This institution was established in 1887, and is located at St. Cloud. It is designed as an intermediate correctional school between the training school and the state prison, the object being to provide a place for young men and boys from sixteen to thirty years of age, never before convicted of crime, where they may, under as favorable circumstances as possible, by discipline and education best adapted to that end, form such habits and character as will prevent their continuing in crime, fit them for self-support, and accomplish their reformation. The law provides for an indeterminate sentence, allowing of parole when earned by continuous good conduct, and final release when reformation is strongly probable. Honest labor is required every day of each inmate. Almost every occupation and employment is carried on in a practical way, and each inmate is learning to fill some honest place and to do useful work. The workings of this reformatory have been very satisfactory, and have undoubtedly rescued many young people from a life of crime. THE MINNESOTA STATE PRISON. All prisons where criminals are sent to work out sentences for crimes committed are alike on general principles, and the Minnesota prison, situated at Stillwater, differs only in the fact that it combines in its administration all the modern discoveries of sociological research which tend to ameliorate the condition of the prisoner and fit him for the duties of good citizenship when discharged. The plant is extensive and thorough. The labor of the prisoners is now devoted to three industries: the manufacture of binding twine, high school scientific apparatus on state account, and the manufacture of boots and shoes. The discipline and management of the prison are the best. The most advanced principles of penology are in force. Sentences are reduced by good conduct, and everything is done to reform as well as punish the prisoner. A newspaper is published by the convicts, and a library of five thousand volumes is furnished for their mental improvement. Nothing known to modern social and penal science is omitted from the management. THE MINNESOTA HISTORICAL SOCIETY.
