THE BEGINNING OE A CARGO-CARRIER 



The keel having been laid, the keel plates and ribs are hoisted into position by the erectors 

 who operate giant cranes. Much of the assembling work is done in the steel mills, where the 

 plates and parts of the frame are made. In the left foreground are other assembled parts 

 ready to be hoisted into position and riveted.
