There was at this time in Mexico a brother of Cacama, a stripling much younger than himself. At the instigation of Cortés, Montezuma, pretending that his nephew had forfeited the sovereignty by his late _rebellion_, declared him to be deposed, and appointed Cuicuitzca in his place. The Aztec sovereigns had always been allowed a paramount authority in questions relating to the succession. But this was a most unwarrantable exercise of it. The Tezcucans acquiesced, however, with a ready ductility, which showed their allegiance hung but lightly on them, or, what is more probable, that they were greatly in awe of the Spaniards; and the new prince was welcomed with acclamations to his capital.[443] Cortés still wanted to get into his hands the other chiefs who had entered into the confederacy with Cacama. This was no difficult matter. Montezuma’s authority was absolute, everywhere but in his own palace. By his command, the caciques were seized, each in his own city, and brought in chains to Mexico, where Cortés placed them in strict confinement with their leader.[444] He had now triumphed over all his enemies. He had set his foot on the necks of princes; and the great chief of the Aztec empire was but a convenient tool in his hands for accomplishing his purposes. His first use of this power was to ascertain the actual resources of the monarchy. He sent several parties of Spaniards, guided by the natives, to explore the regions where gold was obtained. It was gleaned mostly from the beds of rivers, several hundred miles from the capital. His next object was to learn if there existed any good natural harbor for shipping on the Atlantic coast, as the road of Vera Cruz left no protection against the tempests that at certain seasons swept over these seas. Montezuma showed him a chart on which the shores of the Mexican Gulf were laid down with tolerable accuracy.[445] Cortés, after carefully inspecting it, sent a commission, consisting of ten Spaniards, several of them pilots, and some Aztecs, who descended to Vera Cruz and made a careful survey of the coast for nearly sixty leagues south of that settlement, as far as the great river Coatzacualco, which seemed to offer the best--indeed, the only--accommodations for a safe and suitable harbor. A spot was selected as the site of a fortified post, and the general sent a detachment of a hundred and fifty men under Velasquez de Leon to plant a colony there. He also obtained a grant of an extensive tract of land in the fruitful province of Oaxaca, where he proposed to lay out a plantation for the crown. He stocked it with the different kinds of domesticated animals peculiar to the country, and with such indigenous grains and plants as would afford the best articles for export. He soon had the estate under such cultivation that he assured his master, the emperor Charles the Fifth, it was worth twenty thousand ounces of gold.[446] FOOTNOTES:
