There was an eruption from this mountain on the 6th of August, 1853. It began by throwing up from the summit a column of fire and smoke, which ascended to a great height. This continued for five or six minutes, and was followed at short intervals by two similar eruptions.
Nature joined forces with mismanagement by the authorities; on the seas surrounding the island pack-ice frequently became a menace to shipping, and there also occurred unusually long and vicious series of volcanic eruptions.
It can by no means be inferred that trachyte predominated at one period of the earth's history and basalt at another, for we know that trachytic lavas have been formed at many successive periods, and are still emitted from many active craters; but it seems that in each region, where a long series of eruptions have occurred, the lavas containing feldspar more rich in silica have been first emitted, and the escape of the more augitic kinds has followed.
Pompeii lies to the south-east from the mountain, and Herculaneum to the south-west. Of course the lava, in breaking out from the crater in different eruptions, runs down the mountain, sometimes on one side and sometimes on another. It is the same with the showers of stones and ashes, which are carried in different directions, according to the course of the wind.
Many of the infectious fevers, such as measles, scarlet fever, chicken-pox, and smallpox, are attended by rashes, or eruptions, upon the surface of the skin, due to a special gathering or accumulation of the particular germs causing each disease, just under the skin.
Psoroptes communis var. equi seems to be the more common parasite. The itching is intense. After a time the small areas come together and form large patches, and further spreading of the inflammation results from grooming, scratching and biting the skin. Scattered, elevated eruptions on the skin from which the hair has dropped out are first noticed. These parts may show yellowish scabs.
What, then, must we expect when we come to the upheaved regions to the districts broken and roughened from volcanic eruptions and subterraneous commotions? We were to learn this all in good time. I saw, however, on consulting the map, that we avoided a good deal of this rough country, by following the winding and desolate shores of the sea.
The detonations heard during whole days together in the New World, eighty, one hundred, or even two hundred leagues distant from a crater, do not reach us by the propagation of the sound through the air; they are transmitted by the earth, perhaps in the very place where we happen to be. If the eruptions of the volcano of St.
No matter, the condition remains we're alive and all the rest are dead; and I'm positive this cleft here is the cause of it." "But if everybody's dead, as you say, why hunt for men?" "Perhaps a handful may have survived among the highlands of the Rockies. I imagine that after the first great explosion there followed a series of terrible storms, tornadoes, volcanic eruptions, tidal waves and so on.
The scenery is wild and bold, but sterile; and scattered around are stupendous hills of lava, the products of former volcanic eruptions, but which have, for ages, been cold and wave-washed. Arrived at Porto Grande, in the island of St. Vincent's, one of the Cape de Verds. The harbor is completely landlocked by the island of St. Antonio, which stretches across its mouth.
