Light northern winds favoured us for two days; but returning to the south-west, and sometimes blowing strong, it was the 20th in the evening before the sloop was secured in Port Jackson, although the current had set us 210 miles on the way.
I must acknowledge myself to have been disappointed in not being able to penetrate into the interior of New South Wales, by either of the openings examined in this expedition; but, however mortifying the conviction might be, it was then an ascertained fact, that no river of importance intersected the East Coast between the 24th and 39th degrees of south latitude.
CONCLUSIVE REMARKS.
The account of the discoveries which resulted from the establishment of the colony in New South Wales, closes with this expedition; and it remains only to point out what was wanted to be done in these parts of Terra Australis.
(Atlas, Plate I.)
In Van Diemen's Land, the opening round Point St. Vincent and the space between Maria's Island and Cape Portland required to be further explored. The north side also, from the want of a time keeper in the Norfolk, required to have the longitude of its points better ascertained; and that the bight between Circular Head and Cape Grim should be examined. In Bass' Strait, some of the islands were known, but the middle of the strait and its western entrance were in want of much investigation, before it could be deemed a safe passage for ships; and the greater part of the coast on the north side, remained as laid down by Mr. Bass, with all the uncertainty attending the navigation of an open boat.
On the east coast of New South Wales, from Bass' Strait to Bustard Bay in latitude 24 deg., the shore might be said to be well explored; but from thence northward to Cape York, there were several portions which had either been passed by captain Cook in the night, or at such a distance in the day time, as to render their formation doubtful: The coast from 15 deg. 30' to 14 deg. 30' was totally unknown.
The following openings or bights had been seen and named by captain Cook, but were yet unexamined: Keppel and Shoal-water Bays; Broad Sound; Repulse, Edgecumbe, Cleveland, Halifax, Rockingham, and Weary Bays. To the northward of these were Weymouth, Temple, Shelburne, and Newcastle Bays; and perhaps many others which distance did not permit our great navigator to notice. There was also a numerous list of islands, of which a few only had been examined; and several were merely indicated from a distant view.
From 16 deg. northward to Cape York, an extensive chain of reefs had been found to lie at a considerable distance from the coast, without side of the islands; and two vessels from Port Jackson had met with others further south, extending nearly from 21 deg. to 23 deg.. It was of importance to ascertain the limits of these vast bodies of coral, were it only on account of the ships employed in the whale fishery; but in the view to future settlements within the tropic, it was necessary to be known whether these reefs might form such a barrier to the coast, as to render it inaccessible from the eastward: if not, then the open parts were to be ascertained.
Of the persons, manners, and customs of the inhabitants, little new information could be expected. The skirts of their country had been examined in the southern parts, and extensive collections in natural history made there; but to the north of Endeavour River, the country had been seen only at a distance. The vast interior of this new continent was wrapped in total obscurity; and excited, perhaps on that very account, full as much curiosity as did the forms of the shores. This part of the subject, however, will scarcely be thought to belong to a naval expedition; except in so much as rivers and other inlets might conduce to obtaining the desired information.
* * *
On a general review of the various objects in Terra Australis, to which investigation might be usefully directed at the commencement of the nineteenth century, and in which natural history, geography, navigation, and commerce were so much interested, the question, Why it should have been thought necessary to send out another expedition? will no longer be asked. But rather it will be allowed that, instead of one, there was ample room for two or three ships; each to be employed for years, and to be conducted with a zeal and perseverance not inferior to the examples given by the best navigators.
On the arrival of His Majesty's ship Reliance in England, at the latter end of 1800, the charts of the new discoveries were published, and a plan was proposed to the Right Hon. SIR JOSEPH BANKS for completing the investigation of the coasts of Terra Australis. The plan was approved by that distinguished patron of science and useful enterprise; it was laid before EARL SPENCER, then first Lord Commissioner of the Admiralty; and finally received the sanction of HIS MAJESTY, who was graciously pleased to direct that the voyage should be undertaken; and I had the honour of being appointed to the command.

1801. JANUARY.
[IN ENGLAND. SHEERNESS.]
On the 19th of January 1801, a commission was signed at the Admiralty appointing me lieutenant of His Majesty's Sloop INVESTIGATOR, to which the name of the ship, heretofore known as the Xenophon, was changed by this commission; and captain John Henry Martin having received orders to consider himself to be superseded, I took the command at Sheerness on the 25th of the same month.
The Investigator was a north-country-built ship, of three-hundred and thirty-four tons; and, in form, nearly resembled the description of vessel recommended by captain Cook as best calculated for voyages of discovery. She had been purchased some years before into His Majesty's service; and having been newly coppered and repaired, was considered to be the best vessel which could, at that time, be spared for the projected voyage to Terra Australis.
The ship was in a state of re-equipment; but, on obtaining permission from the Navy Board to fit her out in such manner as I should judge necessary, without reference to the supplies usually allotted to vessels of the same class, all the stores were returned, and others of the best quality demanded, upon a more extensive scale. Such of the officers and crew as were aged, or did not volunteer for this particular service, were discharged; and able young men were received in lieu from His Majesty's ship Zealand, on board of which the flag of vice-admiral Graeme was flying at the Nore. Upon one occasion, where eleven volunteers were to be received from the Zealand, a strong instance was given of the spirit of enterprise prevalent amongst British seamen. About three hundred disposable men were called up, and placed on one side of the deck; and after the nature of the voyage, with the number of men wanted, had been explained to them, those who volunteered were desired to go over to the opposite side. The candidates were not less than two-hundred and fifty, most of whom sought with eagerness to be received; and the eleven who were chosen, proved, with one single exception, to be worthy of the preference they obtained.
In making the various alterations required in the ship, and in performing the duties incident to an equipment of this nature, I received the most ready concurrence and assistance from Isaac Coffin, Esq., (now vice-admiral Sir Isaac Coffin, Bart.) the resident naval commissioner at Sheerness. At his suggestion I had the ship coppered two streaks higher than before, and took on board a spare rudder, which, after being fitted, was stowed away in pieces, ready against those accidents to which ships employed in examining new, or little known coasts, are more peculiarly liable. To Mr. Whidbey, the master attendant, who had served in the expedition of captain Vancouver. I was also much indebted, for his valuable advice and assistance in the selection of the proper stores. Both these officers constantly took pleasure in promoting whatever could be useful to the voyage, or add to our comfort and convenience; and in some cases, our wants, and even wishes, were anticipated.
FEBRUARY. MARCH.
February 16, I was promoted to the rank of commander. On the 14th of the following month, the guns, twelve six-pounders, with their ammunition and a chest of fire works were received; and the provisions and stores being all on board on the 27th, and the ship ready for sea, we dropped out to the Nore. I was anxious to arrive upon the coasts of Terra Australis in time to have the whole of the southern summer before me; but various circumstances retarded our departure, and amongst others, a passport from the French government, to prevent molestation to the voyage, had not arrived. I took advantage of this delay to remedy an inconvenience, under which we were otherwise likely to suffer. The quantity of provisions necessary to be carried out did not leave room in the holds for more water than fifty tons; but by removing ten of the long guns, and substituting a few light carronades which could be carried on the upper deck, ten tons more of water might be received, without reducing our efficient strength; for the ship was too deep to admit of the guns below being used in bad weather, whereas the carronades would be always serviceable. My application to have this exchange made, was complied with; and on May 20 it was effected.
MAY.
On the 22nd, a set of astronomical and surveying instruments, for the use of myself and officers, was sent down by direction of the Navy Board; as also various articles for presents to, and barter with, the native inhabitants of the countries to be visited, and many for our own use and convenience. Amongst the latter were most of the books of voyages to the South Seas, which, with our own individual collections, and the Encyclopedia Britannica, presented by the Right Hon. Sir Joseph Banks, formed a library in my cabin for the use of all the officers. Every chart at the Admiralty, which related to Terra Australis and the neighbouring islands, was copied for us under the direction of the late hydrographer, Alexander Dalrymple, Esq.; who also enriched our stock of information by communicating all such parts of his works as were appropriate to the voyage.
The expense to officers of an outfit for several years, was much alleviated by the liberality of the Hon. East-India Company. The sum of L600. was ordered by the Court of Directors, to be paid as an allowance to the men of science, to the officers of the ship, and myself, for our tables; and the same sum to be given at the conclusion of the voyage. This allowance the directors were pleased to make, from the voyage being within the limits of the Company's charter, from the expectation of our examinations and discoveries proving advantageous to their commerce and the eastern navigation, and partly, as they said, for my former services.
On the 26th, I received orders to proceed round to Spithead; but the winds being generally from the westward, we did not arrive there before the 2nd of June. A circumstance occurred during the passage, which, amongst many others, showed the necessity there was for a regulation since adopted, to furnish His Majesty's ships with correct charts. No master had been appointed to the Investigator; nor was any officer on board intimately acquainted with the navigation of the Channel; and having been most of my life engaged in foreign voyages, I was under the necessity, after leaving the pilot in the Downs, to trust almost wholly to my chart, which was that of Mr. J. H. Moore. In working up under Dungeness, on the evening of May 28, we made a trip in shore, towards the town of Hythe, as I supposed from the chart. A little after six, the officer of the watch had reported our distance from the land to be near two leagues; and there being from 10 to 14 fathoms marked within two or three miles of it, and no mention of any shoal lying in the way, I intended to stand on half an hour longer; but in ten minutes, felt the ship lifting upon a bank. The sails were immediately thrown aback; and the weather being fine and water smooth, the ship was got off without having received any apparent injury.
