The author gathers fragmentary personal recollections of the antislavery movement in the United States, recounting campaigns, speeches, trials, riots, rescues, and political struggles he witnessed or learned of, especially in Massachusetts, Connecticut, and Central New York. He profiles activists and opponents, examines religious and social tensions, and treats episodes such as school and church controversies, legal battles, mob violence, the Underground Railroad, and the Fugitive Slave Law. The sketches are anecdotal and candid, aimed at illustrating how slavery influenced clergy, congregations, and public life rather than providing a comprehensive history.
