In the center of the building is a rotunda 80 feet in width and about 70 feet in height, surmounted by a lantern. From this center six one-story corridors, or blocks, radiate like the spokes of a wheel. These vary somewhat in length, but average about 330 feet, and there is an average of about 70 cells in each. The floor space of each cell is 8×18 feet and the ceiling height is 13 feet, surmounted by a skylight. Of these corridors, A, B, C, and D are occupied by white prisoners, and two of the corridors, E and F, by colored. The number of prisoners at this date, February 1st, 1912, is 715, about ninety less than at this time last year. About 60 per cent. are white and 40 per cent. colored. All the prisoners are men. All women convicts are sent to the Moyamensing Prison. The total number of cells is 440, and usually each cell is occupied by two prisoners. Every cell is provided with a wash basin with running water, a closet, two iron bedsteads, a table and one or two stools. Each bedstead is provided with a mattress stuffed with 25 pounds of hand-picked corn husks and a 7-pound pillow of the same material. Beside a pair of sheets and pillow cases each prisoner has two 4-pound blankets of excellent quality. When a prisoner enters he undergoes a careful examination and a very complete record is made of all his personal characteristics. He then goes to the bathing room. An entirely new suit of clothing is given him, and the clothing with which he entered the prison is tied up in a sack, to which his name is attached by a tag. The sack is then placed in a room provided for that purpose, where it remains until his discharge from the jail. Wednesday and Thursday are bathing days, and each prisoner is required to take a bath at least once a week unless the physician certifies that the condition of the prisoner’s health would render bathing inexpedient. A change of bedding and underclothing is supplied to each prisoner on every Saturday. [Illustration: OFFICE OF ADMINISTRATION, PHILADELPHIA COUNTY PRISON FOR CONVICTS, AT HOLMESBURG]
