X. _The character and position of the moral instructor should be such as to command the respect and confidence of the officers and inspectors._--There is no such thing as hood-winking prisoners on such a subject as this. They soon discover how much respect the executive authorities feel for the man who is appointed to such an office, and it is vain to suppose their estimation of him by those within the cells will be any higher. The moral thermometer on the outside and the inside of the partition wall, will indicate a similar temperature on this, and on most other subjects. There are prison chaplains and moral instructors in the world, whose characters and opinions challenge the regard and respect not only of prison officers and visitors, but of the public at large; and such have uniformly exerted a most sensible and happy influence on the wretched congregations committed to their charge. If the moral instructors in our State and County prisons are of this stamp, we may well congratulate ourselves that so important a post is adequately filled. If they are not possessed, in some good degree, of the qualities which have been enumerated, the sooner they are removed the better shall we regard it for the prison and for the public, for we are clear that an incompetent incumbent of such an office is an instrument of more evil than good. ART. II.--REPORT OF THE DISCIPLINE AND MANAGEMENT OF THE CONVICT PRISONS AND DISPOSAL OF CONVICTS, 1851-2, with notes on the Construction of Prisons, Treatment and Disposal of Juvenile Offenders, &c. By Lieutenant Colonel Jebb, Surveyor General of prisons of England, &c., pp. 218, with numerous plates. This document is dated in June last, and came to hand since our January number was issued. In a cursory reading of it, we have noted several points of general interest, and without attempting a classification of the topics, we will imagine our readers to be looking over our shoulder as we rapidly turn the leaves, making now and then a brief comment or two. In the ten prisons for separate confinement in England proper, there is room for 2,459 convicts, and 2,193 were in prison, leaving unoccupied accommodations for 266. In the three prisons for labor on the public works there were 1,931 confined, and only 17 more could have been received. In the hulks, there were 1,780 and only two vacancies; and in the Juvenile Prison at Parkhurst, there were 577 tenants and 29 vacancies. The total convict population of the year was 9,033, and there were 355 more on hand December 31, 1851, than at the same date in the previous year. Of the whole number, 13 were removed to Lunatic Asylums during the year, 147 were pardoned, (of whom 76 were on medical grounds,) and 111 died. In the report of the Millbank prison, we have an incidental testimony from the chaplain to the moral advantages of separation, which we think valuable.
