Finally, we would commend this subject to the attention of all. In the language of Sir Michael Foster, a judge of eminence in the last century, "No rank or condition of life, no uprightness of heart, no prudence or circumspection of conduct, should teach any man to conclude that he may not one day be deeply interested in these researches." There are considerations of self-interest which may move those who do not incline to labor for others, unless with ultimate advantage to themselves. But all of true benevolence, and justly appreciating the duties of the State, will join in effort for the poor prisoner, deriving from his inferior condition new motives to action, that it may be true of the State, as of law, that the very least feels its care, as the greatest is not exempt from its power. In the progress of an enlightened Prison Discipline, it may be hoped that our penitentiaries will become in reality, if not in name, Houses of Reformation, and that convicts will be treated with scrupulous regard for their well-being, physical, moral, and intellectual, to the end, that, when they are allowed to mingle again with society, they may feel sympathy with virtue and detestation of vice, and, when wiser, may be better men. In the promotion of this cause, the city of Boston at this moment occupies a position of signal advantage. It has determined to erect a new county jail, and the plans are still under consideration. It is easy to perceive that the plan it adopts and the system of discipline it recognizes will become an example. No narrow prejudice and no unworthy economy should prevent the example from being such as becomes a city of the wealth, refinement, and humanity of Boston. It is a common boast, that her schools and various institutions of beneficence are the best in the world. The prison about to be erected should share this boast. _Let it be the best in the world._ Let it be the model prison, not only to our own country, but to other countries. The rule of separation, considered of such importance among the ripe convicts of the penitentiary, is of greater necessity still in a prison which will receive before trial both innocent and guilty. From the first moment he is touched by the hand of the law, the prisoner should be cut off from all association, by word or sight, with fellow-prisoners. The State, as his temporary guardian, mindful of his weakness, owes him this protection and this means of reformation.
