The president looked round the assembly, rose in the midst of a profound silence, stretched out his arm towards the general, who stood cold and passionless before him, and, after darting at him a withering glance through the holes made in the crape that concealed his face, he said in a grave, stern, and impressive voice—

"Caballeros, remember the words you are about to hear, listen to them attentively, so as to understand them, and not to be in error as to our intentions. In the first place, in order to reassure you and restore your entire freedom of mind, learn that you have not fallen into the hands of Indians thirsting for your blood, or of pirates who intend to plunder you first and assassinate you afterwards. No, you need not feel the slightest alarm. When you have acted as impartial witnesses, and are able to render testimony of what you have seen, should it be required, you will be at liberty to continue your journey, without the forfeiture of a single article. The men seated on my right and left, although masked, are brave and honest hunters. The day may perhaps arrive when you will know them; but reasons, whose importance you will speedily recognize, compel them to remain unknown for the present. I was bound to say this, señores, to you, against whom we bear no animosity, before coming to a final settlement with this man."

One of the travellers belonging to the second caravan stepped forward; he was a young man, with elegant and noble features, tall and well built.

"Caballero," he answered, in a distinct and sympathizing voice, "I thank you, in the name of my companions and myself, for the reassuring words you have spoken. I know how implacable the laws of the desert are, and have ever submitted to them without a murmur; but permit me to ask you one question."

"Speak, caballero."

"Is it an act of vengeance or justice you are about to carry out?"

"Neither, señor. It would be an act of folly or weakness if the inspirations of the heart could be blamed or doubted by honourable and loyal men."

"Enough of this, señor," the general said, haughtily; "and if you are, as you assert, an honourable man, show me your face, in order that I may know with whom I have to deal."

The president shrugged his shoulders contemptuously.

"No, Don Sebastian," he said, "for in that case the game would not be even between us. But be patient, caballero, and soon you will learn, if not who I am, at any rate the motives which have made me your implacable foe."
