In 1962, Hopper, in "The Journal of Criminal Law, Criminology, and Police Science", said that the Mississippi State Penitentiary had the most liberal visitation program in the United States. Rules of visitation and leave, adopted in 1944, allowed inmates to make home visits for reasons other than emergency. According to a 1956 survey, it was the only correctional facility in the country to do so. Inmates were allowed to be visited every Sunday for two hours by their wives. In 1962, each Parchman camp, with the exception of the maximum-security camps, housed a five to ten-room structure called a red house; each house is near the main gate of the main camp building. In the house, the inmate and his wife may engage in sexual intercourse. Children are encouraged by the prison authorities to visit; as of 1962 one camp houses a play area for children. The Parchman conjugal visit program is designed so that all members of the family may interact with a particular prisoner. In 1962, the prison officials said that the conjugal visits were an important factor in preserving marriages of inmates and reducing prison homosexuality. During that year, most inmates reported favorable opinions about the conjugal program.
