State prisons have been under construction at Bellefonte, Pennsylvania; Sing Sing, New York; Statesville, near Joliet, Illinois; and Montgomery, Alabama. Westchester County, New York, has built and Detroit, Michigan, has begun a prison for short term misdemeanants. New York City and the District of Columbia have partially completed reformatories for young men. New reformatories for women have been established in Arkansas, California, Connecticut, Iowa, Kansas, Maine, Minnesota, Missouri, Nebraska, New Jersey, Ohio, Pennsylvania, and Wisconsin. Most of them have adopted cottage plans similar to those of industrial schools for delinquent girls. All of them are in process of development. Most of them have erected from one to three new buildings and are making use of old farmhouses as temporary cottages. Comparatively few new county jails have been built. Probably the most notable one built in the past seven years is the Hamilton County Jail in Cincinnati, which is reported as a modern and model jail, located in the top of the Court House, like the jails in Philadelphia, Minneapolis, Oakland, California, and Raleigh, North Carolina. Plans for a new county jail system at Chicago for Cook County are being worked out by a local committee which has retained Dr. George W. Kirchwey, of New York, as expert adviser.
