# A Voyage to Terra Australis/Volume 1/Book 1/Chapter 7

CHAPTER VII.
1802. March. Saturday 6.At ten in the morning of March 6, we sailed out of Port Lincoln, and skirted along the east side of Boston Island and the entrance of Louth Bay, In the afternoon we passed within two miles of Point Bolingbroke; and at six in the evening came to an anchor in 10 fathoms, off the north side of Kirkby Island, which is the nearest to the point of any of Sir Joseph Banks' Group, and had been seen from Stamford Hill. A boat was lowered down to sound about the ship, and I went on shore to take bearings of the different islands; but they proved to be so numerous, that the whole could not be completed before dark.
Sunday 7.I landed again in the morning with the botanical gentlemen, taking Arnold's watch and the necessary instruments for ascertaining the latitude and longitude. Twelve other isles of the group were counted, and three rocks above water; and it is possible that some others may exist to the eastward, beyond the boundary of my horizon, for it was not extensive. The largest island seen is four or five miles long, and is low and sandy, except at the north-east and south ends; it was called Reevesby Island, and names were applied in the chart to ​each of the other isles composing this group. The main coast extended northward from Point Bolingbroke, but the furthest part visible from the top of Kirkby Island was not more than four or five leagues distant; its bearing and those of the objects most important to the connection of the survey were these;

Granite forms the basis of Kirkby Island, as it does of the neighbouring parts of the continent before examined; and it is in the same manner covered with a stratum of calcareous rock. The island was destitute of wood, and almost of shrubs; and although there were marks of its having been frequented by geese, none of the birds were seen, nor any other species of animal except a few hair seals upon the shore. This description, unfavourable as it is, seemed applicable to all the group, with the exception of Reevesby and Spilsby Islands, which are higher and of greater extent, and probably somewhat more productive.
The latitude of the north side of Kirkby Island, observed from an artificial horizon, was 34° 33′ 1″ south, and longitude by time keepers, 136° 10′ 8″ east. The variation from azimuths taken on board the ship at anchor, with the head south-by-west (magnetic as usual), was 2° 40′ east; which corrected to the meridian, would be 2° 2′ east, the same nearly as was observed in Memory Cove, and at the entrance of Port Lincoln; but an amplitude taken on shore with the surveying theodolite, gave 3° 57′ east. This seemed extraordinary when, except at Point Donington, no local attraction of importance had been found in the shores of Port Lincoln, where the stone is the same. It was however corroborated by the bearings; for that of ​Stamford Hill, with 3° 57′ allowed, differed only 2′ from the back bearing with the allowance of 1° 39′; which is a nearer coincidence than I have generally been able to obtain.
At two in the afternoon the anchor was weighed, and leaving most of Sir Joseph Banks' Group to the right, we steered northward, following the direction of the main land. The coast is very low and commonly sandy, from Boston Bay to the furthest extreme seen from Kirkby Island; but a ridge of hills, commencing at North-side Hill in Port Lincoln, runs a few miles behind it. In latitude 34° 20′ this ridge approaches the water side, and in its course northward keeps nearly parallel, at the distance of two or three miles. It is moderately elevated, level, destitute of vegetation, and appeared to be granitic. At half past six, when we hauled off for the night, the shore was five or six miles distant; the furthest part bore N.N.E. ½ E., and a bluff inland mountain was set at N. 71° W., over the top of the front ridge.
The wind was moderate from the south-eastward; and at seven on the following morning,Monday 8. when the bluff inland mountain was bearing W. 2° N., we resumed our north-eastern course along the shore; which was distant seven miles, and had not changed its appearance. Towards noon the water shoaled to 6 fathoms, at three miles from a sandy beach; a lagoon was visible from the mast head, over the beach, and a small inlet, apparently connected with it, was perceived soon afterward. A few miles short of this, the ridge of hills turns suddenly from the shore, and sweeps round at the back of the lagoon, into which the waters running off the ridge appeared to be received. The corner hill, where the direction of the ridge is changed, was called Elbow Hill; and since losing sight of the bluff inland mount, it was the first distinguishable mark which had presented itself for the survey: it lies in latitude 33° 43′, and longitude 136° 42′. The coast there trends nearly east-by-north, and obliged us to haul close to the wind, in soundings of 7 to 9 fathoms.
