It is clear that the old idea, of the destruction of the world at the close of a cycle, has been transferred to the new mode of reckoning time.
[Illustration: VIEW AT CHICAHUASTLA] From Tlaxiaco to Teposcolula, there was a cart-road, though it was possible that no _carreta_ ever passed over it.

It presented little good scenery.

We passed the pueblos of San Martin Jilmeca, San Felipe, and San Miguel.

Just before reaching the first of these towns, the road passes over a coarse rock mass, which weathers into spheroidal shells.
At Jilmeca and some other points along the day's route the rock over which we passed was a white tufaceous material loaded with streaks of black flint.

Sometimes this black flint passes into chert and chalcedony of blue and purple tints.
