ArT. I—GLactIAL GEoLoGY OF CAPE BRETON*. BY THE LATE 
Rev. D. Honeyman, D.C.L., F.RS.C., &e., Provincial Geo- 
logist. 
In our walks around STRATHLORNE the abundance of boulders 
of Archzean rocks attracted attention. Fortunately recent rams 
had washed and brightened them, rendering their characters very 
obvious. A collection of them would be readily mistaken for one 
of our representative collections made in and around Halifax. 
I at once recognized a relationship. The boulders are Syenites, 
Syenitic Gneisses, Diorites and Porphyrites. The Pre-Cambrian, 
or Archzean, Mabou Highlands, extending West, N. West and 
South-West, and corresponding with the N.S. Cobequid Moun- 
tains, were suspected to be their scurce, and action similar to 
that established in Nova Scotia was suspected to be the efficient 
cause of their distribution. 
Referring to Mr. Fletcher’s Map, still in sheets, I observed on 
the margin ‘glaciation signs,’ which seemed to have a bearing on 
the distribution. Locating these I found one position at Green 
Point, near the mouth of Mabou Harbour, about a mile to the 
West of the South-westezn extremity, and another on the West 
side of Lake Ainslie, near the reputed oil region, and opposite 
McLean’s Point, vide Fletcher's Map. We now purposed to 
adopt the method of investigation which had led to such good 
results in Nova Scotia. 
Having mounted Fletcher’s Map and extended ona wall, we 
extended the courses of the glacial grooves of Green Point ina 
S. E. direction as far as Craigneish Mountains of Archzan age. 
We then drew another parallel to this, so as to include the lota- 
lity of the other glaciation at Lake Ainslie. This hypothetical
