344 GLACIAL GEOLOGY OF CAPE BRETON—HONEYMAN. 
to Halifax, on Friday, August 2nd, we were fortunately detained 
at the Railway Terminus, Port Mulgrave. Here we observed a 
section of heavy Drift, with Archzan boulders in abundance. 
We had sufficient time to collect a good representation of these 
for our Provincial Museum. The specimens are identical with 
those collected at Strathlorne and Mabou. Looking at Fletcher’s 
map, we find that this section of Drift lies southeast of the 
Archzean area of Cape Porcupine, and about a mile distant. We 
regard this as conclusive evidence of the glacial action Hy- 
pothesis. 
This seems to remove a difficulty in the way of introducing 
the Mastodon ohioticus into Cape Breton, in consequence of the 
intervention of the Strait of Canso. We have only to refer the 
introduction to pre-glacial times, when the Strait of Canso may 
have had no existence.
