Mr. Kennedy is not a popular man in New York. To say that he has made mistakes in his present position, is but to say he is human. He has had a hard task before him, but he has succeeded in accomplishing it. He has given order, security, and a sense of security to the city, and it is not strange that in so doing he has made numerous enemies. He has often exceeded his power, and has committed acts that smack strongly of petty tyranny; but there can be no doubt of the fact that he has earnestly and faithfully labored for the cause of law and order. He makes the best chief of police this country has ever seen, and when he is gone, his place will be hard to fill. Mr. Kennedy has Scotch-Irish blood in his veins, which may be the reason of his success. He is small in size, and quiet and unobtrusive in his demeanor. He has executive ability of a high order, but inclines rather strongly to the side of arbitrary power, which trait has earned him, amongst the masses, the title of "King Kennedy." He has infused his energy into the force, and is entitled to the greater part, if not all of the credit for the success of the new system. THE FORCE. The police force on duty in the city, consists of one super intendent, four inspectors, thirty-four captains, one hundred and thirty-one sergeants, one thousand eight hundred and six patrolmen, sixty-nine doormen, and fifty special policemen, making a total of two thousand and ninety-five officers and men. The men are clothed in a neat uniform of dark blue cloth, with caps of hard polished leather. They are armed with clubs and revolvers, and are regularly drilled in military tactics. In case of a riot, this enables them to act together, and with greater efficiency against a mob. The most rigid discipline prevails, and the slightest error on the part of officers or men is reported at headquarters. There are thirty-three precincts, including the detective squad. The force is charged with the duty of guarding about three hundred day and four hundred night posts, about four hundred and twenty-five miles of streets in the patrol districts, and fourteen miles of piers. There are twenty-five station houses fitted up as lodging rooms for the men, and having room also for accommodating wandering or destitute persons, large numbers of whom thus receive temporary shelter. During the year ending October 31, 1865, (which may be taken as a fair specimen of the work of the force,) 68,873 arrests were made. Of these 48,754 were males, 20,119 females; 53,911 arrests were for offences against the person; 14,962; for offences against property.
