"Sunday, August 8th. After dinner I went in the small boat to examine an opening on the South shore of the harbour and to look for water of which I found some, on proceeding about a mile and a half up the opening perceived it branched into several different directions. I imagine it runs some considerable distance up into the country. On returning to the vessel I found Captain Flinders with a midshipman and boat's crew on board.* (* "The country round Port Curtis is over-spread with grass and produces the Eucalyptus. Much of the shores and low islands are overspread with Mangroves--the most common being the Rhizophora Mangle of Linn." Flinders.) At daylight Captain Flinders left us desiring me to get under weigh as soon as possible and get round to the Investigator. In working down we sounded constantly and found from 10 to 4 fathoms on each side, a safe channel for any ship and sufficiently broad to work in. "Monday, August 9th. At 3 P.M. got under weigh and made sail out of the harbour tacking occasionally. At 4 P.M. our boat came on board from Faceing Island having found water in small quantities. By 6 P.M. we weathered the south-east point of Faceing Island and stood down towards the Investigator. At 15 past 7 P.M. struck on some sunken reef of rocks about 2 miles from the shore but immediately heaving up all our keels she went over them into deeper water without any damage.* (* See August 22nd. Half of the main keel was afterwards found gone.) At half-past 8 P.M. fired a gun and hoisted a light at the masthead which was answered by the Investigator. By midnight came to with the small bower about 2 cables lengths from the Commodore. At daylight hoisted in our boat, on the Commodore getting under weigh, we did the same. At half-past 9 A.M. passed in between the Rocky Island and Cape Capricorn. At half-past 10 Captain Flinders hailed us and told us to try for a passage in between some rocks and the main of Keppel's Bay. At 50 minutes past 11 A.M. perceived all foul ground ahead in this passage, hauled out and informed the Commodore. At noon bore up for the western part of the Bay, Cape Capricorn bearing east by south distance 10 or 11 miles. "Tuesday, August 10th. At half-past 3 P.M. came to one cable length from the Investigator, lowered our boat and I waited on Captain Flinders. At half-past 4 P.M. Captain Flinders, some of his officers and I went on shore. On ascending one of the highest hills,* (* Named by Flinders Sea Hill.) we perceived the bay to be very extensive with several openings. Here we found a fresh water swamp and saw some ducks and redbills. At sundown Captain Flinders and party returned on board, and Captain Flinders came on board. Weighed and made all sail up the bay. Come to in 3 fathoms a large island in the mouth of the bay North distance 7 or 8 miles. "Wednesday, August 11th. Saw Captain Flinders come out of the entrance he yesterday went into and stand along the south shore of the bay.
