—These assemblagesof volcanos, whether in rounded groups or in
doublelines, show in the most conclusive manner that thevolcanic
agencies do not depend on small or restrictedcauses in near proximity to
the surface of the earth,but that they are great phenomena, of
deep-seatedorigin. The whole of the eastern part of the
Americancontinent, which is poor in metals, is, in its presentstate,
without fire-emitting mountains, without massesof trachyte, and perhaps
even without basalt containingolivine. All the American volcanoes are on
the sideof the continent which is opposite to Asia, in the chainof the
Andes which runs nearly in the direction of ameridian, and extends over a
length of 7,200 geogra-phical miles. The whole plateau or high-land of
Quito,of which Pichinca, Cotopaxi, and Tunguragua form thesummits, is
to be viewed as a single volcanic furnace.The subterranean fire breaks
forth sometimes throughone and sometimes through another of these
openings,which it has been customary to regard as separate anddistinct
volcanos. The progressive march of the sub-terranean fire has been here
directed for three centu-ries from north to south. Even the earthquakes
whichoccasion such dreadful ravages in this part of the worldafford
remarkable proofs of the existence of subterra-nean communications, not
only between countrieswhere there are no volcanos, (a fact which had
longbeen known), but also between fire-emitting openingssituated at
great distances asunder. Thus in 1797 thevolcano of Pasto, east of the
Guaytara river, emitteduninterruptedly for three months a lofty column
ofsmoke, which column disappeared at the instant when,at a distance of
240 geographical miles, the great earth-quake of Riobamba and the immense
eruption of mudcalled “Moya” took place, causing the death of
be-tween 30 and 40,000 persons.—Humboldt’s
