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
