508 NEW SOUTH WALES. 
Along all the cliffs near Kiama, and beyond to the southward, the 
structure of the basalt is more or less columnar, though seldom as per- 
fect in symmetry as above described. The cliff figured on page 497 
represents more nearly the ordinary character. The following sketch 
gives another view of the basalt, and also exhibits its superposition 
upon the sandstone. 
In the same cliff here figured, there is a fine exhibition of columns, 
and although inferior in extent to the place just described, the curvatures 
they present give great interest to the scene. These curved columns 
radiate from either side of a bank of basaltic conglomerate, which is 
twenty to twenty-four feet wide. Immediately adjoining the bank, the 
basalt is massive, with no traces of a columnar structure. Beyond 
this, as shown in the sketch here given, the columns become at once 
perfect, being scarcely less regular below at their first appearance 
than above at their extremities. They are at first horizontal, and 
after extending thus a few feet, they gradually curve upward, and 
twenty feet distant are nearly vertical, inclining but ten degrees from 
a perpendicular. The whole curvature is not seen in an upper 
view of the columns, though apparent in a side view of the bank.
