m, 69; interval 450 feet; Indian Cove, 48. Mr. Brown’s 
susie section extends to a depth « of 1860 feet, or along 5000 
yards at a dip of 7° tothe N. 6 
Mr. Brown ‘“ concludes pi a best information in his pos- 
session that the productive Coal-measures exceed 10,000 feet,” but 
w nothing in Cape Breton to justify the supposition. He 
pekirts ts that, “ owing to several extensive dislocations, it is im- 
possible to ascertion their total thickness with any "degree of 
.’ ITcan only suggest, with deference to his Jong ex- 
perience and acknowledged skill, that the structure of the east 
Ci 
one ins stance at b least, that of Cow agate the south dips are 45°, 
and the basin is sharp and narrow, greatly resembling the end 
of one of the anthracite basins of Pennsylvania. As at Sydney, 
at Glace Bay, so here at Cow Bay there are bat four 
workable oak beds in about 1500 feet of productive measures, 
and they are, no doubt, the Glace Bay beds.’ 4 
Sir William Logan, Sir Charles Lyell, Prof. Dawson, and other 
geologists who have described the Coal-measures of Nova Scotia 
and New Brunswick, agree in assigning to them an almost im 
SS Sg tee ah eat 
saadible thickness. “The entire section of the e Joggins,” writes — 
Sir William Logan, “contains 76 beds of coal and 90 distinct 
Stigmaria underelays, ” with “24 bituminous limestones,” in “a 
vertical thickness of 14,570 feet.” — 
When we analyze the eight divisions into which this immensé — 
mass has been distinguished, we find them thus constituted:
