The author examines conditions and practices inside American prisons around the turn of the twentieth century, surveying punishment types (including corporal and capital punishment), life sentences, dungeons, lock-step and chain gangs, and the daily work and treatment of inmates. Chapters address literary and religious privileges, tobacco and labor regimes, and proposals for reform, interspersed with a history of a state penitentiary and numerous letters and testimonies from prisoners and officials. The tone urges compassion and moral outreach, arguing that kindness, religious instruction, and access to literature can aid rehabilitation.
