PROCEEDINGS OF SECTION C. 



when of quartzite the surface shows a high polish, and when of 

 mudstones conspicuous grooves and strife. Some moraine debris 

 including stones that have been beneath the glacier occur here. 

 On the south side, moraine matter is very abundant and includes 

 many boulders, some occurring as blocs perclies. 



The common rocks of the morainic debris are granites, gneiss, 

 hornblende-schists and others, which do not occur in situ nearer 

 than the Gorge at Normanville, about forty -six miles to the south. 

 In all seventeen distinct varieties of rock, chiefly metamorphic, 

 and foreign to the immediate neighbourhood, have been collected 

 along the path of the glacier. 



The proximity of the Miocene escarpment suggests the possibility 

 of the Pre-Miocene age of the glacier. The Miocene formation, 

 throughout its whole length on this part of the coast, has a 

 conglomerate base consisting of well rounded pebbles of limestone 

 and quartzite, and flat pebbles of slaty rock, but none other than 

 local material has been yet observed, though diligently searched 

 for. It is highly probable that the glacier cut its way through 

 the incoherent Miocene formation, and that some of the Miocene 

 shingle furnished some portion of the moraine debris. 



Some measure of the antiquity of the glacier is further afibrded 

 by the amount of marine erosion that has subsequently taken 

 place. Assuming that the glacier was in an alignment with the 

 two headlands of Hallett's Cove, then a length of three-fourths of 

 a mile by a breadth of one and a-half furlongs, and a thickness of 

 forty feet has been removed since the glacier ceased to exist. 



I exhibit the following specimens and photographs illustrating 

 glaciation at this locality : — 



1. Slab of quartzite having a highly polished surface and 



faintly striated. 



2. Chip of mudstone, having a smooth surface, strongly striated 



and grooved, taken from the site represented in the 

 photogi-aph No. 5. 



3. Ice-worn pebble, polished and striated on its upper and lower 



faces, found partly embedded in soil resting on glaciated 

 surface. 



4. A small subangular pebble of granite with one smooth face. 

 In addition to the photographs presenting general views of the 



locality, I particularly draw attention to : — 



5. Showing ice-worn face, whence specimen No. 2 was taken. 



This is the original discovery ; and the area of exposed, 

 smooth, and striated surface is seven yards long and two 

 yards broad. 



6. A nearly vertical face of ice-worn surface, indicating a 



sudden depression in the otherwise plain surface of the 

 glacier path. 



7. A large boulder of felsitic-quartzose sandstone.