We had then advanced more than twenty-five leagues to ​north-north-east, from Cape Catastrophe; but although nothing had been seen to destroy the hopes formed from the tides and direction of the coast near that cape, they were yet considerably damped by the want of boldness in the shores, and the shallowness of the water; neither of which seemed to belong to a channel capable of leading us into the Gulph of Carpentaria, nor yet to any very great distance inland.
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.before getting under way, and the situation of the anchorage was found to be in

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:

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 (Plate XVII. View 10.)given in the Atlas; 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.
Wednes. 10.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 extremity 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 straight a 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.
Thursday 11. Next morning we continued the examination upwards, carrying 4, 3, and 2 fathoms in mid-channel; but at ten o'clock our oars touched the mud on each side, and it was not possible to proceed further. I then landed and took observations in an artificial horizon for the time keeper, which gave 4′ 34″ of longitude to the west of the ship, or only two seconds more than was deduced from the bearings. Mount Brown bore S. 72° E., Mount Arden N. 26°E., and my last station on the eminence of red earth S. 6° E. The inlet wholly terminated at one mile and a half to the N. 16° W.
It seemed remarkable, and was very mortifying, to find the water at the head of the gulph as salt nearly as at the ship; nevertheless it was evident, that much fresh water was thrown into it in wet seasons, especially from the eastern mountains. The summits of the ridge lie from three to four leagues back from the water side, but the greater part of that space seemed to be low, marshy land. To the northward no hill was visible, and to the westward but one small elevation of flat-topped land; all else in those directions was mangroves and salt swamps, and they seemed to be very extensive.
​Two miles below the place where the observations for the time keeper were taken, was a small cliff of reddish clay on the western shore; and being near it on our return, when the sun was approaching the meridian, I landed to observe the latitude. It was 32° 27′ 56″ south; so that the termination of the gulph may be called in 32° 24½′ without making a greater error than half a mile. Mount Brown bore from thence S. 8o½° E., and its latitude will therefore be 32° 30¼′ south; the longitude deduced from bearings and the time keepers on board, is 138° 0¼′ east.
Our return to the ship was a good deal retarded by going after the black swans and ducks amongst the flats. The swans were all able to fly, and would not allow themselves to be approached; but some ducks of two or three different species were shot, and also several sea pies or red bills. Another set of bearings was taken on the western shore, and at ten in the evening we reached the ship, where Mr. Brown and his party had not been long arrived. The ascent to Mount Brown had proved to be very difficult, besides having to walk fifteen miles on a winding course, before reaching the foot; by perseverance, however, they gained the top at five on the first evening, but were reduced to passing the night without water; nor was any found until they had descended some distance on the following day. The view from the top of Mount Brown was very extensive, its elevation being not less than three thousand feet; but neither rivers nor lakes could be perceived, nor any thing of the sea to the south-eastward. In almost every direction the eye traversed over an uninterruptedly flat, woody country; the sole exceptions being the ridge of mountains extending north and south, and the water of the gulph to the south-westward.
Mr. Brown found the stone of this ridge of craggy mountains to be argillaceous, similar to that of the flat-topped land where I had taken bearings on the west side of the inlet. It is reddish, smooth, close-grained, and rather heavy. Bushes and some small trees grow in the hollows of the rising hills; and between their ​feet and the mangrove swamps near the water, there was some tolerably good, though shallow soil.
We had seen fires upon the eastern shore opposite to Point Lowly, on first entering the head of the gulph, and wherever I had landed there were traces of natives; Mr. Brown found them even to a considerable height up the side of the mountain; and it should therefore seem that the country here is as well inhabited as most parts of Terra Australis, but we had not the good fortune to meet with any of the people.
The observations taken by lieutenant Flinders fixed the position of the ship in latitude 32° 44′ 41″ south, and longitude by the time keepers 137° 49′ 56″ east. Twelve sets of distances of the sun and moon gave 137° 50′ 9″; but these being all on one side, the time keepers are preferred. Azimuths observed from the binnacle, when the ship's head was between S. by E. and S.S.E., gave 0° 43′ east, or 1° 37′ east, nearly, for the true variation; and there was no particular attraction upon the theodolite at any of my stations on shore.
