In this department of the prison the separate system is practised as far as can be done consistent with the plans of employment, and, with regard to the effect of the system, even with the limited advantage which it has in this place, favorable reports are made. One instance is mentioned by a visitor, who is most faithful to the duties he assumes and whose regular labors are almost entirely limited to convicts, and to those of a particular gallery, so that he may not by diversity of labors, or a multitude of objects, lessen the good effects of his visits or diminish the means of a close intimacy with the minds of those whose good he seeks. He has within a short time received letters from two soldiers in the Army of the Potomac, both of whom had been under his moral dealings in the County Prison at one time, and both were members of the ——th regiment, both returned thanks for the valuable instructions and kindness of the visitor, both professed to have derived the most important benefits from his care, yet neither of them knew that they had occupied adjoining cells in the County Prison, and neither of them was acquainted with the fact that the other was addressing their common benefactor. Instances of this kind, if not frequent, do at least occur sufficiently often to strengthen the hopes of the Society that the labors which its visitors perform in the name of benevolence and under the direction of the Association, are fruitful, in individual and social benefit. Fruitful in that good which was contemplated in the formation of the Society.
