Chapter VIII (2)
After clearing Blue-mud Bay, we worked to the north-eastward; and at eight in the evening, anchored under Nicol's Island in 5½ fathoms, muddy bottom, one mile from the shore, and two and a half from the low eastern point of Isle Woodah: two large rocks and much shoal water lie between the islands, and prevented me from seeking shelter there. In the morning [WEDNESDAY 26 JANUARY 1803] we stretched N. N. E., for the projecting part of the main land before set at N. 55° 20' E. from the eastern hummock of Morgan's Island; and to which I have given the name of CAPE SHIELD, in compliment to captain W. Shield, a commissioner of the navy. There is a small bay on its south-west side, and we anchored there in 4 fathoms, blue mud, with the outer points of the bay bearing S. 41° E. and N. 21° W., each distant one mile.
On landing with the botanists, I found the beach convenient for hauling the seine, and ordered one to be sent from the ship, which had tolerable success. The cape is low land, mostly covered with wood; and a sandy hillock, perceived from the mast head about one mile behind the beach, being the sole place whence a view was likely to be obtained, I went there with a theodolite. No part of the main coast to the eastward could be seen from thence beyond a low projection distant seven or eight miles, which I named _Point Arrowsmith_; to the west my view was obstructed by trees, but some points before set were visible, and more to the southward; and the following, amongst many useful bearings, were taken.
Chasm I., centre of the highest part, S. 33° 15' E. Wedge Rock, centre, S. 5 55 W. Nicol's I., south-east point (over the south extreme of C. Shield, dist. 1½ miles), S. 26 30 W. Round-hill Island, the top, S. 89 25 W. Point Arrowsmith, N. 62 20 E.
The sand hill whence these bearings were taken, stands close to the water on the east side of Cape Shield; and directly off it, at a mile and a half distance, lies a small island: upon the shore was found a carling of a ships deck, of teak wood, in a decayed state. On the land side of the hill was a small lake of fresh water, frequented by ducks, teal, and smaller aquatic birds, several of which were shot.
Cape Shield lies in latitude 13° 19¾' south, longitude by the survey 136° 23' east; it projects out six miles from the body of the land, and appears, when seen from the south, to be an island. Two cassowaries were seen upon it, and many tracks of men, dogs, and kangaroos. The wood is small, and the soil sandy; but the botanists made an ample collection of plants, some few of which made an addition to their former discoveries.
THURSDAY 27 JANUARY 1803
Next morning we steered westward, with a fair wind, to explore the main coast up to Mount Grindall, and see the northern part of Blue-mud Bay. At three leagues from Cape Shield, we passed a projecting point to which I gave the name of _Point Blane_, in compliment to Dr. (now Sir Gilbert) Blane, of the naval medical board. Five miles from it to the W. S. W., lies Round-hill Island, and after passing between them with 4 fathoms water, I sent the boat to sound between the island and Mount Grindall, purposing to anchor there; but the depth was too little for the ship. We then worked up to a large bight on the west side of Point Blane; and the water being shallow towards the head, anchored in 3 fathoms, muddy ground, with the extremity of the point bearing S. 41° E. two and a half miles.
An officer was sent on shore to search for fresh water and examine the beach with a view to hauling the seine, but had no success; the naturalist accompanied him, to botanise, and not coming down to the boat at dusk, the officer left a man with a fire on the beach, to wait his arrival. At ten o'clock a gun was fired, and the boat sent back; but nothing had been heard of the naturalist, or the seaman who carried his specimen boxes, and some apprehensions began to be entertained. Soon after daylight [FRIDAY 28 JANUARY 1803] we had the satisfaction to see Mr. Brown on the shore. It appeared that from one of those mistakes which so frequently occur in thick woods and dull weather, when without a compass, the east had been mistaken for west; and Mr. Brown reached the water side at dusk, but on the wrong side of the point. He thought it more prudent to remain there all night, than to re-enter the wood in the dark; and the report of the gun having given him the true direction, he had no difficulty in the morning. No natives were seen; but the howling of dogs was heard not far off.
