YOUNG WOMEN who left their parents and homes between 1837 and 1850 to enroll at Mary Lyon's Mount Holyoke Female Seminary were beginning to plan consciously for a new kind of life. Their social origins indicate that their decisions to attend Mount Holyoke were schemes to widen their life chances.

Students mentioned planning whenever they wrote about Mary Lyon, and when they thought about their own futures. Helen Maria Graves, who attended Holyoke in 1848, was struck by what she called the "many little plans" Mary Lyon had devised to administer the Seminary.
