The establishment of the park has been a great blessing to all classes, but especially to the poor. It places within reach of the latter a great pleasure ground, where they may come and enjoy their holidays, and obtain the fresh air and bodily and mental enjoyment of which they are deprived in their quarters of the city. In mild weather they come here in throngs, with their families, and on Sundays the park is crowded with thousands who formerly passed the day in drunkenness or vice. The Commissioners have no trouble in enforcing their rules. All classes are proud of the park, and all observe the strictest decorum here. No crime or act of lawlessness has ever been committed within the limits of the Central Park since it was thrown open to the public. The popularity of the place is attested by the annual number of visitors. During the year 1870, 3,494,877 pedestrians, 75,511 equestrians, 1,616,935 vehicles, and 234 velocipedes, passed within the park gates. The total number of persons that entered the park during that year, including drivers and the occupants of carriages, was 8,421,427. XXI. THE DETECTIVES. I. THE REGULAR FORCE. The Detective Corps of New York consists of twenty-five men, under the command of a Captain, or Chief. Though they really constitute a part of the Municipal Police Force, and are subject to the control of the Commissioners and higher officers of that body, the detectives have a practically distinct organization. The members of this corps are men of experience, intelligence, and energy. These qualities are indispensable to success in their profession. It requires an unusual amount of intelligence to make a good Detective. The man must be honest, determined, brave, and complete master over every feeling of his nature. He must also be capable of great endurance, of great fertility of resource, and possessed of no little ingenuity. He has to adopt all kinds of disguises, incur great personal risks, and is often subjected to temptations which only an honest man can resist. It is said that the Detective's familiarity with crime is in itself a great temptation, and often leads him from the path of right. However this may be, it is certain that a member of the New York force committing an act savoring of dishonesty is punished by immediate expulsion from his post.
