“Can you tell me anything about Stewart, the American cowboy who was captured by rebels a few days ago?” asked Madeline. “Yes,” replied the officer. “There was a skirmish over the line between a company of Federals and a large force of guerrillas and rebels. The Federals were driven west along the line. Stewart is reported to have done reckless fighting and was captured. He got a Mexican sentence. He is known here along the border, and the news of his capture stirred up excitement. We did all we could to get his release. The guerrillas feared to execute him here, and believed he might be aided to escape. So a detachment departed with him for Mezquital.” “He was sentenced to be shot Thursday at sunset—to-night?” “Yes. It was rumored there was a personal resentment against Stewart. I regret that I can’t give you definite information. If you are friends of Stewart—relatives—I might find—” “I am his wife,” interrupted Madeline. “Will you please read these.” She handed him the telegrams. “Advise me—help me, if you can?” With a wondering glance at her the officer received the telegrams. He read several, and whistled low in amaze. His manner became quick, alert, serious. “I can’t read these written in Spanish, but I know the names signed.” Swiftly he ran through the others. “Why, these mean Stewart’s release has been authorized. They explain mysterious rumors we have heard here. Greaser treachery! For some strange reason messages from the rebel junta have failed to reach their destination. We heard reports of an exchange for Stewart, but nothing came of it. No one departed for Mezquital with authority. What an outrage! Come, I’ll go with you to General Salazar, the rebel chief in command. I know him. Perhaps we can find out something.” Nels made room for the officer. Link sent the car whirring across the line into Mexican territory. Madeline’s sensibilities were now exquisitely alive. The white road led into Agua Prieta, a town of colored walls and roofs. Goats and pigs and buzzards scattered before the roar of the machine. Native women wearing black mantles peeped through iron-barred windows. Men wearing huge sombreros, cotton shirts and trousers, bright sashes round their waists, and sandals, stood motionless, watching the car go by. The road ended in an immense plaza, in the center of which was a circular structure that in some measure resembled a corral. It was a bull-ring, where the national sport of bull-fighting was carried on. Just now it appeared to be quarters for a considerable army. Ragged, unkempt rebels were everywhere, and the whole square was littered with tents, packs, wagons, arms. There were horses, mules, burros, and oxen. The place was so crowded that Link was compelled to drive slowly up to the entrance to the bull-ring. Madeline caught a glimpse of tents inside, then her view was obstructed by a curious, pressing throng. The cavalry officer leaped from the car and pushed his way into the entrance.
