The first care of Cortez was to take precautions for his security, by planting artillery so as to command the different avenues which led to it, and posting sentinels at proper stations, with orders to observe the greatest vigilance. In the evening Montezuma returned to visit his guests, with the same pomp as in their first interview, and brought presents of great value not only to Cortez and his officers, but even to the private men. A long conference ensued, in which Cortez, in his usual style, magnified the power and dignity of his sovereign. Next morning Cortez and some of his principal attendants were admitted to a public audience of the emperor; the three following days were employed in viewing the city, the appearance of which was so far superior to any place the Spaniards had beheld in America, and yet so little resembling the structure of an European city, that it filled them with surprise and admiration. Mexico, or Tenuchtitlan, as it was anciently called, is situated on some small islands, near one side of a large lake, which is ninety miles in circumference. The access to the city was by artificial causeways or streets, formed of stones and earth, about thirty feet in breadth. These causeways were of considerable length: that on the west extended a mile and a half; that on the north-west three miles, and that towards the south six miles. On the east, the city could only be approached by canoes. Not only the temples of their Gods, but the palaces belonging to the monarch, and to persons of distinction, were of such dimensions that they might be termed magnificent. But, however the Spaniards might be amused or astonished at these objects, they felt the utmost anxiety with respect to their situation. They had been allowed to penetrate into the heart of a powerful kingdom, and were now lodged in its capital without having once met with open opposition from its monarch; but they had pushed forward into a situation where it was difficult to continue, and from which it was impossible to retire without disgrace and ruin. They could not, however, doubt of the hostility of the Mexicans, more especially as, on his march, Cortez received advice from Vera Cruz, where he had left a garrison, that a Mexican general had marched to attack the rebels whom the Spaniards had encouraged to revolt against Montezuma, and that the commander of the garrison had marched out with some of his troops to support the rebels, that an engagement had ensued, in which, though the Spaniards were victorious, the Spanish general with seven of his men, had been mortally wounded, his horse killed, and one Spaniard taken alive, and that the head of his unfortunate captive had been sent to Mexico, after being carried in triumph to different cities in order to convince the people that their invaders were not immortal.
