As chance would have it, Medina and I did not again meet for four or five days. In the meantime the Lieutenant and I were astonished to receive the report that an American officer had arrived in Vera Cruz some weeks since, and had been permitted to start for the City of Mexico. What could be his mission and why the Viceroy should allow him to travel through the midst of his territories was a puzzle we tried in vain to solve.

The same day I called upon Father Rocus, as I had promised, but saw him only for a few minutes and in the presence of two other priests. This, as I took it, was intended on his part as a precaution against suspicion of his friendliness. That he had no news for me was evident from his not passing me a note, though three or four opportunities offered for him to do so without detection.

A few days later I had a still greater surprise than the mystery of the envoy to Mexico. It came in the form of an invitation for the Lieutenant and myself to dine at Don Pedro's. Hope, ever unquenchable in the heart of a lover, told me that the don had repented of his harsh patriotism and was thinking to save his niece from a fate worse than death. Never was a lover more bitterly disappointed! Don Pedro and DoÑa Marguerite received us with the most suave and cordial hospitality—but Alisanda did not appear.

In answer to the Lieutenant's inquiries, DoÑa Marguerite explained, with affected regret, that SeÑorita Alisanda was indisposed, and so could not join us. I needed no more to assure me that the dear girl was under restraint. What I could not understand was why I should have been invited to dine.

The nearest I could come to an explanation was a repeated assurance from Don Pedro that he and his friends were doing their utmost to persuade Salcedo that it would be advisable to hurry me out of the country with my fellow members of the expedition. This I took as an intimation that our host still regarded me as a friend, but that the sooner I was sent away from Chihuahua the more pleased he would be. When we left, shortly before the beginning of the siesta, I had not been favored with so much as a glimpse of my lady, nor even of Chita.

That evening we went to bid farewell to Colonel Mayron, who had been ordered to a command in SoÑora. DoÑa Dolores had no word for me other than her assurance that I might rely upon the constancy of Alisanda. Of that I was already certain, yet it pleased me to receive the confirmation of the fact from her true friend.

On the other hand, I experienced a kind of savage joy when Malgares took occasion to draw me aside and warn me that Medina was looking for the first opportunity to force a duel. I made no other reply than to request that every effort be made to keep Pike in ignorance of my private troubles, and to ask Malgares to act as my second.

Being at such a disadvantage with the Government, I thought it as well to refrain from explaining that Medina would not need to force me very hard to reach an issue. Also I feared that a display of eagerness on my part might cause even so noted a duellist as the aide to hesitate, and I had become desperately desirous to break the blockade of events.

Medina did not keep me waiting long. The following afternoon he found his opportunity in a message to us from Salcedo. As an officer, he was careful to attend first to his official business, which proved to be of a character well suited to his temper. I happened to be in one of the rear rooms when Walker ushered him in to where Pike was thumbing over his beloved Pope's "Essay on Man."

Recognizing Medina's carefully modulated voice, I lingered to adjust my cravat with an extra touch. When I entered, the Lieutenant was in the midst of a reply to some remark by the aide: "—Therefore, Mr. Robinson and I have considered ourselves at liberty to discuss what we pleased, and as we pleased."

Medina met my half bow with a scowl.

"May I inquire the purpose of our distinguished guest's presence with us?" I asked.

"He brings word from the Governor-General that it is high time we put on muzzles," replied Pike, with one of his rare flashes of anger.

"Por Dios!" I mocked. "Can it be Don Nimesio Salcedo does not admire our teeth?"

"Were I His Excellency," growled Medina, "certain teeth would be gnawing crusts in the calabozo."

"But as it is, Lieutenant de Gonzales y Medina comes as an aide in the service of His Excellency," suggested Walker.

The hint was sufficient to smooth Medina's ruffled front. He fixed his gaze upon Pike, and addressed him with the most formal politeness: "Then you admit, seÑor, that yourself and SeÑor Robinson have persistently and deliberately inculcated and disseminated republican principles throughout the period of your presence in New Spain?"

"It is true," replied Pike. "We came to Chihuahua at the insistence of His Excellency, yet have been assured that we are not to regard ourselves as prisoners. Why, then, should we not discuss topics of world-wide interest with the same freedom we should enjoy in our own country?"

"Lieutenant Pike overlooks the delicacy of his situation."

"My compliments to His Excellency," retorted Pike. "My country is yet young and poor. It may as yet lack strength to resent the outrages of Britain and France. But present to His Excellency the assurance of my confidence that the Republic can exact reprisals for injuries to its citizens and officers inflicted by a secondary power."

"Satanas!" swore the aide. "You dare name the great Kingdom of Spain as not among the first of the powers?"

"The sun of Spain is fast setting. Your statesmen sneer at the mistakes and seeming weakness of the United States. I predict that unless Spain elects for freedom, within a century she will be shorn of the last of her glory, while free America shall grow in might beyond the grandest dreams of her citizens!"

"It is with the present we have now to deal, seÑor," sneered Medina. "His Excellency sends you fair warning. Those who have permitted you to indulge in your Jacobinical and atheistic discourse in their company, and in particular those who have themselves indulged in the treasonous discussions, are all noted, and their cases will be attended to in due time."

"That, seÑor, is doubtless one of the prerogatives arrogated to itself by tyranny," said Pike. "As for SeÑor Robinson and myself, we are citizens of the United States, and not subjects of His Most Catholic Majesty. We propose to continue to express our opinions freely on all subjects."

"I shall report your reply to His Excellency," said Medina, rising. "Rest assured your conduct will be represented in no very favorable view to your Government."

