on St. Andrews channel. The Etcheminian terrane is exposed at the 

 north-east end of this basin, but the structure is complicated by faults 

 and folds. 



At George river station is the north-eastern end of a long ridge of 

 syenitic rocks which extend the whole length of the basin, bordering 

 it on the south-eastern side. The basal conglomerates of the Etche- Basal 

 minian are wrapped around the north-eastern end of this ridge, and of"^ 1 " 

 around the corresponding end of Long island. On this island, howe- Etcheminian 

 ver, they rest on Coldbrook felsites and breccias, and no syenite is basin. 

 visible. In the railroad cuttings at George river station the contact 

 of these conglomerates with the syenite can be seen at several places. 

 They fill hollows in the syenite and dip N. mag. and N. 20 E. mag. 

 < 60. Felsite boulders are common in these conglomerates. 



Westward of the station and beyond a brook and an embankment, 

 the conglomerates are seen to rest on dark purplish-gray fine-grained 

 felsite similar to those of Ixjng island and presumably of the Coldbrook 

 terrane ; one bed has boulders six inches to two feet in diameter, of 

 dark purplish-red felsite, some of which are quite siliceous. This is 

 followed by fine-grained earthy felsite with crystals of kaolinized 

 feldspar, showing ancient weathering. With these conglomerates is a 

 hard purplish-red slate, and a compact feldspathic rock seamed with 

 epidote. The dip here is N. 10 W. mag. < 85 ; but the prevalent 

 dip in the cutting is to the S.S. W. 



Off the railroad track one hundred yards to the south-west is a mass 

 of gray slate, etc., which would seem to be the upper division of the 

 Etcheminian terrane. Here the railroad track begins to turn to the Associated 

 south, and after passing a space of about eight hundred feet, one sandstones 

 comes to purplish-red slates and purplish-gray sandstones of the lower 

 division of the Etcheminian. The cleavage planes here dip N. 55 E. 

 mag. < 90, but the dip of the beds is N. 5 W. mag. < 50. The 

 shaly layers below the sandstones have a few Lingulellas, not well 

 preserved. These beds are capped by Lower Carboniferous limestone 

 extending to the shore. 



At Young's brook just beyond this hill, these red slates and sand- 

 stones are cut off by a fault, and the rocks which appear to underlie 

 them are gray. These show on the shore and along the railroad track 

 and are the base of the upper division, which extends thence along the 

 west side of the valley of Young's brook to the highway and beyond. 

 The valley itself and its eastern side up to the syenite are occupied by 

 dark -gray slates &c., a portion of the St. John terrane. The purpUsh
