When I was a kid travelling with my Uncle, that's all they used in the Saw Mills.
Still remember the smell of the wood fired cook stove and all the delicious foods cooked in cast iron to this day.
Similar to my tanker days loading onto a ship up in the Soo.
Captain watches the circus for a bit and then addresses us. "You men (4) look hungry, come with me." Up onto the ship, walked to the front of the line, "Cook these men whatever they want, they are my guests."
They used gas, but the cast iron food was still amazing.
