SAINT JOHN. 



This City and its surroundings abound in the picturesque. 

 Metamorphism, upheaval, pressure, and glaciation, have hardened, 

 tilted, faulted, twisted, hewn, polished, and striated its ancient 

 rocks, giving boldness to the rock sculpture, and intricacy and 

 variety of lineament. The rock formations of the City are re- 

 garded as Huronian (Cambrian), Lower Silurian and Devonian. 

 Carleton has Laurentian ; on this the Suspension Bridge rests. 

 Laurentian heights, separated from St. John by a valley in the 

 rear, extend eastward, (?) westward, (?) and northward to the 

 Kennebeckasis. I have thus indicated the four geological forma- 

 tions which occur in this district. In making my observations, 

 I shall start from the Kennebeckasis. We shall thus generally 

 ascend geologically. Near Torryburn we have an outcrop of grey 

 granite. This is part of an apparent granite band, which skirts 

 the south side of the Kennebeckasis, to some distance towards 

 Rothsay, and then retreats south. It also runs westward, and is 

 well exposed on the road from St. John to Sandpoint. There the 

 rocks are Syenite, being largely granitoid. The feldspar of the 

 Syenite is red and the hornblende light green. The granite of 

 Torryburn closely resembles that found in the Cobequid mountains 

 near Sutherland's lake, and the syenite (gneissoid) is not much 

 different from that associated with the marble of Five Islands, in 

 the same mountains, so that this granite band of the Kennebeckasis
