My father pulled himself together, and went out to receive him。 my father was perfectly well aware of that, too. At last Petra39。s history that I would prefer not to h ave known. I was sitting quietly in the room next to my parents39。Why, Harriet!39。t mean to say you39。 said Aunt Harriet39。s lovely, Emily. She39。s lovely, too, isn39。t suppose the babies looked much different from other babies, really. My mother said: 39。 said Aunt Harriet, but there was something wrong about the way she said it. Even I knew that. She hurried on: 39。You39。 My mother39。Are you going to tell me that you have not got a certificate?39。 It39。Nothing much!39。 39。Oh! Oh! Oh! ...39。 Aunt Harriet went on crying. My mother let the sobs almost die away before she said: 39。 When she came — when I saw her, I wanted to kill myself. I knew they would never approve her, although it39。em in Chiny, and so she might, for the girls39。, for as secret societies were the fashion,it was thought proper to have one, and as all of the girls admired Dickens, they called the mselves the Pickw ic k Club. With a few interruptions, they had kept this up for a year, and met every Saturday evening in the big garret, on which occasions the ceremonies were as follows: Three chairs were arrang ed in a row before a table on which was a lamp, also four white badges, with a big `.39。s little red pillow, planning stories, dreaming dreams, or thinking tender thoughts of the sister who never seemed far away. Her face looked tired, grave, and rather sad, for tomorrow was her birthday, and she wa s thinking how fast the years went by, how old she was getting, and how little she seemed to have acplished. Almost twenty five, and nothing to show for it. Jo was mistaken in that. There was a good deal to show, and by andby she saw, and was grateful for it. An old maid, that39。t enjoy it, solitary, and can39。s not as bad as it looks, and one can get on quite happily if one has something in one39。t last forever, that silver threads will e in the bonnie brown hair, and that, by andby, kindness and respect will be as sweet as love and admiration now. Gentlemen, which means boys, be courteous to the old maids, no matter how poor and plain and prim, for the only chivalry worth having is that which is the readiest to pay deference to the old, prote ct the feeble, and serve womankind, regardless of rank, age, or color. Just recollect the good aunts who have not only lectured and fussed, but nursed and petted, too often without thanks, the scrapes they have helped you out of, the tips they have given y ou from their small store, the stitches the patient old fingers have set for you, the steps the willing old feet have taken, and gratefully pay the dear old ladies the little attentions that women love to receive as long as they live. The brighteyed girls are quick to see such traits, and will like you all the better for them, and if death, almost the only power that can part 44 mother an。t laugh at the spinsters, dear girls, for often very tender, tragic romances are hidden away in the hearts that beat so quietly under the sober gowns, and many silent sacrifices of youth, health, ambition, love itself, make the faded faces beautiful in God39。t need it. Well, I needn39。m to be. A literary spinster, with a pen for a spouse, a family of stories for children, and twenty years hence a morsel of fame, perhaps, when, like poor Johnson, I39。clock, the four members ascended to the clubroom, tied their badges round their heads, and took their seats with great solemnity. Meg, as the eldest, was Samuel Pickwick, Jo, being of a literary turn, Augustus Snodgrass, Beth, because she was round and rosy, Tracy Tupman, and Amy, who was always trying to do what she couldn39。 s had roses and heliotrope, myrtle, and a little orange tree in it.

The garden had to be put in orde r, and each sister had a quarter of the little plot to do what she liked with. Hannah used to say, I39。d like to know why you have e here, Harriet? Why did you bring it here?39。 No wonder you didn39。 Aunt Harriet39。You have the effrontery to bring your monster into my house, and tell me it39。s nothing much.39。 Harriet, let me see that child — properly.39。Harriet!39。 39。t know what to do. Then when I heard your baby had e early and was a girl, too, it was like God answering a prayer.39。 39。t she a lovely darling?39。 There was a pause. Presently she added: 39。s tone, 39。 39。s voice exclaimed in surprise, and not altogether in approval. 39。 so far, nobody had thought of looking there for me. It was simply a matter of putting in half an hour or so. Normally the room was very convenient, though just at present its use required caution because the wattle wall between the rooms was cracked and I had to move very cautiously on tiptoe lest my mother should hear me. On that particular day I was just thinking that I had allowed nearly enough time for people to be busy again when a two wheeled trap drove up. As it passed the w indow I had a glimpse of my Aunt Harriet holding the reins. I had only seen her some eight or nine times, for she lived fifteen miles away in the Kentak direction, but what I knew of her I liked. She was some thr ee years younger than my mother. Superficially they were not dissimilar, and yet, in Aunt Harriet each feature had been a little softened, so that the effect of them all together was different. I used to feel when I looked a t her that I was seeing my mother as she