We had two flood tides in the day setting past the ship, and they ran at the strongest one mile and a half per hour; the rise appeared to be from six to eight feet, and high water to take place at two hours and a half after the moon passed the meridian. Except in the time of high water, which is considerably later than at Thorny Passage, the tides at the head have a near affinity to those at the entrance of the gulph; whence the great differences at Port Lincoln, intermediately situate, become so much the more extraordinary.
Saturday 13.Nothing of particular interest having presented itself to detain us at the head of the gulph, we got under way in the morning of the 13th; having a light breeze from the north-westward. The western shore had been followed in going up, and for that reason I proposed to keep close to the east side in returning; but before eight o'clock, the water shoaled suddenly from 4 to 2 fathoms, and the ship hung upon a mud bank covered with grass, two or three miles from the shore. A kedge anchor was carried out astern; and in half ​an hour, we again made sail downward, in soundings from 5 to 10 fathoms, near the edge of the shoal.

The depth was then 7 fathoms; but there were banks a-head, extending to a great distance from the eastern shore, and in steering westward to pass round them, we had 3½ fathoms for the least water. It afterwards deepened to 7, and we again steered southward, but were not able to get near the land; on the contrary, the shallow water forced us further off as we proceeded. The wind was at west-south-west in the evening; and this not permitting us to lie along the edge of the bank, we came to an anchor in 7 fathoms, soft bottom; being then above four leagues from the eastern low shore, although there was only 3½ fathoms at less than a mile nearer in.

Sunday 14.In the morning we followed the line of the great eastern shoal, and its direction permitted us to approach nearer to the land, with soundings between 8 and 4 fathoms. A little before noon, after running half an hour in less than 4 fathoms and getting within about six miles of the land, we were obliged to tack and stretch off, the wind having veered to south-west. Our situation twenty minutes afterward, was in

We beat to windward all the afternoon, and at sunset anchored in 3½ fathoms, near the edge of the great bank and seven or eight miles from the land. The shore was low and sandy, but there was a ridge of hills behind it nearly similar to that on the west side of ​the gulph. Barn Hill lies at the back of this ridge and about twelve miles from the water; and towards the southern end of the ridge was another hill, also some distance inland, of which I shall have occasion to speak hereafter. A middle mount on the west side of the gulph, higher and further back than the one before set, was in sight from this anchorage; and the bearings taken were these:

Mount Brown was no longer visible; but it had been seen this afternoon at the distance of fifty-eight miles, and was sufficiently above the horizon to have been distinguished some miles further from a ship's deck in a perfectly clear day.
Monday 15.On the morning of the 15th, the wind had shifted to south-east; and the great bank then trending south-westward, we followed it with variable soundings between 3 and 10 fathoms. At ten o'clock the water had deepened to 15; and being then nearer to the west than to the east side of the gulph, and the wind having come more a-head, we tacked to the east-south-east; but in fifty minutes were obliged to steer westward again, having fallen into 3 fathoms on the edge of the bank. This is the narrowest part of the Gulph below Point Lowly, the two shores being scarcely more than twenty miles asunder; and of this space, the great eastern bank, if the part where we last had 3 fathoms be connected with it, occupies about eleven, and the shallow water of the west side one or two miles. The soundings we had in stretching westward across the deep channel, were, from the shoal 3, 5, 7, 10, 12, 12, 12, 10, 9, 8, 7, 6, 7, 6, 5 fathoms, at nearly equal distances asunder, and the last at six miles from the western land.
After sounding across the channel, we stood back, lying up south-east, and reached within five miles of the eastern shore, where the anchor was dropped in 4½ fathoms; Barn Hill bearing N. 69° E., and a cliffy projection, named Point Riley after the gentleman of that ​name in the Admiralty, S. 14° W., two or three leagues. This point was the furthest visible part of the eastern shore; and so low and uniform had the coast been from the head of the gulph, that this was the first mark I had found upon it for the survey. The great eastern bank, which we had already followed about sixty miles, seemed to terminate at Point Riley; and from thence southward, the gulph greatly enlarges its breadth. The situation of the point is about 33° 53′ south and 137° 30′ E.
