Knomeu-M. ^iver, one of the larger tributaries of the St. 

 John. The valley of the Madawaska is flat- 

 bottomed and rock exposures are rare. Such 

 outcrops as occur are of dark slate of Silurian 

 age. 



59-3 m. Ste. Rose Station — Alt. 504 ft. (153-6 m.). 



95-4 km. About i| miles (2-4 km.) beyond Ste. Rose 

 station, the railway approaches the foot of 

 Temiscouata lake, out of which the Madawaska 

 river flows. The railway for a number of miles 

 closely follows the southwestern shore of the lake. 

 Temiscouata lake is about 24 miles (38-6 km.) 

 long and varies between i and 2 miles (i • 6 and 

 3-2 km.) in width. 



The strata along the shores of the southern 

 part of the lake consist of tightly folded and 

 contorted dark grey slates and argillaceous 

 limestones with occasional beds of sandstone. 

 These measures are of Silurian age and are ex- 

 posed in a number of cuttings along the rail- 

 road. 



68 I m. Notre Dame du Lac Station — Alt. 517 ft. 



109-6 km. (157.6 m.). The folded crumpled dark slates 

 occur in a number of cuttings along the railway 

 for about 3 miles (4 • 8 km.) beyond Notre Dame 

 du Lac station. Beyond this for a distance of 

 several miles occurs a thick series of strata in 

 places containing fossils of Niagara or perhaps 

 Clinton age. The series in part consists of slates 

 and sandstones, in part of fine-grained tuffs and 

 volcanic conglomerates. The volcanic strata 

 consist of slightly waterworn fragments of 

 andesite, devitrified glass, etc. The same strata 

 are repeated on the northeastern shore of the 

 lake. 



76-3 m. Cabano Station — Alt. 500 ft. (152-4 m.). 



122-8 km. On the northeast shore, opposite Cabano, 

 Mount Wissick rises 550 feet (167-6 m.) above 

 the lake, to an altitude of 1,035 feet (315 m.). 

 Mt. Wissick is formed of Silurian strata dipping 

 to the southeast at angles of 15° to 70°, and 

 these measures there yield a section of above 

 1,950 feet (595 m.) of strata which in places are 

 richly fossiliferous and have been described as
