"Wait a moment," she said hastily. "It is right that you should know how much I also cared until--" she broke off, hesitating, and then went on, slowly and thoughtfully, with a puzzled air, as though she herself did not quite understand. "When you came back to me, in that little summer-house, and I looked into your eyes, my heart told me that you were going to seize me in your arms; and I knew that if you did I was ready to sink into your embrace and to give up everything for your sake. For you had swept me clean off my feet and had made me not care for my career, or for anything but you. But when you did n't--believe me, I don't know how or why it was--somehow the shock of your not doing it, when I was so ready to give my love--well, the tide seemed to turn then and go back. And now--I 'm on my feet again, and care tremendously about my profession and my career." He looked at her blankly, and as his lips twitched and moved she barely heard, "And I did n't--I barely kept myself from doing it, because it seemed unworthy--" She shrugged her shoulders and interrupted him, in a tone as low as his. "We who are strong can be taken only by a strength that is greater than ours." "Good-bye," he said, rising. "Either my love was not quite great enough, or my strength was too great. I will send the porter to carry your bags and help you to find your section in the other train. I shall stay here until to-morrow. Good-bye." His voice was very tender as he spoke the last word. She held out her hand, and he touched it with his lips. She pressed both hands upon her heart, which seemed bursting with cross-currents of feeling and desire. He was halfway down the aisle when she sprang to her feet and called to him to stop, to come back. He turned and saw her slowly take a step or two toward him. The intent gaze which he bent upon her wavered for an instant, and then she saw his lips grow tense and white. "No," he said deliberately, "I shall not come back. I do not want a wife who would bring to me any less than the greatest love of which she is capable. Good-bye, Dr. Black." He was gone, and Elizabeth, sinking back into her seat, saw him walk away into the hills. The tears gathered in her eyes. She watched him as his figure disappeared among the twilight shadows. "I wonder if it would have been different--it might have been different," she was thinking, "if he--he had been--as he was this afternoon." She mused a little longer and then her face brightened as she rose with a triumphant lifting of her head and a half-smile on her face. "And anyway," she said aloud, "he has my address!"
