Then Rose felt impelled to explain why she walked about London burdened with flower-pots and rolls of gauze. "I have just been to Covent Garden," she said. "I wished to get this pot of tulips--parrot tulips--yellow and scarlet, you know, to harmonize with a Chinese screen in a little picture I am painting. Then I had to go into 'Burnet's,' for 'Liberty's' is too far away, for some blue stuff of the right shade which I could drape into a frock for the little girl who is my model." "Are you fond of painting?" he caught her up, being to the full as willing to speak as she was. "So is my sister, and she also goes to 'Liberty's' for queer rags and tags. I suppose they are part of the amateur's stock-in-trade." "I am going to be a professional artist," said Rose again, with that proud little inflection of the voice. But all the effect which her communication had upon him was that he took it as an invitation, or at least as a warrant, for responsive confidences on his own part. "I am a doctor," he announced. "I have been entitled to write myself one for the last two months. I have just passed my final exams, and got my degree--stiffish work for a fellow who does not take to sapping as easily as to the air he breathes." "My father is a doctor," said Rose, brightly, with her tongue fairly loosened. "I forget whether he says examinations were easier or more difficult when he was young. He is Dr. Millar of Redcross." "Millar!" exclaimed the tall young man so excitedly, that he stopped short for an instant, in the middle of the dismally lashing rain, and looked at her with a gleam of delight in his blue eyes. "I thought so, I saw it at the first glance. You have a sister among the lady probationers at St. Ebbe's." "Yes--Annie," cried Rose, with equal ecstasy in the acquiescence; and she, too, stood still for a second in the rain. "Do you know St. Ebbe's? Have you seen Annie?" "I should think I do, I should think I have," he answered her fervently. "St. Ebbe's is my hospital. I have been 'walking it' for a year past. I was there to-day, and Miss Millar is well known all over the place. She is a great favourite with the matron, Mrs. Hull, and the house surgeon, and especially with the operating surgeon. He is always asking to have Miss Millar in his cases since that boy had his leg cut off." "I know, I know," chimed in Rose, "the little boy who begged you to wait till he had said his prayers, and when he could not do it for himself, Annie was able to do it for him. Now he is hopping about on his crutches quite actively and happily; and she has got him an engagement, to clean the knives and boots at Mrs. Jennings, the boarding-house in Welby Square where I stay. Isn't it too funny and nice that you should happen to have to do with St. Ebbe's and Annie?"
