The rising wind prevented an entrance into Cumberland Bay, and after cruising about for an entire day, Carteret was obliged to content himself with reaching Mas-a-Fuero. But he met the same obstacles, and the surge which broke upon the shore interfered with his operations, and it was only with the utmost difficulty that he succeeded in shipping a few casks of water. Some of the crew, who had been forced by the state of the sea to remain on land, killed guinea fowls enough to feed the entire crew. These, with the exception of some seals and plenty of fish, were the sole result of a stay, marked by a succession of squalls and storms, which constantly placed the ship in danger. Carteret, who, owing to unfavourable winds, had had several opportunities of noticing Mas-a-Fuero, corrected many of the errors in the account of Lord Anson's voyage, and furnished many details of inestimable use to navigators. On leaving Mas-a-Fuero, Carteret steered northward in the hope of meeting the south-eastern trade wind. Carried farther than he had counted upon, he determined to seek St. Ambrose, and St. Felix Island, or the island of St. Paul. Now that the Spaniards had taken possession of and fortified Juan Fernandez, those islands might be of great value to the English in the event of war. But Mr. Green's charts and the "Elements of Navigation" by Robertson did not tally as to their situation. Carteret, having most confidence in the latter work, sought for them in the north, and failed to find them. In re-reading the description given by Waser, Davis' surgeon, he thought these two islands were identical with the land met with by that filibuster, in his route to the south of the Galapagos Islands, and that Davis' Land did not exist. This caused a double error, that of identifying St. Felix Island with Davis' Land, and of denying the existence of the latter, which is in reality Easter Island. "At this parallel," says Carteret, that is in 18 degrees west from his point of departure, "we had fresh breezes, and a strong northerly current, and other reasons for conjecturing that we were near Davis' Land, which we were seeking so carefully. But a stiff breeze rising again, we steered quarter S.W. and reached 28-1/2 degrees southern latitude, from which it follows that if this land or anything answering to it exists, I must infallibly have fallen in with it, or at least have seen it. I afterwards remained in 28 degrees south latitude, and 40 degrees west of my point of departure, and as far as I can conjecture 121 degrees west London." All the navigators combined in insisting upon the existence of a southern continent. Carteret could not conceive that Davis' Land was but a small island, a spot lost in the immensity of the ocean. As he found no continent, he decided upon the non-existence of Davis' Land. It was precisely in this way that he was misled.
