east. As far as I have been able to discover, however, the 

 geological features of the greater portion of the district have not 

 yet been described. In his "Southern Gold Fields," p. 125, the 

 late Rev. W. B. Clarke, M.A., F.G.S., etc., briefly speaks of the 

 country between the Indi and the Muniong Range as granite 

 and slate with dykes of porphyry from the subjacent granite, and 

 near the summit the slate transmuted into an imperfect gneiss. 

 The map published with the volume does not delineate the 

 features of the country on the west of the Muniong Range and 

 as the names of localities have since been changed it is exceed- 

 ingly difficult to trace his course, but judging by the description 

 given on p. 121, he appears to have followed the Snowy Creek 

 up to the point opposite Leatherbarrel ford which is probably 

 identical with his Woolayian, then along the present track to 

 Burramungee (Monaro Gap ?). Tangaruccan, spoken of on p. 

 138, may be the place now known as Tom Groggin or more 

 commonly Groggin. and Piaderra also somewhere in the same 

 locality. As regards that portion along the Groggin track the 

 boundaries shown on the geological map will require a little 

 variation since, with the exception of one limited portion, the 

 whole area consists of various kinds of granite. In the following 

 paper I shall endeavour to give a brief outline of the general 

 geological features on this and the Kosciusko track as gathered 

 during a hurried journey along it. Time forbade a careful 

 examination of any particular locality, so the observations were 

 necessarily general and there are several portions, more especially 

 near the " Gehi Wall," that are highly interesting and worth 

 careful study. 



The Victorian township of Towong on the Murray River lies 

 at the northern termination of the Mount Elliot Range consisting 

 of granite and mica schist with highly auriferous quartz veins and 

 reefs. A flat about a mile and a half wide separates this range 

 from those in New South Wales and is a rich alluvium several 

 feet deep with a sub-stratum of sand and gravel containing 

 pebbles of granite, slates, mica schists, quartz, quartzite, etc. 

 For some eight miles the track follows the valley of the Little 

 Murray, then turns to the east to cross a low range forming the 

 Khancoban — Black Creek Divide. The rock is a tine-grained, 

 pinkish-grey granite with much orthoclase and quartz, but little
