But it was too late for that. The young man, at first almost as much startled as his companion at the uncanny apparition, naturally experienced a revulsion of indignation at such an extraordinary interruption to his tete-a-tete, and stepped up to Mr. Morgan as if about to inflict summary chastisement. But perceiving that he had to do with an elderly man, he contented himself with demanding in a decidedly aggressive tone what the devil he meant by such a performance. Mr. Morgan stared at him without seeing him, and evidently did not take in the words. He merely gasped once or twice, and looked as if he had fainted away on his feet. His blank, stunned expression showed that his faculties were momentarily benumbed by the shock. Miss Rood felt as if she should die for the pity of it as she looked at his face, and her heart was breaking for grief as she sought to mollify the young man with some inarticulate words of apology, meanwhile still endeavoring to draw Mr. Morgan away. But at this moment the girl, recovering from her panic, came up to the group and laid her hand on the young man's arm, as if to check and silence him. It was evident that she saw there was something quite unusual in the circumstances, and the look which she bent upon Mr. Morgan was one of sympathy and considerate interrogation. But Miss Rood could see no way out of their awkward situation, which grew more intolerable every moment as they thus confronted each other. It was finally Mr. Morgan's voice, quite firm, but with an indescribable sadness in the tones, which broke the silence: "Young people, I owe you an apology, such as it is. I am an old man, and the past is growing so heavy that it sometimes quite over-balances me. My thoughts have been busy to-night with the days of my youth, and the spell of memory has been so strong that I have not been quite myself. As you came in view I actually entertained the incredible idea for a moment that somehow I saw in you the materialized memories of myself and another as we once walked this same path." The young man bowed as Mr. Morgan ended in a manner indicating his acceptance of the apology, although he looked both amazed and amused. But the explanation had a very different effect upon the girl at his side. As she listened her eyes had filled with tears and her face had taken on a wonderfully tender, pitiful smile. When he ended speaking, she impulsively said, "I'm so sorry we were not what you thought us! Why not pretend we are, to-night at least? We can pretend it, you know. The moonlight makes anything possible;" and then glancing at Miss Rood, she added, as if almost frightened, "Why, how much we look alike! I'm not sure it isn't true, anyway."
