340 GLACIAL GEOLOGY OF CAPE BRETON—HONEYMAN. 
constitute the island, and give it direction, were doubtless raised — 
above the waters from the earliest periods, furnishing material 
for the subsequent Formations, Carboniferous and Post-Pliocene 
as well as Recent. Entering upon the Strath we find Archean 
boulders on all sides. We again reach the Post Office. Before the 
examination of the Highlands we had traversed the roads in all 
directions in courses sub-parallel to the mountains, from first to 
second parallel, from McIsaac’s Pond to Mabou Harbor, with S.E. 
offsetts. We shall now direct attention tothe last. A. From the 
Presbyterian Church we crossed the Moraine already described to 
Loch Ban, and collected choice specimens of Archzean boulders. 
Reaching the top of the Loch we took the road to the right. For 
seme distance boulders were absent, until we began to proceed 
southerly. Then they re-appeared in abundance. Coming to 
the extremity of the ,Lower Carboniferous mountains with 
Diorites already noticed, we observed our first outcrop of this 
Formation ; we turned off, and for the purpose of examining it, 
proceeding along the road, we observed Archean boulders in our 
way. Ascending toward the outcrop, boulders were still 
observed. We reached the outcrop. The rocks are chocolate 
coloured sandstones. They are raised to a high angle—70°— 
with a southerly dip. We collect specimens. Archzean boulders, 
large and small, are seen on the top of the outcrop. Of these 
wealso take specimens. We ascend the mountains still higher. 
Archzean boulders are seen at the summit. We take a level and 
find it corresponding with that of the summits of the Lower 
Carboniferous elevations of the Highlands already observed. 
We descend on the west side of this mountain, and come to a 
considerable outcrop of coarse L. C. conglomerate. As this is 
the first observed, we also take a specimen. | We also collected 
specimens of the Diorites on the other extremity of the range, 
e.g., of the summit rock, which we found to be of equal eleva- 
tion, with summits of the Archzean rocks of the Highlands. 
The elevation may be realized when (?) we noticed that the summit 
of this mountain is illuminated by the setting sun when all 
the surrounding mountains are in the shade, and the edges of the 
table land of the Highlands are distinctly visible from the out-
