Some where in Australia is a region, described by Mark Twain in 
Following The Equator, "The train was now exploring a beautiful hill 
country, and went twisting in and out through lovely little green valleys."

I'm trying to determine just where this might be. One cannot count on 
the narrative being chronological but it does appear that he traveled 
through this region on the train ride from Melbourne to Adelaide or from 
Adelaide to Horsham.
