"It is the last road north of Tlascala, and runs from Huejotlipan to Yxtacamaxtitlan.

We are already east of Tlascala, and about fifteen miles from Yxtacamaxtitlan.

If we get past that town without accident, we shall then have to cross the Pass of Obispo, over the great range of mountains, and come down near Naulinco.

Once past that town our dangers will be over, for there are few towns and villages in the Tierra Caliente.

Our great danger will lie in the pass.
