Feb. 21, 1894. L. A. Hotchkiss, Esq., Charlotte, N. C. Dear Sir:-- The sample of tin ore referred to in your letter of 16th inst. has been received by me, and I beg that you will accept my thanks for same. I only wanted the sample to familiarize myself with it. My forte will not be tin mining - that’s too uncertain. Yours very truly, Thomas A. Edison M.
