Behind Point Gantheaume the land appeared to be formed by downs of very white sand; and between this point and Cape Boileau is a bay, which at first, from the direction of the flood stream at the anchorage, was conjectured to be an inlet; but as the tide afterwards set to the Northward and North-East, it was concluded to be occasioned by the stream sweeping round the shores of the bay: according to the depth alongside there was a rise of ten feet; after high-water the ebb set between North 1/2 West and North-North-East, at the rate of a quarter to three quarters of a knot. During the whole day the horizon was occupied by haze, and produced a very remarkable effect upon the land, which was so raised above the horizon by refraction that many distant objects became visible that could not otherwise have been seen. This mirage had been frequently observed by us on various parts of the coast, but never produced so extraordinary an effect as on the present occasion. The coastline appeared to be formed of high chalky cliffs, crowned by a narrow band of woody hillocks; and the land of Cape Villaret was so elevated as to be distinctly seen at the distance of forty miles, whereas two days afterwards, the weather being clear, it was not visible above the horizon for more than five leagues. This state of the atmosphere caused a rapid evaporation during the day, and as the evening approached a very copious dew commenced falling, which by sunset was precipitated like a shower of rain. The next morning the land was again enveloped in haze, but at seven o'clock it cleared off a little, and the coast was observed to trend round Point Gantheaume to the south-east, but as we had last evening seen it as far to the westward as South-West by South, we steered in the latter direction under the idea of there being no opening to the southward of the point, since the flood-tide flowed from it instead of towards it, as it naturally would have done had there been any inlet of consequence thereabout.
