At two o'clock the shore again took a northern direction, but it was still very low in front, and the depth did not materially increase. Land was presently distinguished on the starbord bow and beam; and before four, an elevated part, called Barn Hill from the form of its top, bore E. 4° N. We continued to follow the line of the western shore, steering north-north-east and north; and the wind being at south, we hauled north-westward at six o'clock, intending to anchor under the shelter of the land. From 7 fathoms the depth diminished to 5, and quickly to seventeen feet; upon which we veered round, ran back into 5 fathoms, and came to an anchor three or four miles off the shore on a sandy bottom. The wind blew fresh, with rainy squalls; but a whole cable being veered out, we rode smoothly all night. The furthest land visible to the northward consisted of detached hummocks of which the highest was called Mount Young in honour of the admiral. Abreast of the ship the land rose gradually from the beach to the ridge of hills which still continued to run behind it; but at this place some back hills were visible over the ridge; and the highest of several hummocks upon the top, which served as a mark in the survey, was named Middle Mount. Observations for the time keepers were taken in the morning [TUESDAY 9 MARCH 1802] before getting under way, and the situation of the anchorage was found to be in
Longitude, 137° 27½'
Mount Young bore, N. 11 E.
Middle Mount, N. 62½ W.
Low western shore, extreme, S. 21 W.
High eastern land, about the middle, N. 71 E.
Having obtained the observations, we steered for the outermost of the northern hummocks, with soundings gradually increasing to 12 fathoms; but shoaling on a sudden to 7, upon coral, we hauled to the wind and tacked instantly; finding, however, that the depth did not further decrease, I let the ship go entirely round, and continued the former north-eastern course, with soundings from 7 to 9 fathoms.
At noon, the furthest hummock seen from the anchorage was distant four or five miles; it stands on a projection of low sandy land, and beyond it was another similar projection to which I gave the name of Point Lowly. This was the furthest visible part of the western shore; but the eastern land there approached within seven or eight miles, and extended northward, past it, in a chain of rugged mountains, at the further end of which was a remarkable peak. Our situation and bearings at this time were as follow:
Latitude, observed to the north and south, 33° 5' 14"
Longitude by time keepers, 137 41 1/3
Middle Mount, S. 75 W.
Mount Young, S. 87 W.
Point Lowly, the extreme, N. 43 E.
High peak on the eastern land, N. 25 E.
Our prospect of a channel or strait, cutting off some considerable portion of Terra Australis, was lost, for it now appeared that the ship was entered into a gulph; but the width of the opening round Point Lowly left us a consolatory hope that it would terminate in a river of some importance. In steering for the point we came into 4 fathoms, but on hauling to the eastward found 8, although a dry sand-bank was seen in that direction. The depth afterwards diminished to 6, on which the course for Point Lowly was resumed; and we passed it at the distance of a mile and a half, in 9 fathoms water. Here the gulph was found to take a river-like form, but the eastern half of it was occupied by a dry, sandy spit and shoal water. We continued to steer upwards, before the wind; but as the width contracted rapidly, and there was much shoal water, it was under very easy sail, and with an anchor ready to be let go. At four o'clock, in attempting to steer close over to the western side, we came suddenly into 2½ fathoms; the ship was instantly veered to the eastward, and on the water deepening to 7, we let go the anchor and veered out a whole cable; for the wind blew a fresh gale right up the gulph, and between S. 4° W. and 30° E. there was no shelter from the land. At sunset a second anchor was dropped under foot.
We had reached near five leagues above Point Lowly, at the entrance of the narrow part of the gulph; but the shores were low on both sides, and abreast of the ship not so much as four miles asunder. At the back of the eastern shore was the ridge of mountains before mentioned, of which Mr. Westall made the sketch given in the Atlas (Plate XVII. View 10.); and the highest peak toward their northern extremity, afterwards called Mount Brown, bore N. 32° E. On the western side, upwards, there was moderately high, flat-topped land, whose eastern bluff bore N. 36° W., about three leagues, and there the head of the gulph had the appearance of terminating; but as the tide ran one mile an hour past the ship, we still flattered ourselves with the prospect of a longer course, and that it would end in a fresh-water river.
WEDNESDAY 10 MARCH 1802
Early on the following morning, Messrs. Brown, Bauer and Westall, with attendants, set off upon an excursion to the eastern mountains, intending, if possible, to ascend to the top of Mount Brown; and I went away in a cutter, accompanied by the surgeon, to explore the head of the gulph, taking with me Arnold's pocket time-keeper. After crossing the middle shoal, upon which we had 2½ fathoms in the ship, the water deepened to 10, but afterwards diminished to 2, on approaching the mangroves of the western side. Keeping then upwards, I had from 7 to 10 fathoms in the mid-channel, but found shoal water extending a mile, and sometimes more, from the shore and no possibility of landing until we came near the broad, flat-topped hill. From the eastern bluff of this hill, Mount Brown bore N. 62° 20' E., and Mount Arden, a peak nearly at the furthest extreme of the ridge, N. 18° 40' E.; and the inlet was seen to run in a serpentine form to the northward, between low banks covered with mangroves. After taking the bearings we returned to the boat and pursued our course upward along the western shore, having from 4 to 7 fathoms past the bluff; but the inlet was there less than two miles wide, and a league further on it was contracted to one mile, half of which, besides, was occupied by mud flats. These banks were frequented by ducks and other water fowl; and some time being occupied in chasing them, our distance above the ship was not so much as five leagues in a straight line, when the setting sun reminded us of looking out for a place of rest. A landing was effected with some difficulty amongst the mangroves on the eastern shore; and from a small eminence of red earth I set the ship's mast heads at S. 14° E., and Mount Brown N. 85° E.