Tuesday 16.We got under way at six in the morning, and the wind being from the south-eastward made a good stretch along the coast until noon. A patch of breakers then lay five miles to the south-east; but the land was ten miles distant, and some white sandy cliffs, four or five leagues from Point Riley, bore S. 52° E. The intermediate coast, as also that which extends several leagues to the north of the point, is low and sandy; but at a few miles back it rises to a level land of moderate elevation, and is not ill clothed with small trees. In the afternoon we had to beat against a southern wind; and the coast in that part being too open for anchorage, this was continued all night and the next morning;Wednes. 17. but with so little profit, that the same land was still in sight at noon, and our situation found to be as follows;

At six in the evening, the reddish cliffs were brought to bear N. 44° E., and a long point, or an island lying off a point, bore S. 43° W. two leagues. Our distance from a cliffy islet, close under the shore, was two or three miles, but the breakers from it were only half a mile off, and the depth was 4 fathoms.
Thursday 18. On the 18th in the morning, we fetched to windward of the island-like point, to which I gave the name of Point Pearce, in compliment to Mr. Pearce of the Admiralty. Its latitude is 34° 28½′ ​south, and longitude 137° 21′ east. On the south side of this point or island, for I could not fully ascertain its connexion, the shore falls back seven or eight miles to the east; and then trends southward. It is low and very sandy; but rises gradually to a level country, of the same description as that near Point Riley. At sunset, the land was seen as far as south-west-by-south; and the wind favouring us a little, we made a stretch for it. A fire upon the shore served as a mark to steer by; and on approaching it at ten o'clock, the anchor was let go in 6 fathoms, upon a bottom of coarse sand and small stones; the weather being fine, and wind moderate off the land.
The howling of dogs was heard during the night; and at daylightFriday 19. the shore was found to be distant two or three miles, and was woody, rising land, but not of much elevation. A remarkable point, which I named Corny Point, bearing S. 73° W. three miles, was the furthest land visible to the westward; its latitude, from meridian observations of Jupiter and the moon, is 34° 52′ south, and longitude from the time keepers 137° 6½′ east. Between this point and Point Pearce, twenty-eight miles to the north-north-east, is a large bay, well sheltered from all southern winds, and none others seem to blow with much strength here. The land trends eastward about seven leagues, from Corny Point to the head of the bay; but what the depth of water may be there, or whether any fresh stream fall into it, I am not able to state; the land, however, was better wooded, and had a more fertile appearance than any before seen in the neighbourhood. I called this Hardwicke Bay, in honour of the noble earl of that title.
Several observations for the variation of the compass had been taken whilst beating in the neighbourhood of Point Pearce. On its north side, eight miles from the shore, an amplitude with the ship's head S.W. by S. gave 4° 38′ east; at E. by N., when fourteen miles off, another gave 1° 13′ east; but azimuths three or four miles nearer in, 0° 10′ west; and at S.E., when six miles off, 0° 35′ west. On the south side of Point Pearce, the head being S.S.W., and the ​land distant thirteen miles, an amplitude gave 3° 15′ east. These different observations, which were all taken with the surveying compass, being corrected upon the principles and by the proportion explained in the Appendix No. II. to the second volume, will be respectively, 2° 51′, 4° 21′ furthest from the land, 2° 58′, 1° 41′ nearest the land, and 2° 1′ east. The mean is 2° 46′ east; which may be taken for the true variation at three or four leagues off Point Pearce in 1802; but close in with the shore, I suspect it was less by 1°, or perhaps 2°.
Having remained at anchor until the sun was high enough to admit of observations for the time keepers, we got under way at half past seven o'clock; and the coast round Corny Point being found to trend S. 27° W., nearly in the wind's eye, I stretched westward across the gulph towards Thistle's Island, in order to compare the time keepers with the longitudes of places before settled. Our latitude at noon, observed on both sides, was 34° 50′ 10″; Spilsby Island, the south-easternmost of Sir Joseph Banks' Group, was seen bearing N. 56° W., and the eastern bluff of Wedge Island, the central and largest of Gambier's Isles, bore S. 16½° W. Gambier's Isles, four in number besides two peaked rocks, had been first seen from the high land behind Memory Cove. They lie nearly in the centre of the entrance to the gulph; and the latitude of Wedge Island is 35° 11′ south, and longitude 136° 29′ east. Soon after four in the afternoon, I had the following bearings:

The longitude deduced from these bearings was 30′ 22″ east, from the head of Port Lincoln, and that resulting from observations for ​the time keepers taken in the same place, was 30′ 53″; showing a difference of no more than 0′ 31″ to the east, since quitting the port. This quantity in a sea observation is so small and uncertain, that I considered the time keepers to have gone correctly from March 4, when the last observations in Port Lincoln had been made, up to this time; and that the lunar observations taken in the interval might be reduced back to the head of the port by their means, and used to fix its longitude without any further correction.
