GEOLOGICAL FEATURES.

Moulong Plains, a military station intermediate 
between Bathurst and Wellington Valley, lime- 
stone appears in the bed of a small clear stream, 
and with little interruption continues to some 
distance below the last-mentioned place. The 
accidental discovery of some caves at Mou- 
long Plains, led to the more critical examination 
of the whole formation, and cavities of consider- 
able size were subsequently found in various 
parts of it, but more particularly in the neigh- 
bourhood of Wellington Valley. The local in- 
terest which has of late years been taken in the 
prosecution of geological investigations, led 
many gentlemen to examine the contents of 
these caverns ; and among the most forward. 
Major Mitchell, the Suiweyor-General, must 
justly be considered, to whose indefatigable per- 
severance the scientific world is already so much 
indebted. 
The caves into which I penetrated, did not 
present anything particular to my observation ; 
they dilfered little from caves of a similar des- 
cription into which I had penetrated in Europe. 
Large masses of stalactites hung from their roofs, 
and a corresponding formation encrusted their
