[Land upon Possession Island.]
Wednesday, 22nd. Gentle breezes at East by South and clear weather. We had not steer'd above 3 or 4 Miles along shore to the westward before we discover'd the land ahead to be Islands detached by several Channels from the main land; upon this we brought too to Wait for the Yawl, and called the other Boats on board, and after giving them proper instructions, sent them away again to lead us thro' the Channell next the Main, and as soon as the Yawl was on board made sail after them with the Ship. Soon after we discover'd rocks and Shoals in this Channell, upon which I made the Signal for the boats to lead thro' the next Channel to the Northward* (* This led to Endeavour Strait, but the recognised track is the channel farther north.) laying between the Islands, which they accordingly did, we following with the Ship, and had not less than 5 fathoms; and this in the narrowest part of the Channel, which was about a Mile and a 1/2 broad from Island to Island. At 4 o'Clock we Anchor'd about a Mile and a 1/2 or 2 Miles within the Entrance in 6 1/2 fathoms, clear ground, distance from the Islands on each side of us one Mile, the Main land extending away to the South-West; the farthest point of which we could see bore from us South 48 degrees West, and the Southermost point of the Islands, on the North-West side of the Passage, bore South 76 degrees West. Between these 2 points we could see no land, so that we were in great hopes that we had at last found out a Passage into the Indian seas; but in order to be better informed I landed with a party of men, accompanied by Mr. Banks and Dr. Solander, upon the Islands which lies at the South-East point of the Passage. Before and after we Anchor'd we saw a Number of People upon this Island, Arm'd in the same manner as all the others we have seen, Except one man, who had a bow and a bundle of Arrows, the first we have seen upon this Coast. From the appearance of the people we expected they would have opposed our landing; but as we approached the shore they all made off, and left us in peaceable possession of as much of the Island as served our purpose. After landing I went upon the highest hill, which, however, was of no great height, yet no less than twice or thrice the height of the Ship's Mastheads; but I could see from it no land between South-West and West-South-West, so that I did not doubt but there was a passage. I could see plainly that the lands laying to the North-West of this passage were compos'd of a number of Islands of Various extent, both for height and Circuit, ranged one behind another as far to the Northward and Westward as I could see, which could not be less than 12 or 14 Leagues.
Having satisfied myself of the great Probability of a passage, thro' which I intend going with the Ship, and therefore may land no more upon this Eastern coast of New Holland, and on the Western side I can make no new discovery, the honour of which belongs to the Dutch Navigators, but the Eastern Coast from the Latitude of 38 degrees South down to this place, I am confident, was never seen or Visited by any European before us; and notwithstanding I had in the Name of his Majesty taken possession of several places upon this Coast, I now once More hoisted English Colours, and in the Name of His Majesty King George the Third took possession of the whole Eastern coast from the above Latitude down to this place by the Name of New Wales,* (* The Admiralty copy, as well as that belonging to Her Majesty, calls it New South Wales. The island where the ceremony was performed was named on Cook's chart Possession Island, and is still so called.) together with all the Bays, Harbours, Rivers, and Islands, situated upon the said Coast; after which we fired 3 Volleys of small Arms, which were answer'd by the like number from the Ship.
