and deep respectively. Travelling five miles in a north-west 

 direction past Phillip Island, along the present beaches the 

 grooved and scored masses are scattered over the whole of 

 that distance, and similar boulders, with the ice marks 

 obliterated, are found extending far out into the waters of 

 the harbour. Where the raised tertiary beaches have been 

 denuded and now form the present sandy beaches the 

 boulders on the land are covered from sight, but in the 

 shallows of the shore they are plainly visible. The boulders 

 rest on the lignite beds which have been denuded of their 

 original overburden, but cannot be traced below the consoli- 

 dated sand and fine clayey sedimentary cliffs. They are 

 either exposed to all atmospheric influences or embedded in a 

 recent earthy matter. On the eastern side of the point, the 

 entrance to Farm Cove, a third of the way across is blocked 

 even for navigation by small crafts by masses of boulders, 

 rising in places above high water mark, and forming resting 

 haunts for sea birds. 



Let us follow the shores of the harbour past my recent 

 explorations towards the coast to Sophia Point, or even to 

 Strahan. Here we find boulders forming long points, in 

 many places strewn over the present beaches or extending into 

 the water, which if examined probably will prove to be ice- 

 borne blocks. 



Eaised tertiary beaches enclose nearly all the mirth-eastern 

 shore of the harbom - , as it were, with a formidable wall of 

 consolidated sand and mud. Nowhere do we find boulders 

 in the consolidated mass, only on the uuconimed points, 

 heaped together on the narrow roadway at the base of the 

 precipitous sandy cliffs jutting out into the water, or opposite 

 the localities where the raised beaches have been cut out or 

 almost wholly swept away, as at Kelly's Basin and at Farm 

 Cove. On the summits of these sandy walls and all over the 

 surrounding country what I now conclude is morainal matter 

 extends to Mounts Sorell and Darwin ; for the large boulders 

 we find could not have been so shaped, rounded, or deposited 

 by any other means but ice. Travelling up to the valley 

 between Mounts Sorell and Darwin the bed rocks of the 

 creeks are worn smooth, and very little sedimentary material 

 left in their courses. The valley is open, and ranges from 

 1,000ft. to 1,300ft. above sea level, is a mile broad and two 

 and a half miles long, and has been swept clean of most of 

 the morainal matter, leaving here and there huge, rounded, 

 polished, and grooved boulders, in some instances as large as 

 those described by Mr. Dunn as the Pilgrim, Traveller's, etc., 

 in the Tyndall country. One monster measured 36ft. long, 

 24ft. broad, and 10ft. high. 



The enclosing slopes and shoulders of Mounts Sorell and 

 Darwin are all well rounded and in many places grooved, the
