338 GEOLOGICAL NOTES — MACDONALD. 
sheltered from the prevalent south-west winds,a section that would 
reveal the internal arrangements of this remarkable formation. 
Nor was I disappointed, for while plodding along the landwash in 
company with the south side patrol, at a slight turn in the 
coast, we came suddenly upon a beautiful escarpment some 80 
feet high and reaching inland about 500 feet. 
The late southeast gales had undermined the embankment at 
this place causing a downfall, and thereby had produced a fresh 
exposure of the sand cliff. 
The section of this exposure is as follows :— 
1. A strata of dark ferruginoussand........ 2 feet. 
2. Dark mottled Ferruginous, Siliceous and 
Garnetiferous ‘sand 420% Jib eee oer 50 feet. 
3. Garnetiferous and Siliceous only........ 200 
4, Siliceous sand, light buff colour, with few

On comparison with another exposure seen subsequently, I con- 
sidered this as a typical section of the whole formation of this 
Island. 
Here my friend, the patrol, kindly offered to take me to @ 
place on the south side of the lake where he informed me there 
was an exposure of jet black sand. Thither we turned our steps 
when a recall from our steamer somewhat abruptly terminated 
our expedition in that direction. A sudden shift of wind and a 
fast rising sea necessitated our presence aboard, and in a few 
hours we were heading towards the coast in the teeth of a north- 
wester. 
CAPE ROSIER. 
From Grand Greve to the summit west of Cape Bon Ami the 
road tends north-eastward across the Gaspe limestones, which 
are here obscured by drift. 
The summit is of grey calcareous shale. From this point the 
scenery is grand and imposing. 
A few feet from the right of the road the precipice is perpen- 
dicular about 700 feet. On the left is an escarpment of upwards: 
of 1200 feet, in many places overhanging the tide.
