This drawing covers the boundary between Devon and Somerset. A red pecked line running across the Black Down Hills indicates the border. Dark brushwork interlining ('hachuring') describes relief, making certain place names and details hard to distinguish. Settlements are indicated by red blocks. The draughtsman has drawn individual trees in gardens and orchards. The sandbanks of the River Culm are described by dots. Major communication routes are tinted yellow, following military cartographic practice. Those crossing uncultivated land are drawn with a pecked line.