Whilst the botanists continued to follow their pursuits upon Point Blane, I went over in the whale-boat to Mount Grindall, with the landscape painter; from whence, after cutting down some small trees at the top, my view extended over all the neighbouring islands, points, and bays. Blue-mud Bay was seen to reach further north than Mount Grindall, making it to be upon a long point, which I also named _Point Grindall_, from respect to the present vice-admiral of that name; further west, in the bay, was a stream running five or six miles into the land, terminating in a swamp, and with shoal banks and a low island at the entrance; all the northern part of the bay, indeed, seemed to be shallow, and to have no ship passage into it on the north side of Isle Woodah. The large bight between Points Grindall and Blane extended two leagues above the ship, but it did not appear to receive any stream of water; a still larger bight, between Point Blane and Cape Shield was also visible, though not so distinct as to speak of it particularly: the extremity of the cape bore S. 76° 15' E. An observation to the north and south, taken on the outermost rocks, places Mount Grindall in 13° 15½' south; and the longitude from survey is 136° 6 1/3' east. Mr. Westall's sketch in the Atlas, taken from the ship at anchor under Point Blane, will show the appearance of this mount and of the neighbouring land. (Atlas, Plate XVIII. View 13.)
The top of Mount Grindall consists of the same kind of sand stone, with particles of quartz in it, as seen at Groote Eylandt; but the rocks on the shore are granite, and one block made a brilliant appearance from the quantity of mica it contained. There is very little soil on the surrounding land, the surface being either sandy or stony; it was however mostly covered with grass and wood, and amongst the trees was a cluster of the new species of _eugenia_, from which the boat's crew filled their handkerchiefs with fruit, which they called apples. Two natives were distinguished upon Round-hill Island; but none at Point Grindall, nor any thing to show that they had been there recently: the foot-marks of dogs and kangaroos were both recent and numerous.
Strong squalls from the eastward, with rain, much impeded our return to the ship in the evening; and from a continuance of the same unfavourable weather, Point Blane could not be repassed until the afternoon of the 30th [SUNDAY 30 JANUARY 1803]. The wind was then S. E., and we worked to windward all night, between the main coast and Isle Woodah; and not being able to weather Cape Shield on the following day [MONDAY 31 JANUARY 1803], we ran to our former anchorage under it, and remained there for the night.
TUESDAY 1 FEBRUARY 1803
Next morning we stood out of the bay with light winds; and after being put into some danger by them, in passing the island near Cape Shield, a breeze sprung up at W. by S. and we proceeded in the examination of the main coast. The situation of the ship at noon, and the bearings of the land were as under:
Latitude, observed to the north and south, 13° 20' 16" Chasm I., centre of the high part, S. 16 E. Cape Shield, the south extremity, N. 86 W. Point Arrowsmith, dist. 6 miles, N. 18 W. Furthest extreme visible from the deck. N. 10 E.
Our course was then directed N. E. by N., parallel with the coast, until the wind veered round ahead and drove us off to the eastward; at six o'clock Point Arrowsmith bore W. 2° S., ten or eleven miles, and a round hummock, beyond the noon's extreme, was then seen at N. 2½° E. The coast here shows some projections on which are sandy hills, with shallow bights between them; the hills further back, especially behind Point Arrowsmith, are better covered with wood, but there was no appearance of fertility in the country, nor of shelter in the bights.
[NORTH COAST. CALEDON BAY.]
We worked to windward all night, with a north-western breeze; and in the morning [WEDNESDAY 2 FEBRUARY 1803] saw two islands, the outermost rather low and flat, nearly in the situation where three are marked in the Dutch chart. These are laid down at the entrance of an opening, of a river-like form; and there appeared to be a wide opening behind them, the entrance being round a projection upon which is the hummock set at N. 2½° E. in the evening: this projection I have named CAPE GREY, in compliment to the Hon. general Grey, lately commander of the forces at the Cape of Good Hope. Our situation and bearings at noon were,
Latitude. observed to the north and south. 13° 3' 41" Longitude from survey, 136 46½ Furthest southern extreme, from the deck, S. 73 W. Cape Grey, the round hummock, N. 56 W. Cape Grey, outermost rocks near it, N. 41 W. Outer and rather flat isle, centre, N. 3 W.
