The fires which had been lighted in the course of the day by the natives had rapidly spread over the summit of the hills, and at night the whole island was illuminated and presented a most grand and imposing appearance. After dusk Mr. Roe went with a party on sh.o.r.e in order to take turtle and at eight o"clock returned with one of the hawk"s-bill species (Testudo imbricata?) the meat of which weighed seventy-one pounds; about fifty eggs were also procured.
September 18.
The boat was sent again at four o"clock in the morning, as it was then high water, but returned at daylight without success.
Lacrosse Island, so named by Commodore Baudin, is about nine miles in circ.u.mference and about six hundred feet high; it is of a rugged character and intersected by numerous deep ravines and gullies; which, in the wet season, doubtless contain water.
The seaward or northern face of the island is formed of a fine-grained sandstone, dipping in strata, with a slight inclination to the South-East: large blocks of the same stone were also found scattered over the hills. The soil with which it is but slightly covered is little better than a thin layer of sandy earth; but notwithstanding its sterile quality it produces a variety of small plants, among which a shrubby acacia* was predominant and sufficiently abundant to tint the sides of the hills where it grew with the sea-green colour of its foliage. At last quarter ebb we got underweigh and proceeded to examine the opening by steering South-South-West towards the deepest part; at twenty-three miles from Lacrosse Island the gulf is divided by Adolphus Island into two arms; one of which trended to the South-South-East and the other to the South-South-West.**
(*Footnote. This plant is described in Mr. Cunningham"s Journal as Acacia leucophoea.)
(**Footnote. For the farther description of Cambridge Gulf see the Appendix A Part 4.)
As the western arm appeared to be of most importance we entered it and, with a strong flood tide, proceeded with great rapidity; as sunset approached we began to look for an anchorage, but found much difficulty on account of the strength of the tides, the great depth of water, and, as I at first thought, the unfavourable quality of the bottom: at last the anchor was dropped close to the south-west sh.o.r.e of Adolphus Island in the entrance of another arm which appeared to trend to the south-east under Mount Connexion. The noise made by the chain cable in running through the hawse-hole put to flight a prodigious number of bats that were roosting in the mangrove bushes; and which, flying over and about the cutter"s mast, quite darkened the air with their numbers.
September 19.
As I purposed remaining two days at this anchorage to examine the country we landed the next morning under View Hill, a high steep point on the south sh.o.r.e abreast of the anchorage; and, having climbed the summit by a rugged and fatiguing ascent, our labour was amply repaid by a very extensive view of the surrounding country and by obtaining bearings of Lacrosse Island and Shakspeare Hill; which served to fix the position of View Hill.
The south end of Adolphus Island, of which I had a commanding view, is a low, flat salt-swamp surrounded by mangrove bushes. To the south-eastward of Shakspeare Hill but quite detached from it is a range of hills extending in unconnected patches toward Mount Connexion. The princ.i.p.al stream of the gulf, which is the west arm, runs under the base of View Hill; three and a half miles farther on it opens into an extensive basin at the bottom of which is some high land; here the basin is contracted in its size, and trends to the westward round a mangrove point, where it was lost to view.
Mr. Cunningham had also made an excursion upon Adolphus Island; he had walked over the salt-swamp towards the hills, which, from his description, are precisely of the same character as View Hill; the rock formation is princ.i.p.ally of sandstone, blocks of which (the largest not exceeding three feet in diameter) are profusely scattered over the sandy soil and are sometimes found covered with a crust of quartz: but notwithstanding the aridity and apparent barrenness of the soil, many plants were recovering from the destructive effects of recent fires and springing up in great luxuriance. In our ascent we pa.s.sed through several deep gullies which bore the marks of having once yielded abundance of water but were now quite dried up.
September 20.
The next day Mr. Cunningham accompanied me on an excursion round Adolphus Island, taking from the anchorage an easterly direction; and pa.s.sing to the north of the two mangrove islands. On the eastern side of Adolphus Island we landed on one of two rocky islets, and took some bearings from its summit. It is composed of loose blocks of decomposed sandstone. On the summit we observed a large hawk"s nest but it was deserted by its constructor. The only plants that were found upon this rock were a p.r.i.c.kly capparis and a leafless ficus, the latter bearing cl.u.s.ters of small, whitish, globular fruit: these plants, with a small hibiscus, were the chief productions of the rock; and have probably been produced from seeds deposited there by birds.
