Parrsboro, July 7 1912.
Spent the morning seeing the exposures along the
East side of Chest Bay. Did not go out to the eastern
point to see Toranic trip and red shales and sandstones.
Next to the Toranic according to Fletcher is the
Devonian that at first (the highest beds) consist of some
red shales that seem pass into carbonaceous shale and
greenish shales. In those dark beds near the top occur
Estheria and Levia that are at times very common.
Rarely is seen a small bivalve and a few specimen
of a <crustacean> little they occurs associated. Lower
down small bivalves are very common. In between
the prodifurms layers the great mass of these beds
consists of reddish clays that are throughout well-
crusted. Ripple marks are seen almost at all levels.
This entire series consists of very shallow mud flat de-
posits, evidently in connection with the sea but at
no time are they true marine deposits. On the basis
of the Levia these deposits must be Pennsylvanian
age. These beds are continuous with what Fletcher
calls "Carboniferous limestone". Farther westward along
the line these shales are terminated unconformably by a
<brick-red>
and serpentine
craze boulder conglomerate that may be 10 foot thick.
Hyde thinks it may be of a younger series unconformity
resting on the Pennsylvanian beds but could not make
