the habitual practice of falsehood for the purpose of deceiving the Indians; the other acknowledges practices that render the character of both infamous, and would make their testimony of no weight in a court of justice unless corroborated. We must therefore feel our way as best we can.
With the rude implements of the Indians, houses of the driest blocks of mud, though covered with cement and painted with colored wash, could easily have been thrown down; but gunpowder or iron bars would have been necessary to overturn a wall composed either of stone or tepetate and cement.
Villages built of dried mud are often imposing in their appearance, and are yet most perishable; for the first overflow of waters, that shall cover but a few inches of the walls of the houses, will in a few hours reduce a whole village to a mass of ruins.
Again, the dry wall that has fallen becomes saturated, and dissolves itself into soft mud.
My hypothesis is, therefore, not without its difficulty, for at every inundation of the city in the times of the Aztecs we have to suppose it totally destroyed; an evil that could not be remedied until the water had entirely subsided, and new mud had been formed into blocks and dried in the sun, and a new village or city built every twenty-five years.
To sum up my theory of Aztec civilization: they had earthen gods, earthen cooking utensils, and earthen aqueducts; their temples were small buildings, upon moderately-sized Indian burial mounds, and their palaces and sacred inclosures were of dried mud, and of a single story in height.
