M les and^ being of Uppermost Silurian or lowermost 

 Devonian age. These measures along the 

 northern base of Mount Wissick repose on strata 

 of the Quebec group over which it seems likely 

 they have been thrust. 



A short distance beyond Cabano, the railway 

 swings away from the lake and following a 

 westerly direction crosses the boundary of the 

 Silurian area about 2 miles (3-2 km.) west of 

 Cabano. From this point the railway crosses 

 the zone of the Quebec group strata that borders 

 the lower St. Lawrence, and which at this point 

 has a width of about 30 miles (48 km.). These 

 measures are usually vertical or steeply inclined 

 to the south suggesting that the strata for the 

 greater part occur in a series of overturned anti- 

 clines. The beds occur in alternating bands of 

 grey sandstones and grit, and grey, green and red 

 slates. These measures have been classed with 

 the Sillery and considered to be of Cambrian age. 

 Possibly, however, other strata are present. 

 The strata are exposed in numerous cuttings 

 along the railway. 



Westward from Cabano, the railway ascends 

 through a country occupied by long low ridges 

 and hills and 19-3 miles (31 km.) from Cabano 

 station crosses a summit level having an alti- 

 tude of 1,324 feet (403-5 m.). Beyond this, 

 the railway gradually descends through a less 

 broken country to the lower levels bordering 

 the St. Lawrence.

192-5 km. Riviere du Loup is the junction point of the 

 Temiscouata railway and the Intercolonial 

 railway.
