But the Mexicans were evidently quite accustomed to such happenings, which seemed to be in the regular line of their travel.
I could not help admiring the agility as well as the valour of my Mexican packers and muleteers on such occasions.

They moved about as sure-footed and quick as sailors on their ship, and always on the alert.

Whenever one of the poor beasts lost its foothold, the men would instantly run after it, and as soon as some obstacle stopped its downward career they would be by its side and relieve it of its burden.

Of course, sometimes the animal was badly bruised about the head, and unable to carry a pack for a few days; but, _mira-bile dictu!_ in the majority of cases it rose to its feet.

Then, after giving it a few moments' respite, the packers would strap the cargo again on its back, unless they deemed it proper to take a part of it upon themselves, so that the beast might more safely climb the declivity.
