We have made these suggestions with much freedom, and we hope without offence. We have hearty, intelligent co-adjutors in Jersey, who are aiming with us to establish the convict-discipline of the country on a truly humane, efficient, philosophical and Christian basis. To this end, we maintain that every prison or place of confinement for persons charged with or convicted of crime, should furnish a suitable apartment for each individual, separate from every other individual suspected or convicted of crime. We have often cited the State prison at Trenton as one of this class, and have uniformly espoused the views of the Inspectors and principal officers, at times when they were opposed by crotchety speculators within or without the prison; and we shall be greatly disappointed, if means are not promptly used to conform the discipline to the provisions of law. ART. VII.--AN EXTRAORDINARY DOCUMENT. We have before us a stitched pamphlet, entitled "Report on the Subject of Prisons, by Rev. Alexander L. Hamilton, State Commissioner, to Hon. Austin King, Governor of Missouri--Referred to the Committee on the Penitentiary, and three thousand copies ordered to be printed, January 5, 1853," pp. 24. The author of this report is, we doubt not, a very worthy and intelligent gentleman, or he would not have been appointed by the Executive of Missouri on so important an agency. That he has fulfilled his mission to the best of his ability, we may also admit; but that his report contains "such information as is necessary to present the subject of Prison Discipline fully to the consideration of the next general assembly of Missouri," we cannot believe. Indeed we do not hesitate to say that it is entirely deficient in every point that a report on such a subject, for such a purpose, should embrace. Statements are made, which have been disproved over and over again, until the repetition of them is loathsome to those who have been familiar with the subject. Principles are set forth as of present validity, which have been long ago abandoned even by those who once advocated them. The most ultra partisan opinions and doctrines are revived, with such an air of sincerity and confidence, as leads us to believe that the Rev. Commissioner never saw or heard of the oft-repeated refutation of them. He refers to those whose minds are steeped in prejudice, as the most reliable and responsible sources of information; and perhaps we cannot better describe the document, as a whole, than by saying that it is a synopsis of the reports of the Boston Prison Discipline Society and Mr. Gray's book, prepared and printed at the expense of the State of Missouri. We owe it to ourselves to cite a passage or two from the report, to serve as an indication of the qualities we have mentioned. As to its rhetoric and logic let the following suffice:
