Two Days Afterwards A Stream Of Lava, Issuing From Sources
To Which No One Has Ever Been Able To Penetrate,
Came
sliding down the bed of the dried-up river, and in a
little time, - though the channel was six
Hundred feet
deep and two hundred broad, - the glowing deluge overflowed
its banks, crossed the low country of Medalland, ripping
the turf up before it like a table-cloth, and poured into
a great lake whose affrighted waters flew hissing and
screaming into the air at the approach of the fiery
intruder. Within a few more days the basin of the lake
itself was completely filled, and having separated into
two streams, the unexhausted torrent again recommenced
its march; in one direction overflowing soiree ancient
lava fields, - in the other, re-entering the channel of
the Skapta, and leaping down the lofty cataract of
Stapafoss. But this was not all; while one lava flood
had chosen the Skapta for its bed, another, descending
in a different direction, was working like ruin within
and on either side the banks of the Hverfisfliot, rushing
into the plain, by all accounts, with even greater fury
and velocity. Whether the two issued from the same crater
it is impossible to say, as the sources of both were far
away within the heart of the unapproachable desert, and
even the extent of the lava flow can only be measured
from the spot where it entered the inhabited districts.
The stream which flowed down Skapta is calculated to be
about fifty miles in length by twelve or fifteen at its
greatest breadth; that which rolled down the Hverfisfliot,
at forty miles in length by seven in breadth. Where it
was imprisoned, between the high banks of Skapta, the
lava is five or six hundred feet thick; but as soon as
it spread out into the plain its depth never exceeded
one hundred feet. The eruption of sand, ashes, pumice,
and lava, continued till the end of August, when the
Plutonic drama concluded with a violent earthquake.
For a whole year a canopy of cinder-laden cloud hung over
the island. Sand and ashes irretrievably overwhelmed
thousands of acres of fertile pasturage. The Faroe islands,
the Shetlands, and the Orkneys were deluged with volcanic
dust, which perceptibly contaminated even the pure skies
of England and Holland. Mephitic vapours tainted the
atmosphere of the entire island; - even the grass, which
no cinder rain had stifled, completely withered up; the
fish perished in the poisoned sea. A murrain broke out
among the cattle, and a disease resembling scurvy attacked
the inhabitants themselves. Stephenson has calculated
that 9,000 men, 28,000 horses, 11,000 cattle, 190,000
sheep, died from the effects of this one eruption. The
most moderate calculation puts the number of human deaths
at upwards of 1,300; and of cattle, etc. at about 156,000.
The whole of this century had proved most fatal to the
unfortunate people of Iceland. At its commencement smallpox
destroyed more than 16,000 persons; nearly 20,000 more
perished by a famine consequent on a succession of
inclement seasons; while from time to time the southern
coasts were considerably depopulated by the incursions
of English and even Algerine pirates.
