Drake’s Island is seen from the west on the right, with the profile of Plymouth Citadel to the north-west on the left and the tower of Mount Batten on the east side of Plymouth Sound shown just to the left of the boats. There is a similar view on folio 270 verso (D09466; CXXXI 181a).
With the page turned horizontally, this drawing is part of a sequence working in from the back cover of the sketchbook, which correlates with accounts of a voyage Turner and others made from Plymouth south-east to Burgh Island, returning by land towards Plymouth. The sequence begins on folio 275 (D09476; Turner Bequest CXXXI 186a), under which the overall trip is discussed, and may extend as far as folio 228 verso (Tate D09382; Turner Bequest CXXXI 139a).
Staining to the right matches that on folio 272 recto opposite (D09469; CXXXI 183).
