food and a ball is exposed immedi-
ately under, the slate; the upper
surface striking N. 48° W. and
dipping 32° & 50° N. 42° E. A speci-
men is 1139. After a covered dip of
slate and 25 feet the same kind of
staff reappears to the west in a
compact mass which shows no
cracking planes and which ex-
tends for 70 ft. I compute thickness
at 32° dip, and add 10 feet for light of
exposure. A specimen at 1140.
In place the material is rough,
blue in patches; blocks light creamy
brown. Foot trace of bedding is des-
cernible. There massive trachyolite
against a mass of very coarse
gabbro—1141—which is exposed in
large concretionary nodules one
foot to two feet thick with an even,
snow rounded mass, 4 feet thick.
This gabbro resembles a dark
granite. The feldspar is well developed
purple.—The width of outcrop is about
50 feet. The gabbro appears to be a sill
with general inclination similar to
the lying sediments.
About 20 feet of the massive
entirely unbedded triff or volcanic
ash seems to lie west of the gabbro
similar to that to the east. A specimen
is 1142. Fragments over an inch or 2
nearly 3 inches, are exceedingly num-
erous.
After a covered interval of 15
feet made through some
stratified gray flags and thin
volcanic ash seems striking
N. 35° W. and dipping 40°, N. 55° E.
The rock is grayish above but
becomes purplish below. The
ash seams are usually half an
inch or less, the flags to 2-6 inches,
one ash seam runs the middle
is a foot thick and rather purpl-
ish—1143. This series must be
about 20 feet thick.
It overlies some massive
entirely unbedded ash 1144, which
is about 20 feet thick and this
overlies a very dark purple rhyolite
glass unbedded massive possibly a
tuya—last grades upward into the
ash—1144. A specimen is 1145.
Its pigmentary between Selmon
as East and Long Cove
is composed of black cones of
gabbro which is very coarse and
ark across some volcanic
tuffs. These tuffs are
generally purplish color
and with purplish
ash fragments, some
with similar in general
way to those near
Head of Blackford.
These tuffs are
massive & without any
stratification planes. Very
20 feet thick is very
fine glass below to column-
lar purplish rhyolite
which is underlying &
an irregular mass of
volcanic mud exposed
west the top two mark 184.
The east slope of Long Cove.
This volcanoes must be much
smaller by a few miles (5 or 6) of
volcanic tuffs.