This sand is laid down in the Admiralty charts, under the name of the Roar; and extends from Dungeness towards Folkstone, at the distance of from two and a half, to four miles from the land. The leadsman, having found no bottom with 15 fathoms at ten minutes before six, had very culpably quitted the chains when his watch was out, without taking another cast of the lead; and the ship, in going at the rate of two knots and three-quarters, was upon the bank at twenty minutes after six; so that it appears to be steep on the east side.
The bearings given by the azimuth compass, whilst the ship was aground, were as under:
Dungeness light house, S. W. Lidd church W. by S. 1/2 S. Town of Dim, but taken to be Hythe, N. W. by N. Cheriton church, then supposed to be Folkstone, E. N. E. Cliffy eastern extreme of the land, near Dover, E. 1/2 N.
The distance from the town of Hythe (Dim,) was guessed to be not less than two-and-half, nor more than four miles.
[IN ENGLAND. PORTSMOUTH.]
JUNE.
In consequence of this accident, we went into Portsmouth Harbour and into dock on June 10; and it being ascertained that the ship had received no injury, we returned to Spithead next day, and moored as before, waiting for orders. On the 18th, commissioner Sir Charles Saxton paid the ship's company their wages up to the end of May, with an advance of two months; and the officers were permitted to draw bills for three months pay in advance.
JULY.
On July 17, I received the following instructions for the execution of the voyage.
By the Commissioners for executing the office of Lord High Admiral of the United Kingdom of Great Britain and Ireland, etc.
Whereas the sloop you command has been fitted and stored for a voyage to remote parts; And whereas it is our intention that you should proceed in her to the coast of New Holland for the purpose of making a complete examination and survey of the said coast, on the eastern side of which His Majesty's colony of New South Wales is situated; You are hereby required and directed to put to sea the first favourable opportunity of wind and weather, and proceed with as little delay as possible in execution of the service above-mentioned, repairing in the first place to Madeira and the Cape of Good Hope in order to take on board such supplies of water and live stock as you may be in want of.
Having so done you are to make the best of your way to the coast of New Holland, running down the said coast from 130 degrees of east longitude to Bass's Strait; (putting if you shall find it necessary, into King George the third's Harbour for refreshments and water previous to your commencing the survey;) and on your arrival on the coast, use your best endeavours to discover such harbours as may be in those parts; and in case you should discover any creek or opening likely to lead to an inland sea or strait, you are at liberty either to examine it, or not, as you shall judge it most expedient, until a more favourable opportunity shall enable you so to do.
When it shall appear to you necessary, you are to repair to Sydney Cove for the purpose of refreshing your people, refitting the sloop under your command, and consulting with the governor of New South Wales upon the best means of carrying on the survey of the coast; and having received from him such information as he may be able to communicate, and taken under your command the Lady Nelson tender, which you may expect to find at Sydney Cove, you are to recommence your survey, by first diligently examining the coast from Bass's Strait to King George the third's Harbour; which you may do either by proceeding along shore to the westward, or, in case you should think it more expedient., by proceeding first to King George's Sound, and carrying on your survey from thence to the eastward.
You are to repair from time to time, when the season will no longer admit of your carrying on the survey, to Sydney Cove; from whence your are to return in the execution of these instructions, so soon as circumstances will enable you so to do.
You are to be very diligent in your examination of the said coast, and to take particular care to insert in your journal every circumstance that may be useful to a full and complete knowledge thereof, noting the winds and weather which usually prevail there at different seasons of the year, the productions and comparative fertility of the soil, and the manners and customs of the inhabitants of such parts as you may be able to explore; fixing in all cases, when in your power, the true positions both in latitude and longitude of remarkable head lands, bays, and harbours, by astronomical observations, and noting the variation of the needle, and the right direction and course of the tides and currents, as well as the perpendicular height of the tides; and in case, during your survey, any river should be discovered, you are either to proceed yourself in the tender, or to direct her commander to enter it, and proceed as far up as circumstances will permit; carefully laying down the course and the banks thereof, and noting the soundings, going on shore as often as it shall appear probable that any considerable variation has taken place either in the productions of the soil or the customs of the inhabitants; examining the country as far inland as shall be thought prudent to venture with the small number of persons who can be spared from the charge of the vessel, wherever there appears to be a probability of discovering any thing useful to the commerce or manufactures of the United Kingdom.
When you shall have completely examined the whole of the coast from Bass's Strait to King George the third's Harbour, you are, at such times as may be most suitable for the purpose, (which may be seen on a reference to Mr. Dalrymple's memoir, an extract of which accompanies this,) to proceed to and explore the north-west coast of New Holland, where, from the extreme height of the tides observed by Dampier, it is probable that valuable harbours may be discovered.
Having performed this service, you are carefully to examine the Gulf of Carpentaria, and the parts to the westward thereof, between the 130th and 139th degrees of east longitude; taking care to seize the earliest opportunity to do so, when the seasons and prevalent winds may be favourable for visiting those seas.
When you shall have explored the Gulf of Carpentaria and the parts to the westward thereof, you are to proceed to a careful investigation and accurate survey of Torres' Strait, and when that shall have been completed, you are to examine and survey the whole of the remainder of the north, the west, and the north-west coasts of New Holland, and especially those parts of the coast most likely to be fallen in with by East-India ships in their outward-bound passages. And you are to examine as particularly as circumstances will allow, the bank which extends itself from the Trial Rocks towards Timor, in the hope that by ascertaining the depth and nature of the soundings thereon, great advantage may arise to the East-India Company's ships, in case that passage should hereafter be frequented by them.
So soon as you shall have completed the whole of these surveys and examinations as above directed, you are to proceed to, and examine very carefully the east coast of New Holland, seen by captain Cook, from Cape Flattery to the Bay of Inlets; and in order to refresh your people, and give the advantage of variety to the painters, you are at liberty to touch at the Fejees, or some other of the islands in the South Seas.
During the course of the survey, you are to use the tender under your command as much as possible; moving the Investigator onward from one harbour to another as they shall be discovered, in order that the naturalists may have time to range about and collect the produce of the earth, and the painters allowed time to finish as many of their works as they possibly can on the spot where they may have been begun: And when you shall have completed the whole of the surveys and examinations as abovementioned, you are to lose no time in returning with the sloop under your command to England for farther orders, touching on your way, if necessary, at the Cape of Good Hope, and repairing with as little delay as possible to Spithead, and transmit to our secretary an account of your arrival.
During your continuance on the service above-mentioned, you are, by all proper opportunities, to send to our secretary for our information, accounts of your proceedings and copies of the surveys and drawings which you shall have made, and such papers as the Naturalist and the Painters employed on board may think proper to send home; and upon your arrival in England you are immediately to repair to this office in order to lay before us a full account of your proceedings in the whole course of your voyage; taking care before you leave the sloop to demand from the officers and petty officers the log books and journals which they may have kept and such drawings and charts as they may have taken, and to seal them up for our inspection.
And whereas you have been furnished with a plant cabin for the purpose of depositing therein such plants, trees, shrubs, etc., as may be collected during the survey above-mentioned, you are, when you arrive at Sydney Cove, to cause the said plant cabin to be fitted up by the carpenter on the quarter deck of the sloop you command, according to the intention of its construction; and you are to cause boxes for containing earth to be made and placed therein, in the same manner as was done in the plant cabin carried out by the Porpoise store ship, which plant cabin you will find at Sydney Cove.
You are, to place the said plant cabin, with the boxes of earth contained in it, under the charge and care of the naturalist and gardener, and to cause to be planted therein during the survey, such plants, trees, shrubs, etc., as they may think suitable for the Royal Gardens at Kew; and you are, as often as you return to Sydney Cove, to cause the said plants to be deposited in the governor's garden and under his charge, there to remain until you sail for Europe: And so soon as you shall be preparing to return home, you are to cause the small plant cabin to be removed from the sloop's quarter deck, and the one brought out by the Porpoise (which is something larger), to be placed there in its stead. In this last mentioned cabin the naturalist and gardener are to place the plants, trees, shrubs, etc., which may have been collected during the survey, in order to their being brought home for His Majesty; and you are, so soon as the sloop shall arrive at any port in England, to give notice of her arrival to His Majesty's botanic gardener at Kew, and to transmit to him a list and state of the said plants etc., which the gardener employed under your orders is to furnish you with for that purpose.

The instructions were accompanied with the extract of a memoir from Mr. Dalrymple, respecting the winds and weather to be expected, principally upon the south coast of Terra Australis. Also with the following PASSPORT from the French government.
LE PREMIER CONSUL DE LA REPUBLIQUE FRANCAISE, sur le compte qui lui a ete rendu de la demande faite par le LORD HAWKESBURY au Citoyen Otto, commissaire du gouvernement Francais a Londres, d'un Passeport pour la corvette Investigator, dont le signalement est ci-apres, expediee par be gouvernement Anglais, sous le commandement du capitaine Matthew Flinders, pour un voyage de decouvertes dans la Mer Pacifique, ayant decide que ce passeport seroit accorde, et que cette expedition, dont l'objet est d'etendre les connoissances humaines, et d'assurer davantage les progres de la science nautique et de la geographie, trouveroit de la part du gouvernement Francais la surete et la protection necessaires.
