FORMATIONS. 
The formations described in these notes may be stated thus: 
I. Cambrian Metamorphic, belonging to the great gold form- 
ation of Nova Scotia. 
II. Post Pliocene, or glacial drift. 
ROCKS. 
I. Cambrian Metamorphic. The rocks of this series are slates, 
which extend over the whole peninsula. 
The first exposure we notice is at the old “Lime Kiln,” 
Pleasant Street. In this we note the following points :— 
1. Lines of bedding. 
2. Slaty cleavage. 
3. Jointed structure, result of metamorphism. 
4, That the dip is to the south, and the strike approximately 
east and west. 
In the shore exposure of the bank below the old three gun 
battery we find the most interesting exposure of the series. 
Before we reach this the strata dip regularly to the south, but 
here we find the strata much disturbed, and just a little to the 
south we find the synclinal axis, with strata having northerly 
and southerly dips, the argillite strata in the middle being bent, 
the lines of strata being shown by a number of parabolic curves. 
Proceeding farther to the south we find the series dipping regu- 
larly to the north. 
LIFE OF PERIOD. 
No remains of life have been found in these rocks. On “ Black