"As an officer of the army of the Republic, I am responsible to my Government, and to none other," replied Pike, now fairly boiling with rage. Fearful of his dignity, he gave Medina a curt bow, and withdrew to our bedchamber.

"Nom de Dieu!" gasped Walker, astonished that any one could have so dared the power of the Governor-General.

Medina looked aside at me, and saw me smiling.

"SeÑor Robinson is pleased to be amused," he said with a feline suavity which told me the time had come.

"It is most amusing, seÑor," I replied. "That any one could be foolish enough to imagine the possibility of intimidating Lieutenant Zebulon Montgomery Pike is little short of ridiculous."

"Por Dios! Say rather it is an absurdity to expect courteous compliance from the bearer of so barbarous a name."

"How of my name?" I asked, with mock concern. "Is it also displeasing to you?"

He stepped close to me, with a menacing look. "Your name, SeÑor Spy, is one to be linked in infamy with that of your double-dyed traitor, General Wilkinson, who for twenty years and more has been in the regular pay of His Most Catholic Majesty."

My palm struck full across his mouth with a force that sent him reeling. For a moment he stood in speechless fury, plucking at his sword-hilt. I grasped the back of the chair in which I had been sitting, for my pistols were in the bedchamber, and I had no mind to be run through. But Walker stepped between us, and muttered a hasty word to Medina. The latter made a sign for him to follow, and strode out into the court. Walker was out and back in two minutes.

"Sacre!" he protested, in great concern. "What am I to do? He insists that I shall serve as his second. Yet with you as my guest—"

"Accept, by all means. It would give me great pleasure. My one desire is to keep this from my friend. The fewer who know of it the better."

"But a second for yourself?" he questioned. "Entre nous, I should far prefer to serve you than your opponent."

"My thanks. But doubtless Lieutenant Don Faciendo will second me. I will call upon him at once, and you can follow with such communications as Lieutenant Medina desires to transmit."

"At your bidding, doctor. Nom de Dieu! what a blow you gave him! and with the open hand! My lips are now sealed—yet it is a fact that you have choice of weapons. You will of course advise with Lieutenant Malgares."

I waved him off, and as he went out again to tell Medina he would serve, I hastened in to Pike. He was pacing up and down the bedchamber like a caged panther.

"Has he gone?" he demanded. I nodded. "It's well—it's well! I could not answer for the consequences should I have to face his sneer again before I've had time to cool. By the Almighty, had he spoken in his own name and not as a messenger, I'd have challenged him, John!"

"Doubtless. But this menace by the Governor-General?"

"It cannot be he will go to extremes."

"Yet would it not be as well to consult with our friends? They may have knowledge of Salcedo's temper."

"We can rely upon Zuloaga and, I believe, your Don Pedro."

"Go to them, then, and I will look for Malgares."

"Very well. I will call upon SeÑor Vallois, and will meet you later at Zuloaga's, if Malgares can come."

With this, we threw on hat and coat and started off in the gathering twilight, on diverging paths. A few minutes of sharp walking brought me to the Mayron mansion, where I was so fortunate as to find Malgares at home and alone. Having first told of Salcedo's implied threat, I stated my own personal affair briefly, and recalled his promise to act as my second.

"Poder de Dios!" he exclaimed. "Nothing would give me greater pleasure. You will choose pistols?"

"Can he shoot?"

"Not at all."

"Then let it be swords," I decided.

"Santisima Virgen! you are no swordsman. He will spit you with the first thrust of his rapier."

"I said swords, Don Faciendo. My thought was the straight cutlass of your Texas cavalry. I have hefted a sabre, and your cutlasses must swing much the same."

"It is true, amigo, that the regulation cutlass would put you to a slightly less disadvantage compared to the rapier. There would be more play for your strength. Yet Medina is an expert—a master swordsman. You would have no chance. He means to kill you."

"I have quickness and strength. The odds are not so great as you fear. But with pistols, he would be absolutely at my mercy."

"Then you insist?"

A lackey announced Walker.

"I insist," I replied, as Walker bowed himself in.

"What time?" asked Malgares.

"The sooner the better."

At this he excused himself, and conducted Walker into another room. I spent the brief interval of waiting admiring a glorious painting by Velasquez for which Malgares had paid a fabulous sum in gold ingots. My enjoyment was not forced or feigned. With the assurance of action in the immediate future, I really felt lighter and easier in mind than at any time since the ball.

Malgares returned, with a clouded brow. "He was astonished. I do not wonder. Men nowadays are not usually so chivalrous as to give the game into the hands of their opponents."

"It is a case of two sets of loaded dice," I replied. "Mine are loaded beyond all question of fair play."

"And his the same!"

"That is to be seen. You accepted the challenge? All is arranged?"

Malgares nodded, still troubled. "I could do none else. We meet them at sunrise to-morrow, at the east end of the aqueduct. It is possible we may have use for your pistols. Have them ready. I shall call for you in good time, with my coach."

"You think there may be need of it to bring me home," I rallied him.

"God forbid!" he protested, crossing himself. "My only thought was that you might pass unobserved."

"True," I replied, and I hastened to explain my reasons for not wishing Pike to become involved in the affair.

I was barely in time, for I had no more than finished when the Lieutenant was announced. Not finding Don Pedro at home, he had called upon two or three other friends, who had expressed great concern for our safety, and advised him to consult with Malgares. Don Faciendo looked grave, but expressed a belief that all would be well if we held on as before with a bold front. This was also the opinion of the friends with whom we spent the evening at SeÑor Zuloaga's.
