Lubec Peninsula.
July 3, 1907 (Wednesday).
along the shore southwest of Lubec Bluffs
light there extend for a mile southward from
Woodwards Court a series of exposures of
massive dark slate slabs with on their
imined thin calcareous seams; and in some
portions of the slates these have become
concretions which have been weathered
out leaving empty holes. The slates
are metamorphosed shales of a dark
blue color which have nearly lost their
cleaving planes and which are extremely
friable. Most of these fissures extend in
one direction, & are frequently very close to
gether giving more or less perfect slaty
cleavage. Besides this slaty cleavage there
are also several series of joint planes; these
numerous joint planes traverse the plane
& dark color together with the even
texture cause the rock to resemble at
first sight a massive much jointed trap,
and the result cleavage is masked by them.
very total absence of bedding planes in
the more massive portions. The presence of
calcareous seams above the upper edge
of the rock which also inflates along
more or less distinct banding. (For
strike & dip see C.S.B's notes).
A search was made for fossils in these
slabs to half a mile, as well as in the
slate shales. At the southernmost
edge a mile south of Woodwards Court
occurs but at two traces of fossils result.
big fish bones or wood fragments and three
or four linear deposits of mineral which
may be pseudomorphs of graphite. These
workings are C.S.B.
No evidence in
favor of their fossil character is chiefly the
structure strictly parallel to the bedding plane
of the rock, and their more or less regular
banding. The evidence against the
graphite nature of the fossils so called
