APPENDIX 13. — REPORT OF GEOLOGICAL COMMITTEE. 
Xlll. 
In the centre of the St. John Basin the thickness of this 
division, especially of its upper part (Section c), is greatly 
increased. The whole division there counts about 1,000 feet 
of measures. It is visible on the east side of Courtenay Bay, 
from its head to the Alms House brook. In the Old City it 
forms a broad belt across the centre, bounded on the north 
by a line from Union street east, to the Carleton Ferry, and 
on the south by one from Orange street east, to Heed’s Point. 
On the west side of the harbour it rises prominently into a 
ridge at King’s Square, south of which its width extends for 
the space of one block (or square). 
Division 3 , or Bretonian Stage . — This division includes 
at the summit a small thickness of beds, which belong to the 
Ordovician system ; but although not Cambrian, they form 
a part of the St. John Group, and are therefore included in 
this statement. 
The Bretonian consists entirely of fine shales of dark color, 
much of it being intensely black and carbonaceous. It con- 
tains three faunas and so marks the passage of a long interval 
of time.

These soft rocks lie in the valley along the boundary line 
between the Old City and Portland (“ South End and North 
End,”) and extend thence through the harbour to the “ Falls ” 
of the St. John River where their thickness is seven hundred 
feet. Another belt of the rocks of this division extend across 
the citv from Market Square and Water street north, to St. 
David’s street on Courtenay Bay. The rocks of this division 
always occupy low land, except on the south side of “ the 
valley,” where they rise on its southern flank, crossing Jeffrey’s 
Hill, and extending to the City Hospital, etc.
