For an instant Paul was superstitiously struck with the fatal infelicity of Yerba's selection of a foreign name, that now seemed only to invite that comment and criticism which she should have avoided. Nor could he explain it at length to the General without assisting and accenting the deception, which he was always hoping in some vague way to bring to an end. He was sorry he had corrected the General; he was furious that he had allowed himself to be confused.

Happily his companion had misinterpreted his annoyance, and with impulsive German friendship threw himself into what he believed to be Paul's feelings. "Donnerwetter! Your beautiful countrywoman is made the subject of curiosity just because that stupid baron is persistent in his serious attentions. That is quite enough, my good friend, to make Klatschen here among those animals who do not understand the freedom of an American girl, or that an heiress may have something else to do with her money than to expend it on the Baron's mortgages. But"—he stopped, and his simple, honest face assumed an air of profound and sagacious cunning—"I am glad to talk about it with you, who of course are perfectly familiar with the affair. I shall now be able to know what to say. My word, my friend, has some weight here, and I shall use it. And now you shall tell me WHO is our lovely friend, and WHO were her parents and her kindred in her own home. Her associates here, you possibly know, are an impossible colonel and his never-before-approached valet, with some South American Indian planters, and, I believe, a pork-butcher's daughter. But of THEM—it makes nothing. Tell me of HER people."

With his kindly serious face within a few inches of Paul's, and sympathizing curiosity beaming from his pince-nez, he obliged the wretched and conscience-stricken Hathaway to respond with a detailed account of Yerba's parentage as projected by herself and indorsed by Colonel Pendleton. He dwelt somewhat particularly on the romantic character of the Trust, hoping to draw the General's attention away from the question of relationship, but he was chagrined to find that the honest warrior evidently confounded the Trust with some eleemosynary institution and sympathetically glossed it over. "Of course," he said, "the Mexican Minister at Berlin would know all about the Arguello family: so there would be no question there."

Paul was not sorry when the time came to take leave of his friend; but once again in the clear moonlight and fresh, balmy air of the Allee, he forgot the unpleasantness of the interview. He found himself thinking only of his ride with Yerba. Well! he had told her that he loved her. She knew it now, and although she had forbidden him to speak further, she had not wholly rejected it. It must be her morbid consciousness of the mystery of her birth that withheld a return of her affections,—some half-knowledge, perhaps, that she would not divulge, yet that kept her unduly sensitive of accepting his love. He was satisfied there was no entanglement; her heart was virgin. He even dared to hope that she had ALWAYS cared for him. It was for HIM to remove all obstacles—to prevail upon her to leave this place and return to America with him as her husband, the guardian of her good name, and the custodian of her secret. At times the strains of a dreamy German waltz, played in the distance, brought back to him the brief moment that his arm had encircled her waist by the crumbling wall, and his pulses grew languid, only to leap firmer the next moment with more desperate resolve. He would win her, come what may! He could never have been in earnest before: he loathed and hated himself for his previous passive acquiescence to her fate. He had been a weak tool of the colonel's from the first: he was even now handicapped by a preposterous promise he had given him! Yes, she was right to hesitate—to question his ability to make her happy! He had found her here, surrounded by stupidity and cupidity—to give it no other name—so patent that she was the common gossip, and had offered nothing but a boyish declaration! As he strode into the hotel that night it was well that he did not meet the unfortunate colonel on the staircase!

It was very late, although there was still visible a light in Yerba's salon, shining on her balcony, which extended before and included his own window. From time to time he could hear the murmur of voices. It was too late to avail himself of the invitation to join them, even if his frame of mind had permitted it. He was too nervous and excited to go to bed, and, without lighting his candle, he opened the French window that gave upon the balcony, drew a chair in the recess behind the curtain, and gazed upon the night. It was very quiet; the moon was high, the square was sleeping in a trance of checkered shadows, like a gigantic chessboard, with black foreshortened trees for pawns. The click of a cavalry sabre, the sound of a footfall on the pavement of the distant Konigsstrasse, were distinctly audible; a far-off railway whistle was startling in its abruptness. In the midst of this calm the opening of the door of the salon, with the sudden uplifting of voices in the hall, told Paul that Yerba's guests were leaving. He heard Dona Anna's arch accents—arch even to Colonel Pendleton's monotonous baritone!—Milly's high, rapid utterances, the suave falsetto of Don Caesar, and HER voice, he thought a trifle wearied,—the sound of retiring footsteps, and all was still again.

