The immense value of such a commerce may be estimated from one fact. When, a generation after this time, one ship only of all the squadron of Magellan returned to Cadiz, after the first voyage round the world, she was loaded with spices from the Moluccas. These spices were sold by the Spanish government for so large a sum of money that the king was remunerated for the whole cost of the expedition, and even made a very large profit from a transaction which had cost a great deal in its outfit. Columbus was able, therefore, to offer mercantile adventurers the promise of great profit in case of success; and at this time kings were willing to take their share of such profits as might accrue. The letter of Toscanelli, the Italian geographer, which has been spoken of, was addressed to Alphonso V, the King of Portugal. To him and his successor, John the Second, Columbus explained the probability of success, and each of them, as it would seem, had confidence in it. But King John made the great mistake of intrusting Columbus’s plan to another person for experiment. He was selfish enough, and mean enough, to fit out a ship privately and intrust its command to another seaman, bidding him sail west in search of the Indies, while he pretended that he was on a voyage to the Cape de Verde Islands. He was, in fact, to follow the route indicated by Columbus. The vessel sailed. But, fortunately for the fame of Columbus, she met a terrible storm, and her officers, in terror, turned from the unknown ocean and returned to Lisbon. Columbus himself tells this story. It was in disgust with the bad faith the king showed in this transaction that he left Lisbon to offer his great project to the King and Queen of Spain. In a similar way, a generation afterward, Magellan, who was in the service of the King of Portugal, was disgusted by insults which he received at his court, and exiled himself to Spain. He offered to the Spanish king his plan for sailing round the world and it was accepted. He sailed in a Spanish fleet, and to his discoveries Spain owes the possession of the Philippine Islands. Twice, therefore, did kings of Portugal lose for themselves, their children and their kingdom, the fame and the recompense which belong to such great discoveries. The wife of Columbus had died and he was without a home. He left Lisbon with his only son, Diego, in or near the end of the year 1484. CHAPTER II. -- HIS PLANS FOR DISCOVERY.
