Quadrille Ruled Form. Patented 1906. John C. Moore Corporation, Rochester, N. Y.
Back of the house of Mr.Saunders,
the hill in northern 8:31:3/6 is com-
pos ed of the greenish shales,or
tuffaceous shales, highly slated.There
is a little blue glassy rhyolite.
The south shore of East Stream in 8;31;3
is composed of highly slated shales,
supported on th east by a hillock of
rhyolite. The slaty cleavage trends
N.57 degrees east, and is nearly vertic-
al. The bedding is very indistinct. It
appears to strike N.5 degrees east
and dip west at a very low angle, but
this appearance may possibly be due to
jointing.
The slates are cut at the "Narrows"
in the western part of 8:31:3 by a
20-foot gabbro dike.
The slates reappear beginning in 8:31:2
eastern quarter, where the cleavage trends
N.60 degrees east and is nearly vertical
(dips 85 degrees south-east). Here again
there are many planes developed striking
N.8 degrees east and dipping west at an angle
of 33 degrees. These appear to
represent strike and dip. The slates
continue as far as Moon Brook, and are
cut by two gabbro sills, the eastern
one extending N.E., and the western
one, a dike, trending N.50 degrees west.
The little bay about Moon Brook 8:31:1
is gabbro excepting the northwest corner
where a strip of slate appears. To the
west, the gabbro again appears on the
rounded little point in eastern 8:31:1.
The gabbro contains here long black lathes
nearly a centimetre in length(hornblende?)
and on the east margin has lavenderish-
