The next hour was occupied in necessary details which had not hitherto occurred to him. The clothing of the children had to be exchanged. It was done; the dead was arrayed as the living, the living as the dead. Mere words are powerless to express Aaron's feelings as he performed this task, and when he placed the living, breathing babe in the bed in which Rachel lay, and took his own dead child to an adjoining room and laid it in his own bed, scalding tears ran down his cheeks. "God forgive me, God forgive me!" he murmured again and again. He knelt by Rachel's bed and buried his face in his hands. He had committed himself to the deception; there was no retreat now. For weal or woe the deed was done. And there was so much yet to do--so much that he had not thought of! Each false step he was taking was leading to another as false as that which preceded it. But if the end justified the means--if he did not betray himself--if Rachel, awaking, suspected nothing, and heard the voice of the babe by her side, without suspecting that it was not her own, why, then, all would be well! And all through his life, to his last hour, he would endeavor to make atonement for his sin. He inwardly acknowledged it now, without attempting to gloss it over. It was a sin; though good would spring from it, though a blessing might attend it, the act was sinful. His painful musings were arrested by a knock at the street door. With a guilty start he rose to his feet and gazed around with fear in his eyes. What did the knock portend? Was it in some dread way connected with his doings? The thought was harrowing. But presently he straightened himself, set his lips firmly, and went downstairs to attend to the summons. CHAPTER XXIII. PLUCKED FROM THE JAWS OF DEATH. Mr. Moss stood at the street door, bearing in his arms the little iron safe which Dr. Spenlove, at the intercession of the mother who had consented to part with her child, had intrusted to him. "In my excitement, Cohen," he commenced before Aaron could speak, "something slipped my memory when we were talking together. I rapped softly at first, fearing to disturb Rachel, but no one answering, I had to use the knocker. I hope I have not disturbed her." "She is sleeping peacefully," replied Aaron, "and is taking a turn for the better, I am thankful to say. To-morrow, I trust, all danger will be over. Come in." He closed the door gently, and they entered the parlor. "I have come back about this little safe," said Mr. Moss, depositing it on the table; "it belongs to the task I undertook. The mother of the babe made it a stipulation that whoever had the care of the child should receive the safe, and hold it in trust for her until she claimed it." "But I understood," said Aaron in apprehension, "that the mother had no intention of claiming her child."
