Kilometres. but on the opposite side, towards the head of 

 the lake, folded "Cambrian" strata occur while 

 towards the foot of the lake, metamorphosed 

 rocks possibly of Pre-Cambrian age, are present. 

 Towards the foot of the lake and for the first 

 few miles in the rather broad valley of Mata- 

 pedia river, there are no rock exposures. 



72 -9 m. Amqui Station — Alt. 532 ft. (162-1 m.). 



115-7 km. Beyond Amqui, rock cuts occur along the rail- 

 way in dark slates with occasional beds of fine 

 sandstone and thin beds of limestone. The 

 measures in most places lie with low angles of 

 dip but in places are highly inclined. 



Approaching Causapscal the railroad crosses 

 the river to the east side of the hitherto broad 

 valley but which in this neighbourhood 

 contracts. 



86-3 m. Causapscal Station — Alt. 454 ft. (138 -4m.). 



138-9 km. Beyond Causapscal, the river valley again 

 broadens and cuts across a six-mile wide belt of 

 greyish and yellowish sandstones and arenaceous 

 shales. These measures represent the Gaspe 

 sandstone series and are presumably of late 

 Devonian age. The strata are highly inclined 

 in the form of a synclinal fold. They terminate 

 a few miles to the west of the river, while in an 

 easterly direction they extend continuously 

 for 150 miles (240 km.) to the extremity of 

 Gaspe peninsula. At several places in the 

 interior of Gaspe, the Devonian sandstone 

 series rests unconformably upon Silurian mea- 

 sures. On the Matapedia, it was supposed by 

 Logan, that the Silurian and Devonian were 

 conformable. 



92-8 m. Beau Rivage Station — Alt. 366 ft.(iu -6 m.). 



149-4 km. Beyond Beau Rivage, the Silurian area is again 

 entered and numerous rock cuts in the highly 

 inclined, dark grey calcareous slates occur along 

 the railway to Matapedia Junction, where the 

 Matapedia joins the Restigouche river. 



Below Beau Rivage, the river valley gradually 

 contracts and the bordering hills rise to higher 

 heights. The various tributaries of the Mata- 

 pedia river irrespective of their sizes, occupy
