This drawing demonstrates the extremely fine line-work which can be achieved with red chalk. The thinness of the lines suggests that Dalton used a natural red chalk, since these tended to be harder than fabricated or synthetic red chalks. Dalton would probably have fastened a stick of red chalk into a holder and kept the point sharp with a knife. The darkest areas within the figure have been made by cross-hatching and drawing closely spaced narrow lines one on top of the other.
