This attractive bird's-eye plan shows the town of Calliaqua (Cariacoua) at the southern end of St. Vincent. Two "proposed forts" are depicted, as well as soundings, shoals, and a location suitable for anchoring both small and large vessels. The tiny island just south of Young Island, here called Le Grand Islet, later became the location for Fort Duvernette.
