shore; but not being able to find an anchorage we continued under weigh during the night. September 14. The next morning the land was not in sight: as we stood towards the shore it was soon afterwards discerned, and at noon we were very near to our last night's position but were prevented from steering towards Lacrosse Island by a considerable shoal which extended to the North-West and crossed our course: we anchored near it at sunset in ten fathoms. The land this day was more visible towards the South-East and observed to join the low land at the back of the reefs that we passed on the 12th. A remarkable echo was heard in the evening: whilst the cook was chopping his wood every blow was echoed round the bight, although we were eight miles from the shore. After leaving Port Keats we met with large quantities of a very beautiful species of medusa, it appeared to be the Medusa panopyra, figured in Peron's Atlas, (Plate 31 figure 2). It is from this animal that the French have named their Banc des Meduses. No turtle or snakes had for some time been seen and very few sharks; but other fish were numerous. September 15. Very little progress was made the next day; several attempts were made to stand toward Lacrosse Island; but we were obliged to give it up as the bank still crossed our course. In the evening we again anchored near the edge of the bank and during the night the breeze blew fresh but the anchor held well. September 16. At daylight another ineffectual attempt was made to cross the bank. At two o'clock we passed several detached banks on which were seven and eight fathoms; and soon afterwards rounded the north-west end of the large bank, at a quarter of a mile distance in four fathoms; after which the water deepened to twelve and thirteen fathoms but still the bottom was of hard sand. From the colour of the sea it appeared that we were in a deep channel, extending towards Lacrosse Island: from light winds our progress was so slow that sunset overtook us before we had formed any plan for anchoring; our soundings were between twenty-two and eighteen fathoms hard sandy bottom: the tide was ebbing. The idea of standing out for anchorage after having toiled for the last three days against foul winds and other obstacles was particularly revolting; and increasing darkness found me quite at a loss what course to pursue; for Lacrosse Island appeared so rocky that I despaired of finding anchorage near it: having however two days before seen a white beach off its south-east end (which subsequently proved to be composed of stones whitened by the effect of the weather) we stood towards it as a last resource; and on our way thither we passed over a muddy bottom upon which the anchor was dropped in eight fathoms, at about two miles from the north-west end of the island. This day as usual many medusae were seen; and also a snake, three feet long; its back was black, the belly yellow, and the tail striped black and white. September 17.
