Read the excerpt from “Clara Barton’s Childhood.” Stephen Barton, or Captain Barton as he was called, was a man of marked military tastes. In the evening, after dinner, the family would gather near the fireplace, with its thick hand-cut mantel and river rock surround. With mother in her rocking chair, knitting, and her sister Sally on the sofa with a book, Clara would perch in the armchair on her father’s knee, next to the crackling fire, and listen as he regaled her with tales of his service. “…surrounded by darkness, we sat quietly waiting for our orders to advance,” he would say. Which detail from the excerpt best characterizes Stephen Barton as a loving father?
