SUPPLEMENTARY NOTES. 
DISCOVERY OF GLACIATION IN TASMANIA. 
Mr. T. B. Moore, F.R.G.S., contributed some supplementary notes 
to his paper, read at the April meeting, on ‘‘ The discovery of glaciation 
in Tasmania.” He said :—During a recent trip from Mount Lyell tothe 
extreme southern termination cf the West Coast range a few signs of 
glaciation were discovered, the most important being in the neighbour- 
hood of Mount Lyell, where the Linda Valley is covered with a layer of 
moraipal matter, and in the sidling cuttings of the horse track I picked 
up numbers of scored pebbles, It will be interesting for the Linda 
gold-mining shareholders to know that the deep ground hydraulically 
sluiced on their sections is nothing but a huge mass of morainal matter ; 
many of the large boulders and smaller accumulation of stones of a soft 
nature are beautifully scored. It yet remains to be proved whether the 
glaciers have travelled from Mounts Sedgwick or Lyell; from the 
appearance of the latter mountain in the distance, I should say their 
first start was made there—travelling down the escarpments at the head 
ef the Linda River and wearing away the soft hydra-mica schists and 
pyrites beds, which, in all probability, continue northwards from the 
Mount Lyell Co.’s property. By this erosion a quantity of auriferous 
pyrites has by degrees been brought down in the morainal mass carried 
by the ice, and has been prinzipally deposited at the Linda Co.’s land at 
a point where the gullies are confined before they widen out into the 
Linda Valley. Along the base of the eastern slopes of Mounts Owen, 
Huxley, and Jukes large moraines extend into the lower land, and 
morainal matter is scattered over the broad valley of the King River. 
After the King River breaks through the range between Mounts Huxley 
and Jukes the morainal matter extends. south to the end of the latter 
mountain. The boulder accumulations havea strike either to the south 
or south-east, showing that the ice flows have travelled in these direc- 
tions, which are similar to the principal courses in the vicinity of Lake 
Dora. The most extensive ylaciation has taken place at Mount Owen, 
where a large moraine forms a connecting ridge between that mountain 
and the Thureau Hills, The northern extremity of the Thureau Hills is 
well glaciated, as shown by the ice-worn rocks and iarge greenstone 
boulders perched high upon their slopes. Six years ago I was on the 
tops of all the mountains mentioned, and found on the summits of 
Mounts Owen and Jukes small tarus similar in character to those at 
Mounts Tyndall and Sedgwick. Yet, as far as I have observed, the 
locality of the first discovery has the best and most extensive illustrations 
of land glaciation in all its forms. On my recent trip only the summit 
of Mount Darwin was examined. Herel did not observe any distinct 
signs of ice action—the rocks are rounded, but no striz visible.
