On the 3rd of November they were off the island of Ascension or Martin Vaz. Standing on, they came in sight on the 6th of December of the mainland of South America. It was of no great height, and had a white appearance. The same night they dropped anchor in ten fathoms, at a short distance from Port Desire. Next morning, standing on to the southward, they saw before them a line of cliffs, which they understood marked the entrance to the channel. They, however, found that they had got into a wrong one, and the _Unity_ ran aground by the stern, but the wind blowing from off the land, she got clear again. Next morning, a boat being sent ahead to sound the channel, which was found to be twelve fathoms deep, they entered boldly, having a north-east wind to carry them along. After they had sailed about three miles, however, the wind began to veer, and they brought up in twenty fathoms, but the bottom being composed of slippery stones, and the wind blowing hard from the north-west, they dragged their anchors, and drifted down towards the cliffs, where there appeared every probability that they both would be lost. The _Unity_ lay with her side against the cliffs, though still afloat, while the _Horn_ stuck so fast that, as the tide fell, she remained high and dry. For some time a strong wind blowing from the north-west kept her upright, but as it dropped she sank over, until her bulwarks were under water. On seeing this, as it was impossible to right her, the explorers gave up all hopes of saving her; but, the weather remaining calm, the succeeding flood set her upright again, and she and the _Unity_, hauling out of their dangerous position, stood farther up the river. Here they again dropped anchor off King's Island. On landing they found it so thickly covered with the nests of penguins, each of which contained three or four eggs--that a man might have taken fifty or sixty without moving his position. They here also saw emus and deer with extremely long necks. While wandering over the hills they came upon several heaps of stones, beneath which they discovered bones, as they supposed of persons ten and eleven feet along. Plenty of good fish and fowls were obtained, but no water could be found for some days.
