carboniferous," an underlyi of red and gray sandstones and 



shales, holding Carboniferous plants, extending from near Cape Wolfe 



toward the north point, and a similar series found a1 Govern 

 Island and G alias Point in Hillsborough Bay. These are undoubtedly 

 extensions of the Carboniferous of Nova Scotia. All the resl of the 

 island is occupied with Triassic rocks; in our place, II g island in 

 Richmond Bay, associated with trap. The general relations of thi 

 rocks are seen in the. sections. 



The beds of the Triassic series, as seen in Prince Edward [aland, 

 consist chiefly of soft red sandstone, with Borne buff-coloured beds and 

 red and mottled clays. Associated with them are conglomerates and 

 hard calcareous and concretionary Bandstones, passing into bands of 

 arenaceous limestone, which is in some places a dolomite. The 

 following section in Orwell Hay and its vicinity Bhows the beds 

 resting on the Upper Carboniferous of G alias Toint, and may he 

 taken as typical, it is in ascending order : —

1. Bright red sandstones with white hands .... 30 



2. Red shales with white stains and red sandstones with 



cylindrical casts of fucoids . . . . . .60 



3. Red and purplish sandstones with gray hands and layers 



of ferruginous conglomerate with obscure remain- of plants 



4. Beach, probably representing soft beds . . . .48 



5. lied flaggy sandstone with conglomerate and concretions of 



red oxide of iron, containing remains <if plants . . 50 



6. Bright red sandstones and red shale with greenish Btains  30

8. Bed shale and green bands capped with bright red sand- 



stones . . . . . . . . .75

(Here the section is broken by Orwell Bay, which prob- 

 ably represents some thickness of soft beds.) 



9. On the high cliffs near Belfast arc very brighl red sand- 

 stones and shaly beds, with gray blotches and cylindrical 

 fucoids — about . . . . • • • 120 



10. Over the last are seen, in the country easl of Belfast, soft red 

 sandstones with beds of conglomerate with rounded quartz 

 pebbles and arenaceous cement (thickness uncertain)

As seen in this section, the whole thickness of these beds cannot 

 much exceed 500 feet. Of this the lowest 270 feet, being Nob. 1 to
