On recurring back to the last altitudes taken for the time-keeper before our making Van Diemen's Land, and carrying it on by the log, we found that the error on making that land was but a very few miles of longitude, and that error most probably was in the carrying on the log; so that there was every reason to think, that the violent agitation of the ship during that time, was the cause of that change in the watch, and which I own I was not at all surprised at, but think it highly probable, as the watch lay in a box upon soft cushions, and that box screwed down to a place securely and firmly fixed for that purpose: I cannot help thinking but that so very valuable a piece of watch-work (for I do really think, from the experience I have had of it, that a superior piece of work was never made) would be better fixed upon a small horizontal table, made on purpose, and well secured; and under the box which contains the watch, a kind of spiral spring or worm, which, with every jerk or pitch of the ship, would yield a little with the weight of the watch, and thereby take off much of that shock which must in some degree affect its going. The winds now (rather unfortunately for us), after 24 hours calm, inclined again to the southward, and we kept plying to windward with all the sail we could carry. Right off Cape Three Points, at six leagues distance from the shore, we sounded in 75 fathoms, over a bottom of fine grey sand. On the 8th, a light air from the northward in the night, carried us by day-light in sight of the entrance of Port Jackson; and in the evening of the 9th, we entered between the heads of the harbour, and worked up to Sydney Cove, where we anchored before dark, after an absence of 219 days, 51 of which we lay in Table-Bay, Cape of Good Hope: so that, although during this voyage we had fairly gone round the world, we had only been 168 days in describing that circle; and, by taking a mean of the highest and lowest latitudes we sailed in, we shall find our track nearly in latitude 45 deg. south. We found in the cove the Supply armed tender. Our passage, since we came round Van Diemen's Land, had been attended with much bad weather, very violent squalls, and a thick haze; particularly with the wind from the eastward: I had before observed, that in the winter-time, upon this coast, we were subject to much bad weather; and this passage convinced me of the necessity, when ships are intended to be sent to this settlement, that the season should be considered and attended to. During the summer months we were sometimes subject to thunder, lightning, and strong squalls; but in general the weather is fine. If in the fairest weather you observe it to lighten in the lee part of the horizon, you should prepare for a squall from that quarter, which is in general pretty severe.
