How nice my handkerchiefs look, don39。t they? Hannah washed and ironed them for me, and I marked them all myself, said Beth, looking proudly at the somewhat uneven letters which had cost her such labor. Bless the child! She39。s gone and put `Mother39。 on them instead of `M. March39。. How funny! cried Jo, taking one up. Isn39。t that right? I thought it was better to do it so, because Meg39。s initials are ., and I don39。t want anyone to use these but Marmee, said Beth。, looking troubled. It39。s all right, dear, and a very pretty idea, quite sensible too, for no one can ever mistake now. It will ple ase her very much, I know, said Meg, with a frown for Jo and a smile for Beth. There39。s Mother. Hide the basket, quick! cried Jo, as a door slammed and steps sounded in the hall. Amy came in hastily, and looked rather abashed when she saw her sisters all waiting for her. Where have you been, and what are you hiding behind you? asked Meg, surprised to see, by her hood and cloak, that lazy Amy had been out so early. Don39。t laugh at me, Jo! I didn39。t mean anyone should know till the time came. I only meant to change the little bottle for a big one, and I gave all my money to get it, and I39。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 eff ort to fet herself that Meg hugged her on the spot, and Jo pronounced her `a trump39。, while Beth ran to the window, and picked her finest rose to ornament the stately bottle. You see I felt ashamed of my present, after reading and talking about being good this morning, so I ran round the corner and changed it the minute I was up, and I39。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 Christmas, little daughters! I39。m glad you began at once, and hope you will keep on. But I want to say one word before we sit down. Not far away from here lies a poor woman with a little newborn baby. Six children are huddled into one bed to keep from freezing, for they have no fire. There is nothing to eat over there, and the oldest boy came to tell me they were suffering hunger and c old. My girls, will you give them your breakfast as a Christmas present? They were all unusually hungry, having waited nearly an hour, and for a minute no one spoke, only a minute, for Jo exclaimed impetuously, 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。d do it, said Mrs. March, smiling as if satisfied. You shall all go and help me, and when we e back we will have bread and milk for breakfast, and make it up at dinnertime. They were soon ready, and the procession set out. Fortunately it was early, and they went through back streets, so few people saw them, and no one laughed at the queer pa rty. A poor, bare, miserable room it was, with broken windows, no fire, ragged bedclothes, a sick mother, wailing baby, and a group of pale, hungry children cuddled under one old quilt, trying to keep warm. How the big eyes stared and the blue lips smiled as the girls went in. Ach, mein Gott! It is good angels e to us! said the poor woman, crying for joy. Funny angels in hoods and mittens, said Jo, and set them to laughing. In a few minutes it really did seem as if kind spirits had been at wor k there. Hannah, who had carried wood, made a fire, and stopped up the broken panes with old hats and her own cloa k. Mrs. March gave the mother tea and gruel, and forted her with promises of help, while she dressed the little baby as tenderly as if it had been her own. T he girls meantime spread the table, set the children round the fire, and fed them like so many hungry birds, laughing, talking, and trying to understand the funny broken English. Das ist gut! Die Engel kinder! cried the poor things as they ate and warmed their purple hands at the fortable blaze. T he girls had never been c alled angel children before, and thought it very agreeable, especially Jo, who had been considered a `Sancho39。 ever since she was born. That was a very happy breakfast, though they didn39。t ge t any of it. And when they went away, leaving fort behind, I think there were not in all the city four merrier people than
