I made many inquiries concerning the Malay trepang fishers, whom we had met at the entrance of the Gulph of Carpentaria, and learned the following particulars. The natives of Macassar had been long accustomed to fish for the trepang amongst the islands in the vicinity of Java, and upon a dry shoal lying to the south of Rottee; but about twenty years before, one of their prows was driven by the north-west monsoon to the coast of New Holland, and finding the trepang to be abundant, they afterwards returned; and had continued to fish there since that time. The governor was of opinion, that the Chinese did not meet them at Timor-laoet, but at Macassar itself, where they are accustomed to trade for birds nests, trepang, sharks fins, etc.; and it therefore seems probable that the prows rendezvous only at Timor-laoet, on quitting Carpentaria, and then return in a fleet, with their cargoes. The value of the common trepang at Canton, was said to be forty dollars the picol, and for the best, or black kind, sixty; which agrees with what I had been told in Malay Road, allowing to the Chinese the usual profit of cent. per cent. from Macassar to their own country. About ten days before our arrival, a homeward-bound ship from India had touched at Coepang; and had we been so fortunate as to meet with her, it might have enabled me to put in execution the plan I had formed of sending an officer to England, and returning to the examination of the north and north-west coasts of Terra Australis. This plan was now frustrated; and the sole opportunity of writing to Europe was by captain Johnson, who expected to sail for Batavia in May, and promised to forward our letters from thence. I committed to his care an account of our examinations and discoveries upon the East and North Coasts, for the Admiralty; with the report of the master and carpenter upon the state of the ship, and the information I had obtained of the trepang fishery. Our supplies for the ship, procured at Coepang, were rice, arrack, sugar, and the palm syrup called _gulah_; with fresh meat, fruit, and vegetables during our stay, and for ten days afterwards. The animal food consisted of young _karabow_, a species of buffalo, and of small pigs and kids; the karabow being charged at eight, the pigs at five, and kids at two rix dollars each. Vegetables were dear and not good, and for many of the fruits we were too early in the season; but cocoa-nuts, oranges, limes, bananas, and shaddocks were tolerably plentiful. Tea, sugar candy, and some other articles for our messes, were purchased at the little shops kept by the Chinese-Malays; and poultry was obtained along-side by barter.
