Montes suddenly grasped the significance of this scene and it had strange effect upon him. Yaqui father and son--husband and wife--mother and child did not yet realize that here they were to be parted--that this separation was forever. Then one young woman, tall, with striking dark face, beautiful with the grace of some wild creature, instinctively divined the truth and she cried out hoarsely. The silence, the stoicism of these Indians seemed broken. This woman had a baby in her arms. Running across the aisle of sand, she faced a huge Yaqui and cried aloud in poignant broken speech. This giant was her husband and the father of that dusky-eyed baby. He spoke, laid a hand on her and stepped out. Perez, who had been at the other end of the aisle, saw the movement and strode toward them. “Back, Yaqui dogs!” he yelled stridently, and he flashed his bright sword. With tremendous stride the Yaqui reached Perez and towered over him. “_Capitan_, let my wife and child go where Yaqui goes,” demanded the Indian in deep voice of sonorous dignity. His Spanish was well spoken. His bearing was that of a chief. He asked what seemed his right, even of a ruthless enemy. But Perez saw nothing but affront to his authority. At his order the _rurales_ clubbed Yaqui back into his squad. They would have done the same for the stricken wife, had she not backed away from their threatening advances. She had time for a long agonized look into the terrible face of her husband. Then she was driven away in one squad and he was left in the other. * * * * * Montes thought he would forever carry in memory the tragic face of that Yaqui’s wife. Indians had hearts and souls the same as white people. It was a ridiculous and extraordinary and base thing to be callous to the truth. Montes had spent not a little time in the pampas among the Gauchos and for that bold race he had admiration and respect. Indeed, coming to think about it, the Gauchos resembled these Yaquis. Montes took the trouble to go among English and American acquaintances he had made in Progreso, and learned more about this oppressed tribe. The vast plateau of northwestern Mexico, a desert and mountainous region rich in minerals, was the home of the Yaquis. For more than one hundred and sixty years there had been war between the Yaquis and the Mexicans. And recently, following a bloody raid credited to the Yaquis, the government that happened to be in power determined to exterminate them. To that end it was hunting the Indians down, killing those who resisted capture, and sending the rest to the torture of the henequen fields.
