And further, there is the Metropolis of the London City Mission, which extends to eight miles from the Post Office, and the Metropolis, again, of the London Ragged Schools, which reaches to about three miles from the Post Office.

This, however, is not all, for there are divers districts for the registration and exercise of votes, parliamentary, or municipal; there are ecclesiastical and educational districts; there is a thorough complication of parochial, extra-parochial, and chartered districts; there is a world of subdivisions and of sub-subdivisions, so ramified here and so closely blended there, and often with such preposterous and arbitrary distinctions, that to describe them would occupy more than a whole Number.

My present business, however, is the extent of the jurisdiction of the Metropolitan Commissioners of Sewers, or rather to ascertain the boundaries of that metropolis over which the Metropolitan Commissioners are allowed to have sway.

The many discrepancies and differences I have explained make it difficult to define any district for the London sewerage; and in the Reports, &c., which are presented to Parliament, or prepared by public bodies, little or no care seems to be taken to observe any distinctiveness in this respect.

For instance: The jurisdiction of the Metropolitan Commission of Sewers, which is said to extend to all such places as are not more than 12 miles distant in a straight line from St. Paul’s Cathedral, in the City of London, comprises an area of 452 square miles; the metropolis, that of the Registrar-General, presenting a radius of 6 miles (with a fractional addition), contains 115 square miles; yet in official documents 58 square miles, or a circle of about 4½ miles radius, are given as the extent of the metropolis sewered by the Metropolitan Commission. By what calculations this 58 miles are arrived at, whether it has been the arbitrium of the authorities to consider the sewers, &c., as occupying the half of the area of the Registrar-General’s metropolis, or what other reason has induced the computation, I am unable to say.

The boundaries of the several metropolises may be indicated as follows:—

The Three-Mile Circle includes Camberwell; skirts Peckham; seems to divide Deptford (irregularly); touches the West India Dock; includes portions of Limehouse, Stepney, Bromley, Stratford-le-Bow, and about the half of Victoria-park, Hackney. It likewise comprises a part of Lower Clapton, Dalston, and a portion of Stoke Newington; and closely touching upon or containing small portions of Lower Holloway, and Kentish-town, sweeps through the Regent’s and Hyde parks, includes a moiety of Chelsea, and crossing the river at the Red-house, Battersea, completes the circle. This is the six-delivery district of the General Post Office.

In this three-mile district are chiefly condensed the population, commerce, and wealth of the greatest and richest city in the world.

The Six-Mile Circle runs from Streatham (on the south); just excludes Sydenham; contains within its exterior line Lewisham, Greenwich, and a part of Woolwich; also, wholly or partially, East Ham, Laytonstone, Walthamstow, Tottenham, Hornsey, Highgate, Hampstead, Kensall-green, Hammersmith, Fulham, Wandsworth, and Upper Tooting. The portion without the three-mile circle, and within the six, is the suburban portion or the immediate environs of the metropolis, and still presents rural and woodland beauties in different localities. This may be termed the metropolis of the Registrar-General and Commissioners of Metropolitan Police.

The Twelve-Mile Circle, or the extent of the jurisdiction of the Metropolitan Commissioners of Sewers, as well as the “London District Post,” includes Croydon, Wickham, Paul’s Cray, Foot’s Cray, North Cray, and Bexley; crosses the river at the Erith-reach; proceeds across the Rainham-marshes; comprises Dagenham; skirts Romford; includes Henhault-forest and the greater portion of Epping-forest; touches Waltham-abbey and Cheshunt; comprehends Enfield and Chipping-Barnet; runs through Elstre and Stanmore; comprehends Harrow-on-the-Hill, Norwood, and Hounslow; embraces Twickenham and Teddington; seems to divide somewhat equally the domains of Bushey-park and of Hampton-court Palace; then, crossing the river about midway between Thames Ditton and Kingston, the boundary line passes between Cheam and Ewell, and completes the circuit.
