March 22 1893. W.F. Taylor, Esq., Div. op’r Pennsylvania Railroad Company, Altoona, Pa. Dear Sir:- Your letter of 19th instant, In regard to the use of underground cables by the Pennsylvania Railroad Company, is before me. I had supposed here I received your letter that this subject had been dropped by your people. I have no longer any financial interest in the matter, but will say that I should very much like to see the Pennsylvania Railroad Company pioneer an underground cable, which if the base plan is correct, would I believe prove such a success that it would be an epoch in the business. It cannot be done, however, in a hurry. I am willing to aid by giving the results of the experience which I have had with interference and retardation, acquired by years of experimenting on Automatic and Quad systems. The best way would be to have a Committee of one or two gentlemen come to the Laboratory, with all the data, and spend an afternoon with Mr. Kennelly and myself. We could then look into the matter carefully. Yours very truly Thos A. Edison
