Peck became active in establishing Bible societies and Sunday School associations. Distributing Bibles "silently undermine the opposition to missions" of geographically stable preachers such as Daniel Parker, as well as spread literacy and Christian principles (including temperance and opposition to slavery) among the dispersed rural population. Peck moved to Rock Springs, Illinois in 1822 to farm, and arranged a circuit to visit the various societies which he continued to establish, as well as isolated farms. On one trip, Peck visited Daniel Boone, then nearly 80, and later wrote a book about the frontiersman's life.
