The Chairman.- — Just a few words in closing. There is not a man in this room, indeed 

 I doubt if there is a member of the Society, who can say as I can, that my first trip across 

 the Atlantic and return was made on an iron single-screw steamship having a two-cylinder 

 low-pressure engine geared to the propeller and run with a maximum steam pressure of 25 

 pounds per square inch. 



When I went an as apprentice in the old North River Iron Works on West Street in 

 this city, an old feed store changed into a machine shop, there was under way the engine of 

 the steamer John L. Hasbrouck— following the one in the Daniel S. Miller built two years 

 before — a beam engine placed athwartships and geared to the propeller. 



Now, as one who has come from those primitive years and has seen the simple engine, 

 the compoimd engine, the triple, the quadruple and even the quintuple expansion engine 

 down to the great advances in other forms made within recent years, I can truly say the 

 papers and the discussion we have had presented to us tonight excite my highest admiration. 



You are all to be congratulated that you see progress in the making and can look for- 

 ward to still further progress. 



Feeling that the men who have taken the time and trouble to prepare these particularly 

 interesting papers, also those that have so carefully prepared their discussions, are fully 

 entitled to an expression of your appreciation, I now, on your behalf, extend to them sincere 

 thanks. 



The meeting is now adjourned. (Applause.) 



Whereupon at 11.25 p. m., the meeting adjourned sine die.
