Industry Which Keeps the Big Guns Barking 



At right: Boring out the interior of 

 a shell body to make the thickness of 

 the body the proper dimension. 

 Many different sizes are made, vary- 

 ing from one and four-tenths to 

 sixteen inches, but the medium 

 sizes are in greatest demand 



At right below: A pile of rough 

 forgings from which the six-inch 

 shells are made. The shells shown 

 here would last but a few minutes in 

 one of those fierce offensives that 

 were daily occurrences in the early 

 autumn fighting and before Verdun 



At right below: After insF>ection 

 each shell is given two coats of 

 yellow enamel paint to prevent rust 

 in transit. The shells are hanging 

 by holes drilled in the nose piece. 

 When ready to load, the nose is 

 unscrewed with the aid of these holes 



Below: Testing the fitting of nose 

 piece to the shell body. The 

 rings shown on two of the shell 

 bodies are for checking the outside 

 dimension of the shells and the 

 gage-stick shown in the third is 

 used to get the depth of the bore
