GEOLOGY OF ANTIGONISH COUNTY—HONEYMAN. 319 
at least Lower Silurian. In my Paper “On the Geology of 
Antigonish County,” Trans. I. N. S., 1866, we thus read, “ Hall’s 
noble work on the ‘Canadian Graptolites, has led me to consider 
that there is yet something to be done in the correct deter- 
mination of the equivalency of the ‘Arisaig Group, as the 
graptolites of B appear to have the facies of the graptolites of 
the ‘Hudson River Group, so that A. B., may be the Arisaig 
equivalent of this group.” Instead, therefore, of beginning with 
the Upper Silurian age, it may begin with part of the Lower 
Silurian. During the course of my investigations, I have found 
it impossible satisfactorily to correlate series of rocks which are 
evidently identical in their paleontology with A and B, on the 
supposition that these are of any other than Lower Silurian age. 
My examination of the Utica formation of Ottawa convinced me 
that they are equivalent to this. In the beautiful collection of 
the graptolites from the Isle of Orleans, presented to me by 
Dr. Hill, of Ottawa, as well as in the fine collection of graptolites 
from Moffat, Scotland, presented by John Dairon, Esq., Glasgow, 
I recognize the facies of the Doctor’s Brook graptolites. I am 
therefore forced to conclude that B is of Lower Silurian age. 
The paleontology of A is also of the Utica formation.* 
Underlying A is a highly metamorphic and non-fossiliferous 
band of rocks (a) in contact with trap. These extend (with 
breaks) from Arisaig Pier to the neighbourhood of MeNeil’s 
Brook. They occupy the same relative positions as band No. 6, 
already described, and have in like manner been much affected 
by the igneous rocks with which they are associated. 
The difference in the lithological character of the two may be 
accidental. Here we have sandy shale poreellainized and con- 
verted into jaspideous rocks, as at Arisaig Pier, Frenchman’s Barn 
(rock) and near MeNeil’s Brook. These rocks of quartz hardness 
are associated with others which have a serpentine aspect, and 
a hardness corresponding. The latter have attracted some

these views. He considers them to be of Hudson River age. He also consi-