On the wind veering to north-east, we were enabled to weather the rocks near Cape Grey, but not more than a quarter of a mile; the depth in passing was 9 fathoms, and it continued between that and 11, two miles further up the bay, where, on its falling calm, an anchor was dropped. In the evening we ran further up, and at sunset anchored in 9 fathoms, mud and sand, near the innermost and largest of three islands which lie in the entrance. Around, and between these islands, were many islets and rocks, and others were seen to the north-eastward; the bay extended to the north-west, and was divided into two branches by a projection named _Point Middle_, the eastern branch being defended from the sea by a tongue of land, whose south point seemed to be connected by a reef of rocks with the inner island. This point I have called _Point Alexander_; and to a hill upon the furthest visible part of the coast to the northward, the appellation of _Mount Alexander_ is given.
THURSDAY 3 FEBRUARY 1803
In the morning, there being no wind to move the ship, I sent the master up the bay with the whale boat, to search for fresh water and a secure anchorage; and on his making the signal to follow, a little before noon, we steered for Point Middle. A shoal was seen to extend from it, down the bay; and the depth having diminished to 4 fathoms, we hauled up into the eastern branch, and anchored under Point Alexander in 4½ fathoms, muddy bottom; our distance from the shore being one mile, and two cables length from a bank in front of it, upon which there was only six feet water. In this situation, the outer rocks near Cape Grey bore S 28° E., and the inner rocks from the island near Point Alexander., S. 35° E.; the intermediate angle of 7° being that at which alone we were open to the sea. Several natives were seen on the shore abreast of the ship, and lieutenant Fowler was sent to communicate with them, and to search for fresh water. They stayed to receive him, without showing that timidity so usual with the Australians; and after a friendly intercourse in which mutual presents were made, Mr. Fowler returned with the information that fresh water was plentiful.
FRIDAY 4 FEBRUARY 1803
Early next morning, having given directions for two tents, a seine, and a corporal's guard, to be sent on shore under the command of the first lieutenant, I landed with the botanical gentlemen; the natives running from their night residences to meet us. There were twelve middle-aged and young men, all of whom expressed much joy, especially at seeing _Bongaree_, our good-natured Indian from Port Jackson. On the arrival of two other boats, the natives retreated into the wood, except two, who assisted in hauling the seine; and the others came back by degrees, without arms as before, and received a portion of the fish. A situation was chosen for the tents, and confidence seeming to be established, I went into the wood, towards some sand hills, for the purpose of taking bearings; but whilst making the circuit of a salt swamp which lay in the way, the natives were heard running in the wood, and calling to each other. This happened twice, and at length a musket was fired; upon which I returned to the tents with all expedition.
When the botanical gentlemen had entered the wood with their attendants, the greater part of the natives followed them; and one took an opportunity of snatching a hatchet from the hand of a servant. The Indians then ran off, but seeing no pursuit, nor much notice taken, soon returned, and became more friendly than ever. Each of our party had a native with him, walking arm in arm, and Mr. Brown's servant had two, who paid him particular attention; so much so, that whilst one held him by the arm, the other snatched the musket off his shoulder, and they all again ran off; that is, all who remained, for several had previously withdrawn themselves. A musket was fired after the thief; but he had already got some distance, and it produced no other visible effect than that of making him run faster. The botanists then judged it imprudent to follow their pursuit, and returned to the tents.
Two hours passed before any thing more was heard of the natives; some were then seen in the wood, and an interview was obtained with two, who being made to understand that a hatchet would be given on the musket being returned, they went off to fetch it. In a little time it was actually brought, with the stock broken and ramrod gone, and the hatchet was paid; after which the natives came to the tents with confidence, and some would have remained all night, had they been permitted.
SATURDAY 5 FEBRUARY 1803
This afternoon and the following morning, I took bearings from two stations on Point Middle, and others from a sandy hummock on Point Alexander. The natives came early to the tents, and behaved themselves tranquilly until noon; when one of those who had been most kindly treated, ran off with a wooding axe, and from the thickness of the forest, eluded the pursuit made after him. The corporal and another marine, who had run after the Indian without their hats, received a _coup-de-soleil_, and were sent on board in a state nearly approaching to delirium; but they happily recovered.
Finding these people so determinately bent upon stealing every thing within their reach, I ordered lieutenant Fowler to watch an opportunity of seizing two of them; and after a while to release one, making him understand that the other would be carried away in the ship, if the stolen axe were not returned. In the evening, I went over with two of the gentlemen to the south side of the bay; for the purpose of taking a station upon a hill there named _Mount Caledon_, whose height exceeded that of any other near the water side.
