There can be no doubt, in my opinion, that glaciers existed 
on the Western Highlands of Tasmania, descending to 
within a few hundred feet of sea-level, if noi to seatlevel 
itself. 
The greatest accumulation of moraine matter is at 2000 
feet above the sea on that coast, but last year I remarked 
numerous large hog-baczxed moraine heaps at an elevation of 
500 feet above the sea in the plains at the foot of the eastern 
slope of Mt. Darwin. These heaps are accumulations of 
stones derived from thé Silurian schists and quartzites of 
the West Coast range. I saw no icescratched stones in the 
heaps themselves, but noticed a few among the ballast of 
the North Lyell railway line. This ballast had evidently. 
been procured from the moraine heaps. ; 
The moraines occupy a large valley, part of the existing 
drainage system, and hence it may reasonably be concluded 
that the Tertiary glacier conditions continued to the close 
of the Tertiary era, or were even prolonged into Post- 
Tertiary time. i

Under the guidance of Professor. Hogg, a large number of the 
members of the Geology Section had the advantage of examining 
the Little Peppermint Bay Section at the cenelusion of the 
ice-scratched boulders were found in sit, thus entirely confirm- 
ing Professor Hogg’s views.
