[D8949AAZ], Letter from John Birkinbine to Thomas Alva Edison, May 3rd, 1889

Editor's Notes

I have just returned from quite an interesting visit to Canada, which I feel disposed to believe is the initiaitve measure for the erection of blast furnaces for the use of magnetic iron ore. The deposit which it is proposed to work is very rich ore, the drawback being sulphur, but as soon as an industry is established I think there are a number of lean ores in the vicinity which can be made available by concentration. I had an opportunity while in Ottawa your separator to Sir John. McDonald premier. Hon Machenzie Bowell Minister of Customs Mon W.G.Perley M.P. Sir Hames Grant and others, and I find that they are to a certain extent familiar with the experiments you have been making with the Canadian McKee ores. I have regretted very much that I was unable to see you before going to Canada as I wished to advise yo uas to the results of the experiments which were made with the Monarch and Wenstrom machines at Port Henry. I feel confident that the Edison machine will do what neither of the others have done, and I would strongly urge upon yo umaking such an experiment as would demonstrate this. I regret the misunderstanding which sees to exist in your mind regarding Messers Witherbees, Serhman & Co., and say frankly to you that I know no one with whom I would prefer carrying on operations than that firm. I have not yet received the proof of our paper on "Iron Ore Concentrations" but as soon as it comes I will bring it over and confer with you, or I will come over at any time when I can be of service. I letter has been referred to me from a party in Blacksburg S.C. who are desirous of becoming posted as to crucshing plant for concertating ores by the use of your machine.
