- GEOLOGY OF NORTH GIPPSLAND, VICTORIA. _ 35 
from the margins of the Gippsland lakes far up the river-valleys, 
extending round the margins of the lakes from river to river and up 
the rivers to the foot of the hills. The lowest terraces are in some 
places not more than a few feet above the river-level ; the highest 
terraces may merge into the sandy ridges, and are edged in places 
by the high-level river-gravels. It seems to me not unreasonable 
to refer this Terrace Epoch of Gippsland to the Pleistocene period. 
Succeeding these terraces, and but little elevated above sea-level, 
we find the alluvial flats of the rivers and the swamps and morasses 
bordering the lakes, and, as at Ewing’s Marsh, lying in the hollows 
between an older coast-line and the sand dunes forming the present 
shore-line, 
Nowhere in Gippsland have I been able to detect any appear- 
ances which I could in any way refer to a Glacial period analogous 
to that of the northern hemisphere. I have nowhere met with 
grooved or scratched rocks, erratic boulders, moraines, or any traces 
of ice-action ; and I think that had such existed they would have 
been met with ere this. Mr. Selwyn has, I believe, already noted this. 
The only features of the country which I think could in any way 
suggest glacial conditions are the apparently ancient lake-basins uear 
Omeo. Most of these have now been drained and their beds deeply 
cut into by the streams. The sequence of the various gold-drifts 
has suggested to me that some of the workings were the beds of 
lakes during the Deep-Lead epoch. At Omeo one lake-basin still 
retains some water during and after wet seasons (Lake Omeo), and 
one other isa swamp. ‘The bed of a third is now worked for gold, 
at the Dry Hill, Omeo. A slight alteration in the general level of 
the country would have sufficed to drain these lakes; and I think 
that the succession of several old stream-beds, the traces of which 
as auriferous leads are seen at increasing heights above Livingstone 
Creek, suggest an equal succession of periods of elevation of the land 
and of repose. 
(k) Voleanic.—I believe that all the rocks to be classed under - 
this head belong to the “‘ Newer Volcanic.” They consist of exten- 
sive flows of vesicular or compact dolerites and basalts. Three of 
the large outflows, known as the Wonangatta, the Dargo, and the Co- 
bungra High Plains, are situated at about 5000 feet above the sea- 
level and immediately adjoining the Great Dividing Range. That 
of Nunnyong is only separated from it by the valley of the Tambo - 
River; that of the Gelantipy and Black-Mountain tableland extends 
within fifteen miles of the Central Chain, and is situated on the line 
of high land connecting it with the Coast Range. 
Smaller patches are found on the Buchan River to the west and 
on the Snowy River and near Tubbut to the east of Gelantipy. 
Independently of the great outflows of the Bogong Mountains 
which I have spoken of (Cobungra High Plains &c.), there are some 
minor tracts on the Morass Creek, the Gibbo River, and Wambat 
Creek, all on the northern side of the watershed. 
The larger areas named above are found capping the summits of 
the mountains, and also, in places, as flows, partially tilling the valleys,
