Wilson frequently drew in black chalk on tinted paper. He also made extensive use of stump, a small cylinder of soft chamois leather or paper used for smudging chalk, charcoal or pencil. The mid-tones in Wilson's drawings were created by his use of a pre-prepared paper coated with grey washes. In this work he first applied the chalk quite broadly, later smudging with a stump. Fine black chalk outlines have been added over the stump work to define and strengthen the form. Subtle white highlights added in the sky provide further atmospheric effects.