We landed at dusk, at the foot of the mount; and ascended the top next morning [SUNDAY 6 FEBRUARY 1803] before the heat of the sun became excessive, passing in the way several streamlets which were coursing rapidly down to the sea. The view was fully equal to what had been anticipated, and extended to a projection half way to Point Arrowsmith on one side, and over all the islands in the entrance to Mount Alexander on the other. Out of thirty-nine bearings taken at this station, the following are selected as being most essential to the survey of the coast.
The tents, N. 2 ° 50' E. Point Alexander, the extremity, N. 60 0 E. Outer, and rather flat isle, N. 86° 15' to 88 22 E. Mount Alexander, the top N. 37 30 E. Cape Grey, the outer rocks near it, S. 65 5 E. A southern projection of the coast, S. 14 8 E.
We returned to the ship in the afternoon, and the natives had not then approached the tents since the theft of the axe; but next morning [MONDAY 7 FEBRUARY 1803] two of them advanced, bringing some small fruits; and on being invited to eat fish, they sat down and were immediately seized, some others who followed, running away on hearing their cries. In a little time the eldest and most intelligent of them was liberated; on his promising by signs to restore the axe, and being made to understand that his companion would be carried off, should he fail. We observed from the ship much running of the natives amongst the bushes, and peeping about the tents; and least they should attempt any mischief, a spring was put upon the cable, and a six-pounder, with grape shot, kept ready; but after one of the prisoners was released they seemed to have less anxiety, and several swam back across a salt creek, to their usual place of residence.
In the evening I landed at the tents; and taking the native, a youth of fourteen named _Woga_, into the boat, rowed to the place most frequented by the Indians, many of whom were seen behind the bushes. Two came forward, bringing a young girl in their arms; and by expressive signs they offered her to Bongaree, in order to entice him on shore, for the purpose, apparently, of seizing him by way of retaliation. We demanded the restoration of the axe, and our prisoner seemed to use all his powers to enforce it; but the constant answer was, that the thief _Yehangeree_, had been beaten and was gone away; and finding no axe likely to be brought, Woga was carried on board the ship, through a great deal of crying, entreating, threatening, and struggling on his part. He there ate heartily, laughed, sometimes cried, and noticed every thing; frequently expressing admiration at what he saw, and especially at the sheep, hogs, and cats. We had not seen any bows and arrows in the Gulph of Carpentaria, nor in any part of Terra Australis; but some of those from Murray's Islands being shown to Woga, he knew the use of them, and gave their names in his language; it may therefore be true, as Burgomaster Witsen relates, that they are used by the natives on the North-west Coast and in the Gulph; but when he describes the bows as being "of such a length, that one end rests on the ground when shooting," I cannot help suspecting some exaggeration in his informer.
TUESDAY 8 FEBRUARY 1803
After breakfast next morning, I took our prisoner to the tents. On approaching the shore, he was preparing to make a spring out of the boat, which made it necessary to bind him again, for he had been loosed on board the ship. He struggled much, calling upon Bongaree to assist him; but after a while, became quiet, and I left him bound to a tree, eating rice and fish.
A party of the gentlemen landed near the head of the bay, hoping to botanize without interruption; but a number of natives had collected there, two of whom advanced, and sought to entice them into the wood by explaining how many animals might be there shot. The gentlemen were aware of the treachery, and soon thought it advisable to return to the boat; upon which the natives closed in upon them, with poised spears and every appearance of intended mischief. The pointing of muskets stopped their forwardness for a moment; but they came on again, and a shot was fired at each of the two foremost, which put them to flight, and they were not seen afterwards; but the gentlemen thought it unsafe to proceed in their occupation, and returned to the ship. Neither of the two natives dropped; but the muskets being loaded with buck shot, it was supposed that one or both, must have been wounded.
The second evening of Woga's captivity came, and there was no appearance of the axe being restored; his detention, on the contrary, had caused some annoyance to us, and mischief to his countrymen; and if persevered in to the extent of carrying him away, might be an injury to those who should come after us, especially to captain Baudin, whom we daily expected to meet, according to what he had said at Port Jackson. Had the consequences affected ourselves alone, the time of our departure was so near that I should have been glad to have kept Woga; for he was a sprightly lad, whom our treatment would soon have reconciled, and in any future intercourse with his countrymen, as also in furnishing information upon many interesting points, he might have been of service; but for the above reason, and that it was not altogether just to do otherwise, I determined to release the poor prisoner though the axe should not be restored, and went to the tents for that purpose. Woga appeared to be a little melancholy in his bondage, but upon the whole, had not fared amiss, having been eating the greater part of the morning and afternoon. He begged hard to be released, promising, with tears in his eyes, to bring back the axe; and after giving him some clothing and presents, he was suffered to depart. As far as two hundred yards, he walked away leisurely; but then, looking firs behind him, took to his heels with all his might, leaving us no faith in the fulfilment of his pathetic promises.
