Boards of trustees, managers, directors, or some other local governing body, exist in the following states but without exclusive control:—Alabama, California, Connecticut, Delaware, Georgia, Idaho, Indiana, Louisiana (administrators), Maine, Maryland, Massachusetts, Mississippi, Missouri, New Jersey, New Mexico, New York, Pennsylvania, South Carolina (regents), Texas and Virginia.[23] In the following states the hospitals have no local boards of any kind:—Arizona, Arkansas, Colorado, Florida, Illinois, Iowa, Kansas, Kentucky, Michigan, Minnesota, Montana, Nebraska, Nevada, New Hampshire, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Rhode Island, South Dakota, Tennessee, Utah, Vermont, Washington, West Virginia, Wisconsin and Wyoming.[24] As the state hospitals increased in number and importance, steps were taken to coordinate their activities and for various obvious reasons they were soon grouped together in departments. In the states having a sufficient number of hospitals to warrant such a procedure, separate specialized administrative units were established under lunacy commissions, etc. In less populous communities where there were only a few hospitals there soon developed a tendency to associate them with the charitable, correctional and, in some instances, penal institutions. Seventeen states, as has been shown, now have only one hospital for mental diseases, eight have two and ten only three institutions. This led either to placing the hospitals under boards of charities and corrections or to the organization of new departments known as boards of control. The hospitals for mental diseases are under the supervision of boards of charities and corrections in the following states:—Colorado, Connecticut, Indiana, Louisiana, Maine, Nebraska, North Carolina, South Carolina, South Dakota and Virginia.[24]
