intensely folded or stretched out, so that a 
once continuous band of rock has been broken 
into a string of small isolated blocks. A small 
inclusion of this character, from the Dominion 
mine, was examined and proved to be a scap- 
olite gabbro. 
For the first mile (1-6 km.) after turning north 
at McFall’s Corners, exposures are not common 
near the road. The main outcrops are of Ottawa 
gneiss of igneous origin, chiefly biotite syenites 
and diorites, with smaller amounts of gneisses 
similar to the hypersthene-granites at the 
Emerald mine. 
Just before reaching the cheese factory, shells 
(Astarte laurentiana, Lyell) are to be seen in 
the Leda clay on the left hand side of the road. 
A mass of granulite with included small bands 
of limestone is exposed opposite the cheese 
factory. 
The rise in the road farther north is caused 
by a bank of sand and coarse gravel, which is 
exposed just beyond the summit of the rise 
and shows a stratification parallel to the outline 
of the hill. This was doubtless a sand-bank in 
the Saxicava sea close to some local source of 
fluvio-glacial material. 
Immediately north of the school-house a 
small hill of Grenville limestone is visible on 
the left hand. From here Leda clay continues 
for two-thirds of a mile (1-1 km.), and for half 
a mile (-8 km.) along the side road to the mine. 
The road skirts a hill composed of dioritic 
gneiss and impure limestone bands cut by peg- 
matite dykes. Rising over this hill the ap- 
proach to the Walker mine is covered with 
Leda clay; while at no great distance on either 
hand are cliffs and rounded hillocks of dioritic 
Ottawa gneiss.
