Sometimes these cling together above the lava stream, and make a tunnel, through the cracks in which you may see the fiery river rushing and roaring down below. But mostly they are kept broken and apart, and roll and slide over each other on the top of the lava, crashing and clanging as they grind together with a horrid noise.
We observe, indeed, phenomena on the shore near Torre del Greco which seem to require the belief that currents of lava had been solidified there at some period before the construction of certain walls and floors, and other works of Roman date.
The earthquakes began and grew until all down America from the Arctic Circle to Cape Horn, hillsides were sliding, fissures were opening, and houses and walls crumbling to destruction. The whole side of Cotopaxi slipped out in one vast convulsion, and a tumult of lava poured out so high and broad and swift and liquid that in one day it reached the sea.
This ever-moving lake of molten fire is called: "The House of Everlasting Burning." This surging lake was dotted with tiny mountain islets, and, from the tops of their little peaks, pyramids of flame blazed and columns of grey smoke went up. From some of these little islands streams of blazing lava rolled down into the lake of fire. The air was filled with the roar of the furnaces of flame.
The vapor whirled in the air to an immeasurable height, as if the valves of an immense boiler had been suddenly opened. But, however considerable might be the volume of water contained in the lake, it must eventually be absorbed, because it was not replenished, while the stream of lava, fed from an inexhaustible source, rolled on without ceasing new waves of incandescent matter.
PAHOEHOE AND AA. When the crust of highly fluid lava remains unbroken after its first freezing, it presents a smooth, hummocky, and ropy surface known by the Hawaiian term PAHOEHOE. On the other hand, the crust of a viscid flow may be broken and splintered as it is dragged along by the slowly moving mass beneath.
Dimly I could see the forms below being swung into place with a clock-like regularity and from numerous spouts great streams of concrete poured like flowing lava. It is at these building sections that the bombs were aimed and here alone that any effectual damage could be done, but the target was a small one for a plane flying above the reach of the German guns.
The analogy between geysers and volcanoes has frequently been noticed and the former have often been described as volcanoes which erupt heated water instead of melted lava. We have italicized the word hot in the definition just given, because springs containing a large amount of gas may simulate geysers.
Living as they do amid the grandest phenomena of nature, and tinctured with the wild traditions of the old Norsemen, it is not surprising that they should implicitly believe in wandering spirits of fire and flood, and clothe the desolate wastes of lava with a poetic imagery peculiarly their own.
They sat down beneath an oak: Falkland stooped to kiss the cold and pale cheek that still rested upon his breast. His kisses were like lava: the turbulent and stormy elements of sin and desire were aroused even to madness within him.
