The scale of formations is also fairly complete, both for the 

 Silurian and Devonian in Ontario and Quebec, while in the latter 

 province the Carboniferous is represented only by the Bonaventure 

 formation which may be held to represent the upper portion of the 

 Lower Carboniferous. 



The scheme of nomenclature for the Carboniferous and Devonian 

 is completed in the provinces of Nova Scotia and New Brunswick, where 

 the liighest member of the scale is reached in these provinces in the soft 

 red sandstone of the Trias, which is, however, penetrated by great 

 masses of more recent igneous rocks, such as diabase and amygdaloid. 

 The newest member of the scale, to which, however, no special desig- 

 nation has yet been applied, is a small area of impure limestone which 

 rests upon the diabase of the North Mountain, near the head of the 

 Bay of Fundy, in Nova Scotia, and which may possibly be on the same 

 horizon with certain deposits of sandstone which occupy a similar 

 position on the western portion of the same range. These would ap- 

 pear, therefore, to be more recent than the Triassic red sandstone, but 

 their exact horizon has not yet been definitely fixed, owing to the 

 absence of determinative organic remains in these sediments.