On leaving these rocks I hoped to have reached in time some part of the north-east sh.o.r.e of Adolphus Island where I could observe the sun"s meridional alt.i.tude on the sea horizon; but we were detained in the arm by strong ripplings and a fresh sea-breeze until it was too late. Upon approaching the northernmost point of the island, which is low and covered with mangroves, we were obliged to pull round a bank that extends for some distance off it: as soon as this was effected the flood-tide commenced; we then landed under Adolphus Island just within the narrow entrance of the western arm; and whilst the people dined I was engaged in taking bearings and Mr. Cunningham ranged about in search of plants.
Everything wore the same arid appearance as those parts before visited; but the stems of some trees, of a larger growth than any we had yet seen on the hills, were found washed up on the beach. At five p.m. we returned on board; having made the circuit of Adolphus Island, a distance of twenty-five miles; without seeing the least vestige of man or animal or any appearance of fresh water.
September 22.
The wind and tide were unfavourable the next day for quitting our anchorage until the afternoon: in the morning Mr. Roe sounded and examined the south arm; and as he found the pa.s.sage to be quite clear we weighed at slack water with the intention of proceeding through it and anchoring in the basin; but the strength of the wind obliged us to anchor under View Hill and detained us the whole of the following day which was unsuccessfully spent in examining the gullies in search of fresh water: a hole was dug in one of the most favourable spots we could find; and at the depth of three or four feet the earth gradually became so moist as to flatter us with the hope that our labours would be rewarded by success: at three feet deeper water began to ooze through; but, upon tasting it, it turned out to be quite salt. Another place higher up was tried with the same result upon which further search was abandoned as useless.
In the evening we ascended a hill near the anchorage; whence a favourable view was obtained for the construction of my chart. The s.p.a.ce behind the beach to the foot of the hill is occupied by a level plain that has evidently been formed by the deposition of alluvial soil; over which, in many places, the last night"s high tide had pa.s.sed; but those parts which it had not reached were covered with a thin layer of salt which at a distance exactly resembled h.o.a.r-frost. Upon it was observed the track of a dog that had evidently been running towards the salt.w.a.ter pits to quench its thirst; and this, I fear, is only a proof of the total absence of fresh water, which, indeed, the desolate and burnt up appearance of everything around was sufficient of itself to bespeak. The country at the bottom of the gulf appeared to be of a rugged and mountainous character: the hills were observed in detached ranges to rise abruptly from a low level plain extending to the sh.o.r.e, the edge of which was lined as far as we could see by a belt of mangrove bushes. These plains were covered with salt incrustations over which were scattered the stems and branches of trees that had evidently been washed down from the hills and deposited there by inundations to which this country appears to be frequently subject. The trees appeared to be of so much larger size than any we have seen growing near the coast that we reasonably concluded the interior to be of a much more productive character than the country in the vicinity of the sea. Our means were however too confined to satisfy ourselves of this interesting fact.
September 23.
The following morning, the weather being more favourable, we left the bay and, with the remainder of the flood tide, beat through the narrows; in which, at one cast, we had no bottom at forty-five fathoms. As soon as we pa.s.sed this strait we entered the basin and a little before high water anch.o.r.ed in eight fathoms on its west side, where at noon, by a meridional observation to the south, the lat.i.tude was found to be 15 degrees 21 minutes 53 seconds South. After this we landed in the vicinity of our station; but, finding the country as barren and dreary as before, the evening was spent in sounding between the cutter and the western sh.o.r.e.
September 24.
The next morning we reached the farther end of the basin and anch.o.r.ed under a remarkable range of hills; which, from their appearance, were called the Bastion Hills; the lat.i.tude of this station is 15 degrees 29 minutes 38 seconds South. The gulf, which had now a.s.sumed the character of a river, trended to the South-West, and at the distance of three or four miles disappeared among some high land in that direction.
In the evening (since we had lately seen no appearance of sharks) the people were allowed to bathe; but they had no sooner finished, and everyone on board, than an alligator swam past the vessel. The appearance of this animal revived some hopes of our yet finding fresh water and also that the gulf would terminate in a river; the breadth here is about a mile and a half and the rise of the tide about twenty-one feet: the ebb set at the rate of three knots per hour and the water was very muddy; but at low tide, upon being tasted, it still retained its saltness.
September 25.
At daylight the next morning we were again under weigh; but, the wind being directly adverse, were obliged to make several tacks: as we proceeded the opening was found to get more contracted and to wind through a very narrow strait between high precipitous hills; and as, on approaching it, the pa.s.sage appeared too narrow to be attempted with safety, we anch.o.r.ed at about two miles from it near the low west bank; and after breakfast Mr. Cunningham accompanied me in the whale-boat to continue its further exploration.
