Anglo-American. In her brothers the admixture of races had been only as alloy to metal. Thomas Worth was but a darker copy of his father. John had the romance and sensitive honor of old Spain, mingled with the love of liberty, and the practical temper, of those Worths who had defied both Charles the First and George the Third. But Isabel had no soul-kinship with her father's people. Robert Worth had seen in the Yturbide residencia in Mexico the family portraits which they had brought with them from Castile. Isabel was the Yturbide of her day. She had all their physical traits, and from her large golden-black eyes the same passionate soul looked forth. He felt that it would be utter cruelty to send her among people who must always be strangers to her. So Isabel dreamed away her childhood at her mother's side, or with the sisters in the convent, learning from them such simple and useless matters as they considered necessary for a damosel of family and fortune. On the night of the Senora Valdez's reception, she had astonished everyone by the adorable grace of her dancing, and the captivating way in which she used her fan. Her fingers touched the guitar as if they had played it for a thousand years. She sang a Spanish Romancero of El mio Cid with all the fire and tenderness of a Castilian maid. Her father watched her with troubled eyes. He almost felt as if he had no part in her. And the thought gave him an unusual anxiety, for he knew this night that the days were fast approaching which would test to extremity the affection which bound his family together. He contrived to draw Antonia aside for a few moments. "Is she not wonderful?" he asked. "When did she learn these things? I mean the way in which she does them?" Isabel was dancing La Cachoucha, and Antonia looked at her little sister with eyes full of loving speculation. Her answer dropped slowly from her lips, as if a conviction was reluctantly expressed: "The way must be a gift from the past--her soul has been at school before she was born here. Father, are you troubled? What is it? Not Isabel, surely?" "Not Isabel, primarily. Antonia, I have been expecting something for twenty years. It is coming." "And you are sorry?" "I am anxious, that is all. Go back to the dancers. In the morning we can talk."
