"I am ready to go, Mr. Digby," Rotha said.

"And you will be a woman, and wise, and quiet?"

"I don't know!"

Mr. Digby thought it was not best to press matters further. He put Rotha into the wagon again and drove back to the hotel. Quiet she was, at any rate, now; he did not even see any more tears; but alas, of all the things in the world which she had been so glad to look at on the way down, she saw nothing on the way back. Driving or sailing, it was all the same; only when Mr. Digby put her into the omnibus at Whitehall he saw a flash of something like terror which crossed her face and left it blanched. But that was all.

He went into the invalid's room at Mrs. Marble's with trepidation. Rotha however was merely less effusive and more hasty than usual in her greetings to her mother, and after a kiss or two turned away "to get her things off," as she said. And when Mrs. Cord unluckily asked her in passing, if she had had a pleasant day? Rotha choked, but managed to get out that it had been "as good as it could be." What she went through in the little hall room which served for closet and wardrobe, no one knew; but Mr. Digby, who stayed purposely till she came back again, was reassured to see that she was perfectly quiet, and that she set about her wonted duties in a grave, collected way, more grave than usual, but quite as methodical. He went away sighing, at the same time with a relieved heart. One of the hard things he had had to do in his life, was over.

Mr. Digby however, as he walked homeward to his hotel, saw the difficulties yet in store for him. How in the world was he to perform his promise of taking care of this wildfire girl? Her aunt surely, would be the fittest person to be intrusted with her. If he only knew what sort of person Mrs. Busby really was, and how much of Mrs. Carpenter's story might have two sides to it? The lady was not in the city, or he would have been tempted to go and see her at once, for the purpose of studying her and gathering information. Nothing of the kind was possible at present; and he could only hope that Mrs. Carpenter's frail life would be prolonged until her sister's return to New York would lift, or might lift, one difficulty out of his path.

CHAPTER IX.

FORT WASHINGTON.

No such hope was to be realized. With all that care and kindness could do, the sick woman failed more and more. The great heats weakened her. The drives in the Park were refreshing, but alas, fatiguing, and sometimes had to be relinquished; and this happened again and again. Rotha behaved unexceptionably; was devoted to the service of her mother; untiring, and unselfish, and quiet; "another girl," Mrs. Cord said. Poor child! she was another girl in more ways than one; her fiery brightness of spirits was over, her cheeks grew thin, her eyes had dark rings round them, and their brown depths were heavy with a shadow darker yet. Energetic she was, as ever, but in a more staid and womanly way; the gladness of her doings was gone. Still, Mrs. Carpenter never saw her weep. In the evenings, or in the twilight, when there was nothing particular to be done, the child would nestle close to her mother, lay her head in her lap or rest it against her knee, and sit quiet. Still, at least, if not quiet; Mrs. Carpenter did sometimes fancy that she felt the drawing of a convulsive breath; but if she spoke then to Rotha, Rotha would answer with a specially calm and clear voice; and her mother did not get at her sorrow, if it were that which moved her. And Mrs. Carpenter was too weak now to try.

Mr. Digby came as usual, constantly. It was known to none beside himself, that he staid in town through the hot July and August days for this purpose solely. He saw that his sick friend grew weaker every day, yet he did not expect after all that the end would come so soon as it did. He had yet a lingering notion of bringing the sisters together, when Mrs. Busby should return. He was thinking of this one August afternoon as he approached the house. Mrs. Marble met him in the hall.
