STROM13OLI, the most northerly of the Lipari Isles. It is about ten miles in circuit. The popula tion of the island, amounting to about 1000 persons, are lodged in an irregular collection of cottages and fishermen's huts. A small portion of the island is cultivated, and the inhabitants arc chiefly occupied in fishing. Rabbits are here abundant.
The island consists of a single conical mountain, having on one side of it several small craters, one of which is in ceaseless activity, having in all probability continued so during the last 2000 years. The moun tain rises at an angle of nearly 40'. The crater is placed upon the slope of the precipice. The gaseous fluids escape from the volcano in successive explo sions, the greater ones at intervals of about seven minutes, and the lesser ones almost continually. The lava is thrown out only as projected scori2e, and is seldom or never discharged in any quantity. The in habitants assured Mr. I'. Scrope that in the storms of
winter the side of the cone occasionally split, and dis charged into the sea a current of lava which destroyed the fish.
Dr. Daubeny found that that part of the island not in the immediate vicinity of the volcano, was chiefly composed of a tuff. In one place the cavities were lined with very minute laminae of specular iron. The tuff is in some places penetrated by dykes of a cellular description of rock approaching to trachyte.
According to Mr. Scrope, the lavas of Stromboli have a high degree of fluidity, as their cellular nature shows, and also an extremely high specific gravity, being solely augitic.
