He is thus slowly reaching the pointat which pig iron may be made by the electric arc at a price tocompete with coke. So far as the experiments at the Sault are concerned it maybe stated to-day, semi-officially, that Dr. Heroult has made con-siderable advances in the way of further economy, since beginningwork there a few months ago, and that both he and Dr. Haanalare enthusiastic as to the future of electric smelting of iron ores,where water can be used to generate cheap electric power. Tobe sure, Dr. Haanel, at least, does not expect coke furnaces to bedriven out, but he does look confidently for the employment of. PAUL LOUIS TOUSSAINT HEROULT Metallurgy al Notes and (omtnent 341 the electric furnace for special purposes and classes 6i steels andtor its gradual extension into the general field of ore is practically all that can be said at ibis tinn One of the most interesting experiments being carried ou1at the Sault during these trials is the smelting of roasted pyrrhotite ore (mono-sulphide of iron) directly into a ferro-nickel pig,all tin1 sulphur of the briquettes of pyrrhotite, amounting to 3per cent, being removed. The treatment of this class of ironsulphides, in distinction from pyrite, has been impossible was in part the costly and unsuceessful attempt to treatpyrrhotites for their sulphur and ferro-nickel, saving the sulphur,that led to the failure of the original Clergue company. For these Heroult experiments the Dominion governmenthas assisted to the extent of advancing $15,000, which Dr. Her-oult expects to return from the inco
