SURFACE CONDENSERS. 115 
plates or baffles as a finality by any means, neither do I require any pointers from him 
as to where to put vacuum gauges on a condenser. 
Furthermore, he states that “‘we know the actual performance of this condenser 
is not as good as for the condenser of the standard stationary design.” I challenge him 
to prove this statement. 
Plate 42 shows clearly an innovation in condenser design for battleships and the like 
that seems to have been lost sight of altogether in the discussion of my paper. This 
represents truly what can be termed ‘“‘zone condensation” which, despite the fact of 
absence of proof of its value at the present time, will, in my opinion, mark a new era 
-in surface condensers for battleships and the like where full power is used but for a small 
fraction of the time. 
I hardly think that any engineer will venture to say that the subdivision of the 
surface condenser into a primary and secondary zone will not show its importance at 
reduced engine speeds as this would be contrary to our natural laws. Is any engineer 
going to be foolish enough to try and prove the value of condensate falling on tubes 
through which cold water is passing? 
THE CHAIRMAN :—The hour for closing the morning session has arrived. The other 
three papers will be read this afternoon at two o’clock. I call the attention of the mem- 
bers present to the excursion tomorrow to the Federal Shipbuilding Company’s plant 
at Carnegie, New Jersey. The steamer will leave the Pennsylvania Railroad Pier, 
at the foot of Cortlandt Street, at nine o’clock. Captains of steamers have some ad- 
vantage over the members of the Society—the members meet when they get together, 
but the captains leave when the bell strikes. Tickets may be obtained in the office 
of the Society at Room 604. A luncheon will be served on board. 
The Federal Shipbuilding Company will have a reception committee, with badges, 
to show the visitors over the plant. I also understand, through Mr. Smith, that the 
visitors will have the opportunity to observe the launching of a vessel there tomorrow. 
There will be a meeting of the Council of the Society immediately after adjourn- 
ment in this room. We will meet again at two o’clock this afternoon. 
The meeting then adjourned.
