Here And There The Cone Of The Pyramid Would Be
Shaven Off, Leaving It Flat-Topped Like A Babylonian
Altar
Or Mexican teocalli; and as the sun's level
rays, - shooting across above our heads in golden rafters
from ridge to
Ridge, - smote brighter on some loftier peak
behind, you might almost fancy you beheld the blaze of
sacrificial fires. The peculiar symmetrical appearance
of these rocks arises from the fact of their being built
up in layers of trap, alternating with Neptunian beds;
the disintegrating action of snow and frost on the more
exposed strata having gradually carved their sides into
flights of terraces.
It is in these Neptunian beds that the famous surturbrand
is found, a species of bituminous timber, black and
shining like pitch coal; but whether belonging to the
common carboniferous system, or formed from ancient
drift-wood, is still a point of dispute among the learned.
In this neighbourhood considerable quantities both of
zerlite and chabasite are also found, but, generally
speaking, Iceland is less rich in minerals than one would
suppose; opal, calcedony, amethyst, malachite, obsidian,
agate, and feldspar, being the principal. Of sulphur the
supply is inexhaustible.
After steaming down for several hours between these
terraced hills, we at last reached the extremity of the
fiord, where we found the "Saxon" looking like a black
sea-dragon coiled up at the bottom of his den. Up fluttered
a signal to the mast-head of the corvette, and blowing
off her steam, she wore round upon her heel, to watch
the effects of her summons.
