I am always fearful of any punishment, beyond what the law publicly authorizes, being privately inflicted by any keeper or officer of a prison; for my experience most strongly proves that there are few men who are themselves sufficiently governed and regulated by Christian principle to be fit to have such power entrusted to their hands; and further, I observe that officers in prisons have generally so much to try and to provoke them that they themselves are apt to become hardened to the more tender feelings of humanity. They necessarily also see so much through the eyes of those under them, turnkeys and inferior officers, (too many of whom are little removed either in education or morals from the prisoners themselves,) that their judgments are not always just. The next point that struck us was, that in the cells generally the windows have that description of glass in them that even the sight of the sky is entirely precluded. I am aware that the motive is to prevent the possibility of seeing a fellow-prisoner; but I think a prison for separate confinement should be so constructed that the culprits may at least see the sky--indeed, I should prefer more than the sky--without the liability of seeing fellow-prisoners. My reason for this opinion is, that I consider it a very important object to preserve the health of mind and body in these poor creatures, and I am certain that separate confinement produces an unhealthy state both of mind and body. Therefore everything should be done to counteract this influence, which I am sure is baneful in its moral tendency; for I am satisfied that a sinful course of life increases the tendency to mental derangement, as well as to bodily disease; and I am as certain that an unhealthy state of mind and body has generally a demoralizing influence; and I consider light, air, and the power of seeing something beyond the mere monotonous walls of a cell highly important. I am aware that air is properly admitted, also light; still I do think they ought to see the sky, the changes in which make it a most pleasant object for those who are closely confined. When speaking of health of body and mind, I also mean health of soul, which is of the first importance, for I do not believe that a despairing or stupefied state is suitable for leading poor sinners to a Saviour's feet for pardon and salvation.
