As a geologist. I however, may, along with the astronomer, lay 
some claim to that privilege of ‘■l)elonging to a branch of science 
which has nothing to do with War.*' unless indeed those violent 
tremors in the region of the AFediterrancan, ascribed by ancient 
mythology to the quiverings of that hundred armed giant, Typheus. 
\vhile endeavouring to escape from his fiery prison, arc indicative 
of internal warfare in what FTamlet calls "this goodly frame the 
cartii.” may be held to distJrove the claim. 
After some deliberation I have chosen to address you on a 
snl)jcct of my own particular science, rather than to wander as a 
comparative stranger into other fields. 
Coming therefore to the subject of my address, I ])urpose de- 
parting somewhat from cstal)lished custom and instead of looking 
l)ackwards. will endeavour to look into the future, and point out 
some ])rohlems of Western Australian geology which provide 
abundant opportunities for collective and individual research. 
Fig. I. 
Scarplike face of Oarling Range. 
'file southern half of Western Australia affords perhaps no 
more striking feature than the scarp-like face of what is generally 
known as the Oarling Range, and which forms the western rim 
of the Plateau of the Interior. ( b'ig. 1 ). This rim of crystalline 
rocks rises to heights about feet above the lu'oad, compara- 
tively fiat expanse known as the Coastal Plain. 
d'he boundary between this Plateau and the Coastal Plain is 
virtually constituted l)v a nearly straight or at least a gently curv- 
ing line, and forms part of a long zone in which faulting is the most 
important structural feature. What may he called offset faults.
