. Edward Dayes (1763–1804) was a leading topographical watercolourist, who had employed in his studio the young Thomas Girtin (1775–1802), Turner’s friend, colleague and rival throughout the decade. Dayes’s style was a decisive influence on both artists."
