Then Maude turned to Carr, with a very professional air, as she turned back the ruffles from her wrists. "I am going to set your
leg," she said, "and I'm thinking what I can get for splints. I hope Lizzie will send a good, new sheet for bandages. Now, Sandy boy, put your mattress here, and you must take Mr. Carr by the shoulders and help him on to it while I hold his poor leg so it won't hurt more than can be helped. Good thing we are strong, Sandy!" —“A Century Ride,”
