highest mountains. Whirlpools too, are 
numerous in these seas, and extremely 
dangerous; that near the island of Su~ 
deroe is the most noted. It is occasion¬ 
ed by a crater, sixty-one fathoms in 
depth in the centre, and from fifty to 
fifty-five on the sides. The water forms 
four fierce circumgyrations. The point 
they begin at is on the side of a large 
bason, where commences a range of rocks 
running spirally, and terminating at the 
verge of the crater. This range is ex¬

from the depth of twelve to eight fathoms 
only. It forms four equidistant wreaths, 
with a channel from thirty-five to twenty 
fathoms in depth between each. On the
