There appear to me to be insuperable objections to this view: on the other hand, I can hardly believe, in this and in some other cases, that these marginal crateriform mountains are merely the basal remnants of immense volcanos, of which the summits either have been blown off or swallowed up in subterranean abysses. From our elevated position we enjoyed an excellent view over the island.
I have marked with vermilion spots all the many known active volcanos within the limits of this same map.
Perhaps, when I have burned my bridges, I shall be mad for the very publicity I'm trying to escape. Women are like extinct volcanos; they are most to be dreaded when written perfectly harmless." Warrington shook his head and laughed. Here the coffee came in. He dismissed his man, and poured the nectar himself. "You are the one man I know who never asks to sweeten my coffee," she observed.
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.
In that country rocks before concealed may have become exposed by denudation; volcanos may have burst out and covered the surface with scoriae and lava; or new lakes, intercepting the sediment previously conveyed from the upper country, may have been formed by subsidence; and other fluctuations may have occurred, by which the materials brought down from thence by rivers to the sea have acquired a distinct mineral character.
One would have thought that warning enough: but the warning was not taken: and now, this very year, thousands more have been killed in the very same country, in the very same way. They might have expected as much. For their towns are built, most of them, close to volcanos some of the highest and most terrible in the world. And wherever there are volcanos there will be earthquakes.
When first I conceived my theory, naturalists were far from suspecting that basaltic rocks were of volcanic origin; I could not then have employed an argument from these rocks as I may do now, for proving that the fires, which we see almost daily issuing with such force from volcanos, are a continuation of that active cause which has so evidently been exerted in all times, and in all places, so far as have been examined of this earth.
Any instant a shock might happen which would destroy the "Albatross." Such a catastrophe became more probable as the wind shifted more to the east after they passed the prime meridian. Two luminous points then showed themselves ahead of the "Albatross." There were the two volcanos of the Ross Mountains Erebus and Terror.
Here one would expect our author is to allow that volcanos may erect rocks in heightening them in their place; but this is not the light in which it has been seen by him, as will appear from what follows. «L'enfoncement d'une de leurs cotés n'est rien, quand on considère le prodigieuse excavation qui ont dû se faire, pour porter au dehors toutes les montagnes, les collines, et les plaines volcaniques qui se trouvent dans ce vaste circuit.»
Hence such violent ebullition in volcanos, and hence the emission of so much pumice-stone and ashes, which are of the same nature. In the body of our whin-stone, on the contrary, there is no mark of calcination or vitrification.
