165.4 km. m.). "The altitude of the station here is only 



about 20 feet below that of the uppermost 

 marine beach; and the gentle seaward slope of 

 the plain, with full exposure to the north, offers 

 unusual opportunity for the construction of a 

 beach at this level. From the car window, 

 after the train leaves the station, one can easily 

 see two low, but persistent, gravelly beaches in 

 the fields beside the track, to the south, which 

 run parallel to it for a mile or more. The high 

 broad ridge on whose outer slope they lie is a 

 till-covered ridge of bed rock, — not a beach."

INTRODUCTION. 



Riviere du Loup and the adjacent districts are situated 

 within the belt of folded and faulted strata of debatable 

 age that borders the south side of the St. Lawrence river 

 and gulf, from above Levis to the extremity of Gaspe Pen- 

 insula, a distance of about 350 miles (560 km.) These 

 measures belong to the somewhat vaguely defined assem- 

 blage of formations known as the Quebec group. The 

 strata of the Quebec group extend south westward past 

 Levis to the International boundary and beyond, and in 

 this southwestern extension of the group, it has been possible 

 from palaeontological and other evidence to indicate the 

 existence of many formations ranging in age from Pre-Cam- 

 brian to Devonian. In the northeastern extension, how- 

 ever, along the border of the St. Lawrence below Levis, 

 there does not appear to be the same complexity since by 

 nearly universal consent it has been agreed that the strata
