A large patch of bare sand terminates the sandy shores of this coast in latitude 27 degrees 55 minutes. A steep cliff then commences and extends for eight miles to the Red Point of Vlaming; behind which is a bight, called by the French Gantheaume Bay; in the south part of which there appeared a small opening. This bay did not seem to be so well calculated for taking shelter in from southerly gales, as Van Keulen's chart indicates; since it is exposed to winds from South-West by South, from which quarter it must frequently blow. The country appeared very rocky; the slight vegetation covering its surface gave it a greenish hue, but no trees were seen near the shore which is fronted by a sandy beach; the depth of the bight is probably five or six miles. The cliffs of Red Point partake of a reddish tinge and appear to be disposed nearly in horizontal strata. In the centre and about halfway between the base and summit of the cliffs is a remarkable block of stone, of very white colour, that at a distance appeared to be either a fort or house: some black marks on its face took our attention and resembled characters of a very large size, as if they had been painted for the purpose of attracting the attention of vessels passing by; but a closer examination with the telescope prove them to be only the shadows of the projecting parts of the surface.
At half-past seven o'clock we hauled off for the night and, standing off and on, sounded in between thirty-three and thirty-five fathoms.

At daylight the next morning the land bore from East to East-South-East but the morning and forenoon were so hazy that it was very indistinctly seen; at noon a partial clearing away of the haze exposed to our view a long range of high and precipitous cliffs, the base of which was washed by the sea, breaking upon it with a tremendous roar, and heard distinctly by us. The wind falling in the afternoon induced me to stand off shore, when we soon lost sight of the land. At noon we were in latitude 27 degrees 5 minutes 18 seconds. At one o'clock the depth was forty-five fathoms fine gray sand. No land was seen during the rest of the day; for although the sky was beautifully clear and serene, the atmosphere for fifteen degrees above the horizon was enveloped in a thick hazy mist that caused an extraordinary dampness in the air, and from the unfavourable state of the weather we did not attempt to make it again.

The next morning we saw that part of Dirk Hartog's Island which lies in 25 degrees 56 minutes, and when we had reached within four miles of the shore steered to the northward parallel to the beach, but the haze was still so great as to render the land very indistinct. We saw enough of it however to be convinced of its perfect sterility. The coast is lined with a barrier of rocks on which the sea was breaking high with a roar that was heard on board although our distance from the shore was at least three miles.
The warmth of the weather now began rapidly to increase; the thermometer at noon ranged as high as 79 degrees.
At one o'clock Cape Inscription, the north-westernmost point of Dirk Hartog's Island, was distinguished and the sea-breeze veered as far as South-West by West, which was two points more westerly than we had hitherto had it. At two o'clock the brig passed round the cape and, as there was an appearance of good shelter in the bay to the eastward of it, we hauled in and at half-past three o'clock anchored in twelve fathoms fine gravelly soft sand; the west point of Dirk Hartog's Island (Cape Inscription) bearing North 82 degrees West, and the low sandy point that forms its north-east end South 53 degrees West, at a mile and a half from the shore.
As we hauled round the cape and were passing under the lee of the land the breeze became so suddenly heated, by its blowing over the arid and parched surface of the coast, that my seaweed hygrometer, which had been quite damp since we left Rottnest Island, was in ten minutes so dried as to be covered with crystals of salt; and in this state it continued during our stay.
Upon rounding the cape two posts were descried upon its summit, which we conjectured to be those on which the French had affixed a record of their visit, as well as the more ancient one of the Dutch navigators, Dirk Hartog and Vlaming; for they were very conspicuously placed and appeared to be in good preservation.
