 Either of these are much slower than the 

 latest destroyers, but again the fastest war- 

 ship travels at less than half the pace of

 the speed record. Since her misadventure 

 and loss she has been doing splendid trips 

 under Mr. Kaye Don. 



Here are a few facts about this superb 

 speed boat. In the first place her engines 

 develop 4,000 horse-power, yet her pro- 

 peller is quite a tiny affair, but it turns at 

 12,000 revolutions a minute! The stem 

 of the boat is of stainless steel, and its edge 

 is like a razor.
