North of Upper Dorchester station, the 

 railway again enters an area underlain by 

 Albert strata and these are capped by coarse 

 grey Millstone Grit conglomerate forming a low 

 ridge rising just east of the railway. 



34-9 m. College Bridge Station — Alt. 32 ft. (9 • 7 m.) . 



56-2 km. In the vicinity of College Bridge station the 

 Albert series underlies a very limited area on 

 the east side of the river. On the west side of 

 the river, this series with its "oil-shales" is 

 more fully developed over a band about i mile 

 (i • 6 km.) wide which extends in a northwesterly 

 direction for about 6 miles (9 • 6 km.) to the banks 

 of the Petitcodiac river, opposite the Stony 

 Creek oil and gas field. 



A short distance beyond College Bridge sta- 

 tion, the railway again enters an area underlain 

 by lower Carboniferous strata — red shales, 

 sandstones and conglomerates. These measures 

 occupy the lower slopes of the ridges bounding 

 the Memramcook valley but the summits of 

 these hills are capped by nearly horizontal 

 grey, Millstone Grit sandstones and con- 

 glomerates. 



As the railway follows northward up the 

 Memramcook river, the valley gradually con- 

 tracts. About 4I miles (7-2 km.) beyond 

 College Bridge station, the railway passes 

 through a series of cuttings in granite. These 

 exposures belong to an area of granite having 

 a maximum diameter of about | mile (o-8 km.) 

 and which apparently represents an island-like 

 projection of the floor on which the Carboni- 

 ferous measures were deposited. 



41-5 m. Calhoun Station^Alt. 54 ft. (16-4 m.). 



66-8 km. Beyond Calhoun station the valley of Mem- 

 ramcook river becomes very shallow and 

 gradually dies away. The surrounding country 

 is very even in character and is presumed to be 

 underlain by nearly horizontal strata of Mill- 

 stone Grit age. Four and a half miles (7-2 m.) 

 beyond Calhoun station the railway crosses a
