It was a long, hard row for the little twelve-year-old arms. Fortunately there was no wind. But thicker and thicker came the snow; finally the kitchen light was hidden in it. For a moment Mary Margaret's heart sank in despair; the next it gave a joyful bound, for, turning, she saw the dark tower of the lighthouse directly behind her. By the aid of her lantern she rowed to the landing, sprang out and made her boat fast. A minute later she was in the lighthouse kitchen. The door leading to the tower stairs was open and at the foot of the stairs lay Uncle George, limp and white. "Oh, Uncle George," gasped Mary Margaret, "what is the matter? What has happened?" "Mary Margaret! Thank God! I was just praying to Him to send somebody to 'tend the light. Who's with you?" "Nobody.... I got frightened because there was no light and I rowed over. Mother and Uncle Martin are away." "You don't mean to say you rowed yourself over here alone in the dark and snow! Well, you are the pluckiest little girl about this harbour! It's a mercy I've showed you how to manage the light. Run up and start it at once. Don't mind about me. I tumbled down those pesky stairs like the awkward old fool I am and I've broke my leg and hurt my back so bad I can't crawl an inch. I've been lying here for three mortal hours and they've seemed like three years. Hurry with the light, Mary Margaret." Mary Margaret hurried. Soon the Big Dipper light was once more gleaming cheerfully athwart the stormy harbour. Then she ran back to her uncle. There was not much she could do for him beyond covering him warmly with quilts, placing a pillow under his head, and brewing him a hot drink of tea. "I left a note for Mother telling her where I'd gone, Uncle George, so I'm sure Uncle Martin will come right over as soon as they get home." "He'll have to hurry. It's blowing up now ... hear it ... and snowing thick. If your mother and Martin haven't left the Harbour Head before this, they won't leave it tonight. But, anyhow, the light is lit. I don't mind my getting smashed up compared to that. I thought I'd go crazy lying here picturing to myself a vessel out on the reefs." That night was a very long and anxious one. The storm grew rapidly worse, and snow and wind howled around the lighthouse. Uncle George soon grew feverish and delirious, and Mary Margaret, between her anxiety for him and her dismal thoughts of poor Nellie tied in her chair over at the Little Dipper, and the dark possibility of her mother and Uncle Martin being out in the storm, felt almost distracted. But the morning came at last, as mornings blessedly will, be the nights never so long and anxious, and it dawned fine and clear over a white world. Mary Margaret ran to the shore and gazed eagerly across at the Little Dipper. No smoke was visible from Uncle Martin's house!
