(To tlio Edltor.l ! pir,—lt. i» not ihe natural destiuy o: ' the solid sewage of a town to be tumor nto the harbour, perhaps to help to sill t up, but to form a valuable natura isset to be placed on the land, and help it to produce food for man nnd beast Inroad of going to the great expense ol introducing a new system, why nol utilise the present one. By forming brick or eoneretc tanks at the mouth; of the present sewers, large enough tc hold the sewage output for six hours ffllli the bottom of the tanks Vwt that the sewrrs, so as to intercept the solids continuing sewer or pipes to below low writer line, covering tanks with light 1 iron girders and stone or concrete slabs properly ventilating tank?- Let th« water run out from time of high tide and by low water time T suppo-e the sewajre would be carried beyond Tir: and dispersed in nil direction*, never tr return. It would not require any ehemi cal treatment. The solid could be carted away in carts, barges, or railway truck; , , nnd distributed on now value lesT ground, making it fertile. Or Shoal Bay r>r Cox's Creek could be recliimed the Pfvwage deposited there, producing rich lntid. In years to conic a collectin % sewer could be formed from Cox"? Creek alons; the foreshore to say Hob son B."y. One large tank formed there, and the liquid let. out opposite Rang! toto Channel. Of course an overflow would be provided for storm water. ] know <i A town in England larger than Auckland, much of it very little above high water, on a river eight miles froir the Tir-rbour where this scheme has been carried on .for 25 years.with perfect success and very little expense. —I am. etc., POM.
