Its eruptions have been most considerable during the earthquakes which have desolated Sicily and a greater part of Italy. In the month of March, 1786, after subterraneous thunders and roarings, which were heard over all the islands, to the great terror of the inhabitants, and were accompanied by frequent concussions, the crater threw out a prodigious quantity of sand, mixed with immense volumes of smoke and fire. This eruption continued fifteen days, and so great was the quantity of sand ejected that the circumjacent places were entirely covered with it to a considerable hight. The lava did not flow at the time, at least over the edges of the crater; and indeed, such a current is not remembered by any living person. THE HIMALAYA MOUNTAINS. BETWEEN INDIA AND THIBET. “The great Himalayan snowy range,” says Mr. Fraser, “is only the high elevated crest of the mountainous tract that divides the plains of Hindoostan from those of Thibet, or Lesser Tartary. Far as they predominate over, and precipitously as they rear themselves above the rest, all the hills that appear in distant ranges, when viewed from the plains, are indeed only the roots and branches of this great stem; and, however difficult to trace, the connection can always be detected between each inferior mountain and some particular member of its great origin. “The horizontal depth of this mountainous tract, on that side which overlooks Hindoostan, is no doubt various; but, from the difficulty of the country, a traveler performs a journey of many days before he reaches the foot of the immediate snowy cliffs. The best observations and surveys do not authorize the allowance of more than an average depth of about sixty miles from the plains to the commencement of these, in that part of the country that forms the subject of this narrative. The breadth of the snowy zone itself in all probability varies still more; for huge masses advance in some places into the lower districts, and in others the crest recedes in long ravines, that are the beds of torrents, while behind they are clothed by a succession of the loftier cliffs. Every account we receive of a passage through them, (and this is no doubt found most commonly where the belt is narrowest,) gives a detail of many days’ journey through the deserts of snow and rocks; and it is to be inferred, that on the north-east side they advance to, and retreat from the low ground in an equally irregular manner. Indeed, some accounts would induce the belief, that long ranges, crowned with snow-clad peaks, project in various places from the great spine, and include habitable and milder districts; for, in all the routes of which we have accounts, that proceed, in various directions toward the Trans-Himalayan countries, hills covered with snow are occasionally mentioned as occurring, even after the great deserts are passed, and the grazing country entered. The breadth, then, of this crest of snow-clad
