- Editor's Notes
- Dear Sir, I was much interested in Mr. Edison ideas in theories regarding the separation of our ores and new concentrator. As I have not not seen the deposit in New Jersey which Mr Edison proposes to work I cannot form any opinion of it. I gather however that it is a large exposed deposit of very lean ore, say 27% and that he would obtain about 330 tons of concentrated ore from 1000 tons of the mixed ore and rock. Now that means the hauling of an immense quanty of refuse that is neither food for man nor beast. On general principles it would strike me that that if one had a good vein of Iron ore from which fully one third of it woould be 64 to 65% and readily marketable without concentration at a price which would more main than cover the cost at a minimum the entire [three thirds?] it would be preferable to a lease deposit. That would be the situation with regard to the largest and best vein at ore mines. Like all geniuses Mr. Edison will probably have to earn at his pet theories to a proctical issue when he will be able to take new bearings and discard the unprofitable theories if any which he may find to exist. I will see you further in regard to this matter as I do not want it to drop. Yours faithfully, John N. Glidden [marg: No answer]
