and the Silurian at two of the points cited by Dana — Cape St. 
George and north of Sutherland Lake — has been seen by the 
writer. In Fletcher's account th(^re is this stat(!mcnt: "On the 
shore of the little laki^ south of Sutherland Lake, whitish, 
greenish and bluish-f2;ray nii(;aceous, compact (juartzite and 
argillite are cut by dyk(;s of dark-f^ray calcareous trap. Rocks of 
similar character are found in the brook from this lake, as far 
as the road, where they contain fossils, nmch of the land being; 
barren."^ 
This is the only mention of Sutherland Lake that I have been 
able to find, and, coming in Fletcher's account closely following 
the mention of the localities on the East River of Pictou, it may 
well be the reference frorii which Dana assumed the location 
given in the last edition of his Manual. 
Conclusion. — Thus it will be seen that the conclusion that 
there was folding at the close of the Ordovician in Nova Scotia 
is not supported by fact. Not only are there no undoubted 
Ordovician rocks in this province, but in no place has a contact 
showing an unconformable relation between supposedly Ordovi- 
cian rocks and rocks of a later date been recorded. 
New Brunswick and Eastern Quebec. 
In discussing the relation of the Ordovician and Silurian rocks 
within the area designated above, I shall consider the localities 
in the following order: — 
Lakes Temiscouata and Metapedia; Carleton County and 
central New Brunswick; Gaspe, Quebec. 
In the first two of these localities the geological relations of 
the rocks are obscured to a high degree. The country is heavily 
drift-covered, and most of the rocks are possessed of a strongly 
developed slaty cleavage, which in many cases renders the 
correct interpretation of the structure of rock masses very dif- 
ficult. Moreover, the rocks have been subjected to metamor- 
phism more or less severely, so that their original characteristics 
are somewhat changed. Taking all of these considerations into 
account, it is to be wondered at that the workers in this field
