Rise of the Rajas Edit
“When sources of gold and silver near the surface were exhausted, miners developed technology for going deep underground. This involved building lifts to send men down and bring ore up. It required pumps to pull water up and push air down. And it required new tunneling techniques for shoring up mine galleries and shafts to prevent cave-ins. Some of the richest silver mines were found in Eastern Europe.”
