Columbus then sailed to Hispaniola, where he planted a colony, of which he was made governor. It was not an easy matter to govern this island, because of the jealousies and quarrels of the Spaniards. At length Columbus returned to Spain, ill and discouraged. Columbus made a third voyage in 1498, during which he sailed along the coast of Brazil, and discovered Trinidad Island. Here his ships encountered currents of fresh water which flowed with great force into the ocean. This led Columbus to think that so large a river must flow across a great continent, and strengthened his opinion that the land was a part of the great continent of Asia. [Illustration: Map Showing how Columbus Discovered America.] After sailing farther north along the Pearl Coast, which was so called because of the pearls found there, he returned to Hispaniola. Here he found the Spaniards engaged in an Indian war, and quarreling among themselves. Some officials became jealous of him, bound him with chains, and sent him back to Spain a prisoner. Ferdinand and Isabella were much displeased at this treatment of Columbus, and set him free. A fourth voyage was made by Columbus in 1502, during which he explored the coast of Honduras in search of a strait leading to the Indian Ocean. In this venture he was unsuccessful. On his return to Spain he found his friend Queen Isabella very ill, and nineteen days after his arrival she died. After Isabella's death the king treated Columbus cruelly and ungratefully. The people had become jealous of him, and his last days were spent in poverty and distress. He never knew that he had discovered a new continent, but supposed that he had found India. Seven years after his death the king repented of his ingratitude, and caused the remains of Columbus to be removed from the little monastery in Valladolid to a monastery in Seville, where a magnificent monument was erected to his memory. In 1536 his bones were removed to the Cathedral of San Domingo in Hispaniola, and later they were taken to the cathedral in Havana. When the United States took possession of Cuba, the Spanish disinterred the bones of Columbus again and carried them to Spain, placing them in the cathedral of Seville, where they now are. VASCO DA GAMA. Both the Spaniards and the Portuguese were cut off from trade with the East, because the Turks had taken possession of Constantinople. In consequence of this, the navigators of both countries were making earnest efforts to find a water route to India. [Illustration: Vasco da Gama.] Spain, as you know, had faith in Columbus, and helped him in his plan of trying to reach India by sailing westward. But the Portuguese had a different idea. They spent their time and money in trying to sail round the African coast, in the belief that India could be reached by means of a southeast passage.
