172 THE APPLICATION OF SMALL STEAM TURBINES, ETC. 



The next paper is No. 14, entitled, "Superheated Steam in Marine Practice," by Mr. 

 Henry B. Oatley, Member. 



Mr. Oatley presented the paper. At the conclusion of the paper, Mr. Oatley said : — 

 "Since the paper has gone to the printers, I have received a copy of what I think is one 

 of the most interesting papers recently presented. This was read on October 26, 1915, before 

 the Institution of Engineers and Shipbuilders in Scotland by Mr. James Dornan, entitled, 

 'On Some Alternating Types of Propelling Machinery for a Steamer.' I found it a most 

 valuable paper, and that the writer of that paper has gone into many topics which are under 

 very wide consideration at the present time. To anyone who is interested in the possibilities 

 of superheated steam, that paper contains much of interest. 



"Plate 95 was not as complete as I would like to have had it, but some data recently re- 

 ceived will be added and appear in the printed Transactions of the Society, which will make 

 this list of further interest. Some owners are reluctant in making public their test results and 

 this is to be regretted, as some very interesting data that I have cannot be given out for 

 this reason. This morning, however, I received permission to refer to a test that has been 

 made on a steamer operating out of New York Harbor. This is the Lehigh Valley's tug 

 Wyoming, and officials of the company stated that the economy shown in tests is 'in excess 

 of 15 per cent.' The Wyoming has triple expansion engines, and it will be noted that the 

 economy obtained checks very closely with the figures given in the paper."
