GLACIAL COMMITTEE. . 193 
Postscript I—A discovery of considerable importance was 
made (during the meeting of the Association in Tasmania) 
by Mr. A. E. Kitson, of the Geological Survey of Victoria. 
Mr. Kitson, while on the excursion, observed ice-scratched 
boulders in coarse conglomerates along the beach between 
Burnie and Table Cape, on the North-West Coast of Tas- 
mania; and the members of the Geological Section, under 
the leadership of the Assistant Government Geologist, Mr. 
G. A. Waller, were afforded an opportunity of inspecting 
this highly interesting glacial deposit. It is extensively 
developed along the shore at intervals between Burnie and 
Table Cape, one of the best sections being at a point about 
three miles distant from Wynyard, on the north side of the 
road from Burnie to Table Cape. The boulders are mostly 
from half a foot to one foot in diameter, much rounded, 
beautifully and intensely glaciated, the finest striz being 
exquisitely preserved, as well as che deep and coarse grooves. 
The matrix in which these are imbedded is a very hard mud- 
stone, so compact that great force is needed in order to dis- 
lodge the boulders from the matrix. The glacial beds have 
a low angle of dip, and rest with strong unconformity upon 
the nearly vertical edges of the older Paleozoic rocks. 
At Table Cape the glacial beds are capped by over a 
hundred feet of marine Eocene beds, covered in turn by 
Tertiary nepheline-basanites. The section exactly recalls 
that of Hallett’s Cove, near Adelaide, in Souch Australia, 
and Point Turton, in Yorke’s Peninsula, also in South Aus 
tralia. (See Mr. Howchin’s description, given later in this re 
port.) 
There can be little doubt that the Table Cape Permo- 
Carboniferous glacial beds lie at the very base of the Permo- 
Carboniferous system, and are homotaxial with the glacial 
beds at the base of the Permo-Carboniferous system at Loch- 
invar, in New South Wales, described by Professor David.* 
It is equally probable that they are to be correlated with 
the Hallett’s Cove and Turton Point glacial beds of South 
Australia. 
The Table Cape glacial beds are clearly stratigraphically 
below the Mersey and Arthur River and Inglis River coal- 
measures, the relations being probably somewhat as shown 
on the sketch-section reproduced in part from the report 
on the coal near Arthur River by Mr. G. A. Waller, 
a Trans. Roy. Soc. N.S. Wales, 1899, Vol. xxxili., pp. 154-159,
