During the time we lay in this bay, I took a considerable number of lunar observations, by a mean of which I make Cape Town, in longitude 18 deg. 24' 30" east of the meridian of Greenwich: latitude observed in the bay, 33 deg. 55' south, and variation of the compass, observed about 18 leagues to the westward, 21 deg. 52' west. We had fresh gales from the south-south-east and south-east, and sometimes at south, for the first eight days, which, with a large sea, so very much distressed our cattle, that we were very apprehensive we should lose some of them. On the 25th, being in latitude 38 deg. 40' south, and longitude 25 deg. 05' east, Captain Phillip embarked on board the Supply, in order to proceed singly in that vessel to the coast of New South Wales, where he made sure of arriving a fortnight or three weeks before us, as some of the convoy sailed very heavy; he took with him from the Sirius, Mr. Philip Gidley King, second lieutenant, and Lieutenant Dawes, of the marines, who had hitherto kept an account of the time-keeper, which he also took with him; several carpenters, sawyers, and blacksmiths were likewise put on board the Supply, in order, if they arrived in sufficient time, to examine the place attentively; and the governor had fixed on the most eligible spot to build upon, there to erect some temporary store-houses for the reception of the stores, when the convoy arrived; but as a number of working people would be wanted in carrying on such service, three of the best sailing transports, under the command of Lieutenant Shortland, the agent, were also directed to quit the convoy, and make the best of their way to Botany-Bay; Major Ross, the lieutenant-governor, embarked in one of those transports; the remaining transports and store-ships were left under the care of the Sirius. The next day, after parting company, the Supply was in sight from the mast-head, and the three transports were about seven or eight miles from us, but the wind having shifted to the south-east in the night of the 27th, we stood to the southward and saw no more of them. I was at this time of opinion, that we had hitherto kept in too northerly a parallel to ensure strong and lasting westerly winds, which determined me, as soon as Captain Phillip had left the fleet, to steer to the southward and keep in a higher latitude.
