Sidney sent Katie to ask Dr. Ed to come over after dinner. With the sunset Anna seemed better. She insisted on coming downstairs, and even sat with them on the balcony until the stars came out, talking of Christine's trousseau, and, rather fretfully, of what she would do without the parlors. “You shall have your own boudoir upstairs,” said Sidney valiantly. “Katie can carry your tray up there. We are going to make the sewing-room into your private sitting-room, and I shall nail the machine-top down.” This pleased her. When K. insisted on carrying her upstairs, she went in a flutter. “He is so strong, Sidney!” she said, when he had placed her on her bed. “How can a clerk, bending over a ledger, be so muscular? When I have callers, will it be all right for Katie to show them upstairs?” She dropped asleep before the doctor came; and when, at something after eight, the door of the Wilson house slammed and a figure crossed the street, it was not Ed at all, but the surgeon. Sidney had been talking rather more frankly than usual. Lately there had been a reserve about her. K., listening intently that night, read between words a story of small persecutions and jealousies. But the girl minimized them, after her way. “It's always hard for probationers,” she said. “I often think Miss Harrison is trying my mettle.” “Harrison!” “Carlotta Harrison. And now that Miss Gregg has said she will accept me, it's really all over. The other nurses are wonderful--so kind and so helpful.

Sidney might insist on the thing she always spoke of--that he visit the hospital; and he would meet her, face to face. He could have depended on a man to keep his secret. This girl with her somber eyes and her threat to pay him out for what had happened to her--she meant danger of a sort that no man could fight. “Soon,” said Sidney, through the warm darkness, “I shall have a cap, and be always forgetting it and putting my hat on over it--the new ones always do. One of the girls slept in hers the other night! They are tulle, you know, and quite stiff, and it was the most erratic-looking thing the next day!” It was then that the door across the street closed. Sidney did not hear it, but K. bent forward. There was a part of his brain always automatically on watch. “I shall get my operating-room training, too,” she went on. “That is the real romance of the hospital. A--a surgeon is a sort of hero in a hospital. You wouldn't think that, would you? There was a lot of excitement to-day. Even the probationers' table was talking about it. Dr. Max Wilson did the Edwardes operation.” The figure across the Street was lighting a cigarette. Perhaps, after all--
