254 NOTES ON GLACIAL ACTION—-HONEYMAN. 
1. Three Fathom Harbour, on the Atlantic Coast. 
2. Preston. 
3. Goff’s, on Old Guysboro’ Road, or rather £ mile beyond. 
4. Enfield, on the Intercolonial Railway. Trans. 1. N.S. 
E. Connecting these points we have a line which may be 
regarded as the eastern boundary of Amygdaloidal drift distri- 
bution, while A line may be regarded as the western houndary. 
We may thus have the approximate form and width of the 
moraine of which the accumulations formed a part. The width 
from N. W. Arm to Three Fathom Harbour is about 16 miles, 
from Navy Island to Preston it is 9 miles. Entield is 23 miles 
nearer Blomidon and Partridve Island than Three Fathom Har- 
bour. 
Col. Akers directed my attentiun to a seooped out ledge on 
the site of the Old Chain Battery at the North-West Arm. Ihave 
pointed out the voche moutonnee, containing what is supposed 
to be a relic of the Chain Battery, with a scooping of argillites, 
on the entrance to the road that leads to the Prince of Wales 
Tower. | 
These indicate the scooping power of the ageney which seems at. 
least to have aided in the formation of the North-West Arm. At 
the top of the Arm, on its western side, I also shewed another 
scooping, when I was engaged making observations on the glacia- 
tion of the Halifax Peninsula. 
Breccia. 
It is upwards of 20 years since my attention was directed to 
a formation of this kind overlying the tilted argillites. This 
conglomerate was observed at the east side of the North-West 
Arm, at its top, and also on the west side of the Harbour between 
Richmond and H. M. Dockyard. Considering this to be like 
other conglomerates, formed by the action of sea agency, I was 
disposed to regard our conglomerate as the remains of an ancient 
formation, e. g., Carboniferous. Good examples of this may be 
seen at the west side of the North Street I. C. R. Station and 
opposite the late Observatory Hill, and at the north-end of Dutch 
Village. I am persuaded that the rock is a glacial debris