This done, we set out for the Ship, but were some time in getting on board on account of a very Rapid Ebb Tide, which set North-East out of the Passage. Ever since we came in amongst the Shoals this last time we have found a Moderate Tide; the flood setting to the North-West and Ebb to the South-East; at this place is high water at full and change of the moon, about 1 or 2 o'Clock, and riseth and falleth upon a perpendicular about 10 or 12 feet. We saw upon all the Adjacent Lands and Islands a great number of smokes--a certain sign that they are inhabited--and we have daily seen smokes on every part of the Coast we have lately been upon. Between 7 and 8 o'Clock a.m. we saw several naked people, all or most of them Women, down upon the beach picking up Shells, etc.; they had not a single rag of any kind of Cloathing upon them, and both these and those we saw yesterday were in every respect the same sort of People we have seen everywhere upon the Coast. 2 or 3 of the Men we saw Yesterday had on pretty large breast plates, which we supposed were made of pearl Oyster Shells; this was a thing, as well as the Bow and Arrows, we had not seen before. At low water, which hapned about 10 o'Clock, we got under sail, and stood to the South-West, with a light breeze at East, which afterwards veer'd to North by East, having the Pinnace ahead; depth of Water from 6 to 10 fathoms, except in one place, were we passed over a Bank of 5 fathoms. At Noon Possession Island, at the South-East entrance of the Passage, bore North 53 degrees East, distant 4 Leagues; the Western extream of the Main land in sight South 43 degrees West, distant 4 or 5 Leagues, being all exceeding low. The South-West point of the largest Island* (* Prince of Wales Island.) on the North-West side of the passage bore North 71 degrees West, distant 8 Miles; this point I named Cape Cornwall (Latitude 10 degrees 43 minutes South, Longitude 218 degrees 59 minutes West),* (* This longitude is 70 minutes too far west, and one of the worst given in the Journal. There were no observations, and the dead reckoning among the shoals was difficult to keep.) and some low Islands lying about the Middle of the Passage, which I called Wallace's Isles, bore West by South 1/2 South, distance about 2 Leagues. Our Latitude by Observation was 10 degrees 46 minutes South.
[In Endeavour Strait, Torres Strait.]
Thursday, 23rd. In the P.M. had little wind and Variable, with which and the Tide of Flood we keept advancing to the West-North-West; depth of Water 8, 7, and 5 fathoms. At 1/2 past 1 the pinnace, which was ahead, made the Signal for Shoal Water, upon which we Tackt and sent away the Yawl to sound also, and then Tack'd again, and stood after them with the Ship; 2 hours after this they both at once made the Signal for having Shoal water. I was afraid to stand on for fear of running aground at that time of the Tide, and therefore came to an Anchor in 1/4 less 7 fathoms, sandy ground. Wallice's Islands bore South by West 1/2 West, distant 5 or 6 Miles, the Islands to the Northward extending from North 73 degrees East to North 10 degrees East, and a small island* (* Booby Island.) just in sight bearing North-West 1/2 West. Here we found the flood Tide set to the Westward and Ebb to the Contrary. After we had come to Anchor I sent away the Master with the Long boat to sound, who, upon his return in the evening, reported that there was a bank stretching North and South, upon which were 3 fathoms Water, and behind it 7 fathoms. We had it Calm all Night and until 9 in the morning, at which time we weigh'd, with a light breeze at South-South-East, and steer'd North-West by West for the Small Island above mentioned, having first sent the Boats ahead to sound; depth of Water 8, 7, 6, 5, 4, and 3 fathoms when upon the Bank,* (* The Endeavour Strait is now little used, on account of this great bank, which nearly bars its western part. There is, however, deeper water than Cook found, a few miles to the southward; but it is just the difficulty of finding this narrow pass, so far from land, and the fact that there is a deep though narrow channel north of Prince of Wales Island, that has caused it to be abandoned. The passage of Torres Strait is, however, still an anxious bit of navigation.) it being now the last Quarter Ebb. At this time the most Northermost Islands we had in sight bore North 9 degrees East; the South-West point of the largest Islands on the North-West side of the Passage, which I named Cape Cornwall, bore East; distant 3 Leagues. This bank, at least so much as we sounded, extends nearly North and South, how far I cannot say; its breadth, however, is not more than 1/4 or at most 1/2 a Mile. Being over the Bank, we deepned our water to a 1/4 less 7 fathoms, which depth we carried all the way to the small Island ahead, which we reached by Noon, at which time it bore South, distant near 1/2 a Mile; depth of Water 5 fathoms. The most northermost land we had in sight (being part of the same Chain of Islands we have had to the Northward of us since we entered the Passage) bore North 71 degrees East; Latitude in, by Observation, 10 degrees 33 minutes South, Longitude 219 degrees 22 minutes West. In this situation we had no part of the Main land in sight. Being now near the island, and having but little wind, Mr. Banks and I landed upon it, and found it to be mostly a barren rock frequented by Birds, such as Boobies, a few of which we shott, and occasioned my giving it the name of Booby Island.