tests, and also arranging for the production of a low-silicon pig iron. 
This smelting test proved satisfactory. 
First Smelting Experiment. 
February 17th, 1916 
The electric smelting test was made in the furnace shown in 
Figure 1. It was fourteen inches long, nine inches wide, and fifteen 
inches high inside; built of fire brick, and held together by iron straps 
and bolts. The bottom of the furnace had a lining of coke and pitch 
rammed in while hot around the electrode C, and a tap hole D served 
for the removal of the molten metal and slag. Two electrodes A and 
B were supported by water-cooled holders carried by arms G and H, 
by means of which the electrodes could be raised or lowered in the 
furnace. The furnace was operated with three-phase current at 
about 30 volts. This arrangement was convenient in view of the 
electrical supply, but had the effect of raising the fusion zone too high 
between the electrodes and is consequently not recommended. It 
would be preferable to use single phase current with one upper elec- 
trode and a furnace about nine inches square. F is a water-cooled 
holder for the electrode C, and E is a mould into which the molten 
metal and slag are tapped. 
The ore employed in the aumelene 4 tests was obtained from the 
Orton mine, Hastings county, Ontario; being the same that was used 
some years before in experimenting on the Evans-Stansfield process 
for the production of steel, directly from the ore, in the electric fur- 
nace.! The ore was found to contain:
