On the 12th, the wind veered to the west, N.W.; and in the evening to north; and, at last, left us to a calm; that continued till midnight, when we got a breeze at south; which, soon after, veering to, and fixing at, west, we steered east; and on the 14th, in the morning, found the variation to be 13° 25' east, latitude 53° 25', longitude 87° 53' west; and in the afternoon, being in the same latitude, and the longitude of 86° 2' west, it was 15° 3' east, and increased in such a manner, that on the 15th, in the latitude of 53° 30', longitude 82° 23' west, it was 17° east; and the next evening, in the latitude of 53° 25', longitude 78° 40', it was 17° 38' east. About this time, we saw a penguin and a piece of weed; and the next morning, a seal and some diving peterels. For the three last days, the wind had been at west, a steady fresh gale, attended, now and then, with showers of rain or hail.
At six in the morning of the 17th, being nearly in the same latitude as above, and in the longitude of 77° 10' west, the variation was 18° 33' east; and in the afternoon it was 21° 38, being at that time in latitude 53° 16' S., longitude 75° 9' west. In the morning, as well as in the afternoon, I took some observations to determine the longitude by the watch; and the results, reduced to noon, gave 76° 18' 30" west. At the same time, the longitude, by my reckoning, was 76° 17' west. But I have reason to think, that we were about half a degree more to the west than either the one or the other; our latitude, at the same time, was 53° 21' S.
We steered E. by N. and E. 1/2 N. all this day, under all the sail we could carry, with a fine fresh gale at N.W. by W. in expectation of seeing the land before night; but not making it till ten o'clock, we took in the studding-sails, top-gallant sails, and a reef in each top-sail, and steered E.N.E., in order to make sure of falling in with Cape Deseada.
Two hours after, we made the land, extending from N.E. by N. to E. by S. about six leagues distant. On this discovery, we wore and brought-to, with the ship's head to the south; and having sounded, found seventy-five fathoms water, the bottom stone and shells. The land now before us could be no other than the west coast of Terra del Fuego, and near the west entrance to the Straits of Magalhaens.
