PRESIDENT’S ADDRESS — SECTION C. 
91 
( 0 .) Grasstree, near Muswellbrook. Lat. 32° 20' S., long. 
150° 59' E. Erratics similar to those of Branxton and Maitland. 
Geological horizon is that of the Upper Marine Series of the Permo- 
Carboniferous System. Height above sea, about 170 to 200 feet. 
Queensland. — ( p .) Bowen River Coal Eield. Lat. 23° S., long. 
149° E. Erratics, the largest of about the capacity of 2 cubic feet, 
and mostly angular or subangular. They occur chiefly in the Marine 
Permo-Carboniferous beds of the Middle Bowen Series, and the 
horizon is probably homotaxial with that of the Upper Marine Series 
of New South Wales. 
Possible Evidences of Glaciation in Triassic Time. 
New South Wales. — (a.) Disrupted and bent masses of clay 
shale, and contemporaneously contorted bedding in the Ilawkesbury 
Series near Sydney. Lat. 33° 52' S., long. 151° 12' E. Height above sea, 
twenty to forty feet. 
(b.) Disrupted fragments of clay shale in Ilawkesbury Sandstone 
near Katoomba. Lat. 33° 45' S., long. 150° 28' E. Height above sea, 
about 3,350 feet. 
Second Glaciation of Australia and Tasmania in Pliocene or in 
Post-Pliocene Time. 
Tasmania. — (a.') Planed and grooved rock surfaces, terminal 
moraines, and erratics near Lake Dora. Lat. 41° 52' S., long. 
145° 33' E. Poches moutonnees are frequent. Direction of grooving 
very variable, chiefly towards east and south-east. Some morainic 
blocks, perhaps over 100 tons in weight, are all of local origin. Well- 
defined termiual inoraiues, 150 feet to 250 feet high, prove conclusively 
that these evidences of ice-action are due to land glaciers only. Lakes 
and tarns of glacial origin are also numerous. Height above sea-level 
ranges from 1,750 feet to 3,000 feet. Similar evidences occur a trifle 
further north at Lake Rolleston and Lake Ruby. In the same district 
Mount Tyndall is glaciated from 2,182 feet to its summit, 3,850 feet 
high ; and Mount Sedgwick, 4,000 feet high, is also glaciated to within 
a few feet of its summit. 
( b .) Talley of the Macintosh River. Lat. 41° 40' S., long. 
145° 30' E. Granite erratics at least five tons in weight. 
( 0 .) Lake Dixon. Roches moutonnees , moraines, and large 
erratics. Elevation about 2,000 feet. 
(d.) Mount Pel ion, Barn Bluff, and the head of the Eorth. 
Lat. 41° 45' S., long. 146° E. Roches moutonnees, erratics, and striated 
rock surfaces. Movement of ice, near East Mount Pelion, from north 
to south. Traces of glaciation so fresh that Mr. Montgomery thinks 
they cannot be older than Pleistocene. Moraines, erratics, and roches 
moutonnees also in same neighbourhood, near Lake Eyre. Height above 
sea of last-mentioned ranges from 2,000 to 2,792 feet. 
( 0 .) Scott's Peak, in the Arthur Ranges. Moraines, roches 
moutonn6es , and polished rock surfaces. 
Victoria. — (f) Mount Bogong District. Lat. 36° 42' S., long. 
147° 10' E. Reewa Valley. Moraines (?) at 1,000 feet above sea-level. 
( y.) Mountain Valley Creek, northern base of Mount Bogong. 
Lat. 36° 45' S., long. 147° 20' E. Large angular masses of rock, 
perhaps redistributed moraines. Height above sea, 2,000 feet.
