WHereas it hath pleased God in an extraordinary measure to afflict this His MAJESTIE's City of London with several dismal Accidents of Fire, and that all the Care and Watchfulness hitherto practised, and even his MAJESTIE's personal Appearance on the occasions of Danger, have not been sufficient to stir up and excite so great a Circumspection and Vigilance as is necessary; And whereas some Suspicions have arisen as if there were persons of such lewd and damnable Principles as out of more Malice to affect the Destruction of His MAJESTIE's said royal City by Fire, and others so depraved as to attempt the same thing in hopes of Plunder and private Gain, when by the Disorders which usually attend such Calamities they may with more freedom and impunity pillage and take away whatever they can get: His majesty therefore, being most deeply sensible and apprehensive of all Dangers of like nature which may happen to His said City, or the Suburbs thereof, or to the burrow of Southwark, hath thought fit to Order, and it is hereby Ordered accordingly, That not onely the Lord Mayor of London, but the Justices of the Peace in the respective places abovesaid, do take particular and effectual Care that a most diligent Watch and Ward be maintained in all places of the City and Suburbs, and the burrow of Southwark, according to Law: And that suitable to the laudable custom of the City care be taken, that in each respective Ward, and in the several Parishes of the places abovesaid, there be provided a necessary Store of Engines, Ladders, Buckets, and all other the Preparations which can be thought fit to prevent the dismal consequence of Fire when any accident shall happen.  
And farther, the said Lord Mayor and Justices of the Peace respectively are required to cause diligent Observation to be taken of all Vagrant and Suspicious persons walking at Unseasonable Hours, and to examine and search if they carry about them any Combustible matters: And in case such persons are not able to give a good account of themselves, they are forthwith to be conveyed before the next Justice of the Peace, to be proceeded against and severely punished according to the Law and the quality of their Offences.
