First publication of this extremely detailed chart of the Java Sea to the China Sea, showing Bangka, the eastern extremity of Sumatra, and the Straits of Bangka and Gaspar. The chart includes extensive depth soundings and copious directions on how to navigate the treacherously narrow seaways of the Lucepara Passage, and Gaspar and Macclesfield Straits between the islands of Sumatra, Banda and Billiton.
“The passage through the Straits of Gaspar to the Northward ought not to be attempted from September to April for strong Southerly Currents and Adverse or Baffling Winds render it very tedious in this Season and even in a Fast Sailing Ship, sometimes impracticable. In all these Straits Piratical Proas usually Lurk, ready to Assault Defenceless Vessels Particularly if they get aground”.
