"I _shall_ do it," was the confident answer. "I can't give money but I can give myself." There was a moment of silence; then Rose added softly, "I guess she loves you a lot, too, you are so good to ... to people, and do such wonderful things. When do you calculate to get married to her, Doctor Mac?" "Married?" he repeated in a startled voice, "Oh, some day, of course; but you know how terribly busy I am, and ..." He stopped, visualizing himself at that moment as he lolled indolently in the doorway of that mountain cabin, and wondering if the same thought were in her mind as was in his. At the same time came a welcome interruption in the appearance of a small child, brown as the proverbial berry, and bearing in her arms a large and rather dilapidated appearing doll. For an instant Donald failed to recognize her, and said, "Hello, here comes one of your little friends to see you, Smiles. Why, I do believe ... yes, it's Lou. Come along. You're not afraid of the doctor man who sent you that doll." Lou advanced, one finger in her mouth, the corners of which were lifting in a shy smile. Sensing the approach of another old friend, Mike bounded out of the doorway where he had lain panting in the shadow, and so energetic was his greeting that the child was very nearly upset by it, although as soon as she could regain her equilibrium she flung her little arms around the roughly coated neck, without a trace of fear. "Mike's got er broken leg," she announced. The words gave Donald a start until he saw that she was holding out to him her doll, one of whose limbs flapped about in piteous substantiation. "Kin yo' make hit well ergin?" Examining the injured member, whence the sawdust blood had issued through a deep incision in the cloth, Donald replied seriously, "It will require a rather serious operation, but I guess that I can mend it with the assistance of Nurse Smiles. We will have to sew up the wound and put the leg in splints." "Hit haint ergoin' ter hurt her much, air hit?" begged Lou, with all the solicitude of a young mother. "No. We'll give her an anesthetic--something to put her sound asleep--and I guess that she won't know anything about it." Rose joined them laughingly, bringing a threaded needle and some bits of cloth for stuffing and in a few minutes the operation was complete, even to the application of splints, roughly shaped by Donald's jack-knife. Throughout the process the physician explained each step to Rose, who cried as they finished, "Oh, I love to do it. It's lots more fun than book studying or weaving baskets." "Well, we might have a real lesson in 'first aid' this morning, if Lou can stay and be your little patient. Bring out that roll of bandages again."
