The men really seemed indefatigable.

One of them once took upon his head a large case of honey and carried it up the ridge on a run.

Strange as it may sound, on my first journey across the Sierra Madre I did not lose one animal by such accidents.
Climbing, climbing, climbing, one massive cordon after another, at the start through dense oak thickets, and over hills flattened and eroded with countless deep, precipitous gashes seaming the rock in every direction.

Numerous springs oozed and trickled from the stratified conglomerate along the edges, sides, and bottoms of the ravines.

The tops of some of these truncated knolls were quite swampy in the depressions, and covered with a thin-stemmed feathery grass.
