After completing our survey at Letti we worked to the eastward, against the monsoon, keeping as close as possible under the lee of the Serwatty group, which enabled us to make a rough survey of the islands composing it. These proved to be very incorrectly laid down in the only chart we had, and from what we saw they require a far more detailed examination than we had time to devote to them; this would, I have no doubt, lead to the discovery of many anchoring-places, where vessels might carry on trade with the natives, with much greater ease and safety than they can do when obliged to stand off and on with the vessel while the boats are sent in to trade; since, by these means, the crew are necessarily divided, are liable to fall an easy prey to the natives, should the latter be inclined to treachery. The various traders we met with, during this, as well as on our former visit to the islands, all agreed in warning us against the inhabitants of Timor Laut and Baba, as people not at all to be trusted. It is much to be hoped that if Port Essington should ever become a place of much trade, that these people will be more civilized, as from the easy communication, in either monsoon, Timor Laut will be much frequented by the settlers at Port Essington, in order to procure the tropical productions abounding there, which they would not find on the Australian coasts. The Arrou islands, for the same reason, will hold out great inducements to traders, as the timber found there is infinitely superior, for most purposes, to any found on the Cobourg peninsula. RETURN TO PORT ESSINGTON. As our provisions were running short, and the time had arrived when we were expected to return to the settlement, I had not time to stop to examine several places I wished to see, particularly the southern part of the island of Timor Laut, where from information we received at Banda, a very large and secure harbour is said to exist, available in both monsoons. The island of Serra was another point, as it is stated to be a very good place for obtaining supplies. In crossing over to Australia we saw Timor Laut, off which we experienced a very fresh South-East breeze and a heavy sea, which continuing to prevail with a strong current setting to leeward, we were in consequence eight days reaching Port Essington, where we found that all had gone on well during our absence.
