Tuesday, 28th February 1769

The former part little wind and fine clear weather; the Air full as warm as in the same Degree of North Latitude at the Correspondent Season of the Year. The South-West swells still keep up, notwithstanding the Gale hath been over about 30 Hours, a proof that there is no land near in that Quarter.* The remainder part of this day fresh breezes and clear. At 9 a.m. took 3 Sets of Observations of the sun and moon in order to find the Longitude of the Ship. Wind West to North-West; course North 13 degrees West; distance 42 miles; latitude 39 degrees 33 minutes 30 seconds South, longitude 110 degrees 38 minutes West.

* These are instances of Cook's observation and seaman like perspicacity. The prevailing belief of the
time was in a great southern continent.

Thursday

Friday, 24th February 1769

First part, Calm; Middle, light breezes; latter, fresh breezes and hazey. P.M. had several Azimuths, all of which gave the Variation less than 4 degrees East, but they were a little doubtful on account of the Rowling of the Ship. What winds we have had this day hath been from the Eastward, and are the first we have had from that Quarter since we left the Latitude 58 degrees 46 minutes. Wind calm, East-North-East and East-South-East; course North 42 degrees 45 minutes West; distance 79 miles: latitude 43 degrees 37 minutes South, longitude 107 degrees 6 minutes West.

Wednesday

Thursday, 23rd February 1769

Little wind and Calm, and some Lightning, a thing we have not seen for some time past, and therefore suppose not common in these Seas in high Latitudes. Variation 5 degrees 34 minutes East. Wind North-West, calm; course North 30 degrees East; distance 13 miles; latitude 44 degrees 35 minutes South, longitude 105 degrees 52 minutes West.

Moderate breezes and fine weather the greater part of this day, and the Sea very smooth. Found by repeated trials that the South point of the Dipping Needle Dip'd 65 degrees 52 minutes below the Horizon. Wind Westerly; course South 65 degrees West; distance 58 miles; latitude 43 degrees 46 minutes South, longitude 101 degrees 34 minutes West.

Saturday

Sunday, 19th February 1769

First part, fresh Gales and Hazey; the Middle part, hazey, with drizling rain; the latter, gentle breezes and fine Clear weather, yet the Air is still Cold.

The first part of this day had fresh Gales and Cloudy; in the night thick hazey weather with heavy squalls of wind and rain, which obliged us to close-reef our Topsails. In the morning and all the forenoon had strong gales and cloudy weather, and very heavy Seas from the South-South-West, one of which broke upon the Quarter and carried away the Driver Boom. Wind North-West, West, and South; course North 74 degrees West; distance 97 miles; latitude 48 degrees 0 minutes South, longitude 94 degrees 25 minutes West.