So still that the rhythmic beat of the distant waltz returned to him, with a distinctiveness that he could idly follow. He thought of Rosario and the rose-breath of the open windows with a strange longing, and remembered the half-stifled sweetness of her happy voice rising with it from the veranda. Why had he ever let it pass from him then and waft its fragrance elsewhere? Why— What was that?

The slight turning of a latch! The creaking of the French window of the salon, and somebody had slipped softly half out on the balcony. His heart stopped beating. From his position in the recess of his own window, with his back to the partition of the salon, he could see nothing. Yet he did not dare to move. For with the quickened senses of a lover he felt the diffused and perfumed aura of HER presence, of HER garments, of HER flesh, flow in upon him through the open window, and possess his whole breathless being! It was SHE! Like him, perhaps, longing to enjoy the perfect night—like him, perhaps, thinking of—

"So you ar-range to get rid of me—ha! lik thees? To tur-rn me off from your heels like a dog who have follow you—but without a word—without a—a—thanks—without a 'ope! Ah!—we have ser-rved you—me and my sister; we are the or-range dry—now we can go! Like the old shoe, we are to be flung away! Good! But I am here again—you see. I shall speak, and you shall hear-r."

Don Caesar's voice—alone with her! Paul gripped his chair and sat upright.

"Stop! Stay where you are! How dared you return here?" It was Yerba's voice, on the balcony, low and distinct.

"Shut the window! I shall speak with you what you will not the world to hear."

"I prefer to keep where I am, since you have crept into this room like a thief!"

"A thief! Good!" He broke out in Spanish, and, as if no longer fearful of being overheard, had evidently drawn nearer to the window. "A thief. Ha! muy bueno—but it is not I, you understand—I, Caesar Briones, who am the thief! No! It is that swaggering espadachin—that fanfarron of a Colonel Pendleton—that pattern of an official, Mr. Hathaway—that most beautiful heiress of the Californias, Miss ARGUELLO—that are thieves! Yes—of a NAME—Miss Arguello—of a NAME! The name of Arguello!"

Paul rose to his feet.

"Ah, so! You start—you turn pale—you flash your eyes, senora, but you think you have deceived me all these years. You think I did not see your game at Rosario—yes, even when that foolish Castro muchacha first put that idea in your head. Who furnished you the facts you wanted? I—Mother of God! SUCH FACTS!—I, who knew the Arguello pedigree—I, who know it was as impossible for you to be a daughter of them as—what? let me think—as—as it is impossible for you to be the wife of that baron whom you would deceive with the rest! Ah, yes; it was a high flight for you, Mees—Mees—Dona Fulana—a noble game for you to bring down!"

Why did she not speak? What was she doing? If she had but uttered a single word of protest, of angry dismissal, Paul would have flown to her side. It could not be the paralysis of personal fear: the balcony was wide; she could easily pass to the end; she could even see his open window.

"Why did I do this? Because I loved you, senora—and you knew it! Ah! you can turn your face away now; you can pretend to misunderstand me, as you did a moment ago; you can part from me now like a mere acquaintance—but it was not always so! No, it was YOU who brought me here; your eyes that smiled into mine—and drove home the colonel's request that I and my sister should accompany you. God! I was weak then! You smile, senora; you think you have succeeded—you and your pompous colonel and your clever governor! You think you have compromised me, and perjured ME, because of this. You are wrong! You think I dare not speak to this puppet of a baron, and that I have no proofs. You are wrong!"

"And even if you can produce them, what care I?" said Yerba unexpectedly, yet in a voice so free from excitement and passion that the weariness which Paul had at first noticed seemed to be the only dominant tone. "Suppose you prove that I am not an Arguello. Good! you have yet to show that a connection with any of your race would be anything but a disgrace."

