44 THE GEOLOGY OF BELLEVILLE 
part of the Trenton series. This bed, pointed out to me, by Campbell 
Wallbridge, Esq., of Belleville, contains numerous impressions of 
strophomena alternata and other Trenton forms, and is thus (as shown 
moreover by its position amongst the shaly limestones) a true member 
of the group. It is the first example of this kind of association that 
I have met with in the Trenton Series, but a similar interstratification 
of clay and limestone beds has been seen, I believe, in other places. 
About Belleville, the most prolific fossil localities are the river banks, 
and an old cutting for a mill-race on the east bank of the river, a little 
north of the Railway Station. The banks of the river (the Salmon) 
at Shannonyille, and a cutting on the Railway at that place, about 
half a mile west of the Station, are also good localities ; whilst around 
Trenton village many excavations and small quarries will be found ex- 
ceedingly rich in fossils. On the steep side also of the high land at 
Rednersville in Prince Edward’s County, some good specimens may be 
procured. This is the highest position occupied by the Trenton 
Limestone immediately around Belleville. I was led to understand by 
persons residing in Belleville, that the rock was not limestone ; but it 
consists simply of the same shaly limestone as that seen on the banks 
of the Moira, as shewn in the following section (lettered as in figure 
1), from which moreover, an idea may be gleaned of the vast amount 
of denudation which must have taken place in that neighbourhood, 
both before and after the deposition of the Drift.

At some of the above mentioned localities, and especially in the 
old mill-race near the Railway Station at Bellevile, I found Oolumna- 
ria alveolata, until recently considered typical of the Black River 
Limestone, associated with ordinary Trenton fossils; and near the 
Episcopalian Church at Shannonville, I found the same coral with 
Stromatoceriwm rugosum, also accompanying Trenton species. These 
types therefore, (as already shewn by Sir William Logan and others,
