We remained at the anchorage the following day in order to obtain some lunar distances; and in the evening Mr. Bedwell sounded across the bay towards the south end of Magnetical Island, and also the channel between that island and the main. The soundings therefore laid down are from his report, from which it appears that there is a good and clear passage through, and excellent anchorage upon a muddy bottom all over the bay. No natives were seen during our visit, but the remains of nine huts were counted in different parts of the bay, near the edge of the beach. The inhabitants were not however far off, for the tracks of human feet as well as those of a dog were noticed very recently imprinted on the gravelly bed of the fresh-water stream; and we were probably watched by them in all our proceedings. Near the extremity of the Cape some bamboo was picked up, and also a fresh green coconut that appeared to have been lately tapped for the milk. Heaps of pumice-stone were also noticed upon the beach; not any of this production, however, had been met with floating. Hitherto, no coconut trees have been found on this continent; although so great a portion of it is within the tropic and its north-east coast so near to islands on which this fruit is abundant. Captain Cook imagined that the husk of one, which his second Lieutenant, Mr. Gore, picked up at Endeavour River, and which was covered with barnacles, came from the Terra del Espiritu Santo of Quiros;* but, from the prevailing winds, it would appear more likely to have been drifted from New Caledonia, which island at that time was unknown to him; the fresh appearance of the coconut seen by us renders, however, even this conclusion doubtful; Captain Flinders also found one as far to the south as Shoal-water Bay.** (*Footnote. Hawkesworth volume 3 page 164.) (**Footnote. Flinders volume 2 page 49.) Several kangaroos were started by our wooding party but none were taken. In the gullies Mr. Cunningham reaped an excellent harvest, both of seeds and plants. Here as well as at every other place that we had landed upon within the tropic, the air is crowded with a species of butterfly, a great many of which were taken. It is doubtless the same species as that which Captain Cook remarks as so plentiful in Thirsty Sound; he says, "we found also an incredible number of butterflies, so that for the space of three or four acres, the air was so crowded with them, that millions were to be seen in every direction, at the same time, that every branch and twig were covered with others that were not upon the wing."* The numbers seen by us were indeed incredible; the stem of every grass-tree (xanthorrhoea) which plant grows abundantly upon the hills, was covered with them, and on their taking wing the air appeared, as it were, in perfect motion. (*Footnote. Hawkesworth volume 3 page 125.) It is a new species, and is described by my friend Mr. W.S. Macleay, in the Appendix, under the name of Euploea hamata.
