"The Act of 1737 with little modification controlled the policing of the City of London for little over a century. The Force remained the direct responsibility of the Mayor and Aldermen but later was placed under the supervision of two Marshals who were assisted by six Marshalmen. The duties of the Marshals, besides supervising the City Police Force, were to keep books of occurrences to be laid before the Court of Mayor and Aldermen at every meeting; attend at public processions on horseback and regulate them; cause the Constables of the City to be summoned according to precept or order of the Lord Mayor; hire as Constables decent men, giving preference to the Ward Constables as additional Constables when required; attend the Markets and preserve the peace at Bartholomew Fair; apprehend all rogues and pickpockets; patrol the streets to see that they were clear of vagrants, and many other duties readily accepted as normal Police duties today They were also required to give notice of any non-freemen exercising their trades within the city, and put in force all orders of the Court of Aldermen and Common Council for order of the City according to the Statute and Common Law, and suppress all affrays and riots. The Marshalmen were appointed to assist the Marshals in carrying out these duties, and to execute all warrants and summonses. They supervised both the Ward Constables and the Watchmen, and recorded daily in a book at the Mansion House the state of the City, in order that the Marshals might report to the Lord Mayor...."
