Bass would have desired no better recognition than this competent appraisement of his work by one who, when he wrote these paragraphs, had himself experienced a full measure of the perils of the sea. Was Bass at the time of his return aware that he had discovered a strait? It has been asserted that "it is evident that Bass was not fully conscious of the great discovery he had made."* (* F.M. Bladen, Historical Records of New South Wales 3 327 note.) Bass's language, upon which this surmise is founded, was as follows: "Whenever it shall be decided that the opening between this and Van Diemen's Land is a strait, this rapidity of tide...will be accounted for." He also wrote: "There is reason to believe it (i.e., Wilson's Promontory) is the boundary of a large strait." I do not think these passages are to be taken to mean that Bass was at all doubtful about there being a strait. On the contrary, the words "whenever it shall be decided" express his conviction that it would be so decided; but the diarist recognised that the existence of the strait had not yet been proved to demonstration. His reluctance to turn back when he reached Westernport was unquestionably due to the same cause. The voyage in the whaleboat had not proved the strait. It was still possible, though not at all probable, that the head of a deep gulf lay farther westward. The subsequent circumnavigation of Tasmania by Bass and Flinders proved the strait, as did also Grant's voyage through it from the west in the Lady Nelson in 1800.
