The Southwark Company supplies about 7,000 houses daily with 1,500,000 gallons of water, on a capital invested of 66,400. The Lambeth Company, whose works are situated in the Belvidere Road, a short distance from Waterloo Bridge, supplies some 16,000 houses with 1,500,000 gallons. This company has incurred considerable expense, by constructing reservoirs on Brixton Hill, one at an elevation of 150 feet above tide and two others at different and lower elevations, one of which was & filter er, and transmitted the water to the other much purified.

One other enterprise only remains to be noticed The South London Water Works, for which a charter was obtained in 1805. The principal establishment is on Kennington Common, near Vauxhall, and, like the other works, it derives its supply from the Thames, and raises and distributes it through iron pipes, by steam power. The main of this company was, in 1832, laid into the Thames, of the largest iron four feet diameter, pipe any where employed probably in water-works. The water flows through this main into a reservoir in Kennington Lane, from which it percolates through a filtering bank, composed of layers of coarse and fine gravel and sand, prior to its entering into another reservoir, where it also remains some time, before it is passed into the well of the

distributing steam engine. The supply of this company extends to 12,000 houses, and exceeds 5,000,000 gallons daily.

To complete this view of the works, which supply London and its suburbs, containing probably nearly 1,200,000 inhabitants, we annex, in a tabular form, extracts from a more extended return, made by these companies in 1834, to Parliament. It exhibits the
