12 GEOLOGY OF AYLESFORD—HONEYMAN. 
granite boulders are observed, with occasional amygdaloids. 
Continuing our course through fallen trees and brush to a dis- 
tance of half a mile south of Canaan Road, we observe what seems 
to be the granite in si¢u. Reaching this we find immense masses 
of granite resting on stratified rock. Several outcrops of these 
rocks appear farther to the south-east. They are gneissoid rocks 
similar to those which we observed at Nictaux, and supposed 
from analogy to be of Cambrian age. Here is a field of grain. 
On the south is seemingly impenetrable forest. In this doubt- 
less lies the extension of the granite observed to the south of 
the Canaan Road. We find and return by a cart road, on which 
are exposed frequent outcrops of the gneissoid and other meta- 
morphic bedded rock, which were not observable on our pre- 
ceding way. About a quarter of a mile from the Canaan Road 
and saw mill I reached the dyke of diorite. It seemed to be as 
wide as the dykes of Nictaux, to which I have devoted special 
attention in our Polariscopic studies. (Vzde papers, &c.) Out- 
crops of slates, &c., occur before reaching the Canaan Road. 
The arrangement of rocks from North Mountain to our extreme 
point on South Mountain is: ‘Triassic with dolerites, Post-plio- 
cene drift, recent alluvium, Silurian (Souti Mountain) with 
diorites, gneissoid and slaty rocks. Cambrian? Distance nine 
miles, 
These sections correspond generally with those of Nictaux. 
The only formation that presents peculiarity is the Pleistocene. 
I have noticed southerly transportation. I expected this, and 
even a certain amount of northerly transportation; but I was 
not prepared to find it so extensive or so much northerly. I 
regard this transportation to be the work of those agencies 
which formed the valley between North and South Mountain 
after the glaciers transported the basalts and amygdaloids and 
deposited them on the South Mountain and Atlantic coast. I 
therefore would refer this northern transportation and the 
“ boar’s back” drift, generally, to the Champlain period.
