" Parlours.—A certain number of cell-parlours should be made, for the use of prisoners not authorized to meet their relations or friends in their own cells.
"Domestic Service—Administration—Lodying of persons employed in Prisons.—Whatever plan may be adopted, inde pendent of the localities above mentioned, each prison on the cellular system should contain a bath-room, with a number of separate baths in proportion to the number of inmates ; a kitchen, with its accessories; a baking-house ; and a wash house : a certain number of magazines for provisions, fuel, clothes, general stores, and manufactured goods, according to the destination of the prison ; a clerk's office ; and a meeting room for the committee of surveillance ; lodgings for the director or chief officer, the guards, or watchers ; and, in penal prisons; for the sub-director, the superintendent of works, the almoner, the doctor or his assistant, and of such other persons as may be placed in each prison by the admi nistration."—Builder October 9, 1847.
In the new prison which has been built at Holloway, for the Corporation of London, it has been endeavoured to carry out these ideas. It is constructed upon the radiating prin ciple, having four wings diverging from One centre, with two other wings in front of the former : one of these wings is for juvenile offenders, with school-rooms attached ; the other for females, with work-rooms and laundry ; the other four radiating wings constitute the male adult prison. These have large work-rooms attached, and an apparatus for lifting water. The wings are twelve cells in length, or about 100 feet, and 3 stories high. The corridors are 16 feet wide, and are open up to the arched ceiling, with galleries leading to the upper cells. The cells are 13 feet by 7 feet, fitted up with water-closets, wash-hand basin, cupboard, table, stool, &c : these are warmed by means of hot-water pipes laid under the corridor-floor, the air passing over them and through the flues provided in the thickness of the wall, and entering the cell over the door. The ventilation is to be effected by means of a shaft, 146 feet high, of large dimen sions. Inside this shaft is a tube of boiler-plate the whole height of the shaft, 5 feet diameter at bottom and 3 feet at top. In addition to a furnace at the bottom of the tube, the
smoke from the various chimneys, together with the spare heat from the kitchen boilers, is conveyed into it, and will necessarily raise the temperature of the column of air in the shaft, and make it pass off with great rapidity. The theory is, that as no air can enter the shaft without previously pass ing through the cell, a constant supply of fresh air will thereby be conveyed to the prisoners.
The chapel is a spacious room 70 feet by 40, and 48 feet to the ridge of the roof, with two deep I eeesses for the females and juveniles, and will contain sittings fiir 3s0 prisoners. Provision is made fir having a constant supply of fresh air passing through the chapel to the ventilating shaft. The arrangements for taking the prisoners from the various cells to the chapel, have been well considered. The females and juveniles enter by separate doors near the altar, while the male prisoners enter by four dillbrent passages at the opposite end. The kitchen is of ample dimensions, and being close to the base of the ventilating shaft, the steam and smell from the victuals will lie carried off 'l'he well-house is to be fitted with One Of Mr. disc pumps, and to be worked like a capstan, in a building 30 feet diameter. The shaft is 217 feet deep, bore 102 feet, making a total depth of 319 feet. The depth to the water is 153 feet. The tanks, to contain I-1,000 gallons, are placed over the front towers at a great elevation, from which the cells and other places are supplied : the whole depth of bore is in chalk.
The whole extent of frontage next the Camden-road is of Kentish rag, with Caen-stone dressings, 'l'he style is cas tellated Gothic. The sides of the chapel building, and the back wings, are of brick ; the windows to the cells have Parkspriug-stone sills, with splayed brick reveals. The whole of the parapets are coped with Caen-st(me. The roofs are flat, covered with asphalte, upon plain tiles :01d iron rafters. As the extracting flues for ventilation imme diately under the roofeovering, two thicknesses of plain tiles have been put ti inches apart, to prevent the atmosphere acting in any way against the free current of air passing through them.