LE MINISTRE DE LA MARINE ET DES COLONIES ordonne en consequence a tous les commandants des batiments de guerre de la Republique, a ses agens dans toutes les colonies Francaises, aux commandants des batiments porteurs do lettres de marque, et a tous a autres qu'il appartiendra, de laisser passer librement et sans empechement, ladite corvette Investigator, ses officiers, equipage, et effets, pendant la duree de leur voyage; de leur permettre d'aborder dans les differents ports de la Republique, tant in Europe que dans les autres parties du monde, soit qu'ils soient forces par le mauvais tems d'y chercher un refuge, soit qu'ils viennent y reclamer les secours et les moyens de reparation necessaires pour continuer leur voyage. Il est bien entendu, cependant, qu'ils ne trouveront ainsi protection et assistance, que dans le cas ou ils ne se seront pas volontairement detournes de la route qu'ils doivent suivre, qu'ils n'auront commis, ou qu'ils n'annonceront l'intention de commettre aucune hostilite contre la Republique Francaise et ses allies, qu'ils n'auront procure, ou cherche a procurer aucun secours a ses ennemis, et qu'ils ne s'occuperont d'aucune espece de commerce, ni de contrebande.

In consequence of this passport, I received directions from the Admiralty "to act in all respects towards French ships as if the two countries were not at war; and," it was added, "with respect to the ships and vessels of other powers with which this country is at war, you are to avoid, if possible, having any communication with them; and not to take letters or packets other than such as you may receive from this office, or the office of His Majesty's secretary of state."
From His Grace the duke of Portland, I carried an order to the governor of New South Wales to place the brig Lady Nelson under my command, on arriving at Port Jackson; and also one from the Admiralty, directing the governor, in his quality of senior naval officer, not to take the Investigator from the purposes of the voyage; but to assist me with all the means in his power to put them into execution.
So soon as my sailing orders were received, demands were sent on shore for provisions to replace what had been consumed at Spithead; and they came on board next morning, when the ship was unmoored. We were able to stow a proportion of provisions for twelve months, bread excepted, of which only seven months could be taken, including a part in flour. Of salt meat I took for eighteen months, knowing that little reliance could be had upon the colony in New South Wales for that article; and further to guard against any detriment to the voyage from a want of provisions, I left an application to the Admiralty for a general supply, for twelve months; to be sent after me, and lodged in the store houses at Port Jackson for our sole use.
Of the various extra provisions usually furnished as preservatives of health to the crews of His Majesty's ships going upon similar service, our supply was abundant; and the surgeon was as liberally furnished with antiscorbutic medicines.
The complement of the Xenophon had been seventy-five men; but on the name and destination of the ship being changed, the following establishment was ordered. The names of the officers are added to the list, and also of the men of science who took part in the expedition.
Astronomer, 1 John Crosley. Naturalist, 1 Robert Brown. Natural-history painter, 1 Ferdinand Bauer. Landscape painter, 1 William Westall. Their servants, 4 Gardener, 1 Peter Good.

Serjeant, 1 Corporal, 1 Drummer, 1 Privates, 12 — Complement 83 Deficiency. Sailmaker, 1 Master at arms, 1 Quarter masters, 2 Cook's mate, 1 Carpenter's crew, 1 Seaman, 1 — Deficient of complement 7 —
The deficiency of seven, and the two young gentlemen more than allowed, left the whole number of persons on board to be eighty eight, at the time of sailing.
Mr. Crosley, the astronomer, brought with him an assortment of instruments from the Board of Longitude; part for use at sea, and the larger instruments for making observations on shore, at such ports and bays as we might anchor in during the voyage. His time keepers were the numbers 543 and 520, and watch 465 of Earnshaw; and the numbers 176 and 82 of Arnold. Amongst the instruments supplied to me by the Navy Board, which were unconnected with the above and mostly intended for surveying, was Arnold's watch number 1786, sent for the purpose of being taken up rivers in the tender, or in boats. Its error from mean Greenwich time, at noon July 17, was 2' 38.71" slow, and its rate of losing per day 4.41". This error and rate were given me by Mr. Bayly, mathematical master of the naval academy at Portsmouth, who had the kindness to take charge of the watch during our stay at Spithead.

1801. JULY.
[TOWARDS MADEIRA.]
On July 18 we sailed from Spithead; and in the afternoon of the 20th, having a light breeze from the eastward, with fine weather, our departure was taken from the Start, bearing N. 18 deg. W. five or six leagues. On the following day we fell in with vice-admiral Sir Andrew Mitchell, with a detachment of four three-decked ships from the grand fleet cruising before Brest. It was gratifying to learn from the admiral, that although he had not dropped an anchor for seventeen weeks, there was not a scorbutic man on board; nor any in the sick list, except from slight hurts.
The variation of the compass off St. Alban's Head, had been observed by Mr. Thistle, the master, to be 28 deg. 43' west, from amplitude; off the Start it was 29 deg. 34' from a western azimuth, and 29 deg. 30' from amplitude; but on the following afternoon, where the variation should have been nearly the same, azimuths gave 24 deg. 12' and an amplitude 23 deg. 43' west; the mean 5 deg. 35' less than off the Start. The same compass was always used, and the ship's head was at west (magnetic), or within one point of it, in all the cases; but in the first observations the compass was placed on the binnacle, and in the last, was upon the booms. In order to ascertain clearly what effect this change of place did really produce, I took observations a few days afterward [MONDAY 27] with every compass on board, and Mr. Thistle did the same upon the booms, ten or twelve feet before the main mast, where the compasses were as far removed from any quantity of iron, as they could be placed in any part of the ship. The head was south-west by the steering compass, our latitude was 38 deg. 1' north, longitude 14 deg. 18' west, and the results were as under.
Binnacle. Booms. Variation from an azimuth compass by Walker, deg. ' deg. ' marked No 1: mean of both sides of the vane. 25 47 22 17 W. From a ditto marked No. 2, 25 35 19 15 ditto marked No. 3, 24 41 21 27 Walker's meridional compass, 25 46 - - Ditto used as a common azimuth, 25 51 20 35 Compass made by Adams, 25 44 21 9 ——————— Means, 25 34 20 57 W. ———————
Thus a change of place from the binnacle to a little before the centre of the ship, produced an alteration of 4 deg. 37' in the mean variation, the same way as, but a less quantity than Mr. Thistle had found it off the Start, when the ship's head was west. The true variation I judge to have been 23 deg., and that the observations on the booms showed 2 deg. too little, and those on the binnacle 21/2 deg. too much. The error in excess, upon the binnacle, appeared to continue so long as the ship was in the northern hemisphere and the head to the westward; but it diminished gradually as we approached the equator, and the observations on the binnacle and booms then nearly coincided. This example is sufficient to show the impropriety of allowing a variation upon the ship's course, from observations taken elsewhere than at the binnacle.
THURSDAY 30 JULY 1801.
We continued our course for Madeira, with fair winds. Our latitude on the 30th, was 30 deg. 5' north, longitude 15 deg. 31' west; and in the afternoon Porto Santo was seen, bearing west-north-west; the wind then became light and variable, and soon afterwards died away. The variation observed on the binnacle by the master, when the head was south-west-by-south, was 22 deg. 45', but on the booms 19 deg. 51'; the true variation being as I believe, 20 deg. 51' west.
FRIDAY 31 JULY 1801.
It was calm on the 31st, and I had a boat lowered down and went round the ship with the carpenter, to inspect the seams near the water line, for we had the mortification to find the ship beginning to leak so soon as the channel was cleared, and in the three last days she had admitted three inches of water per hour. The seams appeared sufficiently bad, especially under the counter and at the butt ends, for the leak to be attributable to them; and as less water came in when the ship was upright than when heeling to a beam wind, I hoped the cause need not be sought lower down. Before hoisting up the boat, a small hawke's-bill turtle was picked up; and between this time and that of anchoring in Funchal Road, several others were seen, and a second, weighing about thirty pounds, was caught.
SATURDAY AUGUST 1 1801.
Aug. 1, at noon, Porto Santo bore N. 11 deg. W., and the rocky islands called Dezertas, from N. 65 deg. to S. 85 deg. W. distant three leagues. The south end of these islands lies, by our observations, in latitude 32 deg. 24' 20" north, which differs less than one mile from its position in Mr. Johnston's chart of the Madeiras. There being little wind next morning [SUNDAY AUGUST 2], I went off in one of the cutters, accompanied by Messieurs Brown and Bauer, the naturalist and natural-history painter, to the southernmost island, called Bujio, which was not far distant. On the way, I shot several birds of the puffin kind, one of which had a fathom of small brass wire attached to its wing. The distance of the land proved to be more considerable than was expected; and there being a current setting southward we did not reach the shore until near three in the afternoon, when it was necessary to think of returning.
