pebbles carrying Siluric and Devonic fossils from the beds beneath' and 

 included by Logan in the Gaspe sandstone group, are found at various 



inclinations from Chien Blanc 

 on Gaspe Bay all the way 

 around Malbay to the Grande 

 Coupe at Perce ; at places 

 these beds are nearly hori- 

 zontal, from Cannes de Roche 

 to Corner of the Beach on the 

 south shore of Malbay they 

 are nearly vertical and their 

 color varies from red to ashen 

 gray. In lithologic composi- 

 tion, the nature of the com- 

 ponent pebbles and in the 

 general aspect of this northern 

 series there is no distinction 

 from that comprising Perce 

 mountain and Bonaventure 

 Island. This latter, the typical expression and section of the Bonaventure 

 conglomerates, stands with abrupt and sheer escarpments on the east 

 and north telling, like the Catskills, of a widespread further extension. 

 The stratigraphic distinction between these higher Bonaventure con- 

 glomerates and the lower conglomerates of Malbay is only the apparent 

 unconformity between the two. The gently sloping higher mass of Perce 

 mountain seems to lie directly on the vertical conglomerates of Cannes de 

 Roche and it is the indication of this sharp unconformity that has been 

 regarded as evidence of the distinction in age in the two parts of this great

 list which might be much increased with further search.
