Charles Dickens,
A Coal Miner's Evidence
(1850)
“ As for accidents from the explosion of gas, I say there's no help for them, and never can be, so far as the men themselves are concerned. I have been oftentime very careless myself, as I've told you, and so are all miners, and always will be. You may cure the mine of gas, perhaps, but you'll never cure the men. ”
