The establishments within the boundaries of the Metropolitan Police area that survived the reorganization of 1829 were[189]-- i. The Bow Street Horse-Patrol, under the control of the Chief Magistrate at Bow Street. ii. The police constables under the separate control of the Magistrates of the Police Offices, to which they respectively belonged, being the following offices--Bow Street, Hatton Garden, Union Hall, Worship Street, Lambeth Street, Queen Square, Marlborough Street, High Street Marylebone, and the Town Hall Southwark. iii. The River Police, under the control of the Magistrates of the Thames Police Office. iv. The City of London Police, under the control of the Municipal authorities. Each of these independent establishments carried out its police functions according to its own peculiar ideas and local traditions. One and all were jealous of their powerful neighbour at Scotland Yard; and when they dared to do so, were not ashamed to countenance the petty and spiteful tactics that their subordinate officers lost no opportunity of indulging in. It will be remembered that a short supplementary Act[190] had contemplated the transference of the powers possessed by the Chief Magistrate at Bow Street over the Horse Patrol, to the Metropolitan Police Commissioners. This intention was not given effect to at the time, the Patrol being left under the command of its old chief, Mr Day; and the Act was repealed in 1833.[191] It was not until October 1836, or more than seven years after the passing of Peel's measure, that the Horse Patrol became an integral part of the Metropolitan Consolidated Police, an amalgamation which, besides increasing the actual efficiency of both forces, effected an annual saving of more than a thousand pounds.[192] The horse-patrolmen became mounted constables, being attached as such to the exterior divisions, where the beats were long; and this arrangement has been continued to the present day.