[AT MADEIRA—FUNCHAL ROAD]
A small ledge of rocks, which projected a little from under the cliffs at the south-west part of Bujio, afforded a landing place; but it was impossible to ascend the top of the island. We saw no other animated beings than a few birds something like green linnets, but which were said, at Madeira, to have been canary birds; and the other productions were scarcely sufficient to afford amusement even to a naturalist. The cliffs over head showed marks of irregular stratification, and in some of the lines there was a red tinge, apparently of iron. The base underneath was black and honey-combed, as if it had been in the fire, resembling in this respect the common stone at Funchal.
We left Bujio well satisfied that, so far as we could judge of the islands, the name Dezertas, or Desert Islands, was well chosen; and soon after dusk, reached the ship. There was then a good breeze from the north-eastward, with which we steered for Madeira. tacking occasionally during the night, to take advantage of the different flaws of wind. At the following noon [MONDAY 3 AUGUST], the ship was under Brazen Head, which forms the east side of Funchal Road; and being there becalmed, we towed in with the boats, and came to an anchor at four o'clock, in 22 fathoms, steadying with a kedge to the north-west. In this situation, which seems to be as good as any in the road, the bearings by compass were as follow:
Brazen Head, S. 71 deg. E. Punta de Cruz, on the west side, N. 85 W. Loo Fort, distant one-third of a mile, N. 12 W.
The north-east winds usually prevail at Madeira in the summer season, and sometimes blow very strong. To reach Funchal Read, ships are accustomed to sail between the east end of Madeira and the Dezertas, before the wind. They are not very desirous of passing close to Brazen Head, where they would be becalmed, but keep off a mile or two, in the skirt of the north-east wind, until they are off the town, or even off Punta de Cruz, where they generally find a breeze from the south-west, which takes them to the anchorage. This south-west wind is the sea breeze of Funchal; and during the time we lay in the road, it usually set in at eight or nine o'clock in the morning, and prevailed as far as three or four miles in the offing, till sunset. A variable breeze comes off the land in the night; at which time it is recommended to ships to pass close to Brazen Head and tow into the road.
We found his Majesty's ship Argo lying here; and I waited upon captain James Bowen, immediately that the ship was secured. Lieutenant Flinders was sent, at the same time, to present my respects to the Portuguese governor, and to ask his Excellency's permission to purchase the necessaries of which we stood in need; as also for the scientific gentlemen to make such an examination of the natural productions of the island, as our short stay would allow. The first request was granted by the governor in polite terms, and accompanied with offers of assistance; but an answer to the second was deferred until he should see me.
This evening the ship was heeled three streaks, when it was found that she admitted more than three inches of water per hour; whereas, when upright, it scarcely amounted to one inch. Next morning [TUESDAY 4 AUGUST], therefore, the carpenters began caulking two seams above the copper, all round, whilst the seamen were employed in shifting the top masts and examining the rigging.
By the assistance of Joseph Pringle, Esq., the British consul, I procured boats from the shore to be sent for our empty water casks; and an ox was killed for our use, and wine prepared for embarkation. His Excellency, the governor, had appointed noon of this day to receive my visit; and I waited upon him in form, accompanied by the consul, who interpreted between us. The governor repeated his offers of assistance; and on being made to understand the nature of the excursions which our gentlemen desired to make into the country, he granted his permission with the utmost readiness. After I had answered some questions relative to the settlement of political affairs in the north of Europe, we took our leave; and were attended out by the officers in waiting, and saluted by the guard.
THURSDAY 6 AUGUST 1801.
On the 6th in the evening, our supply of provisions was received, and the caulking of the ship completed. The scientific gentlemen returned from an expedition towards the Pico Ruivo; which is the highest of a ridge of mountains occupying the central parts of the island, and is said to be 5067 feet, or nearly an English mile, above the level of the sea. The ascent was found to be very difficult; and this, with the heat of the weather and limitation of their time to this evening, disabled them from reaching the summit. It was late when they arrived at the shore; and in embarking abreast of the town, they had the misfortune to be swamped, and to lose the greater part of their collections and sketches, although the boat was managed by Portuguese watermen, accustomed to the place.
The best landing is behind the Loo Rock; but the stony beach in front of the town is usually safe in the summer time. It was so on our first arrival, until the strong eastern winds in the offing raised so much swell as to make it dangerous, even for people experienced in the management of a boat in the surf.
The town of Funchal is placed at the foot of a mountain, which projects from the great central ridge; and the houses being mostly white, they form a strong, but agreeable contrast with the back land. At different elevations up the side of the mountain, are scattered the country houses of the richer inhabitants, placed amongst groups of trees and surrounded with vines. These, with a convent dedicated to Our Lady of the Mountain, which, like the houses, is white, but partly hidden by foliage, give to the whole a picturesque and pleasing appearance from the ships in the road. The town is larger, and there was more trade and activity in it than I was prepared to expect in a small colony, where the students of the college and ecclesiastics of different orders form no inconsiderable part of the superior class of inhabitants. Several British merchants reside at Madeira; their houses of business are at Funchal, but their favourite residences are upon the side of the mountain. I accompanied captain Bowen to one of these, the hospitable seat of Mr. Murdoch, and thought it one of the prettiest places I had seen. The house of Mr. Pringle, the consul, was my home when on shore; indeed the politeness of our countrymen prevented me from experiencing the accommodation afforded to strangers at a house in the town, dignified with the name of hotel. Some of our gentlemen complained of its being miserable enough, even without the swarms of fleas and other vermin by which they were molested.
His Majesty's ships Argo, Carysfort, Falcon, and transports, under the command of captain James Bowen, had arrived in Funchal Road about nine days before us; having on board the 85th regiment under colonel Clinton. After making their dispositions, the two commanders sent to inform the Portuguese governor, that His Britannic Majesty, considering the probability of an attack from the French upon the island, had sent troops to assist in its defence; and they demanded permission for the forces to land. A council was called by the governor; and it being agreed that even were they inclined yet no effectual resistance could be made, the permission was given, and a place assigned for the encampment of the troops to the west of the town. A part of the 85th was afterwards quartered in the Loo Fort and in that of St. Diego, which command both the town and the road; and the men were employed in putting these fortifications into a state of defence.
These arrangements caused no change in the administration of the government, nor in the trade of the island; but the governor was said to be not satisfied that his conduct would be approved. On the day of our arrival, he received intelligence of peace being concluded between Portugal and Spain, but that the war with France was continued; and before we sailed, His Majesty's sloop Voltigeur brought despatches from the Court of Lisbon, which directed the governor to receive the British troops; and it was supposed that every thing connected with the defence of the island would be committed to them. This was the state of things when I took leave of captain Bowen and of colonel Clinton.
Water, wine, and fresh beef, were the supplies procured at Madeira. Wine for the ship's company was charged at the enormous price of 5s. 8d. per gallon, and the beef at 10d. per pound; I therefore took only small quantities of each. For good Madeira, we paid as much as L42. the pipe. Fruit and onions were in abundance, and probably were not of less advantage to the health of the people than the more expensive articles.
The latitude observed in Funchal Road was 32 deg. 37' 44" north. The longitude, as given in the Requisite Tables, is 17 deg. 6' 15" west; but in the Connoissance des Temps for 1792, it is laid down by a member of the Academy of Sciences, probably the Chevalier de Borda, at 16 deg. 56' from Greenwich. Arnold's watch No. 1736, in my care, gave 16 deg. 22' 42", and the greatest longitude shown by any of the six time keepers was 16 deg. 54' 26". This was given by Earnshaw's watch No. 465, which had kept an uniform rate during fifteen months previously to its being brought on board. We made use of this watch to reduce some lunar observations taken a few days before arriving, and others after sailing, to the place of anchorage; and the result was as follows:
Ten sets of distances, east and west of the moon, taken by Mr. Crosley in Funchal Bay and afterwards, with a Troughton's sextant, 16 deg. 59' 21" W. Eight sets,* east and west, taken by me with a Troughton's circle and two sextants, before and afterwards, 16 51 28 ——————— West longitude of Funchal by lunar observations, 16 55 24 ———————
[* Four of these are uncorrected for the errors of the lunar and solar tables. They were taken Aug. 29, on which day no observation of the moon was made at Greenwich; and the errors observed on the 27th and 30th were so irregular, that no proportion can be made between them with any prospect of accuracy. Were the errors of the 30th applied, the longitude of Funchal would be 4' less.]
We were therefore induced to prefer the 16 deg. 56', in the Connoissance des Temps, as being nearer the true longitude of Funchal from Greenwich, than the 17 deg. 6' 15" of the Requisite Tables.
Every person had returned on board on Friday morning; and a young man, a native of Ireland, who had been sent here sick in a French cartel, applying to go the voyage, I ordered him to be entered, on the surgeon reporting him to be a fit man for His Majesty's service.
FROM MADEIRA—TOWARDS THE CAPE
On quitting Funchal Road, we were taken aback, at two o'clock, by the east-north-east wind, about two miles off Brazen Head. It blew so strong as to make it necessary to clew down all the sails; and until next morning [SATURDAY AUGUST 8], nothing above close-reefed top sails could be carried with safety. At noon, the log gave 162 miles from Funchal; but the cloudy weather did not admit of taking observations.
