from which part at west end broken off. Before being broken, size 
was 52 X 36 X 20 feet, containing about 2770 tons lying on drift at 
the foot of old sea-bank, whose base is about 40 feet above seadevel. 
In this part of coast an immense number of other boulders of 
different weights up to 400 tons, some touching or lying on others. 
They are mostly on slopes facing westward {Lithograph I7o. 8,

came from N.W.

gneiss boulders lie on the shore, and on slopes facing Jura Island,
