of the coast was being approached. "The tide from the north-eastward, apparently the ebb, ran more than one mile an hour, which was the more remarkable from no set of the tide worthy to be noticed having hitherto been observed upon this coast." The ship had rounded Cape Catastrophe, and the land led away to the north, whereas hitherto it had trended east and south. What did this mean? Flinders must have been strongly reminded of his experience in the Norfolk in Bass Strait, when the rush of the tide from the south showed that the north-west corner of Van Diemen's Land had been turned, and that the demonstration of the Strait's existence was complete. There were many speculations as to what the signs indicated. "Large rivers, deep inlets, inland seas and passages into the Gulf of Carpentaria, were terms frequently used in our conversations of this evening, and the prospect of making an interesting discovery seemed to have infused new life and vigour into every man in the ship." The expedition was, in fact, in the bell-mouth of Spencer's Gulf, and the next few days were to show whether the old surmise was true—that Terra Australis was cloven in twain by a strait from the Gulf of Carpentaria to the southern ocean. It was, indeed, a crisis-time of the discovery voyage.
But before the gulf was examined, a tragedy threw the ship into mourning. On the evening of Sunday, February 21st, the cutter was returning from the mainland, where a party had been searching for water in charge of the Master, John Thistle. She carried a midshipman, William Taylor, and six sailors. Nobody on the ship witnessed the accident that happened; but the cutter had been seen coming across the water, and as she did not arrive when darkness set in, the fear that she had gone down oppressed everybody on board. A search was made, but ineffectually; and next day the boat was found floating bottom uppermost, stove in, and