Remarks on Passage round Cape Horn

From the Foregoing observations it will appear that we are now advanced about 12 degrees to the westward of the Strait of Magellan, and 3 1/2 degrees to the Northward of it, having been 33* (* N.B. 23 days only from Success Bay.) days in Doubling Cape Horn or the Land of Terra del Fuego, and Arriving into the Degree of Latitude and Longitude we are now in, and without being brought once under our close Reef'd Topsails since we left Strait Le Maire, a Circumstance that perhaps never hapned before to any ship in those Seas so much dreaded for Hard gales of Wind; in so much that the doubling of Cape Horn is thought by some to be a mighty thing, and others to this day prefer the Straits of Magellan. As I have never been in those Straits I can only form my Judgement on a Carefull Comparison of the Different Ships' Journals that have passed them, and those that have sail'd round Cape Horn, particularly the Dolphin's two last Voyages and this of ours, being made at the same season of the Year, when one may reasonable expect the same Winds to prevail. The Dolphin in her last Voyage was three Months in getting through the Straits, not reckoning the time she lay in Port Famine; and I am firmly perswaided
from the Winds we have had, that had we come by that Passage we should not have been in these Seas, besides the fatiguing of our People, the damage we must have done to our Anchors, Cables, Sails, and Rigging, none of which have suffer'd in our passage round Cape Horn. From what I have said it will appear that I am no advocate for the Straits of Magellan, but it should be expected that I should say something of Strait le Mair, through which we passed, and this is the more incumbant on me as it was by choice and contrary to the Advice given by Mr. Walter, the ingenious Author of Lord Anson's Voyage, who advised all Ships not to go through this Strait but to go to the Eastward of Staten Land, and likewise to stand to the Southward as far as 61 or 62 degrees south before any Endeavour is made to get to the Westward. With respect to the Passing of Strait le Mair or going round Staten Land, I look upon of little Consequence, and either one or the other to be pursued according to Circumstances; for if you happen to fall in with the land to the Westward of the Strait, and the winds favourable for going through, it certainly must be a piece of folly to lose time in going round Staten Land, for by paying a little Attention to the Directions I have already given no ill Consequences can attend; but on the Contrary if you should fall in with the land to the eastward of the Straits or the wind should prove Boisterous, or unfavourable, in any of these Cases the going to the eastward of Staten Land is the most Advisable. And next, as to running into the Latitude of 61 or 62 degrees South before any Endeavour is made to get to the Westward, is what I think no man will ever do that can avoid it, for it cannot be supposed that anyone will steer south mearly to get into a high Latitude, when at the same time he can steer west, for it is not Southing but Westing that is wanting. But this way you cannot Steer because the Wind blows almost Constantly from that Quarter, so that you have no other Choice but to stand to the Southward, close upon a Wind, and by keeping upon that Tack you not only make Southing but Westing also, and sometimes not a little when the wind Varies to the Northward of West; and the farther you advance to the Southward the better Chance you have of having the Winds from that Quarter or Easterly, and likewise of meeting with finer weather, both of which we ourselves Experienced. Prudence will direct every man when in those high Latitudes to make sure of sufficient Westing to  double all the lands before he thinks of standing to the Northward. When the winds was Westerly the Mountains on Terra Del Fuego were generally covered with dense Clouds, formed, as one may reasonably suppose, by Westerly Exhalations and by Vapours brought thither by the Westerly winds. From that Quarter come frequent Showers of rain, hail, and Snow; and after we had left the land and were standing to the Southward, with the winds westerly, dark dence clouds were Continually forming in the Horizon, and rose to about 45 degrees, where they began to dissipate. These were generally attended with Showers of Rain, or hail, and Squals of Wind, but as we advanced to the Southward, these Clouds became less dence, and in the Latitude of 60 degrees 10 minutes, when we got the winds Easterly, the weather was more serene and Milder; again as we advanced to the Northward we had a constant Clouded sky and dark gloomy weather, the whole time exceeding Cold.

Sunday

Monday, 13th February 1769

The first part of these 24 Hours, moderate breezes and Cloudy; remainder, fresh Gales and cloudy. P.M saw a great many Albetrosses and other Birds about the Ship; some were all white and about the size of Teal. Took several Observations of the sun and moon, the result of which gave 90 degrees 13 minutes West Longitude from Greenwich. The Variation of the Compass by the Mean of several Azimuths 17 degrees East. The Longitude by account is less than that by Observation, 37 minutes, which is about 20 Miles in these high Latitudes, and nearly equal to the Error of the Log line before mentioned. This near Agreement of the 2 Longitudes proves to a Demonstration that we have had no Western Current since we left the Land. Wind West, Northerly; course North 75 degrees West; distance 35 miles; latitude 49 degrees 35 minutes, longitude 90 degrees 37 minutes.

Saturday

Sunday, 12th February 1769

First and Middle parts, fresh gales and cloudy; latter, little wind and clear. Having for some time past generally found the Ship by Observation to the Northward of the Log, which is not owing to a Current as I at first imagined, but to a wrong Division of the Log line, being 2 1/2 feet in each Knot--but this is now rectified. Wind South-West by South; course North 48 degrees West; distance 113 miles; latitude 49 degrees 41 minutes South, longitude 89 degrees 36 minutes West.

P.M. had a Boat out and Shott several sorts of Birds, one of which was an Albetross as large as a Goose, whose wings when Extended measured 10 feet 2 inches; this was grey, but there are of them all White except the very tip end of their Wings. Another sort, in size between an Albetross and a large Gull, of a grey Colour, with a white Spot above their Tail about the Breadth of one's hand, and several other sorts.
