they must not engage in conversation with any person on any part of their post, except in regard to matters concerning the immediate discharge of their duties." The uniform of the force is a frock coat and pants of dark blue navy cloth, and a glazed cap. In the summer the dress is a sack and pants of dark blue navy flannel. The officers are distinguished by appropriate badges. Each member of the force is provided with a shield of a peculiar pattern, on which is his number. This is his badge of office, and he is obliged to show it when required. The men are armed with batons or short clubs of hard wood, and revolvers. The latter they are forbidden to use except in grave emergencies. The general misdemeanors of which the police are bound to take notice, are: Attempts to pick a pocket, especially where the thief is a known pickpocket; cruel usage of animals in public places; interfering with the telegraph wires; selling or carrying a slingshot; aiding in any way in a prize fight, dog fight, or cock fight; destroying fences, trees, or lamps, or defacing property; aiding in theatrical entertainments on Sunday; disorderly conduct; participating in or inciting to riots; assaults; drunkenness on the streets; gambling; discharging fire-arms on the streets; and other stated offences. The officer must be careful to arrest the true offender, and not to interfere with any innocent person, and is forbidden to use violence unless the resistance of his prisoner is such as to render violence absolutely necessary, and even then he is held responsible for the particular degree of force exerted. If he is himself unable to make the arrest, or if he has good reason to fear an attempt at a rescue of the prisoner, it is his duty to call upon the bystanders for assistance; and any person who refuses him when so called on, is guilty of a misdemeanor, for which he may be arrested and punished. Promotions are made in the force as follows: Inspectors are chosen from the Captains, Captains from Sergeants, Sergeants from Roundsmen, and Roundsmen from the most efficient Patrolmen. The duties of a policeman are hard, and the salaries are moderate in every grade. The hours for duty of the Patrolmen are divided in the following manner: from six to eight o'clock in the morning; from eight o'clock in the morning to one in the afternoon; from one in the afternoon to six; from six to twelve midnight; from twelve midnight to six in the morning. These "tours" of duty are so distributed that no one man shall be called on duty at the same hour on two successive days. One-third of the entire force, about 700 in all, is on duty in the daytime, and two-thirds, about 1400 men, at night. Sickness and casualties bring down this estimate somewhat, but the men are such fine physical specimens that sick leaves are now comparatively rare.
