The second reason why delay was dangerous was because of the enormous increase of population in the manufacturing towns. Trade was brisk, money plentiful, and the rapid development of the railway system caused an increasing stream of workers to flow from the country into the industrial centres. The population of Birmingham, for instance, increased in this way from 90,000 in 1815 to 150,000 in 1832.

The last of the three reasons which contributed to make this particular moment especially opportune for insisting that the provincial towns should provide themselves with an improved and adequate police, was because Municipal reform was the question of the hour, and it was therefore extremely important that the new-fashioned Boroughs should neither perpetuate faulty tradition nor originate impracticable experiment.

The history of English Boroughs cannot here be discussed; it will be sufficient to remark that, early in English history, charters, giving powers of self-government, had been granted to many towns and by many successive sovereigns. The creation of Corporate Towns was esteemed one of the highest prerogatives of the Crown, but the powers so conferred were seldom employed to the best advantage; and the fact that failure was especially pronounced in the matter of peace-maintenance is sufficiently illustrated by the examples already given of borough police forces, as at this time constituted.

Legislative reform was set on foot in 1833 by the "Lighting and Watching Act" of William IV.,[198] which provided that inspectors should be appointed and given a large measure of control over the local police establishments of all English towns with the exceptions of London, Oxford, and Cambridge; this Act was, however, of little permanent value,[199] and is only worthy of notice as the first attempt to provide a day police outside the metropolis. In the following year the whole question of charters, etc., was investigated by Special Commissioners, who issued a report embodying recommendations, which, for the most part, were given effect to by the "Municipal Corporations Act" of 1835.[200] After repealing all Acts, charters, and customs inconsistent with itself, this statute proceeds to create municipal corporations for the larger towns; such corporations to be styled "The Mayor, Aldermen, and Burgesses." The Mayor is declared to be a Justice of the Peace for the borough, and no property qualification is now required of him. The Common Law method of appointing constables is placed on a new basis, for the Act entrusts the making of Head and other constables to a body composed of the mayor and councilmen, called "The Watch Committee," the members of which are empowered, at their discretion, to make regulations for the management of the police, and to discharge or otherwise punish any constable found remiss in his duties, provided that three members at least are present when the award is made.

Borough constables are given powers to act in the county as well as in the town, and are authorized, not only to apprehend disorderly persons at any time, but during the night may take bail by recognizance from persons brought before them for petty misdemeanours, such recognizance to be conditioned for the appearance of the parties before the magistrate.

Watch Committees are required to provide station-houses, and every quarter must transmit to the Home Secretary a return shewing the number of men employed, the nature of their arms and accoutrements, together with an account of all salaries, clothing, and standing regulations for the forces; provision is made for the appointment, under certain conditions, of stipendiary magistrates at the request of the Council; the office of Borough Coroner is instituted; and finally, the Act requires two or more Justices to nominate and appoint by precept in writing, in October of each year, as many as they see fit of the inhabitants of the Borough to act as Special Constables there, whenever they shall be required by the warrant of a J.P.

The institution of special constables was a natural accompaniment to the general drift of circumstances which, for a long time, had been modifying English police. Originally, as we have seen, every free Englishman was compelled to take an active part in maintaining the peace: subsequently, by common consent and merely for the sake of convenience, the performance of police functions passed into the hands of individuals, either chosen or hired for the purpose, it mattered not which. As long as the principle of an inherent liability to universal service was generally well understood and acted upon, or, in other words, as long as the Sheriff's posse was available in emergencies, no legislation was required on the subject, because at Common Law a sufficient force of special constables already existed; but when this common responsibility for action was in danger of being forgotten, or, what amounts to much the same thing, when the existing machinery was incapable of giving effect to it, some new expedient had to be devised to take its place.

The first Act of Parliament authorizing the appointment of special constables was passed in 1673,[201] and was a tardy attempt to repair the havoc caused by the Civil War, but like many laws that found their way into the Statute Book during the seventeenth century, it might just as well have remained unprinted, for all the use that was made of it. It was not employed to restrain the Mohocks, nor to suppress the Gordon rioters, nor to save Bristol from the incendiaries. In 1831, however, began a sustained effort to systematize the overwhelming reserve of force at the disposal of the government of the country; this was the combined work of "The Special Constables' Act"[202] of 1831, of the "Municipal Corporations Act"[203] of 1835, and lastly of an Act[204] which became law shortly after the accession of Queen Victoria. These three Statutes dealt with the subject in detail, by defining what constitutes a special constable, by specifying his powers, and by stating when and by whom he is to be appointed. Between them they authorize "two or more justices, upon information on oath of any credible witness, that tumult, riot, or felony has taken place, or may be reasonably apprehended, such justices being of opinion that the ordinary officers are not sufficient for the preservation of the peace and protection of the inhabitants and property," to "nominate and appoint by precept under their hand so many as they shall think fit of the householders or other persons (not legally exempt from serving the office of Constable) residing in the parish or place or in the neighbourhood, for such time and in such manner as to the same justices shall seem fit," and ordain that they "shall send notice of such appointment to the Secretary of State and the Lieutenant of the county. Specials may act, not only in the parish or place for which appointed, but throughout the jurisdiction of the Justices appointing, and on the order of Justices of their own county, may act in an adjoining county."[205] Generally speaking, special constables have all the powers, and are subject to all the responsibilities, that ordinarily attach to police constables within their constablewicks.

The years 1829 and 1839 mark the limits of the most important decade in our police history. During this period of time the English boroughs acquired the means of securing themselves against the rising tide of crime which had threatened to overwhelm them; and an adequate defence against mob violence was made available by the legislation which restored, and reduced to a system, the power of the executive to enlist as many special constables as might be necessary for the maintenance of law and order. Whilst the former year will always be considered, and rightly so, as the most prominent landmark of the great revival from which dates an almost constant growth of police efficiency, the latter is hardly less noteworthy. 1839 not only saw the metropolitan forces for the first time firmly established on a permanent and satisfactory basis, it witnessed also the earlier stages of that movement in the rural districts which eventually provided the whole of England with a trustworthy constabulary.
