62 NOVA SCOTIAN GEOLOGY—HONEYMAN. 
rock with the same strike and dip. The ledges on the east side 
of Point Pleasant are a continuation, these are generally argillites. 
9. At Pleasant street, not far from the Park, there are beautiful 
exposures of argillite strata. Coming to the shore on the opposite 
side we find a great ledge of similar strata. At the side and back 
of these are argillite shales and massive quartzites with veins 
of quartz, all the three pass into each other insensibly. In the 
gold fields argillites are seen when mining where the surface 
would lead to the expectation of only quartzites. 3. The Caleareo- 
quartzites are a striking illustration. I first observed these on 
the shore between Cow Bay and Cole Harbour. When walking 
along the shore, I was surprised to find certain rocks singularly 
worn, as I have seen Lower Carboniferous Limestone worn on the 
sea shore, by the action of the waves, while other parts of the 
same rock had the usual appearance of the hard quartzites exposed 
to similar action. I found in subsequent chemical examinations 
that 18 per cent of the highly worn parts of the rock was cal- 
careous, while the other parts were quartzite. The acid only 
can indicate the passage with precision, which is gradual, the 
sea indicates it approximately. Similar rock and indications 
are observed on the Eastern Passage, opposite Lawlor’s Island- 
The constitution of the original sediment and accident are doubt- 
less the causes of the variation. The series, therefore, is not divis- 
ible into subordinate members or groups. 
SYNCLINAL. 
On the East side of Pleasant Park, at Steele’s Pond is a point 
where there was in olden times a Three Gun Battery. The rocks 
of this are exposed on the shore, and exhibit interesting structure. 
They are seen to dip on the right to the South and on the left to 
the North. In the centre the strata are bent so as to display a 
series of parabolic curves. A photograph of this taken by the 
photographer of H.M.S. Challenger for Sir C. WYVILLE THOMSON, 
is a very striking picture. 
SECTION. 
On the right or north of the Syncline the argillite strata 
become confused, they then become shaly. In the shales I found 
forms which at first sight seemed to be graptolite stipes but
