agree best with those of Lower Ordovician age, and so were considered 

 to be of that system. The dips and strikes marked by Mr. Fletcher 

 on his map appeared to agree with this view, as they showed a series 

 parallel to the shore of St. Andrews channel, whereas the Cambrian 

 beds in Long island passage exhibited a different strike. A personal 

 visit to the locality has now convinced me that these beds, in place of 

 being at the summit of the Cambrian, are towards its base, and are in 

 fact of the lower division of the Etcheminian. 



The fossiliferous series extends in a low cliff along the shore of St. 

 Andrews channel from Young point nearly to the mouth of Young 

 brook, the cliff falling to the level of the beach as it approaches that 

 stream. As the section runs nearly, on the strike of the beds, only a 

 small part of the lower division is exposed. The highest beds seen 

 come from beneath a mass of Lower Carboniferous limestone on Young Section of 



.Lower 



point, and progressively show lower beds for a distance of 150 feet along Etcheminiau 

 the shore. There is no lack of fossils, but the cleavage being transverse 

 to the bedding those in the slates are greatly obscured, but in the sandy 

 beds they are less distorted. It is in the lower beds, including a bed 

 of grit 2 to 5 feet thick, that the greatest variety of fossils is found.

Sandy shales and sandstones, chiefly gray sandstone and purplish- 

 gray slate, the former predominating. The sandstones have pebbles 

 and nodules coated with hematite, vertical worm burrows, (Areni- 

 colites and Monocraterion), and shells of Lingulella are scattered 

 over the layers. 



Purplish-gray sandy shale. 



Sandy layer with Lingulella, &c. 



Purplish-red shale with Lingulella, &c., and a cream-coloured layer 



of felsite sand. 



Red sandy slate, with scattered Lingulella, sharply folded against 

 the bed of grit. 



Grit, gray above, purplish-red below. Pebbles of slate, felsite 

 quartzite and black silicious slate. Lingulella common. 



Purplish-red shale, colour deepened in the seams and cleavage planes 

 by hematite. Lingulella common.
