Helen was asking the site supervisor about the progress of the factory, when she saw a boy, about fourteen or fifteen, wearing a black coarse fabric tight-fitting jacket, running towards her. Her face suddenly showed a kind smile.
That was her grandson Friedrich, a very talented child who, at the age of thirteen, had performed precision forging with the technicians without anyone teaching him.
"Grandmother," Friedrich waved enthusiastically and shouted from afar, "The latest results of the bending and forging tests of the newly produced grey cast iron are excellent!"
Helen was also very surprised: "Really? Those French people have been here for less than ten days."
The boy nodded, panting: "The tests were supervised by me personally. The bending performance has improved by 70% compared to our previous wrought iron. According to the French technicians, the phosphorus content in the molten iron from the blast furnace has been reduced by more than half."
