Geology and Physical Geography : 
As the Strzlccki Range, and further south-east as the Iloddle 
Range, it forms the main water-shed of the South Gippsland and 
Western Port Ranges, and with its numerous offshoots constitutes, 
within an area lying to the south of a direct line from Western 
Port to the Gippsland Lakes, a mountainous tract whose only 
connexion with the Main Divide is the low 'ridge near Drouin, 
above referred to. 
From the Iloddle Range one spur descends to the sea at Cape 
Liptrap, while another slopes down to a low narrow isthmus 
lying between Corner Inlet on the east and Shallow Inlet on 
the west. South from this isthmus rises a rugged mountainous 
tract, consisting wholly of granite, of which the highest peak. 
Mount La Trobe, is 2,400 feet above the sea, and the terminal point 
is Wilson’s Promontory, the southernmost extremity of Australia. 
The Southern Spur separates the country lying to the south of 
the Main Divide into two great divisions, each of which contains 
a number of distinct drainage-areas. In the eastern division, 
which comprises nearly the whole of Gippsland, there are several 
independent streams, draining considerable areas between Cape 
Howo and the Snowy River. The Snowy River has its sources 
in New South Wales, but a large extent of its drainage-area lies 
in Gippsland; its western water-slied line is a range starting from 
near Mount Tambo, on the Main Divide, and extending to the 
low country west of the river mouth. 
Between the Snowy River and the outlet of the Gippsland 
Lakes is a small drainage-area, the waters of which pass to the 
sea through Lake Tyers. From that portion of the Main Divide, 
extending between Mount Tambo and St. Clair, and from the 
Southern Spur between St. Clair and the Iloddle Range, rise a 
number of rivers which irrigate the richest portions of Gippsland, 
and finally mingle their waters in the Gippsland Lakes, whence 
they reach the sea by a common outlet. The principal of these 
rivers are the La Trobe or Glengarry — the Morwell, Narracan, and 
Moe joining the La Trobe from the south and west; the Tanjil, 
the Tyers, the Thomson, and the Macalister, affluents of the La 
Trobe, from the north; the Avon, the Mitchell or Wonuongatta, 
the Nicholson, and the Tambo. Between the Gippsland Lakes and 
Wilson’s Promontory a number of minor streams empty themselves 
on the coast or into the various inlets. The Albert and the Tarra 
running into Port Albert, and the Agnes running into Corner Inlet, 
head from a range which forms the divide between their waters 
and those of the Morwell, and is an eastern offshoot from the 
Hoddle Range. The Franklin, the Beunison, and Stockyard Creek 
head from the Iloddle Range, and flow into Corner Inlet. 
In the main western division, that lying to the south of the 
Main Divide and to the west of the Southern Spur, are a number 
of distinct drainage-areas. Anderson’s Inlet, between Cape Liptrap
