These palaces were built chiefly of mud bricks; and time and the Spaniards have dealt so hardly with them, that even their outlines can no longer be traced.

Traces of two large teocallis are just visible, and Mr.
Bowring has some burial mounds in his grounds which will be examined some day.

There is a Mexican calendar built into the wall of one of the churches; and, as we walked about the streets of the present town, we noticed stones that must have been sculptured before the Spaniards brought in their broken-down classic style, and so stopped the development of native art.

As for the rest of old Tezcuco, it has "become heaps." Wherever they dig ditches or lay the foundations of houses, you may see the ground full of its remains.
As I said before, when speaking of the stuccoed floors near Teotihuacan, the accumulation of alluvial soil goes on very rapidly and very regularly all over the plains of Mexico and Puebla, where everything favours its deposit; and the human remains preserved in it are so numerous that its age may readily be seen.

We noticed this in many places, but in no instance so well as between Tezcuco and the hacienda of Miraflores.
