do not, so far as J have observed, occur at all, and the schis- 
tose rocks arc not found cast of long. 118°. 
Comparing our observations with the admirable work of 
Mr. MeConnell in Bow pass, we may conclude thai the chief 
fossiliferous beds observed, Upper Devonian according to Mr. 
Walker's determination of the fossils, correspond to the Banff 
limestone of Bow pass, there considered Lower Carboniferous 
or Upper Devonian. The species of fossils referred to by 
MeConnell, "a Ithynchonella like Rocky -Montana, another 
like 11. metallica, Atrypa reticularis, a Spirifera like 8. Whit- 
ney i, also species of Athyris, Productus, Lichas, Eridophyllum, 
and Diphyphyllum"* are in general like those obtained along 
the Brazeau and neighboring streams, but they do not appear 
to agree very closely. Whether the oolitic limestones found 
at several points in our region correspond to McConnell's 
( astle Mountain group, which is Cambrian,! cannot be settled 
until fossils are found. The only instance Where fossils do 
occur, not in the oolite but near by, is near Brazeau lake, 
about 8,000 feet above the sea level, where a Proetus closely 
allied to P. nevadce is found, probably Devonian. 
MeConnell describes the shales associated with the Banff 
limestone as passing into sandstones and quartzites. Whether 
the, thousands of feet of similar rocks observed by us, forming 
independent mountain ranges, as along the Sun-wapta, or un- 
derlying the limestones in other parts, are of the same age, it 
is impossible to say. 
We found no equivalent of McConnell's Halysites beds. J 
The structural features described by MeConnell in Bow pass 
correspond in general to those along the Brazeau, but of 
course details are entirely different. 
It will be of much interest to compare the region described 
in this paper with that along Howse pass traversed by Me- 
Connell in 1<S92. His work will doubtless afford material for 
connecting and completing our fragmentary investigations. 
A brief reference should be made to the superficial geology 
of the region traversed. Evidence of glacial action is wide-
