In the report that Maconochie sent back to Britain about penal colony in Tasmania What two key points were Tasmania?

1. Separation and Classification of Prisoners: Maconochie advocated for the separation of prisoners to prevent contamination and corruption among different classes of offenders. He introduced a system of classifying prisoners based on their conduct and progress, allowing them to progress through different stages of improvement and rehabilitation. This classification system later became known as the "mark system."

2. Rehabilitation Through Labor and Education: Maconochie believed that rehabilitation could be achieved through productive labor and education. He introduced a system where prisoners earned "marks" for their work, which could later be exchanged for improved conditions, privileges, and even early release. He also established schools and libraries within the prison to promote prisoners' moral and intellectual development.
