SUPERHEATED STEAM IN MARINE PRACTICE. 199 



the triple expansion engine. In tiie absence of these materials, compounding, either in one 

 or more stages, naturally became much more attractive. 



It is flattering to the writer to feel that the discussion of this paper to-day has brought 

 out so much that is in the line of agreement with the sentiments expressed in the paper. I 

 believe that all of the speakers have expressed their belief in the coming of superheated 

 steam, though the means for accomplishing it in the near future may not accord fully with 

 the writer's personal views. It is also pleasing to have Mr. Anderson bring out a most 

 important point in connection with the use of superheated steam in turbines. I felt that the 

 paper was lacking in this respect, and as Mr. Anderson is probably one of the leading 

 authorities in this country on turbine design I think his remarks are of particular value. 



The President : — I am sure the thanks of the Society are due and most willingly 

 given to Mr. Oatley for his very interesting paper. 



We will now take up the last paper to be considered at this meeting, No. 13, entitled 

 "The Submarine of To-day and To-morrow," by Mr. L. Y. Spear, Member. In the absence 

 of Mr. Spear, the paper will be presented by Mr. Eric H. Ewertz. 



Mr. Eric Ewertz, Member: — Mr. President and gentlemen, I wish that the author of 

 this paper could have been here to read it himself, as he is ever so much better qualified to 

 bring out all of the interesting points. In order to take up the least possible time I will read 

 the paper in abstract, referring to what I consider may be of the most interest to you on this 

 question of submarines.
