“Not very,” said Patty, dropping her eyes before her father’s searching gaze.

Nothing more was said on the subject, but though Patty hated to do anything secretly, yet she felt she must continue her night work, as it was really her only chance.

So that night as she sat studying until nearly midnight, her door slowly opened, and Nan peeped in. She wore a kimono, and her hair was in a long braid down her back.

“Patty Fairfield,” she said, “go to bed at once! You ought to be ashamed of yourself, to sit up so late when you know your father doesn’t want you to.”

“Now, look here, Nan,” said Patty, talking very seriously, “I have to sit up late like this, because I can’t get a minute’s time through the day. You know how it is. There’s always company, or something going on, and I can’t wake up early in the morning, and I have to sit up late at night, even if it does make me tired and sleepy and good for nothing the next day. Oh, Nan, instead of hindering and making fun of me, and bothering me all you can, I think you might try to help me!”

Patty threw herself on her knees, and burying her face in Nan’s lap, burst into a convulsive flood of tears.

Nan was thoroughly frightened. She had never before seen Patty cry, and this was more than crying. It was almost hysterical.

Then, like a flash, Nan saw it all. Overwork and worry had so wrought on Patty’s nerves that the girl was half sick and wholly irresponsible for her actions.

With a ready tact, Nan patted the golden head, and gently soothed the excited child.

“Never mind, Patty, darling,” she said, “and try to forgive me, won’t you? I fear I have been rather blind to the true state of the case, but I see more plainly now, and I will help you, indeed I will. I will see to it that you shall have your hours for study just as you want them, and you shall not be interrupted. Dear little girl, you’re all tired out, and your nerves are all on edge, and no wonder. Now, hop along to bed, and you’ll see that things will go better after this.”
