Navigation map of the northwest coast of Sumatra. Bathymetry (sea depth), anchor points, shoals and other obstructions (clay, coral, mud, stones, sand) are marked, with hills and settlements to use as landmarks.

The first two sheets of this eight-sheet map focus on British New Guinea, with German and Dutch colonial areas of New Guinea also shown in part. There is a line marking a proposed change in border between Dutch and British territory.