At this time the holds were completed with water and wood, and on the following morning [WEDNESDAY 9 FEBRUARY 1803] the last observations for the time keepers were taken; after which the shore establishment was embarked, and we prepared for sea. The botanists made an excursion upon Point Middle, and pursued their researches without disturbance; and neither Woga nor any of his countrymen were seen during the whole day.
It has been said, that an opening of a river-like form is laid down in the Dutch chart, in the situation of this bay. No name is there given to it; and as I conceive our examination to confer the right of bestowing one, I have distinguished it by the title of CALEDON BAY, as a mark of respect to the worthy nobleman, lately governor of the Cape of Good Hope, after whom the mount on the south side was also named.
There is no other safe passage into the bay than that between the islands in the entrance and Cape Grey; which cape is remarkable for the round hummock on its extremity, and lies in latitude 13° 1' south, and longitude 136° 42' east. The western branch of the bay appeared to be shallow, and not well sheltered, so that I did not go up it to sound; but in the eastern branch, which is near three miles wide, there is from 4 to 3 fathoms on blue mud, up to within three-quarters of a mile of a rocky point at the head; and the rocks of Point Alexander may there be nearly, if not altogether brought to shut on with those of Cape Grey. Wood for fuel was plentiful every where, and there was no difficulty in procuring water from the ponds and holes in the low, sandy land near the shore of Point Alexander; but from May to December, I doubt whether they would not all be dried up, as well as the small streams which descended from Mount Caledon. Our success with the seine was very moderate, more sea slugs, or what we called sea cucumbers from their shape, being brought on shore than fish; these differed from what we had seen on the reefs of the East Coast, in being of a more firm consistence, and of a light brown or grey, instead of a black colour: when these slugs were pressed with the foot, they threw out a stream of water to some distance.
The country round Caledon Bay, especially at the heads of the two branches, is generally low land; Mount Caledon and the hills of the south side are of granite, and this stone is found in some other parts; but at Point Alexander the basis is a sand stone, more or less impregnated with iron, and at Point Middle it is almost iron ore. A piece of this last stone carried the needle of the theodolite entirely round; yet the bearings taken from thence did not show any difference from those at Mount Caledon, and from those upon Point Alexander, taken from a hillock of sea sand, they did not differ more than half a degree.
So far as our examination went the soil is poor, being either sandy or stony, with a small mixture in some places of vegetable earth; notwithstanding which both the grass and wood were luxuriant, owing to the abundance of rain which had lately fallen, and to the warmth of the climate: in the dry season, I should judge the country would be almost burnt up. The _casuarina_ was plentiful in the sandy places, and the _eucalyptus_ amongst the rocks, where it reached a tolerable size; the wild nutmeg was found upon Point Middle, and there alone; our apple, the new species of _eugenia_, grew on Point Alexander and elsewhere, and also a few other plants bearing small fruits of little use. Foot marks of the kangaroo were seen in different places, but none of the animals, nor indeed any quadruped; and birds seemed to be rare, both in the woods and on the shores.
The natives of Caledon Bay are the same race of men as those of Port Jackson and King George's Sound, places at nearly the two opposite extremities of Terra Australis;* in personal appearance they were behind some tribes we had seen, but the difference did not go beyond what a less abundant supply of food might produce. All those who came to the tents had lost the upper front tooth on the left side, whereas at Port Jackson it is the right tooth which is knocked out at the age of puberty; whether the women undergo the same operation, contrary to the usage at Port Jackson, we had no opportunity of knowing, having seen only one female, and that at a distance. This girl wore a small piece of bark, in guise of a fig leaf, which was the sole approximation to clothing seen among them. Above the elbow the men usually wore a bandage of net work, in which was stuck a short piece of strong grass, called _tomo_, and used as a tooth pick; but the most remarkable circumstance in their persons was, that the whole of them appeared to have undergone the Jewish and Mahometan rite of circumcision. The same thing was before noticed in a native of Isle Woodah, and in two at Wellesley's Islands; it would seem, therefore, to be general on the west side of the Gulph of Carpentaria; but with what view it may be done, or whence the custom were received, it is not in my power to state. No such practice was found on the South or East Coasts, nor was it observed in the natives of the islands in Torres' Strait, who however, go naked as the Australians.
