During 1833–1834 Frost's employment is specified as "Agent, Oneida Institute". By 1835 Frost had left Whitesboro for a pulpit in Elmira, (which he helped make an Underground Railroad center). His replacement, David Ogden, was not an abolitionist. This led to a withdrawal from the Whitesboro Presbyterian Church of "seventy-one communicant members, including most of the elders", to form a new Congregational church under Green's direction. As a result, "Green and his school [were left] with fewer and fewer friends"; he could no longer turn to churches for funding.
