A Voyage to Terra Australis. Matthew Flinders

and up the principal one, in the north-east corner, I went two miles with the boat. The water was there found to be fresh, and the depth sufficient to allow of its being reached by the sloop; but the banks being steep and channel narrow, I was deterred from watering in this place, by the fear of detention from foul winds.

      The width of the Derwent abreast of Herdsman's Cove is half a mile; but except a very narrow channel close to the eastern shore, it is too shallow even for boats. The intention of proceeding further with the sloop was therefore abandoned; but so soon as the rainy, blowing weather permitted, which was not until the 28th, I accompanied Mr. Bass in a boat excursion up the river. Three miles above Herdsman's Cove the banks open out to a mile in width; the river, from running north-westward, turns to the south-west; and the deep channel makes a short cut across to the convex bank, leaving the mud to collect in the opposite elbow. A great deal of long, aquatic grass growing upon these mud flats, seemed to have attracted the black swans, for the number collected there was not estimated at less than five hundred.

      The width of the Derwent is contracted in the south-west reach to little more than a quarter of a mile, and we had not rowed far up it before the water became perfectly fresh. The land on both sides rises to hills of moderate elevation, and the rather steep acclivities being well clothed with verdure, they had an agreeable appearance. Our attention was suddenly called from contemplating the country, by the sound of a human voice coming from the hills. There were three people; and as they would not comply with our signs to come down, we landed and went up to them, taking with us a black swan. Two women ran off, but a man, who had two or three spears in his hand, stayed to receive us, and accepted the swan with rapture. He seemed entirely ignorant of muskets, nor did any thing excite his attention or desire except the swan and the red kerchiefs about our necks; he knew, however, that we came from the sloop, and where it was lying. A little knowledge of the Port Jackson, and of the South-Sea-Island languages was of no use in making ourselves understood by this man; but the quickness with which he comprehended our signs spoke in favour of his intelligence. His appearance much resembled that of the inhabitants of New South Wales; he had also marks raised upon the skin, and his face was blackened and hair ruddled as is sometimes practised by them. The hair was either close cropped, or naturally short; but it had not the appearance of being woolly. He acceded to our proposition of going to his hut; but finding from his devious route and frequent stoppages, that he sought to tire our patience, we left him delighted with the certain possession of his swan, and returned to the boat. This was the sole opportunity we had of communicating with any of the natives of Van Diemen's Land.

      At one o'clock, when advanced five miles above the elbow, the ebb tide made; and the wind being unfavourable, we landed to dine. The general course of the river had been nearly south-west; but it there turned west-by-north. The width, found by extending a base line, was two hundred and thirty yards, and the depth, as it had generally been in the channel from Herdsman's Cove, was 3 fathoms; but in some parts there may not be more than 2, at low water.

      We arrived on board the sloop in the evening, with fourteen swans, in time to get a short distance down the river, before the ebb tide had done running; and no place more convenient than Risdon Cove having offered itself, we anchored there next day, and proceeded to complete our water, and refit the sloop for returning to Port Jackson. The late rains had so much increased the stream at the head of the cove, that our labour was much abridged; and in the evening of Dec. 30, every thing was completed.

      This cove is the highest part of the Derwent to which a ship can advance. There is no danger in proceeding thus far, except off Shoal Point, about two miles below, on the western shore; and on the opposite side, near the echoing cliffs, there are 12 to 17 fathoms. Above Risdon Cove the mud flats commence, and will stop any vessel which draws more than ten or twelve feet; although there be, in some places higher up, from 5 to 8 fathoms. Mount Direction, on the north side of Risdon Cove, forms two round heads which are distinguishable from the entrance of the river, bearing N. 16° W. from Cape Direction. The latitude observed under the mount, from the moon's meridian altitude, was 42° 48' 12" south; variation of the azimuth compass on the south side of the cove, 8° 28', and of the surveying theodolite 9° 15' east; but I found it alter one or two degrees in different places, both in Norfolk Bay and in the Derwent, owing to partial attractions in the land.*

      [* Upon the top of Mount Table, the compass has since been found to vary as much as 20°, from one part of the mountain to another.]

      In Risdon Cove the tide rises between four and five feet, which is more, by at least a foot, than it appeared to be at the entrance of the river. The time of high water is about eight hours after the moon's passage over the meridian, or one hour later than in Adventure Bay.* In the narrow parts, above Sullivan Cove, the tides run with tolerable regularity, and with some degree of strength; but towards the entrance of the river, the water at the surface sometimes ran down twelve hours together, and at other times as much upwards, whilst the rise and fall by the shore were at the usual periods. These anomalies were probably occasioned by the wind, and seemed not to extend far below the surface; for I found a counter current at the bottom.

      [* See Bligh's Voyage to the South Seas; page 53.]

      The banks of the Derwent are not remarkably high, but the country in general may be termed mountainous. Mount Table, at the back of Sullivan Cove, is supposed to be three-quarters of a mile in height; nor do I think, from having seen it beyond the distance of thirty miles from the sloop's deck, that it can be much less. The publication of Mr. Bass' remarks upon the soil and productions of this part of Van Diemen's Land dispenses me from entering upon those subjects; it is sufficient to say, that the reports of them were so favourable as to induce the establishment of a colony on the banks of the Derwent, four years afterward; and that the discoveries which have since been made are marked in the chart.

      1799.

      The last day of December and the first of January were occupied in beating down to the entrance of the river.

      Jan. 2. The wind blew strong from the south-east, with heavy rain; and finding no advantage could be made by beating in Storm Bay, we ran into D'Entrecasteaux's Channel, passed the large North-west Port, and anchored in Pruen Cove, in 4 fathoms. We landed, so soon as the rain cleared away, and found a small creek in which the water was fresh at a few hundred yards above where it falls into the cove. A tree had been felled on the bank, probably in 1793 or 4 by Mr. Hayes, who called this stream Amelia's River; but it would be very difficult to fill casks here, except when long continued rains should bring the fresh water to the entrance of the creek. The valley through which it comes from the westward, seemed to be of a rich, though damp soil.

      On Jan. 3, having a breeze at north-west, we got under way at daylight; and after repassing the northern entrance of D'Entrecasteaux's Channel, steered across Storm Bay. At two clock I had the following bearings:

      Tasman's Head. S. 37° W.

      Cape Frederik Henry, S. 71 W.

      Quoin Island, distant six miles, N. 28 W.

      Low point, distant 1¼ miles, N. 6 E.

      Cape Raoul,* distant 3 miles, S. 71 E.

      [* This is the cape which, from its appearance, I had called by the descriptive name of Cape Basaltes; not knowing that D'Entrecasteaux, or any other navigator, had previously affixed an appellation. I give it up the more readily, because it is said these columns are not strictly basaltes.]

      Cape Pillar opened round Cape Raoul at E. 5° N., and the distance run from one to the other was nine miles. These two high, columnar capes are the extreme points of the land which captain Furneaux took to be Maria's Island. Between them, the shore falls back about four miles, and forms a small bay at the head, where there appeared to be shelter against all winds except those from the southward; and perhaps from those also, for the water seemed to reach behind the inner western point. At five clock we passed Tasman's small, cliffy Island and Cape Pillar, and Maria's Island came in sight at N. 6° E. We then hauled up to keep close in with the shore to the northward; but the wind came in such violent puffs down those steep cliffs, that the necessity of steering further off frustrated my intention: the outer Hippolite Rock bore N. 56° W. three miles, at dusk.

      Jan. 4. At daylight, Maria's Island appeared
