Numbered by Finberg as folio 10 of this book, this has since been rebound as folio 12. Turner’s sketch exploits the particularly strong preparatory tinting of the paper, the disc and glow of the sun being vigorously scratched out. Notwithstanding Finberg, the subject is presumably sunset, as later painted by Turner from a similar viewpoint in Calais Sands, Low Water, Poissards Collecting Bait, shown at the Royal Academy in 1830 (Bury Art Gallery and Museum).1
