"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!

She could not leave Uncle George, who was raving wildly, and yet it was necessary to obtain assistance somehow. Suddenly she remembered the distress signal. She must hoist it. How fortunate that Uncle George had once shown her how!

Ten minutes later there was a commotion over at Harbour Head where the signal was promptly observed, and very soon—although it seemed long enough to Mary Margaret—a boat came sailing over to the Big Dipper. When the men landed they were met by a very white-faced little girl who gasped out a rather disjointed story of a light that hadn't been lighted and an uncle with a broken leg and a sister tied in her chair, and would they please see to Uncle George at once, for she must go straight over to the other Dipper?

One of the men rowed her over, but before they were halfway there another boat went sailing across the harbour, and Mary Margaret saw a woman and two men land from it and hurry up to the house.

That is Mother and Uncle Martin, but who can the other man be? wondered Mary Margaret.

When she reached the cottage her mother and Uncle Martin were reading her note, and Nellie, just untied from the chair where she had been found fast asleep, was in the arms of a great, big, brown, bewhiskered man. Mary Margaret just gave one look at the man. Then she flew across the room with a cry of delight.