SUNDAY 9 AUGUST 1801
At daybreak of the 9th the island Palma was in sight, bearing S. 72 deg. E. ten or twelve leagues. Albacores and bonitas now began to make their appearance, and the officers and men were furnished with hooks and lines, and our harpoons and fizgigs were prepared. This day I ordered lime juice and sugar to be mixed with the grog; and they continued to be given daily to every person on board, until within a short time of our arrival at the Cape of Good Hope.
SATURDAY 15 AUGUST 1801
We carried fair, and generally fresh winds, until the 15th in the morning, when St. Antonio, the north-westernmost of the Cape-Verde Islands was in sight. At eight o'clock, the extremes bore N. 69 deg. E. and S. 13 deg. W., and the nearest part was distant four miles; in which situation no bottom could be found at 75 fathoms. A boat was observed near the shore, and our colours were hoisted; but no notice appeared to be taken of the ship.
The north-west side of St. Antonio is four or five leagues in length; and rises abruptly from the sea, to hills which are high enough to be seen fifteen, or more leagues from a ship's deck. These barren hills are intersected by gullies, which bore marks of much water having passed down them. By the side of one of these gullies, which was near the place where we lost sight of the boat, there was a path leading up into the interior of the island. The south-west and south points are low; they lie N. 14 deg. W. and S. 14 deg. E. and are five or six miles asunder. Between them, the land hollows back so as to form somewhat of a bay, which, if it afford good anchorage, as it is said to do, would shelter a ship from all winds between north and east-south-east. We did not observe any beach at the head of the bay, perhaps from having passed at too great a distance.
No observations could be taken for fixing the situation of this island; but in 1795, Mr. Crosley and myself made the high land near the south-west point to lie in 17 deg. 00' north, and by uncorrected lunar observations, in 25 deg. 12' west; which agrees well with the position of the north-west point, as given by captain Vancouver.* The variation from azimuth on the evening of the 14th, before making the land, was 13 deg. 51' west, and 13 deg. 3' this evening, when four leagues to the west of it; the compass being placed on the binnacle, and the ship's head south-south-west (magnetic) in both cases. The true variation here, at this time, I judge to have been 12 deg. 24' west. Captain Vancouver observed 12 deg. 32', in 1791; but it does not appear how the ship's head was directed.
[* Voyage round the World, Vol. I. page 10.]
Some distant land opened from the south point of St. Antonio, at S. 75 deg. E.; which I took to be a part of the island St. Lucia.
During the three days before making St. Antonio, the wind varied from the regular north-east trade, to east-north-east, and as far as south-east-by-east; and about the time of seeing the land, it dwindled to a calm. For three days afterwards it was light, and variable between north and south-east; after which it sometimes blew from the north-west and south-west, and sometimes from the eastward. These variable winds, with every kind of weather, but most frequently with rain, continued until the 23rd [SUNDAY], in latitude 11 deg. north and longitude 23 deg. west; when a steady breeze set in from the south-westward, and the weather became more settled and pleasant. The clouds were sufficiently dense to keep off the intense heat of the vertical sun, but did not often prevent us from obtaining daily observations for the latitude and longitude. At the same time with the south-west wind came a swell from the southward, which made the ship plunge considerably; and so far opened her leaks, that she again made two inches of water in the hour.
THURSDAY 27 AUGUST 1801
On the 27th, in latitude 6 deg. north and longitude 171/2 deg. west, a noddy was caught, and next day a swallow was found dead in my sleeping cabin. This poor little bird had been our companion for three or four days before, and had become a favourite. It was generally seen darting past the lee scuttles and ports, apparently after the flies which were carried out by the streams of air; sometimes it alighted upon the boats which hung on the ship's quarters, and more than once rested itself in the cabin where, at length, it was found dead.
WEDNESDAY 2 SEPTEMBER 1801
The south-western winds continued to blow without intermission, and drove us, much against my inclination, far to the eastward, towards the coast of Africa. One or two attempts were made to go upon the western tack; but this could not be done with any advantage until the 2nd of September, when we were in latitude 3 deg. 50' north, and longitude 111/4 deg. west. The wind had veered gradually round, from south-west to south, as we approached the African coast, to the direction of which it kept at nearly a right angle. I had not fully adverted to the probability, that the winds blowing upon this coast would prevail to a greater extent at this season than at any other time of the year; otherwise, as I wished to avoid Africa, I should have passed some degrees to the westward of the Cape-Verde Islands, and probably have carried the north-east trade to the 12th, or perhaps to the 10th degree of north latitude; and in 8 deg., or at furthest in 6 deg., the south-east trade might have been expected.
Captain Cook, in his second voyage, experienced the same south-western winds, and was carried so far eastward, that he crossed the equator in longitude 8 deg. west. Monsieur de la Perouse also experienced them, and both were here at the same season with ourselves; that is, in the months of August and September, when the African continent had received its greatest degree of heat.
Although I preferred to avoid Africa, it is by no means certain that a good passage to the Cape of Good Hope may not be made, especially at this season, by steering round the Bight of Benin with the south-west and south winds. It is probable, that on approaching the meridian of Greenwich the wind would be found to return to the south-west, and perhaps more westward, and enable a ship to reach the 10th degree of south latitude before meeting the south-east trade; in which case, the circuit to be made before attaining the western winds beyond the southern tropic, would be much shortened. The East-India-Company's ships bound to St. Helena, do, I believe, now generally follow that route.
The leakiness of the ship increased with the continuance of the south-west winds; and at the end of a week, amounted to five inches of water an hour. It seemed, however, that the leaks were mostly above the water's edge, for on tacking to the westward they were diminished to two inches. This working of the oakum out of the seams indicated a degree of weakness which, in a ship destined to encounter every hazard, could not be contemplated without uneasiness. The very large ports, formerly cut in the sides to receive thirty-two-pound carronades, joined to what I had been able to collect from the dock yard officers, had given me an unfavourable opinion of her strength; and this was now but too much confirmed. Should it be asked, why representations were not made, and a stronger vessel procured? I answer, that the exigencies of the navy were such at that time, that I was given to understand no better ship could be spared from the service; and my anxiety to complete the investigation of the coasts of Terra Australis did not admit of refusing the one offered.
THURSDAY 3 SEPTEMBER 1801
The wind was at south when we tacked to the westward; but it shortly veered to south-by-east, and as far as south-east-by-south, which enabled me to look up for the small Isle Sable, or St. Paul, said to lie in 0 deg. 25' south, and about 181/2 deg. west. I was desirous of ascertaining the true position of this, and of some other small islands, laid down in the neighbourhood of the equator. They are placed so much in the tracks, both of outward and homeward bound ships, that it was not improbable some one of the vessels missed at different times, might have suffered shipwreck upon them; and the hope that we might be the happy means of restoring to their country and friends some unfortunate fellow creatures, perhaps countrymen, was an additional incitement to look after them.
MONDAY 7 SEPTEMBER 1801
On the 7th, our latitude was 0 deg. 43' north, and we expected to cross the equator some time in the following night. It was a part of my plan for preserving the health of the people, to promote active amusements amongst them, so long as it did not interfere with the duties of the ship; and therefore the ancient ceremonies used on this occasion, were allowed to be performed this evening; and the ship being previously put under snug sail, the seamen were furnished with the means, and the permission, to conclude the day with merriment. At noon next day, the latitude was 0 deg. 17' south, and longitude 17 deg. 7' west; so that the line had been crossed in nearly 17 deg., about seven in the morning [TUESDAY 8 SEPTEMBER].
From the longitude of 11 deg., we had been constantly attended by that species of the pelican called man-of-war bird by our seamen, and fregate by the French; but not one of them was to be seen at this time, although we were drawing near to the supposed situation of St. Paul. At four in the afternoon, our latitude was judged to be 0 deg. 29' south; and the course then steered was west, by compass, for a current of ten miles to the north had fully counteracted the western variation on the two preceding days. On the 9th [WEDNESDAY], the latitude was 0 deg. 43' south, and longitude 18 deg. 35'. We ran northward four hours, finding the current had not prevailed as before; and then steered in the parallel of the island. Next day at noon [THURSDAY 10 SEPTEMBER], our situation was in 0 deg. 22' south and 20 deg. 5' west; and seeing no land, nor any signs of being in its neighbourhood, I gave up the search after the island, and hauled south-westward on our way to the Cape of Good Hope.
In the morning, I had observed the variation with Walker's meridional compass, when the ship's head was W. by N. (magnetic); upon the binnacle it gave 14 deg. 30', and on the booms 13' 0' west. Thus the difference, arising from a change of place in the compass, appeared to diminish sensibly as we approached the magnetic equator. The true variation I judge to have been 13 deg. 11' west.
During the two nights of our search for St. Paul's, the quantity of sail was so reduced that not more than ten or twelve leagues should be passed between dusk and daylight; by which means the view astern, in the morning, nearly reached to the horizon of the preceding evening, and any thing, a little elevated above the surface of the water, could scarcely escape being seen from the mast head, more especially as we were fortunate in having distinct views towards each setting and rising sun. The look-out, also, was particularly attended to; for at this time was commenced the system which, in all similar cases, I intended to pursue throughout the voyage. A part of this plan was an order to the three warrant officers to take charge of the look-out betwixt dark and daylight, and to be answerable for the vigilance with which it should be executed, both in their own persons, and in those who were placed upon the same duty under them. The leisure usually enjoyed by this class of officers, particularly by the gunner and carpenter, I conceived to admit of this abridgment, without injury to their ordinary sea duties.
