This establishment had been put up by the crew of a small vessel from Sydney, and several such have at various times made voyages along this coast and in Torres Strait, collecting trepang and tortoiseshell, the latter procured from the natives by barter.

The method of curing the trepang is thus described by Captain Flinders: "They get the trepang by diving, in from three to eight fathoms water; and where it is abundant, a man will bring up eight or ten at a time.

It is formed principally of coral, on the surface of which we found the gray trepang; a small Chama gigas, a cypraea, a pretty azure-coloured species of asteria, and a few bivalve shells.

I want to know what a coral reef really looks like, and if you saw any trepangs upon them?
