On frequented roads, where such places occur, it is usual for travellers, entering upon them, to shout, so that any one, who chances to be coming from the opposite side, may have warning and halt. Sometimes this warning is neglected, and two trains of mules or llamas meet upon the ledge! Then there is a terrible scene—the drivers quarrel—one party has to submit—their animals have to be unloaded and dragged back by the heels to some wider part of the path, so that each party can get past in its turn!

Near the highest part of the road, our travellers had entered upon one of these narrow ledges, and were proceeding along it with caution. The trusty mule, that carried Doña Isidora and Leona, was in front, the horse followed, and then the llamas. It is safer to ride than walk on such occasions, especially upon mules, for these animals are more sure-footed than the traveller himself. The horse that carried Leon, however, was as safe as any mule. He was one of the small Spanish-American breed, almost as sure-footed as a chamois.

The torrent rushed and thundered beneath. It was fearful to listen and look downward; the heads of all were giddy, and their hearts full of fear. Guapo, alone accustomed to such dangers, was of steady nerve. He and Don Pablo afoot were in the rear.

They had neared the highest point of the road, where a jutting rock hid all beyond from their view. They were already within a few paces of this rock, when the mule—which, as we have stated, was in the front—suddenly stopped, showing such symptoms of terror that Doña Isidora and the little Leona both shrieked!

Of course all the rest came to a halt behind the terrified and trembling mule. Don Pablo, from behind, shouted out, inquiring the cause of the alarm; but before any answer could be given the cause became apparent to all. Around the rock suddenly appeared the head and horns of a fierce bull, and the next moment his whole body had come into view, while another pair of horns and another head were seen close behind him!

It would be difficult to describe the feelings of our travellers at that moment. The bull came on with a determined and sullen look, until he stood nearly head to head with the mule. The smoke of his wide steaming nostrils was mingled with the breath of the terrified mule, and he held his head downward, and evidently with the intention of rushing forward upon the latter. Neither could have gone back, and of course the fierce bull would drive the mule into the abyss. The other bull stood close behind, ready to continue the work if the first one failed, and, perhaps, there were many others behind!

The mule was sensible of her danger, and, planting her hoofs firmly on the hard rock, she clung closely to the precipice. But this would not have served her, had not a hand interposed in her behalf. Amidst the terrified cries of the children, the voice of Guapo was heard calling to Don Pablo,—“Your pistols, master! give me your pistols!”

Something glided quickly among the legs of the animals. It was the lithe body of the Indian. In a second’s time he appeared in front of the mule. The bull was just lowering his head to charge forward—his horns were set—the foam fell from his lips—and his eyes glanced fire out of their dark orbs. Before he could make the rush, there came the loud report of a pistol—a cloud of sulphury smoke—a short struggle on the cliff—and then a dead plunge in the torrent below!

The smoke partially cleared away; then came another crack—another cloud—another short struggle—and another distant plash in the water!

The smoke cleared away a second time. The two bulls were no longer to be seen!
