CHANGE OF SHAPE OF RECENT COLLIERS. 153 



The Chairman : — .If there are no further speakers, we will consider the discussion 

 closed, and the author of the paper will have an opportunity, if he desires, to make a 

 written closure. 



Naval Constructor S. F. Smith (Communicated) : — The members who have spoken 

 in connection with this paper have brought out one of the points which I particularly hoped 

 would be raised, and that is, that there is a great deal of information on this important sub- 

 ject available which could be compiled and submitted to the Society, without very much dif- 

 ficulty. I trust that some of them who may be in a position to make such compilation can 

 be induced to undertake it. 



As regards Naval Constructor Tawresey's wish that I had gone on and shown a way 

 to get around the difficulties I mentioned, I would suggest that a great deal more informa- 

 tion is necessary before we can do much in the way of suggesting remedies. In fact, it may 

 be that remedies are not necessary and that these changes of shape are entirely harmless ex- 

 cept in extreme cases. 



The first observations were taken on the Neptune for the same reason that Mr. Tawresey 

 found it necessary to make observations on the destroyers, that is, to be able to ascertain 

 whether the vessel had been loaded for trial according to contract. It had been previously 

 learned in the case of the Cyclops that there was considerable change of shape which neces- 

 sarily raised the question as to what was the exact displacement of the vessel corresponding 

 to the observed draught. 



In view of the interesting remarks of Mr. J^rancis 'Smith, I trust he will at some future 

 date give the Society the results of the tests he refers to. 



There were a number of announcements made, after which the meeting adjourned for 

 luncheon.
