A new building was erected for the school and it was given the name of St. Cross. Mrs. Mills is said to have been very thorough in her instruction and management. The young ladies were trained in all the social etiquette of the day in addition to the more solid education imparted. Miss Mills (the elder daughter) assisted her mother with the music and modern languages. Miss Harriet Mills (the younger daughter) was more of a companion to the girls, and accompanied them on walks, in winter on the frozen river, in summer towards the plain.
