I've had a good find today through that great online newspaper archives facility and thought I'd post it for possible interest or future browsers. 'JOJ' extracted a column's-worth of Oxon-related info from a parliamentary report of gaol inspectors for their issue dated 26 July 1862. Much detail therein on Oxford County Gaol and Oxford City Gaol. For the County Gaol, it says: "The labour performed by male prisoners consists of the treadmill, which is entirely unproductive; a capstan pump for raising water for prison use; and oakum picking. The females wash, iron, knit, and make and mend the prison clothing. There are 10 hard labour machines in the prison, but their use has been abandoned since 1858. The money actually received for the picking of oakum during the year has been 8l. 15s. The estimated net value of prisoners' earnings while employed for the county, making and mending shoes, has been 44l. 9s. 4d., but in this estimate no credit is taken for the value of the women's labour." And, for the Oxford City Gaol: "The male prisoners are employed on the treadmill, which is entirely unproductive, and in oakum picking; the females also pick oakum, and do the washing and ironing. The oakum picking has produced 6l. 13s. 3d. in the last year, and the prisoners' earnings for the county in making twelve suits of prison clothing are estimated at four guineas." 17 years later, the 'JOJ' issue dated 27 Dec 1879 gave details from the 1878-9 Commissioners of Prisons Report (including some info on staffing and costs for the Berks & Bucks County Prisons). An extract from the section on the Oxford Gaol stated: "During the year 23 males were placed in punishment cells, 171 were put upon dietary punishment, and 59 lost stage or privilege. The total number punished was 194, and 697 males and 116 females were not punished. The prison offences consisted of 63 cases of idleness and 157 breaches of regulations, all on the part of males. . . . the net profit on work done by prisoners was 62l. 8s. 5d., and the work done for the prison was valued at 376l. 10s. Industrial work was only commenced in August, 1878, no remunerative or industrial labour having ever been carried on before. Hard labour, first-class, consists of the treadmill (which accommodates 18 persons), crank machine, shot drill, and capstan pump." Special attention had been given to 'moral and secular instruction' of juveniles and "One prisoner was executed, and another received pardon on medical grounds". The statistics don't separate out child prisoners. Best wishes, Carole (Devon, UK)
