extends to Kennebecasis Bay. Across this broken 

 country stretch a number of bands of solid and massive 

 granite rock, in ridges and hills covered by a thin growth 

 of stunted firs and spruces, or often turned into desolate 

 barrens by repeated forest tires. ISTorthwestward towards 

 Boar's Head is a small area covered by coarse red conglo- 

 merate and sandstone, of Carboniferous age. 



All these formations have a general strike approxima- 

 ting north-east and south-west. Following them south- 

 west, at the mouth of the harbor, we find the Devonian 

 slates continuing along the " Bay Shore," where the well- 

 known "Fern Ledges" have afforded beautiful specimens 

 of ferns and insect wings. On this side of the harbor 

 the igneous rock is found to increase in width, forms 

 most of Carleton Heights, and appears in several 

 hills along the shore. The Cambrian slates of the city 

 cross to Carleton, but are cut out beyond the Falls by 

 a faulting wliich has caused the felsites and limestones 

 to the north to encroach on them, and to the south- 

 west of the Falls everything is buried under ridges of 

 glacial drift. The limestones and gneisses continue across 

 the river and extend to the west and south-west for a 

 long distance. One of the bands of granite crosses over 

 from Indiantown to Pleasant Point, and makes a high, 

 round-topped ridge on the west side of the river along the 

 the Narrows. Other masses of granite appear beyond, 

 but have been less carefully studied. 



The succession of the stratified rocks in point of age 

 is as follows : 



1. Limestones, quartzites and gneiss. 



2. Felsites and trap. 



3. Cambrian slates. 



4. Devonian slate and sandstone. 



5. Carboniferous conglomerate and sandstone.
