tion, must be enormous on mountain peaks like Mt. Kosciusko. 

 Many of the great packs of loose rock material have no doubt 

 been formed by selective process, the smaller stones being carried 

 away where heavier masses remain. I have noticed immense 

 blocks undoubtedly carried a short way down some valleys — ■ 

 blocks which one could hardly suppose were carried by running 

 water. I can see no reason, however, for assuming that ice was the 

 transporting agent. By a continuous undermining (by running 

 water) of the softer materials on which they rested, they could 

 easily have been moved into their present positions. 



Some of the granite rocks to the south and west of Lake 

 Merewether have a decidedly rounded and smoothed appearance, 

 but not more pronounced, I should say, than that familiar to every 

 geologist in the granite districts of New England and even in the 

 neighbourhood of Bathurst and Cowra. 



I repeat that it may be necessary to assume the existence of. 

 thick sheets of ice to explain some of the features noted, and we 

 may even utilise valleys filled with snow, over the frozen surfaces 

 of which boulders may have slid; but assuredly there is no feature 

 in. Evidence Valley that requires moving ice to explain it. 



Dr. Lendenfeld and Mr. Helms have assumed throughout that 



there is above their supposed glaciers a gathering ground where 



snow could accumulate and consolidate into ice, and so form a 



f -eding ground for the glaciers. A few hundred yards from the 



great glacier, supposed by Mr. Helms to have come down from 



Mt. Twynam, we have the very summit of a sharp divide, with 



a rapid fall away on the other side. We have, in fact, a glacier 



without a gathering ground, a condition of things not easy to 



understand. Dr. Lendenfeld in like manner fills the Wilkinson 



Valley with a glacier. The learned doctor from his experience 



very well knew that a glacier must have a gathering ground. 



Following up the Wilkinson Valley from the point where Dr. 



Lendenfeld makes his glacier do most of its work we come, in 



about half a mile, to the summit of the divide, from which point 



another valley dips away on the opposite side. It is reasonable 



to ask : where were the snow-fields and the gathering ground for 



the clacier of the Wilkinson Valley 1 Dr. Lendenfeld replies by
