"Prisoners Their Own Warders" by John Frederick Adolphus McNair is a history book that tells about the convict prison in Singapore from 1825 to 1873, and other places like Bencoolen, Penang, and Malacca. The book talks about how the prisons were run, how the prisoners were treated, and what the Indian prisoners did. It also looks at things like punishment, work, and trying to help prisoners become better people. The person who wrote the book wants to share the history of the prison system in Singapore because it can teach us things about how we deal with prisoners today, talking about where the convicts came from and the ways the prison leaders sorted and treated them, offering a base for going into details about the convicts building things, how the prison changed over time, and what it all means for using convicts to do work in colonial times.
