ground above the ancient snow line, and seeing that the 

 valleys have been worn and eroded to a greater extent at 

 much lower levels, is it not more than probable that this 

 higher eminence, the seat of prehistoric glaciers, standing, as 

 it does, near the coast line, has let loose its glaciers, which 

 have descended down the steep slopes with nothing to impede 

 their course, and have tumbled into the waters of the harbour 

 before melting ? 



A connecting ridge, with grooved summit 1,700 feet high 

 between the two mountains, divides the watershed of the 

 Clarke and Garfield Rivers. The latter stream drains the 

 north ends of the mountains, and is a tributary of the King 

 Eiver. The northern valley is at a much lower altitude (800 

 feet) and narrow, the gorges are more numerous, longer, and 

 deeper cut. The rocks are all worn smooth, and in places 

 grooved. An occasional erratic is seen, but little morainal 

 matter left in the beds of the creeks, showing that the ice has 

 travelled a considerable distance in this direction. 



The principal gorges north and south of the ridge head 

 from Mount Darwin, and the greatest waterflow at the present 

 time comes from that mountain, whose summit I stated in 

 my last year's supplementary notes has no signs of strise, the 

 rocks being rounded. 



The low lying moraine, with its glaciated stones near the 

 Craycroft Hills, conclusively proves that the ice has descended 

 to much lower levels than anticipated by Messrs. Johnston 

 and Montgomery, and the scored boulders near Farm Cove 

 indicate, if not in a general way, in some cases the glaciers 

 have reached sea level. 



It is improbable that the boulders at Farm Cove are the 

 results of icebergs in the Permo-carboniferous period, for it 

 will be observed that the scorings on the illustrative specimens 

 are well marked and clear, as if only scratched a few years 

 ago, besides the boulders lie without surface covering, and 

 their polished and scored surfaces have been exposed to all 

 atmospheric influences, and in many cases to wave action. 

 Such being the case, it is hardly possible that the ice mark- 

 ings would have remained so intact for so long a period, i.e., 

 since the Permo-carboniferous era. 



If the scored boulders had been deposited by floating ice 

 we would expect to find similar evidences in the tertiary 

 beaches, which I need hardly say have been elevated since the 

 ancient ice epoch ; this not being so clearly proves that our 

 glaciers in some cases have descended to sea level. Also the 

 non-evidence of any signs of ice action, except erosion in the 

 palaeogene-lacustrine deposits at Macquarie Harbour will give 

 a good proof as to the age of our recent land glaciation. 



Before concluding, I might mention that in. the beginning 

 of 1893, during a tour down the coast south of the harbour,
