massive, their transverse measure varying from ten to sometimes 
nearly 100 feet. 
“From a point a short distance above the bridge, to one much 
farther below, these conglomerates have a breadth of very nearly 
a mile, giving a total thickness of about 1,600 feet. This great 
mass of conglomerate composes Fraser’s Mountain, towards the 
south flank of which, pre-enting the outcrop escarpment of the 
inferior part, the red and gray strata of the Millstone Grit dip 
in such a way as, without other evidence, to induce the supposi- 
tion that the one series overlies the other comformably. But on 
the west side of the East River Mr. Hartley has evidence to 
show that there is a want of conformity, at least in some places. 
“Three miles eastward of New Glasgow these conglomerates 
have a breadth of about fifty-four chains, and they are here 
immediately and conformably overlaid by the following ascend-
