Prison Reform: (Here are recorded a few facts about N. J. procedure, selected because of their connection with the administration of law for Newark. Complete review of state conditions and progress will be found in the Report of the Prison Inquiry Commission, published 1917.)
Indeterminate Sentence: Or sentence to imprisonment without a fixed time for its termination. Adopted by act of N. J. Legislature April 21, 1911. Is in accordance with the principle that imprisonment is primarily for reformation and that offenders should be released as soon as they have shown themselves again ready to be fit members of society. Provides for a maximum and minimum term, the maximum varying with nature of offense and the minimum not less than a year and not more than two-thirds of the maximum.
Prior to 1911 this practice had applied only to the State Reformatory.
Prison Labor: Law abolishing private contract system of labor directing that work of convicts should be employed in manufacture of goods for state-use was passed by N. J. Legislature, June 7, 1911. Prison Labor Commission created March 28, 1912, to direct development of "state-use" system and control its operation, but without sufficient authority to assure its success. Act passed, April 4, 1913, provided that unfilled contracts might be continued until state-use industries had been established. In view of the practical failure to introduce "state-use" system within the prisons, outside employment of prisoners was authorized by act of April 11, 1910, and subsequent amendments. Since 1913, 4 road camps have been opened for employment of convicts on state roads and have proved a relative success. Farming has also proved profitable. This system not only aims to prevent waste of state resources but to provide industrial training for inmates of correctional institutions of the state.
Employment of county prisoners and payment of earnings to their families was provided for by N. J. law passed 1915. Wardens of jails are instructed to give preference to men serving terms for nonsupport. At Essex Co. jail in Newark, $3,000 or $4,000 have thus been contributed to prisoners' families otherwise left destitute. Benefits will increase as practice is further systematized.
