Hannah washed and ironed them for me, and I ma rked them all myself, said Beth, looking proudly at the somewhat uneven letters which had cost her such labor. Bless the child! She39。 on them instead of `M. March39。t that right? I thought it was better to do it so, because Meg39。t want anyone to use these but Marmee, said Beth。s all right, dear, and a very pretty idea, quite sensible too, for no one can ever mistake now. It will please her very much, I know, said Meg, with a frown for Jo and a smile for Beth. There39。t laugh at me, Jo! I didn39。m truly trying not to be selfish any more. As she spoke, Amy showed the handsome flask w hich replaced the cheap one, and looked so earnest and humble in her little effo rt to fet herself that Meg hugged her on the spot, and Jo pronounced her `a trump39。m so glad, for mine is the handsomest now. Another bang of the street door sent the basket under the sofa, and the girls to the table, eager for breakfast. Merry Christmas, Marmee! Many of them! Thank you for our books. We read some, and mean to every day, they all cried in chorus. Merry Chr istmas, little daughters! I39。m so glad you came before we began! May I go and help carry the things to the poor little children? asked Beth eagerly. I shall take the cream and the muffings, added Amy, heroically giving up the article she most liked. Meg was already covering the buckwheats, and piling the bread into one big plate. I thought you39。 ever since she was born. That was a very happy breakfast, though they didn39。s loving our neighbor better than ourselves, and I like it, said Meg, as they set out their presents while the ir mother was upstairs collecting clothes for the poor Hummels. Not a very splendid show, but there was a great deal of love done up inster an encouraging pat on the shoulder as they parted for the day, each going a different way, each hugging her little warm turnover, and each trying to be cheerful in spite of wintry weather, hard work, and the unsatisfied desires of pleasure loving youth. When Mr. March lost his property in trying to help an unfortunate friend, the two oldest girls begged to be allowed to do something toward their ow n support, at least. Believing that they could not begin too early to cultivate energy, industry, and independence, their parents consented, and both fell to work with the hearty good will which in spite of all obstacles is sure to succeed at last. Margaret found a place as nursery governess and felt rich with her small salary. As she said, she was `fond of luxury39。 she daily saw all she wanted, for the childr
