"But I was a doctor, before I became a lover. My medical knowledge tells me that this is an opportunity of thoroughly fortifying my constitution, and (with God's blessing) of securing to myself reserves of health and strength which will take us together happily on the way to old age. Dear love, you must be my wife--not my nurse! There is the thought that gives me self-denial enough to let the Indian go away by himself."

Carmina answered this letter as soon as she had read it.

Before the mail could carry her reply to its destination, she well knew that the Indian messenger would be on the way back to his master. But Ovid had made her so happy that she felt the impulse to write to him at once, as she might have felt the impulse to answer him at once if he had been present and speaking to her. When the pages were filled, and the letter had been closed and addressed, the effort produced its depressing effect on her spirits.

There now appeared to her a certain wisdom in the loving rapidity of her reply.

Even in the fullness of her joy, she was conscious of an underlying distrust of herself. Although he refused to admit it, Mr. Null had betrayed a want of faith in the remedy from which he had anticipated such speedy results, by writing another prescription. He had also added a glass to the daily allowance of wine, which he had thought sufficient thus far. Without despairing of herself, Carmina felt that she had done wisely in writing her answer, while she was still well enough to rival the cheerful tone of Ovid's letter.

She laid down to rest on the sofa, with the photograph in her hand. No sense of loneliness oppressed her now; the portrait was the best of all companions. Outside, the heavy rain pattered; in the room, the busy clock ticked. She listened lazily, and looked at her lover, and kissed the faithful image of him--peacefully happy.

The opening of the door was the first little event that disturbed her. Zo peeped in. Her face was red, her hair was tousled, her fingers presented inky signs of a recent writing lesson.

"I'm in a rage," she announced; "and so is the Other One."

Carmina called her to the sofa, and tried to find out who this second angry person might be. "Oh, you know!" Zo answered doggedly. "She rapped my knuckles. I call her a Beast."

"Hush! you mustn't talk in that way."

"She'll be here directly," Zo proceeded. "You look out! She'd rap _your_ knuckles--only you're too big. If it wasn't raining, I'd run away." Carmina assumed an air of severity, and entered a serious protest adapted to her young friend's intelligence. She might as well have spoken in a foreign language. Zo had another reason to give, besides the rap on the knuckles, for running away.

"I say!" she resumed--"you know the boy?"

"What boy, dear?"

"He comes round sometimes. He's got a hurdy-gurdy. He's got a monkey. He grins. He says, _Aha--gimmee--haypenny._ I mean to go to that boy!"