The wind was blowing a fresh gale from the South-West directly out of the Gut and impeded us a good deal; but the tide was running with such strength that we were not long before we pa.s.sed through. This pa.s.sage is about two miles and a half long, bounded on either side by rocky barren hills rising abruptly from the water. The channel is deep for our boat"s lead-line of twenty fathoms did not reach the bottom. At the south end of the gut the land opened out into another basin which, like the former, is surrounded by low land overrun with mangroves and studded with several islets, occasionally covered by the tide. The course of the river still trended to the south-west, in which direction we continued to pull but found some difficulty from its being very shoal; for in the fair way across there was not more water than eighteen feet at three-quarters"
flood. At eleven o"clock, having crossed the basin, we landed on an islet which, like the rest, had been covered by the last high tide. The river had now contracted to the width of one hundred to one hundred and fifty yards and trended by a winding course to the south and south-east, but the water was still as salt as ever although we were at least sixty miles from the sea. As there was now no probability of our extending the examination of this river for any useful purpose we stopped at high water and landed on the bank to examine the country whilst the people dined. We were about two or three miles from the base of a most remarkable quadrangular-shaped ma.s.s of hills rising abruptly from an extensive flat plain covered with salt: the sides sloped down with a very steep descent to the base and the top of the range was circ.u.mvented with cliffs which, protruding at intervals, so perfectly resembled the bastions and ramparts of a formidable fortress that it wanted only the display of a standard to render the illusion complete. It was named Mount c.o.c.kburn in compliment to Vice-Admiral Sir George c.o.c.kburn, G.C.B., one of the Lord Commissioners of the Admiralty. The accompanying drawing of this remarkable range of hills was taken from the west point of the south entrance of the gut.
All around us bore the most desolate appearance. The gra.s.s, which was quite dry, wanted but a spark and a breeze to set the whole country in flames. The soil on which it grows, which is about two feet above the high watermark, is a stiff clay; covered with a slight incrustation of salt on which the tracks of native dogs were noticed; several smokes were observed at a distance but no natives were seen. The tide had now began to ebb; and as there was no inducement to detain us for the next day to examine it farther we set off on our return; and on our way landed for bearings on the small islet in the middle of the Inner Basin. We also went on sh.o.r.e in two places on the west bank within the Gut; at the first we found the marks of an encampment of a tribe of natives: eight or nine spots of circular form were cleared away amongst the gra.s.s and in the centre of each were the ashes of a small fire, close to which we noticed some large flattened stones with a smaller one lying upon them, which the natives probably use for the purpose of bruising or grinding the seeds of plants and breaking sh.e.l.lfish. The impressions of dogs" feet were observed about the fireplaces, as well as the recent tracks of kangaroos.
The only animal that we saw during our excursion was a small kangaroo-rat; it was skipping about the rocks near the sea. A ravine, of appearance the most favourable for our search for water, was selected from a great many as most likely to afford it; and we landed for that purpose; but we met with our usual bad success; torrents had once poured down it, the effects of which alone were left. Recent traces of kangaroos were again seen here: these animals can require but little drink unless the dew that is nightly deposited is sufficient for the purpose of quenching their thirst, for we did not see a drop of fresh water in any part we landed at.
We reached the vessel a short time before sunset and terminated the examination of this gulf, which at one time bore so flattering an appearance as to leave little doubt of our being able to complete our water, and that even with facility. I felt so much disappointed that two or three small openings, which probably served but to drain the vast plains of inundated country that environ the hills on the sh.o.r.es of this gulf, were pa.s.sed by unheeded; among which was the extensive branch that trended to the south-east under Mount Connexion; this opening appeared to possess a similar character with that we had just been employed in exploring.
September 25 to 26.
On the 26th we got under weigh to return; but, having to work against a contrary breeze, made no farther progress than the anchorage occupied on the 23rd. The smokes of many fires were seen during the day; but in this country where everything is so parched and dry a fire will lie dormant a considerable time, and as the breeze springs up the flames will kindle and run along in the direction of the wind for many miles.
September 27.
The next day at half-past twelve o"clock when the ebb tide began to make, the wind freshened up from South-East and soon carried us into the narrows: it then veered round to the eastward, and after half an hour"s calm a strong sea-breeze set in against us; but the tide being in our favour we made quick progress until half an hour before the time of low water, when we anch.o.r.ed under the north-west end of Adolphus Island.
I have this day to record the death of one of the crew, William Nicholls, who, for some time past, and particularly during the last three days, had been suffering from a dropsical complaint; his death was occasioned by suffocation, having very imprudently laid down with his head to leeward while we were under sail: this poor fellow had been for nearly three months on our sick list; he was a native of Norfolk Island, and, when in health, had been one of my most useful and attentive men.