* (* Booby Island is now the great landmark for ships making Torres Strait from the westward. There is a light upon it.) I made but very short stay at this Island before I return'd to the Ship; in the meantime the wind had got to the South-West, and although it blow'd but very faint, yet it was accompanied with a Swell from the same quarter. This, together with other concuring Circumstances, left me no room to doubt but we had got to the Westward of Carpentaria, or the Northern extremity of New Holland, and had now an open Sea to the Westward; which gave me no small satisfaction, not only because the danger and fatigues of the Voyage was drawing near to an end, but by being able to prove that New Holland and New Guinea are 2 separate Lands or Islands, which until this day hath been a doubtful point with Geographers.* (* Luis Vaez de Torres, commanding a Spanish ship in company with Quiros in 1605, separated from his companion in the New Hebrides. He afterwards passed through the Strait separating New Guinea from Australia, which now bears his name. This fact, however, was little known, as the Spaniards suppressed all account of the voyage; and though it leaked out later, the report was so vague that it was very much doubted whether he had really passed this way. On most charts and maps of the period, New Guinea was shown joined to Australia, and to Cook the establishment of the Strait may fairly be given. Only the year before Bougainville, the French navigator, who preceded Cook across the Pacific, and who was steering across the Coral Sea on a course which would have led him to Lizard Island, abandoned his search in that direction, after falling in with two reefs to the eastward of the Barrier, because he feared falling amongst other shoals, and had no faith whatever in the reports of the existence of Torres Strait. Had he persevered, he would have snatched from Cook the honour of the complete exploration of Eastern Australia, and of the verification of the passage between it and New Guinea. Bougainville paid dearly for his caution, as he found that retracing his steps against the trade wind, in order to pass eastward and northward of New Guinea, occupied such a weary time, that he and his people were nearly starved before they reached a place of refreshment.)
[Description of Endeavour Strait.]
The North-East entrance of this passage or Strait lies in the Latitude of 10 degrees 27 minutes South, and in the Longitude of 218 degrees 36 minutes West from the Meridian of Greenwich.* (* As before mentioned, this longitude is over a degree in error. The sun was not available for lunars until the 24th August, and the first was observed on the 25th, when the ship was at Booby Island; but the result is not recorded in Mr. Green's log. Mr. Green was at this time ill. The latitude is a clerical error for 10.37, which Cook's chart shows, and is nearly correct.) It is form'd by the Main, or the northern extremity of New Holland, on the South-East, and by a Congeries of Islands to North-West, which I named Prince of Wales's Islands. It is very Probable that the Islands extend quite to New Guinea;* (* This conjecture was very near the truth. The whole of Torres Strait is obstructed by either islands or reefs that leave very little passage.) they are of Various Extent both for height and Circuit, and many of them seem'd to be indifferently well Cloath'd with wood, etc., and, from the smokes we saw, some, if not all of them, must be inhabited. It is also very probable that among these Islands are as good, if not better, passages than the one we have come thro', altho' one need hardly wish for a better, was the access to it from the Eastward less dangerous; but this difficulty will remain until some better way is found out than the one we came, which no doubt may be done was it ever to become an object to be looked for.* (* It is the western and not the eastern approach of Endeavour Strait that forms the difficulty, now the locality has been charted, for vessels of deeper draught than the Endeavour; though for small craft, as Cook says, you can hardly wish for a better.) The northern Extent of the Main or outer reef, which limit or bounds the Shoals to the Eastward, seems to be the only thing wanting to Clear up this point; and this was a thing I had neither time nor inclination to go about, having been already sufficiently harrass'd with dangers without going to look for more.* (* The east coast of Australia, which Cook had now followed from end to end, is 2000 miles in extent. He took four months over it, much less time than he had given to New Zealand; but this is easily accounted for. His people were getting worn out, and he was haunted by fears of not getting off the coast before the North-West monsoon set in, which would have been a foul wind for him in getting from Torres Straits to Batavia, and his provisions were running short. Besides this, there was the grave doubt whether Australia and New Guinea were really separated. If this turned out to be false, there was a long round to make, back to the eastern extremity of the latter, and the voyage to Batavia would have been infinitely extended. Considering these circumstances, Cook's exploration of the coast was wonderful, and the charts attached to this book attest the skill and unwearied pains taken in mapping it from such a cursory glance. He only stopped at four places: Botany Bay, Bustard Bay, Thirsty Sound, and the Endeavour River; and from the neighbourhood of these, with the view obtained as he coasted along, he had to form his opinion of the country--an opinion, as we shall see, singularly correct.)
