【正文】 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 the hungry little girls who gave awa y their breakfasts and contented themselves with bread and milk on Christmas morning. That39。s loving our neighbor better than ourselves, and I like it, said Meg, as they set out their presents while their mothe r 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 pleasureloving youth. When Mr. March lost his property in trying to help an unfortunate friend, the two oldest girls begged to be allowed to do som ething 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。, and her chief trouble was poverty. She found it harder to bear than the others because she could remember a time when home was beautiful, life full of ease and pleasure, and want of any kind unknown. She tried not to be envious or discontented, but it was very natural that the young girl should long for pretty things, gay friends, acplishments, and a happy life. At the Kings39。 she daily saw all she wanted, for the c hildren39。s older sisters were just out, and Meg caught frequent glimpses of dainty ball dresses and bouquets, heard lively gossip about theaters, concerts, sleighing parties, and merrymakings of all kinds, and saw money lavished on trifles which w ould have been so precious to her. Poor Meg seldom plained, but a sense of injustice made her feel bitter toward everyone sometimes, for she had not yet learned to know how rich she was in the blessings which alone can m ake life happy. Jo happened to suit Aunt March, who was lame and needed an active person to wait upon her. The childless old lady had offered to adopt one of the girls when the troubles came, and was much offended because her offer was declined. Other friends told the Marches that they had lost all chance of being remembered in the rich old lady39。s will, but the unworldly Marches only said... We can39。t give up our girls for a dozen fortunes. Rich or poor, we will keep together and be happy in one another. The old lady wouldn39。t speak to them for a time, but happening to meet Jo at at a friend39。s, something in her ical face and blunt manners struck the old lady39。s fancy, and she proposed to take her for a panion. This did not suit Jo at all, but she accepted the place since nothing better appeared and, to every one39。s surprise , got on remarkably well with her irascible relative. There was an occasional tempest, and once Jo marched home, declaring she couldn39。t bear it longer, but Aunt March always cleared up quic kly, and sent for her to e back again with such urgency that she could not refuse, for in her heart she rather liked the peppery old lady. I suspect that the real attraction was a large library of fine books, which was left to dust and spiders since Uncle March died. Jo remembered the kind old gentleman, who used to let her build railroads and bridges with his big dictionaries, tell her stories about queer pictures in his Latin books, and buy her cards of gingerbread whenever he met her in the street. The dim, dusty room, with the busts staring down from the tall bookcases, the cozy chairs, the globes, and best of all, the wilderness of books in which she could wander where she liked, made the library a region of bliss to her. The moment Aunt March took her nap, or was busy with pany, Jo hurried to this quiet place, and curling herself up in the e asy chair, devoured poetry, romance, history, travels, and pictures like a regular bookworm. But, like all happiness, it did not last long, for as sure as she had just reached the heart of the story, the swee test verse of a song, or the most perilous adventure of her traveler, a shrill voice called, Josy phine! Josy phine! and she had to leave her paradise to wind yarn, wash the poodle, or read Belsham39。s Essays by the hour together. Jo39。s ambition was to do something very splendid. What it was, she had no idea as yet, but left it for time to tell her, and meanwhile, found her greatest affliction in the fact that she couldn39。t read, run, and ride as much as she liked. A quick temper, sharp tongue, and restless spirit were always getting her into scrapes, and her life wa s a series of ups and downs, which were both ic and pathetic. But the training she received at Aunt March39。s was just what she needed, and the thought that she was doing something to support herself made her happy in spite of the perpetual Josy phine! Beth was too bashful to go to had been tr ied, but she suffered so much that it was given up, and she did her lessons at home with her father. Even when he went away, and her mother was called to devote her skill and energy to Soldiers39。 Aid Societies, Beth went faithfully on by herself and did the best sh