I had twice before crossed the equator, at the respective distances of twenty-six and seventy-three miles to the west of where our search for the Isle of St. Paul ceased; and Mr. Thistle, the master, had crossed the parallel of 25' south, in longitude 22 deg. 12', a few months before; indeed if the Isle had existed between the longitudes of 20 deg. and 25 deg., it must have been repeatedly seen. I therefore think it may be asserted, that there is no land between 17 deg. and 25 deg. west, either in, or about the latitude of 25' south. The track of Mons. de la Perouse cuts that parallel in longitude 16 deg.; and he saw no other marks of the vicinity of land than the man-of-war birds which had followed him for several days. If the presence of these birds be any indication of land, I should suppose that there was some lying between the 11th and 16th degrees of west longitude; and if such an island as St. Paul exist, it will probably be found within those limits.
Having lost all hope of finding this island, I could have wished to recross the equator and run in the latitude of 55' north; in which parallel the isle Pennedo de St. Pedro, sometimes also called St. Paul, is said to be situate. In Arrowsmith's general chart, it is marked in 24 deg. west longitude, whilst another authority places it to the west of 27 deg.,* but I considered that the search might carry me as far as 29 deg., and perhaps further; and my orders being silent with respect to these islands, I did not think myself authorized to thus occupy so much time; and we therefore hauled to the south-westward on the afternoon of the 10th, as before mentioned. On the following day [FRIDAY SEPTEMBER 11], a gannet was seen, which seemed to imply that our situation of 1 3/4 deg. south, and 211/2 deg. west, was not far removed from some island or rock; for I do not recollect to have seen this bird at a greater distance from land than thirty leagues.
[* Voyage of La Perouse, page 50 of the London translation. I am lately informed, that Pennedo de St. Pedro lies in latitude 0 deg. 55' north, and longitude 27 deg. 0' west; that it makes like four sail of ships, and is covered with birds, but affords no water.]
The trade wind varied from south-south-east to east-south-east, and commonly blew fresh, with frequent squalls. The swell from the southward, with which these winds were for some days accompanied, caused the ship to work so much, that she soon let in as great a quantity of water on this tack, as she before had done on the other; I therefore judged it advisable to alter the plan of keeping within seven points of the wind, and to go with it upon the beam; and also to put in practice every means of lightening the upper works, for they seemed to be very inadequate to support the weight with which they had been unavoidably loaded. Two eighteen-pound carronades, stern chacers, were taken off the upper deck and struck into the hold; the spare rudder, and a variety of other things which a want of room had obliged us to stow in the main and mizen channels, were taken within board; and every exterior weight concentrated as much as possible. After this was done, the tremulous motion caused by every blow of the sea, exciting a sensation as if the timbers of the ship were elastic, was considerably diminished; and the quantity of water admitted by the leaks was also somewhat reduced.
SUNDAY 13 SEPTEMBER 1801
On the 13th, in latitude 4 deg. 44' south and longitude 23 deg. 17' west, a swallow, a gannet, and two sheerwaters were seen; and from six to eight in the evening, the officer of the watch and myself thought the water to be much smoother than before, or than it was afterward. Had it been in an unknown sea, I should have been persuaded that some island, or shoal, lay at no great distance to the south-eastward of our situation at that time.
SUNDAY 20 SEPTEMBER 1801
The trade wind continued, with some little variety in its direction, to blow fresh until the 20th, when it became light, and sometimes calm. We were then approaching the small island Trinidad. Many gannets were seen at twenty-four leagues off, but none at a greater distance. On the 23rd [WEDNESDAY], the island was in sight; and at noon, when our latitude was 20 deg. 1' south, and longitude 29 deg. 13' west, a peaked hummock near the eastern extremity bore S. 25 deg. W., nine or ten leagues. The western extremity bore S. 29 deg. W., and at first appeared to be a bluff head; but it afterwards assumed the form of a conical rock, and was, in all probability, the Nine Pin of captain D'Auvergne's chart. One of the rocks called Martin Vas, was visible from the main top, and angled 49 deg. 43' to the left of the peaked hummock; its bearing was consequently very near S. 25 deg. E.
Mons. de la Perouse, who sent a boat on shore to Trinidad, lays down the latitude of the south-east point at 20 deg. 31' south, and longitude from lunar observations, 28 deg. 37' west of Greenwich. The latitude appeared to agree with our observations; but in the longitude there is some difference. According to Earnshaw's two time keepers, No. 465 and 543, which kept better rates than the remaining four, the longitude of the Nine Pin is 29 deg. 251/2' west; which being reduced to the south-east point, will place it in 29 deg. 23', or 46' west of the French navigator.* The longitude in captain D'Auvergne's plan of Trinidad, constructed 1782, is 29 deg. 55', or 32' still further west. From two sets of distances of the star Altair to the west, and two of Aldebaran east of the moon, I made the longitude of the south-east point to be 29 deg. 19' west; the difference from the time keepers, which I consider to have given the best longitude, being no more than 4'.
[* The error of No. 465 was found, at the Cape of Good Hope, to be 10' 57", 2 to the east, and of No. 543, to be 39' 21", 5 east, contracted in 96 days upon their English rates. To obtain the above longitude, a proportional part of these errors according to the number of days, has been applied to the keepers; and the difference between them is then no more than 2".]
THURSDAY 24 SEPTEMBER 1801
Azimuths taken upon the binnacle in the morning, with three compasses, and the ship's head at S. W. by S., gave variation 3 deg. 54'; and in the evening, at S. W., 3 deg. 50'; but next morning, when Trinidad was just disappearing from the deck in the N. 60 deg. E., other azimuths then showed the variation to be 1 deg. 35' west, the ship's head being S. S. W.; it therefore appears, that there is a difference off the north, and off the south-west sides of the island. From the first observations I deduce the true variation to be 4 deg. 14' west, and from the last 1 deg. 50' west. Captain D'Auvergne marks the variation 0 deg. 45' west, in 1782; but under what circumstances it was ascertained, does not appear.
TUESDAY 29 SEPTEMBER 1801
The trade wind having again arisen from east-south-east, we were enabled to make between eighty and ninety miles a day. It afterwards veered gradually round, by the north-east and north, to the westward, and blew fresh; so that on the 29th, our latitude was 31 deg. 2' and longitude 26 deg. 0' west. This was 17' to the south, and about 6 deg. west of the situation usually assigned to Saxemberg; an island which has been frequently sought by the East-India, and other ships, in the place which it still occupies in the charts; and not finding it there, they have run a few degrees to the eastward, in the same parallel, but always without success. The opportunity which presented itself of now adding 6 deg. of longitude to the examined space, and on the opposite side, I should have thought myself culpable in neglecting; and therefore, having placed the ship in the supposed parallel of the island, we steered due east for it; adopting the same regulations for the look-out at night, as when searching for St. Paul's.
We had seen an unusual number of pintado and sooty petrels on the preceding afternoon, as also of a brown bird, apparently one of the sea-swallow tribe, having a white belly and the form and size of a woodcock; and this evening it was reported to me from the mast head, and confirmed by others on deck, that a turtle was seen lying upon the water. These indications of land gave me some hope that the long lost Saxemberg might be brought to light. On the following noon [WEDNESDAY 30 SEPTEMBER], the observed latitude was 30 deg. 41' and longitude 22 deg. 46'; and nothing further had transpired to betoken the vicinity of land. Next day [THURSDAY 1 OCTOBER], our observations gave 30 deg. 34' south, and 20 deg. 28' west; and I then steered east-south-east, a course which should have taken us almost directly over the supposed situation of Saxemberg, if the same current of 11' north had prevailed, as on the preceding day. But this not proving to be the case, our track lay a few miles to the south; though sufficiently near for us to be satisfied of the non-existence of the island in the place assigned to it, if that could any longer admit of a doubt.*
[* At the Cape of Good Hope, in 1810, His Excellency the Earl of Caledon favoured me with the following extract from the log book of the sloop Columbus—Long, master; returning to the Cape from the coast of Brazil.
"September 22, 1809, at five p.m., saw the island of Saxonburg, bearing E. S. E., first about 41 leagues distant: clear weather. Steered for the said island, and found it to be in the latitude of 30 deg. 18' south, longitude 28 deg. 20' west, or thereabout.
"The island of Saxonburg is about four leagues in length, N. W. and S. E, and about 21/2 miles in breadth. The N. W. end is a high bluff of about 70 feet, perpendicular form, and runs along to the south-east about 8 miles. You will see trees at about a mile and a half distance, and a sandy beach."
The situation of Saxemberg in the common tables and charts, was 30 deg. 45' south and 19 deg. 40' west, almost 9 deg. of longitude too little; and therefore it is not surprising that ships have missed it. At the time so many birds were seen, on the 28th, the Investigator was not more than eighty miles from the position of the island, as above given from Mr. Long.]
