We returned to the tent at sunset; and there passed a disagreeable night amongst musketoes, sand flies, and ants. At four in the morning [THURSDAY 16 SEPTEMBER 1802] the ebb had made, and we embarked in the boat; but the depth of water was so little that we could not proceed, and were obliged to re-land and wait for the following tide; not without apprehension of being left till the next springs came on. At two in the afternoon the flood came up rapidly, and in half an hour it was high water; we set off immediately, and after some trouble from the shoals, reached the brig at five o'clock. Mr. Murray got under way at three the next morning [FRIDAY 17 SEPTEMBER 1802] to beat down to Upper Head, the wind being from the northward; but the Lady Nelson getting aground, I went off with Mr. Brown in my boat, and reached the ship at seven o'clock, and in the evening, the brig arrived. Lieutenant Fowler had gone through the most essential duties, and the ship was nearly ready for sea; but on landing at the tents I found that the time keepers had been let down, and the business of finding new rates for them was to be recommenced. This accident would require a week to be repaired; and being unwilling to remain so long inactive, I determined to leave Mr. Flinders at Upper Head, and take the ship over to the inner end of Thirsty Sound, where it appeared there was something to correct in captain Cook's chart. SATURDAY 18 SEPTEMBER 1802 The Lady Nelson had lost two sheets of copper, and the trunks of the sliding keels required some reparation; I therefore desired lieutenant Murray to lay his vessel on shore and get these matters arranged, to cut wood for himself, and be ready to sail in a week for Torres' Strait; and his stock of water was completed out of the Investigator. SUNDAY 19 SEPTEMBER 1802 On the 19th in the morning we unmoored the ship, and a little before low tide stretched over towards Thirsty Sound; but the numerous shoals to be encountered, and which cannot be concisely described otherwise than in a chart, caused much delay; and it was near noon of the day following [MONDAY 20 SEPTEMBER 1802] before we anchored at the south end of Long Island, in 3 fathoms, and about one mile from the low mangrove shore. At the south end of the island was a small hill, bearing S. 55° E. one mile and a half from the ship, where I landed with a party of the gentlemen; it forms the west point of the inner entrance to Thirsty Sound, as some low red cliffs, one mile and a half distant, do the east point; but a shoal, dry at low water, lies in the middle, and the channels on each side are not calculated for a ship. The small hill was found to be on a detached islet one mile long, the greater part of which is mud covered with mangroves; the hill is partly excavated by an arched way running through it, and the stone is of a mixed red and white colour, and of an ochry consistence. From the highest top, I set:
