"Go," said he, "go hence, I entreat you, while I remain to appease, if possible, the wrath of the gods whom you have so dreadfully provoked." But these scenes aroused anew the religious zeal of Cortez and his companions. As they returned to their lodgings, they immediately converted one of the halls of their residence into a Christian chapel. Here the rites of the Roman Catholic Church were introduced, and the whole army of Cortez, with soldierly devotion, attended mass every day. Good Father Olmedo, with perhaps a clouded intellect, but with that recognition of the universal brotherhood of man which sincere piety ever confers, prayed fervently for God's blessing upon his frail children of every name and nation. The Spaniards estimated the population of the city at about five hundred thousand. The streets were very regularly laid out at right angles. Many of them were wide, and lined with shade-trees. The houses of the common people were small but comfortable cottages, built of reeds or of bricks baked in the sun. The dwellings of the nobles and of the more wealthy inhabitants were strongly-built mansions of stone, very extensive on the ground floor, though generally but one story high. They were inclosed in gardens blooming with flowers. Fountains of cool water, conveyed through earthen pipes, played in the court-yards. The police regulations were unsurpassed by those of any city in Europe. A thousand persons were continually employed in sweeping and watering the streets. So clean were the well-cemented pavements kept, that "a man could walk through the streets," says one of the Spanish historians, "with as little danger of soiling his feet as his hands." Day after day was passed in the interchange of visits, and in the careful examination by Cortez of the strength and the resources of the city. He had now been a week in the capital, and the question naturally arose, What is next to be done? He was, indeed, perplexed to decide this question. Montezuma treated him with such extraordinary hospitality, supplying all his wants, and leaving him at perfect liberty, that it was difficult for one, who laid any claim whatever to a conscience, to find occasion to pick a quarrel. To remain inactive, merely enjoying the luxury of a most hospitable entertainment, was not only accomplishing nothing, but was also enervating the army. It was also to be apprehended that the Mexicans would gradually regain their courage as they counted the small number of the invaders, and fall upon them with resistless power.
