“At length we stood on the edge of the flat ground reaching to the foot of the cone. Currents of lava were running down on both sides of us far below; the craters from which they flowed were hidden by the smoke; clouds of smoke were ascending from the top of the cone, and the lava still pouring down the Atrio. The roar of the mountain, which we had first heard at Portici was now tremendous, continuous, and unlike anything else I ever heard,—millions of peals of thunder rolling at the same time,—when suddenly, about noon, there was a cessation, with a low, rolling sound; and one heard the ticking and rippling of the lava currents pouring down the hill-sides below. Then, in about a minute, came a deafening roar, shaking the ground under our feet; and a new crater burst forth just on the other side of the Observatory, as it seemed to us, and dense clouds of ashes and stones were thrown up into the air on the left hand of, and mingling with, the great white cloud, making a great contrast with the dark-brown dust and ashes, which rose perpendicularly to an immense height. The roaring continued and kept on increasing till it became deafening, and I began to think it might injure our ears. We staid there about an hour and a half. [Sidenote: A MAGNIFICENT SCENE.] “The scene was magnificent, the smoke occasionally clearing away and giving us the view towards the Atrio, that towards the cone being always clear; but as some of our party fancied that the ground might open under our feet, and that we might find ourselves in the midst of a new crater, I at length reluctantly sent the guide to bring up the carriage. Had I been alone I should have staid there till the evening. When we had gone down a short distance the same phenomena again appeared. The sudden cessation of the tremendous roaring, the clicking and rippling of the falling lava, and the low muttering became then again audible; then the fearful roar, and the shaking of the ground, and another crater burst forth on the flank of the mountain, below the Observatory, sending up clouds of dust and ashes, which rolled over and over till they reached an enormous height, but quite separate from the other clouds. All this time the sun was shining in an Italian sky without a cloud.
