"_Tira! tira_!--fire, my lads, fire!" shouted our leader in Spanish and English.  Every one of us obeyed the order, with such effect that fully a dozen savages were knocked over, and many more wounded.  We lost not a moment in loading again.  The savages, firing their rifles at us, rode desperately up to the walls, as if intending to jump off their horses and climb over them.  Had they succeeded in so doing, they might have overwhelmed us with their numbers.  They were, however, received with another volley, delivered with such good effect that their courage failed them, and, wheeling about, they galloped away down the road as fast as they could tear.  Two Mexicans only were wounded, and not very seriously.  As may be supposed, no one went to sleep again that night; and as soon as day broke we were all in our saddles, that we might reach Durango before dark.  We now proceeded with something like military order, to avoid a surprise; for it was thought probable that the Indians might have formed an ambush on the road, with the intention of attacking us.  In the afternoon, as we rode along, we caught sight of a body of horsemen winding their way down a hill on the opposite side of the valley.  They might be Indians.  Each man examined the lock of his musket or rifle, and felt his side for his sword.  They approached, and we then saw that they were a troop of cavalry.  They were very ragged, and their horses were very miserable, and certainly they did not appear as if they could contend with the well-mounted Indians we had encountered.  These Comanche Indians, as the Mexicans call them, succeed in their forays by the rapidity of their movements.  They will accomplish a hundred miles in the day, driving several horses before them.  When one is tired, they mount another.  If any are killed by over-riding, their places can always be supplied from the nearest, cattle estate.  They strike terror among the widely-scattered inhabitants of the borders; but there is no doubt, if they were bravely and systematically opposed, they would be very quickly driven away, or compelled to have recourse to more peaceable occupations for their support Durango is a pretty little town, with white-washed, flat-roofed houses, standing on a plain surrounded by high rugged hills, a remarkable feature being the number and size of the American aloes which grow in the neighbourhood.  We put up at a _meson_, not remarkable for its cleanliness or the luxury of its provisions, and were not sorry to find ourselves once more in our saddles on our way back to Mazatlan.  We reached that place without any adventure; and the same evening, having wished our kind friends, Captain Driscoll and Mr Dwyer, good-bye, sailed for San Francisco, the wonderful port of the gold regions of California.
