Miles and 

 Kilometres. 



22-3 m. Avondale Station — Alt. 151 ft. (46 m.). At 



35-9 km. Avondale, the railway enters the upland region 

 of Silurian and older strata and follows a series 

 of low valleys that cut completely through it. 

 The elevated district extends in an eastward 

 direction for about 25 miles (40 km.) and ends 

 in a promontory on the sea coast. In the 

 opposite direction, the highland joins the 

 central upland area that extends, though with 

 some interruptions, in a southwesterly direction 

 for about 200 miles (320 km.) and forms the axis 

 of the peninsula of Nova Scotia. 



32 m. James River Station — Alt. 255 ft. (77 • 7 m.) . 



51-5 km. Shortly before reaching James River station, 

 the railway leaves the upland area of disturbed 

 Silurian and older measures and enters a low 

 rolling area occupied by disturbed Carboniferous 

 strata presumably belonging to the Windsor 

 series. The low-lying Carboniferous area 

 extends eastward to the sea. It is bounded on 

 the north and east by the highlands of Silurian 

 and older strata, while on the south it is limited 

 by an upland area of strata belonging to the 

 Riversdale-Union group. 



41-5 m. Antigonish — Alt. 20 ft. (6-i m.). Beyond 



66-8 km. Antigonish the railway passes along the seaward 

 border of the Carboniferous area. For a 

 number of miles the low-lying country is under- 

 lain by measures supposed to belong to the 

 Windsor series, but, farther east, the railway 

 enters a bordering area of older Carboniferous 

 strata. 



70 -2 m. Harbour au Bouche Station — Alt. 271 ft. 



113-0 km. (82 • 6 m.) . One mile (i • 6 km.) beyond Harbour 

 au Bouche, the railway enters a wide area of 

 folded and faulted measures belonging to the 

 Riversdale-Union group. These measures form 

 the western shore of Cabot strait, distant a few 

 miles to the east, and have been traced almost 

 uninterruptedly as far as the neighbourhood of 

 Windsor 150 miles (240 km.) to the southwest.
