Columbus had been succeeded in authority in Hispaniola by Francisco de Bobadilla, and the latter in turn had in 1501 given way to Nicholas de Ovando. It does not appear that Ovando sought to colonize Cuba. But he did wish to determine its extent, and whether it was insular or continental, and in a memorial to the King of Spain he broached a proposal for at least its littoral exploration. Ferdinand gave him, however, no encouragement. On the contrary, he forbade him to spend any public money on so needless and useless an enterprise. Ovando then decided to undertake the exploit at his own charge, and, according to Las Casas, commissioned Sebastian de Ocampo to explore the coasts of the country and, if he found it to be an island, to circumnavigate it. This Ocampo did, returning to Hispaniola in the fall of 1508 with the report that he had sailed completely round Cuba. On the way, he said, he had made occasional landings, and had found the whole island to be inhabited by a kindly and intelligent people, well disposed toward Spain. Immediately following this expedition, various efforts were made to colonize Cuba, and to enter into relations with the natives. Conspicuous among these efforts was one which had for its object the introduction of Christianity into Cuba, and of which an interesting account is given by Martin Ferdinand de Enciso in his "Suma de Geografia," the first book ever published about America. Enciso, it will be remembered, was a partner of Alonzo de Ojeda, that brilliant and gallant cavalier of Spain who in 1508 was Governor of Nueva Andalusia, a region which we now know as the Caribbean coast of Colombia. It was Enciso who in 1509 went to Uraba to the relief of Francisco Pizarro, who had been in command there but who had become discouraged, had suffered heavy losses from attacks by the natives, and who was about to abandon the place. It was on one of Enciso's ships, too, that his friend Vasco Nunez de Balboa, concealed in a cask to avoid his creditors, escaped from Hispaniola and was conveyed to Darien, thus getting his opportunity to cross the isthmus and to discover the Pacific Ocean.
