Lands End, Mount's Bay, Cornwall

This coastal survey shows the defence works of Mount's Bay, from Mousehole to Marazion. The area's status as a key defence point is shown by the large scale of the map: 6' to the mile. Positions and weights of cannons around the bay are noted, and the artillery on St Michael's Mount is described by a key. Small crosses mark the positions of rocks in the bay. The irregularly protruding surfaces of Augusta Rock and Long Rock are indicated by intersecting lines of varying lengths, differentiating these from the sand, which is symbolised by dots. The condition of this drawing is excellent. It is coloured with watercolour washes.
