However, the Act of 1865 was a great step forward. Prisons still remained under the control of the local Justices, but every prison authority was required to provide separate cells for all the different classes of prisoners. These cells were to be such as could be certified by an Inspector of Prisons that they satisfied all the requirements of the Rules. Elaborate provisions were introduced for regulating "Hard Labour," (a phrase carried on from early Acts of Parliament, framed before the days of scientific accuracy). It was divided into two classes: (1) the treadwheel, shot-drill, crank, capstan, stonebreaking, &c. (2) any other approved form of labour. All prisoners over sixteen were required to be kept to first class labour for at least three months, after which time they would qualify for the second class. Dietaries were to be framed by the Justices, and approved by the Secretary of State, and any Rule they might make was to be subject to the approval of the Secretary of State. If they failed to comply with the Act, the Secretary of State was able to stop the Treasury contribution towards expenses of the Prison. It was also authorised, for the first time, that a prison authority might make a grant in aid of prisoners on discharge. The Schedule to the Act comprises details of the Rules regulating the administration of the Act on matters of Prison treatment. The power of punishment was restricted to Justices and the Governor of the Prison, the latter having power to order an offender to be placed in close confinement for three days on bread and water; the former could order one month in a punishment cell, or, in the case of a convicted felon sentenced to hard labour, could order flogging. Regulations were also made for the use of irons or other forms of mechanical restraint. The important principle was enacted, which has since remained in force, _viz_:--that no prisoner may be employed in the discipline of the prison, or the service of any officer, or in the service or instruction of any other prisoner.
