-and Cape Patterson, receives the River Tarwin, of which the 
eastern branches head from the Hoddle Range, and the northern 
from the Strzlecki Range, both portions of the Southern Spur. 
The Powlett River, entering the sea between Capo Patterson 
and Western Port, heads from a western offshoot of the .Strzlecki 
Range, which extends down to Griffiths Point, and forms the 
•southern water-shed line of the streams falling into Western Port 
Bay. In the drainage-area of Western Port Bay, the principal 
streams are the Bass and the Lang Lang, rising in the Strzlecki 
Range, and the Tarago, formerly Tanveeu, with its affluent the 
Buncep, heading from a rango which branches south-westerly 
from the Southern Spur, and forms the divide between Western 
Port and Port Phillip. For several miles the Tarago skirts the 
western slope of the Southern Spur at Neerim, and on leaving it 
receives Brandy Creek, heading from the low “ saddle 33 of the 
Southern Spur near Drouin. From another portion of this 
u saddle”* small streams flow westward into the Lang Lang. 
All waters oastward of the “ saddle ” flow into the Moe, and 
belong to the Gippsland drainage system. 
The Port Phillip Bay drainage-area is a very extensive one. Its 
principal river is the Yarra, whoso extreme sources are near the 
bifurcation of the Cordillera at St. Clair. The main northern 
tributaries of the Yarra — the Saltwater or Maribyrnong River, 
the Plenty, and the Watts — rise in the Main Divide; while of the 
southern affluents some head from the Southern Spur, and others 
from the branch range therefrom which divides the waters of 
Western Port from those of Port Phillip. From this range, por- 
tion of which is known as the Daudenong Range, several minor 
creeks descend to the eastern shore of Port Phillip. The Werribee 
rises in the Main Divide, and enters Port Phillip midway between 
Melbourne and Geelong. The Barwon River enters the sea 
through Lake Connowarre, a little to the west of Port Phillip 
Heads, and takes its rise at Mount Sabine, the culminating point 
of the Otway Ranges. The Leigh or Yarrowee and the Moora- 
bool, both northern affluents of the Barwon, have their sources in 
the Main Divide. 
In the Cape Otway Ranges, a number of crocks and rivers head 
from the Mount Sabine Range. The principal of these are — the 
Barrum, running into the sea immediately west of Apollo Bay; 
the Aire, 5 miles north-west from Cape Otway; and theGelli- 
brand, which licnds from Mount Sabine, and, draining the northern 
portion of the ranges, joins the sea a few miles north-west from 
Moonlight Head. 
Curdie’s River intersects the low-lying western portion of the 
Cape Otway district, and its mouth is about midway between 
the Gellibrand and Warrnambool. The Hopkins, which drains a 
wide area, has its outlet at Warrnambool, and its sources in a
