present communication. I regret that I could not command leisure 
to examine any of these hills, excepting such as are situated close to 
the river, on the borders of which several of the lateral ranges 
terminate, and form beautiful projecting points of land. One of 
these terminates at the village of Sicligully, by a low mount com- 
posed of a crumbling rock of a dark colour. 
At the village of Pointy, or Pierpointy, the rock was of several 
varieties, composing large boulders about two feet in diameter, and 
heaped together on the top of a low hillock, the greater part of 
which they appeared to form. At the waters edge, I observed the 
same sort of rock disposed vertically, and over that a softer sandy 
stone, which seemed to be undergoing decomposition. 
At Vidasrong, or Dewal-point, which was the next spot in the 
course of the river that presented any objects for geological investi- 
gation, I found masses of rock lying on the strand, some rounded, 
and others of an irregular outline. They are of a compound 
nature, granite with hornblende, and conglomerates of quartz and 
mica with calcareous cement. The rock of the adjoining mount 
resembled that of Sicligully and Pointy. The base of the mount is 
composed of a breccia of quartz and limestone, and the upper two- 
thirds of sandstone. No regular strata are observed in these rocks, 
although something like a horizontal arrangement of the breccias 
appears at one or two points. The sandstone is placed in projecting 
masses over the others, but does not exhibit any stratification. 
Opposite to the village of Colgong, three small rocky islands rise 
out of the stream, about one fourth of its breadth from the right 
bank. The appearance of these is highly picturesque, presenting 
huge blocks of bare rock, surmounted by trees and shrubs, that 
give a variety and liveliness to the scene. The rocks exhibit no 
stratification, but are thrown together in immense masses, vStanding
