In Devon in the summer of 1813,
when the weather was exceptionally
fine, Turner made a series of outdoor sketches. He was encouraged by a local artist, Ambrose Johns, who provided him with the necessary materials: a 'portable painting- box' and sheets of prepared paper. Of the fifteen known today, twelve are in Tate's Collection. Turner is said to have made them very quickly, claiming that one took him less than half an hour. He used thinly diluted oil, over preliminary outlines in chalk. This view of limekilns
at Crabtree was made near the east entrance to Saltram Park.
