The lower cells can be used for prisoners who are not likely to attempt to escape, and the upper ones for those who are recognized as dangerous criminals who are likely to escape. There will be a distance of six feet from the top of one window to the bottom of the next above, and the windows will be so constructed as to give the least possible opportunity for a foothold. The height of the building will be so great as to make escape by means of ropes practically impossible. The outer walls will be illuminated at night and four night guards on the roof of the Criminal Court Building can keep the entire exterior of the jail in view. The short cell wings will be easily supervised from the central rotundas, and the jail elevator will permit of prompt re-enforcement of the guards on the several floors in case of necessity. The sixth floor will be devoted to the clinics and the hospital. There will be provision for medical, surgical, dental, psychologic, and psychiatric clinics with two wards, 32 by 90 feet, for 22 beds each, and a third wing containing 12 single rooms in order to permit of isolating contagious and infectious cases. EMPLOYMENT AND RECREATION The ninth floor (the fifth floor of the jail proper) will contain an auditorium to accommodate 600 men; four school-rooms, instead of the one school-room in the present Cook County Jail; and four small shops where prisoners who desire to work may be permitted to do so and to receive their earnings for themselves or their families; these shops to be organized on a plan similar to that of the occupational therapy shop in the Indiana State Prison at Michigan City. This floor will be 14 feet high instead of 10 feet, in order to give head room for the auditorium. The auditorium will be located in the middle of the building, in order to minimize the stair climbing of prisoners going to that floor. [Illustration: HOSPITAL AND CLINICS--FLOOR PLAN] A roof garden will give opportunity for outdoor exercise. It will contain four sections, each 32 by 90 feet, which will give opportunity for indoor baseball, handball, tennis, walking, and so forth. The rotunda in the central space will give opportunity for invalids to get the benefit of fresh air. The prisoners will be divided into sections for exercise on the roof, coming up in squads of 50 or more. The roof garden will be enclosed in a strong netting, to obviate danger of suicides or attempted escapes. The separation of each floor will simplify the problem of heating and ventilation, which will be as simple as that of any office building. The division of each floor into four distinct compartments will permit of classification in as many groups of 25 as may be desired. If there are six floors, there will be 27 possible groups.
