The Governor for Manchester Prison (Colonel Isaacson), one of the most experienced and humane Governors in the Service, generalizes the result of moderate corporal punishment, humanely administered, as tending both to the moral improvement of the prisoner himself, and to the protection of the Staff. He says that "in every large Prison there is always a small "fraction of the population imbued with brutality, to whom "dietary punishment is absolutely useless. For these, when "they resort to personal violence on an officer, I can see no "alternative but the birch rod, or the cat."
