The habits they thus acquire are the most mischievous and noxious to the Community that can be conceived.--Having connexions wherever the Dock-yards are situated, as well as in several other large trading towns in the Kingdom, they become in many respects the medium through which stolen goods are conveyed to and from the Metropolis; and as their existence depends on this nefarious traffick, they keep alive a System of Fraud and Depredation which, perhaps, is generated in a greater degree by their peculiar situation in respect to Society, than by any actual disposition on their parts to pursue these nefarious practices. Even the system of supporting the poor of this Community, by lending them small sums of money by which they may support themselves by a species of petty traffick, contributes in no small degree to the commission of crimes; since in order to render it productive to an extent equal to the wants of families who do not acquire any material aid by manual labour, they are induced to resort to unlawful means by dealing in stolen goods and in counterfeit money, by which they become public nuisances in the Countries where they receive an asylum. As there appears in reality to be no distinction made by the rational part of the Jewish persuasion, between the Portuguese and the Dutch Synagogues, it is earnestly to be hoped that the opulent and respectable of the former Community will lend a helping hand in devising some means of rescuing this part of the Nation of the Jews who reside in England, from the reproach, which it is to be feared, has been too justly cast upon them. Policy dictates the measure, while humanity ardently pleads for it.--In so good a work every man of feeling, be his religious persuasion what it may, will join in promoting and carrying into effect a measure so beneficial to the Community at large, by devising some means to render their labour productive; since it is clear to demonstration that to the idle habits of this numerous class of people, is to be ascribed a considerable proportion of the petty crimes, as well as some of the more atrocious offences by which the Metropolis and the Country is afflicted. _Another cause_ of the increase and multiplication of crimes has arisen from the depraved morals of the Aquatic labourers and others, employed on the wharfs and quays, and in ships, vessels, and craft, upon the River Thames; and from the want, _until lately_, of an appropriate Preventive System to check these depredations.
