fragments of black sliale constituting a kind of breccia. The sand- 

 stone underlying this bed of trap contains small nodules of selenite 

 and narrow veins of reddish fibrous gypsum. No other volcanic 

 rocks occur in the coast section near these 

 trap conglomerates. Westward of this place, 

 the section is occupied for about tlu-ee miles 

 by soft red sandstones with greenish bands, 

 dipping generally to the south-west : some of 

 them arc divisible into very thin layers, whilst 

 others are compact and form beds several feet in 

 thickness. 



Near Moose River, the red sandstones meet 

 black shales and hard gray sandstones of the 

 Carboniferous system, containing Cordaites, 

 Ferns^ and Lepklodendra* 



At this j^lace the junction of the two groups 

 of rocks was not, at the time of my visit, well 

 exposed in the cliff, and had the appearance of a 

 fault ; but as seen in the horizontal section on 

 the beach, the red sandstone with a south-west 

 dip seems t.o overlie unconformably the carboni- 

 ferous strata, dipping at a high angle to the 

 E.N.E. On the west side of Moose River the 

 Carboniferous strata include three large masses 

 of trap which have altered the grits and shales

succeeded by another great mass of trap, form- 

 ing a lofty cliff, and in part at least resting on 

 soft red sandstone which it must have over- 

 flowed when in a fluid state. At the western 

 side of this mass, or rather bed of trap, its upper 

 surface is seen to dip to the W. S.W., and is 

 conformably overlaid by red sandstones similar 

 to those already described. These continue with 

 various dips to a cove where there is a break in the section, westward 

 of which the coast exhibits the interesting and complicated appearances 

 which I have endeavoured to represent in Fig. 28.
