Our Visit Seemed In Vain, For On The Risky Verge Of This Crack We Could Only Get Momentary Glimpses Of Wallowing Fire, Glaring Lurid Through Dense Masses Of Furious Smoke Which Were Rolling Themselves Round In The Abyss As If Driven By A Hurricane.

After failing to get a better standpoint, we suffered so much from the gases, that we coasted the north,

Till we reached the south lake, one with the other on my former visit, but now separated by a solid lava barrier about three hundred feet broad, and eighty high. Here there was comparatively little smoke, and the whole mass of contained lava was ebullient and incandescent, its level marked the whole way round by a shelf or rim of molten lava, which adhered to the side, as ice often adheres to the margin of rapids, when the rest of the water is liberated and in motion. There was very little centripetal action apparent. Though the mass was violently agitated it always took a southerly direction, and dashed itself with fearful violence against some lofty, undermined cliffs which formed its southern limit. The whole region vibrated with the shock of the fiery surges. To stand there was "to snatch a fearful joy," out of a pain and terror which were unendurable. For two or three minutes we kept going to the edge, seeing the spectacle as with a flash, through half closed eyes, and going back again; but a few trials, in which throats, nostrils, and eyes were irritated to torture by the acid gases, convinced us that it was unsafe to attempt to remain by the lake, as the pain and gasping for breath which followed each inhalation, threatened serious consequences.
