Art. XIV. — On the Superficial Geology of the Gaspe Peninsula ; 



by Robert Bell, C. E. ; of the Geol. Survey of Canada. 



(Read before the Natural History Society.) 



The Gaspe peninsula embraces the region lying to the eastward 

 of a line drawn across the country from the head of the Bay of 

 Chaleur to about Matan on the St. Lawrence, and measures 140 

 miles in length by 70 in breadth. 



The superficial accumulations of this district differ in their gener- 

 al character from those of the country to the west. One of the 

 most remarkable points of difference is the absence of foreign 

 boulders in Gaspe. On arriving in Gaspe Bay last spring, my 

 attention was at once arrested by the contrast presented to many 

 other parts of the country by the general scarcity of boulders of any 

 kind in the fields, notwithstanding the hilly nature of the ground. 

 On examination it was found that the loose masses were chiefly con- 

 fined to the summits and more abrupt slopes of the hills, and farther, 

 that they always belonged to rocks which existed in situ close by. 

 Daring the wholesummer, which was spent mostly in the interior of 

 the County of Gaspe, my attention was directed to the in- 

 quiry ; but I failed to discover a single stone which had not been 

 derived from the rocks of the country, until I visited Cape Gaspe 

 and Point Peter, where boulders of Laurentian gneiss were found 

 in abundance on the sea beach. While the erratic masses of the 

 interior are probably due to ancient glacial action, the presence of 

 the Laurentian boulders on the beach, on the northern sides of 

 Cape Gaspe and Point Peter, is no doubt owing to recent icebergs. 

 The proof of this lies in the fact of their occurrence only on the 

 beach, and that at points projecting into the open sea frequented 

 by drifting ice, while they appear to be altogether absent from
