off this point lies a flat, rocky islet and a peaked rock. The shore is sandy on each side of the Cape point: it trends N. 40° W., for about five miles, on one side, and S. 49° W., past two sandy bights on the other, to a rocky projection on which are two whitish cones, shaped like rhinoceros' horns.
We steered south-westward, in the evening, round the Cape point, and were sufficiently close to hear the bellowing of the seals upon the islet. Arrived off Cone Point, the schooner was hauled offshore; and the wind becoming strong and unfavourable in the night, it was not until the evening of the 12th, that we got to anchor in Hamilton's Road, at the east end of Preservation Island. This road is sheltered from all winds, except between south and S. S. E.; and these do not throw in much sea: the bottom is good-holding sand, in from 4 to 3 fathoms, at a quarter of a mile from the beach.
The ship Sydney Cove had been run on shore between Preservation and Rum Islands, and part of her hull was still lying there; but the sea thrown in by western gales had, in great measure, broken her up, and scattered the beams, timbers, and parts of the cargo, upon all the neighbouring shores.
My purpose of making an expedition amongst the islands was delayed by the schooner's boat being out of repair; but in the mean time, a base line was measured round the sandy north-east end of Preservation Island, and angles taken from all the conspicuous points.
Feb. 16. The boat was fitted, and I made an excursion of five days, through the channel which separates the land of Cape Barren from the more southern islands. It is called ARMSTRONG'S CHANNEL, from the master of the Supply, who had gone to afford assistance in saving the cargo of the Sydney Cove, and was the first to pass through it on his return towards Port Jackson; but he never arrived there, having, in all probability, perished at sea with his sloop and crew. The stations whence angles were taken for a survey of the channel and surrounding lands, were--1st. Point Womat, a rocky projection of Cape-Barren Island, where a number of the new animals, called womat, were seen, and some killed. 2nd. Battery Island; so named from four rocks upon it, resembling mounted guns; sooty petrels, and large hair seals were found there. 3rd. The sandy north-east point of Clarke's Island; which, with the opposite Sloping Point, forms the narrowest part of the channel. Its width was found to be three-quarters of a mile, but is somewhat contracted by rocks lying on the south side. These rocks were also frequented by hair seals, and some of them (the old males) were of an enormous size, and of extraordinary power. I levelled my gun at one, which was sitting on the top of a rock with his nose extended up towards the sun, and struck him with three musket balls. He rolled over, and plunged into the water; but in less than half an hour had taken his former station and attitude. On firing again, a stream of blood spouted forth from his breast to some yards distance, and he fell back, senseless. On examination, the six balls were found lodged in his breast; and one, which occasioned his death, had pierced the heart: his weight was equal to that of a common ox.
The 4th station was on Sloping Point, where an aculeated ant-eater was caught, and some quartz crystals were picked up from the shore. 5th, At the east side of Kent's Bay, under the peak of Cape Barren. This peak I wished to ascend, in order to obtain a view of the surrounding lands, particularly of an extensive piece to the southward, which, from the smokes continually seen there, was supposed to be a part of Van Diemen's Land; but the almost impenetrable brush wood, with which the sides of the peak and surrounding hills were covered, defeated my purpose.
The 6th station was at Passage Point. The 7th, on Cone Point, where the number of seals exceeded every thing we had, any of us, before witnessed; and they were smaller, and of a different species from those which frequented Armstrong's Channel. Instead of the bull-dog nose, and thinly-set, sandy hair, these had sharp-pointed noses, and the general colour of the hair approached to a black; but the tips were of a silver grey, and underneath was a fine, whitish, thick fur. The commotion excited by our presence, in this assemblage of several thousand timid animals, was very interesting to me, who knew little of their manners. The young cubs huddled together in the holes of the rocks, and moaned piteously; those more advanced scampered and rolled down to the water, with their mothers; whilst some of the old males stood up in defence of their families, until the terror of the sailors bludgeons became too strong to be resisted. Those 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
