Notwithstanding the actual control exercised by the Spaniards through their royal captive, Cortés felt some uneasiness when he reflected that it was in the power of the Indians at any time to cut off his communications with the surrounding country and hold him a prisoner in the capital. He proposed, therefore, to build two vessels of sufficient size to transport his forces across the lake, and thus to render himself independent of the causeways. Montezuma was pleased with the idea of seeing those wonderful “water-houses,” of which he had heard so much, and readily gave permission to have the timber in the royal forests felled for the purpose. The work was placed under the direction of Martin Lopez, an experienced ship-builder. Orders were also given to Sandoval to send up from the coast a supply of cordage, sails, iron, and other necessary materials, which had been judiciously saved on the destruction of the fleet.[424] The Aztec emperor, meanwhile, was passing his days in the Spanish quarters in no very different manner from what he had been accustomed to in his own palace. His keepers were too well aware of the value of their prize, not to do everything which could make his captivity comfortable and disguise it from himself. But the chain will gall, though wreathed with roses. After Montezuma’s breakfast, which was a light meal of fruits or vegetables, Cortés or some of his officers usually waited on him, to learn if he had any commands for them. He then devoted some time to business. He gave audience to those of his subjects who had petitions to prefer or suits to settle. The statement of the party was drawn up on the hieroglyphic scrolls, which were submitted to a number of counsellors or judges, who assisted him with their advice on these occasions. Envoys from foreign states or his own remote provinces and cities were also admitted, and the Spaniards were careful that the same precise and punctilious etiquette should be maintained towards the royal puppet as when in the plenitude of his authority. After business was despatched, Montezuma often amused himself with seeing the Castilian troops go through their military exercises. He, too, had been a soldier, and in his prouder days had led armies in the field. It was very natural he should take an interest in the novel display of European tactics and discipline. At other times he would challenge Cortés or his officers to play at some of the national games. A favorite one was called _totoloque_, played with golden balls aimed at a target or mark of the same metal. Montezuma usually staked something of value,--precious stones or ingots of gold. He lost with good humor; indeed, it was of little consequence whether he won or lost, since he generally gave away his winnings to his attendants.[425] He had, in truth, a most munificent spirit. His enemies accused him of avarice. But, if he were avaricious, it could have been only that he might have the more to give away.
