Starting with just enough fuel placed below the boiler to get the water to boil with a row of workers ready to pass new blocks of firewood if everything would go all right, all the way to the set of valves for the steam, capable of forcibly shutting the entire machine down from a simple bunker wall twenty meters away made with a thick layer of the earth laid on both sides with a set of hardwood logs.
