NOVA SCOTIAN GEOLOGY—HONEYMAN. 233 
Cape St. Mary and Meteghan is dependent upon the resisting 
power of the diorite. It has been an effective breakwater in the 
past as it is in Cape Cove at the present. Beyond the cove are 
flats, swamps and meadows. About a mile from the cove the 
eround becomes elevated, and black slates are seen outcropping 
containing veins of white quartz. As seen at Z. Deveu’s they are 
not distinguishable from the black slate of Cape St. Mary with 
milky quartz already referred to. At this time I was not aware of 
their true character, I supposed that they corresponded with the 
Cape St. Mary’s strata, considering that the two formed an anti- 
clinal having the diorite for its centre. Dr. Selwyn seems to con- 
sider the Cape St. Mary’s slates as corresponding in age with the 
black slates of Jebogue Point. In regarding them as corresponding 
with Deveu’s black slates, I was unwittingly and indirectly doing 
as Dr. Selwyn‘had done, while I was regarding both as occupy- 
ing the lowest position in the Middle and Lower Silurian: 
series of Moose and Bear River. On the following day I re- 
urned to Yarmouth expecting to resume investigations at Cape 
Cove, with a view to the further filling up of the railway gap, 
the extension of the quartzite succeeding not yet having made 
its appearance on the shore. 
YARMOUTH. 
-.I1 have to acknowledge my obligations to the Hon. Loran E. 
Baker and S. M. Ryerson, Esq., for making arrangements by 
which I was enabled to make a very satisfactory examination of 
a considerable extent of the interesting rocks of Yarmouth and 
Digby in a comparatively short time. 
‘SUNDAY POINT. 
This was the first place near Yarmouth that I examined. 
Mr. Ryerson took me there. The rocks at this point are very 
interesting, they are Por phyrite and Diorite. 
This is the first time that I have seen porphyrites and dioninel 
in our auriferous formation. They have been frequently found in 
the Archean and later formations, at Arisaig, the Cobequid 
Mountains, McLellan’s, Sutherland’s River Mountains. -Diorites
