It did not take Columbus long to explore Broa Bay sufficiently to ascertain that it was not an arm of the sea, but a mere coastal indentation; whereupon he resumed his westward cruising. A little further on, probably in the neighborhood of Batabano, he found the shore inhabited, and though neither he nor his interpreters could understand the language of the natives, they contrived to hold some communication with them by means of signs. He gleaned from them in this manner the information that far to westward, among the mountains, there was a great king, ruling in magnificence over many provinces; that he wore long white robes and was considered a semi-divine personage, and that he never spoke but conveyed his decrees in signs, which nobody dared to disobey. To what extent this was really intended by the natives, and to what extent was the mere figment of the Admiral's lively imagination, it is impossible to say. It is entirely conceivable, however, that the Cubans had some knowledge of the Aztecs and Toltecs of Mexico, and the Mayas of Yucatan, and were referring to them. Certainly they could not have referred to anybody in Cuba. But Columbus, as ever fondly believing whatever he wished to be true, confidently assumed that they were telling him of the mythical Prester John, and that he was on the shores of that potentate's domain. The mountains of which the natives spoke, he supposed, were those of Pinar del Rio, which were already in sight on the northwestern horizon. Concerning the extent of Cuba, and of the coast along which he was sailing, Columbus could get little information. He was told that the coast extended westward for at least twenty days' journey, but whether it then ended, and how it ended, he could not learn. He therefore took one of the natives with him as a guide, and resumed his voyage. Almost immediately, however, he plunged into another archipelago, almost as dense and troublesome as that through which he had passed a few days before. Making his way through it with great difficulty, he reached the coast of Pinar del Rio, and effected a landing amid swamps and forests, only to find the region uninhabited, though frequent columns of smoke rising inland indicated to him the presence of a considerable population. For some time he made his way along that inhospitable coast, which trended steadily toward the southwest, a direction agreeing with his conceptions of the Asian coast as described by Marco Polo. Surely, he thought, he was on the coast of Indo-China, headed straight for the Golden Chersonesus. If he persisted, he would cross the Indian Ocean and reach the Red Sea, whence he could complete his journey to Europe overland by way of Palestine; or he could steer southward along the African coast and around that continent, and so reach home by circumnavigating the globe.
