When Etienne had fallen asleep Edna bore him into the back room, and Robert went and lifted the mosquito bar that she might lay the child comfortably in his bed. The quadroon had vanished. When they emerged from the cottage Robert bade Edna good-night.
"Do you know we have been together the whole livelong day, Robert--since early this morning?" she said at parting.
"All but the hundred years when you were sleeping. Goodnight."
He pressed her hand and went away in the direction of the beach. He did not join any of the others, but walked alone toward the Gulf.
Edna stayed outside, awaiting her husband's return. She had no desire to sleep or to retire; nor did she feel like going over to sit with the Ratignolles, or to join Madame Lebrun and a group whose animated voices reached her as they sat in conversation before the house. She let her mind wander back over her stay at Grand Isle; and she tried to discover wherein this summer had been different from any and every other summer of her life. She could only realize that she herself--her present self--was in some way different from the other self. That she was seeing with different eyes and making the acquaintance of new conditions in herself that colored and changed her environment, she did not yet suspect.
She wondered why Robert had gone away and left her. It did not occur to her to think he might have grown tired of being with her the livelong day. She was not tired, and she felt that he was not. She regretted that he had gone. It was so much more natural to have him stay when he was not absolutely required to leave her.
As Edna waited for her husband she sang low a little song that Robert had sung as they crossed the bay. It began with "Ah! Si tu savais," and every verse ended with "si tu savais."
