76 GLACIAL GEOLOGY OF NOVA SCOTIA—HONEYMAN, 
generally of Lower Cambrian quartzites. Among these, however, 
we find abundance of beautiful boulders of Archzean syenites, 
syenitic gneiss, porphyrites, &c., and also Triassic amygdaloids. 
Out of these we made up our collection of 25 specimens. 
DARTMOUTH RAILWAY. 
Several years ago I fully investigated the Glacial Geology of 
this side of the Halifax Harbor, and recorded my observations in 
the Transactions of the Institute. As in other parts of the 
province, a line of railway has been constructed here, which 
enables me to improve previous work. The great drift accumu- 
lations which contribute to the picturesqueness and roughness of 
the eastern side of the harbour have been exposed more than 
formerly. Two fine new sections are particularly instructive. 
We have now three good sections. The first is an old section of 
the eminence on which Judge James’ residence and grounds are 
situate. This was our chief key to the geology of the moraine 
previously. The section is near the line of railway, not on it. 
There was nothing new observed here. It is on the north end 
of the accumulations. Walking along the railway (S.) we reach 
Mott’s factory. On a field to the south of it, we have the first new 
section. Here I found abundance of boulders of Archean rocks, 
such as we have already named, and several boulders of basalt 
(dolerite) and an amygdaloid. I took specimens of these to form 
a new representative collection. ‘The next section south of 
Troop’s wharf is more varied and of looser material than the 
preceding. A prominent constituent is a coarse red_ brick 
clay. This is a section of a beautiful green field belonging to 
Dr. Parker and others. Here were abundance of the usual Arch- 
wan boulders and also Triassic. In the clay I observed, partly 
projecting, an amygdaloid of grey colour. It was found to be of 
large size, the remainder of it being deeply imbedded in the clay. 
Other amygdaloid boulders of various sizes and replete with 
beautiful amyedules of heulandite were also found imbedded in 
the same clay. Of these I took specimens, leaving the remains 
for other collectors. The collection from these sections contains 
19 specimens. I would here make a remark which is applicable