Besides the bearings above given, there was a rocky islet four miles distant in the S. 78° W.; part of a ledge of low rocks which extended towards the north end of Thistle's Island, and may possibly be connected with the rock set from thence. This ledge is marked dangerous, in the particular chart.
Having satisfactorily ascertained the going of the time keepers, we tacked and stretched back for the coast on the east side of the gulph; but did not get sight of it before dark. At six on the following morning,Saturday 20.

An amplitude taken when the ship's head was south-by-east, gave variation 1° 25′ east, and azimuths at south-south-east, 1° 10′: the mean, reduced to the meridian, is 2° 13′ east, or a few minutes more than had been found on the west side of the gulph, and half a degree less than off Point Pearce.
The tide appeared to set us along the shore to the southward, although, from what was observed at Thistle's Island, it should have been the time of flood. With its assistance, and the wind having become less unfavourable, we were enabled to make a course for the furthest land. This proved to be a cape, composed of three cliffy points; near the northern part of which lay a cluster of black ​rocks. The southernmost cliff bore at noon E. 4½° S. six or seven miles, and beyond it there was no main coast visible; but three small islands, with several rocks and a reef, were seen to lie as far as five miles to the southward, out from the cape.
Although the continuation of the main coast was not to be distinguished beyond the cape, yet there was land in sight at the distance of seven or eight leagues, from about south to S. 18½° W. Whether this land were an island, or a part of the continent, and the wide opening to the eastward a strait, or a new inlet, was uncertain; but in either case, the investigation of the gulph was terminated; and in honour of the respectable nobleman who presided at the Board of Admiralty when the voyage was planned and ship put into commission, I named it Spencer's Gulph. The cliffy-pointed cape which forms the east side of the entrance, and lies in 35° 18′ south and 136° 55′ east, was named Cape Spencer; and the three isles lying off it, with their rocks, Althorpe Isles.
A line drawn from the nearest part of Cape Catastrophe to Cape Spencer will be forty-eight miles long, and so much is the entrance of the gulph in width. Gambier's Isles lie not far from the middle of the line; and if we measure upward from them, the gulph will be found, without regard to the small windings, to extend one hundred and eighty-five miles into the interior of the country. For the general exactness of its form in the chart, I can answer with tolerable confidence; having seen all that is laid down, and, as usual, taken every angle which enters into the construction. Throughout the whole extent of the shores the water line was almost every where distinguished; the only exceptions being, small portions at the head of Hardwicke and Louth Bays, of a bight near Point Lowly, and of the low land at the back of the great Eastern Shoal.
At noon, when off Cape Spencer, the wind became variable and light, with very hazy, cloudy weather; and the mercury in my marine barometer had fallen two tenths of an inch. At six in the evening a breeze sprung up at west-north-west; and as I expected a ​gale would come on, and that as usual it would veer to the south-west, we ceased to follow the coast beyond Cape Spencer, and steered for the land seen in the southern quarter. The Althorpe Isles were passed at eight o'clock, at the distance of eight or nine miles; and the wind being fresh at west, we made short trips during the night between the two lands, not knowing what might be in the space to leeward.Sunday 21. At daylight the ship was nearly in mid-channel, between the southern land and Cape Spencer, and nothing was seen to the eastward. It then blew a fresh gale at south-west, with much sea running; we stretched south-east under close-reefed topsails, to get under the lee of the southern land; and at eight o'clock, when the largest Althorpe Isle bore N. 33° W., it was distant six or seven miles to the south, and extended from S. 61° W. to 79° E., as far as the eye could reach. It was rather high, and cliffy; but there was nothing by which to judge of its connection with the main.
