Kilometres "lile (o • 8 km.) bcyond Maccan Junction, the 

 railway crosses the northern boundary of the 

 Productive Coal Measures and enters a narrow 

 belt of Millstone Grit beds which dip beneath 

 coal measures. Where traversed by the railway, 

 this band of Millstone Grit has a width of about 

 f mile (i • 2 km.) . The country traversed is low. 

 To the west are visible the highlands on the 

 New Brunswick shore of the Bay of Fundy, 

 distant about i8 miles (28 km.). The high, 

 detached hill is Shepody mountain composed of 

 lower Carboniferous strata. The continuous, 

 somewhat lower upland beyond Shepody moun- 

 tain, is Caledonia mountain which stretches 

 westward for many miles parallel with the shores 

 of the Bay of Fundy and is formed chiefly of 

 Pre-Cambrian strata. 



The Millstone Grit strata are succeeded on 

 the north by a wide area of the Carboniferous 

 Limestone series in which the strata dip south- 

 ward at angles of 20° to 40°. These measures 

 where traversed by the railway occupy a belt 

 about 3f miles (6 km.) wide. Towards the 

 northern edge of this belt, the railway passes 

 close to a gypsum quarry, visible on the western 

 side of the railway. 



About 5 miles (8 km.) beyond Maccan Junc- 

 tion, the railway enters a broad band of Permo- 

 Carboniferous strata stretching westward from 

 the head of the Bay of Fundy to the shores of 

 Northumberland strait. These measures over- 

 lap the Carboniferous Limestone series on the 

 south. 



8 m. Amherst — Alt. 63 ft. (19-2 m.). The very 



12-9 km. low country around Amherst is underlain by 

 gently dipping reddish sandstones and shales 

 of Permo-Carboniferous age. These measures 

 extend northeastward to Cumberland strait, 

 distant about 20 miles (32 km.) . The tract of 

 country between the head of the Bay of Fundy 

 and the Gulf of St. Lawrence is everywhere low, 

 probably nowhere reaching an altitude greater 

 than 100 feet (30 m.).
