Rare Admiralty chart of the Cayman Islands.

The survey was carried out by George Gauld, a Scottish military surveyor working for the British Admiralty. From 1764 to 1781 he charted the difficult waters off the Gulf Coast of West Florida. Some of his surveys were published by J.F.W. Des Barres in the Atlantic Neptune, but the continuation of his work was hampered during the Revolutionary War due to the activity of American privateers. Gauld was finally captured after the siege of Pensacola in 1781 and paroled to England.

John Walker, founding member of the Royal Geographic Society, was a leading mapmaker and engraver working in London in the first half of the nineteenth century. He is known to have produced numerous charts for James Horsburgh and the Admiralty.
