Governor King, in addition to ordering Grant to return and survey the deep bay which he had passed in Bass Strait between Cape Sir William Grant and Wilson's Promontory, instructed him to ascertain the correct latitude of the promontory and of the islands lying off it. He was also told to survey King Island, then to sail to King George's Sound and, in returning to Wilson's Promontory, to make a general survey of the whole of the south coast, going to the head of every inlet as far as possible. Dr. Bass, when discovering Bass Strait, had rounded the promontory and entered a harbour which, as Grant has told us, he named from its relative situation--Western Port. In his journal Grant says that it was reserved for the Lady Nelson to ascertain accurately the extent of Bass Strait, but he did not carry out the whole of King's instructions on this second voyage although his examinations of Jervis Bay and of Western Port proved of great value and added much to the knowledge of both harbours. Besides Ensign Barrallier, Mr. Caley, botanist, four soldiers of the New South Wales Corps and two natives (Euranabie and his wife Worogan) went with the expedition, and Mr. John Murray joined the ship as first mate* (* Formerly Master's Mate on board H.M.S. Porpoise.). The Bee, of 15 tons, formerly a ship's launch, was also fitted out to accompany her. The two ships left Port Jackson on March 8th, Lieutenant Grant particularly wishing to make the examination of Jervis Bay* (* Jervis Bay, named in honour of John Jervis, Lord St. Vincent, was discovered by Lieutenant Richard Bowen in 1791.) on his way southwards in order "to secure a harbour" if obliged to run out of Bass Strait. The Bee, however, did not stay long with the Lady Nelson. On the morning of the 9th the Master hove to and informed Grant that he had shipped much water and that the sea was too heavy for him. Before sending the vessel back to Port Jackson Grant wrote a letter to the Governor at Sydney stating the reason of her return. He placed the letter between two flat pieces of lead, and running close to the Bee threw it on board. The Lady Nelson then continued her voyage, and at 4 P.M. on the 10th sighted the north head of Jervis Bay bearing west-south-west 8 or 9 miles distant. At seven o'clock on the following morning the first mate was sent in the boat to look for an anchorage, and returned at nine with one of the natives, bringing the information that there was good holding ground in the southernmost cove between an island and the main. At half-past ten the Lady Nelson anchored in this cove in four fathoms water, fine sandy bottom, having run over a shallow some four cables' length which was easily distinguished by the colour of the water. The native who came on board was a middle-aged man, stout and muscular, who showed no symptoms of fear. It was evident that he had seen white men before and he often repeated the words "blanket" and "woman."
