These islets are in fact only the dry parts of a shoal, on which the sand has accumulated, and formed a soil to receive and nourish the seeds of plants, which have either been drifted on shore by the tide, or been brought by birds from the continent.
At sunset we anchored under the land, but soon afterwards the wind blew so fresh, that the fluke of our anchor broke, and we were obliged to drop another; which was the last we possessed, besides a small stream anchor that was too light to use, excepting in a calm.

The next morning being fine, and favourable for another search after our lost anchor (the recovery of which from our last night's misfortune had become of very great consequence) we bore up along the shore, and soon arrived at the spot; but after some time spent in the search, without success, we were at last obliged to relinquish the attempt, and gave up all hope of ever finding it.

We then returned into the gulf to prosecute its examination, but as usual, the wind fell, and the only progress we made was by the assistance of the flood-tide, which ran until sunset; a fresh breeze then sprung up, and the night was passed under sail.

At daylight the following morning the cutter was about four miles from the western shore, but the day was so calm that very little progress was made.

The thermometer indicated a temperature of 97 degrees, which, from the absence of the sea-breeze, and from our not having an awning to protect us from the sun's rays, was almost insufferable; and although our crew were happily in good health, yet my fears were momentarily alive lest any should be taken ill.

A land-wind at night enabled us to make some progress, and before dark we had reached twenty-five miles into the opening without seeing anything like its termination; the western side still trended in a southerly direction, losing itself in distance, and bore the appearance of being an island.
February 15.
By the next day we descried some hills of peaked shape to the southward, which was the only indication we had of the termination of the gulf: to the eastward the islands were very numerous and low; but to the South-East the land was so continuous as to impress us with the idea of its being the continent.

We steered towards it to satisfy our doubts but the water shoaled and prevented our approaching it near enough to ascertain the fact.
