96 THE GLACIER EPOCH OF AUSTRALASIA, 
far as I know, has left no special memoir of his extended 
observations on this subject. 
In the year 1874, in company with the late Honorable 
J. A. Scott, W. C. Piguenit, Lieut. Burgess, and two other 
persons, I spent six weeks (all of the party laden with knap- 
sacks weighing from 60 to 70 lbs.) in exploring the whole of 
the south-western region of the western highlands lying 
between the mouth of the Huon and Macquarie Harbour, 
and in making collections and observations on the geology 
and botany of this region. In the year 1879 I formed one 
of a similar party in exploring the northern region of the 
western highlands, including Gad’s Hill, Middlesex Plains, 
Vale of Belvoir, Valentine’s Peak, Mount Bischoff, head 
waters of the Mackintosh Valley, and other tributaries of the 
Pieman and Arthur. 
In the year 1887, in company with my friend, the late 
C. P. Sprent, Deputy Surveyor-General, and five others, I 
traversed, on foot, and examined the whole of the region 
lying near to the route across the island by way of the Ouse, 
Bronte, Lake St. Clair, Mount King William I, Mount 
Arrowsmith, Collingwood Valley, King River, Mount Lyell, 
Queen River, Macquarie Harbour, thence northward across 
the Hentys, Mounty Heemskirk, Corinna, Whyte and Hazle- 
wood Rivers, Magnet Range, and Mount Bischoff, to Emu 
Bay on the North-West Coast. I had the opportunity at 
this time to visit many of the lakes, including Lake Dixon, 
and to spend three days in examining more particularly the 
rock formations on Mounts Owen, Lyell, and Sedgwick. 
I had thus ample opportunities for observing the many 
evidences of former glaciation in these regions, enabling me 
to confirm the earlier observations of Mr. Gould, and also 
enabling me to record the general results of such observa- 
tions in my work on the “ Geology of Tasmania,” begun in 
the year 1884, and published in the year 1888. I only gave 
my general conclusions in this work, although my notes 
contained particulars regarding the abundant occurrence of 
moraines, roches-moutonneés, scooped tarns and lakes innu- 
merable, huge ice-born erratics, polished rock surfaces, etc., 
in many localities; notably in the Gorge descending from 
Scott’s Peak in the centre of the lofty and picturesque 
Arthur Ranges, and along the Alpha and other tributaries of 
the Craycroft and Huon River; in deep gorges descending 
from Mount Wedge towards Lake Pedder and the Serpen- 
tine ; on the neighbouring slopes of the Frankland Range ; 
in deep upper gorges and valleys of the tributaries of the 
Mackintosh River leadivg from Granite Tor and Barn Bluff; 
but particularly in the romantic valley of the Lakes Dixon 
and Undine, at the source of the Franklin, in the immediate
