The change into a home atmosphere and the loving care with which he was surrounded, worked wonders in Jim, and when the judge decided that he should remain where he was, and not be sent to any other home, the boy grew stronger by the hour. Then Laura had her hands full to keep him happily occupied; for after a while, in spite of auto rides and visits to the Zoo--in spite of books and games and picture puzzles--sometimes she thought he seemed not quite happy, and she puzzled over the problem, wondering what she had left undone. When one day she found him watching some boys playing in a vacant lot, the wistful longing in his eyes was a revelation to her. "Of course, it is boys he is longing for--boys and out-of-door fun. I ought to have known," she said to herself, and at once she called Elsie Harding on the telephone. "Will you ask your brother Jack if he will come here Saturday morning and see Jim? Tell him it is a chance for his 'one kindness,' a kindness that will mean a great deal to my boy." "I'll tell him," Elsie promised. "I know he'll be glad to go if he can." Laura said nothing to Jim, but when Jack Harding appeared, she took him upstairs at once. Jim was standing at the window, watching two boys and a puppy in a neighbouring yard. He glanced listlessly over his shoulder as the door opened, but at sight of a boy in Scout uniform, he hurried across to him, crying out, "My! But it's good to see a boy!" Then he glanced at Laura, the colour flaming in his face. Would she mind? But she was smiling at him, and looking almost as happy as he felt. "This is Jack Harding, Elsie's brother," she said, "and, Jack, this is my boy Jim. I hope he can persuade you to stay to lunch with him." Then she shut the door and left the two together. When she went back at noon, she found the boys deep in the mysteries of knots. Jim looked up, his homely little face full of pride. "Jack is learning me to tie all the different knots," he cried, "and he's going to learn me ['teach,' corrected Jack softly]--yes, teach me everything I'll have to know before I can be a Scout. Jack's a second class Scout--see his badge? We've had a bully time, haven't we, Jack?" Suddenly his head went down and his heels flew into the air as he turned a somersault. Coming right end upwards again, he looked at Laura with a doubtful grin. "I--I didn't mean to do that," he stammered. "It--just did itself--like----" Jack's quick laugh rang out then. "I know. You had to get it out of your system, didn't you?" he said with full understanding. That was a red-letter day to Jim. He kept his visitor until the last possible moment, and stood at the window looking after him till the straight little figure in khaki swung around a corner and was gone. Then with a long happy breath he turned to Laura and said, half apologetically, half appealingly, "You see a fellow gets kind o' hungry for boys, sometimes. You don't mind, do you, Miss Laura?"