"Ah! you defy me, little one! Caramba! Listen, then! You do not know all! When you thought I was only helping you to fabricate your claim to the Arguellos' name, I was finding out WHO YOU REALLY WERE! Ah! It was not so difficult as you fondly hope, senora. We were not all brutes and fools in the early days, though we stood aside to let your people run their vulgar course. It was your hired bully—your respected guardian—this dog of an espadachin, who let out a hint of the secret—with a prick of his blade—and a scandal. One of my peon women was a servant at the convent when you were a child, and recognized the woman who put you there and came to see you as a friend. She overheard the Mother Superior say it was your mother, and saw a necklace that was left for you to wear. Ah! you begin to believe! When I had put this and that together I found that Pepita could not identify you with the child that she had seen. But you, senora, you YOURSELF supplied the missing proof! Yes! you supplied it with the NECKLACE that you wore that evening at Rosario, when you wished to do honor to this young Hathaway—the guardian who had always thrown you off! Ah!—you now suspect why, perhaps! It was your mother's necklace that you wore, and you said so! That night I sent the good Pepita to identify it; to watch through the window from the garden when you were wearing it; to make it sure as the Creed. I sent her to your room late that night when you had changed your dress, that she might examine it among your jewels. And she did and will swear—look you!—SWEAR that it is the one given you as a child by the woman at the convent, who was your mother! And who was that woman—eh? Who was the mother of the Arguello de la Yerba Buena?—who this noble ancestress?"

"Excuse me—but perhaps you are not aware that you are raising your voice in a lady's drawing-room, and that although you are speaking a language no one here understands, you are disturbing the hotel."

It was Paul, quiet, pale in the moonlight, erect on the balcony before the window. As Yerba, with a start, retreated quickly into the room, Don Caesar stepped forward angrily and suspiciously towards the window. He had his hand reached forward towards the handle as if to close the swinging sash against the intruder, when in an instant he was seized by Paul, tightly locked in a desperate grip, and whirled out on the balcony. Before he could gain breath to utter a cry, Hathaway had passed his right arm around the Mexican's throat, effectively stopping his utterance, and, with a supreme effort of strength, dragged him along the wall, falling with him into the open window of his own room. As he did so, to his inexpressible relief he heard the sash closed and the bolt drawn of the salon window, and regained his feet, collected, quiet, and triumphant.

"I am sorry," he said, coolly dusting his clothes, "to have been obliged to change the scene of this discussion so roughly, but you will observe that you can speak more freely HERE, and that any altercation WE may have in this room will be less likely to attract comment."

"Assassin!" said Don Caesar chokingly, as he struggled to his feet.

"Thank you. Relieve your feelings as much as you like here; in fact, if you would speak a little louder you would oblige me. The guests are beginning to be awake," continued Paul, with a wicked smile, indicating the noise of an opening door and footsteps in the passage, "and are now able to locate without difficulty the scene of the disturbance."

Briones apparently understood his meaning and the success of his stratagem. "You think you have saved HER from disgrace," he said, with a livid smile, in a lower tone and a desperate attempt to imitate Paul's coolness. "For the present—ah—yees! perhaps in this hotel and this evening. But you have not stop my mouth for—a—to-morrow—and the whole world, Mr. Hathaway."

"Well," said Paul, looking at him critically, "I don't know about that. Of course, there's the equal chance that you may kill me—but that's a question for to-morrow, too."

The Mexican cast a quick glance at the door and window. Paul, as if carelessly, changed the key of the former from one pocket to the other, and stepped before the window.

"So this is a plot to murder me! Have a care! You are not in your own brigand California!"

"If you think so, alarm the house. They will find us quarreling, and you will only precipitate matters by receiving the insult that will make you fight—before them."

"I am r-ready, sir, when and where you will," said Briones, with a swaggering air but a shifting, furtive eye. "Open—a—the door."

"Pardon me. We will leave this room TOGETHER in an hour for the station. We will board the night express that will take us in three hours beyond the frontier, where we can each find a friend."

"But my affairs here—my sister—I must see her."

"You shall write a note to her at that table, saying that important business—a dispatch—has called you away, and we will leave it with the porter to be delivered IN THE MORNING. Or—I do not restrict you—you can say what you like, provided she don't get it until we have left."

"And you make of me a prisoner, sir?"

"No; a visitor, Don Caesar—a visitor whose conversation is so interesting that I am forced to detain him to hear more. You can pass the time pleasantly by finishing the story I was obliged to interrupt a moment ago. Do you know this mother of Miss Yerba, of whom you spoke?"

"That's m—my affair."

"That means you don't know her. If you did, you'd have had her within call. And, as she is the only person who is able to say that Miss Yerba is NOT an Arguello, you have been very remiss."

"Ah, bah! I am not one of your—a—lawyers."

"No; or you would know that, with no better evidence than you have, you might be sued for slander."

"Ah! Why does not Miss Yerba sue, then?"

