The peak of Cape Barren was set at N. 28 40 E.
Mount Chappell, N. 21 20 W.;
from which, and several intermediate bearings, this station became firmly connected with the survey of Furneaux's Islands. Mr. Bass thought the stone to contain a rather large quantity of iron, and the bearings seemed to confirm it, for they did not agree in any common intersection with the allowance of 9° east, which I considered to be the true variation; but with 6° 30', they not only coincided, but placed this station in latitude 40° 43' south, the same as deduced from three meridional observations taken within sight of the island.
One mile from the north-west end, lies a low, rocky islet, and several rocks both above and under water. All these are comprehended under the general name of the Swan Isles; a name which, on examination, they appeared very little to deserve, for we did not see a single bird of that species, or any of their nests; but there were several of the bernacle geese, and two of them were shot by Mr Bass.
The length of the largest Swan Isle is two and a quarter miles, by a medium breadth of one mile. The stony parts are over-run with thick brush wood, and the sandy are mostly covered with hassocks of wiry grass, to which the sooty petrels resort. In external appearance, this island bears a resemblance to that of Preservation; but its sterility is greater, and it is destitute of the kangaroo. We did not see any fresh water in the valleys, a seal upon the shores, nor any marks of the island having been ever visited by the natives of the opposite coast.
Nov 1. Having an unfavourable wind, I waited the flood tide, and then proceeded westward, along that part of Van Diemen's land to which the name of CAPE PORTLAND was given, in honour of His Grace the then secretary of state for the colonies. From the eastern extremity, the coast trends about N. 62° W. six leagues, and terminates in a point, off which lie some small rocky islets. The shore consists of long, sandy beaches, separated by low and stony points, which project very little beyond the coastline. The country for two or three miles behind the shore is low and sandy; but it then ascends in gradations of gently rising hills, and being covered with verdure, interspersed with clumps of wood and single trees of a fair growth, it had a very pleasing appearance. At the back of these hills, the bare and rugged tops of a ridge of distant mountains appeared here and there, and formed a striking contrast with the verdure of the front scene.
Our soundings along the south side of the largest Swan Isle were generally 8 fathoms, on a sandy bottom; nor was there much decrease until noon, when the low shore of Cape Portland was at something less, and the outer rocky islets something more than a mile distant, and we came rather suddenly into 3 fathoms. The latitude observed was 40° 43 2/3' south, and the island last quitted bore N. 85° to S. 84° E., distant six miles.
There being little wind at this time, the sloop, in passing round the rocky islets of Cape Portland, was carried by the tide over a ledge where there was scarcely 2 fathoms; and was then driven westward on a curved line of rippling water, which extended northward from the islets as far as the eye could reach. We passed over the rippling in 9 fathoms; and the wind being entirely gone, were then carried to the south-west.
Soon after four o'clock, the ebb appeared to be making; and the anchor was dropped in 11 fathoms, sandy bottom, about one mile west of Cape Portland. The shore on this side of the cape trends south, in rocky heads and beaches, and afterwards curves westward, forming an extensive bay, which terminates in a point. To this the name of Point Waterhouse was given, in honour of the commander of the Reliance, and an island, whose top is level and moderately high, lying off the point, was named ISLE WATERHOUSE.
The bottom of the large bay is sandy, and the hills of Cape Portland there retiring further back, permitted a view of the inland mountains, of which there was a high and extensive ridge. Mountains like these are usually the parents of rivers; and the direction of the ebb tide, which came from between S.W. by S. and S.W. by W. at the rate of two-and-a-half miles an hour, gave hopes of finding some considerable inlet in the bay, and increased our anxiety for a fair breeze.
A set of distances of the sun east of the moon, a meridian altitude of the planet Mars, and a western amplitude of the sun were taken at this anchorage, the results of which, with the bearings of the land, were as under:
° '
Latitude observed, 40 44 S.
Longitude from lunar distances corrected, 147 56 E.
Variation of the compass (the sloop's head being S.W.) 12 30 E.
C. Barren peak, over the outer islets of C. Portland, N. 47 E.
Mount Chappell, North.
Isle Waterhouse, centre, dist. 5 or 6 leagues, S. 71 W.
Point Waterhouse. S. 61 W.
Ridge of inland mountains, South to S. 42 W.
Highest part of ditto, a round top, S. 19 W.
The flood tide ceased to run at three quarters past three in the morning, or about nine hours after the moon passed over the meridian.
Nov. 2. A light breeze having sprung up from the eastward we steered for the bottom of the bay, and at noon the nearest part of the beach was distant only two miles.

Observed latitude, 40 49¾ S.
C. Portland, with the outer islets behind, N. 27 E.
Isle Waterhouse, extremes, N. 78° to 89 W.
Point Waterhouse, S. 88½ W.
We stood on another mile, and then bore away westward, following the round of the shore, but no inlet could be perceived. At three o'clock, we had passed Point Waterhouse, and seeing a fair channel of about two miles wide between it and the island, steered through, S.W. by W.
Isle Waterhouse is near four miles in length. Its southern shore consists of beaches and rocky points; but it rises abruptly to a moderate elevation. The level top is mostly covered with wood; and although its appearance did not bespeak fertility, it was superior to any we had seen of Furneaux's Islands. The land at the back of Point Waterhouse is higher than that of the island, and is composed of grassy, woody hills, rising over each other by gentle ascents. Upon the point there is a sandy hillock, and a reef of rocks extends out from it a quarter of a mile. We had 8 fathoms, whilst rounding this reef; and in steering through the passage, the soundings were 8, 7, 6, 5, 4, 5, 6 fathoms; the sandy bottom being visible under the sloop. At the further end of the channel, a rocky islet and a small reef were passed, leaving them on the starbord hand. The islet was almost covered with sea birds and hair seals; from which circumstance we judged, that the natives of Van Diemen's Land were not able to get across here, any more than to the Swan Isles; and that, consequently, they had no canoes upon this part of the coast.
From Point Waterhouse, the shore trends S. 67° W., five or six miles, and is mostly rocky. It then takes a direction of S. S. W., in a long sandy beach, and afterwards curves westward to a projecting point, near which we had no ground with 13 fathoms a little before sunset. Another island had been for some time visible, and was then distant six miles: It was called
Ninth Island, and bore N. 32° W.
Isle Waterhouse, about the centre, N. 50° E.
South side of the passage, N. 62° E.
Projecting point, dist. one-third of a mile, South.
The projecting point is over-topped with hillocks of almost bare sand, as is a second, which lies W. 6° S., two or three miles from, and much resembles, the first: these two projections received the joint name of Double Sandy Point. The back country was manifestly worse than any before seen on this coast. The pleasant looking hills of Point Waterhouse no longer approached the shore; but retiring far inland, left a low space between the back hills and the sea, which had every appearance of being sandy and barren.
In passing the western part of Double Sandy
