Now, without denying that imprisonment of all sorts is an unnatural state for any man to be in, and therefore likely to bring to light whatever latent proclivities to physical or mental infirmity may exist; or that there may be a neglect of hygienic laws, and a disregard of those precautions, which professional skill or common prudence may suggest for the counteraction of morbid agencies;--we confidently affirm that the separation of a convict from his fellows, has no tendency in that direction to make it an objectionable feature of prison discipline. On the contrary, we believe its legitimate influence, when administered by humane and intelligent men, (and no prison should be governed by any other,) is highly favorable to moral and intellectual and physical improvement, and more likely to answer the ends of punishment, than any other system now known. But to return to the political nuisance. It is not only into these more imposing and expensive institutions (the patronage of which may be supposed to avail something in political struggles) that the baneful influence of party spirit intrudes itself. It was but lately that the project of a House of Refuge in a neighboring State, fell through between political parties. If we are not misinformed, one of the most useful and successful institutions for the reformation of juvenile offenders in our country, has been sadly embarrassed by the same cause, and another of like character, all completely furnished and ready for occupation, remains with closed doors till the appointing powers can settle some political squabble.
