STATISTIK DER ZUM RESSORT DES KOENIGLICH PREUSSISCHEN MINISTERIUMS DES INNEREN GEHORENDEN STRAFANSTALTEN UND GEFAENGNISSE UND DER KORIGENDEN FUR DAS RECHNUNGSJAHRE, 1908; RAWITSCH, DRUEKEREI DER STRAFANSTALTSVERWALTUNG, 1909.

The article reports that the separate system (Einzelhaft) in the Prussian law means life in a cell day and night, sleeping or working, although in exercise and church attendance isolation is not absolute. A report shows that 4,998 cells were provided for 11,200 prisoners in the prisons for serious crimes, or 44.6 per cent; in the prisons for less serious offenses there were 7,804 cells for 9,314 prisoners, or 83.8 per cent. Since 1869 the number of cells have been increased from 3247 to 12,802. The older congregate prisons are preferred for recidivists; the cells are reserved as far as practicable for the younger and more hopeful; the theory being that the corrupting association of convicts should not be inflicted on those who give some promise of amendment.
