which seems to have covered the opening
to the abyss, as from the fissures around
its base issued a cold and vehement cur-

small pools of water, one of which was
hot and corrosively bitter, a second ex-
tremely salt, while the insipidity of the
third he compares to chicken broth
without salt; it was of a high degree of

a second girts 100 feet, and is 17 high.
