The next morning we resumed our course along the coast. To the south-west a sandy hillock was observed, which proved to be on Captain Baudin's Peron Island. This was the first opportunity that had occurred by which I could compare my longitude with that of Captain Baudin; and as the Peak of Peron Island is one of his fixed points, and is placed by him in 127 degrees 34 minutes 36 seconds, I find that my chart is in this part 6 minutes 24 seconds to the eastward. In order to set at rest the question of the insularity of this land we passed within it, but not without difficulty, from the numerous shoals that are scattered over the channel. A smoke was seen upon the smaller island among the trees for a few minutes, but no people made their appearance as we passed by. The natives of this part of the coast were seen probably by Tasman; for in Mr. Dalrymple's Papua the following paragraph is found: "In latitude 13 degrees 8 minutes and longitude 146 degrees 18 minutes 6 seconds East (probably 129 1/2 degrees East of Greenwich, and answering to this part) the people are bad and wicked, shooting at the Dutch with arrows without provocation, when they were coming on shore. It is here very populous." On arriving abreast of the peaked hill above-mentioned, a considerable shoal, connected with the mainland, appeared to separate us from it; in crossing it we had three fathoms, and as soon as we passed over it the water deepened instantly to thirteen fathoms. We then bore up and steered through the channel between the islands and the main, which was both narrow and deep towards Channel Point; close to which we had sixteen fathoms, and then hauled up round Peron's South Island. The land from Channel Point trends to the South-South-East, and forms a tolerably deep bight of low, sandy land, terminated by Cliff Head, a high rocky projection well furnished with trees. In this bay there is probably an opening, but it is small and lined with mangroves. After passing Channel Point the depth rapidly decreased, and as we crossed a shoal which runs off from the south-east end of Peron's South Island and extends deeply into the bay, we carried from two and three-quarters to three and a half fathoms. On clearing it we steered South-South-West, and after dark anchored in five fathoms, mud, Cliff Head bearing South 71 degrees East (Magnetic.) The bay between the two projections received the name of Anson Bay, after the noble family of that name. During the night we had a remarkable copious fall of dew. September 3.
