OF MEN-OF-WAR AND THEIR EMBODIMENT IN DESIGN. 83 



The submarine, relying on concealment to deliver its sudden attack is tactically akin to 

 fast-moving surface craft and air craft in that suddenness of approach and attack in them

The President: — It remains for the Chair to express, on behalf of the Society, its very 

 great appreciation of the time and trouble taken by Admiral Rodgers in preparing this 

 paper. 



The next paper, No. 2, is by Mr. Mason S. Chace, a life member of the Society. It is 

 entitled "Development of the Three-Plane Navy, with or without Battleships." We will 

 ask Mr. Chace to read an abstract of his paper. 



Mr. Chace presented the paper.
