north ; as already noticed the argillites do not contain nearly as 
much pyrite as the gneissoid strata. The argillites continue 
a long distance north, but are covered by the Pleistocene forma- 
tion. Their dip is vertical. There appears to be more crystals of 
quartz in the veins of this part of the Cambrian than in the 
egneissoid strata, but perhaps this may not be the general rule but 
only the ease in this locality.

Quartzites.—The quartzites occupy a large part of the district. 
The Pleistocene does not cover them as it does the argillites and 
eneissoid rocks. The dip of the quartzites is about from 18 ° 
22°. The strike differs a great deal, varying from N. 15° E. 
to N. and S. invenetic. They appear to have been much more 
disturbed than either the gneissoid rocks or argillites. Faults 
appear to be very frequent. 
PLEISTOCENE. 
This formation overlies the Archzean in some places and covers 
a great part of the Cambrian. It consists largely of granite 
syenite, porphyrite, diorite, dolerite and quartzite, amygdaloid, 
schist, chert and conglomerate boulders. 
At Pulsifer’s some years ago was found a beautiful hematite, 
which Dr. Honeyman said had come from the Londonderry Mines, 
and it has been satisfactorily proved that he was correct, both 
by the striation and by the boulders accompanying it, which 
were diorites, syenites and amygdaloids, especially the diorites, 
? 
which were very hornblendic and contained oligoclase (soda 
feldspar). One specimen which I found is very beautiful and 
contained a little mica and pyrite. These, without doubt, came 
from the Cobequid Mountains. 
The specimen of brown hematite has exactly the same streak 
as the Londonderry iron, and cannot be distinguished from it by 
any test. The specimen is a very fine one, weighing five pounds 
and a quarter. It is beautifully crystalized. The structure is 
mammillary, very compact. 
At Indian River, St. Margaret’s Bay, I found great quantities 
of granite which very much resemble syenite. At North-East
