Station on Good's Island, N. 29½° E. Cape Cornwall, N. 68 E. Wallis' Isles, the highest, distant 2½ miles, N. 84 E. Wallis' Isles, a lower and broader, dist. 3 or 4 miles, S. 71° to 64 E. Main land, low sandy point, dist. 8 miles, S. 43 E. Main land, furthest extreme near a smoke, S. 77 E. Between Cape Cornwall and the low main land above set, is the opening called in the old Dutch chart, Speult's River; but which captain Cook, who sailed through it, named Endeavour's Strait. Wallis' Isles are small, low, and rocky, and the northernmost seemed destitute of vegetation; they are surrounded with sandy shoals, which appeared to connect with the main land and leave no ship passage between them. On the north side of the isles there are several banks at the outlet of Endeavour's Strait; and the passage this way into the Indian Ocean is thereby rendered much inferior to that between Wednesday Island and the north-west reef, in which there are no difficulties. [NORTH COAST. GULPH OF CARPENTARIA.] We passed Wallis' Isles, steering southward to get in with the main coast; but the shoals forced us to run seven or eight miles to the west, out of sight of land, before regular soundings could be obtained and a southern course steered into the Gulph of Carpentaria. At dusk, the anchor was dropped in 8 fathoms, soft mud, in latitude 11° 5', as observed from the moon to the north and south, and longitude 141° 51' by time keeper. The variation from amplitude at sunset, was 2° 33', with the ship's head S. S. E., or 3° 10' east when reduced to the meridian; which is 1° 42' less than was obtained from azimuths under Wednesday Island.
