484 THE PORTRAIT OF A LADY. smoothly as might be to the end. But it was only because she had thft end in view that she was able to go on. She had been touched with a point that made her quiver, and she needed all the alertness of her will to repress her agitation. Her only safety was in not betraying herself. She did not betray herself ; but the startled quality of her voice refused to improve she couldn't help it while she heard herself say she hardly knew what.
