_Prison Library._—The Library at the Penitentiary now contains about 2,900 volumes, of which about 680 are in the German and French languages. The selection has been made with a view to furnishing interesting and instructive reading, adapted to the various capacities and tastes of the prisoners; and it is satisfactory to be able to report that the books are extensively used. The number of volumes loaned during last year was about 20,000. When we remember that the average number in confinement during the year was not over 458, many of whom were very degraded and ignorant, and wholly unable to read when they entered, it becomes in our view, an interesting feature of our system of discipline, not only that the opportunity for mental exercise and enjoyment should be so freely presented, but that these poor creatures should feel the inclination to avail themselves of it so largely, whether it be for mere amusement or for instruction. There is also a smaller Library at the County Prison of a similar character. _Number in the Penitentiary in 1861._—The entire number of prisoners in the Penitentiary during the year 1861, was 646. The largest number at any one time was 485, and the smallest 431. The state of health amongst them was generally good, and the per centage of mortality exceedingly small, there having been only two deaths. _Prison Society’s Visitors and Visiting._—We now come to speak of what, under all considerations, is, we believe, the most important part of the action and services of the Society—that which is accomplished through the agency of the Visiting Committees. To give to those who have not been on the appointment a clear view of the manner and extent of the action in this direction, it may be best to mention the preliminary arrangements. At the Annual Meeting of the Society forty-four members are elected, who, with the officers ex-officio, form the “Acting Committee.” After the election, this Committee organizes and subdivides itself into two Visiting Committees, one of them allotted to the County Prison, and the other to the Eastern Penitentiary. These sub-Committees next organize and allot to each of the members a certain division, or portion of a block or corridor, containing only such a number of cells as will admit of his paying frequent visits to each of the inmates. The Committees hold meetings monthly, at which time each member is expected to make a report of the number of visits he has paid to the prison, and the number of interviews he has had with the prisoners, particularly designating such as took place _inside of the prisoners cell_, which interviews are considered to be much more likely to be serviceable than those at the cell door. When any thing of especial interest occurs, it is expected also to be added to the report. The reports, at least as regards the Penitentiary Committee, are required by the rules to be in writing, and 182 of such reports have been made by them during the
