of Whiteladies? He could not possibly know, or he would not give them up. And if he had a wife, she could not know, or she would never permit such a sacrifice. Miss Susan sat and thought till the moonlight disappeared from the window, and the Summer night felt the momentary chill which precedes dawn. She thought of it till her heart burned. No, she could not submit to this. In her own person she must ascertain if the story was true, and if the strangers really knew what they were doing. It took some time to move her to this resolution; but at last it took possession of her. To go and undo what Farrel-Austin had done, to wake in the mind of the heir, if this was the heir, that desire to possess which is dominant in most minds, and ever ready to answer to any appeal; she rose almost with a spring of youthful animation from her seat when her thoughts settled upon this conclusion. She put out her lamp and went to the window, where a faint blueness was growing--that dim beginning of illumination which is not night but day, and which a very early bird in the green covert underneath was beginning to greet with the first faint twitter of returning existence. Miss Susan felt herself inspired; it was not to defeat Farrel-Austin, but to prevent wrong, to do justice, a noble impulse which fires the heart and lights the eye. Thus she made up her mind to an undertaking which afterward had more effect upon her personal fate than anything else that had happened in her long life. She did it, not only intending no evil, but with a sense of what she believed to be generous feeling expanding her soul. Her own personal motives were so thrust out of sight that she herself did not perceive them--and indeed, had it been suggested to her that she had personal motives, she would have denied it strenuously. What interest could she have in substituting one heir for another? But yet Miss Susan’s blue eyes shot forth a gleam which was not heavenly as she lay down and tried to sleep. She could not sleep, her mind being excited and full of a thousand thoughts--the last distinct sensation in it before the uneasy doze which came over her senses in the morning being a thrill of pleasure that Farrel-Austin might yet be foiled. But what of that? Was it not her business to protect the old stock of the family, and keep the line of succession intact? The more she thought of it, the more did this appear a sacred duty, worthy of any labor and any sacrifice. CHAPTER VI.
