Knomttres From Amherst, the railway runs in a general 



westerly course and approaches close to the head 

 of the Bay of Fundy. About 4 miles (6-4 km.) 

 beyond Amherst the railway enters a narrow 

 belt of country believed to be underlain by 

 Millstone Grit. This belt is about i| miles 

 (2-4 km.) wide and extends to the northeast 

 where it is marked by a low ridge. This band 

 of Millstone Grit extends in a westward direction 

 across the head of the Bay of Fundy and there 

 rises in a marked ridge. 



14-2 m. Aulac Station — Alt. 26 ft. (7-9. m.). Aulac 



22 • 8 km. station is situated near the northwestern margin 

 of the presumably anticlinal band of Millstone 

 Grit. The low country beyond and the rising 

 ground towards the west are occupied by reddish 

 Permo-Carboniferous strata dipping over the 

 greater part of the area to the southwest at 

 angles of 15° to 30°. Between Aulac station 

 and Sackville, the railway passes around the 

 extreme head of the Bay of Fundy. 



17-9 m. Sackville Station — Alt. 26 ft. (7-9 km.). 



28 • 8 km. The low country about Sackville presumably Hes 

 on the axis of a synclinal fold in Permo-Carboni- 

 ferous strata. These measures extend for about 

 1 1 miles (2-4 km.) to the south to the foot of a 

 ridge of northward-dipping Millstone Grit 

 beds. To the northwest of Sackville, the 

 Permo-Carboniferous strata dip southwards 

 at angles of 20° to 30° and rise in a series of 

 ridges 400 to 600 feet (120 m. to 180 m.) high. 

 On the top of this upland. Millstone Girt strata 

 appear from beneath the Permo-Carboniferous 

 without any evidence of an unconformity. 



From Sackville the railway runs westerly up a 

 valley near the southern margin of the Permo- 

 Carboniferous area and for some miles continues 

 to ascend. Beyond the head of the valley the 

 railway crosses a divide with an altitude of 

 234 feet (71-3 m.), and a short distance beyond 

 crosses the northern boundary of the Permo- 

 Carboniferous area and enters a district occu- 

 pied by Millstone Grit strata. As the railway 

 continues to descend, it enters and follows a
