Soundings and navigation to the straits of Magalhaens.
On the day of our departure, we saw land till sun-set; our soundings constantly encreased, and changed from an oozy to a sandy bottom; at half past six of the clock we found thirty-five fathom, and a grey sand; and the Etoile, to whom I gave a signal for sounding on the fifteenth in the afternoon, found sixty fathom, and the same ground: at noon we had observed 36° 1′ of latitude. From the 16th to the 21st we had contrary winds, a very high sea, and we kept the most advantageous boards in tacking under our courses and close-reefed top-sails; the Etoile had struck her top-gallant masts, and we sailed without having our’s up. The 22d it blew a hard gale, accompanied with violent squalls and showers, which continued all night; the sea was very dreadful, and the Etoile made a signal of distress; we waited for her under our fore-sail and main-sail, the lee clue-garnet hauled up. This store-ship seemed to have her fore top-sail-yard carried away. The wind and sea being abated the next morning, we made sail, and the 24th I made the signal for the Etoile to come within hail, in order to know what she had suffered in the last gale. M. de la Giraudais informed me, that besides his fore top-sail yard, four of his chain plates[[58]] had likewise been carried away; he added, that all the cattle he had taken in at Montevideo, had been lost, two excepted: this misfortune we had shared with him; but this was no consolation, for we knew not when we should be able to repair this loss. During the remaining part of this month, the winds were variable, from S. W. to N. W; the currents carried us southward with much rapidity, as far as 45° of latitude, where they became insensible. We sounded for several days successively without finding ground, and it was not till the 27th at night, being in the latitude of about 47°, and, according to our reckoning, thirty-five leagues from the coast of Patagonia, that we sounded seventy fathom, oozy bottom, with a fine black and grey sand. From that day till we saw the land, we had soundings in 67, 60, 55, 50, 47, and at last forty fathom, and then we first got sight of Cape Virgins[[59]]. The bottom was sometimes oozy, but always of a fine sand, which was grey, or yellow, and sometimes mixed with small red and black gravel.

Hidden rock not taken notice of in the charts.
I would not approach too near the coast till I came in latitude of 49°, on account of a sunken rock or vigie, which I had discovered in 1765, in 48° 30′ south latitude, about six or seven leagues off shore. I discovered it in the morning, at the same moment as I did the land, and having taken a good observation at noon, the weather being very fair, I was thus enabled to determine its latitude with precision. We ran within a quarter of a league of this rock, which the first person who saw it, originally took to be a grampus.
1767. December.
The 1st and 2d of December, the winds were favourable from N. and N. N. E.; very fresh, the sea high, and the weather hazy; we made all the sail we could in day time, and passed the nights under our fore-sail, and close-reefed top-sails. During all this time we saw the birds called Quebrantahuessos or Albatrosses, and what in all the seas in the world is a bad sign, petrels, which disappear when the weather is fair, and the sea smooth. We likewise saw seals, penguins, and a great number of whales. Some of these monstrous creatures seemed to have their skin covered with such white vermiculi, which fasten upon the bottoms of old ships that are suffered to rot in the harbours. On the 30th of November, two white birds, like great pigeons, perched on our yards. I had already seen a flight of these birds cross the bay of the Malouines.
