A Voyage to Terra Australis. Matthew Flinders

who have seen a farm yard, well stocked with pigs, calves, sheep, oxen, and with two or three litters of puppies, with their mothers, in it, and have heard them all in tumult together, may form a good idea of the confused noise of the seals at Cone Point. The sailors killed as many of these harmless, and not unamiable creatures, as they were able to skin during the time necessary for me to take the requisite angles; and we then left the poor affrighted multitude to recover from the effect of our inauspicious visit.

      My 8th station was taken, in returning to the schooner, upon the south end of the eastern Passage Isle; 9th, the south-west end of the western Passage Isle; and 10th, the south-east point of Clarke's Island. The 11th and last station was at Look-out Head, the bearings from which included some parts of the southern land, between the extremes of S. 20° 20' E. and S. 59° 35' W. At these different stations, the needle of the theodolite was sometimes found to vary one or two degrees from itself, as it had done at Preservation Island; an effect which I attribute to the attraction of the rocks, having since experienced the same, and even greater, differences in most places where the rocks, as here, are granitic.

      In the wider parts of Armstrong's Channel there are many shoals of sand on each side, but a passage of sufficient width and depth is swept out by the tides, for ships to go through in safety. The bottom is either rocky or sandy: rocky in the deep and narrow parts, where the tides run three or four miles in an hour; and sandy in the bights and shoaler places. The sand of the beaches is mostly granitic, but it sometimes consists of black metallic particles, such as are found in the stone of the islands.

      It was not until Feb. 25 that the remains of the Sydney-Cove's cargo were all on board, and that a favourable change in the wind permitted us to sail for Port Jackson. These four days of detention enabled me to continue the survey along the south side of Preservation Island, and as far as the Bay of Rocks upon that of Cape Barren. A meridian altitude from the south horizon, observed under more favourable circumstances than two others before taken, gave 40° 28' for the latitude of Hamilton's Road. The longitude is 19' 20" west of Cape Barren; and therefore should be 148° 6' east of Greenwich. It is high water in the road, according to Mr. Hamilton's report, half an hour before the moon passes over the meridian; but from what I observed, without paying particular attention to it, the tide did not appear to flow so late by an hour: the medium rise was about seven feet, as at Port Jackson.

      Well tasted fresh water is collected, at certain seasons, in small pools near the east end of Preservation Island; but that which drains from the rocks was first used by the Sydney-Cove's crew, until several of them died. Small runs or pools of water are to be found almost every where under the high parts of Cape-Barren Island, and it is probable there may be some upon Clarke's Island; but at the Passage Isles we found it difficult to obtain wherewithal to satisfy our thirst.

      The stone of which the southern, and probably the whole of Furneaux's Islands are composed, is mostly a whitish granite, but sometimes inclining to red; and is full of small, black specks. Quartz seems to have a more than usual share in its composition, and we occasionally found crystals of that substance upon the shores. The black specks were thought to be grains of tin, and to have communicated a deleterious quality to the water used by the shipwrecked people. The exceptions to the general prevalence of granite were few: they consisted of some black, and some grey slate, in thin strata, placed nearly perpendicular to the horizon; but even here, the granite had pervaded the fissures of the strata; and, in two instances, a substance which, from its appearance, I supposed to be a toad stone, had insinuated itself.

      Some of the trees on Preservation Island had partly undergone a peculiar transformation. The largest of them were not thicker than a man's leg, and the whole were decayed; but whilst the upper branches continued to be of wood, the roots at the surface, and the trunks up to a certain height, were of a stony substance resembling chalk. On breaking these chalky trunks, which was easily done, rings of the brown wood sometimes appeared in them, as if imperfectly converted; but in the greater number, nothing more than circular traces remained. The situation in which these trees were principally found, is a sandy valley near the middle of the island, which was likewise remarkable for the quantity of bones of birds and small quadrupeds, with which it was strewed. The petrefactions were afterwards more particularly examined by Mr. Bass, who adopted the opinion that they had been caused by water.

      Upon Cape-Barren Island the hills rise to a considerable height, that of the peak, which does not much exceed some others, being near twelve hundred feet; but on the smaller islands there is no elevation of importance. The upper parts of all are generally crowned with huge lumps of granite; and upon many of these, particularly on Rum Island, is a smaller, unconnected, round lump, which rests in a hollow at the top, as a cup in its saucer; and I observed with a glass, that there was a stone of this kind at the summit of the peak of Cape Barren. The lower parts of the islands are commonly sandy; and, in several places under the hills, swamps and pools are formed. The water in these is generally tinged red; and in one, situate between Passage and Cone Points, it had so much the appearance of blood, that I went to taste it; but, except being a little brackish, found nothing remarkable. Whether the water become thus tinged, in its course down the hills, by earthy or metallic substances, or acquire its colour from the roots and leaves of vegetables, I am unable to decide; but think the former most probable.

      All the islands are over-run with brush wood, amongst which, in the more sheltered and less barren parts, are mixed a few stunted trees, which seem to shed their bark annually, and to be of the heavy kind called gum tree at Port Jackson. The brush wood overspreads even the rocks where it can get the least hold; it is commonly impenetrable, and on the south and west sides of the islands assumes a depressed, creeping form, strongly indicative of the strength and generality of the winds from those quarters. Many of the sandy parts are covered with the hassocks of wiry grass, which constitute the favourite retreat of the sooty petrel; and at the back of the shores, there is frequently some extent of ground where the creeping, salt plants grow, and to which the penguins principally resort. To this general account of the scanty vegetable productions of Furneaux's Islands, may be added several low shrubs, and a grass which grows on the moist grounds near the borders of the pools and fresh swamps, and which, though coarse, might serve as food for cattle.

      Of the animal productions of the islands, the list is somewhat more extensive. Those for which they are indebted to the sea, are seals of two kinds, sooty petrels, and penguins. The hair seal appears to frequent the sheltered beaches, points, and rocks; whilst the rocks and rocky points exposed to the buffettings of the waves are preferred by the handsomer and superior species, which never condescends to the effeminacy of a beach. A point or island will not be greatly resorted to by these animals, unless it slope gradually to the water, and the shore be, as we term it, steep to. This is the case with the islet lying off Cape Barren, and with Cone Point; with parts of the Passage Isles, and the south end of Clarke's Island; and at these places only, did I see fur seals in any number.

      The sooty petrel, better known at sea under the name of sheerwater, frequents the tufted, grassy parts of all the islands in astonishing numbers. It is known that these birds make burrows in the ground, like rabbits; that they lay one or two enormous eggs in these holes, and bring up their young there. In the evening, they come in from sea, having their stomachs filled with a gelatinous substance gathered from the waves; and this they eject into the throats of their offspring, or retain for their own nourishment, according to circumstances. A little after sunset, the air at Preservation Island used to be darkened with their numbers; and it was generally an hour before their squabblings ceased, and every one had found its own retreat. The people of the Sydney Cove had a strong example of perseverance in these birds. The tents were pitched close to a piece of ground full of their burrows, many of which were necessarily filled up from walking constantly over them; yet, notwithstanding this interruption, and the thousands of birds destroyed, for they constituted a great part of their food during more than six months, the returning flights continued to be as numerous as before; and there was scarcely a burrow less, except in the spaces actually covered by the tents. These birds are about the size of a pigeon, and when skinned and dried in smoke we thought them passable food. Any quantity could be procured, by sending people on shore in the evening. The sole process was to thrust in the arm up to the shoulder, and seize them briskly; but there was some danger of grasping a snake at the bottom of the burrow, instead of a petrel.
