Miometres pronounccd valley which eventually turns to 

 the west and joins the broad valley of Memram- 

 cook river. Before entering this main valley, 

 the railway passes through a long cutting of 

 grey Millstone Grit sandstone dipping south- 

 ward at an angle of 20°. 



On entering the Memramcook valley, the 

 railway bends to the north and traverses the 

 low diked land bordering the river. On the 

 opposite shore of the river rises a rounded ridge 

 of Millstone Grit grey sandstone and quartz 

 conglomerate dipping southward at low angles. 

 Before reaching Dorchester station the railway 

 passes out of the Millstone Grit area and enters 

 one occupied by a coarse red conglomerate of 

 lower Carboniferous age. The two formations 

 dip to the southward at angles of 10° to 25° and 

 appear to be conformable though they are 

 presumably of widely different ages.

47 • I km. Beyond Dorchester station the rising ground on 

 the east is occupied by red conglomerates and 

 sandstones capped on the summits of the 

 ridges by the grey strata of the Millstone Grit. 

 Approaching Upper Dorchester station, the 

 low-lying ground immediately adjacent to the 

 railway is underlain by strata of the Albert 

 series which have been correlated with the 

 Horton series of Nova Scotia, and are con- 

 sidered to be of early Carboniferous age. 



32 m. Upper Dorchester Station — Alt. 27 ft. 



51 -5 km. (8-2 m.). On the western side of Memramcook 

 river, just above the highway bridge at Upper 

 Dorchester, are low cliffs of the Albert series 

 which at this point lie in a flat anticline. The 

 strata in these low cliffs are dark shales or "oil- 

 shales" very rich in hydro-carbons. The 

 lower slopes of the rising ground west of the river 

 are occupied by gently dipping red sandstones 

 and grits while the summit of the ridge is 

 formed of the grey sandstone and quartz 

 conglomerate of the Millstone Grit. On the 

 opposite side of the ridge somewhat similar 

 strata occur overlying the Albert series which,
