"An Accurate Chart of the Tortugas and Florida Kays or Martyrs Surveyed by George Gauld, A.M. in the Years 1773, 4 &5…", Faden, William

Extremely rare, first edition of this large and detailed chart of the Dry Tortugas and the Florida Keys from the mapping of Scottish surveyor George Gauld. Gauld was assigned by the British Admiralty to chart the waters off of West Florida, where he was taken prisoner by Spanish forces during the Siege of Pensacola in 1781. The chart details the reef and islands, as well as the composition of the ocean floor. The soundings are shown primarily in fathoms with some noted in feet. The perspective views of the islands are arrayed to the lower right and top center of the map. A handsomely engraved anchor decorates the dedication to William Henry, Duke of Clarence, located in the center of the map. This edition is not in any price guide for the last 30 years, and only one much later edition of 1847 can be found offered 17 years ago. Printed on three sheets, now joined together.
