Sailing across the Caribbean Sea, he at length sighted two small islands to the north-west of Hispaniola, which he called the Tortugas, from the quantity of turtles seen about them, though now known as the Caymans. Passing west of these, he found himself among the islands to the south of Cuba which he had called the Queen's Gardens. Here he cast anchor. His crews were almost worn out, and the only provisions left were a little biscuit, oil, and vinegar, while they were obliged to labour incessantly at the pumps. Suddenly a tempest burst upon them. Three of their anchors were lost, and the vessels, driving together, nearly knocked each other to pieces. With the greatest difficulty they were separated, and the Admiral's ship anchored with his sole remaining cable, which in the morning was found nearly worn asunder. At the end of six days, the weather moderating, he sailed eastwards for Hispaniola. Contrary winds, however, compelled him at length to stand across for Jamaica, where, on the 23rd of June, the caravels put into Puerto Bueno, now called Dry Harbour. No natives being found, the following day they sailed eastward, and entered another harbour, called Porta Santa Gloria. Here, at length, Columbus was compelled to give up his arduous struggle against the elements; his ships, reduced to mere wrecks, could no longer be kept afloat, and he ordered them to be run aground within bowshot of the shore, and fastened side by side. Here they soon filled with water to the deck. Cabins were therefore erected at the bow and stern, for the accommodation of the crews, and the vessels were placed in the best possible state of defence against any sudden attack of the natives. To prevent his men roving about the neighbourhood, he ordered that no one should go on shore without a special licence, and every other possible precaution was taken to prevent giving offence to the Indians. Scarcely had these arrangements been made, than the natives appeared in vast numbers, bringing provisions to barter. That no disputes might arise, two persons were appointed to superintend all such trading transactions. It was feared, however, that the food thus furnished would soon fall short, in which case the Spaniards would be reduced to famine. In this emergency, Diego Mendez, with his accustomed zeal, offered to set off with three men on a foraging expedition. He was everywhere treated with the utmost kindness by the natives, who supplied him and his companions with meat and drink; and he made arrangements with the cacique of a numerous tribe that his subjects should hunt and fish, and bring cassava bread every day to the harbour. They were to receive, in exchange, various articles which they most valued. This arrangement being made, Mendez dispatched a message to apprise the Admiral, and then proceeded upon his journey, during which he visited three different caciques, who all agreed to his proposals.
