March 13, 1900 Messrs C.K. Williams & Co., Easton, Penna. Dear Sirs:-- Replying to yours of the 8th inst. which has been forwarded from our Edison Works, we beg to state that we use entirely chilled iron made of a special mixture of our own. As we understand Manganese steel, it is not so hard as chilled iron, but it is tough, and not knowing the peculiarities of your material, we are unable to decide as to whether it would last longer than chilled iron. In addition to this, we have hardly tested Manganese steel enough to give any decided opinion on it, but we believe in the long run chilled iron of the mixture we use will be cheaper Yours very truly, W.S. Mallory V.P.
