floor of the rocky knoll. All the sides of the hills to the east from 

 Lake Dora leading down to the valley of King River, are abun- 

 dantly planed, scored, striated, and polished, the latter especially 

 where the beds consist of quartzite rock ; even to the top of the 

 hills, some 300 feet above the level of the lake and on the east 

 side, these features extend, striations and polished surfaces 

 occurring to the very crest of the hills. By means of the striie 

 it is easy to see the direction in which the ice mass moved, for 

 the great glaciers, which at Lake Dora must have been at least 

 400 or 500 feet thick, moved continually outwards from wheie 

 the accumulation of ice was greatest. Studded as this ice was with 

 small and great angular blocks of conglomerate, etc., it resembled 

 a huge rasp, which, with irresistible force, filed down, rounded off, 

 planed and scored the surfaces they came in contact with, and 

 also registered in a most durable manner the course in which 

 they were travelling. About Lake Dora the striee point in many 

 different directions, and it appears as though over this tract there 

 must have been a very thick covering, the pressure of the great 

 mass above compelling the ice to travel in different directions, 

 even up the sides of hills, for the hills on the east side of Lake 

 Dora ai^e striated and scored up steep faces in the direction of 

 their crests and over their summits. 



About the best example of what such a great ice-rasp can 

 accomplish is shown at Moore's Shoulder, named after my friend, 

 Mr. T. Moore, who was my comrade and guide in this wild region. 

 At this site a great glacier throughout a vast period must have 

 been deflected around this projecting angle of rock ; the result is 

 marvellous, for the intensely hard Devonian conglomei'ate has 

 been planed, rounded, scored, and polished in a manner that 

 Ijaffles description ; the ice marks are noticeable high up the hill 

 sides. Probably at this point the ice was of great thickness, in fact 

 it appears from the scoi^ngs, etc., that a great volume of ice 

 hundreds of feet thick covered the whole of this elevated region. 



The bed-rock over this region showing such abrasions, etc., it 

 is natural to expect that the moving blocks and boulders which, set 

 in ice, formed the teeth of the rasp, should also equally bear 

 evidence of the work they did, and such is abundantly present, 

 for a large propoi tion of both great and small rocks and boulders 

 in the moraines are ground down, striated, or otherwise bear
