456 HONEYMAN ON GEOLOGY OF NEW BRUNSWICK. 



we were prevented from crossing the river and examining the 

 copper mine. 



In spite of our misfortune we examined the rocks accessible : 

 characteristic specimens of rock were also brought from the mines. 

 These enabled me to form an opinion of the rocks containing the 

 deposit of copper. We were disappointed however in not being 

 able to examine the mines and deposits. The prevalence of schists 

 and magnesian rocks indicate an age and condition of formation 

 similar to Tilt Cove, Newfoundland. I consequently concluded 

 that the band of rocks was of lower silurian age, (metamorphic). 



Afterwards, Ave visited the Grand Falls, about twelve miles 

 farther up the river. On our way we glanced at the rocks on the 

 river, as they appeared at intervals. They seemed to be similar to 

 those of the Copper Mines; at length we reached the Falls, com- 

 ing upon them from above. The scene far surpassed that of the 

 Pabineau Falls, but our old enemy the mosquitoes, of monstrous 

 size, and in numbers formidable, assailed in every direction, so thai 

 I could hardly manage to secure a characteristic specimen of the 

 rocks over which the waters rushed. The rock is a schist, highly 

 siliceous, having the appearance of an amygdaloid. Its hard con- 

 stitution has enabled it to resist the degrading action of the waters ; 

 its elevation has given them great scope for descent. I had no 

 hesitation in regarding; the rocks as a continuation of the band of 

 the mine, and as being of lower silurian age. 



Subsequently we ascended the river from the bridge at Bathurst. 

 On the sides of the river, below and above the bridge, exposed 

 layers of a red sandstone shewed that we were within the area of 

 the carboniferous triangle. Ascending the river on the south side 

 the same kind of sandstone continued until we reached the Rough 

 Waters. I was shewn nodules of copper ore (grey sulphuret) 

 which were found in this sandstone. The ore is rich, but the supply 

 is limited, as Nova Scotian experience, under similar circum- 

 stances, would lead us to expect. 



At the Rough Waters I found matters altogether different from 

 what I anticipated. I expected to find the granite of the Rough 

 Waters overlaid by Lower Silurian (metamorphic) slate, as we have
