Jessie opened her eyes widely, but she did not at once reply; she was not, strictly speaking, a clever girl, and did not at once grasp any new idea; our conversations were generally rather one-sided. Emma Hardy, who was our school wag, once observed that I used Jessie's brains as an airing-place for my ideas. Certainly Jessie listened more than she talked, but then, she listened so sweetly. "Of course, Alfred the Great, and Sir Philip Sidney, and Princess Elizabeth of France, and all the heroes and heroines of old time--all the people who did such great things and lived such wonderful lives--may be said to have had great minds; but I am not thinking about them. I want to know what makes a great mind, and how one is to get it. There is Carrie, now, you know how good she is; I think she may be said to have one." "Carrie--your sister?" "Why, yes," I returned, a little impatiently; for certainly Jessie could not think I meant that stupid, peevish little Carrie Steadman, the dullest girl in the school; and whom else should I mean, but Carrie, my own dear sister, who was two years older than I, and who was as good as she was pretty, and who set us all such an example of unworldliness and self-denial; and Jessie had spent the Christmas holidays at our house, and had grown to know and love her too; and yet she could doubt of whom I was speaking; it could not be denied that Jessie was a little slow. "Carrie is so good," I went on, when I had cooled a little, "I am sure she has a great mind. When I read of Mrs. Judson and Elizabeth Fry, or of any of those grand creatures, I always think of Carrie. How few girls of nineteen would deprive themselves of half their dress allowance, that they might devote it to the poor; she has given up parties because she thinks them frivolous and a waste of time; and though she plays so beautifully, mother can hardly get her to practice, because she says it is a pity to devote so much time to a mere accomplishment, when she might be at school, or reading to poor old Betty Martin." "She might do both," put in Jessie, rather timidly; for she never liked contradicting any of my notions, however far-fetched and ill-assorted they might be. "Do you know, Esther, I fancy your mother is a little sorry that Carrie is so unlike other girls; she told me once that she thought it such a pity that she had let her talents rust after all the money that had been spent on her education."
