300 THE SPERRY GYRO-COMPASS IN SERVICE. 



very glad of the opportunity of testifying to their great efficiency for the purposes 

 intended, and their value in naval work. Mr. Gillmor is very optimistic, but in 

 my opinion he is not too optimistic. 



Mr. GiIvIvMOR (Communicated) : — This comment is especially valuable and 

 interesting. As Commander of the First Division of the U. S. Atlantic Fleet, 

 comprising the U. S. S. Florida, Flagship, and the U. S. S. Utah, Delaware and 

 North Dakota, Rear Admiral Fiske has had an excellent opportunity to observe 

 the operation of the Sperry gyro-compasses installed on these ships. His obser- 

 vation has extended not only to their use under ordinary conditions of navigation 

 but also under the conditions of target practice and fleet maneuvers. 



The Chairman :— We will proceed to the next paper on the program which 

 is entitled "Rudder Trials, U. S. S. Sterett," by Assistant Naval Constructors 

 R. T. Hanson and J. C. Hunsaker, junior members of this Society. 



The paper was presented by Mr. Hanson.