September 28.
He was interred the next morning on sh.o.r.e; in memorial whereof the north-west point of the island was named after him. Soon after noon the ebb tide made, and we worked out against a strong northerly breeze, which gave us a good opportunity of ascertaining the soundings and breadth of the channel. The tide however did not serve to carry us out of the gulf, and at low water we dropped the anchor near a bank on the western side in six fathoms, sandy bottom, out of the influence of the tide; which in the mid-channel was observed to run with great strength.
After sunset the clouds began to collect in the South-East and threatened the approach of bad weather; but in our situation the anchor, although we had but one, was our best security.
September 29.
At two o"clock in the morning heavy clouds rose in the East-South-East and the wind freshened from that direction; it however soon after veered back to South-East and enabled us to weigh. The weather was cloudy and dark, but as the plan of the gulf had been already roughly formed, and our soundings laid down, I was sufficiently aware of the course we had to steer. The only event to be dreaded was that, in getting under weigh, the cutter might cast with her head insh.o.r.e, when we should certainly have been thrown upon the bank; our fears however upon this point were happily groundless, and our course being unimpeded, we made quick way towards Lacrosse Island, which was pa.s.sed at daylight.
Having now cleared this extraordinary inlet which was named Cambridge Gulf in honour of His Royal Highness the Viceroy of Hanover, we bore up along sh.o.r.e to the westward, sufficiently near to it to have perceived any opening that might exist, and to make such remarks as were necessary for its delineation. At sunset we were off Cape St. Lambert of the French and their Mount Casuarina was also seen. M. de Freycinet"s description of the hill is very correct, but at the distance which we were it was only visible when it bore between South and West-South-West; for the land in that bearing intervened and concealed it. Large fires were burning three or four miles inland.
September 30.
At sunset we hauled off sh.o.r.e for the night; and the next morning saw Mount Casuarina again bearing south; its lat.i.tude was found to be 14 degrees 23 minutes 15 seconds, and its longitude 127 degrees 36 minutes 50 seconds East of Greenwich, which is 3 minutes 10 seconds to the westward of the situation that the French have a.s.signed to it.
Hence the sh.o.r.e takes a north-westerly trend. At noon we were two miles and a half from Cape Rulhieres when our lat.i.tude was 13 degrees 51 minutes 58 seconds; at seven miles in a North 37 degrees West direction from the cape, which is a stony point, is Captain Baudin"s Lesueur Island, a low flat sandy island. We pa.s.sed between it and the main, and had soundings with fifteen fathoms.
In pa.s.sing a projection of land which appeared to be an island and off which is a considerable reef, the bottom shoaled to eight fathoms but as quickly deepened again to no bottom with fifteen fathoms. This probable island may perhaps be the second Lesueur Island, which is laid down upon the French chart; but I have doubts of it; for I do not think it could be distinguished as an island at the distance Captain Baudin was from the sh.o.r.e. The land now extended towards a point which was called Cape Londonderry, whence it took a westerly direction. On arriving up with the reef which extends off Cape Londonderry we hauled off to the northward and pa.s.sed the ensuing night under easy sail, during which our soundings were between forty and forty-six fathoms. A very large natives" fire was burning about two or three miles inland, but the Indians did not show themselves. Last night our people caught a porpoise, which helped to diminish the bad effect of salt provisions.
We were now very weak-handed; three men, besides Mr. Bedwell who was still an invalid, being ill, considerably reduced our strength; insomuch that being underweigh night and day, with only one spare man on the watch to relieve the masthead look-out, the lead, and the helm, there was great reason to fear the fatigue would very much increase the number of complaints. Since leaving Port Jackson we had never been free from sickness, but it was confined princ.i.p.ally to two or three individuals who were not able to endure the very great heat. Upon the whole we thought ourselves very fortunate that, considering the frequency of illness on board and the violence of the diseases by which some of our people had been attacked, particularly in the cases of Mr. Bedwell and Mr.
Cunningham, we had only lost one man; and this from a complaint which even medical a.s.sistance might not, perhaps, have cured; and by an accident which could not have been prevented, for our people were at the moment so busily employed in working the vessel through a dangerous navigation that the unfortunate man"s situation was not known until the vital spark was nearly extinct, and too far gone for any human means to save his life. The thermometer now ranged between 80 and 87 degrees in the shade; and the fast approach of the sun (the declination of which was 3 degrees South) was daily felt.
