Is the Order Given to the Coast Artilleryman 



A big gun at the moment of firing. It has been elevated into position before firing, and 

 immediately afterward it falls back out of sight on its supporting members. The 

 two-ton shell it has hurled off into space can penetrate the thickest armor 

 of any battleship that may dare to poke its nose within a dozen miles of our coast 



"Tactics change 

 every ten years," 

 said Napoleon. 

 Before the war our 

 coast artillery was 

 practising at ten 

 thousand yards ; 

 now the range has 

 developed into 

 twenty thousand 

 yards and more. 

 The energy neces- 

 sary to fire a shot 

 from the gun in 

 the picture con- 

 tinued from the 

 preceding page 

 would project your 

 two-ton automobile 

 twenty-seven miles 

 in less than twice 

 as many seconds
