Miss Mills assisted her mother with the music and modern languages.

Miss Harriet Mills, being younger, was more of a companion to the girls, and accompanied them on walks, in winter on the frozen river, in summer towards the plain, and unless her maturer years belie the record of her girlhood we may imagine she was a very lively and agreeable companion.

In addition to her regular school duties Mrs.Mills had a class for girls who were beyond school age.

She also gave assistance in Sunday school work.
The pianos used in these schools had to be brought by sea, river and portage by way of Hudson Bay; one of them is still in possession of Miss Lewis, St.James.The teachers from England had to traverse the same somewhat discouraging route in coming into the Settlement.

Miss Mills, who came alone a little later than her mother and sister, traveled from York Factory under the care of Mr.Thomas Sinclair.
