ENGINEERING PROGRESS IN THE U. S. NAVY. 95 



for over-running the destroyers and making more speed than the destroyers were 

 designed for, going up as high as 33 knots ; on the other hand he advocates very 

 strongly the over-driving of our battleships, making a couple of extra knots on the 

 battleships, but condemns in strong terms the over-driving of the destroyer. I 

 think I would rather take chances on over-driving the destroyer than the battleship, 

 and we are driving them hard, and we will probably keep at it for some time, until 

 we see what we can get out of them. 



In regard to the turbines, Mr. Anderson misunderstood the meaning of Captain 

 Dyson's paper as I interpret it. I think there is no contention in this paper, as 

 Mr. Robinson stated very clearly, for ships of high speed or large power, in favor 

 of the reciprocating type of engine, and I am quite sure, from my dealings with 

 Captain Dyson, that he did not mean that at all. The turbine scouts are much 

 more reliable at full speed, and the reciprocating scout is considerably more eco- 

 nomical at low speed, and as to the times that the ships have been in the navy yard, 

 it is undoubtedly a fact that the turbine ships have been at the yard for repairs 

 many more times than the reciprocating vessel, but that is neither here nor there, 

 and should not operate against the turbine, as we must remember that these are 

 the first two turbine vessels built by us, and we have improved on the design and 

 management, and everything else connected with the turbine. 



As to the question of space in the engine-rooms, that might be a little misleading. 

 The Texas and New York have very large spaces in the engine-room, but they were 

 originally laid out for turbine machinery, and probably we took an unfair advantage 

 of Admiral Watt. An engineer likes a lot of room in the engine-room, and we are 

 loath to give up a square inch of space, and when Mr. Bailey came along with the 

 reciprocating engine it looked so good to us for the space we had in that it makes a 

 good open engine-room, with space everywhere. I think Mr. Bailey will bear me 

 out 



Mr. Bailey: — We did not object 



Admiral Cone :— I think Mr. Robinson and Admiral Watt are the two losers 

 in that deal, and it is somewhat unfortunate that I have had to confess it. 



I want to agree with Mr. Robinson in his statement about designing to the speed 

 you expect to make. In our service we design a ship for 21 knots, and that is what 

 our strategists want, and they make allowances for excess speed, etc., when they see 

 fit. They want a ship that makes 21 knots, and in the case o'f the destroyer it is 

 the same way. In other words when you lay down a ship for 29.5 knots, build it 

 for that, and not have 4 or 5 knots up your sleeve. It is not good designing, and 

 it is not good business. 



As to the removal of the cruising turbines, I do not remember what was said, 

 but they were removed as a matter of experiment so to speak, to see what effect 

 it would have, and as far as we could judge it had no detrimental effect on the 

 turbines. 



If I may be permitted, I would like to say "Good afternoon." (Applause.)
