The basaltic formation before mentioned, is thus described. 
“ Upon entering the harbour it has something the appear- 
ance of a fortification, The upper portion consists of a mass 
of amorphous basalt, fifty feet thick, 990 feet long, and 210 
feet wide, in its broadest part, which is in the centre. This 
mass is supported by an aggregation of basaltic columns, tho 
greatest height of which, is 25 feet. The smallest periphery 
toany one of these is two feet, and largest seven feet six 
inches. The position of these columns is vertical or nearly 
$0, (notany were observed inclincd to the horizon, bent or 
curved,) and in close contact one with the other. They are 
jointed at every foot or one foot six inches. They vary in 
the number of sides. Capt. Campbell saw them of five, six, 
seven, and eight sides ; one he measured was an irregular 
pentagon of 6 feet 6 inches, in periphery; another he 
brought home has eight sides (the smallest may perhaps be 
esteemed only a truncation,) and itis remarkable for pose 
sessing the process described by MacCulloch. (pl. 5.) 
The base of these pillars is 180 feet above the water ; from 
the former in mostplaces the ground slopes off at an angle of 
45° to meet the latter, The method adopted, unaided by 
the use of instruments, to ascertain the height of this slope, 
should be generally remembered. IJlaving taken a boat-hook 
which he found to be 15 feet 6 inches long, Capt. Campbell 
fixed a cross piece, about six fect in length, at right angles, 
to oneend ; then forcing the other, or pointed extremity, 
into the ground, at the waters edge, he plumb’d the boat hook 
to ascertain that it was upright. He then ascended the bill 
until his eye was in the prolongation of the cross piece, when
