Her corner was an adjoining section of the garret, boarded up, wall-papered, and furnished for those who visited the Farm Hospital on tour of inspection or to see some sick friend or relative, or escort some haggard convalescent to the Northern home.

Celia had brought a whole trunkful of fresh gingham clothes and aprons, and Ailsa could not discover exactly why, until, on the day following her arrival, she found Celia sitting beside the cot of a wounded Louisiana Tiger, administering lemonade.

"Dearest," whispered Ailsa that night, "it is very sweet of you to care for your own people here. We make no distinction, however, between Union and Confederate sick; so, dear, you must be very careful not to express any—sentiments."

Celia laughed. "I won't express any sentiments, Honey-bee. I reckon I'd be drummed out of the Yankee army." Then, graver: "If I'm bitter—I'll keep it to myse'f."

"I know, dear. . . . And—your sympathies would never lead you—permit you to any—indiscretion."

"You mean in talking—ahem!—treason—to sick Confederates? I don't have to, dear."

"And. . . you must never mention anything concerning what you see inside our lines. You understand that, of course, don't you, darling?"

"I hadn't thought about it," said Celia musingly.

Ailsa added vaguely: "There's always a government detective hanging around the hospital."

Celia nodded and gazed out of the open window. Very far away the purple top of a hill peeped above the forest. Ailsa had told her that a Confederate battery was there. And now she looked at it in silence, her blue eyes very soft, her lips resting upon one another in tender, troubled curves.
