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.* 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;** 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.*** 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.****
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,***** 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.****** 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,******* 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.******** Without it the Calculations are Laborious and discouraging to beginners, and such as are not well vers'd in these kind of Calculations.
* 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.
** This conjecture was very near the truth. The whole of Torres Strait is obstructed by either islands or reefs that leave very little passage.
*** 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 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.
***** These are probably called after Captain Wallis, who made a voyage across the Pacific in the Dolphin in 1767, and discovered Tahiti.
****** 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.
******* 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.
******** 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.
