A very slight, in some parts almost imperceptible, sketch, drawn with the sketchbook inverted. A large building with numerous chimneys fields can be seen across fields through a thin screen of trees. This appears to be Cassiobury, from the same angle as in the separate composition study (Tate D08217; Turner Bequest CXX D) and the unfinished painting Cassiobury Park; Reaping (Tate N04663).1 Views of Cassiobury related to this composition also appear in the River sketchbook (Tate D06017, D06042–D06044, D06046, D06048; Turner Bequest XCVI 46, 61a–62, 62a, 63a, 64a).
