PROCEEDINGS OF SECTION C. 453 
Range it is met with east of Gordons about four miles. The 
conglomerate forming the ‘false bottom” at Morrison’s diggings, 
and on which the tertiary drift reposes, may possibly belong to 
the conglomerate under notice, although no direct evidence of 
glaciation was observed. At Bacchus Marsh the conglomerate is 
largely developed, attaining a thickness of over 100 feet. At 
Turton’s Creek, a few miles N.N.E. of Foster (Gippsland), a 
conglomerate of well-rounded boulders and pebbles is found that 
in all probability is of glacial origin. 
These localities, so widely separated, serve to indicate the wide 
diffusion of the conglomerate. Near Nhill a boring made for 
water also pierced a conglomerate that strongly resembles what is 
proved to be of glacial origin. The known limits of the areas 
occupied by such beds will be continually enlarging as knowledge 
is gained by borings, &c., of the strata beneath the surface where 
the rocks are newer than Devonian. 
Underlying Rocks. 
Granite, Lower Silurian and Upper Silurian are the rocks on 
which the conglomerate is most commonly found to repose. It 
should also rest on the Devonian, where the two occur together ; 
but I have seen no instance of this. 
Geological Horizon. 
So far as present evidence goes, the position of the con- 
glomerate appears to be at the base of our coal-measures. Above 
it the usual sandstones and shales, with coal seams occur. At 
what height the seams are found above the conglomerate has 
still to be determined ; once settled, the conglomerate might 
prove a valuable bench-mark in further searching for seams. 
The conglomerate found in New South Wales, and described by 
Wilkinson and others as of glacial origin, may yet prove to be 
identical with the Bacchus Marsh and Wild Duck Creek con- 
glomerates. In the sandstones associated with these latter are 
found three species of Gangamopteris, as determined by M ‘Coy. 
From a personal examination of both, I can testify to the 
striking resemblance that exists between the Wild Duck Creek 
conglomerate and the widely-dispersed Dwyka conglomerate 
glacial) of South Africa. Glossopteris is found in the shales 
overlying the glacial Dwyka conglomerate of South Africa 
known as the Ecca beds. These Ecea beds comprise thick beds 
of carbonaceous shale, and, it is believed, also coal seams. Ata 
higher horizon, with an interval of several thousands of feet of 
sandstones, shales, &c., are the Stormberg coal-measures, in 
which are workable coal seams. These coal seams, in the 
character and quality of the coal, are identical with the seams
