_Fifthly._ Here I can only glance at a matter to which I alluded on a former occasion. Our Eighteenth Report sets forth at length disparaging pictures by Mr. Dickens of the Pennsylvania System, while it makes no mention of opinions by Captain Hamilton (the accomplished author of "Cyril Thornton"), Miss Martineau, Dr. Reed, Dr. Matheson, Dr. F.A. Cox, Dr. Hoby, Captain Marryat, Mr. Buckingham, and Mr. Abdy, all of whom have expressed themselves with more or less distinctness in favor of that system. Nor does it make any allusion to authoritative opinions by different commissioners from foreign governments: as Crawford, from England, in 1834; Demetz and Blouet, from France, in 1837; Pringle, from England, in 1838; Julius, from Prussia, in 1836; and Neilson and Mondelet, from the Canadian government, in 1836,--all of whom reported emphatically in favor of the Pennsylvania System. Surely it was not candid and just to neglect all that these travellers and commissioners had reported, while bringing forward the imaginings of Mr. Dickens, and unearthing dateless letters of Roscoe and Lafayette, to employ them in a cause for which they were never written. _Sixthly._ Our Eighteenth Report is open to another objection, either of gross ignorance or most uncandid withholding of information. It employs these words, which appear remarkable when we consider the actual facts: "_What will be done in other countries is evidently_ _suspended, in a great degree_, on the results of more experience in regard to the effects of the system." Nothing more is said of what had been done in other countries, and the reader is left to infer that _nothing_ had been done. This was in May, 1843. Now what, _at that time_, had been done in other countries? In England the inspectors of public prisons had made two or more able and extensive reports in favor of the Separate System, where the principles on which it is founded are developed with fulness and clearness. Parliament had passed a law authorizing the creation of a model prison on this system at Pentonville. This had been built, and also other prisons on the same system in different parts of the kingdom. * * * * * Mr. DWIGHT. Will the gentleman please to state the difference between the prisons at Philadelphia and Pentonville? * * * * * Mr. SUMNER. With great pleasure, so far as any exists. The two are founded on the same principle of _separation_, though that of Pentonville is probably administered with less austerity than that of Philadelphia. They may differ in degree, but not in kind. I return to a review of what had been done in 1843, when I was interrupted.
