`` How long she does rub each spoon and glass . We never shall get done . What a fuss she makes with the napkins , laying them all even in the drawer . And now she 's at the salt-cellars , doing them just as mamma likes . I wish she 'd live here , and do my work for me . Why , what 's that ? '' And Polly stopped fretting to listen ; for she seemed to hear the sound of singing , -- so sweet , and yet so very faint she could catch no words , and only make out a cheerful little tune . `` Do you hear any one singing , mamma ? '' she asked . `` No : I wish I did . '' And mamma sighed ; for baby was poorly , piles of sewing lay waiting for her , Biddy was turning things topsy-turvy in the kitchen for want of a word from the mistress , and Polly was looking sullen . The little girl did n't say any more , but worked quietly and watched the shadow , feeling sure the faint song came from it . Presently she began to hum the tune she caught by snatches ; and , before she knew it , she was singing away like a blackbird . Baby stopped crying , and mamma said , smiling : `` Now I hear somebody singing , and it 's the music I like best in the world . '' That pleased Polly ; but , a minute after , she stopped smiling , for the shadow went and took baby , or seemed to , and Polly really did . Now , baby was heavy , and cross with its teeth ; and Polly did n't feel like tending it one bit . Mamma hurried away to the kitchen ; and Polly walked up and down the room with poor baby hanging over her arm , crying dismally , with a pin in its back , a wet bib under its chin , and nothing cold and hard to bite with its hot , aching gums , where the little teeth were trying to come through . `` Do stop , you naughty , fretty baby . I 'm tired of your screaming , and it 's high time you went to sleep . Bless me !
