May 15, 1899. Prof D.S. Jacobus, Stevens Institute, Hoboken, N.J. Dear Prof. Jacobus, I have heard that the fact has been developed in Germany that a vertical engine when running on highly superheated steam, say 500 or 600 P- the interior rubbing surface of cylinder becomes oxidized and highly polished and requires no lubrication. Do you know whether this is so or not, and if so, where can I obtain reports of the tests: Thanking you for the information you can give me, I remain, Very sincerely yours, W.H. Dickson
