The flood tide having ceased to run, they anchored at noon, and by the sun's meridional altitude, in 27 degrees 27 minutes 16 seconds south latitude. The third island, on which the natives were, bore W 4 degrees S one and a half or two miles distant, and the centres of the two northern ones N 40 degrees and N 15 degrees W. The entrance from Moreton Bay bearing N 68 degrees E from this anchorage, corroborated its latitude by the observation of the 14th, which was taken on the sea side of it although it differed considerably from that given by Captain Cook. This difference may perhaps be thus accounted for. That great navigator finding, by the meridional observation taken on the day following the evening on which he passed this part of the coast, that a northerly current had prevailed in the last twenty-four hours, probably allowed a proportional part of it, to correct the situation of Point Lookout, as given by the log; whereas in reality the northerly current might have commenced only at the time that he opened the Moreton Bay entrance, and became exposed to the outset from it. And it was by no means improbable, that, instead of a northerly, he might have had a southerly set, from the previous noon, when the latitude was 27 degrees 46 minutes to the time when he opened the entrance; in the same manner as it had prevailed the day before; when the observation was 17 minutes south of the log. From the situation of the sloop at this anchorage, Glass-House-Bay seemed to be closed round, except at one small opening which bore S 27 degrees E. To turn up this opening, they got under sail as soon as the ebb tide slacked. On standing near the south part of the shoal that appeared to surround the island to which the natives had retired, one of them came down abreast of the sloop, making the same gestures, and running backwards and forwards, as others had done before; but little attention was paid to him, Mr. Flinders being more intent on getting as far up the bay as possible while the tide favoured him. A little before midnight he was obliged to anchor, finding that the deep water had contracted into a narrow channel.
