There was a well-organized police, and a system of relays which worked with perfect regularity, and enabled the sovereign to transmit his orders with rapidity from one end of the empire to the other. The number and beauty of the towns, the great size of the palaces, temples, and fortresses indicated an advanced civilization, which presented a singular contrast to the ferocious manners of the Aztecs. Their polytheistic religion was in the highest degree barbarous and sanguinary; the priests formed a very numerous body, and exercised great influence even over political affairs. Side by side with rites similar to those of Christians, such as baptism and confession, the religion presented a tissue of the most absurd and bloody superstitions. The offering up of human sacrifices, adopted at the beginning of the 14th century, and used at first very sparingly, had soon become so frequent, that the number of victims immolated each year, and drawn chiefly from the conquered nations, amounted to 20,000, while under certain circumstances the number was much larger. Thus in 1486, at the inauguration of the temple of Huitzilopchit, 70,000 captives perished in a single day. The Government of Mexico was monarchical; at first the imperial power had been carefully limited, but it had increased with the various conquests, and had become despotic. The sovereign was always chosen out of the same family, and his accession was marked by the offering up of numerous human sacrifices. The Emperor Montezuma belonged to the sacerdotal caste, and in consequence his power received some unwonted development. The result of his numerous wars had been the extension of his frontiers, and the subjugation of various nations; these latter welcomed the Spaniards with eagerness, thinking that their dominion must surely be less oppressive and less cruel than that of the Aztecs. It is certain that if Montezuma, with the large force which he had at his disposal, had fallen upon the Spaniards when they were occupying the hot and unhealthy shore of Vera-Cruz, they would have been unable, in spite of the superiority of their arms and discipline, to resist such a shock; they must all have perished, or been obliged to re-embark, and the fate of the New World would have been completely changed. But the decision which formed the most salient point in the character of Cortes, was completely wanting in that of Montezuma, a prince who never could at any time adopt a resolute policy.
