president’s ADDRESS — SECTION C. 
(3.) In the same paper I added to the possible evidence of ice- 
action in the Triassie-Hawkesbury series, previously described by 
Wilkinson, the prevalence of remarkable contemporaneous contorted 
bedding in the Hawkesbury Sandstones. This is illustrated in the 
woodcut on page 194 of my paper above referred to. A short time 
later I observed at Branxtou, near where Mr. Oldham obtained his 
striated pebble, a block of granite measuring 2 feet 3 inches high, by 
1 foot 3 inches wide, by at least 3 feet 3 inches long, and bedded in 
the rocks in such a way as proved that it could not have been laid 
down simply by the agency of water. It is poised on its edge, and the 
bed on which it rests shows distinct evidence of having been deeply 
indented by the erratic, as shown on the enlarged photograph now- 
exhibited, as though the mass of granite had been dropped from a 
height on to the bed, probably by the agency of floating ice, at a time 
when the bed formed part of the sea floor. 
The overlying strata show no evidence whatever of having 
partaken of the bending to which the strata immediately underlying 
the erratic have been subjected. 
In 1887 Mr. B. M. Johnston recorded the evidence of recent local 
ice-sheets and glaciers in the western highlands of Tasmania, notably 
along the deeply cut ravines of the Macintosh Biver.* * * § 
The same year Professor Tate published a further account of the 
glacial evidences at llallett’s Cove.f 
In the same publication Mr. B. M Johnston recorded his observa- 
tions regarding recent glacial phenomena in the western highlands of 
Tasmania. 
In 1887 Mr. Gr. S. Griffiths read a paper on 44 Evidences of a glacial 
epoch from Kerguelen’s Land, being comments on the 4 Challenger’ 
reports. 
In this he draws special attention to the fact that the lower 
valleys of Kerguelen Island are scraped and scratched and smoothed 
by giaciers even to below sea-level, while some of the outlying islands 
have been powerfully glaciated. (At present the snow-line on the 
south side of the island, where the above evidence was obtained, is 
between 900 feet and 1,000 feet above sea-level.) 
He also quotes the statement from the 44 Challenger” reports that 
i( small granite erratics were noted in the Pacific in lat. 8. 38°, far 
from land.” 
In 1887 Mr. James Stirling, in his paper§ on the Physiography of 
the Australian Alps, summarises thus the evidence of ice-action in 
that region : — 
44 Erratics in the Mitta Mitta and Kiewa valleys, huge blocks 
weighing many tons ; smoothed surfaces on the Cobberas Mountains 
and Mount Eogong ; moraines at the base of the latter at the 
Mountain Valley; eroded lake basins, Dry Hill ; Hermo-mugee swamp, 
Omeo Lake basin ; morainic lake, Mount Wellington ; smoothed and 
scratched surfaces on Mount Kosciusko.”

describes certain boulders met with in the beds and reefs of the