[* In Van Diemen's Land, according to captain Cook and succeeding visitors, and on the North-west Coast, according to Dampier, the inhabitants have woolly hair; in which particular they are different from the race above mentioned. Which of them may be aborigines can be only conjectured, until the interior of the new continent shall be explored.]
No other weapons than spears were seen amongst these people; but they were not unacquainted with bows and arrows. It is probable that they have bark canoes, though none were seen, for several trees were found stripped, as if for that purpose; yet when Bongaree made them a present of the canoe brought from Blue-mud Bay, they expressed very little pleasure at the gift, and did not seem to know how to repair it.
That this bay had before received the visits of some strangers, was evinced by the knowledge which the natives had of fire arms; they imitated the act of shooting when we first landed, and when a musket was fired at their request, were not much alarmed. A quantity of posts was lying near the water, which had been evidently cut with iron instruments; and when we inquired of the inhabitants concerning them, they imitated with their hands the motion of an axe cutting down a tree, and then stopping, exclaimed _Poo!_ Whence we understood that the people who cut the wood had fire arms. This was all that could be learned from the natives; but from the bamboos and partitions of frame work found here, similar to those at Pellew's Group, they were doubtless the same Asiatic nation, if not the same individuals, of whom so many traces had been seen all the way from the head of the gulph. The propensity shown by the natives to steal, especially our axes, so contrary to all I have known and heard of their countrymen, is not only a proof that they had been previously visited by people possessing iron implements, but from their audacity it would appear, that the effect of fire arms was either not very certain in the hands of the strangers, or had seldom been resorted to in the punishment of aggression; and from the circumstance of the Indians bringing us a few berries, as a recompense for the last stolen axe, it should seem that they had been accustomed to make very easy atonements for their thefts. I have some hope that those who may follow us will not be robbed, at least with so much effrontery; and at the same time, that the inhabitants of Caledon Bay will not avoid, but be desirous of further communication with Europeans.
I do not know that the language at any two parts of Terra Australis, however near, has been found to be entirely the same; for even at Botany Bay, Port Jackson, and Broken Bay, not only the dialect, but many words are radically different;* and this confirms one part of an observation, the truth of which seems to be generally admitted: that although similarity of language in two nations proves their origin to be the same, yet dissimilarity of language is no proof of the contrary position. The language of Caledon Bay may therefore be totally different to what is spoken on the East and South Coasts, and yet the inhabitants have one common origin; but I do not think that the language is absolutely and wholly different, though it certainly was no better understood by Bongaree than by ourselves. In three instances I found a similarity: the personal pronoun of Port Jackson, _gni-a_ (I), was used here, and apparently in the same sense; when inquiry was made after the axe, the natives replied "_Yehangeree py_," making signs of beating; and _py_ signifies to beat, in the Port-Jackson language; the third instance was of the lad Woga calling to Bongaree in the boat, which after he had done several times without being answered, he became angry, and exclaimed _Bongaree-gah!_ in a vehement manner, as Bongaree himself would have done in a similar case. For the following list of words I am principally indebted to Mr. Brown, naturalist to the expedition; who remarked that the word here for eye was very nearly the same with that used, both at King George's Sound and Port Jackson, to express the same organ.
[* This multiplicity of tongues in the same country presents an extraordinary contrast with the _islands_ in the Great Ocean, where, from the Sandwich Isles near the northern tropic, to the furthest extremity of New Zeeland in 47° south, the language is almost every where the same; and with so little difference of dialect, that the several inhabitants have not much difficulty to understand each other.]
[LIST OF ENGLISH WORDS AND THOSE USED BY THE PEOPLE AT CALEDON BAY TO EXPRESS THE SAME IDEA.--not included in ebook.]
In collecting the words some errors may possibly have been made, either from misunderstanding the natives or from their deceiving us intentionally; for after the trick put upon Mons. Labillardière at the Friendly Islands, in the words given him for the high numerals, they are always to be suspected.
