This drawing is part of a set of tree studies by Wilson in the Oppé Collection. Black chalk was a medium favoured by Wilson. Here the textured surface of the laid paper has been heightened by the chalk. He has used light pressure to depict the undulations of the trunk, whilst tone has been suggested by the application of darker vertical strokes in the centre of the trunk. In contrast to other drawings by Wilson exhibited here, he has used the chalk like a pencil , primarily to draw lines, rather than smudging the chalk to suggest tones.