At ten o'clock we were close under the land; and finding the water tolerably smooth, had shortened sail with the intention of anchoring near a small, sandy beach; but the situation proving to be too much exposed, we steered eastward along the shore under two close-reefed top sails and fore sail, the wind blowing strong in squalls from the south-west. The furthest land seen a-head at noon, was a projecting point, lower than the other cliffs; it bore E. 7° S., four leagues, and lies in 35° 33′ south, and 137° 41′ east. It was named Point Marsden, in compliment to the second secretary of the Admiralty; and beyond it the coast was found to trend southward into a large bay containing three coves, any one of which promised good shelter from the gale. This was called Nepean Bay, in compliment to the first secretary (now sir Evan Nepean, Bart.), and we hauled up for it; but the strength of the wind was such, that a head land forming the east side of the bay was fetched with difficulty. At six in the evening we came to anchor in 9 fathoms, sandy bottom, within a mile of the shore; the east extreme bearing S. 76° E., and the land near Point Marsden, on the west side of Nepean Bay, ​N. 61° W., six leagues. A piece of high land, seemingly unconnected, bore from N. 45° to 78° E.; but no land could be distinguished to the northward.
Neither smokes, nor other marks of inhabitants had as yet been perceived upon the southern land, although we had passed along seventy miles of its coast. It was too late to go on shore this evening; but every glass in the ship was pointed there, to see what could be discovered. Several black lumps, like rocks, were pretended to have been seen in motion by some of the young gentlemen, which caused the force of their imaginations to be much admired; next morning,Monday 22. however, on going toward the shore, a number of dark-brown kanguroos were seen feeding upon a grass plat by the side of the wood; and our landing gave them no disturbance. I had with me a double-barrelled gun, fitted with a bayonet, and the gentlemen my companions had muskets. It would be difficult to guess how many kanguroos were seen; but I killed ten, and the rest of of the party made up the number to thirty-one, taken on board in the course of the day; the least of them weighing sixty-nine, and the largest one hundred and twenty-five pounds. These kanguroos had much resemblance to the large species found in the forest lands of New South Wales; except that their colour was darker, and they were not wholly destitute of fat.
After this butchery, for the poor animals suffered themselves to be shot in the eyes with small shot, and in some cases to be knocked on the head with sticks, I scrambled with difficulty through the brush wood, and over fallen trees, to reach the higher land with the surveying instruments; but the thickness and height of the wood prevented any thing else from being distinguished. There was little doubt, however, that this extensive piece of land was separated from the continent; for the extraordinary tameness of the kanguroos and the presence of seals upon the shore, concurred with the absence of all traces of men to show that it was not inhabited.
The whole ship's company was employed this afternoon, in ​skinning and cleaning the kangaroos; and a delightful regale they afforded, after four months privation from almost any fresh provisions. Half a hundred weight of heads, fore quarters, and tails were stewed down into soup for dinner on this and the succeeding days; and as much steaks given, moreover, to both officers and men, as they could consume by day and by night. In gratitude for so seasonable a supply, I named this southern land Kanguroo Island.
Tuesday 23.Next day was employed in shifting the top masts, on account of some rents found in the heels. The scientific gentlemen landed again to examine the natural productions of the island, and in the evening eleven more kanguroos were brought on board; but most of these were smaller, and seemed to be of a different species to those of the preceding day. Some of the party saw several large running birds, which, according to their description, seemed to have been the emu or cassowary.
Not being able to obtain a distinct view from any elevated situation, I took a set of angles from a small projection near the ship, named Kanguroo Head; but nothing could be seen to the north; and the sole bearing of importance, more than had been taken on board, was that of a high hill at the extremity of the apparently unconnected land to the eastward: it bore N. 39° 10′ E., and was named Mount Lofty. The nearest part of that land was a low point, bearing N. 60° E. nine or ten miles; but the land immediately at the back was high, and its northern and southern extremes were cliffy. (Atlas, Plate XVII. view 12.) I named it Cape Jervis, and it was afterwards sketched by Mr Westall.
All the cliffs of Kanguroo Island seen to the west of the anchorage, had the appearance of being calcareous, and the loose stones scattered over the surface of Kanguroo Head and the vicinity were of that substance; but the basis in this part seemed to be a brown slate, lying in strata nearly horizontal, and lamina of quartz were sometimes seen in the interstices. In some places the slate was split into ​pieces of a foot long, or more, like iron bars, and had a shining, ore-like appearance; and the strata were then further from the horizontal line than I observed them to be elsewhere.
