the bank near which we stood, that it was ten or fifteen feet higher
near the centre than at the circumference. Thus somewhat of the depth was
revealed to us, and there seemed something peculiarly awful to me in the
fierce glowing red heat of the shores themselves, which never cooled with
exposure to the air and light.

Thus acted the first of the two lakes. But when, favored by a strong
breeze, we ventured farther, to the side of the furthermost one, a still
more terrible spectacle greeted us. The mass in this lake was in yet more
violent agitation; but it spent its fury upon the precipitous southern
bank, against which it dashed with a vehemence equal to a heavy surf
breaking against cliffs. It had undermined this lava cliff, and for a
space of perhaps one hundred and fifty feet the lava beat and surged into
glaring, red-hot, cavernous depths, and was repelled with a dull, heavy
roar, not exactly like the boom of breakers, because the lava is so much
heavier than water, but with a voice of its own, less resonant, and, as we
who listened thought, full of even more deadly fury.

It seems a little absurd to couple the word "terrible" with any action of
mere inanimate matter, from which, after all, we stood in no very evident
peril. Yet "terrible" is the only word for it. Grand it was not, because
in all its action and voice it seemed infernal. Though its movement is
slow and deliberate, it would scarcely occur to you to call either the
constant impulse from one side toward the other, or the vehement and vast
bulging of the lava wave as it explodes its thin crust or dashes a fiery
mass against the cliff, majestic, for devilish seems a better word.

Meantime, though we were favored with a cool and strong breeze, bearing
the sulphurous stench of the burning lake away from us, the heat of the
lava on which we stood, at least eighty feet above the pit, was so great
