Finally, to insure an adequate supply of ventilation in the summer, when there may be neither wind nor temperature difference, we have mounted disc fans in each ventilator, driven by ball-bearing shafting from a push-button-controlled motor. By this means the cell attendants, by pushing a button, will be enabled to flood the cell house with fresh air at any time the air becomes foul, and since the attendants will be on the inside of the prison, where the air will be most foul, they will probably make use of their opportunities. Apart from humanitarian considerations, which in a large measure should dominate the designer of a prison, there is also the economic question of securing the maximum mental and physical output from the prisoner while at work. In an industrial prison a man can do more and better work if he sleeps and rests sufficiently. If the cotton mills are to be operated double shift during summer months with a large portion of the population sleeping during hot summer days, it is doubly important that the prisoners be confined in well-ventilated and sanitary quarters. This fact we have borne in mind in the design of the cell houses at Kilby Prison. Prison Farms for Women _By_ HASTINGS H. HART, LL.D. [Illustration: PERSPECTIVE OF RECEPTION BUILDING, CONNECTICUT STATE FARM FOR WOMEN, NIANTIC, CONN.] Several States are developing prison farms for women on the cottage plan. We present herewith plans of two cottages recently constructed at the Connecticut State Farm for Women at Niantic and the New Jersey Reformatory for Women at Clinton. State Farm for Women at Niantic, Connecticut--Reception Building State reformatory institutions for women are rapidly being developed in the United States. The first two institutions of this class, the Indiana State Reformatory for Women at Indianapolis and the Massachusetts Reformatory for Women at Framingham, were prison structures, less rigid and formal than typical prisons for men, but still following prison models. In the meantime the cottage system for younger girls grew up, and it was soon found that delinquent girls could be safely kept in ordinary cottages without any surrounding wall and without prison construction. When the New York State Reformatory for Women was built at Bedford, cottages were erected instead of a large congregate building, and the gates of the institution stood open day and night. While occasionally escapes took place, the number was not large, and the fugitives were usually speedily recaptured. All the new institutions for delinquent women are on the cottage plan, and in most cases the cottages are of simple construction, without window gratings, strong bars, walls, or even fences. In some cottages an iron grill protects the lower sash; sometimes this grill is masked by window plants.
