CHAPTER XVI

With me the question was a far different one. I had, after careful inquiry and observation, come to the conclusion that the marshes of the valley of Mexico were, in the time of Cortéz, substantially in the condition in which we find them at the present day; that the filling up they had undergone in that time was counterbalanced by the relief they had gained by the canal of Huehuetoca. The chinampas constitute an important link in the chain of proofs to establish this fact. If I have succeeded in showing that these gardens of the Aztecs, instead of floating upon the water, rested upon the muddy bottom, it follows as a matter of course that the depth of the water in the laguna could not, in the day of the Aztecs, have been materially greater than it now is.