SUNDAY 4 OCTOBER 1801
The fresh western winds continued, with short intervals of calm, as far as the latitude 33 deg. 23', and longitude 13 deg. 0' west; when they died away, and a breeze sprung up from the eastward. With this wind we could do little more than look up for the isles of Tristan d'Acunha, whose bearing was then S. 16 deg. E., and distance seventy-seven leagues. From the description given by sir Erasmus Gower* of the anchorage, and the convenience with which water may be obtained, and his account of the animals which resort there, I should not have considered it to be lost time, had the wind made it advisable to put in at Tristan d'Acunha, for a few days; but it veered round to the north-west, on the [TUESDAY] 6th. and we resumed our former course to the Cape of Good Hope.

WEDNESDAY 14 OCTOBER 1801
In the morning of the 14th, the variation by mean of amplitude and azimuth, was 25 deg. 10' west; the ship's head being E. by S., and our latitude 35 deg. 4' south, and longitude 12 deg. 50' east. It is worthy of being mentioned, that in the year 1797, and near the same place, I observed the variation to be 19 deg. 40' west, on board His Majesty's ship Reliance; and as the compass was upon the binnacle in both cases, the sole cause to which I can attribute this great difference is, that the ship's head was west, instead of E. by S. The true variation could not be far from the mean of the two observations, since it was 26 deg. at the Cape of Good Hope. In the English Channel, the compass on the binnacle had shown nearly 4 deg. too much west variation, when the ship's head was at west; but here, it gives at least 2 deg. too much, with the head in an opposite direction! This difference in the two hemispheres merits particular notice; it is part of a series of apparent anomalies in the compass which have hitherto remained unaccounted for; but which seem reducible to one general cause, as I have attempted to show in the Appendix No. II. to the second volume.
FRIDAY 16 OCTOBER 1801
At daybreak of the 16th, we expected to see the high land of the Cape; but the weather being hazy, it could not be distinguished until eight o'clock, when it bore north-east, eight leagues; being three leagues more than Earnshaw's pocket time keeper, in which we had most confidence, led us to expect, and four miles less than was given by my uncorrected lunar observations of the 14th p.m., brought forward by the time keeper.
At this time we had not a single person in the sick list, both officers and men being fully in as good health, as when we sailed from Spithead. I had begun very early to put in execution the beneficial plan, first practised and made known by the great captain Cook. It was in the standing orders of the ship, that on every fine day the deck below and the cockpits should be cleared, washed, aired with stoves, and sprinkled with vinegar. On wet and dull days they were cleaned and aired, without washing. Care was taken to prevent the people from sleeping upon deck, or lying down in their wet clothes; and once in every fortnight or three weeks, as circumstances permitted, their beds, and the contents of their chests and bags, were opened out and exposed to the sun and air. On the Sunday and Thursday mornings, the ship's company was mustered, and every man appeared clean shaved and dressed; and when the evenings were fine, the drum and fife announced the fore castle to be the scene of dancing; nor did I discourage other playful amusements which might occasionally be more to the taste of the sailors, and were not unseasonable.
Within the tropics, lime juice and sugar were made to suffice as antiscorbutics; on reaching a higher latitude, sour krout and vinegar were substituted; the essence of malt was reserved for the passage to New Holland, and for future occasions. On consulting with the surgeon, I had thought it expedient to make some slight changes in the issuing of the provisions. Oatmeal was boiled for breakfast four days in the week, instead of three; and when rice was issued, after the expenditure of the cheese, it was boiled on the other three days. Pease soup was prepared for dinner four days in the week, as usual; and at other times, two ounces of portable broth, in cakes, to each man, with such additions of onions, pepper, etc. as the different messes possessed, made a comfortable addition to their salt meat. And neither in this passage, nor, I may add, in any subsequent part of the voyage, were the officers or people restricted to any allowance of fresh water. They drank freely at the scuttled cask, and took away, under the inspection of the officer of the watch, all that was requisite for culinary purposes; and very frequently two casks of water in the week were given for washing their clothes.
With these regulations, joined to a due enforcement of discipline, I had the satisfaction to see my people orderly and full of zeal for the service in which we were engaged; and in such a state of health, that no delay at the Cape was required beyond the necessary refitment of the ship, and I still hoped to save a good part of the summer season upon the south coast of Terra Australis.
[CAPE OF GOOD HOPE. FALSE BAY]
The usual time for His Majesty's ships to leave False Bay and go round to Table Bay, I found to be the latter end of September; but being then unacquainted with the precise time, and knowing of the loss of the Sceptre in Table Bay, on November 5, from a heavy gale at north-west, I determined to go into False Bay; unless we should get previous information that it had been quitted by the squadron. At noon, the extremes of the land bore N. by W. 1/2 W. and E. 1/2 N. The Cape Point bore north, three leagues; and our observed latitude being 34 deg. 32', showed the Requisite Tables to be erroneous in the position of this point; but that 34 deg. 23', as assigned to it by captain King, was correct.*
[* See Cook's third Voyage, Vol. III. page 484.]
At one o'clock we hauled round the rocks which lie off the Cape Point, and steered into False Bay. Near these rocks were two whales; and one or more of what seamen call thrashers were engaged in a furious combat with them, at a less distance than half a mile from the ship. The sinewy strength of the thrasher must be very great; for besides raising his tail high out of the water to beat the adversary, he occasionally threw the whole of his vast body several feet above the surface, apparently to fall upon him with greater force. Their struggles covered the sea with foam for many fathoms round.
At three o'clock we got sight of the squadron lying in Simon's Bay. It consisted of His Majesty's ships Lancaster, Jupiter, Diomede, Imperieuse, Hindoostan, Rattlesnake, and Euphrosyne, under the command of vice-admiral sir Roger Curtis, Bart. The master of the Lancaster came on board to pilot the ship to a proper berth, and I went on shore to wait upon the vice-admiral. On showing my orders, and presenting an account of the supplies and the work requisite to put the Investigator in the same state as on leaving England, I found that the naval magazines could furnish only some part, and that many articles, especially biscuit, were not to be obtained; but with great consideration for the service on which I was sent out, the commander in chief ordered every request to be granted either in the articles specified, or by substitution; and a thorough caulking, both within and without side of the ship, being the work most essential to be done, a gang of caulkers, collected from the squadron, was sent on board on the following morning.
SATURDAY 17 OCTOBER 1801
The water which is conducted in pipes to the wharf, for the convenience of shipping, was said not to keep well at sea; and the master of the Lancaster, from whom this information was obtained, recommended, as much superior, that which drains through the sand, from the hills on the north side of Simon's Bay. I went, accordingly, to make an examination; and found that by sinking a cask in the sand, with the head out and the upper hoops taken off, the water drained through the spaces between the staves, sufficiently fast for our purpose. This plan was therefore adopted; and the watering of the ship immediately commenced.
Having seen this, and some other duties set forward under the proper officers, I accompanied Mr. Crosley, the astronomer, in search of a place where the observatory and tents could be conveniently set up. The situation chosen was near a small rill on the south side of the bay, about three-hundred yards from the magazine; and the permission of the military commandant being obtained, two tents, the observatory, and astronomical instruments were landed in the afternoon, with a guard of marines. The whole was placed under the charge of Mr. Flinders, the second lieutenant, who was also to act as an assistant in making and calculating the observations, for which he was qualified. The situation of the tents was tolerably well sheltered from the south-eastern gales, which begin to prevail at this season of the year; but the quantity of sand put in motion by every breeze, was a great molestation, and proved injurious to the instruments. Besides this inconvenience, there was another attached to the situation which had not been foreseen. The road from Simon's Town to a place called the Company's garden, led close past the observatory; and this was the sole ride or walk in the neighbourhood, which the inhabitants and the gentlemen belonging to the ships in the bay could enjoy. From those of the first rank, who took their morning's ride, to the sailor who staggered past on a Sunday, and even the slave with his bundle of fire wood, all stopped at the observatory to see what was going on. Ramsden's universal theodolite, set up for the purpose of observing transits, excited its share of attention from the curious. Some wanted information, some amusement, and all would have liked to see how the sun appeared through the telescope.
By the end of October, our provisions and stores were received; the sails had been examined and repaired on board the Lancaster, and were rebent; and the caulkers having completed their work, the ship was fresh painted. Being anxious to commence the investigation of the coasts of Terra Australis, the stripping of the masts and reparation of the rigging were deferred to King George's Sound, and no more was done at the ship than necessity required; for I preferred passing the time necessary to a complete re-equipment in a port where astronomical observations and surveys could be at the same time usefully carried on, and the naturalists employ themselves in a field almost unexplored, rather than in a bay already well known, and where the surrounding country had been so often traversed.
Mr. Crosley had been frequently unwell during the passage from Madeira; and after trying the effect of a few days on shore, he decided to remain at the Cape of Good Hope, and relinquish the expedition. The instruments supplied by the Board of Longitude he agreed to leave in my care; after having consulted with the commander in chief upon the subject, and received his approbation. The loss of the astronomer was severely felt by me, both from being deprived in the surveys of his more accurate observations, and from being called upon to supply his place so far as was in my power. The duties of commander joined to the occupation of surveyor, left little time for other employment; but through an increase of effort, and with the assistance of my officers, I hoped to carry on the surveys and fulfil the most essential parts of the instructions from the Board of Longitude, at the same time. Of these instructions, Mr. Crosley permitted me to take a copy.
