The quantity of ashes and cinders thrown during the eruptions was unprecedented. An analysis showed this discharge to be chiefly composed of iron, sulphur and magnesia. When dry the whole region seemed to be under a gray sheet, but after a fall of rain it appeared to have been transformed into an immense lake of chocolate. During the activity of the mountain several new craters had opened, especially on its north side and from which streams of lava flooded the beautiful, prosperous and happy land lying on the southeast shores of the Gulf of Naples. The whole of Vesuvius district as far as Naples, Caserta and Castellammare became one vast desert. The high cone of the volcano was almost entirely destroyed having been swallowed up, so that the height of the mountain is now several hundred feet less than formerly. Its falling in caused a great discharge of red hot stones, flame and smoke. Professor Di Lorenzo, the scientist and specialist in the study of volcanoes, estimated that the smoke from Vesuvius had reached the height of 25,000 feet. After one of the eruptions ashes from Vesuvius were noticeable in Sicily which is a large island near the extreme end of the peninsula on which Naples is situated and some 200 miles from the crater.

SCENES IN FRIGHTENED NAPLES. =Blistering Showers of Hot Ashes--The People Frantic--Cry Everywhere "When Will It End?"--Atmosphere Charged with Electricity and Poisonous Fumes.= From the first outburst and glare of the eruption all Naples became aroused and trembled with anticipations of horror, and when the hot ashes from the crater of Vesuvius began to fall in blistering showers upon it the entire populace was seized with a fear, which for days was constant, that at any moment they might be crushed into eternity by the awful outpourings from the cauldron of the mountain which was in truth as veritable an inferno as that pictured by Dante. The streets for days, even up to the subsidence of the eruption, were packed with surging crowds, all of whom were fatigued from fear and loss of rest, yet there was hardly one in all the thousands who had not strength enough to pray to the Almighty for deliverance. At times the fall of sand and ashes appeared to be diminishing, but in the next instant it came again, apparently in greater force than before. The city became frantic from fear and everywhere was heard: "When will it all end?"
