NO. 1487 A2 — BRISTOL HILL. 
At the eastern end of the first railroad cut, west of Bristol church, 
are exposures of fine, blocky, blue shales, in which Hamilton fossils 
are abundant, the specimens being more numerous than in any of the 
other outcrops along the line of the railroad. In the long railroad cut 
to the west, after crossing the trestle, some of the sandstone layers 
show a dip of between 4° and 5° to the west; while exposures south of 
the railroad, at the western end of the cut, show that the dip is prob- 
ably to the northwest.
