Horizontal columns structure the
above trends N.53° E. and re-separ-
at-ed from the top by a 3 foot feature
running N.53°E. and describing a
fault. The feature is in pieces composed of
green shales leaving truly a fragment
of large lamellibranch (first collected)
and striking N.23°E. shales vertical,
comparable with Rodgers Island beds:
gabbro dike at northern end.
1106 = gabbro- underneath of redway
north of No. tube dry wharf south of
factory. The gabbro continues to far
sea Reynolds Cove.
In the little cove in central
6.24.7, a reconnaissance
in company with Dr
Austin shows that the
laur dikes 1093(page 24)
are gabbro, and the
so called acid volume
1092 is an ashore contain-
ing fossils in a seam.
This ashore is unrolled,
massive, and over 50 ft.
blocks apparently and
contains in the lower
part of the seam one to
5 inches thick in which
Dr. Austin discovered some
Platystearina- the gastropoda edge of clam
rubs an inch thick. Else where he
contains some large lamellibranch with
by students description of megacoma in
outline. Here fossils 6.24.7c. The
massive upper side of 6.24.7 b may be
the same: the fossiliferous seam is a
very nearly horizontal dipping bed
on an eastwardly.
It rocks in
a tuff, including angular small
angular fragments of pink rhyolite
and rounded gabbro of raw labrum
with (4 to 5 inches) where)
of gray
rock of limestone. Below this the
rock resembles that called dolomite
in Brick Point = 1107 which also-
the rock is mottled and includes
small angular bits of pink rhyolite.
= 1108.
1109 is the lauri dike on the
northwest side of the cove.
The acid 1092 is a dike the re-
latures of which are
shown in the ac-
companying sketch.

Pleasant Point (cut. from notebook
I pp.15, 20.)
On the west side of Pleasant Point
beginning at the cape in 3.33.7
where occur alternations of rhyolite
(1076) and gabbro(1077). We find a large
mass of gabbro followed by an
extensive series of exposures of red and
grey shales flag, some dust beds.
From Colon upward and passing
northwestward we find
(a) 4 ft. grey beds. Alternations of thin
flossy seams 3/4" thick with gray
porous shales of similar thickness.
A foot layer 2 inches thick upper
part.
Strike S.70°W., Dip 35°N.20W.
