With the page turned vertically, Turner has used the outer third to record an oncoming storm, apparently accompanied by ‘Thunder’ rather than above a ‘Meadows’ setting as Finberg suggested.1 For other sky and cloud studies, see the entry for the inside of the front cover (D40982). A tall tree is silhouetted to the right, with a low wooded horizon beyond, but the setting in itself is unidentifiable. It may be the Thames Valley, as seen on numerous other pages; see under folio 2 recto (D17775). The stormy view on the verso (D17817) may be at Isleworth.
Finberg 1909, I, p.619.
John Ruskin’s customary red ink page number beside the later stamp is not readily apparent here, although those on other leaves of this sketchbook are generally very faint.
