The army held on its march through the intricate gorges of the sierra. The route was nearly the same as that pursued at the present day by the courier from the capital to Puebla, by the way of Mecameca.10 It was not that usually taken by travellers from Vera Cruz, who follow the more circuitous road round the northern base of Iztaccihuatl, as less fatiguing than the other, though inferior in picturesque scenery and romantic points of view.

Their progress was now comparatively easy, and they marched forward with a buoyant step, as they felt they were treading the soil of Montezuma.
