June 27, 1891, H.M. Livor, Esq., Gen’l, Manager, New Jersey & Penn’s Concentrating Works, Ogdensburgh, N.J. Dear Sir:- Your letter of 25th instant is before me. Of course, the principal cause of loss in the tailings, is weak magnets, but Mr. Dickson tells me that these holes occur right along. He also tells me what you have not told me, that you are using a considerable number of 50 mesh screen plates, having neglected, I suppose, to order a supply for the future. Also learn through another source that you had to shut down Crusher at one time, having neglected to get a supply of oil. Yours very truly, Thos A. Edison
