crossing 01 Rights river, the railway again 

 crosses the river and shortly re-enters the area 

 of the Limestone series. The railway follows 

 the river closely and along it occur cliffs of 

 gypsum. The southern boundary of the Con- 

 glomerate series lies just north of the railway. 

 The strata of this series dip in a general southerly 

 direction at angles varying from quite low to as 

 high as 70°. One mile (i-6 km.) beyond the 

 second crossing of Rights river, the railway 

 crosses it again where it issues from the higher 

 ground to the north. 



Beyond the third crossing of Rights river the 

 railway passes along the sides of a series of small 

 streams, the alternate ones flowing respectively 

 east and west. Along the streams occur low cliffs 

 of gypsum, while in places between the heads of 

 streams the presence of gypsum is indicated 

 by the characteristic "sinks". The Limestone 

 series, as developed along the line of the railway, 

 consists of a basal limestone member possibly 

 about 10 feet (3 m.) thick overlain by about 

 200 feet (60 m.) of red sandstone and shale, above 

 which lie about 200 feet (60 m.) of gypsum. The 

 basal limestone rests on greenish conglomerate of 

 the Conglomerate series which west of a point 

 about 1 1 miles (2-4 km.) west of the third cross- 

 ing of Rights river, is confined to a narrow zone 

 bordering the steep front of the upland which 

 rises a short distance north of the railway. 



The steeply rising hills are underlain by closely 

 folded greywacke varying to an impure quartzite 

 and interbedded with a very siliceous slate. 

 These measures compose the James River 

 formation which is possibly 5,000 feet (1,500 m.) 

 thick and is presumed to be of Ordovician age. 

 The strata are penetrated by irregular intrusions 

 of diabase and rhyolite and by one mass of granite 

 underlying an area of several square miles. 



About 8 miles (12-9 km.) from Antigonish the 

 railway crosses James river, a southward flowing 

 stream which issues from the hills through a 

 deep, V-shaped valley. At the crossing of
