We believe that all reflecting men must be convinced that the _reformation_ of criminals, besides being a question of _expediency_, in which the community has a deep stake on the score of self-protection, is one, the promotion of which, so far as is in our power, is of the highest Christian obligation, in reference to both the temporal and eternal good of those who, having by their criminal conduct, forfeited the liberty enjoyed by the common mass of their fellow men, have, for the security of society, been committed to prison. In most Christian countries _reformation_, on the ground of _expediency_ at least, and we trust, under some sense of Christian duty, is now acknowledged to be properly _one_ of the elements of their penal systems; and, consequently, some provisions, either theoretical or practical, are adopted for the promotion of this object. It is much to be regretted, however, that most of the existing prison systems are such as greatly to interfere with, and many of them almost wholly to defeat the accomplishment of this vitally important purpose. This state of things exists to a great extent, not only in Europe, but throughout most of the Commonwealths of the United States. The systems are generally “_congregate_,” either with little, if any, restraint from free social intercourse between the inmates, whatever may be their different degrees of depravity, or with the imposition of silence while together, and separation at night and at their meals only. The former of these, in our judgment, wholly excludes reformatory influences, unless it be through the immediate operation of Divine grace and mercy, which, we freely admit, can overrule obstacles however great; but this fact will not excuse us from doing our best to facilitate this operation. At the same time, also, that it excludes reformation, its attendant circumstances rapidly school the young offender in the ways of depravity and crime, and harden the more practiced in wickedness, and prepare them for the commission of still darker deeds than any they had previously been guilty of. Whilst the latter system, where _silence_ is imposed, though certainly a step in advance of the former, as it cannot so extensively _propagate_ criminality, yet from the fact that the prisoners cannot be approached separately, and that this system of silence and non-intercourse amongst them, under the strong temptation to the indulgence of their social propensities when placed in the presence of each other, is only maintained by harsh and severe discipline; reformatory agencies can hardly be brought to bear upon them, and efforts in this direction, very rarely, indeed, produce the desired effect.
