    may be fairly drawn, as between the initial and annual cost of works actually carried out by me, and the estimated initial and annual cost of a counter-scheme, on the old lines—which had been submitted to the Corpora- tion of Henley, and had been rejected, before I was commissioned to prepare my scheme, which was accepted. The rejected scheme embraced the taking into the sewerage system, (1) sewage proper, (2) subsoil water, and (3) half an inch of rainfall in twenty-four hours. This was a pumping scheme, and the maximum quantity of sewage, subsoil water, and rainfall estimated to be pumped was 192-6 cubic feet, or 1,204 gallons per minute. The accepted scheme is on the “separate system,” and when all the main sewers were completed they were practically free from subsoil water. The Corporation, very wisely indeed, have passed a bye-law strictly prohibiting the passage into the sewers of rain- fall and other waters, which would not, if allowed to flow into the Thames, unreasonably pollute it. By thus adopting the separate system, the maximum quantity of sewage-proper, unavoidable leakage, and unavoidable rainfall, which will have to be dealt with, has been estimated to be 250 gallons per minute only, or just the ^-th of the quantity provided for in the rejected scheme. The estimated cost of the rejected gravitation and pumping scheme on the old lines, as given by the engineer of that scheme, is stated below; as is the cost of equivalent works actually carried out on the Shone System. 3*
