Early the following morning we sailed out of Port Essington, and passing round its western head, which was named out of respect to my friend Admiral Vashon, we hauled into a bay where a Malay encampment was observed upon the beach, with several proas at anchor close to it; but, as the place offered us no inducement to delay, we steered round the next head, and hauled into another bay, apparently about four miles deep and two broad. The coast here appeared to take a decided turn to the southward, and, as some land was observed on the western horizon, we rightly concluded that we had reached the entrance of the Great Bay of Van Diemen, the examination of which formed a prominent feature in my instructions. The bay was named Popham Bay, and the extremity of the land in sight received the appellation of Cape Don; the former after the late Rear-Admiral Sir Home Popham, K.C.B., and the latter in compliment to Lieutenant-General Sir George Don, K.C.B., the Lieutenant-Governor of the fortress of Gibraltar. The two flat-topped hills, seen from Port Essington, were also observed over the bottom of the bay, and being conspicuous objects, were named Mounts Bedwell and Roe, after the two midshipmen who accompanied me. As we steered into the bay another division of the Malay fleet was perceived at anchor on the eastern shore, close to an encampment: the number of the proas were four; and as we considered ourselves a match for this number, we determined upon remaining the night, and therefore anchored about two miles without them, with our ensign hoisted at the masthead over a large white flag, which was answered by each proa instantly displaying Dutch colours. Soon afterwards a canoe came from the proas, but it required some persuasion to entice them alongside; when they did come, we showed them Sir Stamford Raffles' letter, which they could not read, but on our showing them our rough chart they instantly comprehended our employment, and without further hesitation, two of them came on board. The canoe was fitted for fishing; it was paddled by a man and five boys, and was steered by a younger man, who, from his dress and authority, appeared to be of some consequence amongst them. During their visit their curiosity was much excited by everything they saw; and, having drank pretty freely of our port wine, they talked incessantly. They remained with us three hours, during the greater part of which their canoe was absent catching fish. One of our visitors was very communicative, and by means of signs and a few words of the Malay language, which we understood, he explained that their Rajah's proa was armed with two small guns, and carried a compass. On looking at our binnacle, they pointed to the north-west rhumb, and made us easily understand that it was the course they always steered on their return to Macassar.
