For several days before anchoring here we had observed large flocks of sooty petrels; and I found the surface of the island, where it was sandy and produced small shrubs, to be full of their burrows. Penguins, similar to those of Furneaux's Islands, had their burrows nearer to the water-side. A small species of kangaroo, was also found, and at some preceding season the island had been frequented by geese; but at this time, the vegetation being almost burnt up, they seemed to have quitted it from want of food. The heat was, indeed, such as to make walking a great fatigue; and this was augmented by frequently sinking into the bird holes and falling upon the sand. The thermometer stood at 98° in the shade, whilst it was at 78° on board the ship.
Where the surface is not of sand it consists of calcareous rock, mostly in loose pieces; but the stone which forms the basis of the island is heavy and of a close grain, and was judged to be porphyry. In the crevices of a low calcareous cliff, at the south-east side of the bay, I found some thin cakes of good salt, incrusted upon a stone containing laminae of quartz.
A party was sent on shore at dusk to collect petrels, and in less than two hours returned with sufficient to give four birds to every man in the ship. Early in the morning [THURSDAY 4 FEBRUARY 1802] the boats were again sent upon the same errand, and to haul the seine; but the birds were gone off to sea for the day, and no fish were caught. A small kangaroo was brought off, as also a yellow snake, which was the second killed on this island. The great heat deterred the naturalists from going on shore this morning, for the very little variety in the vegetable productions presented no inducement to a repetition of their fatigue. I landed to see what further could be discovered of the neighbouring islands; and we then prepared to get under way so soon as the breeze set in from the south-eastward, which it usually did about noon, after a few hours of calm or of light airs.
The small bay in the Isle St. Francis, which I call Petrel Bay, affords excellent shelter for two or three ships; but no fresh water, not even to rinse our mouths, could be found at this time; and a few scattered bushes were the nearest approach to wood upon the island. Petrels, penguins, and a few hair seals may be procured, and probably some geese in the wet season.
I had hitherto observed upon this coast that the south-east and east winds produced the same effect upon the barometer as at the Cape of Good Hope, in keeping the mercury high, commonly at or above 30 inches and the more fresh was the wind, the higher it stood; but within the last few days the barometer was much lower with the same winds, and at this time was at 29.74. The dense haze which prevailed might possibly have caused the change, but I suspected another reason for it. Winds coming off the land, I had remarked, had a tendency to depress the mercury, and sea winds to make it rise, though no change took place in the weather; and it therefore seemed probable, as the trending of the coast beyond these islands was unknown, that the south-east and east winds came off the land, and not from the sea, as before; in which case the unknown coast would be found trending to the southward, a conjecture which, it will be seen, was verified. That there was no entrance to a strait, nor any large inlet near these islands, was almost demonstrated by the insignificance of the tides; for neither in Fowler's Bay nor at this Isle St. Francis could any set be perceived; nor was there any rise by the shore worthy of notice.
At half-past one we left Petrel Bay; and having passed between the small isles to the north-east, steered for Evans' Island, and toward the Isles of St. Peter, which were expected to lie beyond it. At five o'clock, we passed between Evans' Island and some rocks above water, with breakers round them, lying three miles to the eastward. An island, equally high with that of St. Francis, was then seen to the north, and low land extended from it to N. 45° E., which had some appearance of being part of the main. We steered for these lands; and seeing an opening between them at sunset, I attempted it in the hope of getting anchorage for the night; but the water shoaled suddenly, from 4 fathoms to sixteen feet upon rocks, and obliged me to veer on the instant. We then stood back to the southward till eight o'clock, and nothing being perceived in the way of the ship's drift, hove to for the night.
FRIDAY 5 FEBRUARY 1802
The wind was north-east in the morning; and at half-past four o'clock we filled the sails and steered eastward until eight, when the central island of St. Francis bore N. 71° W., and Franklin's Isles, for there are two, besides rocks, were distant four leagues, the small opening between them bearing N. 28° W. To the south-eastward of these islands, at the distance of eleven miles, is a low projection of the main land, to which the name of Point Brown was given, in compliment to the naturalist; and four leagues further, in the same line, was a cliffy head, called Cape Bauer after the painter of natural history. Between these projections there was a wide space where no land was visible, and for which we accordingly steered on the wind veering more to the northward. The atmosphere was still hazy, more especially about the horizon, and no observations worthy of confidence could be taken for either latitude or longitude. At noon,
Franklin's Isles bore N. 48½° to 56½° W.
Point Brown, distant four miles, N. 34 W.
Cape Bauer, south extremity, dist. 3 leagues, S. 50 E.
No land was yet visible ahead; and there being much refuse from the shore, as well as seaweed floating about, some hopes of finding a river were entertained. At half-past two, however, low, sandy land was seen from the mast head, nearly all round, the depth had diminished from 19 to 7 fathoms, and the water was much discoloured in streaks at less than a mile from the ship. Smokes Were rising in three different places; but as the wind was unfavourable, and there was no prospect of any opening sufficiently large to admit the Investigator, I gave up the further examination of this place, and called it STREAKY BAY.
