I saw no more of them, and heard no further word; but I thought a great deal of the girl. Ah, me, if she could have been a young unknown, newly-found sister of my own, how warmly would I have welcomed her! How little should I have cared for the mud on her stockings; how closely would I have folded her in my arms; how anxious would I have been with Anne as to those damp clothes; what delight would I have had in feeding her, coaxing her, caressing her, and playing with her! There had seemed to belong to her a wholesome strong health, which it had made me for the moment happy even to witness. And then the sweet, eloquent anxiety of her voice,--“Oh, Anne, I do so wonder what he’s like!” While I heard her voice I had seemed to hear and know so much of her! And then she had passed out of my ken for ever! I thought no more about the duchess and the apple-woman, but devoted my mind entirely to the girl and her brother. I was persuaded that it must be a brother. Had it been a father there would have been more of awe in her tone. It certainly was a brother. Gradually, as the unforced imagination came to play upon the matter, a little picture fashioned itself in my mind. The girl was my own sister--a sister whom I had never seen till she was thus brought to me for protection and love; but she was older, just budding into womanhood, instead of running beside her nurse with twinkling legs. There, however, was the same broad, honest face, the same round eyes, the same strong nose and mouth. She had come to me for love and protection, having no other friend in the world to trust. But, having me, I proudly declared to myself that she needed nothing further. In two short months I was nothing to her,--or almost nothing. I had a friend, and in two little months my friend had become so much more than I ever could have been! These wondrous castles in the air never get themselves well built when the mind, with premeditated skill and labour, sets itself to work to build them. It is when they come uncalled for that they stand erect and strong before the mind’s eye, with every mullioned window perfect, the rounded walls all there, the embrasures cut, the fosse dug, and the drawbridge down. As I had made this castle for myself, as I had sat with this girl by my side, calling her the sweetest names, as I had seen her blush when my friend came near her, and had known at once, with a mixed agony and joy, how the thing was to be, I swear that I never once thought of the “Panjandrum.” I walked the whole round of the Regent’s Park, perfecting the building; and I did perfect it, took the girl to church, gave her away to my friend Walker, and came back and sobbed and sputtered out my speech at the little breakfast, before it occurred to me to suggest to myself that I might use the thing.
