    The question presents itself here—Is there sufficient fall from the city to the proposed outfalls 1 Prima facie, if there be fall for the river there is fall for the sewage in properly constructed conduits. Mr. Smith, to whom reference was formerly made, ascertained from levels taken by him, that the fall afforded ample run to carry down the whole sewage and'drainage of the city. This estimation may be held as conclusively settled, and that under official imprimatur, by levels taken by the late Mr Thomas Kyle, and indicated on his chart of the Clyde prepared for the Clyde Trustees, and published by Messrs. Maclure & Macdonald in 1838. Starting from Hydepark Ferry, marked The old Glasgow Fishery, to the mouth of theA*MM* Mr. Kyle gives the incline at/£ about 53 feet; and taking the length in as straight a line as possible at 18 miles, we have a continuous fall of nearly 3 feet per mile. From Springfield to Hydepark Ferry there cannot be less than from 3 to 4 feet of an equable fall. At page 29 of their report, Messrs. Bateman & Bazal- gette -ive 20 inches per mile for their scheme to the Ayrshire sands, as sufficient to prevent deposits and secure the minimum rate of flow in the sewers being never less than If feet per second, or 1J miles per hour ; and when full, or half full, 2| feet per second, or 1^ miles per hour. On Mr Kyle's measurements, these velocities would be nearly doubled in the proposed Clyde conduits. But giving effect to the obvious fact that the raising of the banks would affect the natural levels for discharge by gravitationfeven if necessary, it is here alone where motive power could be most fitly and innocuously introduced. _ The fatal objections to Z pumping stations at the Green and Pollokshields do not apply hem At present, both banks are remote from houses and places of sea-side resort the sewage would be much more diluted and to that extent [ess offensive ; the residuum in the wells, instead of being thrown into the river, could be lifted and spread over the banks, or utdised a, yet to l,e indicated in the alternative proposal*; and surrounded as the woiks tould be with thick foliage, nothing inodorous could pass even to the immediate neighbourhood. . . Before further detailing the scheme, it is necessary to remark that, as an es ential condition, and in order to restore the waters of the Clyde to lie their normal state, not a gill of sewage or waste or refuse benencenx commonly, almost wears the semblance of a veiy the main conduits formerly mentioned. ^ _mt leto And m: leads to a^secondEgSgiki, *>«• ^2 ffiSS* wSSSSSSSL o, toe 23k and Having M
