"Some kinds of knowledge come to a man late in life," he continued softly; "since you and our darling have been with me I've learnt something that I was ignorant of. I'd read of it, not quite in an unbelieving way, but with the sort of doubt upon me that a story writ to amuse a child might bring. Since then I've known what happiness is."

"Did you never know before?" asked Sally wistfully.

"Never before, my child," he answered, huskily.

"Daddy," said Sally solemnly, "you mustn't make me cry. I ain't got time for it. There's the beef-tea to git ready, and the arrerroot----"

"You must compel that child to take rest," said Dr. Lyon to Seth later in the day, "or she'll break down. Human nature's limited, as a certain friend of mine used to say."

"I tried to persuade her," said Seth, "last night to go to bed, but she wouldn't; she cried and said it'd be easier for her to die than to sleep."

"She must be made to sleep," said the doctor. "If you come round to my place Ill give you something that will conquer her. She's a pearl, and must not be allowed to kill herself."

In accordance with the doctor's instructions Seth at midnight desired Sally to lie down on his bed; but Sally stoutly refused. Finding that his arguments were not strong enough to convince her that rest was necessary, he produced a paper written by Dr. Lyon to the effect that unless Sally Chester slept for four hours that night he would not come to see the Duchess again.

"So you see," said Seth, "you will hurt the Duchess by being obstinate."

"But you can tell Dr. Lyon that I've been asleep," persisted Sally.