"Because she probably expects that somebody will shoot you."

"As YOU for instance?"

"Perhaps."

"And if you do NOT—eh?—you have not stop my mouth, but your own. And if you DO, you help her to marry the Baron, your rival. You are not wise, friend Hathaway."

"May I remind you that you have not yet written to your sister, and you may prefer to do it carefully and deliberately?"

Don Caesar arose with a vindictive glance at Paul, and pulled a chair before the table, as the latter placed pen, ink, and paper before him. "Take your time," he added, folding his arms and walking towards the window. "Say what you like, and don't let my presence restrain you."

The Mexican began to write furiously, then spasmodically, then slowly and reluctantly. "I war-r-n you, I shall expose all," he said suddenly.

"As you please."

"And shall say that if I disappear, you are my murderer—you understand—my MURDERER!"

"Don't consult me on a question of epithets, but go on."

Don Caesar recommenced his writing with a malign smile. There was a sudden sharp rap at the door.

Don Caesar leaped to his feet, grasped his papers, and rushed to the door; but Paul was before him. "Who is there?" he demanded.

"Pendleton."

At the sound of the colonel's voice Don Caesar fell back. Paul opened the door, admitted the tall figure of the colonel, and was about to turn the key again. But Pendleton lifted his hand in grim deprecation.

"That will do, Mr. Hathaway. I know all. But I wish to speak with Briones elsewhere, alone."

"Excuse me, Colonel Pendleton," said Paul firmly, "but I have the prior claim. Words have passed between this gentleman and myself which we are now on our way to the station and the frontier to settle. If you are willing to accompany us, I shall give you every opportunity to converse with him alone, and arrange whatever business you may have with him, provided it does not interfere with mine."

"My business," said Pendleton, "is of a personal nature, that will not interfere with any claim of yours that Mr. Briones may choose to admit, but is of a private quality that must be transacted between us now." His face was pale, and his voice, although steady and self-controlled, had that same strange suggestion of sudden age in it which Paul had before noticed. Whether Don Caesar detected it, or whether he had some other instinctive appreciation of greater security, Paul could not tell. He seemed to recover his swagger again, as he said,—

"I shall hear what Colonel Pendleton has to say first. But I shall hold myself in readiness to meet you afterwards—you shall not fear, sir!"

Paul remained looking from the one to the other without speaking. It was Don Caesar who returned his glance boldly and defiantly, Colonel Pendleton who, with thin white fingers pulling his moustache, evaded it. Then Paul unlocked the door, and said slowly, "In five minutes I leave this house for the station. I shall wait there until the train arrives. If this gentleman does not join me, I shall be better able to understand all this and take measures accordingly."

"And I tell to you, Meester Hathaway, sir," said Don Caesar, striking an attitude in the doorway, "you shall do as I please—Caramba!—and shall beg"—

"Hold your tongue, sir—or, by the Eternal!"—burst out Pendleton suddenly, bringing down his thin hand on the Mexican's shoulder. He stopped as suddenly. "Gentlemen, this is childish. Go, sir!" to Don Caesar, pointing with a gaunt white finger into the darkened hall. "I will follow you. Mr. Hathaway, as an older man, and one who has seen a good deal of foolish altercation, I regret, sir, deeply regret, to be a witness to this belligerent quality in a law-maker and a public man; and I must deprecate, sir—deprecate, your demand on that gentleman for what, in the folly of youth, you are pleased to call personal satisfaction."

As he moved with dignity out of the room, Paul remained blankly staring after him. Was it all a dream?—or was this Colonel Pendleton the duelist? Had the old man gone crazy, or was he merely acting to veil some wild purpose? His sudden arrival showed that Yerba must have sent for him and told him of Don Caesar's threats; would he be wild enough to attempt to strangle the man in some remote room or in the darkness of the passage? He stepped softly into the hall: he could still hear the double tread of the two men: they had reached the staircase—they were DESCENDING! He heard the drowsy accents of the night porter and the swinging of the door—they were in the street!

Wherever they were going, or for what purpose, HE must be at the station, as he had warned them he would be. He hastily threw a few things into his valise, and prepared to follow them. When he went downstairs he informed the porter that owing to an urgent call of business he should try to catch the through express at three o'clock, but they must retain his room and luggage until they heard from him. He remembered Don Caesar's letter. Had either of the gentlemen, his friends who had just gone out, left a letter or message? No, Excellency; the gentlemen were talking earnestly—he believed, in the South American language—and had not spoken to him.

