The collection consists of three maps: 1) Hacke's “Draft of the Golden & adjacent islands with part of ye Isthmus of Darien as it was taken by Captain Ienefer where ye Scots West-India Company setteled” plus Hacke & Morden's “New Map of Ye Isthmus of Darien in America”; 2) “A Map of Part of the Isthmus of Darien, shewing the communication with Panama, from Portobello & Chagre both by land, and by water”; 3) “Rade du Darien et les Isles Voisines”. Maps 1 and 3 relate to the Darién scheme, an attempt by Scotland to establish a colony called 'New Caledonia' on the Isthmus of Panama at the end of the 17th century (1698-1699). It was poorly managed and many colonists succumbed to disease. It was abandoned after a siege by Spanish forces in April 1700.
