Glacial Action in Australasia. — Hitchcock. 253 
and says that the sources of the large granite boulders have not 
yet been discovered. Very likely they have been concealed by 
later Mesozoic or Cenozoic deposits of marine character. 
Mr. E. J. Dunn, in a report upon the Bendigo gold field for 
1892 (reprinted in 1896), has the following about one locality 
of these glacial conglomerates: 
On the west side of Kangaroo gully, and opposite Opossum gully, 
an outlier, a few chains in length and from one to two chains wide, oi 
conglomerate that is referable to the same age as the Wild Duck Creek 
conglomerate occurs; it does not appear to be of any great depth, and 
in age may be of Permian or later date. In a more or less clayey 
matrix, in part rudely stratified, and in indurated fine gravel, are well 
rounded pebbles of quartzite, derived from Devonian conglomerate, 
hard grey sandstone in angular blocks, small fragments of schist, etc., 
the pebbles and fragments with the longer axes as frequently nearly 
vertical as horizontal. Veins of pale yellow chalcedony occur pene- 
trating the clayey matrix; no other outlier was noticed in the vicinity 
of a similar character. The conglomerate is very distinct from, and in 
no way to be confounded with, the Tertiary conglomerates; it is the 
last vestige of what may have been a very extensive deposit. 
The eailiest reference to ice action in Mctoria was in 1866, 
when Sir R. Daintree called attention to the probability of a 
marine glaciation (icebergs) to account for the formation of 
conglomerates near Darley, at Bacchus Marsh, Wild Duck 
river, and other places, near the close of the Permo-Carbon- 
iferous. This view was confirmed shortly afterwards by A. R. 
C. Selwyn, who was later the Dominion Geologist for Canada. 
R. D. Oldham agreed to these same conclusions twenty year^ 
later, speaking of them as being due to "moraine glacial trans- 
port," stating that they are the equivalents of the similarly- 
formed Talchir beds of India, and affirming that they "contain 
al>un(lant evidence of the action of floating ice" (Records, 
Geol. Survey of India, vol. XIX). Oldham also correlated 
these beds with others occurring in the X'ewcastle de])0sith, 
iNew South Wales. 
six. E. J. Dunn presented the subject of these conglom- 
erates before the Australasian Association for the Advancement 
of .Science in 1890. He stated that this conglomerate is spread 
over a wide area along the dividing range, as at I>acchus 
Marsh, Wooragee, Wahgungah, Rutherglen, The Springs. El 
Dorado, Tarrawinga, Badaginnie, Wild Duck Creek, Caris- 
■J)rook, and llic ( lardens. It is over one hundred feet tliick. The
