ough time for people to be busy again when a twowheeled 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 three 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 d ifferent. I used to feel when I looked a t her that I was seeing my mother as she might have been — as, I thought, I would have liked her to be. She was easier to talk to, too。s voice exclaimed in surprise, and not altogether in approval. 39。 39。s tone, 39。 There was a pause. Presently she added: 39。t she a lovely darling?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。Harriet!39。 Harriet, let me see that child — properly.39。s nothing much.39。You have the effrontery to bring your monster into my house, and tell me it39。 Aunt Harriet39。 No wonder you didn39。d like to know why you have e here, Harriet? Why did you bring it here?39。t, because I thought perhaps I could saAs spring came on, a new set of amusements became the fashion, and the lengthening days gave long afternoons for work and play of all sorts. The garden had to be put in order, and each sister had a quarter of the little plot to do what she liked with.

My mother let the sobs almost die away before she said: 39。Oh! Oh! Oh! ...39。 39。Nothing much!39。 It39。Are you going to tell me that you have not got a certificate?39。 My mother39。You39。 said Aunt Harriet, but there was something wrong about the way she said it. Even I knew that. She hurried on: 39。t suppose the babies looked much different from other babies, really. My mother said: 39。s lovely, too, isn39。s lovely, Emily.
