24 NOVA SCOTIAN GEOLOGY—HONEYMAN. 
seemed, however, to have re-entered the Pre-carboniferous area. 
Reaching Vaughan’s Mill, Greenfield, we found a magnificent 
exposure of pre-carboniferous rocks, having lithological characters 
widely different from the other rocks of the area. The resem- 
blance of these to the black argillites of Halifax and Dartmouth, 
is sufficiently obvious. I felt no hesitation in regarding them as 
the north side of the great Cambrian series of our gold fields. 
Looking to the heights beyond we observed massive granites 
which seemed to indicate solid granite underneath. Traversing 
these in passing on from Vaughan’s Mill to Bezanson’s Mill, on 
Black River below the lake, we found outcrops of black argillites, 
the enormous and frequent occurring blocks of granite being 
only transported rocks, derived from granite outside of area, and 
not yet examined. At Bezanson’s Mill the black argillites were 
seen outcropping. Gneissoid and granite specimens were collected 
from rocks not in situ—precisely like the Halifax—granite and 
eneissoid rocks. 
We then followed nearly the course of the Black River, observ- 
ing the fine exposure of argillites at Payzant’s Mill, and occasional 
outcrops between this and the Falls. Before reaching the Falls 
we ascended the mountains on the right observing occurring out- 
crops of metamorphic rocks, and thus crossed the area to its 
border at Gaspereaux River Bridge. We then proceeded along 
the road that leads up the river, on the Wolfville side, towards 
the Deep Hollow, observing the extent of the quartzites already 
referred to. We passed through the Deep Hollow and emerged 
from the area described at its N. W. Corner. This examination 
led to the conclusion that there are two series of pre-carboniferous 
rocks in the area, viz.: Cambrian and Lower Silurian, which 
may be locally characterized as Greenfield, Wolfville. 
The second area examined is about } of the size of the preced- 
ing one and much more irregular. It begins at Kentville, the 
first strata being exposed at the mills, a little above the bridge, on 
the side and in the bed of the brook. At the great dam a little 
farther up, they are considerably exposed on either side; a little 
above this they disappear in the brook giving place to outcrops 
of another formation. They are again seen in a limited section
