The Committee on the County Prison have attended faithfully to their duty as visitors during the year, but the reports from them are not so minute as those from the Committee on the Penitentiary, and, consequently, we are unable to analyze them so as to set forth the particulars of their services. One of the members so thoroughly devotes his time to the duty, as to visit the prison more than 500 times during the year, generally twice a day for more than 250 days. The other members report having among them paid 419 visits in the course of the year. Under the care of the present judicious and efficient Board of Inspectors, the prison has been satisfactorily conducted; but the population is so unsettled (being largely composed of vagrants, the untried, and those committed for petty offences), that it cannot be considered to fairly illustrate the “Separate System,” and therefore we think it proper to make more especial and extended reference to the Penitentiary than to it. The Prison “Association of Women Friends” (which is recognized by us as an auxiliary in the good work), have continued to be diligent visitors to the females confined in both prisons, and have entered on the service under a full sense of its serious importance, and with desires that their labors might be promotive of the temporal and eternal good of the visited. In the course of the year they paid 987 visits to the prisoners in the two institutions. In addition to the moral and religious instruction communicated to those confined in each of the institutions, through the medium of our visitors and those of the association just referred to, the Eastern Penitentiary has, as one of its regular officers, a “Moral Instructor,” whose time is devoted to visiting the prisoners individually in their cells, and there instructing them in those things which most nearly concern their temporal and eternal interests. The present incumbent of the office is John Ruth, a worthy minister of the Methodist persuasion, who appears to be well fitted for the discharge of the duties of his station. Ministers of different denominations also frequently visit the Penitentiary, both for the purpose of having religious opportunities with individual prisoners, and for the more general and public discharge of the duties of their calling. In the County Prison, although there is no regular officer employed for the purpose as in the Penitentiary, yet the institution is pretty well supplied with volunteer religious instructors from different sources, and, on the first day of the week, the prison agent generally procures the attendance there of one or more ministers.
