"True. I had forgotten that," said Keith.
One morning there came up a dense, soft, southern-sea fog, "The kind you can cut with a knife," Carrington said. It lasted for days, sweeping out to sea at night on the land breeze, and lying in a gray bank low down on the horizon, and then rolling in again in the morning enveloping the water and the island in a thick white cloud which was not mist and did not seem damp even, so freshly, softly salt was the feeling it gave to the faces that went abroad in it. Carrington and Keith, of course, must needs be out in it every moment of the time. They walked down the beach for miles, hearing the muffled sound of the near waves, but not seeing them. They sailed in it not knowing whither they went, and they drifted out at sunset and watched the land breeze lift it, roll it up, and carry it out to sea, where distant ships on the horizon line, bound southward, and nearer ones, sailing northward with the Gulf Stream, found themselves enveloped and bothered by their old and baffling foe. They went over to the reef every morning, these two, and bathed in the fog, coming back by sense of feeling, as it were, and landing not infrequently a mile below or above the lighthouse; then what appetites they had for breakfast! And, if it was not ready, they roamed about, roaring like young lions. At least that is what Melvyna said one morning when Carrington had put his curly head into her kitchen door six times in the course of one half hour.
The Sister shrank from the sea fog; she had never seen one before, and she said it was like a great soft white creature that came in on wings, and brooded over the earth. "Yes, beautiful, perhaps," she said in reply to Keith, "but it is so strange—and—and—I know not how to say it—but it seems like a place for spirits to walk, and not of the mortal kind."
They were wandering down the beach, where Keith had lured her to listen to the sound of the hidden waves. At that moment Carrington loomed into view coming toward them. He seemed of giant size as he appeared, passed them, and disappeared again into the cloud behind, his voice sounding muffled as he greeted them. The Sister shrank nearer to her companion as the figure had suddenly made itself visible. "Do you know it is a wonder to me how you have ever managed to live so far," said Keith smiling.
"But it was not far," said the little nun. "Nothing was ever far at the dear convent, but everything was near, and not of strangeness to make one afraid; the garden wall was the end. There we go not outside, but our walk is always from the lime-tree to the white rose-bush and back again. Everything we know there—not roar of waves, not strong wind, not the thick, white air comes to give us fear, but all is still and at peace. At night I dream of the organ, and of the orange-trees, and of the doves. I wake, and hear only the sound of the great water below."
"You will go back," said Keith.
He had begun to pity her lately, for her longing was deeper than he had supposed. It had its roots in her very being. He had studied her and found it so.
"She will die of pure homesickness if she stays here much longer," he said to Carrington. "What do you think of our writing down to that old convent and offering—of course unknown to her—to pay the little she costs them, if they will take her back?"
"All right," said Carrington. "Go ahead."
He was making a larger sail for his paroquet boat. "If none of you will go out in her, I might as well have all the sport I can," he said.
