"But you must," said Caroline quietly. She felt that the child's illness and the terrible cause of it were wrecking Mrs. Blackburn's health as well as her happiness.

"Of course, I must try to take care of myself because in the end it will be so much better for Letty." As she answered, Angelica slipped her feet into a pair of embroidered blue silk mules, and rising slowly from her lace pillows, stood up on the white rug in front of the fire. Though she was not tall, her extraordinary slenderness gave her the effect of height and the enchanting lines of one of Botticelli's Graces. "With you in the house I feel that everything will be easier," she added, after a minute in which she gazed down at the new nurse with a thoughtful, appraising look.

"It will be as easy as I can make it. I will do everything that I can." The words were not spoken lightly, for the opportunity of service had brought a glow to Caroline's heart, and she felt that her reply was more than a promise to do her best—that it was a vow of dedication from which only the future could release her. She had given her pledge of loyalty, and Mrs. Blackburn had accepted it. From this instant the bond between them assumed the nature and the obligation of a covenant.

A smile quivered and died on Angelica's lips, while the pathos in her expression drew the other to her as if there were a visible wound to be healed. "You will be a blessing. I can tell that when I look at you," she murmured; and her speech sounded almost empty after the overflowing sympathy of the silence. To Caroline it was a relief when the housekeeper called to her from the doorway, and then led her upstairs to a bedroom in the third storey.

It was a delightful room overlooking the circular drive, and for a minute they stood gazing down on the lawn and the evergreens.

"Everything is so lovely!" exclaimed Caroline presently. One could rest here, she thought, even with hard work and the constant strain, which she foresaw, on her sympathies.

"Yes, it is pretty," answered the housekeeper. Already Mrs. Timberlake had proved that, though she might be the salt of the earth, she was a taciturn and depressing companion—a stranded wreck left over from too voluble a generation of women.

"And I never saw any one lovelier than Mrs. Blackburn," said Caroline, "she looks like an angel."

"Well, I reckon there is mighty little you can say against Angelica's looks unless your taste runs to a trifle more flesh," responded Mrs. Timberlake drily.

"She ought to be happy," pursued Caroline, with a feeling that was almost one of resentment. "Anyone as beautiful as that ought to be happy."
