And of course, by having inmates grow their own food, and make their own clothes, for example, institutions become as self-sufficient as possible, which benefited the public. Farm colonies sprung up to grow the produce and animals that were needed to feed the nearby institutions. Here you have some able-bodied male inmates who have been moved out to these farms to live and work. The inscription again is telling: "The simple life for simple folk. Occupation was the sign of intelligence."
