1st. The prevention of crimes and misdemeanors, by bringing under regulations a variety of dangerous and suspicious trades;[170] the uncontrolled exercise of which by persons of loose conduct, is known to contribute in a very high degree to the concealment, and by that means to the encouragement and multiplication of crimes.

To raise a moderate Revenue for Police purposes from the persons who shall be thus controlled, by means of Licence Duties, and otherwise so modified as not to operate as a material burden; while a confident hope is entertained, that the amount of this revenue will go a considerable length in relieving the finances of the country, of the expences at present incurred for objects of Police, and that, in the effect of the general System, a considerable saving will arise, in consequence of the expected diminution of crimes, particularly as the chief part of the expence appears to arise after delinquents are convicted.[171] [Footnote 171: The amount of the general expence of the Criminal Police of the Kingdom as stated by the Committee on Finance in their 28th Report is as follows: 1st. The annual average of the total expence of the Seven Public Offices in the Metropolis, from the institution in August 1792 to the end of the year 1797, being a period of 5-1/2 years £.18,281 18 6
