nothing," the stranger answered in a rough voice; "it was chance, or God, if you prefer it, that did everything, and I was only the instrument. My conduct would have been the same to any other person; so keep your gratitude—which I do not ask of you. Who knows," he added ironically, "whether you may not some day repent of having contracted any obligations toward me?"

The horseman felt internally pained at the way in which his advances were received by a man who scarce five minutes previously had saved his life. Not knowing to what he should attribute this sudden change of temper, he pretended not to notice anything offensive the words might contain, and said, with exquisite politeness—

"The spot is badly chosen for a lengthened conversation, Caballero. We are still, if not strangers, at least unknown to each other. I trust that ere long all coldness and misunderstanding will cease between us, and make room for perfect confidence."

The other smiled bitterly.

"Come," he said, "your sister is near here, and must be impatient to see you."

The horseman followed him without replying; but asking himself mentally who this singular man could be, who risked his life to defend him, and yet appeared anxious to treat him as an enemy.

All the sounds of the combat had reached the maiden's ear: she had heard them while kneeling on the ground, half dead with terror, and searching her troubled memory in vain for a prayer to address to Heaven.

Then the firing had ceased: a mournful silence again spread over the desert—a silence more terrifying a thousandfold than the terrible sounds of the fight, and she remained crouching in a corner and suffering from nameless agony, alone, far from all human help, not daring to retain a single hope, and fearing at each moment to see a frightful death awaiting her. The poor girl could not have said how long she remained thus crushed beneath the weight of her terror. A person must really have suffered, to know of how many centuries a minute is composed when life or death is awaited.

Suddenly she started: her strong nerves relaxed, a fugitive flush tinged her cheek, she fancied she had heard a few words uttered in a low voice not far from her. Were her enemies again pursuing her? Or was her saviour returning to her side?

She remained anxious and motionless, not daring to make a movement or utter a cry to ask for help; for a movement might reveal her presence, a cry hopelessly ruin her.

But, ere long, the bushes were parted by a powerful hand; and two horsemen appeared at the base of the rock. The maiden stretched out her hands to them with an exclamation of delight; and, too weak to support this last emotion, she fainted.

She had recognised in the men, who arrived side by side, her brother and the stranger to whom she owed her life.

When she regained her senses, she was lying on furs in front of a large fire. The two men were sitting on her right and left; while in the rock cave, three horses were eating their provender of alfalfa.

Somewhat in the shadow a few paces from her, the maiden perceived a mass, whose form it was impossible for her to distinguish at the first glance, but which a more attentive examination enabled her to recognise as a bound man lying on the ground.

The maiden was anxious to speak and thank her liberator; but the shock she had received was so rude, the emotion so powerful, that it was impossible for her to utter a word—so weak did she feel. She could only give him a glance full of all the gratitude she felt, and then fell back into a state of feverish exhaustion and morbid apathy, which almost completely deprived her of the power of thinking and feeling, and which rendered her involuntarily ignorant of all that was going on around her.

"It is well," said the stranger, as he carefully closed a gold mounted flask and concealed it in his bosom. "Now, Caballero, there is nothing more to fear for the Señorita; the draught I have administered to her, by procuring her a calm and healthy sleep, will restore her strength sufficiently for her to be able to continue her journey at sunrise, should it be necessary."

"Caballero," the stranger answered, "you are really performing the part of Providence towards me and my sister, I know not, in truth, how to express to you the lively gratitude I feel for a procedure which is the more generous as I am a perfect stranger to you."

"Do you think so?" he answered sarcastically.

"The more I examine your face, the more convinced I am that I have met you tonight for the first time."

"You would not venture to affirm it?"

"Yes, I would. Your features are too remarkable for me not to remember them if I had seen you before; but I repeat, if you fancy you know me, you are mistaken, and an accidental resemblance to some other person is the cause of your error."

There was a momentary silence, and then the stranger spoke again, with a politeness too affected for the irony it concealed not to be seen—

"Be it so, Caballero," he answered, with a bow; "perhaps I am mistaken. Be good enough, therefore, if you have no objection, to tell me who you are, and by what fortuitous concourse of circumstances I have been enabled to render you what you are kind enough to call a great service?"

"And it is an immense one, in truth, Caballero," the stranger interrupted with warmth.

"I will not discuss that subject any longer with you, Caballero; I am awaiting your pleasure."

"Señor, I will not abuse your patience for long. My name is Don Ruiz de Moguer, and I reside with my father at a hacienda in the vicinity of Arispe. For reasons too lengthy to explain to you, and which would but slightly interest you, the presence of my sister (who has been at school for some years at the Convent of the Conception at El Rosario) became indispensable at the hacienda. By my father's orders I set out for El Rosario a few months ago, in order to bring my sister back to her family. I was anxious to rejoin my father; and hence, in spite of the observations made to me by persons acquainted with the dangers attending so long a journey through a desert country, I resolved to take no escort, but start for home merely accompanied by two peons, on whose courage and fidelity I could rely."

"My sister who had been separated from her family for several years, was as eager as myself to quit the convent; and hence we soon set out. For the first few days all went well; our journey was performed under the most favourable auspices, and my sister and I laughed at the anxiety and apprehensions of our friends, for we had begun to believe ourselves safe from any dangerous encounter."

"But yesterday at sunset, just as we were preparing our camp for the night, we were suddenly attacked by a party of bandits, who seemed to emerge from the ground in front of us, so unforeseen was their apparition. Our poor brave peons were killed while defending us; and my sister's horse, struck by a bullet in the head, threw her. But the brave girl, far from surrendering to the bandits, who rushed forward to seize her, began flying across the savannah. Then I tried to lead the aggressors off the scent, and induce them to pursue me. You know the rest, Caballero; and had it not been for your providential interference, it would have been all over with us."

There was a silence, which Don Ruiz was the first to break.

"Caballero," he said, "now that you know who I am, tell me the name of my saviour?"

"What good is that?" the stranger answered, sadly. "We have come together for a moment by chance, and shall separate tomorrow never to meet again. Gratitude is a heavy burden. Not knowing who I am, you will soon have forgotten me. Believe me, Señor Don Ruiz, it is better that it should be so. Who knows if you may not regret some day knowing me?"

"It is the second time you have said that, Caballero. Your words breathe a bitterness that pains me. You must have suffered very grievously for your thoughts to be so sad and your heart so
