They had reached Monclova, a large town in Coahuila. Here they found an acquaintance--an old comrade of the Guerrilla times. He had taken up his residence in Mexico, had married a handsome Mexican girl, and had settled down to a quiet life in a strange land. Of course he was glad to see the Boys whom he had not met since they parted in Kentucky, when he was captured and sent to prison. His home was placed at their disposal, and his Mexican wife received them with that cordial hospitality which is a characteristic of her countrywomen. Here they proposed to remain a day or two and rest. In accordance with the customs of the country, the Mexicanized American gave his old comrades a reception on the following afternoon, or rather evening after their arrival. A reception in Mexico means a ball or _fandango_. Many of the leading citizens of Monclova attended the reception, for the friend of the Jameses was esteemed a very worthy citizen and respectable gentleman. Among the guests was a young lieutenant of the Mexican army, and an American long resident in the country, who came from the vicinity of Matehuala. These two men scrutinized the faces of the Boys in a very peculiar manner, and a careful observer could have seen the flushes of anger which ever and anon overspread their countenances. Jesse had noticed their behavior, and called the attention of his brother to the strangeness of their conduct. He was sure that he had seen the American before somewhere, at some time, just when and where he could not remember. Frank was enjoying himself in the society of a fair senorita, and seemed to attach little importance to his brother's suggestions. But Jesse watched them closely, and became thoroughly convinced that he had met both men before, and he knew that the meeting had been that of enemies. The lieutenant and his companion did not remain long, but took their departure. There was at that time encamped, in the environs of Monclova, a brigade of the Mexican army, and the regiment to which the lieutenant belonged had barracks near the plaza. On leaving the ball-room, the two men went directly to the headquarters of the regiment, and found there the colonel and lieutenant-colonel. The young officer at once laid before them the knowledge which he possessed concerning the character of the men who were being entertained in Monclova that night. Both men had a score to settle with the Jameses. The account of the American dated back to 1865--that of the young officer only a little more than a year, at which time, unfortunately, in one of the border broils, frequent about that time between Mexicans and Texans, the Boys had killed a brother of the officer.
