Page 330 - Behold, I am against thee, O destroying mountain, saith the Lord, which destroyest all the earth: and I will stretch out mine hand upon thee, and roll thee down from the rocks, and will make thee a burnt mountain.
Page 330 - Oh that thou wouldest rend the heavens, that thou wouldest come down, that the mountains might flow down at thy presence. As when the melting fire burneth, the fire causeth the waters to boil, to make thy name known to thine adversaries, that the nations may tremble at thy presence !

In the same manner this volcanic ebullition goes on without interruption, throwing up a globular body of mud, and dispersing it with violence through the neighbouring plain.
Page 402 - After walking some distance over the sunken plain, which in several places sounded hollow under our feet, we at length came to the edge of the great crater, where a spectacle, sublime and even appalling, presented itself before us —
Page 257 - Near to a vault, which is now thirty feet below ground, and has, probably, been a burial place, there is a draw-well, where there are several strata of lavas, with earth to a considerable thickness over the surface of each stratum. Recupero has made use of this as an argument to prove the great antiquity of the mountain. For if it require two thousand years or upward, to form but a scanty soil on the surface of a lava...
