"But perhaps if they did—that is—if—" Miss Holbrook bit her lips and did not finish her sentence. She did not, indeed, say anything more for a long time. But she had not forgotten the story. David knew that, because later she began to question him carefully about many little points—points that he was very sure he had already made quite plain. She talked about it, indeed, until he wondered if perhaps she were going to tell it to some one else sometime. He asked her if she were; but she only shook her head. And after that she did not question him any more. And a little later David went home.

HEAVY HEARTS

For a week David had not been near the House that Jack Built, and that, too, when Jill had been confined within doors for several days with a cold. Jill, indeed, was inclined to be grieved at this apparent lack of interest on the part of her favorite playfellow; but upon her return from her first day of school, after her recovery, she met her brother with startled eyes.

"Jack, it hasn't been David's fault at all," she cried remorsefully. "He's sick."

"Sick!"

"Yes; awfully sick. They've had to send away for doctors and everything."

"Why, Jill, are you sure? Where did you hear this?"

"At school to-day. Every one was talking about it."
