Not satisfied with receiving the reports of his numerous officers, the monarch went frequently in disguise among his people, listening to their complaints, and severely punishing wrongdoers. Being filled with deep religious feeling, he openly confessed his faith in a God far greater than the idols of wood and stone worshiped by his subjects, and built a great temple which he dedicated to the Unknown God. After fifty years' reign this great monarch died, and was succeeded by his son Nezahualpilli, who resembled his father in his tastes, encouraging learning, especially astronomical studies, and building magnificent public edifices. He was severe in his morals, and stern in the execution of justice. In his youth he had been devoted to war, and had extended the dominion of Tezcuco; but he afterwards became indolent, and spent much of his time in retirement. His Mexican rival took advantage of this, for as the rule of Tezcuco became relaxed distant provinces revolted, the discipline of the army became shaken, and Montezuma, partly by force, partly by fraud, possessed himself of a considerable portion of its dominions, and assumed the title, hitherto held by the Tezcucan princes, of Emperor. These misfortunes pressed heavily on the spirits of the king, and their effect was increased by certain gloomy prognostics of a great calamity, which was shortly to overwhelm the country. His health rapidly gave way. He had died but two years before, and had been succeeded by his son Cacama, the present king, a young prince who was two-and-twenty years old when he ascended the throne, after a sanguinary war with an ambitious younger brother. In Tezcuco, as in Mexico, the office of king was elective and not hereditary. It was, indeed, confined to the royal family; but the elective council, composed of the nobles and of the kings of the other two great confederate monarchies, selected the member of that family whom they considered best qualified to rule. Roger was greatly impressed with these accounts of the government of this strange country. It appeared to him that art and learning were there held of much higher account than they were in England; and it seemed more strange to him than ever, that a people so enlightened could be guilty of such wholesale human sacrifices as those of which he had heard, and had indeed seen proof; still more that they could absolutely feast upon the flesh of these victims of their cruel superstitions. Descending into the valley the party avoided, as before, the numerous cities in the plain. The Tezcucans told him that they did so simply because they were anxious to arrive as soon as possible at the capital; but as Roger learned from them that the sway of Montezuma was paramount in this part of the valley, he thought it probable that they feared the Aztecs might take him from their hands, and send him direct to the emperor.