Perhaps it was this that reminded Paul, as he crossed the square again, that he had made no preparation for any possible fatal issue to himself in this adventure. SHE would know it, however, and why he had undertaken it. He tried to think that perhaps some interest in himself had prompted her to send the colonel to him. Yet, mingled with this was an odd sense of a certain ridiculousness in his position: there was the absurdity of his prospective antagonist being even now in confidential consultation with his own friend and ally, whose functions he had usurped, and in whose interests he was about to risk his life. And as he walked away through the silent streets, the conviction more than once was forced upon him that he was going to an appointment that would not be kept.

He reached the station some ten minutes before the train was due. Two or three half-drowsy, wrapped-up passengers were already on the platform; but neither Don Caesar nor Colonel Pendleton was among them. He explored the waiting-rooms and even the half-lit buffet, but with no better success. Telling the Bahnhof Inspector that his passage was only contingent upon the arrival of one or two companions, and describing them minutely to prevent mistakes, he began gloomily to pace before the ticket-office. Five minutes passed—the number of passengers did not increase; ten minutes; a distant shriek—the hoarse inquiry of the inspector—had the Herr's companions yet gekommt? the sudden glare of a Cyclopean eye in the darkness, the ongliding of the long-jointed and gleaming spotted serpent, the train—a hurried glance around the platform, one or two guttural orders, the slamming of doors, the remounting of black uniformed figures like caryatides along the marchepieds, a puff of vapor, and the train had come and gone without them.

Yet he would give his adversary fifteen minutes more to allow for accident or delay, or the possible arrival of the colonel with an explanation, and recommenced his gloomy pacing, as the Bahnhof sank back into half-lit repose. At the end of five minutes there was another shriek. Paul turned quickly to the inspector. Ah, then, there was another train? No; it was only the up express for Basle, going the other way and stopping at the Nord Station, half a mile away. It would not stop here, but the Herr would see it pass in a few moments at full speed.

It came presently, with a prolonged despairing shriek, out of the darkness; a flash, a rush and roar at his side, a plunge into the darkness again with the same despairing cry; a flutter of something white from one of the windows, like a loosened curtain, that at last seemed to detach itself, and, after a wild attempt to follow, suddenly soared aloft, whirled over and over, dropped, and drifted slowly, slantwise, to the ground.

The inspector had seen it, ran down the line, and picked it up. Then he returned with it to Paul with a look of sympathizing concern. It was a lady's handkerchief, evidently some signal waved to the well-born Herr, who was the only passenger on the platform. So, possibly, it might be from his friends, who by some stupid mischance had gone to the wrong station, and—Gott im Himmel!—it was hideously stupid, yet possible, got on the wrong train!

The Herr, a little pale, but composed, thought it WAS possible. No; he would not telegraph to the next station—not yet—he would inquire.

He walked quickly away, reaching the hotel breathlessly, yet in a space that seemed all too brief for his disconnected thought. There were signs of animation in the hall, and an empty carriage was just reentering the courtyard. The hall-porter met him with demonstrative concern and apology. Ah! if he had only understood his Excellency better, he could have saved him all this trouble. Evidently his Excellency was going with the Arguello party, who had ordered a carriage, doubtless, for the same important journey, an hour before, yet had left only a few moments after his Excellency, and his Excellency, it would appear, had gone to the wrong station.

Paul pushed hurriedly past the man and ascended to his room. Both windows were open, and in the faint moonlight he could see that something white was pinned to his pillow. With nervous fingers he relit his candles, and found it was a note in Yerba's handwriting. As he opened it, a tiny spray of the vine that had grown on the crumbling wall fell at his feet. He picked it up, pressed it to his lips, and read, with dim eyes, as follows:—

"You know now why I spoke to you as I did to-day, and why the other half of this precious spray is the only memory I care to carry with me out of this crumbling ruin of all my hopes. You were right, Paul: my taking you there WAS AN OMEN—not to you, who can never be anything but proud, beloved, and true—but to ME of all the shame and misery. Thank you for all you have done—for all you would do, my friend, and don't think me ungrateful, only because I am unworthy of it. Try to forgive me, but don't forget me, even if you must hate me. Perhaps, if you knew all—you might still love a little the poor girl to whom you have already given the only name she can ever take from you—YERBA BUENA!"
