Seeing breakers to the S.S.W., which I was desirous of knowing the extent of before night, I left Turtle Isle, and stood for them. At two o'clock we found they were occasioned by a coral bank, of about four or five leagues in circuit. By the bearing we had taken, we knew these to be the same breakers we had seen the preceding evening. Hardly any part of this bank or reef is above water at the reflux of the waves. The heads of some of the rocks are to be seen near the edge of the reef, where it is the shoalest; for in the middle is deep water. In short, this bank wants only a few little islets to make it exactly like one of the half-drowned isles so often mentioned. It lies S.W. from Turtle Island, about five or six miles, and the channel between it and the reef of that isle is three miles over. Seeing no more shoals or islands, and thinking there might be turtle on this bank, two boats were properly equipped and sent thither; but returned without having seen one. The boats were now hoisted in, and we made sail to the west, with a brisk gale at east, which continued till the 9th, when we had for a few hours, a breeze at N.W., attended with squalls of rain. This was succeeded by a steady fresh gale at S.E., with which we steered N.W., being at this time in the latitude of 20 deg. 20' S. longitude 176 deg. 8' E. On the 15th at noon, being in the latitude of 15 deg. 9' south, longitude 171 deg. 16' east, I steered west. The next day the weather was foggy, and the wind blew in heavy squalls, attended with rain, which in this ocean, within the tropics, generally indicates the vicinity of some high land. This was verified at three in the afternoon, when high land was seen bearing S.W. Upon this we took in the small sails, reefed the top-sails, and hauling up for it, at half-past five we could see it extend from S.S.W. to N.N.W. half W. Soon after we tacked and spent the night, which was very stormy, in plying. Our boards were disadvantageous; for, in the morning, we found we had lost ground. This, indeed, was no wonder, for having an old suit of sails bent, the most of them were split to pieces; particularly a fore-top-sail, which was rendered quite useless. We got others to the yards, and continued to ply, being desirous of getting round the south ends of the lands, or at least so far to the south as to be able to judge of their extent in that direction. For no one doubted that this was the Australia del Espiritu Santo of Quiros, which M. de Bougainville calls the Great Cyclades, and that the coast we were now upon was the east side of Aurora Island, whose longitude is 168 deg. 30' E.
