In 1829, desiring to increase their supply of water, the company obtained an act of Parliament, granting them authority to draw water from Lea Bridge Mills, and to add 120,000 to their capital. The water supplied by these various works, is conveyed to the height of seventy feet by steam engines. About 45,000 houses are supplied with 170,000 barrels daily by this company, which has laid down between 2 and 300 miles of iron pipes, some of which cost 7

guineas per yard, or 21 guineas, equal to $105, for a length of 9 feet. The pipes vary from 36 inches to 6 inches, but are mostly of large calibre. The greatest distance to which the works extend, is three miles, and although the the resistance from friction usually prepressure at the engines is estimated at 120 feet, yet vents the water from ascending higher than 60 or 70 feet. The expenditures of this company have been about half a million pounds. The south side of the Thames is supplied by two companies, the Southwark and the Lambeth, both deriving their supply of water from the river, pumping it up by steam

power, and distributing it through iron pipes.

PRELIMINARY ESSAY. 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.
