Apart from any advantage proper drains offer over cesspools, III V are more economical in construction and use, as the following Dmparative estimates show :— Estimated Cost of Cesspool for house, say, of bOL annual rental.

But a cesspool on the Paris plan ist be water-tight, and would cost the sum named, or even more. 1 nnnT*'^ 'Os. annually is saved upon 60,000 houses, the result will be a saving of •VfOi., or five times the annual per centage on the sum required for complete outlet iterceptirig sewers and drains, as given in the estimate at the end of this Report.
