NOVA SCOTIA. 563 



Canaan is N.E. and S.W., and they extend from that place westward 

 to the Nictaux Kiver. Westward of Nictaux River, as already men-

well as those of the last mentioned formation, are interrupted by great 

 masses of granite, which form the hills along the south side of the 

 Annapolis River, from a place called Paradise to Bridgetown, and 

 with some interruptions nearly as far as the town of Annapolis. This 

 granite is hardly distinguishable in its character from that of the south 

 coast of the province, except that it is perhaps more felspathic, and 

 less largely and perfectly crystalline. Its age, as already stated, must 

 be that of the newer Devonian or older Carboniferous. Near Paradise 

 it is traversed by veins of reddish compact felspar, with crystals of 

 schorl and transparent smoky quartz. The latter mineral is found in 

 very large and beautiful crystals scattered in the surface rubbish, and 

 is collected and sold by the inhabitants. 



Westward of Pai'adise, I have not traced the equivalents of the 

 Upper Silurian; the Devonian beds, as already stated, appearing at 

 Moose and Bear Rivers. At the Joggin near Digby, the slates, 

 probably of this series, are broken up and much altered by masses or 

 dikes of porphyritic rock. At one place here I found the strike of 

 the bedding to be N. 15° E., while that of the slaty structure is N. 

 45° E. Westward of this place the slates in a highly metamorphic 

 condition continue with general N. E. and S.W. strike to the coast 

 of Clare, where a con.siderable breadth of country is occupied with 

 olive and gray slates, quartz rock, and occasional dikes of greenstone. 

 At Montengan these beds include veins of iron pyrites, one of them a 

 foot in thickness. I have not been able to observe the junction of the 

 group now under consideration witli the metamorphic district of the 

 Atlantic coast; but I think it probable that the limit of the altered 

 Upper Silurian rocks in this direction is near Beaver River. 



With respect to the age of these rocks, it is certain that the fossil-
