Artificial Earthquake And Volcano





Grind an equal quantity of fresh iron filings with pure sulphur, till

the whole be reduced to a fine powder. Be careful not to let any wet

come near it. Then bury about thirty pounds of it a foot deep in the

earth, and in about six or eight hours the ground will heave and

swell, and shortly after send forth smoke and flames like a burning

mountain. If the earth is raised in a conical shape, it will be no bad

miniature resemblance of one of the burning mountains.
