SCAFFOLDING AROUND A SHIP UNDER CONSTRUCTION AT NEWPORT NEWS 



ROEEING STRUCTURAL STEEE AT BETHLEHEM, PENNSYLVANIA 



There are two cross-roads in the steel industry. All roads lead from the raw materials 

 to pig iron. Thence they branch out again to the puddling furnace, the open-hearth furnace, 

 the crucible furnace, etc. Then they converge again to the ins-ot, only to branch out once 

 more into the infinite variety of products of the roller mill. Pig iron has often been called 

 the common denominator of the iron industry, and the ingot the parent of all wrought steel. 

 Out of such mills as this will come the structural beams for the shipping that may decide 

 the issues of the world war.