During the week we remained in Caledon Bay, the following astronomical observations were taken.
_Latitude_ from three observations to the north and south, taken in a boat astern of the ship and reduced to the tents on Point Alexander, 12° 47' 16" S.
_Longitude_ from twelve sets of distances of stars east and west of the moon, taken on a stand by lieut. Flinders, and of which the individual results are given in Table VI. of the Appendix No. I, 136° 35' 47.5" E.
The rates of the time keepers were found from morning's altitudes of the sun in an artificial horizon, between Feb. 3 and 8; and the means, with the errors from mean Greenwich time at noon there on the 9th, were as under:
Earnshaw's No. 543, slow 2h 41' 0.91" and losing 16.53" per day. Earnshaw's No. 520, slow 2h 27' 19.55" and losing 30.83" per day.
No. 520 had been accidentally let down in Blue-mud Bay, whence its longitude is not now noticed; that given by No. 543 on Feb. 3, with the rate from Observation Island, was 136° 43' 3.5", or 7'16" greater than the lunars. Were a rate used, equally accelerated from that of Observation Island to what was found in Caledon Bay, the longitude would be 0' 55" less than the lunars; but during the twelve days occupied in circumnavigating Groote Eylandt, it was proved that this time keeper was keeping its former rate, and consequently the acceleration cannot here be admitted.
In constructing the chart of the coast and islands between Pellew's Group and Caledon Bay, a time keeper was required only in laying down the south and east sides of Groote Eylandt, and the main coast up to Cape Barrow; in all the remaining parts the longitude was preserved by a connected chain of bearings, mostly taken on shore. The time-keeper reckoning from Observation Island, and that by survey worked back from the fixed point in Caledon Bay, meet each other on Jan. 5 p.m. at Connexion Island; and the difference was there found to be 2' 41", which the time keeper gave more to the east. This may have arisen from Observation Island being laid down in a longitude too great by that quantity, or Caledon Bay too little, or from a small error in each; but the time keeper was not thought entitled to such perfect confidence, as to cause an alteration to be made in these stations. The difference of 2' 41" is therefore corrected by applying -16.3" of longitude per day to the time keeper, from Observation to Connexion Island; Groote Eylandt is laid down mostly from the time keeper, with the fixed correction -2' 41" all round; and from thence to Caledon Bay the chart is constructed from bearings and observed latitudes.
The mean _dip_ of the south end of the needle, observed at the tents, was 36° 28'.
_Variation_ of the theodolite, 2° 20' E.
On board the ship, at anchor off the south-west side of the inner island at the entrance, the variation from three compasses, with the head N. W. by W., was 2° 26'; by the surveying compass alone, 2° 46' east, and this, which I consider to be the best, would be, corrected, 1° 14' E.
At my different stations on shore, the variation seemed to be between 2° and 2° 20' east; except on the north-east end of the outer island in the entrance, where it appeared to be no more than 1° 30'.
The rise of _tide_ in Caledon Bay was so small, that nothing certain could be determined on board, either upon the quantity or the time; but it appeared from the observations of lieutenant Fowler at the tents, that there were two tides in the day, the rise of which varied from 3 feet 10, to 4 feet 10 inches; and that the time of high water took place at _nine hours and a half after_ the moon passed over and under the meridian.
On board the ship, the range of the thermometer was from 83° to 87°, nearly as it had been from first entering the Gulph of Carpentaria; and on shore it was probably 10° higher. Several of our people were ill of diarrhoeas at this time, accompanied with some fever, which was attributed by the surgeon to the heat and the moist state of the atmosphere; for since December, when the north-west monsoon began, not many days had passed without rain, and thunder squalls were frequent. Exposing the head uncovered to the sun, more especially if engaged in strong exercise, was proved to be very dangerous here; I lost one man in Blue-mud Bay from a want of due precaution in this particular, and at this place two others very narrowly escaped. Musketoes were numerous and exceedingly troublesome on shore, as also the black flies; but no venemous reptiles were seen in our limited excursions round Caledon Bay. The mercury in the barometer stood between 29.90 and 29.95 inches, in the rainy weather with strong winds from the eastward; but with fine weather and variable winds, more especially from the south and westward, it descended to 29.80 inches.
