In Portugal, a Brazilian mulatto was hired at a great price by Feliciano Velho, the captain of the ship, because he professed himself well acquainted with the river La Plata, though he was, in reality, extremely ignorant. At the entrance of the river the captain, Joseph Carvalho de Pereira, according to custom, committed the entire management of the ship to this man; but more ignorant than a brute, he made a dangerous error at the very threshold. He took the ship to such a distance from the east shore, which it ought to have kept in sight, that nothing but water and sky was to be seen. On perceiving which, "Holloa!" exclaimed the captain, "you will lose my ship before the sun sets!" This sudden speech proved prophetic: for leaning over the side of the vessel, at about two o'clock in the afternoon, I observed that the water in a certain place was unusually disturbed, and suspecting the truth of the matter, disclosed the circumstance to the captain, who, ascending a mast as quick as possible, perceived that we were steering directly towards the English Shoal, and immediately ordered the prow of the ship to be turned towards the east: for that repercussion of the waters arose, as I suspected, from the neighbouring quicksands. About evening we cast anchor in very shallow water, so that the ship hardly floated at all. After sun-set there came on a furious tempest. While the sky bellowed with thunder, a violent south wind raised huge billows in the river, and created much alarm lest the ship, which was fastened to a muddy bottom with a very bad anchor, should be either dashed upon the rocks of La Isla de Flores on one side, or upon the English Shoal on the other; for the former were on our left, and the latter on our right, at no great distance. Consequently, the sailors were forced to toil day and night in pulling away the anchors and strengthening the cables. This formidable storm lasted two days. On St. Stephen's day, about noon, the captain thought fit to remove from this dangerous neighbourhood. But after a few moments sail we were suddenly forced to cast anchor, for, by the sounding-line, sands were discovered to be close at hand.
