40 THE CANADIAN NATURALIST. [Vol. X. 



Nepisiguit river or great Carboniferous plain, on the east, which 

 exhibits, in general, a uniform or gently undulating 'aspect, and 

 is without any eminences, except the Blue Mountains already 

 spoken of and one or two lesser ridges. This area has a gradual 

 descent from the sources of the rivers debouching into the Bay 

 (which vary in length from fifteen to forty-five miles) towards 

 the low shores of that sheet of water. The rocks underlying it 

 have evidently undergone great denudation, especially near the 

 coast ; for, although much disturbed — the strata in many places 

 being upturned vertically — they nevertheless exhibit a compara- 

 tively even surface. 



To the south-east of the Bay Chaleur stretches the great Carbo- 

 niferous area of the Province. It is a flat district, whose surface 

 as far south as the Bay of Fundy does not attain a greater 

 height than 250 to 275 feet and slopes very gently down beneath 

 the waters of the Gulf of St. Lawrence. 



Bearing in mind the topographical features of this region, we 

 can now mark their influence on the course of the glacier which 

 once occupied the depression of the Bay Chaleur and overspread 

 the district to the south of it. 



GLACIAL STRI^. 



Three sets of striae occur in the region embraced in my obser- 

 vations. I will note some of the most accessible localities where 

 they are to be seen. No two of these sets have been noticed in 

 any one area. 



The first set of striae was observed in the Restigouche valley 

 and on the hills to the south of it, as well as eastward along the 

 Bay shore as far as Jacquet river, extending over a district 

 about forty miles in length. The particular localities where expo- 

 sures occur are as follows : 



(1) At Campbellton, on the west side of a trap hill or roche 

 moutonnee at the Intercolonial railway snow-shed. This hill 

 stands about fifty feet above the level of the river, and is 

 rounded and polished on the west side, having a crag-and-tail 

 form. 



(2) At the school-house in the village a similar mass of rock 

 is striated and polished on the west side, and broken off" on the 

 east. 



(3) On the road to Parker's lake, three miles south-west of 

 Campbellton, near the summit of one of the parallel ranges of
