Voyages of the Dutch brig of war Dourga

The narrative recounts voyages of a brig through little-known islands and coasts in the southern Moluccas and along New Guinea, combining navigational reports and coastal charts with observations on local societies, natural resources, and maritime commerce. It describes landing parties, mapping of islands and reefs, descriptions of fisheries and traded goods such as pearls and trepang, notes on inter-island trade networks and the roles of regional traders, and reflections on previous colonial policies and recent settlements. The account includes practical sailing information, ethnographic descriptions of villages and customs, and an appended chart and practical remarks intended to inform future navigation and government interest.
