A thousand trepang make a picol, of about 125 Dutch pounds; and 100 picols are a cargo for a proa.

It is carried to Timor and sold to the Chinese, who meet them there; and when all the proas are assembled, the fleet returns to Macassar.

By Timor, seemed to be meant Timor-laoet; for when I inquired concerning the English, Dutch, and Portuguese there, Pobasso (the rajah in command) knew nothing of them: he had heard of Coepang, a Dutch settlement, but said it was upon another island.
"There are two kinds of trepang.

The black, called baatoo, is sold to the Chinese for forty dollars the picol; the white, or gray, called koro, is worth no more than twenty.

The baatoo seems to be what we found upon the coral reefs near the Northumberland Islands; and were a colony established in Broad Sound or Shoalwater Bay it might perhaps derive considerable advantage from the trepang.