SUNDAY 1 NOVEMBER 1801
The rates of going with mean solar time of the four time keepers committed to my charge, were deduced by Mr. Crosley from three days observation of equal altitudes, with a sextant and quick-silver horizon, between the 21st and 27th of October. These rates, which he left with me, I extended to November 1, by equal altitudes taken on that day; and their respective errors were deduced by allowing 1h 13' 40.47" to be the longitude in time of Simon's Bay. *
[* In 1763, Mr. Mason determined the longitude of his observatory in Cape Town, from the transit of Venus, to be 18 deg. 23' 7" east; and the difference of longitude from thence to Simon's Bay, by the Dutch survey, is 2' 00" east.]
Earnshaw's No. 543, slower than mean Greenwich time at noon h ' " " there Nov. 1, 0 14 35.33 and losing 5.33 No. 520, 34 16.62 15.84 Arnold's No. 176, 50 59.29 8.96 No. 82 ———— ——- No. 1736, watch, faster 21 20.03 17.27
The watch was intended to be taken up rivers, and to such places as the ship did not go; and in order to gain some knowledge of its probable performance, I wore it five days in the pocket. Its rate of losing during that time, was from 11.59" to 8.79" per day; so that upon the average, it lost 7" less in the pocket than when in a fixed situation; for the above rate of 17.27" was what it kept in the box, during the last three days. Arnold's No. 89, altered its rate on the last day, from 2.98" to 1' 18.68", without any apparent cause; no rate could therefore be fixed for it, with any probability of its being kept. Of the excellent watch No. 465 of Earnshaw, being Mr. Crosley's private property, we were deprived at the same time with the astronomer; he also took with him the reflecting circle, No. 74 of Troughton, both of which I considered to be an addition to our loss.
So soon as the corresponding altitudes of Sunday afternoon were obtained, I took on board the time keepers and instruments, with the tents and observatory. The ship was then ready for sea; but the wind blew a gale from the south-eastward, which continued until Tuesday [3 NOVEMBER 1801]. It then fell calm, and we unmoored; but before getting under way, the same wind again set in, and obliged us to drop a second anchor.
Through the kind attention of sir Roger Curtis, the commander in chief, the state of the ship and our provisions and stores were as complete as when leaving Spithead. The ship's company had been regularly served with fresh meat every day, beef and mutton alternately; vegetables were not to be purchased, but we several times received small quantities, with oranges and lemons, from the naval hospital in Cape Town; and a proportion of these for a week, with a few days fresh meat, were carried to sea. Two of my ship's company, whose dispositions required more severity in reducing to good order than I wished to exercise in a service of this nature, were exchanged by the vice-admiral; as also two others, who from want of sufficient strength, were not proper for so long a voyage. In lieu of these, I received four men of good character from the flag ship, who made pressing application to go upon a voyage of discovery. Mr. Nathaniel Bell, one of the young gentlemen of the quarter deck, having expressed a wish to return to England, he was discharged; and Mr. Denis Lacey, midshipman of the Lancaster, received in his place.
Simon's Bay is known to be a large and well-sheltered cove, in the north-western part of the sound, called False Bay. Since the loss of the Sceptre in Table Bay, it has been more frequented than formerly; and I found it to be a prevailing sentiment, that were it not for the advantages of Cape Town, Simon's Bay would, in every respect, be preferable for the royal dockyard, and the equipment of His Majesty's ships. It was remarked to me by an officer of discernment, captain of the flag ship, that instances of vessels being driven from their anchors by winds blowing into Simon's Bay, were exceedingly rare. He had observed that the strain upon the cables with these winds, was much less than with those of equal strength blowing off the land; and he accounted for it from the water thrown into the bay by sea winds, rebounding from the shore and forming what is called an under-tow, which tended to keep a ship up to her anchors. This takes place in Simon's Bay, with the south-east winds, but not in Table Bay with those from the north-west, which blow into it; owing, in part, to the distance at which ships there ride from the land, and apparently, also, from the under-tow passing out on the eastern side of the bay, clear of the anchoring ground.
The Cape of Good Hope cannot now be supposed to furnish much of novelty in the department of natural history, especially to transient visitors; but it still continues to afford much amusement and instruction to English botanists. It did so to our gentlemen, who were almost constantly on shore upon the search; and their collections, intended for examination on the next passage, were tolerably ample. They were sufficiently orthodox to walk many miles for the purpose of botanising upon the celebrated Table Mountain; for what disciple of Linnaeus could otherwise conscientiously quit the Cape of Good Hope? In taking so early a departure, though it were to proceed to the almost untrodden, and not less ample field of botany, New Holland, I had to engage with the counter wishes of my scientific associates; so much were they delighted to find the richest treasures of the English green house, profusely scattered over the sides and summits of these barren hills.

[TOWARDS NEW HOLLAND]
WEDNESDAY 4 NOVEMBER 1801
At daybreak of November 4, a light breeze from the eastward enabled me to quit Simon's Bay, after a stoppage of eighteen days. The high land of Great Smit's Winkel afterwards becalmed the sails; and we were no further advanced, at noon, than to have the Cape Point bearing south-west, at the distance of two or three leagues. On receiving the breeze, which came from the south-south-west, we stretched towards Cape Agulhas, veering ship at eleven at night, on coming into 50 fathoms. This wind died away in the morning, and remained calm till noon; the Cape Point then bore N. W. 3/4 N., Cape False N. 3/4 E., and our latitude was 34 deg. 36'. Near this situation, the bottom is a greenish mud, at the depth of 78 fathoms.
The report of the guns fired by the squadron in Simon's Bay, to commemorate the escape from gunpowder treason, was distinctly heard at one o'clock, when we were occupied in making sail to a fine breeze which had sprung up from the south-westward. At six in the evening, it blew fresh with cloudy weather; the extremes of the land bore from N. 20 deg. W to W. 58 deg. E., and we took our departure for New Holland.
Lieutenant Flinders observed azimuths this evening from the binnacle with two compasses; the ship's head was south (magnetic), and the variation found to be 26 deg. 13' west; and in default of observations on shore, I consider this to have been the true variation at the Cape of Good Hope in 1801.
During our run across the Agulhas Bank, I did not find any current setting to the westward; but in the five days taken to reach the latitude 36 deg. 30' and longitude 33 deg. 38', [TUESDAY 10 NOVEMBER 1801] the ship was set 59' to the north of the reckoning. The swell which followed after the ship probably counteracted the effect of the usual westwardly current; and indeed it must have done something more, if our log were correct, since the longitude by time keepers was then 30' ahead of account.
I considered the parallel Of 37 deg. south, at this season of the year, to be sufficiently distant from the verge of the south-east trade to insure a continuance of western winds; and to be far enough to the north, to avoid the gales incident to high latitudes. Having made this passage three times before, I was satisfied of the impropriety of running in a high southern latitude, particularly when the sun is in the other hemisphere, and there is nothing else in view than to make a good passage; not only from the winds there being often stronger than desired, but because they will not blow so steadily from the westward. In the latitude of 42 deg., I have experienced heavy gales from the north, and from the south, and even from the eastward, in the months of June and July; allowances for lee way were also frequent in that passage, and light winds or calms not uncommon. The parallel of 42 deg. seems to be a very proper one, when the sun is in his highest south declination, and from that time until the middle of February; but in the opposite months of the year, I should prefer to run down my easting two or three degrees even to the northward of what was now chosen for the Investigator.
It may not be improper to anticipate upon the voyage so far as to state what was the result of keeping in the parallel of 37 deg., in the month of November. From the Cape of Good Hope to the island Amsterdam, the winds were never so strong as to reduce the Investigator to close-reefed top sails; and on the other hand, the calms amounted to no more than seven hours in nineteen days. The average distance on the log board upon direct courses, for we had no foul winds, was a hundred and forty miles per day; and the Investigator was not a frigate, but a collier-built ship, and deeply laden. In the following twelve days run, from Amsterdam to the south-west cape of New Holland, the same winds attended us; and a hundred and fifty eight miles per day was the average distance, without lee way or calm.
THURSDAY 12 NOVEMBER 1801
On the 12th, I took the opportunity of light winds to send down a bucket, fitted with valves to bring up water from a depth; but having no thermometer of a proper size to go into the bucket, I could only immerse one after the water was brought up. In this imperfect way, the temperature at 150 fathoms depth was found to be 63 deg.,1, differing very little from that of the water at the surface, which was 63 deg.,8. In the air, the thermometer stood at 63 deg.,6. The specific gravity of the water brought up was afterwards tried at King George's Sound, and proved, at the temperature of 69 deg., to be 1,026, taking that of the crystal-glass bulb, with which the experiment was made, at 3,150; and the specific gravity of the surface water, taken up at the same time, was exactly the same. The latitude of our situation was 36 deg. 36' south, and longitude 38 deg. 23' east. The mean inclination of the dipping needle, placed upon the cabin table, was 58 deg. 4' of the south end; and the variation, by mean of azimuths on the preceding evening and amplitude this morning, taken on the binnacle when the ships head was S. E. by E., magnetic, was 31 deg. 47'; but the true variation, or such as would have been obtained with the head at north, or south, I consider to have been 29 deg. 22' west. |
