CONCLUDING REMARKS. 
because the loose sands and low sandy ridges 
crowned with scrub, described by Captain Frome, 
were very similar to what I met with near Lake 
Torrens in the west side, before I reached its basin. 
After the Northern Expedition had been compelled 
to return south, (being unable to cross Lake Torrens,) 
the peninsula of Port Lincoln was examined, and 
traversed completely round, in all the three sides of 
the triangle formed by its east and west coasts, and

overland from Mount Arden was forced through the 
scrub for a dray ; but the country travelled through

has since made an attempt to take over a few head of 
cattle by this route, but was unable to accomplish 
it, and miserably perished with his whole party from 
want of water.* 
On the northern side of the triangle I have al- 
luded to, or on the line between Mount Arden and 
Streaky Bay, a singularly high and barren range, 
named the Gawler Range after His Excellency the 
Governor, was found consisting of porphoritic gra- 
nite, extending nearly all the way across, and then 
stretching out to the north-west in lofty rugged out-

and sterile character of the country in which it was 
situated, as well as of the range itself, which consisted
