"I have learned in these wanderings of mine that it is in the children this old world must place its trust. That if they want a better government they must give to the little ones all that is pure and clean and honest and good and see to it that they are happy. I feel like shouting it from the housetops--'Make them happy!' It doesn't take much. "I feel your big, wondering eyes on mine--you do not understand! Ah, well, girlie, all I mean is--romp and play--build up a strong little body for that heart of yours--see things that are clean and good, and whatever the game is--play square! "We cannot be grateful enough to the dear Lees for all they are doing for us. Try and return their kindness with loyalty. I will write later to Mrs. Lee in regard to the plans for the fall. Do whatever she thinks best. You will stay with them until I return. Just when that will be I cannot tell now, but you must be brave. Your courage helps me, too, my dear. "Sometimes, when my day's work is done and I can put it from my mind, I close my eyes and dream--dream of the little home we will build when I return: build--not in the old Square, that is gone except to memory--but in some sunny, open spot where we can live and work together and lead useful lives. It is a beautiful castle as I see it in my dreams--and beautiful with love. "I will send this letter with other papers to Washington and they will forward it to you. "Good-by, little soldier--I salute you, my General. "God keep you for "DADDY." The words rang through Keineth's heart like a song. She longed to pour out her joy in music, but Billy's voice came to her from below. "Ken, Ken." "Yes, Billy." "Come on, I'll play tennis with you! Bet you can beat me, too!" Keineth suddenly remembered Peggy's and Billy's rudeness. Perhaps Billy was trying to make amends. She really wanted to be alone with her letter a little longer, but if Billy wanted her to play! She felt proud, too, that he had asked her. Billy found less difficulty than he had anticipated in letting Keineth win the set. In fact, deep in his heart, he was not sure he had "let" her. For Keineth, fired with the joy within her, played brilliantly, flying over the court like a winged creature, returning Billy's serves with a surprising quickness and strength that completely broke down his boyish confidence in himself. "Thanks awfully--that _was_ fun," Keineth said as they sank down under a tree for a moment's rest. Though his plan had worked very well so far, Billy now felt at a loss to know how he ought to proceed. So, accepting her thanks with a brief nod, he bolted straight to the point. "Say, Ken, if you'll tell me about your father I promise on my scout's honor not to tell a soul! And you ought to tell me anyway, for didn't my dog save your life, and didn't I give you first aid or you might've died!"