This passage, which I have named Endeavour Straits, after the Name of the Ship, is in length North-East and South-West 10 Leagues, and about 5 leagues broad, except at the North-East entrance, where it is only 2 Miles broad by reason of several small Islands which lay there, one of which, called Possession Island, is of a Moderate height and Circuit; this we left between us and the Main, passing between it and 2 Small round Islands, which lay North-West 2 Miles from it. There are also 2 Small low Islands, called Wallice's Isles,* (* These are probably called after Captain Wallis, who made a voyage across the Pacific in the Dolphin in 1767, and discovered Tahiti.) laying in the Middle of the South-West entrance, which we left to the southward; the depth of Water we found in the Straits was from 4 to 9 fathoms. Every where good Anchorage, only about 2 Leagues to the Northward of Wallice's Islands is a Bank, whereon is not more than 3 fathoms at low Water, but probable there might be found more was it sought for. I have not been particular in describing this Strait, no more than I have been in pointing out the respective Situations of the Islands, Shoals, etc., on the Coast of New Wales; for these I refer to the Chart, where they are deliniated with all the accuracy that Circumstances would admit of.
With respect to the Shoals that lay upon this Coast I must observe, for the benefit of those who may come after me, that I do not believe the one 1/2 of them are laid down in my Chart; for it would be Absurd to suppose that we Could see or find them all. And the same thing may in some Measure be said of the Islands, especially between the Latitude of 20 and 22 degrees, where we saw Islands out at Sea as far as we could distinguish any thing. However, take the Chart in general, and I believe it will be found to contain as few Errors as most Sea Charts which have not undergone a thorough correction.* (* Cook's pride in his chart is well justified, as its general accuracy is marvellous, when one considers that he simply sailed along the coast. The great feature of this shore, however--the Barrier Reef--only appears on it at its northern end, where its approach to the land caused Cook to make such unpleasant acquaintance with it. See charts.) The Latitude and Longitude of all, or most of, the principal head lands, Bays, etc., may be relied on, for we seldom fail'd of getting an Observation every day to correct our Latitude by, and the Observation for settling the Longitude were no less Numerous, and made as often as the Sun and Moon came in play; so that it was impossible for any Material error to creep into our reckoning in the intermediate times. In justice to Mr. Green,* (* From this phrase, and from various remarks in Mr. Green's own log, it would appear that Mr. Green was not very easy to get on with; but there is no doubt of his unwearied zeal in astronomical observations.) I must say that he was indefatigable in making and calculating these observations, which otherwise must have taken up a great deal of my time, which I could not at all times very well spare; not only this, but by his instructions several of the petty Officers can make and calculate these observations almost as well as himself. It is only by such Means that this method of finding the Longitude at Sea can be put into universal practice; a Method that we have generally found may be depended upon within 1/2 a degree, which is a degree of Accuracy more than sufficient for all Nautical purposes. Would Sea Officers once apply themselves to the making and calculating these Observations they would not find them so very difficult as they at first imagine, especially with the Assistance of the Nautical Almanack and Astronomical Ephemeris, by the help of which the Calculation for finding the Longitude takes up but little more time than that of an Azimuth for finding the Variation of the Compass; but unless this Ephemeris is Published for some time to come, more than either one or 2 Years, it can never be of general use in long Voyages, and in short Voyages it's not so much wanted.* (* The "Nautical Almanac" was first published for 1767. That for 1770 was not published until 1769; but it seems probable that Cook either had proof sheets, or the manuscript calculations.) Without it the Calculations are Laborious and discouraging to beginners, and such as are not well vers'd in these kind of Calculations.
