The park is controlled by the Commissioners of the Department of Public Parks. The principal executive officer is the President. The discipline prescribed for the employes is very rigid. A force of special policemen, who may be recognized by their gray uniforms, has been placed on duty in the park, with the same powers and duties as the Metropolitan Police. One of these is always on duty at each gateway, to direct visitors and furnish information, as well as to prevent vehicles from entering the grounds at too rapid a rate. Others of the force are scattered through the grounds at such convenient distances that one of them is always within call. None of the employes are allowed to ask or to receive pay for their services. Their wages are liberal. When an article is found by any of the employes of the park, it is his duty to carry it to the property clerk at the Arsenal, where it can be identified and recovered by the rightful owner. Improper conduct of all kinds is forbidden, and promptly checked. Visitors are requested not to walk on the grass, except in those places where the word "Common" is posted; not to pick flowers, leaves, or shrubs, or in any way deface the foliage; not to throw stones or other missiles, not to scratch or deface the masonry or carving; and not to harm or feed the birds. No one is allowed to offer anything for sale within the limits of the enclosure, without a special licence from the Commissioners. There are several hotels, or restaurants, in the grounds. These are conducted in first-class style by persons of responsibility and character. Private closets for men, which may be distinguished by the sign, "For Gentlemen only," are located at convenient points throughout the park, and cottages for ladies and children are as numerous. These latter are each in charge of a female attendant, whose duty it is to wait upon visitors, and to care for them, in case of sudden illness, until medical aid can be procured.
