"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. "When you haven't?" interrupted Seth, with a touch of his old humour. "O, Sally, Sally! would you teach me to tell lies at my time of life? Come now, my dear, be good and reasonable. I'll watch by our treasure till you wake up; I know you wouldn't trust her with anybody else." "No, that I wouldn't; and if she asks for me you'll call me at once?" "Yes, you may trust me, Sally." With that Sally yielded, and, with small persuasion, drank the draught prepared for her. "I'll go in five minutes," she said, sitting on a stool by the bedside, and gazed lovingly on the sleeping Duchess. "All right," said Seth, who was sitting on a chair close to her; "rest your head on my knee, dear child." With a grateful sigh, Sally obeyed, and clasped Seth's hand, which was lying with light touch on her neck. Thus, with tired eyes watching the Duchess's face, she remained for two or three minutes, when the narcotic she had taken overpowered her, and she sank to sleep. Seth raised her softly in his arms, and placed her in his bed, covering her up warm, and kissing her before he resumed his seat at the Duchess's bedside. The child had been peculiarly restless all the evening, but was now in a calmer state. For an hour Seth kept his watch faithfully, and without moving from his seat; but some anxiety with reference to Sally caused him to step softly to her side.
