Amazed, speechless, overcome by wonder, Zillah could not say a word. She went to Mrs. Hart, folded her in her arms, and kissed over and over again the white lips of the woman who had once been dear to her in Chetwynde Castle.

"I do not understand it," said Mrs. Hart, feebly, and with an expression of deep amazement; "I do not comprehend all this at all. Here you all are, all of you whom I love--the only ones on earth whom I love. Here is my boy, my darling, whom I came to seek! Here is my sweet Zillah, who brightened my mournful life at Chetwynde Castle with her love and tenderness. And here I see my best friend, who came to save me from death and despair, and brought me here to life and joy and hope! What is the meaning of it all? My boy can not tell me. Say, my sweet Zillah, can not you tell me? Do you not know? Do you understand? Say, whose plan is it? Is it your plan? Who has brought us all together?"

"It is God," said Zillah, solemnly. "I do not understand how you came here. Let us thank God that you have found your friends."

She spoke at random; she knew not what to say. In her own dark perplexity she was unable to say any thing else; and when she saw that Mrs. Hart was equally perplexed, and turned to her for information, she could only find an answer in those words which were prompted by her heart. So she spoke, and she could say no more.

Nor could the others. All were silent. That white face looked wistfully from one to the other, with eager eyes, as though seeking from each some explanation; but none could give her that which she sought. In the faces that surrounded her she saw nothing else but a wonder which was fully equal to her own.

Obed Chute had now a fresh cause for bewilderment. For here was Zillah claimed fondly as a dear and loved friend by Mrs. Hart. Who was she? Was her mysterious story bound up in any way with the tragical life of the other who thus claimed her? He had been sufficiently astonished at the meeting between the woman whom he had rescued and his friend Windham; but now he saw his protégé, Miss Lorton, recognized by her as her dearest friend, and called by the most loving names--with an affection, too, which was fully returned by the one whom she thus addressed. What to think or to say he knew not. Of all the mysteries of which he had ever heard none equaled this, and it seemed to become more complicated every instant. He was at once perplexed by this insoluble problem, and vexed because it was insoluble. To his calm and straightforward mind nothing was so aggravating as a puzzle which could not be explained. He abhorred all mysteries. Yet here he found one full before him which baffled his utmost powers of comprehension--one, too, in which he himself was intermixed, and in which he saw Mrs. Hart and Windham and Miss Lorton all equally involved, and what was worse, equally in the dark.

But if Obed's bewilderment was great, what can be said of that which filled the mind of Lord Chetwynde? He saw his old nurse, whom he so deeply and even so passionately loved, turning away from himself to clasp in her arms, and to greet with the fondest affection, that beautiful girl who was dearer to him than any thing else in life. Mrs. Hart knew Miss Lorton! Above all, he was struck by the name which she gave her. She called her "Zillah!" More than this, she mentioned Chetwynde! She reproached this girl for running away from Chetwynde Castle! And to all this Miss Lorton said nothing, but accepted these fond reproaches in such a way that she made it seem as though she herself must once in very deed have lived in Chetwynde Castle, and fled from it. Mrs. Hart called her "Zillah!" To whom did that strange name belong? To one, and to one alone. That one was the daughter of General Pomeroy, whom he had married, and who was now his wife. That one he hated with a hate which no feeling of duty and no bond of gratitude could either lessen or overcome. Was he not married? Had he not seen that wife of his a thousand times? Had he not associated with her at Chetwynde Castle, at Lausanne, on the road, and in Florence? What madness, what mockery was this? It would seem as though Mrs. Hart had mistaken Miss Lorton for that detested wife who stood between him and his love. But how could such a mistake be made? True, the complexion of each was dark, and the hair of each was black, and the forms and figures were not unlike; but the features were widely different; the large, soft, loving eyes of Miss Lorton were not like those gleaming, fiery orbs that he had seen in the woman whom he thought his wife; and the expression of the face in each was as unlike as possible. Could Mrs. Hart be in a delirium? She must be mad! But then the worst of it was, that if she were mad Miss Lorton must be mad also.

"Where am I?" said Mrs. Hart, rousing herself, and breaking in upon Lord Chetwynde's thoughts. "It seems to me that I have suddenly escaped from a hell, where I have been living, and have come into heaven. Where am I? How is it that I find myself among those whom I hold most dear? Oh, my old friend! my savior! my benefactor! tell me, are you really a living being?"

"Nothing shorter," replied Obed, solemnly, "to the best of my knowledge and belief, though at the present moment I feel inclined to doubt it."

"My boy, give me your hand. Do I really hold it? Am I not dreaming?"
