Fossils 

 noted by 

 Mr. Fletcher. 



S.E. mag. < 40 and have sandstone beds with much felsite sand, 

 and with some pebbles of red felsite and of black siliceous slate. Else- 

 where in this cutting the dip of the beds is S. 20 E. mag. < 60 and 

 the hade or slope of the cleavage N. 70 W. mag. < 85. These 

 sandstones hold a Lingulella similar to L. Selwyni. 



Westward of this on the railway there is a space of 1,100 feet 

 without exposures, and thin cuttings in the same gray rocks where 

 the dip is S. 50 W. mag. < 50 , and a little further, S. 20 W. mag. 

 < 80. These gray rocks continue along the railroad about 1,500 feet 

 further, and are supposed to be about the middle of the Etcheminian. 

 Passing up from Young's house across the railway to the road, one 

 meets with ledges of gray, cream-weathering argillites which belong 

 to the upper division of the Etcheminian. They extend from the 

 school-house along the highway toward Barachois, and southwardly 

 along the west side of the valley of Young's brook. 



Along the shore of Long island passage at the foot of this ridge of 

 argillites on the western side are dark-gray slates and gray flags of the 

 St. John terrane. 



A section in a south-east direction across the Cambrian basin from 

 Young's point, on St. Andrews channel, for half a mile, to the syenite 

 of the Boisdale hills would give the following succession : 

 500 feet red and gray slates and sandstones = Lower Etcheminian. 



The base of the terrane is concealed by the water of St. Andrews 



channel. 

 1,500 feet tine gray and some coarser argillites. Anticlinal in Upper 



Etcheminian. 



300 feet in valley of Young's brook == Part of St. John group. 

 300 feet unexplored to border of syenite as given by Mr. Fletcher. 



Returning to Young's house and the shore of St. Andrews channel 

 in front of it, the red slates which were seen east of Young's brook 

 are here well exposed in a low cliff along the shore. They are more 

 fossiliferous here, and when not too strongly cleaved show well-preserved 

 examples of Lingulella, especially L. Selwyni. 



Fossils were first observed by Mr. Fletcher, and subsequently by 

 Messrs. Weston and Robert of the Survey staff, who were sent here to 

 collect. It is not quite certain to me that they collected from Young 

 point as their collections are marked McAfee point, and their speci- 

 mens are larger than those I found, but the similarity of the fossils 

 show they were from the same division of the Etcheminian. The 

 collections made here by Messrs. Weston and Robert were some years 

 ago placed in the writer's hands for study, and they appeared to
