And suddenly Sylvia did understand, and came and put her arms around the other woman with real joy and affection.

"If it will only be a boy," sighed Jeanette. "It is dreadful to be a woman in this world, and Dad would like it so, and so would Francis."

When she returned to the hotel again there was a letter from Jack waiting for Sylvia, the second only since she had come to New York. The first had been in response to her telegram announcing that Phil was surely out of danger. It had been a very brief letter, expressing his relief and pleasure at the good news of Phil's recovery. "And Sylvia, Belovedest," it had added, "don't forget I meant just what I said that day. Don't bother about me. I don't count. Nothing counts except your being happy. I believe I have always known it was Phil you really cared for. Anyway, I know it now. You have always been an angel of goodness to me and I am grateful. It has been just Jack and Jill going up the hill. Jack fell down and broke his crown all right, but there is no reason in the world why Jill should come tumbling after. And in order to prevent such a disaster the best thing Jack can say is good-by."

Sylvia had written back a long, affectionate and remorseful letter blaming herself wholly and severely and accepting his proffered release from their engagement. She had not heard from him again until now. Consequently she tore open the letter with some trepidation.

"Dear Sylvia,"--So it ran--

"I am sailing to-morrow to join the American Ambulance Field Service in France. It isn't a new notion. It has been in the back of my brain a long time. I should have gone in December if you had refused me then. I am not much good at anything but driving a car. I stuck to the business because you wanted me to but my heart wasn't in it. Dad understands, and is perfectly willing I should go. Don't misunderstand me, please, sweetheart. I am not doing this for gallery play or to work on your feelings. And I'm not going to talk any tommyrot about my life being spoiled and wanting to throw it away. I don't want to throw it away. I want to find it if I can over there. It seems to me France ought to drive whip and spur into any chap and make a man of him. Anyway, I'm going to have a try at it. Of course there is a little danger--not much. You must not worry. Danger agrees with me, and I'm a lucky chap in everything but love. Best wishes to old Phil. Remember that means in everything.

"I would have come to say good-by in person, but it took a little more nerve than I have just now. It was easier for both of us for me to make a quiet getaway. Wish me luck, Sylvia.

"Yours, as always,

"JACK."

Sylvia read the letter, dazed, troubled but by no means surprised. It was like Jack to do the gallant, generous, splendid, impulsive thing. As she finished she made a rapid calculation. "I sail to-morrow." That must mean to-day. He was already gone. Somewhere out beyond the harbor his ship was plowing its way toward France. The tears came into her eyes. Jack was very dear to her. Why, oh why had she driven him to this unnecessary danger, this fearful carnage field overseas? And yet was he not right? Would he not find something worth the risk in the stern realities of that glorious and tragic country he went to aid? That he had not gone into it lightly she saw. He had counted the possible cost as any man who was not a fool must count it. But he had not gone in bravado or in bitterness. He had taken pains to show her that. He had gone simply, in quiet earnest to prove himself, not to throw away his life recklessly but to find it as he said. Dear Jack! No wonder Sylvia's eyes were wet as she folded his letter and put it back in its envelope.
