I 'll be back as quickly as I can , and Mother and Uncle Martin will soon be here . You wo n't be afraid to stay alone , will you , dearie ? You must n't be afraid , because I have to go . And , Nellie , I 'm going to tie you in your chair ; it 's necessary , because I ca n't lock the door , so you must n't cry ; nothing will hurt you , and I want you to be a brave little girl and help sister all you can . '' Nellie , too sleepy and dazed to understand very clearly what Mary Margaret was about , submitted to be wrapped up in quilts and bound securely in her chair . Then Mary Margaret tied the chair fast to the wall so that Nellie could n't upset it . That 's safe , she thought . Nellie ca n't run out now or fall on the stove or set herself afire . Mary Margaret put on her jacket , hood and mittens , and took Uncle Martin 's lantern . As she went out and closed the door , a little wail from Nellie sounded on her ear . For a moment she hesitated , then the blackness of the Big Dipper confirmed her resolution . She must go . Nellie was really quite safe and comfortable . It would not hurt her to cry a little , and it might hurt somebody a great deal if the Big Dipper light failed . Setting her lips firmly , Mary Margaret ran down to the shore . Like all the Harbour girls , Mary Margaret could row a boat from the time she was nine years old . Nevertheless , her heart almost failed her as she got into the little dory and rowed out . The snow was getting thick . Could she pull across those black two miles between the Dippers before it got so much thicker that she would lose her way ? Well , she must risk it .
She had set the light XXXXX the kitchen window ; she must keep it fair behind her and then she would land on the lighthouse beach .
