In a few minutes I am ushered into the presence of the chief detective officer of the chief city of England. He sits in a room secluded from the main rooms, and as I pass through a number of these chambers a squad of men, who are sitting on chairs and lounges, look up at me quietly for a second, and, not recognizing any one whom they "want," drop their eyes immediately. The room in which Inspector Bailey sits is not a large one, and there is no superfluity of furniture, but the walls are covered with placards offering rewards for the apprehension and conviction of criminals, murderers, forgers, and other runaways from justice. Some of these are so curious that I must give a few of them: RING STOLEN--£1 REWARD. A reward of £1 will be paid for information that shall lead to the discovery of a gold ring, the setting in which was originally arranged for a round stone, with about five small teeth or holders to fix the same; the original stone having been lost it was replaced by an oval or pear-shaped rose diamond, which was loose in the setting. The said ring was stolen from a warehouse in the city, on the 14th inst.; and it is requested that any person hereafter offering it, for pledge or sale, may be detained until the police are informed. Information to Inspector Bailey, City of London Police, Detective Office, 26 Old Jewry: or to the officers on duty at any of the city or metropolitan stations. £1 10s. REWARD. TO CAB-DRIVERS, ATTENDANTS, AND OTHERS. INFORMATION WANTED. On Saturday, the 17th of April, 1869, about 4.45 in the afternoon, a four-wheeled cab, took up at Messrs.

He told the driver to take him to Finsbury square and he would tell him the number afterwards. £1 10s. reward will be paid on the required information (as to his destination) being given to Inspector Bailey, City of London Police, Detective Department, Old Jewry, E.C.
