The fabled Aztec empire has almost passed from the traditions of the Mexican Indians. The name of only one of their chiefs, Montezuma, remains among them, and this name is affixed to almost every thing that has an ancient look and is in a dilapidated condition. In my wanderings among them, I never rejected their proffers of rude hospitality, and I have listened with pleasure to their wild traditions. I soon found that, like other Indians, they draw from a supernatural "dream-world" the fortitude that enables them to bear without a murmur their hard lot in the present. They readily embraced the superstitions of the Spaniards, and rendered to the virgin of Guadalupe the adoration they had formerly bestowed upon their own gods. Their conversion may be summed up in the words of Humboldt: "Dogma has not succeeded to dogma, but ceremony to ceremony. The natives know nothing of religion but the external forms of worship. Fond of whatever is connected with a prescribed order of ceremonies, they find in the Christian religion particular enjoyment. The festivals of the Church, the fire-works with which they are accompanied, the processions mingled with whimsical disguises, are a most fertile source of amusement to the lower Indians." THE VALLEY OF MEXICO. There has been a great deal of poetry and very little plain prose written about the valley of Mexico. At an early morning hour I stood upon the heights of Rio Frio; at another morning, as already said, at the Cross of the Marquis; again, upon the highest peak of the Tepeyaca, behind Guadalupe, I saw a tropical morning sun disengage itself from the snowy mountains. From these three favored spots I have looked upon the valley, where dry land and pools of water seemed equally to compose the magnificent panorama. Immense mirrors of every conceivable shape and form were reflecting back the rays of the sun, while the green shores in which they were set enhanced the effect. The white walls, and domes, and spires of the distant city heightened the effect of a picture that can only be fully appreciated by those who have looked downward through the pure atmosphere of such a lofty position; but when I came down to the common level, the charm was broken. Instead of lakelets and crystal springs, I found only pools of surface-water which the rains had left; and the canals were but the ditches from which, on either side, the dirt had been taken to build the causeway through the marsh, and were now covered with a coat of green. These lakes have no outlet, and as evaporation only takes up pure water, all the animal, vegetable, and mineral matter that is carried in is left to stagnate and putrefy in the ponds and ditches.
