By the construction of an additional cell house in the space indicated by the dotted lines on the ground plan, and by the construction of an additional kitchen and mess hall between the present mess hall and the power house, the population of the prison may be doubled. The present prison is designed to accommodate 800 prisoners on a basis of five men to the large cells. By putting six men in the cells, however, the present population may be increased to something over 900. By constructing an additional mess hall and kitchen, racial segregation may be more completely effected. [Illustration: CELL BLOCKS--FLOOR PLAN] The present capacity of the hospital is 32 patients, but this capacity may be increased by extending the surgical and medical wards. At the rear of the prison a cotton mill and a shirt factory are being constructed to consume the labor of the present prison population. ECONOMY [Illustration: LAUNDRY, BATH, AND DETENTION BUILDING--FLOOR PLANS] The dominant consideration in the construction of the present prison has been the question of the maximum possible economy in first cost consistent with permanency and the security and welfare of the prisoners. All buildings are practically fireproof, but are no larger than are absolutely essential, and as far as possible all non-essential features have been eliminated. All essential utilities, such as a complete telephone system, alarm signal system, steam heat, an adequate lighting system for both the interior and the exterior of the prison, hot and cold water, etc., have been provided. OUTSIDE CELLS Economy in first cost was the guiding consideration in the construction of the cell houses, although a monolithic concrete structure with brick veneered exterior walls is by no means a cheap construction. But it is a permanent and safe construction. Economy in the construction of the cell house was secured through its compactness. The outside type of cell house can be made practically secure for all classes of prisoners when surrounded by an outside wall of adequate height, with its top guarded by high tension charged wires, provided the windows to the cell houses are barred with steel-proof window guards and the prisoners are reasonably well guarded. The relative hygienic and physiologic advantages of the outside and inside cell construction I will not discuss here except to say that we considered the outside cell construction manifestly superior in both of these respects. While we consider these features very important in a permanent prison, the question of economy in initial cost was also important in that the outside cell type of prison is a considerably narrower prison for the same cell capacity, and, furthermore, since continuous mechanical ventilation is not essential with the outside cell type, it can be more densely occupied, which further promotes economy in construction.
