June 13, 1891. H.M. Livor, Esq., Gen’l. Manager, N.J. & Penn’s Concentrating Works, Ogdensburgh, N.J. Dear Sir:- Your several letters of 11th and 12th instant are at hand, and I have noted contents of same. If your ore is dry as you say. Why do you have 4% & 5% loss in tailings? This shows something wrong. I note what you say in regard to experiment with heater and about playing the hose on stock pile. I think you will have a rain storm, and you can then feed only fines from your stock pile; this would be better than wetting. In regard to my going up to Ogden. I am so very busy now, it is difficult for me to get away, but I will try and do so. Washing ore reduces phosphorous half; hence dust from 2nd mill will certainly run it lower. I note that you have an order for a car load of the extremely fine float of Mill No. 2; I have read your remarks in regard to this fine dust, and the same are O.K. Yours truly, Thomas A. Edison M[aguire].
