PART OF THE PltOVINCE OF QUEBEC. 113 



Levis, the information then at hand not being sufficient to state with positiveness that 

 the Sillery did really underlie the Levis. On the Middle River of Port Daniel also a 

 series of black graptolitic, bituminous shales is seen, resembling in character those of the 

 Eiver St. Lawrence sections at the mouth of the Marsouin and elsewhere. The Levis 

 shales and conglomerates do not, however, appear in this direction, nor the characteristic 

 green and red slates of the upper Sillery. Their absence is probably due to faults which 

 have aflected the strata in this locality, the evidences of which are visible in the broken 

 and occasionally slickensided aspect of the rocks at several points. 



In the adjacent province of New Brunswick, extending south-westerly from the 

 mouth of the Tête-à-gauche Eiver, on the Bay of Chaleurs, somewhat similar rocks are 

 found. These consist of black, green, grey and reddish slates, and, near the mouth of the 

 stream mentioned, certain bands of black graphitic slates occur, which contain graptolites 

 resembling in character also those of the Marsouin Eiver. These rocks were described in 

 the report for ]8'79,' and in this report all these rocks will be found discussed under the 

 head of Cambro-Silurian, for the reason already given for the southern Gaspé rocks. The 

 resemblance of certain red and green rocks of northern New Brunswick to the red and 

 green series of Quebec was pointed out in that report and also in 1865 by Prof. Iliud,'^ 

 and there is no doul)t that certain portions of the Quebec group are there represented, 

 though there is no trace of the fossiliferous Levis slates and conglomerates visible in any 

 part of that province, in so far as yet ascertained, with the exception of certain bauds of 

 black slates recently found by Mr. Gr. F. Matthew near the St. John suspension bridge, 

 which contain graptolites of precisely similar forms to those found in the rocks of Point 

 Levis. 



The north shore of the peninsula of Gaspé affords exceptionally good facilities for the 

 study of the fossiliferous portion and discloses a magnificent clitf section for quite 

 350 miles. In this distance the wonderful succession of folds, faults, overturns and 

 crumplings is exhibited, while the facilities for the collection of fossils are exceptionally 

 good. As much misunderstanding api)ears to exist concerning the character and age of 

 the strata here seen, a brief sketch of the strata as they occur between Cape Eosier and 

 Point Levis may be here given for the purpose of rendering this part of the subject clearer. 

 The detailed lists of fossils from various points has already appeared.' 



Beginning near the extremity of the Gaspé peninsula about two miles soiith of Cape 

 Eosier, the contact between the limestones of the Gaspé Silurian formation and the 

 Quebec grovip proper is seen, the latter consisting of hard grey slates, with hard 

 calcareous and quartzose bands and with beds of hard quartzose grit, which, in the 

 course of several hundred yards, include finely fissile red slates and hard purple-grey 

 quartzose rocks. These j)resent the same aspect as the beds of the Sillery formation, 

 south of Point Levis. 



Thence to near the extremity of Cape Eosier, where the lighthouse is placed, alternate 

 beds of red, brown, greenish-grey and black slates, with beds of dolomitic limestone and 

 hard green sandstone, occur, the quartzose beds, which are local developments only, being 

 in places well exposed.
