110 Division 3 of the Etcheminian. 



This section shows a thickening of the two lower divisions of the 

 Etcheminian, but the upper division is greatly reduced in bulk, per- 

 haps by erosion prior to the deposition of the St. John terrane. The 

 beds of Division 1 are correlated with those of Dugald brook, partly 

 by lithological resemblances, and partly by their fossil contents. Col- Fossils of 

 lections were made from Assise d, of Division 1 , and the following Diviskm 1 on 



fossils determined : Boundary
