orms of water gas apparatus em-bodying the essential features of the Loweinvention found favor with some of the gasmanufacturers both east and west. Amongthese was the Springer process, whose dis-tinguishing feature was a generator and super-heater entirely enclosed in a single shell. Thechecker brick being sustained by arches abovethe fuel bed. This was the type of apparatusfirst installed for water gas making in SanFrancisco. Among the advantages claimedfor this method was economy of fuel. troduce oil in four streams. The oil and bluewater gas intermingle and pass through thecarburetter and the second superheater and arepermanently fixed. The double superheateraffords a much greater surface of heatedbrick for fixing the gas than the single one,and both the carburetter and superheater areheated by the products of partial combustionof the fuel from one fire bed. The use of the two superheaters permits arange of temperatures which would not bepossible in a single superheater, and it is

This was done by the UnitedGas Improvement Co., of Philadelphia, andthe improved set is known as the doublesuperheater apparatus which has becomethe standard in water gas practice. In this apparatus the first superheater isknown as the carburetter and the heated oilis admitted to the top of the carburetter in-stead of the top of the generator as in theearlier form, when it was the practice to in- therefore possible to successfully use oils ofdifferent densities and of complex composi-tions. The material used for water gas manufac-ture is governed by local conditions. In theeastern states anthracite coal is the best formof carbon for generator fuel, but when watergas is made as an auxilliary to coal gas, it iseconomical to use gas coke for this purpose. In California an anthracite coal importedfrom Swansea, Wales, wa
