On the 23rd at 3 P.M. a vessel was seen bearing down before the wind towards the Lady Nelson. The stranger proved to be a Spanish brig carrying prize colours. She had been captured in the River Plate by a privateer which had been fitted out by a merchant at the Cape of Good Hope, and was commanded by Mr. John Black. She was then on her way to the Cape of Good Hope. On coming within hail her master informed the Lady Nelson's commander that he had neither book nor chart on board, and wished to know where he was; he also begged some twine and canvas to repair his sails. The prize was of about 70 tons burthen and was loaded with beeswax, hides, tallow, and tobacco. She was without a boat, as it had been washed overboard, so Lieutenant Grant shortened sail and desired her captain to keep near him and gave him the latitude and longitude. On the following day the Lady Nelson lowered a boat and brought the prize master on board, to whom Lieutenant Grant gave a chart of the Cape and several other necessaries. He asked Mr. Black why he had so boldly approached the Lady Nelson, since his ship was painted like a Spaniard, and so might well have been taken for one. Black's answer was that he knew from her canvas that the Lady Nelson was not an enemy. When he was shown over her he expressed his astonishment at her centre-boards, and her construction was therefore explained to him. But evidently he was not favourably impressed, for when he was being escorted back to his ship he asked one of her sailors if his commander was not mad, for he could not believe that such a small ship as the Lady Nelson could ever accomplish a voyage of discovery. The vessels continued to sail in company towards the Cape of Good Hope. At 5 A.M. on the 7th land was seen from the Lady Nelson, the information being signalled to her companion. Soon after daylight the Lion's Rump was perceived south-east by east 1/2 east, distant five leagues. A little later the ships parted company. Lieutenant Grant had intended to anchor in Simon's Bay, but having discovered that the Lady Nelson had lost both her main and after keels during the voyage, he sailed to Table Bay. On his arrival there Admiral Sir Roger Curtis, who was in command of the station, gave orders for two new keels to be built immediately, and it is recorded that so well did Mr. Boswell, the builder's assistant (the builder himself being absent) perform his task that the new keels reflected the greatest credit on him. On the 16th, her repairs being completed, the Lady Nelson sailed for Simon's Bay and anchored there at 9 A.M. on the following day. Here was found H.M.S. Porpoise, also bound to New South Wales, which left the bay for Sydney in advance of the Lady Nelson. During his stay Lieutenant Grant met a relative, Dr. J. R. Grant, with whom he made several excursions into the interior of the colony.
