nearly vertical. This of course could be caused by moving ice, 

 l>y supposing the valley to be filled with a glacier. On examining 

 the specimens by slicing them for the microscope, I found that 

 the polish was due to a thin coating of silica. Now a glacier 

 may smooth a rock and polish it, but certainl}^ not coat it with 

 .silica. The explanation is that the point at which I collected my 

 specimen is close to the boundary of an intrusive granite. The slate 

 is much faulted, broken, and contorted, and the specimen referred 

 to is part of a slickenside formed at the time of the intrusion of 

 the granite. 



So far I have not alluded to the evidences of glacial action in 

 recent times that have been described as occurring to the South 

 of Mt. Kosciusko and for the most part within Victorian borders. 

 Many of the descriptions published are circumstantial in every 

 way and cannot be lightly put aside. As I have not been over 

 the ground I cannot offer any criticisms from my own knowledge. 

 It seems to me, however, that in most of the instances quoted the 

 characters referred to glacial action could have been as well 

 attributed to other causes. In a word, if overwhelming evidence 

 was forthcoming as to the glaciers described by Dr. Lendenfeld 

 having existed in fact, then features that could have been pro- 

 duced in another way might safely be attributed to glacial action. 

 The instances cited seem to me something in the nature of collateral 

 evidence depending entirely for its value on the fact of a glacial 

 period. Mr. R. M. Johnston* has summarised the papers referred 

 to in a manner which leaves no doubt of the great weight of 

 evidence that has gradually accumulated in favour of recent 

 glacial action. I refer to this evidence merely to point out that 

 it cannot be ignored, and to emphasize the fact that this paper 

 deals only with Mt. Kosciusko and the country immediately 

 round : a tract that may be defined as embraced in the map 

 published herewith as well as that published by Mr. R. Helms, f 



My conclusions may be summed up as follows : — I have been 

 over the same ground as Dr. Lendenfeld and Mr. Helms. I
