The moon was rising before the afterglow had wholly faded. A light breeze made the delicate green leaves rustle on a hundred nearby trees, the magnolias were in bloom over the entire island, scenting the night air with their heavy, tropical fragrance.

In the moonlight and the last of the purple twilight, David Hale was devoting little attention to these details. He was thinking with the concentration over which he had a special mastery, of something he wished to say to Bettina Graham and of how he had best say it.

She waved a long blue scarf as she came running down the path toward him.

"I did not keep you waiting long, David, did I? I am sorry you must go to-morrow, but then the house party will break up in another week or ten days and I am returning to New York. After all, it is a shorter journey for you to come back to the 'House by the Blue Lagoon' than for me, and you know mother and Marguerite Arnot are always pleased to see you. I wish I could reach here so easily; for a number of reasons it is going to be very hard to leave the island, our island. I have a fashion of saying 'our island' over again to myself every now and then because it seems so incredible that we can own such an exquisite spot and that it is no farther away from the outside world. Why, except that it is not tropical, we might almost deceive ourselves into believing that we were on one of the south sea islands!"

"Then why do you go, Bettina, unless you wish? There certainly can be no other reason and your mother will be distressed at your departure. It is so impossible for me to understand your point of view. Your home is here and no other place can be so beautiful!"

"I know, David," Bettina answered gently, "and yet I have tried so often to explain to you and to other people: beautiful as this place is and loving it as I do, yet my work and life are no more here than your own. You are going back to Washington, David; you are very ambitious and some day intend to have a political career. Suppose this were your home instead of mine, would you stay here always? Would you give up your work and your ambition and your future to live in an island of dreams?

"No, of course you would not? Then why do you think I should? Oh, I know the answer, I have gone into the subject so many times--because I am a girl and there is no reason why I should devote myself to social work, when my father is a man of prominence and some wealth and my mother all that is sweet and charming and popular. I am not going to talk about myself, only you do know my reason and you could understand my point of view if you would make the effort. Instead of caring less for my work after a few months of effort and experience, I care more than at the beginning."

"I am sorry, Bettina."

Bettina laughed.

"Why should you be? Mother and father are becoming more reconciled."
