J. P. Lesley on the Coal-measures of Cape Breton. 183 
_ Beneath these rocks lie formations of clay (including coal beds, 
one seven or eight feet in thickness), which form the west end 
Our section of 907 feet of rock, commences at the headland in 
the centre of the synclinal and runs along the coast southward. 
Commencing at the same headland and running along the coast 
westward, a similar section may be obtained of the same rocks as 
they rise from the synclinal in that direction at the same low dip. 
Such a section would be from Cadougan’s Creek, which corres- 
ponds to Little Glace Bay, to the mouth of Lingan Bay, which 
in like manner corresponds to Great Glace Bay. Many interes- 
ting variations in the metals would appear from such a compari- 
son. ile the general regularity and parallelism is remark- 
able, there are numerous minor irregularities; some fine instances 
of false bedding and local deposition; lenticular masses of sand 
separating adjacent mud-rocks; passages of shales into sand- 
stones, and wice versa; gradual coalescing of scattered nodules 
of clay iron-stone into solid plates, or their gradual pervading 
of a thick bed of fire-clay, hardening it into so refractory a rock, 
that its outcrop forms a reef far out to sea. Instances occur of 
of the splitting of coal-beds. The Lingan bed, for example, has, 
on the sea-shore, a clay parting of half an inch, which in a quar- 
ter of a mile inland, thickens to nine inches; and then, in four 
r ing, lea the 
creased to ten feet of tough rock, between two 6 inch beds of coal. This increase 
feet takes place without crush in a distance of only three or four yards,
