20 Rocks of Noyang.

 confusion, and to connect the terms I here use with those 

 which I made use of in former papers, I shall, where a 

 difference exists, note the synonym in a footnote. 



II. — Physical Geography and Geology of the District. 



The tract of country which I have mapped takes in the 

 valley of the Tambo River for three miles above and two 

 miles below the crossing at Noyang.f To the east it 

 includes the slopes of Mount Elizabeth Range, and to the west 

 those falling from the watersheds between the Tambo River, 

 Shady Creek, and the Haunted Stream. Mount Elizabeth 

 is the culminating point of a great and rugged mass of 

 mountains which fill in the fork between the Tambo and 

 Tambarra Rivers to the extent of about one hundred square 

 miles. This mountain rises to near 3000 feet above sea-level. 

 At its northern extremity it descends steeply into a com- 

 paratively low-lying basin, worn out of the metamorphic 

 schists and the intrusive rocks. Its steep and rugged ridges 

 fall to the west into Navigation Creek, and to the east into 

 a tributary of the Tambarra River ; to the south the moun- 

 tain separates into a number of great spurs covered almost 

 wholly with nearly impenetrable scrubs, the haunts of a few 

 wild cattle, and almost untrodden by the foot of man. 



The part which I have examined and mapped forms but 

 about one-fourth of the one hundred square miles covered by 

 this mountain and its spurs ; but, having seen its northern, 

 eastern, and some parts of its southern sides, I think that 

 my examination gives a fair sample of the whole. 



The Mount Elizabeth chain stands in the contact of three 

 great formations. To the north it is bordered by the extreme 

 outliers of the regional schists ; to the west there is the great 

 recurring series of lower palaeozoic slates and sandstones, with" 

 quartz veins in which are most of the gold workings of 

 Gippsland; to the east is the extensive tract of country 

 occupied by the various intrusive rocks of the Buchan and

f I am under great obligation to the kindness of Mr. A. Black, the 

 Assistant Surveyor-General, and to Mr. W. H. Gregson, the Land Officer at 

 Bairnsdale, for supplying me with tracings of official surveys of much of the 

 Noyang locality. The remainder I have filled in from rough surveys made 

 during the examination of the rock formations.
