"Theory of the Earth, Volume 1 (of 4)"


Let us take a view of the most elevated places of the earth; if the
present theory is just, it is there that we should find volcanos. But is
not this the case? There are volcanos in the Andes; and round the Alps
we find many volcanos, which are in France upon the one side, and in
Germany upon the other, as well as upon the Italian side, where Vesuvius
still continues to exhibit violent eruptions.
It is not meant to allege, that it is only upon the summit of a
continent volcanos should appear. Subterraneous fire has sometimes made
its appearance in bursting from the bottom of the sea. But, even in
this last case, land was raised from the bottom of the sea, before the
eruption made its exit into the atmosphere. It must also be evident,
that, in this case of the new island near Santorini, had the expansive
power been retained, instead of being discharged, much more land might
have been raised above the level of the ocean.
Now, the eruption of that elastic force through the bottom of the sea,
may be considered as a waste of power in the operations of the globe,
where the elevation of indurated strata is an object in the exertion of
that power; whereas, in the centre of a continent sufficiently elevated
above the level of the sea, the eruption of that fiery vapour calculated
to elevate the land, while it may occasionally destroy the habitations
of a few, provides for the security and quiet possession of the many.
