Electrical news and engineering . By I). Hobfitson Experinients were made, under the Dominion Govern-ment supervision, at Sault Ste.

These preliminary ex-periments were regarded as satisfactory but no further ex-perimentation was proceeded with in Canada. In Sweden, however, where the conditions governing theiron industry are similar to those in several provinces ofthe Dominion of Canada, the question of Electric Iron. Fig. 1 Smelting was taken up in UIOO. Three Swedish engineers,Messrs. Gronwell. Lindblad, and Stalhane, commenced ex-pciiments, and after overcoming many preliminary difficult-ies succeeded in the summer of 1908 in constructing a fur-nace which was durable and gave a good output. Profiting by their experiences, they determined to buiida furnace of 700 at Domnarfvet, in order to test thecommercial feasibility of the furnace. The experiments with this furnace were witnessed byDr. Eugene Haanel of the Government Department of Minesin Ottawa, and in 1909 a report was issued giving the re-sults. So impressed were the Swedish Ironmasters with theworking of this small Gronwall reduction furnace that theSwedish Association of Ironmasters, Jern Kontoret, de-termined to erect a furnace of 2.)00 at idea was to thoroughly test the furnace on a com-mercial scale. This furnace was started in Xovember 1910. Variousconsignments of ore were sent from the ditTerent mines ofS
