In the evening little Nan arrived. She was a very pretty, dimpled, brown-eyed creature, of just three years of age. She had all the imperious ways of a spoilt baby, and, evidently, fear was a word not to be found in her vocabulary. She clung to Hester, but smiled and nodded to the other girls, who made advances to her, and petted her, and thought her a very charming baby. Beside Nan, all the other little girls in the school looked old. She was quite two years the youngest, and it was soon very evident that she would establish that most imperious of all reigns--a baby reign--in the school.
