They will dump four loads of red ore into the furnace; then you throw in a layer of coke and limestone, the latter being called 'flux.' This makes what we call the charge. Is that clear?"

"Yes. What do I do then?"

"You do it all over again and you keep doing it until another man comes to take the job off your hands."
