Another controversial question concerned the distance apart at which wells in the red sandstone might affect the water-levels in each other by pumping. The result of the protracted fight, which occupied nineteen days, was that the Nottingham Corporation were defeated in respect of two of their proposed wells, and the Newark Corporation acquired possession, not of the zone of protection, bounded by an 8-mile circle, which they sought, but of a somewhat more restricted area, together with larger powers than would seem to have been granted in any previous case.1 26 May. 1897.--No. 1. "Carburetted Water-Qas."2 By Corbet Woodall, M. Inst. C.E. Allusion was made to the revolution brought about in the entire system of the supply of illuminating gas in the United States by the introduction of carburetted water-gas. It was not until 1890 that such gas was first made for distribution in this country by the Gas-Light and Coke Company at Beckton, and in 1897 the total quantity made in London and the provinces would probably reach 50,000,000 cubic feet daily, or 8 per cent. of the maximum output of the United Kingdom for lighting and other purposes. Water-gas was made by passing steam through a deep bed of incandescent coke or anthracite coal, and, while it was nonluminous when burned, its flame-temperature was even greater than that of ordinary coal-gas. Carburetted water-gas was prepared for lighting purposes by introducing into the water-gas in process of manufacture a hydro-carbon oil or distillate in quantity varying with the illuminating value desired. The plant employed for the manufacture was explaine...
