After five years, she formed the plan and design of extensively improving female education, chiefly by inducing some state government to establish a female seminary for liberal yet feminine education, and committed her plan to writing. She introduced studies into her school before untaught to females. She had five young ladies in her school of seventy from Waterford, N. Y., to which place she was invited, their leading men to present, 1818, her plan to the legislature of New York. They were to do it, if Gov. Clinton approved: he did so, and brought forward the subject in his message.
