peesident’s addeess — SECTION c. 
South Austealia. — ■( [Ji .) Hallett’s Cove, near Adelaide. Lat. 
85° & S., long. 138° 30' E. Glacial beds well stratified, and even finely 
laminated, with strongly striated boulders and erratics, the largest over 
eight tons in weight; ground mass, composed largely of local rocks 
floured down or pulverised, and containing abundant intensely worn 
sand grains like those of sea sand. Thickness at least 100 feet. Beds 
rest on a glaciated pavement of Pre-Cambrian rock, on which the 
strife and furrows are exquisitely preserved. Trend of furrows nearly 
north and south, changing in places to S.E. and N.W. Some of the 
large granite erratics have probably come about seventy miles from 
the south. Their cany, and the glaciation of the pavement, show 
that the ice came from the south. The glacial beds are capped by 
marine Miocene strata, showing evidence of erosion along the 
junction line. In places these glacial beds resemble lithologically 
those of Bacchus Marsh, and are probably to be correlated with them. 
It is, of course, possible that they may belong to any age intermediate 
between that of Miocene and Carboniferous. The beds extend to over 
100 feet above sea-level and descend below the level of low tide. 
(i.) Gorge of the Torrens, near Adelaide. Lat. 34° 45' S., long, 
138° 50' E. 
(j.) Curramulka, Yorke’s Peninsula. Lat. 34° 40' S., Jong. 
137° 40' E. Glaciated pavement of Pre-Cambrian or Cambrian rock, 
the grooves running north and south. Boulders of granite, possibly 
erratics, also present. This glaciation is obviously to be correlated 
with that of Hallett’s Cove, on the opposite side of St. Vincent’s Gulf. 
(A) Valley of the Inman Elver, near Port Victor. A smooth 
striated and grooved rock surface, with boukler-beds. Direction of 
grooves, east and west. Their stoss-seite not yet determined. Height 
above sea inconsiderable. 
Hew South Wales. — (7.) Marangaroo. Marine Permo-Car- 
boniferous conglomerate, with large blocks of rock, possibly erratics, 
the largest about 4 feet in diameter. Lat. 33° 17' S., long. 150° 10' E, 
Height above sea, 2,700 to 3,100 feet. 
(m.) Maitland, Hunter River Valley. Lat. 32° 45' S., long. 
151° 35' E. Erratics of granite and Devonian quartzites and grits, the 
Devonian rocks having travelled, probably from parent rock, about sixty 
miles to the south-west, from the neighbourhood of Wallerawang or 
Bathurst. Largest erratics, about 5 feet in diameter. Some show faint 
stride and slight appearance of faceting, but no markings which could 
be described as undoubtedly glacial have as yet been observed. They 
occur in the Permo-Carboniferous strata of both the TJ pper Marine 
Series and the Lower Marine Series, but chiefly in the Upper Marine, 
these two horizons being separated from one another by the Greta 
Coal Measures. At present they extend from about 100 feet above 
sea-level to probably at least 6,000 feet below sea-level in the neigh- 
bourhood of Sydney. 
(«.) Branxton, Hunter Biver Valley. Lat. 32° 40' S., long, 
151° 20' E. Erratics similar to those of Maitland. Paint striae 
observable on some, but not of undoubted glacial origin. Greatest 
diameter, from 3 to 4 feet. Evidence very clear that the erratics were 
dropped from some height, as they have indented the rocks below 
them — in one case, at all events, to the depth of 6 inches, perhaps 
more. Height above sea, 100 to about 200 feet.