A thick wood covered almost all that part of the island visible from the ship; but the trees in a vegetating state were not equal in size to the generality of those lying on the ground, nor to the dead trees standing upright. Those on the ground were so abundant, that in ascending the higher land, a considerable part of the walk was made upon them. They lay in all directions, and were nearly of the same size and in the same progress towards decay; from whence it would seem that they had not fallen from age, nor yet been thrown down in a gale of wind. Some general conflagration, and there were marks apparently of fire on many of them, is perhaps the sole cause which can be reasonably assigned; but whence came the woods on fire? That there were no inhabitants upon the island, and that the natives of the continent did not visit it, was demonstrated, if not by the want of all signs of such visit, yet by the tameness of the kanguroo, an animal which, on the continent, resembles the wild deer in timidity. Perhaps lightning might have been the cause, or possibly the friction of two dead trees in a strong wind; but it would be somewhat extraordinary that the same thing should have happened at Thistle's Island, Boston Island, and at this place, and apparently about the same time. Can this part of Terra Australis have been visited before, unknown to the world? The French navigator, La Pérouse, was ordered to explore it, but there seems little probability that he ever passed Torres' Strait.
Some judgment may be formed of the epoch when these conflagrations happened, from the magnitude of the growing trees; for they must have sprung up since that period. They were a species of eucalyptus, and being less than the fallen trees, had most probably not arrived at maturity; but the wood is hard and solid, and it may thence be supposed to grow slowly. With these considerations, I should be inclined to fix the period at not less than ten, nor more ​than twenty years before our arrival. This brings us back to La Pérouse. He was in Botany Bay in the beginning of 1788; and if he did pass through Torres' Strait, and come round to this coast, as was his intention, it would probably be about the middle or latter end of that year, or between thirteen and fourteen years before the Investigator. My opinion is not favourable to this conjecture; but I have furnished all the data to enable the reader to form his own judgment upon the cause which might have prostrated the woods of these islands.
The soil of that part of Kanguroo Island examined by us, was judged to be much superior to any before seen, either upon the south coast of the continent, or upon the islands near it; with the exception of some portions behind the harbours of King George's Sound. The depth of the soil was not particularly ascertained; but from the thickness of the wood it cannot be very shallow. Some sand is mixed with the vegetable earth, but not in any great proportion; and I thought the soil superior to some of the land cultivated at Port Jackson, and to much of that in our stony counties in England.
Never perhaps had the dominion possessed here by the kanguroo been invaded before this time. The seal shared with it upon the shores, but they seemed to dwell amicably together. It not unfrequently happened, that the report of a gun fired at a kanguroo near the beach, brought out two or three bellowing seals from under bushes considerably further from the water side. The seal, indeed, seemed to be much the most discerning animal of the two; for its actions bespoke a knowledge of our not being kanguroos, whereas the kanguroo not unfrequently appeared to consider us to be seals.
The latitude of the landing place near Kanguroo Head from an observation in the artificial horizon, was 35° 43′ 0″ south; and the longitude of our anchorage by time keepers, 137° 58′ 31″ east. This last, being deduced from observations only four days after the proof had of the time keepers having gone correctly since leaving Port Lincoln, should be as accurate, or very nearly so, as the longitude of that port.
​The variation observed from two compasses on board, with the head south-westward, was 6° 31′ east; but when the ship swung to a tide coming from east-north-east; the change in the bearings of different objects showed the variation to be about 4° less. The true variation I deduce to be 4° 13′ east; which is an increase upon what was observed on the west side of Cape Spencer, of 2°; although the distance be no more than twenty-four leagues, and the previous increase from Cape Catastrophe had been almost nothing. It seems probable that the existence of magnetic bodies in the land to the north-westward, and perhaps also in Kanguroo Island and Cape Jervis, was the cause of this change in the direction of the needle.
From appearances on the shore, I judged the rise of tide to be about six feet. The flood came from the east-north-east, twice in the day, and by the swinging of the ship, ceased at two hours and a half after the moon's passage; but the time of high water was afterwards found to be later by one hour and a half.
