All things are on fire. And what are all these things which are on fire?
The street is on fire; the gas station is on fire; Great sinkholes are on fire; buildings are on fire; and whatever burns, be it animal, vegetable, or mineral, that also is on fire.
And with what are these on fire?
With the fire of coal, say I, with the fire of anthracite, with the fire of gas and minerals dwelling beneath the earth; with carbon, hydrogen, oxygen, nitrogen and varying amounts of sulphur are they on fire.
The moral of the story is, to paraphrase Smokey the Bear: “Nobody can prevent giant underground fires.“
