By this day Mr. Bynoe thought I was sufficiently recovered to be able to bear the motion of the ship at sea, and we accordingly sailed in the morning for Swan River. Standing out from Point Pearce we had a better view, than on our first approach, of the coast to the north of it; trending in a North 11 degrees East direction. It had a sandy appearance and was fronted with a rocky ledge at low-water, with one or two remarkable bare sand patches, four or five miles from the Point. We had a shoal cast of nine fathoms (eight at low-water) ten miles west from Point Pearce. In the afternoon we stood to the westward, in very even soundings of 15 fathoms. On the 13th we saw the white cliffs of Cape Rulhieres, which, like Point Pearce, we found to be four miles and a half west of its assigned position. On the 14th and 15th we were beating to the westward with a light and variable wind. SAHUL SHOAL. Our progress was slow, the monsoon being light; we therefore stood to the northward, to find a more steady breeze, and in order, whilst making our westing, to get some soundings over a large dotted space in the chart, bearing the name of the Great Sahul Shoal. We desired also to ascertain the extent of the bank of soundings extending off this part of the Australian continent, which here approaches to within 245 miles of the south end of Timor. The soundings varied, according to the boards we made over it, from 30 to 60 fathoms; the bottom in the lesser depth being a kind of coral, with bits of ironstone mixed with sand; whilst in the greater depth, it was a green sandy mud. On the 17th at 8 P.M., whilst standing on the north-west, near the centre of the eastern part of the supposed Sahul Shoal, the water shoaled suddenly to 16 fathoms, from 68, a mile to the south-east. The helm was put down, and when in stays there were only 14 1/2. The position of this patch is in latitude 11 degrees 8 1/2 minutes South, longitude 126 degrees 33 minutes East. Standing off South by East, in two miles the water deepened to 72 fathoms. It was not until we had gone about ten miles, that we again got into 60 fathoms, on the outer edge of the bank of green sandy mud, fronting the Australian shore, and approaching within a hundred miles of the south end of Timor. This bank appears to be separated from the collection of coral patches, forming the Sahul Shoal by a deep gap or gut, in which the depth generally was above 70 fathoms, with a rocky bottom; though in part of it, in latitude 11 degrees 36 minutes South and longitude 124 degrees 53 minutes East, there was no bottom with 207 fathoms. Dr. Wilson, in his Voyage round the World, mentions that he crossed several parts of the Sahul Shoal on his passage from Timor to Raffles Bay, and never found less than 14 fathoms.
